Description

The energy-saving method of the service board, the main control board, the service board and the access device. The application is submitted to the China Patent Office on March 23, 2011, and the application number is 201110070966.9. The priority of the Chinese patent application of the control board, the service board and the access device is incorporated herein by reference.

The present invention relates to the field of communications, and in particular, to an energy-saving method for a service board, a main control board, a service board, and an access device. Background technique

Energy conservation and emission reduction is one of the important tasks of the government in recent years. As a major consumer of electricity, the telecommunications network must also assume this social responsibility. For the energy saving of the telecommunication network access device, the prior art often uses an energy saving scheme for controlling the working mode of the service board.

The working mode of the control service board is to make the chip set to different working modes according to the state of the port and the data traffic of the port, such as reducing the sending power, interrupting the handshake cell with the user terminal or uninstalling the software on the chip. The energy saving solution achieves the purpose of reducing the energy consumption of the access device by minimizing unnecessary work on the chip. However, the energy saving solution can only reduce the power consumption of the chip. The system cannot eliminate the unnecessary power consumption generated by the logic chip on the service board, so the energy saving efficiency of the solution is limited.

In order to make up for the above-mentioned deficiencies of the power-saving scheme of the above-mentioned control service board, the prior art has also proposed an energy-saving scheme for configuring the service board to be powered down.

After the service board is powered off, the maintenance engineer of the carrier needs to manually reconfigure the service card when it is determined that the service board is not configured with the service or all the ports are deactivated. On the board, manually configure the service board to power on. The energy-saving scheme can reduce the power consumption of all the chips on the service board when the service board is not configured with the service or all the ports are deactivated, thus reducing the energy consumption of the access device.

The energy-saving scheme can eliminate the power consumption of all the chips on the service board when the service board is not configured with the service or all the ports are deactivated. Although the power consumption of the access device can be further reduced, the energy-saving efficiency is improved. However, due to the large number of access devices on the current network, it is difficult to calculate and manage the usage of each board on each access device. Manually configuring the service board for power failure is not only a heavy workload, but also a complicated operation. If you need to re-enable the service board, you need to manually send the power-on configuration command. Therefore, the maintenance cost of the energy saving scheme is large. Summary of the invention

The embodiments of the present invention provide an energy-saving method for a service board, a service board, a main control board, and an access device, which not only improve energy-saving efficiency, but also reduce maintenance costs in an energy-saving process.

In order to achieve the above object, the embodiment of the present invention adopts the following technical solutions:

The chip and logic chips on the board enter a power-saving state.

A main control board includes: a first timing controller, configured to periodically detect a service board, to confirm whether the service board meets a condition for entering a sleep mode, and when the service board meets a condition for entering a sleep mode And the second timer controller is configured to: after the timeout period of the sleep timer expires at least once, if the service board can meet the condition for entering the sleep mode after each timeout, The service board sends a sleep command to indicate that the chip and the logic chip on the service board enter a power-saving state.

Example 3

This embodiment provides an energy saving method for a service board. As shown in FIG. 5, the method includes the following steps. The main body of these steps is the main control board on the access device, and other access device components that can be used to manage and control the service board functions are known to those skilled in the art.

501. Check the service board periodically to check whether the service board meets the conditions for entering the sleep mode.

Specifically, after the access device is started, the main control board starts the detection timer, and periodically detects all the service boards in the access device to check whether a service board meets the conditions for entering the sleep mode. The time of the detection timer can be set by software according to the actual situation of the connected device.

The conditions for entering the sleep mode are: but not limited to: the service board is in the normal state, and the service flow is not configured on the service board; or the service board is in the normal state, and all ports on the service board are deactivated. Or, the service board is in a state other than the normal state and the sleep state. The other states include the configuration state, the auto-discovery state, and the abnormal state of the board.

Figure 6 shows the situation in which the various states described above migrate to each other during the operation of the service board. For example, the service board in the configuration mode is in the normal state after the configuration is complete. The service board in the auto-discovery state is in the sleep state when the board is not confirmed for a long time. If the communication is normal, the board is in the configuration state. After the board is confirmed, the board is in the configuration state. If the board is in the normal state, the board is in the abnormal state.

In the embodiment of the present invention, if the service board in another state has not returned to the normal state after the detection timer and the sleep timer described below have timed out, the state is migrated to the sleep state by the following method.

502. When the service board meets the conditions for entering the sleep mode, the main control board starts the sleep timer.

