Description

TECHNICAL FIELD

[0001] The present application relates to the field of engine test bed, and more particularly, to a test bed on-site interaction method and system. BACKGROUND

[0002] Engine ground test bed is a special complete set of equipment for testing various performance indicators of an engine. During the test process of the engine test on the test bed, due to the complexity of the equipment, the limited time and space on site, and other reasons, it is not possible for multiple people to operate or troubleshoot during the test process, and generally a single person or a few people operate. Due to the high complexity of technology and equipment, in some cases, the on-site operator cannot make a technical judgment, but needs to be handled offline, and the next step is performed after the situation is found out, which is a complex and slow process.

[0003] In addition, due to the need for the operator to describe and repeat, some important features of the test bed test may be overlooked, resulting in repeated work and low efficiency. For some special and unexpected problems, timely and accurate judgments and appropriate operations cannot be made, and the problem may not be reproduced, resulting in failure to solve the problem in the early stage and causing serious losses in the later stage. On the other hand, the traditional remote monitoring and testing method and system of the test bed have a guiding effect on mature products, but for products, equipment or systems under development, it cannot well solve the actual problems on site.

[0031] Figure 1 A schematic diagram of a test stand work scenario 100 is shown in accordance with an embodiment of the present application. An engine test stand can include various equipment (referred to as test equipment) for conducting engine tests, including but not limited to an engine test stand, a fuel control supply system, an air control supply system, a monitoring and alarm system, etc. An engine can be mounted on the test stand, the fuel control supply system can supply fuel to the engine, and the air control supply system can supply air to the engine, so that the engine can be tested.

[0032] The engine test stand can also include test data acquisition equipment for acquiring various parameters related to engine tests. The test data acquisition equipment can include various sensors, which can be mounted or embedded on various test equipment of the test stand and / or connected to the engine.

The test data acquired by the test data acquisition equipment can also be displayed on the operation panel of the test stand for use by on-site personnel.

[0033] During the engine test, one or more workers can be present at the site to operate, for example, to control the experimental parameters, to observe the experimental results, to detect and repair faults, etc. According to an embodiment of the present application, the workers present at the site can carry or wear a mobile terminal which can collect the site environment data of the test bed, such as images (e.g., images or videos of the equipment or a part thereof) and / or audio data (e.g., noise of the test bed, engine) of the experimental equipment and / or engine, images and / or audio data of the environment around the test bed, etc. As an example but not limitation, the mobile terminal can include one or more of the following: an audio sensor, a camera, a temperature sensor, a humidity sensor, a pressure sensor, an oxygen concentration sensor, or a tag sensor, etc. Due to the site reasons and convenience, the mobile terminal can be small enough and convenient to carry. As an example but not limitation, the mobile terminal can be integrated on a helmet, glasses, earphones, a microphone, gloves, etc. Accordingly, the mobile terminal can be close to the position near the eyes and ears of the workers, realizing what you see is what you get, and the video acquisition range coincides with the field of view range.

[0034] The site environment data can be stored and / or transmitted to other devices, such as processors, servers, etc. The mobile terminal can include a wireless communication interface for communicating with a remote terminal, a remote controller or a remote server. The wireless communication interface can include one or more of the following: WIFI, Bluetooth, USB, cellular interface (e.g., traditional cellular wireless communication system, LTE communication system, 5G NR communication system, etc.).

[0035] Figure 2 A block diagram of a test bed site interaction system 200 according to an embodiment of the present application is shown. The test bed site interaction system 200 can be applied to a test bed scene, in which the test bed can include various experimental equipment 210 to conduct tests on an engine 220, and can include experimental data acquisition equipment 212 to acquire experimental data of the engine experiments conducted on the test bed. The experimental data acquisition equipment 212 can include a variety of sensors, which can be installed or embedded on various experimental equipment 210 of the test bed, and / or connected to the engine 220. The experimental equipment 210 can include, for example, an engine test bed, a fuel control supply system or a subsystem thereof, an air control supply system or a subsystem thereof, a monitoring alarm system, etc. For example, the experimental data acquisition equipment 212 can acquire one or more of the following information: operating parameter information of the engine; parameter information of the engine test bed; fuel parameter information in the fuel control supply system of the test bed; air parameter information in the air control supply system of the test bed; monitoring alarm information provided by the monitoring alarm system.

[0036] Further, as described above, the mobile terminal 230 can be present in the test cell to collect live environment data of the test cell. The live environment data collected by the mobile terminal 230 can include one or more of the following: image and / or audio data of the experimental equipment 210 and / or the engine 220, image, audio, temperature, and / or humidity, etc. of the environment surrounding the test cell.

