[0002] At present, the Industrial Internet of Things has ushered in a new era of integration and development with traditional industries. Various industrial Internet of Things application cases have emerged in related industries, which has also laid a solid foundation for the widespread application of the Industrial Internet of Things. In the Industrial Internet of Things environment, the ubiquitous connectivity of infrastructure such as smart sensors and smart manufacturing equipment is the premise for the deployment and application of the Industrial Internet of Things. However, due to the large number of industrial equipment manufacturers and the different communication standards adopted by each manufacturer, there are a large number of communication networks with different network architectures and transmission protocols in the industrial field, which makes it difficult to effectively solve the problem of information islands in complex heterogeneous networks. At the same time, industrial Internet of Things devices will generate a large amount of data during operation. When industrial resources are connected to each other or to the Internet, facing the transmission of massive data and the increasing demand for industrial services, the industrial network has poor ability to distinguish services for data with different delay tolerances, especially for high-delay sensitive data.

[0016] Embodiment 1: Figure 1 This is a flow chart of a communication analysis method based on the Internet of Things provided in Embodiment 1 of the present invention. This embodiment can be applied to an industrial Internet of Things communication analysis system. The method can be executed by a communication analysis system based on the Internet of Things provided in an embodiment of the present invention. The system is composed of multiple software and hardware modules, such as Figure 1 As shown, the method specifically comprises the following steps: S101. Carry out communication structure management of industrial Internet of Things communication analysis system; Exemplarily, in an embodiment of the present invention, the network communication architecture of the intelligent production line of the industrial Internet of Things communication analysis system is divided into four parts, namely, from the bottom layer to the upper layer, the industrial field equipment layer, the data perception layer, the communication gateway layer and the application management layer, so that each layer transmits data according to the OPC UA protocol to ensure efficient transmission of equipment data; in this step, the data perception layer includes OPC UA communication, data classifier, actuator and wireless transceiver integrated in the production line equipment, which provides the system with functions such as data acquisition and signal transmission, and can uniformly collect alarm information, equipment status information and actual processing status information in equipment such as PLC, servo motor and robotic arm, and send them to the upper layer of the system for processing, and realize the connection and communication between the Internet application and the underlying wireless sensor network; the communication gateway layer completes the collection and reception of the data perception layer equipment information by accessing the address space of the embedded OPC UA server in the industrial equipment; the application management layer is composed of various application-level systems for managing the intelligent production line equipment, and the system is uniformly managed through the collected data, providing functions such as sensing the operating status of the equipment, predicting the probability of failure and preliminarily diagnosing the cause of the failure, and at the same time, it can transmit control information to the set equipment to realize real-time control of the production line device.

[0017] S102. Perform model management and priority control on the industrial Internet of Things communication analysis system; Exemplarily, in an embodiment of the present invention, the industrial wireless network model of OPC UA is optimized and managed, and hardware devices that support low-power protocols are used as the underlying basic communication facilities, so that the data link layer adopts a time slot and channel hopping (TSCH)-based scheme to dynamically allocate and schedule time slots according to the network topology and traffic load of each node, so as to achieve efficient allocation of time slots; in this step, the network layer in the control model adopts centralized control graph routing to improve network transmission efficiency, the transport layer uses the TCP protocol to transmit data, and provides data security transmission services based on the OPC UA security model, and the application layer uses the OPC UA protocol to complete data collection and centralized session management. The various layers of the model work together to complete the wireless communication tasks of the equipment in the intelligent production line system.

[0018] After completing the optimization management of the OPC UA industrial wireless network model, the time slots are scheduled according to the network topology and traffic load of each node, and the underlying device data and sensor data are collected to the wireless gateway and stored in a classified manner.

Then, the devices in the list to be allocated are sorted according to the amount of data waiting to be sent in the queue of the device node, and the queue sequence of each node is redefined from large to small according to the queue data cache amount. In this step, when designing a single-cycle time slot scheduling table, time slots are allocated preferentially to nodes with larger loads in the network to ensure priority allocation and transmission of high-load nodes in the multi-slot frame mode.

[0020] After completing the perception processing of the node status, non-intersecting transmission augmented paths are obtained according to the order analysis of the nodes in the list to be allocated, and the high-load nodes are colored first, and the remaining nodes are divided into a non-interference node group and an interference node group, and the nodes in the non-interference node group and the interference node group are sorted from high to low according to the load, and the first node of the non-interference node group is colored with the same color, so as to complete the iterative analysis and processing, and obtain a link set with the same channel offset in the time slot; in this step, the links in the link set are assigned to the multi-slot scheduling table with the number of channels in the time slot that meets the set requirements, so as to obtain the scheduling plan under the time slot.
