The present invention relates to a technology for protecting passengers in an elevator from criminal acts. In particular, in a passenger elevator equipped with a closed circuit, a plurality of elevators are selectively monitored using a single monitor, and a passenger in an elevator When requesting a crime prevention, the monitoring camera of the elevator and the monitor installed in the disaster prevention room are automatically connected.If it is determined that the culprit is on board, the door of the elevator is closed and returned to the desired floor to be suitable for arresting the culprit. It relates to an anti-theft operation device and method of an elevator.

Recently, criminal acts in elevators have emerged as a social problem.

First, a means of attaching a treble sensor to the inside of a car and then suggesting a means of detecting a scream through the treble sensor and performing a predetermined crime prevention operation in case of a crime is performed. There is a fault becoming impossible.

Secondly, a means of stopping the stop at each floor while driving to the destination floor by suggesting a security operation switch function at a specific time such as midnight in a disaster prevention room is proposed, which may cause inconvenience to passengers using an elevator. Accompanied by this, it is possible to expect the effect on the psychological prevention of the criminal act, but there is a deficiency in which the criminal act itself cannot be sufficiently effective.

Third, a means of inducing a psychological security effect by installing an observation window on the landing door and the car-door so that the inside of the car can be seen from the outside is difficult. Moreover, there is a flaw in which people around cannot expect full effects unless they intentionally control the car interior.

Fourth, each camera is installed on each car ceiling to observe the means of using the closed circuit, that is, inside the car, and the camera is connected to each monitor installed in a separate service room. A means of observing the interior has been proposed, which is more effective than other means of security operation, but when applied to a large apartment complex or a large building in which several elevators are installed, it is expensive to install and more expensive to maintain and repair. There was a fault.

The present invention allows to monitor the various elevators selectively using a single monitor to solve the conventional defects, and when the passengers in the elevator requests a crime prevention operation to the monitoring camera and the disaster prevention room of the elevator Installed monitors can be connected and monitored automatically, and when it is determined that the culprit is aboard, it is designed to return to the reference floor in a state where the door of the elevator is closed and to arrest the culprit, which will be described in detail with reference to the accompanying drawings. do.

First, referring to FIG. 3, when a passenger boarding a car 100 presses an emergency call button EBT to request a crime prevention driving, an interphone main machine INTM installed in the disaster prevention room 200 and the corresponding car 100. Interphones (INTS) installed in the interior are connected to each other, the manager and the passenger is available for a call, which will be described as follows.

When the passenger in the car 100 presses the emergency call button (EBT) to request a crime prevention operation, the power terminal (+) → the contact point (a ₂ , c ₂ ) of the hook switch (HSW) → the oscillator 212C → Light emitting diode (LED) for crime prevention request display → contact point (c ₂ , a ₂ ) of the selected position (SELSW) → emergency call button (EBT) → intercom call (INTS) transmission / reception section 11A, 111B → The power is supplied through the power terminal (-), the light-emitting diode (LED) for the security operation request display of the interphone parent (INTM) installed in the disaster prevention room is turned on, a warning sound is generated in the oscillator (212C).

Accordingly, when the manager in the disaster prevention room 200 recognizes that the current crime prevention operation is requested and pulls out the handset HS, thereby the power terminals (+) and (-) contact the contacts (a ₁ ) of the hook switch (HSW). , b ₁ ), (a ₂ , b ₂ ) are respectively connected to the transmitter 212A and the receiver 212B of the interphone master (INTM), when the manager presses the interphone magnetic selection switch (SELSW), The transmitting and receiving terminals T and R of the transmitting unit 212A and the receiving unit 212B of the interphone main unit INTM are the contacts b ₁ , a ₁ , and b ₂ , a ₂ of the selection switch SELSW. Are connected to the transmitters 11A and 111B of the interphone device INTS installed in the car 100, respectively, so that passengers in the car 100 and the manager of the disaster prevention room 200 can talk to each other. Will be.

On the other hand, Figure 4 shows an application example of the present invention when four elevators are installed in one building, the call and monitoring process according to this will be described as follows.

First, the process of talking between the manager and the passenger through the interphone main phone (INTM) installed in the disaster prevention room 200 and the interphones 8 INTS _1- INTS ₄ ) installed in each car 100 is as described in FIG. 3. That is, the manager recognizes that the passenger presses the emergency call button (EBT) respectively installed on the In-the-Phone (INTS), and switches the corresponding selection switch among the interphone magnetic selection switches (SELSW ₁ -SELSW ₄ ) or the administrator arbitrarily selects the interphone. One of the self-selecting switches (SELW ₁ -SELSW ₄ ) can be switched to talk to the passenger of the corresponding machine.

In order to manually monitor the inside of the car 100 through the monitor 211 for the security operation, the administrator selects the manual mode by switching the manual / automatic selection switch (SW ₀ ) to the manual terminal (m) In order to select the camera of the exhalation unit to be monitored by switching the camera selection switch (SW ₁ -SW ₄ ) again, for example, if you want to monitor unit 3, the switch (SW _1- SW ₄ ) of the switch ( When SW ₃ ) is turned on and the remaining switches SW ₁ , SW ₂ , and SW ₄ are turned off, the camera CM3 of Unit 3 switches from the on contact of the switch SW _{3 to} the off contact of the switch SW ₂ . Since it is connected to the monitor 211 through the off contact of (SW ₁ ) and the manual contact (m) of the manual / automatic selection switch (SW ₀ ), the administrator can monitor the inside of the unit 3 through the monitor 211. It becomes possible.

