Abstract

The invention relates to a low-power product detection method, comprising the following steps: obtaining a current working state of a low-power product to be detected; sending a control command to a control switch according to the power supply and the current working state; making the control switch control its own conduction state according to the control command; enabling a voltage dividing module to control the resistance between the accessed power supply and the low-power product to be detected according to the conduction state of the control switch for sampling the voltage drop across thevoltage dividing module; calculating the current value of the low-power product to be detected by the voltage drop and the resistance of the voltage dividing module formed by accessing a detection loop formed by the power supply, the control switch, the voltage dividing module, and the low-power product to be detected; and determining whether the low-power product to be detected is qualified under the current working state according to the current value. Therefore, a plurality of low-power products to be detected can be detected simultaneously by the control switch and the voltage dividing module with no need to adjust the power supply, which improves the detection efficiency of the low-power product to be detected, and is simple in operation mode.

Description

technical field [0001] The invention relates to product detection, in particular to a low-power product detection method 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...
