Embodiment Construction

[0008] Such as figure 1 The illustrated GPRS-based urban traffic signal control system includes a central server, an intersection signal control machine, a detection system, and a communication system. The signal output end of the detection system is connected to the signal input end of the intersection signal control machine, and the intersection signal control machine The data communication is completed with the central server through the communication system, the intersection signal control machine controls the work of the red street lights, and the detection system is a loop coil buried under the road.

[0009] When the present invention works, the detection system is responsible for real-time collection of traffic flow information, and the communication system serves as a bridge link connecting other components. It can quickly, accurately and real-timely transmit the traffic flow information collected by each intersection detection system to the command center, so that traff...

Abstract

The invention discloses a GPRS-based urban traffic signal control system in the field of traffic signal management systems. The GPRS-based urban traffic signal control system comprises a central server, an intersection signal controller, a detection system, and a communication system. The signal output end of the detection system is connected with the signal input end of the intersection signal controller. The intersection signal controller performs data communication with the central server via a communication system and controls traffic signal lamps to operate. The GPRS-based urban traffic signal control system is simple in structure, easy to produce, low in cost, small in coverage, and good in anti-interference capability, and can be used in traffic signal lamp control.

Description

Technical field [0001] The invention relates to a traffic signal control system, in particular to a GPRS-based urban traffic signal control system. Background technique [0002] The control and management of urban traffic signals is what any modern city needs to face. In terms of improving road traffic conditions and reducing losses caused by traffic jams, urban traffic signal control systems play an irreplaceable role. The quality of its control and management directly affects the effects of urban road traffic jams or dredging. Summary of the invention [0003] The purpose of the present invention is to provide a GPRS-based urban traffic signal control system, which overcomes the shortcomings of high cost, small coverage, and susceptibility to interference caused by wired communication. [0004] The purpose of the present invention is achieved as follows: a GPRS-based urban traffic signal control system, which is characterized by comprising a central server, an intersection signal...
