Abstract

The invention provides a power consumption test system and method. The power consumption tester in the power consumption test system is formed by a main control chip, a first digital electronic ammeter and a second digital electronic ammeter, wherein two ends of the sampling resistor of the first digital electronic ammeter and two ends of the sampling resistor of the second digital electronic ammeter are each in parallel connection with two diodes, and the measuring range of the first digital electronic ammeter is greater than the measuring range of the second digital electronic ammeter; the first digital electronic ammeter, the second digital electronic ammeter and the tested electronic device form one series circuit; the main control chip controls on / off of the series circuit; when the series circuit is turned on, the first digital electronic ammeter and the second digital electronic ammeter respectively measures the current value of the tested electronic device in the current state;and the main control chip acquires the first current value of the first digital electronic ammeter and the second current value of the second digital electronic ammeter at the same time. The power consumption test system and method can also measure the current of the tested electronic device in any state, and can avoid the error which is caused when the ammeters are observed by human eyes, thus improving reliability.

Description

technical field [0001] The present invention relates to the technical field of power consumption testing, and more specifically, to a power consumption testing system and method. Background technique [0002] In the production process of electronic equipment, in order to detect whether there are problems with circuit board soldering, electronic components and component connections, the factory needs to test the power consumption of electronic equipment in different states. When the load status of electronic equipment is clear, current is generally used to represent its power consumption, for example, door lock products powered by constant current. [0003] However, since the current of electronic equipment fluctuates continuously within a certain range, the reliability of power consumption determined by observing the ammeter with human eyes is very low. Contents of the invention [0004] In view of this, the present invention provides a power consumption testing system an...
