Embodiment Construction

[0016] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described.

[0017] First of all, the general sensor node is composed of two parts: the sensing module and the communication module, and the sensing module and the communication module are connected by a common interface, such as figure 1 shown.

[0018] The sensing module is mainly responsible for collecting data in various application environments, and connecting with the communication module through a common interface, so as to be applied to sensing equipment in different industries (such as environmental monitoring, medical and health, military, etc.), and can be used by equipment in different industries provided by the manufacturer, regardless of its communication function.

[0019] The communication module is mainly responsible for receiving the data transmitted by the sensor device from the general interface, and networking, so ...

Abstract

The invention provides an event adaptive sensor node. A mode of separation of a sensing module and a communication module is adopted, and a data collecting function and a communication function are arranged independently so as to solve problems of professional requirements of sensing devices facing complex environments and applicability and compatibility requirements in communication networking. In addition, a self-adaption sleep mechanism of the communication module is provided, and wakeup time of the communication module is set through prediction of occurrence time of a next event so as to achieve automatic wakeup after the sleep. The sleep mechanism reduces energy consumption of the communication module, and prolongs service life of the whole sensor node.

Description

technical field [0001] The invention relates to the technical fields of wireless sensor networks and the Internet of Things, in particular to an event-adaptive wireless sensor node energy-saving dormancy method. Background technique [0002] With the development of wireless sensor nodes and network technology, the application range of wireless sensors is becoming wider and wider, and their specialization is becoming stronger and stronger. The emergence of various professional sensor nodes has also brought challenges to the networking of wireless sensor networks: a large number of professional sensor nodes (such as rainfall sensors in environmental monitoring, pH value monitors, blood pressure in medical environments, ECG sensors, etc. ), which need to be provided by professional sensor equipment manufacturers; and its communication and networking capabilities vary with the change of application requirements and environment, and sensor equipment manufacturers cannot provide c...
