Detailed Description
The embodiments of the present application will be described below with reference to the drawings.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an electromagnetic radiation control system according to an embodiment of the present disclosure. As shown, the system in the embodiment of the present application includes a user device and a user. The user equipment may be any equipment with wireless transceiving function, and may refer to equipment providing voice and/or data connection to a user, may be connected to a computing device such as a laptop computer or desktop computer, or may be a stand-alone device such as a Personal Digital Assistant (PDA). A user equipment may also be called a system, subscriber unit, subscriber station, mobile, remote station, access point, remote terminal, access terminal, user agent, or user device. The user equipment may be a device generating (5-generation, 5G) millimeter waves of a fifth generation mobile communication technology, such as a notebook, a router, a watch, and the like. A ranging sensor may be included in the user equipment, and a separation distance between the user and the user equipment is measured by the ranging sensor. Based on the system, the embodiment of the application provides the following solution.
Referring to fig. 2, fig. 2 is a schematic flow chart of an electromagnetic radiation control method provided in an embodiment of the present application, where the method includes, but is not limited to, the following steps:
s201, acquiring the spacing distance between the user equipment and the user.
In specific implementation, the distance measuring sensor may include a laser distance measuring sensor, an infrared distance measuring sensor, an ultrasonic distance measuring sensor, a millimeter wave distance measuring sensor, and the like, and may measure the distance between the user equipment and the user through the laser distance measuring sensor, the infrared distance measuring sensor, the ultrasonic distance measuring sensor, or the millimeter wave distance measuring sensor. The ranging sensor can be arranged inside the user equipment, and the ranging sensor can also be placed on the user equipment for use. For example, a laser ranging sensor arranged in the user equipment can be used for transmitting a laser signal to the user and recording a time point of transmitting the laser signal, the laser signal returns to the laser ranging sensor after being reflected by a human body, the time point of receiving the laser signal is recorded at the moment, the transmission time length of the laser signal is determined according to the time point of transmitting the laser signal and the time point of receiving the laser signal, and then the spacing distance between the user equipment and the user is determined according to the transmission time length. Alternatively, the separation distance between the user equipment and the user may be measured by using the principle that the infrared ranging sensor emits an infrared signal and the intensity of the reflected infrared signal received is different due to the difference in separation distance. The separation distance between the user equipment and the user can also be measured by other methods, which are not described herein.
The influence degree of the electromagnetic radiation on the user is related to the spacing distance between the user equipment and the user, the closer the spacing distance is, the greater the influence degree of the electromagnetic radiation on the user is, the farther the spacing distance is, the smaller the influence degree of the electromagnetic radiation on the user is, and when the spacing distance exceeds the preset distance range, the influence degree of the electromagnetic radiation on the user is almost 0. The separation distance between the user equipment and the user may be measured by a ranging sensor within a preset distance range. The predetermined distance range may be a distance, such as 20cm, at which the electromagnetic radiation has an effect on the user. Within the preset distance range, the electromagnetic radiation generated by the millimeter waves emitted by the user equipment needs to be controlled within the range of the maximum allowable radiation amount.
Optionally, the separation distance between the ue and the user may be measured according to a preset period, and the separation distance measured each time is reported to a core processor of the ue for processing. The preset period may be 1 second or 2 seconds, etc.
Optionally, a plurality of measurement distances between the user equipment and the user obtained through a plurality of measurements may be obtained; taking an average of the plurality of measurement distances as the separation distance.
S202, according to the spacing distance, the equivalent access radiation power of the millimeter waves emitted by the user equipment is adjusted, so that the electromagnetic radiation generated by the emitted millimeter waves meets the maximum allowable radiation quantity. The millimeter wave is an electromagnetic wave with the wavelength of 1-10 mm, and has the characteristics of high bandwidth and narrow beam. The equivalent access radiation power is the radiation power in a certain specified direction, and is ideally equal to the transmission power of the power amplifier multiplied by the gain of the antenna.
In the specific implementation, on the premise that the electromagnetic radiation generated by the transmitted millimeter waves meets the maximum allowable radiation quantity, when the spacing distance is increased, the equivalent access radiation power of the millimeter waves transmitted by the user equipment can be improved, so that the transmission efficiency of the millimeter waves is improved. When the spacing distance is reduced, the equivalent access radiation power of the millimeter waves transmitted by the user equipment can be reduced, and the user is protected from the influence of electromagnetic radiation.
Further, a power value corresponding to the separation distance may be searched from a preset target calibration table, where the target calibration table includes a corresponding relationship between the separation distance and the power value; and adjusting the equivalent access radiation power of the millimeter waves transmitted by the user equipment to the power value, thereby ensuring that the electromagnetic radiation generated by the user equipment does not influence the user at the spacing distance. For example, as shown in fig. 3, fig. 3 is a schematic diagram of a calibration table provided in an embodiment of the present application, where the calibration table is a calibration table for EIRP and separation distance that meet the maximum allowable radiation requirement. When the distance between the user and the user equipment is D-0, the equivalent access radiation power of the millimeter waves emitted by the user equipment can be adjusted to EIRP-1, and the electromagnetic radiation generated by the millimeter waves emitted by the user equipment in the range of D-0 can not influence the user. When the distance between the user and the user equipment is D-3, the equivalent access radiation power of the millimeter waves emitted by the user equipment can be adjusted to EIRP-3, and the electromagnetic radiation generated by the millimeter waves emitted by the user equipment within the range of D-3 can not influence the user.
In addition, before the adjustment of the equivalent lead-to radiation power of the millimeter wave transmitted by the user equipment, the calibration table of the EIRP and the separation distance may be configured in advance for use in adjusting the equivalent lead-to radiation power. The method specifically comprises the following steps: the method comprises the steps of placing ranging sensors on the front side, the back side and the frame of the user equipment, completely covering a radiation space of an antenna used by the user equipment for transmitting millimeter waves, measuring the distance between the user equipment and a user through the ranging sensors, measuring the current electromagnetic radiation size, and recording the equivalent access radiation power of the millimeter waves transmitted by the user equipment at the moment when the electromagnetic radiation size meets the maximum allowable radiation quantity. Then, the distance between the user equipment and the user is changed, and a plurality of tests are carried out according to the method, so that the calibration table of the EIRP and the spacing distance can be generated.
Optionally, since an antenna used for transmitting the millimeter waves in the 5G application may be changed according to a change of a network environment, electromagnetic radiation generated by the antenna is different. Therefore, the calibration table corresponding to each antenna in all antennas of the user terminal can be configured in advance. In a network environment of practical application, a received signal strength of each antenna in a plurality of antennas of the user equipment may be obtained first; according to the received signal strength, determining an antenna used by the user equipment to transmit the millimeter wave, for example, an antenna with the highest received signal strength may be used as the antenna used to transmit the millimeter wave, or an antenna with the received signal strength greater than a preset threshold may be used as the antenna used to transmit the millimeter wave. And then selecting the target calibration table from a plurality of preset calibration tables according to the antenna used for transmitting the millimeter waves, thereby realizing the accuracy of adjusting the equivalent access to the radiation power.
In the embodiment of the application, firstly, the spacing distance between user equipment and a user is obtained; and then according to the spacing distance, adjusting the equivalent access radiation power of the millimeter waves transmitted by the user equipment, so that the electromagnetic radiation generated by the transmitted millimeter waves meets the maximum allowable radiation quantity. The equivalent access radiation power of the transmitted millimeter waves is adjusted according to different spacing distances between the user equipment and the user, so that the transmission power and the transmission efficiency of the millimeter waves are improved on the premise of guaranteeing the safety of the user.
