Internet of things entity search method and system

Abstract

The invention discloses an internet-of-things entity searching method and an internet-of-things entity searching system. The method comprises the following steps of: acquiring a time interval, a geographical range and specific query conditions for searching; querying a preset grid database which is in accordance with the time interval and geographical range searching conditions; performing word segmentation on the specific query conditions, and extracting each query keyword; determining each application field which corresponds to each query keyword, and querying corresponding sensor data in the grid database according to the application fields; and acquiring a query result which corresponds to each query keyword, sorting the query results by priority, and displaying and / or marking on a visual searching interface. In the query process according to the time interval, the geographical range and the query conditions, partitioning processing is realized. The aims of avoiding centralized processing of mass data, reducing processing burdens on the whole system and improving the searching performance of the whole system are fulfilled.

Description

technical field [0001] The present invention relates to the field of network information technology, and more specifically, relates to a method and system for searching entities of the Internet of Things. Background technique [0002] The Internet of Things is an important part of the new generation of information technology. The sensor network is an important part of the Internet of Things technology. The sensor network is a computer-accessible network composed of a large number of sensor devices distributed in space. Realistically monitor the physical or environmental conditions in different locations, that is, monitor data such as temperature, humidity, sound, light, vibration, pressure, movement, pollution, etc. through various sensors, to achieve such as environmental monitoring, intelligent traffic monitoring, industrial monitoring and perimeter anti-intrusion and other application functions. The sensor network is widely used in various fields to assist people to dire...

Problems solved by technology

[0006] In view of this, the present invention provides a method and system for searching entities of the Internet of Things to overcome the problem in the prior art that due to the fixed search matching conditions of sensors, and there is no interaction between sensors and no data interoperability is involved, when there are many sensors When querying with the entity it is attached to, it causes the query burden of the entire database
