Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] see figure 1 , figure 1 It is a schematic structural diagram of an embodiment of the current dynamic detection method of the present invention, and this embodiment includes the following steps:

[0023] S11: at the first time t 1 every second time t 2 Collect the working current i once to obtain a collection value i i .

[0024] S12: Set the first time t 1 All collected values ​​within i i Accumulate to obtain the accumulated value Σi. Among them, Σi=i 1 + i 2 +......+i i +......+i n ,i n is the first time t 1 The last collected value in .

[0025] S13: Obtain the working current i at the first time t 1 The average value Δi within.

[0026] Among them, the average value Δi reflects the operating current i at the first time t 1 within the average condition, improved at the first time t 1 The problem that the accuracy of the jud...

Abstract

The invention discloses a current dynamic detection method and a current dynamic detection device. The current dynamic detection method comprises the steps of: acquiring an operating current every second time within first time to obtain an acquisition value; accumulating all the acquisition values within the first time to obtain an accumulated value; acquiring an average value of the operating current within the first time; and judging whether the average value is greater than a threshold current, judging that the operating current is abnormal if the average value is greater than the threshold current or the average value is less than a minimum rated current, and switching off power supply, otherwise, judging that the operating current is normal and acquiring the operating current continuously. By adopting the current dynamic detection method, the precision of current dynamic detection can be improved, thereby improving normal operation of terminal equipment and reducing damage rate of the terminal equipment.

Description

technical field [0001] The invention relates to the field of current detection, in particular to a current dynamic detection method and device. Background technique [0002] Current is the most basic physical quantity in electricity, and the state of working current in terminal equipment can be intuitively reflected through current dynamic detection. Excessive working current will burn out the electronic components, which will affect the operation of the terminal equipment or even destroy the entire terminal equipment, while too small working current cannot provide enough power to ensure the normal operation of the terminal equipment, so the current dynamic detection is very important for improving the terminal equipment. The normal operation of the equipment and the reduction of the damage rate of the terminal equipment play a vital role. [0003] There is such a problem in the existing current dynamic detection technology: when the data collected by the current dynamic de...
