TECHNICAL FIELD OF THE INVENTION
The present invention relates to an alarm device that detects and reports vandalism or an intruder on a monitoring target such as a building or an office, or monitors and controls ancillary equipment of the monitoring target. In particular, it relates to an improvement of an alarm device that automatically controls equipment according to a schedule.
[0002]
[Prior art]
BACKGROUND ART Conventionally, an alarm device having a security function for monitoring an intruder or vandalism and a facility control function for monitoring and controlling incidental equipment has been put to practical use. The security function includes a state in which an abnormal alarm is issued when the intruder detection sensor detects an intruder (hereinafter, alert mode) and a state in which no alarm is issued even when an intruder is detected (hereinafter, alert release mode). ). Finally, a person who leaves the monitoring target sets the alarm device to the alert mode, and a person who first enters the monitoring target switches the alarm device to the alert release mode.
[0003]
In other words, the alert release mode is set when there is a user in the monitoring target, and the alert mode is set when there is no user. This is because it is difficult to distinguish between a user and an intruder, and an abnormal alarm is also issued when a user is detected. Therefore, an abnormal alarm is issued only when the user is not present, thereby preventing an unnecessary alarm from being issued. In the facility control function, a schedule according to a building operation is programmed in advance, and facility equipment is automatically controlled according to the control schedule.
[0004]
[Problems to be solved by the invention]
In the conventional alarm device, the security function and the facility control function each function independently. Therefore, when the user enters the building early in the morning, the alert mode is set, but the equipment is automatically operated according to the operation schedule programmed in advance. For example, there is a case where the facility control function is programmed to cause a state opposite to the current state of the facility device (if the apparatus is currently being driven, to a stop state).
[0005]
In this case, if the user enters the building earlier than the start-up time of the air conditioner, the alert release mode is set, but the air conditioner does not start. Then, the user can manually start the air conditioner. However, when the scheduled start time of the air conditioner comes, the air conditioner stops.
[0006]
As described above, when the equipment is operated according to the schedule, it is flexible according to various situations that occur on a daily basis (for example, half of the fluorescent lamp is turned off during lunchtime as part of energy saving measures). It was difficult to achieve both equipment control and automatic control based on a schedule. Accordingly, an object of the present invention is to provide an alarm device that automatically controls equipment according to a schedule and that can perform flexible equipment control when necessary.
[0007]
[Means for Solving the Problems]
The present invention stores a sensor which is installed at a predetermined security area, a mode setter for setting a predetermined security area to the desired security mode, the warning device for coupling the equipment, the control schedule of the previous SL equipment Storage means, and when set to the alert mode by the mode setting device, sets the equipment to an automatic operation mode for automatically operating according to the schedule, and when set to the alert release mode, manually sets the equipment . Control means for setting a manual operation mode to be controlled , wherein the control means cannot set the warning mode by the mode setting device when the state of the equipment does not match the state according to the schedule. providing a warning device which is characterized in that a. Further, the present invention provides an alarm device having display means for displaying that the state of the equipment does not match the state according to the control schedule .
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an example in which the present invention is applied to a security system will be described with reference to the drawings. FIG. 1 is a configuration diagram of a security system arranged in a building. Reference numeral 1 denotes an alarm device for monitoring and controlling the entire security system. The alarm device 1 processes signals from a controller of various equipment described below via a security sensor 11 for detecting an intruder, a mode setting device 12, a monitoring control line 2, and the like, and via a general public line 10. It performs notification processing to a host computer of a security center (not shown), schedule control of equipment and the like.
[0009]
The security sensors 11 are various sensors, such as a human body detection sensor, a vibration sensor, and a magnet sensor, which are installed at appropriate places inside and outside the building to be guarded and detect intruders and vandalism. When an intruder or vandalism is detected, a detection signal is transmitted to the alarm device 1 by wire or wirelessly. The mode setting device 12 is installed inside or outside near the entrance of the building, and is connected to the alarm device 1.
[0010]
Then, a signal for switching the security area in the building to the alert mode or the alert release mode is output to the alarm device 1. Switching between the alert mode and the alert release mode needs to be limited to a legitimate user in the security area from the viewpoint of crime prevention. Therefore, for example, a mode setting device 12 using a combination of a magnetic card and a card reader has been put to practical use. In this embodiment, a card reader is described as the mode setting device 12 for convenience. In addition, the security area can specify an entire building or a part of the building. Here, the entire building is defined as a security area in a security area.
[0011]
In this embodiment, the card reader reads the card data of the magnetic card carried by the user, and sends it to the alarm device 1. Then, the alarm device 1 performs comparison and collation with collation data registered in advance, and sets the security area to the alert mode or the alert release mode only when they match. In addition, an operator ID such as key-in of a personal identification number using a numeric keypad or a key switch may be used.
