Abstract
The utility model relates to an alarm for an unattended railway crossing, which is a device for forecasting the transit of a train to the unattended railway crossing. The utility model is composed of a signal collecting emitter and a signal receiving alarm, wherein the signal collecting emitter is installed at the position which is 1.5 km away from the unattended railway crossing along the up-run or the down-run, the signal of the train transit is collected by a signal collecting device, and the signal which is A/D converted by an A/D converter and processed by a microprocessor is encoded and wirelessly emitted by an encode emitter. The signal receiving alarm is installed at the point of the unattended railway crossing. After the signal of the train transit, which is emitted wirelessly by the signal collecting emitter, is received by a signal receiver, the signal is decoded by a decoder and processed by the microprocessor, and then a sound and light alarm signal is sent out by the alarm.
Description
The utility model relates to a kind of device that is exclusively used in to the unmanned road junction forecast of railway train passage.
Railway has many big and small highways, intersection along the line, promptly so-called level crossing.The grade separation road junction that the magnitude of traffic flow is bigger in the city, in the rural area, particularly remote districts the level crossing mostly be the level crossing road junction, wherein a large amount of is the unmanned road junction that nobody guards.Owing to lack the warning means that actv. can forecast train passage, add all multifactor influences such as railway line situation, buried natural environment and climate condition, various pernicious traffic accidents happen occasionally in the level crossing, cause tremendous loss, the safe operation that also jeopardizes train simultaneously not only for passing people's lives and properties.For this reason, though some manufacturer has developed some auxiliary warning devices that are used for the level crossing, owing to be subjected to the restriction of railway administration particularity and application conditions, these additional alarm devices are difficult to be applied to unmanned road junction.At first, aspect means of communication, these warning devices adopt wire communication more, and not only cost is higher, administer and maintain also relatively difficulty.Secondly, the restriction of remote districts, place, unmanned road junction power supply also makes general warning device move.
The purpose of this utility model promptly is to design a kind of warning device that is exclusively used in to the unmanned road junction forecast of railway train passage.
To achieve these goals, the utility model utilization acquisition of signal projector of working in coordination and signal receive annunciator and form the unmanned crossing alarm device of a kind of railway.The acquisition of signal projector is installed on unmanned road junction upstream or downstream 1.5Km with at a distance, and the train passage signal of being gathered is the coding wireless transmission after A/D conversion and microprocessor analysis processing; Signal receives annunciator and then is installed in place, unmanned road junction, and it sends the sound and light alarm signal after receiving train passage signal by acquisition of signal projector wireless transmission after decoding and microprocessor analysis processing.Acquisition of signal projector and signal receive the required DC regulated power supply of annunciator and are provided by solar battery power.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the unmanned crossing alarm device of the utility model railway.
Accompanying drawing 1 is the acquisition of signal projector of the unmanned crossing alarm device of the utility model railway and the block diagram that signal receives annunciator;
Accompanying drawing 2 is the circuit diagram of wireless forward signal collector;
Accompanying drawing 3 is the circuit diagram of audio signal sample device;
Accompanying drawing 5 receives signal receiver, demoder, microprocessor and alarm circuit figure in the annunciator for signal;
Accompanying drawing 6 is the solar battery power circuit diagram.
With reference to the accompanying drawings 1, the acquisition of signal projector in the utility model mainly comprises signal picker, A/D converter, microprocessor, coded transmitter and power supply and is installed on unmanned road junction upstream or downstream 1.5Km with at a distance.The train passage signal of signal picker collection carries out A/D conversion and after microprocessor carries out analysis and judgement, by coded transmitter coding wireless transmission through A/D converter.Power supply is by solar cell and storage battery and mu balanced circuit is formed and provide DC regulated power supply for signal picker, A/D converter, microprocessor and coded transmitter.
The effect of signal picker is to gather the train passage signal, and it can take three kinds of different patterns, i.e. associated mode signal picker, wireless forward signal collector and audio signal sample device.
The associated mode signal picker is the simplest, and the sensor that it adopts is a permanent magnetism sensor and a side that is installed on rail, and the train passage signal of being gathered is directly sent into microprocessor by lead after the A/D conversion.
With reference to the accompanying drawings 2, wireless forward signal collector is made up of sensor, projector and receptor.Sensor can be permanent magnetism sensor or vibration sensor and a side that is installed on rail.The electric signal that sensor acquisition produces behind the train passage signal is through the VD5026 output coding information and through TWH630 transmitter module wireless transmission, and the TWH631 receiver module receives this coded message after VD5027 decoding and output train right of way signal are delivered to microprocessor.
With reference to the accompanying drawings 3, the audio signal sample device mainly is made up of identical Electret condenser microphone M1 and the audio signal sample circuit of two covers.Two cover Electret condenser microphones are installed in the homonymy of rail and convert the train passage aud. snl. to electric signal, deliver to the power amplifier of forming by LM386 after the pre-amplification circuit that this electric signal is made up of aerotron N1 amplifies and carry out power gain, and deliver to A/D converter through RC bandpass filter and shaping circuit.
With reference to the accompanying drawings 4, during train passage, the train passage signal of signal picker collection is delivered to 7 of 16C17 micro controller system respectively, 11,12,17 ends are after A/D conversion and analysis and judgement, as be confirmed to be the train passage signal, then from 1,2,3, the geocoding that 18 ends read in forms information code and through 6 end driving N 2 and the work of FS transmitter module, the train passage signal is promptly by wireless transmission.Meanwhile, driving channel self check time delay circuit through 9,10 ends resets.
With reference to the accompanying drawings 6, signal picker, the power supply of A/D converter, microprocessor and coded transmitter is made up of solar cell and storage battery and mu balanced circuit.When solar radiation was arranged, solar cell charged a battery on the one hand, was again circuit supply on the other hand; At cloudy day or night, be circuit supply then by storage battery.The storage battery output voltage is 6V, through the MAX667 voltage stabilizing, is circuit supply by 2 end output+5V voltages.R1 R2 forms bleeder circuit in addition, by 7 ends output undervoltage warning signal, is connected to the undervoltage warning input end of micro controller system.
With reference to the accompanying drawings 1, the signal in the utility model receives annunciator and mainly comprises signal receiver, demoder, microprocessor, annunciator and power supply and be installed on place, unmanned road junction.After signal receiver receives the train passage signal of acquisition of signal projector wireless transmission, by demoder decode and microprocessor carry out analyzing and processing and by annunciator send sound or visual alarm.Power supply is by solar cell and storage battery and mu balanced circuit is formed and provide DC regulated power supply for signal receiver, demoder, microprocessor and annunciator.
