Linear Reticon Status Collection System of the Low Latitude Meridian Circle

It is important to engage some real time detections for a high accuracy astrometry telescope. From the data of detection, we can know the instrument status and stability. And also we can use detection data to make some corrections to the observed data. The basic knowledge about Reticon, and the software and hardw are system of Real Time Status Detection System of the Low Latitude of Meridian Circle (LLMC)are introduced in this paper.
