基于LabVIEW的智能婴儿监控系统的设计

针对新生婴儿需要大量人力实时看护的问题,设计了一套智能婴儿监控系统,对婴儿的生理状况进行监测和报警;系统以STM32F103微控制器为控制核心,利用姿态传感检测、温度检测、湿度传感器、脉搏传感器、无线通信、显示电路等外围功能模块,实现对婴儿体温,尿床,脉搏等数据的实时显示和报警;同时,将数据通过ZigBee网络传输至PC机,利用虚拟仪器软件LabVIEW编写服务端功能程序,状态数据可通过Internet远程访问,有效地对婴儿状况进行远程监测;测试结果表明,该系统参数测量精度在2.1%以内,无线传输效果稳定,达到设计预期要求;该设计为婴幼儿智能护理设备设计打下了良好的基础,具有较强的实用性。

Design of Intelligent Baby Monitor System based on LabVIEW

Aiming at the problem that newborn infants need a lot of manpower for real-time nursing, a set of wireless intelligent baby monitoring system is introduced to monitor and warn the physiological activities of infants in nursing state. The system takes STM32f103 microprocessor as the control core, utilizing posture sensor detection, temperature detection, humidity sensor, pulse sensor, wireless communication, display circuit and other peripheral function modules to realize the real-time display and alarm of infant temperature, bed wetting, pulse and other data. Furthermore, the message is transmitted to PC through ZigBee network, and the server function program is designed by using virtual instrument software LabVIEW. The status data can be accessed remotely through Internet, which can effectively monitor the status of infants with high stability. The experiment results show that the system measurement error of the parameters is less than 2.1% and the wireless transmission is stable. The system has laid a good foundation for the design of infant intelligent nursing equipment, and has effective practicability.
