[specific embodiment]
To keep the purposes, technical schemes and advantages of the embodiment of the present disclosure clearer, below in conjunction with the embodiment of the present disclosure
In attached drawing, the technical solution in the embodiment of the present disclosure is clearly and completely described, it is clear that described embodiment is
Disclosure a part of the embodiment, instead of all the embodiments.Based on the embodiment in the disclosure, those of ordinary skill in the art
Whole other embodiments obtained without creative efforts, belong to the range of disclosure protection.
In addition, the terms "and/or", only a kind of incidence relation for describing affiliated partner, indicates may exist
Three kinds of relationships, for example, A and/or B, can indicate: individualism A exists simultaneously A and B, these three situations of individualism B.Separately
Outside, character "/" herein typicallys represent the relationship that forward-backward correlation object is a kind of "or".
Fig. 1 is shown can be in the schematic diagram for the Example Operating Environment 100 for wherein realizing embodiment of the disclosure.It is transporting
It include MSS station machine 102 and switch indication circuital current collector 106 in row environment 100.The station MSS machine 102 passes through MSS machine
Cabinet 104 is connect with switch indication circuital current collector 106.Switch indication circuital current collector 106 is for acquiring track switch
Indication circuit current information.Although illustrating only a switch indication circuital current collector 106 in Fig. 1, ring is run
It may include multiple switch indication circuital current collectors 106 in border 100.
Switch indication circuital current collector 106 will pass through MSS cabinet 104 and send out after switch indication circuital current information collection
Give the station MSS machine 102.Wherein, the switch indication circuital current information includes transformer output current, relay branch current
And diode branch electric current.
The MSS station machine 102 indicates failure with the presence or absence of mistake according to the switch indication circuital current information diagnosis track switch
And lose expression fault type.
Although switch indication circuital current collector 106 is for acquiring transformer output current, relay branch in Fig. 1
Road electric current and diode branch electric current, but the disclosure is not limited to this.In the other embodiments of the disclosure, switch indication electricity
Road current collector 106 can be independent multiple collectors, for acquiring transformer output current, relay branch electricity respectively
Stream and diode branch electric current.
Fig. 2 shows can be in the exemplary exchange switch normal indication simplification figure for wherein realizing embodiment of the disclosure.
By taking the exchange switch normal indication simplification figure of -9 railway switch control of five-wire system ZD (J) as an example, -9 goat of ZD (J) is
Yard is concentrated for Railway Electric, can be used to change track switch and open direction, locking point tongue reflects point tongue position shape
State.Slowed down using ball-screw, has the characteristics that high efficiency；Motor uses three-phase alternating current 380V power supply, cable single command range
Long, failure rate is low；Contact system uses beryllium-bronze break group and copper-tungsten movable contact ring, stretches out rod piece chromium plating antirust,
At stretching with polyethylene plug-hole circle and asphalt felt dustband support and it is dust-proof.Performance indexes meets speed-raising section track switch and its
The needs of his track switch conversion.
The switch indication circuit (by taking normal indication circuit as an example) is made of two branches, indicates relay and rectification two
Pole pipe category parallel-connection structure, changes pervious cascaded structure, and eliminate capacitor, improves reliability；Electricity has been sealed in circuit
Machine coil also has checked electrical-coil while checking indication circuit, can find motor problem in time.
Because transformer output is 110V AC power source, therefore circuit analysis need to be carried out by the positive and negative half-wave of alternating current.
Collection point BB indication transformer exports electric current；Collection point JDQZL indicates relay branch current；Collection point EJGZL
Indicate diode branch electric current；Switch indication circuital current collector 106 by collection point BB to switch machine indication circuit, adopt
Collection point JDQZL, collection point EJGZL carry out transformer output current, the relay branch current and two that current acquisition obtains respectively
Pole pipe branch current.
When sine ac power supply positive half-wave, it is assumed that the lower part of transformer side exports, i.e., X1 terminal is positive voltage.Relay
DBJ is picked up, meanwhile, in the diode branch of relay DBJ coils from parallel connection of coils, rectifier diode Z reversely ends, therefore electric current is basic
It is zero.
When the negative half-wave of sine ac power supply, it is assumed that the lower part of transformer side exports, i.e., X1 terminal is negative voltage.In relay
In device branch and diode branch, sense of current is contrary, since at this moment rectifier diode Z is in forward conduction state, therefore two
The impedance ratio relay branch impedance of pole pipe branch is much smaller, all overwhelming majority of electric current at this time by being flowed through in diode branch,
The negative half period of electric current is then able to detect that on X2；In addition the induction reactance of relay DBJ coil is very big, and slow with certain electric current
Effect, thus relay DBJ coil is able to maintain and is picking up state.
Picking up for the relay DBJ indicates that track switch is positioning.
For diode branch, when X1 terminal is positive voltage, EJGZL can't detect electric current；When X1 terminal be negative voltage,
EJGZL detects the negative half period of electric current；
For relay branch, no matter X1 terminal is positive voltage or negative voltage, and JDQZL can detect the electricity of sine wave
Stream；
And the electric current BB of the collection point acquisition of indication transformer is diode branch current EJGZL and relay branch current
The sum of JDQZL.

Device exports electric current, and curve 2 is relay branch current, and curve 3 is diode branch current.
It is similar with normal indication for the exchange switch reverse indication of -9 railway switch control of five-wire system ZD (J), herein no longer
It repeats.
