Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a discharge warning system, and more particularly, to a system for recommending evacuation from a dangerous water area due to an increase in river water level due to discharge of a dam.
[0002]
Due to torrential rains that occurred frequently during the rainy season such as June to July, there were many cases where people who were fishing in Nakasu and those who were recreationing on the riverbank were late to the disaster.
[0003]
The dam management system has been introduced under the critical role of preventing downstream residents from flooding, so it has not been able to cope with such a sudden disaster. Therefore, in the future, it is required to be able to quickly and surely prevent disasters even in the event of a sudden major disaster. Therefore, there is a need for a technology that can reliably issue a warning to a specific large number of people “people in the danger zone”.
[0004]
[Prior art]
In a conventional discharge warning system, after starting discharge, a discharge warning facility such as a siren or speaker is installed at a position where the downstream water level rises 30 cm in 30 minutes, and the discharge warning facility is remotely controlled by wire / wireless from the dam management office. The warning was given to the inhabitants of the downstream.
[0005]
[Problems to be solved by the invention]
However, since the conventional discharge warning system has issued warnings to the downstream residents, the downstream residents' voices are “noisy, harsh” and “the voice is loud and affects livestock”. Not.
[0006]
Furthermore, since only one-way warnings are issued to unspecified number of people, it is impossible to confirm whether a person has evacuated from the danger zone in real time with a conventional discharge warning system. It was. In fact, it can be confirmed only by patrol of the basin by the staff of the dam management office.
[0007]
The present invention has been made in view of these points, and recommends evacuation by calling a person carrying a mobile device in the vicinity of a river, and in real time that a person has evacuated from a danger zone. The purpose is to provide a discharge warning system that can be confirmed.
[0008]
[Means for Solving the Problems]
FIG. 1 shows the principle of the present invention.
As shown in this figure, according to the present invention, a base station 4 that is installed around a river and performs wireless communication with the mobile device 2 and a location around the river based on information obtained by the communication. The position search means 6 for acquiring the position information and telephone number of the mobile device 2 to be operated, and the position search means based on the discharge information from the dam lake to the river 3 or the water level information of the river 3 input from the dam management system 8 6, the search activation means 10 that requests acquisition of the location information and telephone number of the mobile device 2 located around the river, the location information and the telephone of the mobile device 2 located around the river obtained by the location search means 6. There is provided a discharge warning system characterized by comprising position information display means 12 for displaying a number on the first screen.
[0009]
According to the above configuration, the search activation means 10 is based on the discharge information from the dam lake to the river or the water level information of the river 3 input from the dam management system 8, for example, the start of discharge or the river When the water level exceeds the threshold, the position search means 6 is requested to acquire the position information and telephone number of the mobile device located around the river.
[0010]
The position search means 6 acquires the position information and telephone number of the mobile device 2 located around the river. The position information display means 12 displays the position information and telephone number of the mobile device 2 located around the river acquired by the position search means 6 on the first screen. Then, for example, a telephone number is manually dialed from a telephone and an evacuation recommendation is made to the mobile device 2.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 2 is a configuration diagram of the discharge warning system according to the embodiment of the present invention. FIG. 3 is a layout diagram of the discharge warning system according to the embodiment of the present invention.
[0012]
As shown in this figure, the discharge warning system includes a dam management system 20, a discharge control system 22, a position search system 40, a PHS network 52, and a plurality of base stations 54 # i (i = 1 to n).
[0013]
The dam management system 20 is provided in the dam management station 92 in FIG. 3, and controls the dam gate facilities and various data (gate opening, water level around the dam lake 90, river water level, upstream rainfall, etc.) Are collected and processed into data such as discharge flow rate and inflow rate, and “discharge information” and “river water level information” of a plurality of river areas (for example, upstream 106 / middle stream 108 / downstream 110) are input to the discharge control system 22. Output.
