Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security system for performing security processing in a distributed manner.

[0002]

2. Description of the Related Art There are various types of security systems, one of which is a so-called local security system. Local security systems are usually built in large buildings such as large office buildings, tenant buildings, and department stores, with security guards stationed,
A security room is provided in a certain place in the building, and a center device is installed in the security room.

FIG. 10 shows a schematic configuration example of such a local security system. In FIG. 10, 1 is a control device, 2
Denotes an input device, 3 denotes a monitor, 4 to 7 denote interfaces (hereinafter referred to as I / F), and 9 denotes a center device. The control device 1 manages the operation of the security system in an integrated manner. The operation of the control device 1 will be described later. The input device 2 includes a keyboard and a mouse. The monitor 3 is composed of appropriate display means such as a color or monochrome CRT and a liquid crystal display device. The control device 1, the input device 2, and the monitor 3 constitute a center device 9. The center device 9 is usually constituted by a personal computer system, and is installed in a security room of a building where the security system is constructed.

[0004] I / Fs 4 to 7 are connected to the control device 1 via communication lines. As a communication line,
For example, a device conforming to a known standard such as RS485 and RS422 may be used.

The I / F 4 has a predetermined number of input ports, and a security sensor loop is connected to each input port. Therefore, as many security loops as the number of input ports can be connected to the I / F 4. As a security sensor,
Various sensors such as a heat ray sensor for detecting the movement of a person and an open / close detection sensor for detecting that a door or a window is opened are used, and each security sensor loop has a unique address. When the security sensor loop connected to the input port issues an alert, the I / F 4 notifies the control device 1 that the security sensor loop has issued and the address of the issued security sensor loop. Things. The operation is roughly as follows.

Now, it is assumed that there is one input loop for easy understanding. In addition, a plurality of security sensors can be connected in series to one security sensor loop. However, in order to facilitate understanding, it is assumed that one security sensor is connected to one input port. I do. By the way, since the output of the security sensor is normally performed using a normally closed relay, the electrical configuration of the I / F 4 and the security sensor in this case is as shown in FIG. FIG.
In FIG. 1, S denotes a security sensor, R denotes a relay contact of the security sensor S, 10 denotes a CPU, and V _CC denotes a power supply voltage.

In the configuration shown in FIG. 11, the CPU 10 monitors the voltage of the input port. The relay contact R of the security sensor S is normally closed as shown in the figure, and the input port is at the ground potential in this state. However, security sensor S
Opens the relay contact R for a predetermined time when the movement of the person is detected. This is an event called an alert. At this time, the voltage of the input port becomes the power supply voltage V _CC . As described above, when the CPU 10 monitors the voltage of the input port and detects that the voltage of the input port has reached the power supply voltage V _CC ,
The fact that the sensor loop of the security sensor S has issued an alarm and the address of the sensor loop of the security sensor S are notified to the control device 1 via the communication line. Thus, whether or not the security sensor loop has issued an alarm can be detected as a voltage change, but such a voltage change cannot be directly transmitted to the control device 1. Therefore, it is necessary to have a means for detecting an alarm from the security sensor loop and transmitting the data in a form recognizable by the control device 1, and the I / F 4 is provided for that purpose.

Next, the I / F 5 will be described. For example, when considering a tenant building, an electric lock may be attached to an entrance or exit of a room of each tenant or an emergency exit door. The I / F 5 controls the locking and unlocking of the electric lock provided in each of such units, and when the state of each electric lock changes, detects the change in the state and notifies the control device 1 of the change. Is what you do. There are various known methods for unlocking the electric lock by a person entering and exiting, such as a method of inputting a password with a numeric keypad and a method of inserting a card with an ID number written into a card reader. Here, it is assumed that when the card in which the ID number is written is inserted into the card reader, the locked electric lock is unlocked. The I / F 5 has a predetermined number of input ports, and an electric lock and a card reader are connected to each input port. The electric lock and the card reader are connected as one set. Each electric lock has a unique address.

The operation of the I / F 5 is roughly as follows. When a certain electric lock is locked and a card is inserted into a card reader paired with the electric lock, the card reader reads an ID number and reads the read ID.
The number is notified to the I / F 5. When receiving the ID number, the I / F 5 notifies the control device 1 of the ID number via a communication line. Upon receiving the ID number, the control device 1 determines whether the ID number is a pre-registered ID number, and ignores the ID number if the ID number is not registered. The instruction is notified to the I / F 5. As a result, the I / F 5 unlocks the electric lock. When the I / F 5 detects that the electric lock has been unlocked by the signal from the electric lock, the I / F 5 notifies the control device 1 via the communication line that the electric lock has been unlocked together with the address of the electric lock. The same applies to the case where the electric lock is locked from the unlocked state.

The I / F 5 also locks and unlocks the electric lock according to an instruction from the control device 1. For example, an emergency exit electric lock is usually locked, but it is necessary to unlock it in an emergency such as when a fire occurs. In such a case, the operator of the center device 9 instructs the simultaneous unlocking of the electric lock using the input device 2, and the simultaneous unlocking instruction is notified from the control device 1 to the I / F 5, and the I / F 5 Releases all electric locks according to the instruction. Further, the operator of the center device 9 may want to lock or unlock a specific electric lock. In such a case, the operator specifies the address of the electric lock by using the input device 2. , Locking or unlocking. This instruction is notified from the control device 1 to the I / F 5, and the I / F 5 locks or unlocks the electric lock at the address according to the instruction.

As described above, when receiving the ID number from the card reader, the I / F 5 notifies the control device 1 of the ID number. When the state of the electric lock changes, the I / F 5 notifies the control device 1 of the change. When the control device 1 instructs locking or unlocking of the electric lock, the electric lock is controlled in accordance with the instruction.

