Design of an ARM & ZigBee Based Intelligent System for Hospital Lab Sheet Drawing
Preview AbstractA kind of intelligent system is proposed aiming at the safety issue of hospital lab sheet drawing. The main controller is designed on the basis of the S3C6410 embedded controller with AMR11 kernel and in combination with bar code identification technology, and WinCE6.0 OS is customized on the S3C6410 embedded controller. In order to effective manage the bar code data, the SQlite embedded database is transplanted on the WinCE6.0 and a dialog box based sheet drawing program is developed. The ZigBee network is designed with the CC2530 wireless SCM as core. And the secondary development is performed on the basis of TI Company's ZStack protocol stack, with which the control program for box opening motor is designed. By testing, the mean packet loss ratio of the ZigBee network is 0.34%. In order to further ensure the reliability, the respond-type sending mode is adopted. In this mode, the ZigBee network's success rate of sending 10,000 commands is 100% and the effective control distance of the ZigBee network is up to 25m, so this system fully meets the practical using requirements.
