Abstract

PURPOSE:To surely judge a person in a cage and prevent a crime by detecting a passenger in a cage waiting while the door is closed and no direction is indicated during a nonbusy period, performing communication via announcement, and judging whether the passenger is a suspicious person or not based on the response. CONSTITUTION:A CPU 11 in a control board 1 judges whether an elevator is busy or not based on the number of calls from an operation board 5 and passenger buttons 21-24 and detects the presence of a passenger in a cage 4 waiting while the door is closed and no direction is indicated during a nonbusy period based on the state of a drive device 2 and the weight signal from a weighing device 7. When there is a passenger, such communication as the operation method is performed with the passenger in the cage 4 via an announcement device 6. The response from the passenger is judged to determine whether the passenger is a suspicious person or not. If the passenger is judged as a suspicious person, an alarm or a report is sent via an input/output device 15. The presence of the suspicious person is reported to a monitoring center from the announcement device 6 or a serial input/output device 14 via a communication device 8 and a telephone line 9.

Description

[Detailed description of the invention]

0001

[Field of Industrial Application] This invention relates to an elevator crime prevention device and method for determining a suspicious person who is hiding in an elevator car and who may commit a crime, and in particular, relates to an elevator crime prevention device and method that can be used reliably without impairing normal usage functions. The present invention relates to an elevator crime prevention device and method that can detect suspicious persons and prevent crimes.

0002

[Prior Art] Generally, an elevator car becomes a closed room when the door is closed, so that even if a general passenger is attacked and harmed by another passenger inside the car, he or she cannot seek help from outside. I can't. Therefore, in order to prevent such situations, various crime prevention devices have been proposed in the past.For example, a crime prevention device that forcibly stops the car at each floor while an alarm buzzer sounds when a security button inside the car is pressed. or,
There are security devices that limit the number of passengers allowed in the car to one person by pressing the security operation button at the landing.

FIG. 6 is a block diagram schematically showing the main parts of a conventional elevator security device, which is disclosed in, for example, Japanese Patent Publication No. 63-27266. In the figure, 3
1 is a landing button installed at the landing on each floor; 32 is a destination button installed in the car; 33 is an integrator that adds up the number of call inputs within a certain period of time obtained from the landing button 31 and the destination button 32; 34 is an integrator This is a predetermined value signal corresponding to a predetermined number of calls that serves as a criterion for determining off-peak times.

35 is the number of calls for a certain time from the integrator 33 applied to input A and a predetermined value signal 34 applied to input B.
It is a comparator that compares input A (number of calls) ≧ input B
(predetermined value signal), the output becomes "H", and the input A<
When the input is B, the output becomes "L".

36 is an output detection relay that is energized when the output of the comparator 35 becomes "H"; 36b is the output detection relay 3;
6 is a normally closed contact, 37 is a normally open crime prevention operation button installed at the landing, 38 is a normally open contact that closes when a start command is given when the car is running, and 39 is a crime prevention operation button when energized. 39a is a normally open contact of the crime prevention command relay 39, and (+) and (-) are the anode and cathode of the DC power supply. Normally closed contact 36b of output detection relay 36,
The crime prevention operation button 37 and the crime prevention command relay 39 are inserted in series between the DC power supplies (+) and (-), and the normally open contact 38 of the start command relay (not shown) is the normally closed contact 36b.
The normally open contact 39a of the crime prevention command relay 39 is connected in parallel to the crime prevention operation button 37.

Next, the operation of the conventional elevator security device shown in FIG. 6 will be explained. When a passenger presses the hall button 31 or the destination button 32, the output signal representing the call of each button becomes "H", and the number of calls is displayed in the integrator 33.
It is calculated by The comparator 35 determines whether the number of calls within a certain period of time is greater than or equal to the predetermined value signal 34.
If it is 4 or more, it outputs an "H" signal indicating that it is not a quiet time, energizes the output detection relay 36, and closes the normally closed contact 3.
Open 6b. Therefore, during the daytime when there are many users, the normally closed contact 36b
Since this is open, even if the crime prevention operation button 37 is pressed and closed, the crime prevention command relay 39 will not be energized and the crime prevention operation state will not be entered.

On the other hand, during the off-peak hours at night, the number of elevator users decreases, so the number of calls within a certain period of time becomes less than the predetermined value signal 34, and the comparator 35 outputs a signal indicating the off-peak hours.
L" signal is output, the output detection relay 36 is deenergized, and the normally closed contact 36b is closed. Here, when the security operation button 37 is pressed and closed, a circuit is formed from the anode (+) of the DC power supply to the cathode (-) of the DC power supply via the security operation button 37 and the normally closed contact 36b. , crime prevention command relay 39
is energized. At the same time, the normally open contact 39a is closed, so the crime prevention command relay 39 maintains its energized state even after the security operation button 37 is released.

