Description

  Embodiments described herein relate generally to a microwave multiplex radio apparatus and a power saving control method.

  In recent years, there has been known a microwave multiplex radio apparatus that wirelessly transmits / receives (communications) a signal in which a plurality of pieces of information are multiplexed using a microwave band radio wave.

  In this microwave multiplex radio apparatus, the main part of the functions of the microwave multiplex radio apparatus has, for example, a duplex configuration of No. 1 machine and No. 2 machine (active system and standby system). Thereby, for example, even if one of the first and second machines (active system) fails, it can be continuously operated in the standby system.

  Note that the microwave multiplex radio equipment has a hot standby system in which the power is always turned on (ON) for both Unit 1 and Unit 2 so that the operation can be instantaneously switched to the standby system in the event of a failure in the active system. I'm taking it. In other words, in the microwave multiplex radio apparatus, for example, even when Unit 1 is operating as an active system, the power supply for the Unit 2 side, which is a standby system, is also turned on and always consumes power for two systems. Yes.

  As described above, when the microwave multiplex radio apparatus has a duplex configuration of Unit 1 and Unit 2, during maintenance or maintenance, one of the units of the microwave multiplex radio apparatus (one of Unit 1 and Unit 2) is intentionally used. In some cases, the inspection work is performed with the power off.

  However, in the microwave multiplex radio apparatus, it is impossible to intentionally turn off (that is, turn off) the power of the first unit for the purpose of forcibly suppressing the amount of power in the station building, for example.

  For example, when the power of one unit is intentionally turned off for maintenance or other purposes (that is, outside the maintenance state), in the microwave multiplex radio device, the unit where the power was turned off has failed It is judged as.

  In other words, the microwave multiplex radio apparatus always has the first unit / 2 even when it is necessary to operate with a generator due to circumstances such as a power failure or when it is necessary to suppress power consumption as much as possible. Both units can be operated only with the power on, and power consumption cannot be reduced (cannot be operated with only one unit intentionally).

  Therefore, the problem to be solved by the present invention is to provide a microwave multiplex radio apparatus and a power saving control method capable of reducing power consumption.

  The microwave multiplex radio apparatus according to the embodiment includes a first unit that performs radio communication using a radio wave in a microwave band.

  Hereinafter, embodiments will be described with reference to the drawings.

  FIG. 1 is a block diagram showing a configuration of a microwave multiplex radio apparatus 10 according to the present embodiment. The microwave multiplex radio apparatus 10 according to the present embodiment has a function of wirelessly communicating a signal obtained by multiplexing a plurality of pieces of information using a microwave band radio wave.

  As shown in FIG. 1, the microwave multiplex radio apparatus 10 includes a monitoring control input / output terminal 11, a first unit 12, a first unit power source 13, a second unit 14, a second unit power 15 and a control unit 16. . Although not shown in FIG. 1, the microwave multiplex radio apparatus 10 is communicably connected to a monitoring control apparatus installed outside (remotely) the microwave multiplex radio apparatus 10. The monitoring control device has a function of monitoring the operation of the microwave multiplex radio apparatus 10.

  The monitoring control input / output terminal 11 has a function of inputting / outputting a signal to be wirelessly communicated. The monitoring control input / output terminal 11 inputs a signal (hereinafter referred to as a power saving setting signal) for setting a power saving mode for operating the microwave multiplex radio apparatus 10 with power saving from the monitoring control apparatus. Further, the monitoring control input / output terminal 11 inputs a signal (hereinafter referred to as a power saving cancellation signal) for canceling the power saving mode for operating the microwave multiplex radio apparatus 10 with power saving from the monitoring control apparatus. The monitoring control input / output terminal 11 outputs a signal indicating that the power saving mode is set in the microwave multiplex radio apparatus 10 to the monitoring control apparatus.

  Here, the microwave multiplex radio apparatus 10 includes a first machine (active system) that performs radio communication using a radio wave in the microwave band and a second machine that operates as a backup system of the first machine. In other words, the microwave multiplex radio apparatus 10 has a configuration in which main parts of the functions of the microwave multiplex radio apparatus 10 are duplicated.

  The first unit provided in the microwave multiplex radio apparatus 10 includes a first unit 12. The first unit 12 multiplexes information to be wirelessly communicated, for example, information from a terminal connected to the microwave multiplex radio apparatus 10, and modulates it to a signal that can be transmitted wirelessly. The signal modulated by the first unit 12 is output via the waveguide output unit. Unit 1 unit 12 demodulates the signal input via the waveguide input unit. As described above, the first unit 12 has a function of executing signal processing for performing wireless communication using microwave waves.

