    Abstract:

    Based on remote networking technology, a dynamic irrigation water diversion system was developed. The system consisted of automatic metering sluice clusters installed on the canals and remote diversion control and management system working in dispatching center. Combined with open channel flow measurement principle and sensor technology, the metering function of the gate was designed. The symmetrical bidirectional coupled winding wheel pulling mechanism and hollow honeycomb structure gate panel were utilized, which could improve the movement reliability and the energy efficiency. An ARM-based gate controller and software system were developed to achieve the gate intelligent control and wireless remote communication function. Various working modes of the sluice could meet the different applications needs. A solar power system was devised to solve the outdoor power supply problem of the automatic gate. To implement the remote linkage control of the sluice clusters, remote water diversion control software package was developed. The application and experiment results showed that the gate terminal had good adaptability to outdoor environment and stable work performance. The water level control error was less than 5mm and the gate gap positioning control error was less than 1mm. Under free flow conditions the flow measurement error was less than 4.6%, and under submerged conditions the flow measurement error was less than 8.3%. The remote automatic metering gate could satisfy all kinds of automatic water conveyance project applications.
