Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.
The description of the marking method is included in the description of the use of the device of the invention, i.e. the marker.
The volume size of marker is 150 (length) x120 (width) x72 (height) mm, adopts standard square body appearance, and the metal casing structure has three external interface: the antenna connector and the 4-core socket used by the communication module are used for power supply and serial communication, the external camera interface is provided with no other part connected with the outside, the 5V safe voltage power supply supplies power, the SD card is arranged, and the SD card is sealed, dustproof and extremely low in standby power consumption. The marking side of the laser output type marker is a plane transparent acrylic plate or a glass plate at the position 50mm away from the movement plane of the laser. And a metal door with automatic opening and closing capability is arranged outside the door. The metal door is externally provided with a grid-shaped metal frame, so that the printing head can be applied to the printed object during marking, and the printed object can be basically kept flat. The 4-core socket is provided with two data communication lines besides a power supply positive wire and a power supply negative wire, and can be communicated with equipment outside the marker body in a wired communication mode.
The marker is also provided with an external electric component, needs to be arranged outside the marker, and is a steering engine movement mechanism used for pressing the garbage bag to the printing side of the marker so as to ensure that the printing surface keeps a plane posture. The steering engine mechanism can be in communication cooperation with the marking device.
The external camera is used for taking pictures of the whole garbage bag, large garbage and bulk garbage.
In both cases the marking machine can be driven to start marking.
Firstly, an instruction from a serial port or a wireless communication interface is received, and marking is carried out according to characters in the instruction.
Secondly, according to the sensing of the illumination detection module, the condition is suitable for the use scene in the dustbin, when the illumination detection module senses that the illumination is changed from bright to dark, marking is started, and the printed characters are characters obtained by adding 1 to the last printed character value. The original character of the default initial configuration is a character with a value of 0.
With which drive scheme, configuration can be performed with instructions. No matter which kind of beat mark drive takes place, all can be before printing the condition that the infrared proximity sensor of diffuse reflection type, human body are close sensing module and external camera judge the object, the mark is beaten to the restart.
After marking is started, a built-in camera analyzes the marking effect in real time, the analysis result is used as a feedback signal to adjust the power and the irradiation time of a laser printing head or the depth of a mechanical needle printing head in real time to determine the size of a dot matrix (the size of the dot matrix is mainly used for preventing liquid leakage by utilizing tension, if the dot matrix is too small, a plurality of lines of dot matrixes can form strokes for convenient identification, the distance among small dots on the strokes is larger at the edge, the core position is smaller so as to prevent the whole dot or line or even the whole word from falling off from a bag), and other parameters, so that garbage bags with different colors, thicknesses and different garbage can be subjected to permanent marking easy identification; the code printing is performed by using dense small holes, so that liquid leakage is prevented conveniently, and the specific dot matrix size and the distance between dots are selected to the maximum extent on the premise of leakage prevention. In the marking effect analysis process, a 'middle' word is printed at the tail end, namely the right end, of the printing area, definition analysis is carried out on each point in the printing process of the word until proper parameters are found before the word is printed, and then actual marks are printed according to the parameters. After the code is printed, the picture is taken for storage, so that the picture can be confirmed when part of the printed code is identified due to pollution, damage and the like. The invention is provided with a specially designed mobile phone APP for code scanning identification or naked eye identification; sensing the existence of the garbage bags by using a diffuse reflection type infrared proximity sensor, namely outputting an action to perform coding marking only after the garbage bags approach; the human body approaching sensor is used for protecting the approaching human body, namely if the human body approaches, the action is not output.
In order to improve marking speed as much as possible, enhance identifiability as much as possible and ensure that the codes can effectively identify each generation of garbage, the coding mode utilizes 80 characters in 0-9, lower case letters a-Z (minus the lower case i and l), upper case letters A-Z and 20 visible ASCII characters $% & () + "-/< = > @ { [ ] } \\/^ in an ASCII code table to generate 80-system codes, and simple Chinese characters and other Arabic letters except the numbers can be added to form higher-system codes. Thus, at most 6 characters (2621.44 billion to the power of 6 of 80) can be used to uniquely encode each bag of litter for at least a month in the geographic region of any country around the world, and the litter must have been sorted for one month. For processing in a large city domain, the 4-bit character can meet the requirement. The garbage bag is not marked in a dot matrix graphic mode similar to a two-dimensional code, so that sorting personnel can recognize the garbage bag by naked eyes when the garbage bag is dirty and cannot recognize the garbage bag by a code scanning mode. But a painted two-dimensional code may also be printed.