  The first unit-side power supply 13 supplies power to the first unit (the first unit 12 included in the first unit) included in the microwave multiplex radio apparatus 10. Further, the first unit-side power supply 13 supplies power to the control unit 16.

  Note that the first unit (unit 1 unit 12) described above operates in conjunction with the first unit side power supply 13.

  On the other hand, the second machine included in the microwave multiplex radio apparatus 10 includes a second machine unit 14. The No. 2 unit 14 operates as a spare system of the No. 1 unit, for example, and has the same function as the No. 1 unit 12 described above.

  The No. 2 side power supply 15 supplies electric power to No. 2 machine (the No. 2 unit 14 included therein) included in the microwave multiplex radio apparatus 10. The second machine power supply 13 supplies power to the control unit 16.

  It is assumed that the second machine (second machine unit 14) operates in conjunction with the second machine side power supply 15.

  The control unit 16 has a function of controlling the operation of the microwave multiplex radio apparatus 10. The control unit 16 operates in common with the first and second machines included in the microwave multiplex radio apparatus 10 described above.

  The control unit 16 includes an operation panel for performing operations on the microwave multiplex radio apparatus 10. The operation panel is provided, for example, on the front surface of the microwave multiplex radio apparatus 10. Further, the operation panel is provided with a switch (hereinafter referred to as a power saving setting switch) for setting a power saving mode for operating the microwave multiplex radio apparatus 10 with power saving.

  When the power saving setting switch is turned on (ON) by, for example, maintenance personnel, the control unit 16 sets the power saving mode in the microwave multiplex radio apparatus 10. On the other hand, when the power saving setting switch is turned off by a maintenance staff or the like, the control unit 16 cancels the power saving mode in the microwave multiplex radio apparatus 10.

  When a power saving setting signal is input via the monitoring control input / output terminal 11, the control unit 16 sets the power saving mode in the microwave multiplex radio apparatus 10. On the other hand, when a power saving cancellation signal is input via the monitoring control input / output terminal 11, the control unit 16 cancels the power saving mode in the microwave multiplex radio apparatus 10.

  When the power saving mode is set in the microwave multiplex radio apparatus 10 as described above, the control unit 16 sends a signal indicating that the power saving mode is set in the microwave multiplex radio apparatus 10 to the monitoring control input. The data is output to the monitoring control device via the output terminal 11.

  Further, when the power saving mode is not set in the microwave multiplex radio apparatus 10 (hereinafter, referred to as a normal operation mode), the control unit 16 supplies power to the No. 1 side power supply 13 and the No. 2 side power supply 15. In other words, when the normal operation mode is set, the operation 1 can be instantaneously switched to the standby system (for example, No. 2) when a failure or the like occurs in the active system (for example, No. 1). Both the Unit-side power supply 13 and the Unit-2 power supply 15 are in a state of supplying power.

  On the other hand, when the power saving mode is set in the microwave multiplex radio apparatus 10, the control unit 16 turns off the No. 2 side power supply 15 that supplies power to the No. 2 machine that operates as a standby system. That is, while the power saving mode is set in the microwave multiplex radio apparatus 10, only the No. 1 unit power supply 13 is in a state of supplying power.

  Note that the microwave multiplex radio apparatus 10 according to the present embodiment has the unit-side power supply 15 that supplies power to the unit-2 operating as a standby system in a state where the normal operation mode is set, for example, when the unit-side power supply 15 is turned off The control unit 16 is configured to detect the occurrence of a failure of the second machine. Thus, when the occurrence of a failure in Unit 2 is detected, a signal indicating that the failure has occurred (hereinafter referred to as a failure occurrence signal) is output to the monitoring control device via the monitoring control input / output terminal 11. The

  Hereinafter, the operation of the microwave multiplex radio apparatus 10 according to the present embodiment will be described. The microwave multiplex radio apparatus 10 executes a power saving mode setting process and a power saving mode release process which will be described later.

  First, the processing procedure of the power saving mode setting process executed by the microwave multiplex radio apparatus 10 according to the present embodiment will be described with reference to the flowchart of FIG.

  Here, it is assumed that the microwave multiplex radio apparatus 10 is in a state where the power saving mode is not set, that is, in a state where the normal operation mode is set. In this case, the No. 1 side power source 13 and No. 2 side power source 15 of the microwave multiplex radio apparatus 10 supply power to No. 1 unit (No. 1 unit 12) and No. 2 unit (No. 2 unit 14), respectively, as described above. ing. In the following description, it is assumed that the first machine operates as an active system and the second machine operates as a backup system for the first machine.

