Summary of the invention
The present invention is for improving the intellectuality and the automaticity of low-voltage distribution equipment, by computer low-voltage distribution equipment is realized remote monitoring and provide a kind of, and networked degree height, data acquisition is accurately convenient, be easy to expansion and safeguard the intelligent remote monitoring system of the low-voltage distribution equipment of highly versatile
For achieving the above object, the invention provides a kind of intelligent remote monitoring system of low-voltage distribution equipment, it is characterized in that, this system is formed by connecting computer controlling center and low-voltage distribution equipment by multichannel terminal type signal picker and multiple-path coupler.
Described signal picker is a bus terminal.
Described coupler is the bus coupler with open communications protocol.
Described bus terminal comprises digital quantity input, lead-out terminal, analog quantity input, lead-out terminal and communication terminal.
Each member of system adopts socket connection.
Contribution of the present invention is, it has improved the intelligent degree of low-voltage distribution system greatly, make low-voltage distribution system from the signals collecting to the system, control and expand and safeguard all and under computer control, carry out automatically, thereby can be the safe and reliable power supply of low-voltage power supply and distribution system sound assurance is provided.Compare with existing low-voltage distribution equipment, the present invention has following distinguishing feature:
One,, thereby can form network with other website owing to coupler with open communications protocol;
Two, owing to adopt the terminal type data acquisition unit, therefore can according to how much the making up of the size of collection capacity, control point, and very be easy to expansion and safeguard;
Three, because bus terminal and coupler have consisted essentially of the electric parameter of national standard defined, thereby the electric elements of any manufacturer production, all can communicate with computer by bus terminal and coupler, and realization " remote control, remote measurement, remote signalling " function;
Four, can carry out program by coupler and download band PLC, thus the mutual throwing of realization double loop power supply or multiple power supplies and chain.
