Abstract

The invention provides a communication module circuit, which comprises an RS232 communication circuit, an RS485 communication circuit, an RJ45 network interface circuit, a power conversion circuit andan SD / TF card interface circuit, wherein the RS232 communication circuit comprises an integrated chip U2 and a display screen pin P3; the RS485 communication circuit comprises an integrated chip tU1and an integrated chip tU2; the RJ45 network interface circuit comprises an integrated chip U1, a crystal oscillator Y1 and a network isolation transformer N1; the power conversion circuit comprises acurrent conversion chip U3 and a power supply isolation chip B1; and the SD / TF card interface circuit comprises a main control chip U9 and a card strip interface TF1. According to the communication module circuit, through the SD / TF card interface circuit and various communication state indication circuits, such as the RS232 communication circuit, the RS485 communication circuit, the RJ45 networkinterface circuit and the power conversion circuit, the overall size of the module is small, and various interfaces are provided.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication module circuit. Background technique [0002] The high-vacuum multi-cavity multi-channel oven used in the production of lithium batteries needs to control tens of hundreds of heating plates at the same time, and also send the temperature data to the LCD liquid crystal display for display. Vacuum, nitrogen filling, etc. control, as well as control command reception and data upload not from the host computer. Therefore, there are many control points required, a large amount of communication data, and multiple protocols. However, the traditional PLC is quite cumbersome to implement these functions, requiring many IO expansion modules, and the communication interface is generally not enough, resulting in complicated wiring, high difficulty, and low production efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a ...
