Pulsed Laser Positioning System Design

With the development of society, science and technology has been progress, there is a growing emphasis on efficiency. Laser ranging positioning system provides an efficient solution for remote target location. As more and more sensor devices used in positioning technology, which makes multi-sensor fusion positioning technology made possible with respect to a single sensor, the multi-sensor target location data to get faster. For some of the harsh geographical environment area, close to the measurement task difficulty is high, the risk factor, in order to obtain location information of the region, the study of this system has become an important technique to solve direction.This paper studies the pulsed laser positioning system, multi-module combined measurement techniques and data fusion method to obtain the coordinates of the target information. Through the button on the LCD screen to select, view information intuitively easy to measure. Data transmission to the host computer via RS232module for processing.This paper studies the multi-sensor fusion target positioning system, multi-module combined measurement techniques and data fusion method to obtain the coordinates of the target information. Through the selection of buttons to show the information on the LCD screen, view information intuitively easy to measure. Data transmission to the host computer via RS232module for processing.This paper first analyzes carried out targeting the principle whereby the division of the various functional subsystems. The system consists of data acquisition subsystem, control and data processing subsystem, the data transmission subsystem and information query and display subsystems. Then the structural design of pulsed laser positioning system. Multi-module combined measurement techniques and data fusion method, apparatus by a pulsed laser ranging module, GPS module, tilt modules and electronic compass module for data collection; complete the multi-sensor data acquisition and integration of computing and data processing by MCU control module; through the key module and display module to complete information inquiries; using this system for data communication with the host computer RS232protocol. Next, the software and hardware design of the system. Circuit design of each module; perform SCM and data communication design of each module; complete the program data fusion algorithm design. Finally, the test system hardware and software to complete the positioning of the object.
