Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a security device, and more particularly to a notification device that preferentially displays security information on the screen of a home television receiver.

[Prior Art] When security devices in homes, offices, etc. detect an abnormality such as a fire, gas leak, or intrusion by a suspicious person, they display the abnormality on a display and emit a bell sound or synthesized voice. There are some systems that issue V-reports using the following methods. However, with such conventional security devices, when a bell or audio alarm is issued, for example, the sound is drowned out by loud noises coming from a television receiver or audio equipment. There were times when the alarm could not be heard indoors, making it impossible to take immediate action such as evacuating. This problem can almost be solved by installing f-alarm devices etc. in each room, but this requires a huge amount of money, and while it may be possible when constructing a new building, it may be difficult to carry out construction after construction. was there. For this reason, there has been a desire for a device that can quickly notify the user through images and sounds when an abnormality occurs without the need for such construction work.

[Problems to be Solved by the Invention] Conventional security devices notify residents when an abnormality occurs by issuing an alarm using a bell sound or synthesized voice. This system attempts to solve the problem that the security information signal is sometimes drowned out by the sound source and not transmitted to the residents.The security information signal is converted to a TV signal and mixed with the TV antenna signal, while the signal is transmitted to the home TV receiver. If the receiver is turned off, it detects this, automatically turns on the power, and sends out a remote control signal to switch the reception channel, allowing the security information signal mixed with the antenna signal to be transmitted to the TV receiver as an image. The present invention provides a security information notifying device that outputs and notifies by voice.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a detection section that detects fire, gas leak, intrusion of a suspicious person, etc., and a security device that issues an alarm based on the detection signal.

Provided is a security information notification device comprising a remote control signal that remotely operates a television receiver based on a signal from a television receiver operation detector and a remote control signal generator that generates a remote control signal that switches the receiving channel to a set channel. It is something to do.

[Operation] Since the present invention is configured as described above, when a fire, gas leak, intrusion of a suspicious person, etc. is detected, image and audio signals to warn of these are modulated into a TV signal of an empty TV broadcast channel. At the same time, if the power of the television receiver is off, it is turned on, the reception channel is switched to the above channel, and the television receiver notifies the occurrence of an abnormal situation with images and sounds.

[Example] Hereinafter, a security information notification device according to the present invention will be described in detail based on the drawings.

Fig. 1 is a schematic diagram of the main parts of an embodiment of the security information notification device according to the present invention, and Fig. 2 shows an arrangement of sensors for detecting fire, gas leakage, and intrusion of suspicious persons in the security information notification device. Embodiment FIG. 3 is an example of a data table used in the security information notification device. In FIG. 1, reference numeral 1 denotes a detection unit that detects fire, gas leakage, intrusion of suspicious persons, etc., and outputs a code signal indicating the cause and location of the abnormality. Reference numeral 2 denotes a central processing unit (hereinafter abbreviated as CPU) which performs arithmetic processing on the detection signal from the detection unit 1. 3 is a memory unit that temporarily records data calculated by the CPU 2 in a RAM (random access memory) or the like. Reference numeral 4 denotes a storage unit that stores code data such as fire, gas leak, intrusion of a suspicious person, etc., and code data of location. Reference numeral 5 denotes an identification section that compares the data recorded in the memory section 3 with the data stored in the storage section 4, discriminates and outputs signals of matching data.

Reference numeral 6 denotes an image data storage unit that stores image data such as display of fire, gas leak, intrusion of a suspicious person, etc., and display of location. Reference numeral 7 denotes an image signal generation section, which reads out the corresponding image data signal from the image data storage section 6 based on the signal discriminated by the identification section 5, and generates a television image signal. Reference numeral 8 denotes a voice data storage unit which stores voice data for telling where a fire, gas leak, intrusion by a suspicious person, etc. has occurred.

Reference numeral 9 denotes an audio signal synthesis section, which reads the corresponding audio data signal from the audio data storage section 8 based on the signal discriminated by the identification section 5, and synthesizes the audio signal. Reference numeral 10 denotes a television signal output section which mixes the image signal from the image signal generation section 7 and the audio signal from the audio signal synthesis section 9, modulates the mixture into a television signal of an empty channel of television broadcasting, and outputs the mixture. Reference numeral 11 denotes a television receiver operation detection section, for example, a pickup coil is provided on an adapter inserted into a power outlet, the current is detected by the pink-up coil, and the current flowing into the television receiver is determined to be a set value, that is, A signal is output when a current of 300 milliamps or more is flowing, which indicates that the television receiver is in operation. Reference numeral 12 denotes a remote control signal generating section, and based on the signal from the identification section 5, if no signal is output from the television receiver operation detecting section 11, first,
Generates a power-on remote control signal to turn on the television receiver.

Thereafter, after a period of time necessary for the television receiver to reach the receiving state, for example, 5 seconds, a remote control signal is generated for switching the reception channel of the television receiver to the channel of the signal output by the television signal output section 10. . Note that when a signal is being output from the television receiver operation detection section 11, a remote control signal for turning on the power is not generated. This is because normally, the remote control signal for turning on and off the TV receiver is the same for on and off, and the TV receiver repeats power on and power off every time the remote control signal is input. This is because

In addition, in the second review, the six-digit numbers such as 110001 are the codes of the signals output by each sensor, and as shown in the third data table, they represent the location where each sensor is installed and the cause of the abnormality. There is. That is, for example, 100
001 and 100011 are the codes of the signals output by the gas leak sensor installed in the kitchen, and 110101 is the code of the signals output by the fire sensor installed in the bathroom.
011111 is the code of the signal output by the suspicious person intrusion sensor installed at the entrance.