Specifically, after the time set by the detection timer ends (ie, the detection timer expires), if the main control board detects that a service board satisfies the condition of entering the sleep mode (ie, the three conditions described in step 501) If any of the service boards meets the conditions for entering the sleep mode, the detection timer is restarted. After the timer expires, the next service board enters the sleep mode detection. The time of the sleep timer and the number of timeouts can be set by software according to the actual conditions of the access device. 503. After the sleep timer expires at least once, the main control board determines whether the service board can meet the condition of entering the B-mode after each time the sleep timer expires.

504. If the service board can meet the conditions for entering the sleep mode after each timeout of the sleep timer, the main control board sends a sleep command to the service board to indicate that the chip and the logic chip on the service board enter. Energy saving status.

Specifically, the timeout period of the sleep timer is set to at least one time. After the timeout period set by the sleep timer ends (ie, the sleep timer expires), if the main control board detects that the sleep mode is satisfied in the above step 502, If the service board still meets the condition, the next time and the detection step after the timeout are performed.

If the service board detects that the service board that meets the conditions for entering the sleep mode in the above step 502 no longer satisfies the condition after the timeout of the sleep timer, the sleep timer is terminated and the detection timer is restarted.

505. The main control board receives a dormancy accept message sent by the service board, where the dormancy accept message is generated by the service board according to the sleep command.

Specifically, after receiving the sleep command sent by the main control board, the service board can respond to the command, that is, generate a dormancy accept message, and then send the dormancy accept message to the main control board to notify the main control board. The service board enters the sleep mode.

506. The main control board saves the status of the service board as a sleep state.

Specifically, the main control board is responsible for managing all the service boards on the access device, and the status information of each service board is saved. After receiving the dormancy acceptance message fed back by the service board, the main control board will The status information corresponding to the service board saved by itself is changed to the sleep state.

The time relationship between the steps in steps 501 to 506 will be described by taking FIG. 7 as an example.

The "0" position on the time axis of the main control board indicates that the access device is started at this time. When the timeout period for setting the detection timer is 10 minutes, the "10" position on the time axis of the main control board indicates that the detection timer has timed out at this time. At this time, if the main control board detects that a service board meets the conditions for entering the sleep mode, the sleep timer is started immediately.

The timeout period for setting the sleep timer is 5 minutes, and the number of timeouts is 6 times. Each time period after the "10" position on the time axis of the main control board indicates the timeout period of the sleep timer. The number of time periods indicates the sleep timing. Timeout Number. After the timeout period, the main control board checks the sleep condition of the service board. If the service board can meet the conditions for entering the sleep mode, the main control board sends a sleep to the service board at the "40" position. command. After receiving the successful response from the service board, the main control board changes the state of the locally saved service board to the sleep state.

After the service board is hibernated, basic communication can be maintained only through the master and slave serial ports and the service board.

507. The main control board detects whether the service board meets the conditions for exiting the sleep mode.

Specifically, the main control board can have the function of restoring the service board in the sleep state from the sleep state to the normal state, in addition to the service board that can enter the sleep mode. Therefore, the energy saving method of the service board may further include: the main control board detects all the service boards on the access device, and determines whether a service board meets the conditions for exiting the sleep mode.

The conditions for exiting the sleep mode include, but are not limited to, the service board is in the dormant state, and the service flow configuration is established on the service card. The service board is in the dormant state and the port is activated on the service board. Operation; or, the status of the service board moves from a state other than the normal state and the sleep state to a normal state.

508. When it is detected that the service board meets the conditions for exiting the sleep mode, send an exit sleep command to the service board to indicate that the chip and the logic chip on the service board exit the power saving state.

Specifically, when the main control board detects that the service board meets the condition for exiting the sleep mode (ie, any one of the three conditions described in step 507), the main control board sends an exit hibernation command to the service board to indicate the The chipset and logic chip on the service board exit the power saving state.

If the service board does not detect that the service board meets the conditions for exiting the sleep mode, the service board continues to check whether the service board meets the conditions for exiting the sleep mode.

509. Receive a normal message of the board sent by the service board. The normal message of the board is generated after the service board exits the sleep mode according to the exiting sleep command.

Specifically, after receiving the exiting sleep command sent by the main control board, the service board can respond to the command, and then perform the operation of exiting the sleep mode, so that the chip and the logic chip on the service board exit the energy-saving state. Then, a normal message of the board is generated, and the message is sent to the main control board to notify the main control board that it has returned to the normal state.

