Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a network configuration method for an alarm system.
In particular, urgent warning information such as advisories, alerts, evacuation orders, etc. for debris flows, mudflows, mudflows, etc. caused by localized heavy rains, and advisories, warnings, evacuation orders, etc. for tsunamis, etc. caused by earthquakes. The present invention relates to a system for configuring a reporting network that is optimal for reporting to various locations in a timely manner.

The following are advisories, warnings, etc. regarding debris flows, mudflows, mudflows, etc. (hereinafter referred to as debris flows, etc.) caused by localized heavy rains.
An example of a network for reporting evacuation orders, etc. (hereinafter referred to as warning information) will be explained.

Conventional rainfall observation systems include wide-area systems such as the AMeDAS system, but this system is not suitable for reporting warning information that is relatively regional and urgent, such as disasters caused by localized heavy rain. is inappropriate.

The present invention is proposed in view of the above-mentioned current situation. The purpose of this invention is to obtain a network configuration method for an alarm system that can accurately report necessary warning information in a short time.

In order to achieve this goal, in the present invention, the flexibility of reporting and the communication between the upper valley flow monitoring station in the mountainous area where disasters frequently occur due to localized heavy rain and the warning receiving station which is the destination of warning information are improved. In addition, the alarm receiving station will be connected with a public communication line (subscription telephone line, etc.) taking into account the distance between the two stations, and will also install a device to transmit the notification to the alarm receiving station, taking into account the cost of the forecaster's absence. For example, the system was configured so that reports from the monitoring station could be transferred to a forecaster's location using a public communication line.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

The drawing is a configuration diagram of a network for explaining the present invention in detail.

As shown in the drawing, the observation network includes, for example, observation station A1 in a mountainous area.
~Monitoring station B installed in a remote location from An and monitoring station B
The alarm transmission destination E and the alarm receiving station are connected by public communication lines, and if necessary, the alarm transfer destination E and the alarm receiving station are connected by public communication lines. This network is constructed.

Observation stations A and -An each add a unique station identification code set for each of the rainfall observation unit 1, observation station A, and ~An using, for example, a tipping cubicle rain gauge, to the observation data from observation unit 1. The observation unit 1 includes a code addition unit 2 for transmitting the coded observation data, and a transmission unit 3 for wirelessly transmitting the coded observation data from the code addition unit 2. A code adding section 2 adds a station identification code unique to the observation station to this rainfall pulse signal, and a transmitting section 3 superimposes it on an acid solution, which is then radiated by an antenna 4.

In the above operation, the station identification code is added, for example, as follows. In other words, each of the observation stations A to An is given its own station identification code by a combination of two types of fc AC signals with different frequencies, and the code adding section 2 adds the rainfall pulse signal including the station identification code. It is converted into a pulse signal (this pulse signal is hereinafter referred to as a coded pulse signal). With this configuration, multiple observation stations A, -
Observation signals can be transmitted from An using radio waves of the same frequency.

In addition, as is clear from the above, each observation station Aj-An sends out the coded pulse signal one by one in real time every time it observes 1wn of rainfall, and detects the rainfall within the observation stations A□ to An. Data processing, such as processing into cumulative rainfall, hourly rainfall, etc., is not performed.

The monitoring station B includes a receiving unit 12 that receives all the observation data (coded pulse signals) from the observation stations A and An, and a station identification code discriminating unit in the coded pulse signal received by the receiving unit 12. a code discriminator 13 that identifies the observation station to which the observed observation data is sent; a voice synthesizer 16 that converts the warning information into voice if it is sent through the code discriminator 13'; and a voice synthesizer 16 that converts the warning information into voice; It also includes a network control unit 17 for connecting the network and public communication network C, and an automatic dialing unit 18 for transmitting the dial number of the alarm receiving station via the network control unit 17.

When a radio wave containing a coded pulse signal is emitted from the observation stations A, ~An that observed rainfall by the above operation, for example, every time it rains 1-, this radio wave is received by the antenna 11, demodulated by the receiver 12, and transmitted to the receiver 12. - If the coded pulse signal is not a coded pulse signal, the coded pulse signal is discriminated by the code discriminating section 13, and the observation data (rainfall pulse signal) is inputted to the data processing section 14 together with the station identification code.

The data processing unit 14 aggregates the rainfall pulse signals for each observation station A1 to An based on the station identification code input as described above and according to the processing program and processing data input in advance, and collects various data related to rainfall. For example, total 11 discharge data showing the total amount of rainfall from the rain start point to the present time, hourly rainfall data showing the amount of rainfall during a set time such as 1 minute, 1 hour, 3 hours, rainfall amount over time, etc. Rainfall change data, etc. (hereinafter collectively referred to as rainfall-related data) indicating changes in rainfall areas, etc. are created,
Further, by combining these rainfall-related data, if necessary, notification information according to the grade of the combination, such as a warning, a warning, or an evacuation order for debris flows, etc., is created.

