Abstract
The utility model relates to a handheld table for receiving a shunting operation list. The circuit of the handheld table comprises an RF unit, an operation display unit formed by an LCD and a keyboard, a baseband processing unit and an audio-frequency part; the baseband processing unit comprises a DSP(digital signal processor), an MCU (microcontrol unit), and an internal memory connected with each other; and the baseband processing unit is connected with the RF unit, the LCD, the keyboard, the audio-frequency part, an external interface part, and a PTT (Push To Talk) function key. The handheld table can be matched with a district chief table to use, can transmit the shunting operation list through a wireless communication channel, and can display and operate the shunting operation list. The handheld table has the benefits that the defects of printed paper shunting operation list are overcome, the time for shunting operation is shortened, the work efficiency is improved, the probability of human error is lowered, and a shunting person can conveniently and efficiently perform shunting operation.
Description
Technical field
The utility model relates to the wireless data transmission and the operation display device of railway plane car transferring system, particularly a kind of hand-held station that is used for the shunting operation sheet reception.
Background technology
In railway plane is shunt, shunting operation sheet is being undertaken very important role, and the person on duty is printed shunting operation sheet, gives the shunter, the hand-held papery shunting operation sheet of shunter carries out shunting service, and need converse and send instruction by hand-held intercom and driver when shunting service.Printing papery shunting operation sheet, shunting operation sheet, to be delivered to shunter's operating process more loaded down with trivial details, regular hour need be expended, efficient is low, the papery shunting operation sheet goes out the situation of active and damage in use easily, certain inconvenience is arranged during operation, therefore, the railway plane car transferring system has the huge space that needs improvement and innovation in this respect.
Summary of the invention
Existing situation in view of this field, it is that the head of district's platform and the hand-held station of shunting are realized railway plane shunting operation sheet technical scheme of transmission that the purpose of this utility model just provides a kind of Heibei provincial opera communication equipment that utilizes, promptly shunting operation sheet is converted to data format with computer, data sent to head of district's platform then, utilize wireless channel transmission shunting operation sheet by head of district's platform, the shunter receives, shows and the operation shunting operation sheet by hand-held station, can greatly facilitate the time and the efficient of shunting service like this.
The technical solution of the utility model realizes: a kind ofly be used for the hand-held station that shunting operation sheet receives, it is characterized in that, operation display unit, baseband processing unit and audio-frequency unit that its circuit comprises the RF unit, is made up of LCD and keyboard; Baseband processing unit is is mainly connected and composed by digital signal processor DSP, microcontroller MCU and internal memory, and baseband processing unit connects RF unit, LCD, keyboard, audio-frequency unit, external interface part and PTT function key respectively.
Hand-held station described in the utility model cooperates head of district's platform to use, utilize wireless channel transmission shunting operation sheet, and on hand-held station, can show and operate shunting operation sheet, its beneficial effect is: the defective that has overcome the single operation of seal papery shunting service, shortened the time of shunting service, improved operating efficiency, reduced the probability of human error, can make shunter's convenience and carry out the shunting service operation efficiently.

Embodiment
In order more to be expressly understood the utility model, describe embodiment in conjunction with the accompanying drawings in detail:
The hardware system of realizing the shunting service single transport by the Heibei provincial opera communication equipment comprises: be used for the computer of precompile shunting operation sheet, head of district's platform, hand-held station.
Be illustrated in figure 1 as shunter's hand-held station design, operation display unit, baseband processing unit and audio-frequency unit that circuit comprises the RF unit, is made up of LCD and keyboard; Baseband processing unit is is mainly connected and composed by digital signal processor DSP, microcontroller MCU and internal memory, and the port of baseband processing unit connects RF unit, LCD, keyboard, audio-frequency unit, external interface part and PTT function key respectively.
Be illustrated in figure 2 as head of district's platform design, head of district's platform comprises power supply, external communication interface, MCU master control, radio receiving-transmitting unit part, phonological component etc.Wherein, power supply adopts the power module form, AC220 input, output+7.2V ,+3.3V.+ 7.2V uses for radio receiving-transmitting unit, and+3.3V is for MCU and external communication interface, and other peripheral hardwares are used.MCU communicates by RS232 interface and outside and channel device.Wireless channel can carry out data, speech transmissions.
Shunting operation sheet is deposited with the EXCEL document format in computer, and content comprises as follows: time, the group of shunting, running number, number number, work out the people, collude preface, not, information such as station track, mode, a number, note.
According to the form below carries out data format and compiles, and wherein information bit is the shunting operation sheet content:
| Frame head | Frame length | Source address | Destination address | Information bit | Check code | Postamble |
| 10?02? | ?XX? | XX? | XX? | XX? | XXXX? | 10?03? |
| 2 bytes | 2 bytes | 1 byte | 1 byte | The N byte | 2 bytes | 2 bytes |
The information bit reference format is according to the following table editor:
After finishing, compiling sends to head of district's platform.
Head of district's platform is judged the data that computer transmits, if be the shunting service forms data, these data are carried out according to the arrangement of packing of the data format of on-air radio transmission, the data format of on-air radio transmission is according to as undertissue: (bit synchronization) (72bit)+(frame synchronization) (48bit)+data (n bit)+CRC (16it) .CRC check code generator polynomial is: G (X)=X16+X12+X5+1, the verification content is the data bit full content.The full name of CRC is Cyclic Redundancy Check, and Chinese is a cyclic redundancy check (CRC).
After the hand-held station of shunting receives these data, be reduced to shunting operation sheet, and shunting operation sheet is stored in the memory, prepare against and manipulate, and the prompting shunting operation sheet is received on display screen according to the information bit standard data.
The shunter accesses shunting operation sheet by keyboard, operate according to shunting operation sheet after checking, as operations such as modification, affirmation, deletions, after finishing, operation withdraws from the shunting operation sheet interface, send prompting simultaneously, whether shunting operation sheet is preserved, if determine, amended shunting operation sheet is saved in the memory again, and the words of cancellation are not preserved the shunting operation sheet of modification.Return the wait of main interface and receive new shunting operation sheet or new keyboard response.
According to the above description, can realize scheme of the present utility model in conjunction with art technology.
