Emergency control circuit of school bus

Abstract

The invention discloses an emergency control circuit of a school bus. The emergency control circuit which conforms to emergency disposal regulations in our country according to safety specifications for special school buses comprises a power supply switch, an electromagnetic power master switch, a battery, an ignition lock, a left steering signal light, a right steering signal light, an interior dome light, a courtesy lamp, an emergency switch and an electrically controllable switch device; the emergency switch comprises a group of normally open and normally closed contracts and a group of normally open contacts; a positive electrode of the battery is connected with movable contacts of the group of normally open and normally closed contracts of the emergency switch; normally open stationary contacts of the group of normally open and normally closed contracts are connected with a control terminal of the electrically controllable switch device; normally closed stationary contacts of the group of normally open and normally closed contracts are connected with a control terminal of the electromagnetic power master switch through the power supply switch; and a group of normally closed contacts of the emergency switch are arranged in an ignition control circuit in a serial mode. The emergency control circuit of the school bus has the advantages of greatly improving the controllability and being simple to operate due to the fact that the emergency control circuit is integrated into an electrical control circuit of an integral vehicle.

Description

technical field [0001] The invention relates to an electric control circuit, in particular to a school bus emergency control circuit. Background technique [0002] As we all know, the emergence of school buses, on the one hand, provides great convenience for primary and middle school students to go to and leave school. security incident. For this reason, our country incorporates the emergency switch that must be installed in the school bus into the "Special School Bus Safety Technical Conditions", which requires the school bus to stop the engine quickly after the emergency switch is activated, and start the emergency lighting in the car (part of the car lights and passenger door steps) light), turn on the vehicle hazard warning signal, and cut off the main switch of the electromagnetic power supply. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a school bus emergency control system that can stop the engine qu...
