Background
The intrusion alarm system is widely applied to a plurality of fields such as army, bank, museum, industrial and mining enterprises, public security and the like, and at present, the space intrusion alarm system commonly used at home and abroad mainly adopts a passive infrared intrusion detector, a microwave intrusion detector and a dual-technology intrusion detector (the combination of passive infrared and microwave).
The above alarm systems all have their specific conditions of use, all have certain limitations from the installation and use angles of the detection device, for example: the passive infrared intrusion detector has the detection method that the change of the thermal radiation in a certain three-dimensional precaution space is monitored, and when a human body moves in a detection range, the level of the received infrared radiation is changed, so that the alarm is triggered. The passive infrared detection method is easily interfered by various heat sources (air conditioner, cold and hot air convection) and light sources, but when the ambient temperature and the human body temperature are close, the detection and the sensitivity are obviously reduced, short-time detection failure is sometimes caused, and the detector also fails when a shelter (a heat insulation object such as a large umbrella, a raincoat, glass and the like) is used for blocking the body. Active intrusion detectors such as microwave intrusion detectors and dual-technology intrusion detectors can avoid the above weaknesses by adopting the doppler principle, but have a high false alarm rate, and the devices can be detected only after being fixedly installed and debugged, and cannot be movably installed and deployed at any time.
The detection method of microwave correlation comprises the following steps: the microwave transmitting end transmits microwave signals to the precaution area through the antenna, and when the precaution area does not move the target, the receiving end receives the complete microwave signals and does not give an alarm. When the prevention area has a moving target, the effective target can reflect, absorb and block microwave signals because the microwaves have heat effect and reflection effect, and the receiving end generates alarm signals after analysis. Although the microwave correlation detector can avoid the defects of the equipment, the microwave correlation detector generally needs to be fixedly installed and cannot be rapidly deployed, and even if the microwave correlation detector is rapidly installed, cables must be adopted to transmit power and signals, so that the problems of low deployment efficiency, poor concealment and the like are caused.

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
As shown in fig. 1 to 10, the mobile rapid deployment guard system of the present invention is a defense area type intrusion alarm device, and the length of the defense area 1 may be 5m to 200 m. The mobile rapid deployment guard system comprises a detection unit and a receiving unit, wherein waves in the detection unit are oppositely emitted to form an invisible microwave detection field 2, so as to detect the invasion behavior of an invader walking, running or crawling into a defense area, and the detection unit comprises 1 set of microwave opposite emission unit 6, a multifunctional tripod 9 and a low-temperature-resistant lithium battery; the receiving unit is responsible for receiving, displaying and forwarding the alarm signal, provides alarm display and output, can be a wireless remote sensing control terminal 8, and can also be a mobile phone client adopting a mobile communication internet client or a PC client accessing the internet.
In the invention, a detection unit is provided with a plurality of groups of microwave transmitting ends 4 and microwave receiving ends 5, each group of microwave transmitting ends 4 and microwave receiving ends 5 which are paired and oppositely emitted form a microwave oppositely-emitting unit 6, and the microwave transmitting ends 4 and the microwave receiving ends 5 are both arranged at the edge of a defense area 1; the plurality of microwave correlation units 6 are used for forming the defense area 1 by integrally forming regional microwave electromagnetic fields through microwave correlation. The specific setting mode is as follows: a plurality of defense deployment points 3 are arranged in the defense area 1, a microwave correlation prevention area is formed between every two adjacent defense deployment points 3, and a microwave transmitting end 4 and a microwave receiving end 5 are both arranged in the defense deployment points 3; each microwave correlation prevention area is provided with a group of 1 microwave transmitting end 4 and 1 microwave receiving end 5 which are paired; the microwave correlation prevention areas are connected in a cross way end to form a closed-loop microwave detection field 2 to protect the defense area 1.
In the present invention, both the microwave transmitting terminal 4 and the microwave receiving terminal 5 are provided with a plane radiating element matrix antenna, and the planar radiation element matrix antennas are small in size and light in weight relative to the parabolic antennas, the planar radiation element matrix antennas are fixedly arranged in the microwave correlation equipment, and each planar radiation element matrix antenna is provided with an angle with set parameters, so that the angle change of the antennas cannot happen even if the equipment is frequently disassembled and boxed. Therefore, the problem that the antenna needs to be adjusted for a long time during installation to obtain a correct microwave beam signal can be solved.