Next, the I / F 6 will be described. I / F
6 has a predetermined number of input ports, and one security state setting device is connected to each input port. Therefore,
As many security state setting devices as the number of input ports can be connected to the I / F 6. Each security status setting device has its own unique address. It should be noted that an address is usually also set in the guard area, but here, the address of the guard area is assumed to be the same as the address set in the guard state setting device that sets the guard state of the guard area.

The security state setting device is for switching the security state of the security area from the security state to the release state or vice versa. That is, the area in which the security system is constructed is divided into security areas for each appropriate unit such as each room, and security is performed for each security area. For this purpose, security status or cancellation is performed for each security area. The state needs to be set, and a security state setting device is provided for that purpose. Various methods are known as methods for setting the alert state or the release state by the security state setting device, and any method may be used.

The operation of the I / F 6 is roughly as follows. Now, assuming that a certain security area is in a guard state, and a security state setting device for setting the security state of the security area is operated and the state is switched from the guard state to the release state, the security state setting apparatus is in its own state. The I / F 6 is notified of the address and the setting of the release state. Upon receiving the notification, the I / F 6 notifies the control device 1 via the communication line of the notified address and the setting of the release state. Thereby, the control device 1 recognizes that the guard state of the guard area at the address has been switched from the guard state to the release state. The same applies to the operation when the state is switched from the release state to the alert state.

As a security status setting device, there is known a security status setting device using a magnetic card or an IC card in which an ID number is written, but this type of security status setting device. , The address of the card used at that time as well as the set security status.
The D number is also notified to the I / F 6. These information are I / F
6, the control device 1 is notified of the information. If the information is displayed on the monitor 3, it is possible to confirm which ID number of the person who has the card has performed the operation.

Next, the I / F 7 will be described. I / F
7 has a predetermined number of input ports, and one output device is connected to each input port. As the output device, a threatening device such as a buzzer or a lighting device for threatening an intruder, a transmitter for notifying various information to a security center of a security company, or the like can be used. In which case, which output device performs what kind of output is set in the control device 1 in advance. The operation of the I / F 7 will be described later.

Next, the overall operation of the security system shown in FIG. 10 will be schematically described. Here, I / F7
Is connected to a threatening device and a transmitter as an output device, and the control device 1 is set to operate the threatening device when an abnormality occurs and to notify the security center of the security company of the abnormality. It is assumed that In addition, the correspondence between the address of the security area and the address of the security sensor loop indicating which security sensor loop of which address is installed in the security area of which address, and the electric lock of which address is installed in the security area of which address The correspondence between the address of the warning area and the address of the electric lock is registered in the control device 1 in advance.

The control device 1 determines whether each guard area is currently in a guard state by the information notified from the I / F 76.
It recognizes whether it is in the release state. On the other hand, the security sensor is always in operation. When the security sensor is a hot-wire sensor, the alarm is issued every time a person's movement is detected. When the security sensor is an open / close detection sensor, the door or window is opened. An alert is issued each time it is received. These alarms are sent from the I / F 4 to the controller 1
Every time the control device 1 receives the notification of the alarm from the I / F 4, the control device 1 determines whether the guard area in which the security sensor loop is installed is in the alert state or in the released state. If it is in the released state, the alarm is ignored, but if it is in the alert state, it is determined that an abnormality has occurred, and the occurrence of the abnormality is displayed on the monitor 3 together with the address of the alert area. In addition, the I / F 7 is notified of a command for instructing the operation of the intimidating device and a command for reporting an abnormality to the security center. As a result, the I / F 7 operates the intimidating device and instructs the transmitter to notify the abnormality, so that the intimidating device operates and the transmitter notifies the security center of the abnormality.

Each time the electric lock is locked or unlocked, the control device 1 is notified of information about the state of the electric lock from the I / F 5. It is determined whether the guard area where the lock is installed is in the guard state or in the released state, and if it is in the released state, it only recognizes the state of the notified electric lock, but it is in the guard state In this case, it is determined that an abnormality has occurred, and the occurrence of the abnormality is displayed on the monitor 3 together with the address of the alert area, and a command for instructing the I / F 7 to operate the intimidating device, and a security center Notify the error notification command to As a result, the I / F 7 operates the intimidating device and instructs the transmitter to notify the abnormality, so that the intimidating device operates and the transmitter notifies the security center of the abnormality.

When the operator of the center device 9 wants to lock or unlock a specific electric lock, or when it is necessary to unlock all electric locks simultaneously,
The input device 2 indicates the address of the electric lock to instruct locking or unlocking, or to perform simultaneous unlocking.
This instruction is notified from the control device 1 to the I / F 5, and the I / F 5
Based on this instruction, 5 instructs locking or unlocking of the electric lock at the designated address, or instructs all electric locks to unlock.

[0021]

As is apparent from the above description, in the conventional security system, all information from the security sensor loop, the electric lock, and the security status setting device is collected in the control device 1 of the center device 9. The control device 1 intensively performs processing related to security such as whether or not an abnormality has occurred. That is, the conventional security system can be said to be a centralized security system.

However, in the conventional centralized security system, security related processes are collectively performed by the control device 1, so that the number of security sensor loops, electric locks, and security status setting devices is extremely large. In such a case, a large amount of information is notified to the control device 9, and a large amount of information may be notified within a short time. In such a case, the processing load on the control device 1 becomes large, so that the processing related to security takes time, and even if an abnormality occurs, it may not be possible to immediately detect the occurrence of the abnormality. There is. Further, if a large amount of information is concentrated on the control device 1 at one time, the control device 1 may go down and cause a system down of the center device. There is also a problem that the operation cannot be performed.

Therefore, the present invention is particularly suitable for application to a local security system, which can reduce the processing load on the center device and can perform minimum security even if the center device goes down. The purpose is to provide a security system that can be used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, it is assumed that a security system is constructed in a tenant building.

