The advantages of the Ultrasonic Ranger Finder(URF) are simple hardware, easy to obtain the components and the components are inexpensive. Our researches are to investigate the performances of the single frequency ultrasonic range finder to the best accuracy for high precision measurement. The time of flight ranging algorithm is the typical method for the range measure. But in this TOF method, the specific returned signal must have sufficient amplitude and the pulse shape, otherwise, there will have accuracy errors. We have used the software as well to compensate the errors and to increase to a satisfactory accuracy of measurement.

This paper proposes two new ultrasonic distance measurment methods. The first is the dual-frequency. In order to improve traditional ultrasonic distance measurement, it takes all detectable received waves to estimate the real time-of-flight. In addition, considering the measurement efficiency and accuracy, we develop a changed-frequency exciting signal instead of dual-frequency one. It can do more measurement in a constant time. Simulation results reveal that arrival time analyses of two measurement methods have much better accuracy than traditional measurement. The maximun error in dual-frequency measurement is 4.15um and 3.61um in changed-frequency. The real implementation is based on theoretical analys because the accuracy of two methods have been proved. In real measurement data analysis, we examine the feasibility and discuss the error source. Finally, we develop a measurement system with 4mm error accuracy in the 3m range.

The purpose of this research is to design a short-distance measurement system by ultrasonic sensors. A single ultrasonic transducer is employed to serve concurrently as a transmitter and a receiver. Positions of the barrier are determined by the phase shift between the reflection signal and the source signal. In order to separate the outbound signals from the inbound signals, a resistor is inserted between the signal source and the ultrasonic transducer. This research proposes two different methods, namely “analog method” and “digital method”, to retrieve the reflection signal that is superposed upon the transmitted signal. The analog method is simpler but has its accuracy limited by the precision of the electronic components. The digital method, on the other hand, is more complex but yields more accurate results. The phase curve obtained is also more smooth than that obtained by the analog method. We analyze the measured data taking acoustic field effect into account, and divide the data into four groups according to the distance from the transducer (0∼20mm). Four least-squares line segments are generated to fit these data. The distance is then calculated based on the functions governing the fitted curve. Finally an automatic measurement system is constructed using a PC-oscilloscope which has two 12-bit A/D converse. A graphic user interface is established by Visual Basic. The system will automatically display the distance and direction traveled by the linear stage carrying the barrier.

This paper deals with the research on the optimization of using the dual frequency method of ultrasonic distance measurement system. Following the research of dual frequency method algorithm, this paper implements it on the ultrasonic distance measurement system and performs complete experiments and analysis. The dual frequency method is improved from the traditional measurement method. The measurement error of the traditional method rises with the increase of distance. Dual frequency method uses two ultrasound waves in slightly different frequencies, so we are able to reconstruct the wave front arrival time by utilizing the phase difference. Thus, the flying time of ultrasound is much more accurate. The optimal parameters of dual frequency method are proposed to reach the best result of measurement. By experimental results, the maximum error of traditional measurement is reach to 50.21mm.Dual frequency method with optimal parameters improve to 7.6mm. After transmitting first frequency of ultrasound, it must await 4.652ms to transmit second frequency of ultrasound. This is to avoid energy coupling.

Ultrasonic distance measurement systems are often used to measure or detect object because its structure is simple and low cost. The system have two basic measurement methods, one is time of flight which can detect long range but this method is always affected by the condition of environment, the other uses phase to calculate distance, although this method can improve accuracy of the system, the distance measured will reduce. The thesis proposes a new method that generates two frequency signals and uses power combiner to combine into an envelope signal used in the ultrasonic distance measurement system. When the frequency of envelope signal is low enough, distance can be measured is extended.

