When the front-end control 201 sends a terminal control command, the device management module 204 analyzes the command, then sends data to other modules, receives feedback data from other modules, and sends the feedback data to the front-end control 201 for display.
When the communication management module 206 receives the data from the node 203, the communication management module 206 sends the data to the input buffer 205. When there is data in the output buffer 207, the communication management module 206 requests the data with higher priority from the output buffer 207, processes the data with priority, parses the data, and sends the parsed data to the node 203. When the communication management module 206 receives the terminal control command sent from the device management module 204, the communication management module 206 configures parameters of the communication mode and sends feedback data to the device management module 204.

The device number is a unique number assigned by the device management module at the time of registration. The node list is used for storing node information used by the equipment scheme, and comprises node names, node numbers, communication methods, priorities, data frame protocols and operation task lists. The node number is a unique number assigned by the device management module at the time of registration. The data frame protocol is used to parse the data frame sent by the node.

In the figure, the running task list is ordered according to the priorities, a plurality of priority queues are maintained, each priority queue is executed according to the order, and meanwhile, according to the average running time of the tasks, the task management module dynamically adjusts the priorities of the tasks so as to ensure that the tasks can be executed more uniformly. When the task running time in the running task list is too long or the waiting needs to be paused, the task is transferred to the waiting task list in the figure, and when the waiting time is over or the waiting time is paused, the task in the waiting task list is transferred to the running task list according to the priority to continue to be executed. After the task management module executes the task, the feedback information is sent to the equipment management module, and the tagged data is sent to the output buffer area.
Referring to fig. 7A, fig. 7A is a schematic diagram of a data frame structure for communication between a communication management module and a node in an intermediate layer according to an embodiment of the present invention.

After receiving the data from the node, the communication management module firstly checks the frame header and the check code, matches and analyzes the data according to the data frame protocol registered to the communication management module after the data is correct, and then sends the data to the input buffer area in a labeled manner, and meanwhile, if the node needs feedback, feedback information is sent to the node. When the output buffer area has data, the data can be analyzed according to the label content of the data of the output buffer area, so that the data can be correctly sent to the corresponding node. The label information in the figure is used for providing information necessary for a communication mode, for example, when the TCP/IP protocol is used for communication, information such as IP and port numbers of a server side and a client side is needed, and for example, when the Bluetooth communication is used, information such as UUID is needed. In the figure, the priority is used for providing the processing priority of the data, and the data with high priority is processed preferentially, wherein the priority is obtained by the communication management module through data frame protocol analysis.
Fig. 8 is a schematic diagram of a data frame structure of sharing data between a plurality of control terminals through a cloud server according to an embodiment of the present invention.

First, the control terminal sends a command frame 801 in the graph to the cloud server, and the cloud server determines a manner of receiving data according to the command number and the command data. The control terminal needs to send a registration command when sending data to the cloud server for the first time, and the cloud server returns the number of the control terminal; if the control terminal is switched from the offline mode to the online mode, the control terminal checks the number of the control terminal with the cloud server, and if the number is occupied, the cloud server reissues the number. The control terminal may then choose whether to send all or part of the data. The control terminal transmits all data, firstly transmits a control terminal information data frame 802 in the figure, receives a device information data frame 803 according to the number of devices in the figure, and then receives a node information data frame 804 according to the number of nodes in the figure until the data reception is completed. When the control terminal sends an update command to the cloud server, only the data frame update data of part of the steps is received. The cloud server stores a time stamp and calculates an integral MD5 value for the data sent to the cloud server each time so as to judge whether the data needs to be updated, and when a plurality of control terminals are connected with the cloud server, the control terminals can apply for updating the data of other control terminals or send commands to the cloud terminals periodically so as to ensure the data sharing and cooperative work of the plurality of control terminals.