[0037] The test cell live interaction system 200 can include a server 250, which can communicate with the mobile terminal 230, the experimental equipment 210 of the test cell, the experimental data collection equipment 212, etc. For example, the server 250 can receive live environment data of the test cell from the mobile terminal 230, receive experimental data of the engine from the experimental data collection equipment 212, deliver control instructions to the mobile terminal 230 and / or the experimental data collection equipment 212, etc.

[0038] In one embodiment, the server 250 can generate a live model of the test cell based on configuration information of the test cell. The configuration information of the test cell can be received from the experimental equipment 210 of the test cell, the operator control panel, and / or other electronic devices. The configuration information of the test cell can include, for example, configuration information of each experimental equipment 210, configuration information of the engine 220, configuration / parameter information of the engine experiment to be conducted or being conducted, etc. The live model generated by the server 250 can include a model of the engine and a model of the experimental equipment of the test cell. As an example and not a limitation, the live model of the test cell can be a three-dimensional model or an animated model containing various equipment in the test cell scene and their parameter information, and optionally containing audio information.

[0039] The test cell live interaction system 200 can include one or more remote terminals 260 through which one or more remote users can access the server 250, for example, to access the live model of the test cell. The remote terminal 260 can be a mobile phone, a tablet, a desktop computer, etc. communication device. As an example and not a limitation, the remote terminal 260 can include user interface devices, for example, input devices and / or output devices. The live model of the test cell generated by the server 250 can be presented on the remote terminal 260. The remote terminal 260 can also receive user input data and provide operation instructions based on the user input data via the server 250 and the mobile terminal 230.

[0040] In one embodiment, the server 250 can update the real scene model of the test bed based on the experimental data collected by the experimental data collection device 212 and the field environment data collected by the mobile terminal 230. For example, as the experiment progresses, the server 250 can update the different states of various devices, add the field environment data (e.g., images, videos, audio, temperature, noise, etc.) collected by the mobile terminal 230 to the corresponding elements in the real scene model. Accordingly, the updates to the real scene model can also be presented on the remote terminal 260. The server 250 can timely perform data processing and real scene model updating after receiving the experimental data and field environment data, so that the remote terminal 260 can timely (e.g., in real time or near real time) learn about the latest situation of the test bed experiment.

[0041] In one embodiment of the present application, the mobile terminal 230 can process the collected information, such as image recognition, noise removal, etc., and then send it to the server 250. When the user (e.g., a manager or an expert) of the remote terminal 260 needs to know the current real-time working condition, he or she can connect to the server 250 at any location (e.g., a monitoring room, the user's home) where communication is available to access the real scene model of the test bed. The user of the remote terminal 260 can further provide real-time guidance to the field staff through voice conversation via the server 250 or other communication networks, and the field staff can also interact with each other through voice recognition devices. For example, the remote user can provide operation instructions to the field operator via the remote terminal 260, which can instruct the field operator to adjust the experimental equipment, collect field environment data about a specified object using the mobile terminal 230, etc.

[0042] Figure 3 A schematic diagram of a multi-point collaboration work platform 300 of a test bed field interaction system according to one embodiment of the present application is shown. During the working process of an engine test bed, a test bed field multi-point collaboration work platform 300 can be built, which can be implemented using a server, a computer, a cloud service, etc. The multi-point collaboration work platform 300 provides a communication service function 310 and a multi-point shared interaction function 320.

[0043] For example, the communication service function 310 can implement audio transmission, video transmission, audio-video synchronization, etc. between the mobile terminal 230 and the server 250, experimental data transmission between the experimental data collection device 212 and the server 250, real scene model transmission between the server 250 and the remote terminal 260, etc. The communication service function 310 can also implement model processing of videos, audios, images, and use the model videos, audios, and images to update the real scene model of the test bed and transmit the updates to the remote terminal 260.

[0044] The multi-point sharing interactive function 320 can provide a shared collaboration area, so that each access user can add text, images, videos, shared files, models, etc. The multi-point sharing interactive function 320 can also allow each access user to add information on the real scene model of the test bench. The transmission of videos, audios, drawings, models, etc. involved can be real-time or near real-time, and each participant can simultaneously obtain the corresponding real scene information. The platform breaks the spatial distance between the original regions / areas and supports online multi-person operation.

[0045] Therefore, during the operation of the engine test bench, the on-site staff can interact and collaborate with the remote technical support team through their intelligent wearable systems in terms of videos, audios, images, drawings, models, etc. to communicate and solve problems occurring on site, realize multi-party parallel operation, improve efficiency, reduce the cost required for decision-making, and especially help solve problems in the early stage of failure.