FIG. 1 is a view showing an embodiment of a security system according to the present invention. In FIG.
Denotes a terminal control unit, 40 denotes a terminal unit, 50 denotes a terminal control unit, 60 denotes a terminal unit, 70 denotes a terminal control unit, 80 denotes a terminal unit, 90 denotes a terminal control unit, and 100 denotes a terminal unit. Note that the same components as those shown in FIG. 10 are denoted by the same reference numerals.

The center device 9 is connected to the master control unit 20 via a communication line, and can exchange information with each other. The configuration of the master control unit 20 will be described later. As a communication line, for example, RS485, RS42
2. A device conforming to a known standard such as RS232C may be used. The same applies to the communication line below. The master control unit 20 has a predetermined number of input ports, and a terminal control unit is connected to each input port via a communication line. In FIG. 1, the master control unit 20 includes four terminal control units 3.
0, 50, 70, and 90 are connected, but this is only an example. Each terminal control unit has
A predetermined number of terminal units can be serially connected via a communication line, and a predetermined number of terminal units can be connected to each terminal unit.

Hereinafter, the terminal control unit, the terminal unit, and the terminal will be described.
Is a security control unit, the terminal control unit 50 is an electric lock control unit, the terminal control unit 70 is a tenant control unit, and the terminal control unit 90 is an output control unit. Therefore, in the following, the terminal control unit 30 will be referred to as the security control unit 30. Regarding the terminal control units 50, 70, and 90, respectively, the electric lock control unit 50, the tenant control unit 7
0, that is, the output control unit 90.

First, the security control unit 30 will be described.
The security control unit 30 is installed in a security room of a building where the security system is constructed. This security control unit 30
Performs processing related to security of the common part of the tenant building. That is, in the tenant building, there are areas shared by the tenants, such as passages, stairs, and lobbies, in addition to the rooms of each tenant, and it is necessary to provide security for these areas. Therefore, a security sensor loop is also installed in the common area, and it is provided to perform processing related to security whether the security sensor loop installed in these common areas is abnormal or not when an alarm is issued. This is the security control unit 30.

FIG. 2 shows an example of the configuration of the security control unit 30. The security control unit 30 includes a CPU 31, an input unit 32, and a display unit 33.
It has. The input unit 32 is provided so that the security state of each guard area of the common unit can be switched from the guard state to the release state, or vice versa, even when the center device 9 is down. It is provided with a numeric keypad for inputting an address or the like of a guard area of the common unit, a guard button, a release button, a registration button, and the like necessary for setting a guard state. The display unit 33
This is for displaying information input when the security state of the security area of the common area is set by the input unit 32, and is constituted by appropriate display means such as a liquid crystal display (LCD). Note that if an LCD having a touch panel is used, the input unit 32 and the display unit 33 can be integrally configured.

The CPU 31 has a predetermined number of input ports. Here, for ease of understanding, it is assumed that there is one input port as shown in FIG. And C
A predetermined number of terminal units 40 are serially connected to an input port of the PU 31 via a communication line, and a predetermined number of terminal devices can be connected to each terminal unit 40. Each of these terminals has a unique address. The correspondence between the address of the guard area and the address of the terminal indicating which address of the terminal is located in the guard area of which address is determined in advance by the CPU 3.
1 registered.

The terminal connected to the terminal unit 40 connected to the security control unit 30 is a security sensor loop. Therefore, the terminal unit 40 determines whether or not the security sensor loop has issued by issuing the same configuration as that shown in FIG. 11, that is, by monitoring the voltage of the input port to which the security sensor loop is connected. In this case, a configuration is provided in which the terminal control unit 30 can be notified of the alarm from the security sensor loop and the address of the security sensor loop via a communication line.

As described above, the CPU 31
Assuming that two terminal units 40 can be connected, and each terminal unit 40 can be connected to 20 security sensor loops, a total of 120 security sensor loops can be arranged in the common area. . Therefore, CPU3
If there are a plurality of one input ports, it is possible to arrange as many security sensor loops as there are. Similarly, if a plurality of security control units 30 are connected to the master control unit 20, more security sensor loops can be arranged.

Next, the operation of the security controller 30 will be described. By the way, the security status of the common unit is usually the center device 9
Is set by the operator. As will be described later, when the security status of each tenant is switched from the alert status to the release status, or vice versa, all the information is notified from the tenant control unit 70 to the master control unit 20, and furthermore, the master control unit 20 notifies the control device 1 of the center device 9 and displays it on the monitor 3. Therefore, the operator of the center device 9 can know whether each tenant is currently in the alert state or in the released state. Therefore, for example, when all the tenants on a certain floor are in the alert state, the operator sets the alert state for the alert area of the floor by the input device 2. In the morning, when the working time is about to start, the operator sets all the guard areas in the common unit to the release state by using the input device 2.

As described above, the security state of the guard area of the common unit is set by the center device 9 because the area of each tenant is independently managed by each tenant, but the common unit is not. Since it is inconvenient for the security state to be set arbitrarily, it is performed on the center device 9 side.

When the security status of the common unit is set by the input device 2, the control device 1 fetches and stores the security status, and notifies the master control unit 20 of the set content. The master control unit 20 stores the information and notifies the CPU 31 of the security control unit 30. And CPU3
1 remembers it. By the above operation, the CPU 31 of the security control unit 30 recognizes whether each guard area of the common unit is in the guard state or the cancel state. In addition, the master control unit 20 also recognizes whether each guard area of the common unit is in a guard state or a cancel state.

The terminal unit 40 monitors the connected security sensor loop, and when detecting that the alarm has been issued, the terminal unit 40 sends the issued security sensor address to the C of the security control unit 30.
Notify PU31. Upon receiving the notification of the alarm from the terminal unit 40, the CPU 31 determines whether the security area in which the security sensor loop is installed is currently in the alert state or in the released state. The alarm is ignored, but when the user is in the alert state, it is determined that an error has occurred, and the occurrence of the error, the address of the alarm sensor loop that issued the alarm, and the address of the alert area are notified to the master control unit 20. . The master control unit 20 stores the information and notifies the control device 1 of the center device 9.

