Description
Technical field
The present invention relates to a kind of electro-illumination utensil, particularly a kind of have digital automatic detection function, the numerous LED light-emitting diodes of set in one, as the LED signal lamp of light emitting source.
Background technology
Railway signal lamp is the indispensable facility that ensures railroad train and the normal operation of on-road vehicle, for a long time, all adopt high-power filament lamp as light source, be equipped with colored lens and constitute red, green, yellow signal lamp.In order to improve the functional reliability of bulb, in bulb, be equipped with mariages.But the overall energy consumption height of filament lamp, work life weak point need often monitoring cross-check sum periodic replacement, thereby the line service amount are very big, cost is higher.Luminosity scale that numerous LED collection of leds that energy consumption is extremely low when having occurred with work are in recent years made replaces with the signal lamp of filament bulb as light source, effectively reduces energy consumption, has prolonged service life of signal lamp.But in actual use, luminosity scale is concatenated into a branch road by several LED light-emitting diodes usually and then several branch roads is formed in parallel, according to Ministry of Railways's industry standard regulation, when having the 1/3LED light-emitting diode not work on the luminosity scale, just should report to the police immediately, overhaul, for this reason, be necessary the mode of operation of luminosity scale is carried out Continuous Tracking and monitoring.All adopt the analog quantity method of inspection at present, promptly judge that according to the working current total value size of luminosity scale wherein having what light-emitting diodes to be in extinguishes state.In order to obtain than the exact current value, adopted the signal ignition device of high input impedance, simultaneously, for voltage stabilizing, input end at the signal ignition device is provided with current rectifying and wave filtering circuit, after handling like this, the thing followed is to have caused the energy accumulation of interfering signal on filter capacitor in voltage stabilizing again, particularly, cause the wrong shinny of signal lamp easily, become the accident potential risk at electrified section, and, it is not high to judge that according to the analog quantity current value LED light-emitting diode that has on earth on the LED luminosity scale on how many branch roads is in the reliability that extinguishes state, just in case take place to mislead signal, can bring immeasurable economic loss to railway transportation surely.
Summary of the invention
The objective of the invention is to provide that a kind of antijamming capability is strong, functional reliability is high, have digital automatic detection function, the novel LED signal lamp of low in energy consumption, long working life.
The present invention is achieved in that the LED signal lamp with digital automatic detection function mainly is made up of housing, led light source member and electric prosecution working part, the led light source member is arranged on the port of housing, and electric prosecution working part is arranged on the inside of housing.Wherein: on housing, also be provided with and connect member outside electric; The led light source member is compiled by numerous LED light-emitting diodes and convex lens and forms; Include the lightning prevention circuit that constitutes by discharge bulb GDT, pulse choking coil L, piezoresistor MOV in the electric prosecution working part, the LED pull up circuit and the cpu central processing unit that constitute by several electric branch road parallel connections that form by several LED light-emitting diodes and current-limiting resistor R serial connection respectively, simultaneously be provided with the sampling output line at each current-limiting resistor R and adjacent LED light-emitting diode termination place, the sampling output line on each branch road is electrically connected with the input end of cpu central processing unit respectively.
In working order down, the low resistance signal transformer that lightning prevention circuit in the described electric prosecution working part connects outside electric in member and the railway signal automatic control system is electrically connected, and the mouth of described cpu central processing unit connects outside electric that inspection center in member and the railway signal automatic control system is electrically connected, and center and warning circuit are electrically connected after testing.
The LED signal lamp that has digital automatic detection function based on the present invention of above-mentioned design, because the low resistance signal transformer that tradition is used in its input end and the railway signal automatic control system is electrically connected, exempted to use signal ignition device ad hoc in the prior art, and the required red, green, yellow three kinds of colors of signal aspect and indication can directly be made of the LED light-emitting diode of different color, need not ad hoc colored convex lens, help reducing deployment cost; Again since signal transformer this as low input impedance, the interference voltage that might scurry into generation is very low, and there is not current rectifying and wave filtering circuit in the circuit, the situation of cond energy storage in the prior art, initiation spurious signal can not take place, can not cause the overdue bright of LED light-emitting diode by the low voltage of disturbing generation, thereby improve the reliability of signal lamp work greatly; In addition, on every branch road, be provided with sampling point, when the LED light-emitting diode on the branch road is working properly, the sampled signal of sending on this branch road is the fixed level value, when the LED light-emitting diode on the branch road opens circuit, sampled level value on this branch road is lower than the fixed level value, when the LED light-emitting diodes tube short circuit on the branch road, sampled level value on this branch road is higher than the fixed level value, so, the incoming signal that cpu central processing unit receives is a digital signal level, just can judge the mode of operation of LED light-emitting diode on each electric branch road in view of the above easily, and analysis result in time is sent to inspection center in the railway signal automatic control system, in case find abnormal conditions, inspection center promptly controls warning circuit work, send alerting signal, help in time eliminating safety hazard.And carry out the continuous monitoring task by cpu central processing unit, fault detection is very simple and convenient, functional reliability is strong.Thereby the LED signal lamp with digital automatic detection function of the present utility model is that a kind of utmost point is suitable for energy-saving, highly reliable, the ideal type signal lamp that the railway system uses, and has significant technical advance, very good economy and extremely strong practicality.
