Abstract

A filtration monitoring system is an electronic system control module installed on an internal combustion engine or within a vehicle powered by the internal combustion engine. The filtration monitoring system monitors the health and status of the filtration systems present on the engine. The filtration monitoring system tracks filter loading patterns and predicts remaining service life of the filters by running smart algorithms based on sensor feedback (e.g., pressure sensor feedback, fluid quality characteristic sensor feedback, etc.). In some arrangements, the described filtration monitoring systems provide feedback as to whether a genuine (i.e., authorized, OEM approved, etc.) or unauthorized filter cartridge is installed in a given filtration system. The filtration monitoring system may be retrofit into an existing internal combustion engine or vehicle that does not already have a filtration monitoring system.

First claim

What is claimed is:

1. A filtration monitoring system module comprising:
a circuit board having a processing circuit, the processing circuit including a processor and memory, the processing circuit is structured to:
receive a feedback signal from each of a first pressure sensor related to a characteristic associated with a first filtration system that comprises a first filter cartridge, and a second pressure sensor related to a characteristic associated with a second filtration system that comprises a second filter cartridge,
analyze the feedback signal to determine a status of each of the first filter cartridge and the second filter cartridge,
calculate a percent loading of each of the first filter cartridge and the second filter cartridge based on the feedback signal from the first pressure sensor and the second pressure sensor, respectively, and
transmit data comprising each of the status and percent loading of each of the first filter cartridge and the second filter cartridge to a telematics system via an associated engine control module;
a housing formed around the circuit board, the housing partially encapsulating the circuit board, the housing defining an opening; and
a plurality of pins extending from the circuit board and into the opening,
wherein the second filtration system is a lube filtration system, and the characteristic associated with the lube filtration system comprises a quality of oil in the lube filtration system.

2. The filtration monitoring system module of claim 1 , wherein the circuit board includes at least seven analog input channels.

3. The filtration monitoring system module of claim 2 , wherein the circuit board includes ten analog input channels.

4. The filtration monitoring system of module claim 2 , wherein the circuit board includes a digital input channel.

5. The filtration monitoring system module of claim 1 , wherein the plurality of pins are arranged in two arrays.

6. The filtration monitoring system module of claim 1 , wherein the housing includes an alignment slot that ensures that the housing can only be installed on a connector in a single orientation.

7. The filtration monitoring system module of claim 1 , wherein the first filter cartridge is an air filter cartridge.

8. The filtration monitoring system module of claim 1 , further comprising an analog to digital converter circuit structured to convert the feedback signal from the first pressure sensor from an analog signal to a digital signal prior to analyzing the feedback signal from the first pressure sensor.

9. The filtration monitoring system module of claim 1 , further comprising an analog to digital converter circuit structured to convert each of the feedback signal from the first pressure sensor and the feedback signal from the second pressure sensor from an analog signal to a digital signal prior to analyzing each feedback signal from the first pressure sensor and the second pressure sensor.

10. The filtration monitoring system module of claim 1 , wherein the processing circuit is further structured to determine whether the first filter cartridge is a genuine air filter cartridge.

11. The filtration monitoring system module of claim 1 , wherein the processing circuit is further structured to determine whether the first filter cartridge is a genuine air filter cartridge and whether the second filter cartridge is a genuine fluid filter cartridge.

12. The filtration monitoring system module of claim 1 , wherein the processing circuit is further structured to:
receive, via a communicatively coupled radio frequency antenna, data from a radio frequency identifier tag installed on the first filter cartridge, wherein the data includes a unique identifier of the first filter cartridge;
determine whether the first filter cartridge is genuine based upon the received data; and
in response to determining that the first filter cartridge is not genuine, initiate an alert so as to indicate that the first filter cartridge is not genuine.

13. The filtration monitoring system module of claim 1 , wherein the processing circuit is further structured to:
receive, via at least one communicatively coupled radio frequency antenna, data from a radio frequency identifier tag installed on the second filter cartridge, wherein the data includes a unique identifier of the second filter cartridge;
determine whether the second filter cartridge is genuine based upon the received data; and
initiate an alert in response to a determination that the second filter cartridge is not genuine.
