Signal assessment and improvement system of remote monitoring device and control method

Abstract

The invention discloses a signal assessment and improvement system of a remote monitoring device and a control method. The system comprises an elevator control system used for controlling elevator running, the remote monitoring device used for receiving and transmitting elevator running information, a signal base station for transferring data and a cloud server; and the remote monitoring device comprises a data processing module and an antenna module, and the antenna module comprises an antenna and a signal strength detection device. During installation or debugging of the remote monitoring device, the remote monitoring device continuously transmits testing data packages to the cloud server through the signal base station, the cloud server responds the remote monitoring device and feeds back testing data, the remote monitoring device receives the fed-back data and conducts statistics on signal reliability at the position, and the best antenna placing position at the current environment is comprehensively operated in cooperation with signal strength data fed back by the signal strength detection device. Meanwhile, when an elevator runs, telecommunication abnormal failures are fed back when it is detected that the current signal reliability is too poor.

Description

technical field [0001] The invention relates to the research field of elevator control, in particular to a signal evaluation and improvement system and control method of a remote monitoring device. Background technique [0002] In the context of the current increasing use of elevators, the number of failures is also increasing. As the only mode of transportation in modern buildings, its attention is also rising rapidly. Therefore, once there is a failure, it will definitely cause a wide range of problems. attention, and even trigger a company's public relations crisis. [0003] Therefore, not only the real-time control and quick response of elevator operation, but also the monitoring and collection of elevator manufacturers' own product operation data, all require us to improve the remote monitoring scope and reliability of elevator products. [0004] Therefore, there are many remote monitoring products based on different communication methods on the market, such as remote ...

AI Technical Summary

Problems solved by technology

[0005] However, because wireless communication itself has the problem of signal reliability, although many remote monitoring devices and systems have appeared, they are all based on existing communication technology for later development and application, and do not take into account remote monitoring. The basic problem of the monitoring device is the reliability of the signal, and in some backward or remote places, the signal strength may be very poor; in some places with many interference factors, the signal packet loss rate may be high; in some In the older technology, the data transmission speed may be very low, which cannot meet the existing data volume transmission requirements. It is impossible to quickly locate and automatically analyze communication faults, and often requires staff to arrive at the scene for inspection, debugging, replacement and other operations
