The invention discloses a flexible integration test method and a flexible integration test system capable of being flexibly configured, which are characterized in that equipment interconnection is realized by adding a network communication interface circuit on hardware, an MAC (Media Access Control) address and a product SN (Serial Number) are programmed in a normal working mode on software, and a tool which is provided by a CPU (Central Processing Unit) manufacturer and can only be used for programming the MAC address and the product SN in a recovery mode is replaced. Circuit parameter testing, software loading, MAC address and product SN programming and functional performance testing are integrated (four-in-one), all tests are completed in one process, meanwhile, through flexible setting of configuration files, the original sub-process testing can be compatible while the quality risk of missing testing is avoided, and the testing efficiency is improved. And when special production requirements ...

D-type power amplifier audio output detection method and device, and medium

Номер: CN116074723A
Автор: HUANG JIACHEN, ZHOU HANZHANG, MA XUEHUAI
Принадлежит:

The invention provides a D-type power amplifier audio output detection method and device and a medium in the technical field of D-type power amplifiers. The method comprises the following steps: step S10, inputting a sine wave signal with a preset frequency into a D-type power amplifier; s20, a filter circuit is connected to the load end of the D-type power amplifier, and the cut-off frequency of the filter circuit is set; step S30, after the sine wave signal is superposed with a carrier signal by the D-type power amplifier, outputting the sine wave signal through a filter circuit; step S40, sampling the output signal of the filter circuit through an ADC and performing fast Fourier transform to obtain a complex sequence corresponding to a sampling point, and further calculating to obtain an effective value of the input signal; and S50, comparing a value obtained by multiplying the sine wave signal by the amplification factor of the D-type power amplifier with a corresponding effective value ...

Принадлежит:

The invention discloses a device for visitor's visit time register of a building intercom system. The method comprises obtaining visitor image information and a light intensity value during visitor's visit through a camera device of an intercom system ladderway machine; and by contrast with a characteristic curve, determining a time period corresponding to the light intensity value during the visitor's visit and performing register, wherein the characteristic curve refers to a characteristic curve of light intensity and corresponding time. The time period is judged and registered through the light intensity value during visitor's visit, and a visiting time register function can be achieved without adding a hardware device.
