the device management module is used for setting a target access port of the device as a container port of the first access container when the port distribution module does not distribute the container port for the data access and command issuing container distributed for the device, so that the device is accessed into the first access container through the target access port, and changing the target access port of the device as the container port of the distributed data access and command issuing container when the port distribution module distributes the container port for the data access and command issuing container distributed for the device by the automatic capacity expansion and first access management module, so that the device is accessed into the distributed data access and command issuing container through the target access port.
4. The internet of things platform based on containerization technology of claim 3, wherein the data access and command issuing container as the non-first-time access container is further configured to load device information of the device accessed to the container from the device master database according to the mapping relationship before receiving data reported by the device accessed to the container or receiving a command issued by an upper-layer application;
the data access and command issuing container as the first access container is also used for acquiring the equipment information of the newly registered equipment from the equipment management module before receiving the data reported by the equipment accessed to the container or receiving the command issued by the upper application, and removing the loaded equipment information of the equipment after the equipment management module changes and sets the destination access port of the equipment as the container port of the allocated data access and command issuing container.
5. The internet of things platform based on containerization technology of claim 1, wherein the automatic expansion and initial access management module is configured to allocate a data access and command issuing container to the device according to the acquired device information and a preset allocation rule, and specifically includes:
and the automatic capacity expansion and first access management module is used for distributing a data access and command issuing container for the equipment according to the equipment information and the residual accessible equipment capacity of each data access and command issuing container.
6. The internet of things platform based on containerization technology of claim 5, wherein the automatic capacity expansion and initial access management module is configured to allocate a data access and command issue container to the device according to the device information and a remaining accessible device capacity of each data access and command issue container, and specifically comprises:
the automatic capacity expansion and first access management module is used for distributing the same data access and command issuing container for the equipment with the same production source and/or the same data transmission protocol and/or the same user according to the equipment information and the residual accessible equipment capacity of each data access and command issuing container.
7. The platform of the internet of things based on the containerization technology of claim 1, wherein the data access and command issuing container comprises an adapter and message queue middleware;
the adapter is used for receiving data reported by equipment, uploading the data to the message queue middleware, acquiring a command issued by an upper application from the message queue middleware, and transmitting the command to the equipment;
the message queue middleware comprises a data queue and a command queue;
the data queue is used for receiving and storing the data uploaded by the adapter;
and the command queue is used for receiving and storing commands issued by the upper application.
8. The platform of the internet of things based on the containerization technology of claim 7, wherein the message queue middleware further comprises a rule queue and/or an event queue and/or a management queue;
the rule queue is used for receiving and storing the data uploaded by the adapter and needing to be subjected to rule calculation according to a preset calculation rule;
the event queue is used for receiving and storing alarm events sent out when the data is subjected to rule calculation according to preset calculation rules and is abnormal;
the management queue is used for receiving and storing the equipment information of the registered equipment and removing the equipment information of the logged-out equipment.
9. The Internet of things platform based on containerization technology of any one of claims 2-8, wherein the container port comprises a container ip and a port number.
10. The platform of the internet of things based on the containerization technology of claims 1-8, wherein the device information comprises a device class, a device unique code, a device model number, and a device protocol.
