Application of automatic system of hydrologic data collection and transmission in the agricultural irrigation regions are studied in order to realize water resource optimal distribution. Advanced hardware equipment and wire-wireless mixture communication method in the system are introduced, and TC-401 induced-method digital stage sensor is applied, which avoids effect of high sediment concentration of Yellow River water and freezing. The software is modularized, and the relation between water-level and flow is simulated by method of adaptive genetic algorithm, which accelerates calculation and reduces errors. Data can be real-time collected, analyzed, processed and stored by the system, and there aregood operation condition and high measuring accuracy. Therefore management technique of irrigation district is improved, water utilization ratio is increased, and scientific data is provided for scientific management, and furthermore, future developing trend of system is analyzed.
