Description
Technical field
This utility model relates to a kind of command signal input system, belongs to field of industrial automation control, nuclear power field.
Background technology
Current DCC keyboard does not have failure judgement unit, cut-off unit and alarm unit, if producing rub-out signal, it is impossible to the transmission of judgement timely, warning pick-off signal.
Summary of the invention
For solving one of technical problem of existence in above-mentioned prior art, this utility model provides a kind of command signal input system.
This utility model solves its technical problem and be the technical scheme is that
A kind of command signal input system, including keyboard, also includes breakdown judge module, alarm module and cut-off module, and described keyboard connects described breakdown judge module, and described breakdown judge module is connected to alarm module and cut-off module.
Wherein:
Keyboard, including function button and digital keys, is used for sending command signal；
Breakdown judge module, judges for the command signal that keyboard is sent；
Alarm module, reports to the police to the rub-out signal sent, and when receiving warning drive signal, drives buzzer by optocoupler, reports to the police；
Cut-off module, ends rub-out signal, it is prevented that the transmission of rub-out signal.
This utility model also has following additional technical feature:
Preferably, described breakdown judge module is STM32 central processing unit.
Preferably, also including signal transmission module, described breakdown judge module is respectively connected with alarm module and cut-off module by a signal transmission module.
Preferably, described signal transmission module is PC375B optocoupler.
Preferably, described alarm module is buzzer.

Beneficial effect:
Command signal input system of the present utility model increases prompt functions by increasing signal judge module, and increases the function of rub-out signal cut-off, it is possible to signal is made effective judgement, it is ensured that the correct transmission of signal；Warning function can be produced for rub-out signal, allow users to find in time operational error；Can end for rub-out signal, it is to avoid the transmission of rub-out signal.
Additional aspect of the present utility model and advantage will part provide in the following description, and part will become apparent from the description below, or is recognized by practice of the present utility model.
Accompanying drawing explanation
Above-mentioned and/or additional aspect of the present utility model and advantage are from conjunction with will be apparent from easy to understand the accompanying drawings below description to embodiment, wherein:
Fig. 1 is the structural representation of this utility model command signal input system.
Description of reference numerals:
Dual system selects module 1；Digital keys module 2；Function button module 3；STM32 central processing unit 4；Oneth PC375B optocoupler 5；Buzzer 6；ADG508 analog switch 7；Other system 8；2nd PC375B optocoupler 9.
Detailed description of the invention
The embodiment described below with reference to accompanying drawing is illustrative of, and is only used for explaining this utility model, and it is not intended that to restriction of the present utility model.
A kind of command signal input system according to this utility model embodiment is described with reference to the accompanying drawings.Fig. 1 is the structural representation of this utility model command signal input system.
A kind of command signal input system, including keyboard, also include breakdown judge module, alarm module and cut-off module, described keyboard connects described breakdown judge module, described breakdown judge module is connected to alarm module and cut-off module, also including signal transmission module, described breakdown judge module is respectively connected with alarm module and cut-off module by a signal transmission module.
Wherein:
Keyboard, including function button module 3 and numeral key-press module 2, is used for sending command signal；
Breakdown judge module, judges for the command signal that keyboard is sent；
Alarm module, reports to the police to the rub-out signal sent, and when receiving warning drive signal, drives alarm to sound by optocoupler and reports to the police；
Cut-off module, ends rub-out signal, it is prevented that the transmission of rub-out signal.
Concrete:
Described breakdown judge module is STM32 central processing unit 4；
Described signal transmission module is PC375B optocoupler 5 and a 2nd PC375B optocoupler；
Described alarm module is buzzer 6；
Described cut-off module is ADG508 analog switch 7.
Operational approach: operator is ordered by digital keys module 2 and function button module 3 input on keyboard, now command signal enters STM32 central processing unit 4, when processing chip STM32 and receiving signal, compare with correct command signal to the received signal through routine processes.If right instructions, STM32 central processing unit 4 can drive ADG508 analog switch 7 to close to ensure that signal is correctly transferred in other system 8；Reporting to the police if the command signal of mistake just drives buzzer to sound by a PC375B optocoupler 5, being driven the connection disconnecting ADG508 analog switch 7 by the 2nd PC375B optocoupler 9, thus ensureing the transmission of pick-off signal simultaneously.
Operation principle: after dual system selects to select switch to determine in which system of use in module 1, the input of order is carried out by digital keys and function button, breakdown judge module will be entered after command signal, if signal is correctly just transmitted directly to next stage, if signal error will enter alarm module, alarm module sends warning, prompting operated by personnel's error；The transmission of cut-off module cut-off rub-out signal can be started, it is to avoid rub-out signal is transferred in next stage system simultaneously.
While there has been shown and described that embodiment of the present utility model；It will be understood by those skilled in the art that: when without departing from principle of the present utility model and objective, these embodiments can be carried out multiple change, amendment, replacement and modification；Scope of the present utility model is limited by claim and equivalent thereof.
