M2M is the abbreviation of Machine-to-Machine/Man, which is a kind of networked application and service with the intelligent interaction of Machine terminals as the core. It will make the object realize intelligent control. M2M technology involves five important technical parts: machine, M2M hardware, communication network, middleware, and application. Based on the cloud computing platform and intelligent network, it can make decisions according to the data obtained by the sensor network, and change the behavior of the object for control and feedback. Take the intelligent parking lot as an example, when the vehicle enters or leaves the antenna communication area, the antenna carries out two-way data exchange with the electronic identification card by means of microwave communication, reads the relevant information of the vehicle from the electronic car card, reads the relevant information of the driver on the driver card, automatically recognizes the electronic car card and the driver card, and judges whether the car card is valid and the driver card is legitimate. Check the vehicle license plate number and driver information corresponding to the electronic vehicle card and driver card displayed by the lane control computer; The lane control computer automatically stores the information about the passing time, the vehicle and the driver into the database. The lane control computer judges whether the card is normal, unauthorized, no card or illegal according to the data read, and makes corresponding responses and prompts. In addition, the elderly at home wear a watch embedded with smart sensors, and children in other places can check whether their parents' blood pressure and heartbeat are stable through their mobile phones at any time. When the master goes to work in the intelligent house, the sensor automatically shuts off the water, electricity and doors and Windows, and sends a message to the master's mobile phone regularly to report the security situation
