Abstract

The invention discloses a WIFI signal-based traffic flow detector and a detection system. The detection system comprises a traffic flow detector, a data storage and analysis system and a communication network. The traffic flow detector comprises a signal receiving and transmitting module, a signal transmission module and a power supply module. The signal receiving and transmitting module is used for sending the WIFI broadcast so as to trigger a mobile device to send signals to the periphery, and receiving data sent from the mobile device, wherein the data are composed of the identification code of the mobile device. The signal transmission module is used for sending the received data to the data storage and analysis system. The data storage and analysis system is used for storing the data and calculating the traffic flow according to the data. The communication network is used for enabling the data transmission between the traffic flow detector and the data storage and analysis system. In this way, no positioning software or positioning device needs to be installed forcibly, so that the usage cost is low. The detector is high in durability and convenient to install, which can be densely arranged on each road section. The detector is low in power consumption, small in energy consumption, green and environment-friendly.

Description

technical field [0001] The invention relates to traffic flow detection technology, in particular to a detector and a detection system used in environments such as expressways. Background technique [0002] Traffic flow data is an important source of information for the traffic operation dispatching command system, which can provide decision-making basis for command dispatching, traffic flow control and traffic guidance. There are many kinds of existing traffic flow detection technologies, which can be divided into contact detection methods and non-contact detection methods according to the installation method. Among them, the contact detection technology includes piezoelectric, pressure tube detection and loop coil detection. The main disadvantage of this technology is that the service life of the detector is short due to the rolling of the vehicle on the road. When the detector is deployed, it is necessary to interrupt the traffic and damage the road surface. Therefore, it...
