Description
Technical Field
The present invention relates to the field of vehicle manufacturing, and more particularly, to a system for automatically acquiring emissions test data, a method for automatically acquiring emissions test data, and a computer-readable storage medium.
Background
In the current vehicle production and manufacturing process, before the vehicle reports production, a worker of a vehicle manufacturer generally randomly and randomly selects the vehicle to carry out emission test on line to check whether the emission performance of the vehicle meets the standard or not, and emission test data is not required to be submitted to the national government for supervision.
With the implementation of the latest standards of the gasoline vehicle pollutant emission limit value and measurement method (double idle speed method and simple working condition method) (GB 18285-2018), new requirements are put forward on vehicle selection of vehicle emission test, storage and uploading of emission test data and the like.
Disclosure of Invention
The object of the present invention is to provide a system for automatically acquiring emissions test data, a method for automatically acquiring emissions test data and a computer-readable storage medium which are capable of meeting at least a part of the requirements of the latest vehicle emissions standards on vehicle emissions tests, in particular the selection of emissions test vehicles and the uploading of emissions test data.
A first aspect of the invention provides a system for automatically acquiring emissions test data, in particular during vehicle manufacturing, in particular prior to vehicle production reporting, the system comprising a data processing module and a data acquisition module. The data processing module is configured to acquire main data of each vehicle, generate a test order according to the main data and a preset rule, and transmit the test order to the data acquisition module, wherein the test order comprises the main data and emission test information of whether to carry out emission test on the vehicle. The data acquisition module is configured to transmit the test order to the emissions test equipment, acquire emissions test data for the vehicle undergoing the emissions test from the emissions test equipment, and transmit the emissions test data to the data processing module. The data processing module is further configured to upload the emissions test data acquired from the data acquisition module to a predetermined external system.
In the system according to the invention, the data processing module generates the test order containing the emission test information according to the vehicle main data and the preset rules, the user does not need to randomly select the vehicle under the line, and the user can conveniently manage, for example, modify or delete the test order. In addition, the data acquisition module independent of the data processing module is used for transmitting the test order and acquiring the emission test data, so that the flexibility of the system can be improved, and the function expansion of the system is facilitated. The emission test device is capable of automatically performing an emission test on a vehicle requiring an emission test that is transported to the emission test device after receiving the test order, and transmitting emission test data to the data acquisition module. The data acquisition module transmits the acquired emission test data to the data processing module, which then uploads the emission test data acquired from the data acquisition module to a predetermined external system. Thus, by means of the system of the invention, it is possible to generate a test order containing emission test information on-line and to automatically acquire emission test data based on the test order, in order to subsequently process the emission test data according to the requirements of the latest emission standards of the vehicle, for example by uploading the emission test data to a predetermined external system by means of a data processing module.
In an embodiment of the invention, the primary data (MASTER DATA) of the vehicle includes at least a vehicle identification number, a vehicle model number, and a styling weight (Type approval weight, TPG). Of course, the main data of the vehicle may also include other basic data of the vehicle, such as emission phase, fuel type, OBD location, maximum total mass, part data, quality control data, etc.
In the embodiment of the present invention, the preset rule may be understood as a standard for selecting a vehicle to perform an emission test, that is, how vehicles should be selected and how many vehicles should be selected to perform the emission test. The preset rules may be related to automotive emissions standards. For example, when the annual production of a vehicle manufacturer is greater than a predetermined number, such as 15 vehicles, it is desirable to select vehicles with at least 1% annual production for emissions testing; when the annual production is not more than 15 vehicles, then all vehicles need to be subjected to emissions tests. Preferably, the preset rules may relate to the main data of the vehicle, in particular the vehicle model number and the set weight. For example, when the annual output of a vehicle manufacturer is greater than 15 vehicles, it is necessary to select vehicles with at least 1% annual output for emission testing, with the 1% vehicles each having a particular proportion of vehicles of different vehicle models and different styling weights. The preset rules may be predefined by the user and stored in the data processing module. In addition, the preset rules may also be managed, e.g., modified, by the user via the terminal, as will be described in more detail below.
In an embodiment of the present invention, the emission test data includes at least an emission test result or a final determination result. Further, the emission test data may further include process data of emission test, emission detection method, report number, emission detection date, emission detection device information, and the like.
