Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to remote security by means of a mobile phone (including PHS) that enables a security telephone line for security and disaster prevention to be secured promptly and appropriate measures can be taken in the event of a disaster such as an earthquake. The present invention relates to a disaster prevention monitoring method and device.

[0002]

2. Description of the Related Art In the case of city gas, electricity, water supply, transportation facilities, etc., various control facilities are often centrally monitored at a monitoring (management) center. As typical examples of this centralized monitoring system, there are actually a dedicated line system that connects the terminal to be monitored and the center with a dedicated line, a public telephone line system that connects with a public telephone line, and a wireless communication system that connects with a wireless communication line. It has been put to practical use.

[0003]

However, the above method has the following drawbacks. Dedicated line system This system is not so large in a small-scale centralized monitoring system, but the equipment cost becomes huge in a wide-area and large-scale centralized management system such as city gas. Also, in the event of an earthquake, there is a high possibility that communication will not be possible due to the breakage of the dedicated line, the collapse of the equipment, etc. Public telephone line system This system has relatively low facility costs, but when a large-scale disaster occurs, ordinary telephones concentrate and make calls (communication).
Due to congestion, call restrictions are given to prioritize emergency calls for disaster countermeasures. Therefore, for example, in the case of city gas, etc., it will be difficult to obtain information from pressure regulating bases (governor bases), seismographs, emergency shutoff valves, emergency gas diffusion towers, etc., which are scattered in hundreds of locations in the gas pipeline network. There is a concern that measures will be delayed. Wireless communication system This system requires huge cost for equipment.

SUMMARY OF THE INVENTION The present invention secures a telephone line at the same time as a disaster occurs while using a telephone line that is relatively inexpensive to install, and monitors before calls are concentrated or call restrictions are imposed. The purpose is to propose a method and an apparatus for collecting necessary information between the target terminal and the monitoring center, and the configuration is as follows. 1. In addition to installing a slave station mobile phone on the monitored terminal side,
A mobile phone line is installed on the side of the monitoring center to automatically establish a mobile phone line between the slave station and the master station in the event of a disaster of a preset size or larger. Remote security and disaster prevention monitoring method. 2. Installed a slave station mobile phone on the monitored terminal side, installed the same number of parent station mobile phones as the slave station mobile phones on the monitoring center side, and installed a disaster sensing device and this sensing device on the monitored terminal side to detect a disaster. Then, an emergency automatic calling device for driving the slave station mobile phone to secure a mobile phone line between the slave station and the master station is provided. 3. 3. The remote security and disaster prevention monitoring device using a mobile phone line according to the above 2, wherein a smaller number of mobile phone base stations than the number of mobile phone base stations are installed. 4. Installed mobile phones at each business site and installed the same number of mobile phones for emergency contact on the monitoring center side, and the monitoring center started to collect disaster information with the terminals to be monitored. Immediately after that, a mobile phone for emergency contact and a mobile phone line for business establishments were immediately secured to construct an emergency disaster information communication network for transmitting disaster information to each business establishment. Remote security and disaster prevention monitoring device by telephone line. INDUSTRIAL APPLICABILITY The present invention can be applied to any centralized monitoring system including a security / disaster prevention monitoring system for city gas, electric power, water, transportation and the like. The mobile phone referred to in the present invention has a PH
Also includes S.

[0005]

In the case of an earthquake, for example, when an earthquake with a seismic intensity of 5 or more occurs, a signal is input from the earthquake detection device to the emergency automatic calling device. When this signal is input, the emergency automatic calling device immediately uses the mobile phone of the slave station to call the predetermined mobile phone of the master station to secure the mobile phone line between the slave station and the master station. , Send the earthquake information from the slave station to the master station. The monitoring center instantly determines whether or not earthquake information exists in the collected information, and if it exists, it automatically sends a "continuous information collection command" to the mobile station mobile phone on the terminal side,
Secure the line continuously. In addition, the monitoring center immediately makes a call by the "continuous information collection command" to the mobile station mobile phone of the terminal that has not made a call, and the line is continuously secured. In other words, it will be possible to continuously collect information online with all mobile stations until the situation stabilizes. Normally, the time required to collect such emergency information is 2 to
It takes about 3 minutes.

