Operation power detecting method provided in an embodiment of the present invention, can be used in the various household electrics for having and saving certification demand
The operation power detection of device equipment.
Fig. 1 is the schematic diagram provided in an embodiment of the present invention for running power detecting method, as shown in figure 1, mainly including：
Step 110, middle control unit exports the first switch-over control signal to switching switch；
Specifically, it is middle control unit the first switch-over control signal output can be on line operating personnel control manually it is defeated
Go out or automatically control switching after electricity detecting measurement equipment to be checked and running to test seat in the plane and connect.
For automatically switching, triggering can be realized by installing sensor additional.
Its detailed process can be：
The connection status between detection device and city's electrical cables is treated by a detection sensor to be detected, works as detection
When being connected to city's electrical cables of power detection station section to measurement equipment to be checked and completing boot action, generation first enables signal hair
Give middle control unit；Middle control unit enables the switch-over control signal of signal output first, the switching of control switching switch according to first
Connection end is switched to be connected with power meter.Wherein, the end that is fixedly connected of switching switch is connected to measurement equipment to be checked.
Step 120, switching switch is according to the first switch-over control signal, and the switching connection end of control switching switch is when default
Between threshold value Nei Youyu cities electrical cables be connected to switch to and be connected with power meter；
Specifically, in order to ensure measurement equipment not power down in handoff procedure to be checked, the handoff response speed of switching switch is needed
Meet certain requirements, therefore switching switch uses and is switched fast switch.For the application on TV machine testing, switching
The handoff response speed of switch is preferably no more than 0.05 second.
When measurement equipment to be checked, which is switched to, to be connected between power meter, detection device is treated by power meter and powered.
Step 130, when the first detection sensor monitors to be connected between measurement equipment to be checked and power meter, generation measurement
Enabling signal；
Specifically, the first detection sensor is arranged at and connected with power meter, connection end and power meter phase are switched when detecting
Connection, i.e., when measurement equipment to be checked to be detected is connected to power meter, generation measurement enabling signal is sent to power meter.
Step 140, power meter treats detection device according to measurement enabling signal and carries out power detection.
Because measurement equipment to be checked is not offline in handoff procedure, thus can save in this step it is existing required for again
Start shooting the time that could be tested, thus improve testing efficiency, improve the efficiency of production line.
Step 150, power meter will treat detection device and detect that obtained detection data are sent to memory and stored.
Step 160, power meter generation detection completes signal and is sent to middle control unit；
Specifically, after power meter will detect that data are sent to and stored, can also realize measurement equipment to be checked oneself
The dynamic civil power cable power supply that power detection station section is switched back into from the connection with power meter.
Step 170, middle control unit controls the switching connection of switching switch to switching switch the second switch-over control signal of output
End is switched to be connected with city's electrical cables of power detection station section.
Thus, that is, the process of whole service power detection is completed, the measurement equipment to be checked in test seat in the plane completes test
Afterwards, it will be moved to next detection seat in the plane, and there is next measurement equipment to be checked to move on the detection seat in the plane.
