Description

[Detailed Description of the Invention] Is this invention inside the elevator car? This relates to the improvement of a security device that takes pictures using a television (J2 is referred to as lower television) camera.

In recent years, crimes occurring inside elevator cars have been increasing and are becoming a social problem. Therefore, a TV camera is installed inside the car and remotely monitored using a TV receiver. For example, (3LzvAToRwoRL)

ToRccTvSECURITY'' is also shown. However, since TV cameras and receivers have a short lifespan,
Administrators and others turn on the switch and operate it as needed. In addition to the TV camera and TV receiver, it is also possible to use a Video Cheap Recorder, but this also requires the administrator to operate it, which requires a lot of effort. Further, the fact that the above-mentioned surveillance is being carried out is not known to the criminal who is waiting for an opportunity at the boarding point, and it is not possible to give advance warning to the criminal.

This invention aims to improve the above-mentioned problems by providing a security display in the landing area in addition to the television camera and television receiver, and by making the operating conditions of the security display different from those of the television camera and television receiver. To provide a crime prevention device for an elevator that can give advance warning to a criminal and prevent shortening of the lifespan of a television camera, television receiver, etc.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3.

In the figure, fi+ is a TV camera that is installed inside the elevator car and is configured to use a wide-angle lens to photograph the metal body inside the car. A distributor that sends this out via a coaxial cable, a television receiver installed in the +31 Fi boarding area or the manager's room and connected to the distributor (2),

When a down-hall call is registered with a button, the down-call registration signal becomes "H", (8) is a counter that counts and outputs the number of inputs that become "1-H", (9) corresponds to ld I K (10) is a coincidence detector whose output becomes rHJ when input A and input B match, (+1) is a stop command signal which becomes "H" when the car decides to stop, (I21 is AN

For example, 30 seconds) A monostable element whose output reaches "H", (I4

1゜091 is the OR gate, Wa third relay, (20a

VC, a delay element whose output is rLJK for a certain period of time (for example, 1 minute), (B) is the first relay, (27a) is its normally open contact, (2) is installed in the landing on the first floor, and when it lights up, for example Security indicator displaying “Security TV monitoring”, R
, S is an AC power supply.

Next, how does this example work? explain.

Their registration signals (51) to (56), (61) to (6
5), any one of (72) to (76) l”J vc
If so, one of the outputs of OR gates (4) to (c) will be rl, and the output of OR gate (4) will also be raJ. Eventually, the output of the delay element (5) also becomes "R", the first relay is energized, and the contact (27a) is closed. This will turn on the security indicator, giving a warning to anyone looking for an opportunity to commit a crime. On the other hand, the number of registered car calls is counted by a counter (8), and if the number is 2 or more, that is, if there are 2 or more passengers in the car,
The output of the coincidence detector (1o) is rLJ.

Suppose that there is only one passenger in the car, and the car is traveling up an upper floor, for example, the 6th floor, with all calls registered.

At this point, only the car call registration signal (56) becomes rHJ and the counter (8) outputs 1, so the coincidence detector (
The output of lO) becomes 1drHJ. While the car was running, a call was registered on the 6th floor and it was called 1. When the car approaches the 6th floor and decides to stop, the stop command signal 111) becomes rHJ,
AND game 1- (+21 output becomes rHJ.

With this, the output of the monostable element (13) is 30 seconds j...raJ
Therefore, the output of OR gate t+81 and Q special is "H"
Therefore, the second and third relays (4) and υ are energized,
Contacts (2: la) + ' (raa) + 7j are each closed, and the television camera (1), television receiver (3), and video recording device (4) are each operated for 30 seconds. In other words, the situation in the corner is photographed by a television camera (Ilff) and monitored by a television receiver (3) in the hall or manager's room.The video is recorded by a video recording device (4). .Therefore, if an abnormality occurs in the car,
It is possible to deal with this immediately and to grasp the evidence at a later date.

On the other hand, when the car arrives at the 6th floor, the car call and hall call are canceled, so the output T of OR gates (4) to (c)
l1rLJ, and the output of the OR gate (c) also becomes rLj. Now, the output of delay element (2) will be rL after 1 minute.
Therefore, the first relay @ is deenergized, the contact (27a) is opened, and the security indicator C1j3 is turned off. Thereafter, when either a car call or a hall call is registered, the first relay @ is energized again and the security display @ lights up.

In addition, when a car is running toward the 6th floor with a car call and a landing call is registered at an intermediate floor and the car stops at that floor, the TV camera (1) and TV receiver (3) will be activated for 30 seconds as described above.
) and the video recording device (4) are activated.

When a car with only one passenger stops in this way,
Since there are many opportunities for crime to occur, it is a good idea to start monitoring the inside of the car, and even when these devices are not working, the crime prevention indicator lights up to issue a warning. Moreover, since the operating time of the television camera (l), television receiver (3), and video recording device (4) is shortened, shortening of their life spans is prevented. Also, video recording device (4)
The time and effort required to view the playback screen is reduced.

Furthermore, even when the TV monitoring request switch is closed,
OR game) (+81, (+9) output is rl(J
Therefore, the same monitoring as described above is performed. Also, earthquakes,
When a fire or malfunction occurs, the output of only the OR gate (19) becomes "H" and monitoring is performed by the television camera t1+ and the television receiver (3). In this case as well, the operating conditions are varied as described above to prevent shortening of the life of the equipment.

Alternatively, it is also possible to implement as follows.

(7) Even in the event of an earthquake, fire, or breakdown, the third relay wire is energized and the video recording device (4) is fully activated.

g) A detector is installed to detect knives and other weapons using light, ultrasonic waves, etc., and only when the detector is activated, a television camera (1)
, operate the television receiver (3) and video recording equipment (4)k. Also, at this time, only one screen is recorded as a still image.

(1) The operating conditions of the television camera (1), television receiver (3), and video recording device (4) are not limited to those in the embodiment, and are set assuming a case where a crime is likely to occur. Also, ensure that all elevators are in operation while in service.

2) Security indicators will be installed on all floors, not just the first floor.

(9) A television camera illumination constructed with a long-life solid-state imaging device is used.

(b) The TV camera is configured so that a standard lens is used instead of a fullc wide-angle lens, a convex mirror is installed inside the cage, and its image is photographed by the TV camera fi+.

2) Set up a mirror that reflects the blind spot of the TV camera (fl), and take a picture of this mirror.

As explained above, in this invention, a television camera and a television receiver are installed in the car, a security display is installed in the landing, and the operating conditions of the security display are made different from the operating conditions of the television camera and television receiver. Therefore, advance warning can be given to the criminal, and shortening of the lifespan of the television camera and television receiver can be prevented. .

tx and video recording devices are used, and their operating conditions are made to differ, so it is possible to ascertain later evidence of the crime, and it is possible to reduce the time and effort required to view the playback screen of the video recording device.
