The evaluation of walking stability has played an important role in clinical medicine for long time. Nowadays, the related study has developed for more than 200years, however, the most application only can be used in hospital and library. Alongwith the progress of society, and the improvement of peoples living standard andhealth consciousness, people pay more attention to their own health and the quality oflife day by day. So the effective methods of assessing balance are needed.In this study, a walking stability assessment system with a tri-axial accelerometerhas been developed. The core of the device is microcontroller. The design adopts awireless system transmitting the sampled data to computer. It can be used in all thoseapplications, like rehabilitation and sports medicine, where the freedom for subjectsmovement is a constraint for the test. The sample applications are presented in whicha quantitative assessment of stabilization in the healthy people was examined. It isproved that the design is effective to assess peoples walking stability.On account of the character that the vestibular organ which feel the accelerationsignal has play an important role on balance, the tests were designed to acquire theacceleration signal of different movements. Based on the original data analysis, therelation between the acceleration and balance state can be revealed.It was showed that the curve and periodicity of the acceleration signal play animportant part in balance. The factors such as the acceleration signal amplitude,frequency, the distribution of the process step, and the step velocity also can be usedas basis to assess the balance. The success of the system design and preliminaryresults will laid the foundation fr the further clinical application.KEY WORDS ： Accelerometer, Walking stability, ADC ， Wirelesstransmission,人们很早就认识到运动平衡能力的评估在临床医疗中有很重要的意义。到目前为止，相关研究已经进行了 200 年。但目前大部分设备还主要应用于医院或是实验室，无法对日常生活中的平衡能力进行准确的评估。随着社会进步，人们的生活水平和健康意识的不断提高，人们日益关注自身的健康和生活质量，因而迫切的需要一种有效的方法来评估自身的平衡能力。本文开发了一种基于三轴向加速度传感器的人体平衡检测系统，采用三轴向直线加速度传感器获取人体运动信息，以单片机为控制核心，采用无线传输方式将采集到的数据传输到 PC 机上，适于检测处于自由运动情况下的对象，因此可以被广泛的应用于康复医学和运动医学。针对前庭器官感受到的加速度信号对人体平衡有重要影响这一特点入手，设计实验采集不同运动状态下的加速度信号。通过对原始数据进行分析，探讨了加速度与平衡状态的关系。实践证明，加速度信号的曲线以及周期性与运动平衡状态有较明显的关系，可以作为判断平衡能力的依据，加速度信号的幅值、频率分布范围以及运动过程中的步长、步速等则可以作为平衡能力评估的辅助依据。该系统的成功设计及初步的实验结果无疑为进一步的临床应用奠定了基础。关键词： 加速度、平衡测量、型 ADC、无线传输As a rapid developing and an important high technical field these years, Robot, byshowing itself and its development, has totally transformed the traditional industryproduction. The main idea of this article is: enabling operators to directly control the robothands via operating data glove, by using serial port communication technique andsynchronous technology, based on robot hands, data glove and RS-232 serial line.Most traditional robot hand control software control robots movement by sendingcommands to the certain computer by operator, which is very complicated control methodand not intuitional, operators have to be trained aforehand and there is a high requirementfor them. The method discussed here is: operators can ware the data glove, which isconnected to certain computer, to control the robot directly, and a virtual scenario operatingwill generated on the computer. The operation is simple, intuitional, and need no trainingfor operator aforehand, and also, with low requirement for operator, who can easily realizereal-time and accurate control of robot.First, a compare of the advantage and disadvantage of the application of ActiveXComponent and the Windows API Communication Function is conducted in this article,MSComm of the Windows API Communication Function has been chosen for thedeveloping of the robot hand serial port communication software and the control protocolof robot hand in this subject has been designed by the data rules discovered by largeamount of experiments and synthesizing the common rules of communication protocol.Second, there will be an integration of the data glove and the robot controllingsoftware, synthetically using synchronization technique to realize the real-time and accuratecontrol of the robot hand by the data glove.After that, Object Oriented technique has been applied to this paper and to improve the expanding ability of robot control software.Finally, based on the original model developed by the theory discussed above, andwith testing, analyzing and improvement of the original model , the anticipative goal had been reached.Keywords: Object-Oriented Communication Protocol Robot Controlling Software Design机器人是近年来迅速发展的一个重要的高技术领域，机器人的出现及发展，已使传统工业生产的面貌发生了根本的变化。