Embodiment Construction

[0019] The technical scheme and working principle of the present invention will be further explained below in conjunction with the accompanying drawings.

[0020] See figure 1 , a monitoring system of a ZigBee network combined with GPRS designed by the present invention includes a ZigBee network data acquisition layer, a GPRS network data transmission layer, and a PC monitoring center. The connection between the ZigBee node and the GPRS network is mainly through the serial port communication between the ZigBee sink node and the GPRS communication module. The GPRS module communicates with the PC through the GPRS data transmission protocol. ZigBee nodes mainly adopt the ZigBee protocol based on IEEE802.15.4 for wireless communication.

[0021] The composition of the ZigBee network data acquisition layer above includes a ZigBee coordinator, that is, a sink node, a router, and a terminal device, that is, a sensor node. The ZigBee protocol stack mainly includes driver layer, pro...

Abstract

The invention belongs to the field of wireless sensor network communication, in particular to a ZigBee network wireless monitoring system combined with the general packet radio service (GPRS). In order to overcome the defects existing in wired monitoring system data transmission and to satisfy urgent demands for wireless monitoring systems by certain special environment, a wireless monitoring system combined with GPRS networks and ZigBeenetworks is provided. The ZigBee network monitoring system combined with the GPRS specifically comprises a ZigBee network data collecting layer, a GPRS network data transmission layer and a monitor center, wherein a personal computer (PC) serves as a management layer in the monitor center. The ZigBee network monitoring system combined with the GPRS is capable of guaranteeing reliable and real-time transmission of data and reducing investing and maintaining cost, good in communication quality, low in power dissipation and capable of reducing shortcomings existing in long distance communication.

Description

technical field [0001] The invention belongs to the field of wireless sensor network communication, in particular to a ZigBee network wireless monitoring system combined with GPRS. Background technique [0002] Monitoring system is of great significance in the field of industrial control. In many public places in the control field, especially in some unattended and scattered sites, it is necessary to collect a lot of important data in real time, so as to understand and analyze the status of the site in time, and send necessary control commands according to the real-time situation. However, traditional monitoring systems generally need to build and maintain wired or wireless communication networks by themselves. The investment and maintenance costs are relatively high, and the wired data transmission method largely limits the expansion of application occasions, such as remote monitoring Monitoring production processes such as electricity, railways, mining and large steel mil...
