Demand Analysis
In the mountainous areas of the transmission line project construction, the road more through the mountains, rivers and valleys, often to excavate a large number of slopes, the excavation of slopes destroyed the original vegetation cover, resulting in the emergence of a large number of secondary bare ground as well as serious soil erosion phenomenon, resulting in ecological damage, in order to prevent the transmission line slope instability, which brings about huge economic losses, our company has developed the transmission line slope on-line monitoring device, which can monitor the surface displacement of the slope, groundwater level, changes in soil displacement at different depths, rainfall monitoring. The device can monitor the slope surface displacement, slope inclination, groundwater level, soil displacement changes at different depths, rainfall monitoring, which is a good solution to the shortcomings of the current traditional manual testing.
the working principle
Transmission line slope online monitoring device is mainly based on Beidou automated monitoring method for real-time automated monitoring of the monitoring body surface displacement, specifically for the Beidou monitoring point and reference point receiver real-time reception of Beidou signals, and through the data communication network real-time sent to the control center, the control center server Beidou data processing software real-time differential settlement of the three-dimensional coordinates of the monitoring point, data analysis software to obtain the monitoring point real-time three-dimensional coordinates, and data analysis software to obtain the monitoring point real-time three-dimensional coordinates, and the data analysis software to obtain the monitoring point real-time coordinates. The data analysis software obtains the real-time three-dimensional coordinates of each monitoring point and compares them with the initial coordinates to obtain the change amount of the monitoring point, and at the same time, the analysis software alarms according to the pre-set warning value.
Functional characteristics
1、Basic configuration of slope monitoring: main control unit, slope monitoring unit, communication unit, power supply unit, mounting bracket and auxiliary materials;
2、Collect high-precision real-time three-dimensional coordinates, base station observation data, monitoring point observation data, as well as ephemeris, precision ephemeris and other data. Send the encrypted data to the service platform through 4G/5G signals
To be solved, and then use the resources of BeiDou ground-based enhancement network to analyze the data ;)
3、BeiDou receiver function: including all the equipment from data acquisition, centralized transmission, solving and processing, displaying and recording, and safety protection facilities such as lightning and anti-theft, etc., realizing the transmission of monitoring data to the monitoring and control center and displaying them.
The monitoring data can be transmitted to the control center and displayed;
4, monitoring system unattended: someone to look after, automatic operation, annual operation reliability rate of more than 99%, the system can meet the 7 × 24 hours of long-time reliable operation, continuous trouble-free operation time of more than 100,000
hours
5、Data real-time display and analysis of shape variables, intermittent assessment of the health status;
6, the center software automatic solution: short response time can be a few minutes to a few hours, and real-time net leveling, automatic assessment of the monitoring results, and the parameters are completely by the user according to different monitoring requirements
Self-setting
7、Daily channel alarms are diverse: Web, APP release and can be alarmed by short messages, no matter when and where you can grasp the dynamics of the power tower deformation;
8、Real-time monitoring of slope deformation landslide point space displacement, etc.;
9, to provide high-quality dual-frequency Beidou measurement data, real-time access to millimeter-level accuracy of the position data, static accuracy for the horizontal: less than ± 2mm +0.5ppm, vertical: less than ± 4mm +0.5ppm;
Power tower wind load vibration in real-time monitoring accuracy: less than ± 10mm ,Vertical: less than ± 20mm;.
10, automatic generation of reports, the formation of reports of the cycle of the user can design their own, such as a week, etc., some of the necessary output information can also be automatically added or deleted by the user, while according to the need for
Automatically generate weekly and monthly change curves of each point.
11, the system adopts modular design, with standardized, integrated design, in order to facilitate on-site installation and maintenance.
