How does the work of foreign load cells in garbage collection work? And how efficient is it? It uses a 900M tamper-evident electronic tag. The tag is installed on the front windshield of the transport vehicle. The garbage transport vehicle transports the garbage from the urban garbage transfer station. The transport vehicle then transports the garbage to the garbage disposal site for weight treatment. The garbage disposal site adopts a The platform scale weighs the transport vehicles, weighs and returns the skin, and then subtracts the weight of the entrance weight from the weight of the garbage shipped by the vehicle. Then each truck is accumulated on a daily basis, accumulated in weeks, and accumulated in the month. Its load cell system is mainly composed of the following parts:

1.Garbage transfer station antenna: It is used to write the address (garbage transfer station address information, such as: the waste transfer station of Yushan Road, Yuhu District, Changsha City) to the corresponding IC card of the transport vehicle, to the garbage source when the transport vehicle is overweight According to this, the transmission of this antenna uses GSM communication, and the computer also uses the GSM transceiver to receive or transmit data, or collect the arrival time of the vehicle.

2.Garbage transfer station 1---N: Urban area block garbage concentration point, there is N garbage dump transfer station in an urban area, garbage transport vehicles go to each garbage transfer station to transport garbage, transport to garbage disposal site, garbage into Before the station, the weight is processed first. When the weight is over, it should be judged which garbage transfer station the garbage comes from, and then entered into the computer. (Not using the sense of the ground, but reserve)

3.Voice: The broadcast of the weight and the violation of the rules when entering and exiting the pound, the system failure prompt.

4.Antenna: Used to read and write data to the IC card of an effective transport vehicle.

5.The main control board: voice / weighbridge / infrared for unified management, and then use RS485 communication to transfer data to the computer, and save data locally.

6.Video: It is used to retain the vehicle weighing environment data, and the computer captures the image through video to preserve the live environment.

7.GSM transceiver: Control the garbage transfer station antenna, or data frequency sensor acquisition. (Not using the sense of the ground, but reserve)

8.Weighbridge: The weighbridge is used to weigh the transport vehicle and weigh the so-called weight to the main control panel.

9.Ground Sense: It is to detect the entry and exit of the vehicle to detect the arrival and departure of the vehicle. There will be two senses on each platform. (Not using the sense of the ground, but reserve)

10.Infrared radiation: It is used to detect the behavior of the money of the transport vehicle. If the infrared is cut before or after the infrared, it is judged that the vehicle performs the weighing violation, and the voice or LED display prompts.

11.LED display: It is used to display the gross weight of the vehicle after violation and weighing success; it is used to display the tare and net weight after the vehicle violation and successful weighing, the system fault display and fault help.

The load cell consists of a 900M tamper-evident electronic tag. The tag is installed on the front windshield of the transport vehicle. The garbage transport vehicle transports the garbage from the urban garbage transfer station. At the same time, the site antenna writes to the IC tag card on the vehicle. Corresponding site address, the transport vehicle transports the garbage to the garbage disposal site for weighing. The garbage disposal site uses two platform scales to weigh the transport vehicles. One of the vehicles is unidirectionally weighed into the approaching vehicle. The vehicle is full of garbage. The other one weighs the vehicle in one direction (the car is unloaded), and then subtracts the weight of the entrance weight from the weight of the vehicle, and then each vehicle. Carry out daily accumulation, weekly accumulation, and monthly cumulative weight.

Arrival process: When the local sense detects that there is a vehicle going to be pounded, the system is ready to work. The front-end infrared is used to judge whether the vehicle is successfully pounded. The infrared at both ends is used to judge whether the vehicle violates the rules. The card reader then reads the contents of the IC card. Out (the content includes the vehicle number, the driver's name, which transfer station is used to load the garbage source, etc.), then take out the weight on the weighbridge, then take the picture on the camera and save the information in the computer. Write the information into the IC card and send it to the LED display to display it, then inform the main control board, use the sound method to successfully weigh the prompt, and then use the back end of the inverter sensor to detect whether the vehicle is driving out of the weighbridge. The sense is to judge the departure of the vehicle.

Outlet sub-process: When the local sense detects that there is a vehicle going to be pounded, the system is ready to work. The front-end infrared is used to judge whether the vehicle is successfully pounded. The infrared at both ends is used to judge whether the vehicle violates the rules. The card reader then reads the contents of the IC card. Out (the content includes the vehicle number, the driver's name, the weight at the time of entering the game, etc.), and then compare the weight and other information to the weight of the computer and other information. After successful, the weight on the weighbridge is removed, and the weighbridge is subtracted from the entrance weight. On the weight, save the weight and other information, then take the environment picture on the camera and save it, and then send the garbage weight into the LED display to display it, then inform the main control board, and successfully weigh it by sound. Prompt, then use the back end infrared to detect whether the vehicle is driving out of the weighbridge, and the back end senses the departure of the vehicle.

The above load cells have played a major role in the city's garbage collection work, bringing great convenience to people and greatly improving the efficiency of garbage collection!
