Problems solved by technology

[0002] There are generally two ways to collect signals. One is to connect the field equipment to the input and output channels of the controller through hard contacts. This method is relatively direct, but the cost is high and the reliability is low; the other way is the field equipment. The signal is directly sent to the controller through serial communication. This method is low in cost and high in reliability, but requires high communication functions between the device and the controller.
At present, as field devices are becoming more and more intelligent, in order to save costs and improve reliability, more and more signals are not sent through hard contacts, but are required to be sent to the controller through serial communication; in addition, due to some special signals, The controller cannot collect, and it must be collected by other devices and then sent to the controller through the serial port

Abstract

The invention relates to a carrier module capable of communicating with external equipment. The module comprises a communication interface board, and an independent board card power supply module is arranged on the communication interface board; the independent board card power supply module is connected with a battery, an MCU core unit and a power supply hot plug control unit. The communication interface board is further provided with a communication interface, an external power supply interface, an input and output module interface and a rotary dial switch, and the MCU core unit is connectedwith the communication interface, the external power supply interface, the input and output module interface, the power supply hot plug control unit and the rotary dial switch. According to the invention, the hot plug power supply control technology is adopted, thereby achieving the safe hot plug of the module and guaranteeing the normal work of a system; the circuits are integrated in one circuit board, and the multi-layer PCB design is adopted, so the anti-interference performance of the device is enhanced; the structure is simple, so the device can be used in an internal expansion system and an external expansion system, and the communication conversion between the main controller and the input and output module is realized.