510. The state of the service board is saved as normal.

Specifically, after receiving the normal message of the board sent by the service board, the main control board changes the status information of the service board that is saved to the normal status. It should be noted that: the communication between the service board and the main control board in the dormant state can use the master-slave serial port, and other channels can be used as long as the CPU of the service board can be guaranteed (Central Process ing Uni t, CPU) The message can be received and processed on the main control board, and the normal handshake between the service board and the main control board can be ensured.

In addition, the detection timer and the sleep timer can also be the same timer, that is, only one timer is set in the main control board. When the access device is started, the timer is also started, and then at least two timesout occurs, after each timeout. Check whether the service board meets the conditions for entering the sleep mode. If the service board meets the conditions of the next time and the timeout, if the service board meets the conditions for entering the sleep mode after each timeout, follow the above energy-saving method. Operation, if the result of one test is that the condition for entering the sleep mode is not satisfied, the timer is restarted, and the number of timeouts is recalculated from zero.

As shown in Figure 8, the timeout period of the timer is set to 20 minutes, and the number of timeouts is 2, after the first 20 minutes of the sleep condition detection, if the service board meets the conditions for performing the sleep mode, the process continues. The second 20-minute delay, if the service board can still meet the conditions for performing the sleep mode after the timeout, the subsequent sleep operation can be performed.

In the energy-saving method of the service board provided by the embodiment, after receiving the sleep command sent by the main control board, the service board can control the chip and the logic chip on the service board to enter the energy-saving state, because the service board is based on When the sleep command enters the sleep mode, the logic chip can also enter the power-saving state, thus improving the energy-saving efficiency of the service board. In addition, since the chip and the logic chip enter the power-saving state, the sleep command sent by the main control board is automatically controlled, and no additional manual maintenance operation is required, thereby reducing the maintenance cost in the energy saving process. At the same time, the energy-saving method can also make the service board in the dormant state recover from the sleep state to the normal state through the automatic control of the main control board when the condition of exiting the sleep mode is satisfied, thereby further reducing the maintenance cost.

The embodiment also provides a main control board. As shown in FIG. 9, the main control board includes: a first timing controller 91, configured to periodically detect a service board, to confirm whether the service board meets the sleep mode. a condition, and when the service board meets the condition of entering the sleep mode, the sleep timer is started; the second timing controller 92 is configured to: after the timeout of the sleep timer expires at least once, if the service is timed after each timeout If the board can meet the conditions for entering the sleep mode, the device sends a sleep command to the service board to indicate that the chip and the logic chip on the service board enter a power-saving state.

The main control board may further include: a receiving module 93, configured to receive a response message sent by the service board;

94. When the response message received by the receiving module 93 is a dormancy accept message, the state of the service board is saved to a dormant state, and the response message received by the receiving module 93 is a single Board normal message, guarantee The status of the service board is normal; the sleep exit module 95 is configured to send an exit sleep command to the service board to indicate the status when the condition that the service board meets the exit sleep mode is detected. The chipset and logic chip on the service board exit the power saving state.

The steps performed by the above controllers and modules have been described in detail above, and are not described herein again.

The main control board provided in this embodiment performs timing detection on the service board, so that the chip and the logic chip on the service board that meet the conditions of entering the sleep mode enter the energy-saving state, because the service board satisfies the condition of entering the sleep mode. The logic chip can also enter the energy-saving state, thus improving the energy-saving efficiency of the service board. In addition, since the chip and the logic chip enter the energy-saving state, it is automatically judged and controlled by the main control board, and no additional manual maintenance operation is required, thereby reducing the maintenance cost in the energy saving process. At the same time, the main control board can also exit the module through the sleep mode. When the service board meets the conditions for exiting the sleep mode, the chip and the logic chip on the service board are in the energy-saving state, and no additional manual maintenance operations are required. Reduced maintenance costs.

Example 4

This embodiment provides an energy saving method for a service board. As shown in FIG. 10, the method includes the following steps. The main body of these steps is the service board on the access device.

1001: The service board receives the sleep command sent by the main control board.

Specifically, according to the method described in Embodiment 3, when the main control board determines that the service board can enter the sleep mode, the service board sends a sleep command to the service board. After receiving the command, the service board receives the sleep command. Controlling the chip and the logic chip on the service board to enter a power-saving state, the control step may specifically be, but not limited to, the operations described in steps 1002 to 1006 below.

