Intelligent traffic signal control machine based on Internet of things

Abstract

The invention relates to an intelligent traffic signal control machine based on Internet of things. The intelligent traffic signal control machine comprises a signal control machine terminal, a wireless transmission network and a monitoring platform, wherein the signal control machine terminal comprises a single chip microcomputer, a real-time clock module, a light color driving module, a keyboard module, a display screen, a signal output latching module, a signal output driving module, a signal light set module, a single chip microcomputer abnormal detection and RAM (Random Access Memory) data protection module, a green conflict detection module, a fault-tolerant control module, a GPS (Global Positioning System) global positioning module and a GSM (Global System For Mobile) communication module; the monitoring platform comprises a server in which an electronic map is arranged; the single chip microcomputer is connected with the real-time clock module, the light color driving module, the keyboard module, the display screen, the GPS global positioning module and the GSM communication module; the fault-tolerant control module is respectively connected with the green conflict detection module, the signal output driving module and the signal light set module. The intelligent traffic signal control machine has a fault-tolerant function and is capable of realizing wireless transmission and remote supervision and easier to realize intelligent traffic management.

Description

technical field [0001] The invention belongs to the field of traffic signal controllers, in particular to an intelligent traffic signal controller based on the Internet of Things. Background technique [0002] Transportation plays an important role in the development of the national economy. However, traffic jams often occur in most urban traffic. Not only is the speed of vehicles limited during driving, but also due to the interference of non-motorized vehicles and pedestrians, sometimes multiple red light signals are frequently encountered, making it difficult to achieve efficient and fast operation. Therefore, the signals of coordinated traffic hubs are very effective in improving the traffic capacity of urban roads. [0003] The traffic signal controller is the basic unit of the urban traffic signal control system and the key equipment to solve the urban traffic problems. At present, the systems used in countries all over the world need to install a large number of roa...

AI Technical Summary

Problems solved by technology

At present, the systems used in countries all over the world need to install a large number of road sensors. Most of the transportation hubs in my country do not have these conditions, and it is difficult to realize them in the near future.

The cost of a single traffic signal system in these systems is also very high, the system has poor fault tolerance and low security, and the failure of individual sensors may lead to the collapse of the entire system and the paralysis of the traffic system. This kind of signal control machine is difficult to realize in developing countries