In this state, when a start command is issued to the car, the start command relay is energized and the normally open contact 38 is closed. Therefore, even if the number of calls increases while the car is running and the normally closed contact 36b is opened due to the energization of the output detection relay 36, the energized state of the crime prevention command relay 39 is self-maintained. That is, if the security driving button 37 is pressed during quiet hours at night,
Once the crime prevention driving state is entered, this crime prevention driving state is self-maintained.

[0009] In this manner, by operating the security operation button 37 at the landing during off-peak hours, it is possible to set the car to a security operation state by, for example, allowing only one passenger to board the car. However, if a suspicious person is hidden in the car, it cannot be detected from the landing, so no crime prevention measures can be taken.

[0010] Therefore, crime prevention devices for the purpose of detecting a suspicious person inside a car have also been proposed. For example, although not shown, Japanese Patent Application Laid-Open No. 2-75582 describes an elevator security device that outputs an abnormal signal when there is no car call and a passenger is present when the car door is closed. In this case, the weight detecting means detects the presence of a passenger in the car, the door open/close state detecting means detects the closed state of the door, and the car call detecting means detects the state of no car call.

[0011] However, even with this security device, an abnormal signal is output if a normal user presses the destination button in the car too late when boarding the car, which not only makes passengers feel uneasy but also causes abnormal signals to occur frequently. This may result in wasted effort.

0012

[Problems to be Solved by the Invention] As described above, with the conventional elevator security device, when the security operation button at the landing is used, it is impossible to discover a suspicious person hiding in the car, If it were possible to detect a suspicious person inside the car, the system would malfunction due to delays in car call operations by general passengers, resulting in poor reliability and unnecessary effort.

[0013] This invention was made in order to solve the above-mentioned problems, and it is possible to reliably identify a suspicious person hiding in a car without impairing normal elevator functions, and to prevent crimes. An object of the present invention is to obtain a crime prevention device and method for an elevator that can prevent theft.

[0014]

[Means for Solving the Problems] A crime prevention device for an elevator according to the present invention includes a quiet time determining means for determining whether or not it is a quiet time based on the number of calls registered within a unit time, and a non-directional door during a quiet time. A passenger detecting means for detecting whether or not there is a passenger in a car waiting to be closed; an announcing means for communicating with the passenger through an announcement; a response determining means for determining a response from the passenger to the announcement; and a response determining means. The vehicle includes a suspicious person determining means for determining whether or not the passenger is a suspicious person based on the determination result of the means, and a communication means for generating an alarm or report when the suspicious person determining means determines that the passenger is a suspicious person. It is something.

[0015] Furthermore, the crime prevention method for an elevator according to the present invention includes the steps of determining whether or not it is a quiet time based on the number of calls registered within a unit time, and determining whether or not the car is waiting for the non-directional door to be closed. a step of determining whether there is a passenger in the car waiting to close the non-directional door; and a step determining whether there is a passenger in the car waiting to close the non-directional door during off-peak hours. The method includes the steps of announcing the operating method, determining whether the passenger is a suspicious person based on the response to the announcement, and issuing an alarm or notification when the passenger is determined to be a suspicious person.

[0016]

[Operation] In this invention, when it is determined that it is a quiet time based on the call occurrence situation, if a sensor such as a scale switch detects that there is a passenger in the car waiting to close the non-directional door, the elevator operation method etc. The passenger is instructed in an interactive manner through an announcement, and based on the response at that time, the step in the interactive manner is advanced to determine whether or not the passenger is a suspicious person.If it is determined that the passenger is a suspicious person, an alarm or report is issued.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of an elevator security device according to the present invention. In the figure, 1 is a control panel, which includes a CPU 11, a ROM 12 and a RAM 13 belonging to the CPU 11, and a serial input/output device 14 and an input/output device 15 connected to the CPU 11 via a bus.

2 is a drive device that includes a motor and a hoist and raises and lowers the elevator car; 3 is a counterweight that is attached to the drive device 2 via a wire; 4 is a counterweight that is attached to the drive device 2 so as to oppose the counterweight 3; 5 is a control panel inside the car 4 equipped with a door opening button, a destination button, etc., and 6 is a speaker and microphone for outputting an alarm buzzer sound and a voice message. 7 is a scale device that detects the presence or absence of passengers in the car 4 by weight. Drive device 2, operation panel 5
, the announcement device 6 and the weighing device 7 are connected to an input/output device 15 in the control panel 1.

