탐색 및 안내 기술 is one of the core technologies of AGV/AMR, which greatly affects the efficiency of machine handling. At present, there are multiple navigation modes of automatic transportation equipment on the market, and how users should choose has become a significant issue. This issue will continue with a brief introduction to various navigation and guidance technologies.
키 기술 of AGV 탐색 안내:
In order to Achieve Autonomous Movement of AGV, it is necessary to identify various environmental information based on multiple sensors, such as road boundaries, ground conditions, obstacles, etc. AGV determines the reachable and unreachable regions in the forward direction through environmental perception, determines the relative position in the environment, and predicts the motion of dynamic obstacles, thereby providing a basis for local path planning을 입력합니다.
According to the degree to which AGVs master environmental information, they can be divided into two types: one is global path planning based on known environmental information, and the other is local path planning based on sensor information. The latter environment is unknown or partially unknown, that is, the size, shape, and position of obstacles must be 획득 through sensors.
공통 AGV 탐색 안내 방법
1. 범위 지정 탐색:
이 탐색 기술 is mainly applied to laser binary scanners to scan and measure the surrounding environment, obtain measurement data, and then combine navigation algorithms to achieve AGV navigation. This navigation sensor is usually implemented using a safety laser scanner with safety functions, as using a safety laser scanner can achieve both safety functions and navigation measurement functions.

2. 윤곽선 탐색:
등고선 탐색 is 현재 the most advanced navigation technology for AGV. This technology utilizes a two-dimensional laser scanner to measure and learn the on-site environment, draw the navigation environment, and then perform measurement learning to correct the map to achieve contour navigation function. Use natural environments (walls, columns, and other fixed objects) for free ranging navigation to update positions based on 환경 측정 결과. 장점 윤곽 탐색 % 3a 아니오 필요 반사경 또는 기타 인공 랜드 마크 % 3b 감소 설치 비용 % 3b 감소 유지 보수 작업 % 3b 레이저 탐색 대안.
3. 하이브리드 탐색:
하이브리드 네비게이션 is a collection of multiple navigation methods that have emerged based on changes in the on-site environment. Due to changes in the on-site environment, some navigation methods are temporarily unable to meet the requirements, and Therefore switch to another navigation method to continue meeting the continuous operation of AGV.