In some embodiments of the system according to the invention, the data acquisition module may also be configured for storing, in particular for long-term storage, emission test data in order to meet the requirements of the new standard for data storage. For example, the data acquisition module is designed to be capable of storing data amounts of at least fifteen years. Preferably, the data acquisition module has a database, such as an SQL server database, configured to store emissions test data in the form of xml files.
In a preferred embodiment of the system according to the invention, the data processing module or the data acquisition module may be implemented as a server, for example as a WEB server or an application server. Or both the data processing module and the data acquisition module may be implemented as servers. Of course, it is to be understood that the data processing module and the data acquisition module may also be implemented as program modules independent of each other, which are not specifically limited herein.
In some embodiments of the system according to the present invention, the data acquisition module may be further configured to acquire on-board diagnostic test data for each vehicle from an on-board diagnostic (OBD) inspection device and transmit the on-board diagnostic test data to the data processing module. Here, the on-vehicle diagnostic inspection refers to inspection of vehicle electronics. In particular, for a vehicle selected for emissions testing, the on-board diagnostic test data thereof includes on-board diagnostic test data relating to emissions testing that was checked prior to the emissions testing. That is, for a vehicle that needs to be subjected to an emission test, not only a conventional on-vehicle diagnostic test but also a special on-vehicle diagnostic test in which data related to the emission test is detected is required to be performed before the emission test. Further, the data acquisition module is also configured for storing, in particular for long-term storage, of the on-board diagnostic test data in order to meet the requirements of the new standard for data storage.
In some embodiments of the system according to the invention, the data processing module and the data acquisition module may be independent of the production control system (industrial control system of the production line) used for controlling the production process of the vehicle, whereby the influence on the existing production control system can be reduced as much as possible on the basis of the realization of the automatic acquisition of emission test data, even without modifying the existing production control system, without occupying the resources of the existing production control system, thereby ensuring the stability of the production control. In addition, the system adaptability can be improved so as to adapt to different vehicle manufacturers.
Preferably, the data processing module may be further configured to obtain the main data of the respective vehicle from the production control system. The data processing module is further configured to transmit the test orders it generates to the production control system for the production control system to control other production manufacturing links, such as an on-board diagnostic check link. In this embodiment, only one data interaction interface needs to be newly designed in the existing production control system or the data interaction interface of the existing production control system needs to be modified, so that the data interaction interface can perform data interaction with the data processing module, the control stability of the production control system is not basically affected, and excessive resources of the production control system are not occupied.
Further, the data processing module and the data acquisition module may be independent of the emission test device, thereby enabling to reduce the influence on the emission test device as much as possible and to improve the system adaptability on the basis of realizing automatic acquisition of emission test data. Here, only an interface for data interaction with the data acquisition module has to be designed for the emission test equipment in order to receive test orders and to transmit emission test data. Of course, in other embodiments, the data processing module and/or the data acquisition module may also be integrated into the emissions testing device.
In some embodiments of the system according to the invention, the data processing module and the data acquisition module may interact with data via file sharing techniques and/or web services techniques and/or API gateway techniques. Preferably, the data processing module exchanges data with the data acquisition module via a file sharing technique, whereby a simple and relatively large amount of data interaction can be achieved.
In some embodiments of the system according to the invention, the data acquisition module may transmit test orders to and acquire emissions test data from the emissions test equipment by file sharing techniques, thereby enabling simple and relatively large data interactions.
In some embodiments of the system according to the invention, the data processing module may also be configured for transmitting emission test data and/or on-board diagnostic test data, for example automatically to a real-time monitoring system (RTM) of the vehicle manufacturer, preferably via message queuing techniques and/or web service techniques. That is, the predetermined external system is a real-time monitoring system of the vehicle manufacturer. The real-time monitoring system is a remote monitoring platform of a vehicle manufacturer and is mainly used for monitoring new energy vehicles. In addition, the real-time monitoring system is also provided with an interface for data interaction with a government system, and when the data needs to be transmitted to the government system, the data is uniformly uploaded by the real-time monitoring system. Therefore, the data processing module transmits emission test data and/or vehicle-mounted diagnosis test data to the government system by utilizing the real-time monitoring system, and the design of the data processing module can be simplified. Of course, the data processing module may also be separately provided with an interface for data interaction with a government system, i.e. the predetermined external system is a government system.
