Problems solved by technology
This method has the following disadvantages: ①The drainage time of the pump is short, and the encrypted monitoring method is often difficult to accurately capture the start and stop time of the pump, resulting in large seepage monitoring errors; ②The sending and receiving of monitoring commands requires the use of the communication channel of the dam safety monitoring system , high-frequency encrypted monitoring can easily cause system communication congestion and affect system stability; ③ Excessive use of water level gauges significantly reduces the life of monitoring instruments and increases equipment operation and maintenance costs

The invention relates to the technical field of dam measurement and control, and discloses a dam water-collecting well seepage measurement and control integrated system, which comprises a system module assembly, the system module assembly comprises a floating ball switch, a measurement and control module, a data migration program and upper computer software, the measurement and control module is connected with a digital clock, the measurement and control module is connected with the floating ball switch, and the data migration program is connected with the upper computer software. The data migration program integrates data and then uploads the data to a database of the upper computer software, the upper computer software formulates tasks to the data migration program, and the float switch is composed of an external plastic skin and an internal magnetic floater. Based on the floating ball liquid level sensing technology and the OPC technology, a standard communication interface is constructed between different devices, accurate capture of the starting and stopping time of a water suction pump and the corresponding water level and integrated management of monitoring data are achieved, system action redundancy is fully reduced, information barriers between systems are broken, the seepage state of a dam is accurately mastered, and the system reliability is improved. And important guarantee is provided for dam safety.
Description
technical field [0001] The invention relates to the technical field of dam measurement and control, in particular to an integrated system for dam water collection well seepage measurement and control. Background technique [0002] The dam water collection well is an important building for the collection and storage of dam seepage. The seepage monitoring of the water collection well can effectively grasp the seepage state of the dam and provide an important indicator for judging the stability and safety of the dam. [0003] The seepage rate of the water collection well is the total amount of confluence per unit time, which needs to be calculated from the measured water level and the water storage area of the water collection well. Due to the limited capacity of the water collection well, when there is too much confluence, the pump needs to be driven to discharge the accumulated water in the water collection well. Therefore, the key to monitoring the seepage of the water col...
