FIG. 1 is a diagram illustrating a system configuration of a satellite communication system 1000 according to the embodiment.
The satellite communication system 1000 includes a first control station 1-1, a second control station 1-2, a control station 2, and a slave station 3. Each of the first control station 1-1, the second control station 1-2, the control station 2 and the slave station 3 is connected to be communicable with each other via the communication satellite 7. A plurality of gate control devices 6-1 to 6-n (n is an integer of 2 or more) is connected to the slave station 3. The gate is, for example, a sluice or a landlock. The gate control devices 6-1 to 6-n control opening and closing of the gate. In the following description, the first control station 1-1 and the second control station 1-2 are referred to as a control station (also referred to as “control station system”) 1 unless otherwise distinguished. In the following description, the gate control devices 6-1 to 6-n will be referred to as the gate control device 6 unless otherwise distinguished. In the following description, the slave station (sometimes referred to as “slave station system”) 3 and the gate control device 6 are collectively referred to as the machine side. The satellite communication system 1000 may include a plurality of control stations (also referred to as “control station system”) 2 and a plurality of aircraft sides.

  The first control station 1-1 is, for example, a facility provided in a government office (for example, a metropolitan government office, a prefectural office, a prefectural office, and a prefectural office) that is the center of a prefecture. The first control station 1-1 notifies emergency information to the slave station 3 via the communication satellite 7 in response to reception of J-ALERT (for example, notification of occurrence of a tsunami). Here, the emergency information is information indicating that a large-scale disaster has occurred, for example. In the following description, the occurrence of a large earthquake will be described as an example of J-ALERT. The first control station 1-1 controls the opening and closing of all sluices / land ridges under the jurisdiction of the control station (for example, in the case of a prefecture-based system, the prefecture). For example, the first control station 1-1 receives an instruction to close the sluice / land ridge in response to reception of J-ALERT or an instruction from the control station 2 (hereinafter referred to as “closing instruction”). 3, the gate controlled by the gate control device 6 is closed. Specific processing regarding the gate closing of the gate control device 6 will be described later. Further, the first control station 1-1 monitors the state of the second control station 1-2 by receiving signals transmitted from the second control station 1-2 to the control station 2 and the slave station 3.

The second control station 1-2 is, for example, equipment provided in the joint government building. The second control station 1-2 performs the same process as the first control station 1-1. Specifically, the second control station 1-2 notifies emergency information to the slave station 3 via the communication satellite 7 in response to reception of J-ALERT (for example, notification of occurrence of a tsunami). The second control station 1-2 controls the opening and closing of all sluices / land ridges under the jurisdiction of the control station (for example, in the case of a prefecture unit system, within the prefecture). For example, the second control station 1-2 receives the J-ALERT or sends a closing instruction to the slave station 3 in response to an instruction from the control station 2 to close the gate to the gate control device 6. Command. The second control station 1-2 also monitors the state of the first control station 1-1 by receiving signals transmitted from the first control station 1-1 to the control station 2 and the slave station 3.
The first control station 1-1 and the second control station 1-2 are not limited in the installation distance. However, considering the risk of a satellite line going down due to the effects of disasters such as earthquakes or guerrilla heavy rain, It is desirable to arrange them at remote locations.

The control station 2 is a facility provided in a control station such as a joint government building, a fire department, and a municipality. The control station 2 manages the aircraft side within its jurisdiction. The control station 2 transmits a closing instruction to the first control station 1-1 and the second control station 1-2 in accordance with instructions from the control station staff.
The slave station 3 is a facility provided near the gate control device 6. The slave station 3 sends information for controlling the opening and closing of the gate to the gate control device 6 connected to the slave station 3 in accordance with an instruction from the control station facility 1. For example, the slave station 3 instructs the gate control device 6 connected to the local station to close the gate in response to the closing command.
The communication satellite 7 relays satellite communication among the control station facility 1, the control station 2, and the slave station 3.

Further, the closing of the gate when J-ALERT (for example, notification of occurrence of a tsunami) is received is performed as follows.
When the first control station 1-1 and the second control station 1-2 receive J-ALERT (for example, notification of occurrence of a tsunami), the first control station 1-1 and the second control station 1-2 generate a closing instruction. The first control station 1-1 and the second control station 1-2 transmit the generated closing command to the slave station 3 via the communication satellite 7 through a simultaneous command line. The slave station 3 receives the closing instruction transmitted from the first control station 1-1 and the second control station 1-2. The slave station 3 instructs the gate control device 6 connected to the own station to close the gate according to the received closing command. In this way, the gate is automatically closed. Thereafter, the slave station 3 transmits a response indicating the gate state (for example, open / closed state) to the first control station 1-1 and the second control station 1-2 via the communication satellite 7.

Next, specific processing relating to closing of the gate controlled by the gate control device 6 will be described with reference to FIG.
The control station 2 transmits a closing command to the first control station 1-1 and the second control station 1-2 via the communication satellite 7 in accordance with the operation of the staff. Next, the first control station 1-1 and the second control station 1-2 transmit a close command to the slave station 3 via the communication satellite 7 in response to the received close command. In accordance with the received closing instruction, the slave station 3 instructs the gate control device 6 connected to the local station to close the gate and closes the gate. In this way, the gate is closed. Thereafter, the slave station 3 transmits a response indicating the gate state (for example, open / closed state) to the first control station 1-1 and the second control station 1-2 via the communication satellite 7. The first control station 1-1 and the second control station 1-2 transmit the received response to the control station 2.
Thus, in the satellite communication system 1000 according to the present embodiment, the same closing instruction is transmitted to the slave station 3 in each of the first control station 1-1 and the second control station 1-2. In addition, a simultaneous command line is used for the closing command. That is, the simultaneous command line is duplicated and the closing command is transmitted.

