To monitor and secure the large weapon system, a design scheme of an intelligent instrument with wireless transportation based on ARM was put forward. On the microprocessor S3C2410 hardware platform, by design of the data acquisition and conversion circuit by chips of TLP521-4 and TLC2543, the wireless transportation circuit by chip of CLPD-6710 and multi-serial communication circuit by chips of ICL232, the whole hardware platform to monitor Input/Output data, analog data and send collected data to a host computer was established. Moreover, corresponding software such as I/O device driver, AD device driver, block device driver and monitor program under Linux system was realized too. By applying this data acquisition and communication system, a famous performance is got.
