Wireless sleep control system and method

Abstract

The invention discloses a wireless sleep control system and method. The system comprises a control parameter acquisition device, a sleep wake-up control device and a controlled device. According to the invention, the method comprises the steps: enabling the control parameter acquisition device to acquire control parameters; enabling the sleep wake-up control device to generate dormancy triggeringinformation and wake-up triggering information according to the control parameters; determining whether a sleep condition or a wake-up condition is met or not by judging the sleep triggering information and the wake-up triggering information; when the sleep condition or the wake-up condition is met, sending a sleep instruction or a wake-up instruction to a controlled device to enable the controlled device to enter a sleep or wake-up working state. According to the invention, the purpose of controlling the other part of wireless sensors powered by the battery to sleep and wake up by utilizing monitoring data of one part of sensors can be realized, and the method is particularly suitable for application scenes needing long-term sleep.

Description

technical field [0001] The invention relates to the technical field of wireless monitoring, in particular to a wireless sleep control system and method for controlling wireless devices, especially wireless sensors, to enter long-term sleep and wake up. Background technique [0002] The structure of the traditional large-scale equipment status monitoring system adopts a two-level structure, that is, it is composed of a status monitoring device and a monitoring host. The status monitoring device and the monitoring host use a wired connection. The status monitoring device, such as a sensor, is used to collect status information. For example, the wind force, wind direction, attitude, etc. of the ship during navigation, the stress, inclination, ambient temperature, humidity, etc. of the mechanical arm of the large coal shearer when mining coal underground, these status information are directly transmitted to the monitoring host through the cable. With the development and applicat...

[0006] Second, when the monitored equipment is running or stopped, the data collected by the sensor cannot be distinguished from the data when the monitored equipment is faulty. For example, when the ship is sailing or stopping, the lighting system on the ship is always on. , so the torque value of the shaft in the lighting power system does not actually change. However, when the ship stops, the torque of the shaft in the lighting power system does not need to be monitored. In this application scenario, the battery-powered wireless The torque monitoring sensor will no longer be suitable for judging whether it needs to go to sleep through the data collected by itself

[0007] Although, in many monitoring systems, related technologies involve triggering by external equipment (such as the Chinese patent application document with publication number CN109040583A) to make battery-powered equipment dormant, this method is not suitable for large-scale distribution network monitoring system

[0008] To sum up, the existing wireless device sleep control method is single, and it cannot realize the sleep wake-up management of wireless devices in the networked monitoring system, such as wireless sensors, for different situations.
