Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator warning system that utilizes a portable radio.

In recent years, crimes such as being attacked or threatened by robbers in the elevators installed in high-rise buildings such as J and I have occurred, and this has become a social problem.

Normally, elevators are equipped with alarm equipment such as communication devices and emergency bells, but this is the case! When 1 occurs, it is not always possible for the victim to operate the alarm equipment in order to prevent the intimidator, and there is a risk that the alarm equipment may not function effectively.

Therefore, there is a method of installing a television camera inside the elevator and remotely monitoring the images inside the elevator in a monitoring room, or forcing the elevator to stop at each floor for a predetermined period of time, for example, after 10 p.m. until 4 a.m. the next morning. A method has been proposed in which the release of the teacher gives the person an opportunity to escape from the intimidator.

However, in such facilities, unless the manager monitors the images from the television camera all day long in the monitoring room, he or she cannot grasp the situation inside the elevator, and there is a risk that an incident may be overlooked. Ta.

Furthermore, if the elevator is forced to stop at each floor after a predetermined time, there is a problem in that a user who uses the elevator from the first floor to the top floor takes time to reach the desired floor.

The present invention has been made in view of the problem described in -1-, and allows the victim to easily and reliably transmit an abnormality signal without being detected by the intimidator, control the elevator, and reliably display a warning. The purpose is to provide an elevator warning system.

In order to achieve this object, the present invention receives an abnormal signal from a wireless transmitter carried by a victim in a receiving section, outputs it to a control section, and controls the elevator based on the control signal from the control section. This is the first step to display an alarm on the alarm unit.

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is an overall configuration diagram showing an embodiment of the present invention.

First, to explain the configuration, 18 is an elevator, 1 is a portable transmitter that wirelessly transmits an abnormal signal by manual operation when an incident occurs, and 2 is a circuit section installed inside the elevator 18. , a receiving unit 3 that identifies and receives the abnormal signal and address from the transmitter 1, a position signal output unit 4 that outputs an elevator position signal, and a destination floor that outputs a destination floor signal indicating the user's destination. It includes a signal output section 5, a called floor signal output section 6 that outputs a call signal indicating an elevator call, and an alarm section 7 that issues an alarm by sounding a buzzer or the like. 8
is the control unit, which is installed in a monitoring room, etc. outside the elevator.
The operating state of the elevator 18 is constantly monitored by receiving information from the position signal output section 4, destination floor signal output section 5, and called floor signal output section 6, and when an abnormality signal from the reception section 3 is input, , controls the operation of the elevator 18 and operates the alarm unit 7. Reference numeral 9 denotes a drive unit equipped with a motor, etc., which raises and lowers the elevator and opens and closes the doors based on control signals from the control unit 8.

10 is a display section which inputs signals from the control section 8 and displays the operating status of the elevator 18. Reference numeral 19 denotes an operation section, which includes a recovery switch and the like that can be operated by a manager to recover from an abnormal situation when event A'1 occurs.

Next, the configuration of the transmitter 1 will be explained. Reference numeral 11 designates a power supply unit equipped with a battery, 12 a switch for manual operation, and 13 an oscillation unit that oscillates at a predetermined frequency.Power is supplied to the oscillation unit 13 by operating the switch 12 when an incident occurs. 14 is an address setting section, in which a predetermined address determined by the elevator is set. 15 is a modulation section;
When the oscillation signal from the oscillation section 13 is input, it is modulated based on the address code of the address setting section 14 and sent to the transmission section 16.
Output to. The transmitter 16 wirelessly transmits the abnormal signal modulated based on the address code via the antenna 17. The length of the antenna 17 can be shortened by using microwaves as the abnormal signal, and since the transmitter 1 is used in the elevator 18, the propagation distance of the abnormal signal is only a few meters, and the output wattage can be reduced. Since the transmitter 1 can be set at a lower value, the configuration of the transmitter 1 can be made small and portable.

FIG. 2 is a flowchart 1 showing the control operation of the control section 8 in FIG. The operation of the present invention will be explained with reference to the flowchart of FIG.

For example, if an elevator user uses the elevator from the 1st floor to go to the 6th floor, and is threatened after the elevator door is closed by a blackmailer who boarded the elevator from the 3rd floor, the elevator user will not be able to detect the threat. The abnormality signal is transmitted wirelessly by operating the switch 12 of the portable transmitter 1 to prevent the abnormality from occurring.

Block a determines whether or not an abnormal signal is received.
When the abnormality signal is input, the process proceeds to block b, where it is determined based on the information from the position signal output section 4 that the position of the elevator at the time of occurrence of the incident is between the third and fourth floors. Block C identifies that the destination floor, which is the user's destination, is the 6th floor based on the information from the destination floor signal output unit 5, and in consideration of the position identification in block b, the elevator is ascending. determine something. In block d, it is determined whether there is a called floor signal indicating an elevator call from another user, and if there is no call from another user, the process proceeds to block e. In block e, it is determined whether the person has reached the nearest floor, that is, the fourth floor, and when the fourth floor is reached, the process proceeds to block 1, and the threatened person escapes from the blackmailer by forcibly opening the elevator door. can.

Further, in block d, if there is a call for an elevator from another user on the second floor, for example, the process proceeds to block f, where it is determined whether the called floor is in the direction of travel of the elevator. Since the elevator is ascending and is located between the third and fourth floors, and the called floor is the second floor, the process proceeds to block 9.

In block q, the nearest floor is 41i1! Until reaching point i, the process returns to block f and checks whether there is a calling floor signal from the direction in which the elevator is moving. If no new calling signal is obtained, the process proceeds from block Q to block h. The driving unit 9 is operated to cause the elevator to descend in the opposite direction to the traveling direction, that is, toward the second floor, and stop at the called floor, that is, the second floor. In block i, by opening the elevator door, the threatened building can call the elevator and ask other users who are waiting to help. In block j, a buzzer 7 is sounded to alert passersby who are passing by to the occurrence of an abnormal situation.

The block determines whether there is a recovery operation or not, and by operating the operation section 19 in the monitoring room, it advances to the block color, turns off the buzzer of the alarm section 7, and stops the alarm.
let

In block 9 of Fig. 2, if there is a called floor in the opposite direction to the direction in which the elevator is moving, the elevator should be stopped at the nearest floor and the door should not be opened. However, in a high-rise building or high-rise residential building, if the nearest floor and the called floor are more than a predetermined number of floors in front of each other, the door is opened at the nearest floor without going to the called floor in the opposite direction. However, a warning may be issued.

Further, the receiving section 3 may be provided with a switching means that operates upon receiving an abnormality signal, and the switching means may be sent to a security company or the like to notify the occurrence of an abnormal situation.

As explained above, according to the present invention, when an elevator user is threatened by a blackmailer in the elevator, he or she can easily operate a portable wireless transmitter without being noticed by the blackmailer. Moreover, an abnormal signal can be reliably transmitted.

In addition, when an abnormal signal is sent, the elevator is stopped at the called floor, that is, the floor where someone is definitely waiting, and the door is opened, allowing the threatened person to ask the person waiting for help. can be done.
