摘　　要：本文指出了子午环光栏自动控制系统研制的必要性，并简要介绍了控制原理．结果表明，该控制部分设计合理大大简便了操作．A control system for diaphragm on the DCMT has been proposed. It is necessary to have a control system on the automatic meridian circle to control the nadir mirror and the two auto-collimation imagines. In this paper,the principle of design for the diaphragm is presented. This system can work in both the modes of connecing with computer and offconnecing with computer.The system has been mounted on the DCMT. It has been shown that the design is reasenable and the operation is very convenient.