  First, a power saving mode is set in the microwave multiplex radio apparatus 10 (step S1).

  Here, as a method of setting the power saving mode in the microwave multiplex radio apparatus 10 according to the present embodiment, a method using the power saving setting switch provided on the operation panel included in the control unit 16 and a setting from the monitoring control apparatus are used. There is a way to do it.

  The method using the power saving setting switch is used, for example, when a maintenance staff or the like is in the vicinity of the microwave multiplex radio apparatus 10 (that is, when an operation panel included in the control unit 16 can be operated). In this method using the power saving setting switch, when the power saving setting switch is turned on by a maintenance person or the like of the microwave multiplexing wireless device 10, the power saving mode is set in the microwave multiplexing wireless device 10.

  On the other hand, the method of setting from the monitoring control device is used, for example, when maintenance personnel or the like are not in the vicinity of the microwave multiplex radio apparatus 10 (that is, when the operation panel included in the control unit 16 cannot be operated). In the method of setting from the monitoring control device, a power saving setting signal for setting the power saving mode is transmitted from the monitoring control device in accordance with the operation of the administrator of the monitoring control device. The power saving setting signal is input to the microwave multiplex radio apparatus 10 via the monitoring control input / output terminal 11. Thus, when the power saving setting signal is input via the monitoring control input / output terminal 11, the power saving mode is set in the microwave multiplex radio apparatus 10.

  When the power saving mode is set as described above, the control unit 16 turns off the power of the second unit-side power supply 15 that supplies power to the second unit that operates as a standby system (step S2). Even in this case, since the first power source 13 supplies power to the first unit (the first unit 12 included in the first unit), the microwave multiplex radio apparatus 10 performs wireless communication by the first unit. Can do.

  Further, the control unit 16 outputs a signal indicating that the power saving mode is set (a signal during power saving setting) to the monitoring control device via the monitoring control input / output terminal 11 (step S3). Thus, when the power saving setting signal is output to the monitoring control apparatus, the monitoring control apparatus displays that the power saving mode is set in the microwave multiplex radio apparatus 10. Thereby, the maintenance person on the monitoring control apparatus side can easily confirm that the power saving mode is set in the microwave multiplex radio apparatus 10.

  As described above, when the Unit 2 side power supply 15 is turned off in the state where the normal operation mode is set, the occurrence of a failure is detected, but in the state where the power saving mode is set, The operating state of Unit 2 when the power is turned off is masked. That is, in a state where the power saving mode is set, no failure occurrence signal is output even when the Unit 2 side power supply 15 is turned off.

  Since the power saving mode is set as described above, the state in which the Unit 1 side power supply 13 and the Unit 2 side power supply 15 each supply power changes to the state in which only the Unit 1 side power supply 13 supplies power, The power consumption in the microwave multiplex radio apparatus 10 can be reduced to about half.

  Next, with reference to a flowchart of FIG. 3, a processing procedure of the power saving mode release process executed by the microwave multiplex radio apparatus 10 according to the present embodiment will be described.

  Here, it is assumed that the microwave multiplex radio apparatus 10 is in a state where the power saving mode is set by the power saving mode setting process described above. In this case, in the microwave multiplex radio apparatus 10, only the No. 1 unit power supply 13 supplies power.

  First, the power saving mode is canceled in the microwave multiplex radio apparatus 10 (step S11).

  Here, as a method of canceling the power saving mode in the microwave multiplex radio apparatus 10 according to the present embodiment, a method using a power saving setting switch provided on an operation panel included in the control unit 16 and a setting from the monitoring control apparatus are used. There is a way to do it.

  The method using the power saving setting switch can be used, for example, when a maintenance person or the like is in the vicinity of the microwave multiplex radio apparatus 10 (that is, when a maintenance person or the like can operate the operation panel included in the control unit 16). In this method using the power saving setting switch, when the power saving setting switch is turned off by a maintenance person or the like of the microwave multiplexing wireless device 10, the power saving mode is canceled in the microwave multiplexing wireless device 10.

  On the other hand, the method of setting from the supervisory controller is used when, for example, maintenance personnel are not in the vicinity of the microwave multiplex radio device 10 (that is, when maintenance personnel cannot operate the operation panel included in the control unit 16). Can do. In the method of setting from the monitoring control apparatus, a power saving cancellation signal for canceling the power saving mode is transmitted from the monitoring control apparatus in response to an operation of an administrator of the monitoring control apparatus. This power saving cancellation signal is input to the microwave multiplex radio apparatus 10 via the monitoring control input / output terminal 11. When the power saving cancellation signal is input through the monitoring control input / output terminal 11 as described above, the power saving mode is canceled in the microwave multiplex radio apparatus 10.

