Abstract

PURPOSE:To prevent elevator users from entering a floor of a crime by mistake into, in the case of passengers in a cage being detected, when a burglar alarm detection means detects a crime floor by preventing from stopping at the floor with a passenger-cargo stop-at-crime floor prevention means. CONSTITUTION:When passengers are in a cage, an in-cage no-passenger detection circuit 2 is actuated, thereby suspending the excitation of a relay coil 2a, so that no-passenger detection normally-open contacts 2a-1-2a-8 open and the normally-closed contacts thereof 2b-1-2b-2 close. A burglar alarm device actuates a burglar alarm detection circuit 13 at a third floor, thereby exciting a relay coil 13a, so that a burglar alarm detection normally-open contact 13a-1 at the third floor closes and burglar alarm detection normally-closed contacts 13b-1, 13b-2 at the third floor open. In this case, when a boarding DOWN button at the third floor is pressed so that a boarding DOWN call at the third floor is made, a boarding DOWN button circuit 203 at the third floor excites a relay coil 203a, so that boarding DOWN detection normally-open contacts 203a-1, 203a-2 at the third floor close.

Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an elevator operating device, and in particular to an elevator operating device that can only capture criminals who commit crimes indoors and attempt to escape by elevator. It is related to.

[Prior Art] Conventionally, as an example of this type of elevator operating system, as shown in Japanese Utility Model Publication No. 58-20811,
When a crime occurs indoors, a switch installed on each floor is operated to artificially disable the elevator service that calls the hall on the floor where the crime occurred, cutting off the criminal's escape route.
This was designed to prevent them from escaping.

As another example, as shown in Japanese Patent Application Laid-Open No. 59-53381, an abnormality detection device is installed inside the car, and when this detection device detects an abnormality, the car is automatically moved to a specific floor. Is there something that makes it go straight?

[Problem to be solved by the invention] However, in order to cut off the escape route for criminals by disabling the elevator service on the floor where the crime occurred, the staff must check the crime prevention alarm by using the switch installed on each floor. Because it is operated manually after a crime occurs, it takes time from the time a crime occurs until the service for the person with the disability is cut, there is a risk of accidentally operating a floor other than the one in question, and there is a risk that the service cut will cut off the exit route. Since it is easy for criminals to know that they have committed a crime, there is a problem in that it adds extra stimulus to criminals.

In addition, the latter method, which automatically directs the car directly to a specific floor by detecting an abnormality inside the car, cannot detect crimes that occur indoors (outside the car), so if a criminal flees from inside the car, the crime cannot be detected. There was a problem that if the driver got into the vehicle without any problems, the driver would continue to drive normally and end up helping the vehicle escape.

The present invention was made in order to solve the above-mentioned problems, and it forcibly confines criminals who commit a crime indoors and try to escape in an elevator into the elevator car, and disables future operation. The object of the present invention is to obtain an elevator operation device that can actively capture the objects.

[Means for Solving the Problems] When a landing button provided at a landing on each floor is pressed, the elevator operating device according to the present invention travels the car to that floor and stops, and also operates a destination button in the car. In the elevator operation device, which moves the car to the floor corresponding to the destination button when the button is pressed, there is a crime prevention alarm detection means that detects a crime floor based on a signal from a crime prevention alarm circuit installed for each floor, and a crime prevention alarm detection means that detects a crime floor and detects whether there are passengers in the car. an unattended in-car detection means for detecting whether there is a person in the car;
means for preventing a manned car from stopping on the crime floor when the car is detected by the crime prevention alarm detection means and the car is not stopped on the crime floor when the car unmanned detection means detects that there is a passenger in the car; When the hall call button on the crime floor is pressed, if the unoccupied car detecting means detects that there are no passengers in the car on that floor, a traveling means that causes the unmanned car to travel to the crime floor. When the car is stopped by the traveling means on the crime floor detected by the crime prevention alarm detection means and the car unoccupied detection means detects that a passenger has boarded the car, the door opening button is disabled and the car is immediately stopped. The elevator is equipped with a forced door closing means for closing the door, and a halting means for suspending the subsequent operation of the elevator when the forced door closing means is activated.

[Function] In this invention, when the presence of a passenger in the car is detected by the car unoccupied detection means and the crime prevention alarm detection means detects a crime floor, the manned car is prevented from stopping on the crime floor. Preventing means from stopping the car on its crime floor.