8 is a serial input/output device 14 in the control panel 1
9 is a communication device connected to the communication device 8 and the monitoring center (
(not shown). Numerals 21 to 24 are landing buttons for each floor assuming a four-story building, for example, and are connected to the input/output device 15 in the control panel 1.

The CPU 11 in the control panel 1 has off-season determining means for determining whether or not it is an off-peak time based on the number of calls from the operation panel 5 (destination button) and the landing buttons 21 to 24, and non-directional door control in off-peak times. Passenger detection means detects whether or not there are passengers in the car 4 which is waiting to be closed based on the state of the drive device 2 and the weight signal from the weighing device 7; an announcement means for communicating with the passenger through announcements, a response determination means for determining a response from the passenger to the announcement, a suspicious person determination means for determining whether or not the passenger is a suspicious person based on the determination result of the response determination means; A communication means for generating an alarm or notification via the announcement device 6 or the communication device 8 when it is determined that the person is a suspicious person.

Each means in the CPU 11 is configured by a program stored in advance in the ROM 12, and the results of calculations etc. during the operation of each means are stored in the RAM 13. Further, the serial input/output device 14 is connected to the CPU 11.
and the communication device 8, and the input/output device 15
performs information exchange between the CPU 11, the drive device 2, and the operation panel 5. Information exchange by the input/output device 15 includes voltage level conversion, AD conversion, serial/parallel conversion, and the like.

Next, the normal operation of the embodiment of the elevator security device according to the present invention shown in FIG. 1 will be explained. For example, when car 4 is on the second floor waiting for the non-directional door to close,
When a passenger presses the hall button 21 on the first floor, a hall call signal for the first floor is input to the CPU 11 via the input/output device 15, and the CPU 11 drives the drive device 2 according to a well-known operation program to move the car 4. Run it in a descending direction, stop at the first floor, and open the door. Next, when the passenger gets into the car 4 and presses the desired destination button on the operation panel 5, the car call is input to the CPU 11 via the input/output device 15, and after closing the door, the car 4 is called by the same operation program. will run to the floor specified by the destination button.

Next, the crime prevention operation of the embodiment of the present invention shown in FIG. 1 will be explained with reference to the flowcharts shown in FIGS. 2 to 4. 2 shows the main program, FIG. 3 shows the suspicious person determination program, and FIG. 4 shows the suspicious person processing program. First, in the main program in Figure 2, CP
U11 detects the states of the drive device 2, operation panel 5, scale device 7, and hall buttons 21 to 24, and executes the following determination steps S1 to S3.

That is, it is determined whether or not the car 4 is waiting with the door closed in no direction (step S1), and if the car 4 is waiting with the door closed in no direction, it is determined whether or not there is a passenger in the car 4. (Step S2), and if there are passengers at this time, it is determined whether it is a quiet time based on the number of calls registered within a unit time (Step S3). For example, in step S3, the determination is "NO" because there are many passengers during daytime congestion;
During the off-peak hours at night, there are very few customers (the number of calls within a unit time is less than a predetermined value), so the determination is ``YES'', and the off-peak hours can be detected.

[0025] In each of the above steps S1 to S3, "N
If the determination is ``O'', the process skips the other steps and returns, and steps S1 to S3 are repeated. In addition, if the determination is ``YES'' in all steps S1 to S3, and it is determined that there is a passenger in the car 4, which is waiting with the door closed and has no direction at a quiet time, the suspicious person determination program (FIG. 3) is called. (Step S4).

In the suspicious person determination program shown in FIG.
First, the CPU 11 transmits a command via the input/output device 15, and the announcement device 6 announces the operation method, for example.
"Please press the desired destination button" is announced (step S10). Then, in response to this announcement, it is determined whether or not an operation has actually been performed (step S1).
1) If the passenger is operated, it is determined that the passenger is a normal passenger and the process returns to the main program shown in FIG. 2. If the passenger is not operated, the process waits until a predetermined time elapses in step S12.

For example, if a confused passenger who is unfamiliar with elevators presses the destination button on the operation panel 5 within a predetermined time in response to the announcement in step S10, a car call signal is sent via the input/output device 15. , it is detected that the passenger has performed a response operation, and the process proceeds to step S11.
Return to the main program. At this time, since the car call has already been registered and the running direction exists, the determination in step S1 is "NO", and the process returns to the normal state.

On the other hand, the passenger in the car 4
If no response operation is performed after a predetermined period of time has elapsed in response to the announcement, the next response method is announced, for example, "Please press the door open button" (step S13).
). Then, in response to this announcement, it is determined whether or not the door opening operation was actually performed (step S14), and if
If the passenger is operated, it is determined that the passenger is a normal passenger and the process returns to the main program shown in FIG. 2. If the passenger is not operated, the process waits until a predetermined period of time has elapsed in step S15.