In this embodiment, of the six-digit code number, the top three digits specify the location, and the bottom three digits are used to identify each sensor. The code signals output by these sensors are processed in the first CPLI 2 and stored in the memory section 3.

Next, the operation of the security information notification device according to the present invention will be explained. First, when an abnormality occurs, the sensor of the detection unit 1 detects the abnormality and outputs a signal. For example, in a kitchen, two gas leak sensors (1000 inch and 100011 code sensors) detect gas leaks and output respective code signals. In this example, two sensors are provided because, for example, one sensor happens to detect a gas leak and
01 code detection signal was output, but if this gas leak is a very small amount that occurs during ignition and is not a problem, and the other sensor does not detect any abnormality, the gas is detected. This is to prevent a false alarm from being reported as an occurrence of an abnormality even though there is no need to notify the leak. When a suspicious person intrusion sensor or only one sensor of the same type is placed in one place, if this sensor detects an abnormality, it is designed to immediately notify the occurrence of an abnormality. Now, these detection signals are processed by CPtJ2, and the obtained data is temporarily recorded in the RAM of the memory section 3, etc.

This recorded data is read out by the identification unit 5 via the CPU 2, and compared with each data such as the cause and location of the abnormality read out from the storage unit 4 via the CPU 2, and a signal of the data that matches is obtained. , for example, determines and outputs a signal indicating a ``gas leak'' in the ``kitchen''. At this time, if the signal input from the sensor of the detection unit 1 is due to a malfunction, etc., it is determined to be a false alarm because there is no matching data in the data stored in the storage unit 4, and the signal is recorded in the memory unit 3. The data will be automatically deleted. Note that the data recorded in this memory section 3 is erased by resetting. Now, the signal from the identification section 5 is input to the image data storage section 6 and the audio data storage section 8 via the CPU 2, and the image data storage section 6 stores, for example, the words "kitchen" and the picture "gas leak". The audio data storage section 8 outputs audio data such as "Gas is leaking in the kitchen." The image signal generation section 7 generates and outputs a television image signal based on the image data from the image data storage section 6, and the audio signal synthesis section 9 synthesizes an audio signal based on the audio data from the audio data storage section 8. and output it. These television image signals and audio signals are modulated by the television signal output unit 10 into a television signal of an empty channel of television broadcasting. The television signal modulated by the television signal output section 10 is applied to a television signal mixer (not shown), mixed into a television broadcast signal, and transmitted to a television receiver via a coaxial cable line or the like.

On the other hand, when the television receiver is in operation, a signal from the television receiver operation detection section 11 via an adapter or the like connected to the power outlet of the television receiver is transmitted to the identification section 5 via the CPU 2.
, the television receiver is determined to be in operation, and when the identification unit 5 confirms abnormality occurrence data, the CP
The channel signal of the vacant channel is immediately output from the remote control signal generator 12 via U2, and the channel of the television receiver is switched. If the television receiver is not operating, no detection signal is output from the television receiver operation detection section 11, so if the identification section 5 confirms abnormality occurrence data, the remote control A signal generator 12 generates a remote control signal for turning on the television receiver.

With this power-on signal, the television receiver, for example,
After a second, the normal reception state is reached, and at approximately this timing, the remote control signal generator 12 outputs the channel signal of the vacant channel, and the reception channel of the television receiver is switched.

As a result of the above, when an abnormality occurs in the television receiver,
Security information is automatically output as images and sounds to notify residents. The remote control signal generator is connected to this device by wire or wirelessly (radio waves, light, etc.) and outputs a remote control signal by infrared rays, etc. to the TV receiver at each location where the TV receiver is installed. . In addition, to detect whether or not the TV receiver is operating, the brightness of the screen of the TV receiver is constantly detected, and if the average value of the brightness over the required time, for example, one minute, is detected to be at a level higher than normal external light. You can also confirm that it is working. In the above, it is assumed that the image signal and audio signal are modulated into the TV signal of the vacant channel, but the video signal and audio signal are transmitted to the TV receiver via a coaxial cable line etc. without being modulated, and the video input terminal and audio input terminal Alternatively, the video input mode may be switched to the video input mode using a remote control signal output from the remote control signal generating section 12.

In addition, in the above, each sensor outputs both the code for the location and the cause of the abnormality, but each sensor outputs only the code for the cause of the abnormality, so that the location of each sensor can be identified on the equipment side. It may be configured as follows.

[Effects of the Invention] As explained above, in the security information notification device according to the present invention, when a fire, gas leak, intrusion of a suspicious person, etc. is detected, information on this abnormality is automatically transmitted by the television receiver. Images and sounds are output, so even if you are unable to hear the bell or sound of a conventional notification device, if you have a TV set in your room, you can receive images or sounds using this TV set. Alternatively, the occurrence of an abnormality can be known by both images and sounds, and actions such as evacuation can be taken quickly.
