微型电脑应用

为了降低车内安全事故发生概率，提出一种以物联网与FPGA相结合的智能安全监测系统，采用温度、湿度、酒精、红外等多种传感器对车内环境和人员滞留进行检测，通过GPRS实时接收监测数据，并将其发送给智能手机终端以及显示在OLED屏上，从而实现自动环境监测功能。在环境监测的过程中，监测系统一旦发现车内温湿度、酒精、CO₂传感器以及乘车人数超过安全阈值就会立即发出警报，确保车内安全。利用FPGA对车内安全检测系统进行板级测试，测试结果表明，此系统可以较好地对车内环境进行监测，提高了安全性，具有一定的实际意义和应用价值。

To reduce the probability of safety accidents in the car, this paper proposes an intelligent safety monitoring system that combines the Internet of Things with FPGA, uses a variety of sensors such as temperature, humidity, alcohol and infrared to detect the environment inside the car and personnel retention. The real-time monitoring data are received through GPRS, and sent to the smartphone terminal for displaying on the OLED screen, realizing the automatic environmental monitoring function. In the process of monitoring environment, once the monitoring system finds that the temperature and humidity, alcohol, CO₂ sensors, and the number of passengers exceed the safety threshold, it will immediately sound an alarm to ensure safety in the car. The in-car safety detection system is tested by FPGA at board-level. The test results show that this system can better monitor the interior environment and improve the safety. It is of certain practical significance and application value.
