Description
Technical Field
The present invention relates to the field of vehicle manufacturing, and more particularly, to a system for automatically acquiring emission test data, a method for automatically acquiring emission test data, and a computer-readable storage medium.
Background
In the current vehicle production and manufacturing process, before the vehicle is delivered, a worker of a vehicle manufacturer randomly selects a vehicle on line to perform an emission test at random to check whether the emission performance of the vehicle meets the standard, and emission test data does not need to be submitted to the national government for supervision.
With the implementation of the latest standards of gasoline vehicle pollutant emission limit and measurement methods (dual idle speed method and simple operating condition method) (GB18285-2018), new requirements are put forward for vehicle selection, emission test data storage and upload, etc. of vehicle emission tests.
Disclosure of Invention
The object of the invention is to provide a system for automatically acquiring emission test data, a method for automatically acquiring emission test data and a computer-readable storage medium, which are capable of meeting at least some requirements of the latest automobile emission standards for vehicle emission tests, in particular the selection of emission test vehicles and the uploading of emission test data.
A first aspect of the invention provides a system for automatically acquiring emission test data, particularly during vehicle manufacturing, particularly prior to vehicle production, the system comprising a data processing module and a data acquisition module. The data processing module is configured to acquire master data of each vehicle, generate a test order according to the master data and a preset rule, and transmit the test order to the data acquisition module, wherein the test order comprises the master data and emission test information indicating whether to perform an emission test on the vehicle. The data acquisition module is configured to transmit the test order to the emissions testing device, to acquire emissions testing data for a vehicle undergoing an emissions test from the emissions testing device, and to transmit the emissions testing data to the data processing module. The data processing module is further configured to upload the emission 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 master data and the preset rule, the vehicle is not required to be randomly selected by a user, and the user management, such as modification or deletion, of the test order is facilitated. In addition, the data acquisition module independent of the data processing module transmits the test order and acquires the emission test data, so that the flexibility of the system can be improved, and the function expansion of the system is facilitated. After the emission testing equipment receives the testing order, the emission testing equipment can automatically perform emission testing on the vehicle which is conveyed to the emission testing equipment and needs to perform the emission testing, and the emission testing data is transmitted to the data acquisition module. The data acquisition module transmits the acquired emission test data to the data processing module, and the data processing module uploads the emission test data acquired from the data acquisition module to a predetermined external system. Therefore, the system can generate a test order containing emission test information on line and automatically acquire emission test data based on the test order, so that the emission test data can be processed according to the requirements of the latest automobile emission standard, for example, the emission test data is uploaded to a preset external system by a data processing module.
In an embodiment of the present invention, the Master data (Master data) of the vehicle includes at least a vehicle identification code, a vehicle model number, and a Type offer weight (TPG). Of course, the primary data of the vehicle may also comprise other basic data of the vehicle, such as emission stage, fuel type, OBD position, maximum total mass, part data, quality control data, etc.
In the embodiment of the present invention, the preset rule may be understood as a criterion for selecting a vehicle to be subjected to the emission test, that is, what kind of vehicle should be selected and how many vehicles should be selected to be subjected to the emission test. The preset rules may be associated with automotive emissions standards. For example, when the annual production of a vehicle manufacturer is greater than a predetermined number, e.g., 15, it is necessary to select at least 1% of the annual production of vehicles for emission testing; when the annual production is not greater than 15 vehicles, then all vehicles need to be tested for emissions. Preferably, the preset rules may relate to master data of the vehicle, in particular the vehicle model and the styling weight. For example, when the annual output of a vehicle manufacturer is greater than 15 vehicles, it is necessary to select vehicles with an annual output of at least 1% for emission testing, where vehicles of different vehicle models and different set weights each occupy a specific proportion of the 1% vehicles. The preset rules may be defined in advance by a user and stored in the data processing module. Furthermore, 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 also include process data of the emission test, an emission detection method, a report number, an emission detection date, emission detection equipment information, and the like.
