Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an abnormality monitoring device in high-rise housing such as condominiums and public housing, and is particularly effective for crime prevention and abnormality monitoring in elevator cars.

[Conventional technology]

In recent years, high-rise housing has tended to become larger and taller, but on the other hand, the sense of solidarity among the residents of each unit has declined, and the question of how to take crime prevention and disaster prevention measures within buildings has become a major social issue. It is becoming.

For example, when it comes to crime, there is a tendency for crimes to occur frequently, especially in elevator cars. Conventional crime prevention measures include installing emergency buttons and intercoms inside the car, and filming the inside of the car with a TV camera, which is then sent to the manager. By monitoring on the room monitor TV or detecting abnormal vibrations and noise inside the car, or by detecting abnormal human movements using ultrasonic waves or spatial filters, Measures are being taken, such as notifying customers of the situation and switching to forced stop operation on each floor.

[Problem to be solved by the invention]

Among the conventional methods, the method of monitoring on the monitor TV in the manager's room relies heavily on the building manager, and if the manager is absent or neglects his monitoring duties, it becomes difficult to prevent crime. cannot be expected at all. Additionally, methods that rely on coincidence such as notifying the hall of a crime or abnormality in the car or stopping operation on each floor are insufficient, as there are often no people present at night. It is not possible to expect a significant crime prevention effect.

Furthermore, even if an external service company, security company, etc. is automatically notified, their arrival at the scene is often delayed and they are often unable to respond in time to an emergency situation.

[Means to solve the problem]

The present invention focuses on the fact that high-rise residential buildings are equipped with common television reception equipment to prevent difficult viewing and the proliferation of antennas in each apartment, and uses this to detect any abnormality in the elevator car. In some cases, the present invention is characterized by being equipped with a means for projecting the situation inside the car on a part of the screen of each home television.

〔Example〕

The figure is a block diagram showing one embodiment of the overall configuration of the present invention. In the figure, 1 is a VHF antenna,
2 is a UHF antenna, 3 and 4 are receiving amplifiers, 5
6 is a mixer for combining signals input from multiple input terminals into one output terminal, and 6 is a mixer for each channel of input signals (here, the number of channels is n)
7a to 7n are amplifiers for each channel; 8a to 8n are demodulators to restore the TV radio signal to video and audio signals; 10 is a microphone installed in the manager's room; 11 is a A television camera installed in the elevator car, 13 an abnormality detection device installed in the elevator car, 12 a control device that controls a monitor signal according to the output of the abnormality detection device 13, and 14 installed inside the building. Fire alarm (however, only one is shown, the same applies to various abnormality detectors below), 15 is its receiver, 16 is an earthquake detector, 17 is its receiver, 18 is an intruder monitoring sensor, 19 is The receiver, 20 is a gas leak detector, 21 is the receiver, 24 is a monitor TV installed in the manager's room, and 25 is a VTR/tape coder device that outputs pre-recorded or recorded signals according to input signals. , 30 is a video and audio processing device.

This video and audio processing device 30 has the following functions: (1) Adjustment of video and audio Once the received radio waves are converted into an IF band, they are separated into a video signal and an audio signal. Then, the output from 25 is mixed with the video signal of each channel, and AGC and limiter are applied.

If there is no output from 25, the video signal will not be mixed, and only the AGC and limiter will be applied.

(2) Synchronization signal generation When mixing screens (mixing video signals) or switching screens, a synchronization signal is supplied to prevent image distortion.

(3) Automatic transmission Combines video and audio signals, converts and transmits to each channel.

The circuit performs the following three functions, but since this is a well-known technology, the details of the circuit will be omitted.

31a to 31n are modulators for converting the video signal and audio signal of each channel into television radio waves; 32 is a modulator for converting into a specific television radio wave frequency in order to provide various information by utilizing empty channels; 34; is a mixer having the same function as 5, 35 is a distributor that equally distributes the input signal, 35A to 35N
is a main line serving as a transmission path to each house, and this main line is connected to the home television of each house via a branch (not shown). 33 is an audio demodulator, and 36 is a speaker used for broadcast guidance.

With the above configuration, if the abnormality detection device 13 in the elevator car is activated for some reason, an image of the inside of the car is displayed on the monitor TV 24 in the manager's room via the control device 12, and
Via the VTR/tape recorder device 25 and the video/audio processing device 30, the contents or the situation inside the car are projected as images on a part of the screen (hereinafter referred to as a sub-screen) of each home television.

For example, as an abnormality detection device in a car,
- By using No. 109373 “Elevator Car Abnormality Detection Device”, it is possible to obtain stage-based outputs depending on the abnormality situation, and in the first stage, the TV sub-screen will display “The security sensor of car No. 0 has been activated”. ", and in the second and third stages, the situation inside the car is displayed on the sub-screen, and a message saying "stop at floor XX" is displayed and a warning sound is emitted from the TV (however, the monitor TV 24 does not display the warning sound). It is possible to do things like display the situation inside the car at the first stage. Of course, in this case, since the video is displayed on the sub-screen, the program that the resident is watching can be continued without interruption, so there is no problem.

〔Effect of the invention〕

According to the present invention, even when the manager is absent or no one is present in the elevator hall,
If there are residents watching TV, they will be able to notice crimes or abnormal situations occurring inside the elevator car, and this will be highly effective in early detection and prevention of abnormalities or crimes inside the elevator car. In addition, the present invention can be implemented without making any changes to ordinary home televisions, and information is provided to each household, which increases the sense of collective defense for crime prevention and disaster prevention, improves the sense of solidarity among residents, and improves high-rise housing. This is a very effective means of preventing crime in elevators.
