Abstract
The invention discloses an automatic control system of a grain drying machine. The automatic control system comprises an ARM (advanced RISC machines) microprocessor control module, wherein the ARM microprocessor control module is connected with a temperature control module, a drying machine heater and a temperature sensor in sequence; the temperature sensor is connected with the ARM microprocessor control module; the ARM microprocessor control module is connected with a humidity control module, a drying machine blower and a humidity sensor in sequence; and the humidity sensor is connected with the ARM microprocessor control module. According to the invention, the automatic control system solves the problem of relatively low automation degree of the grain drying machine in the prior art; the hot wind temperature and the grain humidity in the grain drying process are controlled automatically; and the drying degree of the grain reaches to a predetermined value so as to realize the intelligent precise control.
Description
Technical field
The present invention relates to a kind of crop dryer automatic control system, belonged to the drying machine technical field.
Background technology
Along with China's rural reform of the economic structure deeply with the raising gradually of mechanization of agriculture degree, the application of grain dry machinery and universally will become a kind of inexorable trend.At present, though the development that existing crop dryer equipment has experienced nearly half a century, the product automation degree is lower, and the experience that relies on operating personnel mostly is manually to be controlled to be the master, and this traditional control method is difficult to obtain the better controlling effect.
Summary of the invention
Technical problem to be solved by this invention provides a kind of crop dryer automatic control system; Can carry out automation control to the hot blast temperature in the cereal dry run, cereal humidity; And the aridity that makes cereal reaches predefined value, the intelligent accurately control of realization.
In order to solve the problems of the technologies described above, the technical scheme that the present invention adopted is:
A kind of crop dryer automatic control system; Comprise ARM microprocessor control module; Be connected with temperature control modules, drying machine heater, temperature sensor in turn on the said ARM microprocessor control module, said temperature sensor is connected with ARM microprocessor control module; Be connected with humidity control module, drying machine blower fan, humidity sensor in turn on the said ARM microprocessor control module, said humidity sensor is connected with ARM microprocessor control module.
Aforesaid crop dryer automatic control system is characterized in that: said ARM microprocessor control module also is connected with the keyboard to set up module.
Aforesaid crop dryer automatic control system is characterized in that: said ARM microprocessor control module also is connected with memory module.
Aforesaid crop dryer automatic control system is characterized in that: said ARM microprocessor control module also is connected with watchdog circuit.
Aforesaid crop dryer automatic control system is characterized in that: be connected with the A/D modular converter between said temperature sensor and the ARM microprocessor control module, be connected with the A/D modular converter between said humidity sensor and the ARM microprocessor control module.
The invention has the beneficial effects as follows: the hot blast temperature in the cereal dry run, cereal humidity are carried out automation control through temperature, humidity sensor and control module; And the aridity that makes cereal reaches predefined value; Realize intelligent accurately control, improved the automaticity of drying machine.
Description of drawings
Fig. 1 is that the module of crop dryer automation control system of the present invention connects sketch map.
The specific embodiment
To combine Figure of description below, the present invention will be further described.
As shown in Figure 1; A kind of crop dryer automatic control system; Comprise ARM microprocessor control module, be connected with temperature control modules, drying machine heater, temperature sensor in turn on the said ARM microprocessor control module, said temperature sensor is connected with ARM microprocessor control module; Be connected with humidity control module, drying machine blower fan, humidity sensor in turn on the said ARM microprocessor control module; Said humidity sensor is connected with ARM microprocessor control module; Be connected with the A/D modular converter between said temperature sensor and the ARM microprocessor control module; Be connected with the A/D modular converter between said humidity sensor and the ARM microprocessor control module, said ARM microprocessor control module also is connected with the keyboard to set up module.
Detect the humidity in the cereal through humidity sensor; When detect humidity value during greater than the value through keyboard to set up; The operating frequency of regulating the drying machine blower fan through humidity control module, until detect humidity value equal to set value the time, control drying machine blower fan quits work; Detect the temperature of cereal through temperature sensor; When detect temperature value during greater than the value through keyboard to set up; Regulate the operating frequency of drying machine heater through temperature control modules; Until detect temperature value equal to set value the time, control drying machine heater quits work, and has realized the control to the temperature and humidity in the cereal dry run.
