The system is characterized in that the locomotive controller main CPU is respectively connected with the telephone transmitter and the audio power amplifier through a digital channel machine, the antenna is arranged on the digital channel machine, and the shunting interphone is provided with a shunting signaling key. The digital time-division wireless shunting system integrates shunting signaling and intercom together, and uses a command of preferentially inserting the shunting signaling, thus, the system preferentially selects the shunting signaling while maintaining the function of the original interphone, and the safety factor for shunting operators is improved.
Description
Technical field
The utility model belongs to railway transportation radio shunting system in the industrial working, particularly a kind of digital time-division radio shunting system.
Background technology
Railway signaling radio shunting system is the important component part of railway transportation organization of production in the industrial working; Used the radio shunting system equipment of artificial antenna car transferring system system the nineties, thoroughly changed and carried out the traditional approach of shunting service in the past, realized the shunting service wireless penetration with instruments such as lamp, flag or intercoms; Improved Shunting Service Efficiency; Reduce yard man's labour intensity, guaranteed shunting service safety, and obtained remarkable benefit.But the artificial antenna car transferring system is that frequency is occupied the rich and influential family, and it is many to establish platform; The zone is narrow and small, and the frequency layout is thrown in and received objective utilization condition restriction, and frequency is concentrated relatively; Very serious with interference frequently, Intermodulation Interference, monkey chatter etc.; But and the 400MHz frequency resource is in saturated and in short supply state, has not had new 400MHz intercommunication (networking) the frequency assignment at present, and the frequency interferences of 400MHz intercommunication (networking) simultaneously is still very serious; Can not satisfy the transportation production development because of frequency is nervous and protect the demand of producing with safety; So also incompatibility transportation technology requirement. set about grinding ten minutes necessity now with 400MHz digital time-division radio shunting system, the in short supply day by day and serious railway train arrangement operation of frequency interferences for frequency resource, 400MHz digital time-division radio shunting system grinds with significant meaning is arranged.
Summary of the invention
The purpose of the utility model provides the 400MHz digital time-division radio shunting system that a kind of frequency resource is abundant, do not have frequency interference together, Intermodulation Interference, monkey chatter, to overcome the deficiency of prior art.
To achieve these goals, the technical scheme that the utility model adopted is:
A kind of digital time-division radio shunting system; Comprise the wireless signaling coke oven controller and shunt intercom; Said wireless signaling coke oven controller comprises coke oven controller host CPU, clock circuit, antenna, transmitter, audio-frequency power amplifier and loud speaker; Said coke oven controller host CPU links to each other with clock circuit; Said coke oven controller host CPU joins with transmitter and audio-frequency power amplifier respectively, and said audio-frequency power amplifier is connected with loud speaker, and said coke oven controller host CPU shows device through a lamp circuit and lamp and is connected.Be characterized in: said coke oven controller host CPU joins with transmitter and audio-frequency power amplifier respectively through a digital channel device, and antenna is arranged on the digital channel machine, and the said intercom of shunting is provided with the signaling of shunting (order of light shows signal) button.
Said coke oven controller host CPU also is connected with a signaling record cell.
Comprise digital signal processor (DSP), AD conversion unit and D/A conversion unit in the said digital channel machine.
The utility model integrates shunt signaling and intercommunication, and adopts the instruction of the preferential intrusion of signaling of shunting, and makes the utility model under the function that keeps original intercom, preferentially selects the signaling of shunting for use, has improved shunting service personnel's coefficient of safety.
Description of drawings
Fig. 1 is the wireless signaling coke oven controller theory diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe in detail.
The utility model comprises the wireless signaling coke oven controller and shunts intercom; Said wireless signaling coke oven controller comprises coke oven controller host CPU, clock circuit, digital channel machine, antenna, transmitter, audio-frequency power amplifier and loud speaker; Said coke oven controller host CPU links to each other with clock circuit; Said coke oven controller host CPU digital channel machine joins with transmitter and audio-frequency power amplifier respectively; Said audio-frequency power amplifier is connected with loud speaker, and said coke oven controller host CPU shows device through a lamp circuit and lamp and is connected; The said intercom of shunting is provided with the signaling button of shunting, and said coke oven controller host CPU also is connected with a signaling record cell; Comprise digital signal processor (DSP), AD conversion unit and D/A conversion unit in the said digital channel machine.
The analog to digital converter digitlization that the intercom signal of shunting that the radio frequency receiving terminal of the wireless signaling coke oven controller of the utility model is received through antenna is given digital signal processor DSP; The software of DSP is handled signal; Through demodulation, deciphering and decoding, digital to analog converter (DAC) is with its speech simulationization.Wherein audio digital signals is reduced into audio signal rear drive audio power amplifying circuit through decryption processing, in loud speaker, hears the speech of transmit leg; And the intercom numeral of shunting that receives is shunt signaling through after the high-frequency circuit demodulation close processing, then removes controller ride signaling controller and drive point circuit for lamp through serial ports.The utility model carries out voice digitization with the voice signal of transmitter through analog to digital converter (ADC); Through the built-in DSP of digital channel machine (digital signal processor) software voice signal being carried out digital coding handles; And the digital coding of bandwidth reduction modulated (4FSK), and digital to analog converter (DAC) is transmitted to shunt intercom to radiofrequency launcher through antenna with modulated signal imitationization and with it.
The wireless signaling coke oven controller of the utility model is behind the signaling-information of receiving the intercom of shunting; No matter whether the wireless signaling coke oven controller is in the intercommunication state; All can insert signaling-information and processing by force; To guarantee the timely processing of signaling-information, improved shunting service personnel's coefficient of safety.
The signaling record cell of the utility model is used to store the various preset data that concern of shunting between signaling button and the drive point circuit for lamp, and the signaling button operation of shunting on the intercom of being convenient to shunt is simple.
The content of not doing in this specification to describe in detail belongs to this area professional and technical personnel's known prior art.
