Abstract

The utility model provides an acquisition card with a modularized structure, which comprises an acquisition substrate and acquisition tower plates, and is characterized in that the acquisition card of the modularized structure is formed by the acquisition substrate (21) and two groups of fixing parts (1, 2, 3, 4, 7, 8, 9 and 10) with pluggable openings which are fixed on two acquisition tower plates (22 and 23) of the acquisition substrate (21); the acquisition substrate (21) is provided with two data communication ports (5 and 11) and integrated with a PCI bridge chip (13), an embedded processor (15) and an FPGA chip (14); the two acquisition tower plate (22 and 23) are formed by a data acquisition module and a special data communication and control port; and the two acquisition tower plates are respectively communicated with the acquisition substrate through ports (5 and 6) and ports (11 and 12). The acquisition card with the modularized structure has simple structure and low cost, is easy to be expanded, and lowers failure rate.

Description

A kind of capture card of modular construction

Technical field

The utility model relates to a kind of capture card, particularly a kind of capture card of modular construction of built-in field.

Background technology

In the various industries of commercial production and scientific research, often utilize capture card that high speed analog signal, low speed simulating signal, digital signal, fiber-optic signal are gathered.Capture card commonly used now all adopts integrated structure design, on an integrated circuit board, realize data acquisition and Data Control function, though integrated level is higher, but complex structure, design cost height, extendability and versatility difference and data-handling efficiency are not high, and these shortcomings can not adapt to current built-in field client's demand.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art and capture card that a kind of modular construction is provided, and the capture card of this modular construction is simple in structure, cost of development is low, extendability is strong, be easy to safeguard, can reduce the risk of product development.

The technical scheme that the utility model adopted is: the capture card of modular construction, comprise and gather substrate and gather column plate, but the capture card of described modular construction is by a described collection substrate be fixed on the described collection substrate two by two groups of fixtures with plug-and-pull port and gather column plates and form;

Described collection substrate has two data communication ports and is integrated with pci bridge chip and flush bonding processor and fpga chip;

Two blocks of described collection column plates by data acquisition module and and the data communication mouth, a control mouthful compatible data communication mouth, control of gathering substrate mouthful forms, two blocks of described collection column plates are realized by two group interfaces respectively and the communicating by letter of collection substrate.

But should constitute by a collection substrate and two blocks of collection column plates that are fixed on the collection substrate by fixture based on the capture card of modular construction with plug-and-pull port; Gather substrate and have two controls mouthful, and integrated pci bridge chip, flush bonding processor, fpga chip; The collection column plate also has the data communication mouth of special use and control mouth to communicate with the collection substrate except being integrated with the data channel that can gather high speed analog signal, low speed simulating signal, digital signal, fiber-optic signal.

Therefore, the modular construction capture card of the utility model employing is simple in structure, cost is low; Adopt pci bridge chip to intercom mutually, can change at any time, can gather polytype signal, broken away from the shortcoming of traditional integral structure capture card extendability difference but be fixed on the collection column plate of gathering on the substrate by fixture with plug-and-pull port with host computer; And the data processing method of the combination of flush bonding processor and fpga chip on the substrate has improved data processing efficiency.

Fig. 1 is a plane structure chart of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is described in more detail.

As shown in Figure 1, gather column plate 22,23 by data acquisition module and and gather the data communication mouth 5,11 of substrate 21, the data communication mouth of control mouthful 6,12 compatibilities, control mouthful composition, but the collection substrate 21 of modular construction capture card is fixed first data acquisition column plate 22 by first group of fixture 1,2,3,4 with plug-and-pull port, and the fpga chip of gathering on the substrate 21 14 is gathered communicating by letter between the column plate 22 by a data communication mouth 5 and control mouthful 6 realizations with first; But gather substrate 21 and fix second data acquisition column plate 23 by second group of fixture 7,8,9,10 with plug-and-pull port, the fpga chip of gathering on the substrate 21 14 is gathered communicating by letter between the column plate 23 by a data communication mouth 11 and control mouthful 12 realizations with second.Having the fixture that can plug interface by above two groups can carry the collection column plate with different acquisition interface and form different capture cards gathering on the substrate.Host computer can send order to the modular construction capture card by the pci bridge chip on the capture card 13, also can monitor by the duty of 13 pairs of modular construction capture cards of pci bridge chip, after the modular construction capture card is started working, the data that collect are by gathering the data communication mouth 5 on the substrate 21,11 are transferred to fpga chip l4,14 pairs of different types of data of fpga chip are packed and pre-service, fpga chip 14 sends to flush bonding processor 15 to data then, after flush bonding processor 15 is finished data processing, again data are sent to fpga chip 14.Last fpga chip 14 sends to host computer or other integrated circuit boards to data by interface 16,17,18,19,20.

The capture card of modular construction is simple in structure, cost is low, and is easy to expand acquisition function and has improved data-handling efficiency.
