  The present invention relates to a circuit control device, and more particularly to a technique for preventing the entire circuit control device from stopping when a power supply device fails.

  Some conventional circuit control devices are configured by units composed of a plurality of types of circuit boards, and one unit includes a plurality of circuit boards of the same type. In a communication device constituted by such a circuit control device, all circuit boards of the same type are used for communication processing under normal conditions, and if a circuit board breaks down, communication processing is performed only with other circuit boards of the same type. In many cases, a redundant configuration called an n-1 redundant configuration is used.

  Among the plurality of types of circuit boards, a power supply board that functions as a power supply device having a function of supplying power to other circuit boards is also included. The power supply device is usually composed of a plurality of power supply boards. Since the power supply board has a large volume and a large calorific value, a power supply board having a minimum power supply capacity is usually used to operate other circuit boards in the unit.

Patent Document 1 describes a technology related to a backup battery that is provided separately from the main power supply device and supplies power when the power supply of the main power supply device is stopped. In this technique, in order to suppress the voltage drop speed of the battery, the power consumption is reduced by stopping the power supply to the standby wireless device when the battery voltage drops.

  However, if a power supply device with the minimum power supply capability is used to operate the board in the unit as described above, the entire circuit control device will stop if the suppliable power decreases due to a failure of the power supply device. There was a problem that.

  On the other hand, even if the method of the above-mentioned Patent Document 1 is applied, when the power supply to the battery further decreases after the power supply to the standby system control device is stopped, the entire operation system circuit control device is stopped. End up.

  The present invention has been made to solve the above-mentioned problems, and one of its purposes is to prevent the entire circuit control device from stopping even if the suppliable power decreases due to a failure of the power supply device or the like. Another object is to provide a circuit control device.

  The circuit control device according to the present invention for solving the above-described problems is one of a plurality of state modes that operate by a power supply device and power supply from the power supply device and have different power consumption amounts. In a circuit control device comprising a plurality of circuit boards, suppliable power information indicating power that can be supplied to the plurality of circuit boards and a combination of state modes of the circuit boards are stored in association with each other. Supply power corresponding state mode storage means, supplyable power information acquisition means for acquiring supplyable power information indicating power that can be supplied by the power supply apparatus, and states stored in association with the acquired supplyable power information Circuit board state mode control means for controlling each of the circuit boards so as to be a combination of modes.

  According to the present invention, since each circuit board can be controlled so that the state mode of each circuit board becomes a combination according to the suppliable power, the entire circuit control device does not stop even if the suppliable power is reduced. Can be.

  In the circuit control device, the power supply device includes a plurality of power supply boards, and the suppliable power information is information indicating power supplied from a power supply board among the plurality of power supply boards. It's good.

  In this way, each circuit board is controlled so that the state mode of each circuit board becomes a combination according to the power that can be supplied except for the power supply board that cannot be used due to a failure among the plurality of power supply boards. be able to.

  Further, in the circuit control device, the operation state acquisition means for acquiring the operation state of each circuit board and the supply power corresponding state mode storage means corresponding to each supplyable power information based on the acquired operation state. It may further include state mode combination changing means for changing the combination of the state modes of the respective circuit boards to be added and stored.

  By doing so, the combination of the state modes can be changed so that power can be preferentially supplied to a circuit board that is operating normally.

Embodiment 1. FIG.
Embodiment 1 of the present invention will be described with reference to the drawings.

  FIG. 1 is a system configuration diagram of a communication apparatus 1 according to the present embodiment. As shown in the figure, the communication device 1 according to the present embodiment is configured by a circuit control device including at least one unit including a power supply device P and a plurality of communication function units. The In the present embodiment, in particular, the communication apparatus 1 is configured as a single unit and will be described as including a communication function unit A, a communication function unit B, and a communication function unit C as communication function units.

  Each communication function unit includes a plurality of communication boards that are the same type of circuit boards. This circuit board is different for each communication function unit, and each communication function unit performs different communication processing.

