In the present implementation, the sensor group includes a temperature sensor group, a pressure sensor group, and a flow sensor group;
the sensor data includes sensor usage data, sensor type data, sensor location data, and sensor real-time detection data.
In this embodiment, the sensor usage data includes water usage, oil usage, and gas usage, for example, a temperature sensor group may include a plurality of temperature sensors, but each temperature sensor may be responsible for different tasks, some for measuring oil temperature and some for measuring water temperature.
In this embodiment, the sensor data further includes flow field data, and the flow field data is obtained by sensor position data and sensor real-time detection data. In the embodiment, the flow field data is obtained by integrating sensor position data, real-time measurement data of the sensor and time.
In this embodiment, the obtaining the current engine operating condition according to the sensor data transmitted by the sensor group includes:
and acquiring the flow change of each flow sensor in the flow sensor group in a preset time period, and when the change of each flow sensor in each flow sensor is greater than a preset change threshold value, determining that the actual working condition of the engine is an air inlet insensitive working condition.
In this embodiment, for a total of two working conditions of the air path, one is an air intake insensitive working condition, and the other is an air intake stable state, in this embodiment, the reading of the air flow meter for air intake measurement in a short time does not change drastically, that is, the reading does not change drastically in this embodiment
Figure BDA0003659010450000051
In the present embodiment, if the intake air is in the intake air stable condition, the following formula is adopted to correct the data of the flow sensor:
Figure BDA0003659010450000052
the unit is kg/h, and M is the reading of a flowmeter sensor (namely the air flow measured by the flowmeter sensor);
Figure BDA0003659010450000053
representing a rate of change of a value of a flow meter sensor; where t represents time and M represents the flow meter sensor reading.
In the present embodiment, in a short time, the intake air amount is drastically changed,
Figure BDA0003659010450000054
in the implementation, if the actual air inflow and the air inflow measured by the sensor have larger deviation, the air inflow is considered to be an air inflow insensitive working condition, and in the implementation, the data of the flow sensor transmitted by the flow sensor group is corrected if the air inflow is in the air inflow insensitive working condition.
In this embodiment, other sensors may also be corrected, for example, after the flow sensor is corrected, the correction of all sensors after the sensor is the difference of the sensor. For example, if the position number of the sensor is 9 and the correction amount (the difference between before and after correction) is-2 hpa, the correction amount of the sensor number 9 is added to the value of all the flow sensors after the position number of 9, that is, -2 hpa.
In this embodiment, the flow sensor data is corrected using the following formula:

wherein the content of the first and second substances,
m is the air flow measured by the flowmeter sensor;
Figure BDA0003659010450000056
representing the rate of change of the value of the flow meter sensor.
It is understood that the temperature sensor may also be modified, and specifically, modifying for the temperature sensor includes:
when T is<The temperature is 60 ℃, the working condition of temperature stability is adopted,
Figure BDA0003659010450000061
when T is>The temperature is 60 ℃, is a temperature insensitive working condition,

Figure BDA0003659010450000063
is the rate of change of the value of the temperature sensor.
It can be understood that, the pressure sensor can be corrected, specifically, most of the pressure sensors have accurate values, and the degree of the individual gas circuit pressure sensor has large deviation from the actual value, and the pressure sensor is corrected:
when P is<When the pressure is 1350hpa, the pressure is high,
Figure BDA0003659010450000064
when P is present<When the pressure is 1350hpa, the pressure is high,
Figure BDA0003659010450000065
Figure BDA0003659010450000066
the unit is hpa; wherein, P is a pressure value,
Figure BDA0003659010450000067
is the rate of change of the value of the pressure sensor.
In this embodiment, the coupling the corrected respective sensor data with the three-dimensional model of the engine to form a coupled model includes:
acquiring position information of each sensor in each sensor group in a three-dimensional model of an engine to be detected;
and rendering the real-time detection data of the sensor of each sensor to the corresponding position of the sensor in the three-dimensional model of the engine to be detected.
Specifically, the stored data is coupled into the three-dimensional model, namely the position of numerical value display in the model is determined by reading the sensing position in the static data, and the unit of the type determination numerical value of the sensor is read (the temperature sensor corresponds to the temperature unit, the pressure sensor corresponds to the pressure unit, and the flow sensor corresponds to the flow unit); and reading the dynamic data to obtain the data measured by the corresponding position sensor at each moment.
In this embodiment, each flow field data is obtained as follows:
the path distance of every two adjacent sensors is measured by utilizing the positions of different sensors (water temperature sensors, oil temperature sensors, air flow and the like) relative to the three-dimensional model, the path distance is divided into a plurality of sections, and interpolation is carried out on each section, so that the flow field data of the whole path is formed.
The water temperature sensor is taken as an example below. Find out the temperature sensor number N in whole water route earlier, number water temperature sensor along the water route flow direction in proper order, the temperature sensor reading of water pump entry is marked as T 1 At a distance L from the water pump inlet point 1 … … until a water temperature sensor reading T occurs before returning to the pump along the water path N The distance LN the waterway flow passes through from the water pump inlet. The temperature function for each distance is calculated by linear interpolation:
Figure BDA0003659010450000071
thus, the temperature field of the whole water path can be calculated from 1 to N, and the data is stored in field data.
The physical parameters in the flow field are calculated by interpolation, and the temperature, pressure and flow velocity of any point in the flow field can be estimated.
Through the correction of various sensors, the model of the application can have more accurate data.
