See also Fig. 3, be the flow chart of compound fertilizer production control method of the present invention, it may further comprise the steps:
After the beginning, at first be that this step can be divided into two kinds of situation through operation screen 1 input demand data: first kind of situation is input crop species (step 301), imports planting area or soil data (step 303) afterwards; Second kind of situation is input fertilizer type (step 302), imports data (step 304) such as nitrogen N, phosphorus P, potassium K, organic A afterwards.In other embodiments, the order of step 301 and step 303 can be exchanged or synthesized a step and carry out; Also can import other demand data, as long as computing unit can go out the Compound Mixed Fertilizer Formula of required preparation according to these data computation.
Step after the input demand data is to confirm prescription; This step comprises following detailed step: at first be that recipe calculation unit 23 is according to demand data; Call the data computation Compound Mixed Fertilizer Formula (step 305) in crops characteristic memory cell 21 and the soil data storage cell 22, formulation analysis unit 24 is analyzed prescription and whether is had mistake (step 306), and analyzes prescription whether feasible (step 308); If judged result is that prescription is infeasible, then carry out step 307 back process ends; If judged result is that prescription is feasible, then stores and show suitable prescription (step 309).
Confirm that the step after the prescription is the fertile preparation steps of compound, this step comprises the feasibility analysis step again, the step that connects material, raw material stirring step and other subsequent steps.Below will specify these steps:
At first be the feasibility analysis step: after finishing step 309, then require the operator to select whether to produce (step 311), if the operator thinks that prescription is improper by prescription; Can select not; Program promptly changes over to and withdraws from or wait for (step 310), if the operator thinks that prescription is suitable, hopes to prepare by this prescription; Then select to be, and input production quantity (step 312).Select then whether to start shooting (step 314),, select " denying " back to get into step 313 if do not hope to produce at once; If select " being ", produce instruction feasibility analysis unit 26 and promptly prescription and production quantity are carried out feasibility analysis (step 315), and judge whether feasible (step 316) according to analysis result; If the result who judges is " denying "; Then get into step 317,, then get into the step that connects material if judged result is " being ".
Step connects material: at first be Charge Mixture Control unit 27 distributes creation datas (step 318), and weighing hopper mobile control unit 28 movable metering bucket 71 (step 319) at first then, and judge whether weighing hopper 71 moves to assigned address (step 320); If judged result is " denying ", then return step 319, if judged result is " being "; Then begin blanking and statistics (step 321); Whether the weight of judging blanking arrives setting value (step 322), and said setting value is meant according to the various raw material requirements of filling a prescription and production quantity calculates, if judged result is " denying "; Then continue blanking or compensate (step 323) automatically, return step 321 then; If judged result is " being ", judge that then whether blanking surpasses setting value (step 324), if judged result is " denying ", then gets into step 326; If the judged result of step 324 is " being "; Then stop blanking and report to the police (step 325); Select to report to the police by the operator then and confirm or releasing (step 327),, then get into step 326 if the operator selects alarm release; Confirm if the operator selects to report to the police, then continue to keep stopping and alarm condition of step 325.Step 326 is to judge whether rearmost position, weighing hopper 71 positions; Promptly judge whether to have connect all needed raw materials or weighing hopper reaches setting value; If judged result is " denying ", then return step 319, if judged result is " being "; Then batching is accomplished (step 328), gets into the raw material stirring step.
Raw material stirring step: at first the raw material in the weighing hopper 71 is transferred to elevator bucket (step 329); By elevator bucket raw material is sent in the mixer 73 afterwards; And mix (step 330) by stirring packing control unit 73 pairs of raw materials of 29 control stirring motors; And carry out discharging packing (step 332), can carry out other subsequent steps as required then.When carry out step 330; Also to carry out step 331, promptly judge by creation data statistic unit 210 whether the gained raw material enough accomplishes output, if judged result is " being "; Then carry out other subsequent steps; If judged result is " denying ", then need return step 318, proceed the step that connects material.
Other subsequent steps: when the judged result of step 331 is " being "; Creation data memory cell 211 is carried out creation data storage (step 333); Creation data delivery unit 212 carries out creation data transmission (step 334) through telecommunication unit 213 afterwards; Print unit 215 is accomplished signal according to creation data that receives and packing and is printed inventory (step 335), thus the completed product run flow process.
Since production control system inside solidification of the present invention hundreds of crop growth data of providing of expert; The soil data of local zones of different have also been imported simultaneously; Only need when the peasant buys fertilizer on guidance panel, to select crop varieties and planting area, programmable control system just can calculate suitable prescription automatically, and control appliance is accomplished blending process; Produce the suitable crop of peasant's needs and the compound fertilizer of soil texture; Specially for the peasant provides the technological guidance who surveys soil and rational application of fertilizers aspect, therefore crops and soil are had very strong specific aim as agricultural experts, help improving utilization rate of fertilizer.In addition, automated production can be saved great amount of manpower, has not only improved production of compound fertilizer efficient, and has significantly reduced production cost.
According to the announcement and the instruction of above-mentioned specification, those skilled in the art in the invention can also change and revise above-mentioned embodiment.Therefore, the specific embodiment that discloses and describe above the present invention is not limited to also should fall in the protection domain of claim of the present invention modifications more of the present invention and change.In addition, although used some specific terms in this specification, these terms are explanation for ease just, the present invention is not constituted any restriction.