  More specifically, the communication function unit A is composed of four communication boards, a communication board A1, a communication board A2, a communication board A3, and a communication board A4, and the communication boards A1 to A4 have the same function. . The communication function unit B includes two communication boards, a communication board B1 and a communication board B2, and the communication board B1 and the communication board B2 have the same function. The communication function unit C includes two communication boards, a communication board C1 and a communication board C2, and the communication board C1 and the communication board C2 have the same function.

  On the other hand, the power supply device P is composed of three power supply boards, that is, a power supply board P1, a power supply board P2, and a power supply board P3, and each of the power supply boards P1 to P3 supplies power to each communication board. have. The power supply board is also a circuit board. The power supply capability of the power supply board P1 and the power supply board P2 is twice that of the power supply board P3.

  When each power supply board is operating normally and each communication board is not in a failure state or removed from the operation system by a predetermined operation described later, the communication function unit A and the communication function unit B All communication boards (communication board A1 to communication board A4, communication board B1, and communication board B2) constituting the communication processing (hereinafter referred to as actual communication processing) related to actual communication are performed. If any of the communication boards fails, the actual communication process is continued using only the communication boards that have not failed. As described above, the redundant configuration in which the actual communication processing is normally performed by all the communication boards, and when a certain communication board fails, only the failed communication board is removed from the active system and the actual communication processing is continued is n-1 redundancy. Called composition. On the other hand, in the communication function unit C, only the communication board C1 or the communication board C2 performs the actual communication process. And when the communication board which is performing the actual communication process fails, the other communication board takes over the actual communication process of the communication board which failed, and performs an actual communication process. In this way, normally, all communication boards do not perform actual communication processing, and when a communication board performing actual communication processing fails, a communication board that has not performed actual communication processing until then takes over. The redundant configuration for performing communication processing in is called an n + 1 redundant configuration.

  Each communication board operates in one of a plurality of state modes with different power consumption amounts. Specifically, in order of decreasing power consumption, the communication board is not powered on (state mode sa), only the power control unit in the communication board operates, and no power is supplied to the communication board (state mode sb). ) Among the blocks provided in the communication board corresponding to each of the more detailed processes of the communication process, a state in which power is not supplied to a block with a particularly large power consumption (state mode sc), The operation frequency of the included processor is lowered, and the processing capability is reduced to operate in any one of the state modes of the state (state mode sd) and the normal state (state mode sn).

  When a certain communication board is not used (when the redundant configuration is not used), the communication board that is not used shifts to a non-use mode different from any of the above state modes by a predetermined operation of the maintenance person or detection of a failure. The communication board in the non-use mode waits for a predetermined operation by the maintenance person to move to the use state, and when the predetermined operation is accepted, shifts to one of the above-described state modes.

  FIG. 2 is a functional block diagram illustrating functions of the communication device 1. In the figure, the power supply board P1 and the communication board A1 are representatively described, but the same applies to other power supply boards and communication boards.

  As shown in the figure, the power supply substrate P1 functionally includes a power supply unit 10, an operation monitoring unit 12, a power supply abnormality detection unit 14, a substrate operation detection unit 16, a substrate control unit 18, and a storage unit 20. Is done. The communication board A1 is functionally configured to include a power supply control unit 50, a board interior 52, and an operation monitoring unit 54.

  First, functional blocks of the power supply substrate P1 will be described. The power supply unit 10 is connected to a commercial power supply and receives AC power supplied from a power plant. And electric power is supplied by distributing the input electric power with respect to each communication board as needed. Each power supply board and each communication board are connected in parallel or in series, for example.

  The operation monitoring unit 12 periodically monitors whether or not the power supply function of the power supply substrate P1 is operating normally. When operating normally, a self-power Alive signal indicating that the power supply function of the power supply board P1 is operating normally is periodically transmitted to the other power supply boards.

  The power supply abnormality sensing unit 14 receives the own power supply Alive signal transmitted from each power supply board other than the power supply board P1 as the other power supply Alive signal. Then, the reception status of the signal is notified to the board control unit 18. Specifically, the normal operation power supply board information indicating the power supply board that has transmitted the own power supply Alive signal received as the other power supply Alive signal is output to the board control unit 18.

