[0002]

2. Description of the Related Art A so-called security system monitors anomalies such as intrusion of a pirate or the occurrence of a fire at a security target site such as a house or a facility. A security terminal device that senses and notifies the security center based on the sensing is installed at the site. The security center is connected to such security terminal devices installed in various places by a telephone line, thereby monitoring a large number of security target sites collectively. The telephone line used includes a general line, a dedicated line, an ISDN line, and the like.

Such a security system is monitored 24 hours a day, 7 days a week, based on a contract with a customer. However, as an actual operation, the security terminal device installed at the site to be managed is operated to perform the security start operation and the subsequent release operation, and only during the time interval between this start and release Is guarding. That is, a typical form of security is to specifically guard only during the night when people are unmanned, and not during the daytime when people are present.Therefore, the last exit from the security target site uses the security terminal device. By performing the security start operation, the monitoring at the center notified of the start is started, and the first attendant in the next morning performs the security cancellation operation, and the monitoring at the security center notified of the cancellation is ended.

[0004] The security is mainly performed to detect anomalies such as intrusion of a thief or the occurrence of a fire, and this is performed during a time period from a start operation to a release operation performed on the security terminal device. In addition, fire monitoring may be monitored for 24 hours separately from monitoring for intrusion of pirates.

When security is started, a connection confirmation signal is sent from the security terminal device at regular intervals (for example, at intervals of 30 minutes) to confirm that there is no abnormality in the telephone line with the security center.
The following preparations are made so that a notification immediately when an abnormality is found can be made at any time without any trouble. That is, in rare cases, a pirate disconnects the telephone line when intruding to prevent the security center from being notified. In order to know such a situation, a regular connection check (line is effective) Confirmation). Or,
The telephone line may be disconnected due to a typhoon or other accident, or the telephone line may not be connected due to an accident at the telephone company. It is.

[0006]

However, even if the security center recognizes that the telephone line has been interrupted, whether the telephone line has been disconnected by a pirate, the line has been disconnected by a typhoon, or the telephone company has failed. Cannot be diagnosed, and the necessity of emergency response cannot be determined.

In view of the above problems, it is an object of the present invention to provide a monitoring information converter and a monitoring information converter capable of monitoring a security target site without being affected by disconnection of a telephone line by wire. A security terminal device and a security system are provided.

Means for Solving the Problems and Effects of the Invention In order to solve the problem of abnormalities, the present application uses a portable telephone. That is, according to the first aspect of the present invention, abnormalities such as intrusion of a pirate or the occurrence of a fire at a security target site such as a house or a facility are monitored. We propose a converter to be used for a security terminal device that notifies a security center based on the information. This security terminal device has a terminal main unit having a sensor for detecting an abnormality, and a first terminal output from the terminal main unit, which is exemplified by a start operation or a release operation of monitoring or that there is an abnormality. And a terminal-side mobile phone that transmits the transmission information to a predetermined partner telephone. It is characterized in that it is converted into information. Due to the existence of this converter, it is possible to make a notification from the security terminal device from a mobile phone, and if it is a conventional wired telephone line, a failure due to disconnection was inevitable,
On the other hand, since a converter for transmitting information from a security device on site using a mobile phone is provided, it is possible to secure a notification path by the mobile phone.

According to the second aspect of the present invention, the terminal-side portable telephone has an input / output interface for a dialing signal from outside the machine, and a destination of a call to be dialed based on the dialing signal is set in advance. About the case. That is, the converter outputs a dial ring signal to the terminal side mobile phone when the first transmission information is output from the terminal main unit, and outputs the second transmission information after confirming the telephone connection. And The dialing signal output from the converter may be generated by the converter, or the signal generated by the terminal main unit may be input to the converter and output again. Many mobile phones are provided with a so-called "hands-free" switch-equipped microphone. When inserted into an input / output interface provided in the mobile phone, a reception / transmission operation by a switch operation and subsequent operations are performed. Something that can be used for conversations is already provided. By utilizing such existing functions of the mobile phone, it is possible to perform a telephone connection to a predetermined partner phone and a subsequent notification even if the user is unattended.