  When the power saving mode is canceled as described above, the control unit 16 turns on the No. 2 side power supply 15 that supplies electric power of No. 2 machine that operates as a standby system (step S12). As a result, the microwave multiplex radio apparatus 10 is in a state where power is supplied to both the first and second units. For example, even if a failure or the like occurs in the first unit, which is the active system, the standby system 2 It becomes possible to switch the operation to the unit instantly.

  Here, while the power saving mode is set, the power saving setting signal is output to the monitoring control device as described above. However, when the power saving mode is canceled, the power saving setting signal is output. Is not output to the supervisory controller. That is, when the power saving mode is canceled, the output of the signal during the power saving setting is canceled (step S13).

  In the state where the power saving mode is set as described above, no fault occurrence signal is output even when the Unit 2 side power supply 15 is turned off, but the case where the power saving mode is canceled (that is, When the power saving mode is not set), for example, when one of the No. 1 unit side power supply 13 and the No. 2 unit side power supply 15 is cut off, a failure occurrence signal is output to the monitoring control device. As described above, the failure occurrence signal is output via the monitoring control input / output terminal 11.

  As described above, when the power saving mode is canceled (that is, the normal operation mode is set), only the Unit 1 power source 13 supplies power, and the Unit 1 side power source 13 and Unit 2 side power source are supplied. Both of these transition to a state where both 15 supply power. As a result, for example, when a failure occurs in Unit 1 that is the active system, it is possible to operate the microwave multiplex radio apparatus 10 in a state in which Unit 2 that is the standby system can be instantaneously operated as the active system.

  As described above, in the present embodiment, the first unit (the first unit 12 included in the first unit) that performs wireless communication using microwave waves, the first unit side power supply 13 that supplies power to the first unit, A second unit (contained in the second unit 14 included) operating as a standby system for the first unit, and a second unit-side power source 15 for supplying power to the second unit, and operating the microwave multiplex radio apparatus 10 with low power consumption When the power saving mode is set, power is supplied to the No. 1 side power source 13 and No. 2 side power source when the power saving mode is not set, and when the power saving mode is set, the No. 2 side Since the power supply 15 is turned off, only the Unit 1 power supply 13 supplies power while the power saving mode is set, so both the Unit 1 power supply 13 and the Unit 2 power supply 15 supply power. Compared to the case It can be reduced to about half the power consumption of the microwave multiplex radio apparatus 10.

  In this embodiment, a power saving setting signal for setting the power saving mode is input from an external monitoring control device (that is, a contact input is performed remotely), and the power saving setting signal is input. If the microwave multiplex radio apparatus 10 is located at a mountain relay station or a disaster area and maintenance personnel cannot easily operate the operation panel, the power saving mode is set. The power saving mode can be set from the monitoring control device (that is, remotely).

  Further, in the present embodiment, when the power saving mode is set, the administrator of the monitoring control device or the like has a configuration that outputs a signal indicating that the power saving mode is set to the monitoring control device. Can easily recognize that the microwave multiplex radio apparatus 10 is operating in the power saving mode.

  In the present embodiment, the power saving setting switch for setting the power saving mode is provided, and the power saving mode is set when the power saving setting switch is turned on. The maintenance staff can easily set the power saving mode using the operation panel.

  Further, in the present embodiment, when the power saving mode is not set and the Unit 2 side power supply 15 is turned off, a failure occurrence signal indicating that a failure has occurred in the Unit 2 is sent to the monitoring control device. When the power supply of Unit 2 is turned off with the power saving mode set, a failure occurrence signal indicating that a failure has occurred in Unit 2 is not output to the monitoring and control unit. Even when the power is turned off, the failure occurrence signal can be prevented from being output when the power saving mode is set.

  In the present embodiment, it has been mainly described that the first unit provided in the microwave multiplex radio apparatus 10 is an active system and the second unit is a standby system. However, the first unit is a standby system and the second unit is It may be configured to operate as an active system.

  Further, in the present embodiment, the description has been made assuming that the Unit 2 side power supply 15 is turned off when the power saving mode is set. However, for example, when some failure occurs in the Unit 1, the first unit The 1st machine side power supply 13 which supplies electric power to may be cut off. That is, it is only necessary that only one of the No. 1 side power supply 13 and the No. 2 side power supply 15 supply power when the power saving mode is set.

Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment.
