Embodiment Construction
[0027] Below in conjunction with accompanying drawing, the present invention is further described:
[0028] A parallel differential data acquisition device, comprising an isolated voltage probe 1, a cable sensor 2, a conditioning module 3, 4 acquisition modules 4, a zero-slot controller 8, a CPCI bus 9, and a power supply module 10; The voltage probe 1 and the current sensor 2 with the isolation transformer enter the conditioning module 3 of the acquisition device. The conditioning module 3 adjusts the voltage or current signal to a reasonable acquisition range through the conditioning circuit and then sends it to the acquisition module 4. The CPCI bus 9 is used as the acquisition module 4 As the data interaction hub with the computer, the zero-slot controller 8 performs resource management and process control of the device, and is directly connected with the conditioning module 3, the collection module 4, and the CPCI bus 9 to control the timing of data conditioning, collectio...
