Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a security receiver provided in a security company or the like.

[0002]

2. Description of the Related Art A device generally called a center device is installed at a location for centrally managing security information of a security company. As shown in FIG. 4, this center device is composed of a crime prevention receiver 1 and a data processor 2 such as a personal computer.

Although not shown in FIG. 4, a security alarm device having terminal devices such as a security sensor such as a heat ray sensor, a fire sensor, a gas leak sensor, etc. is installed in a security place such as a general home or an office building. Therefore, when there is an intruder or a fire occurs, the crime prevention notification device at the location notifies the center device of the occurrence of an abnormality. In addition, not only when an abnormality occurs in the crime prevention reporting device,
There is also known one provided with a function of periodical notification that periodically notifies the center device at predetermined time intervals.

In FIG. 4, the security receiver 1 is connected to a plurality of office lines. As shown in FIG. 5, the security receiver 1 includes a plurality of office line boards 3 and a control board 4. In addition, each station line is connected to a different station line substrate 3. One telephone number is assigned to one station line, and each station line is notified of a predetermined number of security reporting devices, for example, 100 security reporting devices. . That is, one local line board 3
Can be said to manage, for example, 100 security reporting devices. It should be noted that each crime prevention reporting device is provided with an ID number.

Next, the operations of the central line board 3 and the control board 4 will be described. The central office line board 3 is a modem, and when there is a notification from the crime prevention notification device, processing for acquiring the local line is performed to notify the control board 4 that the crime prevention notification device has received a notification, and control When an instruction is given from the substrate 4, the telephone number of the instructed crime prevention notification device is dialed.

When the control board 4 is notified by the station line board 3 that the station line has been captured, the control board 4 receives the data from the crime prevention reporting device, reports it, and stores it in a predetermined memory. I do.

Further, the control board 4 reads out the data stored in the memory and transfers it to the data processing device 2 periodically or when the data processing device 2 is instructed to transfer the data. Further, when the control board 4 is instructed by the data processing device 2 to transmit data to a crime prevention notification device, the control circuit board 4 calls the station line substrate 3 that manages the crime prevention notification device, and calls the telephone number of the crime prevention notification device. Is dialed, and when the office line is connected, a process of transmitting data to the crime prevention notification device is performed.

As a result of the above operations, the monitor of the data processing device 2 shows in what state each crime prevention notification device is currently, or when any abnormality occurs, which crime prevention notification device reports an abnormality. Information such as whether or not has been performed will be displayed.

Further, various data will be transmitted from the data processing device 2 to the crime prevention reporting device.

[0010]

However, the conventional central office board 3 only has the function as a modem as described above, and the processing for receiving the data notified from the crime prevention notification device and the crime prevention notification are performed. Since the control board 4 was performing the process of transmitting data to the device, when the load on the control board 4 is very large and therefore the number of the crime prevention notification devices increases,
There is a problem that simply adding only the local line board 3 increases the load of the control board 4 and cannot cope with it.

Therefore, when the number of crime prevention notification devices to be managed increases in the past and the number can be managed by one set of the center device including the crime prevention reception device 1 and the data processing device 2, FIG. As shown, another set of center equipment including the crime prevention receiver 1 and the data processor 2 was added.

[0012] However, adding a set of center devices each time the number of crime prevention reporting devices increases in this way not only leads to an increase in cost, but also space is required to install the center devices, so security is required. There was also a problem from the viewpoint of effective use of the company space.

The present invention is to solve the above-mentioned problems, and when the number of crime prevention reporting devices to be managed increases,
It is an object of the present invention to provide a crime-prevention receiving device which can be dealt with only by adding a central office line board.

[0014]

In order to achieve the above-mentioned object, a security receiver of the present invention is a station which receives data transmitted from a security reporting device via a telephone line and stores the received data. In a security receiver comprising line processing means and control means for sequentially accessing a plurality of station line processing means to fetch data stored in each station line processing means, the station line processing means is connected to the control means by a bus. It is characterized by

[0015]

Since the station line processing means not only functions as a modem but also directly transmits and receives data to and from the crime prevention reporting device, the burden on the control means is greatly reduced as compared with the prior art.

Further, since the station line processing means and the control means are connected to the bus, if the number of crime prevention reporting devices increases, the station line processing means may be added and the control means may be connected to the bus.
The cost can be significantly reduced as compared with the conventional case where the center device is added for each set.

Further, since the station line processing means can be constructed as one board, if the slot for adding the station line processing means to the security receiver is prepared in advance, the station line processing means can be added. It is very easy to do and does not have any space problems.

Embodiments will be described below with reference to the drawings.
FIG. 1 is a diagram showing the configuration of an embodiment of a security receiver according to the present invention, in which 10 is a data bus and 11 is an address bus. In the following, the data bus 10 and the address bus 11 are generically called an internal bus.

The security receiver 1 comprises a control board 3 and a plurality of office line boards 4. The control board 3 and each office line board 4 are connected by an internal bus consisting of a data bus 10 and an address bus 11. There is. It is obvious to those skilled in the art that the connection between the control board 3 and the internal bus and the connection between the central office board 4 and the internal bus can be easily made by using connectors.

