Research On The Intelligent Shadowless Lamp Control System Based On STM32

With the development of electronic information technology, intelligent automation equipment has penetrated into various traditional industries. Especially highly depends on the personal ability of the medical device industry. Shadowless lamp is necessary for operating room medical equipment, through surgical lighting equipment, in order to implementation and operation of doctors to the best way to observe in the incision and cavity in different depth of objects.Shadowless lamp motion controller performance will directly affect the shadowless lamp spot control precision, sensitivity, but also related to the reliability of the whole system, directly cause great influence on the implementation of the surgeon,even in relation to the patient’s life and health. At present, the traditional shadowless lamp has low control precision, inconvenient adjustment, the problem of the occupation of a large number of operating room space, and modern operating room in the presence of a large number of automation equipment than it appears to be out of tune.In view of the medical electronics market broad scenes and existing application problems and defects, this paper uses STM32 master-slave structure research and development of a high performance embedded multi axis motion of the shadowless lamp controller. The scheme uses STM32 processor as the main controller, the distributed network master-slave control structure. Firstly, around the shadowless lamp controller development, discusses the status quo and the characteristics of the shadowless lamp controller, and controller shadowless lamp at home and abroad research status, summed up the shadowless lamp controller research significance and the research content. Secondly, according to the demand of the system, the shadowless lamp controller of the overall program design, including the overall design of the mechanical structure, the overall design of the hardware circuit, the software architecture of the overall design. Finally, the three elements of shadowless lamp controller is the core control, speed, position and focus control were discussed in details and the design, algorithm considering the real-time and acceleration and deceleration curve of the degree of impact, position precision, the balance between the focusing accuracy by reliable addition and subtraction calculation method, position compensation algorithm, the focus of control algorithm, the realization of the precisecontrol system of position, velocity, and focus.In addition,this paper also on the involved key algorithms is verified by experiments, including the variety of acceleration and deceleration smoothness, impact testing, choose from the most appropriate and deceleration curve; compared with before and after the compensation precision of position control and validate the accuracy reach design requirements; to validate the minimum precision focus map algorithm, shadowless lamp focusing accuracy.Through the above research, the design of motion controller with low cost, high reliability, high integration, upgrade and maintenance is convenient wait for a characteristic, and overcome the shortcomings of the mainstream market shadowless lamp to replace the traditional surgery shadowless lamp.
