Fire extinguisher failure automatic alarm system applied to automobiles and its realization method

Abstract

The invention discloses a fire extinguisher failure automatic alarm system applied to an automobile. The system involves an automobile control system, a vehicle-mounted display screen, a pressure gauge, a mounting plate arranged inside the pressure gauge, a rotating shaft, a pointer, a sleeve and a dial, and the system further involves an angle transducer connected to the rotating shaft and used for monitoring the rotating angle of the rotating shaft, a control module arranged at the bottom of the mounting plate, a current monitor arranged at the bottom of the mounting plate and used for monitoring an output current value of the angle transducer and transmitting the output current value of the angle transducer to the control module, an audible alarm system arranged on the mounting plate and a wireless communication module used for transmitting control information output by the control module to the automobile control system; and the control module is used for comparing an received current value with an internal preset current value and outputting a control signal for determining the state of a fire extinguisher. According to the fire extinguisher failure automatic alarm system applied to the automobile, the purpose of reminding a driver to replace or maintain the fire extinguisher in time is achieved, automatic management is achieved, normal use of the fire extinguisher is guaranteed, and operation is simple and convenient.

Description

technical field [0001] The invention relates to the field of vehicle-mounted fire extinguisher management, in particular to a method for realizing an automatic fire extinguisher failure alarm system applied to automobiles. Background technique [0002] In recent years, there have been frequent reports of burning cars. There are more than dozens of car fires in cities above the middle level every year, and more fire times in expressway sections, and more than 80% of car fires have caused vehicle scrapping, or even car crashes. To prevent automobile fires, the best way to extinguish the fire in time is to prepare a fire extinguishing device in the car. Fire extinguishers are widely used because of their small footprint. [0003] In order to facilitate the observation of the state of the fire extinguisher, a pressure gauge is installed on the fire extinguisher to remind the driver of the state of the fire extinguisher, so as to replace the new fire extinguisher in time and avo...
