First, has the paper recording instrument
Remembered I in 70, the 80's surveys temperature am use
the ratio-meter, the domestically produced moving coil measuring
appliance, the manual record hotly controls the data, afterwards air
operated used a Shanghai automation measuring appliance factory
production, electrically operated has the paper recording instrument,
every day as soon as went to work the tour inspection to install the
rolled paper to the recording instrument to add, the blue ink red, in
the ink bottle inserts the root soft plastic tube to link the
indicator to draw a line, in the hand red blue was very uncomfortable,
afterwards designed contains the ink the recorder pan. Some 2,
4, 6 channels, the recording paper archive, the overall expense is
high.
Second, non- paper recording instrument
The near ten year computers software technology
development appeared the plate to install the non- paper recording
instrument, in recent years developed, the application swiftly and
violently widespread, the function formidable, the electric power
profession application are very many. If Zhejiang major and
medium controls, Beijing beautifully reaches and so on the unit has 4,
6, 8, 16, 24, 48 and so on the channel installs on the gauge board the
performance is stable. But has point of all signals electric
cables to have to connect on the gauge board, the application
situation has the limitation.
Third, main line non- paper recording instrument
Along with computer hardware, software technology
development configuration software promotion, communication agreement
standard making, RS485 communication main line application.
Touches the screen plate computer the appearance, caused the
system overhead construction to appear the diversification.
The recent generation of communication main line form non- paper
recording instrument appears. Because touches the screen plate
computer development very fast, the hardware merchant careful design
inserts the type hardware technology, Microsoft's WINCE operating
system, the richly colorful liquid crystal touches the screen, the
system itself reliability obtains the guarantee, fast constitutes the
high performance the man-machine contact surface.
The operating system uses WINCE, the installment inserts the
type configuration software package, the freedom edits the
configuration software realization application function.
Technical process disposition and tendency chart, good chart,
report form, historic record and so on
The system may charged pull out inserts, does not have
the hard disk, the anti- vibration, the system cannot dying machine,
enhances the automated system the stability.
Because uses the newest liquid crystal, touches the technology,
the product scale greatly enhances. The system relies on its
formidable ethernet communication function, the complex curve
function, the image artistic man-machine contact surface and each kind
of report form function obtain the widespread application. If
the Xiamen space electricity AI-2000W field bus non- paper recording
instrument, has succeeded application in electric stove, chemical
fiber, hospital air-conditioning system. Serves as the terminal
demonstration manipulator (on position machine). Next hangs 2,
4, 8, 16, 32, 64, 100 display controls measuring appliance, the
gathering module.
A main line connection disperser installment lower position
machine - AI display control measuring appliance - gathering module,
considerably measures the control demonstration probe temperature, the
pressure, the current capacity in the scene. Realization
simulation quantity, switch quantity, input, output.
Saved in the implementation process has installed the electric
cable cost, the wiring conveniently, installment space small, the
application scope was broad. Your firm website has the detailed
introduction
Above states each kind of product to have it own
vitality, respectively has each use, only this provides the design
idea. The article originates from:
