Monitoring the Quality of Work of Irrigation Machines with the Designed Speedmeter SM2 Device

Popis výsledku v původním jazyce

As we could see in the last few years, climatic conditions indicated a very low level of atmospheric precipitation. For this reason, it is necessary to deal with the issue of supplementary irrigation. On selected crops, we have to apply several doses of spray. We then focus on the quality of work of the used technology. Longitudinal spray uniformity is among the factors of the quality of work and it is also associated with the continuous and stable hose winding speed. To be able to assess the quality of the longitudinal uniformity of the speed of hose winding on the reel, we needed to design a digital device. The hardware design itself is not sufficient; therefore its software part needs to be added. The microcontroller PIC16F877 with the MOL30 tachometer was used as the main logic unit. The port RS232 was used for communication. After solving and constructing this device, we verified its functionality directly in the working conditions of a particular hose reel irrigation machine. The designed device Speedmeter SM2 enables saving of the data into the internal memory. It enables to store up to 122 values with setting up the time interval from 1 to 32768 sec. This device was verified in practical measurements, where an absolute error of the 0.34 m/hirrigator was found (relative error was 2.7% to the set value).
