Air conditioner is tried, major function is divided into two parts:
(1) during system test, often there is revolving speed exception in motor, and reason has Vsp spread of voltage, direct current
Busbar voltage is undesirable etc., because the Vsp voltage provided often has overvoltage crowbar, different motor models has
Different Vsp voltage requirements.And export Vsp voltage motor work when cannot in real time reaction controlling output true electricity
Pressure, makes troubles to debugging.In actual test, when a failure occurs, often because mainboard and motor route be it is non-be isolated, it is electric
The non real-time display of road parameter, thus be difficult to determine failure occur accurate location, i.e., can not quickly determine be mainboard side failure also
It is motor side failure, present invention design can quickly check failure.
(2) motor model and load are different in actual production, and motor tooling provided by the invention can record motor work
Parameter, and shown by patterned mode, so that developer can on the touchscreen be adjusted patterned curve
Editor, then switches to stand-alone mode to debug motor.
Test fixture provided by the invention can work in both modes: one kind is mainboard test pattern, and one kind is independent
Test pattern (i.e. electromechanical testing mode).As shown in figure 3, when mode selection switch 208 has selected the port A (including A1, A2, A3)
When, the operating mode of tooling is mainboard test pattern, when having selected the port B when (including B1, B2, B3), the Working mould of tooling
Formula is independent test mode.
During executing test assignment using test fixture of the invention, when a failure occurs, as shown in figure 3, first
Motor interface 204 is connected to measured motor (not shown), independent test mode is selected.It is logical first after selecting the mode
Cross touch screen setting control motor relevant parameter, including start-up parameter (such as DC bus-bar voltage, 15V voltage and Vsp voltage,
Movement etc. under feedback target revolving speed and specified revolving speed), operating parameter etc..Operation is selected after parameter setting is good, so that working plate
It powers to motor, is shown on screen to the parameters of motor at this time, the service manual of motor can be compareed at this time to judge
Motor whether there is failure, i.e., under given conditions, whether motor is consistent with the parameter operation in handbook.This mode can be quick
Check that motor whether there is failure.Further, if test display motor does not have failure, then master control plate interface 202 is used into wiring
It is connected to master control borad (not shown), meanwhile, it keeps motor interface 204 to be connected on motor, powers to tooling, select mode
It selects switch 208 and selects the port A, into mainboard test pattern.Under mainboard test pattern, master control borad mainly provides three voltages,
That is DC bus-bar voltage, 15V voltage and Vsp voltage, wherein DC bus-bar voltage and 15V voltage divide equally two-way, directly logical all the way
It crosses mode selection switch 208 to be connected with motor interface 204, another way inputs A/ after passing through division module 1 and division module 2 respectively
D conversion module.If the Vsp voltage of master control borad output is supplied directly to motor, the circuit inside motor can produce VSP voltage
It is raw to influence, because being unable to be supplied directly to motor, Vsp voltage can be divided into the Vsp voltage output end of master control borad at this time
Three tunnels directly feed division module 3 all the way；Remaining two-way supplies A/D conversion module all the way after isolation module, supplies all the way
Motor, in this way, after access motor the Vsp voltage before and after isolation module can be acquired respectively, so that tester is known that master control
The Vsp voltage that plate provides and the value plus the Vsp voltage after motor.In addition, the feedback pulse input end interface of master control borad and electricity
The feedback pulse output end interface of machine connects, which exports after optical coupling isolation circuit and give controller MCU.MCU with
Display board connection with touch screen, touch screen settable parameter, including motor feedback pulse period etc..MCU set parameter with
Afterwards, collected parameter is calculated, and the results are shown on screen.The data of display include d-c bus voltage value,
15V voltage value, the Vsp voltage value that mainboard provides, in addition the Vsp voltage value after motor, and the motor being calculated turn in real time
Speed, can be by showing that numerical value judges the reason of failure occurs.
Through the embodiment of the present invention, different test patterns is selected using mode selection switch, and in different tests
The mode for carrying out independent test under mode to different test components, has achieved the purpose that independent test motor or master control borad, by
It is individually tested in motor and master control borad, it is achieved that the technology effect that abort situation is motor or master control borad is accurately positioned
