【摘要】：當(dāng)前，網(wǎng)絡(luò)RTK技術(shù)已成為測(cè)繪領(lǐng)域的研究熱點(diǎn)之一。但，該技術(shù)在我國(guó)工程建設(shè)領(lǐng)域尚未普及。并且，幾乎很少對(duì)網(wǎng)絡(luò)RTK的技術(shù)構(gòu)建和應(yīng)用方面進(jìn)行系統(tǒng)地分析對(duì)比。故而本文認(rèn)為有必要對(duì)其進(jìn)行研究。 文章在介紹網(wǎng)絡(luò)RTK技術(shù)原理的基礎(chǔ)上，主要對(duì)單基站網(wǎng)絡(luò)RTK、移動(dòng)基站式網(wǎng)絡(luò)RTK和多基站網(wǎng)絡(luò)RTK的基準(zhǔn)站建設(shè)和技術(shù)構(gòu)建流程做了詳細(xì)的研究，并對(duì)比分析各自的優(yōu)缺點(diǎn)，總結(jié)出對(duì)工程建設(shè)具有參考價(jià)值的建議。 最后，通過(guò)具體實(shí)驗(yàn)研究了坐標(biāo)轉(zhuǎn)換參數(shù)對(duì)測(cè)量精度的影響，，包括已知點(diǎn)含有微小誤差對(duì)測(cè)量精度的影響、控制網(wǎng)的大小不同對(duì)測(cè)量精度的影響兩部分內(nèi)容。然后，又比較分析了三種形式的網(wǎng)絡(luò)RTK測(cè)量精度與距基準(zhǔn)站距離的關(guān)系，在10km、20km、35km范圍內(nèi)對(duì)所選的測(cè)試點(diǎn)進(jìn)行實(shí)時(shí)動(dòng)態(tài)測(cè)量，并對(duì)測(cè)試數(shù)據(jù)的測(cè)量精度進(jìn)行分析比較。得出三種形式的網(wǎng)絡(luò)RTK在什么樣的范圍內(nèi)保證5cm的測(cè)量精度。提出具有一定實(shí)際應(yīng)用價(jià)值的建議。
[Abstract]:At present, network RTK technology has become one of the research hotspots in the field of surveying and mapping. However, the technology has not been popularized in the field of engineering construction in China. Moreover, few systematic analysis and comparison are made on the technical construction and application of network RTK. Therefore, it is necessary to study it in this paper. On the basis of introducing the technical principle of network RTK, this paper makes a detailed study on the base station construction and technical construction flow of single base station network, mobile base station network RTK and multi-base station network RTK, and compares and analyzes their advantages and disadvantages. The suggestions of reference value for engineering construction are summarized. Finally, the influence of coordinate conversion parameters on measurement accuracy is studied through experiments, including the influence of small errors in known points on measurement accuracy, and the influence of different control network size on measurement accuracy. Then, the relationship between the measurement accuracy of three kinds of network RTK and the distance from the reference station is compared and analyzed. The real-time dynamic measurement of the selected test points is carried out in the range of 10 km / 20 km2 / 35km, and the measurement accuracy of the test data is analyzed and compared. The range of three types of network RTK to ensure the measurement accuracy of 5cm is obtained. Some suggestions with practical application value are put forward.
