Description

Technical Field

[0001] The utility model relates to the technical field of fire detection, in particular to a visual vehicle-mounted battery fire detection and alarm device. Background Art

[0002] Battery overheating is one of the main causes of vehicle fires. In order to warn of battery fires in advance, a vehicle-mounted fire alarm device is usually installed. The vehicle-mounted fire alarm device can detect the working environment information of the battery and judge whether the battery may catch fire in advance based on whether the environmental information is abnormal. However, the existing vehicle-mounted fire alarm device can only issue an alarm prompt when a fire occurs, but cannot immediately indicate the specific location of the fire, which delays the time for the driver to intervene and judge, and thus makes it impossible for the driver to promptly contain the spread of the fire.

[0035] The alarm detection module is evenly distributed around the battery in an array. The alarm detection module includes: a temperature sensor for detecting the battery operating temperature information; a smoke sensor for detecting the environmental smoke parameters; a data processing module connected to the temperature sensor and the smoke sensor, used to determine whether a fire has occurred based on the temperature information and the environmental smoke parameters and generate alarm data, and the data processing module is connected to the communication interface module, used to send the temperature information and the environmental smoke parameters to the MCU main control unit, and display them through the display module.

[0037] The MCU main control unit is specifically a microcontroller unit (MCU). In some embodiments, the MCU main control unit can also be a central processing unit (CPU), a microprocessor (microprocessor), a digital signal processor (DSP), a programmable controller, a programmable logic device (PLD) or other similar devices or a combination of these devices, and the present invention is not limited. In addition, in some embodiments, each function of the MCU main control unit can be implemented by multiple coding programs, which are stored in a storage medium and executed by the MCU main control unit. Alternatively, in some embodiments, each function of the MCU main control unit can be implemented by one or more circuits.

[0038] The alarm module includes an audible and visual alarm and a buzzer. The alarm information includes audible and visual alarm information and buzzer alarm information. The audible and visual alarm information is emitted by the audible and visual alarm and the buzzer alarm is emitted by the buzzer to prompt the driver. The buzzer can emit buzzing sounds of different frequencies according to the different fire degrees fed back in the alarm data to prompt the driver.

[0039] The display module is specifically a display screen. Of course, in some embodiments, the MCU main control unit can also be connected to the vehicle's on-board system, and the display screen of the on-board system with a display screen can be directly used as the display module.

[0040] Furthermore, the MCU main control unit is also connected to a button module, which is used to cancel the alarm information by pressing.

The MCU main control unit processes the alarm data. Since the alarm data issued by different alarm detection modules will carry their corresponding location information or coding information, the source of the alarm data can be determined by reading this information, and then the location of the alarm can be obtained, and displayed through the display module. Since the display module is arranged on the dashboard in the car, the driver can check the alarm data at any time during driving. When the environmental data is abnormal, the alarm module can issue an alarm message to promptly prompt the driver.
