The pass door opening/closing device according to the present embodiment I is constructed as described above, and the function I of this device will be explained below.

The circuit state shown in FIG. 2 is a state in which the movable contact (11) of the door opening/closing switch (υ) is switched to the closing fixed contact (lb), but the +B power is not applied.

Therefore, which relay circle ~ - coil (21dB22d
)(23g)(24g)(!5d) Mo is excited and the possible aa point czta)(22m)(23aX23b)(
24m) (24b) (25a) are as shown in the figure. Now, if the door is closed and 10B power is applied to the nine-shaped vagina, the coil of the first relay @υ (21d) and the coil of the second relay m field (22d) g: The current will move from the +B- source. The contact (22a) is switched to the first fixed contact (22b) again when the charging current of the capacitor 4 stops flowing. Therefore, when the door is closed and the path is running, only the coil <zld) of the first relay is energized, and the movable contact (21m) is switched to the second fixed contact (21c).

When the bus stops and the driver switches the movable contact (la) of the door opening/closing switch (1) to the open contact (lc) side, the coil of relay 3 falls through the diode (tzsg)g;
Current flows and its movable contact (23m) (23b) is j1
2m constant contact (23a) and 4th fixed contact (23f) *
Ren can be switched. The fourth fixed contact (23f) is this ε:
Solenoid valve coil (y) t = connected, but door open/close switch (1) 0 town excitation contact (ig) is already i: w11
II fixed contact (IC) g: Since it has been switched, the solenoid valve coil (1) is not yet excited and the door cannot be closed. On the other hand, 10B power is applied to the second fixed contact (23d) 42 via the door opening/closing switch (1),
This is obtained as a drive signal from the output cut-in wheel, and is supplied to the broadcasting device (5) shown in FIG. This is how the inside of the car feels: For example, from the installed speakers (6),
Please be careful as the door opens.'' is broadcast. Condensed? After the battle charging time has passed, the coil (23g) s
: Current no longer flows.

The movable contact (23M) (2:Th) is again the first fixed contact (
23C) and third constant contact (23・) side ε: switched, the drive signal from the ai car line (2) disappears,
Considering the time to broadcast the above mentioned content,
The capacity of the third fixed contact (2

The door begins to open.

On the other hand, in the first relay 4I, the coil (21d) is aWSed from the 10B power supply, so the movable contact (21m) is switched as shown in the figure. . Second relay-5; coil (22d)
is cut off from the 1B power supply, and a discharge current flows from the 1nd den t- through the coil (22d) and the resistor g tube,
This 6: The movable contact (22m) is connected to the second fixed contact (22m).
c), but since the movable contact (1m) of the door open/close switch (1) has already been switched to the open contact (lc), no drive signal can be obtained from the output line (9): If the discharge time of indenna memory is 8 times.

The movable contact (22m) is 111ji again as shown in the diagram!
Contact (22b) side I: Switched.

On the other hand, in the fourth relay W t=, the door-close switch (
1) t) 11 position switching and the coil # tw4g) l” current flows through the closing iode, and the movable contact (
24aB24b) is No. 24aB24b)! Fixed contact (244) and 41st contact
1tFIi point ($!4f) C can be switched, but as if improving, Cjl13 relay tssr and coil (23g
) Since the door cannot be closed while the water is flowing, the nasal obstruction position detection switch (It
) is 0 in the diagram; -itama-, and 11 is the 4th relay - 12 and the 2115th! 10B voltage has not yet been applied to one constant contact of contact (144) h, i.e. mud switch -), and ffy toswitch 佽) is not in standby state, however, as mentioned above. When the charging time of tn has elapsed and the door starts to open, the nasal obstruction position detection switch (3) closes, and the +B voltage is applied to the 4th relay -〇m2m'il contact (24d) and the 4th
1iil constant contact (24f) g: Added. This:
The mud switch 0) is in standby state C: when the coil (24g) is connected through the diode.
: Current flows. This C; from movable contact C2 axis X2+b
) (H constant contact (24d) (24f) @ t = self-holding. In other words, as described later, r-1 after this door l/I
Switch the vIS switch (1) again to the closed position so that no current is supplied from the diode side.

Movable contacts (24aX24b) unless the door is completely 42M
The fixed contacts (24d) (!4f) are closed, and the standby state of the mud switch θ) is maintained.

S relay I: Even when the door opening/closing switch (1) is switched to the open position, current flows through the coil (ml l), and the movable contact (251) is connected to the second fixed contact (15c).
Can be switched to @.

In the above state, if a step-square fault occurs at the pass entrance/exit, the mud switch 0) closes, and the fifth relay (fourth movable contact (ml l:, connected output line O) closes.
A drive signal is obtained from n and is applied to a predetermined audio signal forming circuit 1 of the broadcasting device (5). This l: 1 For example, if a person stands on the step of the 2 boarding entrance - 2 is ``Standing m
Please take the s,” was broadcast from the speaker (6).
Or, if two people stand on step C at the exit, C: can be broadcasted saying "Please be careful when getting off the train." Such a broadcast can be made in both cases. For 1:, simply install a new relay and mud switch with exactly the same configuration as the 5th relay in Figure 2 C2, and add one more output line.

1: Every time a passenger stands on the step of the entrance/exit.

