Embodiments of the present application will be described below with reference to the accompanying drawings.
The following explains an application scenario of the embodiment of the present application:
fig. 1 is an application scenario diagram of an engine performance monitoring method according to an embodiment of the present disclosure, as shown in fig. 1, a diesel engine 110 is used as a power plant of an automobile, and plays a role in the operation of the automobile, and whether the performance of the diesel engine 110 directly affects the operation condition of the automobile, so that the performance of the diesel engine 110 needs to be monitored. Most of the existing engine performance monitoring to be monitored is performed in an offline manner, the performance parameters of the diesel engine 110 are acquired through the sensor 120, the performance parameters of the diesel engine 110 at each moment are stored in the memory 130, and further, when a user finds that the diesel engine 110 is abnormal or reaches a time limit required to be detected, the performance parameters stored in the memory 130 for a period of time are copied through the offline analysis device 140, for example, for one week, one month and the like, and data analysis is performed according to the performance parameters to determine whether the performance of the engine to be monitored is abnormal.
However, the above off-line data analysis method results in a certain hysteresis in the monitoring of the engine performance parameters to be monitored, and the abnormal state cannot be detected in time.
In order to solve the above problems, an embodiment of the present application provides an engine performance monitoring method, which automatically determines whether the set performance of an engine to be monitored is abnormal or not by acquiring monitoring data of the set performance of the engine to be monitored in real time and according to a ratio of the real-time data to preset standard data, thereby implementing automatic monitoring of the performance of the engine to be monitored, and simultaneously improving timeliness of performance monitoring and safety of operation of the engine to be monitored.
Fig. 2 is a flowchart of an engine performance monitoring method provided in an embodiment of the present application, where the method may be executed by a server, and as shown in fig. 2, the engine performance monitoring method to be monitored specifically includes the following steps:
step S201, acquiring standard data of set performance of an engine to be monitored under various working conditions, and acquiring monitoring data of the set performance of the engine to be monitored under at least one working condition in a preset time period.
The operating conditions may include, among other things, the speed and torque of the engine to be monitored. The set performance can be any one or more performances of the engine to be monitored, such as the performances of the accelerator opening degree, the bearing temperature and the like of the engine to be monitored. The preset time period may be 12 hours, one day, or other time period.
Specifically, the standard data is data corresponding to the set performance of the engine to be monitored under various working conditions, namely, different rotating speeds and torques when the engine to be monitored normally operates.
Further, in the test process of the engine to be monitored, a large amount of effective experimental data of the set performance under various possible working conditions when the engine to be monitored is in a normal working state can be collected, and initial reference data of the rotating speed, the torque and the set performance is obtained so as to describe the data of the set performance under different rotating speeds and torques in the corresponding normal state.
Specifically, for each operating condition, the standard data may be an average value, a median value, a mode value, or other statistical values of the data of the set performance corresponding to the operating condition in the initial reference data.
Specifically, the monitoring data of the set performance of the engine to be monitored can be acquired in real time through sensors arranged around the engine to be monitored, and the monitoring data is sent to a server through a vehicle-mounted T-BOX (Telematics BOX) or other communication modes.
Further, after acquiring the monitoring data, the method further comprises: and eliminating abnormal data in the monitoring data. The abnormal data may be abnormal data caused by external factors, such as air humidity, temperature, and the like.
For example, taking the accelerator opening as an example, in the test process of the engine to be monitored, a large amount of effective experimental data under each working condition when the engine to be monitored is in a normal working state can be collected and used as initial reference data of the accelerator opening, and then the average value of the accelerator opening corresponding to each working condition in the initial reference data is used as the standard value of the accelerator opening under the working condition, so as to obtain the standard data of the accelerator opening. Fig. 3 is a schematic diagram of standard data of the accelerator opening degree in the embodiment shown in fig. 2, and fig. 3 only shows the standard data corresponding to the accelerator opening degree of the engine to be monitored under partial operating conditions. It can be seen that the standard data includes standard values of accelerator opening degrees corresponding to different torques and rotating speeds.
Step S202, aiming at each working condition, determining attenuation data of the set performance under the working condition according to the ratio of the monitoring data and the standard data under the working condition.
