Embodiment

[0065] This compensation method is formed by the following steps:

[0066] The first step: signal acquisition, using the temperature, humidity and flow signals of the intake gas of the thermal air flow meter integrated with temperature, humidity and flow sensors at the same time, to collect multiple sets of data;

[0067] Step 2: Compare the value of the flow output signal of the thermal air flow meter with the value of the actual air flow provided, and study the change rule of the output signal of the air flow meter with the change of the intake temperature and humidity, and determine the utilization Feasibility of multiple linear regression model for signal offset correction;

[0068] Step 3: Analyze the collected raw data of temperature, humidity and flow signals as independent variable data (X T i ,X H i ,X F i ), i=1,...,n (n sets of data are collected, n is greater than or equal to the number of equation coefficients), and the actual intake flow rate is used as the...

Abstract

The invention provides a method, a method, device, storage medium, processor and system for compensating flow signal. The flow signal is a gas flow signal acquired by a gas flow meter, and the gas flow meter is also used for acquiring the temperature and the humidity of the gas. The method comprises the following steps: collecting a flow signal to be compensated of gas, the temperature of the gasand the humidity of the gas by using a gas flowmeter; and compensating the flow signal to be compensated according to the temperature and the humidity of the gas to obtain a compensated flow signal. According to the method, the detected flow signal is compensated according to the detected temperature and humidity of the gas, so that the compensated flow signal is closer to the actual flow signal,and relatively reliable and accurate data are provided for subsequent application.

Description

technical field [0001] The present application relates to the field of data processing, in particular, to a flow signal compensation method, device, storage medium, processor and system. Background technique [0002] In the development of today's automobile technology, the flow meter is a key component of the electronically controlled fuel injection system of the automobile. With the continuous improvement of vehicle emission standards, the performance requirements of vehicle air flow meters are also continuously improved, mainly in terms of high precision and stability. [0003] In the prior art, multi-sensor fusion technology has become the development trend of air flow meters, and data processing based on multi-sensor fusion air flow meters has become one of the current focuses. [0004] The air flow meter with multi-sensor fusion can monitor the temperature, humidity, flow and other signals of the intake gas in real time. The temperature and humidity of the intake gas ...