In order to automatically monitor the corresponding unit by accepting the passenger's request for crime prevention, the administrator selects the automatic mode by switching the manual / automatic selection switch (SW ₀ ) to the automatic terminal (a). If any of the passengers on board ~ 4 outputs a specific signal in order to request a crime prevention operation, for example, pressing the door closing button and the destination floor button at the same time, the crime prevention operation command relay is driven to operate the relay contact point. The camera of the corresponding unit is connected to the monitor 211. For example, when a passenger in the second unit presses the door closing button and the destination floor button installed in the car at the same time to request a security operation, the crime prevention command relay is driven. Contact A22 of the relay is short-circuited (on), and the remaining contacts A21, A23, and A24 are opened (off). (A 22) → b contact (A21 ') → the automatic contact (a) of the manual / automatic selection switch (SW ₀ ) is connected to the monitor 211, so the administrator can open the inside of the unit 2 through the monitor 211. You can monitor it.

As described above, when it is determined that there is a passenger suspected to be the culprit among the passengers who have boarded through the interphone and monitoring process, the criminal is arrested by driving the corresponding unit to a specific floor. It will be described in detail.

When a passenger checks the surroundings of a car 100 and asks for a crime prevention driving because there is a suspicious person among the passengers who are on board, the suspicious person should not notice the present invention. By pressing the closing button XCL and the destination floor button XCB at the same time, a crime prevention operation was requested.

For example, when the passenger on board presses the door closing button (XCL) and the 10th floor destination floor button (XCB10) at the same time to request a crime prevention driving, the crime prevention driving registration relay (ZXB10) is driven to contact a of the relay (ZXB10). Since the switch ZXB10a ₁ is short-circuited, power is supplied to the destination floor relay ZB10 through the switch ZXB10a ₁ and the b contact switch XPOSI ₁₀ of the position detection relay that opens when the floor is reached. The ZB10 is driven, and this state is held by the switch ZB10a ₁ of the destination floor relay ZB10 and held until it reaches the 10th floor.

Then, the switch ZB10a ₂ of the destination floor relay ZB10 is short-circuited to drive the security operation recognition relay ZBB. As a result, the switch ZBB _a1 of the relay ZBB is short-circuited. C) The crime prevention operation command relay A is driven, thereby shorting the switch A ₁ of the relay A in FIG.

Accordingly, the alarm sound is generated from the oscillator 212C installed in the disaster prevention room 200 in the same manner as when the emergency call button EBT is pressed, and the LED for illuminating driving request is turned on so that the administrator can recognize the fact. It becomes possible to recognize, the interphone of the corresponding unit and the interphone of the disaster prevention room 200 becomes a callable state, the camera of the unit is connected to the monitor 211 as described in FIG. Can be monitored.

Accordingly, the fact that the criminal driving the security driving indication lamp (BBLP) flickered and installed as shown in FIG. 2 by the short circuit of the security driving recognition relay (ZBB) switch ZBB _a2 is currently in progress In other words, you are aware that you are being watched, which can help prevent crime.

In spite of the above warning, if the manager observes the criminal's dynamics through the monitor 211 and the interphone, and it is considered that there is a crime, it is possible to lead the elevator to the specific floor and arrest the criminal. for presses the fourth-degree arrest switch (PACK ₁ -PACK ₄₎ Roundup switch (for example, one layer arrest switch (PACK ₁₎₎ of the desired layer on the way.

Accordingly, in FIG. 6, the criminal arrest switch (XPACK) is short-circuited, so the arresting relay (ZPACK) is driven, and the b contact switch (ZPACK _a1 ) of the arresting relay (ZPACK) and the door control relay (ZHBC) ( Since ZHBC _b1 ) is self-maintaining, the arresting relay (ZPACK) remains on until it reaches the first floor and the door is opened. As a result, the switch of the arresting relay (ZPACK) (ZPACK _a1 ) is Since the reference layer return relay is driven by a short circuit, the car 100 returns to the first floor, which is the reference layer.

By the above process, once the car 100 is completely returned to the reference layer (for example, the first floor), the b contact switch ZPACK _b1 of the arresting relay ZPACK is kept open so that the call registration relay is maintained. The car call registration relay and the door open relay are not driven by any command, and the criminal cannot escape from the car 100.

However, if the car 100 enters the management operation specific signal while the car 100 is completely returned to the first floor, for example, pressing the call registration button (△ or ▽) installed on the hoistway of the first floor for 5 seconds or more, the call button contact (XHB1) Power supply to the timer relay ZHBT for 5 seconds or more through the switch ZPACK _{a2 of the} detection relay ZPACK, the switch XPOSI ₁ of the position detection relay, and the switch Z ₁₀ of the relay driven when the car is stopped. Is supplied, and the timer relay ZHBT is driven.

Accordingly, the switch ZHBT _a1 of the timer relay ZHBT is shorted to drive the door control relay ZHBC, and the switch ZHBC _a2 of the door control relay ZHBC is shorted to drive the door opening relay. As a result, the door is opened so that the criminal can be arrested.

At this time, since the b contact switch ZHBC _b1 of the door control relay ZHBC is opened by driving the door control relay ZHBC, the self-maintaining state of the parking relay ZPACK is released, thereby preventing the operation mode. Is released and it returns to normal operation mode.
