为解决常规兵器试验场使用的XG‐2002型测时仪测时范围小和显示电路复杂等问题，文中提出了多单片机分布式控制方式实现大范围时间间隔测时仪的方案。通过采用主控单片机连接了两片CPLD ，各自独立实现了两路的测时功能。利用两个从单片机分别接收了主单片机的数据，各自独立控制显示模块进行显示，实现了增大测时仪测量范围的技术需求。对设计的测时仪经信号源进行了验证，实验结果表明：时间测量范围不小于20 s ，相对误差不大于1×10－3‰，满足大范围的时间间隔测量需求。

For the problems of small measurement category and complicated display part of XG‐2002 type chronometer used in proving ground for conventional weapons , a program of dual‐channel‐chronometer with multi‐MCU distributed control mode is introduced .The host microcontroller is connected with two pieces of CPLD to achieve dual‐channel‐measuring functionin independently .While two slave microcontroller were used to receive data from the host microcontroller respectively . The technical requirements of the measurement range of chronometer is realized .The designed chronometer is validated by the signal source .The results show that the measurement range of chronometer is greater than 20 seconds with 1 M Hz oscillator ,the relative error is less than 1 × 10-3 ‰ and can meet the needs of a wide range of time interval measurement .