For example, if a passenger in car 4
If the door open button on the operation panel 5 is pressed within a predetermined time in response to the announcement No. 3, the response operation by the passenger is detected as described above, and the process returns to the main program from step S14. Then, in step S1, since the door is open, a "NO" determination is made, and the process returns to the normal state.

[0030] On the other hand, the passenger in the car 4
If no response operation is performed within a predetermined period of time to the announcement, the suspicious person processing program (FIG. 4) is called (step S16).

In the suspicious person processing program shown in FIG.
First, the CPU 11 generates an alarm or notification via the output device 15 (step S20). That is, the announcement device 6 or alarm devices such as a buzzer or indicator light in the manager's room (
(not shown) to generate an alarm, or the serial output device 14 calls the monitoring center via the communication device 8 and telephone line 9 to report the presence of a suspicious person.

Thereafter, it is determined whether there is a passenger in the car 4 (step S21), and the door is kept open until it is determined that there is no passenger (step S22). That is, once it is determined that the person is a suspicious person, the door remains open until there are no more passengers in the car 4, so it becomes impossible for the person to hide inside the car 4. During this time, if the passenger leaves the car 4, or if the manager who received the alert or the person in charge at the disaster prevention center or monitoring center who received the report rushes to take the passenger out of the car, a "NO" determination will be made in step S21. Then, the process returns to the main program shown in FIG. 2, and a "NO" determination is made in step S2, returning to the normal state.

[0033] In this way, when it is determined that it is a quiet time based on the call occurrence situation (step S3) and it is determined that the non-directional door is on standby (step S1), the sensor such as the scale switch 7 detects the When the presence of a passenger is detected (step S2), instructions such as how to operate the elevator are given in an interactive manner through an announcement (step S10), and the steps in the interactive manner are advanced based on the response at that time (step S13).
If the person is determined to be a suspicious person, an alarm or report can be issued (step S20).

Therefore, even if a suspicious person is hidden in the car 4, it can be determined and found with certainty.At the same time, passengers who are unfamiliar with elevators can be guided on how to operate the elevator, so they can feel at ease. The user can use the elevator and will not be erroneously judged as a suspicious person. Further, during the daytime when there are many users, unnecessary announcements are not made, so normal elevator functions are not impaired.

In the above embodiment, in the suspicious person processing program, the door is held open (step S22) until there are no passengers from the car 4;
may be omitted. In this case as well, until the suspicious person presses the door open button and exits the car 4 or is taken out by the manager etc., "Y
ES" continues, the program does not return to the main program shown in FIG. 2 and return to the normal state.

Furthermore, although suspicious persons are excluded by the step S22 of keeping the door open, if the suspicious person is to be arrested, for example, as shown in FIG. It is desirable to insert FIG. 5 is a flowchart showing a suspicious person processing program of another embodiment of the elevator crime prevention method according to the present invention.

In FIG. 5, first, in order to warn of the reporting status, an announcement is made, for example, "If you do not press the door open button and go outside, the monitoring center will be notified" (step S2
3). Then, until a predetermined time elapses (step S2
4) Execute the passenger presence/absence determination step S21, and if the suspicious person comes out of the car 4 within a predetermined time, the determination in step S21 is "NO" and the normal state is restored.

[0038] If a suspicious person continues to leave car 4 after a predetermined period of time has elapsed,
If the user is inside, the door is kept closed, the elevator operation is stopped, and car call and hall call registration and door opening operations are all disabled (step S25). This prevents the suspicious person from leaving the cage 4. Subsequently, the alarm or notification step S20 is executed, and the staff or manager of the monitoring center responds.
Suspicious persons can be easily arrested.

In each of the above embodiments, explanations have been made on the assumption that the determination function of the CPU 11 is reliable. Good too. That is, the attendant or manager can re-determine whether or not the passenger is a suspicious person by talking to the passenger in the car 4 via a direct communication system such as a telephone line and an intercom. Further, in this case, a function may be added that allows the person to return to the normal state by remote control from the monitoring center or by operating a switch in the manager's room when it is determined that the person is not a suspicious person through direct communication.

Furthermore, although the weighing device 7 is used to determine the presence or absence of passengers in the car 4, passengers may also be detected using infrared rays, image processing, or the like. Furthermore, it goes without saying that the suspicious person determination step based on the response to the announcement is not limited to two or three stages, but can be set to any number of stages.

[0041]
