In this embodiment, the NFC chip having the product serial number is installed on the genuine product identification unit and the filter element, and the filter includes the differential pressure sensor, the temperature sensor, the water level sensor, the fuel quality sensor, the GPRS module, and the satellite navigation module, which are installed on the filter, thereby forming a filter monitoring terminal. The filter monitoring terminal is connected with an electronic control unit ECU of the whole vehicle in a CAN bus communication mode through a local data storage interface, and is connected with a remote server through a wireless communication network, so that a filter monitoring system is formed.
The filter supervision system supervises the filter according to the following steps:
(1) the filter is provided with a genuine product identification unit, and the filter element is provided with an NFC chip at least storing a product serial number; the genuine product identification unit reads the product serial number in the NFC chip through NFC communication, acquires filter element product information at least comprising the product serial number, accesses a product database of the filter through a wireless communication network, and identifies and confirms whether the filter element is genuine.
If the filter element product used by the filter is detected to be not genuine, at least one of the following measures is taken to limit the normal use of the vehicle by a user:
(a) opening a condition lower limit braking force system of a corresponding authority and an interface in a whole vehicle factory to output torque;
(b) cutting off the oil way of the filter by controlling a solenoid valve arranged in the filter;
(c) the simulated filter provides false oil-water sensor signals to an automobile electronic control unit ECU, and the automobile electronic control unit ECU is forced to limit the power output of an engine and give an alarm on an instrument panel.
(2) In the case of confirming that the product is genuine, the pressure difference, water level, temperature and/or fuel quality information of the filter being operated is collected by the genuine recognition unit. The genuine product identification unit also collects GPS position information, mileage information and other data information which the finished automobile is willing to disclose of the vehicle provided with the filter through a vehicle CAN bus interface.
(3) The genuine identification unit transmits the collected pressure difference, water level, temperature and/or fuel quality information of the filter to a remote server through a wireless communication network through a SIM card for receiving;
(4) the remote server processes the acquired information of the pressure difference, the water level, the temperature and/or the fuel quality of the filter and monitors the filter in real time;
(5) the remote server pushes the recognition and confirmation result of the filter element quality product of the filter and the processing result of the pressure difference, the water level, the temperature and/or the fuel quality information of the filter to a user in the form of a mobile phone APP or a WeChat applet, or the whole vehicle/host factory/maintenance factory provides a webpage for the access of a client, or the client accesses through the client.
The filter supervisory system of the embodiment has the following functions:
1. genuine authentication
The function is the basic service of a filter monitoring system, the authenticity of a filter element of a filter replaced by a user is identified, and the authenticity result is fed back at the position of a filter seat in an LED indicating lamp mode; and the authenticity result is displayed at the instrument panel of the vehicle in a CAN bus communication mode, so that the right of knowing the authenticity of the purchased filter is ensured, and the user is guided to select the genuine filter.
The quality verification adopts a non-contact verification scheme based on NFC communication, and an NFC label chip and a coil with a product serial number are pre-embedded when the filter element leaves a factory. The filter monitoring terminal firstly reads the product serial number in the label chip through NFC communication to obtain filter information, and then accesses a company product database through a GPRS network to determine whether the current product is a genuine product.
If the current product is detected not to be a genuine product, the following measures can be taken to limit the normal use of the vehicle by the user: 1. the torque is output by the limited power system, and the function requires opening corresponding authority and interfaces of a whole vehicle factory; 2. the oil way of the filter is cut off, and the oil way is cut off by controlling an electromagnetic valve arranged in the filter, so that the function can be independently realized without the support of the whole vehicle factory; 3. the simulation filter provides oil-water sensor signals for the vehicle ECU, false signals are provided for the ECU, the ECU is forced to limit the power output of the engine and give an alarm on an instrument panel, and the function does not need the support of the whole vehicle factory and can be independently realized.
2. And (3) real-time monitoring:
the function is used for real-time monitoring and recording of the condition of the filter in the running process of the vehicle: the main state parameters of the filter, the operation state of a driver, the working condition state of the vehicle, the operation track of the vehicle and the like. This functionality may be for providing rich raw monitoring data;
in the first stage, the monitored quantities to be achieved are the filter element front-to-back pressure difference, the filter internal fuel temperature, and the vehicle position (based on base station information). Of the three quantities, the pressure difference and the temperature are collected through an analog-digital converter (ADC, see figure 2) on the intelligent terminal; and the vehicle position information is acquired through base station information provided by a telecom operator.
3. Statistical analysis:
the function is realized by carrying out deep mining and statistical analysis on the monitoring data, and further services such as the statistical analysis result of the state and the performance of a filter, the fault statistical analysis result and the like can be provided, the function can guide the design and development of subsequent products on one hand, and can be opened to a whole vehicle/whole machine plant to assist the whole vehicle/whole machine plant in optimizing the products, and can be opened to a maintenance plant to assist the maintenance plant in carrying out fault analysis and positioning on the whole vehicle/whole machine plant; the function can enhance the speaking right when the data interface is carried out with the whole vehicle/whole machine factory.
4. And (3) life estimation: the function realizes intelligent estimation of the service life of the filter element of the filter, and provides a more scientific filter service life result for an end user. The traditional filter life estimation is based on the driving mileage, and if the filter element filters fuel oil to reach a certain driving mileage, the filter element is considered to reach the service life and needs to be replaced; in fact, the service life of the filter is closely related to the service condition of the whole machine/vehicle, and incorrect service life estimation may cause the service life of the whole machine/vehicle to be shortened on the one hand, for example, the vehicle works under a heavy load or a congested road condition for a long time, although the specified mileage is not reached, the performance of the fuel filter is seriously reduced, and the wear of the whole machine/vehicle is aggravated due to untimely replacement; on the other hand, the use cost of the user can be increased, for example, when the vehicle runs on a light load or a smooth road section for a long time, although the specified mileage is reached, the performance of the fuel filter is not reduced remarkably, and the cost of the user is wasted when the fuel filter is replaced. The function can realize intelligent estimation of the service life of the filter in a more scientific mode, and directly pushes the information to a user, so that the user is helped to reduce the use cost of the whole vehicle in the whole life cycle, and the function is helpful for increasing the use viscosity of the system for the end user.
The above-mentioned embodiments of the present invention do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