Upon receiving these pieces of information, the control device 1
The received information is stored, and the occurrence of the abnormality and the address of the alert area are displayed on the monitor 3. This allows the operator of the center device 9 to know in which alert area the abnormality has occurred.

As described above, the security state of the guard area of the common area is normally set by the center device 9 and the security state is notified to the master control section 20 and further to the security control section 30. The center device 9 for some reason
If the system goes down, it will not be possible to set the security status of the common unit. Therefore, as described above, the security control unit 30 is provided with the input unit 32 and the display unit 33 so that the security state of the common unit can be set even when the center device 9 goes down. Therefore,
When the center device 9 is down, the security status can be set, for example, by the input unit 32 for each address of the security sensor loop or for each security area. That is, the input unit 32 is provided as a backup when the security state of the common unit cannot be set by the center device 9. It is to be noted that only the security room operator can operate the input unit 32 of the security control unit 30 to set the security state of the common unit.

The security status set by the input unit 32 is the CPU
31. The CPU 31 stores the information and notifies the master control unit 20 of the information. Master control unit 2
0 stores this information and notifies the control device 1. When the system of the center device 9 is down, the control device 1 does not receive this information. By the above operation, even when the system of the center device 9 goes down, security of the common unit can be performed.

As described above, regarding the security of the common unit, the security control unit 30 performs the security processing conventionally performed by the center device, so that the processing load of the control device 1 of the center device 9 is reduced. can do. In addition, even when the system of the center device goes down, security of the common unit can be performed.

Further, in the prior art, all the alarms of the security sensor loop were notified to the control device of the center device. In this security system, however, the security control unit 30 sends the control device 1 via the master control unit 20. Will be notified
Usually, only the information on the occurrence of the abnormality is present, so that the communication traffic of the information is also reduced as compared with the conventional case.

Next, the electric lock control unit 50 will be described. This electric lock control unit 50 is also installed in a security room of a building where the security system is constructed. The electric lock control unit 50 performs processing related to the electric lock attached to the door of the common part of the tenant building. That is, as described above, the tenant building has a common area, and the common area may be provided with a door such as an emergency exit,
An electric lock may be attached to the door of such a common part. Therefore, a device for controlling the electric lock provided in the common unit is required, and this is the electric lock control unit 50. Here, it is assumed that the electric lock can be unlocked also by inserting the card in which the ID number is written into the card reader.

FIG. 3 shows an example of the configuration of the electric lock control unit 50.
The electric lock control unit 50 includes a CPU 51, an input unit 52, and a display unit 53. The input unit 52 and the display unit 53 will be described later. The CPU 51 has a predetermined number of input ports. Here, for ease of understanding, it is assumed that there is one input port as shown in FIG. And CP
A predetermined number of terminal units 60 are serially connected to the input port of U51 via a communication line, and a predetermined number of terminal units can be connected to each terminal unit 60. Each of these terminals has a unique address. Further, in the CPU 51, the correspondence between the electric lock of which address is connected to which terminal unit 60 is registered in advance.

In this case, the terminals connected to the terminal unit 60 are an electric lock and a card reader. FIG. 4 shows a configuration example of the terminal unit 60. The terminal unit 60 includes a CPU 61, and a predetermined number of card readers and electric locks are connected to the CPU 61. That is, the card reader and the electric lock are provided as one set. Here, for ease of understanding, it is assumed that one terminal unit 60 can be connected to one set of a card reader and an electric lock. An ID number is registered in the CPU 61 in advance.

As described above, the electric lock control unit 50
Assuming that 15 terminal units 60 can be connected to the common unit, 15 sets of card readers and electric locks can be arranged in the common unit. Therefore, C of the electric lock control unit 50
If there are a plurality of input ports of the PU 51, a large number of sets of card readers and electric locks can be arranged. Similarly, the electric lock control unit 50 is
When a plurality of card readers and electric locks are connected, more sets of card readers and electric locks can be arranged.

Next, the electric lock control unit 50 and the terminal unit 6
The operation of 0 will be described. Control of locking and unlocking of the electric lock installed in the common unit can be performed automatically according to a time schedule, can be performed manually by the operator of the center device 9, or the ID number is written. It can also be performed using a card.

First, the case where the automatic operation according to the time schedule is performed will be described. In a tenant building, the electric locks of the common use unit may be unlocked at any time in the morning and individually at any time in the afternoon, simultaneously or individually. In such a case, the electric lock of the common unit may be automatically locked and unlocked by registering a time schedule in advance.

The time schedule is set by the center device 9. That is, the operator sets the time of unlocking and the address of the electric lock, the time of locking and the address of the electric lock using the input device 2, and registers them in the control device 1. The reason why the time schedule for controlling the electric lock of the common unit is set on the center device 9 is for the same reason as the setting of the security state of the common unit on the center device 9 side.

The control device 1 registers the time schedule set by the input device 2, and
Notify. The master control unit 20 registers the notified time schedule, and performs an automatic operation process of the electric lock based on the time schedule. Therefore, assuming that the unlock time and the lock time are registered for the electric lock at a certain address, the master control unit 20 sends the unlock time to the CPU 51 of the electric lock control unit 50 when the unlock time comes. Give the address of the electric lock and instruct unlocking. Upon receiving this instruction, the CPU 51 instructs the CPU 61 of the terminal unit 60 to which the electric lock is connected to unlock. Thereby, the electric lock is unlocked.

