Abstract
The utility model discloses an automatic control device for a grain drying machine. The automatic control device comprises a single-chip processing module. The single-chip processing module is connected with a grain moisture sensor, a grain temperature sensor and a three-phase SPWM (sinusoidal pulse width modulation) wave output module, and the three-phase SPWM wave output module is connected with the grain drying machine. The automatic control device for the grain drying machine solves the problem of low automation degree of the grain drying machine in the prior art, moisture and temperature parameters of grains are acquired by a sensor, a single chip controls output of three-phase SPWM waves according to the acquired parameters, automatic control of working frequency of the grain drying machine is realized, and working efficiency of the grain drying machine is improved.
Description
Technical field
The utility model has related to a kind of automaton, especially a kind of grain drier automaton.
Background technology
China is maximum in the world grain-production and country of consumption, but grain drying also relies on traditional natural drying method mostly at present, the mechanization degree of grain drying is very low, the grain of results is also often because can not get dry timely, and cause qualitative change, go rotten etc., caused huge loss, therefore the use of grain drier just becomes very necessary, but existing grain drier is all take manual operation as main, automaticity is lower, cause that the drying machine energy consumption is large, efficient is low, and inconvenient operation.
The utility model content
Technical problem to be solved in the utility model provides a kind of grain drier automaton, can realize intelligent control according to the operating frequency of the moisture in the grain and temperature automation adjustment drying machine, has improved the automaticity of grain drier.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of grain drier automaton, comprise single chip processing module, also be connected with grain moisture sensor, cereal temperature sensor and Three-phase SPWM ripple output module on the described single chip processing module, described Three-phase SPWM ripple output module is connected with grain drier.
Aforesaid grain drier automaton is characterized in that: also be connected with touch screen control module on the described single chip processing module.
Aforesaid grain drier automaton is characterized in that: also be connected with respectively A/D converter between described grain moisture sensor, cereal temperature sensor and the single chip processing module.
The beneficial effects of the utility model are: the moisture and the temperature parameter that gather grain by sensor, single-chip microcomputer is according to the parameter control Three-phase SPWM ripple output that gathers, realization has improved the efficient of grain drier work to the automatic control of grain drier operating frequency.
Description of drawings
Fig. 1 is the module connection diagram of the utility model grain drier automaton.
The specific embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, a kind of grain drier automaton, comprise single chip processing module, also be connected with grain moisture sensor, cereal temperature sensor and Three-phase SPWM ripple output module on the described single chip processing module, described Three-phase SPWM ripple output module is connected with grain drier, also be connected with touch screen control module on the described single chip processing module, also be connected with respectively A/D converter between described grain moisture sensor, cereal temperature sensor and the single chip processing module.
Set a moisture and standard temperature by touch screen control module, then grain moisture sensor, cereal temperature sensor gather respectively moisture and the temperature parameter of grain, the process A/D converter is input in the single-chip microcomputer after converting the analogue value that gathers to digital quantity, and the information that show to gather by touch screen control module, single chip processing module is according to the value of setting and the value of collection, adjust the output pulse of Three-phase SPWM ripple output module, thereby regulate the operating frequency of drying machine, realize control is regulated in the automation of drying machine.
In sum, a kind of grain drier automaton that the utility model provides can be realized intelligent control according to the operating frequency of the moisture in the grain and temperature automation adjustment drying machine, has improved the automaticity of grain drier.
Above demonstration and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is by appending claims and equivalent circle thereof.
