基于阿兹海默症患者的感应报警器创新设计
Innovative Design of Induction Alarm for Patients Based on Alzheimer Disease
摘要
Abstract
Objective A sensor alarm device based on the bluetooth technology of single chip computer was designed to detect the dynamic condition of patients with Alzheimer's disease. Methods The device was mainly composed of hardware part and software part. The hardware part was divided into power supply circuit, induction circuit and control circuit. Dynamic monitoring was achieved through data collection, wireless transmission, analysis, etc. The YZC-161B half-bridge sensor was used to monitor the patient's action, collect pressure signals continuously. The stable signal was obtained by amplifying, filtering and shaping of the circuits at all levels. The stable pressure signal was converted into electrical signal to STC89C52 single chip microcomputer by using HX711AD chip. After the single chip microcomputer system signal processing, the hc-06 bluetooth was transmitted to the mobile terminal. The software part used C51 programming to connect Microcontrollers with Bluetooth. Android mobile phone application software was written by Android studio. The mobile phone recorded and displayed patients'steps on the screen, when the number of steps reached a preset value the alarm bell. Results After using the induction alarm device, it could realize monitoring the patient's movement, reduce the guardian's workload and lower the possibility of losing the patient. Conclusion The design can detect the exact action of the patient allow the guardian to understand the patient's dynamics accurately, which can prevent the behavior of patients at night to run out in the first place. It meets the clinical needs, which is valuable for spread.关键词
