FTJC-4 Dam, Slope Long-term Monitoring Automatic Monitoring System- Micro-deformation Measurement System
I. System Overview
This system adopts the photoelectric image method, and consists of photoelectric targets, imaging measurement systems, GPRS wireless network transmission systems and data collection and analysis software for the control center. It analyzes the tiny deformation of the measured target through the image formed on the photosensitive device by the photoelectric target fixed on the measured target.
The system can conveniently realize remote monitoring through the GPRS wireless network, and is suitable for long-term monitoring and short-term observation in fields such as unattended outdoor areas and areas where wiring is impossible. It has intelligent functions such as remote monitoring, automatic completion of measurement cycles, real-time evaluation of measurement results, and real-time display of deformation trends. Field data can be collected on any computer that can access the Internet. This product can be applied to railway and highway bridge monitoring, landslide monitoring, dam deformation monitoring, subway monitoring, high-rise building monitoring and other fields, and is an ideal system for automatic monitoring of building deformation.
It can not only measure the tiny deformation of the target, but also measure the vibration of the target at the same time. It can provide the forced vibration frequency, natural frequency and amplitude of the measured target, and obtain parameters such as impact coefficient and power spectrum through spectrum analysis. The specific configuration of the quantity, specifications and models of the system's hardware, software and accessories can be customized according to the actual needs of the project.

III. Instrument Features:
1. This monitoring method can accurately measure the tiny deformation of a target 500 meters away, with higher accuracy than similar equipment.
2. The whole machine is designed with industrial grade, suitable for long-term outdoor monitoring, which cannot be replaced by general total station, theodolite and other measurement methods.
3. This system and instrument can conveniently realize remote monitoring, and you can monitor the on-site data as long as you have access to the Internet. The GPRS wireless network transmission is applied, which is suitable for long-term monitoring and short-term observation in fields such as unattended outdoor areas and areas where wiring is impossible.
4. Software with intelligent functions such as real-time evaluation of measurement results and real-time display of deformation trends can be developed according to customer needs.
