Filter centralized control system, filter centralized control method, and detection method for motor vehicle filter element bypass

Abstract

The invention discloses a filter centralized control system, comprising a filter controller connected with an air filter pressure sensor, an air filter inlet PM sensor, an air filter outlet PM sensor, an air filter RFID tag, and an air filter antenna , fuel filter inlet PM sensor, fuel filter outlet PM sensor, fuel filter RFID tag, fuel filter antenna, machine filter inlet PM sensor, machine filter outlet PM sensor, machine filter RFID tag and machine filter antenna; the invention also discloses a filter Centralized control method of motor vehicle filter and detection method of bypass of filter element of motor vehicle filter; the method of centralized control of three kinds of filters used in motor vehicle can be used in the present invention, one controller is used to monitor three kinds of filters, and the user can monitor the use of false For the condition of the filter element, remind the user to replace the filter element in time before the filter element is scrapped, protect the RFID tag of the machine filter at high temperature, prevent the user from mistaking the new filter element for the old filter element, and can predict the remaining life of the filter element, which is convenient for the user to replace the filter element in time before the life expires.

Description

technical field [0001] The invention relates to the technical field of motor vehicle filters, in particular to a centralized control method for motor vehicle filters. Background technique [0002] Air filters, fuel filters, and oil (ie, lubricating oil) filters are three types of filters that are necessary on a motor vehicle. The air filter plays an important role in ensuring the cleanliness of the engine intake, the fuel filter is used to ensure the cleanliness of the engine fuel, and the oil filter is used to ensure the cleanliness of the lubricating oil in the motor vehicle lubricating oil system. When each filter reaches the designed working time or working mileage, a new filter element needs to be replaced to ensure the normal function of each filter. [0003] Original filter elements are more expensive, so end users of motor vehicles sometimes replace non-original filter elements when replacing filter elements. Non-original filter elements vary from good to bad, and ...

AI Technical Summary

Problems solved by technology

When the original design tests the RFID tag of the filter element, the value of the filter element's working time and the filter element's working mileage value will be updated, which will cause the end user to mistakenly think that the filter element purchased or the filter element in the vehicle is not a new filter element

[0007] Frequent reading and writing of RFID tags in a high temperature environment can easily cause damage to RFID tags

The temperature of the engine oil (lubricating oil) may be higher than 70°C, so the working environment of the RFID label of the oil filter may damage the RFID label of the oil filter
