Answer-grabbing devices are widely used in various TV programs, competitions and other fields. At present, with the increasing demand for fairness in competition, higher requirements have been put forward for answer-grabbing devices, such as higher sensitivity, better reliability, more powerful functions and so on. To meet this requirement, this paper designs a answer-grabbing devices based on Labview, which consists of answer-grabbing module, display module, compere button module and control module. Through design of front panel and program, debugging and operation, the functions of answer-grabbing device, as timing, scoring and zero clearing are finally realized. Experiments show that the system has high reliability, sensitivity and multiple functions.
