Communication control interface module

Abstract

The invention relates to a communication control interface module. The communication control interface module comprises a communication interface plate, the communication interface plate is provided with an independent board power supply module, the independent board power supply module respectively connected with a batter, an MCU core unit and a power supply hot plug control unit, the communication interface plate is further provided with a communication interface, an external power supply interface, an input-output module interface and a rotary dial switch, and the MCU core unit is respectively connected with the communication interface, the external power supply interface, the input-output module interface, the power supply hot plug control unit and the rotary dial switch. According tothe communication control interface module, a hot plug power supply control technology is adopted, module safety hot plug is achieved, normal working of the system is guaranteed, circuits are integrated in one circuit board, multi-layer PCB design is adopted, the anti-interference performance of the device is enhanced, the structure is simple, the module can be used in an internal expansion systemand also can be used in an external expansion system, and communication convention of a main controller and the input-output module is achieved.

Description

technical field [0001] The invention relates to the technical field of communication devices, in particular to a communication control interface module. Background technique [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, which is low in cost and high in reliability, but requires higher 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 col...

[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
