Abstract
A paving machine can include a frame including a hopper; a screed coupled to the frame and including a screed plate; a first temperature sensor configured to measure a first temperature of a paving material in the hopper; a second temperature sensor to measure a second temperature of the screed plate; and a controller to receive the first and second temperatures and configured to determine an operating condition of the screed plate based on the first and second temperatures.
Claims15
A paving machine comprising:
- a frame including a hopper;
- a screed coupled to the frame and including a screed plate;
- a first temperature sensor configured to measure a first temperature of a paving material in the hopper;
- a second temperature sensor to measure a second temperature of the screed plate;
- and
- a controller including a database of expected screed plate thermal responses to a given screed plate temperature setting, the controller configured to receive the first and second temperatures, determine an operating condition of the screed plate based on the first and second temperatures, and determine if the screed plate is taking too long to heat up.
A method of monitoring a condition of a screed plate of a paving machine, the method comprising:
- measuring a first temperature of a paving material in a hopper of the paving machine;
- measuring a second temperature of the screed plate;
- and
- a controller determining, from the first and second temperatures as well as from a database of expected screed plate thermal responses to a given screed plate temperature setting:
- an operating condition of the screed plate based on the first and second temperatures, and
- whether the screed plate is taking too long to heat up.
