Description
Technical Field
The invention relates to remote monitoring of grain drying operation amount, in particular to a method for remotely monitoring batch grain drying operation amount.
Background
China is a large population country, and the problem of food is a big matter related to the national civilization. Grain drying is a complex heat and mass exchange process, and has the characteristics of multivariable, large hysteresis and strong nonlinearity from the system perspective. Grain drying operation is an important step in agricultural production, is also a key link in agricultural production, and is an important component for realizing the whole process mechanization of grain production. The mechanized technology for drying the rice takes mechanical drying as a main means, adopts corresponding processes and technical measures, artificially controls factors such as temperature, humidity and the like, and reduces the water content in the grains on the premise of not damaging the quality of the rice so as to ensure that the grains reach the national safe storage standard.
Agricultural production trusteeship is an agricultural operation mode that operating bodies such as farmers entrust all or part of operation links such as plowing, planting, preventing and collecting in agricultural production to a social service organization to complete under the condition of not circulating the land operation right. The management bodies such as small farmers receive the services of all or part of operation links such as unified centralized seedling raising, unified sowing, unified prevention and control, unified harvesting, unified drying and the like through production hosting, and the method is an important form of service scale management.
At present, agricultural machinery socialized service operations such as seedling cultivation, rice mechanical transplanting, overall prevention and control, drying and the like are developed in China for many years. The agricultural machinery socialization service needs to count the quantity and quality of the operation service of the socialization service main body, so that the operation subsidy of the operation main body can be relied on.
Grain drying of the existing operation main body is mostly fixed operation, and a grain drying machine adopting a batch circulating operation mode is adopted. The existing intelligent drying monitoring equipment only monitors the operation state of the dryer and cannot monitor the operation amount. Weighing monitoring is carried out before drying, so that the cost is high and data counterfeiting is easy to generate; the related departments adopt methods such as user signing of drying operation contract, electric energy consumption evaluation, workload investigation, remote grain flow weighing and the like to evaluate the drying workload, so that the time period is long, a large amount of manpower and material resources are consumed, the leakage and error are large during the monitoring of the drying workload, the fair, just and effective development of social service operation subsidy work is not facilitated, and a method with low cost and timely transmission of the drying workload is needed.

And calculating the specific installation position of the grain dryers with different bin capacities according to the size of the total bin capacity.
The further proposal is that the data control module records the date, the operation time, the moisture data and the bin capacity position during drying; a moisture tester obtains the moisture rho of the grains when the grains are put into a bin, and the unit is percent; according to the states of 4 bin sensors, the maximum positions of 50%, 80%, 90% and 100% of the bin sensors are bin capacity information of grains, the bin capacity information is used as bin capacity volume V, and the unit is m3。
The further proposal is that the batch grain drying work amount t = Vx (3.0207 Xrho + 533.65) ÷ 1000, wherein V is the volume of the bin volume, and m is the volume of the bin volume3(ii) a t is the drying capacity, ton; rho is grain moisture content percent. The grain moisture is more than 18 percent and the bin capacity is not less than 80 percent of the total bin capacity, and the time, the grain moisture and the bin capacity are recorded for 1 time at regular intervals; if the moisture of the grain is below 18 percent and the bin volume is less than 50 percent of the bin level, stopping recording; the data control module records the data as one-time operation process and effective operation amount data. The moisture content in the warehouse is less than 18%, and the condition of drying the dry grains possibly exists, and is not recorded; if the drying time is less than 5 hours, the data of the operation amount is not recorded.
The further scheme is that each device has a unique number and is matched with one dryer, and a plurality of dryers can share 1 set of data control module. The drying workload of the grain batches is transmitted by the data control module, the data control module has a wifi or 4G mode grid remote transmission mode, and transmits the data of moisture, operation time and bin capacity to the data receiving end for data statistics.

1. the cost is low. The machine can be used for acquiring moisture data by a moisture sensor, so that the cost of the sensor is not increased; the bin level sensor uses a material position sensor, so that the cost is low; the method is low in cost of the whole set of equipment, and meanwhile, a large amount of material resources consumed by manual statistics are saved through remote data transmission.
2. Integrity in time. The drying operation condition is continuously monitored by recording the operation date, the operation time, the moisture data and the state of the bin capacity position, and the operation amount condition can be timely counted.
3. And (4) effectiveness. The drying operation users can fill the drying bin as much as possible, the drying bin is not filled only when the last residual grains are insufficient, the grain drying operation amount is not recorded when the grain drying operation amount is less than 50 percent of the bin capacity, and the statistics of the total drying operation amount is not influenced. By timely transmitting the change records of the moisture and the bin capacity, the operation process is completely recorded, the operation amount is effectively recorded, and the cheating phenomenon of the grain drying operation amount can be effectively prevented.
