Novel dam safety monitoring automatic measurement and control device

Abstract

The invention discloses a novel dam safety monitoring automatic measurement and control device, and the device comprises a measurement and control center, a measurement and control station, and an intelligent measurement and control device. The interior of the measurement and control center is provided with an upper computer, and the upper computer is connected with a single-chip microcomputer controller. The single-chip microcomputer controller is connected with a logic level converter, and the logic level converter is connected with a CAN bus controller. The CAN bus controller is connected with a signal isolator, and the signal isolator is connected with a CAN bus transceiver. The CAN bus transceiver is connected with a bus, and the bus is connected with the measurement and control station. The interior of the measurement and control station is provided with a main control module, and the main control module is connected with an RS485 bus. The RS485 bus is connected with the intelligent measurement and control device, and the interior of the intelligent measurement and control device is provided with a channel switching circuit. The channel switching circuit is connected with a stress temperature measurer, a stress measurer, a displacement measurer, a two-dimensional displacement measurer, and a water level measurer. The device provided by the invention is high in automation and intelligentization, can collect and process a signal quickly and accurately, and is worthy of being popularized.

Description

technical field [0001] The invention relates to the technical field of hydraulic engineering measurement and control equipment, in particular to a novel automatic measurement and control device for dam safety monitoring. Background technique [0002] The main backwater structure in a dike hydropower station. Also known as barrage. Its function is to raise the water level of the river and form an upstream regulating reservoir. The height of the dam depends on the topography, geological conditions, submerged range, population migration, the relationship between the upstream and downstream cascade hydropower stations, and kinetic energy indicators. As of 1989, the height of the highest hydropower dam in mainland China was 178 meters, and the highest dam in the world was 325 meters (earth-rock dam). The safety of the dam is extremely important, so the monitoring of the safety of the dam should be strengthened. During and after dam construction, the impact on the surrounding ...
