Multifunctional ventilating system controller for granary

Abstract

The invention relates to a multifunctional ventilating system controller for a granary. According to the technical scheme, the multifunctional ventilating system controller for the granary comprises ashell and a circuit board arranged in the shell, wherein the circuit board is provided with a control circuit, the control circuit comprises a CPU module, an RTC clock management module, an Flash storage module, a multipoint temperature measuring module, a feedback input module, an output control module, an LCD interface module, an RS485 communication module and a power management module, and theCPU module is connected with the RTC clock management module, the Flash storage module, the multipoint temperature measuring module, the feedback input module, the output control module, the LCD interface module, the RS485 communication module and the power management module separately. The multifunctional ventilating system controller for the granary has the advantages that the multifunctional ventilating system controller is integrated and multifunctional, one controller has multipoint temperature measuring, input and output control, parameter detection, remote control, liquid crystal display control and other multiple functions, the size is small, the functions are complete, various modes of output control can be selected, the compatibility is good, and the adaptation is strong.

Description

technical field [0001] The invention relates to a multifunctional ventilation system controller for a granary. Background technique [0002] In order to ensure the quality of grain, it is necessary to control the granary with intelligent ventilation and nitrogen atmosphere control. The mechanical equipment (ventilation windows, vents, circulation fans, centrifugal fans, etc.) of different granaries have different configurations (quantity, parameters), which require both detection and control. View visually. [0003] At present, most of the control system solutions on the market use PLC plus various expansion modules, which have the following deficiencies: [0004] (1) Open-loop control. The current system has no grain temperature data collection function, and cannot automatically control the operating status of the ventilation equipment according to the grain temperature data, and cannot achieve a better grain preservation effect; [0005] (2) Splicing of various modules....

AI Technical Summary

Problems solved by technology

The number of modules is large, the price is expensive, and the functions of some modules are actually used only a small part, resulting in waste of module resources;

[0006] (3) Poor compatibility and poor adaptability. In order to control or connect various field devices, different modules need to be replaced

For example, some of the on-site LCDs are 485 communication, some are TTL control, and the same module cannot be compatible with different interface devices;

[0007] (4) High cost, composed of various modules, the overall cost is very high, and many modules only use a small part of the functions, the waste of functions is serious, the overall volume is too large, and other related costs are also increased
