High-performance signal adapter plate

Abstract

The invention discloses a high-performance signal adapter plate, which is arranged between a signal circuit to be acquired and joints HD-68 of a data acquisition card and used for transmitting acquired signals to the data acquisition card. The high-performance signal adapter plate comprises a PCB (Printed Circuit Board) (1) and a panel (2) covering the PCB, wherein the PCB comprises a first wiring layer (101), a signal ground layer (102), a system ground layer (103) and a second wiring layer (104) which are stacked in sequence, a plurality of Lemo sockets (11) are distributed on the first wiring layer (101) to serve as signal input ports, and the joints HD-68 (14) are distributed on the second wiring layer (104) and are respectively connected with each Lemo socket (11) correspondingly. According to the invention, the pins HD-68 of the data acquisition card are grouped based on signals, the signals are accessed to the Lemo sockets at the input ends through Lemo plugs, and thus, the signal wiring is very attractive. The Lemo socket has a favorable plugging mechanical performance, not only facilitates the management and access of signals but also is favorable for increasing the anti-jamming capacity of a channel.

Description

technical field [0001] The invention relates to a signal adapter board, in particular to an adapter board used in a data acquisition system with HD-68 (High Density 68-pin) high-density joints to connect input signals and data acquisition cards. Background technique [0002] Data acquisition (DAQ) refers to automatically collecting non-electrical or electrical signals from sensors and other analog and digital units to be measured, and sending them to the host computer for analysis and processing. The data acquisition card is a computer expansion card that realizes the data acquisition (DAQ) function. At present, among the mainstream high-performance data acquisition cards in the market and the acquisition card interface technology in many professional applications, the Small Computer System Interface (SCSI, Small Computer System Interface) occupies a dominant position. SCSI is a special bus structure, which can dynamically divide and operate multiple devices in the computer...
