Abstract

The embodiment of the invention discloses a method, device and system for inquiring sensor data. The method comprises the following steps: obtaining the data of base station and sensor corresponding to target data; according to the data of base station and sensor, requesting cell broadcast center corresponding to base station to transmit cell broadcast to the intelligent terminal within the coverage area of base station so as to inquire the target data; and receiving the query result of the target data which is obtained by the sensor and is returned from the intelligent terminal. The technical scheme of the invention can be used to ensure that the intelligent terminal in network is used as sink node to collect sensor data, the network deployment cost is reduced and the effect of collecting sensor data instantly can be realized.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a sensor data query method, device and system. Background technique [0002] Advances in technologies such as microelectronics, computing, and wireless communication have promoted the rapid development of low-power multifunctional sensors, enabling them to integrate multiple functions such as information collection, data processing, and wireless communication in a small volume. Wireless sensor network (wireless sensor network, WSN) is composed of a large number of cheap micro-sensor nodes deployed in the detection area, and forms a multi-hop self-organizing network system through wireless communication. Process the information of the perceived objects in the network coverage area and send it to the observer. [0003] A sensor network system usually includes a sensor node (sensor node), a sink node (sink node) and a management node. A large number of sensor nodes are rand...
