Embodiment Construction

[0022] Specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions and drawings, but the embodiments of the present invention are not limited thereto.

[0023] figure 1 Shown is a schematic diagram of the application system network of the present invention. It is mainly composed of WSN monitoring nodes, wireless data transmission equipment and monitoring center based on WSN, GPRS and GPS. The WSN monitoring node transmits the collected data to the wireless data transmission device in a multi-hop manner through the WSN network. The wireless data transmission device is mainly responsible for connecting the WSN network and the Internet network, so that the information is effective and error-free between two different networks. transmission. The wireless data transmission equipment sends the received data to the remote monitoring center with independent IP address and port number through the GPRS network, and the mo...

Abstract

The invention discloses a wireless data transmission device based on a WSN (wireless sensor network), a GPRS (general packet radio service) and a GPS (global position system). The wireless data transmission device mainly comprises a GPRS RF (radio frequency) module, a ZigBee RF module, a GPS module, a 32-bit ARM (automatic route management) processor and a power management module, wherein the ARM processor is a connecting link among the modules; and the ARM processor is connected with the GPRS RF module by a UART1 (universal asynchronous receiver / transmitter), connected with the ZigBee RF module by an SPI (serial peripheral interface), and connected with the GPS module by a UART0. In addition, for improving the reliability of the device and ensuring the reliable forwarding of massive data, the device also can comprise an NAND FLASH memory which is directly connected with the ARM processor by parallel I / O interfaces. By using the device disclosed by the invention, the transmission of remote WSN monitoring data is facilitated, the reliability of WSN data transmission is improved, the design cost is saved, the anti-interference performance of the system is improved, and the time synchronization of data information is guaranteed by using the GPS module.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a wireless data transmission device based on the integration of WSN, GPRS and GPS networks, which is mainly used for the transmission of remote WSN monitoring data. Background technique [0002] With the development of communication technology, wireless communication has made up for the shortage of wired communication with its advantages of cheapness, convenience, wide coverage and strong scalability. Traditional data transmission is mostly realized by laying cables, optical fibers and other wired methods, which have the advantages of stable and reliable transmission and high data transmission rate. However, in areas with harsh environments, remote locations, and a large number of monitoring points, it is obviously inappropriate to use wired transmission. Mobile communication technology is one of the fastest growing, most widely used and most cutting-edge communication field...