[0014]
The discharge control system 22 is provided in the dam management station 92 in FIG. 3, and the position information of the mobile device 56 located around the river is automatically / manually according to the discharge information from the dam management system 20 or the water level information of the river. A “location search system activation” signal instructing the search of the telephone number is transmitted to the location search system 40, the map around the river 94, the location information of the mobile device 56 transmitted from the location search system 40, and the screen of the phone number Display and dial the mobile unit 56 automatically / manually to make an evacuation recommendation.
[0015]
In addition, the mobile device 56 communicates with the discharge control system 22 through the base station 54 # i (i = 1 to n) that can be widely used and can cover a river area excluding people's houses as a service area. It must be possible. Examples of the mobile device 56 that satisfies such conditions include a PHS with a relatively small service area. In the present embodiment, the mobile device 56 is referred to as a PHS 56.
[0016]
The discharge control system 22 includes a console 24, sequence units 26 and 27, a router 28, a LAN 30, a location information terminal 32, a map database 34, a telephone response notification device 36, and a telephone 38.
[0017]
The console 24 inputs “release information” or “river water level information” from the dam management system 20 and outputs “release information” or “river water level information” to a display unit such as an LED. The position search system 40 is activated, automatic / manual setting information is output to the position information terminal 32, “release information” and “river water level information” are output to the telephone response reporting device 36, and a stop switch 78 described later is provided. The position search system 40 is activated at a constant interval until the position information terminal 32 is turned on or the activation / deactivation is instructed from the position information terminal 32.
[0018]
4 (a) and 4 (b) are diagrams showing a console. In particular, FIG. 4 (a) shows a key switch and a touch panel, and FIG. 4 (b) shows a display unit. The console 24 includes a key switch 72 and a touch panel 74 as shown in FIG. 4A, and a display unit 80 made of LEDs and a microprocessor (not shown) as shown in FIG. 4B.
[0019]
The key switch 72 is a switch for setting whether to activate the position search system 40 manually / automatically, and is connected to the microprocessor. The touch panel 74 includes a system start panel 76 for instructing start of the position search system 40 and a system stop panel 78 for instructing start / stop of the position search system 40, and is connected to the microprocessor.
[0020]
The display unit 80 includes an LED 82 that outputs discharge start information, an LED 84 that outputs a water level abnormality, an LED 86 that outputs a system abnormality, and an LED 88 that outputs upstream / middle / downstream water level information, and is connected to the microprocessor.
[0021]
The processor executes software having the following functions.
(1) When the key switch 72 is manually operated and the system activation panel 76 is turned on, a “position retrieval system activation” signal (for example, a pulse signal) instructing activation of the position retrieval system 40 is sent to the sequence unit 26.
[0022]
(2) When the key switch 72 is automatically set, the “release information” / “river water level information” input from the dam discharge system 20 makes a recommendation for evacuation (for example, “release information” indicates the release start or river water level information) Is satisfied), a “position search system activation” signal for instructing activation of the position search system 40 is sent to the sequence unit 26.
[0023]
(3) The “release information” / “river water level information” input from the dam management system 20 is displayed on the display unit 80.
(4) The automatic / manual setting information of the key switch 72 is output to the position information terminal 32, and "release information" and "river water level information" are output to the telephone response reporting device 36.
[0024]
(5) When the key switch 72 is automatically set, if the conditions for making the above evacuation recommendation are satisfied, the position search system 40 is started at regular intervals until the start stop signal is received from the position information terminal 32. A “position search system activation” signal is sent to the sequence unit 26.
[0025]
(6) If the key switch 72 is set manually, a “position search system activation” signal that instructs the activation of the position search system 40 at a constant interval is sent to the sequence unit 26 until the system stop panel 78 is turned on. Send it out. The reason why the activation signal is transmitted at regular intervals as in (5) and (6) is to confirm that the PHS 56 located around the river 94 has evacuated.
[0026]
The console 24, the position information terminal 32, and the telephone response reporting device 36 are connected by, for example, RS232C. When receiving the “position search system activation” signal from the console 24, the sequence unit 26 is, for example, a programmable logic controller that transmits a “position search system activation” signal according to the interface on the position search system 46 side.
