Description of the application of the power distribution isolator in the electrical monitoring system
With the development of communication technology and control technology, centralized monitoring and management has become an inevitable trend in the development of building intelligent management. Due to the scattered distribution of office building power distribution room, distribution box, control switch, air conditioner, etc., it is difficult to understand the safe operation status of each power distribution equipment in a timely and effective manner; the elevator power supply is far away from duty, and it is difficult for the attendant to understand in real time. Elevator power status; building security monitoring points, fire monitoring points can only achieve centralized management by forming a network. In order to realize the rapid and intelligent management of the power building, an electrical monitoring automation system for the power distribution isolator was developed.
The electrical building electrical monitoring system is a distributed control system. It takes the form of three levels and separate modules. The electrical measurement and control unit transmits the electrical state quantity of each loop collected in the field and the real-time data of the important branch to the information unit, and the information processing unit processes the received information, and uploads the command issued by the monitoring center unit and the execution center unit.
Monitoring unit: The central computer mainly plays a monitoring role and completes the man-machine dialogue. He analyzes various data transmitted by a monitoring unit, dynamically displays various areas, real-time running information, and over-limit alarms. The central computer has an operational information database that stores monitoring and operation reports for more than half a year.
Information processing unit: As an information processing unit, the PCC mainly performs data processing, information uploading and release.
Electrical measurement and control unit: mainly collects and controls the field data.
