Embodiment 1

[0011] As shown in the figure, the campus street lamp control device described in this embodiment includes a PLC, a street lamp switch and a detection device, and the street lamp switch and the detection device are respectively connected to the output and input terminals of the PLC. The detection device is composed of a sending end 1 and a receiving end 2. The sending end 1 of the detection device and the receiving end 2 of the detection device are respectively installed and fixed on the light poles of street lamps 3 opposite to the left and right sides of the road. Install a set of detection devices at both ends of the road section where street lamp control is required, and their output signals are all input to the same PLC for processing. When no one passes the detection device, the receiving end 2 of the detection device can always receive the signal sent by the sending end 1 of the detection device. The sent signal is blocked, and the receiving end 2 of the detection devi...

Abstract

The present invention relates to a PLC-based campus street lamp control device which comprises a PLC, a street lamp switch, and a detection device. The street lamp switch and the detection device are connected to the output end and input end of the PLC. The detection device is formed by a signal sending end and a signal receiving end. When the detection device detects a pedestrian signal, the signal is inputted to the PLC, after processing, the PLC outputs an instruction to the street lamp switch to allow the street lamp switch to be switched on, and a street lamp is on. When there is no people, the detection device has no signal to be inputted into the PLC, after processing, the PLC outputs an instruction to the street lamp switch to allow the street lamp switch to be switched off, the street lamp is off, and the energy saving is realized.

Description

technical field [0001] The invention relates to a lamp control device, in particular to a PLC-based campus street lamp control device. Background technique [0002] Even if there is no one on the road at night, the existing campus street lights will all be on all night, which has the problem of wasting electric energy. Contents of the invention [0003] The purpose of the present invention is to provide a PLC-based campus street lamp control device in order to solve the deficiencies of the above-mentioned technologies, so as to solve the problem of electric energy waste in existing campus street lamps. [0004] In order to achieve the above object, the campus street lamp control device designed by the present invention includes PLC, street lamp switch and detection device, and the street lamp switch and detection device are respectively connected to the output and input ends of PLC, and the detection device is composed of a sending end and a receiving end. composition. ...
