【摘要】：在分析主流接近探測(cè)技術(shù)特點(diǎn)和應(yīng)用現(xiàn)狀的基礎(chǔ)上,提出基于高精度無(wú)線測(cè)距和三維定位的井下裝備接近探測(cè)方法。該方法用對(duì)稱(chēng)雙向到達(dá)時(shí)間無(wú)線測(cè)距方法測(cè)量個(gè)人標(biāo)簽到探測(cè)器的距離,通過(guò)三維最小二乘法計(jì)算個(gè)人標(biāo)簽相對(duì)于移動(dòng)設(shè)備的精確坐標(biāo),最后通過(guò)區(qū)域設(shè)定和判斷得出探測(cè)結(jié)果�，F(xiàn)場(chǎng)試驗(yàn)結(jié)果表明,該方法可以實(shí)現(xiàn)設(shè)備周邊360°無(wú)死角探測(cè),與RSSI方法和磁場(chǎng)區(qū)域標(biāo)識(shí)方法相比,具有定位精度高、響應(yīng)時(shí)間短、配置簡(jiǎn)便等特點(diǎn)。
[Abstract]:Based on the analysis of the characteristics and application status of mainstream approach detection technology, a new approach detection method for underground equipment based on high precision wireless ranging and 3D positioning is proposed.In this method, the distance between the personal label and the detector is measured by using the symmetrical bidirectional time of arrival wireless ranging method, and the precise coordinates of the personal label relative to the mobile device are calculated by the three-dimensional least square method.Finally, the detection results are obtained by setting and judging the region.The field test results show that the method can detect 360 擄dead angle around the equipment. Compared with the RSSI method and the magnetic field identification method, the method has the advantages of high positioning accuracy, short response time and easy configuration.