[0046] In an embodiment of the present application, for the operation environment site that the operator needs to enter, the corresponding real scene model can be called to share on the multi-point collaboration work platform 300. After entering the real environment, the on-site operator can obtain the information of the real environment, such as the failure situation, noise, etc. through the mobile terminal 230, and the real environment information obtained by the mobile terminal 230 can be updated to the real scene model or can be selectively updated by the user. In addition, the remote user can initiate operation instructions or warnings and transmit them to the mobile terminal 230 through the multi-point collaboration work platform 300 to remind the on-site operator.

[0047] In an embodiment of the present application, as an example, for the problem occurring, the following operation steps can be adopted:

[0048] Step 1, the multi-point collaboration work platform 300 is established according to the specific problem. For example, the scene to be modeled (for example, the test bench scene) can be determined according to the work to be performed or the specific problem occurring, the on-site operator and the remote participant can be determined, and the corresponding support knowledge, files, data, technical requirements, etc. are prepared to establish the multi-point collaboration work platform 300.

[0049] Step 2, the remote participant enters the multi-point collaboration work platform 300. For example, the participant can click the ready button on the user interface to indicate that the preparation is complete.

[0050] Step 3, one or more on-site operators actually enter the work site. For example, the operator can carry or wear a mobile device to enter the test bench.

[0051] Step 4, the multi-point collaboration work platform 300 updates the live model according to the data received from the field devices and / or mobile devices. For different systems and devices in the work scene, technical support can be provided by respective professional persons in charge, and communication information is formed to make unified decisions (e.g., control instructions). For example, the professional person in charge at the remote terminal can analyze the video, audio, or other sensor data provided by the mobile terminal 230 (individually or as part of the live model) to convey control instructions to the field operator.

[0052] Step 5, the field operator completes the operation according to the decision and its corresponding technical requirements;

[0053] Step 6, the corresponding inspection confirmation, video transmission inspection process and results are performed;

[0054] Step 7, the operation is completed, the field operator and the remote participants exit the multi-point collaboration work platform 300, and the work is completed;

[0055] Step 8, the data in the multi-point collaboration work platform 300, such as the model, video, audio, sensor data, etc., are archived for subsequent use.

[0056] With the technology of the present application, the field staff can be seamlessly connected with the remote technical team, and the field operator's perspective can be shared with the entire team. Team members can efficiently analyze and discuss, make quick decisions, and improve overall efficiency.

[0057] Figure 4 A block diagram of a fuel control supply system 400 is shown in accordance with an embodiment of the present application. The fuel control supply system 400 provides fuel of a certain temperature to an engine to enable the engine to operate. The fuel supplied to the engine is maintained at a stable temperature and pressure, and if the temperature of the supplied fuel is too low, the engine can stall or fail to start due to not reaching the ignition point.

[0058] The fuel control supply system 400 can include numerous component parts, such as fuel supply / return lines, one or more boost pumps, one or more flow meters, fuel pressure regulating mechanisms, fuel temperature measuring devices, fuel pressure stabilizing tanks, outlet pressure regulating devices, fuel detection panels, etc. The fuel regulated by the components of the fuel control supply system 400 is provided to the engine as experimental fuel. Accordingly, the flow meters, pressure regulating mechanisms, fuel temperature measuring devices, etc. can be part of the experimental data acquisition devices, which can detect various fuel-related information (e.g., flow, pressure, temperature, etc.).

[0059] Figure 5A block diagram of an air control supply system 500 according to an embodiment of the present application is shown. The air control supply system 500 provides air to an engine so that fuel can be combusted sufficiently. The air control supply system 500 can include a plurality of components, such as air storage / supply lines, filters, pressurizing devices, warmers, temperature adjusting devices, pressure stabilizing devices, explosion-proof venting devices, air parameter measuring / control devices, etc. Respective experimental data collection devices (e.g., pressure gauges, temperature gauges, flow meters, etc.) can be included in the air control supply system 500, which can detect various air-related information (e.g., flow, pressure, temperature, etc.).

[0060] During normal operation of the air supply and fuel supply systems, parameters (e.g., air parameter information, fuel parameter information, etc.) in the systems can be detected by respective experimental data collection devices, and stored and / or processed. In addition, the parameter information can be transmitted to a server for record analysis. Once a fault occurs, a number of specialties can be involved, such as mechanics, circuitry, pneumatics, testing, computers, etc., and there are limited personnel on site at a test stand, which often cannot be equipped with the required technical personnel in time on site, and in order to efficiently solve the problem, it is desired that personnel of various specialties can be present at the same time to analyze and determine problems in the test process, such as temperature, pressure, flow, current, voltage, construction operation, work torque, etc., which is a common scenario encountered during engine testing.