[0012]
The electric lock controller 3 is a device that controls locking / unlocking of the electric lock 4, receives a control signal from the alarm device 1 via the monitoring control line 2, and performs control according to the control signal. In addition, an operation confirmation signal of the electric lock 4 and a state of locking or unlocking are transmitted to the alarm device 1. The equipment controller 5 is a device that controls starting and stopping of equipment such as an air conditioner 6 and is connected to the alarm device 1 via the monitoring control line 2 like the electric lock controller 3.
[0013]
Then, when a control signal for starting, stopping or setting the temperature of the air conditioner 6 is received from the alarm device 1, control according to the signal is executed. In addition, a confirmation signal such as the operation status of the air conditioner 6 is returned to the alarm device 1 via the monitoring control line 2. Although not shown in this embodiment, various controllers according to the building, such as a lighting equipment control controller, an elevator control controller, and an equipment interlocking controller that cooperates in response to fire detection, are connected to the monitoring control line 2.
[0014]
With reference to FIG. 2, a configuration block of the alarm device 1 will be described. The CPU 20 is a central processing unit that performs arithmetic processing of various signals in the alarm device 1. The communication interface 21 is an interface that is connected to a security center (not shown) via the general public line 10 or the like and communicates with a security center or the like outside the security target. The loop check interface 22 is an interface that receives a loop check signal that is an operation signal of the confirmation button 221.
[0015]
The display interface 23 is an interface that controls display of the display 231. The switch interface 24 is an interface that receives signals from various switches such as a facility control switch 241 and a schedule input numeric key switch 242. The ROM 25 is a read-only storage unit that stores a basically non-rewriting program such as a basic operation program of the alarm device 1 and data.
[0016]
The RAM 26 is a rewritable storage unit that stores data that differs depending on the situation implemented by the customer, such as the control schedule of the equipment, the type of the connected sensor, and the installation location. The sensor interface 27 is an interface that receives a detection signal of the security sensor 11 appropriately installed on the security target. The monitoring bus interface 28 is an interface for communicating with various controllers such as the electric lock controller 3 and the equipment controller 5 via the monitoring control line 2.
[0017]
The mode interface 29 is an interface that communicates the card data transmitted by the mode setting device 12 and the comparison result. The alarm device 1 has the above-described components connected via a bus 40, and the CPU 20 controls and monitors the alarm.
[0018]
Next, the operation of the alarm device 1 configured as described above will be described with reference to FIGS. In the security system, a control schedule such as an unlocking time and a locking time of the electric lock 4 and a start time and a stop time of the air conditioner 6 is stored in the RAM 26. These data are downloaded from a communication interface 21 via a general public line 10 from a computer at a security center (not shown). Alternatively, data can be input to the RAM 26 from the switch interface 24 using the numeric key switch 242. The basic control programs for the electric lock 4 and the air conditioner 6 are stored in the ROM 25.
[0019]
FIG. 3 shows a schedule of the air conditioner 6 and the electric lock 4 stored in the RAM 26. (1) indicates that the schedule of the air conditioner 6 is set to stop at 08:50 and start at 18:00. (2) indicates that the schedule of the electric lock 4 is unlocked at 09:00 and locked at 18:00.
[0020]
Now, it is assumed that the building is unmanned and the alarm device 1 is set in the alert mode. The air conditioner 6 and the electric lock 4 are automatically operated according to a schedule. (Step 1) The operation of the security system when an employee of the building comes to work at 5:30 will be described. The employee operates the mode setting device 12 using a regular magnetic card. The mode setting unit 12 reads the card data from the magnetic card and sends the card data to the mode interface 29.
[0021]
Then, the alarm device 1 checks whether or not the input card data matches the check data stored in the RAM 26 in advance. If the collation matches and it can be confirmed that the operator is a legitimate operator, the mode information in the RAM 26 is switched from the alert mode to the alert release mode. In the alert release mode, it is not determined that the security sensor 11 is abnormal even if the security sensor 11 operates. At 5:30, the air conditioner 6 is stopped as shown in FIG. 3A, and the electric lock 4 at the front entrance is also locked. (Step 2)
[0022]
Next, after confirming that the display of the mode setting device 12 has been switched from the alert mode display to the alert release mode, the employee manually unlocks the electric lock 4 at the front entrance using a key and enters the building. When the mode is switched from the alert mode to the alert release mode by an authorized operator, the lock may be automatically unlocked in conjunction with the setting of the alert release mode. After that, the lock / unlock is manually performed until the alert mode is set.
[0023]
Then, the equipment controller 5 is manually operated to activate the air conditioner 6. Thus, even if an employee goes to work early in the morning, the air conditioner 6 can be manually controlled, so that a flexible response can be made. (Step 3) Further, in the alert release mode, no control signal is sent from the alarm device 1 to the electric lock controller 3 and the equipment controller 5. That is, since the start control signal is not sent even at 8:50 or 9:00, which is set as the start time on the schedule, the air conditioner 6 stops without permission from the employee's intention or the electric lock 4 does not work. Will not be locked.
