Description
Technical field
The present invention relates to a kind of universal seclector, especially relate to a kind of universal seclector with remote monitoring function and status display function, belong to field of instrumentation technology.
Background technology
Universal seclector for electrical equipment control loop control, throw light on, protection, signal and procedure Selection; It selects break-make by stirring of knob to loop, therefore in use need often to send someone to go to scene to check the status of universal seclector knob, to grasp in real time its status, owing to lacking the mode of corresponding detected state, while manually checking, when instrument is long-time, use while causing panel wearing and tearing, often easily misunderstand the new employee of firm registration (especially for); And under the impact of the factors such as light, also make to check that personnel easily misunderstand; And manually the mode of checking wastes time and energy, increased the human resources support of enterprise, strengthened virtually the production cost of enterprise product, be unfavorable for the competitiveness of improving product.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, provide a kind of remote monitoring to show universal seclector, it can be monitored universal seclector status in real time.
The object of the present invention is achieved like this: a kind of remote monitoring shows universal seclector, on the rotation axis of described universal seclector, be set with a wiping sheet, in the shell of described universal seclector, be provided with a resistance ring, described rotation axis interts in the annular distance of resistance ring, and wiping sheet is connected with the anchor ring wiping of resistance ring; The wire of drawing on resistance ring accesses high level through pull-up resistor, and wiping sheet is through wire ground connection, and the tie point between resistance ring and pull-up resistor accesses microprocessor through wire.
Remote monitoring of the present invention shows universal seclector, and described microprocessor is connected with display module by driver module.
Remote monitoring of the present invention shows universal seclector, is also connected with communication module on described microprocessor.
Compared with prior art, the invention has the beneficial effects as follows:
The present invention is by the rheostat consisting of resistance ring and wiping sheet, the rotation status of rotation axis is converted to voltage, and receive, show by microprocessor, for staff, check, by electronics mode, rotation axis state is indicated, accurately and reliably, effectively raise its accuracy, avoided because of human error, the state judgement of rotation axis being made mistakes; And, also can the state information of rotation axis be passed to remote monitoring person by RS485 communication module, it is checked without carrying out scene, can to the state of a plurality of universal seclectors, monitor in real time and simultaneously, high efficient and reliable, and saved a large amount of human resources.
Accompanying drawing explanation
Fig. 1 is the partial structurtes schematic diagram that remote monitoring of the present invention shows the rotation axis place of universal seclector.
Fig. 2 is the electrical block diagram that remote monitoring of the present invention shows universal seclector.
Wherein:
Rotation axis 1, resistance ring 2, wiping sheet 3;
Microprocessor 101, communication module 102, power module 103, driver module 104, display module 105.
Embodiment
Referring to Fig. 1 and Fig. 2, a kind of remote monitoring the present invention relates to shows universal seclector, on the rotation axis 1 of described universal seclector, be set with a wiping sheet 3, in the shell of described universal seclector, be provided with a resistance ring 2, described rotation axis 1 interts in the annular distance of resistance ring 2, and wiping sheet 3 is connected with the anchor ring wiping of resistance ring 2---above-mentioned resistance ring 2 and wiping sheet 3 form rheostat Rs, when rotation rotation axis 1, rotation axis 1 drives wiping sheet 3 and resistance ring 2 to carry out relative sliding, thereby has changed the resistance of rheostat Rs;
The wire of drawing on resistance ring 2 is through pull-up resistor R access high level Vcc, wiping sheet 3 is through wire ground connection, tie point A between resistance ring 2 and pull-up resistor R accesses microprocessor 101 through wire, thereby makes microprocessor 101 can obtain in real time the voltage at this tie point A place; When rotation rotation axis 1, changed the resistance value of the rheostat Rs being formed by resistance ring 2 and wiping sheet 3, thereby the magnitude of voltage at the tie point A place of the bleeder circuit that consists of pull-up resistor R and rheostat Rs is changed, by microprocessor 101, can know this magnitude of voltage, thereby know this thing rotation axis 1 in which kind of state;
Described microprocessor 101 is connected with display module 105 by driver module 104, thereby the voltage at the tie point A place obtaining can be presented on display module 105, preferably, can by programming make magnitude of voltage and state one by one corresponding (in advance access voltage value and rotation axis 1 state one to one form in microprocessor 101, when microprocessor 101 is known magnitude of voltage, can obtain by above table the current state of rotation axis 1), thereby make display module 105 show the current state of the rotation axis 1 being transmitted by microprocessor 101, so more directly perceived, but even if not it should be noted that and by above-mentioned programming, the state of voltage and rotation axis 1 to be carried out correspondingly one by one, those skilled in the art can directly know according to magnitude of voltage the current state of rotation axis 1 equally,
Meanwhile, on described microprocessor 101, be also connected with communication module 102, described communication module 102 adopts RS485 module, thereby the state information of the rotation axis 1 of magnitude of voltage or correspondence is passed to long-range terminal equipment, is convenient to administrative staff and monitors long-range; So can make administrative staff at long-range monitoring state that simultaneously can be to a plurality of universal seclectors, and no longer need the personnel of arranging work to go to scene often to see, avoided checking because of people the error occurring, also a large amount of manpower and materials have been saved, be conducive to reduce the manufacturing cost of product, improve the competitiveness of product in market;
And the main innovate point of this patent is that how to convert the rotation status of universal seclector to the signal of telecommunication (magnitude of voltage) monitors and transmit; For microprocessor 101, communication module 102 etc., all can adopt existing module, without re-starting programming (only playing the effect that gathers and transmit data), so the electromechanical structure how protective of the required acquisition of this patent gathers is now in conjunction with the hardware circuit how to transmit;
In addition: need to be main, above-mentioned embodiment is only a prioritization scheme of this patent, any change that those skilled in the art does according to above-mentioned design or improvement are all within the protection range of this patent.