[0027]
The sequence unit 27 is a transmission device that transmits a “position search system activation” signal to the system server 44 when receiving a “position search system activation” signal from the sequence unit 26. The sequence units 26 and 27 are connected by, for example, a dedicated line. The router 28 is for connecting to the position search system 40 via the LAN 30.
[0028]
The position information terminal 32 is, for example, a personal computer having the following functions.
(1) The location information and telephone number of the PHS 56 located around the river 94 received from the system server 44 are displayed on the display together with the map around the river 94 stored in the map database 34.
[0029]
{Circle around (2)} When the key switch 72 is automatically set, a communication flag indicating that these pieces of information are significant is added to the telephone number and the position information, and the result is output to the telephone response notification device 36.
[0030]
(3) When the PHS 56 located around the river 94 disappears, a start / stop signal is output to the console 24.
As a communication protocol between the system server 44 and the location information terminal 32, for example, a TCP / IP protocol is used. The position information is information indicating the position of the base station 54 # i where the PHS 56 is located, and is, for example, the latitude / longitude of the base station 54 # i. The position information terminal 32 and the telephone response reporting device 36 are connected by, for example, RS232C. The map database 34 is a database that stores map information around the river 94.
[0031]
The telephone response notifying device 36 includes a voice recording unit, a table, a sound piece generating unit, and a control unit. The voice storage unit is a recording medium in which a plurality of voice messages corresponding to “release information” and “water level information” are stored in advance, and is, for example, an IC-ROM card.
[0032]
The reason for storing a plurality of voice messages is to send a voice message corresponding to the emergency level of evacuation (for example, caution warning, emergency evacuation, etc.) according to "release information" and "water level information". is there.
[0033]
The combination of “release information” and “water level information” allows voice messages to be sent when the same “water level information” is sent or not depending on the presence or absence of “release information”. Because there is. For example, if the “water level information” has not reached the dangerous water level, but the discharge has started, there is a risk that the water level will rise rapidly.
[0034]
The table stores the relationship between position information and river areas (for example, upstream 106, middle stream 108, and downstream 106). This is because the water level information may differ depending on the river region. The sound piece generation unit reads out and reproduces a voice message corresponding to the water level information of the river region corresponding to the input position information from the voice storage unit. The voice control unit automatically dials the input telephone number to the public network, and sends the voice message reproduced by the sound piece generation unit to the telephone line.
[0035]
The telephone 38 is used by a staff member to dial the PHS 56 and make an evacuation recommendation via the PHS network 52. In this example, the telephone set 38 is connected to the telephone answering / reporting device 36, but of course, it may be connected directly to the telephone line.
[0036]
The position search system 40 includes a system server 44, a LAN 46, and a router 48. Upon receiving the activation signal from the sequence unit 27, the system server 44 searches the PHS 56 carried by the person 104 located around the river 94 through the PHS network 52 and the base station 54 # i (i = 1 to n), and The location information and the telephone number are notified to the discharge control system 22 through the LAN 46 and the router 48 according to the TCP / IP protocol.
[0037]
The area around the river 94 to be searched by the system server 44 is, for example, a service area of a base station 54 # i (i = 1 to n) that is registered in the database in advance and arranged around the river 94. It is specified by a number (base station ID).
[0038]
The telephone number of the PHS 56 may be acquired from the PHS 56 when the base station 54 # i (i = 1 to n) issues a response instruction to the PHS 56 at the time of position search, or when an authentication request is made to the PHS 56, You may acquire from the database which the PHS network 52 has from the authentication number which PHS56 sets.
[0039]
The router 48 is for connecting the system server 44 and the discharge control system 22 via the LAN 46. The reason why the system server 44 and the discharge control system 22 are connected by a router is that the system server 44 is generally located at a remote place from the dam management station 92.
[0040]
The PHS network 52 is a PHS public network. The base station 54 # i (i = 1 to n) is preferably installed so as to cover the service area without omission except for the houses around the river 94 shown in FIG. When stations are limited, be sure to install them in dangerous areas such as the rocky area 100 and Nakashu 102.
