Air compressor systems, upgrade kits, computer readable medium, and methods for controlling an air compressor for improved performance. The methods may include receiving a working air requirement; determining an estimated air pressure of the air compressor to deliver the working air requirement; measuring a pressure of the air compressor; comparing the measured pressure with the calculated estimated air pressure; if the measured pressure of the air compressor is greater than the determined estimated air pressure by a predetermined greater amount, then decreasing an output control of the air compressor; and if the measured pressure of the air compressor is less than the calculated estimated air pressure by a predetermined lesser amount then increasing the output control of the air compressor. The air compressor may be controlled based on a measured pressure of delivered working air. An oil control system may shut off oil to parts of the air compressor.

Air compressor system and method of operation

An autonomous drilling rig (), including a carriage including a mast (), a rotary head () configured to traverse up and down the mast (), and a wireless transmission system. The wireless transmission system includes a wireless transmitter () mounted on the rotary head () and configured to send a wireless signal to a wireless receiver (). The wireless transmitter () includes a first connector () configured to engage with a first sensor, wherein the sensor measures at least one operating parameter. The wireless transmission system further includes the wireless receiver () configured to receive the wireless signal from the wireless transmitter (), wherein the wireless signal comprises the at least one measured operating parameter, and a display unit () operatively connected to the wireless receiver () and configured to display the measured operating parameter.
