Abstract
The present invention relates to a kind of train closet, nobody or someone use display device, its feature includes nobody or someone of train closet using display device, it includes 12V DC power supply, decompression adaptation and keeper control conversion circuit, green LED performance loop, red light emitting diodes performance loop.Nobody or someone of train closet are to control change-over switch by lavatory keeper using display device, so that men and women's cartoon mark and text use two kinds of colors to show state respectively, that is: when lavatory is unmanned to be used, lavatory men and women's cartoon mark and text are shown using green light, when Toilet engaged in use, lavatory men and women's cartoon mark and text are shown using red colored lamp.By men and women's cartoon mark and the double-colored display mode of text, passenger in compartment can accurately identify lavatory state in which from far, avoid because passenger do not see erroneous judgement sky run away or it is empty wait due to waste time.
Description
Technical field
It is that nobody or someone use display about a kind of train closet the invention belongs to train and application of electronic technology field
Device.
Background technique
The people for sitting train largely have such experience, because of (especially shagreen train) lavatory cartoon on train
It is generally smaller to identify size, so that the farther away passenger of seat distances lavatory seems very not eye-catching, lavatory men and women's cartoon mark
Majority is that dirty-green is always on display state.Lavatory nobody in use, lavatory dirty-green mark side without any text importing, only
In someone in use, can just be displayed in red " someone " printed words beside it, lavatory nobody or someone's two states show very not straight
It sees, after even artificially being locked by attendant sometimes, is also used through being often mistakenly thought of as someone, have the passenger that has to go to the toilet long outside lavatory
The time thing of waiting happens occasionally.What method this awkward thing can be effectively relieved with to occur?
Train closet of the present invention nobody or someone use display device, it is opened by the control conversion of lavatory keeper
Close, so that men and women's cartoon mark and text use two kinds of colors to show states respectively, it may be assumed that when lavatory nobody in use, lavatory men and women
Cartoon mark and text are shown using green light；When Toilet engaged in use, lavatory men and women's cartoon mark and text use
Red colored lamp is shown.By men and women's cartoon mark and the double-colored display mode of text, energy is accurately from far by passenger in compartment
It identifies lavatory state in which, avoids that erroneous judgement sky runs away or empty waiting due to wastes time because passenger does not see.
Train closet of the present invention described further below nobody or someone use display device institute in implementation process
It is related to necessary, key technique content.
Summary of the invention
Goal of the invention and the utility model has the advantages that nobody or someone of train closet using display device are turned by the control of lavatory keeper
Switch is changed, so that men and women's cartoon mark and text use two kinds of colors to show states respectively, it may be assumed that when lavatory nobody in use, lavatory
Men and women's cartoon mark and text are shown using green light, when Toilet engaged in use, lavatory men and women's cartoon mark and text are equal
It is shown using red colored lamp.By men and women's cartoon mark and the double-colored display mode of text, passenger in the compartment energy from far
Lavatory state in which is accurately identified, avoids that erroneous judgement sky runs away or empty waiting due to wastes time because passenger does not see.
Circuit operation principle: nobody or someone of train closet are suitable by 12V DC power supply, decompression using the circuit of display device
Match and keeper control conversion circuit, green LED performance loop and red light emitting diodes performance loop form.Work as lavatory
Nobody in use, because keeper control change-over switch SW2 (single-pole double throw microswitch) common end COM (movable end) be in
Normally off, at this moment green LED performance loop obtains electric, and green LED LED1~LED8 starts to shine, and makes male
Female's cartoon mark and text are put into bright green.When Toilet engaged in use, because the common end of keeper control change-over switch SW2
The switching of COM (movable end) is switched on normally opened contact, and at this moment red light emitting diodes performance loop obtains electric, two pole of emitting red light
Pipe LED9~LED16 starts to shine, and men and women's cartoon mark and text is made to be lit into red.
Technical solution: train closet nobody or someone use display device, it include 12V DC power supply, decompression adaptation and
Keeper controls conversion circuit, green LED performance loop, red light emitting diodes performance loop, it is characterised in that:
Decompression adaptation and keeper control conversion circuit: it is opened by the control conversion of power switch SW1, dropping resistor R1 and keeper
SW2 composition is closed, circuit anode VCC connects one end of dropping resistor R1, another termination door of dropping resistor R1 by power switch SW1
The common end Com of bolt control change-over switch SW2；
Green LED performance loop: it is made of highlighted green LED LED1~LED8, keeper control
The left side contact of change-over switch SW2 connects the anode of highlighted green LED LED1 with highlighted green LED LED5's
Anode, circuit GND connect the cathode of highlighted green LED LED4 and the cathode of highlighted red light emitting diodes LED8, it is high
1~LED4 of bright green Light-emitting diode LED mutually contacts, highlighted green LED LED5~LED8 mutually contacts；
Red light emitting diodes performance loop: it is made of highlighted red light emitting diodes LED9~LED16, keeper control
The right side contact of change-over switch SW2 connects the anode and highlighted red light emitting diodes LED13 of highlighted red light emitting diodes LED9
Anode, circuit GND connect highlighted red light emitting diodes LED12 cathode and highlighted red light emitting diodes LED16 it is negative
Pole, highlighted red light emitting diodes LED9~LED12 mutually contacts, highlighted red light emitting diodes LED13~LED16 mutually goes here and there
Even；
The anode of 12V DC power supply meets circuit anode VCC, the cathode of 12V DC power supply with connecing circuit GND.
Detailed description of the invention
Attached drawing 1 is lavatory men and women's cartoon mark and text；Attached drawing 2 is that train closet provided by the invention nobody or someone makes
With the circuit fundamental diagram of display device one embodiment.
Specific embodiment
According to attached train closet shown in Fig. 2, nobody or someone use display device circuit fundamental diagram and attached drawing to say
