Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
The embodiment of the invention provides that a kind of reliability, stability are all relatively good, automaticity is high, and has method for managing power supply in the communication equipment of self-healing ability and use power-supply management system in the communication equipment of this method after breaking down.
As shown in Figure 1, method for managing power supply in the communication equipment that the embodiment of the invention provided may further comprise the steps at least:
A, use same power supply to be main control module and the power supply of at least one business module;
B, surpass the maximum rated power output of power supply in the total power consumption of main control module and business module, and before the maximum overload capacity that the arrival power supply can bear, main control module is automatically in predetermined a period of time, close at least one business module, and when the total power consumption of main control module and business module is lower than maximum rated power output, open pent business module again.
Because the present invention can surpass the maximum rated power output of power supply in the total power consumption of main control module (for example main control card) and business module (for example service card), and when the maximum overload capacity that the arrival power supply can bear, automatically in predetermined a period of time, close at least one business module, and when the power output of power supply is lower than maximum rated power output, again open pent business module, like this, when business module because at random factor, cause the maximum rated power output of the total power consumption of main control module and business module above power supply, and during the maximum overload capacity that in predetermined a period of time, can bear less than power supply, the present invention can be automatically in predetermined a period of time, close at least one business module, thereby make the total power consumption of main control module and business module be reduced to maximum rated power output at least, and then can realize power supply and main control module is set and the protection of the communication equipment of business module less than power supply;
Simultaneously, because when the present invention can also be lower than maximum rated power output at least in the power output of power supply, again open pent business module, because under a lot of situations the business module power consumption excessive be because factor at random (for example: the client's of the immediate communication that switch inserts quantity is at a time too much temporary transient), and after business module and power supply disconnect a period of time, cause the excessive enchancement factor of business module power consumption not exist, for example: after switch restarts, the client's of the immediate communication that inserts on it quantity has reduced a lot, make the power consumption of service card of switch can recover normal, at this moment, again open pent business module, make power supply be the business module power supply again, can recover operate as normal so that be disconnected the business module of power supply before, because being disconnected the business module recovery operate as normal of power supply before finishes automatically, so use communication equipment of the present invention have break down after, the ability of self-healing, so with existing communication equipment Comparatively speaking, use the better reliability of the communication equipment of this power supply, automaticity is higher, so it is relatively poor to have solved in the existing communication equipment use reliability, the technical problem that automaticity is lower.
Power supply among the present invention can bear big maximum overload capacity, be when facility communication system designs, the fault that may occur according to communication equipment (for example: after power module partly breaks down or extracts in the power supply, the power supply power output is less than equipment real work power consumption), analysis meter is calculated power supply maximum overload capacity (greater than the rated power of power supply), make power supply in the maximum rated power output that surpasses power supply, and before the maximum overload capacity that the arrival power supply can bear, guarantee the capable business module of closing reliably of main control module at predetermined certain hour.
Predetermined a period of time (can be about 10 seconds) is what specifically can be earlier obtains the maximum power dissipation that main control module and business module can bear according to the calculation of parameter of the electronic device that constitutes main control module and business module, and then selects or design can be born the power supply of maximum power dissipation in this a period of time of being scheduled to according to maximum power dissipation.
As shown in Figure 2, in the present embodiment, step B specifically may further comprise the steps:
B1, in the total power consumption of main control module and business module during greater than a certain predetermined POL, power supply sends first alarm signal to main control module, and in the total power consumption of main control module and business module during less than predetermined POL, stop to send first alarm signal, the performance number of predetermined POL is less than maximum rated power output;
B2, in the total power consumption of main control module and business module during greater than maximum rated power output, power supply sends second alarm signal to main control module, during less than maximum rated power output, power supply stops to send second alarm signal in the total power consumption of main control module and business module;
B3, after main control module receives second alarm signal, close at least one business module, the total power consumption that makes main control module and business module is less than predetermined POL, and do not receiving first alarm signal, when not receiving second alarm signal yet, pent power consumption module before opening.
