In view of this, according to our social medical service development present situation and the practical demand, put forward a kind of multiaxial coordination based robot control techniques and speech recognition technology is muti_function nursing bed concept, successfully developed the robotic nanomanipulation multi-function nursing bed, and on this basis developed based on the nursing bed medical monitoring system of the club. This article mainly discusses the structure of robotic nanomanipulation nursing bed and control system are discussed. Graph one common nursing bed structure 1 robotic nanomanipulation nursing bed structure In the structure of robotic nanomanipulation nursing bed design, the main consideration the following son points: (1) the nursing bed should be able to realize all kinds of the nursing posture pose requirements； (2) all activities of bed panel swing Angle should comply with the medical care for both human comfort； and (3) nursing bed body reliability, stability and safety requirements, should accord with medical care (4) bed body size have certain space limits； (5) to consider nursing bed in the room moving simplicity and medical auxiliary devices (such as hanging liquid frame and book table) in nursing bed f: can be installed sex. The developed machine humanizing nursing bed bed surface structure as shown in figure 1 shows, to realize J, seven basic nursing bed of posture pose demands that a flat, carry back, flexor/leg, SLR, left/right turn, sitting up and solution then, seven panel is independent of each other. Through the coordination between each bed panel, using single movement or movement way to realize nursing bed linkage of all kinds of pose of posture pose. Nursing bed with corresponding bed panel action such as table l.3. Each bed panel swing Angle is as follows: the backplane (posture), o. 10 750； Backplane (left/right emancipated), o. + 65. ； The left/right hip board, O. + 75. ； Thigh board, o. A + 35. ； Crus board, a 55 o + 35. ； Solution will cover and O. A + 90. 2 Robotic nanomanipulation nursing bed of the control system in order to facilitate nursing bed of intelligent control, timely r solution of the current working state nursing bed nursing bed, upon the law to set necessary processes the number of sensors ?. By analyzing the data, sensor transmission control system can real-time understand, control panel of motion, bed of different agencies to prevent the mutual interference or ask to overshoot driven motor bed body, unnecessary casualties caused damage. Control system overall structure as figure2shows. In bed in the control mode pose posture, besides using popular keyboard buttons input methods outside, in order to facilitate the weak and sick, but also increased the speech input mode + operators through the voice commands to manipulate nursing bed. Due to the common types of control chip difficult to complete the voice commands, because the recognition of the nursing bed the control system is divided into two major modules. The first part primarily control module, it consists of a single-chip microcomputer control system structure, used to implement the nursing bed system, including the main control keyboard/voice control commands to accept the position signal and sensor input, and the output motor control signal etc, the second part as auxiliary control module, mainly for voice recognition and playback, it will come from the operators voice control command into electrical signals, then through code conversion, transported to the master control module, and accept the electrical signals to independent control module, will these control instruction convert audio signals of operator can understand. 2.1 robotic nanomanipulation nursing bed master control module master control module at runtime receive signals from the keyboard/speech recognition circuit analysis and processing signal, through, will control signal through external interface conveying to speech playback circuit, signal by voice playback circuit will be transformed into voice signal, provide voice feedback signal, make handlers understand nursing bed real-time dynamic； On the other hand, master control module according to various signal command, control different motor running, so as to realize the lot that users period nursing bed functions? . Master control module mainly include the following each subroutine: (1) keyboard input. The keyboard is nursing bed input control commands by one of the ways the keyboard input, by encoding commands sent to the primary panel by serial. (2) dc motor of the motor control. Nursing bed in accepting the keyboard or speech input signal after, started for the corresponding action to achieve nursing bed. This requires the expected function for installation in the main control panel can the nursing bed eight dc motor both the positive and negative direction of motor control. (3) sensor signal input. Position sensor motor sports location information feedback to control system, control system according to the feedback is returned to the current signal judgment motor sports location and condition, and then calling the corresponding procedure motion control 2.1.1 keyboard control circuit keyboard on the control board for user operation except r equipped with the keys outside, still configuration display the nursing bed the working state of indicator. Considering the keyboard and the communication and the main panel control cPu L / 0 mouths limited resources, so by a separate microcontroller keyboard to treat various task.

Above all appearance conversion between and finish all through eight dc motor FanZhuanLai to realize, so is the main control board must be able to receive commands to eight dc motor after on E reversal, namely can realize motor control negative in nursing bed to electrify control the hardware circuit design, for each motor has adopted two blades double throws on power control. The relay to 2.2 robotic nanomanipulation nursing bed auxiliary control module 2.2.1 speech recognition voice control technology is one of the existing control mode of advanced control mode, it is natural and convenient control mode, good affinity, the characteristics of applicability. Will voice control technology is introduced into the nursing bed under control, will greatly convenient users, particularly in those loss or partly losing activity, ability of self-dependence of patients, voice control and can help them enhance self-confidence, reduce dependence on others, add life courage and confidence in nursing bed users. The characteristics of the speech input commands, used in the study of the beauty of sENsORY company RSc364 little voice chip as recognition core chip. By training and realize Rsc364 chip speech recognition function, system L/o level is TrL level, which can be conveniently and other system for data transmission. Rsc364 chip inside integrated A speech recognition needs A variety of functions, it can complete speech recognition process of anti aliasing low-pass filter, sampling/keep, A/D conversion and voice recording Rsc364 chip in complete functions such as speech recognition task, will voice control signal output to SCM by chip Po and mouth. According to the PSc364 P1, the output state in the Lord with voice recognition chips control by A 74Lsl48 j Duan between expanding in tablet 74Lsl48 fracture, voice command input eight feet of the chip, connect Pl input mouth； Rsc364 Expansion of single chip J Gs meet in P3.2； SCM fracture P1.3 P1. O mouth and speech recognition chips J J 4 Po Po seven connections. When a voice command input, a mouth wipes the P1 output low level, Gs u lose I low-level startup microcontroller external interruption of single chip, the interrupt handlers from P1.0 P1.3 mouth when read people data. Laws 2.2.2 voice playback master control circuit, after receiving orders in control motor running, but also to voice playback son module lose J 【 J voice control signal by auxiliary control module. To the current users provide voice feedback. Speech with the main function modules put the son is: nursing bed receive user commands, in nursing bed function action before the speech information broadcast corresponding action, remind users do physical preparation, this kind of humanized design further improved nursing bed by the affinity of IsD4003_08 chip. Speech playback as the principal chip. IsI) 4003 series work pressure is 3 V, tuen mun recording a single chip 8min for 4 - time?. Chip adopt cMOs technology, containing oscillator, prevent confusion filter, Smoothing filter, audio amplifiers, since the action pixels and high-density multilevel flashing storage arrays, operation orders at through serial communication interface input. 3 robotic nanomanipulation nursing bed nursing bed robotic nanomanipulation control program control mode is a simplified robot control system startup way. After the first test nursing bed, then test each pose, switch state of each key-press test again, if one of the keys pressed nursing bed, then makes the corresponding action and start speech playback program told the operator, through the control speech recognition is like that, if speech recognition module identification, operator a directive, likewise, nursing bed complete corresponding action. 4 closing the robot multiaxial coordinated control technique is applied in nursing bed, may to the robotic nanomanipulation nursing bed. The developed under effective control of the robotic nanomanipulation nursing bed as shown in figure 4 shows, it can achieve more bits of adjustment, and USES the posture voice commands and keyboard input two modes for control, easy and flexible. Moreover, the master control module USES a microcontroller, making the system operation r. flexible reliable, low cost. Currently developed nursing bed has in some hospitals trial, reflect good.