An address is set for each of the central office wiring boards 4. Further, the control board 3 has a communication line 12
Is connected to the data processing device 2 (not shown in FIG. 1).

FIG. 2 is a diagram showing an example of the configuration of the central line board 4, which comprises a CPU 17, a modem 18, a memory 19, and an internal bus interface 20. In the following, the interface will be referred to as I / F.

When there is a notification from the crime prevention notification device, the CPU 17 receives data transmitted from the crime prevention notification device, interprets the data, and receives data such as converting the received data into a predetermined format. In addition to performing the above, the operation of the central line board 3 is centrally managed.

Further, when transmitting data to the crime prevention notification device, the modem 18 is activated to dial the telephone number of the crime prevention notification device to which the data should be transmitted, and the security communication device captures the local line. And processing for transmitting data to be transmitted.

That is, the CPU 17 carries out all the processes relating to the exchange of data with the crime prevention reporting device it manages.

The modem 18 performs a process of sending out data on the station line and a process of fetching data on the station line, and has been conventionally used. The memory 19 is for storing the data received from the crime prevention reporting device and converted into a predetermined format. Internal bus I / F 20
Is an interface for connecting the station line substrate 4 to the data bus 10 and the address bus 11.

The configuration of the central office board 4 has been described above. Next, the configuration of the control board 3 will be described.

FIG. 3 is a diagram showing an example of the configuration of the control board 4, which includes a CPU 13, a memory 14, an internal bus I / F 15, and an external I / F 16.

The CPU 13 sequentially cyclically accesses each station line board 4, fetches the data stored in the memory 19 of each station line board 4, and temporarily stores it in the memory 14.
The data stored in the memory 14 is transferred to the data processing device 2. Therefore, as compared with the conventional control board, it is not necessary to perform processing relating to communication with the crime prevention notification device as in the conventional case, and therefore the load on the CPU 13 is very light.

The internal bus I / F 15 is an interface for connecting the control board 3 to the data bus 10 and the address bus 11, and the external I / F 16 is a communication line 12 for communicating with the data processing device 2. It is an interface for connecting.

Next, the operation of the control board 3 and the local line board 4 will be described. First, the reception processing of the central line board 4 is as follows. When a call is made from the crime prevention notification device, the modem 18 captures the local line and notifies the CPU 17 of the call. Upon receiving this, the CPU 17 receives the transmitted data, determines which security reporting device the data is from, and what the content is, and writes the information in the memory 19 in a predetermined format.

The CPU 17 of the central line board 4 has its own memory 19
The data stored in 1 is not transferred to the control board 3, and when the data transfer is requested by the control board 3, the data written in the memory 19 is read and transferred to the control board 3.

The operation in that case is as follows. The CPU 13 of the control board 3 sequentially and cyclically sends out the address of the office line board 4 to the address bus 11 when taking in the stored data from the office line board 4. At this time, the CPU 17 of each station line board 4 determines whether the address transmitted to the address bus 11 is an address assigned to itself, and if it is not an address assigned to itself, ignores it, but assigns it to itself. If it is an address, the data stored in the memory 19 is transferred to the data bus 10.
Send to the top. Then, the control board 13 uses the internal bus I / F.
The data transferred from the central line board 4 via 11 is fetched and stored in the memory 14.

By the above operation, the CPU of the control board 3
Reference numeral 13 captures data from each station line board 4 in a predetermined cycle.

Data transfer from the control board 3 to the data processing device 2 can be set arbitrarily. For example, the data processing device 2 may instruct the CPU 13 of the control board 3 to transfer the data stored in the memory 14, and the CPU 13 of the control board 3 processes the data at a predetermined cycle. It is also possible to transfer to the device 2. However, since this is not an essential matter in the present invention, detailed description will be omitted.

The data processing device 2 may need to send data to the crime prevention reporting device. In that case, the data processing device 2 notifies the CPU 13 of the control board 3 of the data to be transmitted and the telephone number of the crime prevention notification device of the other party.

Upon receiving this, the CPU 13 searches for the station line substrate 4 which has not captured the station line by inquiring to each station line substrate 4 using the internal bus whether or not the station line is currently captured. Then, the CPU 17 of the local line board 4
The data to be transmitted to the destination and the telephone number of the other party's crime prevention reporting device. As a result, C of the local line board 4 concerned
The PU 17 causes the modem 18 to dial the notified telephone number and transmits the data.

When there are a plurality of office line boards 4 that have not captured the office line, the office line board 4 having the smallest address may be selected.

As is clear from the above description, the central line board 4 can be constructed by one printed circuit board, and can be connected to the control board 3 by a simple operation of connecting the internal bus. For example, if the security receiver 1 is provided with two spare slots in advance and one station line board can manage 100 security reporters, two slots will be installed in the station line board. If you add
It is possible to handle cases where the number of crime prevention reporting devices has increased to 200.

Although the embodiments of the present invention have been described above, it is apparent that the present invention is not limited to the above embodiments and various modifications can be made.
