Description
Technical field
The present invention relates to Lightning Prevention Technique field, particularly relate to the fault detection method of the Anti-surging device in a kind of train automatic controlling system.
Background technology
Train automatic controlling system needs the input switch amount of collection vehicle.These switching values are most important to whole system, if gather mistake will affect the control information of robot control system(RCS) output error, the accident such as likely cause casualties.These switching values introduced by vehicle will inevitably with the such as undesired signal such as surge, high frequency, in order to guarantee to collect correct input switch amount, usual needs design EMC (ElectroMagneticCompatibility, electromagnetic compatibility) protection circuit in input Acquisition Circuit.Anti-surging device in EMC protection circuit may breakdownly lose efficacy in actual applications.The fault of Anti-surging device may cause the switching value collecting mistake equally, even burning apparatus.Therefore need to carry out fault detect to the Anti-surging device in input Acquisition Circuit.
In prior art, conventional has following two kinds to the method that Anti-surging device fault detects:
First method is: add direct supply at input Acquisition Circuit common port, when there being Anti-surging shorted devices to lose efficacy, failure of removal acquisition circuit will collect fault-signal.
Second method is: first input Acquisition Circuit provides Dynamic Signal, and what collect when switch closes also will be Dynamic Signal.When inputting Acquisition Circuit and breaking down as the open circuit of Anti-surging device or short circuit, collection terminal will collect fixed level, thus decision circuitry Anti-surging device failure.
Visible by foregoing description, in first method, need to add the components and parts such as direct supply, optical relay in input Acquisition Circuit, and be placed with source current chip and will produce certain impact to EMC safeguard function in input Acquisition Circuit, there is certain failure risk in the components and parts simultaneously added, affects the availability of whole system.In the second approach, make use of Dynamic Signal collection, but collect fixed level when can only ensure components and parts fault in input Acquisition Circuit, if External cable generation swinging cross, will take for is that switch closes, and collects error message.
Summary of the invention
The invention provides the fault detection method of the Anti-surging device in a kind of train automatic controlling system, fault detect can be carried out to Anti-surging device, and, the availability of whole system can not be affected, outside swinging cross can not be produced.
The invention provides the fault detection method of the Anti-surging device in a kind of train automatic controlling system, described method comprises:
By the signal of the earth in a road input Acquisition Circuit Acquisition Circuit;
Whether that detects the output terminal of described input Acquisition Circuit has signal;
If there is signal, then Anti-surging device is short-circuited;
If when not having signal, then Anti-surging device is not short-circuited.
Further, the described signal passing through the earth in a road input Acquisition Circuit Acquisition Circuit, specifically comprises:
The input end of a described road input Acquisition Circuit is connected to the earth in circuit.
By the fault detection method of the Anti-surging device in a kind of train automatic controlling system provided by the invention, carry out fault detect by train automatic controlling system Zhong mono-tunnel input Acquisition Circuit to Anti-surging device not need to add the availability that new components and parts can not affect train automatic controlling system, outside swinging cross can not be produced.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the fault detection method process flow diagram of the Anti-surging device in a kind of train automatic controlling system of providing of the embodiment of the present invention.
Embodiment
For making the object of the embodiment of the present invention, technical scheme and advantage clearly; below in conjunction with the accompanying drawing in the embodiment of the present invention; technical scheme in the embodiment of the present invention is clearly and completely described; obviously; described embodiment is the present invention's part embodiment, instead of whole embodiments, based on the embodiment in the present invention; the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of protection of the invention.
Embodiments provide the fault detection method of the Anti-surging device in a kind of train automatic controlling system, see Fig. 1, the method comprises:
Step 101: by the signal of the earth in a road input Acquisition Circuit Acquisition Circuit;
Step 102: whether that detects the output terminal of this input Acquisition Circuit has signal;
Step 103: if there is signal, then Anti-surging device is short-circuited;
Step 104: if when not having signal, then Anti-surging device is not short-circuited.
Wherein, by the signal of the earth in a road input Acquisition Circuit Acquisition Circuit, specifically comprise:
The input end of Jiang Gai mono-tunnel input Acquisition Circuit is connected to the earth in circuit.
It should be noted that: in train automatic controlling system, have multichannel to input Acquisition Circuit, therefrom select to come and detect the fault of Anti-surging device.
Insurance is added, every bar branch circuit parallel connection two-way protection device at the branch road of Anti-surging device.Input filter capacitor is put to Anti-surging device, surging prevention is carried out to input signal cable and then carries out capacitor filtering.Meanwhile, in order to reduce the complexity of circuit and effectively prevent input circuit swinging cross, make multichannel input Acquisition Circuit and share a road INPUT_GND end and EARTH end.
When the breakdown inefficacy of the Anti-surging device in the first input Acquisition Circuit, the outside input quantity signal of this first input Acquisition Circuit can seal in this in the second input Acquisition Circuit of detection failure through the earth of oversampling circuit, the signal imported after now can collecting the Anti-surging device breakdown of upper end on the output terminal of the second input Acquisition Circuit, can determine there is the breakdown short-circuit failure of Anti-surging device in the first input acquisition circuit thus, if the output terminal of the second input Acquisition Circuit does not collect the signal of the breakdown rear importing of Anti-surging device of upper end, then Anti-surging device does not puncture.Wherein, the second input detecting circuit has only been used as the fault detect of Anti-surging device, is not used as actual input signal collection, so when Anti-surging device breakdown lost efficacy the outside actual input quantity of importing, can not impact the input collection result of reality.
Visible by foregoing description, the embodiment of the present invention has following beneficial effect:
The fault detection method of the Anti-surging device in a kind of train automatic controlling system provided by the embodiment of the present invention, carry out fault detect by train automatic controlling system Zhong mono-tunnel input Acquisition Circuit to Anti-surging device not need to add the availability that new components and parts can not affect train automatic controlling system, outside swinging cross can not be produced.
