Network server implementation method based on frequency multiplexing technique mainly include 1 serial server, it is N number of wirelessly turn serial ports dress
Set (N < 9), serial server with wirelessly turn serial port device and connected by serial ports, serial server is the nothing being each attached thereto
Line turns serial port device and distributes unique IP address, each wirelessly turns serial port device and works in different radio bands, channel it
Between bandwidth granularity 25kHz.
The serial server uplink communication is connect with fiber optic Ethernet interface, and downlink communication passes through serial ports and wireless turn of string
Mouth device connection, serial server can be attached thereto for each wirelessly turns the corresponding IP address of serial port device distribution and end
Slogan, address are corresponding with remote concentrator or table of merit rating.As shown in Figure 2.
Serial port device, uplink communication and the serial server of wirelessly turning passes through RS232 serial ports connection communication, downlink
Communication is wirelessly communicated with concentrator or table of merit rating by private network, and channel width 25KHz between serial port device is each wirelessly turned.Such as figure
Shown in 3.
As shown in Figure 1, a kind of network server implementation method system construction drawing based on frequency multiplexing technique provided by the invention,
Including optic_fiber intelligent skin 1, serial server 2 wirelessly turns serial port device 3, wirelessly turns serial port device 4 and wirelessly turns serial port device 5.
Wirelessly turn 3 working frequency range 230MHz of serial port device, wirelessly turn 4 working frequency range 229.975MHz of serial port device, wirelessly turns serial ports dress
Set 5 working frequency range 229.95MHz.Serial server with each wirelessly turn serial port device two-way communication connect by RS232 serial ports,
Serial server is by configured in advance to each distribution of serial ports end and remote concentrator or table of merit rating phase for wirelessly turning serial port device
Same IP address and port numbers.The data information of heterogeneous networks frequency range in the same area can be carried out unification by the network server
Acquisition uploads, and the mode of multiple public network GPRSs progress uplink communications is needed instead of traditional same region.
The course of work of the invention is as follows:
1, network server includes 1 serial server, and 3 wirelessly turn serial port device;
2,3 wirelessly turn serial port device and are attached respectively with serial server 2 by RS232, wirelessly turn serial port device 3
Working frequency range 230MHz wirelessly turns 4 working frequency range 229.975MHz of serial port device, wirelessly turns 5 working frequency range of serial port device
229.95MHz;
3, two-way interactive can be carried out with concentrator of the work under 230MHz frequency range or table of merit rating by wirelessly turning serial port device 3
Communication;
4, wirelessly turning serial port device 4 can be two-way with concentrator of the work under 229.975MHz frequency range or table of merit rating progress
It interactively communicates;

It interactively communicates;
6, as shown in figure 4, being allocated according to power grid background server address to network server portal address, it is desirable that
Power grid background server address and network server portal address are in same network segment.Grid service device address is set
192.168.1.1:6000;Network server portal address 192.168.1.100, gateway 192.168.1.1 are set.Network service
Device serial ports address is identical as the address of remote concentrator or table of merit rating;
7, first serial ports address of setting network server and wireless serial device 3 is 192.168.2.100.7000;
8, first serial ports address of setting network server and wireless serial device 4 is 192.168.2.101.7001;
9, first serial ports address of setting network server and wireless serial device 5 is 192.168.2.102.7002;
10, after the completion of configuring, when power grid background server needs to read the concentrator of address 192.168.2.100:7000
When data, power grid background server will read instruction by optical fiber and be issued to serial server, and serial server is according to prior point
The address choice correspondence prepared wirelessly turns serial port device, is wirelessly communicated with corresponding concentrator or table of merit rating,
It realizes and the data information of concentrator or table of merit rating is read.
11, network structure form, present networks carry out data acquisition, nothing to terminal concentrator or table of merit rating using the forms of broadcasting
Line private network has the unpacking ability of unpacking of data, and terminal concentrator or table of merit rating use multi-band communication mode when uploading data, prevent
Only packet loss phenomenon caused by data collision.
Ethernet communication part uses the ethernet frame format of standard, as shown in Figure 5.
Network server unpacks to the data that Ethernet is sent, one bag data of Ethernet, 960 byte, data portion
768 bytes wirelessly turn serial port module to each and distribute 96 bytes, and 8 modules amount to 8*96 byte=768 bytes, in this example
Wirelessly turn serial port module using 3 and occupies 3*96 byte=288 bytes.Wirelessly communicate 128 byte of a bag data length, private network without
Line communication frame format in the form of unicast as shown in fig. 6, be dealt into counterpart terminal for data wirelessly turning serial port module, due to adopting
With multi-band communication mode, acquisition data directly can be dealt into network server after receiving data by terminal, without data punching occurs
Emergence as.Data are packaged and are sent to background server by fiber optic Ethernet by network server, are completed primary complete
Network data exchange.
Such method replaces concentrator or table of merit rating to carry out distal end transmission to data by public network, reduces operation maintenance expense
With the safety of promotion network information interaction.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