[0041]
The base station 54 # i (i = 1 to n) is arranged indoors in the discharge warning facility 96 that has already been installed or in an existing / new utility pole. The PHS 56 is an ordinary mobile device that is carried by the person 104 to make a call, and is not special.
[0042]
FIG. 5 is a flowchart of the process.
Hereinafter, the operation of the discharge warning system of FIG. 2 will be described with reference to FIG.
(A) Dam management system 20
The dam management system 20 collects dam gate equipment control and various data (gate opening, water level around the dam lake 90, water level of upper, middle and downstream rivers, upstream rainfall, etc.), and discharge and inflow. It is processed into data such as quantity.
[0043]
Then, as shown in FIG. 5, when the “river water level information” of the upstream 106, the middle stream 108, and the downstream 110 of the river is periodically released, the “release information” together with the “river water level information” is displayed on the console 24. Output.
[0044]
(B) Activation of the position search system 40 The staff of the dam management center 92 sets the key switch 72 of the console 24 to manual / automatic. The console 24 displays “release information”, “river water level information” and the like input from the dam management system 20 on the corresponding LEDs of the display unit 80.
[0045]
When the key switch 72 is set to manual, the staff looks at the “release information” and the “river water level information” displayed on the display unit 80, and when it is necessary to make an evacuation advisory, Press the panel. When the panel for system activation 76 is pressed, the console 24 outputs a “position search system activation” signal to the sequence unit 26.
[0046]
When the key switch 72 is set to automatic, the console 24 satisfies the activation conditions of the position search system 40 for “release information” and “river water level information” (for example, “release start” or “river water level is constant”). When the value is exceeded "), a" position search system activation "signal is output to the sequence unit 26. The activation conditions are programmed in advance.
[0047]
The console 24 outputs manual / automatic setting information of the key switch 72 to the position information terminal 32 and outputs “river water level information” to the telephone response reporting device 36. When receiving the “position search system activation” signal, the sequence unit 26 transmits the signal to the sequence unit 27 on the position search system 40 side according to a certain interface. When receiving the “position search system activation” signal, the sequence unit 27 outputs the signal to the system server 44.
[0048]
(C) When the position information and telephone number acquisition system server 44 receives the “position search system activation” signal, the system server 44 transmits information about the vicinity of the river 94 that is the search target registered in the database in advance through the PHS network 52. A location search is instructed to the base station 54 # i (i = 1 to n) corresponding to the service area number.
[0049]
The base station 54 # i (i = 1 to n) makes a response request to the PHS 56 located in the service area 60 # i of the own station using the control channel. The PHS 56 located in the service area 60 # i responds according to the response request from the base station 54 # i and notifies the base station 54 # i of its telephone number.
[0050]
In addition, since the position search of the portable person of PHS56 is concerned with a portable person's privacy, after obtaining the permission (for example, switch is turned on) of the portable person of PHS56, from base station 54 # i (i = 1-n) In general, the PHS 56 makes a response to the search response request to the PHS 56.
[0051]
However, since the PHS network 52 registers the position of the PHS 56 in the database and knows in which service area the PHS 56 is located, if the public nature is more important than privacy, a search response request is not made. It is also possible to search the database to obtain the PHS 56 located in the search target service area 60 # i and the telephone number of the PHS 56.
[0052]
The system server 44 uses the LAN 46, the routers 48 and 28, and the LAN 30 according to the TCP / IP protocol according to the location information (for example, the latitude and longitude of the base station 54 # i) and the telephone number of the PHS 56 located around the river 94. Transmit to the location information terminal 32. When a plurality of PHSs 56 are located around the river 94, the system server 44 sequentially transmits position information and a telephone number to the position information terminal 32.
[0053]
(D) Display of position information and telephone number When the position information terminal 32 receives the position information and telephone number of the PHS 56 located around the river 94, it displays the map information around the river 94 stored in the map database 34. And location information and a telephone number are displayed on the corresponding map.
