[0037] The weight data of the weighing unit 20 cannot be modified, ensuring the confidentiality and authenticity of the data and reducing the possibility of forgery; the system is easy to operate and is similar to the use of ordinary electronic scales, with stable functions, long life and no need for frequent maintenance; it realizes fast automatic weighing and data recording, improves weighing efficiency, and reduces manual data management and labor costs; by adding a camera 40 and an automatic upload function, all weighed solid waste will be automatically recorded to avoid manual intervention and ensure the integrity and traceability of the data.

[0038] In this embodiment, the weighing unit 20 is an electronic scale, including a table for placing solid waste, the table size is 300mmX400mm, and the solid waste placed on the table can record the weight data and transmit it to the control unit 10, the weighing range is 0.00~150.00KG, accurate to two decimal places.

[0039] In one embodiment, see Figure 2 The above-mentioned control unit 10 includes a control chip U6, and the control chip U6 is an STM32 series chip.

[0040] In one embodiment, see Figure 3 The weighing unit 20 includes a sensor chip U1 and a bridge sensor R6 , the sensor chip U1 is connected to the bridge sensor R6 , and the sensor chip U1 is connected to the control chip U6 .

[0041] Specifically, the sensor chip U1 is a weight transmitter controller, which uses a high-speed 24-bit ΔA / D converter and a 16-bit D / A converter, and all 4 interfaces are photoelectrically isolated. It has an embedded anti-EMC interference circuit, strong anti-electromagnetic interference capability, stable data, suitable for industrial field applications, supports a series of host computer communication operations, records the data transmitted by the bridge sensor R6, analyzes and proofreads, and transmits the data to the control unit 10.

[0046] In one embodiment, see Figure 8 The control chip U6, weighing unit 20, 232 communication module, 485 communication module, network interface and power supply unit are respectively installed on the circuit board. The circuit board is also connected with a function selection button SW1, which is a 10-bit red dial switch.

[0047] The STM32 processor is used as the control unit 10, with isolated 485 and 232 communication interfaces, and ESD, overvoltage, and overcurrent protection functions to avoid the impact of field signals on the communication interface. The communication interfaces can be used simultaneously, with a network interface, and can transmit data to the server when connected to the Internet.

As a result, the PLC control system began to malfunction after a few months of operation and needed to be repaired before it could be used normally. This easily led to data storage loss and the inability to store data during maintenance. In addition, the PLC control system was large in size and occupied a large space, making it impossible for the space-constrained electrical control cabinet to accommodate more electrical components. Therefore, this circuit board was used. After spraying the three-proof glue, it can be used stably for a long time. The circuit board is small in size, so more space can be reserved for protective electrical components and the size of the electrical cabinet can be reduced.

[0052] In the system of this embodiment, on the touch screen 30, the user does not need to log in to the account. Before weighing, the user needs to ensure that the equipment is operating normally, and then weigh the solid waste without peeling or peeling according to the type of solid waste, and can view the local history records. On the web page, the user needs to enter the URL, and after logging in, he can view the detailed information and real-time monitoring data of each site, as well as the weighing data reports of various types of solid waste. On the terminal 50, the user needs to download the corresponding client and enter the correct account password to log in. He can view the list of each site and enter the detailed data interface, as well as view the site historical data and real-time video information.

[0053] In summary, the type of solid waste is selected through the touch screen 30 and uploaded to the control unit 10, and the weighing unit 20 automatically completes the weighing process, and data recording and display are also automatically completed. This can reduce manual intervention, improve operating efficiency, and reduce labor costs.

[0054] The weight data of the weighing unit 20 cannot be modified, ensuring the confidentiality and authenticity of the data and reducing the possibility of forgery. At the same time, the system automatically saves all weighing data and compiles statistics by month, quarter and year to form a table, so that managers can view the management status and statistical data of solid waste at any time.

[0055] The system is equipped with 40 cameras to record the operation of the staff and the real-time status of the storage area. All weighed solid waste will be automatically recorded to avoid manual intervention and ensure the integrity and traceability of the data.

[0056] Adopt high-quality control chip and sensor chip, with stable function and long life. The system is easy to operate, similar to the use of ordinary electronic scales, and does not require frequent maintenance.

[0057] The system has multiple communication interfaces, including 232 communication module, 485 communication module and network interface, which can transmit and connect data with touch screen 30, MES system and server. In this way, real-time display, data storage and remote monitoring can be realized.

[0058] The outer surface of the circuit board is coated with three-proof glue to prevent corrosion and moisture, extending the service life of the system. The circuit board is small in size, which can save space, leave more space for protective electrical components, and reduce the size of the electrical cabinet.

[0059] In summary, the solid waste intelligent weighing system achieves many benefits including automated operation, data accuracy and confidentiality, image recording and traceability, system stability and long life, data transmission and connectivity, as well as circuit board protection and space saving.
