Description

  Embodiments of the present invention relate to an alarm station and a discharge alarm alert transmission method.

  In the conventional discharge warning system, when the monitoring station determines the discharge of the dam by the water level rise of the dam at the time of rainy weather, etc., a control signal is transmitted from the monitoring station to the warning station. The alarm station, upon receiving the control signal, issues a discharge alert that warns with a siren or voice as a warning to the river area. Since the release alarm is issued often in rainy weather, the reception level of the radio wave may be reduced, and the control station may not receive the control signal. In this case, a discharge alarm is not issued at the alarm station.

  Therefore, conventionally, in the alarm station where the alarm vehicle is used to travel around the alarm station one by one using the alarm car and the discharge alarm is not reported, the operator directly operates the alarm device in the alarm station to issue the discharge alarm. It was However, in the alarm station, when a discharge alarm is issued not triggered by a control signal transmitted from the monitoring station, such as a discharge alarm issued in response to the direct operation of the alarm device, the recording of the discharge alert is monitored Not sent to the station. Therefore, when the discharge alarm alerting | reporting which does not make a control signal a trigger is performed by the alarm station, there existed a case where the monitoring station could not manage the alerting | reporting record of the discharge alert.

  FIG. 4 is a sequence diagram showing a process flow of the discharge alarm system 100 in the first embodiment. In FIG. 4, the case where the discharge alarm system 100 includes one monitoring station 10, one relay station 20, and two alarm stations 30 (alarm station 30-1 and alarm station 30-2) An example will be described. Further, since the alarm station 30-2 is located at a geographically distant place from the monitoring station 10, the alarm station 30-2 is connected to the monitoring station 10 via the relay station 20.

  The monitoring station 10 transmits a discharge alarm control signal to the alarm station 30-1 and the relay station 20 (step S101). The alarm station 30-1 receives the discharge alarm control signal transmitted from the monitoring station 10. The alarm station 30-1 issues a discharge alarm in response to the discharge alarm control signal (step S102). The alarm station 30-1 stores the operation of the alarm performed by the alarm station 30-1 in the alarm recording unit 329 of the alarm station 30-1 after the alarm of the discharge alarm (step S103). Thereafter, the alarm station 30-1 transmits an alert including the information of the alerting operation stored in the alert recording unit 329 to the monitoring station 10 (step S104).

  The relay station 20 receives the discharge alarm control signal transmitted from the monitoring station 10. The relay station 20 transmits the received discharge alarm control signal to the alarm station 30-2. However, in preparation for the discharge alarm control signal transmitted from relay station 20 not reaching alarm station 30-2 due to the influence of rain or the like, relay station 20 can not receive, etc. 30 and patrol the alarm station 30 for which the discharge alarm has not been reported. Here, when it is confirmed that the alarm station 30-2 is a discharge alarm unreported notification (step S105), the operator walks to the alarm station 30. Thereafter, the operator operates the test unit 319 of the alarm device 31 in the alarm station 30 to issue a discharge alarm (step S106).

  The basic control unit 311 controls the alarm notification unit to issue a discharge alarm (step S107). The basic control unit 311 stores the operation of the alarm performed by the alarm station 30-2 in the alarm recording unit 329 of the alarm station 30-2 (step S108). Thereafter, the basic control unit 311 stands by until a predetermined condition is satisfied (step S109). The predetermined condition is a condition for transmitting the information of the alarm operation stored in the alarm recording unit 329. For example, the inspection signal transmitted from the monitoring station 10 is received. The inspection signal is a signal including an inspection instruction transmitted from the monitoring station 10 to each alarm station 30 periodically (for example, at a preset time).

When the inspection signal transmitted from the monitoring station 10 is received, the basic control unit 311 determines that the predetermined condition is satisfied.
On the other hand, the basic control unit 311 determines that the predetermined condition is not satisfied when one or both of the cases where the inspection signal transmitted from the monitoring station 10 is not received are satisfied.

