摘 要
 醫院為了提高對病人人性化服務的質量，在病床與護士站之間安裝了定位呼叫系統，當病人需要呼叫護士時，通過定位呼叫器通知護士。但這種方式不能給護士傳遞更多的信息。隨著科技的發展，信息時代的醫院管理已經不再像傳統的模式，而是向智能化，網絡化迅速發展，采用總線網絡的方式成為醫院定位呼叫系統的發展趨勢。
 該系統以STR710控制器為核心（它是基于16/32位ARM7TDMI RISC CPU），采用分布式控制系統。在每個病房設置一個從機，進行本病房呼叫信號的采集、報警、顯示控制及語音播報等功能；在護士室和醫生辦公室設置主機，進行報警、呼叫信息的顯示、播報，并將從機采集來的信號進行分類。主機與從機之間通過CAN總線，完成采集信號的遠傳和處理信息的回饋。主機可以通過RS-232接口與PC機通訊。
 該系統可實現對醫院病房的智能化管理，可實現呼叫、監聽、廣播、求救報警、信息儲存、顯示等功能，為醫院和廣大患者帶來更大的方便。同時具有較好的通用性和靈活性，在今后的“醫療呼叫系統”發展中也能處于不敗之地。

Abstract
 In order to improve the human quality of services to the patient, the hospital installs call positioning system between hospital beds and nurses station, when the patients need to call nurses, the nurses can see the message through targeted pager. However, this method can not give nurses more information. With the development of technology, the hospital management is no longer the traditional model in the information times; it is the trend of development to the intelligent, network-based rapid development of a bus network as the way hospitals call positioning system.
 The distributed control system is based on STR710 controller (which is based on the 16/32 bit ARM7TDMI RISC CPU). A slave controller in each ward for collecting the calling sign, warning, controlling and displaying features and voice broadcast is set up in this system; The host in the rooms of nurses and doctors for giving alarm, calling information displayed, broadcast, and classifies the signals collected from the slave controller is also set up in the system. Through communicating the host and the salve with the CAN bus, it completes the acquisition signals in the Far East and dealing with the feedback information. The host computer can communicate PC with RS-232 interface.
  The system can realize the intelligent management of hospital wards, and it can also realize monitoring, broadcasting, alarming, storing, and demonstrating, and so on, it brings to greater convenience for hospitals and the majority of patients. At the same time, it has good versatility and flexibility .The “medical call system” can be developed in an invincible position in the future.
