BACKGROUND OF THE INVENTION
The present invention relates to security status setting device Ru using the security system.
[0002]
[Prior art]
One configuration example of the security system is shown in FIG. In FIG. 3, 1 is a security device, 2 is a security status setting device, and L is a network such as a LAN.
In the place where the security system is constructed, a security area, which is a unit for performing security, is defined. In each security area, a security status setting device 2 and at least one sensor are installed. Each security status setting device 2 and each sensor are connected to the security device 1 as shown in FIG. Yes. The security status setting device 2 sets the security status of the security area from the security status to the release status or vice versa. In FIG. 3, _{n 1 to} 2 _n security state setting devices are connected to the security device 1 via the network L, but may be connected to the security device 1 independently for each device. . Here, it is assumed that the security device 1 and each of the security status setting devices 2 ₁ to 2 _n perform communication by a predetermined method via the network L.
[0003]
Each warning area, each sensor, and each security status setting device 2 are assigned different addresses, and the sensor address indicating which address sensor is installed in which warning area and the warning area of the warning area. The correspondence between the address and the address of the security state setting device and the address of the security area such as which address the security state setting device is installed in which security area are registered in the security device 1 in advance. It is to be noted that the address of the security state setting device 2 and the sensor address are usually set by a dip switch or mounted by installing a ROM in which the address is written.
[0004]
The security device 1, a signal from each sensor, based on the alert state of the surveillance area notified from security state setting unit 2 ₁ to 2 _n, performs processing of predetermined security. There are various types of security processing, but a typical one is abnormality notification processing. That is, when a certain warning area is in a warning state, the security device 1 determines that an abnormality has occurred in the warning area when it receives a warning signal from a sensor associated with the address of the warning area. Then, data indicating that an abnormality has occurred in the center device installed in the security center of the security company is transmitted via the telephone line. This is the process of abnormality notification.
[0005]
By the way, various methods are conventionally known as a method for setting a security state by the security state setting device 2, but in recent years, a method using a card such as an IC card or an optical card has been increasingly adopted. ing. One configuration example of a security state setting device that sets a security state using such a card is shown in FIG. FIG. 4 shows a configuration example of a guard state setting device that can set the guard state from the guard state to the released state or vice versa by simply inserting the card into the card reader. Indicates a card reader, 7 indicates a memory, and 8 indicates a communication control unit. The communication control unit 8 is for communicating with the security device 1 via the network L. The memory 7 stores an ID number (hereinafter referred to as a permission ID number) that is permitted by the security state setting device 2.
[0006]
Now, when the card is inserted, the card reader 6 reads the ID number written on the card and passes the read ID number to the control device 5. When receiving the ID number from the card reader 6, the control device 5 searches the ID number stored in the memory 7 and determines whether the ID number received from the card reader 6 is stored in the memory 7. . When the ID number received from the card reader 6 is stored in the memory 7, the security state is reversed as the permission ID number, and the resulting security state is notified to the security device 1 by the communication control unit 8. To do. Accordingly, when the card is inserted into the card reader 6 in the alert state and the ID number is the permission ID number, the control device 5 sets the guard state from the alert state to the release state, and enters the release state. The security device 1 is notified of the setting. Further, when the card is inserted into the card reader 6 when in the release state and the ID number is the permission ID number, the control device 5 sets the security state from the release state to the warning state, and enters the warning state. The security device 1 is notified of the setting.
[0007]
However, if the ID number received from the card reader 6 is not stored in the memory 7, the control device 5 ignores the ID number as not being a permission ID number and maintains the previous security state.
[0008]
[Problems to be solved by the invention]
However, conventionally, as the memory 7 of the security state setting device 2, a non-volatile memory that retains the stored contents even when the power is turned off is used.
[0009]
As described above, a security area is defined at a location where a security system is constructed. However, for some reason, the security area may be divided and the number of security areas may increase. When the number of security areas increases in this way, a new security status setting device is newly added, but each of the security status setting devices to be added at that time has a permission ID in the nonvolatile memory. There is a problem that it is troublesome because it is necessary to write the number and mount it in the security state setting device. This problem becomes more prominent as the number of additional security state setting devices increases.
[0010]
Also, for example, in the case of a tenant building, there are cases where a tenant moves out or enters a new occupancy. It is normal to delete the existing ID number, give a new tenant a new ID number, and write the ID number as a permitted ID number in the memory 7 of the security status setting device 2 corresponding to the tenant. . As described above, it may be necessary to delete the permission ID number from the memory 7 or write a new permission ID number into the memory 7. It was.