In some embodiments of the system according to the invention, the system according to the invention for automatically acquiring emissions test data further comprises a terminal configured for accessing the data processing module via a user interface, preferably a web interface. Thus, the user can manage the test orders generated in the data processing module and the emission test data and/or the on-board diagnostic test data received from the data acquisition module via the end user interface at any time and any place.
In some embodiments of the system according to the invention, the user interface may comprise a rule setting component configured for setting and/or maintaining preset rules for generating test orders by the data processing module. For example, a user may manually alter the content of a preset rule on the rule set component, such as altering the emissions test scale of a vehicle model.
In some embodiments of systems according to the present invention, the user interface may include a monitoring component configured to monitor the status of emissions testing. That is, the user may view the status of the current emissions test, such as the completion progress of the emissions test, through the monitoring component.
In some embodiments of systems according to the present invention, the user interface may include an emissions test data management component configured to view emissions test data and select uploaded emissions test data. Thus, a user can check for errors in emissions test data prior to uploading the emissions test data to a government system (e.g., via a real-time monitoring system), avoiding uploading erroneous emissions test data to the government system. After determining that the emission test data is free of errors, the user may manually upload the emission test data through a submit button in the emission test data management component.
In some embodiments of systems according to the present invention, the user interface may include an emissions test modification component configured to modify emissions test information of a test order. For example, the user may manually change a vehicle that needs to be subjected to an emission test (hereinafter referred to as an emission test vehicle) to a vehicle that does not need to be subjected to an emission test (hereinafter referred to as a normal vehicle) on the emission test changing component, or change the normal vehicle to an emission test vehicle.
Alternatively, the user interface may include a test vehicle modification component configured to modify the test vehicle to a normal vehicle or to modify the normal vehicle to a test vehicle.
A second aspect of the present invention provides a method for automatically acquiring emissions test data, the method comprising:
Acquiring main data of each vehicle;

Further, the emissions test data may be stored in a database, for example, for at least fifteen years, to meet new standards for data storage requirements.
Further, the method may further include acquiring on-board diagnostic test data of each vehicle from the on-board diagnostic test device, the on-board diagnostic test data including on-board diagnostic test data related to the emission test checked before the emission test for the vehicle performing the emission test.

Further, emission test data may be obtained from the emission test equipment through file sharing techniques. This enables a large amount of data to be transmitted in a simple manner.
Further, the step of uploading the emissions test data to a predetermined external system may comprise transmitting the emissions test data and/or the on-board diagnostic test data to a real-time monitoring system of the vehicle manufacturer, preferably via a message queuing technique and/or a web service technique. The emissions test data and/or the on-board diagnostic test data can thereby be transmitted to the government system using the interface of the existing real-time monitoring system.
In some embodiments of the method according to the invention, the method may further comprise: receiving a setting and/or maintaining, such as a modification instruction, of the terminal on the preset rule; and/or transmitting the emissions test status and/or emissions test data to the terminal, preferably displayed on a user interface of the terminal. Therefore, the management of the preset rules and/or emission test data on the user interface by a user can be facilitated at any time and any place.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Throughout the specification, unless specifically indicated otherwise, the terms used herein should be understood as meaning as commonly used in the art.
To meet the requirements of the new regulations regarding reporting emissions test data, embodiments of the present invention first provide a system 110 for acquiring and transmitting emissions test data, as shown in fig. 1-4. The system 110 includes a data processing module 111 and a data acquisition module 112.
The data processing module 111 is configured to obtain the master data of each vehicle, for example, from the production control system 180 (also referred to as IPSL) via a web service technology (e.g., HTTP protocol), as shown in fig. 2. The main data (MASTER DATA) of the vehicle includes at least a Vehicle Identification Number (VIN), a vehicle model number (Package), and a set weight (Type approval weight, TPG). In addition, the main data of the vehicle may also include a Model number (Model) and a Model description (Type).
The data processing module 111 is further configured to generate a test order according to the acquired main data and preset rules and transmit the test order to the data acquisition module 112, wherein the test order comprises the main data and emission test information whether to perform an emission test on the vehicle. The preset rules are understood here to be the basis for selecting the discharge vehicle. For example, a specific vehicle model (light, medium, and heavy), i.e., an NRDC train, can be determined by vehicle model and styling weight, and the NRDC train can be used as a standard basis for selecting an emissions test vehicle, i.e., the emissions test vehicle is selected according to the NRDC train.
