The invention provides a farmland drainage modulus calculation system and method, and relates to the field of farmland drainage. The problem that actually measured farmland waterlogging information is less, resulting in inaccurate drainage modulus estimation in the prior art is solved. The system comprises at least one ZigBee subnet, the subnet ZigBee comprises a plurality of crop waterlogging monitoring terminals distributed in a farmland and used for monitoring the waterlogging information of the farmland in each flood process; a plurality of drainage channel monitoring terminals distributed in a drainage channel and used for monitoring the waterlogging information of the drainage channel in each flood process; the subnet ZigBee summarizes the waterlogging information monitored in the subnet and transmits the waterlogging information to an upper layer network through a gateway; and a management center server connected with the gateway through a wireless communication network and used for receiving the waterlogging information, determining the parameters of a farmland waterlogging confluence module and determining the drainage modulus of the farmland. By adoption of the farmland drainage modulus calculation system and method, comprehensive waterlogging information and accurate drainage modulus can be obtained, and it is conducive to realizing efficient drainage.
Description
technical field [0001] The invention relates to the field of farmland drainage, in particular to a system and method for measuring and calculating a farmland drainage modulus. Background technique [0002] For low-lying areas, when the rainfall or rainfall intensity is large, they are often soaked and submerged by waterlogging due to the untimely drainage, resulting in reduced or no harvest of crops, flooding or suspension of business materials, and flooding of residential buildings. Collapse and life is difficult. For example, the Lixiahe area in Jiangsu Province, the Sanjiang Plain area in Heilongjiang, the Hangjiahu area in Zhejiang Province, and the polders around Dongting Lake in Hunan Province are all well-known waterlogging-prone areas. [0003] Affected by physical and geographical characteristics, terrain and terrain conditions, river systems, lakes, planted crops, distribution of drainage areas, and layout of flood control projects, there are significant differenc...