In addition, if the car unoccupied detection means detects that there are no passengers in the car, and the landing call button on the crime floor is pressed, the traveling means causes the unmanned car to travel to that floor. The car is stopped at the crime floor detected by the crime prevention alarm detection means.

When the car unoccupied detection means detects that a passenger has boarded the car, the car door is immediately closed and the elevator operation is suspended thereafter.

(14) is not operating, and the security alarm normally open contacts (lla-1) and (L4a-2) shown in Figure 1(b) are normally open, and the security alarm for the 1st to 4th floors is Normally closed contact for detection (ll
During normal times when b-1) to (14b-2) are always closed, for example, if the elevator is stopped on the first floor, 3
When the DOWN hall button of the floor is pressed and the DOWN hall button circuit (203) of the third floor shown in Fig. 1(C) or the relay coil (203a) is excited, the 3rd floor shown in Fig. 1(b)
The normally open contacts (203a-1) and (203a-2) for detecting the DOWN of the landing on the floor are closed.

Then, as shown in FIG. 1(b), (+) - Normally closed contact for detecting security alarm on the 3rd floor (13b-1) - Diode 2-3
Normally open contact for detecting floor landing DOwN (203a-1) - normally closed contact (23b) - normally closed contact (24b) - UP Direction command circuit (1) - Closed in the (-) circuit.

Then, when the UP direction command circuit (3) operates and the known elevator starting conditions are established, the elevator car is moved up to the 3rd floor.
Let it run.

Next, when the elevator car changes from the second floor to the third floor, the normally open contact (23a-1) that detects that the car position shown in FIG. 1(b) is on the third floor closes, and as shown in FIG. As shown in (b), the normally open contact (2
03a-2) - Normally closed contact for detecting security alarm on the 3rd floor (13
b-2) - (238>- Stop determination circuit (5) - Closed at (-).

Then, the stop determining circuit (5) operates to stop the car on the third floor.

This allows all calls to be answered in sequence when the security alarm system is not operating in the same sequence as above.

Next, we will explain the sequence when the security alarm system on the third floor is activated while a passenger is riding in the car on the first floor, and the third floor landing is called DOWN. When a passenger is in the car, the in-car unoccupied detection circuit (2) in Fig. 1(a) operates to stop the excitation of the relay coil (2a), and the circuit in Fig. 1(b) operates.
) Normally open contacts for unattended detection (2a-1) ~ (2a-
8) is opened, and its normally closed contacts (2b-1) and (2b-
2) or close the circuit. The security alarm system (not shown) operates the security alarm detection circuit (13) on the third floor and activates the relay coil (13).
a) and connect the normally open contact (13) for detecting the security alarm on the third floor.
a-1) is closed, and the normally closed contacts (13b-1) and (13b-2) for detecting the security alarm on the third floor are opened. At this time, for example, if the 3rd floor landing DOWN button is pressed and the 3rd floor landing DOνN call is made, the 3rd floor landing DOWN button circuit (203) shown in FIG. 1(C) excites the relay coil (203a). , the normally open contact (203a-1) for detecting DOνN on the third floor shown in FIG.
203a-2) is closed.

Therefore, since the normally open contact for unoccupied detection (2a-3) is open, the (10) - normally open contact for unoccupied detection (2a-3) - diode 2-3 floor shown in FIG. Boarding area DOW
Normally open contact for N detection (203a-1) - Normally closed contact (23b
) - Normally closed contact (24b) - U P direction command circuit (3)
-(-) is not formed.

Furthermore, as shown in Figure 1 (b), since the normally closed contact (13b-1) for detecting the security alarm on the third floor is open, the (+) - third floor as shown in Figure 1 (b) Normally closed contact for crime prevention alarm detection (13b-1) - diode 2nd-3rd floor landing DOWN
Normally open contact for detection (203a-1) - normally closed contact (23b)
- Normally closed contact (24b), up direction command circuit (3
)-(-) circuit is not formed, and the direction command circuit (3) corresponding to the call on the third floor cannot operate.

Next, if the passenger in the car presses the 4th floor destination button on the destination control panel, the 4th floor destination button circuit (34) shown in FIG. 1(a) excites the relay coil (34a), The normally open contacts (34a-1) and (34a-2) for destination registration detection on the fourth floor shown in FIG. 1(b) are closed.

