Error judgment prevention stopping inductor of highway crossing ETC bar dropping device

Abstract

An error judgment prevention stopping inductor of a highway crossing ETC bar dropping device is composed of a distance induction device (1.1) and a motor stopping device (1.2). The distance induction device (1.1) is arranged on the front portion of the ETC bar dropping device (1), and the motor stopping device (1.2) is connected with the distance induction device (1.1) in series. Through the structure, when the motor stopping device (1.2) receives information sent by the distance induction device (1.1), a car stopping barrier is controlled in time, passing cars are made to pass directly, and the car stopping barrier is prevented from smashing the cars or influencing road running safety.

Description

technical field [0001] The invention relates to a safety device for dropping poles of an auxiliary ETC device used at high-speed crossings. Background technique [0002] The ETC (Electronic Toll Collection) device at the expressway crossing is the electronic non-stop toll collection system. Using this system, car owners only need to install the proximity card on the car window and pre-store the fee, and then they do not need to pay the toll manually when passing the toll booth, and there is no need to stop, and the high-speed toll will be automatically deducted from the card. This toll collection system takes less than two seconds per vehicle, and the traffic capacity of the toll channel is 5 to 10 times that of the manual toll channel. However, it has been found in practical work that when the traffic flow is large, especially when two vehicles pass through the sensing area at the same time, the ETC drop bar device is prone to misjudgment, resulting in the accidental drop ...

Problems solved by technology

However, in practical work, it has been found that when the traffic flow is large, especially when two vehicles pass through the sensing area at the same time, the ETC drop bar device is prone to misjudgment, resulting in accidental drop of the parking rail and incidents of smashing vehicles.
