Based on the functional module, the life cycle management method of the Internet of things embedded equipment comprises the following steps:
step 01, the Internet of things embedded equipment enters a production mode, product detection is carried out on the equipment, and an instruction for switching to a transportation mode is sent when the product passes the detection;
the production mode refers to a mode in which the internet of things embedded equipment is produced in a factory in a large scale. In this mode, the product detection module detects all functions and performance of the product. And (4) performing performance detection on the wireless communication function by using special instruments such as a comprehensive tester and the like. And the production line product detection module reads SIM IC information used by the patch, judges an operator according to MNC and MCC, writes a correct APN on the production line according to the configured corresponding relationship between the operator and the APN, and stores the APN in an EEPROM. Serial port commands need to be developed, and MNC and MCC information of the SIM IC is read; and a serial port instruction needs to be developed, and APN information of the SIM IC can be written into the EEPROM. In this mode, all devices of the internet of things embedded device do not have any service function. The product detection result meets the product qualification standard preset by equipment: the wireless communication function can be normally used, and the wireless communication function is in an unopened state in the current mode; for products meeting the detection standard, the production line tool triggers the sending instruction module to send a mode switching instruction to the next mode.
Step 02, receiving a mode switching instruction, performing encryption authentication on the Internet of things embedded equipment, and then entering a transportation mode;
the transportation mode refers to a mode in which the warehouse logistics are located after the production of the Internet of things embedded equipment is completed. In this mode, the power management module controls all power supplies of the product equipment to be in a power-off state, the whole equipment does not run, and the standby power supply is not started. The wireless communication function management module controls the wireless communication function of the product equipment to be in a closed state and has no service function. In the production mode of the equipment, in order to facilitate production, the information security management module is a unified temporary certificate which is arranged in all product equipment so as to ensure the convenience of production. Before the activation action is completed, the information security management module carries out encryption authentication on the temporary certificate of the Internet of things embedded equipment and the background server, and the information security of data interaction is guaranteed.
Step 03, after equipment installation is carried out on the Internet of things embedded equipment, the equipment enters a to-be-activated mode, a standby power supply is started by a power supply management module, and meanwhile, equipment ID information is configured for the equipment by an information safety management module;
after the equipment is transported to a destination, an engineer installs and powers on the Internet of things embedded equipment, and at the moment, the equipment enters a to-be-activated mode. In the activation mode, an engineer can write a sensor Sequence (SN) or a Serial Number of associated Equipment into the physical network embedded Equipment by using a special tool, an information security management module of the Internet of things embedded Equipment can produce unique terminal device ID information according to the relevant Serial Number and the information such as the Serial Number of the engineer, an SIM IC card Number (ICCID), an Identity code of communication Equipment (IMEI), and the like, and the engineer can read the device ID information by using the special tool and manually upload the device ID information to a background server to complete installation and configuration work.

In the process of activating action, the information security management module transmits the equipment ID information to the background server, the background server generates a corresponding TLS certificate according to the equipment ID information, the TLS certificate is issued to the Internet of things embedded equipment in a wireless communication mode, and the sending instruction module sends an activating instruction to complete equipment activating action. The binding of the TLS certificate and the physical information of the terminal equipment is realized, and the accuracy of data acquisition is ensured. In the process, after the information is bound, the certificate is generated, so that the waste of certificate resources is avoided; the certificate is downloaded to the Internet of things embedded equipment directly from the background server, and compared with the traditional method of writing the certificate by using an off-line tool, the method has higher safety.
Step 05, when the embedded equipment of the internet of things needs to be stopped after being in the activation mode, the embedded equipment of the internet of things enters a product scrapping mode by sending a scrapping instruction, and the wireless communication function of the equipment is completely closed in the mode. When the equipment in a certain activation mode needs to be scrapped, the background server sends a scrapping instruction to the corresponding Internet of things embedded equipment through the instruction sending module to enter a product scrapping mode. After the equipment enters a product scrapping mode, the power supply management module disconnects all power supplies, and the wireless communication function management module closes the wireless communication function of the equipment; and meanwhile, the background server interacts with the telecom operator server to complete the charge settlement of the related number.

Because the SIM IC is not started, the long-time warehouse logistics process can not generate a large amount of monthly telephone number fee.
After the Internet of things embedded equipment is installed, when activation is carried out, firstly, a background server and a telecom operator server are required to interact, and SIM ICs in the corresponding Internet of things embedded equipment are activated according to SIM IC card number information; after the SIM IC is activated, the Internet of things embedded equipment can be connected to a communication operator base station and accessed to the Internet; at the moment, the background server can interact with corresponding embedded equipment of the Internet of things through the wireless communication network of the operator to complete the activation process.
When some equipment needs to be scrapped, the background server sends a scrapping instruction to the corresponding Internet of things embedded equipment to enter a scrapping state, and the wireless communication function of the equipment is closed; and meanwhile, the background server interacts with the telecom operator server to complete the charge settlement of the related number.
The method comprises the steps that the embedded equipment of the Internet of things is in an activation mode, the embedded equipment of the Internet of things comprises three working states of an operation state, a standby state and a silent state, different working states are selected according to the characteristics of different services, and the overall power consumption of the equipment is comprehensively reduced through working state migration.
The operation state is as follows: in the state, all functional modules of the Internet of things embedded equipment normally operate, and the state information of the sensor and the related equipment is collected and reported to the background server; or receiving the instruction of the background server to remotely control the related equipment.
Standby state: in the state, all functional module power supplies of the Internet of things embedded equipment are kept in a starting state, and all modules are dormant; the equipment can be awakened at any time by the wireless communication module, the sensor detection module and the bus communication module.
Silence state: in this state, the physical network embedded type closes the power supply of the wireless communication module, and the sensor detection module and the power supply of the bus communication module keep entering a sleep mode. The equipment can be awakened by the sensor detection module and the bus communication module. In the silent state, the power of the wireless communication module is turned off, so that the overall power consumption is lower than that in the standby state.
The three working state change and migration processes of the internet of things embedded equipment are as follows:
and all services of the Internet of things embedded equipment are finished, the relevant equipment stops working, the Internet of things embedded equipment does not need to acquire relevant information, and the data acquisition service stops. The state change triggering unit judges that the equipment is in a service completion state at the moment, and the triggering state transition path control unit selects a transition path of the equipment from an operation state to a standby state.
The method comprises the steps that related equipment of the embedded equipment of the Internet of things is started to work or abnormal events (abnormal sensor state, abnormal power supply and the like) occur locally, a state change triggering unit judges that the equipment is in a local service requirement triggering event at the moment, a triggering state migration path control unit selects a migration path of the equipment from a standby state or a silent state to an operating state, the embedded equipment of the Internet of things enters the operating state, and data acquisition service or alarm service is executed.
The background server initiates a remote control instruction to the Internet of things embedded equipment through a wireless communication function by operation of related personnel. The state change triggering unit judges that the equipment is in a background remote service requirement triggering event at the moment, the triggering state transition path control unit selects a transition path of the equipment from a standby state to an operating state, the Internet of things embedded equipment enters the operating state, and the remote control service is executed.