This dissertation proposes a time-of-flight (TOF) measurement by employing a piezoelectric and converse piezoelectric produced self-interference ultrasonic wave. When using TOF techniques for ultrasonic temperature and distance measurement, the system error is primarily due to the inertia delay phenomenon of machine vibration. This dissertation proposes a novel driving algorithm for an ultrasonic transmitter. The first study proposes an accurate temperature measurement is derived from the measurement of sound velocity by using an ultrasonic time-of-flight (TOF) technique. The study proposes a novel algorithm which combines both amplitude modulation (AM) and phase modulation (PM) for the TOF measurement. The proposed system can reduce error caused by inertia delay when using the AM and PM envelope square waveform (APESW). The APESW ultrasonic driving waveform causes an envelope zero and phase inversion phenomenon in the relative waveform of the receiver. To accurately achieve a TOF measurement, a phase inversion phenomenon was used to sufficiently identify the measurement pulse in the received waveforms. Additionally, a counter clock technique was combined to compute the phase shifts of the last incomplete cycle for TOF. The presented system can obtain 0.1 % TOF resolution for the period corresponding to the 40 kHz frequency ultrasonic wave. Consequently, with the integration of a humidity compensation algorithm, a highly accurate and high resolution temperature measurement can be achieved using the accurate TOF measurement. Experimental results indicate that the combined standard uncertainty of the temperature measurement is approximately 0.39 ℃. The second study proposes an accurate distance measurement system which has self-temperature-compensation (STC) with the environmental average temperature in space, rather than a single point temperature. The proposed system adopts two identical measurement hardware sets using the APESW ultrasonic driving waveform. The first set measures the sound velocity (the environmental average temperature information is also involved) as the result of the temperature compensation data for the second distance measuring set. Without using a temperature sensor, experimental results indicate that the proposed STC distance measurement system can accurately measure the distance. The experimental standard deviation of the linearity with respect to the distance is found to be 0.21 mm at a range of 50 to 500 mm. Moreover, the proposed system’s temperature uncertainty effect produced a standard deviation of 0.093 mm, while the temperature sensor system’s uncertainty effect produced a standard deviation of 0.68 mm. In addition, the proposed driving algorithm benefits from noise resistance and ease of implementation. The algorithm is simple and can be easily adapted for other micro-processors. The main advantages of this AM and PM envelope square waveform (APESW) system are high resolution measurement, low cost, narrow bandwidth requirement, and ease of implementation.

The main aim of this dissertation is to design a highly accurate ultrasonic distance measurement system. The principle of the ranging system is similar to the operation of using a ruler. At first a coarse measurement is done by time-of-flight (TOF) method, and then a fine measurement by phase shift method is adopted to refine the final result. The sound wave propagation speed in the air depends on the temperature. So, to measure the distance more correctly, it is necessary to revise according to the temperature. Therefore, an accurate temperature measurement system is designed in order to increase the accuracy of the distance measurement for the UDMS. At first, a highly accurate binary frequency shift-keyed (BFSK) ultrasonic distance measurement system (UDMS) for use in isothermal air is described. This system presents an efficient algorithm which combines both the time-of-flight method and the phase-shift method. The proposed method can obtain larger range measurement than the phase-shift method and also get higher accuracy compared with the TOF method. A single-chip microcomputer-based BFSK signal generator and phase detector was designed to record and compute the TOF, two phase shifts and the resulting distance, which were then sent to either an LCD for display or a PC for calibration. Experiments were done in air using BFSK with the frequencies of 40 and 41 kHz. Distance resolution of 0.05% of the wavelength corresponding to the frequency of 40 kHz was obtained. The range accuracy was found to be within ±0.05 mm at a range of over 6000 mm. The main advantages of this UDMS system are high resolution, low cost, narrow bandwidth requirement, and ease of implementation. The second, a method for the temperature measurement system (TMS) using two phase-lock-loops (PLLs) is described. A time-domain temperature sensor can convert the temperature into the duty cycle. The PLL circuit developed to emulate the Vernier caliper to measure the duty cycle is able to eliminate the measuring error and obtain higher resolution without increasing the clock frequency. Then, a single-chip microprocessor is designed to get and compute the duty cycle. Thus, the temperature can be easily computed with the duty cycle, and then sent to a Liquid crystal display (LCD) to display. The experimental results show that the resolution of the duty cycle is 1/65280, and the range of the measured temperature is from –25.5 to 102 ℃ with maximum error ±0.05 ℃ in the TMS. Therefore, the main advantages of this system are high resolution, high accuracy, and low cost.

A high accurate Binary Amplitude-Shift-Keyed (BASK) modulated ultrasonic distance measurement system for use in isothermal air is developed. In this paper, we present a simple but efficient algorithm based upon phase shifts generated by three ultrasonic waves with different frequencies. By the proposed method, we can conduct longer distance measurement than the phase-shift method and get higher accuracy results compared with the time-of-flight (TOF) method. Our microcontroller-based system includes two important parts. One is BASK modulation signal generator and the other is a phase meter by which phase shifts of the three different frequency signals are obtained. Data is sent to PC via RS232 serial ports and then recorded and analyzed with LabVIEW. The main advantages of this distance measurement system are high accuracy in long distance measurement, low cost and easily implemented with cheap and common ultrasound transducers.
