Description
technical field [0001] The invention relates to the field of electronic technology, in particular to a voltage change rate detection method and device. Background technique [0002] At present, software has begun to play a leading role in many application scenarios. The advantages of software to realize product functions are also obvious, such as lower cost, better portability, and easier product upgrades. The software method of over-the-air upgrade is even more The application field of the software has been extended to infinity. [0003] In the prior art, when detecting a voltage change, a software method is also used to detect the voltage change rate. Although software detection has many advantages, software is a programming language after all, and sometimes it is inevitable that the program will run away and become unstable, which will affect the stability of detection. Contents of the invention [0004] The main purpose of the present invention is to provide a voltag...
