Power monitoring background should have the function
In general, the microcomputer protection has a communication interface, the beginning is 485 communication interface, through the shielded twisted pair to communicate, and then gradually developed into a double 485 communication.485 Communication in general anti-interference and communication distance, but the rate is not very high, in general baud rate is 9600.Later introduced Ethernet communication, compared with 485 communication, Ethernet communication rate is fast, reliability is also relatively high.In most cases, the network is to connect the microcomputer protection to the communication management machine, and then the communication management machine is connected with the background to complete the communication function.The general structure is as follows:
Then the full background should have the function
(I) The station requires communication equipment to do communication, and the background monitoring can fully display the corresponding data.In addition to microcomputer protection, there are DC screen, network instrument, watt-hour meter, low current ground line selection, etc.And make the corresponding picture.
(2) Real-time changes of data telemetry, remote signaling and remote pulse.Fast response rate of remote control and remote control, that is to say, the message refresh is relatively fast, compound the actual requirements of the field.
(3), the background system and microcomputer background monitoring software compatible, to choose the appropriate system according to the background software, the general field use of the system is Windows 2000, Windows XP, Win7, Unix, Linux.
(4) Installation of database, database and background monitoring system reliable compatibility, stable operation.Generally, it is SQLServer, Mysql and so on to ensure the stable operation of historical database.Make reports and historical curves according to the requirements of station operation and maintenance personnel.
(5) If there are two hosts in the background, the general configuration is the main and standby machines.
