The following is a detailed description of another embodiment of the present application.
Fig. 2 is a single board structure diagram according to the related art, and as shown in fig. 2, the present power control system mainly includes an input power monitoring module, a power module, and a programmable control module. The input power supply monitoring module monitors the power supply state. And the programmable control module operates according to a logic file programmed in advance and controls the power supply to be switched on and off according to the received power supply state information.
Although the scheme in the related art uses the programmable logic device to perform power-on and power-off control, two problems exist:
1. in the stage of debugging and maintaining the single board, especially in the stage of testing the power supply, the power supply modules need to be repeatedly powered up and down, and if the Logic of a control module CPLD (Complex Programmable Logic Device) is directly operated to control, the normal power-up Logic is easy to be abnormal; if the operation is performed through the resistor at the enabling end of the welding power supply module, the efficiency is low and the welding is easy to be wrong.
2. The logic upgrading of the power supply monitoring module can only be realized by connecting a sintering socket on the single board with a computer for upgrading after the single board is powered off, the expandability is poor, and after the single board is produced and delivered, if a fault occurs in the aspect of power supply logic, maintenance personnel can only go to the site for upgrading, which wastes time and labor.
The technical problem that this application will solve is:
1. the programmable single board power-on and power-off control method and the programmable single board power-on and power-off control device are provided, so that the power-on and power-off of each power module can be flexibly controlled in the debugging and maintenance processes of the single board, and the normal logic time sequence function is not influenced;
2. the remote online upgrading function of the programmable power supply monitoring logic device can be realized, the upgrading of the power supply monitoring logic is completed in the normal operation process of the single board, and the interruption of the current service cannot be caused.
A programmable single-board power-on and power-off control device:
fig. 3 is a schematic structural diagram of a programmable on-board power-on and power-off control apparatus according to another embodiment of the present application, as shown in fig. 3, including the following modules: the power supply monitoring system comprises a power supply monitoring module (a programmable power supply time sequence control and voltage monitoring chip), a power supply module and a programmable control module (CPLD); the system also comprises a selector module, a CPU module and the like;
the power supply monitoring module integrates the functions of voltage monitoring and programmable time sequence control, only one chip is used for realizing the conventional design scheme, the cost is saved, and the design is simpler. The input end of the power supply monitoring module is connected with the output end of each power supply module to realize the monitoring of each voltage, and the output end of the power supply monitoring module is used for connecting the control signal with the set time sequence with the control module and the selector; the control module can also output a power supply control signal to the selector; the selector can perform alternative gating on control signals of the power supply monitoring module and the control module, so that the power supply monitoring module or the control module can electrically control the power supplies to be powered on and powered off. The power supply monitoring module has voltage monitoring and logic programmable functions and controls the normal working time sequence of the single-board power supply, and the control module (CPLD) is a programmable logic device and does not have the voltage monitoring function, so that the function of the power supply monitoring module cannot be completely replaced. Because the power module of the single board is controlled by an enable control signal, the control function can be realized by the power monitoring module or the control module, and the power monitoring module and the control module can work independently without mutual influence.
The CPU module is used as a control center and applied to each single board, and the online upgrading function of the power supply monitoring module needs to be realized by the aid of the CPU module. The network connection module can access the single board to the network to realize the remote control of the single board and download the software/logic version file to the FLASH, the CPU is connected with a CPLD through a localbus bus, and because the program of the logic device is sintered through a JTAG interface, the CPLD converts the software/logic version file into a JTAG interface signal and outputs the JTAG interface signal to a selector on the single board, thereby realizing the online upgrade of the software/logic version.
A programmable single-board power-on and power-off control method comprises the following steps:
fig. 4 is a flowchart of a power-on and power-off control method of a programmable single board according to another embodiment of the present application, as shown in fig. 4, including the following steps:
402, in the process of controlling the power-on of each power supply, monitoring whether each voltage is normal or not by a power supply monitoring module, and monitoring the output voltage value; if the voltage value is abnormal, reporting a power supply abnormal interrupt to the central processing unit CPU for processing; if the power is normal, the single board can be normally powered on.
In step 403, is the selector gated by the control module? If not, continuing to switch through the power supply monitoring module, and turning to the step 404; if so, the handover is confirmed and the process goes to step 405.
In step 404, the default is to gate the power monitoring module, i.e. no switching is needed, and then the power monitoring module will monitor whether the voltage values of the power supplies are normal or not.
Step 405 gates the control of the power supply by the control module, i.e. the CPLD, and at this time, 3 operation functions can be realized:
the power supply module is electrically controlled up and down by a CPLD execution power supply of the function 1 and the control module;
and 2, starting to upgrade the power supply monitoring module on line. As described above, the power monitoring logic device and the CPLD of the control module can work independently, when the CPLD of the control module takes over the control of the power module, the power monitoring logic device can start to be upgraded online, and after the upgrade is completed, the power monitoring module can be switched to continue to control, and the single board can operate normally in the whole process;
function 3, debug mode. The power module is tested and debugged or the single board is maintained, the power module needs to be frequently switched on and off, and at the moment, the control on and off signals of the power module can be conveniently controlled by arranging the corresponding power control register in the control module CPLD.
The following is a further description with reference to specific examples.
