Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a security system for housing complexes such as condominiums.

(Background technology) Conventional mechanical security systems for general homes install terminal devices such as sensors inside the home, and when a change in status occurs, the sensors sense the sensor information, which is sent to a security center using a telephone line. It was a system that would notify the public. Furthermore, mechanical security systems in buildings and factories are systems that report sensor information to a security center using a dedicated line.

In the case of mechanical security systems that use telephone lines, when there is a power outage, information about the power outage cannot be reported to the security center. Also,
In order to report power outage information, each terminal device required a backup battery. Furthermore, if the terminal or center is busy, the user must wait until the call ends. Furthermore, if the telephone line is disconnected, there are drawbacks such as the inability to report seisa information to the security center.

However, since telephone line usage charges are paid as part of the basic telephone charges, maintenance costs are low and there are advantages in that additional service functions for users (e.g. auto-dial, answering machine) are available. be. Therefore, mechanical security systems using telephone lines are often used for general residences.

In addition, in the case of a mechanical security system that uses a dedicated line, maintenance costs are high because you have to pay for the use of the dedicated line, and the purpose of using the dedicated line is limited to mechanical security, and the user can use it for other purposes. Although it has the disadvantage that it is difficult to receive services, it is constantly sending information, so
It has the advantage that even if there is a power outage or line disconnection, it can be detected without the center receiving a signal, so it is often used as a mechanical security system for buildings, factories, etc.

Therefore, since conventional mechanical security systems have advantages and disadvantages, a low cost and highly reliable mechanical security system is being sought.

(Problem to be solved by the invention) The problem to be solved by the present invention is to solve the problems of the prior art.
In addition to multiple security terminal devices (hereinafter referred to as terminal devices) connected to the security center via conventional telephone lines, security terminal devices (hereinafter referred to as monitoring devices) connected to the same center via a dedicated line are also connected to the security center as terminals. The newly installed device is improved so that each terminal device can be monitored and controlled from the security center via the monitoring device by connecting with each of the terminal devices, and the cost is low and service functions for users can be added. The purpose of the present invention is to provide a highly reliable mechanical security system for apartment complexes.

(Structure and operation of the invention) Embodiments of the present invention will be described with reference to the accompanying drawings.

The accompanying drawings illustrate an embodiment of a collective security system according to the present invention. 1 is a sensor that detects the security state; 2 is a terminal device that transmits and receives information from the sensor 1; 3 is a telephone line; 4 is a data way that connects each terminal device; 5 is a monitoring device that monitors and controls the terminal device 2; 6 is a dedicated line, 7 is an exchange, and 8 is a security center.

A sensor 1 and a terminal device 2 are connected and installed in each house. Each terminal device 2 is connected by a dataway 4, and is also connected to a monitoring device 5.

When a sensor 1 in the house detects an abnormality, a terminal device 2 automatically issues a notification via a telephone line 3. That is, the terminal device 2 sends out the telephone number of the security center 8, and when the terminal device 2 and the security center 8 are connected by the exchange 7, information inside the house is reported by code. During the talk at Security Center 8,
Or, if connection to the security center 8 is not possible due to disconnection of the telephone line 3, data is sent to the monitoring device 5 via the data way 4, and information inside the house is reported via code to the security center 8 via the dedicated line 6. . Further, the monitoring device 5 constantly checks the operation of each terminal device 2 through the dataway 4, and if there is a power outage or failure of the terminal device 2, the dedicated line 6
The situation of the failure is reported to Security Center 8 through. Further, information on the terminal device 2 other than sensor information (for example, telephone number, etc.) can be collected and written through the data way 5.

Therefore, according to the present invention, there are the following advantages.

(1) In the event of a power outage, equipment failure in each terminal device 2 can be reported to the security center through the monitoring device 5, so the cost of the terminal device 2 can be reduced by eliminating the need for a notebook on each terminal device 2.

(2) When the telephone line 3 is out of service, or when it is not possible to report to the security center 8 because the terminal or the center is busy, etc., the security center 8 can be notified in a short time via the monitoring device 5, which increases the reliability of security. .

(3) Since the fee for using the dedicated line 6 can be divided by the number of terminal subscribers, the fee borne by each subscriber is relatively low.

(4) Since the telephone line 3 is not monopolized for a long time, the subscriber's telephone charges are reduced and the telephone can be used effectively.

(5) In addition, various additional functions can be improved through the data way 4. Examples thereof will be described below.

(b) Terminal equipment can be inspected at the security center using the following methods. In order to check the terminal device 2, the security center 8 issues a test alarm command to the monitoring device 5 through the dedicated line 6, and the monitoring device 5 sends the test alarm to each terminal device 2 through the data way 4. The device 2 is
Test notification will be sent to the center.

(b) Time can be set from the security center 8 to the terminal device 20 clock.

When security center ()-1/-8 moves or changes its route, the center telephone number stored in the terminal device can be automatically replaced.

(d) Monitoring device 5 for auto-dial phone number for users
Since the telephone number display function of each terminal device 2 can be removed by printing the information and confirming it with each user, the cost of the terminal device 2 can be reduced.

In the above embodiments of the present invention, a mechanical security system for a residential complex has been described, but it is clear that the present invention can also be used for other collective terminals.

(Effects of the Invention) As explained above, the present invention connects a plurality of telephone line terminal devices to a dedicated line monitoring device through a dataway, and has two connection routes to a security center. The security system can reliably issue alarms in a short period of time, which has the advantage of reducing telephone charges and making effective use of telephones.In addition, there is no need for telephone lines to be used at each terminal during a power outage. Even if the system is disconnected, it can be reported as a failure, and there is also the advantage that each terminal device can be maintained and inspected from the center, and the telephone number to which notifications are sent can be changed, etc., making it possible to configure a highly reliable mechanical security system at a low overall cost. Therefore, it can be used for mechanical security of housing complexes such as condominiums.
