Intelligent gauging meter for open channel and gauging method thereof

Abstract

The invention relates to an intelligent gauging meter for an open channel and a gauging method thereof. The intelligent gauging meter comprises a shell and a circuit board installed in the shell, an antenna electrically connected with the circuit board is installed on the outer part of the shell, a central data processor, a GSM module, a transformer, a power supply module, a flow rate port, a water gate port and a water level port are integrated on the circuit board, and the central data processor is correspondingly connected with the flow rate port, the water gate port and the water level port through an RS232 to 485 module; and the central data processor is further connected with the GSM module and an internet-of-things card. The intelligent gauging meter has the advantages that the flowdoes not need to be considered manually, and a large amount of manpower and material resources are reduced; and a mode of combining wired communication and wireless communication is adopted, the communication is not limited by geographical conditions, data can be collected directly on site, and remote accessing and checking can also be achieved through the internet.

Description

technical field [0001] The invention relates to an intelligent meter for an open channel, belonging to the technical field of water conservancy. Background technique [0002] Water resources are irreplaceable natural resources for human survival and development, and are the lifeblood of agricultural development. Agricultural irrigation water accounts for 70% of the total water consumption in the country. Water delivery monitoring, water saving scheduling and safety management in irrigation areas are related to national food security, flood control and social stability. Research and development of water level measurement and monitoring technology is one of the important means to solve the shortage of water resources in my country, alleviate the contradiction between supply and demand, ensure national water security and realize the modernization of water conservancy. The general flow measurement method is: select a standard section on the channel, erect a flow measurement bri...

AI Technical Summary

Problems solved by technology

[0003] There are certain errors in the calculation results of the existing flow measurement methods, which need to be manually determined, which invisibly increases a lot of workload and wastes a lot of manpower, material and financial resources

The area encirclement method is used to calculate the flow and passing water. The calculation method is complicated, and it is difficult for the grassroots technicians at all levels and section levels to be proficient. The accuracy of the calculation results also needs to be improved, and errors are inevitable.
