Research On The Anti-collision System Applied In Aeroplane Towed Moving On Ground Based On Ultrasonic Measuring

This paper studies how to avoid collision when the airplanes towed are moving on the ground. With the continuous and rapid development of civil aviation industry, the scale of the airplane team of all great airways is becoming larger and larger, and more and more airplanes are parking on the taxiways. Furthermore, the airplanes need to enter and come out frequently during the examinations in order to maintain safety. In this situation, dangerous approach even collision between the airplane and the airplane,the airplane and fixed buildings on the ground happened, so there is great hidden trouble in security. Once such collision happens, the configuration of the airplane will be destroyed, and it will result in huge economic lose.This text uses single-chip microcontroller as the key part. With the help of ultrasonic, distance measuring can be realized conveniently. The low-power wireless RF transceiver can wirelessly transmit the distance data in short distance. Multipoint wireless communication is realized by frequency division multiaddress and time division multiaddress The data is transmitted to LCD by multipoint wireless communication in the receiving terminal. The form that distance displays in the LCD, flash image gives an warning to the trailer tractor driver.Then the airplane collision can be avoided. In view of the fact that the airplanes avoid collision when the airplanes are moving on the ground,this system implements the multi-spots position distance measure,multipoint wireless communication.System frame is presented in the paper .In this article the hardware and software of the whole system is studied and designed. The software implement of distance measure, the wireless transceiver and LCD display is MCS-51 C language.By the analysis and design, it accomplishes the design of testing circuit template and debugged the software and hardware of testing circuit. The experiment has been carried on to each module andi the whole system. The result fully illuminated the feasibility of the design and deficiencies.