  The board motion sensing unit 16 receives its own board Alive signal transmitted from each communication board by a process described later. The own board Alive signal is a signal indicating that the communication board that has transmitted the signal is operating normally. Then, the reception status of the signal is notified to the board control unit 18. Specifically, the normal operation communication board information indicating the communication board from which the own board Alive signal is received is output to the board controller 18.

  The storage unit 20 stores the board configuration of the communication device 1. That is, a substrate ID is assigned to each substrate and stored. Moreover, the state mode table which matched the power supply information which shows the electric power which the power supply device P can supply, and the combination of the state mode of each communication board is memorize | stored. In addition, the combination of power supply boards is specifically memorized as suppliable power information.

  An example of the state mode table stored in the storage unit 20 is shown in FIG. As shown in the figure, in the state mode table, combinations of state modes of the communication boards of the communication function units are stored in association with the suppliable power information.

  The suppliable power information takes one of states SA to SD and SN. That is, since the power that can be supplied differs depending on the combination of the power supply boards, the combination of the power supply boards that can supply power is stored as the supplyable power information. In the drawing, the state SA indicates a case where the power supply board P3 is abnormal, that is, the power supply is not possible, and the power supply board P1 and the power supply board P2 are normal, that is, the power supply is possible. The state SB indicates a case where one of the power supply board P1 or the power supply board P2 is abnormal and the other of the power supply board P1 or the power supply board P2 and the power supply board P3 are normal. The state SC indicates a case where the power supply substrate P3 is abnormal, one of the power supply substrate P1 or the power supply substrate P2 is abnormal, and the other of the power supply substrate P1 or the power supply substrate P2 is normal. Further, the state SD indicates a case where the power supply board P1 and the power supply board P2 are abnormal and the power supply board P3 is normal. In the states SA to SD, the power that can be supplied decreases in this order. Note that the state SN indicates a case where all the power supply boards are in a power supply enabled state, and the supplyable power is still larger than that in the state SA.

  The combination of the state modes of the communication boards of each communication function unit is such that the state mode of each communication board included in each communication function unit is any of the above-described state mode sa to state mode sd, state mode sn, or non-use mode. It is indicated by whether there is. In the figure, the communication board in any of the state mode sa to the state mode sd is described, and the board in the state mode sn or the non-use mode is omitted.

  Returning to the description of FIG. The board control unit 18 determines whether or not the power supply board indicated by each board ID stored in the storage unit 20 is operating normally based on the normal operation power supply board information transmitted from the power supply abnormality sensing unit 14. To do. Then, based on the combination of the power supply boards that operate normally, it is determined whether the power supply possible information is the state SA to the state SD or the state SN.

  The board control unit 18 controls each communication board so as to be in the state mode stored in the state mode table in association with the determined power supply availability information. Specifically, the state mode of each communication board is determined based on the state mode stored in the state mode table in association with the determined power supply availability information, and a sleep signal including information indicating the determined state mode is generated. Generate and transmit to each communication board.

  By receiving the Sleep signal transmitted in this way, each communication board changes its state mode to the state mode shown in FIG. 4 or FIG. 5, for example. In these figures, the communication board with a diagonal line is the board in the state mode sa. In FIG. 4, the power supply board P <b> 1 is in a power supply disabled state. This corresponds to the state SB of the state mode table, and the board control unit 18 transmits a Sleep signal to the communication board A4, the communication board B2, and the communication board C2 so as to be in the state mode sa. In FIG. 5, the power supply substrate P1 and the power supply substrate P3 are in a state where power supply is not possible. This corresponds to the state SC of the state mode table, and the board control unit 18 transmits a Sleep signal to the communication board A3, the communication board A4, the communication board B2, and the communication board C2 so as to be in the state mode sa.

  The board control unit 18 also receives normal operation communication board information transmitted from the board movement sensing unit 16 and determines whether or not the communication board indicated by each board ID stored in the storage unit 20 is operating normally. to decide. In addition, the state which is not operating normally here is not the state which is not operating at all, but the state which cannot be said to be operating normally all because the communication board has reached some predetermined state.