[0006] Next, it is possible to install a small number, for example, ⅕ to ⅙ of the mobile stations of the slave station, to the number of the mobile stations of the slave station. For communication at this time, one master station owns a plurality of slave stations. Therefore, if the line is already blocked, it waits while retrying. If a mobile telephone line and a public telephone line are provided together, this line is used when the mobile telephone line cannot be used and the public telephone line side is in a state in which a call is possible. In such a situation, when multiple stations (slave station or master station) catch disaster information (for example, earthquake motion above a certain level), the slave station (terminal) automatically calls the specific mobile phone of the master station. , Data is transmitted to the master station (monitoring center). The parent station determines whether or not there is earthquake information in the information. If it exists, the master station sequentially calls the slave stations using all of the connected mobile phones of the master station after one and a half minutes, and collects information of all the slave stations within one minute. That is, information is collected when the situation of the slave station becomes stable. In addition, there are many offices in remote places, not in the monitoring terminal, and if you want to transmit emergency information to this office, call the office mobile phone from the monitoring center side with an emergency mobile phone to secure the line, The information collected from the slave station is transmitted.

You may make it use S. At this time, the digital adapter is replaced with a modem.

The remote security and disaster prevention monitoring system has the following functions. Communication between the monitoring center 1 side and the pressure regulating base 10 side in normal business is performed between the wireless station 7 of the terminal of the public telephone line 6 and the slave station mobile phone 17. Next, when an earthquake occurs and the earthquake sensor 12 senses it, a signal is input from the earthquake sensor 12 to the emergency automatic calling device 16. When this seismic signal is input, the emergency automatic calling device 12 drives the slave station mobile phone 17 to call the master station mobile phone 4, and first secures the mobile phone line. In this way, when the child station mobile phone 17 and the parent station mobile phone 4 are connected,
Earthquake information is input to the communication control device 2 of the monitoring center 1 from the remote monitoring device body 15. The communication control device 2 sends a signal from the parent mobile phone 4 to the remote monitoring device main body 15 via the small mobile phone 17 based on the input information,
Further, it collects necessary earthquake information and sends control signals to the governor 13, the shutoff valve 13a, and the like. The above communication is performed by immediately activating the mobile phone line when an earthquake is detected.

Next, the above embodiment is a basic operation example in the case where the master station mobile phone 4 and the slave station mobile phone 17 are installed in a one-to-one relationship. Even if the following operation is performed, Good.
For example, if an earthquake detector is attached to the mobile phone 4 side of the parent station and the child station or the parent station catches disaster information (for example, an earthquake motion of a certain level or more), the child station automatically carries the specified cell phone of the parent station. Call the phone and transfer the data to the master station. The master station instantly determines whether or not there is earthquake information in the information, and if there is, it automatically sends a "continuous information collection command" to the slave station and continuously secures the line. In addition, the master station immediately and automatically calls the slave station which has not made a call by the "continuous information collection command" to continuously secure the line. In other words, it will be possible to continuously collect information online with all slave stations until the situation stabilizes. Usually, such time is about 2 to 3 minutes. After that, the line is opened and information is gathered by making periodic calls from the master station. Next, due to equipment cost reduction, etc.
We will also install multiple public telephone lines for normal business. At this time, the lines should be used properly, such that ordinary data collection should be done through public telephone lines and emergency data collection should be done through mobile telephone lines. In this situation, when multiple stations (slave station or master station) catch disaster information (for example, earthquake motion above a certain level), the slave station automatically calls the specific mobile phone of the master station and the master station Data is transmitted to. The parent station determines whether or not there is earthquake information in the information. If it exists, the master station will call all the connected mobile phones one and a half minutes later and call the slave stations sequentially.
Collect information for all slave stations within 1 minute. That is, information is collected when the situation of the slave station becomes stable. After that, information gathering by regular calling is started. The communication between the emergency center 1 and the monitoring target terminal 10 is as described above. However, if there are a large number of business offices in remote areas, the business of the emergency disaster information communication network is provided for these business offices. Mobile phones 22, 27
Use to communicate emergency information.

[0010]

As described above, according to the present invention, when an earthquake or the like occurs, a mobile phone line is automatically secured to collect disaster information on the monitoring center side, and necessary control signals are transmitted to the terminal side. Since this is possible, the following effects can be obtained. a. A telephone line can be connected at the same time as a disaster occurs, and information can be collected and transmitted. As a result, most of the emergency information collection and emergency control can be ended before the telephone line is congested or the call restriction is imposed. b. In the case of a public telephone line, there is a high probability that the facility will be destroyed due to a disaster and it will be impossible to call, but mobile phones (wireless)
Since the communication is carried out in, there is a very low probability that this call cannot be made. c. The mobile phone system according to the present invention has the advantages that the probability of non-communication due to a disaster is lower than the leased line and public line systems, and the facility cost is lower than the wireless system. d. INDUSTRIAL APPLICABILITY The present invention is effective when applied to any centralized control system such as city gas, electricity, water supply, transportation and other facilities. e. By using the emergency disaster information communication network, emergency information can be reliably transmitted from the monitoring center to each business office. f. If the PHS is used instead of the mobile phone for the slave station and the mobile phone for the parent station, and the mobile phone for the office and the mobile phone for emergency contact, the system can be constructed and operated at low cost.
