Detailed Description
When the CPE (Customer Premises Equipment) is powered down, the device can report to the CO (Central Office) in time, and this function is called "tracking Gasp (temporary heritage)".
The Dying Gasp function requires that a specific number of messages in a fixed format are sent out when the single board is powered down, and the messages are used for informing the equipment of faults. The function needs a capacitor with enough capacity to store energy, a power-down monitoring chip is used for monitoring power down and triggering interruption, a single board load is used for power supply management after power down, and a system can send a certain number of marking Gasp messages with fixed formats according to requirements after the interruption.
The prior art realizes the Dying Gasp function on the daughter card, namely, designs enough energy storage capacitors, power failure monitoring chips and corresponding Dying Gasp modules on the daughter card.
However, in this way, for the distributed system, the sub-cards are very various, if the playing Gasp function is implemented on each sub-card, the related hardware circuit and the matched software modification are required on each sub-card, and the design cost is very high; and the Dying Gasp module can be realized only by a specific chip, and the module cannot be realized for some low-speed daughter cards, so that the low-speed daughter cards cannot support the Dying Gasp function, and the use scene of the daughter cards is limited.
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
The embodiment of the application provides a power-off information transmission method. As shown in fig. 1, the hardware involved in the method of the present invention includes: the main control board, the daughter card and the backboard; the main control board and the daughter card are arranged on the backboard, and the backboard is used for supplying power. As shown in fig. 2, the specific scheme flow of the embodiment of the present application is as follows:
s10, the backboard supplies power to the main control board and the daughter card; the main control board and the daughter card acquire the power supply voltage of the backboard, and adjust the power supply voltage to be working voltage;
the main control board and the daughter cards are arranged on the backboard, and the backboard is used for supplying power.
Preferably, the power supply voltage of the backboard is 48V.
The working voltage of the main control board and the daughter card is lower than the power supply voltage of the backboard, so that the main control board and the daughter card are respectively provided with a power supply conversion module for converting the power supply voltage into the working voltage.
Preferably, the working voltage of the main control board/sub-card is 12V.
S20, after the main control board detects that the power supply voltage is reduced to a first threshold value, the working module of the main control board is closed;
the main control board is provided with a slow starting circuit, the slow starting circuit is provided with a first threshold value, when the input voltage is smaller than the first threshold value, the slow starting circuit is powered down, and PG signals of the slow starting circuit are changed after the power down, so that the purposes of notification and detection are achieved. And the slow start circuit is powered down, namely, the main control board detects that the power supply voltage is reduced to a first threshold value.
The PG signal, when standby, the PG circuit outputs zero level self-checking signal to the host, the host stops working and is in standby state; after controlled start, the PG circuit delays for hundreds of milliseconds to jump to +5V from zero level after the output voltage of the switch power supply is stable, and sends a high-level signal to the host to inform the host to trigger the system to automatically close before the power supply is powered off.
The back plate is also used for sending a voltage enabling signal to the main control board, the purpose of informing the main control board is achieved through the enabling signal, and the main control board receives different enabling signals, namely, the power supply voltage is detected to be reduced to a first threshold value (the back plate is set to send an effective enabling signal when the power supply voltage is larger than the first threshold value, and an invalid enabling signal is sent when the power supply voltage is smaller than or equal to the first threshold value).
The enabling signal is a control signal, and when the enabling signal is invalid, the corresponding equipment is in a standby state; when the enable signal is valid, the corresponding device will operate.
When the logic module detects or receives the change of the PG signal of the slow start circuit, the main control board is controlled to close the working module, wherein the working module can be a module which comprises a CPU and is irrelevant to generating and sending a decoding Gasp message; such as all but logic blocks, dying Gasp blocks, and switching chips.
S30, starting a first energy storage circuit to supply power to a preset module;
the first energy storage circuit charges when the main control board works normally, and charges the preset module after the main control board is powered down.
Preferably, the preset module includes: logic module, dying Gasp module and exchange chip.
S40, generating a marking Gasp message according to a preset template;
the slow start circuit can send abnormal information (changing PG signals) after the power supply voltage is reduced to a first threshold value to the logic module and the Dying Gasp module; the logic module controls the working module of the main control board to be powered off, and the Dying Gasp module generates Dying Gasp messages according to a preset template.
S50, sending the marking Gasp message to the daughter card;
the generated Dying Gasp message is sent to the physical chip of the daughter card through the exchange chip.
S60, the daughter card receives the marking Gasp message and then forwards the marking Gasp message;
the physical chip of the daughter card forwards the received message, and the received Dying Gasp message is also forwarded.
It should be noted that, if there are multiple sub-cards, the forwarding Gasp message may select a specific sub-card for forwarding, and not all sub-cards need to forward.
S70, after the daughter card detects that the power supply voltage is reduced to a second threshold value, closing a working module of the daughter card; the second threshold is less than the first threshold.
Preferably, the first threshold is 36V and the second threshold is 34V.
In addition, for the turning Gasp function, the turning Gasp message sent by the turning Gasp function is a signal with a certain time length, so that the power-off time (the power-off time refers to the time when all circuits and elements in the device are powered off and stop working) of the daughter card as the forwarding message needs to have a certain time interval with the power-off time of the main control board to finish the forwarding of the turning Gasp message.
It should be noted that, the main control board is internally provided with the energy storage circuit, so that the normal operation of the Dying Gasp can be continuously ensured for a period of time after the power is turned off, so that the power-off time of the main control board and the power-off time of the daughter card are actually ensured to have a certain interval, thereby completing the generation and the forwarding of the Dying Gasp message.
