The present invention is based on the intelligent wheat water-absorbing of multi-data fusion and controls equipment, including moisture survey meter 106, Cheng Fenhou moisture survey meter 107, temperature sensor 108, unit weight sensor 109, display 110, keyboard 111 after master controller 101, Qian Tan road measurement apparatus 102, intensive dampener 103, Hou Tan road measurement apparatus 104, water valve 105, wheat wetting, wherein said master controller 101 includes water rate control module 1011 and data processing module 1012.Described Qian Tan road measurement apparatus 102 includes dry wheat water content survey meter and wheat flow sensor 203, records instantaneous dry wheat water content content and Semen Tritici aestivi flow respectively.Described Hou Tan road measurement apparatus 104 measures wet wheat water content content.Electromagnetic valve selected in embodiments of the present invention by described water valve 105, controls the size of water supply.The described keyboard 111 i.e. specific embodiment of the man-machine input interface 201 described in Fig. 2, input sets moisture and water rate control algorithm.Wherein, described water rate control algorithm is the rate of water added according to Semen Tritici aestivi, obtains the open degree of penstock.
Microwave remote sensor 202 in Fig. 2 is the specific embodiment of moisture survey meter 106 after the described dry wheat water content survey meter in the measurement apparatus of Qian Tan road described in Fig. 1 102, described Hou Tan road measurement apparatus 104, wheat wetting, Cheng Fenhou moisture survey meter 107.Wheat water-absorbing controls equipment at master controller 101 input input test signal (dry wheat water content, wet wheat water content, Semen Tritici aestivi flow etc.), master controller 101 changes according to the difference of wet wheat water content with set-point, makes the aperture size of penstock follow measured wet wheat water content value and automatically adjusts.Concrete, when wet wheat water content is higher than set-point, the aperture of penstock reduces under the control of master controller 101；When wet wheat water content is lower than set-point, the aperture of penstock increases, and makes the Semen Tritici aestivi moisture content after water not by the impact of the factors such as dry wheat water content, Semen Tritici aestivi flow and discharge, stable at expected value.
Wherein said Qian Tan road measurement apparatus 102 detect water before the moisture of dry Semen Tritici aestivi and flow velocity, for the coarse adjustment of rate of water added；Described Hou Tan road measurement apparatus 104 detects the moisture of the wet Semen Tritici aestivi after water, for the fine setting of rate of water added；After described wheat wetting moisture survey meter 106 with become powder after moisture survey meter 107 test the moisture after wheat wetting, this value is for the accurate debugging of rate of water added.
Concrete, when dry Semen Tritici aestivi flows through described Qian Tan road measurement apparatus 102 (moisture survey meter and wheat flow sensor 203), the signal of instantaneous moisture and Semen Tritici aestivi flow can be recorded respectively.Master controller calculates the wheat water content setting moisture value and actual measurement and flow that are previously implanted, the suitable flow obtaining answering water can be calculated, and the electromagnetic valve of execution part is sent coarse tuning instruction, supply water to intensive dampener 103 (also known as water hauling cage machine).
Concrete, it is located at intensive dampener 103 and exports the moisture of wet Semen Tritici aestivi after the described Hou Tan road measurement apparatus 104 i.e. microwave remote sensor 202 described in Fig. 2 of elephant trunk both sides can obtain water.Described master controller 101 is to specific humidity wheat water content and the moisture value set in advance, such as the variant accurate adjustment instruction namely sending the increase and decrease water yield to water supply mechanism and intensive dampener 103, and adopt least beat gradually to approach method to be adjusted, make water result be gradually reduced until being consistent with setting the difference required.After water result is consistent with setting, output remains unchanged；As produced difference, then proceed to adjust.
