Embodiment Construction

[0020] The technical state control process of the final assembly process is as follows: figure 1 As shown, it is divided into process document preparation stage, process document transfer stage, process document execution stage and final assembly process technology status acquisition stage.

[0021] Among them, the process document preparation stage includes two steps: the process document is compiled in the form of text description, and the association between "text description" and "process technology status" is realized; the process document transfer stage is to simultaneously transmit the process document and the association table to the MES system . The execution stage of process documents includes two steps: the operation and inspection personnel sign the process documents, and the signed information is automatically filled into the association table. The stage of obtaining the technical status of the final assembly process is to analyze and summarize the technical stat...

Abstract

The invention provides a method for controlling the status of a satellite assembly technology, which comprises the following steps of: leading text description of work step content in a technology file and satellite technology status to be in one-to-one correspondence by a globally unique identifier (GUID) when technological formation is performed, so that a contingency table is built; simultaneously leading the technology file and the contingency table into a manufacturing execution system (MES); automatically recoding signing information (such as an operator, a mutual examiner, an inspector, a signing time and the like) and an operation result into the contingency table if the text description and the technology status correspond to each other one by one when some general assembly operations are completed and the technology file is signed according to the text description and when the final assembly is implemented; and obtaining the real-time and comprehensive final assembly process engineering status by the classified summation and comprehensive analysis of data in the contingency table.

Description

technical field [0001] The invention relates to a control method for the technical state of the assembly process of complex products, which belongs to the category of digital design and manufacture. Background technique [0002] Satellite assembly is a complex system engineering, which runs through the whole process from the delivery of instruments and equipment for each subsystem to the delivery of qualified satellites for launch. According to statistics, the final assembly of a satellite includes more than 1,000 processes and more than 7,000 steps. During the implementation of the final assembly process, the technical status of the satellite final assembly process (such as whether the instrument is installed, whether the fastener is used for force measurement, whether the thermistor is pasted, whether its resistance value meets the requirements, etc.) is dynamically changing in real time, and the technical status is also complicated. Especially with the continuous increas...
