Thermal monitoring of trailers
Monitoring a critical parameter of a trailer and issuing a severity warning including: monitoring the critical parameter to be within one of a plurality of bands and issuing a different level of the severity warning based on which band of the plurality of bands the critical parameter falls into, wherein the critical parameter includes at least one of tire pressure, tire temperature, and brake temperature; and increasing an alert level of the severity warning by one, every hour, when the monitored critical parameter indicates continuous increase or decrease over time.
1 . A method for monitoring a tire pressure of a trailer and issuing a severity warning, the method comprising:
monitoring the tire pressure for a first low pressure band and a first high pressure band, wherein the first high pressure band is higher than the first low pressure band;
issuing a first severity warning when the tire pressure is within the first low pressure band or the first high pressure band;
monitoring the tire pressure for a second low pressure band and a second high pressure band, wherein the second low pressure band is lower than the first low pressure band, and the second high pressure band is higher than the first high pressure band;
issuing a second severity warning when the tire pressure is within the second low pressure band or the second high pressure band;
monitoring the tire pressure for a third low pressure band and a third high pressure band, wherein the third low pressure band is lower than the second low pressure band, and the third high pressure band is higher than the second high pressure band;
issuing a third severity warning when the tire pressure is within the third low pressure band or the third high pressure band; and
comparing the tire pressure with an average tire pressure of a set number of trips previously taken by the trailer.
2 . The method of claim 1 , further comprising
increasing an alert level of the severity warning by one, every hour, when the monitored tire pressure indicates continuous decrease over time.
3 . The method of claim 1 , further comprising
increasing an alert level of the severity warning by one, every hour, when the monitored tire pressure indicates continuous increase over time.
4 . The method of claim 1 , further comprising
increasing or decreasing the tire pressure by one psi for corresponding increase or decrease of 10° F. in ambient temperature.
5 . The method of claim 1 , further comprising
increasing or decreasing the tire pressure by 0.5 psi for corresponding increase or decrease of 1,000 feet in altitude.
6 . A method for monitoring a tire pressure of a trailer, the method comprising:
monitoring the tire pressure for a first low pressure band and a first high pressure band, wherein the first high pressure band is higher than the first low pressure band;
issuing a first severity warning when the tire pressure is within the first low pressure band or the first high pressure band;
monitoring the tire pressure for a second low pressure band and a second high pressure band, wherein the second low pressure band is lower than the first low pressure band, and the second high pressure band is higher than the first high pressure band;
issuing a second severity warning when the tire pressure is within the second low pressure band or the second high pressure band;
monitoring the tire pressure for a third low pressure band and a third high pressure band, wherein the third low pressure band is lower than the second low pressure band, and the third high pressure band is higher than the second high pressure band;
issuing a third severity warning when the tire pressure is within the third low pressure band or the third high pressure band; and
comparing the tire pressure with an average tire pressure of a set number of trips previously taken by a same or similarly-configured trailer.
7 . The method of claim 6 , further comprising
increasing an alert level of the severity warning by one, every hour, when the monitored tire pressure indicates continuous decrease over time.
8 . The method of claim 6 , further comprising
increasing an alert level of the severity warning by one, every hour, when the monitored tire pressure indicates continuous increase over time.
9 . The method of claim 6 , further comprising
increasing or decreasing the tire pressure by one psi for corresponding increase or decrease of 10° F. in ambient temperature.
10 . The method of claim 6 , further comprising
increasing or decreasing the tire pressure by 0.5 psi for corresponding increase or decrease of 1,000 feet in altitude.