Scheme of the present invention has a lot of sensor, each sensor one data of extraction per second, form a huge data base.These sensor parameters are complicated to the influencing mechanism of wheat water-absorbing precision, have very big uncertainty, and very difficult conventional linear, Non-Linear Control Theory process.After carefully analyzing the intensity that wheat water-absorbing precision is affected by each sensor parameters, utilize fuzzy control method, each sensor parameters is carried out Fuzzy processing, forms the complex relationship formula of multi input data (after Semen Tritici aestivi temperature, Semen Tritici aestivi density, Semen Tritici aestivi flow, discharge, ambient temperature, ambient humidity, dry wheat water content content, wet wheat water content content, wheat wetting wet wheat water content content, Cheng Fenhou moisture etc.), output data (open degree of penstock).This relational expression does not need founding mathematical models, is that gamma controller provides one and is easier and highly effective implementation by multi-data fusion and FUZZY ALGORITHMS FOR CONTROL.
On the basis of automatic control powerful dampener 103, not only the inlet and outlet of intensive dampener 103 be equipped with detection moisture spy road, but also after adding wheat wetting, become latter two moisture survey meter of powder.Because after wheat wetting, water content detection (after 12～24 hours) becomes lag time of flour (longer than 24 hours lag time) water content detection very long with wheat processing, it is therefore desirable to the intelligent control scheme of Large-lag System.Semen Tritici aestivi after living water, need to by links such as wheat wetting (being generally 24 hours), wind send.The moisture loss amount of these link Semen Tritici aestivis and ambient air humidity, temperature have close relationship.Pass through fuzzy control method, after obtaining the general relationship of wheat water content loss amount and ambient air humidity, temperature, by measurement ambient air humidity, temperature, moisture loss amount can be fed back to described wheat water-absorbing in advance and control equipment, thus weakening, removing ambient air humidity, the temperature impact on wheat water-absorbing precision even completely.
Concrete, after being located at wheat wetting, Cheng Fenhou moisture detector can obtain the moisture of the wet moisture of Semen Tritici aestivi, flour after wheat wetting, Target moisture value and the described setting moisture value of described water controlling equipment are accurately adjusted by the data such as this large time delay data combining environmental air humidity, temperature.Cheng Fenhou moisture tester can obtain the difference of setting value and actual value, this difference is that the moisture that described Hou Tan road measurement apparatus 104 obtains is delayed (minimum is 24 hours) through for a long time, with the moisture variable quantity after surrounding (include ambient humidity, temperature, remove bran etc.) effect.Consider this variable quantity, it is simply that consider wheat water content content and environmental activity and the change that occurs.This difference is compensated target moisture content setting value, is greatly improved the moisture precision after powder process.
The present invention revises the measuring accuracy of various moisture further by unit weight sensor and temperature sensor.
Wherein, Semen Tritici aestivi density surveyed by described unit weight sensor, and Semen Tritici aestivi temperature is surveyed in described temperature sensor.Density and temperature are to affect two crucial factors of microwave measurement wheat water content precision.The relation of moisture precision can be obtained by density and temperature by actual measurement data, again through described unit weight sensor and described temperature sensor, can eliminate density, the temperature impact on wheat water content, thus improving the certainty of measurement of wheat water content.
Concrete, described unit weight sensor is also called bulk density tester, and its effect is the unit weight (i.e. a kind of method for expressing of density) measuring Semen Tritici aestivi.In the present invention, Semen Tritici aestivi is loaded in the container of a fixed volume, then measure empty and the weight difference of full container, unit weight (density) can be obtained.
Although illustrating it should be noted that the present invention controls equipment for wheat water-absorbing, but in actual applications, the principle of the program and structure can apply to any water device or water controlling equipment, it is not limited to this special kinds of Semen Tritici aestivi.
Wheat water-absorbing disclosed by the invention controls equipment, by Internet of Things, intelligent sensing equipment utilization is in wheat water-absorbing control equipment, stored by big data, analyze, process, understand wheat water-absorbing in depth, wheat wetting, cleaning, the links such as grinding, temperature, unit weight, atmospheric humidity, the impact on flour water content of the factors such as atmospheric temperature, develop a set of novel wheat with multisensor and water controlling equipment, wheat water content accuracy of detection dough-making powder working (machining) efficiency can be improved, reduce product cost, promote intellectuality and the visualization of wheat processing process, advance wheat processing industry development process.
