Communication server

Abstract

The invention discloses a communication server. A master control module is butted with a serial communication module which is butted with a serial interface module; a power module is respectively connected with the serial interface module, the serial communication module, a display module and the master control module; the display module is connected with the master control module; and the serial interface module is provided with an interface connected with an intelligent detection device, a DCS or a PC. The server has the advantages that: the server has high automation degree; the server has good compatibility and can be interconnected with comprehensive protective devices and monitoring systems of different factories; the server has quick response, namely the master frequency of a CPU of the master control module is high, the master control module per se is provided with Ethernet interfaces, can transceive data through a network and can stably and reliably work for a long time under severe environment, and the master control module always monitors the working condition of each serial port, has low power consumption and cannot be failed due to heating after long-term operation; and the server has a simple structure and is convenient to operate and maintain.

Description

1. Technical field [0001] The communication server of the present invention relates to the technical field of data collection and communication protocol conversion, in particular to the technical field of fast data collection and protocol conversion of a low-voltage AC motor protection system. 2. Background technology [0002] At present, low-voltage AC motors are widely used with low-voltage protection and monitoring devices, which can effectively protect low-voltage motors. Some low-voltage systems include hundreds of protection and monitoring devices. In order to realize remote automation, it is necessary to quickly and accurately transmit field data to the monitoring room. And rush to the scene to deal with it. Sometimes, supervisors want to remotely control the motor, such as starting and stopping. [0003] In the past, ordinary PCs were used as the intermediate link of data collection and conversion. Due to the limited number of serial ports of the PC, it cannot mee...