In this way, the electric lock is unlocked. At this time, the CPU 61 of the terminal unit 60
The unlocking is detected by a signal from the electric lock. Then, the CPU 61 notifies the CPU 5 of the electric lock control unit 50 that the electric lock has been unlocked with the address of the electric lock.

Next, the case of going in and out using a card will be described. Now, a case in which the locked electric lock of the common unit is unlocked to enter the tenant building will be described. At this time, a person trying to enter the building inserts a card into the card reader. When the card is inserted, the card reader reads the ID number from the card and notifies the CPU 61 of the terminal unit 60 of the read ID number. The CPU 61 determines whether or not the notified ID number is a registered ID number. If the registered ID number is not registered, the CPU 61 does nothing. Unlock. When the unlocking is detected by a signal from the electric lock, the CPU 6

, The operator can know which ID number the electric lock has been unlocked.

When the electric lock is of a type that is automatically locked a certain time after unlocking, it is locked a certain time after unlocking, as described above. When the CPU 61 detects that the electric lock has been locked by a signal from the electric lock, the CPU 51 of the electric lock control unit 50 gives the address of the electric lock and indicates that the electric lock is locked.
Notify. Then, as described above, this information is sent from the CPU 51 of the electric lock control unit 50 to the master control unit 20.
Further, the master control unit 20 notifies the control device 1.

As described above, the electric lock installed in the common unit can be controlled from the center device 9 all at once or individually.
If the system goes down, it becomes impossible to control the electric lock of the common part. Therefore, the electric lock control unit 50 is provided with an input unit 52 and a display unit 53 so that the electric lock of the common unit can be controlled even when the center device 9 goes down.

The input unit 52 includes a numeric keypad for inputting the address of the electric lock to be controlled and the like, and buttons for setting whether to unlock or lock. The display unit 53 is for displaying information input when the control of the electric lock of the common unit is set by the input unit 52, and is configured by an appropriate display means such as an LCD. LCD with touch panel
Is used, the input unit 52 and the display unit 53 can be integrally configured.

Therefore, for example, when it is necessary to control a certain electric lock when the system of the center device 9 goes down, the address of the electric lock to be controlled and whether or not the electric lock is to be unlocked are determined by the input unit 32. What is necessary is just to set the mode of control whether to lock.

The contents set by the input section 52 are
It is taken in. Then, the CPU 51 interprets the set contents and instructs the CPU 61 of the terminal unit 60 to which the electric lock of the set address is connected to unlock or lock.

By the above operation, even when the system of the center device 9 goes down, the electric lock of the common unit can be controlled. That is, the input unit 52 is provided as a backup when the control of the electric lock of the common unit cannot be performed from the center device 9. In addition,
Only the operator in the security room can operate the input unit 52 of the electric lock control unit 50.

As described above, the electric lock control unit 50
CPU 51 normally only controls the communication between each terminal unit 60 and the master control unit 20. When the control of the electric lock is set by the input unit 52, the CPU 51 That is, the process is performed.

As described above, with respect to the control of the electric lock of the common unit, the electric lock control unit 50 performs most of the processing conventionally performed by the center device. Burden can be reduced. Further, even when the system of the center device goes down, the electric lock of the common unit can be controlled.

Next, the tenant control unit 70 and the terminal unit 80 connected to the tenant control unit 70 will be described. The tenant control unit 70 is installed in a security room of the building where the security system is constructed, while the terminal unit 80 is installed near the area of each tenant.

A predetermined number of terminal units 80 can be connected to the tenant control unit 70. A predetermined terminal device is connected to each terminal unit 80. The terminal unit 80 is for performing processing related to security of each tenant and controlling the electric lock. Therefore, a security sensor loop, a security state setting device, and an electric lock are connected to the terminal unit 80. Therefore, regarding this terminal unit 80,
The security sensor loop, the security state setting device, and the electric lock are terminals. The electric lock is attached to the door of the entrance of each tenant, the security state setting device is attached near the entrance of each tenant, and the security sensor loop is installed in the security area of each tenant.

The security status setting device switches the security status of the security area of the tenant from the security status to the release status, or vice versa. Here, the card with the ID number written therein is inserted into the card reader. It is assumed that the security state is set by pressing a warning button or a release button.

FIG. 5 shows a configuration example of the tenant control unit 70, and FIG. 6 shows a configuration example of the terminal unit 80. The tenant control unit 70 includes a CPU 71, and the terminal unit 8
A predetermined number of input ports to which 0 is connected are provided. Here, for ease of understanding, it is assumed that there is one input port as shown in FIG. A predetermined number of terminal units 80 can be serially connected to the input port of the CPU 71 via a communication line.

As shown in FIG. 6, the terminal unit 80
U81, and the CPU 81 has, as a terminal device,
The security sensor loop, the security status setting device, and the electric lock are connected. The number of these security sensor loops, security state setting devices, and electric locks that can be connected is arbitrary. However, in order to facilitate understanding, FIG.
As shown in, security sensor loop, security status setting device,
It is assumed that one electric lock can be connected. A unique address is defined for each of the security sensor loop, security state setting device, and electric lock as these terminals. In the CPU 81, an ID number valid in the security state setting device is registered. Also,
In the CPU 71 of the tenant control unit 70, the security sensor loop, the security state setting device, and the electric lock of which address are
Which terminal unit 80 is connected and the correspondence between them is registered in advance.

As described above, for example, assuming that 15 terminal units 80 can be connected to the tenant control unit 70, only one tenant control unit 70 is used in a tenant building where the number of tenants is 15 or less. Control unit 20
If the number of tenants is 16 or more and 30 or less, two tenant control units 70 may be connected to the master control unit 20.

Next, the operation will be described. Now, let's say that the security area of a certain tenant is set to be in a security state,
It is assumed that a related person of the tenant is about to switch from the alert state to the released state and enter the room. At this time, the electric lock of the tenant is locked.

