Abstract

The invention relates to a granary capacity real-time monitoring system, and belongs to field of grain storage amount monitoring. According to the technical scheme, the granary capacity real-time monitoring system comprises a sensing sub-system, a measuring sub-system, a controlling sub-system and a computing sub-system. The sensing sub-system comprises a pressure sensor, a signal transmission line, a digital voltmeter and a power supplying unit. The measuring sub-system comprises a measuring device, a signal transmission line and a power supplying unit. The controlling sub-system comprises a controlling unit, a switchboard, a communication module and a power supplying unit. The computing sub-system comprises a data receiving unit, a data processing unit and a data displaying unit. The sensing sub-system senses change of grain stack states in real time, the measuring sub-system collects grain face information in a granary, the controlling sub-system controls the sensing sub-system and the measuring sub-system and conducts storage and management on the data collected by the sensing sub-system and the measuring sub-system, and the computing sub-system conducts processing on the storage data of the controlling sub-system and then obtains real-time granary capacity. The granary capacity real-time monitoring system has the advantages of being capable of conducting remote intelligent control, high in measuring precision, high in reliability, good in stability and durability, resistant to dust and corrosion and the like. Furthermore, the granary capacity real-time monitoring system is convenient to popularize and apply.

Description

technical field [0001] The invention relates to a real-time monitoring system for the storage capacity of a granary, in particular to the field of monitoring the quantity of grain stored in a grain bungalow. Background technique [0002] The national grain reserve is an important strategic material that is related to the national economy, the people's livelihood and the national economic security. The competent grain department needs to grasp its quantity in a timely and accurate manner to ensure food security. For this reason, the country has to invest a lot of manpower and material resources every year to clear the warehouse and check the warehouse, which costs a lot of money. (National inspection personnel travel subsidies and inspection handling subsidies are nearly 3 billion yuan each year), and the accuracy and real-time performance of national grain reserve data monitoring cannot be guaranteed. Real-time monitoring system. [0003] Traditional warehouse capacity moni...

Problems solved by technology

Although technicians in the grain industry have conducted research using relevant technical means, there are still many key technologies that have not yet been resolved for the real-time monitoring of grain square warehouse capacity.

First, in terms of grain volume measurement, some people are currently using non-contact monitoring technology to conduct related research, for example: the patent application number 201210224186. The guide rails are arranged in the bungalow, and the three-dimensional laser radar is used to scan and use the high-speed rotating prism to measure the volume. However, this technology does not consider the large amount of dust during the grain entry and exit operations and the toxic gas in the grain fumigation process (H 2 S) corrosion and other dust-proof and anti-corrosion problems will seriously affect the running accuracy of the guide rail or even damage it, and the reliability and stability of the measurement results cannot be guaranteed. High, not suitable for popularization and application in a large number of large granaries; other similar technologies such as ultrasound, image analysis, etc. also have the above problems

Second, the bulk density of grain piles stored in the granary will change with the way of grain in and out, ventilation, fumigation, surrounding environment (with or without vibration), storage time, etc. during the grain storage process, and will have an impact on the final calculation of the warehouse capacity greater impact, but this issue has not yet been resolved
