Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator monitoring device capable of preventing crime in an elevator car.

[0002]

2. Description of the Related Art As an example of a conventional elevator monitoring device,
There are first, second, and third examples described below. The first example is a system in which a surveillance camera is provided in a car, the situation in the car is simply displayed on a surveillance monitor such as a surveillance room, and recorded by a video recording device.

A second example is a system in which an abnormality detecting sensor for detecting an abnormality in a car is provided, and after detecting the abnormality, the system is automatically notified to an external monitoring room. The third example is a system in which a device for tracking passengers in a car is provided, and a security control device is activated when a passenger performs abnormal behavior when using an elevator.

[0004]

The above-mentioned prior arts have the following problems. In the first example of the related art, when a crime occurs in an elevator car, there is a problem that a rescuer cannot respond immediately to passengers in the car just by a supervisor in a monitoring room watching the monitoring monitor. Occurs. Also,
If a criminal offense is not monitored by a watcher, it is impossible to know that the criminal act has been committed unless the victim passenger reports to the outside. Furthermore, even if the situation inside the car is recorded by the recording device, the security for passengers is not ensured only because the evidence of criminal activity is suppressed.

[0005] In the second conventional example, even if the police or the like are immediately reported, the criminal harms the passengers while reporting. In addition, when a criminal offense is not monitored by a watcher, it is not known that a criminal act has been committed unless a passenger who has suffered damage notifies the outside. Further, in the second conventional example, even when the number of passengers is one, the abnormality detection sensor detects abnormal behavior with respect to one passenger.
In addition, abnormal situations are detected even in situations that are not considered to be criminal acts. Therefore, there is a problem that the operation of the elevator is hindered due to erroneous detection or the like.

[0006] In the third conventional example, similarly to the first and second conventional examples described above, anomalies are detected in situations that are not considered to be criminal acts. Further, even when a large number of passengers get on and off the vehicle while the elevator car is open, there is a problem that the operation during the getting on and off is regarded as abnormal and erroneous detection occurs.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to solve the above-mentioned problems, and an elevator capable of accurately discriminating criminal acts, preventing criminal acts beforehand, and preventing criminal acts. A monitoring device is provided.

Is a human body detecting means provided at the landing for passenger detection, and when the processing apparatus 2 detects an abnormality in the car 1, it detects the presence or absence of a passenger at each landing. 20 is a door.

FIG. 2 is a block diagram showing the configuration of the processing unit 2, in which 21 is a CPU (central processing unit), 22 is a memory including a ROM and a RAM, and 23 is a display division control for in-car monitors. Means, 24 is voice synthesis control means, 25 is load control means, 26 is call control means, 27 is call control contact means, 28 is door control means, 29 is warning lamp control means, 30 is a human body detection for detecting passengers at the landing. Control means.

The operation and effect of the above configuration are as follows. That is, the CPU 21 determines whether or not the door 20 of the car 1 is being opened (step 101). If it is determined that the door is being closed, the CPU 21 outputs the signal from the load detecting means 15 in the car of the elevator. Load detection means 25
It is determined whether or not it is equal to or smaller than a predetermined amount (xkg) (step 102). The judgment in step 102 is for passenger 1
This is the case where only the load of a person is detected.

If it is determined in step 102 that the load detection signal is equal to or more than the predetermined amount (xkg), the reference tracking operation value (operation reference value: the value of the output level serving as the reference of the tracking monitoring camera operation detection means 7) A comparison process is performed between the current value and the value output from the tracking surveillance camera operation detecting means 7 (step 103). In step 103, if the value detected by the tracking surveillance camera operation detecting means 7 is smaller than the reference tracking operation value, the comparison process is performed as needed (step 10).
3: “NO”).

If it is determined in step 103 that the value is equal to or higher than the reference tracking operation value, the processing device 2, specifically, C
The PU 21 outputs a first abnormality detection signal (step 1).
04).

Since the first abnormality detection signal is output, the CPU 21 activates the voice synthesizing control means 24, outputs a warning message from the voice output means 4 in the car, and controls the voice synthesizing control means 24. At the same time
An audio signal is reported to a monitor room, a security company, a monitor 17 of the police or the like, or the external reporting means 13 via the video transmission reporting means 8 and the video receiving reporting means 9 included in the operation control means 14.

It is determined whether or not the signal (tracking operation value equal to or higher than the reference value) from the voice synthesis control means 24 has continued for a predetermined time (step 106), and it has been determined that the signal has continued for a predetermined time (step 106). In step 106, "YE
In the case of S ″), processing as shown in FIG. 5 is performed.

That is, after the second abnormality detection signal is output (step 301), the second abnormality detection signal (step 301) is displayed on the in-car monitor 6, and the in-car monitor division display means 23 is activated. Then, the display is switched to the monitor room screen display and the warning message screen display (step 302).

Thereafter, the call control contact means 27 is closed by the call control means 26, and the in-car communication means 5 is activated.
Surveillance camera 1 connected to the outside of the monitoring room and installed in the monitoring room
0 and the monitoring room monitor 11 by the monitoring room communication means 12
The passenger and the observer in the car 1 can talk while confirming the expression of the other party.

If a passenger is present at the landing, the car 1 is emergency stopped (step 303) to the floor where the passenger is located, and the door is opened (step 202). After elapse of the predetermined time y seconds (step 203), the door is closed and normal operation is started (step 204).

If no passenger is detected at the landing,
Emergency stop of car 1 to the nearest floor (step 20)
1). After the door is opened (Step 202), after a lapse of a predetermined time y seconds (Step 203), the door is closed and normal operation is started (Step 204).

If it is determined in step 106 that the signal has not continued for a predetermined time ("NO" in step 106), or in step 107
When it is determined that there are no passengers at the landing, processing as shown in FIG. 4 is performed.

Next, an embodiment corresponding to each claim will be described. <First Embodiment (corresponding to claim 1)> A first embodiment will be described with reference to FIGS. 1, 2, 3, and 5. FIG.