In some embodiments, as shown in fig. 2 and 3, the data processing module 111 may push (as indicated by solid line arrows) the test order to the data acquisition module 112 actively (push) through a web services technology (web services) or a file sharing technology (Network FILE SYSTEM, NFS), or may transmit the test order to the data acquisition module 112 in response to a pull (pull) request from the data acquisition module 112 (as indicated by dashed line arrows).
The data processing module 111 is preferably independent of the production control system 180, and the data processing module 111 may also be referred to herein as an extension module IPSL _ext of the production control system 180. Thereby minimizing the influence on the production control system 180 and ensuring the stability of production control.
The data acquisition module 112 (which may also be referred to herein as an emissions test module EMTS) is configured to transmit the test order to the emissions test equipment 120 after the test order is acquired from the data processing module 111. As shown in fig. 2 and 3, the data acquisition module 112 may actively push a test order to the emission test device 120, for example, through file sharing technology NFS, although it may also be transmitted in response to a request from the emission test device 120. In addition, after the order file transfer fails, the transfer is attempted again, and real-time synchronization is performed after the transfer is repeatedly attempted a predetermined number of times, for example, three times (REAL TIME SYNC).
After the emission test apparatus 120 acquires the test order, an emission test is performed on the emission test vehicle delivered to its location to acquire and record emission test data in association with the number of the test order or the vehicle identification number in the test order. Here, the emission test data includes at least an emission test result or a final determination result. Further, the emission test data may further include process data of emission test, emission detection method, report number, emission detection date, emission detection device information, and the like.
The data acquisition module 112 is also configured to acquire emissions test data from the emissions test equipment 120. As shown in fig. 2 and 3, the data acquisition module 112 may acquire the emission test data from the emission test device 120 through the file sharing technology NFS, for example, the emission test device 120 pushes the emission test result file to the data acquisition module 112 through the file sharing technology NFS after the emission test is completed. That is, the data acquisition module 112 and the emissions test equipment 120 interact with each other via file sharing technology NFS, preferably in real time.
After acquiring the emission test data, the data acquisition module 112 is further configured to transmit the emission test data to the data processing module 111. Likewise, as shown in fig. 2 and 3, the data acquisition module 112 and the data processing module 111 may perform data interaction through the file sharing technology NFS. That is, the data acquisition module 112 actively pushes the emission test data to the data processing module 111 through the NFS technology, but may be transmitted in response to a request of the data processing module 111.
In one specific example, the emissions test module EMTS may transmit a maximum of 10 data sets (test orders) per minute to the emissions test equipment 120. The emission test module EMTS transmits a maximum of about 45 result data sets (emission test results) per minute to the data processing module 111.
Likewise, the data acquisition module 112 is preferably completely independent of the production control system 180 in order to minimize or even avoid impact on the production control system 180.
As shown in fig. 1, all vehicles must be transported to the OBD station 131 of the OBD (On-Board Diagnostics, on-board diagnostic) inspection device 130 for OBD inspection prior to delivery of the vehicle. OBD test result data also needs to be uploaded to the production system for monitoring and validation and uploaded to a government system. Accordingly, the data acquisition module 112 is further configured to acquire OBD test data of each vehicle from the OBD inspection device 130 and to transmit the OBD test data to the data processing module 111. In the embodiment shown in fig. 3, the OBD inspection device 130 pushes the OBD test result data to the data acquisition module 112 through NFS technology, and likewise, the data acquisition module 112 pushes the OBD test result data to the data processing module 111 through NFS technology.
In particular, for vehicles selected for emission testing, it is not only necessary to perform a conventional OBD check, but also to perform a special OBD check prior to emission testing, in which OBD data related to emission testing is detected, i.e. OBD test data includes OBD test data (COP OBD) related to emission testing, which is checked prior to emission testing.
To this end, the data processing module 111 is further configured to transmit the test orders it generates to the production control system 180, so that the production control system controls other production manufacturing links, such as an OBD inspection link. The production control system 180 sends the test order from the data processing module 111 to the order and process data management system 133 (APDM). Here, the order and process data management system 133 is an interface for transmitting process data/order data to other systems, such as the production control system 180, at the control layer or control system layer. The order and process data management system 133 is in a so-called master control layer, and all process data/order data from the various systems is centrally stored in the order and process data management system 133 and transmitted to the target system via a standard interface. At each OBD station 131 a client system 132, for example a Java based client system (CASCADEs), is provided. The order and process data management system 133 issues test orders to each customer system 132 so that each OBD station 131 can know which vehicles need COP OBD checks. After the OBD check is complete, the client system 132 transmits the OBD test results to the order and process data management system 133, and the client system 132 or the order and process data management system 133 transmits the OBD test results to the data acquisition module 112. As shown in fig. 2 and 3, the customer system 132 or the order and process data management system 133 transmits OBD test results to the data acquisition module 112, for example, via NFS technology.
