In order to avoid the interference of excessive human-computer interaction on workers and reduce the efficiency, the manual confirmation links are reduced as much as possible when the system is configured, and the working state of the station is judged by the state of the measuring facility on the station. If a data measurement is required for a process step, a breakpoint is set at that step, and if the measurement device is not enabled, that step is deemed not to have been reached. For example: if the station operator skips the measurement step N and executes the measurement step N +1 first, the system will send out an alarm (including a warning light, a buzzer and a process display board) to inform the station operator that the step missing occurs in the processing process and the station operator needs to re-check. Similarly, if the measured data does not satisfy the qualified range while the measuring step is being performed, the system will issue an alarm to inform that the step has not yet reached the requirement and the processing is to be continued.

Specifically, the process file adopts a standardized data format, and comprises an assembly task name, a station position, an assembly process name, detailed steps, values required to be checked in each step and a qualified range of measured values.
The intelligent acquisition terminal of the embodiment of the invention supports the networking of interconnection of heterogeneous equipment, serves an industrial internet solution at an assembly site, and forms an error-prone process execution condition acquisition network topological structure which influences the assembly quality, and the topological structure has the characteristics of uniform access, platform independence, fault tolerance, redundancy, easy expansion, low cost, standard safety model and the like.

The intelligent acquisition terminal of the invention can be used on line through the steps of user right distribution, new process file creation, process file overview, process file determination, process configuration determination and the like, and the detailed description is as follows:
the method comprises the following steps: and (4) logging in by the user. The embedded software is designed with a user login system, firstly, a user must use a legal user name and a correct password to log in the system (as shown in fig. 4), the configuration system is allowed to be used only when the user logs in successfully, and the authorities owned by the users with different grades are also different, so that the user can be ensured to exercise the authority within a certain authority, and the safety of the system is ensured. According to different user authorities, different configurations are carried out on intelligent acquisition terminal software, field production personnel with lower authorities only have the authority of selecting the existing process files for production, and process personnel have the authority of creating new process files. The process file writing format of the program can be designed according to the content of the existing paper process file, and information such as a timestamp for tracing the source is supplemented.
Step two: and (5) process file overview. As shown in fig. 6, the user can make an overview of the process files currently stored in the terminal database, and the displayed information includes: data number, company name, workshop, product name, product number, part name, part number, author, creation time, modifier, last modification time. And the function of screening according to the data number, the workshop number, the product name, the product number, the part name and the part number is provided for the user, so that the user can conveniently find the correct process file in a complicated process file library.
Step three: and (4) selecting a process file. And 5a and 5b, selecting process files, and displaying relevant process information to a user on a preview interface (such as fig. 6) for the process files selected by the user to reduce the influence of misoperation of the user, wherein the user checks basic information of process data, a complete part list, a process list, a step list and a process part list in the process, and if errors are found or tool preparation is not sufficient, the user needs to start working after the preparation of materials required by the machining link is finished or return to the previous step to reselect the required process files.
Step four: and generating the autonomous configuration. When the preparation work of production and processing is finished, the user can select the immediate effect key, and the algorithm program can use the process file to carry out autonomous configuration on data acquisition and operation process control so as to adapt to production. The first step in the validation of the process file would require the user to provide the product number as a record index. The product can be numbered by using a bar code or a two-dimensional code, and the product number is automatically acquired by using a code scanning gun (as shown in figure 7), so that manual error input is avoided. According to the process file, the background autonomic configuration algorithm will call the process information in the process database to configure the background detection program and the monitoring interface (as shown in fig. 8).
Step five: a new process file is created (as shown in fig. 9a, 9b, 9c, 9d, 9 e). When the craftsman chooses to create a new process file, the system will initiate the create process file program. Firstly, basic information of the process file is required to be created, wherein the basic information comprises a data number, a unit, a workshop, a product number, a product name, a part number and a part name. The added data number is the same as the existing process file in the library, so that the process file cannot be created. Like the existing paper process file, the process file is created by allowing a craftsman to add a complete part list so that a manufacturer can check and check required spare and accessory parts before starting processing after selecting the process file, thereby avoiding production interruption caused by finding out that the spare and accessory parts are lacking in the process of processing. When adding the process, the process personnel is allowed to add parts required by the process, and the process step information required by the process is added, and the process step information comprises the following steps: step number, step name, process content, detection items, detection parameters and the like. And after the configuration is finished, entering a preview interface, and summarizing the added process at the interface by a technician, wherein if the added process is in line with expectation, the relevant data is stored in a database, and otherwise, the previous steps can be returned for modification. And finally, repeating the steps from two to four.
In conclusion, the industrial field interconnection protocol conforming to the OPC-UA protocol is integrated, and the blank of the requirement of the autonomous acquisition equipment between the aviation digital workshop system and the bottom-layer quality control equipment of the assembly station is filled.
The invention successfully develops the intelligent acquisition terminal for the aviation product assembly line, supports four installation modes, and meets different installation requirements of special structures and special environments of assembly stations.
