Terminals and terminal building system based on electric load management intelligent recognition system

Abstract

The invention discloses terminals and a terminal building system based on an electric load management intelligent recognition system. The electric load management intelligent recognition system comprises a frequency selection circuit; the frequency selection circuit comprises an active band pass filter formed by an integrated operational amplifier and an RC network; the terminals comprise a power interface, a current sensor, a voltage sensor ASSS, an A / D conversion module, a communication module, a relay control module and output jacks; the terminal building system comprises a server, a communication network, multiple terminal electric devices, multiple electric load management intelligent recognition system terminals, and multiple concentrator. Through the above technical scheme, through carriers of the frequency selection circuit, terminals formed by the recognition system can be recognized, and the terminal building system can realize power supply, power control, power limit, meter reading and charging; and electric detection and measurement can be carried out by the multiple terminal electric devices, timely alarming and forced power cutoff can be carried out, records can be exchanged with the server, and detection, control and safety are improved.

Description

Technical field [0001] The invention discloses a terminal and a terminal construction system based on an intelligent identification system for electric load management. Background technique [0002] At present, the safety of electricity consumption in the densely-living environment such as student apartments and dormitories of colleges and universities has gradually received great attention from managers. In order to effectively prevent or eliminate fire hazards, electric heating loads with high power or potential safety hazards need to be controlled, such as electric stoves, fast heating, electric irons, etc., intelligent measurement and control technology can be effectively used for the detection of such vicious loads, so Has become more and more widely used. At present, intelligent measurement and control terminals are usually only used to identify purely resistive loads in linear loads (such as electric heaters, electric stoves, electric blankets, etc.). Nowadays, the more ...

AI Technical Summary

Problems solved by technology

However, this kind of power measurement and control system generally has the following limitations: (1) it cannot effectively identify the nature of the resistive load (such as electrical appliances that are allowed or not allowed to be used); The inductive load air conditioner and capacitive load cannot be detected and controlled; (3) Uninterrupted and unlimited power time control in toilets, aisles and other public emergency lighting spaces in densely populated power consumption environments (but metered electricity charges) can not achieve

(4) It cannot effectively detect the faults of common electrical loads and give an alarm