Predetermined POL can artificially be set, for example can be set at size between maximum rated power output 60%～90% between some values, the effect of first alarm signal be to determine the total power consumption of main control module and business module reopen when being reduced to what degree before pent power consumption module.If what the total power consumption of main control module and business module reduced is not too low, pent power consumption module before reopening this moment so, the total power consumption of main control module and business module can rise in the relatively shorter time, though if cause main control module or the excessive enchancement factor of business module power consumption can disappear after a time, but this moment, this enchancement factor still also exists, and is disconnected the main control module of power supply and the effect that business module recovers operate as normal before that does not just have and makes.
As shown in Figure 3, in the present embodiment, further comprising the steps of:
The number of times that C, recording step B carry out, and after the number of times that repeats continuously reaches predefined numerical value, when the total power consumption of main control module and business module still surpasses maximum rated power output, main control module is closed at least one business module, the total power consumption that makes main control module and business module is sent the ALM signal simultaneously less than predetermined POL.
The purpose of repeated execution of steps B is, when carrying out a step B, because the time is shorter, perhaps cause the excessive enchancement factor of main control module or business module power consumption still also to exist, so need to carry out step B several times more, so can be after enchancement factor disappear, the business module that is disconnected power supply before making as soon as possible recovers operate as normal, has further strengthened the reliability of the communication equipment that main control module and business module are set.
After the number of times of repeated execution of steps B reaches predefined number of times, when the total power consumption of main control module and business module still can surpass maximum rated power output, usually cause main control module or the excessive enchancement factor of business module power consumption to need operating personnel to judge as the case may be, and then take measures to eliminate enchancement factor, undying repeated execution of steps B can't overcome such problem, for example: when the partial service module short circuit, restart business module, can't eliminate short circuit problem.
The mode of sending the ALM signal in the present embodiment can have multiple, for example: can adopt sounding, luminous mode, also the ALM signal can be inputed to special checkout equipment, check for operating personnel.
In the present embodiment, close the method for at least one business module, be specially:
According to the priority of predefined power consumption module, according to priority order from low to high, close the lower power consumption module of priority earlier, until the total power consumption of main control module and business module less than predetermined POL;
The method of pent power consumption module before opening is specially:
According to the priority of predefined power consumption module, according to priority order from high to low, open the higher power consumption module of priority earlier, until the total power consumption of main control module and business module greater than predetermined POL.
According to priority order from low to high, close the lower power consumption module of priority earlier; According to priority order from high to low, open the higher power consumption module of priority earlier and can guarantee that the higher priority business module works the longer time all the time, and then guarantee that prior function can keep the longer time.Certainly, closing or open power consumption module in the present embodiment also can be at random.
As shown in Figure 4, in the present embodiment, further comprising the steps of:
D, when the total power consumption of main control module and business module surpasses the maximum overload capacity that power supply can bear, power supply enters overcurrent protection, its output voltage reduces;
E, when the magnitude of voltage of the output voltage of power supply during, the connected power supply circuits of all business module automatic disconnection power supplies less than the under-voltage protection point of predefined business module;
When F, main control module detect all business modules and cut off the power supply voluntarily, send the ALM signal.
When the maximum overload capacity that the total power consumption of main control module and business module can bear greater than power supply; the output current of power supply is very high; at this moment; can judge the power output of power supply is whether the total power consumption of main control module and business module has reached the maximum overload capacity that can bear by the mode of gathering electric current; when the output voltage that reduces power supply; make the magnitude of voltage of output voltage of power supply greater than the under-voltage protection point of main control module; and during less than the under-voltage protection point of business module; can keep main control module work closing when thereby business module deducts the business module power consumption.
Owing to be mounted with more software program usually in the main control module, in a single day main control module is closed to restart and can be expended the more time, so only close business module in the such scheme, the method of keeping main control module work helps to reduce the total boot time of communication equipment, simultaneously, when monitoring by main control module or controlling business module, keep the operating state of main control module, can carry out related the closing or opening operation of above-mentioned present embodiment to business module by main control module, and then guarantee that communication equipment has self-healing function.
