Consumed current measuring system and measuring method

Abstract

The invention discloses a consumed current measuring system and a measuring method. The measuring system comprises a digital measuring device, more than two switches and a control computer, wherein the digital measuring device is connected with more than two devices to be measured in series, the devices to be measured are connected with each other in parallel, and the switches are connected in series correspondingly. The control computer is connected with the digital measuring device and the switches, and switches off the switches one by one, corresponding total current consumption values are respectively obtained from the digital measuring device, and then the control computer works out the consumed current value of each device to be measured according to the corresponding total consumed current value. The invention can measure the consumed current values of a plurality of devices to be measured simultaneously only by using a single digital measuring device so as to save test equipment and space.

Description

technical field [0001] The invention relates to a current consumption measurement system and a measurement method, in particular to a measurement system and a measurement method capable of simultaneously testing the consumption current of more than two devices to be tested at one time. Background technique [0002] refer to figure 1 , figure 1 Shown is a schematic diagram of the conventional current consumption measurement system architecture. The current consumption measurement system of general electronic products mostly uses a power supply 1 and a digital ammeter 2 to measure a device under test 3 (DUT). The power supply 1 provides the power required for the operation of the device under test 3 . When the device under test 3 works normally, the consumed current will be measured and displayed by the digital ammeter 2 . Thus, the engineer can know the current consumption of the device under test 3 when it works normally through the digital ammeter 2 . [0003] in additi...