In some embodiments of the system according to the invention, the data acquisition module may be further configured to store, in particular to store the emission test data for a long period of time, in order to meet the requirements of the new standard for data storage. For example, the data acquisition module is designed to be able to store at least fifteen years of data volume. Preferably, the data acquisition module has a database, such as an SQL server database, configured to store the emission test data, storing the emission test data in the form of an xml file.
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, such as a WEB server or an application server. Or both the data processing module and the data acquisition module can be implemented as a server. Of course, it is understood that the data processing module and the data acquiring module may also be implemented as program modules independent of each other, and 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-board diagnostic test refers to a test of the vehicle electronic device. In particular, for vehicles selected for emission testing, the on-board diagnostic test data includes on-board diagnostic test data relating to the emission test that is checked prior to the emission test. That is, for a vehicle that needs to be subjected to an emission test, it is necessary to perform not only a normal on-board diagnostic check but also a special on-board diagnostic check in which data related to the emission test is detected prior to the emission test. Further, the data acquisition module is also configured to store, in particular to store for a long time, the on-board diagnostic test data to meet the requirements of the new standard for data storage.
In some embodiments of the system according to the present invention, the data processing module and the data acquiring module may be independent of a production control system (an industrial control system of a production line) for controlling a vehicle production process, thereby enabling to reduce an influence on an existing production control system as much as possible on the basis of realizing automatic acquisition of emission test data, even without modifying the existing production control system, occupying no resources of the existing production control system, and ensuring stability of production control. In addition, the system adaptability can be improved, so that the system can be adapted to different vehicle manufacturers.
Preferably, the data processing module may also be configured to obtain master data for each vehicle from the production control system. The data processing module is also configured to transmit the test orders generated by the data processing module to the production control system, so that the production control system controls other production manufacturing processes, such as an on-board diagnostic check process. In this embodiment, only one data interaction interface needs to be newly designed in the existing production control system or modified so that the data interaction interface can perform data interaction with the data processing module, and the control stability of the production control system is not substantially affected and excessive resources of the production control system are not occupied.
Further, the data processing module and the data acquisition module can be independent of the emission testing equipment, so that the influence on the emission testing equipment can be reduced as much as possible on the basis of realizing automatic acquisition of the emission testing data, and the system adaptability is improved. In this case, it is only necessary for the emission testing device to design an interface for data interaction with the data acquisition module 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 in the emission testing apparatus.
In some embodiments of the system according to the invention, the data processing module and the data acquisition module may interact data via file sharing technology and/or web services technology and/or API gateway technology. Preferably, the data processing module and the data acquisition module exchange data by file sharing technology, thereby enabling simple and large-scale data interaction.
In some embodiments of the system according to the invention, the data acquisition module may transmit the test order to the emission testing device and acquire the emission test data from the emission testing device by file sharing techniques, thereby enabling a simple and relatively large amount of data interaction.
In some embodiments of the system according to the invention, the data processing module may also be configured for transmitting, e.g. automatically transmitting, the emission test data and/or the on-board diagnostic test data to a real-time monitoring system (RTM) of the vehicle manufacturer, preferably by means of message queuing technology and/or web service technology. 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 data needs to be transmitted to the government system, the real-time monitoring system uploads the data uniformly. Thus, the data processing module transmits the emission test data and/or the on-board diagnosis test data to the government system by using the real-time monitoring system, and the design of the data processing module can be simplified. Of course, the data processing module can also be provided with an interface for data interaction with a government system alone, i.e. the predetermined external system is the government system.
In some embodiments of the system according to the invention, the system for automatically obtaining emission test data according to the invention further comprises a terminal configured to access the data processing module through a user interface, preferably a web interface. Therefore, the user can manage the test order generated in the data processing module and the emission test data and/or vehicle-mounted diagnosis test data received from the data acquisition module through the terminal 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 to set and/or maintain preset rules for generating the test order by the data processing module. For example, a user may manually change the content of a preset rule on the rule setting component, such as changing the emission test proportion of a certain vehicle type.
