Runoff sediment concentration measuring equipment system and measuring method thereof

Abstract

The present invention relates to a runoff sediment content measuring equipment system and its measuring method. The measuring equipment system includes a flow measuring device, a filter weighing device and a muddy water volume measuring device connected in sequence; it also includes a microprocessor, a clock module and A storage module, the clock module and the storage module are electrically connected to the microprocessor respectively; the muddy water volume measuring device is provided with a sensor for measuring the sediment concentration in the muddy water, and the sensor is connected with the microprocessor, so The filter weighing device and the muddy water volume measuring device are respectively connected with the microprocessor. The measurement equipment system of the present invention is for automatic measurement without human intervention in the middle, saving labor costs, long-term local storage and real-time upload of data, and multiple backups; because there is no artificial sampling error, the actual measurement effect is more accurate.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a runoff sediment content measurement equipment system and its measurement method, in particular to an equipment system and its measurement method for systematically measuring different levels and depths of runoff sediment discharged from various handle stations , especially to analyze the content of fine-grained sediment in different depths and layers of runoff sediment. Background technique [0002] According to the survey, the total area of ​​soil erosion in the country is 295 million hectares, accounting for 30.7% of the country's land area. In soil erosion research and soil erosion control, the measurement of sediment content in water flow is of great significance. [0003] At present, the most commonly used method to measure the runoff sediment content is the direct measurement method, such as the drying method, also known as the weighing method, that is, to take a ce...

Problems solved by technology

[0003] At present, the most commonly used method to measure the runoff sediment content is the direct measurement method, such as the drying method, also known as the weighing method, that is, to take a certain amount of sample, measure its original weight and the weight after drying, so as to determine the However, due to the drying method, the sample to be tested needs to be dried, and the drying temperature is generally 105°, and the heating takes about 11 hours. High temperature and long-term heating will cause the organic matter in the soil to be carbonized, and the measured The sand content is relatively small, and the requirements for drying temperature and heating time also make the whole measurement process time-consuming and laborious

This method has a long measurement cycle, cumbersome detection process, high labor intensity, and cannot monitor the dynamic process of water flow well.
