Embodiment Construction

[0028] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:

[0029] Such as figure 1 As shown, the traffic signal control system in the prior art includes a signal machine microcontroller 1 and an AC wire 2, a current detector 5 is installed on the live wire of the AC wire 2, and the current detector 5 obtains the current value on the AC wire 2 in real time . The data output end of the current detector 5 is connected to the data input end of the signal microcontroller 1 , and the current detector 5 sends the obtained current value to the signal microcontroller 1 . A red light control switch K1, a yellow light control switch K2 and a green light control switch K3 are connected in parallel between the AC wire 2 and the light control module 3 in a traditional manner, and the red light control swi...

Abstract

The invention relates to an energy-saving control method for a traffic signal control system. Compared with the prior art, the defect that the existing traffic signal control system power reduction technology is complex or functionally imperfect is solved. The method comprises the following steps: a power adjustment demand plan is acquired; the initial current value of signal lamps is acquired; a power adjustment signal is sent out; a lamp control module receives the power adjustment signal; a signal machine microcontroller waits for a signal lamp group to cyclically run to next phase X; the current value of the signal lamps after adjustment is acquired; and the power adjustment result is verified. By triggering pulsed switching signals in a combined way, power adjustment of signal lamp equipment by signal control equipment is realized, and energy conservation and emission reduction of the signal control system are realized effectively.

Description

technical field [0001] The invention relates to the technical field of traffic signal lamps, in particular to an energy-saving control method for a traffic signal control system. Background technique [0002] The current energy-saving methods for traffic signal control systems generally adopt methods such as further reducing the power consumption of signal lights and turning off lights at night. The reduction of signal light power consumption is closely related to the development of signal light technology and cost control. Lower power consumption equipment requires more advanced technology and higher cost increases, and can only be gradually developed and applied. There are also many restrictions on the method of directly turning off part of the signal lights at night, such as turning off the arrow lights for turning left and turning right and only turning on the disc lights for going straight. Control. [0003] Therefore, on the premise of ensuring the normal operation...