  When there is a communication board that is determined not to operate normally, the board control unit 18 rewrites the state mode table stored in the storage unit 20 so as to reduce the power consumption of the communication board. That is, the board control unit 18 acquires the operation state of each communication board by determining whether each communication board is operating normally, and each communication board corresponding to the suppliable power information based on the acquired operation state. The state mode combination has been changed.

  A specific example of this is shown in FIG. FIG. 6 is an example of the state mode table rewritten when it is determined that the communication board A2, the communication board B1, and the communication board C1 are not operating normally. In the state mode table shown in FIG. 3, the priority order of the communication boards that does not reduce the amount of power consumption even when the suppliable power decreases in each communication function unit, communication board A1, communication board A2, communication in communication function part A In the state mode table shown in FIG. 6, the order is communication board A1, communication board A3, communication board A4, and communication board A2. That is, by changing the combination of the state modes of each communication board corresponding to the suppliable power information by lowering the priority order of the communication boards determined to be not operating normally, the communication operating normally Electric power can be supplied preferentially to the board. Similarly, for communication function unit B and communication function unit C, the priority order of communication boards not operating normally is lowered to the lowest order.

  The communication board state mode control process by the board controller 18 is performed on each power supply board. Priorities are assigned in advance to the communication board state mode control processing performed by the board controller 18 of each power board. For example, the sleep signal by the process of the power board P1 and the sleep signal by the process of the power board P2 are described below. When the signal is received by the control unit 50, the power supply control unit 50 preferentially uses the sleep signal generated by the processing of one power supply board and discards the other.

  Next, functional blocks of the communication board A1 will be described. The board interior 52 is configured to include blocks provided corresponding to the processes performed in the communication board A1. Then, predetermined processing is performed in each block. More specifically, each block is connected to another communication board or the outside via a communication line as necessary, and performs a process of performing a predetermined process on an input signal and outputting the signal.

  The operation monitoring unit 54 periodically monitors whether the communication board A1 is functioning normally by monitoring the operation state of the board interior 52. If it is functioning normally, a self-board Alive signal indicating that it is functioning normally is periodically sent to the substrate motion sensing unit 16 of each power supply substrate (power supply substrate P1 to power supply substrate P3). Send.

  The power supply control unit 50 distributes and outputs the power input from the power supply unit 10 to the board interior 52, thereby supplying power necessary for the operation of the communication board A1. In addition, a Sleep signal transmitted from each power supply board is received, and the power supply state to the board interior 52 is controlled as necessary. Specifically, the power supply state to the substrate interior 52 is controlled so that the state mode instructed by the Sleep signal is set. When instructed to enter the state mode sa, the power supplied from the power supply device P to itself is cut off. When instructed to enter the state mode sc, the power supply for the blocks stored in advance among the blocks included in the substrate interior 52 is stopped. Further, when instructed to enter the state mode sd, the operating frequency of the processor, which is one of the hardware that realizes the function of the communication board A1, is lowered, and the processing capability is lowered to enter the power saving mode.

  When the sleep signals are received from a plurality of power supply boards, the sleep signal to be adopted is determined according to the predetermined priority order of the power supply boards, and the state mode indicated by the adopted sleep signal is entered into the board interior 52. Controls the power supply state of.

  As described above, by controlling the state mode of each communication board so as to be a combination of the state modes stored in advance, the amount of power consumption can be gradually reduced in accordance with the decrease in suppliable power. Therefore, even when the suppliable power decreases due to a failure of the power supply device P or the like, it is possible to prevent the entire communication device 1 from stopping.

  The above process will be described in more detail with reference to the flow of the communication board state mode control process in the board controller 18.

  FIG. 7 is a flowchart of the communication board state mode control process in the board controller 18. The processing shown in this flowchart is periodically performed in the substrate controller 18. As shown in the figure, the substrate controller 18 first receives various information necessary for processing. Specifically, normal operation power supply board information indicating the state of each power supply board and normal operation communication board information indicating the state of each communication board are received, and the operation state of each board is grasped (S100).

  Next, it is determined whether or not an abnormality has occurred in the communication board (S102). If there is an abnormality, the status mode table is set so as to lower the priority of power supply to the communication board in which the abnormality has occurred. The setting is changed (S104).

