Abstract
A control device for DCS emulation in power plants is provided, which is connected with analog quantity and digital quantity modulus of DCS control cabinet. The utility model comprises a button switch embedded in the installation panel, a liquid crystal display screen, and a phase-wound potentiometer. Wherein, the phase-wound potentiometer is used to change the value of analog input and directly feed back the value to the DCS operating system of DCS control cabinet for the feedback to the site instrument and implementation mechanism; button switch is used to control digital quantity and directly feeds back the value to the DCS operating system of DCS control cabinet. With the above technical solution, the utility model reduces the use of emulation in the purely virtual and purely normal working condition, and is installed on DCS control cabinet, and adopts the visual emulation more conforming to the site working condition under the status of real electricity.
Description
Technical field
The utility model relates to a kind of Power Plant DCS Simulation Control device, directly is installed in the DCS control cubicle, with the analog quantity in the control cubicle, digital module links to each other, the analog quantity on the modifier, the parameter of digital quantity, can be more intuitive, the more effective emulation that participates in the DCS system.
Background technology
Existing DCS (scattered control system) emulation all is on computers, not under real electricity condition, and just utilize the software of DCS, change analog quantity on computers, the parameter of digital quantity is come emulation, can only reach a kind of virtual state, can not with some field instruments, actuator connects, understanding field instrument that can not be definite intuitively, actuator's operating state.
And the virtual emulation on the computer is all to be the various emulation of finishing under the normal operating conditions at the medium that guarantees various transmission information, has certain limitation.
The utility model content
The purpose of this utility model is to provide a kind of DCS Simulation Control device that meets field working conditions more, with use a computer emulation under pure virtual, the pure normal operating mode of minimizing, be directly installed on the DCS control cubicle, adopt under real electricity condition, more directly perceived, more meet the emulation of field working conditions.
The control device that a kind of Power Plant DCS emulation is provided provided by the utility model, link to each other with analog quantity, the digital module of DCS control cubicle, it is characterized in that: comprise the push-button switch, LCDs and the Wound-rotor type potentiometer that are embedded on the installation panel, wherein: the Wound-rotor type potentiometer is used to change the value of analog quantity input, and directly feed back to the interior DCS operating system of described DCS control cubicle, to feed back to field instrument and on-the-spot actuator; Push-button switch is used for the control figure amount, and directly feeds back to the DCS operating system in the described DCS control cubicle.
Owing to adopted above-mentioned technical solution, the emulation of the utility model under minimizing uses a computer pure virtual, pure normal operating mode is directly installed on the DCS control cubicle, adopts under real electricity condition, and is more directly perceived, more meets the emulation of field working conditions.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the control device of the utility model Power Plant DCS emulation links to each other with analog quantity, the digital module of DCS control cubicle, comprises 11,4 LCDs 12 of 32 push-button switches and 4 Wound-rotor type potentiometers 13 of being embedded on the installation panel 1, wherein:
Wound-rotor type potentiometer 13 is a conventional products, is used to change the value of analog quantity input, and directly feeds back to the DCS operating system in the described DCS control cubicle, to feed back to field instrument and on-the-spot actuator;
Push-button switch 11 is a conventional products, is used for the control figure amount, and directly feeds back to the DCS operating system in the described DCS control cubicle.
Press the digital quantity push-button switch, just have 0 to be changed to 1 digital quantity, be sent in the DCS analogue system by digital module, the corresponding digital amount of seeing on the display screen 12 is put 1, and field instrument and actuator make corresponding feedback.
Press the analog quantity push-button switch, the parameter of regulator potentiometer then, change the parameter of analog quantity input, be sent in the DCS analogue system by analog module, see the parameter of corresponding analog quantity on the display screen 12, program by simulation software changes field instrument, the operating state of actuator.
In sum, be pure virtual for existing analogue system, under real electricity condition, do not carry out emulation yet, have significant limitation, artificial site operating mode really, the utility model device can the truer emulation of carrying out intuitively under the real electricity condition.
The above only is a preferable possible embodiments of the present utility model, the scope of non-so inflexible limit patent application of the present utility model, so the equivalent structure that all utilization the utility model specifications and accompanying drawing content are done changes, and all in like manner is contained in the scope of the present utility model.