The concerned person first inserts the card into the card reader of the alert state setting device and presses the release button. The card reader reads the ID number from the card,
Notify. When the CPU 81 receives the ID number,
It is determined whether or not the D number is registered. If the D number is not registered, the alert button is ignored and the alert state is maintained. If the ID number is registered, C
The PU 81 validates the operation of the release button, sets the release state, and unlocks the electric lock. And the CPU 81
When detecting that the tenant has been unlocked by a signal from the electric lock, the information is stored, the security area of the tenant is set to the released state, the ID of the card used in the security state setting device, The number and the unlocking of the electric lock are notified to the CPU 71 of the tenant control unit 70 by attaching the addresses of the security state setting device and the electric lock.

When receiving this information, the CPU 71 of the tenant control unit 70 stores the information and notifies the master control unit 20 of the information. The master control unit 20 stores the information received from the CPU 71 and notifies the control device 1 of the center device 9 of the information. The control device 1 stores the information. Therefore, by displaying the information on the monitor 3, it is possible to know which tenant has been released and that the electric lock of that tenant has been unlocked. As described above, the CPU 81 of the terminal unit 80 controls locking and unlocking of the electric lock in conjunction with switching of the security status by the security status setting device.

The CPU 81 of the terminal unit 80 monitors the connected security sensor loop, and since the security sensors constituting the security sensor loop are operating at all times, the heat ray sensor is used for the movement of a person. Is detected, the open / close detection sensor emits a notification when the attached door or window is opened, and the CPU 81 detects these notifications. However, when the alert area is set to the release state, Does not perform any processing ignoring the CPU 81.

After that, when the business hours of the tenant are finished and the final leaver leaves the room of the tenant, the final leaver inserts the card into the card reader of the alert state setting device and presses the alert button. Push. The card reader reads the ID number from the card and notifies the CPU 81. When receiving the ID number, the CPU 81 determines whether or not the ID number is registered. If the ID number is not registered, the CPU 81 ignores the release button and maintains the release state. ID
If the number is registered, the CPU 81
Activates the operation of the alert button, sets the alert state, and locks the electric lock. When the CPU 81 detects that the lock has been performed by the signal from the electric lock, the CPU 81 stores the information, that the security area of the tenant has been set to the security state, and that the card used by the security state setting device has been set. The ID number and the lock of the electric lock are notified to the CPU 71 of the tenant control unit 70 by attaching the addresses of the security state setting device and the electric lock.

When receiving this information, the CPU 71 of the tenant control unit 70 stores the information and notifies the master control unit 20 of the information. The master control unit 20 stores the information received from the CPU 71 and notifies the control device 1 of the center device 9 of the information. The control device 1 stores the information. Therefore, if the information is displayed on the monitor 3, it is possible to know which tenant is in the alert state and that the electric lock of the tenant has been locked.

When the CPU 81 of the terminal unit 80 detects that the security sensor loop has issued the alert when the security area of the tenant is alert, it determines that an error has occurred and stores the information on the occurrence of the error. At the same time, the CPU 71 of the tenant control unit 70 is notified of the occurrence of the abnormality with the address of the security sensor loop. CPU7
1 stores the information and notifies the master control unit 20 of the information. The master control unit 20 stores the information received from the CPU 71 and notifies the control device 1 of the center device 9 of the information. The control device 1 stores the information and displays the information on the monitor 3. Therefore, the operator of the center device 9
You can find out which tenant failed.

As described above, when an emergency such as a fire occurs, the central device 9 locks the electric lock,
You may be instructed to unlock. The instruction is set by the input device 2 of the center device 9, is notified from the control device 1 to the master control unit 20, and is further notified from the master control unit 20 to the CPU 71 of the tenant control unit 70.
U71 notifies the CPU 81 of the terminal unit 80 managing the electric lock of the designated address of the instruction. C
The PU 81 locks or unlocks the electric lock according to the instruction. When the CPU 81 detects that the electric lock is locked or unlocked by a signal from the electric lock, the CPU 81 notifies the CPU 71 of the tenant control unit 70 of the lock or unlock of the electric lock by attaching the address of the electric lock. . Thereafter, as described above, the information is notified from the CPU 71 to the master control unit 20 and from the master control unit 20 to the control device 1 of the center device 9.

Further, data necessary for processing may be downloaded from the center device 9 to the CPU 81 of the terminal unit 80 in some cases. For example, when a new tenant moves in, an ID number used by the card reader of the security state setting device of the tenant is newly determined, but the data of this ID number needs to be registered in the CPU 81 of the terminal unit 80. There is. In such a case, the operator of the center device 9 sets the data to be downloaded, and designates the terminal unit 80 to be downloaded, and issues a download instruction. Thereby, control device 1 notifies master control unit 20 of these pieces of information. Upon receiving this, the master control unit 20 transmits the information to the tenant control unit 70
To the CPU 71. Upon receiving the information, the CPU 71 passes the data to be downloaded to the specified terminal unit 80 and instructs the terminal unit 80 to register. Thereby, the CPU 81 of the terminal unit 80 newly registers the data.

As described above, the processing relating to the security of the tenant is performed by the terminal unit 80, and the tenant control unit 70 communicates with the terminal unit 80 and the master control unit 2
It just communicates with 0. That is, the tenant control unit 70 merely mediates communication between the master control unit 20 and the terminal unit 80. Therefore, it is conceivable that the terminal unit 80 is directly connected to the master control unit 20. However, in such a case, the burden on the master control unit 20 increases, so the tenant control unit 70 is provided, and the terminal unit The tenants are connected to each other, and information on security of the tenant from each terminal unit 80 is collected by the tenant control unit 70 and notified to the master control unit 20.

