Abstract
The utility model discloses a railway terrestrial wireless radio station. This radio station includes microprocessor MCU, coder codec, receiver, transmitter, LCD display screen, digitron display screen, warning button, storage flash, net gape and speaker, wherein, MCU and codec are connected, and codec is connected with receiver, transmitter, speaker through operational amplifier respectively, and MCU is connected with LCD display screen, digitron display screen, warning button, storage flash, net gape respectively. The utility model discloses compare with internal train running state, the replenishment under existing train early warning and alarm management system can be regarded as in the terrestrial wireless radio station, can improve train driving safety greatly, satisfies railway user's demand. Use this ground station can realize that the train when being close to a certain area, carrying out the train and is close to the early warning to when some situation appearing on ground, send the warning to being close the train that traveles.
Description
Technical field
The utility model relates to radio station, particularly a kind of railway ground wireless station.
Background technology
Along with the development of domestic bullet train, the extensive installation of train protection warning mobile unit, railway ground early-warning and warning system also progressively will carry out use.If bullet train close to some level crossing, construction ground or other special areas time, ground staff does not receive relevant Train Approaching early warning information, probably causes irremediable loss; Equally, if when ground region occurs that near accident impact, train normally travels, also need, to neighbouring train and alarm, trainman to be done some preparations, avoid occurring secondary accident.
Summary of the invention
The purpose of this utility model is to realize when some special area of Train Approaching, ground can receive train close to early warning, the train travelled near timely alert notice when ground region goes wrong and research and develop a kind ofly support that railway is close to the railway ground wireless station of early warning and warning function.
The technical scheme that the utility model is taked is: a kind of railway ground wireless station, is characterized in that: this radio station comprises Micro-processor MCV, coder Codec, receiver, transmitter, LCD display, digitron display screen, alarm key, storage Flash, network interface and loud speaker; Wherein, MCU and Codec connects, and Codec is connected with receiver, transmitter, loud speaker respectively by operational amplifier, and MCU is connected with LCD display, digitron display screen, alarm key, storage Flash, network interface respectively.
The beneficial effects of the utility model: compared with current domestic train operation state, land station of the present utility model as supplementing under existing train early warning and alarming and managing system, can improve train traffic safety, meet the demand of railway user greatly.Use this land station, train can be realized when close to a certain area, carry out Train Approaching early warning, and when there is some situation on ground, report to the police to sending close to the train travelled.
Accompanying drawing explanation
Fig. 1 is that railway is close to early warning and warning system block diagram;
Fig. 2 is ground wireless station composition frame chart in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
With reference to Fig. 1, railway is made up of data acquisition encoder, 800MHz locomotive station (LBJ), intersection alarm equipment, construction protection warning device, Train Approaching precaution device, passenger train afterbody safety device (KLW) and special maintenance equipment close to early warning and warning system.Wherein, for the railway supported of construction protection warning device and intersection alarm equipment close to the ground wireless station of early warning and warning function, according to the difference of application scenarios, different equipment names can be carried out.
Encoder and LBJ are installed on locomotive, KLW is installed on last vehicle of train, and intersection alarm equipment is installed on road junction, work business staffing construction protection warning device and precaution device, attendant is equipped with portable testboard and data management system, goes out to put in storage checkout equipment and is installed on departure from and returning to engine shed detection site.
Railway is close to early warning and warning system major function:
1, classification stores: the various information sending and receive; Every category information storage capacity is no less than 1000; Circulation covers; Data extraction is carried out by USB interface.
2, can arrange and organize kilometer post (unit of Along Railway home position) and Train Approaching early warning distance more.
3, Train Approaching early warning information can be received, and show distance and the time of advent at train and road junction by large display screen, and according to sending different prompt tone the time of advent.
4, local clock and manual mode adjustment function is possessed.
5, automatic correcting time: the clock correction information received and Local clock differ by more than 1 minute.
6. there is self-checking function.
7. start and remove and report to the police: " warning " button pressing radio station, radio station every 5-10 random continuous second sends six frame accident alarming information and to go forward side by side line item.Again press " warning " button, remove and report to the police, radio station sends six frames continuously and removes information.
8, power supply: AC220V+ battery-backed power source.Adopt AC-powered in floating charge mode for reserve battery charges; When alternating current interrupts, automatically switch to reserve battery and power; After alternating current recovers, then automatically switch to AC-powered.
With reference to Fig. 2, railway ground wireless station comprises Micro-processor MCV, coder Codec, receiver, transmitter, LCD display, digitron display screen, alarm key, storage Flash, network interface and loud speaker; Wherein, MCU and Codec connects, and Codec is connected with receiver, transmitter, loud speaker respectively by operational amplifier, and MCU is connected with LCD display, digitron display screen, alarm key, storage Flash, network interface respectively.
Ground wireless station by receiver receive train send close to early warning information, being carried out signal amplitude adjustment by operational amplifier and Codec chip and be sent to MCU(model is LPC4337), MCU decodes to the received signal, and by Train Approaching information displaying in LCD display and digitron display screen, undertaken close to early warning playback by loud speaker simultaneously.
User is by alarm key trigger alarm function, and MCU carries out alarm code, and carries out signal amplitude modulation by Codec chip, is sent to transmitter, the train run near being sent to by proprietary frequency range.
All warning messages close to early warning information and transmission received, all store by MCU, carry out statistical conversion by USB flash disk in storage Flash, are convenient to the later stage to carry out data analysis and problem investigation.
Realize the utility model, special frequency must be used to close to early warning and warning, specify coded system, determine the agreement close to early warning and warning.Ground wireless station frequency configuration of the present utility model and coded system see the following form:
| Sequence number | Channel frequency (MHz) | Coded system | Channel service |
| 1 | 821.2375 | POCSAG | Train Approaching early warning |
| 2 | 866.2375 | FFSK | Report to the police |
