In the matching circuit 7, the code is compared with a preset dedicated code for crime prevention driving stored in the memory circuit g. 9 matches above 1
This is a flip-flop that sets the pass signal Gτ, and the reset terminal of this flip-flop 9 is connected to the exclude or gate /θ, and this gate 10 has a car on the first floor (passenger during security operation). boarded IJ
A car position signal S1 when the car is stopped at a floor) and a running signal S2 when the car is running are input. The Q output of the flip-flop 7 is supplied to an elevator operation control circuit (not shown) as a car call signal S3 to the first floor. The car position signal S is applied to an AND gate // which has one input, and the output signal of this AND gate // is applied to its set terminal as a set signal of the flip-flop 7.2. , Also, the above-mentioned position signal S1 and running signal S are connected to the reset terminal of the flip 70 knob/2.
The output signal from the one-shot multivibrator /II triggered by the output signal of the NOR gate 13 having input 2 is applied via the NOR gate /s.

Also, 3.2 is a door control relay, and the relays ~ The door closes with the pink up action, and the door opens with the drawluff out action. In addition, the normally open contact 31b of the C travel operation relay is connected in parallel to the series circuit of the button switch 33.J4' and the safety switch contact 3S, and the door close switch and the safety switch contact 3S are connected in parallel. are respectively connected in parallel with the normally closed contact 30a of the timer relay 30 or the normally open contact 1ga of the relay 7g. .2 normally open contact J, 2a + 3-2b % A door closing circuit consisting of a contact 37 and a saw (resistance Jg), which are opened when the door is fully leapt, and a normally open contact of door control l---32. 1'dJ contact 3
(tl, H
Furthermore, the normally open contact /gb of the above relay /g is connected in parallel to the resistor 3g of the door closing circuit, and by short-circuiting the resistor 3g with the contact /gb during crime prevention operation, the resistance is higher than usual. The motor 3 is controlled to open the door at a fast speed.

Next, the operation of the inventive device configured as described above will be explained.

When the elevator is in normal descending operation, a passenger who wishes to operate the crime prevention operation at the first floor landing can press the PIN code 1, for example 1 → 8 → 9, by operating the numeric keypad. The code is written in register AK. The pin code entered in this register 6 is checked in the matching circuit t against the special code for crime prevention driving stored in the memory circuit t, and if it matches,
A match signal is sent, thereby checking the flip-flop 9. When flip-flop 9 is cent, lU
? Depends on c. 71.1. The force "11" is transmitted to the first floor jump signal s3 and the Lc elevator control circuit to register the first floor landing rrP.

At this time, the elevator, which is in the process of descending, is summoned to the floor while responding to the call and landing FpK in sequence.

When the elevator car arrives at the 1st floor, the 1st floor car position signal -AS becomes "II"', so this car position [

The condition is met.

Set the output to "II" and convert it into a flip-flop/, 2
7 times. By setting 120 and 7, the elevator is put into a crime prevention operation condition (Kd (2)).

When Flip Front Guard 2 is set, its Q output "IT" gives an operation command to the display kNO, lights up the display S, and displays "1 during crime prevention driving. Lip flop/J output “'TI”
The AND gate/O is activated by the car position signal s1, and the output number is applied to the relay/g via the interface/7, thereby causing the relay/g to be activated. Furthermore, by adding the above-mentioned 7 lip flops/, 2]Q output "Il" to the one-shot multivibrator, the multivibrator, 2. ．． 2 sends a signal S, thereby canceling the car call in bulk,
Furthermore, the gate circuit 3 is disabled for general passenger calls, and the elevator car is exclusively reserved for passengers who have instructed security operation.

After that, the Q output of flip-flop /, 2 11 ■Iu
Before the one-shot multivibrator/wa triggered and reversed returns to its original stable state, that is, if a car call is registered by a passenger who has instructed crime prevention driving within 5 seconds, the no car call signal S4 goes low. Therefore, even if the one-shot multivibrator /, 5- is triggered after 5 seconds, the AND gate 1 does not send out a reset signal to the flip-flop /λ. However, if the car call is not registered even after 5 seconds pass, a reset signal is sent from the AND gate U/, which causes the flip-flop/
This will reset U and disable the elevator's security operation mode.

On the other hand, when the elevator car reaches the first floor and stops, the traveling signal "5 S2 is II LM, and the car position signal S is 'H.
``, so the output of the gate IO becomes ``H'', which resets the flip-flop 9 and at the same time the car sowing signal S8 to the first floor also becomes ``L 11''.
becomes.

Also, when the elevator car stops at the first floor, it runs '1'l (not shown)! The timer relay 3θ drops out, the 1st and 7th points, and 3/a are opened, and then when the timer relay 3θ passes for 4 seconds, the timer relay 3θ drops out.

At this time, crime prevention)il,! In the first state when the rotation is established,

The circuit of gb-contacts J, 1a-H closes L1, thereby closing the door at a faster rate than usual.

This is because the resistor 3g is short-circuited by the contact /gb of the relay /g. -1, safety switch 1 during crime prevention driving
Since point 3S is short-circuited by contact 1ga of relay 1g, the door safety function is disabled. This rJ, :1'
-1-Beta is reserved for passengers who have instructed 1(/I criminal driving) to prevent molesters from boarding the vehicle.

'fr, oh, if a passenger who gets into an elevator car that is set to security operation mode presses the door open button switch 33 at the same time as getting into the car, the door control relay 3.2 is energized and the motor 3A is activated. The circuit for closing the door is closed, and the two doors are closed simultaneously.

If a passenger who jumps into the car VC after or before the door is closed presses the destination floor car call button to register the car call, the car will run directly to the destination floor, and if it stops after arriving at the destination floor, Door control relay 3 due to dropout of driving relay

-Deki Z). Furthermore, when a passenger who has instructed security driving gets on board, the door is immediately closed at a speed of ri'+, so that it is possible to effectively prevent someone else from driving on the same side.

1-R),! In the 17 actual cases, a method of entering a memorized code for crime prevention driving and a numeric keypad in 17 were used,
An input method using a magnetic node or a method in which a flat call button is operated using a Morse code method or the like may be used. In addition, this code may be set to 1, the floor of the resident, the date, and the day of the day (2), such as 1, for evening.

Also, the PIN code input method d Cart (rll is also the same as 11.
7, the hassle of call registration within the car can be saved. In addition, there is also a boarding call, Vte Jllll.
You may do so. You can also set the number of people riding when you set up the password hood, and then open the door immediately after counting up to the set number of people.

Furthermore, if it is detected that a molester etc. has appeared,
It is also possible to display a warning in the landing area, manager's room, etc. Further, after the crime prevention mode is detected as described above, a device 'i'f or the like may be used to detect when a person enters the car using the light 71, and the door may be immediately closed.

Furthermore, the situation inside the car may be monitored by a manager's room or a remote monitoring center only during crime prevention operation.

As explained above, this invention is provided with an input means for setting crime prevention driving with a special code at the boarding point of Nire-Sita, and if the crime prevention driving mode is set by operating the input means, In addition to displaying this information on the outside, we made it invalid for calls other than passenger car calls (+: r V), so there was no room for molesters etc. to take advantage of it.