The security status of the security area of the tenant can be set only by the security status setting device installed in each tenant, and the security status of the security area of each tenant can be set from the center device 9 side. Can not. This is because the area of each tenant is managed independently by each tenant, and even the operator of the center device 9 is not allowed to set the security state of the security area of each tenant. However, in consideration of the case where an emergency such as a fire occurs as described above, the electric lock of the door at the entrance of each tenant is controlled by the center device 9.
Locking and unlocking can be controlled.

As described above, regarding the security of each tenant, all the processing related to security, which was conventionally performed by the center device, is performed by the terminal unit 80.
The processing load on the control device 1 can be reduced. In addition, processing related to security of each tenant is performed by the terminal unit 80.
Therefore, security of each tenant can be performed even when the center device 9 goes down. Further, if the communication between the tenant control unit 70 and the master control unit 20 or the communication between the terminal unit 80 and the tenant control unit 70 cannot be performed for any reason, if the terminal unit 80 is operating, The setting of the security state and the control of the electric lock linked thereto are performed normally.

Next, the output control unit 90 and the output control unit 9
The terminal unit 100 connected to 0 will be described.
Both the output control unit 90 and the terminal unit 100 are installed in a security room of a building where the security system is constructed.

As described above, in this security system, the security of the common unit is controlled by the security control unit 30, the terminal unit 40 connected to the security control unit 30, and the terminal connected to the terminal unit 40. It is performed by a certain security sensor loop system, and the control of the electric lock of the common unit is performed by the electric lock control unit 5.
0, a terminal unit 60 connected to the electric lock control unit 50,
The security of the tenant area is performed by the system of the electric lock which is a terminal device connected to the terminal unit 60, and the tenant control unit 70, the terminal unit 80 connected to the tenant control unit 70, and the terminal unit 80 connected to the tenant control unit 70. The information is sent from the security sensor loop, the security status setting device, and the electric lock system which are the terminal devices, and the information from the terminal units 40, 60, and 80 of each system is transmitted to the security control unit 30, the electric lock control unit 50, and the tenant control unit, respectively. The information is notified from 70 to the master control unit 20, further from the master control unit 20 to the center device 9, and displayed on the monitor 3 as necessary.

In a security system constructed in a building where a security guard is resident as expected by the security system, the security guard can immediately rush to the site if any abnormality occurs. However, when a specific event occurs, there is a case where the user wants to output not only to the monitor 3 of the center device 9 but also to an appropriate external device. For example, when an abnormality occurs, it is desirable to intimidate the intruder with a threatening device such as a buzzer or a bell, or to notify the security company of the abnormality, or when the security state of a specific security area is changed. In some cases, it may be desirable to report to a security company.

As described above, when a specific event occurs, it may be desirable to notify a security company or to operate an external device such as a threatening device.
The output control unit 90 and the terminal unit 100 are provided for outputting a predetermined signal to an appropriate external device. Therefore, these external devices are connected to the terminal unit as terminals. The output control unit 90 includes a predetermined number of terminal units 10.
Although 0 can be connected, it is assumed here that only one terminal unit 100 can be connected as shown in FIG.

FIG. 7 shows a configuration example of the output control section 90, and FIG. 8 shows a configuration example of the terminal unit 100. The output control unit 90 includes a CPU 91 that receives the information notified from the master control unit 20 and notifies the terminal unit 100 of the information received from the master control unit 20.

The terminal unit 100 has a CPU 101 and an output port 102. The CPU 101 receives the information notified from the CPU 91 of the output control unit 90,
Output is performed based on the information. Output port 1
02 has a predetermined number of output terminals. These output terminals may be relay output terminals or terminals capable of outputting data in a predetermined form.

The kind of event that occurs and from which output terminal of the output port 102 a signal is output is set by the center device 9 and registered in the master control unit 20 in advance. Then, the master control unit 20 controls the security control unit 3
0, when the information is notified from the electric lock control unit 50 and the tenant control unit 70, it is determined whether or not the event is a set event, and if the event is set, the output control unit 90 is set. , A signal to be output and an output terminal of the output port 102 to be output are specified. CPU of output control unit 90
When receiving the instruction from the master control unit 20, the 91 notifies the CPU 101 of the terminal unit 100 of the instruction.
Then, the CPU 101 outputs the specified signal to the designated output terminal of the output port 102. As a result, a predetermined signal is output from the preset output terminal.

Next, a specific example of the operation will be described. Here, the output port 1 of the terminal unit 100 is used as a terminal.
A notification device is connected to the No. 02 output terminal, and when a security sensor loop in a guarded area in a guarded state issues a notification, the setting for performing an abnormality notification to a security company by the notification device is sent to the master control unit 20. It shall be registered.

When the master control unit 20 receives information from the security control unit 30, the electric lock unit 50, and the tenant control unit 70, the master control unit 20 determines whether or not the event is set, that is, the security control of the security area in the security state. It is determined whether or not the information is that the sensor loop has issued an alarm, and if it is determined that the received information is a set event, the address of the security sensor loop that has issued the alarm is sent to the output control unit 90. The data of the attached abnormality report is given, and an output to the first output terminal of the output port 102 is specified.

The CPU 91 of the output control section 90 notifies this instruction to the CPU 101 of the terminal unit 100. Then, the CPU 101 outputs abnormality notification data to the first output terminal of the output port 102. The data of the abnormality report is taken into the reporting device connected to the first output terminal of the output port 102, and is reported to the security company.

As described above, the output control unit 90,
By using a terminal unit 100 and an appropriate external device as a terminal, when a desired event occurs,
A predetermined signal can be output to an external device. Also,
Regarding the output processing, the center device 9 is the master control unit 2
Since only the contents to be registered to 0 are set, and all the processes of output to the actual external device are performed by the master control unit 20,
The processing load on the control device 1 of the center device 9 is reduced as compared with the related art. Further, even when the system of the center device 9 is down, it is possible to output to an external device.

