Definitions
- Apparatus and method for remote access to at least one test environment by at least one user application
- the application relates to a device and a method for remote access to at least one test environment by at least one user application.
- Test environments are used, for example, in the development of control units, such as those used in the automotive or aviation industries to control technical systems such as engines or brakes.
- the development of control units has become a highly complex process. New control and regulation functions for control units should be tested as early as possible in the development process in order to check functionality and determine the further direction of development. In the more advanced development process, it is important to test the already well-developed control unit as comprehensively as possible.
- Test environments can offer the possibility of testing such a system to be tested using an environment model.
- a system to be tested can have both functions, e.g. software, and devices, e.g. hardware, which can be tested in the test environment.
- the environment model simulates the respective environment through suitable data exchange for the software or hardware.
- the test environments can have an interface to a user who can use the test environments to carry out experiments with the system to be tested. Experiments can be used to set parameters for the simulations with the system to be tested and the environment model, and values that occur in the simulation can be displayed and recorded.
- a device for remote access to at least one test environment by at least one user application is provided as a device via a communication network available computer resource.
- the computer resource has an experiment manager and at least one measurement instance.
- the experiment manager provides the at least one user application with a first login interface for logging in via the communication network.
- the experiment manager provides the at least one test environment with a second login interface for logging in, in particular via the communication network.
- the second login interface provides for logging in the at least one test environment via a software agent.
- the at least one measuring instance has a control interface for the at least one user application and a measurement interface for the at least one test environment. It is intended to transmit display data to the at least one user application via the control interface and to receive control data for the test environment from the at least one user application, e.g. for a measurement and/or simulation running in the test environment. It is intended to transmit the control data to the at least one test environment via the measurement interface and to receive measurement data for generating the display data from the at least one test environment, so that remote access to the at least one test environment is possible for the at least one user application.
- the device enables at least one user at any location to gain remote access to at least one test environment via a communications network and a computer resource available therewith.
- Several users can also work on the same test environment simultaneously via remote access via the communications network. The device makes this remote access technically reliable and easy to implement.
- test environment Since the test environment registers itself with the computer resource and in particular with the experiment manager through a software agent, its At least no human intervention is required in the test environment to enable remote access.
- computer resource for remote access to the test environment or to multiple test environments enables different users to access the same test environment or different test environments simultaneously.
- Using the computer resource also makes it possible for the respective test environment to be available globally for remote access.
- remote access means that a user application that is present at a first location can access a test environment that is present at a second location. This makes it possible to overcome large distances, such as several hundred kilometers or several thousand kilometers, between the first and second locations, thus enabling global access distributed across the globe.
- the at least one test environment provides a technical device, either in terms of software or hardware, that tests a system under test with regard to its functionality and thus carries out measurements.
- a technical device either in terms of software or hardware
- HIL hardware-in-the-loop simulators
- SIL software-in-the-loop simulators
- a hardware-in-the-loop simulator for example, devices to be tested, such as control units that are used in a vehicle to control a system, for example an engine, can be tested with regard to many possible situations.
- software-in-the-loop simulator software, e.g. functions that are available as software code, can be tested, e.g. in interaction with a simulated environment.
- test drives for example.
- a test environment enables the testing of a large number of situations that may later arise during use. Since companies using such test environments have users in different countries, such remote access is particularly advantageous according to this application in order to be able to access the test environment regardless of the location where the users are located, whereby the test environment can be set up and operated at a different location.
- the user application is intended to provide the user, who uses the test environment, with access to the test environment.
- the user application can, for example, have a graphical user interface to enable the user to interact.
- the user application can, for example, be browser-based software with which measurement data from the test environment can be graphically displayed and further analyzed, and the user application generates control data based on the user's input that influences the simulation and/or measurement in the test environment.
- browser-based software other implementations of the user application are also possible, e.g. through an app.
- the communication network can be, for example, the Internet, but also, alternatively or additionally, a company's global communication network.
- the computer resource can be understood as a so-called cloud solution, which is maintained, for example, by the company itself that uses the test environment and the user application or by a service provider that then offers so-called hosting of the computer resource.
- the computer resource has an experiment manager, which is designed as a software module, for example, and provides a first login interface for the user application to log in via the communication network.
- the experiment manager also has a second login interface for the test environment so that the test environment can log in via a software agent as described.
- Software and communication technologies that are common on the Internet, for example, are used for the login interfaces.
- a software agent is a computer program that behaves independently and dynamically within a given framework. This means that a certain processing procedure runs depending on various conditions without an additional start signal being given from outside or without external control intervention during the process. In this case, this enables the test environment to log in to the Experiment Manager via the second login interface. If the test environment is therefore put into operation, this test environment can then log in directly to the Experiment Manager via the software agent. it is available for remote access to the user applications. It is possible for different test environments to log in to the Experiment Manager in order to be available for remote access. Accordingly, many users can log in to the Experiment Manager via their user application, but this is initiated by the user himself, while the respective software agent ensures automatic login to the Experiment Manager for the respective test environment.
