The study is based on a one-year field try on the territory of Chirpan Region, in the central part of Bulgaria (42°09'07\"N25°20'54E). Experiments were conducted on two parcels with sizes – 1000 m length and 45 m width. The technological operation Plowing was carried out with a five-corpus turning plow, aggregated to a tractor with 200 hp at two speeds – 4.5 km/h and 6 km/h. The momentous soil moisture was measured with a soil moist meter AM-128 SOIL in different points of the experimental field before conducting the technological operation. The actual working depth received after the operation with the machine-tractor aggregate was measured using a linear meter. Based on the applied ANOVA it was established that the average values of the parameter Plowing Depth at both aggregate working speeds were statistically significant at a level p < 0.05. The correlation analysis registered strong positive relation between the Aggregate Speed and Plowing Depth (r = 0.923), as well as a strong negative correlation between the Soil Moisture and Aggregate Speed (r = -0.943), and between Soil Moisture and Plowing Depth (r = -0.860). A multivariate regression analysis was applied related to the influence of aggregate s working speed and soil moisture to keep the assigned plowing depth. Two regression models were compared (Linear and Non-linear). According to the received coefficients of determination, the Linear model (R2 = 0.968) described well the relations between the examined parameters, but the Non-linear model was more appropriate (R2 = 0.977). Taking into account the graphics describing the Non-linear regression model it was established that the assigned working depth of the machine-tractor aggregate could be kept at the moisture of 70-80% and aggregate speed of 4.5-5 km/h.","PeriodicalId":441906,"journal":{"name":"2022 8th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122339351","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To obtain the required raw data the system utilizes two main principles: the effect of humans on the WiFi signal strength and the entrance-exit control based on distance and LDR sensors. It is a low cost solution with quite good sensitivity and low error level. The simple principles which it is based on allows its application also in other areas like for example livestock farming, where the number of cattle entering a closed area can be counted.","PeriodicalId":441906,"journal":{"name":"2022 8th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126036774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
