A small data recording device and assembly method based on stack design

Abstract

The invention discloses a small-sized data recording device and an assembly method based on a laminate design, which is characterized in that it includes a communication board layer (base layer), a processor board layer, an input board layer (intermediate layer) and a filter board layer connected in sequence. Each functional layer of the board layer (top layer); guide pin A and guide pin B are guided during the stacking process inside the middle layer and between the functional layers to ensure accurate positioning and guidance of the layers during the blind insertion process. The present invention can not only complete the data storage function of the current data recorder, but also provide a layer-based design for the miniaturization requirements of the product, in which each functional layer is designed to be stacked with each other, and has the advantages of small cross-sectional size of the product, stacked installation of each functional layer, and blind insertion operation With the characteristics of good reliability and good test and maintenance performance, it realizes data recording equipment based on module miniaturization. It also has 1553B interface, information exchange interface and software online upgrade interface, providing a more comprehensive solution for data recording equipment.

Description

technical field [0001] The invention belongs to the field of electronic engineering and mechanical design, and in particular relates to a small-scale data recording device and assembly method based on laminate design, which is mainly used for device command transmission and information interaction data storage, and is especially suitable for key parameter recording of aircraft products . Background technique [0002] The traditional data recorder is referred to as "black box", which is widely used in aircraft, vehicles, ships and other equipment to record information such as the voice environment and performance parameters of products in the application field. According to the recorded information data, it can be sent to Incorporate a simulator that can analyze the scene environment at that time. [0003] The traditional information recorder intelligently accepts information data during the working process, does not have the mutual exchange of data and the issuance of contr...

AI Technical Summary

Problems solved by technology

[0003] The traditional information recorder intelligently accepts information data during the working process, does not have the mutual exchange of data and the issuance of control instructions, cannot return real-time data to the corresponding equipment, has no data analysis and processing functions, and cannot perform software upgrades on products, etc. In particular, the miniaturization design of the product has not taken sufficient measures to apply to small aircraft equipment