FIG. 2 is a diagram showing a communication configuration of the satellite communication system 1000 in the present embodiment.
Hereinafter, the signal flow of the satellite communication system 1000 according to the present embodiment will be described with reference to FIG. As shown in FIG. 2, the lines from the control station 1 to the control station 2 and the slave station 3 are down, and the lines from the control station 2 and the slave station 3 to the control station 1 are up.

  First, when a request is made from the control station 2, a request (for example, a closing command) is transmitted to the first control station 1-1 and the second control station 1-2. In response to the received request, the first control station 1-1 and the second control station 1-2 transmit a closing command to the slave station 3 using a simultaneous command line.

  For example, the first control station 1-1 transmits a closing command to the slave station 3 using the simultaneous command line 90. At this time, the first control station 1-1 transmits a close command to the slave station 3 using the 1-system downstream band. The second control station 1-2 monitors the downstream band of the first system. That is, the second control station 1-2 monitors the simultaneous command line 90. Further, for example, the second control station 1-2 transmits a closing command to the slave station 3 using the simultaneous command line 91. At this time, the second control station 1-2 transmits a close command to the slave station 3 by using the second downstream band. The first control station 1-1 monitors the downstream bandwidth of the second system. That is, the first control station 1-1 monitors the simultaneous command line 91.

  The slave station 3 instructs the gate control device 6 to control the opening and closing of the gate according to the closing command transmitted from the first control station 1-1 and the second control station 1-2, and the control result is the first as a response. It transmits to the control station 1-1 and the second control station 1-2. At this time, the slave station 3 transmits a response to the first control station 1-1 and the second control station 1-2 using the band. For example, the slave station 3 transmits a response to the first control station 1-1 using the 1-system upstream band. Further, for example, the slave station 3 transmits a response to the second control station 1-2 by using the upstream band of the second system. The first control station 1-1 and the second control station 1-2 receive the response transmitted from the slave station 3, and transmit the received response to the control station 2.

  For example, the first control station 1-1 transmits a response to the control station 2 using the simultaneous command line 92. At this time, the first control station 1-1 transmits a response to the control station 2 using the 1-system downstream band. The second control station 1-2 monitors the downstream band of the first system. That is, the second control station 1-2 monitors the simultaneous command line 92. Further, for example, the second control station 1-2 transmits a response to the control center 2 using the simultaneous command line 93. At this time, the second control station 1-2 transmits a response to the control station 2 by using the 2 system downstream band. The first control station 1-1 monitors the downstream bandwidth of the second system. That is, the first control station 1-1 monitors the simultaneous command line 93.

Next, the functional configuration of the control station will be described with reference to FIG. FIG. 3 is a block diagram illustrating an example of a functional configuration of the control station according to the embodiment.
The control station 1 in the present embodiment is a device that receives emergency information such as J-ALERT (National Instantaneous Warning System) from a predetermined government office such as the Fire Department via a communication satellite or the like. The control station 1 is arranged, for example, in a government building of a local public entity such as a prefectural office. The control station 1 manages the control station 2 and the slave station 3. The control station 1 transmits the received emergency information to the control station 2 and the slave station 3, and transmits control information for controlling the opening and closing of the gate controlled by the slave station 3. In the present embodiment, the gate to be controlled is, for example, a sluice that closes a waterway in a river or a port, or a land that closes a passage. Gates such as sluices and landlocks form part of the dyke by closing when a tsunami occurs. In the present embodiment, the remote monitoring control device 11 illustrated in FIG. 3 is illustrated as the control station 1, and the entire illustrated in FIG. In the present embodiment, “control” is described as an aspect of “operation” including manual operation, but both may be considered as the same meaning.

  In FIG. 3, the control station system 1 includes an antenna device 10, a remote monitoring control device 11, a monitoring terminal 12, a monitoring console 13, and a power supply facility 14.

The antenna device 10 receives a J-ALERT signal and transmits / receives a signal to / from a control station or a slave station. The antenna device 10 has an ODU (Out Door Unit) 101. The ODU 101 is attached to the front surface of the antenna and performs transmission processing and reception processing (transmission / reception processing) of signals transmitted and received with a communication satellite reflected by the antenna. The ODU 101 outputs a signal received from the communication satellite to the satellite communication device 112 described later. The ODU 101 also outputs a signal received from the satellite communication device 112 to the communication satellite.
The antenna device 10 is supplied with uninterruptible AC 100V power from the power supply facility 14 via the outdoor distribution board 102 (shown by * 1). The antenna device 10 is also supplied with a power supply of AC 100V of a power failure system from the power supply facility 14 via the outdoor distribution board 102 (shown by * 4). An uninterruptible power supply is a power supply that is supplied so that no power failure occurs even if there is an abnormality in the commercial power supply. A blackout power supply is a power failure if there is an abnormality in the commercial power supply. Power supply. When the uninterruptible power supply is supplied, the antenna device 10 can continue to operate even when the commercial power supply is stopped.
In the present embodiment, the ODU 101 is described as being included in the antenna device 10, but the ODU 101 may be arranged separately from the antenna device 10. Further, the entire antenna device 10 may be referred to as ODU.

  The remote monitoring control device 11 includes a satellite communication device 112, a line connection control device 113, a VSAT (Very Small Aperture Terminal) remote monitoring terminal 114, a central simultaneous command monitoring device 115, an L2-SW (Layer 2 Switch) 116, and a J-ALERT. It has a receiving device 117, an automatic failure notification device (including a router) 119, a time management device 120, a power supply unit 121, and an alarm display panel 122.

