Description
Technical Field
The invention relates to a bus driving area intrusion safety guarantee device, and belongs to the technical field of bus safe driving.
Background
Passengers conflict with bus drivers, the passengers lose intelligence due to anger and fire, and the steering wheel events of robbing the bus drivers happen frequently, so that the safety of the vehicles and the passengers faces great threats. In order to ensure the safety and prevent risks of drivers, many places take many protective measures in succession, such as providing buses with necessary safety isolation rooms, isolating the drivers from passengers and installing protection nets, and the like, and some buses are provided with professional security personnel. The adoption of the measures can really play a certain role in hindering criminals from doing criminals. However, the problem cannot be fundamentally solved. For example, a perpetrator can injure a driver by using a rod-shaped sharp tool through a gap of the isolation door or the protective net, and the potential safety hazard is still great. If each bus is provided with a totally-enclosed firm and durable isolation room, the cost is huge, new hidden dangers are brought, and great difficulty is brought to rescue in case of sudden diseases and the like of a driver.
Disclosure of Invention
The invention aims to provide a bus driving area intrusion safety guarantee device, when the driving area encounters illegal intrusion, a vehicle can automatically start a braking system to decelerate and flameout the vehicle.
In order to achieve the purpose, the invention provides an intrusion safety guarantee device for a bus driving area, which comprises a microcontroller, a speed relay, a steering wheel angle sensor and a plurality of intrusion detection switches, wherein the microcontroller is used for controlling the speed relay to work; the intrusion detection switch is arranged below the floor of the right area of the driving seat and is connected with the microcontroller; the vehicle speed relay is connected with the vehicle exhaust brake switch in parallel and is controlled by the microcontroller; the steering wheel angle sensor is arranged on the steering wheel and connected with the microcontroller.
When a person invades the driving area, the foot of the person can step on the invasion detection switch, and the invasion detection switch is closed; if someone snatches the steering wheel with the driver, the change of steering wheel angle by a wide margin, high frequency can appear. Therefore, when the microcontroller detects that the intrusion detection switch is closed and the angle of the steering wheel is changed greatly at high frequency, the situation that a person invades a driving area and snatches the steering wheel with a driver at the moment is shown, the microcontroller controls the vehicle speed relay to be closed, and the braking system is started automatically to reduce the speed.
The invention has simple circuit, small and exquisite equipment, low cost and convenient installation, and only needs to disassemble and change the original line of the transport vehicle a little when in installation; the invention can automatically judge whether a person invades the driving area of the bus or not, rob the driver steering wheel, automatically start the exhaust braking system, and avoid traffic accidents caused by incapability of handling by the driver in emergency situations without active intervention of the driver.
Drawings
FIG. 1 is an electrical schematic of the present invention.
Detailed Description
The invention will be further explained with reference to the drawings.
As shown in fig. 1, the intrusion safety guarantee device for the bus driving area comprises a microcontroller, a speed relay steering wheel angle sensor and a plurality of intrusion detection switches; the intrusion detection switch is arranged below the floor of the right area of the driving seat and is connected with the microcontroller; the vehicle speed relay is connected with the vehicle exhaust brake switch in parallel and is controlled by the microcontroller; the steering wheel angle sensor is arranged on the steering wheel and connected with the microcontroller.
Further, the present invention also includes an alarm, which is controlled by the microcontroller. When someone invades the driving area, the alarm can be started to remind the invader to leave.
Further, the invention also comprises a flameout loop; the flameout loop comprises a flameout relay and an oil cut-off electromagnetic valve; the oil cut-off electromagnetic valve is connected in series in a vehicle oil supply loop and is controlled by a flameout relay, and the flameout relay is controlled by a microcontroller; the microcontroller is connected with the vehicle speed sensor. When the microcontroller detects that the vehicle speed is reduced to a set value, if the microcontroller detects that the intrusion detection switch is closed and the large-amplitude high-frequency change of the steering wheel angle still exists, the oil cut-off electromagnetic valve is controlled to be switched off directly through the flameout relay, so that the vehicle is flamed out.
Furthermore, the invention also comprises an exhaust brake indicator light which is connected with the vehicle speed relay in series; the vehicle speed relay loop work indication device is used for vehicle speed relay loop work indication. The invention belongs to an emergency device, does not work at ordinary times, and can be directly removed to avoid influencing the normal running of a vehicle if a driver finds that an exhaust brake indicator lamp is on.
Furthermore, the invention also comprises a remote alarm which is connected with the microcontroller. Used for sending linkage alarm information to 110 and a public transport company.
