Problems solved by technology

On the one hand, this will cause each detector to have a wire connected to the controller to transmit its own measurement signal, which will undoubtedly increase the workload of installing the equipment; on the other hand, it will also limit the installation position of the detector, because These commonly used detection devices require AC power supply facilities, so they are generally installed near urban intersections with convenient power supply, and the vehicle speed information at the intersections can no longer truly reflect the driving conditions of vehicles in areas far away from the intersections

Embodiment Construction

[0022] The road traffic monitoring system shown in Figure 1 is composed of a control center 3, a wireless communication module 2 and an information collection system 1. The information collection system is composed of a wireless sensor node and a control node 4. The wireless sensor node is installed on the lane to measure traffic Traffic, driving speed and other information are collected, and the information is transmitted to the control node. The control node and the one-hop and two-hop wireless sensor nodes distributed in an area are organized into a two-hop star network, as shown in Figure 2, Figure 2 (a) is measuring flow data in various directions at an intersection such as measuring at an intersection. Figure 2(b) measures the traffic flow, driving speed and other data of each lane on the road away from the intersection. The control node obtains information from the wireless sensor node network on the one hand, and sends the information to the control center through the ...

Abstract

A monitoring system of road traffic is prepared for erecting radio transducer on lanes to measure traffic flow rate and driving speed and to transmit measured information to control node, organized control node and radio transducer distributed at a region to be a multi-jump star type of network being used to obtain information from radio transducer node network on one hand and on the other hand to send obtained information to control center through GPRS communication module.

Description

Technical field: [0001] The present invention relates to monitoring systems, especially traffic monitoring systems. Background technique: [0002] With the continuous increase of car ownership, urban road congestion is becoming more and more serious. In order to effectively guide urban traffic, the traffic management department must grasp the current driving conditions of urban roads in a timely manner, and the traffic information collection system is the key link to complete this task. There are many types of traffic information collection systems. At present, the most widely used in urban streets are induction coil detectors, ultrasonic detectors and video detectors. A common feature of these commonly used detection devices is that they do not cooperate with each other and complete their own tasks independently. For example, each induction loop detector is an independent unit, which is responsible for detecting vehicles passing through it, and has no relationship with ot...
