The present application provides a planer circuit control device, comprising: a planer PLC control circuit module, a communication module and a display module, the planer PLC control circuit module is provided with a first data interaction interface, the communication module is provided with a second data interaction interface and a display communication interface, the planer PLC control circuit module is connected with the second data interaction interface of the communication module through the first data interaction interface; the communication module is connected with the display module through the display communication interface.

[0021] In the present embodiment, the first data interaction interface and the second data interaction interface are preferably RS485 interfaces, the display communication interface is preferably a LAN interface, the planer PLC control circuit module establishes an RS485 connection with the second data interaction interface of the communication module through the first data interaction interface; the display module is provided with a LAN interface, the communication module establishes a connection between the display communication interface and the LAN interface of the display module through a network cable; the display module is a DOP-10WS industrial display screen, and the communication module is an AS324MT module.

[0022] The present application provides a planer circuit control device equipped with a planer PLC control circuit module that monitors the various operating states and operating parameters of the planer. When the planer PLC control circuit module detects a change in the planer's operating state or a need to update data, it packages the data into a data frame that complies with the RS485 communication protocol and sends the data frame to the second data interaction interface of the communication module via the first data interaction interface. After receiving the data frame from the PLC via the second data interaction interface, the communication module parses and verifies it and, based on preset rules or trigger conditions (such as timing, data changes, etc.), sends the processed data frame to the display module. After receiving the data frame, the display module parses and verifies it and, through the configuration software or application within the display module, updates the display elements (such as numerical display, charts, indicator lights, etc.) on the interface based on the received data, reflecting the planer's operating state in real time.

[0023] Of course, in other embodiments, according to actual data transmission requirements, the first data interaction interface, the second data interaction interface and the display communication interface can also be adjusted to RS232 interface and RJ45 interface, etc.; according to actual display requirements, the display module can also select other models of industrial display screens.

[0024] The planer circuit control device provided in this application adds a communication module alongside the existing PLC control circuit module. This module effectively communicates with the PLC control circuit module, reading the planer PLC device's operating data in real time and displaying this data on a touch screen, allowing the operator to intuitively understand the device's operating status in real time. This effectively resolves issues with the PLC control circuit module's status monitoring and improves the device's reliability and operating efficiency.

[0025] See also Figure 2 , Figure 2 This is a schematic diagram of another embodiment of a planer circuit control device according to the present application. In one embodiment, the planer circuit control device provided by the present application further includes a serial port service module and a data server. The serial port service module is provided with a first serial port, a second serial port, and a third serial port. The communication module further includes a serial port connection interface. The serial port service module is connected to the serial port connection interface of the communication module via the first serial port, to the display module via the second serial port, and to the data server via the third serial port.

[0026] The serial port service module is a industrial routing gateway, model USR-G809; the first serial port is a RS485 interface, the second serial port is a LAN interface, the third serial port is a RJ45 interface, and the serial port connection interface is a RS485 interface. The serial port service module establishes a RS485 communication connection with the serial port connection interface of the communication module through the first serial port, connects the second serial port and the LAN interface of the display module through a network cable, and connects the third serial port and the data server through a network cable.

[0027] After the PLC control circuit module sends the data frame to the communication module, the communication module transmits the read data frame to the first serial port of the serial port service module through the display communication interface. After the serial port service module receives the data frame, the data frame conforming to the RS485 communication protocol is parsed, the data therein is extracted, and the data is repackaged into a data packet according to the Ethernet protocol. The serial port service module transmits the data packet to the LAN1 interface of the display module through the second serial port. After the display module receives the data frame, the data frame is parsed and verified, and the display elements (such as numerical display, chart, indicator light, etc.) on the interface are updated according to the received data through the configuration software or application program inside the display module, to reflect the working state of the planer in real time.

[0028] Meanwhile, the serial port service module transmits the data packet to the data server through the third serial port. In the transmission process, the firewall needs to perform security check on the data packet, such as checking the source, destination, and content of the data packet, to ensure the safety and compliance of the data. If the data passes the firewall verification, the data server stores the data in the data packet into a designated database or file. If the data fails the verification, error handling is performed, such as recording error logs and sending alarm information.
