Design of SCM Timely Exposure of X-ray Machine / 医疗卫生装备

ABSTRACT

Objective To design a system that is many X-ray machines automatic operation,timely exposure to realize the sharing of power supply. Methods A circuit is designed based on the normal hospital conditions and go with proper control algorithm. The fifty-one series SCM were made use of in the hardware circuits,and validated by X-ray machine simulation tests which simplify the X-ray exposure to the process of relay controlling,which software is based on interrupt mechanism. Results The program could effectively control the exposal of many X-ray machines and the priority was indicated by the experiments. Conclusion Under the prerequisite of the system does not affect the exposure parameters of X-ray machine accuracy,the system can realize a number of X-ray machine's power-sharing,at the same time allow only a single X-ray exposure and use of the interrupted source. And it can make exposure many original X-ray machines can become closely related with high security,proper order and high performance,which has prominent benefits on areas with bad power and equipment conditions.
