Intelligent traffic signal lamp system

Abstract

The invention relates to an intelligent traffic signal lamp system comprising a plurality of intelligent traffic signal lamps and an external annunciator. Every intelligent traffic signal lamp comprises a control module and an embedded intelligent image analyzer, and in addition, the embedded intelligent camera is used to acquire various traffic information data. Every control module is used to convert the traffic information data into the traffic data flow, which can be identified by the external annunciator, and is used to transmit the traffic data flow to the external annunciator, and is used to process the lamp color state display information and the synchronization control instruction, which are transmitted by the external annunciator. The external annunciator is used to transmit the lamp color state display information and the synchronization control instruction to the corresponding intelligent traffic signal lamp. By adopting the intelligent traffic signal lamp system, the linkage of the own monitoring data and the external annunciator can be realized, the unidirectional passive control can be eliminated, and therefore the annunciator circuit design can be simplified, the real-time monitoring and early warning can be realized, the diversified functions can be realized, the basis can be provided for the subsequent data analysis, the remote control of a plurality of traffic signal lamps can be realized, and the wider application range can be provided.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to an intelligent traffic signal light system. Background technique [0002] Road traffic signal lights are a category of traffic safety products. They are an important tool to strengthen road traffic management, reduce traffic accidents, improve road use efficiency, and improve traffic conditions. Applicable to intersections such as crosses and T-shaped intersections, it is controlled by the front-end traffic signal controller to guide vehicles and pedestrians to pass safely and orderly. The types of signal lamps are currently dominated by LED lamps, which were originally dominated by incandescent lamps. [0003] The current road traffic signal light is only a passive execution unit, which must be controlled by the front-end traffic signal control machine to operate. All control and monitoring functions are performed by the signaling machine. There are several problems...

AI Technical Summary

Problems solved by technology

[0004] 1. External control equipment is required, otherwise it cannot work independently;

[0005] 2. The requirements for the traffic signal controller are high, first of all, the requirements for synchronization are high, otherwise there will be a phenomenon that the colors of different direction lights are not synchronized;

[0006] 3. The driving capability may require as many as dozens of signal lights; there are great challenges to the design of the stability and complexity of the signal machine

[0007] 4. The fault detection requirements of signal lamps are relatively high, and the signal control machine needs complex fault detection functions to realize fault monitoring

[0008] 5. Incompatible with other traffic equipment at intersections, such as monitoring equipment and red light equipment
