A vehicle flow counting method, system, device and computer storage medium

Abstract

The embodiment of the invention discloses a vehicle flow counting method, system, equipment and computer storage medium. The method includes: respectively obtaining the first distance collected by the first sensor and the second distance collected by the second sensor; the first sensor and the second sensor are respectively arranged on both sides of the vehicle passing through the channel, and the first The distance between a sensor and the second sensor satisfies a preset condition; when no vehicle passes by, the first distance and the second distance characterize the width of the channel; according to the first distance and the The second distance judges whether there is a vehicle passing by, and obtains a judgment result; controls the state switching of the state machine based on the judgment result, and counts the number of vehicles passing through the passage based on the state switching of the state machine.

Description

technical field [0001] The invention relates to the Internet of Things technology, in particular to a vehicle flow counting method, system, equipment and computer storage medium. Background technique [0002] In the era of the Internet of Things, the parking lot is an important application scenario of the Internet of Things. An important manifestation of the application of the Internet of Things is the ability to provide real-time and accurate data to support the operation of the parking lot. Among them, the number of vehicles entering and exiting the entrance and exit of the parking lot is an important parking lot operation data. [0003] The traffic flow statistics scheme at the entrance and exit of the existing parking lot often adopts the mode of electric brake lever, one lever for one vehicle. In actual operation, the renovation cost of the parking lot is high, and vehicles need to stop and lift the pole to enter and exit, which reduces the efficiency of entry and exi...

In actual operation, the renovation cost of the parking lot is high, and vehicles need to stop and lift the pole when entering and exiting, which reduces the efficiency of entering and exiting

For the statistical method based on the geomagnetic sensor, by placing a magnetic field next to the giant magnetoresistive sensor, the change of the magnetic field when the car passes by causes the output change of the sensor, and the passing car is judged by the output change of the sensor, and the measured traffic flow information is passed through The radio frequency is sent to the base station for storage. Although this method can count the order of magnitude of vehicles passing by, it cannot achieve accurate statistics.
