Communication system and data sending method of elevator internet of things

Abstract

The invention relates to the field of elevator internet of things and discloses a communication system of the elevator internet of things and a data sending method. The system comprises elevator controllers, nodes, network equipment and a server of the internet of things, and further comprises a gateway, wherein each node is connected with one elevator controller and is in wireless connection with the gateway; the gateway is connected with the network equipment and the server of the internet of things in sequence; each node sends elevator operating data of the elevator controller connected with the node to the gateway in a wireless mode, and the gateway sends the received elevator operating data to the server of the internet of things through the network equipment. Compared with the prior art, the multiple nodes are in communication with the server of the internet of things through one gateway, loads of the server of the internet of things can be lowered remarkably, network cost of the whole communication system is lowered, and an elevator can have access to the internet conveniently and rapidly.

Description

technical field [0001] The invention relates to the field of the elevator Internet of Things, in particular to a communication system and a data sending method of the elevator Internet of Things. Background technique [0002] The existing elevator Internet of Things adopts a structure in which one elevator controller corresponds to one node, and each node communicates with the Internet of Things server through at least one repeater and a set of network access equipment, such as figure 1 As shown in the figure, M represents the total number of nodes, and M is an integer greater than or equal to 1. The cost of this structure is too high, and the expansion ability is limited. Every time an elevator is added, another set of network access equipment is required, and the system cost is relatively high; If there are too many elevator controllers, this communication method will increase the load on the IoT server sharply; in addition, since the operating data of each elevator contr...

Problems solved by technology

The cost of this structure is too high, and the expansion ability is limited. Every time an elevator is added, another set of network access equipment is required, and the system cost is relatively high; If there are too many elevator controllers, this communication method will increase the load on the IoT server sharply; in addition, since the operating data of each elevator controller is transmitted separately, the distance between the node and the IoT server The amount of data transmission is large, and the cost of network traffic will also increase accordingly; in addition, the elevator Internet of Things technology in the existing technology integrates collection and long-distance wireless transmission functions, and the installation site of each node needs to consider long-distance wireless signals. Such as GPRS (General Packer Radio Service, General Packet Radio Service) signal, if the signal is not covered, the network access effect of this elevator will be very poor
