Multi parameter grain situation

Multi parameter grain situation

The multi parameter grain situation has solved the problems of lack of unified planning, repeated system construction, and serious information silos in the construction of grain storage systems in the past. It is a grain storage video system, business management system, and self-control system

A comprehensive management platform that integrates systems and network information systems. Thus achieving control over the grain depotDigitalization

Monitoring, precise business operations, centralized supervision, and networked services”Waiting for digital management functions.

Multi parameter grain situation is an important component unit of information-based grain depots,It is necessary in the construction of information-based grain depots

An indispensable unit. The effectiveness of multi parameter grain situation operation also determines the success or failure of information technology construction. Multi parameter grain situation system for remote interlocking control and data monitoring of on-site equipment in grain depots,And data collection. Multi parameter grain situation is an execution unit in informationized grain depots,It provides data collection for informationized grain depots.

System Composition

The multi parameter grain situation consists of three parts: on-site instruments, controllers, and upper computer;

The controller is the core of the system, responsible for departmental relationships and collecting on-site instrument data,And analyze and process the data.

The upper computer consists of an engineer station and an operator station,The engineer station mainly modifies multi parameter grain situation data and logical relationship programs,The operator station is mainly used to control the start and stop of on-site equipment, monitor the operation status of on-site equipment, alarm information, real-time trends, and other real-time data. Implemented the main functions of process equipment status display and parameter setting.

The data exchange between the upper computer and the controller is completed through industrial Ethernet. With the increasingly mature development of industrial Ethernet technology,The application of industrial Ethernet as a communication protocol for multi parameter grain situation has also become a mainstream development trend. It has the characteristics of high communication speed, strong anti-interference ability, strong resource sharing ability, great potential for sustainable development, and wide application.

Testing Scope

• Simultaneously detect grain temperature, warehouse temperature, humidity, external temperature, humidity, moisture, pests, gases, etc;

• Grain moisture: Based on the moisture sensor, measure the moisture content of the grains in the warehouse to determine if there are any abnormal conditions such as water accumulation;

• Pest detection: The currently popular method of pest detection isNegative pressure extraction, external detection "refers to using a motor to extract pests from the warehouse to the outside, and then distinguish the types and quantities of pests. Strictly speaking, this approach cannot be called an intelligent detection system. The pest detection referred to here is a detection method using intelligent methods such as photoelectric sensors, image processing technology, infrared spectroscopy, etc;

• Phosphine and oxygen detection: Measuring oxygen concentration is an indirect measurement of nitrogen concentration. Effective phosphine concentration and low oxygen concentration are both necessary guarantees for killing stored grain pests. In the detection system, these two values must be able to be automatically collected and fed back to the computer for viewing and data sharing.

• Controlled device detection: Automatically check whether each sensor is faulty.

Basic functions

• Grain situation detection function: It has the functions of regular inspection and timely detection for the above eight types of data;

• Intelligent analysis function: It has the function of establishing corresponding mathematical models based on the changes in grain situation, automatically analyzing and judging the storage status of grain, identifying abnormal parts and values of grain situation, and predicting the trend of grain situation changes;

• Data storage and detection function: equipped with grain situation data storage, historical data query, and network sharing functions (such as the grain temperature data here can be shared with grain cooling and mechanical ventilation);

• Data display and printing function: equipped with display and printing functions such as grain situation data tables and graphics;

• Alarm function: equipped with manual setting of temperature, humidity, moisture, and hazard

Insect and other over limit alarm function.

• Automatic control function: capable of meeting the requirements of grain storage technology and corresponding

Intelligent analysis results enable timely control of grain storage technology equipment

(For example, when the nitrogen concentration is insufficient, it can automatically replenish nitrogen).