In some embodiments of systems according to the present invention, the user interface may include a monitoring component configured to monitor a status of the emissions test. 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 the emissions test data and select the uploaded emissions test data. Thus, a user may be able to check for errors in the emissions test data before uploading the emissions test data to the 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 error free, the user may manually upload the emission test data via a submit button in the emission test data management component.
In some embodiments of systems according to the invention, the user interface may include an emissions test modification component configured to modify the emissions test information of the test order. For example, the user may manually change a vehicle that requires an emission test (hereinafter, referred to as an emission test vehicle) to a vehicle that does not require an emission test (hereinafter, referred to as a normal vehicle) or change a normal vehicle to an emission test vehicle on an emission test change assembly.
Optionally, the user interface may include a test cart modification component configured to modify the test cart to a normal vehicle or to modify the normal vehicle to the test cart.
A second aspect of the invention provides a method for automatically acquiring emission test data, the method comprising:
acquiring main data of each vehicle;
generating a test order according to the main data and a preset rule, wherein the test order comprises the main data and emission test information whether to perform an emission test on the vehicle;
transmitting the test order to an emission testing device;
acquiring emission test data of a vehicle subjected to an emission test from the emission test equipment;
uploading the emission test data to a predetermined external system.
According to the method, the test order containing the emission test information can be automatically generated according to the vehicle main data and the preset rule, and the emission test data can be automatically obtained according to the test order, so that the emission test data can be processed according to the latest automobile emission standard requirement, and the emission test data can be uploaded to a preset external system.
Further, the emission test data may be stored in a database, for example, for at least fifteen years, to meet the new standard requirements for data storage.
Further, the method may further include obtaining on-board diagnostic test data for each vehicle from an on-board diagnostic inspection device, the on-board diagnostic test data including on-board diagnostic test data relating to the emission test inspected prior to the emission test for the vehicle undergoing the emission test.
Preferably, the master data of the individual vehicles can be obtained from a production control system for controlling the production process of the vehicles.
In some embodiments of the method according to the invention, the test order may be transmitted to the emission testing device by file sharing technology and/or web service technology and/or API gateway technology, preferably by file sharing technology. Further, emission test data may be obtained from the emission test equipment via file sharing techniques. This enables a simple transfer of relatively large amounts of data.
Further, the step of uploading the emission test data to a predetermined external system may comprise transmitting the emission test data and/or on-board diagnostic test data to a real-time monitoring system of a vehicle manufacturer, preferably by message queuing technology and/or web services technology. The emissions test data and/or on-board diagnostic test data can thereby be transmitted to a 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 maintenance, such as modification instruction, of the preset rule by the terminal; and/or transmitting the emissions test status and/or the emissions test data to the terminal, preferably displayed on a user interface of the terminal. Therefore, the management of the preset rules and/or the emission test data on the user interface at any time and any place can be facilitated for the user.
The third aspect of the present invention also provides a method for automatically acquiring emission test data, in particular during vehicle manufacturing, for use with a system according to the first aspect of the present invention, the method comprising:
the method comprises the steps that a data processing module obtains main data of each vehicle, generates a test order according to the main data and a preset rule and transmits the test order to a data obtaining module, wherein the test order comprises the main data and emission test information whether to perform emission test on the vehicle or not;

Detailed Description
The technical solution 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 otherwise specifically noted, terms used herein should be understood as having meanings as commonly used in the art.