[0011]
Accordingly, the present invention is an object to provide an automatic can be Ru security status setting device to perform the registration of the ID numbers to the memory of the security status setting device.
[0012]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the security state setting device according to the present invention has a sensor connected to a security state setting device that sets the security state of a warning area from a warning state to a release state, or from a release state to a warning state. And a security system that communicates with the security status setting device via the network and that performs a predetermined security process based on a signal from the sensor and a security status notified from the security status setting device. The security status setting device used for the security status setting device has an address, the control device and the security status of the corresponding security area in the security status setting device from the warning status to the release status, or from the release status and a volatile memory for writing the ID number used to set the alert state as the authorization ID number, the control device, the power is turned on If the security device is assigned a self-address and requests the download of a permission ID number, and the permission ID number is downloaded from the security device, a process of writing it into the volatile memory is performed. It is characterized by.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the invention will be described with reference to the drawings.
Figure 1 is a diagram showing an embodiment of a security system using the engagement Ru security status setting device of the present invention, in the figure 9 is a memory, 10 is a control device, 11 is a communication control unit, 12 operation unit, Reference numeral 13 denotes a permission ID number database (hereinafter simply referred to as DB), and 14 denotes a line control unit. In FIG. 1, the same components as those in FIGS. 3 and 4 are denoted by the same reference numerals. Here again, it is assumed that the security device 1 and each of the security status setting devices 2 ₁ to 2 _n communicate via the network L. The security state setting method in the security state setting device 2 is a method in which the security state can be set from the warning state to the released state or vice versa by simply inserting the card into the card reader.
[0014]
First, the security device 1 will be outlined.
The security device 1 includes a control device 10, a communication control unit 11, an operation unit 12, a DB 13, and a line control unit 14. As described above, a signal from the sensor is input to the security device 1, but the illustration is omitted in FIG.
[0015]
The control device 10 manages the operation of the security device 1 in an integrated manner, executes predetermined security processing, and performs the operations described later.
The communication control unit 11 is for communicating with the guard state setting device 2 via the network L.
The operation unit 12 is used for switching the operation mode of the control device 10, setting registration of the permission ID number table, and the like, and includes numeric keys and symbol keys such as “*” and “#”.
[0016]
The DB 13 defines what ID number is permitted in each guard state setting device 2 and the permission ID number that defines the correspondence between the address of the guard state setting device 2 and the permission ID number in the guard state setting device 2 The table is registered.
The structure of the permission ID number table registered in the DB 13 can be determined as appropriate. For example, the structure shown in FIGS. 2A and 2B can be used.
FIG. 2A shows a structure in which the addresses and ID numbers of the security state setting device 2 are arranged in a matrix, and each security state setting device 2 only accepts a circled ID number. It is made to be done. That is, in FIG. 2A, the security state setting device with the address 1 has the ID number “1111” as the permission ID number, and the security state setting device with the address 2 has the ID number “2222” as the permission ID number. It becomes. The same applies to other cases.
FIG. 2B shows a structure in which a permission ID number is registered for each address of the security state setting device.
[0017]
The line control unit 14 is for reporting to the center device of the security company via a telephone line. If the telephone line is an analog line, it is composed of a modem, and if it is a digital line, a terminal adapter and a DSU ( Digital service unit).
[0018]
Now, the control device 10 of the security device 1 is provided with two modes as operation modes: a setting mode and a security mode. The security mode is a mode in which a predetermined security process is performed. In the security mode, the control device 10 performs, for example, the above-described abnormality notification process. The setting mode is a mode for setting and registering the permission ID number table in the DB 13.
[0019]
The operation unit 12 is used to switch between the setting mode and the security mode, and to change the permission ID number table of the DB 13 and register a new permission ID number table in the setting mode. When the operation mode is switched from the setting mode to the security mode by the operation unit 12, the permission ID number table registered in the DB 13 is downloaded to the security status setting device 2. When downloading, the permission ID number table may be downloaded as it is. For example, even if the structure of the permission ID number table is as shown in FIG. 2A or as shown in FIG. Since the address assigned to the setting device is recognized, it is possible to recognize the permission ID number corresponding to the own security state setting device by referring to the permission ID number table. However, it is a matter of course that only the permission ID number registered corresponding to each security status setting device 2 may be downloaded. Here, it is assumed that the permission ID number table itself registered in the DB 13 is downloaded.
