Method for signal coverage in Internet-of-elevators application

Abstract

The invention discloses a method for signal coverage in Internet-of-elevators application and belongs to the field of network coverage. The method comprises the following steps that: S1, in the earlystage of the deployment of an Internet-of-elevators system, original operators are directly multiplexed to deploy signals for elevators with two signal coverage modes of installing directional antennas in elevator shafts and installing antennas in elevator halls on each floor, signal strength testing is carried out according to standards, and the method can be implemented in the elevators when conditions are met; and S2, under the condition of no signal coverage or insufficient coverage signal strength, signal coverage in the shafts is carried out through macro station signals, indoor distribution station signals or a wireless repeater mode and a 4G / 5G routing-to-wireless through-beam mode with original equipment not transformed. According to the method of the invention, the above two network deployment schemes can be adopted; and therefore, the signal dead angle of an Internet-of-elevators system is solved, it is guaranteed that the fault information of each elevator provided with equipment can be uploaded in time, and network deployment is convenient and fast. Compared with a conventional deployment scheme, manpower and material resources are saved.

Description

technical field [0001] The embodiment of the present invention relates to the field of network coverage, in particular to a method for signal coverage in an elevator Internet of Things application. Background technique [0002] With the rapid development and layout of the urban elevator Internet of Things remote emergency rescue and disposal platform, how to ensure that the emergency information is sent to the disposal platform in an emergency in an elevator shaft with no signal or weak signal has become an important issue covered by the elevator wireless network. Key points and difficult points. [0003] Traditional elevator car signal coverage mainly has the following two solutions: [0004] 1. A directional antenna is installed in the elevator shaft [0005] Install a directional antenna or a Yagi antenna in the elevator shaft every 3 floors to cover the shaft, and the feeder needs to be fixed on the wall of the shaft (see Figure 4 ). This installation method needs to...
