Embodiment Construction

[0042] figure 1 An example shows a schematic diagram of a system architecture to which the embodiments of the present application are applicable in a specific implementation scenario, such as figure 1 As shown, the system architecture applicable to the embodiments of the present application includes a control device and N signal lights, the N signal lights are connected to the control device through a communication network, and N is an integer greater than 0. The communication network shown may be a wide area network, a local area network, or the like.

[0043] Each signal light can be connected to the network through an Ethernet port, General Packet RadioService (GPRS), Narrow Band Internet of Things (NB-IoT), etc., and communicate with the control device. communication. The control device sends network commands to control the on-off of the signal lights and other operations.

[0044] figure 1 In the system shown, each signal light can also detect the real-time light colo...

Abstract

The embodiment of the application provides a traffic signal lamp control method and system; the traffic signal lamp control system can be applied to various of application scenes, and has the following features: 1, the traffic signal lamp can be connected to the network via Ethernet port, GPRS, and NB-IoT modes, and communicates with control equipment; 2, the control equipment gives a network order so as to control the signal lamp to be on / off; 3, the signal lamp can detect a lamp color output state in real time and sends the state to the control equipment via the network, and the control equipment determines whether a signal lamp set output state in a crossing has abnormity or not; when the control equipment does not response, the signal lamp set in the crossing can form a network via theinternet, and continuously outputs a pre-stored lamp color output scheme in synergy; 4, if certain signal lamp is cut off from the network or damaged, the signal lamps can all enter a yellow lamp scintillation state.

Description

technical field [0001] The embodiments of the present application relate to the field of intelligent transportation, and in particular, to a traffic signal light control method and system. Background technique [0002] The traffic signal control system is used for the traffic light signal control of urban road intersections, pedestrian crossings and fast entrances, and its safety and reliability are related to the safety of traffic operation. The traditional traffic signal control system consists of two parts: signal machine and signal light. In the traditional signal control system, the signal machine is based on the control system of strong electric signal to control the signal light. The signal machine can only control the signal light output of one intersection. Multiple intersections), due to the limitation of the output interface, it can only control very few intersections, and there is a greater limit on the distance between the intersection and the signal.
