：考虑VxWorks 的中断在具体实现上的特殊性，提出一个针对多块采集板系统的中断设计方案，把传统的中断服务程序分解为中断

服务程序和中断服务任务，利用信号灯进行同步，通过在中断服务任务中引入用户定义的优先级，增强系统处理多中断时的可靠性和实

时性。-】Considering the specificity in the specific realization of interrupt in the VxWorks, this paper proposes an interrupt treatment design of a

system consisted of multiple data acquisition boards. It divides the traditional Interrupt Service Routine(ISR) into interrupt service routine and

interrupt service task, and makes use of the semaphore to synchronize them. By introducing the priority that users define, the design enhances the

real-time performance and stability of the system.
