隨著科學(xué)技術(shù)的發(fā)展，無線技術(shù)在我們生活的不同領(lǐng)域都得到了十分普遍的應(yīng)用，而醫(yī)療方面對無線技術(shù)的需求也是日益增加。 病床呼叫是進(jìn)行醫(yī)患溝通從而傳遞臨床信 息的重要方式 , 病人可通過病房呼叫系統(tǒng)將請求迅速傳遞到醫(yī)生或護(hù)士處 ,同時(shí)會在監(jiān)控中心主機(jī)上留下及時(shí)準(zhǔn)確并且完整的記錄 , 病房呼叫系統(tǒng)是提高醫(yī)院或養(yǎng)老院等設(shè)施的護(hù)理水平的必備設(shè)備之一。 本設(shè)計(jì)是以 AT89C51 單片機(jī)為核心，通過無線信號傳輸技術(shù)來進(jìn)行信息傳遞從而構(gòu)建出的無線呼叫系統(tǒng)。系統(tǒng)通過鍵盤進(jìn)行信號輸入，無線模塊進(jìn)行信號發(fā)送和接受，信號通過單片機(jī)處理進(jìn)而發(fā)送到數(shù)碼管顯示模塊和聲音報(bào)警模塊實(shí)現(xiàn)報(bào)警呼叫功能。本系統(tǒng)優(yōu)點(diǎn)是通過單片機(jī)的優(yōu)良性能大大降低了生產(chǎn)的成本，同時(shí)通過無線技術(shù)提高了應(yīng)用范圍，有著 成本低、效率 高、操作方便等特點(diǎn)。 關(guān)鍵詞：單片機(jī)；病床呼叫；數(shù)字顯示；無線傳輸 II ABSTRACT With the development of science and technology, wireless technology has been widely used in different fields of our life, at the same time the demand for wireless technology is also call for help is an important means to transfer the clinical information of the ward call system, the patient39。s request can be quickly transmitted to the doctor or nurse on duty, and keep accurate and plete records in the duty room of the monitoring center on the host, is one of the necessary equipment to improve the level of nursing and hospital ward. The design is based on AT89C51 microcontroller as the core, through the wireless signal transmission technology to transmit information to construct the wireless call system. The system of signal input through the keyboard module, wireless signal sending and receiving signals, and then sent to the digital tube display module and voice alarm module to achieve the alarm call function through the singlechip processing. This system has the advantages of excellent performance through the microcontroller can greatly reduce the production cost, at the same time through wireless technology to improve the range of applications, has the advantages of low cost, high efficiency, convenient operation.
