Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art A system generally called a center device system is installed at a location for centrally managing security information of a security company. As shown in FIG. 5, this center device system is composed of a security receiver 1, a data processor 2 such as a personal computer, and a communication line 12 connecting the security receiver 1 and the data processor 2.

Although not shown in FIG. 5, 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 at a security destination 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. 5, a plurality of office lines are connected to the security receiver 1. However, as shown in FIG. 6, 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, in the conventional center device system, the communication line 12 connecting the security receiver 1 and the data processor 2 is RS-23.
Since it was a serial communication line such as 2C, not only the data transmission rate was slow, but also it was possible to communicate only one-on-one, so the number of crime prevention reporting devices to be managed increased and 1
When the number of devices that can be managed by one security receiver 1 is exceeded, another set of center devices including the security receiver 1 and the data processing device 2 must be added as shown in FIG. .

[0011] However, if the center device is added by one set each time the number of the crime prevention notification devices is increased, not only the cost is increased but also space is required to install the center device. There was also a problem from the viewpoint of effective use of the company space. Further, the data processing device 2 manages time, and the operation of the entire center device system is managed by this time. For example, the data processing device 2 manages the data received from the crime prevention receiving device 1 by adding a time. For example, when data on occurrence of an abnormality is received from the security receiver 1, the time data is added to the data and displayed on a monitor or stored in a predetermined memory. As a result, for example, the supervisor of the monitor can clearly recognize what kind of abnormality occurred at what time and place.

However, since this time is managed by the microcomputer used as the data processing device 2, an error occurs depending on the precision of the clock of the microcomputer.

Therefore, in the past, when the supervisor of the center device system determines that the time is off, it is manually corrected. However, such work is not only troublesome, but time error is also caused. If the user does not notice, there is a problem that the data transmitted from the crime prevention reporting device has an incorrect time.

The present invention is intended to solve the above 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 center device system which can be dealt with only by adding the security receiver 1.

It is another object of the present invention to provide a center device system capable of automatically correcting the time for managing the operation of the entire center device system.

[0016]

In order to achieve the above-mentioned object, a center device system according to claim 1 is a security receiver for receiving data transmitted from a security reporting device via a telephone line, and a security receiver. In a center device system including a receiving device and a data processing device for exchanging data, the crime prevention receiving device and the data processing device are bus-connected.

The center device system according to claim 2 is the center device system according to claim 1, wherein
The security receiver receives the data transmitted from the security reporting device via a telephone line, and accesses the station line processing means for storing the received data and a plurality of station line processing means to sequentially access each station line processing means. Control means for fetching the stored data, and the control means calls the station line processing means which has not captured the station line at a predetermined time to make a call to the station line which is providing the time service, and then fetches the data. It corrects its own time based on the time signal,
The data at the corrected time is transferred to the data processing device.

[0018]

First, the center device system according to claim 1 is as follows. In this center device system, the crime prevention reception device and the data processing device are connected by a bus. Therefore, if the number of crime prevention notification devices increases, only the crime prevention reception device needs to be added and the bus connected, and the cost can be reduced compared to the conventional case where the center device system is added for each set. be able to.

The center device system according to claim 2 is as follows. In this center device system, the local line processing means of the security receiver is used to make a call to the local line that is providing the time service, and the own time is corrected based on the time signal received at that time.

Therefore, the time for managing the operation of the entire center device system is automatically corrected.
The operation can be performed at the correct time, and the burden on the observer can be reduced.

[0021]

Embodiments will be described below with reference to the drawings.
FIG. 1 is a diagram showing a configuration of an embodiment of a center device system according to the present invention, in which 30 is a data bus and 31 is an address bus. In the following, the data bus 30 and the address bus 31 are collectively referred to as an external bus.

In FIG. 1, the security receiver 1 and the data processor 2 are connected by an external bus. It goes without saying that the data processing device 2 is equipped with a bus interface for connecting to the external bus (hereinafter, the interface is referred to as I / F). Further, as will be described later, the control board 4 of the security receiver 1 is also provided with an external bus I / F 16 for connecting to an external bus.

As described above, the security receiver 1 can be easily connected to the external bus, and as a result, even if the number of security reporting devices to be managed increases, the security receiver 1 can be operated as shown in FIG. This can be dealt with only by adding the receiving device 1.

Next, the security receiver 1 will be described with reference to FIG. In FIG. 2, 10 is a data bus,
Reference numeral 11 indicates 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 station line board 4. Further, the control board 3 has a communication line 12
Is connected to the data processing device 2 (not shown in FIG. 2).

FIG. 3 is a diagram showing an example of the configuration of the central line board 4, which includes 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 processing relating to the exchange of data with the crime prevention reporting device it manages.

The modem 18 carries out a process of sending out data on the station line and a process of fetching data on the station line, and is 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 reason why the central line board 4 is constructed in this way is as follows. That is, the conventional office line board 3 only has the function as a modem as described above,
Since the control board 4 performed the process of receiving the data reported from the crime prevention notification device and the process of transmitting the data to the crime prevention notification device, the load on the control board 4 is very large, and therefore the number of the crime prevention notification devices increases. In this case, there is a problem that simply adding only the local line board 3 increases the load on the control board 4 and cannot cope with the situation.

