Description
Technical field
The utility model relates to a kind of Morse code transmission equipment, specifically, relates to the data acquisition and the encoding and decoding of optical communication Access Network.
Background technology
When the distance of being separated by when transmitter and sender is far, because Morse code is an analog signal, can't long-distance transmissions, and to deliver to sender to the information of transmitter by artificial repeatedly switching, be very easy to like this make mistakes.
ITU G.703 file (No. 703 file of the committee of International Telecommunications Union) describes the time-division multiplexing (TDM) implementation method, time is divided into isometric timeslice, usually represent with a frame, one frame is 125us, per 16 frames are a multi-frame, and each frame is divided into 32 time slots, is followed successively by TS0, TS1, TS2 ... TS31.Wherein TS0 is a synchronization slot, and TS16 is the signalling time slot, and other 30 is data slot..
Close technology:
Adopt time-division multiplexing (TDM) can realize remote speech channel transmission, synchronous 64K path, asynchronous transparent path, E/M signaling, 2/4 line path, magnetite interface.
Above technology all is that digital coding is inserted in the time slot, and by transmission, decoding is reduced into original data again.
Retrieval situation:＜application number〉00816748,＜denomination of invention〉be used for the messaging delivery services of Digital Subscriber Loop.
The technical characterictic of close technology and retrieval situation: be used for providing messaging delivery services such as voice service by Digital Subscriber Loop, the voice data coding is inserted in the time slot, by transmission, decoding is reduced into voice data again.
Deficiency is: the Morse code transmission is not provided in the business that provides.
Summary of the invention
The purpose of this utility model provides a kind of intelligent Morse code local loop transmission equipment, specifically, be to solve Morse code needs human relay working in long-distance transmissions problem, promptly use this equipment, need not manual intervention, just can realize the remote accurately transmission of Morse code.
The purpose of this utility model is to realize like this.
The long-distance transmissions of Morse code needs two intelligent subscriber loop components, and an equipment is installed in this locality, is called local device; Another equipment is installed in far-end, is called remote equipment.Local device is connected with transmitter, and remote equipment is connected with sender.
Local device and remote equipment all comprise interface disc and control panel, and local device is finished data acquisition, and remote equipment is finished reduction of data, need not manual intervention.
The utility model adopts data interface techniques, Computer Analysis treatment technology, digital encoding and decoding technique, finish collection, analog-to-digital conversion in the transmitter direction to the telegraph code signal, become E1 (No. 1 standard of the european telecommunication) signal of standard, E1 transmission channel [can be equipment such as PDH (PDH (Pseudo-synchronous Digital Hierarchy)) equipment, SDH (synchronous digital hierarchy) equipment, spread spectrum device, satellite communication] by standard is delivered to far-end, again by decoding, be reduced into analog control signal, give sender, realize the transmission of telegraphic signal.
At local terminal, interface disc adopts high withstand voltage photoelectrical coupler, Morse telegraphy is carried out the isolation of voltage earlier, avoid the computer digit signal of the forceful electric power signal infringement interference digital collection plate of control desk, with microprocessor the output signal of photoelectrical coupler is disappeared and to tremble collection with data, encode again, become the computer digit signal, in signalling time slot, this time slot can transmit 30 tunnel Morse telegraphy 1 64K of this signal insertion standard E1 signal.
At far-end, interface disc according to different ways, carries out digital to analog conversion to the signal that receives from the E1 mouth, and the analog signal of reduction is delivered to corresponding sender port respectively, finishes the transmission of Morse code in the intelligent subscriber loop component.Because the asymmetry of transmitter end and sender end for the ease of using, has adopted the switch setting on interface board, make every block of plate promptly can be placed on the transmitter end, also can be placed on the sender end and use.
The digital signal of changing in the interface is inserted in the 2M code stream (TS16 time slot) of ST-BUS bus by the microprocessor of control panel, passes to the opposite end by transmission equipment.
Directly be connected by backboard between Morse code interface disc and the control panel.
The utlity model has following advantage and good effect;
The telegram of transmitter and sender transmission in the past is by human relay working, be time-consumingly to make mistakes easily again, adopt the transmission technology of Morse code at the intelligent subscriber loop component, original analog signal is become digital signal, utilize digital E1 transmission, promptly need not human relay working, be not subjected to distance limit again, the telegram transmission reliability is greatly improved.
