【摘要】：隨著GPS技術在變形監(jiān)測中應用的不斷深入,一些國家和地區(qū)建立了用于變形監(jiān)測的GPS連續(xù)運行參考站網(wǎng)絡或者兼有變形監(jiān)測作用的GPS連續(xù)運行參考站網(wǎng)絡綜合服務系統(tǒng)(CORS-Continuously Operating Reference Stations)�；贑ORS系統(tǒng)進行變形監(jiān)測主要是利用CORS基準站和變形監(jiān)測站的實時數(shù)據(jù),進行靜態(tài)基線解算或者進行單歷元解算變形信息。常規(guī)的監(jiān)測方法需要監(jiān)測人員去監(jiān)測點架設儀器進行觀測或者只能進行靜態(tài)后處理而無法進行實時動態(tài)的監(jiān)測。本文基于以上考慮,設計了基于CORS的實時變形監(jiān)測系統(tǒng),并對其中的關鍵技術進行設計和實現(xiàn),使監(jiān)測人員可在第一時間獲取監(jiān)測對象的GPS監(jiān)測信息�；贑ORS的變形監(jiān)測系統(tǒng)包括基站觀測子系統(tǒng)、數(shù)據(jù)采集子系統(tǒng)、數(shù)據(jù)傳輸子系統(tǒng)、數(shù)據(jù)處理與分析子系統(tǒng)四部分。本文介紹了基準站觀測子系統(tǒng)的建立,研究了利用CORS站進行變形監(jiān)測的靜態(tài)時段解和單歷元實時解兩種模型及相應的算法,重點對數(shù)據(jù)傳輸和數(shù)據(jù)采集進行了研究。為了滿足變形監(jiān)測的靜態(tài)后處理和動態(tài)實時處理兩種需求,本文設計開發(fā)了變形監(jiān)測數(shù)據(jù)的實時傳輸子系統(tǒng)。子系統(tǒng)采用CDMA網(wǎng)絡,使用學校的固定IP,使用無線數(shù)據(jù)終端透明傳輸模式,實現(xiàn)了監(jiān)測點和基準點對數(shù)據(jù)中心的全自動無線實時傳輸。在數(shù)據(jù)傳輸?shù)幕A上開發(fā)了數(shù)據(jù)采集子系統(tǒng),也就是數(shù)據(jù)解碼與編碼子系統(tǒng)。數(shù)據(jù)解碼部分實現(xiàn)了將接收機的原始數(shù)據(jù)轉(zhuǎn)換為ASCII編碼的數(shù)據(jù),然后從中提取并計算所需要的偽距、載波觀測值等數(shù)據(jù)進行單歷元解算。數(shù)據(jù)編碼部分將解碼得到的數(shù)據(jù)編碼成RINEX格式的標準文件格式,用來進行靜態(tài)后處理。基于CORS系統(tǒng)進行變形監(jiān)測提高了變形監(jiān)測的穩(wěn)定性,改善了監(jiān)測數(shù)據(jù)的多樣性和實時性,提高了變形監(jiān)測預警系統(tǒng)的可靠性和安全性。
[Abstract]:With the increasing application of GPS technology in deformation monitoring, some countries and regions have established a network of GPS continuous operation reference stations for deformation monitoring or a Corson-Continuously operating reference stations network service system. Deformation monitoring based on cors system is mainly based on the real-time data of the cors datum station and deformation monitoring station to calculate the static baseline or the deformation information of single epoch. Conventional monitoring methods require monitoring personnel to set up instruments to monitor points for observation or can only carry out static post-processing but can not carry out real-time and dynamic monitoring. Based on the above considerations, the real-time deformation monitoring system based on cors is designed in this paper, and the key technology is designed and implemented, so that the monitoring personnel can obtain GPS monitoring information of the monitoring object in the first time. The deformation monitoring system based on cors includes base station observation subsystem, data acquisition subsystem, data transmission subsystem, data processing and analysis subsystem. This paper introduces the establishment of observation subsystem of reference station, studies two models and corresponding algorithms of static time solution and single epoch real-time solution for deformation monitoring by using cors station, and focuses on data transmission and data acquisition. In order to meet the requirements of static post-processing and dynamic real-time processing of deformation monitoring, a real-time transmission subsystem of deformation monitoring data is designed and developed in this paper. The subsystem adopts CDMA network, uses the fixed IPs of the school, and uses the transparent transmission mode of wireless data terminal to realize the automatic wireless real-time transmission between the monitoring point and the datum point to the data center. On the basis of data transmission, a data acquisition subsystem is developed, that is, data decoding and coding subsystem. In the part of data decoding, the original data of the receiver is converted into ASCII coded data, and then the required pseudo-range, carrier observations and other data are extracted and calculated for single epoch calculation. The data encoding part encodes the decoded data into a standard file format in RINEX format, which is used for static post processing. Deformation monitoring based on cors system improves the stability of deformation monitoring, improves the diversity and real-time of monitoring data, and improves the reliability and security of deformation monitoring and early warning system.