[0020]
In addition, when there is a download request for the permission ID number table from the security state setting device 2, the control device 10 of the security device 1 reads the permission ID number table from the DB 13 and makes the download request. 2, the permission ID number table is downloaded.
[0021]
Next, the security state setting device 2 will be outlined. Each guard state setting device 2 is assigned a unique address, as in the prior art.
[0022]
The memory 9 of the guard state setting device 2 stores a permission ID number, but is different from the conventional one, and is composed of a volatile memory that can be written and read at any time. Volatile memory is a type of memory whose stored contents are erased when the power is turned off.
[0023]
The power of the security state setting device 2 is supplied from a power supply device (not shown) or supplied from the security device 1 via a network L line. It is well known to superimpose a power supply voltage and a signal on a communication line.
[0024]
Further, the control device 5 executes a predetermined startup process when the power is turned on, and requests the security device 1 to download the permission ID number table when the startup process is completed. That is, at this time, the control device 5 creates a transmission data by attaching its own address to a command requesting download and passes it to the communication control unit 8. As a result, the communication control unit 8 transmits the transmission data to the security device 1.
[0025]
Furthermore, when the permission ID number table is downloaded from the security device 1, the communication control unit 8 of the security state setting device 2 receives it and passes it to the control device 5. When receiving the permission ID number table from the communication control unit 8, the control device 5 performs a process of writing it into the memory 9.
[0026]
As described above, the following operation is performed in this security system.
[0027]
When adding or deleting the address of the security status setting device accompanying the increase or decrease of the security area, or when adding or deleting the permission ID number in each security status setting device, the operator operates the operation unit 12 of the security device 1. Then, the operation mode of the control device 10 is changed from the security mode to the setting mode, and a new permission ID number table is set and registered. As a result, the control device 10 writes and registers the newly set permission ID number table in the DB 13.
[0028]
When registration of the new permission ID number table is completed in this way, the operator returns the operation mode from the setting mode to the security mode by the operation unit 12, but when the operation mode is returned to the security mode, the control device 10 The permission ID number table is read from the DB 13 and transmitted to all the security state setting devices 2. And the control apparatus 5 of each guard state setting apparatus 2 will write the received permission ID number table in the memory 9, if this is received. Thereby, the permission ID number table is downloaded.
[0029]
Further, the security status setting device 2 may be maintained due to a failure or the like. During such maintenance, the security status setting device 2 is normally disconnected from the network L and the power is normally turned off. At this time, the contents of the memory 9 are erased. Thereafter, when the maintenance is completed, the control device 5 is connected to the network L again and turned on. However, the control device 5 performs a start-up process when the power is turned on. In this start-up process, the dip switch The address assigned to itself is recognized by reading the state of data and the ROM data. After the start-up process is completed, the security device 1 is requested to download the permission ID number table as described above. When receiving the download request, the control device 10 of the security device 1 reads the permission ID number table from the DB 13 and transmits the data of the permission ID number table to the address of the security state setting device 2 that has made the download request. . And the control apparatus 5 of the said security state setting apparatus 2 will write this received permission ID number table in the memory 9, if the permission ID number table transmitted from the security apparatus 1 is received. Thereby, the permission ID number table is downloaded.
This operation is the same when a new security state setting device is connected to the network L.
[0030]
As described above, when a security system is constructed using the security device 1 and the security status setting device 2, the permission ID number is automatically written in the memory 9 of each security status setting device 2. It is possible to eliminate the hassle of having to perform manual operations such as.
In addition, since it is only necessary to change the data in the DB 13 of the security device 1 to change the deletion or addition of the permission ID number, it is possible to significantly reduce troublesomeness or troublesomeness.
Further, the memory 9 of the security state setting device 2 is a volatile memory, and the stored contents are erased when the power is turned off, which is effective in ensuring safety.
[0031]
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various deformation | transformation is possible. For example, in the above embodiment, the security state setting device 2 uses a card, but an ID number is input with a numeric keypad, and the input ID number is compared with the permission ID number registered in the memory 9. Then, when they match, the security state may be switched from the warning state to the released state or vice versa. In short, the guard state setting device of the present invention can be generally applied to a guard state setting device having a memory for registering a permission ID number.
