M2M (MachinetoMachine) is an effective control of equipment through mobile communication, which greatly expands the boundaries of business or creates a more efficient operation mode than the traditional way or creates a completely new service that is completely different from the traditional way. M2M takes the device communication control as the core, and applies the original inefficient or even impossible information transmission to the business to obtain more competitiveness. M2M's business model is currently in the ascendant, mainly including mobile logistics management (M-logisTIcmanagement), mobile payment (M-POS), and mobile monitoring (M-monitoring). M2M is the transfer of data from one terminal to another, that is, the dialogue between the machine and the machine. M2M is not a new concept, it is also a common phenomenon, such as the access control card used for work, supermarket bar code scanning, and then the more popular NFC mobile phone payment. Many years ago, Japan's NEC Corporation had done a lot of publicity and work on M2M, and launched some of the world's leading M2M products, successfully in many fields. "Intelligent" means that the machine "speaks" and gives the machine the ability to sense information, process information and process wirelessly. [1] The machine can be equipped with networking capabilities and remote communication components, extract information, and retrieve the required information from different devices and transmit it to the analysis part. Including wide area network (wireless mobile communication network, satellite communication network, Internet and public telephone network), local area network (Ethernet, wireless LAN, Bluetooth, wifi), personal area network (Zigbee, Sensor network), M2M hardware transmission through the above network The delivery of information to a designated location is at the heart of the M2M technology framework. The M2M gateway completes the transition between different protocols and establishes a bridge between the communication network and the IT system. M2M technology provides a comprehensive solution that integrates data collection, transmission, analysis and business management for all industries, and realizes that business processes and industrial processes are more automated. The main application areas include transportation (logistics management, location and navigation), power (remote meter reading and load monitoring), agriculture (shed monitoring, animal traceability), urban management (elevator monitoring, street lighting control), security (city) And corporate security), environmental protection (pollution monitoring, soil and water testing), enterprises (production monitoring and equipment management) and home (old and child care, intelligent security). The concept of The Internet of Things (The Internet of Things) was introduced in 1999. Its definition is simple: all items are connected to the Internet through information sensing devices such as radio frequency identification for intelligent identification and management. The Internet of Things refers to the integration of various information sensing devices, such as radio frequency identification (RFID) devices, infrared sensors, global positioning systems, laser scanners, etc., with the Internet through a network (mainly mobile networks). A huge network formed, using NEC's slogan, is "network everything."