The control plane radiation unit matrix antenna can be rapidly deployed and detected. When a group of microwave transmitting terminal 4 and microwave receiving terminal 5 which are paired and adopt the planar radiation unit matrix antenna are installed quickly, only the microwave equipment needs to be aligned visually without operations such as adjusting the angle of the antenna, and the planar radiation unit matrix antenna is controlled to enter a detection state by a built-in program. After the equipment is powered on, the detected microwave carriers transmitted by the planar radiation element matrix antenna are communicated with each other, signals of microwave communication are analyzed by an internal program of the equipment to confirm the distance between the two pieces of equipment and the angle between the two antennas, and then each radiation element in the planar radiation element matrix antenna at the microwave transmitting end is controlled to obtain correct microwave beams, so that the microwave correlation equipment can rapidly enter a detection state. When the correctly installed microwave correlation equipment is electrified and enters a defense deployment detection working state, the overall time is less than 10 seconds, and therefore rapid deployment is achieved.
In this embodiment, each defense deployment point 3 is provided with 2 microwave transmitting terminals 4 or 2 microwave receiving terminals 5, and two adjacent defense deployment points 3 are respectively provided with a microwave transmitting terminal 4 and a microwave receiving terminal 5, namely: the first defense deployment point 3 is provided with 2 microwave transmitting ends 4, the second defense deployment point 3 is provided with 2 microwave receiving ends 5, the third defense deployment point 3 is provided with 2 microwave transmitting ends 4, the fourth defense deployment point 3 is provided with 2 microwave receiving ends 5, and so on. Microwave transmitting ends 4 and microwave receiving ends 5 of two adjacent defense points 3 are in one-to-one correlation to form a microwave correlation prevention area, a pair of microwave transmitting ends 4 and microwave receiving ends 5 which are in mutual correlation to form a microwave correlation unit 6, and the whole microwave correlation prevention area is formed into 4 microwave correlation prevention areas and forms a closed-loop microwave detection field 2.
In operation, the plurality of groups of microwave correlation units 6 form a regional microwave intrusion detection electromagnetic field, namely the microwave detection field 2, through the microwave electromagnetic field. After the microwave correlation unit 6 is properly placed, the microwave correlation is aligned visually, and it is ensured that no obstacle (which may cause false alarm) or ground depression (which may form a blind area) exists in the microwave beam region; switching on power supplies of a microwave transmitting end 4 and a microwave receiving end 5, enabling microwave correlation to communicate with each other through microwave carriers, firstly entering a self-checking state, and confirming that the devices are normally paired and debugged; and then the microwave correlation unit 6 enters an automatic distance correction state, the distance between the microwave correlation unit 6 and the transmitting end is confirmed through microwave carrier communication because the propagation speed of the microwave in the air is a fixed value, and finally the microwave correlation unit 6 performs automatic gain adjustment according to the determined distance to adjust the transmitting power of the transmitting end. If the signal with the correct intensity cannot be obtained after the transmitting power is adjusted within the determined using distance, the microwave correlation can continuously give an alarm to prompt until the microwave correlation unit 6 is arranged to be correctly and accurately aligned, so that the microwave signal with the correct intensity is obtained.
In the invention, each set of microwave correlation unit 6 comprises 1 microwave transmitting end 4 and 1 microwave receiving end 5, and the arrangement distance of the microwave correlation units 6 can be arranged between 5m and 200m according to the field environment. As shown in fig. 2, the microwave emitting end 4 emits microwave energy to form a microwave electromagnetic field with narrow ends and wide middle (the beam width is 4% of the beam length), which is invisible. The microwave receiving end 5 continuously receives microwave energy, detects activities in a microwave electromagnetic field, any invasion behaviors of interfering, reflecting and blocking the microwave electromagnetic field change signals received by the microwave receiving end 5, the microwave receiving end 5 processes the changed signals to distinguish other invasion behaviors of an invader such as walking, running and crawling, and an alarm is triggered when the signals meet judgment conditions of effective targets.
The microwave correlation alarm conditions are as follows:
1. under normal conditions, microwave correlation can detect intruders with speed between 3 cm/s and 15 m/s;
2. in the range of 200m, the microwave correlation can detect the invasion of an invader in a walking, running or jumping way;
3. in the range of 150m, microwave correlation can detect the invasion of an invader in a mode of walking, running, bending knees, crawling or jumping;
4. in the range of 100m, the microwave correlation can detect the invasion of the invader in the modes of walking, running, bending knees and crawling, creeping, rolling or jumping;
5. the microwave receiving end 5 only receives microwave signals transmitted by the paired microwave transmitting ends 4, and if the microwave signals are cracked by malicious intrusion, the system triggers an alarm;
6. if any one of the units is damaged and stolen, the microwave signal is lost and interrupted, or the microwave signal is interfered by an intruder, the system triggers an alarm.
