Conventionally, in a security device used in a facility having a plurality of areas such as a tenant building, an operation mode for each area is stored, and a detection signal is output from a sensor installed in an area where the operation mode is the security mode. When input, an alarm is transmitted to a remote monitoring center or the like via a communication line to notify the occurrence of an abnormality. In such a security device, the operation mode of the tenant can be switched to a security release mode or a security mode by a manual operation of an administrator of each tenant. In addition, regarding the operation mode of the common unit, the first person or the last exit person switches the operation mode of the common unit by the operation device installed in the common unit.

However, since the last leaver forgets the operation of switching the operation mode of the common unit by the operating device, or the person who leaves the terminal does not know whether he or she is the last leaver, no one performs the operation of switching the operation mode of the common unit. In other words, there was a situation in which the common area was left without security, even though the tenant building was unmanned.

[0005] Due to such security problems,
As disclosed in Japanese Patent Application Laid-Open No. 55-74697, there has been proposed a security device that automatically switches the common use section to the security mode after a predetermined time has elapsed from detecting that all the tenants have entered the security mode.

[0006]

However, in the conventional security device, for example, if the window of the common area is left open when the last exiting person leaves, the common area is automatically opened after the last exiting person leaves. If you switch to security mode,
There is a problem that a sensor installed in the common area detects that the window of the common area is open and automatically sends an alarm to a security center or a police station.

Therefore, the present invention solves the above problems, reduces unnecessary transmission of alarms, and can reliably switch the common use section to the security mode when the facility becomes unmanned. The purpose is to provide.

For convenience of explanation, only one central control device 16 connected to the security center 10 and only one tenant control device 18 connected to the central control device 16 are shown. However, the central control device 16 connected to the security center 10 may be plural, and the central control device that has transmitted the signal based on the device number transmitted from the central control device 16 in the security center 10. 16 may be identified. Similarly, the centralized control device 16 may identify the tenant control device 18 that has output the signal based on the identification number output from the tenant control device 18.

The security processing procedure of the central control unit 16, the common unit control unit 17, and the tenant control unit 18 shown in FIG. 1 will be described below in detail.

FIGS. 2, 3 and 4 are flowcharts showing the operation of the tenant control unit 18, the centralized control unit 16 and the common unit control unit 17, respectively. First, an operation when a tenant user leaves will be described.

The user of the tenant performs a security start operation using the operation unit 180 of the tenant control device 18 of the tenant used by the tenant. The operation unit 180 outputs a security start signal to the control unit 181 when a security start operation is performed by the user.

When a security start signal is input from the operation unit 180 (step S10), the control unit 181 switches the operation mode from the security release mode to the security mode, and controls each tenant control in advance to identify the tenant control device 18. An identification number set for each device 18 and a security start signal indicating that a security start operation has been performed are output to the centralized control device 16.

When the identification number and the security start signal are input from the tenant control unit 18 (step S20), the control unit 160 of the central control unit 16 stores the input signal in the storage unit 16
Output to 2. The storage unit 162 changes the operation mode stored corresponding to the identification number to the security mode based on the input signal from the control unit 160.

Then, the control section 160 checks whether or not all the operation modes corresponding to the identification numbers except the identification number indicating the shared section control device 17 stored in the storage section 162 are in the security mode (step S21). ). At this time, if there is an identification number that is not in the security mode, it is determined that there is a tenant with a user, and the process returns to step S20.

If the operation mode corresponding to all the identification numbers except the identification number indicating the common unit control device 17 is the security mode in step S21, the control unit 160 starts security for the common unit control device 17. A command signal is output (step S22).

When the security start command signal from the central control unit 16 is input (step S30), the control unit 170 of the common unit control unit 17 outputs a start signal to the timer 171a (step S31) and installs it in the common unit. It is checked whether or not the detected signal from the sensor 41 is input (step S32). At this time, if the detection signal from the sensor 41 is not input, the message storage unit 17
From among the messages stored in Step 2, a message urging the user to leave (for example, “Start security in the entire building.”; Hereinafter, referred to as normal guidance) is read out, and the notification unit 38 is provided.
(Step S35).

