Tunnel lighting control system based on single-chip microcomputer

Abstract

The invention discloses a tunnel lighting control system based on a single-chip microcomputer, and mainly solves the problems of complex circuit, single function and high equipment maintenance quantity in the prior art. The control system comprises the single-chip microcomputer having a timing function, a voltage stabilized power supply which is connected with the power supply input end VCC of the single-chip microcomputer, a tunnel lamp control circuit which is connected with the parallel I / O ports P1.1-P1.7 of the single-chip microcomputer, a power supply monitoring circuit which is connected with the parallel I / O port P0.1 of the single-chip microcomputer, an emergency control circuit which is connected with the parallel I / O port P0.2 of the single-chip microcomputer, a sound-light warning circuit which is connected with the parallel I / O port P0.3 of the single-chip microcomputer and a remote monitoring module which is connected with the parallel I / O port P0.4 of the single-chip microcomputer. With application of the scheme, the tunnel lighting control system based on the single-chip microcomputer has the advantages of being simple in structure, low in input cost, low in maintenance quantity, long in the service life and economical in electric energy so as to has high popularization and application value in the field of tunnel lighting.

Description

technical field [0001] The invention relates to the field of tunnel lighting, in particular to a tunnel lighting control system based on a single-chip microcomputer. Background technique [0002] With the rapid development of the road industry, in order to ensure smoother roads, more and more tunnels have been built according to the terrain conditions of the construction. Tunnel lighting is an important part of it, and energy-saving control of tunnel lighting has become the subject of exploration. At present, there are various control methods for tunnel lighting, but the components used are complicated, the control circuit is complex, the functions are relatively single, and the maintenance of equipment is large.
