High-efficiency multifunctional power-saving automatic control system

Abstract

The invention discloses a high-efficiency multifunctional power-saving automatic control system which is mainly technically characterized by comprising an S7-200PLC, and a voltage detecting and conditioning circuit, a current monitoring and protecting circuit, a light control circuit, a voltage adjusting and control circuit, a keyboard and a display circuit connected with the S7-200PLC. The energy-saving controller include a time control mode, a light control mode, a voltage control mode and a bypass mode, and after that the keyboard and display circuit set system operation parameters, the S7-200PLC controls operation of the other circuits. The system has the advantages including independent adjustment, small size, low fault rate, high anti-interference capability and long service life, the system can be used for energy saving in routine road illumination power utilization as well as automatic control of power utilization in large plazas, enterprise factories, public places and even private apartments.

Description

technical field [0001] The invention belongs to the field of energy-saving automatic control, in particular to a high-efficiency, multi-functional, power-saving automatic control system. Background technique [0002] With the progress of society and the acceleration of the industrialization process, the use of electricity is becoming more and more extensive, and the power consumption is increasing day by day. Energy conservation and environmental protection are the general trend. Energy-saving controllers have been widely accepted by the public, and the improvement of energy-saving efficiency has also attracted people's attention. However, the scope of application of energy-saving controllers is still very limited, which obviously cannot meet the needs of society. Conventional energy-saving control of street lamps also has the traditional control method, that is, turning on the lights at dark and turning them off at dawn is a serious waste of electricity, and in the low peak...

[0002] With the progress of society and the acceleration of the industrialization process, the use of electricity is becoming more and more extensive, and the power consumption is increasing day by day. Energy conservation and environmental protection are the general trend. Energy-saving controllers have been widely accepted by the public, and the improvement of energy-saving efficiency has also attracted people's attention. However, the scope of application of energy-saving controllers is still very limited, which obviously cannot meet the needs of society.

Conventional energy-saving control of street lamps also has the traditional control method, that is, turning on the lights at dark and turning them off at dawn is a serious waste of electricity, and in the low peak period of electricity consumption in the second half of the night, due to the grid voltage quotient Left and right, the service life of the bulb is greatly reduced and disadvantages such as damage are raised, so more systematic and efficient improvements are needed