However, since the normally open contact (2a-4) for unoccupied detection is open because there is a passenger on board, the normally closed contact (14b-1) for detecting the security alarm on the 4th floor is open as shown in Figure 1(b). ) - Normally open contact for destination registration detection on the 4th floor (34a-1) - Normally closed contact (
24b) -UP The circuit of the P direction command circuit (3) is formed and the car runs in the UP direction, but even if the car runs UP, the normally open contact for unoccupied detection (2a-7) is open. Therefore, the (+)-3rd floor landing DOWN shown in Figure 1(b)
The circuit of normally open contact for detection (203a-2) - normally open contact for unattended detection (2a-7) - normally closed contact (23a-1) - stop determination circuit (5) - (-) is not formed.

Furthermore, the normally closed contact for detecting the security alarm on the third floor (13b-2)
Since the circuit is opened, the normally open contact (203a-2) for detecting DOWN on the (+)-3rd floor landing shown in FIG. 1(b) -3
It is not possible to stop on the third floor because the circuit of normally closed contact (13b-2) for crime prevention alarm detection on floor - normally open contact (23a-1) - stop decision circuit (5) - (-) is not formed.

Then, when the passenger arrives at the 4th floor and the passenger gets off the car and the car becomes unoccupied, the in-car unoccupied detection circuit (2) is activated and the relay coil (2a) is energized, as shown in Figure 1 (b). The normally open contacts (2a-1) to (2a-8) for unoccupied detection shown in (2a-1) to (2a-8) are closed.

Then, as shown in FIG. 1(b), (+) - Normally open contact for unoccupied detection (2a-3) - Diode 2nd-3rd floor landing DO
Normally open contact for WN detection (203a-1) - Normally closed contact (22
b) -Normally closed contact (21b) -DOWN direction command circuit (4) -(-) The I)OvN direction is set by the circuit.

In other words, after detecting that a passenger has disembarked from the car, it responds to the hall call on the alarm floor (criminal technique).

Then, when the car is running DOWN and the car position signal changes from the 4th floor to the 3rd floor, the normally open contact (23a = 1) closes, and the normally open contact for detection of the landing DCIWN on the 3rd floor (203a-2)
, since the normally open contact for unattended detection (2a-7) is closed,
(+) shown in Fig. 1(b) - Normally open contact for detecting DOWN on the third floor landing (203a-2) - Normally open contact for detecting unoccupied person (2a
-7) - Normally open contact (23a-1) - Stop decision circuit (5)
A stop determining circuit (5) operates in the -(-) circuit and stops the unmanned car on the third floor in response to the landing DOWN button on the third floor.

Does the above explanation apply to the security alarm system floor or intermediate floor?
When the crime prevention alarm detection circuit (14) on the fourth floor, which is the top floor, is activated while the car carrying passengers is traveling toward the DOWN call on the top floor, its relay coil (14a) is energized.
Since the crime prevention alarm device is activated and the normally open contact (14a-2) for detecting the crime prevention alarm on the 4th floor is closed, when the car reaches the 3rd floor, the normally open contact (23a-1) closes and the first Figure (b
) As shown in (+) - 4th floor landing hall DOWN detection normally open contact (204a-2) - UP running detection normally open contact (204a-2)
15a-1) -Normally open contact for detecting security alarm on the 4th floor (t4
a-2) - Normally closed contact for unoccupied detection (2b-2) - Normally closed contact for third floor security alarm detection (13b-2) - Normally open contact (23
a-1) - Stop determination circuit (5) - A circuit (-) is formed to forcibly stop the vehicle on the third floor.

Therefore, when there are passengers on board, the car cannot run to the fourth floor.

Next, while the car carrying passengers was running toward the bottom floor landing UP call, the security alarm detection circuit (1
1) is activated, its relay coil (lla) is excited, the security alarm system is activated, and the normally open contact (1) for security alarm detection on the first floor shown in Figures 1(c) and 1(b) is activated. ,1a
-2) is closed, so when the car reaches the second floor, the normally open contact (22a-1) shown in Figure 1(b) closes, and the (+) -1st floor shown in Figure 1(b) closes. Normally open contact for landing UP detection (101a-2) - Normally closed contact for unattended detection (2b-1)
- Normally open contact for detecting security alarm on the first floor (lla-2) -D
OWN Normally open contact for traveling detection (16a-1,) - Normally closed contact for first floor security alarm detection (12b-2) - Normally open contact (2
2a-1) - Stop determination circuit (5) - A circuit (-) is formed to forcibly stop the vehicle on the second floor. Therefore, the car cannot run to the first floor when passengers are on board.