To meet the requirements of new regulations regarding reporting of emission test data, embodiments of the present invention first propose a system 110 for acquiring and transmitting emission test data, as shown in fig. 1 to 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 main data of each vehicle, for example, from the production control system 180 (also referred to as IPSL) through web service technology (for example, HTTP protocol), as shown in fig. 2. Here, the Master data (Master data) of the vehicle includes at least a Vehicle Identification Number (VIN), a vehicle model (Package), and a Type offer weight (TPG). In addition, the master data of the vehicle may also include a 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 a preset rule and transmit the test order to the data acquisition module 112, where the test order includes the main data and emission test information whether to perform an emission test on the vehicle. The predetermined rules may be understood here as a basis for selecting an exhaust vehicle. For example, a specific vehicle type (light, medium, and heavy), i.e., NRDC vehicle series, can be determined by the vehicle model and the set weight, and the NRDC vehicle series can be used as a standard basis for selecting an emission test vehicle, i.e., the emission test vehicle is selected according to the NRDC vehicle series.
In some embodiments, as shown in fig. 2 and 3, the data processing module 111 may actively push (as indicated by a solid arrow) the test order to the data obtaining module 112 through a web service technology (web service) or a File sharing technology (Network File System, NFS), or may transmit the test order to the data obtaining module 112 in response to a pull (pull) request (as indicated by a dashed arrow) of the data obtaining module 112.
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. Therefore, the influence on the production control system 180 can be reduced as much as possible, and the stability of production control can be ensured.
The data acquisition module 112 (also referred to herein as an emission testing module EMTS) is configured to transmit the test order to the emission testing device 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 the test order to the emission testing device 120 through, for example, a file sharing technology NFS, or may transmit the test order in response to a request from the emission testing device 120. Further, after the order file transfer fails, the transfer is attempted again, and Real time synchronization (Real time sync) is performed after the failed transfer attempt is repeated a predetermined number of times, for example, three times.
After the emission testing apparatus 120 acquires the test order, the emission test vehicle delivered to its location is subjected to an emission test 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 also include process data of the emission test, an emission detection method, a report number, an emission detection date, emission detection equipment information, and the like.
The data acquisition module 112 is also configured to acquire emission test data from the emission test equipment 120. As shown in fig. 2 and 3, the data acquisition module 112 may acquire the emission test data from the emission testing device 120 via a file sharing technique NFS, for example, the emission testing device 120 pushes the emission test result file to the data acquisition module 112 via the file sharing technique NFS after completing the emission test. That is, the data acquisition module 112 and the emission testing equipment 120 perform data interaction, preferably data interaction in real time, through the file sharing technology NFS.
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. Similarly, as shown in fig. 2 and 3, the data acquisition module 112 and the data processing module 111 may perform data interaction through a 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 particular example, the emission testing module EMTS may transmit a maximum of 10 data sets (test orders) per minute to the emission testing 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, before the vehicles are delivered, all vehicles must be transported to an OBD station 131 of an OBD (On-Board Diagnostics) inspection apparatus 130 for OBD inspection. OBD test result data also needs to be uploaded to the production system for monitoring and validation, and to government systems. Accordingly, the data acquisition module 112 is further configured to acquire OBD test data of each vehicle from the OBD inspection device 130 and 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 the NFS technology, and similarly, the data acquisition module 112 pushes the OBD test result data to the data processing module 111 through the NFS technology.
In particular, for a vehicle selected for an emission test, it is necessary to perform not only a conventional OBD check but also a special OBD check in which OBD data related to the emission test is detected, that is, the OBD test data includes OBD test data (COP OBD) related to the emission test checked before the emission test.
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 at the control layer or control system layer to other systems, such as the production control system 180. The order and process data management system 133 is at the so-called main control level, and all process data/order data from the individual systems are stored centrally 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 (casade), is provided. The order and process data management system 133 issues test orders to each client system 132 so that each OBD station 131 can know which vehicles need COP OBD inspection. After completion of the OBD inspection, 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 client system 132 or the order and process data management system 133 transmits the OBD test results to the data acquisition module 112, for example, via NFS techniques.
In some embodiments, as shown in fig. 3, to meet the requirements of the new standards for data storage, the data acquisition module 112 has a database configured to store emission test data and/or OBD test result data. The database is designed, for example, to be able to store at least fifteen years worth of data. For example, the data acquisition module 112 uses an SQL server database to store xml file data. The database may be divided into a year zone and a month table 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 and the number and inventory of vehicles.
