Wireless sensor management method, device and system

Abstract

The application discloses a wireless sensor management method and device, and a communication system. The communication system comprises a site management unit, a management node, and a wireless sensor; the wireless sensor sends a connection request to a management node in an awakening state; the management node queries whether a first message is cached at local in advance; the first message is the message of the site management unit received by the management node when the wireless sensor is in a dormancy state; the management node sends a response to the wireless sensor according to a queryresult; the response carries the first message when the query result is that the first message is cached at the local in advance; the response indicates that the first message is not cached in the management node when the query result is that the first message is not cached at the local in advance, and the wireless sensor quickly switches to the dormancy state from the awakening state after receiving the response. By implementing the management method disclosed by the application, the battery life of the wireless sensor can be prolonged, and the demand that the wireless sensor is applied to anaccess side site in scale is satisfied.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a wireless sensor management method, related equipment and system. Background technique [0002] At present, in the access-side site scenario in the communication field, sensors distributed in the field are usually widely used to collect environmental data, such as collecting environmental temperature and humidity, detecting air quality, detecting fire, detecting oil level, anti-theft detection, controlling lights, etc. Then, according to the pre-specified protocol, the environmental data is sent to the site management unit (Site Management Unit, SMU), and the control instructions of the site management unit are also sent to each sensor via the gateway node. Since the access-side site is generally unattended, in order to keep the sensor working normally for a long time, the site management unit is usually connected to the sensor with a communication cable, an...

AI Technical Summary

Problems solved by technology

[0004] This application provides a wireless sensor management method, device and system, in order to reduce the power consumption of the wireless sensor, prolong the battery life of the wireless sensor, meet the requirements of the battery replacement cycle of the wireless sensor for more than 5 years in the application scenario of the access side station in the communication field, and solve the problem of wireless sensor The problem that it cannot be applied to access-side sites on a large scale can greatly improve the deployment efficiency of access-side sites and reduce deployment costs