1002. The service board generates a dormancy acceptance message according to the sleep command.

1 003. The service board sends the dormancy acceptance message to the main control board.

1004. The service board sets a sleep flag in the storage device.

1005. The service board performs a reset operation.

1006. The service board controls the chipset and the logic chip on the service board to enter a power saving state according to the sleep flag.

Specifically, the service board responds to the sleep command, and generates a sleep acceptance message, and then sends the message to the main control board. Then, the service board sets a sleep flag in the storage device, and the storage device may be on the service board.

FLASH (flash) memory or other memory, as long as the data in the memory is reset later on the service board It will not be lost during operation. Next, the service board performs a reset operation, and then enters a sleep mode according to the sleep flag in the storage device, that is, the chip and the logic chip thereon enter a power-saving state.

After the reset operation is performed on the service board, the logic software and the chip software are not loaded on the logic chip and the chip, so that the chip and the logic chip enter a power-saving state. It is also possible to reduce the power consumption of the logic chips and the chipset on the service board entering the sleep mode by means known to those skilled in the art.

The time relationship between the steps in steps 1001 to 1006 will be described using FIG. 11 as an example.

The “0” position on the timeline of the service board indicates that the access device is started at this moment. The settings of the detection timer and the sleep timer are the same as those in Figure 7. The service board sent by the main control board is received by the service board in the "40" position on the time axis of the main control board. At this time, the service board performs a reset operation after recording the sleep flag in the FLASH. Later, during the reset process, the service board reads the sleep flag from the FLASH, confirms that it needs to enter the sleep state, and does not load the logic software and the chip software during the subsequent loading process, so that the logic chip and the chip set enter a power-saving state.

After the service board enters the hibernation state, basic communication can be maintained only through the master and slave serial ports and the service board.

1007. Determine whether an exit sleep command sent by the main control board is received.

Specifically, according to the description of Embodiment 3, the main control board can have the service board that is in the dormant state return to the sleep state, and the service board can be restored from the sleep state to the normal state. Features. When the main control board detects that a service board on the access device meets the conditions for exiting the sleep mode, it sends an exit hibernation command to the service.

If the service board does not receive the exit hibernation command, it continues to detect the exit hibernation command until the exit hibernation command is received.

If the service board receives the exit sleep command, the control chip and the logic chip are controlled to be in a normal working state according to the exit sleep command. The control step may be specifically but not limited to the operations described in the following steps 1008 - 1011.

1008. Set the exit sleep flag in the storage device.

1009. Perform a reset operation.

1010. According to the exiting the sleep flag, the control chip and the logic chip enter a normal working state.

1011. Report the normal message of the board to the main control board.

Specifically, after receiving the exiting sleep command, the service board sets an exit sleep flag in the storage device, where the storage The device may be a FLASH memory or other memory on the service board, as long as the data in the memory is not lost when the service board performs a reset operation later. Next, the service board performs a reset operation, and then exits the sleep mode according to the exit sleep flag in the storage device, that is, the chip and the logic chip thereon enter the normal working state. Finally, the service board reports the normal message of the board to the main control board to notify the main control board. The service board has been transferred to the normal state and can process the service normally.

After the reset operation is performed on the service board, the logic software and the chip software are added to the logic chip and the chip to enable the chip and the logic chip to enter a normal working state. It is also possible to adopt the corresponding method of exiting the sleep mode according to the energy saving method adopted in step 1006.

It should be noted that: the communication between the service board and the main control board in the dormant state can use the master-slave serial port, and other channels can be used as long as the CPU of the service board can receive and process the message of the main control board. And can ensure a normal handshake between the service board and the main control board.

In the energy-saving method of the service board provided by the embodiment, after receiving the sleep command sent by the main control board, the service board can control the chip and the logic chip on the service board to enter the energy-saving state, because the service board is based on When the sleep command enters the sleep mode, the logic chip can also enter the power-saving state, thus improving the energy-saving efficiency of the service board. In addition, since the chip and the logic chip enter the power-saving state, the sleep command sent by the main control board is automatically controlled, and no additional manual maintenance operation is required, thereby reducing the maintenance cost in the energy saving process. At the same time, after receiving the exit hibernation command sent by the main control board, the service board can control the chip and the logic chip on the service board to enter the normal working state, that is, the service board exits the sleep mode, and the process does not need additional Manual maintenance operations further reduce maintenance costs.