  The antenna device 10 is connected to the satellite communication device 112. The satellite communication device 112 separates the J-ALERT signal received from the ODU 101 of the antenna device 10 and the signal from the control station or the slave station. The satellite communication device 112 outputs the separated J-ALERT signal to the J-ALERT receiver 117. In addition, the satellite communication device 112 outputs a signal acquired from the separated control station 2 or slave station 3 to the line connection control device 113. Further, the satellite communication device 112 outputs the signal acquired from the line connection control device 113 to the antenna device 10.

  The satellite communication device 112 has an IDU (In Door Unit) function. The IDU modulates / demodulates a transmission / reception signal with a communication satellite transmitted / received by the ODU 101. The satellite communication device 112 demodulates the signal received from the communication satellite. When the signal is a control signal transmitted from the control station 2 or the slave station 3, the satellite communication device 112 outputs the demodulated signal to the line connection control device 113. Further, the satellite communication device 112 outputs the demodulated signal to the telephone 125 when the signal is a signal related to a satellite phone. Similarly, the satellite communication device 112 modulates the control signal acquired from the line connection control device 113 and the signal related to the satellite phone acquired from the telephone 125 and outputs the modulated signal to the ODU 101.

  The line connection control device 113 controls communication line connection with the control station 2 or the slave station 3. The communication with the control station 2 or the slave station 3 includes information related to opening / closing control of gates (water gates and landlocks). The line connection control device 113 establishes a communication line with the control station 2 or the slave station 3 that transmitted the signal based on the control signal transmitted from the control station 2 or the slave station 3 based on the signal acquired from the satellite communication device 112. . The line connection control device 113 controls the transmission destination based on the control signal acquired from the central simultaneous command monitoring device 115 when transmitting the control signal from the central simultaneous command monitoring device 115 to the control station 2 or the slave station 3. A communication line with the station 2 or the slave station 3 is established.

  The VSAT remote monitoring terminal 114 is a terminal device that monitors the control center 2 and the slave station 3 using the VSAT system. For example, the VSAT remote monitoring terminal 114 monitors the communication status with the control station 2 and the slave station 3 and displays whether or not there is any abnormality in the communication status. When there is a control station or a slave station in which the communication status is abnormal among the control stations and slave stations monitored by the remote monitoring and control device 11, the VSAT remote monitor terminal 114 determines whether the control station or the slave station has an abnormality. May be displayed. Whether or not there is an abnormality in the communication status can be determined by, for example, transmitting a predetermined command to the control station and the slave station and whether or not there is a response to the transmitted command. Whether there is an abnormality in the communication status may be determined periodically at predetermined time intervals.

The central simultaneous command monitoring device 115 controls and monitors the control station 2 and the slave station 3.
The central simultaneous command monitoring device 115 has a warning information acquisition function for acquiring warning information based on J-ALERT information exemplified as emergency information transmitted via a communication satellite from the J-ALERT receiver 117. When the J-ALERT receiver 117 receives a J-ALERT signal, the central simultaneous command monitoring device 115 opens a gate to be closed (slave station that transmits activation information to be described later) based on the J-ALERT information. You may make it select. For example, when the central simultaneous command monitoring device 115 monitors a plurality of regional slave stations, it outputs a simultaneous closure command to the slave stations belonging to the region where the tsunami occurs indicated by the J-ALERT information. To do.

The central simultaneous command monitoring device 115 has an activation information transmission function for transmitting activation information for activating the notification facility (information providing facility) based on the warning information. The notification facility is, for example, an information provision facility for notifying that the gates are closed all at once. The information providing facility is a broadcasting device that outputs a sound broadcast or an alarm using a display facility such as a rotating lamp or an electric bulletin board, a speaker, or the like. The activation information is, for example, an information provision facility simultaneous activation command (may be abbreviated as “simultaneous notification command”) for simultaneously activating information provision facilities.
The central simultaneous command monitoring device 115 outputs a simultaneous notification command to the monitored slave station. The slave station that has received the simultaneous notification command activates the information facilities all at once and notifies the vehicle, ship, pedestrian, etc. of the information that the gate is closed. The central simultaneous command monitoring device 115 outputs a simultaneous notification command so as to notify the periphery of the gate that the gate is operating and to secure time for the vehicle or the like to retreat inside the gate.

  In this embodiment, as will be described later with reference to FIGS. 6 and 7, the slave station system 3 that has received the simultaneous notification command from the central simultaneous command monitoring device 115 receives the simultaneous notification command and activates the information equipment all at once. Has a determination function for determining whether or not a predetermined condition is satisfied. The predetermined condition is satisfied, for example, when a predetermined time has elapsed since the information facilities were activated all at once. The slave station system 3 can count whether or not a predetermined time has elapsed by using, for example, a timer. The predetermined time may be a predetermined fixed time (for example, 5 minutes). Moreover, it may be set based on J-ALERT information such as the arrival time of a tsunami. Further, the predetermined condition may include, for example, a condition that no person or vehicle that hinders the closing of the gate is detected by a television camera, a sensor, or the like. The slave station system 3 has a control information transmission function for transmitting a simultaneous closing command that is control information for controlling a gate managed by the slave station system 3 when a predetermined condition is satisfied.

  On the other hand, the central simultaneous command monitoring device 115 may have a determination function for determining whether or not a predetermined condition is satisfied after the simultaneous notification command is transmitted, as will be described later with reference to FIG. The central simultaneous command monitoring device 115 may have a control information transmission function for transmitting a simultaneous closing command that is control information for controlling the gate when a predetermined condition is satisfied. The central simultaneous command monitoring device 115 may output a simultaneous closing command for simultaneously closing the gates controlled by the slave stations to the monitored slave stations via a communication satellite.

