Self-powered device for detecting illegal occupation of bus lane

Abstract

The invention discloses a self-powered device for detecting illegal occupation of a bus lane, which belongs to a traffic detection device and comprises a first piezoelectric axis sensor which is laid under the ground of the bus lane, is perpendicular to a lane of the bus lane and is used for detecting coaxial double-wheel passing of a vehicle, a second piezoelectric axis sensor which is parallel to the first piezoelectric axis sensor, a first signal processor and a second signal processor which are used for receiving signals transmitted by the first piezoelectric axis sensor and the second piezoelectric axis sensor when two coaxial wheels of the vehicle pass through and carrying out filtering, rectification and amplification processing on the signals, an energy storage device for providing electric energy, a controller for controlling the whole device, a camera used for shooting vehicles occupying the bus lane illegally and is hung on one side of the bus lane, and an LED display screen for warning the violation vehicle. According to the device, the labor cost is reduced, the service life is long, and compared with an existing bus lane detection device, the device is better.

Description

technical field [0001] The invention relates to a traffic detection device, in particular to a self-powered bus lane violation detection device. Background technique [0002] Environmental protection is a contemporary development concept, while energy conservation is a long-term development strategy for my country's sustainable development, and it is also a basic national policy of our country. At present, my country's power supply is generally tense, which has become a "bottleneck" restricting the development of the national economy. Scientists set out on a quest to create devices that could convert other energies into electricity. Self-powered devices came into being. Nowadays, there are many highways in our country, and the traffic volume on the roads is also increasing. The vehicles on the roads are constantly coming and going, and the load of each vehicle is also very large. When the vehicle drives across the ground, it will generate a lot of force (vibration) on the...

AI Technical Summary

Problems solved by technology

[0004] (1) The detection equipment used in the device is mostly a vehicle camera or an intersection camera, which needs to be turned on all the time, which consumes power and wastes memory, and increases the workload of the traffic police to call out and check later

Among them, the on-board device can only capture the illegal occupancy of a certain distance in front of the bus, but cannot capture other vehicles that are not in front of the bus and illegally occupy the bus lane, which is unfair to a certain extent;

[0005] (2) The devices are all powered by ordinary electricity, which is not energy-saving and environmentally friendly compared to self-powered detection devices;

[0006] (3) There are a small number of inventions that use the ground road sense coil for detection, but it is only suitable for the detection of other vehicles parked at the station, and must be parked in the detection area, which has limitations
