Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] Such as figure 1 As shown in the overall structure block diagram: the overall structure block diagram includes the detection module; the minimum system composed of the STM32F103ZET6 chip as the core completes the system control and data processing functions through the connection of the I / O interface and the peripheral circuit; the display module performs the measurement data Real-time display; alarm module, which can alarm when the temperature exceeds the set value or the smoke concentration is too high.

[0015] Such as figure 2 As shown in the schematic diagram of the relay connection structure: multi-channel relays are connected in parallel. As long as one smoke sensor detects smoke, the active buzzer triggered by the low level will alarm. The COM port of this relay is grounded, and the NO normally open switch is selected. The relay is triggered by a low ...

Abstract

The invention relates to a distributed non-contact measurement early warning system for a vehicle spontaneous combustion phenomenon, which is specifically applied to early warning of the vehicle spontaneous combustion phenomenon to achieve real-time monitoring and early warning of vehicle temperature and smoke concentration. Aiming at a fire disaster caused by a vehicle circuit system fault and threatening human life, the invention provides an early warning monitoring system, which comprises a detection module taking a smoke sensor MQ-2, a non-contact infrared temperature sensor MLx90614 and atemperature sensor DS18B20 as cores, a minimum system taking an STM32F103ZET6 chip as a core, an additional display module TFT LCD screen and an alarm module active buzzer, the system can achieve thefunctions of real-time data measurement, data display and early warning, is practical and intelligent, is simple in design, is wide in application range, is high in universality, is lower in cost, and is convenient to use.

Description

technical field [0001] The invention mainly designs a distributed non-contact measurement and early warning system for spontaneous combustion of vehicles, which is applied to the detection and early warning of spontaneous combustion of vehicles, so as to realize real-time monitoring and safety early warning of vehicle temperature and smoke concentration. Background technique [0002] With the development of my country's vehicle industry and the improvement of people's living standards, more and more spontaneous combustion of vehicles has appeared in the public's field of vision. Spontaneous combustion may occur, especially in hot summer. Due to the influence of the environment and automobile manufacturing technology, there are more and more examples of threats to people's lives and property losses when automobile spontaneous combustion occurs. In order to prevent the fire caused by the failure of the circuit system and the threat to human life, the early warning system can p...
