Description
Technical field
The present invention relates to a kind of operation monitoring device, particularly relate to a kind of locomotive that can prevent and cross the locomotive safety running auxiliary monitoring device of rail yard closed condition shunting signal.
Background technology
The ground shunting signal of rail yard is the visual signal machine that utilizes light to show at present, carry out the trainman of shunting service or commentaries on classics line in the field, station, the lamp colr that the shunting signal of seeing according to vision shows is handled locomotive by the indication of signal light color and is being carried out shunting service work.
Because shunting signal is dwarf signal substantially, the influence of stood field wire road curve or visual angle and weather, the time have trainman's misidentification shunting signal to show lamp colr, cause and cross the shunting signal of closing.
Though the safe train operation monitor has been equipped at locomotive by the railway system, but because the information that can not gather the shunting signal wigwag, so can not monitor the locomotive that carries out shunting service, therefore the shunting signal that a lot of locomotives are crossed closed condition has taken place in the railway system, has caused the serious accidents of a series of consequences such as crowded bad track trouble, locomotive off-line, collision conflict.
Summary of the invention
For preventing that locomotive from crossing the shunting signal of closed condition, the invention provides a kind of infrared signal transmission and camera of utilizing and scan the monitor that obtains shunting signal information.This monitor can receiving infrared-ray signal the information of transmission and camera scanning shunting signal, can be when trainman's misidentification shunting signal, and locomotive implemented the emergency braking measure in time to alarm driver, can guarantee the locomotive safety running of shunting service or commentaries on classics line.
The ground shunting signal of rail yard is the wigwag machine of dwarf forms substantially at present, and bulb is 25 watts, uses the 12V alternating current, and display mode is a signal blue or month white light light.Show the blue lamp light time, forbid that locomotive crosses; Show a month white light light time, permit locomotive and pass through.If misidentification appears in the driver, when the manipulation locomotive is crossed the shunting signal that shows blue light, will have an accident.
Can see the locomotive that carries out shunting service or commentaries on classics line in the field, station here, definitely can not cross the shunting signal that shows blue light, could guarantee the safety of shunting locomotive and vehicle.
What the present invention solved that its problem takes is to utilize infrared signal transmission and infrared photography to scan, and obtains the technical scheme of shunting signal lamp colr information:
1, infrared signal transmission:
Install an infrared projector additional at the ground of rail yard shunting signal, it gathers the information of shunting signal wigwag, according to the information of shunting signal lamp colr, the infrared signal that utilizes microprocessor to set different frequency is launched to the locomotive direction; Add the running safety monitoring device on locomotive, connecting infrared signal receiver and infrared camera, the control capsule of monitor has read-out and loud speaker, gathers the speed signal of locomotive, control sudden stop circuit.After the infrared ray signal receiver receives ground-surface infrared signal; the microprocessor of auxiliary monitoring device is deciphered identification to the frequency of infrared signal; when if the frequency of identification is the information of the blue light of shunting signal; the microprocessor of monitor starts the defense controls pattern; when the driver misidentification occurs and handles locomotive and prepare to cross shunting signal; the monitor control capsule is immediately to alarm driver; as the do not take safety measures circuit of monitor microprocessor conducting sudden stop of driver; locomotive is implemented emergency braking, can guarantee that locomotive do not cross the shunting signal that shows blue light.
2, infrared photography scanning:
When ground-surface infrared projector breaks down, infrared photography can scan the information of shunting signal, the DSP microprocessor of auxiliary monitoring device is deciphered identification to the shunting signal graphical information that scans, and auxiliary monitoring device is realized above-mentioned controllable function equally.
The invention has the beneficial effects as follows, the auxiliary monitoring device of locomotive utilizes infrared signal transmission and infrared camera scanning to obtain the information of shunting signal lamp colr, job safety to locomotive is monitored, and has solved the problem that the message feedback of shunting signal lamp colr is arrived the locomotive auxiliary monitoring device.
