Intermediate gate safety devices on buses with speed limiters

摘要

The present invention relates to an intermediate door safety device for a bus to which a speed limiting device is attached. When a predetermined signal generated by a vehicle speed sensing portion is applied to a speed limiting central processing unit, a diode And a signal generator for generating a signal of a specific frequency occurring during overspeed of the bus between the diode and a signal input terminal of the speed limiting central processing unit, When the intermediate door of the bus is opened, a certain frequency generated when the bus is operated at a speed higher than the reference speed is generated, so that the driving of the vehicle is directly blocked from the speed limiter, So that the driver ' Remove the risk of accidents caused by mistakes by fully and to increase the safety of the passengers.
