Wireless sensor management method, device and system

Abstract

This application discloses a wireless sensor management method, device and communication system. The communication system includes a site management unit, a management node and a wireless sensor; the wireless sensor sends a connection request to the management node when it is in the awake state; the management node queries whether its local cache has the third A message; the first message is a message from the site management unit received by the management node when the wireless sensor is in a dormant state; the management node sends a response to the wireless sensor according to the result of the query; the result of the query is that the first message is pre-cached locally When, the response carries the first message; when the query result is that the first message is not cached locally, the response indicates that the management node does not cache the first message, and the wireless sensor quickly transitions from the wake-up state to sleep after receiving the response. state. Implementing the embodiments of the present invention can extend the battery life of wireless sensors and meet the needs of large-scale wireless sensor applications in access-side sites.

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...
