| At present, simple-function and non-intelligent nursing beds are being used in the rehabilitation centers and hospitals.Those disabled persons must be cared by nurses all the time, and make other people much inconvenient.The purpose of this subject is to make the function of Special Daily-life Bed of Disabled Person richer and meet their requirements.Except some basic functions, the other functions are much more intelligent. So it is meaningful to research on master control module in special daily-life bed of disabled person.First main control module is made by modular design.Whole module is developed independently and can be used in all nursing bed.Second it can help disabled persons to achieve many functions,for example bed controling, detection of physiological parameters and entertainment function. At last, it has a remote wireless alarm module based on GPRS. Not only can it alart when disabled persons are in danger or their physiological parameters are abnormal, but also it can be used as a phone.The hardware of master control module is composed of panel computer, CAN bus communication module, remote wireless alarm module based on GPRS and detection module of physiological parameters. Software is designed as following.1. Development of the bed controling interface:it will complete the design of the bed controling interface and the communication between CAN module and the MPU.2. Development of detection of physiological parameters:it will complete the communication between panel computer and detection module of physiological parameters by serial port.3. Development of remote wireless alarm module based on GPRS:it will achieve the function of remote wireless alarm in medical panel computer.4. Development of entertainment module.This subject makes module of physiological parameters and remote wireless alarm module based on GPRS to be applied in medical panel computer. Besides that, the development of entertainment in master control module brings disabled persons nice mood and enjoyment. |
