In order to quickly detect whether the electronic circuit of electric toys is low-power circuit

a low-power point detection device which using S3C2440 as controller core and electronic loader as measurement unit is designed.Resistance of electronic loader is controlled by S3C2440 through serial port

and the parameters such as voltage and current are measured.The detection device has been successfully applied in quality supervision and inspection.The experimental results show that the device has advantages of simple operation

high measuring precision

good reproducibility and generating detecting report automatically.As a result

the low-power point detection device has improved the detection efficiency and detection precision.