  Further, the central simultaneous command monitoring device 115 may acquire and monitor device information such as the gate closing status in the slave station system 3 that has output the simultaneous notification command. In addition to information on the opening / closing status of the gate, the device information may include, for example, the value of a water level meter installed on the gate, the sound collected by the microphone, and the video taken by the television camera. In addition, failure information notifying the failure of the control station or the slave station device may be included. In the present embodiment, the gate information indicating whether or not the gate is correctly opened and closed is particularly important. For example, if the gate to be closed by the slave station system 3 is not closed after the simultaneous notification command is transmitted, water may enter the levee due to water increase such as a tsunami. The central simultaneous command monitoring device 115 can determine whether or not the gate could not be closed by monitoring information such as a proximity sensor installed on the gate through the slave station system 3. The central simultaneous command monitoring device 115 transmits the acquired device information and monitoring result to the monitoring terminal 12, for example. The monitoring terminal 12 may display the transmitted device information and monitoring result on the monitor 127.

Further, the central simultaneous command monitoring device 115 may output a simultaneous notification command based on an instruction from the monitoring console 13. Further, the central simultaneous command monitoring device 115 may output a simultaneous notification command based on an instruction from the control center.
In addition, the central simultaneous command monitoring device 115 transmits J-ALERT information (for example, the fact that a tsunami is generated and the area where the tsunami is generated) to the control station 2, slave station 3, cable broadcasting, disaster prevention broadcasting, and other facilities. May be.
The central simultaneous command monitoring device 115 is realized (configured) using a PLC (programmable logic controller). That is, the central simultaneous command monitoring device 115 is described as a functional block having the above-described functions, and the functional blocks can be realized by software or hardware functions, for example. In the present embodiment, the function of the central simultaneous command monitoring device 115 can be realized by a program executed by the PLC. Also in the following description, the case where PLC or FA (Factory Automation) -PC is used is illustrated as a method of realizing the function illustrated in the functional block.

  The central simultaneous command monitoring device 115 receives a monitoring signal (shown by * 3) from an emergency generator 141 described later. The monitoring signal is a signal for monitoring the emergency generator 141, and for example, monitors the operating state of the emergency generator 141.

The L2-SW 116 is a network switch that connects devices in layer 2 (data link layer). The L2-SW 116 connects the central simultaneous command monitoring device 115, the time management device 120, and the alarm display panel 122 in the remote monitoring control device 11. Further, the L2-SW 116 connects the monitoring terminal control device 126 of the monitoring terminal 12 and the monitoring console processing device 131 of the monitoring console 13 so as to communicate with each other.
The L2-SW 116 receives a power failure signal from the uninterruptible power supply 143 (illustrated by * 2). The power failure signal is output from the uninterruptible power supply 143 to notify the stop of commercial power failure. When the stop signal is input, the L2-SW 116 outputs a signal for executing a shutdown process to the monitoring terminal control device 126, for example. The monitoring terminal control device 126 or the like that has received the signal can prevent a failure due to the power failure by executing the shutdown process before the power failure.

  The J-ALERT receiver 117 acquires a J-ALERT signal output by the satellite communication device 112 after being separated. The J-ALERT receiving device 117 acquires a J-ALERT signal from a communication satellite and also from an LGWAN (Local Government Wide Area Network). Further, the J-ALERT receiver 117 may acquire a J-ALERT signal via the Internet (not shown). The J-ALERT receiving device 117 outputs the acquired J-ALERT signal to the central simultaneous command monitoring device 115.

The J-ALERT receiving device 117 outputs warning information based on the acquired J-ALERT signal to the central simultaneous command monitoring device 115. The warning information includes information based on J-ALERT information. For example, when the J-ALERT information is a tsunami warning (large tsunami), it may include information such as the height of the tsunami in each place, the arrival time of the tsunami in each place, and the like.
The automatic failure notification device 119 detects an internal failure of the remote monitoring control device 11 and outputs information on the detected failure to the outside through a telephone line or the like.
The time management device 120 manages time. The time management device 120 may correct the time information used by the remote monitoring control device 11 based on information acquired from a server on the network, for example.
The power supply unit 121 receives a power supply of AC 100V from the power supply facility 14 (illustrated by * 1). That is, the remote monitoring control device 11 can continue to operate even when the power supply facility 14 is constantly supplied with power and the commercial power supply is stopped.
The warning display panel 122 displays warning information based on J-ALERT information. The alarm display panel 122 may display, for example, tsunami information, earthquake information, weather information, and the like.

The monitoring terminal 12 includes a telephone 125, a monitoring terminal control device 126, a monitor 127, and a power supply unit 128.
The telephone 125 makes an incoming call with a satellite telephone signal using the VSAT system via the satellite communication device 112 and makes a call. It is assumed that the telephone using the VSAT system is arranged in a control station and a slave station, which will be described later, and that the control station, the control station, and the slave station can make a call using the VSAT system.

The monitoring terminal control device 126 has a monitor 127. The monitoring terminal control device 126 graphically displays, for example, device information acquired from the remote monitoring control device 11 or information acquired via a network (not shown) on the monitor 127. . Moreover, you may make it display the image | video of the television camera acquired from the slave station on a monitor. It is assumed that FA-PC is used for the monitoring terminal control device 126. Since the FA-PC has a feature that the communication function and the image processing function are excellent, the monitoring terminal control device 126 can be used for the purpose of taking advantage of the feature of the FA-PC. For example, the monitoring terminal control device 126 may communicate with an FA-PC arranged in a control center system, which will be described later, and perform data communication executable between the PCs, such as sharing device information.
The power supply unit 128 receives power supply of AC 100V from the power supply facility 14 (illustrated by * 1). That is, the monitoring terminal 12 can continue to operate even when the power supply facility 14 is constantly supplied with power and the commercial power supply is stopped.

  The monitoring console 13 includes a monitoring console processing device 131, a touch monitor 132, an alarm operation indicator 133, and a power supply unit 134.

