一.引言

超声无损检测是利用超声检测物体在一种无损测量方法。超声在界面会产生反射,传输、波形转换和衍射。超声测量的这些特征使用于超声波通过反馈超声波数据的体现检测到的某些特征对象。作为带有定向好的超声波电波，抓住了对象不损坏,渗透能力、无害的人类身体和材料、高检测灵敏度、传播距离等特点,已广泛应用于工业和高科技产业,持续的科技进步发挥了重要的作用[1-4]

随着微电子技术和信息技术迅速发展,超声波测量仪器正逐渐向智能和小型化的方向发展。为了及时、准确反映所有相关参数变化的条件，超声检测信号需要测量某些设备实时采样频率及转让虚拟示波器的实时显示波图。这样的系统，在采集模块和数据处理模块之间数据传输是必要的。传统的超声波测量系统将会使用更多的电缆传输系统,现场进行布线、维修和更新系统升级已经带来了很多的不便。

计算机网络技术，为代表计算机通讯技术已广泛地应用于各个领域。用许多测量工具,无线通信常被用来发送控制信息和数据的信息,以便避免各种不便的电缆系统。作为计算和通信技术的一个分支,在以Zigbee为基础的无线网络通信等方面具有独特的优势低功耗、低成本、网络容量,网络的灵活性,,这是最适用于数据采集前端运输协议。其范围的应用包括在家自动化,工业数据采集控制、环境监测等等[5-8]。

Abstract-Low-power wireless data acquisition is an important technical means to achieve automation and unmanned surveillanc of ultrasonic measurement systeme.Using wireless communication technology for ultrasonic data transfer, an ultrasonic data transfer method based on Zigbee technology is presented. The entire system hardware circuits and principle are discussed. The system consists of ultrasonic sensor nodes, wireless coordinator node and the terminal nodes. Zigbee protocol is used for the wireless transmission of data between nodes. Ultrasonic sensor nodes distributed in the measurement site and is responsible for collecting ultrasound information. Sensor nodes form self-organized the wireless data transmission network with the centre of coordinator nodes. Terminal nodes obtained the data from ultrasound treatment and transferred to the computer through the serial port and display records. Using Tl's CC2430 chip design,nodes make full use of the performance characteristics of the chip SoC with very few external components. The transmission system has good stability, low power consumption and small size. It can be easily laid to completed or under construction building of the application sites, easy to use and maintain.

I. INTRODUCTION

Ultrasonic nondestructive testing is to use ultrasound to detect objects in a non-destructive measurement method.Ultrasound in the interface will produce reflection,transmission, wave-type conversion and diffraction.

Ultrasound measurement of these features is the use of ultrasound through the feedback ultrasonic data reflect some of the characteristics of detected objects. As the ultrasonic beam with a directional well, the seized objects without damage, penetration ability, harmless to human body and materials, high detection sensitivity, transmission distance and other characteristics, has been widely used in industrial and high-tech industries, for the continuous progress ofscience and technology has played an important role [1-4].

As microelectronics technology and the rapid development of information technology, ultrasonic measuring instruments are gradually intelligence and miniaturization direction. In order to timely and accurately reflect all relevant parameters and variation of conditions,......
