基于IOT通信的智能汽车监测系统设计

无人驾驶智能车是目前汽车行业最前沿的研究之一，在民用、军事等方面得到了广泛的应用，前景广阔。目前，无人驾驶技术存在的问题是上路之后的安全问题，在无人驾驶智能车上安装远程监测系统，可有效避免安全事故的发生。文中用四驱智能车来模拟智能汽车的运动，用主控机来监测光耦传感器、加速度传感器和GPS定位传感器的信息，并通过IOT模块实现智能车与接收终端的通信，监测无人驾驶智能车的位置、加速度、转速信息等。采用IOT模块，选择MQTT协议，以便于信息的发送以及对智能车的控制，该方法具有成本低、技术相对可靠等优点。实验验证，该系统可在固定区域内对智能车进行无线监控，在网络环境良好的情况下，信息接收较为及时，安全性和可靠性较强。

Design of Intelligent Vehicle Monitoring System Based on IoT Communication

The driverless smart car is one of the most cutting-edge research in the automotive industry at present, and has been widely used in civilian and military aspects, with broad prospects. At present, the problem of driverless technology is the safety problem after going on the road. Installing a remote monitoring system on the driverless smart car can effectively avoid the occurrence of safety accidents. In this paper, a four-wheel drive smart car is used to simulate the movement of the smart car, and the main control machine is used to monitor the information of the optocoupler sensor, the acceleration sensor and the GPS positioning sensor. The communication between the smart car and the receiving end point is realized through the IOT module, and the position, acceleration and speed information of the driverless smart car are monitored. The IOT module is used to select the MQTT protocol to facilitate the transmission of information and the control of the smart car. This method has the advantages of low cost and relatively reliable technology.Experimental verification shows that the system can wirelessly monitor smart cars in a fixed area. In a good network environment, information reception is more timely, with strong security and reliability.
