Abstract
A data selection display device of two measuring instruments comprises input cards, display modules, a selection on-off block and an order control block, and is characterized in that two input cards are arranged and are respectively connected with two display modules, the two display modules are respectively connected with the selection switch block, the selection switch block is further connected with a main display block, the selection switch block is further provided with manual selection gears SW1 and SW3 and an automatic gear SM2, when the SW1 gear is selected, an interface S11 of the selection switch block is communicated, when the SW3 is selected, the interface S13 of the selection switch block is communicated, when a SW2 is arranged, and an interface S12 of the selection switch block is communicated with the order control block. Compared with traditional total distributed control system, only data of one of a plurality of instruments can be displayed in the display device, and other devices are used for standby. Thereby DCS configuration can be well optimized, images can be definite and clear, the operation is simple, error operation of operation staffs can be reduced, and production operation and safety accidents can be greatly lowered and avoided.
Description
Technical field
The utility model relates to instrument and meter and automatic control system, relates in particular to gage data and shows the opertaing device of selecting switching.
Background technology
In industrial processes, the measurement parameter of some measuring equipment is to the production operation particular importance, in case instrumented data is wrong or the measuring equipment damage will cause production is caused significant impact and security incident, in this case, for guaranteeing production safety, stable, long-term operation,, 2 or 3 identical measurement instrument equipment are installed often at same measurement point, there is one to go wrong, also can not influence control and safety in the production.
Traditionally, generally signal is directly delivered to Distributed Control System (DCS) DCS demonstration and control, there are several just to show several data, the data volume that meeting like this (1) causes operating personnel to monitor strengthens, scatter operation personnel's energy, cause absent minded, easily maloperation; (2) technological process of production complexity, picture is many and unintelligible, in disorder easily, and (3) DCS configuration is not optimized, and influences system running speed.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of two gage data simple in structure, practical, that optimize to select display device.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of two gage data are selected display device, comprise input card, display module, selector switch piece and sequential control piece, it is characterized in that described input card is two, join with two display modules respectively, two display modules join with the selector switch piece respectively, the selector switch piece also joins with main display module, and manual selection shelves SW1, SW3 and automatic transmission SW2 are arranged on the selector switch piece; When selecting the SW1 shelves, the interface S11 of selector switch piece connects; , when selecting SW3, the interface S13 of selector switch piece connects; When being changed to SW2, the interface S12 of selector switch piece connects the sequential control piece.
As improvement of the present utility model, described selector switch piece increases and connects a timer, when being changed to the SW2 shelves, starts timer.
In industrial parameter measurement for some visual plants, as parameters such as pressure, temperature, thing position, flow, vibration, displacements, need with measurement zone 2 identical instrument measurement equipment be installed at same measurement point, the current and voltage signals of the standard of its equipment output is 4-20mA.DC and 1-5V.DC, this standard signal is sent into Distributed Control System (DCS) DCS, and requirement main display module on DCS only shows the data that one of them is correct.The selector switch piece is the DCS inner function module, selector switch has 2 road input signal channels and 1 road output signal channel, when work, have only 1 road input signal channel and 1 road output signal channel to connect, and another road input channel is under an embargo, and two input signal channels of selector switch piece do not have the switching of interruption in the process of switching; When being changed to the SW2 shelves, the selector switch piece is connected the sequential control piece, standard signal is handled through the input of DCS, DCS handles through the sequential control piece and judges whether signal has taken place unusually automatically, when having, one of them that detects measurement parameter report to the police and wrong the generation, as line short, open circuit or load module when any one problem such as fault alarm is arranged, sequential control piece control selector switch piece, according to the normal and abnormal conditions of measurement data, on DCS, automatically switch and select to show one of them correct measurement data; When being changed to the SW1 shelves or being changed to the SW3 shelves, then be to implement manually to select.
According to principle of the present utility model, improve a little, can realize that more gage data show the control of selecting switching.
The utility model shows with traditional Distributed Control System (DCS) DCS to be compared with control, and many instrument only show one data wherein, and other equipment is as standby.So optimized the DCS configuration well, picture is clear clean, simple to operate, has reduced operating personnel's maloperation, reduces greatly and has avoided production operation and security incident.
Description of drawings
Below in conjunction with description of drawings and embodiment the utility model is described in further detail.

Accompanying drawing 2 is the improved block diagram of the utility model
In the accompanying drawing: 1 is the first input card, and 2 is the first display module, and 3 is the selector switch piece, and 4 is main display module, and 5 are the sequential control piece, and 6 is timer, and 7 is the second input card, and 8 is the second display module.
Embodiment
Embodiment of the present utility model:
Embodiment of the present utility model:
A kind of two gage data are selected display device, comprise input card, display module, selector switch piece and sequential control piece, it is characterized in that described input card 1,7 is two, join with two display modules 2,8 respectively, two display modules 2,8 join with selector switch piece 3 respectively, selector switch piece 3 also joins with main display module 4, and manual selection shelves SW1, SW3 and automatic transmission SW2 are arranged on the selector switch piece 3; When selecting the SW1 shelves, the interface S11 of selector switch piece 3 and the interface S10 of main displaying block connect; When selecting the SW3 shelves, the interface S13 of selector switch piece 3 and S10 connect; When being changed to the SW2 shelves, the interface S12 of selector switch piece 3 connects sequential control piece 5.
As improvement of the present utility model, described selector switch piece 3 increases and connects a timer 6, when being changed to the SW2 shelves, starts timer 6.
With urn good fortune phosphate fertilizer plant of Wengfu Group Co., Ltd. sulfuric acid production plant is example, and certain reburner has 2 thermometer: A and B, requires one of them correct temperature data of 4 demonstrations of main displaying block on DCS, and DCS adopts Yokogawa CENTUM-CS system.When selecting switch 3 to be changed to the SW2 shelves, if thermometer A has when reporting to the police with mistake, system selects thermometer B as demonstration automatically; Otherwise if thermometer B has when reporting to the police with mistake, system selects thermometer A as demonstration automatically, reaches the purpose that automatic selection correct measurement parameter shows.
When selecting switch to be changed to the SW1 shelves, the data of DCS master's display module 4 displays temperature meter A, when being changed to the SW3 shelves, the data of DCS master's displaying block 4 displays temperature meter B reach and implement the purpose of manually selecting.
