Concrete meaning in the present invention.
Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
The present invention proposes the self-organized network communication system of a kind of combination frequency division and time-division.It can make what is treasured using the system
Frequency resource is fully utilized, and will not be interfered between mainframe network, so as to improve the customer volume of system.With this
The system has also combined diversity technique simultaneously, adds the reliability of system.
As shown in figure 1, the system is mainly made up of the equipment of two grades of main frame and slave.One in one master-slave network
There are multiple slaves below main frame, main frame and slave up-downgoing use the form of alien frequencies, and are adopted between main frame and the slave of the network
It is transmitted with the form of time-division.That is the down going channel of main frame-slave uses a frequency to be communicated in the form of the time-division.From
The data feedback channel of machine-main frame then uses another frequency, is communicated in the form of the time-division.Being communicated between main frame, the frequency is few, and transmitting-receiving is adopted
With same frequency time-division communication.Distance closely uses low power communication pattern between main frame and slave, between main frame and main frame
Distance far uses powerful communication mode, and the frequency that the slave of heterogeneous networks uses is different, passes through frequency and communication model
Limitation is enclosed to ensure that situation about interfering will not be produced.Main frame is provided to send toward the slave belonging to oneself and referred to by agreement in work
Order, slave also can be toward main frame upload informations.It can communicated between each main frame in the case of having demand between other main frames.
To ensure the reliability to send instructions under main frame-slave, main frame applies two frequency bins to ensure from function simultaneously in communication process
Enough technologies accurately receive instruction.
Whole frequency range is divided into 4 points of f1, f2, f3, f4 by the system.As shown in Fig. 2 wherein f1, f4 bandwidth is identical, by f1 and
F4 bandwidth is divided into several small channels, and the frequency range is mainly responsible for main frame toward photos and sending messages under slave, each master-slave network in f1 and
A channel is respectively taken in f4, such as a master-slave network takes f11 as downstream frequency, while the network can be also taken in f4
The frequency that frequency range is in same position is f41 frequencies.F1, f4 point section are divided into N deciles so system can just accommodate N simultaneously
Individual master-slave network.Distinguish i.e. master-slave network 1 by the way of frequency division between each master-slave network is made using f11 and f41 master-slave networks 2
With f12 and f42 by that analogy.F11 and f41 two frequency bins send identical information simultaneously, are sent in the form of frequency diversity
Ensure that slave can accurately and reliably receive the instruction of main frame transmission to slave.With when each slave takes one among network
Gap, number of time slots determine the quantity of slave.F2 frequencies are mainly used in slave uplink band.So above and below each master-slave network
Line frequency is not both FDD communication pattern.
F3 frequency ranges are the communication between a main frame.Because the communication frequency between individual main frame is not very frequently so usual f3
The bandwidth of occupancy is narrow, is communicated between transmitting-receiving in the form of the time-division.
So main frame has three sendaisles, two receiving channels when receiver designs.Slave has a transmission channel two
Individual receiving channel, as shown in Figure 3.
Main frame analog portion is divided into three modules, and module 1 is responsible for sending f1 UHF band reception f2 frequency ranges, and module 2 is responsible for transmission
F4 frequency ranges, module 1 and module 2 are responsible for the communication between master-slave network.Because the scope between a master-slave network is smaller, institute
It is smaller with the transmit power of module 1 and module 2.The transmitting-receiving major function that module 3 is responsible for f3 frequencies is responsible between a main frame
Communication.Distance is slightly remote between general main frame, and the power of transmission is bigger.Baseband portion is responsible for modulation /demodulation, protocol processes, control
The work such as system.
Slave is responsible for f1, f4 reception and f2 transmitting using the design simplified, a module.
The system is applied to the flattenings such as fleet, fleet communication.Protected by using the technology of time-division, frequency division, frequency diversity
Card efficient stable reliably communicates.The quantity that both can guarantee that the user in the case of limited frequency resource using the technology improves
The utilization rate of frequency range, and can ensure the reliability of communication
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection with principle.
