Problems solved by technology
[0003] In the existing technology, the spatial similarity of node sensing data is used, that is, the sensing data sensed by adjacent spatial nodes is similar, based on the comparison of sensing data between adjacent nodes, the state of the node under test is determined, and then the node is tested The state is diffused and transmitted to other nodes, thereby monitoring all nodes of the wireless sensor network. The monitoring efficiency of the existing technology is not high enough

The invention provides a monitoring method for a wireless sensor network, and the method comprises the steps that a concentrator transmits a first triggering signal to a plurality of wireless sensor nodes through employing a first time length as a period, wherein the first trigger signal is used for triggering a plurality of wireless sensor nodes to respectively upload acquired data to a concentrator according to the sending time of the first trigger signal and the uploading delay of the wireless sensor nodes; if the acquired data which do not meet the preset standard condition exists in the acquired data uploaded by the plurality of wireless sensor nodes, the concentrator sends a second trigger signal to the plurality of wireless sensor nodes by taking a second time length as a period; wherein the second trigger signal is used for triggering the plurality of wireless sensor nodes to adjust the uploading delay of the wireless sensor nodes, and uploading the collected data to the concentrator according to the adjusted uploading delay and the sending time of the second trigger signal. By implementing the embodiment of the invention, the monitoring efficiency of the wireless sensor network can be effectively improved.
Description
technical field [0001] The present application relates to the technical field of wireless sensor networks, in particular to a monitoring method and related equipment for a wireless sensor network. Background technique [0002] Wireless sensor networks are used in various fields, such as military fields, industrial fields, agricultural fields, and household fields. Wireless sensors are composed of a large number of low-cost micro-sensors and microprocessors, which have the functions of collecting, processing and transmitting data. A large number of wireless sensors form the nodes of the wireless sensor network. Due to the huge number of nodes in the wireless sensor network, the application environment It is complex and changeable, so it is necessary to effectively monitor the data collected by wireless sensor nodes, that is, the wireless sensor network. [0003] In the existing technology, the spatial similarity of node sensing data is used, that is, the sensing data sensed ...
