Description

Technical Field

[0001] This utility model relates to the field of dam safety monitoring and automated data acquisition training technology, and in particular to a mobile dam safety monitoring instrument automated data acquisition training device. Background Technology

[0002] The dam safety monitoring instrument automation system consists of field monitoring equipment, field data acquisition equipment, a communication network, and a monitoring management station. The monitoring instruments at the field stations connect to terminal blocks via cold-pressed terminals, and the terminal blocks are connected to the acquisition modules of the automation system using a socket-type connection. The acquisition modules at the field monitoring stations collect monitoring data on dam settlement, tilt, seepage pressure and flow, underground cavern rock deformation, anchor bolt stress, anchor cable anchoring force, and joint deformation. This data is then converted and transmitted to the automated safety monitoring system located at the management station via control modules, switches, and optical fibers. Within the automated safety monitoring system, the results are automatically calculated based on pre-set formulas and various parameters, generating monitoring result curves and issuing early warnings for abnormal monitoring data.

[0003] Currently, if training and demonstrations are needed on the working principles and methods of automated data acquisition and transmission of dam safety monitoring instruments, it is necessary to bring a laptop equipped with the automated system software to the on-site monitoring station. This training method is greatly affected by factors such as time, road conditions, weather, and on-site management. Because the monitoring instruments are all installed and buried inside the rock (concrete), the on-site monitoring station cannot see the appearance of various monitoring instruments.
