What is asset monitoring?

Asset monitoring is another application in smart agriculture in which temperature sensing plays a critical role. In addition to monitoring the plants that are harvested, temperature sensors observe the equipment that gathers these plants. Temperature sensors send out alerts whenever an equipment system requires minor maintenance, is underperforming, or is critically failing. They’re used in nearly every predictive and reactive maintenance system to protect against overheating and detrimental failure.


What are temperature sensors used for?

Temperature Sensors are crucial in two key categories of smart agriculture — ambient condition monitoring and mechanical asset monitoring. Ice wine harvesting, for example, is known to occur within the narrow temperature window when ambient temperatures first reach between -10°C and -12°C during a harvesting season. Highly accurate temperature and humidity sensors and precise predictive temperature forecasts are imperative to the ice wine industry. Temperature sensors not only play a significant role in monitoring the ambient conditions of physical space, but they play an essential role in nearly all smart agriculture asset monitoring applications.


Why are pH sensors important?

In optimizing a plant’s growth potential and yielding highly productive harvests, it’s imperative to have a deep and quantitative understanding of the soil conditions from which agricultural products come. Using pH sensors provides critical feedback regarding soil nutrient deficiencies or the presence of unwanted chemicals. These sensors help smart agriculture monitor daily, weekly, monthly and annual fluctuations in soil pH and nutrient levels to continue to educate the agricultural industry.


What is the role of temperature sensors in agriculture?

Temperature sensors not only play a significant role in monitoring the ambient conditions of physical space , but they play an essential role in nearly all smart agriculture asset monitoring applications.


Why is GPS important for agriculture?

Typically associated with the automotive and cellular communication industries, GPS sensors are also advantageous to smart agriculture.

Modern GPS tracking of livestock has heightened the ability to monitor animals with a simple push of a button.


Why are accelerometers used in agriculture?

Similar to the use of temperature sensors in predictive maintenance, accelerometers are widely utilized across the smart agriculture industry to predict and assist with required maintenance. Primarily used on moving components and motors, accelerometers detect slight variations in movement and vibration inconsistencies and predict when standard maintenance is required or a compromised component needs replacement. Although not commonly associated with farming and other agriculture, accelerometers play a valuable role in the maintenance of vital smart agriculture equipment.


What is smart camera?

While smart camera technology is far from a stereotypical analog sensor, it has been increasingly adopted for a variety of smart agriculture applications. Companies such as Blue River Technology, a division of John Deere, have implemented smart camera technology to detect weeds and other plant locations to automatically and accurately dispense herbicides and fertilizer. This optimizes chemical utilization and increases overall productivity while decreasing chemical usage.


What are the limitations of tractors?

Macmillan 1.4 The overall limitations to performance are also explored in this book as follows: (i) At higher travel speeds the limit is engine stall (stopping); optimum engine loading and fuel consumption are achieved by appropriate choice of engine speed and gear ratio. (ii) At lower travel speeds in which the limit is wheel slip; the optimum wheel slip is achieved by an appropriate choice of the magnitude of the drawbar load also the weight on and size of the tyres, particularly on the driving wheels. (iii) On steep slopes and / or when an incorrect hitch is used; this instability (in the longitudinal plane) is overcome by limiting operation to appropriate slopes and using correct hitching. Other limitations (not directly associated with performance) such as the actual occurrence of longitudinal and lateral instability, and the loss of steering control due, for example, to vibration, are also beyond the scope of this book. 1.3 SYSTEMS AND POWER OUTLETS


What are the mechanics of tractors?

The Mechanics of Tractor – Implement Performance: Theory and Worked Examples – R.H. Macmillan 1.7 (ii) Walking tractor In the two-wheel or walking tractor (Figure 1.3) , the transmission usually consists of a variable speed V belt drive from the engine, which also acts as a clutch as it is tightened or loosened. A small gear-box may then be fitted, which in turn drives the wheels through chains. Such tractors are not usually fitted with a power take-off but while stationary may be used to drive equipment such as a pump. The belt drive to the wheels is removed and is used to drive the attached equipment directly. Power losses in the mechanical transmission systems of tractors are usually small, probably less than 10%. (b) Power take-off transm ission An (‘engine speed’) power take-off (PTO) which is frequently fitted to conventional tractors consists of a transmission from the engine to shaft which passes to the outside of the tractor, usually at the rear, and may be engaged to drive attached machines (Figure 1.2). The power passes from the engine through a friction clutch which is frequently operated with the same pedal as the transmission clutch. This, and an engaging mechanism, allows the drive to the power take-off to be stopped and started as required, independently from the drive to the wheels. Hence the driven machine may continue to operate and process the crop even though the tractor and machine are not moving forward. This is a very convenient arrangement and a great advantage over older tractors with a single clutch and especially over ground driven machines. PTO speed is determined by engine speed, (with a fixed ratio 3 or 4:1) irrespective of travel speed (traction transmission ratio). Power losses in the PTO drive are very small, usually less than 5%. A “ground-speed” PTO may also be fitted (Fig. 1.1). Here the drive to the PTO shaft is connected to the drive to the wheels after the traction transmission and hence the PTO speed changes as the traction transmission ratio is changed. The ground speed PTO rotates slowly (a few revolutions per unit distance traveled) and may be used as a replacement for a ground drive on machines such as seed drills where a fixed relationship between the movement of the tractor and the function of the machine is important. The two engaging mechanisms for the PTO drive are such that only one of these can be engaged at one time. (c) Hydraulic (oil) supply Here oil under pressure from a hydraulic pump, continuously driven by the engine, is available to operate linear actuators (cylinders, rams) usually for the purpose of controlling (raising and lowering) implements, or driving rotating actuators (motors). One such ram, in-built into the tractor, is used to raise the three-point linkage. Power losses in the hydraulic system may be moderate but are accepted because this outlet is a flexible and very convenient way of controlling machines and operating auxiliaries on the tractor and on attached machines. The details of the design and operation of the components in the three tractor transmission systems are covered in books on mechanical analysis and machine design. They will not be considered further in this book.


Why does traction transmission work?

Because the engine rotates at high speed (a few 1000’s of rpm) and the tractor wheels must operate at low speed (a few 10´s of rpm), the traction transmission has the function of reducing the speed of rotation of the engine to that required for the rear wheels.


What is an agricultural tractor?

1.1.1 General The agricultural tractor is one of the class of mobile machines that involves the ‘traction’ process.

What is differential unit?

Differential unit is a special arrangement of gears to permit one of the rear wheels of the tractor to rotate slower or faster than the other. While turning the tractor on a curved path, the inner wheel has to travel lesser distance than the outer wheel. The inner wheel requires lesser power than the outer wheel. This condition is fulfilled by differential unit, which permits one of the rear wheels of the tractor to move faster than the other at a turning point.