Therefore, in the past, when the number of security notification devices to be managed has increased and the number of security devices exceeds the number that can be managed by one set of center device consisting of the security receiver 1 and the data processing device 2, FIG. Security receiver 1 as shown
There was no choice but to add another set of center equipment consisting of the data processing equipment 2.

Therefore, the station line board 4 is constructed as shown in FIG. 3 and is connected to the control board 3 by a bus. According to this configuration, the central office board 4 can be formed on one printed board, and can be connected to the control board 3 by a simple operation of connecting an internal bus. If two spare slots are provided in advance, it is assumed that one station line board can manage 100 crime prevention report devices, and if two station line boards are added to the slot, 200 crime report systems will be installed. Can be dealt with even if it increases.

Therefore, it is possible to manage 100 crime prevention reporting devices with another station line board 4, and if the crime prevention receiving device 1 is provided with two spare slots, in this center device system. If the number of security reporting devices is up to 200, you can deal with it by simply adding the central line board 4 to the security receiving device 1 and connecting the internal bus, and if the number of security reporting devices increases In this case, the security receiver 1 should be added and an external bus should be connected.

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

FIG. 4 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 bus 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 bus I / F 16 is the data bus 30 and the address bus, which are the external buses of the control board 3. Three
It is an interface for connecting to 1.

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 office board 4 itself has a 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.

The data transfer from the control board 3 to the data processing device 2 may be performed by instructing the data transfer from the data processing device 2 to the control board 3, or the control board 3 may perform a predetermined cycle. Alternatively, the data may be transferred to the data processing device 2 as needed.

In the former case, an address is assigned to the control board 3 of each security receiver 1, and the data processing apparatus 2 addresses the same as in the case where the control board 3 fetches data from the central line board 4. This can be done by sequentially and cyclically sending the address of each control board 3 to the bus 31.

In the latter case, the data processing device 2
The control board 3 that is going to transfer data to the device first issues a bus use request on the external bus, and transfers the data to the data processing device 2 if the external bus is not used.

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 receipt of this, the CPU 13 uses the internal bus to inquire of each station line board 4 whether or not it is currently capturing the station line, thereby searching for the station line board 4 not capturing the station line. 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 described above, since the security receiver 1 and the data processor 2 are connected to the bus, the data can be transferred at a higher speed than in the case where the conventional serial communication is used. Similarly, data transfer between the control board 3 and the central office board 4 can be performed at high speed.

Next, the operation of the time adjustment process will be described. When the currently used time reaches a predetermined time, the data processing device 2 gives the current time to the control board 3 of the security receiver 1 and instructs the time correction process.

When only one security receiver 1 is connected, it is sufficient to point to the control board 3 of the security receiver 1, but as shown in FIG. 1, a plurality of security receivers 1 are connected. In this case, a specific security receiver 1 may be specified, or each control using an external bus may be performed in the same manner as when the control board 3 searches for the local line board 4 that does not capture the local line. It suffices to search for the control board 3 that can perform the time adjustment processing by inquiring of the board 3 whether the time adjustment processing is possible. Here, for ease of understanding, it is assumed that the control board 3 that performs the time adjustment process is predetermined.

The time when the instruction is issued to the control board 3 is the time when the 880 Hz sound is emitted by the time signal service.
Just a minute ago. For example, when the time is corrected based on the time signal of 1:00 am, this instruction may be given to the control board 3 at 0:59 am. This is because it is usually unthinkable to cause an error of 1 minute per day in a normal microcomputer. Of course, two minutes ago is also possible.

When the CPU 13 of the control board 3 receives the instruction, it searches for a station line board 4 which is not currently capturing the station line in the same manner as described above, and the current time for the station line board 4 is searched. Is given, and the time adjustment process is instructed.

As a result, the CPU 17 of the local line board 4 concerned
Controls the modem 18 to dial the telephone number for which the time signal service is provided. When 880 Hz is detected, C
The PU 17 determines that the time to be corrected has arrived at that time and corrects the time. Therefore, for example, when correcting the time based on the time signal of 1:00 am, the time when 880 Hz is detected is 1:00 am.

When the time is corrected, the CPU 17 of the central line board 4
Starts timing based on the corrected time, and then notifies the control board 3 of the current time when the control board 3 requests data transfer.

On the other hand, the CPU 13 of the control board 3 starts time measurement based on the time received from the central line board 4, and thereafter when data is transferred from the data processing apparatus 2 or to the data processing apparatus 2. When the timing of data transfer comes, the current time is notified to the data processing device 2.
Of course, the CPU 13 of the control board 3 may immediately transfer the time data to the data processing device 2 when the time data is received from the central line board 4.

By performing the above operation, the time for operating the center device system is automatically corrected. It should be noted that this time adjustment process should be performed once a day.

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.
