Description

The invention relates to a device assembly for operating at least one test adapter used in a manufacturing plant for the electrical functional testing of test objects, in particular for the electrical functional testing of devices or device components manufactured in the manufacturing plant, wherein the test adapter comprises a housing and at least one test contact unit arranged in the housing for contacting at least one test object contact during a test sequence, and a line arranged in the housing from the at least one test contact unit to a connection provided on the housing, at least one sensor arranged on or in the test adapter, and a data acquisition unit for acquiring values from the sensor, wherein the test adapter is associated with an operating data memory which acquires the values of the at least one sensor acquired by the data acquisition unit and determines at least one operating status piece of information from this, wherein the at least one operating status piece of information is read from the operating data memory of the test adapter by means of a service device that can be wirelessly coupled to the test adapter and stored by the service device in a service device memory, such that the service device transmits the operating status information stored in the service device memory to an external data processing unit via a data transmission network. which stores the operating status information in a data room. The advantage of the solution according to the invention is that the operating data storage in the test adapter is limited with regard to the operating state information to be stored and can therefore only store and evaluate a small volume of operating state information, while the data space of the external data processing unit offers a large number of storage and evaluation options. Furthermore, such a test adapter is often located in a manufacturing area where there is no access to a generally usable data transmission network, for example, no internet access. For this reason, the solution according to the invention provides that the operating status information is read from a service device and stored in a service device memory, and that the service device is able at another time and place to transmit the operating status information stored in the service device memory via a transmission network, for example the Internet, to an external data processing unit, which then stores the operating status information in a data room. This solution also has the advantage that the user of the service device is simultaneously enabled to analyze the operating status information stored in the service device's memory. Such a service device is usually available to a service employee or an employee responsible for the manufacturing operation, in order to enable them to intervene if necessary in the event of malfunctions. Since a sufficiently large data space can be provided to the external data processing unit, an advantageous solution provides that the external data processing unit evaluates the transmitted operational status information in addition to storing it. Such an evaluation process can take place in many different ways. One advantageous solution involves the external data processing unit evaluating the operational status information by comparing it with reference data. Such reference data can be older data from the same test adapter, or the reference data can be data from test adapters of the same type. Such evaluations can be geared towards a wide variety of results. One possibility is that the external data processing unit, as a result of the evaluation, predicts maintenance or future maintenance cycles of the respective test adapter. This does not contradict the fact that the test adapter itself can detect and display short-term maintenance needs; however, predicting future maintenance requires a far more complex evaluation process, particularly using data over a longer period than can be stored in the test adapter, and possibly also using data from comparable test adapters of the same type, which are also collected over a longer period. Furthermore, there is the possibility that the external data processing unit will be added to the program suggests replacement parts for the notified maintenance of the respective test adapter. Another possibility is that the external data processing unit presents instructions for maintenance, for example in the form of drawings, in particular exact drawings of the components of the test adapter and/or exploded views of the test adapter and/or instructions, for example video instructions, for carrying out the maintenance. In order to obtain the most comprehensive data set possible for the respective test adapter, it is particularly advantageous if the external data processing unit creates a complete documentation of the test adapter from the operating status information and/or the evaluations carried out and, in particular, saves this in the data space.
