摘要
介绍了一种基于SN8P1917单片机的输液无线自动呼叫系统。该系统包括发送终端和接收终端;文中详细地介绍了发送终端的电路原理,同时也简要介绍了接收终端的原理;采用了高精度称重传感器来计量输液的重量,保证了系统的安全可靠;系统数据采用无线传输,安装简单便捷,接收终端具有声光报警,同时通过上位机可以实时查阅相关数据,系统设计优化,运行稳定可靠。
The wireless auto--calling system of transfusion alarm based on SN8P1917 Micro--Controller is presented. This system composes of transmission and receive terminals. We introduce the principle of the transmitting terminal in detail and introduce the principle of the receive terminal in brief. This system used the high--precision sensor to weigh all the things of transfusion, thus the system is safe and relia- ble. The data of alarm is transmitted by wireless signal. The receive terminal will alarm by aeousto--optic. The system data will transmit to PC by RS232. The nurse will read all the data of transfusion by clicking the PC system.
