A conversion device for a data acquisition system

Abstract

The invention discloses a conversion device of a data acquisition system. The conversion device at least comprises a dual-layer wiring terminal, a rectangular connector DB37 and a rectangular connector DB78, wherein the dual-layer wiring terminal is provided with 38 wiring ports, the 16 wiring ports are defined as positive wire interfaces, the 16 wiring ports are defined as negative wire interfaces (each positive wire interface and each negative wire interface correspondingly form an input interface), the rest wiring ports are standby and structure ground interfaces, and an individual tested signal is input from an element; the dual-layer wiring terminal and the rectangular connector DB37 are connected in series through connecting wire penetration holes; the rectangular connector DB37 and the rectangular connector DB78 are connected in series through connecting wires and resistors. According to the conversion device, the problems of small range of an input channel, limited wiring mode and the like in data acquisition equipment are solved and the data acquisition equipment is effectively optimized; the conversion device has the long-term application value.

Description

technical field [0001] The invention relates to the field of conversion devices, in particular to a conversion device of a data acquisition system. Background technique [0002] In the ground test of aviation products, data acquisition equipment is one of the important equipment for real-time acquisition of some parameters of the product (such as analog quantities), which can monitor and judge the working status of system components and assist in rapid fault location. At present, the commonly used data acquisition equipment in the market is mainly designed based on general-purpose test requirements. The voltage signal conditioning card has a small input range (±10V), multiple channels (16Ch / board), and various interface forms (such as BNC, banana socket and rectangular Connectors, etc.), making it impossible to collect large voltage signals, and the manufacturing process of the corresponding test adapter cables is complicated, which affects the development of the test work, ...