The rainfall-related data and clean can information created as described above are displayed on the display section 15, and the above-mentioned warning information is converted into audio warning information in the voice synthesis section 16. The network control unit 17 is activated,
The dial number of the alarm receiving station is automatically sent from the automatic dialing section 18 and is transmitted to the communication line 21 in the public communication line network C.
is closed, and the above-mentioned audio warning signal is sent out from the monitoring station B.

The alarm receiving station receives the warning information sent from the monitoring station B by the above operation, and receives the receiving section 31 (including the network control function).

) and a transfer device 32 that transfers the warning information to other alarm transfer destinations as necessary. Incidentally, this alarm receiving station is generally installed at a public institution such as a local municipal office or fire department.

The warning information sent via the public communication network C (communication line 21) by the above operation is received by the receiving section 31, thereby recognizing the occurrence of a static notice. In this case, if the person in charge of forecasting is not present at the warning receiving station, for example at night, the forwarding device 32 sends tal as the warning forwarding destination E.
For example, if the forecaster's home is set, as soon as the warning information is received by the receiving unit 31, the forwarding device 32 will send out the dial number of the forecaster's home, and the forecaster's home dial number will be sent to the alarm receiving station and sent to the forecaster. The forecaster's home (alarm transfer destination E) is connected to the forecaster's home via a public communication network C (communication line 22), and the warning information is transferred to the forecaster's home.

In the above embodiment, since the warning information transferred from the information receiving station to the Majesty's report forwarding destination E is assembled by voice, the necessary equipment for the warning forwarding destination E may be a normal telephone, and therefore, the information is transferred to the dismissal transfer destination. Destination E can be set anywhere as long as it is connected to a public communication network, especially a subscriber telephone network.

Further, in the embodiment, the conversion of one warning information to audio is performed at the monitoring station B, but it may also be performed at the alarm receiving station. Particularly when warning information is to be visually displayed at an alarm receiving station, it is advantageous in terms of information processing to convert the warning information into audio at the alarm receiving station. In this case, it is easily possible to provide a lower-level alarm receiving station in a district that receives marriage announcement information only by voice, since the upper-level alarm receiving station is equipped with the transfer device 32e.

Note that the transfer device 32 can be a commercially available, well-known telephone transfer device (including a transfer service provided by Nippon Telegraph and Telephone Public Corporation, etc.).

Further, although the drawing shows one alarm reception station and one alarm transfer destination E, it is clear that the system can be operated even if each of them is a plurality of stations. In particular, as shown by the dotted lines in the figure, if the entire warning receiving area is divided into multiple areas and a warning receiving station is installed in each area (for example,
If the area is located in the A valley basin, or if a warning receiving station is installed in each of villages -Dm k), the observation data and station identification codes from observation stations A1 to An should be comprehensively determined. The data processing section 14 then automatically dials the dial section 18.
If the software (il-) is configured to send out all the dial numbers of the specified alarm receiving station, it is possible to optimally issue the notification information 4 to the areas that really need it.

As described above in detail, the present invention provides: a) Observation stations and monitoring stations are connected via wireless lines to transmit observation data in real time; monitoring stations and alarm receiving stations are connected via public communication lines; When bone loss information occurs, the communication network is configured so that the warning information is immediately transmitted to the bone information receiving station, and if necessary, the warning information can be transferred to another location from the alarm receiving station. Since the necessary warning information can be reliably conveyed to the person in charge in a short time, it is possible to provide a communication network that is particularly suitable for local disaster warning systems.

b) By connecting the observation station and the monitoring station with a wireless line, there are no restrictions on where the observation station can be installed, and there is no interruption of communication lines in the event of a disaster.

C) When transmitting observation data, the identification code of the observation station is added to the observation data, so even if many observation stations are installed, only one type of radio wave is required, and this allows the number of observation stations to be installed arbitrarily. and the receiving section of the monitoring station is extremely simplified.

d) By connecting the monitoring station and the alarm receiving station with a public line, there are no regional restrictions on the installation of the alarm receiving station, and especially when multiple alarm receiving stations are installed in different regions. Since the monitoring station can easily issue warning information for each region, warning information can be optimally provided to the regions that really need it.

The present invention is particularly effective for alarm systems that handle urgent information.

Although the above embodiment is an example in which the present invention is implemented in a local rainfall observation system, the present invention can easily be implemented in other warning systems that require urgent notification (for example, an earthquake notification system). do not have.