When an intruder enters the microwave electromagnetic field in walking, running, crawling and other postures, the microwave has a heat effect and a reflection effect, the microwave electromagnetic field is interfered by the human body because the microwave has constant microwave absorption and reflection amount, and in addition, the walking, running and crawling postures of the intruder appear at different spatial positions of the microwave detection electromagnetic field, and microwave signals with different intensities and positions can be received on the antenna at the receiving end. The characteristic signal data formed by these intrusion behaviors (but not limited to the above behaviors) is stored in the memory of the receiving end. Due to the weather conditions such as rain, snow and fog in the external environment or electromagnetic interference generated by other equipment, continuous background environment noise interference can be generated on the wave beams of the microwaves, and the background environment noise can interfere with or even shield the intrusion signals to influence the accurate judgment of the receiving end on the intrusion signals; therefore, when the receiving end receives the effective intrusion signal, the intrusion signal is firstly analyzed by the digital signal processor to be separated from the background environment noise to obtain a real intrusion signal, then the real intrusion signal is compared with the stored intrusion characteristic data, and when the signal meets the judgment condition of an effective target, an alarm is triggered.
When the microwave is lost due to the influence of weather conditions, such as rain, snow, fog or rapid change of outdoor air temperature, the transmitting end can also adjust the transmitting power through the automatic gain to compensate. The transmitting antenna and the receiving antenna of each microwave correlation unit both adopt flat-plate microstrip antennas, so that the directivity of the antennas is excellent, the volume of the microwave units is reduced, and the power consumption is reduced.
In the invention, the microwave transmitting end 4 and the microwave receiving end 5 work in a 24G frequency band, and the frequency band can be divided into 10 bands of detection frequencies for selection, so that a plurality of sets of microwave correlation devices can work in a short distance without mutual interference.
Data communication between the microwave transmitting end 4 and the microwave receiving end 5 adopts the modulated microwave detection signal as a carrier wave for communication, and a communication cable does not need to be additionally arranged. The receiving unit comprises a wireless alarm module 7, a wireless remote sensing control terminal 8 or a mobile communication internet client, an alarm signal generated by the microwave receiving end 5 is sent to the wireless remote sensing control terminal 8 through the wireless alarm module 7 arranged in the receiving unit, and the wireless remote sensing control terminal 8 displays and outputs the alarm signal; or the wireless alarm module 7 sends the alarm signal to the mobile communication internet client, and the mobile phone client, the tablet computer client and the PC client display and output the alarm signal, namely the mobile communication internet client can be a mobile phone client, a tablet computer client and a PC client.
The microwave transmitting end 4 and the microwave receiving end 5 are both fixedly mounted through a tripod 9, as shown in fig. 3, the tripod 9 includes a battery compartment cover 10, a quick mounting interface 11, a central support column 12, a telescopic support column 13, a power line 14, a tripod support column 15, a telescopic support column locking nut 16, a fixed support 17 and a fixed nail hole 18.
During installation, the microwave transmitting end 4 and the microwave receiving end 5 are inserted into the quick installation interface 11 at the upper part of the tripod 9, and the microwave transmitting end 4 and the microwave receiving end 5 can be locked and fixed by the lock catch of the quick installation interface 11 after the microwave transmitting end 4 and the microwave receiving end 5 are inserted in place.
The central support column 12 of the tripod 9 is a cavity structure, the internal cavity of which directly forms a battery compartment in which a low temperature resistant lithium battery 19 for supplying power to the equipment is directly installed. When the battery is replaced, the low-temperature resistant lithium battery 19 can be taken out and replaced only by unscrewing the battery bin cover 10 on the upper part of the central support column 12. The microwave transmitting terminal 4 and the microwave receiving terminal 5 are connected with a low temperature resistant lithium battery 19 through a power line 14, so as to provide electric energy.
The tripod 9 comprises three tripod support columns 15, and a telescopic support column 13 is sleeved on the lower part of each tripod support column 15 and is used for the following two points:
1. when the ground where the microwave transmitting end 4 and the microwave receiving end 5 are placed is uneven, the length of the three telescopic supporting columns 13 can be adjusted to ensure that each microwave transmitting end 4 and each microwave receiving end 5 are in a horizontal state, so that the detected microwave beams are aligned between the microwave opposite emission units 6, and false alarm or missing alarm caused by microwave beam deviation can be avoided.
