Abstract
The invention provides a railway signal phase-lock loop sampling and autognosis control system. Based on an existing railway signal controller, the railway signal phase-lock loop sampling and autognosis control system adds devices such as a railway barrier detection launcher. Through unique logic circuit designs, on the condition that an original signal control principle of a railway is not influenced, statuses of railway signal lamps are modified forcibly according to the situation that the railway has unusual barriers, and display statuses of the signal lamps are red when the railway has barriers and unusual conditions. The railway signal phase-lock loop sampling and autognosis control system has storage system, so real-time storage of basic information of the barriers and the unusual conditions can be stored, and information that the barriers and the unusual conditions are shown can be sent to a railway control center and trains which are operated in a given range, and preparation work of answering the barriers is reminded. The railway signal phase-lock loop sampling and autognosis control system innovates a way of automatic correction and treatment of signals when the railway has barriers and unusual conditions, and safety of train running is improved. The railway signal phase-lock loop sampling and autognosis control system can automatically collect and timely identify the barriers and unusual conditions signals. The railway signal phase-lock loop sampling and autognosis control system is simple in system, reliable, and strong in practicability.
Description
Technical study
This research belongs to the research of railway signal phase-locked loop sampling autodiagnosis control system.Be characterised in that control structure is simple, the signal lamp state is forced conversion, works simultaneously with railway self signal lamp control system, can not affect the normal operation of railway self signal lamp control system, and self has data storage function system.
Background technology
At present, the Frequent Accidents such as rear-end accidents of rail train, collision, according to afterwards technology groups investigation discovery, most accidents all occur unusual owing to railway signal control system.The control system of railway signal itself just according to the running condition of vehicle on the net inner loop-line arrange each signal etc. state guiding train operation, wait for, stop, " obstacle " system occurring for cause specific can automatically not identify, control, can only be judged according to actual conditions by the staff, slightly having hesitates will lead to a disaster.This research is to be to evade a kind of " the railway signal phase-locked loop sampling autodiagnosis control system " that the generation of accident is invented for the situation that " obstacle " appears in Along Railway.It can be surveyed sensor-based system and detected on the railway whether obstacle is arranged by railway signal lamp the place ahead quality testing of placing obstacles, send the state that control information changes signal lamp by force if there is obstacle by this system, this system can not affect the normal operation of the control system of railway own when having obstacle.
Summary of the invention
The present invention mainly is that (comprising train stops to the situation that obstacle is arranged on the railway, the states such as jogging), detect on the railway whether have obstacle by the detection of obstacles sensor-based system, if at the safety zone that arranges with the interior obstacle that occurs, checking system can detect obstacle, detection information is sent to the railway barrier detector, this instrument sends control information to signal lamp, the state of revising signal lamp is red, and the train handling personnel that move in railway signal control operation department and the setting area simultaneously send alerting signal, and this signal comprises the obstacle particular location, leading dimensions, the relevant informations such as state.This invention is for being parallel to autonomous cruise speed system in one beyond railway self control system, it install the normal operation that can not affect railway self control system additional, redness and the green state of its control signal lamp are not done control to other light color signal (amber light, blue lamp, white lamp, red white lamp, red blue lamp).Railway signal phase-locked loop sampling autodiagnosis control system has the data storage functions such as video, audio frequency, and mode of operation that can real time recording self particularly can keep storage to the relevant information of obstacle on the railway.
Characteristics of the present invention
1, to analysis, storage, the transmission of obstacle essential information, to the prevention of accident and afterwards evidence obtaining authentic communication is provided;
When 2, on the railway obstacle being arranged, the state that system's meeting automatic forced is revised signal lamp can effectively avoid occuring the accidents such as train from overtaking collision, collision to red;
3, this system can send alerting signal with the train handling personnel that the mode of transmission over radio is moved the obstacle essential information in railway signal control operation department and the setting area when revising the signal lamp state;
4, this system is simple, reliable, practical.

The specific embodiment
" railway signal phase-locked loop sampling autodiagnosis control system " is based on detection, analysis to obstacle on the railway, send information by the railway barrier detector, mandatory modification signal lamp state is to red status, make at the train of setting regions operation and control in advance train, avoid knocking into the back the generation of the accidents such as train colliding.The implementation content is:
1, the setting regions in signal lamp the place ahead arranges a plurality of detection of obstacles sensors.
2, the information that detects of detection of obstacles sensor is through I/O conversion input video treater, and this treater is through pattern algorithm computing (Fig. 3, Fig. 4), calculates the leading dimensions of obstacle and status (stop, jogging etc.),
3, obstacle relative dimensions result of calculation is input to the railway barrier detector, for next step state of revising signal lamp provides direct basis (Fig. 2), simultaneously with wireless transmission method information is occured for the train handling personnel (Fig. 5) that move, and this information is stored in the holder of inside to railway signal control operation department and setting area.
4, extract the B end of control signal state sample (Fig. 6) input Exclusive-OR gate (XOR gate) from the railway signal control device, input the A end of Exclusive-OR gate (XOR gate) through the control signal of railway barrier detector output, export (Fig. 1) through the controlled signal of Exclusive-OR gate (XOR gate) logical calculated by the L end.
5, install railway signal phase-locked loop sampling autodiagnosis control system additional after, the mode of operation principle of signal lamp is as follows:
Annotate:
When 1. there was obstacle in signal lamp the place ahead, railway barrier detector output control signal was high potential (1), and the output control signal is active potential (0) during clear;
Railway signal control device output control signal was high some position (1) when 2. train had plan by this signal lamp, and the output control signal is (0) during by the signal lamp plan without train.
