DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an erroneous operation prevention device in a security system.

[0002]

2. Description of the Related Art In a comprehensive security system for a building, a security start signal is transmitted to a security center after all doors have been closed, and the building is set to a security state.
Then, when a locked door or the like is opened while it is set in a security state, a sensor provided on the door detects that fact and sends an alarm to a security center as a suspicious person intrudes. In response to this warning, security personnel such as a security company rush to the site.

[0003]

However, there are many false alarms due to the inadvertent opening of a door or the like without releasing the security state during the transmission of this alarm. For example, when an employee who is set in the security state returns to retrieve a forgotten item, the employee inadvertently opens a door or the like without releasing the security state. In other words, the operation error has been a major cause of false reports.

[0004] Therefore, the following problems have occurred. Even in the case of false alarms caused by the above-mentioned erroneous operations, security guards must rush to the site to check for abnormalities, so security staff must be secured to respond to them, resulting in a security company However, there is a problem that the cost of the method is significantly increased. If a security guard is dispatched due to an erroneous operation due to an erroneous operation of the security requester, a cost is incurred accordingly. However, there is also a problem that it is not easy to specify whether or not the cost burden is an erroneous report due to an erroneous operation of the security client.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a simple alerting device so that a door is not inadvertently opened without releasing a security state.

The electric motor 3 as a driving unit is fixed to the wall 4. A warning stick 6 is fixed to the output shaft of the electric motor 3. The alerting rod 6 is configured to rotate in the direction of the arrow shown in the figure according to the rotation of the electric motor 3. In this embodiment, the electric motor 3 and the alert rod 6 are directly connected. However, it is obvious that they may be linked via a speed reducer. As shown in FIGS. 2 and 3, the alerting rod 6 is formed with a shear stress concentration portion 7 composed of a groove or the like, and is easily broken at that portion. Then, as shown in FIG. 2, a latch member 8 is fixed to the door 5. The latch member 8 is formed with a hole 8a for inserting the alert bar 6. The latch member 8 is effective when installing the device on the existing door 5.

[0008] When an electric motor 3 as a driving means can be incorporated in the wall 4 in advance, as in a new building or the like, a warning stick 6 is provided on a part of the door 5 as shown in FIG. It is also possible to form a hole 9 through which the ingress and egress can be made, and to directly insert the warning stick 6 into the hole 9. Further, depending on the structure of the building, a drive unit including the electric motor 3 may be provided on the door 5 side, and the latch member 8 may be provided on the wall 4.
Reference numeral 1 denotes a transmission means for transmitting the setting to the security state to the security center 2 of the security company.
The electric motor 3 is driven in accordance with a signal from the transmitting means 1. Therefore, when a signal indicating that the security state has been set is output from the transmission means 1, the electric motor 3 is driven and the signal rod 6 is moved to the hole 8a.
Keep the alert position inserted inside. Conversely, when the security state is released, the release position where the alert bar 6 comes off the hole 8a is maintained.

Next, the operation of this embodiment will be described. When setting the security state, first, the door 5 is locked on the wall 4. Next, the security system (not shown) is switched to the security state. Then, the electric motor 3 operates,
The alert bar 6 provided on this shaft is rotated via the output shaft, and its tip is inserted into the hole 8a of the latch member 8 to keep the alert position. When the alert bar 6 is in the alert position as described above, even if the door 5 is opened, the door 5 cannot be opened unless the alert bar 6 is broken from the shear stress concentration portion 7. If you forcibly open it, a warning stick 6
Is broken from the shear stress concentration portion 7, so that the door 5
Will be opened.

After all, the user can be alerted to the fact that the security state is being set as long as the alert bar 6 does not break. Then, the person who knows that there is the alert bar 6 stops opening the door 5 at that time. Then, the security state is released, the alert bar 6 is moved to the release position, and then the door 5 is opened again.
If a legitimate visitor forcibly opens the door 5, the alert bar 6 breaks from the shear stress concentration portion 7,
At this time, it is clear that the operation is incorrect. In addition, an unauthorized intruder who does not know the presence of the warning stick 6 forcibly opens the door 5, and at that time, the transmitting means 1 operates to notify the security center 2 that the unauthorized intrusion has occurred. become.

[0011] In the prior art, it has not been easy to judge whether the alarm signal is a false report due to a failure of the security device or a false report due to an operation error of the client. However, according to the device of this embodiment, whether an operation error or a false
It can be determined whether or not the alert bar 6 is damaged, and the responsibilities are clarified. Therefore, troubles between the security company and the client can be prevented. In addition, since the alerting rod 6 is broken from the shear stress concentration portion 7, it does not damage the electric motor 3 and can be used any number of times just by replacing the alerting rod 6. In addition, since the configuration is simple, the cost can be reduced. In this embodiment, the alert bar 6 is rotated by the electric motor 3, but the alert bar 6 may be linearly moved using a solenoid.

Next, commonly used in this embodiment,
The shape of the alert bar 6 will be described with reference to FIGS. In the alerting bar 6 shown in FIG. 3, the shear stress concentration portion 7 is constituted by a groove provided on the entire circumference, and is easily broken from this groove. Warning stick 6 shown in FIG.
Is a shape in which the shear stress concentration portion 7 has a wedge shape on one side, and the degree of stress concentration is higher than the shape shown in FIG.
It easily breaks when a force is applied. The alert bar 6 shown in FIG. 5 is provided with a wedge-shaped shear stress concentration portion 7 over the entire circumference, and is designed to be more easily broken than the shape shown in FIG.

Since the breaking force acting on the signal bar 6 varies depending on the weight of the door 5, the signal bar 6 having a shear stress concentration portion 7 suitable for the door 5 is selected. Furthermore, each tip portion 6a of these alert bars 6 is rounded so that it can be easily inserted into the hole 8a.