[0061] According to an embodiment of the present application, a test stand worker can carry or wear a mobile terminal, and carry appropriate on-site detection tools and equipment, especially for checking at the time and location of a fault. On-site environmental data checked by the mobile terminal, such as image and / or audio data of experimental equipment of the test stand and / or the engine, image, audio, temperature, and / or humidity of the environment around the test stand, etc. can be transmitted to a server. The server can generate a real scene model of the test stand using configuration information of the test stand, and update the real scene model of the test stand based on experimental data collected by experimental data collection devices and on-site environmental data collected by the mobile terminal. The server can provide an access interface for personnel of various specialties to access the real scene model. Personnel of various specialties can even understand the actual problem occurring on site in the form of a perspective of an on-site operator of the test stand.

[0062] For example, in the air supply control area, due to system failure, the problem of air temperature cannot be adjusted occurs, the on-site operator needs to enter the area, check whether each device has an abnormality item by item, timely confirm that there is no problem to be excluded, and facilitate to find out the location of the problem. If there is no relevant professional person to join, the on-site problem judgment and solution are slow, for example, the checking result needs to be recorded, the checking result is sent to the corresponding professional person in the form of a photo, a text description and the like, and the judgment result of the professional person is waited for. After receiving the feedback of each professional person, the results are summarized and sorted, if the opinions are consistent, the next step is processed, if the opinions are inconsistent, further communication and coordination are needed, the problem solving process is too long, and it is time-consuming and laborious.

[0063] On the contrary, if the air supply control area has a problem, the real scene model of the air supply control area can be established by using the technology of the present application, each professional person can access the multi-point collaborative work platform to access the real scene model and obtain the on-site detection data of the on-site operator of the test bench. For example, taking a pneumatic valve as an example, it involves valve specialty (such as working torque, valve displacement), pneumatic specialty (such as air pipeline transmission pressure, temperature, flow), circuit specialty (such as feedback control current, voltage), computer specialty (such as computer control channel calculation output work instruction), test specialty (such as measurement of each related parameter). Therefore, participants of different specialties can timely analyze and judge, and can communicate with on-site personnel to obtain first-hand information on site. On this basis, each professional person makes analysis and judgment together, effectively avoids misjudgment caused by information difference between each specialty, and the evaluation result made is the result of many specialties such as on-site machinery, circuit, pneumatic, test and computer, which can command on-site personnel to perform correct operation. This decision-making scheme is fast and efficient.

[0064] The engine bench test test run process belongs to a complex system of multi-party participation test, and the problem encountered in the experiment generally needs to be solved after multi-party coordination. The multi-point collaborative work platform of the present application enables multiple remote users to obtain complete and unified on-site data in time, and to make decisions in time, which has great significance for efficient implementation of engine test experiment.

[0065] Figure 6 A flowchart of a test bench on-site interaction method 600 according to an embodiment of the present application is shown. The method can be implemented by a server, a computer, a cloud service and the like, or can be implemented by a single device or cooperatively implemented by multiple devices. For example, the server can include a processor and a memory, the processor is configured to execute the computer program in the memory to perform the method.

[0066] At step 602, a real scene model of the test bed can be generated based on configuration information of the test bed, which can include a model of an engine installed on the test bed and a model of experimental equipment of the test bed for engine experiment. The experimental equipment can include, for example, an engine stand, a fuel control supply system or a subsystem thereof, an air control supply system or a subsystem thereof, a monitoring alarm system, etc. In an embodiment, the real scene model can include a three-dimensional model or an animation model, and optionally include audio information.

[0067] At step 604, experimental data of the engine on the test bed can be received from experimental data collection equipment of the test bed. For example, the experimental data collection equipment can be connected to the experimental equipment and / or the engine of the test bed, and collect various data in the engine experiment. The field environment data collected by the mobile terminal can include, for example: fuel parameter information in the fuel control supply system of the test bed; air parameter information in the air control supply system of the test bed; running parameter information of the engine; etc.

[0068] At step 606, field environment data of the test bed can be received from the mobile terminal in the test bed. The field environment data collected by the mobile terminal can include one or more of: image and / or audio data of the experimental equipment and / or the engine of the test bed; or image, audio, temperature, and / or humidity, etc. of the environment around the test bed.

[0069] At step 608, the real scene model of the test bed can be updated based on the experimental data received from the experimental data collection equipment and the field environment data received from the mobile terminal.

[0070] At step 610, the real scene model of the test bed and the update of the real scene model can be presented.

[0071] At step 610, optionally, user input data can be received, and operation instructions based on the user input data can be provided to the mobile terminal.

[0072] Steps 604-612 can be executed cyclically until the engine test experiment ends.

[0073] The above describes the method and system for test bed field interaction according to the present application, which has one or more of the following advantages over the prior art:

[0074] 1. The mobile terminal of the field operator itself can have real-time interactive communication capability, so as to be seamlessly connected with the technical team, and the field operator's perspective can be shared to the entire support team. In a preferred embodiment, the mobile terminal can be a smart wearable device (for example, a head-mounted device), so as to free the operator's hands;