Next, the master control unit 20 will be described. The master control unit 20 is also installed in a security room of a building where the security system is constructed. As is clear from the above description, in the security system shown in FIG. 1, the master control unit 20 receives information from the terminal control units of the security control unit 30, the electric lock control unit 50, and the tenant control unit 70. A process of storing the information and notifying the center device 9, a process of receiving information from the center device 9 to each terminal control unit and notifying the designated terminal control unit, and being connected to the terminal unit 100. It performs processing such as output processing to the terminal device.

FIG. 9 shows an example of the configuration of the master control unit 20. The CPUs 22 to 25 are input ports to which the terminal control unit is connected. The CPUs 22 to 25 communicate with the CPU of the connected terminal control unit to exchange information. Note that FIG.
Although the number of input ports is four, this is merely an example, and may be more or less than four.
Here, the security control unit 30 is connected to the CPU 22,
An electric lock control unit 50 is connected to the CPU 23 and the CPU 2
4 is connected to a tenant control unit 70, and the CPU 25 is connected to an output control unit 90.

Hereinafter, although overlapping with the above description, an example of the operation will be briefly described. Now, assuming that the security control unit 30 has notified the information of the occurrence of the abnormality, the CPU 22 receives the information and passes it to the CPU 21. Upon receiving the information from the CPU 22, the CPU 21 stores the information in a memory (not shown) and notifies the control device 1 of the center device 9 of the information. CPU2
1 has a calendar function and a timer function, and when storing information, adds the date and time to the information to be stored. Further, since the information notified from the security control unit 30 is information on occurrence of an abnormality, the CPU 21 sounds the buzzer 27 at this time. Thereby, the guard in the security room can know that the abnormality has occurred.

When the control device 1 of the center device 9 notifies the information of the change of the security status of the guard area of the common unit, the CPU 21 stores the information in the memory with the date and time. Pass the information to At this time, it is natural that the address of the guard area for changing the guard state is also notified. As a result, the information becomes C
The security control unit 30 is notified from the PU 22 and the security state of the security area is changed.

Next, it is assumed that the electric lock control unit 50 notifies information that an electric lock has been locked or unlocked.
At this time, the address of the electric lock and the ID number of the used card are also notified as described above. This information is received by the CPU 23. Then, the CPU 23 receives the information and passes it to the CPU 21. When receiving the information from the CPU 23, the CPU 21 stores the information in a memory with a date and time, and notifies the control device 1 of the center device 9.

When information of locking or unlocking of the electric lock of the common part is notified from the control device 1 of the center device 9, the CPU 21 stores the information in a memory with date and time. Pass the information to At this time, it is natural that the address of the electric lock to be locked or unlocked is also notified. As a result, the information is stored in the CPU
23 notifies the electric lock control unit 50, and further notifies the terminal unit 60 that manages the electric lock of the address from the electric lock control unit 50. As a result, the electric lock is locked or unlocked.

Next, when information indicating that the security state has been changed, information indicating that an abnormality has occurred, or information indicating that the electric lock has been locked or unlocked is notified from the tenant control unit 70, these information are sent to the CPU 24. Received. And
The CPU 24 passes the received information to the CPU 21. CPU
21 stores the information with the date and time and notifies the center device 9. If the received information is information on occurrence of an abnormality, the CPU 21 causes the buzzer 27 to sound. Thereby, the guard in the security room can know that the abnormality has occurred.

When information indicating locking or unlocking of the electric lock of a certain tenant is notified from the control device 1 of the center device 9, the CPU 21 adds the date and time to the information and stores it in the memory. Then, the information is passed to the CPU 24. At this time, it is natural that the address of the electric lock to be locked or unlocked is also notified. Thus, the information is notified from the CPU 24 to the tenant control unit 70, and further transmitted from the tenant control unit 70 to the terminal unit 80 that manages the electric lock at the address. As a result, the electric lock is locked or unlocked.

Next, the event to be output from the center device 9 to the terminal device and the case where the output terminal of the output port to output at that time is specified are as follows. At this time,
The CPU 21 stores the specified contents in a predetermined file (not shown). When the information received from the security control unit 30, the electric lock control unit 50, and the tenant control unit 70 indicates an event to be output, the content of the event and the date and time of occurrence are stored in a memory. With reference to the file, a signal to be output is passed to the output control unit 90.
At this time, it is natural that the output terminal for outputting the signal is specified. As a result, the signal is output to the output control unit 9.
0 to the terminal unit 100 and the terminal unit 10
0 is output to the designated output terminal of the output port 102 and is input to the terminal connected to the output terminal.

Since all information stored in the CPU 21 of the master control unit 20 is shared by the control device 1 of the center device 9, a printer (not shown in FIG. 1) is provided in the center device 9.
Can be viewed to see what date and time and what kind of event has occurred, but if the center device 9 is down, printing cannot be performed. Therefore, the master control unit 20 shown in FIG.
Is provided with a printer 28 as a backup when printing cannot be performed on the side of the center device 9, and information stored in the memory of the CPU 21 can be printed by pressing a print button 26. .

In the above description, it is assumed that the buzzer 27 is sounded when the information of the occurrence of the abnormality is notified. However, a voice message such as "An abnormality has occurred" is generated by using the voice synthesis technology. May be output.

As described above, according to this security system, the predetermined processing relating to the terminal device is performed in a decentralized manner in the terminal unit or the terminal control unit of the system of the terminal device. The processing load on each terminal control unit is light. The master control unit 20 performs processing of communication with the terminal control unit and the center device 9, processing of storing received information, processing of output, and the like. The center device 9 sets output and guards the common unit. Since processing for setting various items such as state setting, and processing for communication, information storage, and display are performed, the load of these processing is very light as compared with the conventional center device. . And
As a result of this distributed processing, each terminal unit 40, 60, 80, 100, each terminal control unit 30, 5,
