Method and system for limiting connection number and flow of Internet of Things equipment

The invention relates to a method and system for limiting the connection number and flow of Internet of Things equipment, and the method comprises the steps: the Internet of Things equipment sends an online message, and requests to establish connection; verifying a pod connection number through a Lua script, and verifying a tenant connection number; the Internet of Things device is online and sends a device message; the number of pod equipment messages is controlled through a full-current limiter, and the number of sent equipment messages is controlled through an equipment current limiter; and putting the equipment message into a message queue to be used by the equipment. The connection number is judged through Lua, a request and response do not need to be transmitted through a network, network delay and load are reduced, flow is limited through a filter, the stability of the whole system is ensured through a full current limiter, excessive load of the system is prevented, individual control over individual e