In some embodiments, as shown in FIG. 3, to meet the requirements of the new standard for data storage, the data acquisition module 112 has a database configured to store emissions test data and/or OBD test result data. The database is for example designed to be able to store data amounts of at least fifteen years. For example, the data acquisition module 112 uses an SQL server database to store xml file data. The database may be divided into annual zones and month tables in order to achieve efficient storage of data. At the same time, a backup mechanism is used to ensure data integrity.
Further, in an embodiment not shown, the data processing module 111 may be configured to obtain the results of the visual inspection 140 as well as the number and inventory of vehicles.
As shown in fig. 1 and 4, to be able to upload the collected various test result data to the government system 160, the data processing module 111 may also be configured to upload the emission test data obtained from the data acquisition module 112 to a predetermined external system, such as a real-time monitoring system 150 (RTM) that transmits the collected test result data to a vehicle manufacturer. The data collected by the data processing module 111 includes emissions test data, OBD test data and visual inspection results, vehicle numbers and checklists, and the like. The real-time monitoring system 150 receives data, for example, through its message queuing technique interface. The real-time monitoring system 150 integrates this data and automatically uploads it to the government system 160, for example, in the form of xml files. Thereby being capable of meeting the datagram requirements in the new standard.
As shown in fig. 2 and 4, the real-time monitoring system 150 may also be configured to obtain primary data of the vehicle from the SAP system 190. In the embodiment shown in fig. 4, the real-time monitoring system 150 has a database for storing uploaded data files and report archive files.
In addition, as shown in fig. 1 and 3, in order to ensure that all vehicle test or inspection results are satisfactory prior to vehicle production, a production quality control system 170 (IPSQ) is also provided in the vehicle manufacturing process, the production quality control system 170 being configured to monitor or manage various test results in the vehicle manufacturing process. For example, the production quality control system 170 is configured to obtain the visual inspection results, OBD test data, and emissions test data from the visual inspection 140, the order and process data management system 133, and the emissions test module EMTS, respectively, so that a user can monitor and confirm whether these result data are correct. In the embodiment illustrated in FIG. 3, the quality of production control system 170 obtains emissions test data from the emissions test module EMTS via a remote Call (Call procedure). In addition, the production quality control system 170 also has a database for storing data.

Fig. 5 shows a schematic flow chart of acquiring and uploading emissions test data and OBD test data according to the present invention. First, a test order containing the main data and emission test information is generated by the data processing module 111 several days, for example 11 days, before the vehicle enters the final assembly F0 point. As the vehicle passes through point F0, the data processing module 111 sends the test order to the data acquisition module 112, while generating a test plan (including emissions tests and OBD tests) in the production quality control system 170. When the vehicle passes the off-line F1, the vehicle needs to be weighed, the data processing module 111 updates the test order (data related to the weight in the test order) according to the new weight of the vehicle and sends it to the data acquisition module 112, the emission test device 120 acquires the test order from the data acquisition module 112, and the OBD station 131 acquires the test order from the corresponding module or system. Then, corresponding tests are performed in accordance with the test plan generated in the production quality control system 170 prior to reporting the production F2 point. For a selected emission test vehicle (e.g., 1% of vehicles), an OBD test is performed at the OBD station 131, then an emission test is performed in the emission test device 120, and after the test is finished, test results are sent to the production quality control system 170 and the data acquisition module 112, respectively; for the rest vehicles which do not need to be subjected to emission test, performing OBD test at the OBD station 131, and after the test is finished, sending a test result to the production quality control system 170 and the data acquisition module 112; checking in the production quality control system 170 whether the test data are satisfactory; the data acquisition module 112 sends the emissions test data and the OBD test data to the data processing module 111. When the vehicle reaches the report F2 point, the data processing module 111 automatically transmits OBD test data to the real-time monitoring system 150, and the emission test data is manually uploaded to the real-time monitoring system 150 by the user through a terminal described in further detail below.
