Packet type universal intelligent traffic signal machine

Abstract

The grouping-type universal intelligent traffic signal machine of the present invention comprises a central processing unit, a storage module connected with the central processing unit, a power supply, a crystal oscillator and a communication module; The module is connected with an interface chip, and the interface chip is connected with a traffic signal machine. The grouping type universal intelligent traffic signal machine of the present invention realizes the real-time communication and control between the GPRS network and the communication server, the system operates stably, and the system response time is 2s. This system adopts the GPRS wireless access method, and designs a group-type universal intelligent traffic signal machine, which realizes urban traffic control data communication and solves the problems of traditional wired communication methods in terms of network coverage, scalability, real-time performance and reliability. problem, reducing operating costs.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to a grouping type universal intelligent traffic signal machine. Background technique [0002] The data communication system is one of the important components of the urban traffic control system. Through data collection, transmission and management technology, the monitoring center can accurately obtain the traffic flow of each intersection of the road network and the operating status of the traffic signal, so as to ensure The control effect of the road network creates conditions. Therefore, how to quickly, accurately, and in real time upload the traffic flow data of each intersection and the operating status of traffic signals to the monitoring center, and how to transmit control commands to the signal from the monitoring center has become an important part of the efficient operation of the entire control system. At present, my country's existing urban traffic control system ne...

AI Technical Summary

Problems solved by technology

At present, my country's existing urban traffic control system network mainly uses wired methods such as telephones or special cables for data communication, which can no longer meet the real-time and mobility requirements of intelligent transportation system ITS and various intelligent vehicle-mounted mobile terminal data communications.