In this way, the second threshold value is set smaller than the first threshold value, so that in the voltage reduction process, the power-down of the main control board is triggered firstly, and then the power-down of the daughter card is triggered, so that the generation of the Dying Gasp message and the power-down of the daughter card after forwarding can be continuously completed after the power-down of the main control board, and the normal implementation of the Dying Gasp function is ensured.
Therefore, by realizing the Dying Gasp function on the main control board, in the power-down process of the whole machine, the main control board triggers the Dying Gasp message after power-down, and the message is forwarded to each sub-card through the exchange chip, so that the Dying Gasp message is sent. Therefore, a power-down monitoring circuit and a load power supply management circuit on the power-down sub-card can be saved, the development work of the Dying Gasp module software and logic of the power-down sub-card is saved, the requirement on the sub-card is reduced, and the sub-card is not required to be additionally upgraded, so that the cost is greatly reduced.
In this way, for the distributed system of a plurality of sub-cards, after the cost of a single sub-card is reduced, the more the number of slots of the whole sub-card is, the more the cost is reduced, so that the cost of the distributed system is greatly reduced; and the daughter card does not need to develop the Dying Gasp characteristic, and directly forwards the Dying Gasp message as a common message, thereby greatly shortening the development period of the product.
Therefore, a power-down detection module, a Dying Gasp module and the like do not need to be installed on the daughter card, and only a physical chip and a simple control module are required to be installed, so that the cost can be greatly saved. The power supply voltage is reduced to a first threshold value, then the main control board is powered off, and the sub-card is powered off after the power supply voltage is reduced to a second threshold value, so that the main control board is powered off firstly, and the sub-card is powered off later; in addition, the power of the main control board is high, the power of the sub-card is low, so that the main control board can consume the electric energy of the energy storage circuit preferentially even if the power-down time is the same, and the main control board is powered down first.
In addition, after the main control board is powered down, the energy storage circuit turns off useless power supply on the single board and keeps the power supply to the Dying Gasp module, the logic device and the exchange chip, so that the power consumption of the main control board can be reduced, and the electric energy standard required to be stored by the energy storage circuit is reduced.
Preferably, as shown in fig. 2, the power-down information transmission method further includes:
s80, enabling the second energy storage circuit to supply power to a preset module of the daughter card by the daughter card; the equivalent capacitance of the second energy storage circuit is smaller than that of the first energy storage circuit.
The preset module of the daughter card is the physical chip, and the physical chip is used for forwarding the Dying Gasp message; and the method can also be used for forwarding other messages sent by the main control board.
In this way, the second energy storage circuit is arranged on the daughter card, so that the duration of the forwarding function of the daughter card can be maintained after the power failure of the daughter card, the available time for forwarding the forwarding of the forwarding Gasp message can be further prolonged, and the normal implementation of the forwarding Gasp function is further ensured.
It should be noted that, in this application, the equivalent capacitance is used to measure the relationship between the capacities of the first tank circuit and the second tank circuit, and the larger the capacity, the higher the general cost.
The equivalent capacitance of the second energy storage circuit is smaller than that of the first energy storage circuit, so that a large-capacity energy storage circuit does not need to be arranged on the daughter card, and the cost of a single daughter card is reduced while the normal implementation of a Dying Gasp function is ensured.
The CPU of the control board is connected with the logic device and the physical chip of the daughter card through the management bus; the exchange chip of the control board is connected with the control device and the physical chip of the daughter card through the data bus.

s3, starting the first energy storage circuit to supply power to the preset module;
s4, generating a marking Gasp message according to a preset template;
s5, the Dying Gasp message is sent to the daughter card so that the daughter card can forward the Dying Gasp message and close a working module of the daughter card after detecting that the power supply voltage is reduced to a second threshold value; the second threshold is less than the first threshold.
In this way, the second threshold value is set smaller than the first threshold value, so that in the voltage reduction process, the power-down of the main control board is triggered firstly, and then the power-down of the daughter card is triggered, so that the generation of the Dying Gasp message and the power-down of the daughter card after forwarding can be continuously completed after the power-down of the main control board, and the normal implementation of the Dying Gasp function is ensured.
Therefore, by realizing the Dying Gasp function on the main control board, in the power-down process of the whole machine, the main control board triggers the Dying Gasp message after power-down, and the message is forwarded to each sub-card through the exchange chip, so that the Dying Gasp message is sent. Therefore, a power-down monitoring circuit and a load power supply management circuit on the power-down sub-card can be saved, the development work of the Dying Gasp module software and logic of the power-down sub-card is saved, the requirement on the sub-card is reduced, and the sub-card is not required to be additionally upgraded, so that the cost is greatly reduced.

Therefore, a power-down detection module, a Dying Gasp module and the like do not need to be installed on the daughter card, and only a physical chip and a simple control module are required to be installed, so that the cost can be greatly saved. The power supply voltage is reduced to a first threshold value, then the main control board is powered off, and the sub-card is powered off after the power supply voltage is reduced to a second threshold value, so that the main control board is powered off firstly, and the sub-card is powered off later; in addition, the power of the main control board is high, the power of the sub-card is low, so that the main control board can consume the electric energy of the energy storage circuit preferentially even if the power-down time is the same, and the main control board is powered down first.
Preferably, the preset module includes: logic module, dying Gasp module and exchange chip.