The first embodiment is as follows: power supply control switching method
Fig. 12 is a diagram of an apparatus for supporting power control switching according to the present application, as shown in fig. 12, a power monitoring module includes a voltage monitor (a/D), a programmable logic device PLD, and a control module includes a power status register, a power control register, and the like, and both the power status register and the power control register are customized. The specific implementation mode is as follows:
the first step is that the power supply monitoring module has a voltage monitoring function and can transmit voltage information of each power supply to the control module, and the control module stores the voltage information into the power supply state register;
the programmable logic device PLD in the power supply monitoring module operates according to the set logic time sequence file, outputs the power supply control signal to the selector, and controls the power supply modules to be powered on and powered off after being gated by the selector; after each power supply is normally powered on, the power supply monitoring module transmits a power-on result to the control module, corresponding to other signals in fig. 12, so that the control module knows the state and the switch information of each power supply module;
a plurality of power supply control registers are defined in the control module in the third step, the power supply control registers correspondingly control the switches of the power supply modules one by one, and the control module can take over the control of the states of the power supply modules at the moment according to the power supply information acquired in the third step;
the fourth step is that the selector gates the control module, the power module is controlled by the control module, and the power monitoring module is in an idle state at the moment and can perform operations such as online upgrading and the like;
and fifthly, when the power supply monitoring module is required to control, the selector is used for gating the power supply monitoring module.
Therefore, the power control switching of the whole single board is realized, the power supply cannot be powered off in the switching process, and the service is not influenced.
The second embodiment is as follows: on-line upgrade of power supply monitoring module and control module
Fig. 6 is a structural diagram of online upgrade of a power supply monitoring module according to a second embodiment, fig. 7 is a structural diagram of online upgrade of a control module according to the second embodiment, as shown in fig. 6 and 7, the online upgrade apparatus for a power supply monitoring module according to the present application refers to fig. 6, and the online upgrade apparatus for a control module CPLD refers to fig. 7. Fig. 5 is a flowchart of on-line upgrade of a board according to another embodiment of the present application, as shown in fig. 5, including the following steps:
at step 502, determine if unicast is an upgrade? The system is initially defaulted, and logic upgrading needs to be confirmed, so that random change of the system logic version is prevented. If the upgrade is not confirmed, the method waits all the time; after the single board confirms the upgrade, see step 503,
in step 504, it is determined whether to upgrade the power monitoring module? If yes, the selector gates the power supply monitoring module for upgrading; if not, the selector strobes the control module to upgrade.
Because the power supply monitoring module and the control module are programmable logic devices, the power supply monitoring module and the control module can be upgraded, at the moment, which device needs to be upgraded needs to be judged, and the selector can gate the device needing to be upgraded.
And 505, the single board normally operates. After the programmable logic device is upgraded, the new software/logic version becomes effective after the device is reset, and then the programmable logic device can start to work with the new logic software version.
The method realizes remote control logic upgrade and does not influence the normal service of the system. The prior art scheme can not be upgraded remotely, and the system expandability is poor.
The third concrete embodiment: online upgrade of backplane switch power management system
Fig. 9 is a diagram of an online upgrade apparatus for a service board or a power monitoring module of a switch board and a CPLD in a backplane-type switch system according to a third embodiment, as shown in fig. 9, an online upgrade process of the system including a main control board, a service board, a switch board, a service board and a switch board can be understood with reference to fig. 8. Fig. 8 is a schematic diagram of an online upgrade method for each board of a backplane switch system according to a third specific embodiment, as shown in fig. 8, including the following steps:
step 803 and step 804, the service board and the switch board respectively put the received upgrade file into the FLASH of the board;
The method realizes the remote logic upgrade of each single board in the whole switch system, does not influence the normal service of the system, is convenient for upgrade maintenance and has high reliability.
Example four: single board power supply debugging
Fig. 11 is a structural diagram of a programmable power-on/power-off control apparatus of a single board according to the present application, and fig. 10 is a flowchart of a programmable power-on/power-off control method of a single board according to the present application, and as shown in fig. 10 and 11, the power supply is debugged and maintained without affecting the normal power-on sequence logic of the single board, assuming that the power supply is a power supply network diagram of the single board, the power supply monitoring system described in the present application monitors the 6 voltage values, and adds a corresponding register in the control module to control the switches of the 6 power supply modules. The veneer has a timing requirement, 12V is electrified at the earliest and 1.2V is electrified at the latest. The normal power-on sequence can control each power supply to be sequentially turned on according to requirements through the programmable power supply monitoring module.
In the debugging and maintaining process, because the power supply monitoring module stores normal power-on sequential logic, how to operate is not done, the application only operates the register of the control module:
1. for example, when a 3.3V power supply needs to be tested, the register of the power supply 1 is opened only through the control module CPLD, and then the switch of the power supply 3 is independently controlled;
2. for example, when the influence of 5V on 1.2V voltage is tested, the registers of the power supplies 1, 2 and 6 are independently controlled by the control module CPLD, and other power supplies are turned off;
3. for example, when the influence of 5V on 1V voltage is tested, the registers of the power supplies 1, 2 and 4 are independently controlled by the control module CPLD, and other power supplies are turned off;
for the CPLD, the switches of the power supply modules can be controlled in a mode of operating the register, the CPU can be operated when working normally, and the sequential logic of the power supply monitoring module is not required to be changed completely. The CPLD is equivalent to a standby controller, and the power supply monitoring module is a main controller. In the existing scheme, only one controller is provided, and the original control logic is easily disturbed by directly operating the controller.
The method used by the application adopts a mode of combining an independent programmable power supply chip with a CPLD to realize the monitoring and time sequence control of each power supply on the single board and the remote online upgrading function of the programmable logic device.
