Description
Affiliated technical field
The utility model is a kind of railway signaling display system.In being suitable for China railways interval, standing, the types of signals equipment dress such as industrial siding, road junction uses.
Transportation by railroad for a long time facts have proved, the quality of railway signals equipment technical feature, the height of reliable degree are directly connected to China Railway traffic safety.As the signal apparatus of train traffic control order, should constantly adopt modern high technology, develop novel railway signal more advanced, safety and reliability and show and failure warning system, to adapt to the needs of China railways modernization construction.
Background technology
Existing similar device, adopts low-power LED light source and the design of traditional sound and light alarm, as long as there is a luminotron fault in practice, is connected on the luminotron not breaking down in loop and also will loses efficacy thereupon, directly affects the normal display effect of signal.In addition, the signal causing because its noiseproof feature is bad disorderly shows that phenomenon happens occasionally, and directly jeopardizes railway operation safety.Moreover common acousto-optic alarm design is taked in the fault alarm design of existing control circuit for light source, make operator on duty can not confirm rapidly the particular location of fault, warning effect still can not meet the on-the-spot actual needs of transport.What is more, along with the prolongation of service time, luminotron temperature raises, output characteristics variation, cause forming vicious cycle between electric current and temperature rise, and then cause light source colour purity to be tending towards deteriorated with fast speed, thus bring many potential safety hazards to transportation by railroad, be difficult to adapt to safe, heavily loaded, the fast-developing needs of China Railway.
Summary of the invention
The light pipe fault causing in order to overcome low power LED tandem working mode, not also Problem of Failure thereupon of the light pipe of fault, the utility model has adopted large-power light-emitting diodes monitoring automatically in parallel and uninterrupted working method; The undesirable problem of warning effect causing in order to overcome fault alarm analog sample out of true, the utility model has adopted central processing unit dynamic monitoring and digital display technique; Raise and cause circuit output characteristics variation, signal to show the abnormal disadvantage of colourity with temperature in order to overcome working current, the utility model has adopted the field effect control technology with electric current and temperature self-adaptation performance; The signal error demonstration problem causing in order to overcome outside electromagnetic interference, the utility model has adopted the cabinet with electro-magnetic screen function to cut off inside and outside electromagnetic connection; The random demonstration problem of signal causing in order to overcome surge voltage, the utility model has adopted laterally and vertical clutter combined type anti-interference and low-and high-frequency capacitor filtering technology; In order to solve the security protection problem of short trouble, the utility model has adopted from flow recovery guard technology; The circuit malfunction problem causing in order to overcome induction damage to crops caused by thunder, the utility model has adopted effluve and quick Surge suppression combination shocking preventing technology; Can not determine the problem of particular location and trouble light light color in order to overcome traditional sound and light alarm information, the utility model has adopted microprocessor pulse decoding technology, the technology can be directly by the outdoor signal plane No. code breaking down and lamp position, and Real-time Feedback is to the alarm terminal that is positioned at signal value class chamber.
