Abstract

A filter monitoring system and method are described. The filter monitoring system includes a module or circuit installed on an internal combustion engine or within a vehicle powered by the internal combustion engine. The filter monitoring system monitors the operation of the various filtration systems present on the engine to determine an amount of service life remaining and a loading percentage for various filter cartridges installed in the filtration systems of the internal combustion engine. The filter monitoring system determines the loading percentage and predicts remaining service life of a given filter cartridge via a time-based manner (e.g., based on the installation date of the filter cartridge and filter cartridge life specifications) and a pressure differential based manner (e.g., based on a determination of pressure drop across the filter cartridge).

First claim

What is claimed is:

1. A monitoring system for a filtration system comprising:
a filter monitoring system circuit;
a telematics service circuit;
an engine control circuit of an internal combustion engine associated with the filtration system;
a first data link between the filter monitoring system circuit and the telematics service circuit; and
a second data link between the filter monitoring system circuit and the engine control circuit;
wherein the filter monitoring system circuit is configured to:
monitor a filter cartridge of the filtration system,
determine a pressure drop across the filtration system at a fluid flow rate through the fluid filtration system,
determine a first value indicative of a remaining filter life of a filter cartridge of the filtration system based at least in part on the determined pressure drop,
determine a second value indicative of the remaining filter life of the filter cartridge, the second value based at least in part on an amount of time the filter cartridge has been used in the filtration system, the second value determined in a different manner than the first value,
compare the first value to the second value to determine which of the first value or the second value indicates a least amount of life remaining for the filter cartridge, and
transmit, via the first data link, an indication of the least amount of life remaining for the filter cartridge to the telematics service circuit based on the comparison.

2. The system of claim 1 , wherein the first data link is a wireless data link.

3. The system of claim 1 , wherein the filter monitoring system circuit is further configured to receive, an identification of a parameter requested by the telematics service system from a listing of a plurality of parameters relating to the filtration system that are monitored by the filter monitoring system circuit.

4. The system of claim 3 , wherein the parameter is associated with an amount of life remaining for the filter cartridge.

5. The system of claim 1 , further comprising:
an electronic filter recognition circuit, wherein the filtration system comprises the electronic filter recognition circuit, and
wherein the filter monitoring system circuit is further configured to:
receive, from the electronic filter recognition circuit, an identifier associated with a radio frequency identity tag of the filter cartridge,
determine an installation date of the filter cartridge based on receiving the identifier, and
determine the amount of time the filter cartridge has been used in the filtration system based at least in part on the installation date.

6. The system of claim 1 , wherein the filter monitoring circuit is further configured to:
determine a first percent loading of the filter cartridge based at least in part on the determined pressure drop,
determine a second percent loading of the filter cartridge based at least in part on the amount of time the filter cartridge has been used in the filtration system, the second percent loading determined in a different manner than the first percent loading,
compare the first percent loading to the second percent loading to determine which of the first percent loading or the second percent loading indicates a higher percent loading of the filter cartridge, and
output an indication of the higher percent loading of the filter cartridge.

7. The system of claim 1 , wherein the filter monitoring circuit is further configured to transmit a second indication, via the second data link, to the engine control circuit of the internal combustion engine associated with the filtration system based on the comparison.

8. The system of claim 7 , wherein the transmitted second indication causes the engine control circuit to derate the internal combustion engine or prevent the internal combustion engine from starting.

9. A method comprising:
configuring, by a filter monitoring system circuit, a first data link between the filter monitoring system circuit and a telematics service system;
configuring, by the filter monitoring system circuit, a second data link between the filter monitoring system circuit and an engine control circuit of an internal combustion engine;
determining, by the filter monitoring system circuit, a first value indicative of a remaining filter life of a filter cartridge of a filtration system monitored by the filter monitoring system circuit, the first value based at least in part on a pressure drop across the filtration system at a fluid flow rate through the filtration system;
determining, by the filter monitoring system circuit, a second value indicative of the remaining filter life of the filter cartridge, the second value based at least in part on an amount of time the filter cartridge has been used in the filtration system, the second value determined in a different manner than the first value;
comparing, by the filter monitoring system circuit, the first value to the second value to determine which of the first value or the second value indicates a least amount of life remaining for the filter cartridge; and
transmitting, by the filter monitoring system circuit, an indication of the least amount of life remaining for the filter cartridge to the telematics service system based on the comparison.

10. The method of claim 9 , wherein the first data link is a wireless data link.

11. The method of claim 9 , wherein configuring the data link includes receiving, by the filter monitoring system circuit, an identification of a parameter requested by the telematics service system from a listing of a plurality of parameters relating to the filtration system that are monitored by the filter monitoring system circuit.

12. The method of claim 11 , wherein the parameter includes the amount of life remaining for the filter cartridge.

13. The method of claim 9 , further comprising:
receiving, by the filter monitoring system circuit and from an electronic filter recognition circuit of the filtration system, an identifier associated with a radio frequency identity tag of the filter cartridge;
determining, by the filter monitoring system circuit, an installation date of the filter cartridge based on receiving the identifier; and
determining, by the filter monitoring system circuit, the amount of time the filter cartridge has been used in the filtration system based at least in part on the installation date.

14. The method of claim 9 , further comprising:
determining, by the filter monitoring system circuit, a first percent loading of the filter cartridge based at least in part on the pressure drop across the filtration system at the fluid flow rate;
determining, by the filter monitoring system circuit, a second percent loading of the filter cartridge based at least in part on the amount of time the filter cartridge has been used in the filtration system, the second percent loading determined in a different manner than the first percent loading;