If the detection signal from the sensor 41 has been input in step S32, the control unit 170
Among the messages stored in the message storage unit 172, a message prompting the user to check the security status (for example, forgetting to lock or lock) of the common unit (for example, “The first floor window is open. Check it.”). Hereinafter, this is referred to as abnormal guidance) and output to the notification unit (step S3).
3). In addition, as a result of outputting the abnormal guidance in step S33, the security status of the common part is set to the normal state by the exit person (all windows of the common part are closed, and the windows and doors are locked), and the sensor 41 When the detection signal from is no longer obtained (step S34), the control unit 170
The process shifts to step S35 to output normal guidance to the notification unit 38.

The notification unit 38 outputs normal guidance or abnormal guidance input from the control unit 170 by voice, text, or the like.
Alternatively, the notification is made by an image or the like. The control unit 170 determines whether or not the detection signal from the sensor 41 is being input while outputting the normal guidance to the notification unit 38 (step S3).
6) It is determined whether or not the time counted by the timer 171a is 1 minute remaining (step S37) and whether or not the exit signal from the exit button 39 is input (step S38).

If the detection signal from the sensor 41 has been input in step S36, the control unit 170 proceeds to step S43 to be described later, and determines whether or not the time-out signal from the timer 171a or 171b has been input. If it is confirmed that the timing end signal has not been input, the process proceeds to step S33, and abnormal guidance is output to the notification unit 38.

In step S37, the timer 1
If the time counted for 71 a is 1 minute remaining, the message stored in the message storage
A message to inform the departure that the security of the common area will be started soon (for example, "You are the last departure. Security of the whole building will be started soon. Please leave immediately." The exit guidance is referred to) and output to the notification unit 38 (step S39).

Note that the time counted by the timer 171a is 1
When the exit button 39 is operated by the exit person when there are more than minutes, an exit signal is output from the exit button 39 and input to the control unit 170. The controller 170 controls the exit button 3
When the exit signal from the timer 9 is input, the timer 171a stops counting time, resets the timer, and outputs an activation signal to the timer 171b. The exit guidance is read out of the messages stored in the message storage unit 172 and output to the notification unit 38 (step S39). The notification unit 38 notifies the exit guidance input from the control unit 170 by voice, characters, images, or the like.

While outputting the exit guidance to the notifying unit 38, the control unit 170 determines whether or not a detection signal from the sensor 41 is being input (step S40) and determines whether the timer 17
It is determined whether or not a timing end signal has been input from the timer 1a or the timer 171b (step S41).

When the detection signal from the sensor 41 is input in step S40, the control unit 170 proceeds to step S43 to be described later, and determines whether or not the timing end signal from the timer 171a or 171b is input. If it is confirmed that the timing end signal has not been input, the process proceeds to step S33, and abnormal guidance is output to the notification unit 38.

In step S41, the timer 1
When the timekeeping end signal from the timer 71a or the timer 171b is input, the operation mode is switched to the security mode, and the common unit controller 1
7 and an identification number for identifying the common unit controller 17 and a security start signal.

When the identification number and the security start signal from the common unit control unit 17 are input, the control unit 160 of the central control unit 16 outputs the input signal to the storage unit 162. The storage unit 162 changes the operation mode stored corresponding to the identification number, that is, the operation mode of the common unit control device 17 to the security mode based on the input signal from the control unit 160.

In step S33, the control unit 170 of the common unit control unit 17 determines whether or not the detection signal from the sensor 41 is being input while the abnormal guidance is being output to the notification unit 38 (step S34) and a timer. It is determined whether or not a time measurement end signal has been input from the timer 171a or the timer 171b (step S43).

If the detection signal from the sensor 41 has not been input in step S34, the control unit 170 proceeds to step S35 and outputs normal guidance to the notification unit 38.

If the control unit 170 determines in step S43 that the timer end signal from the timer 171a or 171b has not been input, the control unit 170 proceeds to step S43.
The process proceeds to 46, where it is determined whether an extension signal from the extension button 47 has been input. If no extension signal is input,
The process proceeds to step 33 and outputs normal guidance to the notification unit 38.

On the other hand, if the control unit 170 determines in step S43 that an extension signal has been input from the extension button 47, the control unit 170 determines whether the timer 171a or the timer 1 is in operation.
The timer 71b is terminated and reset, and a start signal is output to the timer 171a.
Return to the processing of.

In step S43, the timer 1
When the timekeeping end signal from the timer 71a or the timer 171b is input, the operation mode is switched to the security mode, and an identification number and a security start signal for identifying the common unit control device 17 to the central control device 16 are provided. And outputs an alarm including information indicating the type of abnormality in response to a detection signal from the sensor 41.