Specifically, the standard data corresponding to each actual working condition can be determined from the standard data according to various actual working conditions corresponding to the monitoring data, and then, for each actual working condition, the ratio of the monitoring data corresponding to the standard data is obtained and used as the attenuation data or attenuation value corresponding to the actual disclosure.
For example, assuming that the throttle opening corresponding to the standard data is 0.80 and the throttle opening corresponding to the monitored data is 0.86 and 0.88 respectively when the rotation speed is 1000 r/min and the torque is 600 Nm, the attenuation data in the working condition are respectively: 1.075 and 1.100.
Further, after determining the attenuation data of the set performance under each working condition, the method further comprises the following steps:
and displaying attenuation data under various working conditions.
Specifically, attenuation data under various working conditions can be displayed through a display screen of the vehicle-mounted entertainment system, the displayed specific form can be a curve graph, a straight bar graph and the like, abnormal degrees of the data can be labeled by different colors, for example, green represents a normal state, yellow, orange and red represent abnormal states, and the abnormal degree corresponding to the red is the highest.
Step S203, judging whether the set performance of the engine to be monitored is abnormal according to the attenuation data under each working condition.
Specifically, the degradation degree of the set performance of the engine to be monitored can be judged according to the attenuation data corresponding to each working condition, and whether the set performance of the engine to be monitored is abnormal or not can be judged according to the degradation degree.
For example, the main bearing temperature of the engine to be monitored is taken as an example, the main bearing temperature of the engine to be monitored under different rotating speeds and torques can be obtained by the online monitoring platform to serve as the monitoring data, then attenuation data corresponding to each working condition is obtained according to the ratio of the corresponding monitoring data of the main bearing temperature under each working condition to standard data, and then whether the main bearing temperature of the engine to be monitored is abnormal or not can be judged according to the attenuation data.
Optionally, when there is an abnormality in the set performance of the engine to be monitored, the method further includes: and generating and displaying prompt information.
Specifically, the prompt information can be sent to a relevant user terminal for displaying through the vehicle-mounted T-BOX, and can also be sent to a display screen of a station audio-visual entertainment system for displaying, so that relevant personnel can maintain the engine to be monitored according to the prompt information, the timeliness of abnormal state detection is improved, and the safety of the operation of the engine is ensured.
The engine performance monitoring method provided by the embodiment of the application obtains the monitoring data of the set performance of the engine to be monitored in a preset time period in real time, obtains the attenuation data of the set performance of the engine to be monitored in the corresponding working condition according to the ratio of the monitoring data to the standard data of the set performance with the same working condition, judges whether the set performance of the engine to be monitored is abnormal or not based on the attenuation data in each working condition, realizes the real-time monitoring of the starting performance, improves the timeliness of the abnormal starting performance reminding, and ensures the running safety of the engine to be monitored.
Fig. 4 is a flowchart of an engine performance monitoring method according to another embodiment of the present application, and as shown in fig. 4, this embodiment further refines step S201 and step S203 on the basis of the embodiment shown in fig. 2, and adds a step of updating standard data when there is no abnormality after step S203. The engine performance monitoring method provided by the embodiment comprises the following steps:
step S301, collecting data of the set performance of an engine to be monitored and a second engine with the same type as the engine to be monitored under various working conditions of historical time.
Wherein the second engine may be an engine of the same type and use as the engine to be monitored. The collected data is the initial reference data and represents the data of the set performance of the engine to be monitored and the second engine collected in historical time under various working conditions.
Step S302, aiming at each working condition, determining the standard data of the set performance of the engine to be monitored under the working condition according to the average value of the collected data of each engine of the set performance under the working condition.
Further, weights can be set for each engine, namely each second engine and the engine to be monitored, for each working condition, according to the weight and the collected data of each engine, a weighted average value corresponding to the working condition is calculated, and the weighted average value is determined as standard data of the set performance of the engine to be monitored under the working condition. Wherein the weight of the engine to be monitored may be the maximum of all weights.
Step S303, acquiring the monitoring data of the set performance of the engine to be monitored under at least one working condition in a preset time period.
Step S304, aiming at each working condition, determining attenuation data of the set performance under the working condition according to the ratio of the monitoring data and the standard data under the working condition.
Step S305, obtaining the average value, the maximum value and the minimum value of the attenuation data under each working condition in the preset time period.
