Equipment status monitoring method and device

Abstract

The application provides an equipment status monitoring method and a device status monitoring device. The method comprises: reading equipment full status data according to a preset cache cycle, and caching to generate first cache equipment full status data; updating the first cache equipment full status data according to a preset cache number, and generating second cache equipment full status data; and reporting the second cache equipment full status data based on the NB-IoT according to the reporting instruction. The equipment status monitoring method and device provided by the application, when the reporting instruction is reached or received, report the generated second cache equipment full status data through the NB-IoT, and effectively control the acquisition amount and the reportingamount of the equipment full status data, so that the NB-IoT technology may be adapted to the monitoring of the full status data of large-scale equipment such as air-conditioning equipment. The technical advantages of the NB-IoT technology of wide coverage and large connection are applied to the business scenarios of status collection and fault diagnosis of large equipment, which helps to monitorthe equipment status on 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.
