Intelligent traffic signal control system based on Raspberry Pi and Internet

Abstract

The invention relates to an intelligent traffic signal control system based on the Raspberry Pi and the Internet. The intelligent traffic signal control system comprises an underground detection module, a signal display module, a control decision-making module, an image acquisition module, a network connection module, a remote terminal and a display interface module. The network connection module,the image acquisition module, the signal display module, the underground detection module and the display interface module are connected with the control decision-making module. The control decision-making module includes a Raspberry Pi controller. The network connection module includes a Raspberry Pi WiFi module and a cloud server; the Raspberry Pi WiFi module is connected with a network to invoke a Chinese weather network API interface and an Amap official website API interface. Meanwhile, the Raspberry Pi WiFi module is connected with the network to connect the Raspberry Pi controller withthe cloud server and the remote terminal. The image acquisition module includes a camera and a steering engine; and the rotation angle of the camera is set to be a vehicle coming direction of a detected lane and a pedestrian waiting area direction arranged in the vehicle incoming direction. The system expands network interfaces and network communication is realized.

Description

technical field [0001] The invention relates to the field of traffic signals, in particular to an intelligent traffic signal control system based on Raspberry Pi and the Internet. Background technique [0002] The research and advancement of intelligent transportation is still in the initial stage of exploration in our country. Although the signal lights at the intersections of urban roads in our country are automatic, the signal conversion is still in a fixed timing state. However, the fixed timing control cannot adapt to the randomness and variability of pedestrians and vehicles at intersections, and there are often phenomena such as emptying and waiting, multiple parking, and pedestrians running red lights. [0003] In recent years, intelligent traffic lights have developed rapidly, and there are various schemes. For example, Chinese patent CN207123946U discloses a kind of intelligent traffic light control device aimed at pedestrian gathering areas. Optimize time, alloc...

Problems solved by technology

For example, Chinese patent CN207123946U discloses a kind of intelligent traffic light control device aimed at pedestrian gathering areas. Optimize time, allocate traffic light time, the STM32 in the device is only used to control the steering gear, which increases the difficulty of control and also increases the cost

At the same time, only the control and computing capabilities of the Raspberry Pi have been developed, and no network development has been carried out on it, so the effect is not ideal
