Traffic signal lamp emergency control system

Abstract

The invention provides a traffic signal lamp emergency control system. The traffic signal lamp emergency control system comprises a solar cell panel, a storage battery, a power supply management unit, a signal control device, a circuit control device and signal lamps. The solar cell panel is electrically connected with the storage battery. The storage battery supplies power to the signal control device, the circuit control device and the signal lamps through the power supply management unit. The signal control device outputs a control signal to the circuit control circuit. The circuit control device controls the states of the signal lamps. According to the invention, the solar cell panel and the storage battery are used for storing electric energy, the storage battery supplies power to the signal lamp emergency control system when the power is off, and the solar cell panel simultaneously and continuously converts light energy into electric energy and stores the electric energy to the storage battery, so that the problem that an existing emergency power supply fails to supply power for a long time is solved; in addition, the solar energy is available everywhere, nearby power supplying is realized, long-distance transmission is not needed, and the cost of a long-distance power transmission line is avoided.

Description

technical field [0001] The invention relates to the technical field of road traffic indication control, in particular to an emergency control system for traffic signal lights. Background technique [0002] The road traffic signal system and the continuous improvement of traffic regulations have played an irreplaceable positive role in regulating urban traffic behavior and maintaining urban traffic order. When there is a power outage, the traffic signal lights cannot normally indicate, resulting in traffic chaos and traffic jams, etc.; traffic at some intersections Although the signal lamp has an emergency power supply, the emergency power supply can last for a short time, and cannot be used in the case of a long-term power failure. With the widespread utilization of solar energy, how to improve the utilization rate of solar energy has become one of the focus issues of solar energy research. In today's shortage of traditional energy sources, the use of new energy and renewab...
