| 摘 要： | 为了避免因机动车自燃带来的人身和财产损害,文章设计了车载火灾报警器,其用单片机做主控制芯片,采用K型热电偶和MAX6675芯片对机动车上的易燃点和基准点的温度进行实时检测,当比较到易燃点温度和基准点温度超过设定的允许温差值时,发出报警。进行了车载火灾报警器运行和测试实验,获得了预期的结果,检测到了机动车易燃点与基准点的温度差值,据此实现了对机动车自燃火灾的预报警。

| Abstract: | In order to avoid the personal and property damage due to spontaneous combustion of motor vehicles, this paper designs a vehicle fire alarm. It adopts MCU as the control chip, uses K type thermocouple and MAX6675 chip to real time detect the temperature of flashpoints and reference points on the motor vehicle, when the temperature difference between the flashpoints and reference points exceeds the allowed temperature difference value setting, alarm signal is sent. The running and testing experiments for the fire alarm are carried out, obtaining the expected results, which include the temperature difference between flashpoints and reference points values, so that the pre-alarm of motor vehicle＆#39;s spontaneous combustion is implemented. |