The monitoring console processing device 131 has a touch monitor 132. The monitoring console processing device 131 displays the monitoring result and device information transmitted from the control station system 1 acquired from the remote monitoring control device 11 on the touch monitor 132. The touch monitor 132 displays, for example, the opening / closing status of the gate managed by the control station system 1, the output status of the simultaneous notification command output to the slave station by the remote monitoring control device 11, the output status of the simultaneous closing command, and the like. . For example, when the gate to be closed by the simultaneous closing command is not closed, the monitoring console processing device 131 notifies the operator (operator) of the abnormality by displaying the gate that is not closed. The operator may operate the monitoring console processing device 131 based on information on the gate displayed on the touch monitor 132.
The touch monitor 132 may display a screen for manually opening and closing individual gates. In addition, the touch monitor displays a screen for selecting a slave station that is the target of a simultaneous alerting command or a simultaneous closing command, or a screen for selecting a gate that is the target of a simultaneous closing command in each slave station. You may make it do. The touch monitor may display a screen for controlling a device other than the gate. The touch monitor may display a screen showing the opening / closing status of the gate that cannot be controlled by the control station.
The monitoring console processing device 131 may have an operation panel including switches, lamps, and the like. On the operation panel, for example, a switch for opening and closing the gate and a lamp indicating the operation status of the gate may be arranged. A PLC is used for the monitoring console processing device 131.

The alarm operation indicator 133 may be configured to manually transmit a simultaneous alarm notification command or a simultaneous closing command. Further, the alarm operation display 133 may be able to command the activation of the information equipment to each slave station. . For example, an operation for instructing a selected slave station to output a siren sound from a speaker can be performed.
The power supply unit 134 is supplied with 100 VAC power from the power supply facility 14 (shown by * 1). That is, the monitoring console 13 can continue to operate even when the power supply facility 14 is constantly supplied with power and the commercial power supply is stopped.

The power supply facility 14 includes an emergency generator 141, a distribution board 142, an uninterruptible power supply (UPS) 143, and a lightning resistant transformer 144.
The power supply facility 14 supplies uninterruptible AC 100V power shown by * 1 to each load facility (antenna device 10, remote monitoring control device 11, monitoring terminal 12, and monitoring console 13). In addition, the power supply of AC 100V of the power failure system illustrated by * 4 is supplied to the antenna device 10. Moreover, the power failure signal illustrated by * 2 is output with respect to L2-SW116.
Since the power supply facility 14 can always supply power by the uninterruptible power supply 143, each load facility can continue to operate even when the commercial power supply is stopped. While the emergency generator 141 takes several seconds to start up, the uninterruptible power supply 143 can supply power in a few ms, so that it is possible to supply power quickly. On the other hand, the emergency generator 141 can supply power for a long time compared to the uninterruptible power supply 143, and thus can supply power for a long time. In the present embodiment, the power supply facility 14 includes the emergency generator 141 and the uninterruptible power supply 143, thereby enabling stable power supply in a short time and a long time.
The emergency generator 141 outputs a monitoring signal (shown by * 3) to the central simultaneous command monitoring device 115. Further, the uninterruptible power supply 143 outputs a power failure signal (shown by * 2) to the L2-SW 116.
The distribution board 142 has a function of a switching board for switching between a power supply from a commercial power supply and a power supply from the uninterruptible power supply 143. In other words, the distribution board 142 can switch between a power failure system power supply (illustrated by * 4) and an uninterruptible power supply (illustrated by * 1) and output them.
The lightning resistant transformer 144 is a transformer having high resistance to lightning strike, and reduces a surge voltage caused by the lightning strike.

  The power supply facility 14 in the present embodiment supplies the commercial power source as it is to the load when the commercial power source is normal. On the other hand, when the commercial power supply stops or when the commercial power supply is disturbed, the commercial power supply is disconnected and power is supplied from the inverter of the uninterruptible power supply 143. Therefore, when the commercial power supply is normal, no energy loss occurs due to the drive of the inverter. When the commercial power supply is normal, the battery inside the uninterruptible power supply 143 is in a no-load state, so that the battery hardly deteriorates. On the other hand, a predetermined time lag (several ms) is generated in the power supply from the time when the commercial power supply is disconnected until the power supply by the inverter is started. However, for example, by causing each load facility to have a predetermined capacity component, it is possible to prevent a decrease in voltage value. In addition, when the charge amount of the battery in the uninterruptible power supply 143 decreases, the voltage can be detected and the commercial power supply can be converted into direct current by a rectifier to automatically charge the battery.

Good.

Next, the first automatic gate operation process will be described with reference to FIG. FIG. 6 is a sequence diagram illustrating an example of a first automatic gate operation process according to the embodiment.
In FIG. 6, the first automatic gate operation processing is performed by the control station system 1 (illustrated as “control station”, which is the same in FIGS. 7 to 11) that has received J-ALERT. SAT-G-PLC unit 31 (illustrated by “SAT-G-PLC”. The same applies to FIGS. 7 to 11). An example is shown in which a simultaneous closing instruction is transmitted to the slave station system 3 and a closing instruction is transmitted from the slave station system 3 to the sluice / land land.

  The SAT-G-PLC unit 31 described in FIG. 6 is realized by the SAT-G-PLC function of the satellite communication control device 31 described in FIG.

  In FIG. 6, one slave station system 3 is shown, but a plurality of slave station systems 3 are arranged, and the other slave station systems 3 are not shown. It is assumed that the same processing is performed in each slave station system 3.

  First, the control station system 1 acquires J-ALERT transmitted via a communication satellite from the fire department 100 exemplified as a predetermined government office.

  The control station system 1 that has received the J-ALERT sends a simultaneous closing signal (a simultaneous closing command) to the SAT-G-PLC units 31 of all the slave station systems 3 and the control station system 2 (“control station”). The same applies to FIGS. 7 to 11).

