Abstract
The invention relates to a station platform/control box remote transmission device, which is characterized in that: a primary device is connected with a station platform host machine through a control cable and is connected with a digital-modulation transmission device through a 75-ohm bayonet connector (BNC)-typed E1 connecting wire; a secondary device is connected with a control box through a control cable and is connected with the digital-modulation transmission device through the 75-ohm BNC-typed E1 connecting wire; and the primary device and the secondary device are used for converting an analog voice signal and an RS485 data message to a standard 2.048Mbit/s pulse code modulation (PCM) signal, and simultaneously, are used for converting a received 2.048Mbit/s PCM signal to the analog voice signal and the RS485 data message. The station platform/control box remote transmission device has beneficial effect that: a communication engineering distance between the station platform host machine and the control box is enlarged by utilizing the digital-modulation transmission device, so the flexibility of a train dispatching system architecture can be improved.
Description
Technical field
The present invention relates to railway wireless train and transfer equipment, particularly a kind of station console/control capsule remote transmission equipment, equipment is used for the telecommunication between station console and the control capsule.
Background technology
At present; In China railways train dispatch radio communication equipment; Usually adopt the RS485 signalling methods between station radio set main frame and the control capsule; Its data message and analog voice signal directly transmit through control cable; Because the restriction of the direct transmission performance of controlled cable; Cause the engineering distance between station console main frame and the control capsule generally should not surpass 500 meters, therefore, make
Row are transferredThe alerting ability of system architecture is restricted.
2.048Mbit/s PCM digital link transmission technology is very ripe at present, in railway communication network and public communication network, all is widely used.Therefore; PCM (PulseCodeModulation pulse-code modulation) digital link transmission technology is applied between station radio set main frame and the control capsule and communicates, replace existing RS485 signalling methods and will make the engineering distance between station console main frame and the control capsule substantially exceed existing 500 meters.And the present domestic bibliographical information that this respect is not arranged as yet.
Summary of the invention
Deficiency in view of traditional signalling methods existence; The present invention provides a kind of remote transmission equipment and technology scheme; In this scheme; Transmission equipment utilizes number to transfer transmission equipment; Accomplish communicating by letter between station console main frame and the control capsule; Thereby realize that control capsule can zoom out the function of communicating by letter with the station console main frame, promoted the alerting ability of row adjusting system framework greatly.
The present invention is for realizing above-mentioned purpose; The technical scheme that is adopted is: station console/control capsule remote transmission equipment; Comprise main equipment and slave unit, it is characterized in that: main equipment is connected with the station console main frame through control cable, and transfers transmission equipment to be connected through 75 ohm of BNC type E1 connection leads and number; Slave unit is connected with control capsule through control cable, and transfers transmission equipment to be connected through 75 ohm of BNC type E1 connection leads and number;
Main equipment will come from the analog voice signal of station console main frame and the 2.048Mbit/s PCM signal that the RS485 data message changes into standard; Transfer transmission equipment to be transferred to slave unit through number; Simultaneously transfer transmission equipment to receive the 2.048Mbit/s PCM signal of the standard that comes from slave unit, and the 2.048Mbit/s PCM signal of the standard received is converted into analog voice signal and RS485 data message through number;
Slave unit will come from the analog voice signal of control capsule and 2.048Mbit/s PCM signal that the RS485 data message changes into standard transfers transmission equipment to be transferred to main equipment through number; Simultaneously transfer transmission equipment to receive the 2.048Mbit/s PCM signal of the standard that comes from main equipment, and the 2.048Mbit/s PCM signal of the standard received is converted into analog voice signal and RS485 data message through number;
The main equipment circuit mainly is made up of fpga chip, PLL chip, dsp chip, E1 monolithic transmitter and interface, and fpga chip is connected with PLL chip, dsp chip and interface respectively, and E1 monolithic transmitter is connected with PLL chip, dsp chip and E1 interface respectively; The slave unit circuit is identical with the main equipment circuit.
The invention has the beneficial effects as follows: utilize number transfer transmission equipment with station console main frame and control capsule communication engineering apart from expansion, improved the alerting ability of row adjusting system framework.
