The key and difficult points of the system are the processing of the NB-IOT network and the processing of the motor matching mechanism, and the following is a preferred embodiment for solving the secondary technical problem:
firstly, a data transmission solution of a platform is introduced:
as shown in fig. 2, OMA is an international organization, because of the rise of the internet of things, OMA proposes LWM2M protocol on the basis of the conventional OMA-DM protocol. This protocol is based on the COAP protocol, which is based on the UDP protocol.
lwm2m consists of 3 devices (otherwise known as logical entities), client devices, bootstrap servers, work servers:
LWM2M Server: a work server;
LWM2M client: the server is responsible for executing the commands of the server and reporting the execution results;
LWM2M Bootstrap server: the boot server is responsible for configuring the LWM2M client;
can be simply understood as: firstly, a device such as a computer is an LWM2M client device, secondly, a boot Server boottrap Server is needed, which is used for configuring your computer, and a Server work Server. Therefore, in the protocol, the computer first asks the guidance server, which work server should be connected (as shown in fig. 3), and then connects the work servers, which is similar to stone-throwing.

communication interface between client and boot server (as shown in fig. 4): bootstrap server configures Clinet-for example, URL address of LWM2M server through this interface;
registration interface between client and work server (as shown in fig. 5): this interface lets the client register with the server and informs the server of the capabilities supported by the client (in short which resources and objects are supported;
device management interface between client and work server (as shown in fig. 6): this is the most dominant traffic interface. The LWM2M Server sends an instruction to the Client and responds;
reporting interface between client and working server (as shown in fig. 7): this interface is LWM2M Client reporting its resource information, such as sensor temperature. The reporting mode may be event triggering or periodic.
The following describes the technical scheme of the software layer in the embodiment:
aiming at the relative complexity of the system, the data processing among various interfaces among a plurality of modules is involved, and the software design difficulty is relatively high. In order to simplify the design difficulty of system software and increase the stability of a software system, a real-time operating system FreeRTOS is selected.
As shown in fig. 8, the software layer is burned in the storage module and connected to the data layer, and includes a serial protocol processing module, a reclosing module, and a metering processing module;

After the task is triggered, feeding the dog, and for the timed awakening task, adding 1 to a count, wherein the count needs to be cleared in the task. If a certain count is greater than a certain value, the task is possibly halted, and the task is forcibly restarted. For the tasks triggered by the messages, a timing mark is triggered when the tasks start to be processed, the tasks start to be timed are monitored, when the tasks are processed, the marks and the counts need to be cleared, when a certain count is larger than a certain value, the task is indicated to be possibly halted, and the task is forcibly restarted. Through the processing, normal operation of each task after restarting is ensured after each task is halted.

Further, the software layer comprises an OTA module, and the OTA module is used for calling the device management interface to receive and execute the upgrade instruction from the working server. The detailed logic is as follows: the platform loads an upgrade package according to rules, and then the platform issues an instruction which can start upgrading to the specified equipment; after the appointed equipment receives the starting instruction, the equipment issues an instruction to obtain the appointed upgrade sub-package after sub-package, the same sub-package can be repeatedly obtained, the sub-package with the appointed number can be obtained, the sub-package is obtained according to the sequence under the normal condition, and if the platform does not reply for more than 30 seconds, the upgrade is determined to fail; after the upgrade package is completely acquired, the equipment issues an instruction, informs a platform result and requests the next action; at this point the platform issues a command to perform the upgrade or abort the upgrade, and again within 30 seconds the platform will abort the upgrade without replying to the device. The remote upgrade flow is shown in fig. 11.

After data is sent, allowing to receive the message, carrying out synchronization through the message, and analyzing if the message is received; and if the message is not received after time-out, the message is forbidden to be received, the error times are counted, and the next equipment operation is carried out.
Further, the software layer comprises a network transceiver module, and the network transceiver module is used for forwarding the event message and monitoring and maintaining the network state based on heartbeat implementation. The specific logic is as follows: processing network transceiving data, processing a message once at a timing of 100ms, and if no message exists, performing network monitoring and maintenance work, and processing the data in a state machine mode, heartbeat, a registration frame and the like.
