Abstract

The invention relates to a low-power product detecting device comprising a control switch, a voltage dividing module, a voltage sampling module and a controller. The control switch is used for controlling the on / off state of the control switch itself according to a control instruction. The voltage dividing module is used for controlling a resistance value between a power supply and a low-power product to be tested according to the on / off state of the control switch. The voltage sampling module is used for acquiring a voltage drop across the voltage dividing module. The controller is used for calculating the present current value of the low-power product to be tested according to the voltage drop and the resistance value of the voltage dividing module after a detection circuit formed by thepower supply, the control switch, the voltage dividing module, and the low-power product to be tested is turned on. The controller is used for determining whether the low-power product to be tested is qualified under a current operating condition according to the present current value. Therefore, it is possible to simultaneously detect a plurality of low-power products to be tested by the controlswitch and the voltage dividing module without adjusting the power supply, thereby improving the detection efficiency of the low-power products to be tested and achieving a simple operation mode.

Description

technical field [0001] The invention relates to product detection, in particular to a low-power product detection device that does not need to reset the measurement range of a power supply, is simple to operate, and has high efficiency. Background technique [0002] With the development of Internet of Things technology, the demand for wireless communication modules is increasing. Among them, low-power consumption and wide-coverage wireless module products represented by Lora and NB-IOT technologies have been recognized by market demand and have shown explosive growth. How to reduce the production cost of this power consumption product and improve the production efficiency is an urgent problem to be studied and solved. [0003] In the production test of low-power products, it is necessary to ensure the quality of each product, and the current test is a very critical link. Usually test the current at the maximum transmit power and the current in the power-saving standby mode...
