Installation method of local area network in elevator Internet of Things

Abstract

The invention relates to the field of elevator internets of things, and discloses a method for installing a local area network in an elevator internet of things. The method includes the steps of installing a gateway in a control cabinet in an elevator machine room of a central building; installing nodes at the positions in other control cabinets, except the control cabinet where the gateway is located, in the elevator machine room of the central building respectively, wherein the network signal receiving strength of the positions is equal to the first preset strength; installing a first-stage relay at the position on the top of the elevator machine room of the central building, wherein the network signal receiving strength of the position is equal to the second preset strength; installing N-stage relays at the positions on the tops of elevator machine rooms of other buildings, except the central building, in a monitored area of the elevator internet of things respectively, wherein the network signal receiving strength of the positions is equal to the third preset strength; installing nodes at the positions in the control cabinets in the elevator machine rooms of other buildings respectively, wherein the network signal receiving strength of the positions is equal to the fourth preset strength. Compared with the prior art, the optimal local area network is formed by the nodes, the gateway and the relays.

Description

technical field [0001] The invention relates to the field of the elevator Internet of Things, in particular to a method for installing a local area network in the elevator Internet of Things. Background technique [0002] In the prior art, in the elevator Internet of Things, an elevator generally needs to install a node, and a gateway is installed in the center of a community. When the distance between the node and the gateway is long, a repeater is installed so that the signal of the node can pass through the center. The repeater can be transmitted to the gateway, or the signal of the gateway can be transmitted to the node through the repeater; but at present, the installation positions of nodes, gateways and repeaters are generally determined according to the experience of technicians, for example, the gateway is installed in the center of the community The location, the repeater is installed between the node and the gateway, and the number of repeaters between the node an...

[0002] In the prior art, in the elevator Internet of Things, an elevator generally needs to install a node, and a gateway is installed in the center of a community. When the distance between the node and the gateway is long, a repeater is installed so that the signal of the node can pass through the center. The repeater can be transmitted to the gateway, or the signal of the gateway can be transmitted to the node through the repeater; but at present, the installation positions of nodes, gateways and repeaters are generally determined according to the experience of technicians, for example, the gateway is installed in the center of the community The location, the repeater is installed between the node and the gateway, and the number of repeaters between the node and the gateway is also estimated. The technician believes that the distance between the node and the gateway is too far or the signal is not good. , a repeater will be added between the node and the gateway. Since there is no precise planning and measurement, there is no way to determine where to install the repeater to achieve the best signal transmission effect with the least repeater. It is easy There are too many repeaters in some areas, resulting in waste of resources; and too few repeaters in other areas, resulting in poor signal transmission. The same is true for gateways and nodes. The existing technology determines the installation location based on experience. Form an optimal local area network between nodes, gateways and repeaters
