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

Abstract

The invention discloses a filter centralized control system. The system comprises a filter controller, wherein the filter controller is connected with an air filter pressure sensor, an air filter inlet PM sensor, an air filter outlet PM sensor, an air filter RFID label, an air filter antenna, a fuel oil filter inlet PM sensor, a fuel oil filter outlet PM sensor, a fuel oil filter RFID label, a fuel oil filter antenna, a machine oil filter inlet PM sensor, a machine oil filter outlet PM sensor, a machine oil filter RFID label and a machine oil filter antenna. The invention further discloses a filter centralized control method and a motor vehicle filter element bypass detection method. According to the system and the methods, the method that three filters are controlled in a centralized modecan be used for a motor vehicle, the controller is used for monitoring the three filters, the situation that a user uses a false filter element can be monitored, the user is reminded to replace a filter element in time before the filter element is scrapped, the machine oil filter RFID label is protected at the high temperature, the situation that the user mistakenly considers a novel filter element as an old filter element is prevented, the residual life of the filter element can be predicted, and the user can conveniently replace the filter element in time before the filter element 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