When a predetermined condition is satisfied, the basic control unit 311 generates an alert record including information on the alert operation stored in the alert recording unit 329. Note that the basic control unit 311 may collectively generate information on an alarm operation stored in the alarm recording unit 329 and may generate an alarm record for each control. The basic control unit 311 controls the communication unit 330 to transmit the generated alert record to the monitoring station 10 (step S110).
The relay station 20 receives the report record transmitted from the alarm station 30-2, and transmits the received report record to the monitoring station 10.

The basic control unit 311 sets a value obtained by subtracting 1 from the number of transmissions N as a new N (step S111). The value of the number of transmissions N is set in advance. The number of transmissions N is, for example, three. The basic control unit 311 determines whether N = 0 (step S112). If N = 0 (step S112-YES), the alarm station 30-2 ends the process.
On the other hand, when N is not 0 (step S112-NO), the alarm station 30-2 repeatedly executes the process of step S110 to step S112.

  The monitoring station 10 determines whether or not the alert record transmitted from the alarm station 30-1 or the alarm station 30-2 has been received (step S113). When the report record can not be received (step S113-NO), the monitoring station 10 requests the alarm station 30 which can not receive the report record to retransmit (step S114). For example, when the monitoring station 10 transmits an inspection signal to the alarm station 30, an alert record is included as a response to the inspection signal. However, even though the inspection signal is transmitted, if the response to the inspection signal can not be received, the monitoring station 10 requests retransmission. Here, it is assumed that the monitoring station 10 can not receive an alert record from the alarm station 30-2. In this case, the monitoring station 10 requests the alarm station 30-2 to retransmit the notification record.

The relay station 20 relays the retransmission request transmitted from the monitoring station 10 to the alarm station 30-2. The alarm station 30-2 receives the retransmission request transmitted from the relay station 20. The basic control unit 311 resends the reporting record to the monitoring station 10 via the relay station 20 in response to the resend request (step S115). The monitoring station 10 stores the alert record retransmitted from the monitoring station 10 (step S116).
If the alarm record can be received in the process of step S113 (YES in step S113), the monitoring station 10 stores the alarm record (step S116).

  According to the alarm station 30 configured as described above, it is possible to manage the alarm recording of the discharge alarm when the alarm signal is issued at the alarm station 30 not triggered by the control signal. Specifically, even when the test unit is directly operated by the operator, the alarm station 30 records the operation of the discharge alarm and later transmits it as the alarm record to the monitoring station 10. As a result, the monitoring station 10 can obtain an alarm record. As a result, it is possible to manage the reporting of the discharge alarm when the discharge station does not trigger the control signal at the alarm station 30.

  Further, the alarm station 30 transmits the alarm record to the monitoring station 10 multiple times. Thereby, in the monitoring station 10, it is possible to raise the probability of acquiring the alert record. Therefore, it is possible to more reliably manage the reporting of the discharge alarm when the discharge alarm is not triggered by the control signal at the alarm station 30.

The alarm station 30 in the second embodiment is different from the alarm station 30 in the first embodiment in that the external operation unit 44 and the external control unit 331 in the alarm device 31 are newly provided. The differences will be described below.

The external operation unit 44 is an operation unit that receives an instruction of the operator on the alarm device 31. For example, the external operation unit 44 receives an instruction of notification of a discharge alarm from the operator.
The external control unit 331 is an interface for inputting an instruction from the external operation unit 44 to the alarm device 31. The external control unit 331 causes the basic control unit 311 to output a discharge alert instruction of the discharge alert input through the external operation unit 44, thereby causing the discharge alert to be issued.

  FIG. 8 is a sequence diagram showing a process flow of the discharge alarm system 100 in the second embodiment. In FIG. 8, the case where the discharge alarm system 100 includes one monitoring station 10, one relay station 20, and two alarm stations 30 (alarm station 30-1 and alarm station 30-2) An example will be described.

Thereafter, the operator operates the external operation unit 44 provided outside the alarm station 30 to issue a discharge alarm (step S201).

  According to the alarm station 30 configured as described above, there is no need for an operator to enter the alarm station 30. Thus, even if the outside is raining, the devices in the alarm station 30 are not exposed to the rain. Therefore, the deterioration of the device is suppressed. In addition, complicated operations in the alarm station 30 are not necessary. This makes it possible to simplify the operation procedure until the release alert is issued.
