Description

Technical Field

[0001] This invention relates to the field of control and management technology, specifically to a control and management system based on the Internet of Things. Background Technology

[0002] With the continuous maturation of IoT technologies such as sensing technology, the Internet of Things (IoT) has gradually become a hot topic in the industry. The essence of IoT is to integrate basic resources based on communication networks and combined with technologies such as wireless sensing. After an IoT system has been in use for a period of time, when the original terminal functions can no longer meet user needs, updates and maintenance become cumbersome. Traditional manual on-site operation can no longer meet the demands of today's large number of devices distributed across complex locations. Remotely sending programs to reuse existing terminal devices and enabling reconfigurable functions for different types of terminals to cope with complex application environments is an inevitable development trend of IoT. However, with the continuous development of IoT, the number of reconfigurable IoT devices is also increasing, along with the massive growth in the number and versions of program packages. This leads to uneven resource utilization across cluster nodes, slow computation on heavily loaded nodes, and excessively long client response times, seriously affecting the application and development of IoT technology. Therefore, it is essential to design an efficient, efficient, and highly practical IoT-based control and management system. Summary of the Invention

They are used in conjunction with embodiments of the invention to explain the invention and do not constitute a limitation thereof. In the drawings: Figure 1 This is a flowchart of a control and management method based on the Internet of Things provided in Embodiment 1 of the present invention; Figure 2 This is a module configuration diagram of a control and management system based on the Internet of Things provided in Embodiment 2 of the present invention. Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Example 1: Figure 1 This is a flowchart illustrating a control and management method based on the Internet of Things (IoT) provided in Embodiment 1 of the present invention. This embodiment can be applied to a control and management system. The method can be executed by an IoT-based control and management system provided in this embodiment, which consists of multiple hardware and software modules, such as... Figure 1 As shown, the method specifically includes the following steps: S101. Perform file cache control and management for the Internet of Things; For example, in this embodiment of the invention, after an IoT file is accessed, it is cached and stored according to its access status data. Although IoT caching can improve the performance of accessing hot data, there are synchronization and cache hit problems. Therefore, this step manages the cache of the accessed file. Specifically, when a file is accessed for the first time, the access record queue initializes the file's index information and sets the file's access count to 1. If it is not the first access, the access count is incremented by one, and the file information is moved to the front of the queue to facilitate subsequent index deletion. When the access count of a file reaches the set threshold, the file is cached. When the index is hit, the cache queue is also reordered according to time. When the cache space is insufficient, the data at the tail of the queue is removed. Through this step, the cache management of IoT file information can be made more efficient and accurate, indirectly making the operation of the IoT system smoother and more stable.

[0018] After completing the cache management of IoT files, the cache area for file caching is managed and controlled. In this step, the relevant parameters of the cache area are managed through the cache area configuration file, and a scheduled task is set to periodically persist cache information to ensure reliability. At the same time, for files whose access count reaches a set threshold, the cache area is periodically cleared after being cached. When a file index is deleted from the cache area, the file access count is reset. When a file is modified, if the caching function is enabled and there is corresponding file data in the cache area, the cache area content is modified first, and mutual exclusion access to the cache area is set. Then, the data in the database is modified to avoid the loss of cache area data after the file information is modified, which may lead to dirty reads.

[0019] S102. File connection processing is performed through the control and management of the file connection pool; For example, in this embodiment of the invention, the connection establishment for user file requests is controlled and managed by controlling and managing the file connection pool. Since each file request by an IoT user requires the establishment of two long connections, and both connections need to be closed after the file request ends, this process of establishing and closing connections twice is not only slow but also resource-intensive. Even if only one file can be processed at a time after the connection is established, multiple connections need to be established when processing multiple files, resulting in significant performance loss to the server. Therefore, this step initializes an idle connection pool and a busy connection pool based on the obtained IoT server address information and multiple initialization parameters of the connection pool, such as rejection policies and connection creation methods. When a connection request is initiated, the idle connection pool is first checked for available idle connections. If one is found, the connection is transferred to the idle connection pool. If no idle connection is found and the maximum number of connections has not been reached, a new connection is created. Otherwise, the process waits. When a connection is broken, the number of existing connections is compared with the configured minimum number of connections. If the minimum number of connections has been exceeded, the excess connections are destroyed. Otherwise, they are returned to the connection pool. This step effectively improves the utilization rate of IoT connection processing resources and greatly enhances the efficiency of connection request processing.

[0020] S103. Analyze and control the dynamic load balancing of IoT devices; For example, in this embodiment of the invention, dynamic load information of IoT devices is collected through a set period. In this step, the nodes in the IoT cluster are controlled to send their own load information to the load balancer in a multicast manner at a set time interval. The load information includes CPU utilization information, memory utilization information and disk I / O utilization information. Through this step, the number of connections of the load balancer can be reduced, the resource occupation of the load balancer can be reduced, and centralized management can reduce the information exchange of the central control node and effectively prevent the central control node from reducing the operating efficiency of the IoT cluster system.

[0021] Based on the real-time load information fed back by each node, the performance of each node in the cluster is re-evaluated and load balancing scheduling management is performed. In this step, since the load status of each node will change significantly after the cluster system has been running for a period of time, the initial weight settings cannot be applied to the system. Therefore, in this step, the connection center node is controlled to send its own load information to the scheduler at regular intervals. Based on the current load status of the server nodes, when there is a request from an IoT terminal, the dynamic load balancer is further controlled to reset the weight of each node according to the load quantification results of each node. The load balancer periodically collects the resource usage of each node, and then analyzes it to obtain the standard deviation B. B is compared with the set threshold Y. If it is less than Y, it means that the current IoT cluster load distribution is relatively reasonable. If it is greater than Y, it means that the current cluster load distribution is uneven. Then, the weights of each node are readjusted and the adjusted weights are assigned to the nodes. Through this process, the weights can be quickly adjusted and the load status can be quantified in real time, making the task allocation more reasonable and the IoT resources more fully utilized.

[0022] By using the interfaces reserved by each actual application project to synchronize terminal information and refresh the information in real time, the synchronization of IoT application terminal information is guaranteed. According to the timed settings of the task, the synchronization information of the terminal is temporarily stored, which effectively alleviates the information storage pressure of the database.

[0023] S104. Perform configuration retransmission processing for the Internet of Things system. For example, in this embodiment of the invention, the control cluster node configuration establishes a connection with the registration center through a TCP long connection, adds the configuration node of the corresponding cluster in the registration center to realize the dynamic expansion of the corresponding cluster, and deletes the configuration node of the corresponding cluster in the registration center to realize the dynamic shrinkage of the cluster.

[0024] When the IoT terminal receives the firmware package, if the verification finds an error in the data packet, it will request the connection center to resend the previous data packet. The connection center will then resend the corresponding data frame according to the received data frame retransmission instruction and retransmission packet number.
