Specific embodiment
Embodiment one
The present invention provides a kind of portable SA brake switch testers, suitable for the Site Detection of magnetic-levitation train SA.Inside the tester
Power supply signal exports, and is failure intuitively to show the state and performance of tetra- travel switches of SA through switch feedback to indicator light
Specific failure cause, which is quickly searched, when diagnosis and repairing provides foundation.
As shown in Figure 1, the portable SA testers of the present invention include two parts, respectively tester ontology and connection electricity
Cable assembly.Tester ontology style be portable box form, box body waterproof and dustproof.Box body panel is equipped with manipulation selecting switch and refers to
Show lamp, if box body side is also equipped with adapter stem, external power supply and signal cable can be connected（Specific cable is not shown, with arrow
Head signal）；Tester power supply is by external AC220V or internal lithium battery power supplies.The tester weight of this example is 1.5 kilograms.
The tester can be powered by external 220V power supplys or internal battery, by the toggle switch on control panel,
Power supply signal is sent by connector to the limit switch contact inside tested measurement equipment, then feed back to the indicator light of tester,
Indicator light is bright or goes out, and can reflect the state of limit switch.
As shown in Fig. 2, limit switch has 4, respectively K1, K2, D1, D2 inside SA equipment.Limit switch K1 contacts with
C/B needles connection at connector X0001 sockets, limit switch K2 are connect with the C/B needles at connector X0003 sockets, and limiting is opened
It closes D1 to connect with the J/H needles at connector X0003 sockets, limit switch D2 is connect with the E/F needles at connector X0003 sockets.
When not extended out by stream boots of SA, limit switch D1 are closed state, and limit switch K1, K2, D2 are off-state.SA by stream boots
After stretching, limit switch D1 is in an open state, and limit switch K1, K2, D2 are closed state.
Referring to shown in Fig. 2, Fig. 3, the Switching Power Supply of portable SA brake switch testers of the invention passes through power switch for cooperation
Connect external AC220V, be converted to after DC24V through Fuse Type switch F1, F2 be connected to first group of a power selection switch it is defeated
Enter end；Lithium battery group is connected to second group of input terminal of the power selection switch through another group of Fuse Type switch.

It corresponds to using external power supply or accumulator come the component for portable SA brake switch testers（Such as each indicator light）It powers and via this
Tester is further to SA equipment out-put supply signals.Tester is connected equipped with power supply indicator with power selection switch, to surveying
Whether examination instrument itself, which obtains power supply, is indicated.
It is also the 24V voltages being converted to through Switching Power Supply in this example, corresponding stir is set on box body panel
Switch, indicator light and positive and negative anodes interface export 24V power supplys outward, it is possible to provide for the solenoid valve of pantagraph current collector external gas source supply.
The Fuse Type switch at F1, F2 Fuse Type switch and lithium battery in the toggle switch corresponding diagram 2 of 24V power supplys at Switching Power Supply；
The closure of the toggle switch or disconnection, to control whether 24V power supplys are linked into follow-up circuit, with the point of 24V power supply indicators
Bright or extinguishing is corresponding to be represented, to reflect that 24V positive and negative anodes interface exports the instruction of 24V power supplys outward.The 24V positive and negative anodes interfaces are outside
24V power supplys are exported, via the tester further to SA equipment out-put supply signals with control action.
The portable SA brake switch testers are additionally provided with four other indicator lights, be respectively used to limit switch K1, K2,
The status display of D2, D1.Wherein, the plug of first cable one end is connected with corresponding connector X0001 sockets, is made and the company
The limit switch K1 of the B/C needles connection of device X0001 is met, is able to be linked into the first finger in tester by the other end of the first cable
Show among the circuit of lamp.When power supply power supply is normal, the limit switch K1's of SA equipment is turned on or off, and should can control first
Indicator light is lighted or is extinguished, if the first indicator light virtual condition really in this way, if limit switch K1 states it is normal；Otherwise the limit
Bit switch K1 failures.
Similar, the plug of second cable one end is connected with corresponding connector X0003 sockets, is made and connector X0003
B/C needles, E/F needles, J/H needles limit switch K2, D2, D1 for connecting respectively, be able to separated by the second cable other end three
Group lead, it is corresponding to be linked into tester second, third, among the circuit of the 4th indicator light.If the limit switch K2 of SA equipment,
D2, D1 respective state that is turned on or off, can correspond to control second, third, the 4th indicator light light or extinguish, then limit
On off state is normal, otherwise breaks down.
The first cable and this one end connected corresponding with connector X0001, X0003 on the second cable have used point in this example
Two plugs opened, and respectively the other end of connecting test instrument is then by sharing the differing needles of same plug, with tester
The signal adapter port connection of box body side（Fig. 1）.Box body opposite side is power adapter port, passes through the power supply with plug
Cable is connect with external power outlet.
As shown in figure 4, in the present invention portable SA testers test method, include below scheme：
S1, check whether the corresponding interface correctly connects：
External air source interface accesses the corresponding input interface of SA equipment；First cable of tester and the connector of SA equipment
X0001 connections；Second cable of tester is connect with the connector X0003 of SA equipment；Connecting test instrument power supply.
S2, the 24V power switches for opening tester；
S3, check whether power supply indicator is normally lighted on tester；If power supply indicator is bright, s4 is continued to execute；If not working,
It returns and performs s1；
S4, check whether indicator light corresponding with limit switch K1, K2, D1, D2 feedback signal is normal on tester；At this time just
Normal state, the lamp for corresponding limit switch D1 is bright, and the lamp of corresponding K1/K2/D2 goes out, if so, continuing to execute s5；If it is not, then
Check respectively for the failure of limit switch D1, K1, K2, D2.
S5, external air source switch startup test is opened；
S6, it checks whether SA equipment acts, whether is stretched out by stream boots：If SA device actions, stretched out, continued to execute by stream boots
Otherwise s7 is returned and is performed s5.
S7, check whether indicator light corresponding with limit switch K1, K2, D1, D2 feedback signal is normal on tester；At this time
Normal condition, the lamp for corresponding limit switch D1 goes out, and the lamp of corresponding K1/K2/D2 is bright, if so, limit switch is normal；If no
It is then to check respectively for the failure of limit switch D1, K1, K2, D2.
According to practical situations difference, in other alternative examples, can by adjusting limit switch with it is corresponding
The mode of indicator light circuit connection, so as to reflect the on/off of limit switch or failure with other forms of expression of each indicator light
State：For example, it is also possible to lighting or extinguish by first, second, third, fourth indicator light, to reflect the limiting of SA equipment
Switch the respective disconnection of K1, K2, D2, D1 or conducting state（Not only correspond to the state that is turned on or off of precedent）；It in another example can
So that the light on and off of the first indicator light reflect that limit switch K1's is open close, while the light on and off of the second to the 4th indicator light is made to carry out phase again
Answer break-make of ground reflection limit switch K2, D2, D1 etc..The present invention is not limited this, does not also repeat one by one.
