According to the electric bicycle digital identity information and multi-video identification data matching method provided by the invention, one or more key point locations are set in the monitoring target area, the radio frequency identification equipment is set at each key point location, the radio frequency identification equipment does not need to be installed at other point locations, and only a low-cost pure video camera needs to be installed to capture video images, so that the monitoring efficiency is greatly improved. The digital identity information of the electric bicycle in the monitoring target area can be effectively identified by sharing the data acquired by the approval reading equipment of the key point location, so that the implementation cost of the scheme is greatly reduced.

This application provides a table entry management method and apparatus, relating to the field of communication technology and applied to network devices. The method includes: setting a hardware MAC address table to prevent aging; executing a software table entry polling task to poll each storage location of the software MAC address table; the software table entry polling task performing a logical AND operation between the authentication type of the first software MAC address table entry at the polled storage location and an aging filter bitmap mask; wherein the aging filter parameter bit of the aging filter bitmap mask is set to a binary value of 1; determining that the corresponding bit of the aging filter parameter bit in the logical AND operation result has a binary value of 1, identifying that the first software MAC address table entry matches the aging filter parameter; and polling the next storage location of the software MAC address table to skip the aging deletion process of the first software MAC address table entry. This solution can solve the problem of user terminals being online, but hardware MAC address table entries being aged, thus improving the user's internet experience.

The invention relates to the technical field of Internet of Things smart home, in particular to a device MQTT secure access method and device under a smart home platform and a storage medium. According to the method, an MQTT server and data are configured on a smart home platform, a to-be-added device initiates an adding request to the smart home platform to obtain MQTT server information, and if the request is added to a setting rule of the smart home platform under an MQTT protocol through a user-defined terminal device, the to-be-added device is added to the smart home platform. If yes, the smart home platform returns a preset number of MQTT server information to the to-be-added device; and the to-be-added device is added into the MQTT server according to the MQTT server information, and after the MQTT server information succeeds, the smart home platform stores the information of the MQTT connection of the added device, and counts the number of connections of different MQTT servers. According to the method provided by the invention, the problems that the information of the MQTT server is not easy to leak and the MQTT server after information leakage cannot be randomly connected are solved, the problem of load balancing of different MQTT servers is also solved, and the situation that the connection pressure of a certain MQTT server is too large is avoided.
