Description
Technical field
The invention belongs to emu vehicle experimental technique fields, and in particular to a kind of low-voltage circuit inspection of vehicle air conditioner
Survey device.
Background technique
In the test of emu vehicle air-conditioning system, existing test method is a people, vehicle the next man on vehicle, two people
Conducting measurement is carried out according to route of the connection table to air-conditioning system with the use of multimeter, to verify the correctness of vehicle line,
Then its function is tested after system power supply.There are the following problems for this mode: first is that due to the control of vehicle air conditioner,
Feedback line is complicated, and two testing crews are apart from each other, and one onboard, and one under vehicle, causes mutually coordinated cooperation tired
Difficulty, actual tests low efficiency bring certain influence to manufacturing schedule；Second is which cannot air-conditioning system function test it
The preceding function to each control relay is tested, and is searched reason after discovery failure when causing to carry out air-conditioning system function test and is answered
The problems such as miscellaneous, difficult.
Summary of the invention
In order to solve because the mutually coordinated cooperation difficulty of two operators causes test efficiency low existing for existing detection mode,
And cause to look into after breaking down when test because that cannot test each control relay before air-conditioning system function test
The technical problems such as reason difficulty are looked for, the present invention provides a kind of low-voltage circuit detector of vehicle air conditioner.
The technical solution adopted for solving the technical problem of the present invention is as follows:
A kind of low-voltage circuit detector of vehicle air conditioner comprising control unit, more connecting cables and multiple
Connector, every connecting cable include multiple input electric wires and multiple output electric wires, and each connector includes multiple connections
Device contact pin；Control unit includes power supply, multiple control switches and multiple signal lamps, and a control switch and a signal refer to
Show that lamp is one group, the two marker number having the same；Power supply, a control switch, two connector pins, two vehicles connect
Connect device contact pin, a control relay coil of vehicle air conditioner is made up of the input electric wire and output electric wire of connecting cable
One coil control circuit；Power supply, a signal lamp, two connector pins, two coupling for land vehicle contact pins, one with
It controls the corresponding control relay contact of relay coil and constitutes one by the input electric wire and output electric wire of connecting cable
Contact control loop；The number of control switch in each coil control circuit with the signal in corresponding contact control loop
The number of indicator light is identical.
It is applied the beneficial effects of the present invention are: the device has succeeded in the test of EMU air-conditioning system, it is practical to try
With working well.The apparatus structure is simple, and operation is convenient, compact, carries keeping conveniently, durable, trouble shoot side
Just, and the function of each control relay can be tested, meanwhile, not needing can be simple, quick using multimeter
The test to air-conditioning system circuit is completed, labor intensity is reduced, test efficiency is improved, to reduce the practical examination of air-conditioning system
Test the period.
Detailed description of the invention
Fig. 1 is the operation principle schematic diagram of the low-voltage circuit detector of vehicle air conditioner of the present invention.
Specific embodiment
The present invention is described in further details with reference to the accompanying drawing.
As shown in Figure 1, the low-voltage circuit detector of vehicle air conditioner of the present invention includes control unit 1, more connections
Cable 2 and multiple connectors 3, every connecting cable 2 include multiple input electric wires and multiple output electric wires, each connector 3
It include multiple connector pins 6.Control unit 1 includes power supply, multiple control switches 4 and multiple signal lamps 5, a control
Making switch 4 and a signal lamp 5 is one group, the two marker number having the same.Power supply, one control switch 4, two
6, two coupling for land vehicle contact pins 7 of connector pin, vehicle air conditioner a control relay coil 8 pass through connecting cable
2 input electric wire and output electric wire constitutes a coil control circuit.5, two power supply, signal lamp connector pins
6, two coupling for land vehicle contact pin 7, one control relay contacts 9 corresponding with control relay coil 8 pass through connection electricity
The input electric wire and output electric wire of cable 2 constitute a contact control loop.The volume of control switch 4 in each coil control circuit
It is number identical as the number of signal lamp 5 in corresponding contact control loop.
When carrying out vehicle air conditioner test, first each connector 3 connector corresponding with vehicle air conditioner is connected
It connects, then by the control switch 4 on operation control unit 1, powers to vehicle air conditioner line related, pass through the device
Corresponding route is applied on the corresponding control relay of the same circuit on route and air-conditioning system, control relay coil 8
Its corresponding control relay contact 9 is closed after electricity, and therefore, corresponding coil control circuit and contact control loop are connect
Logical, the signal lamp 5 of reference numeral is lit, can be simply and rapidly by the display situation of observation signal indicator light 5
Complete to vehicle air conditioner circuit and control the test of relay.If some signal lamp 5 shows incorrect, can lead to
The number for observing the signal lamp 5 of improper display is crossed, can quickly and accurately determine the fault point of vehicle air conditioner.
