Fig. 2 is the schematic diagram provided in an embodiment of the present invention for running power detection device.
Embodiment
Below by drawings and examples, technical scheme is described in further detail.
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.
Further, power meter can will treat detection device and detect that obtained detection data are sent to memory and deposited
Storage.Afterwards, power meter generation detection completes signal and is sent to middle control unit, to realize measurement equipment to be checked it is automatic from power meter
Connection switch back into the civil power cable power supply of power detection station section.
Step 150, the measurement data for the electrical power that processing unit receiving power meter is detected to equipment to be checked, and according to default
Power thresholds scope determines whether measurement data is qualified data;
For different types of measurement equipment to be checked, different power thresholds scopes are had.Therefore can be according to be detected
The type and model of equipment carry out threshold value scope, and are compared to determination measurement data by measurement data and threshold range
Whether it is qualified.
Wherein, when test passes, step 160 and 170 is performed, step 180 is performed if unqualified.
Step 160, when measurement data is qualified data, processing unit exports seat in the plane release signal to middle control unit.
Specifically, by seat in the plane release signal, connection of the disconnection detection equipment on seat in the plane can be controlled, the next stop is moved to
Point.
Its flow specifically performed can be as follows:
After middle control unit receives detection completion signal, to switching switch the second switch-over control signal of output, control is cut
The switching connection end for changing switch switches to and is connected with city's electrical cables.When the second detection sensor detects measurement equipment to be checked again
When being connected to city's electrical cables, generation second enables signal and is sent to middle control unit.Middle control unit is according to seat in the plane release signal and the
Two enable line control signal under signal output.Switching switch disconnects the connection with measurement equipment to be checked according to lower line control signal.From
And detection device disconnects whole connections on seat in the plane, next website can move to.
Step 170, transmission control unit controls the conveyer for transmitting measurement equipment to be checked according to seat in the plane release signal
Detection device is treated to be transmitted.
Specifically, can be transmitted on equipment on-line to be detected by conveyer, it is sent to from a website another
Individual website.After there is seat in the plane release signal, transmission control unit carries out the to be detected of correspondence position according to seat in the plane release signal
Transmission from equipment to next website.
Step 180, when measurement data be number of non-compliances according to when, processing unit to alarm output unit send alarm start letter
Number, by alerting output unit according to alarm enabling signal outputting alarm signal.
Thereby, it is possible to operating personnel on indication wire, equipment detection is abnormal.