2. Because the detection beam characteristics of microwave correlation are narrow at two ends and wide in the middle, a certain microwave coverage blind area is generated near the microwave transmitting end 4 and the microwave receiving end 5 before the beam contacts the ground, and in order to reduce the blind area, the microwave correlation is usually arranged in a staggered mode to perform blind compensation. When the distance between the microwave correlation units 6 is less than 50m, the length of the coverage dead zone is larger relative to the detection distance, and in order to further reduce the dead zone, each microwave correlation unit 6 needs to be inclined to the ground by 5 degrees, so that the beam grounding distance can be shortened, the microwave dead zone is reduced, and the microwave coverage range is improved.
The operation is realized on the tripod 9, the tripod 9 is firstly ensured to be installed horizontally and stably, the three telescopic support columns 13 are not pulled out, then the telescopic support columns 13 at the rear part of the microwave correlation unit 6 are all pulled out, the telescopic support column locking nuts 16 are screwed, and meanwhile, the other two telescopic support columns are ensured to be immobile, so that the microwave correlation unit 6 can be detected in a state of inclining 5 degrees to the ground.
The tripod 9 comprises three telescopic support columns 13, the tail ends of which are fixed supports 17, the fixed supports 17 can freely move in a certain range and are used for adapting to the ground and stably supporting the tripod 9; the tail end of each fixed support 17 is provided with a fixing nail hole 18, the function of the fixing nail hole is that when severe weather of strong wind is met or the slope of the ground is relatively large, the tripod 9 needs to be fixedly installed relative to the ground, fixing nails can be driven into the fixing nail holes 18 for fixing, and the stability and the firmness of the tripod 9 are ensured.
All the equipment in the detection unit, including the microwave transmitting end 4, the microwave receiving end 5, the tripod 9, the low temperature resistant lithium battery 19 and the like are placed in the prefabricated sponge buffer layer 34 in the aviation safety box 20, so that the collision of the whole set of equipment in the storage and transportation processes is avoided, and the safety and reliability of the equipment are ensured.

As shown in fig. 5, the wireless alarm module 7 adopts a combined modular structure, and the master of the module includes an input interface, a power management module and an extended communication interface. According to different actual requirements on the site, wireless communication sub-modules, such as a 2.4G point-to-point wireless sub-module and a 4GLTE communication module, can be inserted into the expansion communication interface to perform multi-communication link alarm.
When the wireless communication sub-module is set as a 2.4G point-to-point wireless sub-module, as shown in fig. 6, the 2.4G point-to-point wireless sub-module can transmit an alarm signal in an environment without any wireless communication network, the alarm signal of the microwave correlation unit 6 is transmitted to the wireless remote sensing control terminal 8 serving as a receiving unit through 2.4G wireless codes, and the connection between the microwave correlation unit 6 and a control center can be quickly established (the receiving distance in an open area is more than or equal to 2000 m). 4 sets of microwave correlation units 6 adopting 2.4G point-to-point wireless sub-modules can form a closed alarm defense area, and a wireless remote sensing control terminal 8 is arranged to receive the alarm signals of the 4 sets of microwave correlation units 6 and display and output the alarm signals.
In the whole alarm link, the wireless alarm module 7 serves as an access layer, collected front-end alarm signals are forwarded through a 2.4G point-to-point wireless submodule, the wireless remote sensing control terminal 8 serves as a convergence layer to receive the alarm signals, an audible and visual alarm device is arranged to give an alarm, the alarm signals can be forwarded to a management platform (cloud server) through an alarm output port, and the alarm signals are displayed in an image-text mode through an electronic map.
When the wireless communication sub-module is set as the 4G LET communication sub-module, as shown in fig. 7, the 4G LET communication sub-module may use the existing 4G communication network to forward the alarm signal of the microwave correlation unit 6, and the 4G LET communication sub-module is bound to each microwave correlation receiving unit through a management platform (cloud server) at the rear end to form a one-to-one corresponding alarm relationship. The front end receiving unit triggers an alarm signal, the alarm signal is forwarded by the 4G LET communication submodule, and the position of the alarm signal is displayed in time by the rear end management platform system (the 4G LET communication submodule supports the GPS geographic positioning function); the alarm signal can be displayed by a PC client or a mobile client of a mobile phone, so that alarm management and processing can be more flexibly carried out.