  As described with reference to FIG. 4, the control center system 2 that has acquired the simultaneous closing signal touches the slave station system 3 to which the simultaneous closing signal has been transmitted and the information on the gates (water gates / land ridges) that are closed by the simultaneous closing signal. You may display on H.232 etc.

  In addition, the SAT-G-PLC unit 31 of the slave station system 3 that has acquired the simultaneous closing signal transmits a control signal for starting the information providing facility. When the information providing facility is activated, the gate is notified by a siren, announcement, or the like that the gate is closed.

The SAT-G-PLC unit 31 starts a timer after transmitting a control signal for starting the information providing facility. The value of the timer sets, for example, a predetermined time that can be retracted to the inside of the gate before the gate is closed after the simultaneous closing signal is transmitted and the information providing facility is activated. Different values may be set for the timer depending on the gate.
When the SAT-G-PLC unit 31 determines that a predetermined time has elapsed using a timer, the SAT-G-PLC unit 31 signals to close the gate to the G-PLC unit 602 of the gate to be closed (water gate or landlock). Send.

  By the way, in this embodiment, in the control station system 1 shown in FIG. 3, the central simultaneous command monitoring device 115 and the monitoring console processing device 131 are realized using a PLC. In the control station system 2 shown in FIG. 4, the satellite communication control device 212 and the monitoring console processing device 231 are realized using a PLC. Furthermore, in the slave station system 3 and the gate control device 6-n shown in FIG. 5, the satellite communication control device 31 and the G-PLC unit 602 are realized using a PLC.

PLC is superior to FA-PC in environmental resistance. FA-PC is a PC with excellent environmental resistance that is made on the assumption that it is used in factories and the like. FA-PC can be used in a temperature environment, for example, at 5 ° C to 40 ° C. Moreover, FA-PC can be used at a vibration resistant environment, for example, 1.96 m / s ² or less. On the other hand, the PLC can be used in a temperature environment, for example, at 0 ° C. to 50 ° C. Further, the PLC can be used at, for example, 9.8 m / s ² or less in a vibration-resistant environment. That is, PLC has an advantage over FA-PC in a temperature environment and a vibration-resistant environment.

  Further, the PLC has a more stable execution environment than the FA-PC in executing software. The FA-PC operates by executing application software that operates on an OS (Operating System), like a general-purpose PC. The OS contains many bugs, including known and unknown ones, and there are cases where it is necessary to frequently apply correction programs to correct bugs. Therefore, the use may be stopped when the OS bug is corrected. On the other hand, since the PLC operates dedicated software such as a ladder program, the software execution environment is more stable than the FA-PC that can execute a general-purpose application program. For example, while the PC executes a process of sequentially processing software in principle, the PLC operates as a state machine that can be expressed by a state transition that can be realized by a relay circuit. Therefore, in applications where the scan time based on the performance of the CPU of the PLC can be ignored, the PLC can operate stably without being affected by the software structure.

  Further, the PLC has a simple system configuration and high availability as compared with the FA-PC. FA-PC often uses movable members such as a CPU, a cooling fan that cools the inside of the housing, and an HDD. On the other hand, in the PLC, a movable member is rarely used, and it is unlikely that the operation stops due to a failure of the movable member.

  Therefore, the PLC can be expected to operate more reliably than the FA-PC when a disaster such as an earthquake occurs. In the present embodiment, stable operation can be expected for a long time by using a PLC for the central simultaneous command monitoring device 115 and the like.

  Note that it may be difficult to fully grasp device information and the like in a large-scale system that controls or monitors a plurality of gates only by the state of the device that can be expressed by the lighting state of a lamp that can be easily controlled by a PLC. is there. For example, when measuring measurement data such as the water level around the gate in time series, it was difficult to realize it only with PLC. Therefore, in the conventional system, information processing such as measurement data may be executed together with gate opening / closing control using the information processing capability of the FA-PC.

Therefore, in this embodiment, based on highly urgent emergency information acquired via the communication satellite, control for transmitting a command for controlling the opening / closing operation of the gate via the communication satellite, and for the gate acquired via the communication satellite The core functions of the gate operation device such as monitoring for monitoring information and manual operation for transmitting a command for manually operating the opening / closing operation of the gate via the communication satellite are configured by the PLC and acquired via the communication satellite. The history monitoring for monitoring the history of gate information is composed of an FA-PC having a monitor.
With the above configuration, it is possible to provide a gate operating device with high availability and excellent information processing capability.

  In the present embodiment, the PLC and the FA-PC are exemplified as separate apparatuses. However, when the PLC CPU and the FA-PC CPU are respectively provided, both may be configured as one apparatus. For example, you may use PLC which can build in the function of FA-PC.

Next, the second automatic gate operation process will be described with reference to FIG. FIG. 7 is a sequence diagram illustrating an example of a second automatic gate operation process according to the embodiment.
In FIG. 7, in the second automatic gate operation process, the control station system 1 that has received J-ALERT automatically transmits a simultaneous closing signal to the SAT-G-PLC unit 31 of the slave station system 3. The SAT-G-PLC unit 31 that has received the simultaneous closing signal transmits the simultaneous closing signal to the G-PLC unit 602 of the slave station system (gate control device) 6 and further receives the simultaneous closing signal. -Illustrates the case where the PLC unit 602 transmits a closing instruction to the sluice gate / land land. In this embodiment, since the slave station system 6 is implemented by the gate control device 6, the same reference numerals are used.

The SAT-G-PLC unit 31 described in FIG. 7 is realized by the SAT-PLC function of the satellite communication control device 31 described in FIG. Further, the G-PLC unit 602 described in FIG. 7 is realized by the G-PLC function of the remote unit side panel control device 32 and the G-PLC 602 of the gate control device 6-n described in FIG.
In FIG. 7, the G-PLC unit 602 exemplifies a case where the G-PLC unit 602 is a G-PLC 602 arranged in the gate control device 6-n, but a remote monitoring control device that is a slave station having a SAT-PLC function. 3 may be arranged.
In FIG. 7, one slave station system 6 is shown, but a plurality of slave station systems 6 are arranged. The other slave station systems 6 are not shown. It is assumed that the same processing is performed in each slave station system 6.

