Sensing system for large-scale wireless sensor and M2M communication method thereof

Abstract

The invention discloses a sensing system for a large-scale wireless sensor and an M2M communication method thereof. A part of the sensor modules are connected within the coverage of the central sensor. The direct connected sensor modules work in the Normal mode, which lays a precondition for the subsequent M2M communication mode, then the classification of direct communication and M2M communication is completed through the communication of the server, the network transmission module and the central processing unit with each sensor module, and finally each module performs data collection and upload according to the determined working mode. The system and method thereof combine the M2M communication mode with the direct connection communication mode, which greatly reduces the direct connection load of the central processing unit, saves the data ports, and greatly increases the number of sensor modules that may be connected originally.

Description

technical field [0001] The invention belongs to the field of wireless communication and electronic technology, and in particular relates to a large-scale wireless sensor sensing system and an M2M communication method thereof. Background technique [0002] The wireless sensor perception system is a wireless ad hoc system including temperature and humidity sensors, light sensors, air pressure sensors, color sensors, and distance sensors, a variety of wireless sensor modules, a central processing unit, and a network transmission module. The monitoring and network transmission upload the data to the server in time, and then the server makes the required judgment instructions according to the uploaded data, realizing the fully closed perception system of real-time information exchange, intelligent monitoring and adjustment. With the introduction of concepts such as "Internet +" and smart agriculture, sensor perception systems have been widely used in various fields, such as agric...
