Digital family is the future of intelligent Community system base unit.
The so-called "digital home" is to provide the internal network based on family covers the entire family of intelligent services, including data communications, home entertainment and information appliance control function.1 Introduction
Digital home design of one of the main content of the communication, including domestic and external communication and family communications between related facilities.
From now on development, external communication, primarily through the Internet, broadband access and communication within the family, the author adopts the more competitive the Bluetooth (Bluetooth) wireless access technology.Traditional digital family uses the PC for overall control, lack of humanity.
The author's ideas under artificial emotion a design outfitted with external sensor Intelligent robot, will this smart robot regarded as family members, through its realization on the control of the digital home.This article is an intelligent robot in digital home healthcare applications to model design, Intelligent Robotics and medical apparatus and control PC using Bluetooth technology of communication.
The entire system of lower-cost, feature a more comprehensive, extended application is very broad, great market potential.2 the overall design of an intelligent robot
2.1 Intelligent robot with multiple sensor system
Robot intelligence most important related area is the robot multisensory system and multiple sensing information integration and fusion, collectively referred to as intelligent systems hardware and software components.
Visual, auditory, tactile and force sensing, external sensor and all joints internal Robot sensor fusion use, allows the robot to complete real-time image transmission, voice recognition, features distinguish, positioning, automatic collision avoidance, target detection and other important features of; to the robot with relevant medical module (CCD, CAMERA, stereo microphone, image capture card, etc.) and private medical sensor parts, plus medical expert system can achieve healthcare and remote medical monitoring function. Intelligent robot with multiple sensor system block diagram shown in Figure 1.2.2 Intelligent robot control system
Robot control system consists of 2 parts: the first is the general use of PC, PC, it completed the robot trajectory planning, sensor fusion control algorithms, Visual processing, human-machine interface and remote handling tasks; the second is lower, generally use more SCM system or DSP as controller of core components, complete motor servo control, feedback process, image processing, voice recognition and communication interfaces, etc.
If you use multiple SCM system as a slave, each processor to complete a single task, through information exchange and mutual coordination complete overall system features, but its obvious signal processing capacity has been lacking.
Because the DSP at processing of the signal, and on this smart robot, often need to signal processing, image processing and speech recognition, so using DSP as intelligent robot control system controller.Control system for DSP (TMS320C54x) as the core part, by the Bluetooth wireless communication, GSM wireless communication (supports GPRS), motor drive, digital compass, sensory function sensor (Visual and auditory, etc.), medical sensors and multi-select a serial communication (RS-232) module and other components, control system block diagram shown in Figure 2.
⑴ system by driving motor and steering motor control robot, turning motor information using digital compass as a feedback of PID control.
⑵ uses Ericsson (Ericsson) company ROK101007-circuit as the Bluetooth wireless communication module, the realization of Intelligent Robotics and communication between PC and the PC and the other based on the Bluetooth module for healthcare communication instrument.
⑶ support GPRS GSM wireless communication module support data, voice, SMS and fax service, use of mobile communication and remote medical monitoring center communications.
⑷ because TMS320C54x only one serial port, Bluetooth module, GSM wireless module, digital compass and visual-auditory sensation function sensor module are adopting RS-232 asynchronous serial communication, you must design a multi-select a serial communication module to convert.
When TMS320C54x requires Bluetooth wireless communications module data strobe through circuit; when TMS320C54x need a sensor module data, turn off the last radio communication module at the gate, gate that sensor module. In this way, each module completes the serial communication with TMS320C54x.3 major healthcare functions
Intelligent robot for digital home healthcare can provide the following services:
⑴ medical monitoring
Through the integrated Bluetooth module medical sensors to family members of the main physiological parameters such as ECG, blood pressure, body temperature, respiration and blood oxygen saturation measurement in real time, through the robot handling system provides local results.
⑵ remote diagnosis and consultation
By robot Visual and auditory sensation, such as the acquisition of video, audio and data combined with various physiological parameter data to the remote medical center, the Medical Center's specialists for remote monitoring, combined with the medical expert systems on health of family members to provide consultation, i.e. looking (video), Wen, (audio), cut (various physiological parameters) of the service.
3.1 robot vision and video signal transmission
Robot acquisition of video signal has 2 kinds of: provide robot vision; to be collected by family members of a static image and dynamic images to remote medical center.
Robot vision is from 3-dimensional environment image to obtain the required information and construct environment object clear and meaningful description.
Vision consists of three processes:>⑴ image acquisition.
Through a vision sensor (stereo images of the CCDCAMERA) 3-dimensional environment image converted to electrical signals.⑵ image processing.
Image to image transformation, such as feature extraction.⑶ image understanding.
In the process of giving environment describes.