  First, the control station system 1 acquires the J-ALERT transmitted via the communication satellite from the fire department 100 exemplified as a predetermined government office, and the control station system 1 that receives the J-ALERT sends a simultaneous closing signal, The SAT-G-PLC unit 31 of the slave station system 3 and the control station system 2 that manages the slave station system 3 that has transmitted the simultaneous closing signal are transmitted. The control center system 2 that has acquired the simultaneous closing signal displays information on the slave station system 3 to which the simultaneous closing signal has been transmitted and information on the gates (water gates / land ridges) closed by the simultaneous closing signal on the touch monitor 232 or the like. Good.

The SAT-G-PLC unit 31 of the slave station system 3 (slave station 1) that has received the broadcast notification command sends a simultaneous broadcast based on the broadcast notification command to the G-PLC unit 602 of the slave station system 6 (slave station n). A notification instruction is transmitted.
The G-PLC unit 602 starts a timer for determining whether or not a predetermined time has elapsed after transmitting a control signal for starting the information providing facility managed by the slave station system 6.
When the G-PLC unit 602 determines that a predetermined time has elapsed, the G-PLC unit 602 transmits a control instruction to close the gate (sluice or land anchor) to be closed to each gate.

The slave station system 3 in which the SAT-G-PLC unit 31 in FIG. 7 is arranged is arranged at a remote location and connected by an optical cable or the like to the slave station system 6 in which the G-PLC unit 602 is arranged. . Therefore, there is a possibility that the SAT-G-PLC unit 31 and the G-PLC unit 602 may be unable to communicate due to damage to the optical cable in the event of a disaster.
In FIG. 7, the G-PLC unit 602, which is a gate operation device, acquires a simultaneous notification instruction from the SAT-G-PLC unit 31 as warning information based on emergency information transmitted via a communication satellite, and performs a simultaneous notification instruction. On the basis of the control signal for starting the information providing equipment, determining whether or not a predetermined time has passed since transmitting the control signal for starting the information providing equipment, For example, satellite communication between the control station system 1 and the slave station system 3 or the slave station system 3 and the slave station system by transmitting a control instruction for closing the gate to each gate when a predetermined time has elapsed. Even when trouble such as inability to communicate occurs in optical communication with 6, the SAT-G-PLC unit 31 can control the gate while ensuring the retreat time.

Next, the third automatic gate operation process will be described with reference to FIG. FIG. 8 is a sequence diagram illustrating an example of a third automatic gate operation process according to the embodiment.
In FIG. 8, in the third automatic gate operation process, the control station system 1 transmits a simultaneous notification command to the SAT-G-PLC unit 31 of the slave station system 3 based on J-ALERT, and transmits the simultaneous notification command. A case where a closing instruction for closing the gate is transmitted to the slave station system 31 when a predetermined time has elapsed since then.

The function of the control station system 1 described in FIG. 8 can be realized by the central simultaneous command monitoring device 115 described in FIG.
Although one control station system 1 is shown in FIG. 8, a plurality of control station systems 1 may be arranged. When a plurality of control station systems 1 are arranged, the communication path can be duplicated in receiving J-ALERT and transmitting / receiving with the slave station system 3 and the control station system 2. 2 and the whole system of the slave station system 3 can be improved in availability.

  First, the control station system 1 acquires a J-ALERT transmitted from a fire department 100 exemplified as a predetermined government office via a communication satellite. The control station system 1 that has acquired the J-ALERT sends a simultaneous notification command to the control station system 2 that manages the SAT-G-PLC unit 31 of the slave station system 3 and the slave station system 3 that has transmitted the simultaneous notification command. Send. In addition, the process which transmits simultaneous alerting | reporting instruction | command is the same as the process demonstrated in FIG.

The control center system 2 that has acquired the simultaneous notification command may display information on the slave station system 3 to which the simultaneous notification command has been transmitted and information on the gates (water gates / landers) that are closed by the simultaneous closure command on the touch monitor 232. The points are the same as in FIG.
The SAT-G-PLC unit 31 of the slave station system 3 that has acquired the simultaneous notification command transmits a control signal for starting the information providing facility. When the information providing facility is activated, it is notified to the vicinity of the gate that the gate is closed.

The control station system 1 starts a timer for determining whether or not a predetermined time has elapsed after transmitting the simultaneous notification command to the SAT-G-PLC unit 31 of the slave station system 3. The process for determining whether or not a predetermined time has elapsed using the countdown by the timer is the same as the process described in FIG.
When the control station system 1 determines that a predetermined time has elapsed, the control station system 1 transmits a control command for closing the gate (sluice gate or land anchor) to be closed to the SAT-G-PLC unit 31. The SAT-G-PLC unit 31 transmits a control instruction to close the gate (sluice gate or land anchor) to be closed to each gate.

  In FIG. 8, the control station system 1 which is a gate operating device acquires J-ALERT information as warning information based on emergency information transmitted via a communication satellite, and provides information based on the J-ALERT information. A simultaneous notification command for starting the equipment is transmitted to the slave station system 3, and it is determined whether or not a predetermined time has passed since the transmission of the simultaneous notification command to determine whether or not a predetermined time has passed. When the time elapses, a control command for closing the gate is transmitted to the slave station system 3, so that the evacuation time can be secured and the gate can be controlled.

