IV. Working Principle

The core working logic of the NI PXI-8186 is "System Initialization → Module Collaboration → Data Acquisition → Processing and Storage → Communication Interaction", with the specific process as follows:

System Initialization: After the controller is powered on, it scans all PXI/PXIe modules in the chassis through the PXI bus, identifies the module models and functions, loads the corresponding drivers, completes system resource allocation (address, interrupt, DMA channel), and initializes the operating system and application software.
Module Collaboration: According to the test program instructions, the controller sends control commands to target modules (e.g., DAQ modules, signal conditioning modules) through the PXI bus, configures module parameters (sampling rate, range, trigger mode), and coordinates the synchronous operation of multiple modules (supporting trigger synchronization and clock synchronization).
Data Acquisition: After the signals from external sensors or signal sources are converted into digital signals by the PXI modules, they are transmitted to the controller memory through the PXI/PCIe bus. The controller realizes high-speed data transmission through DMA (Direct Memory Access) technology, avoiding excessive CPU usage and ensuring real-time performance.
Processing and Storage: The controller uses the high-performance CPU to process the collected data in real time (e.g., filtering, calibration, feature extraction). On the one hand, the processed data is stored in the local SSD hard drive; on the other hand, it is transmitted to the upper computer or cloud platform through Ethernet or wireless communication, and the data curves and test results are displayed in real time on the local monitor.
Communication Interaction: The controller communicates with external peripherals (printers, barcode scanners) through USB, serial port and other interfaces to output test reports; it receives remote control instructions from the upper computer through the network, adjusts test parameters or starts/stops test tasks, realizing full-process automated control.
