The present invention relates to the field of the elevator Internet of things, and discloses a method, system and gateway for communication using a gateway with dual identities. The elevator Internet of Things includes a plurality of local area networks and a server; the communication method in the local area network includes: receiving the server through a network access device The command sent to obtain the operating data of the target elevator controller; extract the address information of the target elevator controller from the command, and compare whether the address information of the target elevator controller is the same as that of the gateway; if the address information of the target elevator controller is the same as The address information of the gateway is the same, and the operation data of the target elevator controller is sent to the server through the network access device; if the address information of the target elevator controller is different from the address information of the gateway, the command is sent to the node correspondingly connected to the target elevator controller. The gateway with dual identities can directly collect the operating data of the elevator controller, and can also forward the command to a node correspondingly connected to the elevator controller.
Description
Technical field [0001] The present invention relates to the field of elevator Internet of Things, in particular to a method, system and gateway for communication using a gateway with dual identities. Background technique [0002] Elevator Internet of Things refers to a network of things connected by connecting fixed elevator systems through sensors and network technology on the basis of the Internet. The network and the elevator system can achieve the effect of interconnection and interaction. The elevator Internet of Things includes elevator controllers, nodes, repeaters, gateways and servers. Nodes are used to collect the operating information of each elevator. That is, nodes can be collectors, and gateways collect all nodes on the same network segment through repeaters. The information of the elevators arriving is aggregated, and the data is transmitted to the service desk through the Internet or mobile communication network technology. [0003] Specifically, when using the exi...
