Abstract

The invention discloses an anti-rollover control and alarm system for a hazardous chemical substance vehicle. The anti-rollover control and alarm system comprises a chassis, a measuring unit, an alarmunit, a control unit and an anti-rollover unit, wherein the chassis comprises wheels, an axle, a suspension, a vehicle frame and a tank body fixed on the vehicle frame, the measuring unit comprises avehicle speed sensor used for collecting a vehicle speed value and a steering wheel angle sensor used for collecting a steering wheel angle value, the anti-rollover unit comprises a vehicle correction module, a parking brake control module and a pneumatic control module, the vehicle correction module comprises a first displacement sensor and a second displacement sensor which are used for measuring the rollover displacement of the vehicle as well as a correction air cylinder used for straightening the vehicle frame when the vehicle is tipped over, and the parking brake control module comprises a parking brake air cylinder used for tensioning a brake steel wire to enable the hazardous chemical substance vehicle to be automatically braked. According to the anti-rollover control and alarm system for the hazardous chemical substance vehicle, the vehicle-mounted stability control system is designed mainly for the particularity of the hazardous chemical substance vehicle and the particularity of loaded objects so as to improve the early warning and active intervention functions of the hazardous chemical substance vehicle under the dangerous working condition.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to an anti-rollover control and alarm system for a hazardous chemical vehicle. Background technique [0002] Hazardous chemical vehicles transport dangerous chemicals, flammable and explosive materials, or toxic and harmful materials. Once a road transportation accident occurs, it will cause great harm to the drivers and passengers, the surrounding people and the environment. Especially for vehicles carrying non-solid hazardous chemicals, the medium is sloshing during the running of the vehicle. When the tank is not filled with liquid, the center of gravity is shifted, and the liquid will produce a shock effect during the shaking process. In this way, the roll stability of a tank truck loaded with liquid cargo and a vehicle loaded with solid cargo of the same mass will change greatly when turning. When the hazardous chemical vehicle turns at a certain speed, due to the dev...
