[0002] Network relays are key underlying devices at the intersection of industrial automation and the Internet of Things (IoT), primarily used in smart grids, building automation, and remote equipment control. As a digital upgrade of traditional relays, they integrate electrical isolation and network control through HTTP+MQTT protocols and communication methods such as Wi-Fi, 4G, and Ethernet, forming the "last mile" execution terminal node in the Industry 4.0 system.

The method or technical solution for analyzing the output data of the data processing module through an IoT data platform and issuing control commands based on different data in this embodiment is existing well-known technology and will not be elaborated further here.

[0040] The digital input module is used to acquire the digital status signal of the relay and transmit it to the data processing module; specifically, such as... Figure 7 As shown, the preferred chip used in the digital input module of this embodiment is the PCA9557PW. The main function of the PCA9557PW chip is as an I / O expander, communicating with the main controller via the I2C bus to expand the number of I / O ports of the microcontroller.

The other end of the eleventh resistor R411 is connected to the VCC_3.3V terminal and to pin 23 of the processing chip U14. Pin 16 of the adapter chip U4 is connected to one end of the twentieth capacitor C6, one end of the twentieth capacitor C7, and the source of the first MOSFET Q1. The first MOSFET Q1 is preferably a BSS138. The other end of the twentieth capacitor C6 and the other end of the twentieth capacitor C7 are grounded. The drain of the first MOSFET Q1 is connected to the VCC_3.3V terminal. The gate of the first MOSFET Q1 is connected to one end of the ninth resistor R5. The other end of the ninth resistor R5 is connected to one end of the tenth resistor R920 to form a connection point, which is connected to the TYPE-C interface power supply terminal. The other end of the tenth resistor R920 is grounded.

[0043] In this embodiment, the adapter chip U4 uses CH340C. The working principle of CH340C chip is as follows: it can receive commands sent by the host through the USB bus, convert them into corresponding serial port signals, and then transmit the data to the target device; conversely, the data stream of the target device is converted into USB protocol format and then transmitted back to the host. In this way, effective bridging between two different communication protocols is realized.

[0044] like Figure 6 As shown, the power supply module supplies power to the main relay module, and the data processing module acquires the relay control signal based on the multimodal sensor signal and the switch status signal, and transmits the relay control signal to the relay output module, such as... Figure 5As shown, the relay output module is used to control the operation of preset actuators via relay control signals. In this embodiment, the power supply module preferably uses the SGM61230 chip. The SGM61230 is a synchronous buck converter, mainly used to convert higher input voltages into lower, stable output voltages. Specifically, the SGM61230 is a synchronous buck converter launched by SG Microelectronics, featuring a wide input voltage range of 4.5V to 28V and a continuous output current capability of 3A. It integrates two switching MOSFETs, employs internal loop compensation and a 5ms soft-start design to reduce the number of external components. The chip also features a frequency hopping mode, maximizing efficiency and reducing power loss under light loads. Furthermore, the SGM61230 has overcurrent and overvoltage protection functions, and its operating temperature range is -40℃ to +125℃, making it suitable for various industrial and agricultural electronic products. In this embodiment, the relay output module preferably uses the 74HC574PW chip; the main function of the 74HC574PW chip is to store and output data. The 74HC574PW chip has a storage function, enabling it to store input data in internal registers for subsequent processing. Based on the stored data, the 74HC574PW chip can output the stored data in parallel or serial mode. Furthermore, the 74HC574PW chip controls input and output data via control pins, such as setting input enable and output enable. It can also output multiple input data in parallel, improving data processing efficiency. In this embodiment, the 74HC574PW chip is used in the relay output module as an 8-bit tri-state D flip-flop to control the relay's latching and output. The specific function of the 74HC574PW chip in the relay output module is as follows:

[0045] (1) Data storage: The 74HC574PW chip can store 8 bits of binary data, which can be used to control the on / off state of the relay.

[0046] (2) Output control: The output of the relay can be controlled by controlling the output control terminal (pin 1) of the control chip. When pin 1 is low, the chip enables the output; when pin 1 is high, the chip output is in a high impedance state.

[0047] (3) Clock signal: The chip's clock signal (pin 11) is used to trigger data latching. On the rising edge of the clock signal, the data at the input terminal is latched into the 8 flip-flops.

[0048] In summary, the 74HC574PW chip in the relay output module serves multiple functions, including data storage, output control, and clock signal triggering. These functions enable precise control and output of the relay, thereby controlling the operation of preset actuators. For example: Example 1: A customer in Northern Industry can use network relays to monitor workshop temperature in real time. When the temperature is below a certain level, the heating fan is turned on; when the temperature is above a certain level, the heating fan is turned off, achieving energy savings. Example 2: An agricultural customer, where it's inconvenient to lay network cables between greenhouses, uses 4G network relays. These relays can monitor light intensity and soil temperature and humidity in real time, automatically controlling the opening and closing of greenhouse curtains based on different light indices, and automatically controlling the opening and closing of water pumps based on different soil moisture levels.

Simultaneously, based on the preset MQTT and HTTP protocols, it achieves bidirectional reliable transmission of data or signals, solving the problem that traditional single Ethernet or RS485 solutions can only communicate via wired connections, and that in environments without communication lines, it is necessary to re-lay communication network cables.
