The intelligent A/D module is based on the CPCI bus. It mainly realizes the data acquisition and processing of the two-way resolver or auto aligner signals, and is used to collect the azimuth angle and pitch angle of the photoelectric instrument. The resolution is up to 20 bits and the precision is up to 5 for the highest, it also has two-way RS422 interface of gyro angle signal data acquisition and processing capability. The module completes data interaction with the host computer and other modules through dual-port RAM and PCI bus. The module needs to work in an environment where the system provides +5V, and can run stably under operating systems such as Vxworks and Windows XP.

Abstract
The intelligent A/D module is based on the CPCI bus. It mainly realizes the data acquisition and processing of the two-way resolver or auto aligner signals, and is used to collect the azimuth angle and pitch angle of the photoelectric instrument. The resolution is up to 20 bits and the precision is up to 5 for the highest, it also has two-way RS422 interface of gyro angle signal data acquisition and processing capability. The module completes data interaction with the host computer and other modules through dual-port RAM and PCI bus. The module needs to work in an environment where the system provides +5V, and can run stably under operating systems such as Vxworks and Windows XP.