When the identification number, the security start signal and the alarm from the common unit control unit 17 are input, the control unit 160 of the central control unit 16 outputs the identification number and the security start signal of the input signals to the storage unit 162. I do. The storage unit 162 changes the operation mode stored corresponding to the identification number, that is, the operation mode of the common unit control device 17 to the security mode based on the input signal from the control unit 160. Further, the communication control unit 161 outputs a device number assigned to each central control device 16 in advance to identify the central control device 16, an identification number from the common unit control device 17, and an alarm.

When the device number, the identification number and the alarm are input from the control unit 160, the communication control unit 161 transmits the input signal to the remote security center 10 via the communication line.

Thus, in the remote monitoring center 10,
In the tenant building where the centralized control device 16 is installed, it is possible to recognize that an abnormality has occurred, and it is possible to quickly respond to this. The control unit 160 of the central control unit 16 transmits not only an alarm but also a security start signal to the security center 10 when a security start signal and an alarm from the common unit control device 17 are input. You may. In this way, the security center 10
So, when all tenant buildings are in security,
In other words, check whether an abnormality occurred after the tenant building became unmanned (opening of windows due to unauthorized entry, etc.) or whether the last exited person exited without checking that the common area was locked. Can be.

In the above embodiment, the control unit 181 of the tenant control unit 18 switches the operation mode to the security mode immediately after receiving the security start signal from the operation unit 180. However, when the tenant control device 18 is installed inside the tenant, when the final exit person switches the tenant control device 18 to the security mode and then opens the entrance door, the sensor installed on this door opens and closes the door. It detects and outputs a detection signal. When this detection signal is input, the tenant control device 18 outputs an alarm to the central control device 16 because the operation mode is already in the guard mode, and the tenant control device 18 transmits the alarm to the monitoring center 10 via the communication line. Unnecessary alerts are sent to the user. Therefore, the control unit 181 of the tenant control device 18 may invalidate the detection signal from the sensor installed at the entrance door of the tenant within a predetermined time after the security start signal is input from the operation unit 180. Good.

In the above-described embodiment, when the last exiting person exits the tenant building or the like and the entrance door is opened, the sensor installed on this door detects opening and closing of the door and outputs a detection signal. . Control unit 170 of common unit control device 17
When a detection signal from a sensor installed on the passage door is input while the timer 171a or 171b is counting,
The abnormal guidance is output to the notification unit 38, and a person who has confirmed this message may be confused. Therefore, the control unit 171 of the common unit control device 17 may invalidate the detection signal from the sensor installed on the passage door while the timer 171a or 171b is counting.

[0060]

According to the first aspect of the present invention, when the detection means detects an abnormality in the shared area when all of the exclusive area is in the security state, the control means sets the security state of the shared area to the security state. By issuing a message prompting inspection,
The last exit person recognizes the abnormality of the common area, and can set the common area to the optimum security state. Therefore, it is possible to prevent unnecessary warnings from being transmitted.

According to the second aspect of the present invention, the control means sets the shared area to the security state when the first predetermined time has elapsed after all the exclusive areas have been in the security state, thereby exiting. The common area can be automatically set to the security state after a predetermined time, such as the time until the person leaves, can be automatically set to the security state, and the security function of the security device can be improved.

According to the third aspect of the present invention, when the operating means is operated, the control means sets the shared area in the security state when the second predetermined time shorter than the first predetermined time has elapsed. By doing so, the time of the security release state can be shortened, and the security function of the security device can be improved.

According to the fourth aspect of the present invention, when the extension operation means is operated, the control means extends the time until the common area is switched to the security state, for example, to secure the security state of the common area. If there is an abnormality and it takes time for the exited person to cope with this and cannot exit within the first predetermined time, extend the time until the security state is set by operating the extension operation means. Since the security state of the shared area can be set to an appropriate state during the extended time, unnecessary alarm transmission can be prevented, and the security function of the security device can be improved.

According to the fifth aspect of the invention, the control means invalidates the abnormality detection by a predetermined sensor during the first, second, and third predetermined times, For example, it is possible to prevent a message prompting the user to check the security state of the common area without erroneously judging the opening of the pass-through door when the exit person exits, thereby causing confusion for the exit person.
