Hardware Design And Implementation On Self And Auto Medical Assistant System(SAMAS)

There is a high incidence of a series of cardiovascular and cerebrovascular diseases which are need to be monitored at any time with the aging of the world.The number of hospital patients is growing rapidly every day.The current medical resources are obviously insufficient.The doctor difficult and expensive problems,disputes between doctors and patients are increasingly sharp.Although a number of portable medical or household electronic medical devices have been spawned,but they only have a single detection function,and their detection results all need to be artificially analyed.There is no multi parameter information fusion or comprehensive analysis function,no diagnosis platform.So they can not directly help patients solve problems.In this case,it is necessary to research and design a set of self help SAMAS(Self and Auto Medical Assistant System)medical assistance system which can integrate multiple information,Intelligently diagnose and do treatment,by the detection of human health index with wide coverage,such as body weight,blood pressure,electrocardiogram,blood glucose,body temperature,etc.That can well meet the current needs of the community.The information fusion and intelligent diagnosis functions of the SAMAS system are based on scientific and reasonable hardware system.Therefore,Hardware design and implementation of SAMAS system are particularly important.Due to the requirement of the system function and the flexible use in different scenarios,and the wireless communication transmission is the future development trend.Hardware design of the system needs to adhere to the idea of multi information fusion and wireless communication.The studying and designing ideas of SAMAS system and the main work in this paper are as follows:First of all,scientifically and rationally choice sensors that can accurately and reliably collect data of each index according to the health indicators fuctions of SAMAS system,then design the body height and weight,blood pressure,electrocardiogram,blood glucose and body temperature data acquisition devices used for corresponding indexes detection using appropriate circuit element and signal processing chip according to the characteristics of each sensor and communication interface.Secondly,Select the USR-C322 and USR-BLE100 modules corresponding to the Wi Fi and Bluetooth communication schemes to design wireless transceiver and set up wireless transmission networks used for releasing control instructions and uploading the index measurement data.Again,based on the serial port communication control unit of VS2010,design program for conctrolling hardware of the system.The sensor control command can be released by touching screen,then the sensors start to work and the measured data is uploaded.Multinomial medical data such as height,weight,blood pressure,ECG,blood sugar and body temperature are collected and integrated into the upper computer for intelligent health diagnosis of the intelligent diagnostic algorithm program.Finally,test the multiple data acquisition function of the desiged hardware system,and do a comprehensive test after adding the intelligent algorithm program designed by the other students in the same group The test results satisfy expected performance.
