[0034] An AC power source 110 is electrically connected to an AC / DC (alternating current / direct current) power source 120;

[0035] AC / DC power supply 120 is electrically connected to DC / DC (synchronous buck) power supply 130;

[0036] A DC / DC power supply 130 is electrically connected to an LDO (linear regulator) power supply 140 ;

[0037] An LDO power supply 140 is electrically connected to a processing and application module 150 ;

[0038] The processing and application module 150 includes:

[0039] MCU (Micro Controller Unit) system 151 is in communication with FLASH 152;

[0040] FLASH152, communicates with the watchdog 153 module;

[0041] The watchdog module 153 is in communication with the LoRa module 154;

[0042] LORA (Long Range, linear frequency modulation spread spectrum modulation technology) module 154, communicating with RS232 interface 155;

[0043] RS232 interface 155 is communicatively connected to RS485 interface 156;

[0044] The RS485 interface 156 is electrically connected to the LED light 157 .

[0045] It is understandable that the host-side MCU chip GD32F407 uses the SPI (Serial Peripheral Interface, synchronous serial transmission specification) interface for FLASH152 expansion, and uses 32MB of DATA FLASH152 for data and parameter storage. Each data is 4k in size, and 1500 records are about 6MB, which meets the historical data storage requirements.

[0046] It can be further understood that the host has no less than 1 RS485 interface 156 interface, no less than 1 RS232 interface 155 interface, no less than 2 4-20mA analog measurement interfaces, and no less than 2 encoder measurement interfaces; the slave has no less than 1 weight sensor interface; the host side MCU chip GD32F407 expands one RS485 interface 156 interface through the UART interface, expands one RS232 interface 155 interface through the UART interface, collects two 4-20mA analog quantities through the chip's internal ADC (Analog-to-Digital Converter), and collects two encoder measurement signals through the chip's TIMER function pin.

[0047] The slave-side MCU chip GD32F407 collects the analog small signal input by the weight sensor through the SPI interface via the ADC chip to achieve weight acquisition.

[0052] In some embodiments of the present invention, the system further includes:

[0053] 4G (Generation) module, the 4G module is electrically connected to the LDO power supply 140 .

[0054] As you can understand, the 4G interface supports communication with the server and supports data transmission between the host and slave devices via LoRa (linear frequency modulation spread spectrum modulation technology). The host-side MCU chip GD32F407 completes information exchange with the master server via the serial port via the 4G module, and the communication protocol supports HTTP (Hyper Text Transfer Protocol). The MCU completes information exchange with the slave device via the serial port via the LoRa module 154, following the MODBUS protocol.

[0056] In some embodiments of the present invention, the system further includes:

[0057] An RTC backup battery is electrically connected to the processing and application module 150 .

[0058] It is understandable that the host-side MCU chip GD32F407 uses the I2C interface to expand the RTC circuit for local timekeeping, and uses a CR1220 battery as the RTC (Real-Time Clock) backup power supply for power-off timekeeping.

[0059] In some embodiments of the present invention, the processing and application module 150 includes:

[0060] RTC, the RTC is electrically connected to the LED light 157.

[0061] In some embodiments of the present invention, the RTC is further electrically connected to an RTC backup battery.

[0062] In some embodiments of the present invention, the supply voltage of the RTC is 3.0V.

[0063] It is understandable that both the host and slave power modules use the Golden Sun power module LD30-26B24R2, which meets the wide input voltage range of 176-528VAC / 248-746VDC and can operate normally when connected to any two-wire power supply in a three-phase four-wire power supply system. The module has functions such as output short circuit, overcurrent, and overvoltage protection.
