A device state monitoring method and device

Abstract

The present application provides a device state monitoring method and device, including: reading the full state data of the device according to the preset cache cycle, and caching and generating the full state data of the first cache device; updating the full state data of the first cache device according to the preset cache times , generate the full status data of the second cache device; report the full status data of the second cache device based on NB-IoT according to the reporting instruction. The device status monitoring method and device provided in this application, when the reporting instruction is reached or received, will report the generated second cache device full status data through NB‑IoT, effectively controlling the acquisition and reporting of the full status data of the device , so that NB-IoT technology can be adapted to the monitoring of full-state data of large-scale equipment such as air-conditioning equipment, and the technical advantages of wide-coverage and large-connection of NB-IoT technology are applied to the business scenarios of state collection and fault diagnosis of large-scale equipment , which is helpful for the monitoring of equipment status of large equipment.

Description

technical field [0001] The present application relates to the technical field of equipment monitoring, in particular to a method and device for monitoring equipment status. Background technique [0002] NB-IoT (Narrow Band Internet of Things, narrowband cellular Internet of Things), is a technical standard defined by the 3GPP standardization organization. It is a narrowband radio frequency technology specially designed for the Internet of Things. power consumption, low cost and high stability. However, according to the technical standards of NB-IoT, NB-IoT technology has narrow bandwidth and low transmission rate, and is suitable for low-frequency connections (operators recommend 20,000 times / year) and small data volume reporting (operators recommend 512B / time). In business scenarios, it is currently mostly used for small devices with simple operating status attributes and small data volumes such as electric meters, water meters, and firefighting equipment. [0003] The st...

AI Technical Summary

Problems solved by technology

[0004] It can be seen that although NB-IoT technology has many advantages, it cannot be applied to the monitoring of large-scale equipment such as air-conditioning equipment because it needs to transmit a large amount of data every time the equipment status is reported in the process of monitoring large-scale equipment such as air-conditioning equipment.