  Next, whether or not an abnormality has occurred in the power supply device P (the power supply function is not operating normally) is determined by whether or not there is a power supply board that is determined to be abnormal (S106). If no abnormality has occurred, the process is terminated. This process corresponds to the case where the suppliable power information is the state SN. On the other hand, when it is determined that an abnormality has occurred in the power supply device P, it is first determined whether or not the suppliable power information indicating the power supply state of the power supply device P is in the state SA (S108). Similarly, it is determined whether or not the state is SB or the state SC (S110, S112). Then, if it is determined that the state is SA, the state mode of each communication board is controlled so that the state mode stored in association with the state SA is obtained. Similarly, the state mode of each communication board is controlled so that the state mode is stored in association with the state SB if it is determined that the state is not the state SA but the state SB. If it is determined that the state is not the state SA or the state SB but the state SC, the state mode of each communication board is controlled so that the state mode is stored in association with the state SC. If it is determined that the state is not the state SC, the state mode of each communication board is controlled so that the state mode is stored in association with the state SD. As described above, the board controller 18 controls the state mode of each communication board.

  The transition of the state of each substrate will be described in more detail. FIG. 8 is a state transition diagram illustrating state transition of the communication device. In the figure, for the sake of simplicity, a communication apparatus provided with only the communication function section A, the communication function section B, and the power supply apparatus P will be described as an example. The communication function unit A, the communication function unit B, and the power supply device P each include two substrates.

  First, in state 70, each board has no failure and the communication apparatus performs normal operation. In this case, each board has an n-1 redundant configuration. When one of the boards included in the communication function unit A fails in the state 70, the communication apparatus transits to the state 71. At this time, the substrate control unit 18 performs a process of rewriting the state mode table as necessary.

  If another one of the boards included in the communication function unit A fails from the state 71, the communication function unit A stops functioning, and the communication apparatus transitions to the failure state 76. In the failure state 76, the communication device cannot perform communication processing. On the other hand, when one of the boards included in the communication function unit B further fails from the state 71, the communication apparatus transitions to the state 74. Also at this time, the substrate controller 18 performs a process of rewriting the state mode table as necessary. Further, when one of the boards included in the power supply device P further fails from the state 71, the communication device transits to the state 73. At this time, the substrate control unit 18 performs processing for controlling the state mode of the substrate included in each communication function unit based on the state mode table as necessary.

  In the state 74, when another one of the boards included in the communication function unit A or the communication function unit B fails, the communication device transits to the failure state 76. In the state 74, when one of the boards included in the power supply device P further fails, the communication device transits to the state 75. At this time, the substrate control unit 18 performs processing for controlling the state mode of the substrate included in each communication function unit based on the state mode table as necessary. If any one of the boards further fails from state 75, the communication apparatus transitions to failure state 76.

  Next, when one of the boards included in the power supply device P fails in the state 70, the communication device transits to the state 72. At this time, the substrate control unit 18 performs processing for controlling the state mode of the substrate included in each communication function unit based on the state mode table as necessary. In the state 72, when another one of the boards included in the power supply device P fails, the power supply device P stops functioning, and the communication device transits to the failure state 76.

  If another one of the boards included in the communication function unit A further fails from the state 72, the communication apparatus transitions to the state 73. At this time, the substrate control unit 18 performs a process of rewriting the state mode table as necessary. In the state 73, when one of the boards included in the communication function unit B further fails, the communication apparatus transits to the state 75. Also at this time, the substrate controller 18 performs a process of rewriting the state mode table as necessary. On the other hand, when another one of the boards included in the communication function unit A fails in the state 73, the communication apparatus transitions to the failure state 76.

  As described above, in the communication device 1, the substrate control unit 18 detects that the state of each substrate has changed, and performs processing according to the change.

  In the example of the state mode table shown in FIGS. 3 and 6, the state mode sb and the state mode sc are not used, but it is of course desirable to control the power consumption more finely by using these. It is. In addition, the power supply state of each power supply board may be determined by measuring the power that can be supplied instead of the two normal / abnormal states, thereby subdividing the power supply information and finely controlling the power consumption.

Embodiment 2. FIG.
Embodiment 2 of the present invention will be described with reference to the drawings.