本文研究的主要内容是：以机械手、数据手套和 RS-232 串口线为基础，利用串口通信技术和同步技术，操作者可以直接通过操纵数据手套来控制机械手。传统的机械手控制软件大多采用的是：操作者通过向计算机发送命令来控制机器人的运动，这种控制操作复杂且很不直观，操作者要事先进行培训，对操作者要求较高；而在本课题中采用的形式是：操作者戴上数据手套通过计算机，直接来控制机器人，并且在计算机上有生成的虚拟场景辅助操作，操作简单、直观，操作者事先不需要进行培训，对操作者要求较低，操作者可以很容易的对机器人实时、准确的控制。首先，分析比较ActiveX控件和Windows API通信函数的优势和劣势，选取了ActiveX控件中的MSComm方法开发出了机械手串口通信程序，并通过大量试验设计了基于MINI SERVO Explorer机械手通信协议。其次，把数据手套和机械手程序整合在一起，运用同步技术使数据手套能够实时、准确的控制机械手。接着，把面向对象技术应用到本课题中来，增强了机器人控制软件中的扩增能力。最后，根据上面的理论基础开发出了原型系统，并对原型系统进行测试、分析、改进，达到了预期的目标。关键词：面向对象 通信协议 机器人控制 软件设计Abstract The thesis puts forward a gas detector based on spectral analysis technology and embeddedtechnology, and this gas detector adopts Multi-spot measure technology, which gets over Random erroravailably and advances measuring accuracy.

The intelligent capsule for measurement of colon pressure was taken orally synchronously with colontransportation test before surgery and half year after surgery. Way of surgery: left half colon excision weremade if resident time in left half colon of 80% radiopaque particles was more than 72h or 50% of the totalresidence time or colon spleen song syndrome or longer resident time in left half colon detected by intelli-gent capsule or the amplitude of LAPCs and HAPCs was 50% less than those in right half colon. Righthalf colon excision were made if resident time in right half colon of 80% radiopaque particles was more than72h or 50% of the total resident time or the amplitude of LAPCs and HAPCs was 50% less than those inleft half colon. Subtotal colectomy were made if colon transportation test time was more than 120h or thetotal colon pressure wave decreased obviously detected by the digestive tract pressure measurement or thetime of HPACs was less than 6 times/day. Pancolectomy plus bowel resection of rectal were made if colo transportation test time was more than 168h or duodenocecal transit time was more than 24h or the totalcolon pressure wave decreased obviously detected by the digestive tract pressure measurement or the timeof HPACs was less than 2 times/day. Sixteen patients were treated with traditional celiotomy and 15 pa-tients were treated with laparoscopy.ResultsThe total resident time of intelligent capsule, colonic transittime, cluster wave of HAPCs, the average contact amplitude and the corresponding physiologic ratio of be-fore surgery all differed statistically compared with those half year after surgery. There were no statisticdifference between the number of HAPCs and LAPCs. The colonic transit time were statistically shortenedafter surgery. Compared with the traditional surgery group, the Laparoscopy group showed less incidencerate in postoperative intestinal adhesion and intestinal obstruction as well as better improvement of postop-erative constipation. Three early postoperative patients underwent the pancolectomy operation had severediarrhea.ConclusionThe surgery treating resistant slow transmission constipation was effective. Therewere some instructive meaning of colon pressure wave measurement and colon transportation test for theselection of surgical ways. The pancolectomy operation was expected to become the standard surgerymethod for slow transmission constipation because it has smaller trauma and less postoperative complica-tions compared with the traditional operation.Key wordsSlow transmission constipation; Colon pressure; Colectomy摘要目的探讨智能胶囊结肠压力测定对慢传输便秘术式及疗效的评价作用。方法符合罗马III诊断标准、排除器质性便秘、内科治疗3年以上不缓解、有强力手术意愿的慢传输便秘患者31例,术前及术后半年同步口服智能胶囊结肠压力测定和结肠运输试验。术前检查结果决定手术方式:80%的不透X线颗粒在左半结肠停留超过72 h,或大于总
