A bus driving area invasion safety guarantee device

Abstract

The invention discloses an invasion safety guarantee device for a bus driving area. The invasion safety guarantee device comprises a microcontroller, a vehicle speed relay, a flameout relay, a steering wheel angle sensor and a plurality of invasion detection switches. The invasion detection switches are arranged below the floor in the right side area of the driving seat and connected with the microcontroller; the vehicle speed relay is connected with a vehicle exhaust brake switch in parallel and is controlled by the microcontroller; the flameout relay is connected with a vehicle fuel cut-offelectromagnetic valve circuit in series and controlled by the microcontroller; the steering wheel angle sensor is arranged on the steering wheel and connected with the microcontroller. The circuit ofthe device is simple, the equipment is small and exquisite, and installation and connection are convenient. Whether someone invades the bus driving area and grabs the driver steering wheel or not is automatically judged; active intervention of the driver is not needed, an exhaust braking system and the fuel cut-off electromagnetic valve are automatically started, so the bus is decelerated until flameout and stopped, thus preventing traffic accidents caused by the fact that the driver cannot control the bus in emergency.

Description

technical field [0001] The invention relates to an intrusion safety guarantee device for a driving area of ​​a bus, belonging to the technical field of safe driving of a bus. Background technique [0002] Passengers clashed with the bus driver. Passengers lost their minds due to anger, and incidents of snatching the bus driver's steering wheel occurred frequently. The safety of vehicles and passengers faced a major threat. In order to ensure the safety of drivers and prevent risks, many places have adopted many protective measures, such as equipping buses with necessary safety isolation rooms, isolating bus drivers and passengers and installing protective nets, etc. What's more, some buses There are full-time security personnel on board. The adoption of these measures can indeed play a certain role in hindering the criminals. However, the problem cannot be fundamentally solved. For example, perpetrators can use stick-shaped sharp objects to injure drivers through the gaps...

AI Technical Summary

Problems solved by technology

However, it cannot fundamentally solve the problem

For example, perpetrators can use stick-shaped sharp objects to injure drivers through the gaps in isolation doors or protective nets, and the potential safety hazard is still great.

If each bus is equipped with a fully enclosed and durable isolation room, it will not only cost a lot, but also bring new hidden dangers. In case the driver has a sudden illness or other situation, it will cause great difficulties to the rescue
