The technical solution of the utility model is as follows:
A kind of low-speed wireless relay communications system, it is characterized in that: comprise information source computer, repeater, two 3G routers and stay of two nights computer, the information source computer is connected to a 3G router by repeater, another 3G router is connected to stay of two nights computer, communicates to connect by the 3G wireless communication link between two 3G routers.
Described repeater is to be formed by the wireless relay links that several XTEND radio station constitute, and wherein the number in XTEND radio station can increase according to the needs of repeater span or reduce.
Be connected by the RS232 serial ports between described information source computer and the repeater.
Be connected by the RS232 serial ports between described repeater and the 3G router.
Be connected by the RS232 serial ports between described 3G router and the stay of two nights computer.
Principle of the present utility model is: the information source computer is collected data to be sent, send data to the 3G router by serial ports, the normal communication link that constitutes by two 3G routers communicates, send data to stay of two nights computer by serial ports again, so far finish the transmission of data from the information source computer to stay of two nights computer, realized data are sent to no shielded area from the signal shielded area.
The beneficial effects of the utility model are as follows:
The utility model can effectively solve wireless signal shaded areas low speed data wireless transmission problem, adopts the mode of trunking traffic will be subjected to the signal of occlusion area to be forwarded to no occlusion area step by step by repeater; It is not high that the utility model can be applicable to various desired rates, but might exist in the wireless communication system of signal shielded area, functional.
Description of drawings
Fig. 1 is composition schematic block diagram of the present utility model
Wherein, Reference numeral is: 1, information source computer, 2, the XTEND radio station, 3,3G router one, 4,3G router two, 5, stay of two nights computer, 6, the RS232 serial ports; Solid line represents that wire communication connects, and dotted line represents that radio communication connects.
Embodiment
The utility model is based on XTEND technology and 3G technology, comprise an information source computer 1, repeater, two 3G routers and a stay of two nights computer 5, information source computer 1 is connected to a 3G router by repeater, another 3G router is connected between 5, two 3G routers of stay of two nights computer and communicates to connect by the 3G wireless communication link.
Described repeater is to be formed by the wireless relay links that several XTEND radio station 2 constitute, and wherein the number in XTEND radio station 2 can increase according to the needs of repeater span or reduce.
Be connected by RS232 serial ports 6 between described information source computer 1 and the repeater.
Be connected by RS232 serial ports 6 between described repeater and the 3G router.
Be connected by RS232 serial ports 6 between described 3G router and the stay of two nights computer 5.
As shown in Figure 1, adopt four XTEND radio station 2 to constitute repeater, the system principle of this structure is as follows: information source computer 1 is collected data to be sent, sends data to first XTEND radio station 2 by serial ports; First XTEND radio station 2 is transmitted to data second XTEND radio station 2 wirelessly; Second XTEND radio station 2 is transmitted to the 3rd XTEND radio station 2 with data ...., and the like data between the XTEND radio station, constantly transmit, receive data up to the 4th XTEND radio station 2, the 4th XTEND radio station 2 is transmitted to 3G router 1 by serial ports with data; 3G router 1 sends data to 3G router 24 by the 3G link; 3G router 24 sends data to stay of two nights computer 5 by serial ports.So far finish the transmission of data from information source computer 1 to stay of two nights computer 5.
This shows that in low-speed wireless relay communications system shown in Figure 1, first XTEND radio station 2 to the 4th XTEND radio station 2 constitutes repeated link as repeater, its effect is that data are sent to no shielded area from the signal shielded area; 3G router 1 and 3G router 24 constitute normal communication link, and its effect is to send the data to stay of two nights computer 5.
Why choosing the XTEND radio station and constitute wireless relay links, is because the XTEND radio station has characteristics such as MANET, low-power consumption, long transmission distance, and XTEND radio station support communication in moving, is fit to very much be applied in the transport monitor system.In addition, because it is low in energy consumption, can adopt powered battery, use very convenient.