As shown in fig. 1 and 4, to enable uploading of 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 acquired from the data acquisition module 112 to a predetermined external system, for example, to transmit the collected test result data to a real-time monitoring system 150(RTM) of 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, etc. The real-time monitoring system 150 receives data, for example, through its message queuing technology interface. The real-time monitoring system 150 integrates these data and then automatically uploads them to the government system 160, for example, in the form of an xml file. This makes it possible to meet the data delivery requirements in the new standard.
As shown in fig. 2 and 4, the real-time monitoring system 150 may also be configured to obtain the 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 before vehicle production, a production quality control system 170(IPSQ) is provided in the vehicle production manufacturing process, the production quality control system 170 being configured to monitor or manage various test results in the vehicle production manufacturing process. For example, the production quality control system 170 is configured to obtain the visual inspection results, the OBD test data, and the emission test data from the visual inspection 140, the order and process data management system 133, and the emission 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 production quality control system 170 obtains emission test data from the emission 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. 2 shows a schematic hardware architecture diagram of a vehicle production computer system comprising the system 110 of the present invention, wherein the data processing module 111 and the data acquisition module 112 are implemented as servers, e.g. application servers. In this embodiment, the data processing module 111 is a linux-based application server.
FIG. 5 illustrates a schematic flow chart of acquiring and uploading emissions test data and OBD test data in accordance with the present invention. First, several days, for example, 11 days before the vehicle enters the final assembly F0 point, a test order containing the master data and the emission test information is generated by the data processing module 111. When the vehicle passes point F0, the data processing module 111 sends a test order to the data acquisition module 112 while generating test plans (including emission tests and OBD tests) in the production quality control system 170. When the vehicle passes the offline F1 point and 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 the updated test order to the data acquisition module 112, the emission testing 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, before point F2, a corresponding test is performed according to the test plan generated in the production quality control system 170. For the selected emission test vehicles (for example, 1% of vehicles), the OBD test is performed at the OBD station 131, then the emission test is performed in the emission test equipment 120, and after the test is finished, the test results are respectively sent to the production quality control system 170 and the data acquisition module 112; for the rest vehicles which do not need to be subjected to the emission test, the OBD station 131 performs the OBD test, and after the test is finished, the test result is sent to the production quality control system 170 and the data acquisition module 112; checking whether the test data meets the requirements in the production quality control system 170; the data acquisition module 112 sends the emission test data and the OBD test data to the data processing module 111. When the vehicle reaches point F2, the data processing module 111 automatically transmits OBD test data to the real-time monitoring system 150, while emission test data is manually uploaded by the user to the real-time monitoring system 150 through a terminal described in further detail below.
As shown in fig. 1 and 2, the system 110 according to the invention further comprises a terminal 113 configured for accessing the data processing module 111 via a user interface.

Here, the user can manually edit (e.g., add, modify, or delete) the selection criteria via the edit button on the rule setting component. Furthermore, the user may also derive all criteria via the export button and view historical criteria, such as invalidation criteria, via the historical button.
As shown in FIG. 7, the user interface 113 may include a monitoring component 1132 configured to monitor the status of the emissions test, such as the completion progress of the emissions test. In the monitoring component 1132 shown in FIG. 7, a user may search for relevant emissions test conditions by vehicle model, NRDC train, and date. In addition, the monitoring component 1132 may display the emission test states in accordance with vehicle systems (F39, F49) and NRDC vehicle systems (BMW7156AS, BMW7206AS, BMW7206AX) in a classified manner. The emission test completion is displayed in percent in a status display icon for each NRDC train, where the first number represents the number of all emission test vehicles, the second number represents the on-line emission test vehicles, and the third number represents all vehicles of the NRDC train.
As shown in fig. 8, the user interface 113 may include an emissions test data management component 1133 configured to view the emissions test data and select the uploaded emissions test data.