[0054]
(E) When the manual transmission key switch 72 is set to manual in the PHS 56, the staff looks at the position information and the telephone number displayed on the position information terminal 32 and dials the PHS 56 from the telephone 38. An incoming call is received at the dialed PHS 56, and the staff makes an evacuation recommendation according to “release information” and “river water level information” to the carrier 102 of the PHS 56. The carrier 104 of the PHS 56 can hear the voice message and evacuate from the river 94.
[0055]
(F) When the automatic transmission key switch 72 is set to automatic in the PHS 56, when the location information terminal 32 receives location information and a telephone number, the communication flag is turned on and attached to (location information + phone number). , According to the RS232C interface, the data is output to the telephone response notifying device 36. The voice control unit of the telephone response reporting device 36 checks the communication flag, and if the communication flag is on, takes in position information and a telephone number.
[0056]
The voice control unit dials the telephone number to the public network. The dialed PHS 56 is received from the base station 54 # i via the telephone line and the PHS network 52. The voice control unit to which the PHS 56 makes an incoming call response instructs the sound piece generation unit to reproduce the voice message.
[0057]
The voice control unit obtains “river water level information” input from the console 24 corresponding to “position information” from the table, reads out a voice message corresponding to “river water level information” from the voice storage unit, and reproduces it.
[0058]
For “river water level information” that does not satisfy the dangerous water level for which evacuation is advised, no voice message is registered. In this case, the voice message corresponding to “release information” is read from the voice storage unit, Reproduce.
[0059]
The voice control unit transmits the voice message reproduced by the sound piece generation unit to the PHS 56 via the telephone line, the PHS network 52, and the base station 54 # i. The carrier 104 of the PHS 56 can hear the voice message and evacuate from the river 94.
[0060]
(G) When the evacuation confirmation key switch 72 is set manually and the system activation panel 76 is pressed, the console 24 sends a “position search system activation” signal via the sequence units 26 and 27 at regular intervals. To the system server 44. As described above, when receiving the “position search system activation” signal, the system server 44 transmits the position information and telephone number of the PHS 56 located around the river 94 to the position information terminal 32.
[0061]
The location information terminal 32 displays location information and a telephone number on the display together with a map around the river 94. The staff looks at the location information etc. displayed on the display and determines whether all of them have evacuated. Accordingly, an alarm can be issued to a specific person while checking the position on the position information terminal 32 in real time.
[0062]
If the user has not evacuated, he calls the PHS 56 again using the telephone 38 and makes an evacuation recommendation. Upon confirming the evacuation of all members, the staff pushes the system stop panel 78. The console 24 stops sending the “position search system activation” signal.
[0063]
If the key switch 72 is automatically set, the start / stop signal is not sent from the position information terminal 32, and the start condition of the position search system 40 is satisfied, the console 24 displays the “position search system at regular intervals. The “startup” signal is transmitted to the system server 44 via the sequence units 26 and 27. As described above, when receiving the “position search system activation” signal, the system server 44 transmits the position information and telephone number of the PHS 56 located around the river 94 to the position information terminal 32.
[0064]
The location information terminal 32 displays location information and a telephone number on the display together with a map around the river 94, adds a communication flag to the location information and the phone number, and outputs them to the telephone response notification device 36. As described above, the telephone response reporting device 36 automatically makes a call to a telephone number and outputs a voice message.
[0065]
Thereby, even if it is automatically set, evacuation advice can be continuously performed. When the location information terminal 32 no longer receives location information and a telephone number from the system server 44, the location information terminal 32 outputs a start / stop signal to the console 24. The console 24 stops activation of the movement search system 44 when the activation stop signal is input.
[0066]
According to the embodiment described above, at a dam management office where the number of people is decreasing, a warning can be given to a specific person before the river basin becomes dangerous due to heavy rain, etc. Can also be confirmed reliably. Since PHS can also be purchased at a considerably low price as a trend in the world, it can be easily tackled as a disaster countermeasure by the general population.
[0067]
【The invention's effect】
As described above, according to the present invention, an alarm can be issued to a specific person before the river basin becomes dangerous due to a heavy rain or the like, and it can be confirmed with certainty that the person has evacuated.
