Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security alarm device.

[0002]

2. Description of the Related Art A security alarm device monitors the status of sensors such as a security sensor, a fire sensor, and a gas leak sensor, and when there is an intruder, a window is broken or opened, or a fire occurs. When a certain abnormality such as a gas leak is detected, a buzzer or bell is rung to notify the occurrence of the abnormality and threaten intruders. It is used in etc. The security sensor includes a heat ray sensor for detecting an intruder, a magnet switch for detecting opening of a window or a door, a vibration detecting sensor for detecting breaking of a window, and the like. Since these security sensors are well known, detailed description thereof will be omitted. Further, since the fire sensor and the gas leak sensor are also well known, detailed description thereof will be omitted.

FIG. 3 is a diagram showing an example of the configuration of a conventional security alarm device. The security alarm device 10 is for notifying a security company through a power supply device 1, a control device 2, a buzzer 3, an indicator light 4 and a telephone line. Equipped with terminals.

The power supply device 1 supplies a predetermined power supply voltage to a sensor, such as a heat ray sensor, which requires a power supply.

The control device 2 takes in the output signal of the sensor, makes the buzzer 3 sound and blinks the emergency light 4 when it is judged that an abnormality has occurred, and calls a predetermined place such as a security company. It reports that an abnormality has occurred through the line.

In FIG. 3, two security sensor loops are connected to the security alarm device 10. One or more security sensors are connected to the security sensor loop.
Assuming that the security alarm device is installed in a general house now, for example, the security sensor loop 1 is connected in series with heat ray sensors and magnet switches installed in various places on the first floor, and the security sensor loop 2 is connected to the security sensor loop 2. Is connected in series with heat ray sensors and magnet switches installed at various locations on the second floor.

In practice, the security alarm device 10 is usually provided with various buttons such as a warning button for setting the control device 2 in a warning state and a release button for canceling the warning state. However, the control device 2 also monitors the states of these buttons, but since it is not an essential matter in the present invention, description thereof will be omitted. Further, although the control device 2 is provided with various functions, these functions are not an essential matter of the present invention, so the description thereof will be omitted. The same applies hereinafter.

When the control device 2 causes the buzzer 3 to ring, the following cases may occur. First, there is a case where the crime prevention sensor operates in the alert state. This is because it is determined that there is an intruder or the window is opened in this case.

Also, when the security state is set and the security sensor loop is abnormal, the control device 2 causes the buzzer 3 to operate.
Sound. For example, the warning button may be pressed while the window is open. In this case, since the magnet sensor installed in the window is operating, the alarm state cannot be set. Therefore, in such a case, the control device 2 causes the buzzer 3 to ring to indicate that the window is open and the alarm state cannot be set.
This is an abnormality of the crime prevention sensor loop. Further, even when the security sensor loop is broken, the control device 2 sounds the buzzer because the security sensor loop is abnormal.

Further, the control device 2 causes the buzzer to sound even when the fire sensor or the gas leak sensor operates.
Note that the control device 2 determines that an abnormality has occurred in the security sensor loop only when the security sensor operates when the security sensor is in the warning state, and when the security sensor loop is in the released state, there is no abnormality even when the security sensor operates. Although it is not judged that it has occurred, sensors related to disaster prevention such as fire sensors and gas leak sensors are constantly monitored, and when these sensors operate, it is always judged as an abnormality and the buzzer 3 sounds and The light 4 is made to blink, and a predetermined place such as a security company is notified that an abnormality has occurred via a telephone line.

At least in the above-mentioned cases, the control device 2 causes the buzzer 3 to ring, but in all of these cases, when the buzzer sound of the same frequency is intermittently interrupted at the same cycle, the surrounding person will It is not possible to recognize whether such an abnormality has occurred.

Therefore, the control device 2 operates when the security sensor operates while in the alert state, when there is an abnormality in the security sensor loop, when a fire occurs, or when a gas leak occurs. , Buzzer 3 is set to ring in a different manner. That is, in each case, the frequency of the buzzer sound and the intermittent period are different.

[0013]

However, the case where it is desired to call attention to those around the person is not limited to the above case. There is a case where an abnormality occurs in the power supply device 1 and the predetermined power supply voltage is not output. For example, the circuit board and wiring of the power supply device 1 may be bitten by a mouse, or rainwater may enter the inside of the power supply device to cause a short circuit. In such a case, an excessive current flows, so that the fuse of the power supply device 1 is blown. An abnormality occurs that the predetermined power supply voltage is not output.

When the power supply device 1 becomes abnormal due to a blown fuse or the like, these sensors do not operate because the power supply voltage is not supplied to the heat ray sensor and other sensors that require a power supply, and therefore the power supply device 1 fails. When the warning button is pressed in this state, the control device 2 determines that the crime prevention sensor loop is abnormal and causes the buzzer 3 to ring in a predetermined manner. As a result, the sensor is inspected, but in many cases, it cannot be considered that an abnormality has occurred in the power supply device 1.

Therefore, it is necessary to let the surrounding people notice the abnormality of the power supply device 1. In this case, the buzzer 3 is used.
It is not a good idea to ring. This is because when the buzzer 3 sounds, there are some cases as described above, and if the buzzer 3 sounds even when an abnormality occurs in the power supply device 1, even if the buzzer 3 sounds as described above, , The buzzer 3 will often ring even if the buzzer 3 is ringing in a different manner, and it will be difficult for surrounding people to clearly distinguish what is causing the buzzer 3 to ring. Is.

An object of the present invention is to solve the above-mentioned problems and to provide a crime prevention alarm device capable of clearly notifying surrounding persons that an abnormality has occurred in a power supply device. It is a thing.
