Abstract
The invention discloses a filament burnout alarm device which comprises a signal logic unit, a lamp lighting unit, a signal bulb, an acquisition device, a monitoring host, a train command center, a filament relay, a first fuse and a second fuse. The filament burnout alarm device has the advantages that the cost is low, and thus the investment can be saved; weak electronic elements are not arranged inside the acquisition device and are all packaged in a flame-retardant box, and thus the moisture resistance and lightning protection performance are good; the filament burnout alarm device is suitable for alpine and plateau regions and has more obvious effects when used in the environment of multiple thunderstorm weather days in the south; and the acquisition device has cold filament preheating and buffering functions, is used for prolonging the service life of the bulb and has a subsidiary filament early burnout alarming function, thereby compensating for deficiencies of the conventional lamp lighting unit.
Description
Technical field
The present invention relates to a kind of warning device, particularly relate to a kind of alarm for burnout of filaments device.
Background technology
Semaphore is commander and ensures the most important signalling arrangement of safe train operation, and the operating state of reply semaphore is monitored in real time, and provides warning message.
Traditional railway signal filament conversion warning system adopts relay mode, carries out filament switching and warning.When main filament fracture of wire, by the actuating of relay, semaphore is switched to paranema, connects warning circuit simultaneously, utilize alarm cable to be transferred to train command centre, notify staff's fracture of wire situation.There is following defect in this mode:
1, must alarm cable be set up, not only increase construction investment, and be unfavorable for construction and installation and regular maintenance.
2, can not to report to the police particular location, must be investigated by frame by staff, be not easy to troubleshooting.
3, during auxiliary filament elder generation fracture of wire, cannot realize reporting to the police, now main filament fracture of wire, will cause semaphore to turn off the light, and no signal shows, and directly jeopardizes traffic safety and reduces efficiency of driving a vehicle.
When main filament fracture of wire, when switching to auxiliary filament, voltage can strengthen, and the voltage of impact exists cold silk to auxiliary filament to be impacted, and affects the useful life of auxiliary filament.
Summary of the invention
Object of the present invention is just to provide a kind of alarm for burnout of filaments device to solve the problem.
The present invention is achieved through the following technical solutions above-mentioned purpose:
The present invention includes signal logic unit, lighting unit, signal lamp, harvester, monitoring main frame, train command centre, filament relay, first fuse and the second fuse, described first fuse is connected with 220V power supply respectively with described second fuse, described first fuse is connected after described filament relay and is connected with described signal logic unit, described second fuse is connected with described signal logic unit, first end and second end of described signal logic unit and described lighting power supply are connected, 3rd end of described lighting unit and described 4th end are connected with the first end of described signal lamp board and the second end respectively, the five terminal of described lighting unit is connected with the control end of described signal lamp, the alarm signal output ends of described lighting unit is connected with the signal output part of described harvester, the signal output part of described harvester is connected with the signal input part of described detection main frame, the signal output part of described monitoring main frame is connected with the signal input part of described train command centre.
Beneficial effect of the present invention is:
1) use this device need not consider to lay special cable transmission heart yearn, can reduce investment outlay; Especially newly-built station is without budget two core alarm cable, and easy construction, the transformation of existing station also just changes one outdoor, each lamp position of lighting unit, size and traditional lighting unit size completely the same, directly can replace, increase harvester very simple with monitoring main frame distribution;
2) alarm host machine adopts independently warning circuit, built-in check, check to compare, therefore warning message absolutely accurate, there is addressing circuit easily produce and misrepresent deliberately wrong report unlike traditional warning;
3) harvester inside does not have faint electronic component, all be encapsulated in a fire-retardant box, therefore moistureproof, lightning protection properties is relatively good, also high and cold, highlands is applicable to, especially use more obvious under the environment that southern thunderstorm weather is more, and product comes into operation so far on Qinghai-Tibet Railway line, all reflect that Performance comparision is stablized;
4) harvester has cold silk preheating, pooling feature, for extending bulb service life; And have paranema first disconnected warning function, make up the weak point of traditional lighting unit, if fault occurs on the shunting signal relevant with main track train route or industrial siding, now paranema first breaks, main silk is disconnected will turn off the light, with regard to entail dangers to train safe, and severe jamming railway transportation normal continuous.This phenomenon scene has and occurred;
5) monitoring main frame not only can the operating current of Real-Time Monitoring filament monitoring relay, but also can the whole loop of Real-Time Monitoring intact, comprises open circuit, break monitoring; Be conducive to failture evacuation;
6) alarm host machine can be connected with microcomputer monitoring, is convenient to control its operating state.
