Traffic flow monitoring system based on automobile electronic marker and monitoring method thereof

Abstract

The invention provides a traffic flow monitoring system based on an automobile electronic marker and a monitoring method thereof and relates to the field of traffic flow counting. The traffic flow monitoring system comprises a console, a display device, a marker reader and an electronic marker; the marker reader arranged beside of a lane of an expressway is in wireless communication with the electronic marker arranged on an automotive vehicle and is used for transmitting communication data to the console in real time; the console is used for processing the communication data and displaying the communication data through the display device; the traffic flow monitoring system further comprises a pressure sensor embedded on the ground of the lane; the pressure sensor is used for transmitting a collected pressure value to the console in real time; and the console is used for judging whether the marker reader at a dormant state is awakened or not according to the pressure value. According to the traffic flow monitoring system provided by the invention, the electronic marker is awakened through utilizing pressure on the ground in an automobile driving process, and the marker reader in wireless communication with the electronic marker, so that a low omission rate is realized; and a communication behavior consumes a lot of power and a dormant-awaking mechanism is added, so that a radio frequency signal is transmitted by the marker reader only if an automobile passes through, the waste of electric energy is avoided and high-efficiency energy saving is realized.

Description

technical field [0001] The invention relates to the field of traffic flow statistics, in particular to a vehicle flow monitoring system and a monitoring method based on automobile electronic signs. Background technique [0002] Traffic flow is the number of motor vehicles passing through a certain road section within a certain period of time. At present, the statistical method of traffic flow in expressways generally adopts video monitoring method, which uses computer recognition technology to extract the required information from video image sequences. , so as to achieve the purpose of counting the traffic flow. The disadvantage of the video monitoring method is that the computer recognition technology is not perfect at this stage, and there is a risk of omission in the image extraction. Moreover, the camera used to collect the image needs to work continuously for 24 hours, and there are no vehicles on the road. When the camera is also working, causing a waste of electric e...