- the first login interface is therefore a software module of the Experiment Manager, as is the second login interface.
- the computer resource also has a measuring instance, which can also be designed as a software module.
- the measuring instance has a control interface for the at least one user application and a measuring interface for the at least one test environment.
- the control interface transmits display data to the at least one user application, while the user application transmits control data for the test environment, e.g. for a measurement and/or simulation, to the measuring instance via the control interface.
- the measuring interface ensures that the control data is transmitted to the at least one test environment and that measurement data for generating the display data is received from the at least one test environment. This enables remote access from the user application to the test environment via the computer resource.
- the aforementioned data can be transmitted in packet-oriented form, i.e. there does not have to be a complete or continuous communication channel from the user application to the test environment, which facilitates remote access from several user applications to a test environment or to different test environments.
- test manager When registering the test environment, it is planned to send information about the test environment to the experiment manager as configuration data. This means that the experiment manager knows what can be tested in the test environment and how, and also, for example, what type of simulator the test environment has.
- the at least one measuring instance is set up to process the measurement data for generating the display data depending on display configuration data.
- the measurement data for generating the display data are thus processed according to the requirements of the User applications are processed.
- Access to the measurement instance can be established, for example, via the experiment manager.
- a measurement instance can be set up to communicate with several user applications and/or several test environments and, in particular, to process their data.
- the at least one measuring instance is set up to process the control data before transmission to the at least one test environment depending on the configuration data. This allows the control data to be adapted to the configuration of the test environment.
- the test environment can then use this processed control data immediately during testing and/or in the simulation and/or in the measurement.
- the measuring instance can communicate with several test environments and process and transmit the control data using the configuration data adapted to the respective test environment.
- the computer resource has a database that is intended for storing information on the registrations, the control data, the measurement data, the configuration data and/or the display configuration data, with the storage being provided in particular by the experiment manager.
- This storage then makes it possible to trace the processes through remote access. For example, if a communication error occurs, remote access can be reestablished using this stored data.
- the experiment manager is particularly suitable for storing this data as an instance that controls the storage.
- the database can be used to enable data exchange of shared data within the computer resource.
- the computer resource is intended to have a post-processing service that is set up to record and manage the measurement data and to provide access to the measurement data. This measure also enables access to such measurement data at a later date, particularly in the event of communication errors, but also in order to re-understand things from the past.
- the database and/or another memory is provided for storing the measurement data.
- the database and the other memory can also be embodied in a common memory.
- the at least one measurement instance has a control interface for the at least one user application and a measurement interface for the at least one test environment
- the at least one measuring instance transmits display data to the at least one user application and receives control data for the test environment, in particular a simulation and/or measurement running thereon, from the at least one user application, wherein the at least one measuring instance transmits the control data to the at least one test environment and receives measurement data for generating the display data from the at least one test environment,
- the method offers the advantage that at least one user at any location can obtain remote access to at least one test environment via a communications network and a computer resource available therewith. This leads to great flexibility as to where the users or the test environment can be located.
- the use of the computer resource for remote access to the test environment or to several test environments enables different users can access the same test environment or different test environments at the same time.
- By using the computer resource it is also possible for the respective test environment to be available globally for remote access.
- the test environment transmits information about the test environment to the experiment manager as configuration data in connection with the registration. This means that the experiment manager knows what can be tested about the test environment and how.
- the at least one measurement instance can process the measurement data for generating the display data depending on display configuration data.
- the measurement data for generating the display data is thus processed according to the requirements of the user applications. This enables adaptation to the display options on the respective user application.
- the at least one measuring instance can process the control data before transmission to the at least one test environment depending on the configuration data. This enables the control data to be adapted to the conditions in the respective test environment.
- the experiment manager can store information about the registrations, the control data, the measurement data, the configuration data and/or the display configuration data in a database.
- a post-processing service can be provided which records, manages and/or grants access to the measurement data in a process step.

- the display data is designed in such a way that it is suitable for graphical representation in the user application and also for further analysis by the user. For example, the user can further process the display data using mathematical methods in order to gain further insights.
- the control data instructs the test environment, for example, to test the device to be tested in certain parameter ranges. device. Therefore, the test environment is set up to communicate with the device, to test the system to be tested, e.g. hardware and/or software, and to generate the measurement data, wherein the measurement data depends on the system to be tested, e.g. the hardware and/or the software.
- a system which comprises a previously described device, a previously described user application and a previously described test environment.
