Ultra-remote elevator maintenance monitoring method based on LoRa

Abstract

The invention relates to an ultra-remote elevator maintenance monitoring method based on LoRa. Radio frequency technology is used for acquiring the information of an inspection personnel reaching a designated elevator, and is equivalent to a radio frequency positioning sign-in, and monitors whether the inspection personnel reaches the site or not, and whether an elevator object to be checked is correct or not. The inspection personnel use a portable collection information input device to collect and input various information of the elevator; and after signing, a maintenance table is uploaded:after the face recognition is successful, the maintenance table can only be uploaded, and the strictness of the maintenance process is guaranteed. All information collected by the collection information input device is packaged and sent through a LoRa module arranged in the collection information input device; the LoRa gateway captures the information sent by the LoRa module, and then the receivedinformation is sent to an elevator maintenance control center through the local area network. According to the method, the personnel in-place dimension detection situation can be monitored, the on-site effectiveness input of the dimension detection information is controlled, and meanwhile, the data is transmitted to the maintenance control center through the LoRa, and powerful data support is provided for later maintenance.

Description

technical field [0001] The invention belongs to the technical field of special equipment maintenance and inspection, and in particular relates to a LoRa-based ultra-remote elevator maintenance and monitoring method. Background technique [0002] According to the data released by the General Administration of Quality Supervision, Inspection and Quarantine, the number of new elevators in my country is more than 300,000 units each year. Among the many safety hazards, the most prominent threat to the safety of domestic elevator use is the "aging" crisis. According to statistics, the number of elevators in my country has exceeded 1.63 million units, a considerable part of which were installed in the 1990s and have been used for more than ten years, and some elevators have been used for more than 20 years. However, since the country does not currently stipulate the mandatory scrapping period for elevators, a large number of old elevators are still operating with diseases, which in...
