Embodiment Construction

[0022] Principle of the present invention will be further described below in conjunction with accompanying drawing:

[0023] Refer to attached figure 1 , is a structural block diagram of the present invention. In the figure, 1 is an external interface chip, 2 is a hardware interface, 3 is a driver program, 5 is a virtual digital display application program, 4 is a calling interface module, 6 is a data recording module, 7 is a display module, 8 is a data processing module, 9 is the setting module. In the external interface chip 1, the firmware program receives the data request from the host and starts to read in the measurement data of the grating sensor; after a set of data is read in, the data is packaged and sent to the host through the hardware interface 2, waiting for the next data from the host ask. The host end receives the packaged data sent by the firmware program by the driver program 3 . The data processing module 8 obtains the data packet from the driver 3 for d...

Abstract

A grating virtual data display system with multichannel is featured as realizing process and result display for output data of grating displacement transducer (GDT) based on computer; sending signal of multipath GDT computer and to let virtual display application program obtain data for carrying out data process result storage and display output, and providing function interface for external program in order to let it call constitutional observe and control system.

Description

technical field [0001] The invention belongs to the field of digital display and virtual instruments of grating displacement sensors, and in particular relates to a convenient and practical multi-channel grating virtual digital display system. Background technique [0002] The grating digital display is one of the important components of the grating measurement system. In the grating measurement system, the grating digital display is used to display the measured results of the grating ruler. Whether the grating digital display is convenient, practical, and has reasonable functions directly affects the use of measurement. [0003] However, the traditional grating digital display has problems such as complex structure, low integration, single function, inability to upgrade and expand, difficult to interface with other devices, difficult to control and record data, and poor flexibility. Today, computer-based processing systems and measurement systems have gradually become the...
