摘 要随着汽车的普及程度提高，车辆安全隐患逐渐被人们重视，其中高温条件下车体和乘车人员的安全隐患发生频率较高却未得到足够重视。本文设计了一种基于 51 单片机应用的夏季车辆自动喷淋降温系统。本系统共五个模块，分别是红外检测模块、温湿度检测模块、显示模块、蓝牙模块和喷淋模块。红外检测模块可以实时检测特定空间内是否有车辆停放，当有车辆停放时，温湿度模块通过 DHT11 检测环境的温、湿度，并由显示模块展示数据，由蓝牙模块在一定范围内将数据传送给单片机进行判断，若实时温度高于阈值，则启动喷淋模块降温；当没有车辆停放时，不启动其他模块。经过多次调试，逐一实现了夏季车辆自动喷淋降温系统的功能，并且在实际应用中，本系统具备智能性和环保性，能为人们的生活带来更多的方便与快捷。关键词：喷淋降温系统；单片机；温湿度检测；红外检测；蓝牙PAGE \* MERGEFORMAT2AbstractWith the increasing popularity of automobiles, vehicle safety hazards have gradually been paid attention to. Among them, the safety hazards of car bodies and passengers at high temperatures have become a hidden hazard with a high frequency but insufficient attention. This paper designs an automatic spray cooling system for vehicles in summer based on the application of 51 single chip microcomputer. And the control system consists of five modules: infrared detection module, temperature and humidity module, display module, Bluetooth module, spray module. The infrared detection module can detect whether there are vehicles parked in a specific space in real time. When a vehicle is parked, the temperature and humidity module detects the data through the sensor, and the data is displayed by the display module, and the Bluetooth module transmits the data to the single chip microcomputer for judgment within a certain range. If the real-time temperature is higher than the threshold, the MCU starts the spray module to cool down. When no vehicle is parked, other modules are...
