The embodiment of the invention relates to an operating power detecting device comprising a power meter, a power meter power supply, a change-over switch, a central control unit, a processing unit, and a transmission control unit. The power meter is used for measuring an electric power of to-be-tested equipment; the power meter power supply connected to the power meter provides power for the power meter; a fixed connection terminal of the change-over switch is connected with the to-be-tested equipment and a change-over connection terminal is connected to a commercial power cable or the power meter, and a change-over response speed of the change-over switch is lower than a preset time threshold value; the central control unit connected with the change-over switch outputs a change-over control signal and controls a connection position of the change-over connection terminal of the change-over switch; the processing unit is used for receiving measurement data, from the power meter, of the electric power of the to-be-tested equipment, determining whether the measurement data are qualified ones according to a preset power threshold range, and outputting a position releasing signal when the measurement data are qualified ones; and the transmission control unit controls a transmission device to transmit the to-be-tested equipment based on the position releasing signal.
Description
technical field [0001] The invention relates to the electrical field, in particular to an operating power detection device. Background technique [0002] At present, due to the current energy-saving certification requirements in many countries, and the requirements are becoming more and more stringent, the power margin of the TV is getting smaller and smaller. Therefore, it is necessary to measure the power-on power online to ensure the accuracy of the measured value. The deviation between the power and the actual running power is sufficiently small. [0003] On a normal production line, the 220V wire is connected to all the TVs on the line body at the same time, so it is impossible to measure the power of a single TV. Therefore, when measuring, one TV must be connected to the power meter after it is offline, and then turn on the power. Measurement. [0004] Since it takes time to turn on the TV (more than 10 seconds for functional phones and more than 30 seconds for smart...
