Abstract

PURPOSE:To discriminate easily whether communication by an emergency button is mischief by constructing a monitor camera in such a way as to transmit static images in a cage to a storage device in a specified cycle and forming a monitor into divided image planes projecting the static images stored in the storage device successively. CONSTITUTION:When a passenger 9 in a cage 1 operates an emergency button 3, this detection is transmitted to an input signal generating part 42, where the image data of static images sent from a monitor camera 2 in a specified cycle is A/D converted, and this data is stored in the image memory of a storage device 44. The stored data is transmitted to an image regenerator 7 in a building manager room 6 though communication source 5. This data passes the contact (a) of a switching apparatus 71 and is inputted into a memory 81a, corresponding to the image plane 81 of a monitor 8, in an image regenerating memory 72. An output signal generating part 73 then controls a D/A converting part 74 to convert the data in the memory 72 to be outputted to the monitor 8. The static images sent out in the specified cycle are thus outputted to the divided image planes 82-84 of the monitor 8.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an elevator security monitoring system fK.

[Conventional technology]

Generally, elevators are equipped with a security monitoring device located inside the car and consisting of an emergency button and a monitoring camera. In the event of an emergency, passengers operate the emergency button in the car and communicate with the manager's office.
Meanwhile, in the manager's office, they communicate while looking at still images sent from surveillance cameras and deal with emergencies.

However, if a passenger operates the emergency button and then gets off the car even though it is not an emergency situation, there is no end to the mischief that can be caused to equipment inside the car. In such a case, even if the caretaker in the caretaker's room sees a still image in which no one is in the car, the possibility of a criminal accident cannot be ruled out, so he is dispatched as an emergency situation.

In order to eliminate this kind of waste, the time opening $1-238672
As described in the above publication, a system has been proposed that uses a car weight measuring sensor to detect the presence or absence of passengers and to identify abnormalities.

[The problem that the invention attempts to solve]

Conventional elevator security monitoring equipment is configured as described above, and even if the emergency button alert is not due to an emergency situation, but is due to a crime, the still image sent to the manager's room is extremely sensitive. The image is taken when the button is pressed, so even if the report is due to a prank by a passenger and the passenger then leaves the car, the manager will be dispatched to the car where there is no emergency. Must.

In addition, with the method of using a car weight measurement sensor, it is necessary to install a new one because it is not available in existing products, and it is difficult to install a measurement sensor that can identify light weights such as one passenger. Yes, it lacks practicality.

Here, it is possible to project it with a moving image,
It is expensive and difficult to popularize.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator crime prevention monitoring device that can easily determine whether a notification from an emergency button is an operation due to an emergency situation or an operation due to a mischief.

[Ninth means to solve the problem]

To achieve the above object, the present invention has a surveillance camera that displays the situation inside the rice basket as a still image when an emergency button is operated, and is configured to transmit the above-mentioned still image to a storage device at a predetermined period. The monitor device is characterized in that it has a split screen so that still images stored in the storage device are sequentially displayed.

[For production]

Since the elevator security monitoring device according to the present invention is configured as described above, when the emergency button for reporting an emergency situation in the car is operated, the surveillance camera takes still images of the inside of the car at a predetermined period. These still artists are then temporarily stored in a storage device and displayed one after another on a split-screen monitor. As a result, the manager not only sees a still image of when the emergency button was operated, but also displays the interior of the car in sequence on a split screen at a predetermined period afterward, allowing the manager to operate the emergency button and view the inside of the car, including the nine passengers. Since changes in the situation inside the cage can be observed, it is possible to identify mischief and eliminate unnecessary dispatch.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an overall configuration diagram of an elevator security monitoring device.

Emergency button 2 to report an emergency situation in car 1 and passenger 9
A surveillance camera 3 is provided which displays the situation inside the car 1 as a still image when the emergency button 2 is operated, and an image input device 4 having a storage device 44 is provided on the car 1.
is provided. In addition, on the manager's room 6 side, there is an image input device 4 and an image playback device 7 connected via a port ([5]).
A monitor device 8 is provided with one split screen 81 to 84.
is connected.

The configuration of the above-mentioned next image input device 4 will be explained with reference to FIG.

The emergency button 3 is connected to a detection section 41, and the surveillance camera 2 is connected to an input signal generation section 42 and an A/D conversion section 43, respectively. The input signal generating section 42 is connected to an A/D converter 43 and a storage device 44 consisting of an image storage memory including a communication section.

Next, the configuration of the artist playback device 7 will be explained with reference to FIG.

The communication line 5 is connected to a switch 71K, and transmits the image data transmitted to the memories 81a to 4a in the SSSS upper screen 72 corresponding to the divided screens 81 to 84 of the monitor device a8 through contacts a to d. The input 0 output signal generator 73 controls the switch 71 and the D/A converter 74.

Suppose that an emergency situation such as a breakdown or a crime occurs in Elm Beta. When a passenger 9 in the car 1 operates the emergency button 3 in an attempt to contact the outside world, this signal is input to the detection section 41 in the image input device 4, and the operation of the emergency button 3 is detected. This detection is notified to the input signal generation section 42,
In order to generate the input signal s42, image data of a still image sent from the surveillance camera 2 at a predetermined period is converted by the A/Di converter 43, and the data is sent to the storage device 44 and stored in the image storage memory. The stored data is stored in the storage device 4
The data is transmitted to the image reproducing device 7 in the manager's room 6 via the communication line 5 by the communication unit in the manager's room 6 . The data first passes through the contact a of the switch 71, and the memo in the artist playback memory 72 corresponding to the screen 81 of the monitor device [8]. It is input to J81a. The output signal generation section 73 controls the D/A conversion section 74 to convert the data in the image reproduction memory 72 and output it to the monitor device 8 . After inputting the data to the image reproduction memory 81a, the output signal generating section 73 switches the contact a in the switch 71 to the contact O, inputs the data transmitted at a predetermined cycle to the memory 82a, Monitor device 80 split screen 82
will be displayed on the screen. Thereafter, the switching device 71 performs the same operation for the contacts c and d. As a result, the monitor device 8 displays the divided screens 82 sequentially from the screen 81 immediately after the emergency button 3 is operated.
Since still images are displayed at 84 to 84, the behavior of the passengers 9 can be seen.

According to the above embodiment, since the still images l inside the elevator car 1 can be sequentially viewed at a predetermined period after the emergency button 3 is operated, there is no possibility that the emergency button 3 may be operated needlessly and the user simply gets off the elevator. It is possible to easily distinguish whether it is a mischief or a mischief to the equipment in the car, and take appropriate action.