[0024]
Next, a case where the last employee leaves at 19:00 will be described. First, the employee who is the last exit from the building pushes down the confirmation button 221. (Step 4) When the confirmation button 221 is pressed, a confirmation signal is input through the loop check interface 22. When the confirmation signal is input, it is checked whether the state of the security sensor 11 and the state of the equipment are normal. (Step 5)
[0025]
In the check of the security sensor 11, for example, in the case of a magnet sensor that detects opening and closing of a window, if the window is open, the magnet sensor detects it and the window is opened on the display 231 via the display interface 23. Is displayed. (Steps 5 and 9) In this case, when the window is closed and the confirmation button 221 is pressed again, the process proceeds to Step 6 if the other security sensor 11 has not detected the signal. If the other security sensors 11 have detected, the process does not proceed to step 6 until the detection outputs of all the security sensors 11 disappear.
[0026]
In step 6, it is checked whether the current state of the equipment matches the state on the schedule. In order to switch from manual control of the equipment in the alert release mode to automatic control based on the schedule in the alert mode, the state of the equipment at the time of switching is matched with the schedule. It is checked whether or not the equipment is in a state according to the schedule (the air conditioner 6 is in a stopped state and the electric lock 4 is in a locked state in the case of automatic operation).
[0027]
Here, if the equipment is not in a state according to the schedule, the fact is displayed on the display 231 via the display interface 23 in the same manner as in the case of the security sensor 11. (Steps 6 and 9) When the air conditioner 6 is stopped according to the display, the electric lock 4 is locked, and the confirmation button 221 is pressed again, the display disappears.
[0028]
In this way, it is confirmed that the states of all the security sensors 11 and the equipment are normal. If everything is normal, the display 231 indicates that the alert mode switching preparation is OK. (Step 7) In addition, until all is in a normal state, since it can switch to alert mode, is the state of securely equipment can match the schedule.

[0029]
When the preparation for switching to the alert mode is displayed, the employee operates the mode setting device 12 using the magnetic card possessed by the employee. The mode setting unit 12 reads the card data from the magnetic card and sends the card data to the mode interface 29. Then, the alarm device 1 checks whether or not the input card data matches the check data stored in the RAM 26 in advance. If the verifications match and the user is confirmed to be a valid operator, the mode information in the RAM 26 is switched from the alert release mode to the alert mode. (Step 8)
[0030]
In this case, at 18:00, since the alert release mode continues, the control signals to the air conditioner 6 and the electric lock 4 are not sent to the equipment controller 5 and the electric lock controller 3. That is, the electric lock 4 and the air conditioner 6 are not stopped or locked regardless of the intention of the employee.
[0031]
In the embodiment, when the security mode is set, the confirmation button 221 is pressed to check both the state of the security sensor 11 and the state of the equipment at that time according to the schedule. Alternatively, the state of the security sensor 11 may be checked by pressing the confirmation button 221, and the state of the equipment may be checked by operating the mode setting device 12. Further, both the loop state of the security sensor 11 and the state of the equipment may be determined by operating the mode setting device 12.
Needless to say, the electric lock 4 can be applied to equipment such as a shutter, an automatic door, and an elevator.
[0032]
In the present embodiment, the present invention is applied to a security system of a building, but the present invention is also applicable to an unmanned automatic store of a financial institution or a CD / ATM corner. When the present invention is applied to a security system of an unmanned store of a financial institution, the configuration and the like of the security system are almost the same as the example applied to the security system of the building described above. The only difference is that, when applied to an unmanned store of a financial institution, the watch mode is set even when the store is open.
[0033]
That is, at normal times, the unmanned store of the financial institution is automatically operated in the alert mode, and while the store is open, the security sensor 11 installed in the guest room for detecting the human body is set not to be abnormal even if a person is detected. are doing. Note that if any other abnormality of the security sensor 11 is detected during opening of the store, it is determined to be abnormal and a notification operation is performed. Switching to the alert release mode is performed at the time of store inspection or cash replenishment. At this time, even if the security sensor 11 installed in a place other than the guest room detects, the abnormality notification operation is not performed. Except for this point, the security system is the same as that of the building security system described above, and thus redundant description will be avoided.
[0034]
【The invention's effect】
It is possible to judge whether or not there is a person in the monitoring target.When a person is manned, each equipment can be controlled manually, and when there is no man, each equipment can be automatically operated according to a predetermined schedule. Flexible control is easy. In addition, when switching the control of the equipment from the manual control to the automatic control according to the schedule, the switch cannot be performed unless the state of the equipment on the schedule matches the actual state of the equipment. The situation will not be different.