[0010] The invention according to claim 3 is characterized in that the first transmission information is converted into the second transmission information comprising an audio signal. Telephones are being used for more than speech, so those that can handle signals other than audio signals are being provided.However, the types of signals other than audio signals vary depending on the equipment provided. Depending on the mobile phone used, the interface with the security terminal device may match or mismatch. In this regard, voice transmission is a common information medium regardless of the type of telephone, and therefore, by using a voice signal, there is no need to select a telephone to be used, so that convenience and flexibility are excellent.

[0011] In the invention according to claim 4, the second transmission information is characterized in that the signal type is determined for each audio frequency of the audio signal. For example, a voice of 1000 Hz indicates that the operation has started, and a voice of 2000 Hz indicates that the operation has been released. A voice signal having a frequency corresponding to the first transmission signal is defined as a second transmission signal. It outputs. This facilitates analysis / recognition of the notification content on the receiving side, that is, post-processing after reception is facilitated.

According to a fifth aspect of the present invention, there is provided a security terminal device installed at a security target site such as a house or a facility.
The present invention is characterized by using the converter according to any one of (1) to (4), and eliminates a problem caused by disconnection of a conventional telephone line by wire. It is to be noted that the conventional wired telephone line can be freely combined with the mobile telephone line, thereby making the line redundant and improving the safety. The other party telephone provided at the security center may be a telephone connected by a conventional wired telephone line, or the other party telephone at the security center may be a mobile phone.

[0016]

Next, an embodiment of the present invention will be described. FIG. 1 shows claim 8 in which claims 6 and 7 are cited.
A security system 100 according to the ninth aspect, comprising a large number of security terminal devices 10, 10,... And a security center 20 for monitoring these collectively.

Each security terminal device 10 is installed at a security target site such as a house or a facility. The security terminal device 10 monitors anomalies such as intrusion of a thief or the occurrence of a fire at the security target site and generates the above-mentioned abnormality. Is detected, and a notification based on the detection is made. Then, the security center 20 receives the notification and uses the security center 20 to take a predetermined security action.

The security terminal device 10 and the security center 2
0 indicates that a connection can be established between the wired telephone line 1 and the wireless telephone line 2 using a mobile phone, and a notification from the security terminal device 10 is transmitted to the wired and wireless telephone lines 1 and 2. Has a double notification path.

The security terminal device 10 has a terminal main unit 11 having a sensor for detecting an abnormality, and the converter 12 according to any one of claims 1 to 4, which converts transmission information from the terminal main unit 11.
A terminal-side mobile phone 13 for transmitting the information converted by the converter 12 is provided.

The terminal main unit 11 has an operation unit 15 in addition to a sensor 14 for detecting an abnormality. The terminal main unit 11 can perform, for example, a start operation for starting monitoring at a site and an operation for releasing the operation. It has become. In addition, terminal main unit 11
The security center 20 is provided with a wired telephone line 1 and a wireless telephone line 2 using a mobile phone. Notifications from the terminal main unit 11 about operation contents and abnormalities are sent to these telephone lines 1 and 2. 2 via a dual path.

The converter 12 converts the first transmission information from the terminal main unit 11 into the second transmission information that can be input to the terminal-side mobile phone 13. The first transmission information includes start information and release information by the operating device 15, intrusion information and fire information by the detector 14, and other information such as the terminal number of the security terminal device 10. Note that these pieces of information are notified from the terminal-side mobile phone 13 and also from the wired telephone line 1, but a description thereof will be omitted.

The terminal-side mobile phone 13 has an input / output interface for a dialing signal from outside the machine,
The other party to be dialed based on the dialing signal is preset so as to be stored in a memory in the terminal-side mobile phone 13. When the first transmission information is output from the terminal main unit 11, a dial ring signal for the terminal-side mobile phone 13 is output in response to the first transmission information, and the first transmission information is input to the terminal-side mobile phone 13. After confirming that the telephone is connected, the second transmission information converted into a possible information form is output to the terminal-side mobile telephone 13. The first transmission signal is converted into second transmission information comprising an audio signal.
Hz, 2000 Hz for release information, 3000 Hz for intrusion information, and 4000 Hz for fire information, which are converted into signal sounds for each sound frequency. These sound signals are transmitted through the terminal-side mobile phone 13 to the security center. 20 is notified.