  In the second embodiment, the system configuration of the communication device 2 is basically the same as that of the communication device 1 shown in FIG. 1, but includes a control function unit D instead of the communication function unit C. The control function unit D includes a plurality of control boards that are the same type of circuit boards. More specifically, the control function unit D is composed of two control boards, a control board D1 and a control board D2, and each control board has the same function.

  FIG. 9 is a functional block diagram illustrating functions of the communication device 2. In the figure, the power supply board P1, the control board D1, and the communication board A1 are representatively described, but the same applies to other power supply boards, control boards, and communication boards.

  As shown in the figure, in the present embodiment, the power supply abnormality sensing unit 14, the substrate operation sensing unit 16, the substrate control unit 18, and the storage unit 20 are moved from the power supply board P1 to the control board D1, respectively. 14a, substrate motion sensing unit 16a, substrate control unit 18a, and storage unit 20 are included in the control board D1. In addition to these, the control board D1 includes a power control unit 50, a board interior 52, and an operation monitoring unit 54. The functional block configuration of the communication board A1 is the same as that of the first embodiment.

  The power supply abnormality sensing unit 14a receives the self power supply Alive signal transmitted from each power supply board as a power supply Alive signal. Then, the reception status of the signal is notified to the board controller 18a. Specifically, the normal operation power supply board information indicating the power supply board from which the self power supply Alive signal is received is output to the board control unit 18a.

  The board motion sensing unit 16a receives its own board Alive signal transmitted from each control board other than each communication board and the control board D1. Then, the reception status of the signal is notified to the board controller 18a. Specifically, the normal operation communication board information indicating the communication board from which the own board Alive signal is received is output to the board controller 18a.

  The board control unit 18a determines whether or not the power supply board indicated by each board ID stored in the storage unit 20 is operating normally based on the normal operation power supply board information transmitted from the power supply abnormality sensing unit 14a. To do. Then, based on the combination of the power supply boards that operate normally, it is determined whether the power supply possible information is the state SA to the state SD or the state SN.

  The board controller 18a controls the control boards other than the communication boards and the control board D1 so as to be in the state mode stored in the state mode table in association with the determined power supply availability information. Specifically, the state mode of each control board other than each communication board and control board D1 is determined based on the state mode stored in the state mode table in association with the determined power supply availability information, and the determined state Information indicating the mode is included in a sleep signal to each control board other than each communication board and control board D1, and is transmitted to each board.

  The board control unit 18a also receives normal operation communication board information transmitted from the board motion sensing unit 16a, and each control board other than the communication board and the control board D1 indicated by each board ID stored in the storage unit 20 Determine whether it is operating normally. Note that the state of not operating normally here is not a state of not operating at all, but each control board other than the communication board and the control board D1 has reached some predetermined state, so that all are operating normally. That is not the case. The control board D1 itself is determined to be normal as long as at least this processing can be performed.

  When there is a control board other than the communication board and the control board D1 that is determined not to operate normally, the board control unit 18a stores a state mode table stored in the storage unit 20 so as to reduce the power consumption of the board. Rewrite. That is, the priority order of the boards that does not reduce the power consumption is changed even when the suppliable power is reduced.

  Note that the communication device 2 employs an n + 1 redundant configuration for the control board. That is, the substrate state mode control process is performed using one of the plurality of control boards as a master control board. The other control boards among the plurality of control boards are set as slave control boards, and the board state mode control process is performed only when the master control board fails. In this way, only one of the plurality of control boards can transmit the sleep signal. Note that when the communication device 2 is activated, it is desirable that the master control board is activated prior to other boards.

  As described above, in the second embodiment, the control board that controls the board state mode is separated from the power board that supplies power. This also makes it possible to prevent the entire communication device 1 from stopping even when the suppliable power is reduced due to a failure of the power supply device or the like. Further, since it is not necessary to provide a block for controlling the substrate state mode on each power supply substrate, the power supply device can be configured compactly.

  In the first embodiment and the second embodiment, the example in which the present invention is applied to the communication apparatus has been described. However, the present invention can also be applied to other circuit control apparatuses other than the communication apparatus.
