Lake Sarez Dam Deformation Monitoring System Upgrade Joint Debugging

发布时间2022-06-01   

The Deformation Monitoring System of The Lake Sarez Dam in Tajikistan, developed by Research Center for Ecology and Environment of Central Asia (hereinafter referred to as “RCEECA”) in cooperation with the National Time Service Center, Chinese Academy of Sciences has been successfully completed and put into operation in October 2021. The system employs China’s BeiDou high-precision positioning technology and hierarchical communication strategy to carry out deformation monitoring of Lake Sarez Dam and Usoy Dam in Tajikistan. The first two measuring points have continuously provided the relevant departments of Tajikistan with the deformation data information of millimeter-level displacement.

According to the work schedule and the actual operating conditions of the monitoring system in the last 7 months, the research and development task of the monitoring system upgrading was started, that is, adding 6 measuring points to the existing monitoring system, forming an all-round real-time Beidou monitoring network with the existing 2 measuring points, expanding the monitoring range to improve the stability of the network and the continuity of data acquisition and ensure the long-term stable operation of the system without personnel.

In order to achieve the goal of system upgrade, the RCEECA and the National Time Service Center formed a technical team to carry out a one-month system upgrade test and joint debugging work from the end of April. Key tests were arranged around simulation of long-time power failure, loss and automatic recovery of communication link and automatic restart of equipment at all levels, which effectively solved a number of technical problems that occurred during the joint debugging process, passed the simulation tests of various faults and successfully completed remote monitoring of power supply system, remote monitoring of equipment status, real-time transmission of deformation and displacement data and other technical testing and debugging. At present, the upgraded equipment and software meet the installation requirements, and have been assembled in Urumqi for shipment to Dushanbe, Tajikistan.
