Wireless sensor network gateway employing dual communication modes and control method

Abstract

The invention discloses a wireless sensor network gateway employing dual communication modes and a control method. The gateway comprises a processor module, a general packet radio service (GPRS) module, a serial port communication module, a storage module, a wireless communication module and a power and charging module, wherein the processor module is connected with the serial port communication module, the storage module and the wireless communication module respectively; the GPRS module is connected with the serial port communication module; and the power and charging module is connected with a power supply battery. The processor module receives data from a wireless sensor network through the wireless communication module, analyzes the data, and extracts information. The serial port communication module is connected with a processor and the GPRS module. The processor controls the transmission of the working state and the information of the GPRS module through the serial port communication module. In case of a poor network signal or a network failure, the information is stored on a local secure digital (SD) card. The charging efficiency of the battery is effectively improved, and the life cycle of a node is prolonged.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a dual communication mode wireless sensor network gateway and a control method. Background technique [0002] In recent years, wireless sensor networks have developed rapidly, and have been widely used in real-time monitoring of farmland data and industrial production environments, and even military intelligence collection. Traditional real-time data collection mainly relies on handheld instruments for on-site and one-by-one measurement. Applying wireless sensor networks to real-time monitoring of farmland, industrial production environments, and battlefields can effectively solve the shortcomings of traditional monitoring methods, improve the level of informatization, and make fast reaction. [0003] The gateway is responsible for collecting the data of all nodes and sending it to the server. Currently, there are wired or wireless methods. The wired way is const...
