Abstract

The present invention relates to a kind of shagreen toilet train, nobody or someone use direction board, and feature includes: 24V AC power source, lavatory keeper conversion circuit, green light performance loop, red colored lamp performance loop and amber light performance loop.It is controlled by the keeper change-over switch of lavatory, and men and women's mark and text show lavatory state in which using three kinds of colors respectively, it may be assumed that when lavatory nobody in use, men and women's mark and text are shown using green light；When Toilet engaged in use, men and women's mark and text are shown using red light；When lavatory is stopped using, men and women's mark and text are shown using sodium yellow.Lavatory state in which is shown respectively using three kinds of colors by men and women's mark and text, keeps passenger very clear to lavatory virtual condition from far, effectively avoids that passenger runs away because judging sky by accident or empty waiting due to delays.

Description

Shagreen toilet train nobody or someone use direction board

Technical field

It is that nobody or someone use about a kind of shagreen toilet train the invention belongs to train and application of electronic technology field Direction board.

Background technique

The people's majority for sitting train had such experience, because of lavatory men and women mark and text ruler on shagreen train It is very little universal less than normal and only issue partially dark green light, so the farther away passenger of seat distances lavatory seems not eye-catching enough.In lavatory Institute nobody in use, lavatory dirty-green men and women identify side without any text importing；When Toilet engaged in use, beside it Can show " someone " printed words with red light, lavatory nobody or someone's two states show it is less intuitive, sometimes for some reason by attendant It locks after lavatory stops using, someone in lavatory is often also mistakenly considered by passenger and is used, the passenger having to go to the toilet is in lavatory foreign minister The time thing of waiting happens occasionally.Using shagreen toilet train of the present invention, nobody or someone can be effective using direction board Alleviate the generation of this embarrassing phenomenon.

Shagreen toilet train of the present invention nobody or someone use direction board, it passes through the keeper change-over switch of lavatory Control, men and women's mark and text show lavatory state in which using three kinds of colors respectively, it may be assumed that when lavatory nobody in use, male Female's mark and text are shown using green light；When Toilet engaged in use, men and women's mark and text are shown using red light；Work as lavatory When stopped using, men and women's mark and text are shown using sodium yellow.

Lavatory state in which is shown respectively using three kinds of colors by men and women's mark and text, makes passenger from far pair Lavatory virtual condition is very clear, effectively avoids passenger because erroneous judgement sky runs away or empty waiting due to delays.

Shagreen toilet train of the present invention described further below nobody or someone use direction board in implementation process Involved necessary, key technique content.

Summary of the invention

Goal of the invention and the utility model has the advantages that shagreen toilet train of the present invention nobody or someone use direction board, it is logical The keeper change-over switch control of lavatory is crossed, men and women's mark and text use three kinds of colors to show lavatory state in which respectively, it may be assumed that When lavatory nobody in use, men and women's mark and text are shown using green light；When Toilet engaged in use, men and women's mark and text It is shown using red light；When lavatory is stopped using, men and women's mark and text are shown using sodium yellow.Pass through men and women's mark and text Word shows lavatory state in which using three kinds of colors respectively, keeps passenger very clear to lavatory virtual condition from far, has Effect avoids passenger because erroneous judgement sky runs away or empty waiting due to delays.

Circuit operation principle: shagreen toilet train nobody or someone are turned using direction board circuit by 24V AC power source, keeper Change circuit, green light performance loop, red colored lamp performance loop and amber light performance loop composition.When lavatory nobody in use, door The common end COM (movable end) of bolt control change-over switch SW2 (single pole three throw switch) is transformed into contact a, at this moment green light work Obtained as circuit electric, green incandescent lamp HL1~HL4 energization starts to shine, and men and women's mark and text entire body is made to be lit into green；When Toilet engaged in use, the common end COM (movable end) of keeper change-over switch SW2 is transformed into contact b, and at this moment red colored lamp works back Rood electricity, red incandescent lamp HL5~HL8 start to shine, and men and women's mark and text entire body is made to be lit into red；When lavatory is closed When stopping using, the common end COM (movable end) of keeper change-over switch SW2 is transformed into contact c, and at this moment amber light performance loop obtains Electricity, yellow incandescent lamp HL9~HL12 start to shine, and men and women's mark and text entire body is made to be lit yellowly.

Technical solution: shagreen toilet train nobody or someone use direction board, it includes 24V AC power source, lavatory keeper Conversion circuit, green light performance loop, red colored lamp performance loop and amber light performance loop, it is characterised in that:

Lavatory keeper conversion circuit: it is made of power switch SW1 and keeper change-over switch SW2, the L of 24V AC power source Terminal meets the common end Com of keeper change-over switch SW2 by power switch SW1；

Green light performance loop: it is made of green incandescent lamp HL1~HL4, green incandescent lamp HL1~HL2 mutually contacts, Green incandescent lamp HL3~HL4 mutually contacts, and the contact a of keeper change-over switch SW2 connects upper end and the green of green incandescent lamp HL1 N-terminal of the lower termination 24V AC power source of the upper end of incandescent lamp HL3, the lower end of green incandescent lamp HL2 and green incandescent lamp HL4；

Red colored lamp performance loop: it is made of red incandescent lamp HL5~HL8, red incandescent lamp HL5~HL6 mutually contacts, Red incandescent lamp HL7~HL8 mutually contacts, and the contact b of keeper change-over switch SW2 connects upper end and the red of red incandescent lamp HL5 N-terminal of the lower termination 24V AC power source of the upper end of incandescent lamp HL7, the lower end of red incandescent lamp HL6 and red incandescent lamp HL8；

Amber light performance loop: it is made of yellow incandescent lamp HL9~HL12, and yellow incandescent lamp HL9~HL10 mutually goes here and there Even, yellow incandescent lamp HL11~HL12 mutually contact, the contact c of keeper change-over switch SW2 connect yellow incandescent lamp HL9 upper end and The upper end of yellow incandescent lamp HL11, the lower end of yellow incandescent lamp HL10 and the lower termination 24V AC power source of yellow incandescent lamp HL12 N-terminal；

One termination L terminal of 24V AC power source, another termination N-terminal of 24V AC power source.

Detailed description of the invention

Attached drawing 1 is lavatory men and women mark and text schematic diagram；Attached drawing 2 be shagreen toilet train provided by the invention nobody or Someone uses the circuit fundamental diagram of direction board one embodiment.

Specific embodiment

According to attached shagreen toilet train shown in Fig. 2, nobody or someone use direction board circuit fundamental diagram and attached drawing to say It is bright, and according to described in connection relationship between component in each section circuit described in summary of the invention and specific embodiment Component technical parameter require and circuit production main points carry out implement the present invention can be realized, with reference to embodiments to this hair Bright the relevant technologies are further described.

The technical parameter of component and its selection require