The security center 20 has a center main unit 21 for receiving a notification and a display 22 for displaying the contents of the notification from the center main unit 21.
Is received in parallel with the mobile phone. Therefore, in the security center 20, the security terminal device 1
The mobile phone 23 has a center-side mobile phone 23 as a partner telephone to be dialed, and further has an extracting means 24 for extracting information received by the mobile phone 23. The take-out means 24 has a function of inputting information from the mobile phone 23 and converting the information into the information form of the center main unit 21. As a result, the center main unit 21 obtains information from the extracting means 24 and also obtains information from the wired telephone line 1 and displays them on the display 22.

The information obtained from the portable telephone 23 and the information obtained from the wired telephone line 1 should have the same contents, and are displayed after performing a match check.

The method of using the above security system is as follows. First, at the security target site, at the end of the day, the last leaver operates the operating device 15 to start monitoring. Based on this operation, start information is output from the terminal main unit 11 and a notification via the wired telephone line 1 is sent to the security center 20.
And the notification by the mobile phone 13 is also made in parallel.

First, when the start information as the first information is output from the terminal main unit 11, the converter
Outputs a dialing signal to the terminal-side mobile phone 13. In the dialing by the terminal-side mobile phone 13, a telephone connection is made to the center-side mobile phone 23, which is the other party's phone, and if the connection is confirmed, an audio signal with a continuous sound of 1000 Hz is output. Send.

In the security center 20, the start information is received by the portable telephone 23 in parallel with the wired telephone line 1. When a call is made to the center-side mobile phone 23, the transmitted voice signal is received as reception information. The received signal is extracted by the extracting means 24, and is recognized as a 1000 Hz audio signal, and information indicating that monitoring of the security target site has started is output in the form of information of the center main unit 21. The center main unit 21 checks this received information against the separately received information from the wired telephone line 1 and displays it on the display 22 if they match. If they do not match, the cause is investigated as much as possible. For example, if the interruption is due to disconnection of the wired telephone line 1, the cause is further investigated,
It takes necessary measures.

When the monitoring is started in this way, the monitoring of abnormalities caused by intrusion and fire is continued until the monitoring is canceled. If an intrusion of a pirate is detected, an audio signal of 2000 Hz is transmitted if an abnormality due to a fire is detected, and a 3000 Hz audio signal is transmitted in the same manner as the start information, and the security center 20 receives and displays the audio signal, thereby taking necessary measures. it can. In the meantime, even if the telephone line 1 is cut off by a thief at the security target site, a notification path by the mobile phone 13 is secured, whereby security monitoring can be maintained.

Lastly, when the first employee on the next day comes to the office, the operator operates the operating device 15 to perform the operation of canceling the monitoring, thereby following the same processing as described above and receiving a notice of the cancellation. Thus, the monitoring of the security target site ends. Then, after the end of the day, the last leaver performs an operation start operation to start new monitoring, and the following,
We repeat the same.

The present invention is not limited to the above embodiment. The notification path may be a mobile phone only and a wired telephone line may not be used in parallel. Further, only the security terminal device has the mobile phone, and the security center may receive the mobile phone by a wired telephone. As a result, it is possible to avoid the damage caused by the cutoff of the telephone line (cutting the section A between the site and the telephone company X) by the bandit at the site. However, if the security center receives a signal by a wired telephone, it is not possible to avoid notification failure due to disconnection of the section B between the telephone company X and the security center 20 (for example, disconnection due to a typhoon). It is desirable to use a mobile phone at both the site and the security center. In addition, at the security center, when the information is received by the mobile phone, the content of the notification may be displayed on the display of the received mobile phone, instead of displaying it collectively on another display. Alternatively, a person may listen to an audio signal from a mobile phone, and the content of the notification may be understood as it is. Further, the notification route by the mobile phone (the route from the terminal-side mobile phone to the center-side mobile phone or the route from the terminal-side mobile phone to the center-side wired phone) may be doubled.
