Description
Technical Field
The utility model relates to the field of railway lighting circuits, in particular to a full-flow integral hot standby control circuit in a railway LED signal lighting device.
Background
Conventional civil lighting, traffic signal lighting and the like are all lighted by a single lamp wire. Considering the high safety important characteristic of high-level railway signal lighting, the railway department requires that the auxiliary lamp wire circuit is checked simultaneously under the condition that the main lamp wire is normally lighted, so as to ensure that the auxiliary lamp wire circuit can reliably light up when the main lamp wire is suddenly damaged to turn off the lamp, thereby ensuring that the railway signal control command system can continuously and normally run for 24 hours.
For decades, railway signal lighting has been bulb-type lighting. The lamp bulb is simpler to light up, namely, the main lamp filament and the auxiliary lamp filament are 2 filaments and 1 common loop, so that the railway signal lighting adapter can conveniently and online check the sound conditions of the auxiliary wire lead and the auxiliary lamp wire (or the auxiliary lamp bulb) directly through the auxiliary wire terminal. If the auxiliary wire lead or the auxiliary wire is detected to be damaged, the wire breakage alarm condition is fed back to an indoor signal building through an input AC220V power supply or a special wire breakage alarm feedback line by the connected railway signal lighting adapter immediately, and the wire breakage alarm lamp position is recorded in real time to inform railway signal maintainers to immediately go to replacement and repair so as to prevent the occurrence of malignant railway signal faults of simultaneously extinguishing the main and auxiliary wires.
With the high-speed development of modern technology, the LED with ultra-high brightness and long service life has been rapidly popularized and applied in large quantity. However, the internal auxiliary filament LED light-emitting chip, the power supply, the control circuit and the like in the railway LED signal lighting device are more complex than those of a traditional signal bulb, and the main and auxiliary power supplies and the control circuits for forming LED light emission are more complex than those of a common signal bulb. Therefore, in the existing railway LED signal lighting devices at home and abroad, on the one hand, only the simple external auxiliary filament inspection of two external lead wires of the auxiliary filament and the return wire between the railway LED signal lighting device and the two devices of the railway signal lighting adapter can be realized, but the complete inspection of the most-closed internal auxiliary filament circuit in the LED signal lighting device cannot be realized, namely, the integrity of the most-closed internal auxiliary filament LED light emitting chip and the control core main circuit in the LED signal lighting device cannot be subjected to the online safety inspection. On the other hand, because the LED lamp is paralyzed and misled by the multipath reliability of the LED light-emitting chips, in the current normal signal lighting circuits of all the main and auxiliary LED filaments at home and abroad, the whole hot standby design is not carried out on the common and relatively complex superposition of the LED light-emitting chips and the main body control circuit. For the two reasons, the emergency situation happens when the railway LED signal lighting device is normally turned on and turned off, and the emergency stop risk of the train in normal running occurs because the railway LED signal lighting device suddenly fails to turn off the light.
Because the potential safety hazards in the two aspects are located, the technical management departments of railway headquarters and railway authorities are involved, the railway LED signal lighting device products are not interested in the excellent characteristics of long service life and striking, but are attractive to the potential safety hazards of the railway LED signal lighting device, namely, the railway LED signal lighting device can be suddenly extinguished without any reason, so that the application of the railway LED signal lighting device is not fully popularized so far in the railway signal lighting field, and the railway LED signal lighting device is obviously lagged behind the LED lighting era popularized in the whole society.