Further, after the average value, the maximum value and the minimum value of the attenuation data corresponding to each working condition in the preset time period are obtained, a curve graph corresponding to the average value, the maximum value and the minimum value of the attenuation data under each working condition can be displayed.
For example, taking a preset time period as one day as an example, fig. 5 is a graph of attenuation data in the embodiment shown in fig. 4 of the present application, and as shown in fig. 5, a curve corresponding to the maximum value, the minimum value and the average value of attenuation data for each day of the set performance of the engine to be monitored may be displayed, a curve S1 in fig. 5 is a curve of the average value of attenuation data for each day of the accelerator opening of the engine to be monitored, a curve S2 is a curve of the minimum value of attenuation data for each day of the accelerator opening of the engine to be monitored, a curve S3 is a curve of the maximum value of attenuation data for each day of the accelerator opening of the engine to be monitored, the abscissa indicates the date, day 1 indicates day, and day 7 indicates day 7.
And S306, judging whether the set performance of the engine to be monitored is abnormal or not according to the average value, the maximum value and the minimum value of the attenuation data.
Specifically, when the average value, the maximum value and the minimum value of the attenuation data are all within the preset safety range, it is determined that the set performance of the engine to be monitored is normal, that is, no abnormality occurs.
Further, the preset safety range can be determined according to the value range of the collected data of the set performance, a default range can also be adopted, and the preset safety range can be adjusted according to the running environment of the engine to be monitored.
For example, assuming that the average value, the maximum value and the minimum value of the attenuation data corresponding to each day 7 days before the current day are all within the preset safety range, the average value of the attenuation data corresponding to the current day is beyond the preset safety range, and the maximum value and the minimum value of the attenuation data are both within the preset safety range, it is determined that the engine to be monitored is abnormal on the current day.
Optionally, the determining whether the set performance of the engine to be monitored is abnormal according to the average value, the maximum value and the minimum value of the attenuation data includes:
determining that there is an abnormality in the set performance of the engine to be monitored when at least one of the following conditions is satisfied for the average value, the maximum value, and the minimum value of the attenuation data: the average value of the attenuation data is larger than a set average value threshold; the maximum value of the attenuation data is greater than a set maximum value threshold; the minimum value of the attenuation data is greater than a set minimum threshold.
Specifically, the set average threshold, the set maximum threshold, and the set minimum threshold may be determined according to the acquired data corresponding to the set performance, may be set by default by the server, and may be adjusted according to actual requirements.
Step S307, when the set performance is not abnormal, updating the collected data according to the monitoring data of the set performance of the engine to be monitored.
Specifically, when it is determined that the set performance of the engine to be monitored in the preset time period is not abnormal according to the attenuation data, that is, when the set performance of the engine to be monitored is normal, the monitoring data corresponding to the set performance of the engine to be monitored can be uploaded to the server, the server updates the collected data of the engine to be monitored according to the uploaded monitoring data, and then updates the corresponding standard data according to the updated collected data. Through the data updating steps, the real-time updating of the standard data is realized, the accuracy of the standard data is improved, and the accuracy of the abnormal judgment is further improved.
And step S308, when the set performance of the engine to be monitored is abnormal, generating and displaying prompt information.
In the embodiment, historical data of the set performance of the engine to be monitored and a second engine with the same type and use under various possible disclosures are collected in a large quantity, the average value of the historical data corresponding to each working condition is determined as standard data of the set performance under the working condition, and the standard data is calculated through comprehensive data, so that the standard data can more represent the value of the set performance of the engine to be monitored under a normal state; the standard data are updated according to the monitoring data acquired in real time, so that the accuracy and the real-time performance of the standard data are further improved; based on the ratio of the monitoring data of the set performance of the engine to be monitored, which is acquired in real time, to the standard data, determining corresponding attenuation data, and judging whether the set performance of the engine to be monitored is abnormal or not according to the ranges of the average value, the minimum value and the maximum value of the attenuation data corresponding to each working condition of a preset time period, so that the automatic judgment of the abnormal state of the engine is realized, and the real-time performance and the accuracy of the monitoring of the engine are improved; meanwhile, attenuation data can be displayed in real time, and the visualization degree of the performance data of the engine to be monitored is improved; the engine performance monitoring method provided by the application has the advantages of good portability and strong expandability, and can be suitable for monitoring various performances of engines of various models.
