Electromagnetism speed reduction device and method

Abstract

An electromagnetism speed reduction device comprises a power supply unit, a detection unit and a control unit. The power supply unit comprises a system power source, a detection power source and a control power source, wherein the detection power source and the control power source are connected with the system power source in parallel. The detection unit comprises a detector electrically connected with the detection power source. The control unit comprises a speed reduction coil and a threshold value opening valve, and the speed reduction coil is buried below a pavement and reduces the speed of vehicles by generating an electromagnetic field when electrified. The threshold value opening valve is electrically connected with the speed reduction coil and the detector and used for judging parameters detected by the detector. The control unit and the detection unit are connected to the power supply unit in parallel in a paired mode. By generating the electromagnetic field, the electromagnetism speed reduction device reduces the speed of all the vehicles passing through the road section with the electromagnetism speed reduction device and is high in applicability.

Description

【Technical field】 [0001] The invention belongs to the field of highway traffic safety, and in particular relates to an electromagnetic deceleration device and a method thereof. 【Background technique】 [0002] From the analysis of vehicle operating characteristics, long downhill road sections generally refer to long-distance, high-slope road sections that are likely to cause long-term braking or neutral sliding on the linear design. According to statistics, the length of the long downhill road section in my country accounts for less than 20% of the total length of the road network, while the traffic accidents on the long downhill road section account for more than half of the total accidents, and the traffic accidents caused by the brake failure of the heavy-duty vehicles on the long downhill road section account for the total traffic accidents of this road section. 70%-90%, so the long downhill section is also called "accident-prone section". [0003] Vehicles, especially he...

Problems solved by technology

Although installing a retarder on a vehicle can have a deceleration effect to a certain extent, for trucks that are prone to brake failure, there is generally no expensive retarder. Simply installing a water spray device to cool down the brakes of the vehicle does not prevent Fundamentally solve the problem that the excessive braking load of the vehicle leads to the decrease of braking efficiency and the failure of braking
