Investigation of laser rangefinders with sensor network interface
Journal Title: Технологический аудит и резервы производства - Year 2018, Vol 4, Issue 2
Abstract
<p><em>The object of research is a laser rangefinder with a wireless sensor network interface protocol ZigBee, which in this study is proposed for the function of measuring the distance between objects. The main spheres of application are spheres where reliable information about the location of objects relative to each other is required. To increase the reliability, it is proposed to combine the possibility of measuring the distance between objects of sensor networks and data obtained from a laser rangefinder. These two methods are combined in one device.</em></p><p><em>One of the most problematic places is the error of the measuring equipment. Also, for the objects described above, various obstacles are typical, like mechanical (trees, hills, lowlands), and radio interference.</em></p><p><em>In the course of the research, the method of increasing the accuracy of measuring the distance of wireless sensor networks was used. To do this, they are combined with laser rangefinders, which are part of computerized distance measuring systems built on the basis of a combination of measurement methods of a different nature.</em></p><p><em>Site localization studies were carried out for the average deviation value when ranking in 1 m (20 measurements), as well as on the progressive function of the required number of transactions. To calibrate the measured measurements, a minimum period of two-sided pass was calculated for the average value, when the receivers are in close proximity to one another (0.01 m). This average value on was calculated from each ranking measurements before converting to an immediate distance value.</em></p><p><em>The results confirm an improvement in the efficiency of the ranking by averaging a plurality of samples to an error value of 6.0 m. The accuracy of the method was constant throughout the test propagation range (within a radius of 250 m).</em></p>
