Abstract
The invention discloses a serial-port communication optical transceiver and wireless spread spectrum joint communication system. The system is mainly provided with a substation communication machine, serial-port cables, two serial-port optical machines, a spread spectrum radio, a dispatching spread spectrum radio and a dispatching end data channel cabinet, wherein one end of one serial-port cable is connected with the output end of the substation communication machine and the other end of the serial-port cable is connected with the input end of one serial-port optical machine; the output end of the serial-port optical machine is connected with the input end of the spread spectrum radio via another serial-port cable; the spread spectrum radio is connected with the dispatching spread spectrum radio through wireless transmission; and the output end of the dispatching spread spectrum radio is connected with the input end of the dispatching end data channel cabinet via a serial-port cable. The system has the following positive effects: 110kV data can be normally transmitted to a master dispatching station; the bit error rate of the channel is low; and the telecontrol data in the station are accurately transmitted. The system has the advantages of low investment and low bit error rate, and is simple in installation and debugging.
Description
Technical field
The present invention relates to the system of a kind of optical communication and radio spread spectrum communication, relate in particular to the way integrated communication system of serial communication optical transceiver and wireless frequency expansion.
Background technology
Optical communication has the frequency band of allowing very wide, and transmission capacity is very big; Loss is very little, and repeater span is very long and the error rate is very little; In light weight, volume is little; Anti-electromagnetic interference performance is good; Leak for a short time, security performance is good; Save metal material, help lot of advantages such as resource use rationally.
Spread spectrum communication starts from military communication the earliest, and up to the end of the eighties, U.S. FCC has cooked up ISM band, and can be used by the business telecommunication that adopts spread spectrum communication mechanism.Because spread spectrum communication is anti-interference improving signal receiving quality, confidentiality, increasing the power system capacity aspect all has outstanding advantage.Spread spectrum communication is promptly civilian, and the business telecommunication field is popularized and opened.
Along with progressively going deep into of the upgrading of rural power grids, the quantity of the newly-built transformer station of electrical network also increases thereupon, but because other factors causes the communication mode of newly-built transformer station and county's regulating mechanism to relatively lag behind, causes the remote action data of newly-built transformer station can not in time upload county's accent.
Summary of the invention
In view of this, the way integrated communication system that the purpose of this invention is to provide a kind of serial communication optical transceiver and wireless frequency expansion.
The technical solution used in the present invention is:
The way integrated communication system of a kind of serial communication optical transceiver and wireless frequency expansion, mainly be provided with transformer station's communication machine, serial interface cable, the serial ports ray machine, spread spectrum receivers, the scheduling spread spectrum receivers, dispatching terminal data channel cabinet, wherein, serial interface cable one end connects the output of transformer station's communication machine, and the other end connects the input of serial ports ray machine, and the output of serial ports ray machine is connected with the input of spread spectrum receivers by serial interface cable, spread spectrum receivers is connected by wireless transmission with the scheduling spread spectrum receivers, and the output of scheduling spread spectrum receivers is connected by the input of serial interface cable with dispatching terminal data channel cabinet.
The serial ports ray machine is two.
Good effect of the present invention is:
The present invention can be with 110KV data normal transmission to scheduling station, and the passage error rate is low, and the remote action data transmission is correct in standing.
Small investment of the present invention, Installation and Debugging are simple, the error rate is low.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As seen from Figure 1, the way integrated communication system of a kind of serial communication optical transceiver and wireless frequency expansion, mainly be provided with transformer station's communication machine, serial interface cable, the serial ports ray machine, spread spectrum receivers, the scheduling spread spectrum receivers, dispatching terminal data channel cabinet, serial interface cable one end connects the output of transformer station's communication machine, and the other end connects the input of serial ports ray machine, and the output of serial ports ray machine is connected with the input of spread spectrum receivers by serial interface cable, spread spectrum receivers is connected by wireless transmission with the scheduling spread spectrum receivers, and the output of scheduling spread spectrum receivers is connected by the input of serial interface cable with dispatching terminal data channel cabinet.
35KV too hole transmission line is the peaceful conveyance system that becomes of 110KV, along 35KV 8.19 kilometers of newly-built optical fiber of hole line too, only has fibre circuit not have transmission equipments such as ray machine.
