Bus safety control system

Abstract

The invention discloses a bus safety control system. When the rear cabin door of a bus is opened, a normally-closed contact of a magnetic induction rear safety switch K2 is closed, a starter M cannotreceive the electric energy provided by a direct-current power supply V1 and thus cannot be started, an LED 1 indicating lamp arranged on a dashboard is lightened, and the vehicle cannot be started, such that the starter M can be started only when the rear cabin door of the bus is closed, therefore casualties are effectively avoided and the safety is greatly improved. When a neutral position switch K3 is switched on, a driver presses down a rear start button K4 at an engine compartment, then the starter M is turned on; if the neutral position switch K3 is not switched on, even if the rear start button K4 is switched on, the starter M cannot be connected with the direct-current power supply V1 and cannot be started; and if a driver or a maintainer starts the starter M in the engine compartment, the whole vehicle can be started only when being in a neutral position (namely, the neutral position switch K3 is switched on), so that the vehicle is effectively prevented from being started when being in the gear position, and safety accidents are prevented.

Description

technical field [0001] The invention relates to the field of safety control systems, in particular to a bus safety control system. Background technique [0002] As an important means of transportation, buses have a huge impact on society and play a fundamental role in promoting urban development. Since the bus is generally equipped with a rear engine and the length of the bus is long, under normal circumstances, when the driver starts the vehicle in the cockpit, it is impossible to accurately predict whether there is an unrelated person in the engine compartment of the vehicle, which will cause the accident light to occur. If the rear hatch is open when starting and there are unrelated persons in the engine compartment, it will easily cause casualties if the engine is started. Contents of the invention [0003] The purpose of the present invention is to provide a public transportation safety control system to solve the problem that the driver cannot accurately predict the...

Problems solved by technology

[0003] The purpose of the present invention is to provide a public transportation safety control system to solve the problem that the driver cannot accurately predict the vehicle engine when starting the vehicle in the cockpit due to the fact that the bus is generally equipped with a rear engine and the length of the vehicle is relatively long. Is there any unrelated personnel in the cabin checking, resulting in the occurrence of the accident light, if the rear hatch is open when starting, and there are unrelated personnel in the engine compartment, if the engine starts, it will easily cause technical problems of casualties