Next, when the unmanned car with no passengers on it reaches the third floor, which is the crime floor, the door is opened and the normally closed contacts for door opening/closing detection (L8b-1) and (18b- 2
) returns to its original state and closes the circuit.

When a passenger (criminal) gets into the car and cuts off the light beam of the optical sensor of the boarding/alighting detection circuit (17) provided on the car door (not shown), the boarding/alighting detection circuit shown in FIG. 1(C) is detected. Since the normally open contact (17a-1) is closed, Fig. 1 (C
) Shown in (+) - 3rd floor security alarm detection normally open contact (13
a-1) - Normally open contact (23a-2) - Normally open contact for boarding/exiting detection (17a-1) - Door opening/closing contact (18b-1) - Reset switch contact (19-1) - Boarding detection relay (
6a) -(-) circuit is formed.

Then, the occupancy detection relay (6a) is energized, and as shown in Fig. 1 (
c) As shown in (+) - (8a-1) - Reset switch contact (19-1) - Occupation detection relay (6a)
- (-) circuit is formed, and the riding detection relay (6a) is self-maintained via its contact (6a-1).

This hold is maintained until the reset switch (19) in the control room is operated.

Next, when it completes entering the car, the light beam is re-injected,
The boarding/alighting detection circuit (17) shown in FIG. 1(b) stops the excitation of the relay coil (17a), and the normally open contact for boarding/alighting detection (17a-1) shown in FIG. 1(C) opens. The normally closed contact for detection (17b-1) is closed, the normally open contacts Ha-t) to (2a-8) for unoccupied detection shown in FIG. 1(b) are opened, and the normally closed contact for unoccupied detection (2b -1), (2b-2) and (2b-3) are closed.

Then, as shown in FIG. 1(C), (+) - Normally open contact (6a-2) of the occupancy detection relay - Normally closed contact (2b-3) for unoccupied detection
) - Normally closed contact for boarding/exiting detection (L7b-1) - Normally closed contact for door opening/closing detection (18b-2) - Reset switch contact (
19-2) - Ride end memory relay (7a) - (+) circuit is formed, (+) - Ride end memory relay normally open contact (7a-1) - Reset switch contact (19-2) -
It is self-held by the ride end memory relay (7a) - ('') circuit until the reset switch (I9) is operated (
7a-1) Self-maintained by a circuit.

Therefore, the normally open contact (7a
-2) is in a closed state, (+) - normally open contact for boarding/exiting detection (7
a-2) -(27b-1)-Door control circuit (II)-
(-) circuit is formed and the door is forcibly closed by the door control circuit (8)-.

Even if the door open button (26) inside the car is pressed while the door is closed, it becomes invalid and the door will not open, and the normally closed contact for detecting getting on and off (
7b-2) opens, the (+) shown in FIG. 1(C) - Driving suspension changeover switch (29) - Normally closed contact for getting on/off detection (7b-2) - Driving suspension command circuit (9) - (−
) is no longer formed, and the operation stop command circuit (9) stops operation.

Then, a circuit of (+) - normally open contact for boarding/alighting detection (7a-3) - alarm device (1,0) - (-) is formed, so if the boarding is from the alarm device (10) in the security room or from the crime floor. Notify that a passenger has been captured.

In the above explanation, after boarding from the crime floor, it is easy to set the operation to a suspended state, or to switch to exclusive operation, such as forced operation to a specific floor, after boarding from the crime floor.

Moreover, although blocking and re-entering the light beam of the optical sensor was used to detect entry into the car, the present invention is not limited to the above-mentioned optical sensor, but can also be implemented using an unoccupied car detection circuit or the like.

Although the above embodiment has been described as a sequence using a relay, it is a programmable control. It is also possible to perform sequence control using -ra or the like.

[Effects of the Invention] As described above, according to the present invention, a car carrying a person is not stopped when going to a crime floor where a crime has been detected, so that an acid elevator user may accidentally go to a crime floor. The effect has been that it can prevent people from entering.

In addition, if the hall call button on the crime floor is pressed, an unmanned car will be run on that floor, the car will stop on the crime floor, and as soon as a passenger gets on board, the car will be forcibly closed, and the door will be forced to close. Once the elevator has stopped operating, only the passengers who boarded on the crime floor can be captured, reducing the chance of capturing general passengers and criminals in the same car, and safely capturing only criminals who are in a hurry to leave. The effect has been that the probability of doing so has been greatly improved.