  In addition, the 1st automatic gate operation process-3rd automatic gate operation process demonstrated in FIGS. 6-8 can each be used individually, or can be used in combination. For example, in the third automatic gate operation process, the control station system 1 determines that a predetermined time has elapsed and transmits a control command for closing the gate to the slave station system 3. When a control command is not transmitted from 1 to the slave station system 3, the slave station system 3 sends a control instruction to the gate to be closed (water gate or land anchor) to each gate by the first automatic gate operation processing. You may send it. Similarly, when the G-PLC 602 of the slave station system 6 cannot obtain a control instruction by the third automatic gate operation process or the first automatic gate operation process, the slave station system 6 performs the second automatic gate operation process. The G-PLC 602 may transmit a control instruction for closing the gate to each gate. That is, in this embodiment, when information is transmitted from the upstream control station system 1 to the SAT-G-PLC unit 31 and further to the G-PLC unit 602 on the downstream side, information is transmitted from the upstream side. Even when it is not performed for some reason, the gate can be automatically controlled on the downstream side.

  Next, device information collection processing will be described with reference to FIG. FIG. 9 is a sequence diagram illustrating an example of a device information collection process according to the embodiment.

  In FIG. 9, the G-PLC 602 of the slave station system 6 includes information on the water level measured by the water level meter, audio information collected by the sound collection microphone, video information taken by the TV camera, open / closed state and open / closed installed at the gate. Collect device information such as sensor information to detect obstacles. The device information may include information on a failure of a device such as a gate. The G-PLC 602 transmits the collected device information to the SAT-G-PLC unit 31 of the slave station system 3. The SAT-G-PLC unit 31 determines whether to transmit the collected device information to the control station system 1. For example, it is determined whether or not a transmission condition determined in advance in the collected device information is satisfied. The transmission conditions include, for example, a time zone in which device information is collected, a transmission timing at which device information is transmitted (for example, when the collected device information is transmitted by batch processing every predetermined time), a type of failure information to be transmitted, and the like. .

The control station system 1 that has acquired the device information from the SAT-G-PLC unit 31 performs a display process for displaying the acquired device information. The device information can be displayed, for example, on the monitor 127 of the monitoring terminal control device 126 described with reference to FIG.
The control station system 1 transmits the acquired device information to the control center system 2.
The control center system 2 that has acquired the device information from the control station system 1 performs a display process for displaying the acquired device information. The device information can be displayed, for example, on the monitor 223 of the monitoring terminal control device 222 described with reference to FIG.

In the present embodiment, since device information such as device failure and gate status can be collected, the gate can be controlled from a remote place safely and reliably. For example, when an instruction to automatically close the gate is transmitted in the automatic gate operation process described in FIGS. 6 to 8, confirmation of the gate that could not be closed automatically, the situation of the gate, the situation of the water level, etc. are controlled. It can be monitored in the station system 1 or the control station system 2. Also, the control station system 1 may be configured to exclude a predetermined gate from being subject to simultaneous closure depending on the situation of the gate (for example, a situation where a device that opens and closes the gate is out of order).
Based on the collected device information, the control station system 1 or the control center system 2 may execute processing for manually operating the gate.

Next, the first manual gate operation process will be described with reference to FIG. FIG. 10 is a sequence diagram illustrating an example of a first manual gate operation process according to the embodiment.
The first manual gate operation process is a process in which the gates to be closed are individually set in the control station system 1, and control commands such as closing are simultaneously transmitted to the gates set from the control station system 1.

In FIG. 10, the control station system 1 transmits simultaneously a closing instruction for closing the gates to be closed to the SAT-G-PLC unit 31 of the slave station system 3.
The SAT-G-PLC unit 31 that has received the closing command from the control station system 1 outputs a control instruction for closing each gate.
Further, the control station system 1 transmits information on the transmitted closing instruction to the control center system 2. The control center system 2 that has acquired the information on the closing instruction from the control station system 1 may display information on the gate to be closed.

  In this embodiment, the gate can be automatically closed based on emergency information and can also be operated manually. For example, when the gate is closed by opening and closing individually or by releasing the tsunami warning. In addition, manual operation is possible from the control station. In addition, you may make it operate a gate manually based on apparatus information demonstrated in FIG.

Next, the second manual gate operation process will be described with reference to FIG. FIG. 11 is a sequence diagram illustrating an example of a second manual gate operation process according to the embodiment.
The second manual gate operation process is a process in which the gates to be closed are individually set in the control center system 2 and instructions for closing and the like are simultaneously transmitted to the gates set from the control center system 2.

In FIG. 11, the control center system 2 transmits a closing instruction for closing the gate to be closed to the control station system 1. Based on the closing command acquired from the control center system 2, the control station system 1 transmits the closing command all at once to the SAT-G-PLC unit 31 of the slave station system 3 that manages the gate to be closed. By transmitting the closing command transmitted from the control station system 2 to the slave station system 3 via the control station system 1, the control station system 1 can centrally manage the status of the gate. Moreover, since it is not necessary to manage control of each gate in the control center system 2, the load of the control center system 2 can be reduced.
The SAT-G-PLC unit 31 that has received the closing command from the control station system 1 outputs a control instruction for closing each gate.
The control center system 2 may display information on the gate to be closed.

In the present embodiment, the gate can be automatically closed based on the emergency information and can be operated manually. For example, the gate once closed can be individually opened and closed. In addition, when the gate is opened by releasing the tsunami warning, manual operation is possible from the control station. In addition, you may make it operate a gate manually based on apparatus information demonstrated in FIG.
The control station system 2 has a limited area to be managed with respect to the control station system 1 and is often close to the slave station system 3 in terms of distance. Therefore, an administrator who manages the control station system 2 can easily deal with, for example, the slave station system 3 in which a problem has occurred, as compared with an administrator who manages the control station system 1. Since the gate can be manually operated from the control center system 2, it is possible to easily manage the gate for each region.