Matt sui v? 0) repeats on and off.

For example, it is possible to repeatedly broadcast "Please take a RAM ticket," and it can be expected that all the passengers will get a C: Reliable C: Regular ticket. Even if the mud switch (6) is repeatedly turned on and off, the first ON drive signal is held for a predetermined period of time in the broadcasting device (inside the broadcasting device), and the signal is output every predetermined time.

It is also possible to make a predetermined broadcast.

Next, a case will be described in which the driver switches the door opening/closing switch (1) from the open position to the closed position.

That is, in this case, the movable contact C11 of the door open/close switch (1) is connected to the closing fixed contact (1b) 1:Jl, and the coil of the first relay (21(1) and the second relay The coils (2 d) are energized and their movable contacts (
21m) (!1m) is the 2nd ill constant point (21c) (2
2c) Confucian C; can be switched. On the other hand, a voltage of 10B is applied to the fourth constant contact (23f) of the SS relay. The movable contact (22m) of the second relay (to) is connected to the second fixed contact (22m).
2c) When switched to c-2.

A drive signal is obtained from the output line (-), and this is supplied to the broadcasting device (I) as a predetermined audio signal type 1LC1 circuit, and a message such as "Please be careful as the door is locked" is broadcast from the speaker (-). Ru. On the other hand, the door-close switch (1) is switched to the closed position C; it is switched and dropped.

A discharge current of 111″- of condensate flows through the coil (23g).

The movable contact (23M) (23b) is the 21st! IT constant contact (23d) and fourth constant contact (13f) c has been switched, and now f is the 41st! Since the electromagnetic coil (fic+B voltage is applied through the constant contact (23f), the electromagnetic coil (gin) remains energized and the door is still open\. Eventually, the charging time of the condenser -V''- After the passage of time,
The movable contact (23 hatake x 23b) is again the first fixed contact (23
c) and the 311th constant Qin point C23.) C; is switched, the solenoid valve coil (n becomes de-energized, and the door begins to close.

In addition, the □ drive signal from the output twin (11) described above flows through the movable contact (Ha
) is switched to the 111th FII point (fib) and disappears, but Conde y! --- The charging time or discharging time, that is, the time taken into account when the capacity is reduced and the time required to fold the battery to the announcement of ``Please be careful, the door is closed.''

As above, the door closes and the door enters.

At this time, when the nearest person stands on the step of the entrance/exit, the mud switch (O) turns on, and the nasal obstruction position detection switch (1) turns on.
# Since it is still closed, the 114 relay is self-holding, so the 4th v relay - 0 through the 2nd constant contact (2441) Matsu) switch [), the diode - 1 resistor - 5 3rd relay - 0 coil ( 13g) and the resistor -, and the movable contact (23m) (23b) of @39

Rinman! When the switch (4) is turned on, a drive signal is obtained from the output line (2) via the second fixed point (!le) and the contact point (21m) in the first relay ill. This is supplied to a predetermined audio signal type g circuit C; in the broadcasting device (1), and the speaker (6) broadcasts, for example, "Please do not stand on the steps" or "Please go up one step."'When the passenger leaves the step, the mass switch 0) is turned off, disappears in the drive signal from the first relay 4, and the third relay
The coil (23g) is de-energized again, and the movable contact (23b) is switched to the position shown, and the electromagnetic coil (23g) is de-energized again. This causes the door to close again. The door is completely closed; the closed nose position detection switch (1) is -*, and the 4th relay is activated.
4m) (24b) #111j1m1 pointrz*c)
and third fixed contact (24@) side g; switched.

As mentioned above, the door is closed.

If the nasal congestion position detection switch (1) fails and closes, C; is the 1115th relay of the 4th relay! A drive signal is obtained from the output line (2) through the contact (14C), and is supplied to the broadcasting device (S), which broadcasts the message "Please check the RQ IC" or a special message that only the driver can understand. The sound will be broadcast. In this case, the loudspeaker (6) may be used for broadcasting, but such broadcasting may be broadcast using a separate speaker placed near the driver.11! In the past, as mentioned above, even if the nasal obstruction position detection switch (3) malfunctioned, there was no alarm, resulting in various inconveniences and 9 cases.
According to this embodiment, such a failure can be detected immediately.

More than one shot! Regarding the O example, I&Kiku is, of course, 1
Various modifications can be made based on this 1: technical idea without being limited.

For example, door behavior 1: response 9 The predetermined broadcast is not the one mentioned above, but there are many possible broadcast contents.1 For example, the door closes and the time elapses. In this case, for example, a switch that is turned on when the door is closed may be provided, and the drive signal from this switch is sent to the broadcasting device (5) via an on-delay timer.
), select the audio signal forming circuits in a predetermined order, and broadcast. , connect multiple speakers.

Broadcast content 6: It may be possible to automatically switch depending on the broadcast content.

As described above, the pass door device of the present invention is provided with a broadcasting device that operates in response to the operation 1 of the door opening/closing switch, and automatically broadcasts a predetermined sound corresponding to the door behavior i.
Because of this, there is no need for drivers themselves to broadcast as in the past, and they can direct their attention to other departments.
The effect is that financial safety can be improved, and even the elderly and children can understand the content of the warning and take appropriate actions in response to appropriate instructions and warnings. It is something that plays.
