Intelligent ventilation method for digital grain bin

Abstract

An intelligent ventilation method for a digital grain bin is characterized in that according to mechanical ventilation management of the grain bin, a computer grain condition detection system is used for detecting ventilation parameters such as temperature and humidity inside and outside a grain pile, by means of calculation and comparison, the ventilation condition is accurately judged, when the ventilation parameters inside and outside the grain pile meet the ventilation purpose, an intelligent ventilation system is started and automatically opens electric windows of the grain bin, a ventilator is started for mechanical ventilation, the optimal time is seized to ventilate and cool stored grain, low-efficiency or invalid or harmful ventilation is avoided, automatic ventilation time of ventilation equipment can be set on background software, and auxiliary units are automatically started and work within required time.

Description

technical field [0001] The invention relates to the technical field of grain storage, in particular to an intelligent ventilation method for digital grain storage. Background technique [0002] The informatization level of my country's grain industry and food system has always been relatively low, especially the unbalanced development of informatization construction, and the adjustment and reform of the grain system in recent years have made the original information supervision infrastructure no longer suitable for the new situation. Scattered, multiple facilities coexist, interface and exchange are independent, standards are not uniform, and information islands are serious. The "Digital Grain Depot" project is under the background of the implementation of the "Digital Grain" project by the State Grain Administration during the "Twelfth Five-Year Plan" period. The grain depot management platform and digital grain depot system, a special project to realize centralized supervi...

AI Technical Summary

Problems solved by technology

[0003] 1) Grain depot information collection methods are backward, and the degree of data informatization is not high: the existing system has unbalanced development of sampling and collection methods for data such as temperature, humidity, pests, gas, and moisture. Except for temperature and humidity, other data collection is overwhelming. Some still use manual means for on-site collection

At the same time, the management personnel often stay in the paper form or the power list of the business system when viewing the data, and cannot intuitively understand the current grain depot information, and cannot establish a visualized concept

The problem is that the database can be modified, leaving loopholes for false data, and lack of effective supervision

[0004] 2) Grain depot management equipment needs manual control, and the degree of automation of data sensing and collection is not high: At present, many grain depot management methods are still in the era of manpower. Operations, such as entering and exiting warehouses, trucks entering and unloading goods, and driving path management, ventilation equipment, refrigeration equipment, etc., cause a certain lag in the adjustment of grain depot data, and cannot be controlled in a timely manner, which often leads to untimely adjustment and management. food loss

[0005] 3) Each control system of the grain depot is relatively independent and lacks a unified linkage mechanism: at present, the control systems or equipment involved in the management of the grain depot are relatively independent, and the access of various front-end sensors has not formed a unified interface standard and protocol. Unified access and standardized management of devices

Most of the equipment or systems have single functions, and there is a lack of coordination among the various systems, making it impossible to complete complex control tasks

[0006] 4) The equipment standards for grain depots are not uniform, and the construction of digital grain depots is slow: At present, there are a large number of manufacturers involved in the construction of digital grain depots. Only sensor product suppliers face many competitors in the same industry. In order to protect their own intellectual property rights and commercial For the purpose of confidentiality, the manufacturers all formulate the interface standards and communication protocols of the products by themselves, and the construction of the digital grain depot is a complex system integration project, involving many manufacturers in different parts. Big obstacles, delaying the progress of the digital upgrading of grain depots

Its shortcomings are that the monitoring range is small, the communication method is single, and the functions are not comprehensive enough.
