【摘要】：近年來(lái)我國(guó)對(duì)煤礦不斷開(kāi)采，，礦坑不斷變深，邊坡也越來(lái)越突出，其中露天煤礦的事故中很多都是由于邊坡的變形和滑坡造成的。要想保證煤礦的所有生產(chǎn)工作都能在安全有序的環(huán)境下進(jìn)行，對(duì)其進(jìn)行安全有效的監(jiān)控是很必要的。GPS技術(shù)由于具有定位精度高、易于實(shí)現(xiàn)等優(yōu)點(diǎn)，被應(yīng)用于各種監(jiān)測(cè)技術(shù)中。將GPS定位技術(shù)應(yīng)用于邊坡監(jiān)測(cè)工作中，可以獲得很高的監(jiān)測(cè)精度，更易于實(shí)現(xiàn)系統(tǒng)的自動(dòng)化。 本系統(tǒng)利用GPS導(dǎo)航定位信號(hào)為基本的監(jiān)測(cè)數(shù)據(jù)，根據(jù)測(cè)相偽距觀(guān)測(cè)方程利用載波相位差分的原理進(jìn)行定位。采用處理軟件對(duì)其進(jìn)行數(shù)據(jù)解算，提出了利用載波相位求差法來(lái)進(jìn)行周跳的探測(cè)和修復(fù)，利用VTEC模型進(jìn)行電離層誤差的修正，利用Black模型進(jìn)行對(duì)流層誤差的修正等，提出了利用霍夫曼編碼來(lái)進(jìn)行GPS數(shù)據(jù)的壓縮。最后確定安裝在煤礦的各監(jiān)測(cè)站的監(jiān)測(cè)點(diǎn)的位置信息，進(jìn)一步形成整個(gè)煤礦的信息集成平臺(tái)。當(dāng)出現(xiàn)異常數(shù)據(jù)時(shí)，系統(tǒng)能夠自動(dòng)及時(shí)地進(jìn)行報(bào)警。與以往的監(jiān)測(cè)技術(shù)比，該系統(tǒng)自動(dòng)化集成度高，定位精度高，反應(yīng)靈敏，數(shù)據(jù)可靠，可用于長(zhǎng)期空間結(jié)構(gòu)監(jiān)測(cè)和狀態(tài)評(píng)估。
[Abstract]:In recent years, with the continuous exploitation of coal mines in our country, the pit is getting deeper and deeper, and the slope is more and more prominent. Many accidents in open pit coal mine are caused by the deformation of slope and landslide. In order to ensure that all production of coal mines can be carried out in a safe and orderly environment, it is very necessary to carry out safe and effective monitoring and control. GPS technology has been applied in various monitoring technologies because of its high positioning accuracy and easy realization. The application of GPS positioning technology in slope monitoring can obtain high monitoring accuracy, and it is easier to realize the automation of the system. The system uses the GPS navigation and positioning signal as the basic monitoring data, and uses the principle of carrier phase difference to locate according to the pseudo-range observation equation. The method of carrier phase difference is used to detect and repair the cycle slip, the ionospheric error is corrected by VTEC model, and the troposphere error is corrected by Black model. Hoffman coding is used to compress GPS data. Finally, the location information of the monitoring stations installed in the coal mine is determined, and the information integration platform of the whole coal mine is further formed. When abnormal data appear, the system can automatically alarm in time. Compared with the previous monitoring technology, the system has high automation integration, high positioning accuracy, sensitive response, reliable data, and can be used for long-term spatial structure monitoring and state evaluation.