Open the method for business module in the present embodiment, can also may further comprise the steps:
After closing business module at least twice, identification is closed before the business module at every turn, and power consumption is all greater than the pairing address of business module or the identification code of rated power separately;
Make with address or identification code corresponding service module to be in closed condition, and when opening pent business module always, the priority of address or identification code corresponding service module is considered as not existing.
After closing business module at least twice, close before the business module at every turn, power consumption is all greater than the business module of rated power separately, the excessive reason of its power consumption is normally because internal fault, for example short circuit, can't make it recover operate as normal by the mode that restarts, so need identify these pairing address of business module that has fault or identification codes, and make it be in closed condition always, avoid existing the business module of fault to the whole influence that the communication equipment of business module, main control module is set.Close or when opening business module, the address that above-mentioned steps write down or the priority of identification code corresponding service module are considered as not existing, can avoid priority and in the process that opens or closes, can close normally or start, do not had the influence of the business module of fault with respect to the inconsistent business module of the priority of the business module that has fault.
Identification exists the pairing address of business module of fault or the method for identification code can have multiple in the present embodiment, for example: testing circuit can be set on business module, when the electric current that testing circuit detects the incoming traffic module surpasses the normal electrical flow valuve, send fault-signal, can judge that there is fault in which business module according to fault-signal then.
As shown in Figure 4, in the present embodiment, further comprising the steps of:
G, when the temperature of power supply surpasses predefined temperature, power supply enters overtemperature protection, its output voltage reduces;
H, when the magnitude of voltage of the output voltage of power supply during, the connected power supply circuits of all business module automatic disconnection power supplies less than the under-voltage protection point of predefined business module;
When I, main control module detect all business modules and cut off the power supply voluntarily, send the ALM signal.
When the power supply temperature is too high, can not cause the interior electronic device of power supply to burn out if do not reduce the total power consumption of main control module and business module immediately, so technique scheme can be at the magnitude of voltage of the output voltage of power supply during less than the under-voltage protection point of predefined business module, the connected power supply circuits of all business module automatic disconnection power supplies, thereby the total power consumption of reduction main control module and business module; And then the safety of each building block of assurance communication equipment.
When main control module detects all business modules and cuts off the power supply voluntarily, at this moment, the existing problem of business module normally can't self-healing solve (for example business module short circuit), so this moment, main control module sends the ALM signal, waits for that operating personnel check and get rid of the problem of power supply existence.
Because the under-voltage protection point of business module is greater than the under-voltage protection point of main control module, thus the output voltage of power supply during greater than the under-voltage protection point of business module, the output voltage of power supply also certainty greater than the under-voltage protection point of main control module.The magnitude of voltage of the output voltage of power supply is in case during less than the under-voltage protection point of business module, business module disconnects the connected power supply circuits of power supply voluntarily, thus the operate as normal of assurance main control module.
Power-supply management system in the communication equipment that the embodiment of the invention provided comprises main control module 1, wherein:
Method for managing power supply has identical technical characterictic in power-supply management system in the communication equipment that present embodiment of the present invention provided and the communication equipment that the invention described above present embodiment is provided, so also can realize identical technique effect, and then solve identical technical problem, so no longer repeat to set forth herein.
In addition, because the control of using main control module 1 to realize in the present embodiment to business module 2, can not only make full use of the main control module 1 (for example main control card) in the communication equipment, and the technical scheme that helps to use present embodiment to provide is transformed to existing communication equipment.
In the present embodiment, power supply 3 comprises signal generating module 30, wherein:
Signal generating module 30, be used in the total power consumption of main control module 1 and business module 2 during greater than a certain predetermined POL, send first alarm signal, and in the total power consumption of main control module 1 and business module 2 during less than predetermined POL, stop to send first alarm signal, the performance number of predetermined POL is less than maximum rated power output;
Signal generating module 30, when also being used for total power consumption at main control module 1 and business module 2 greater than maximum rated power output, send second alarm signal, during less than maximum rated power output, stop to send second alarm signal in the total power consumption of main control module 1 and business module 2;
Predetermined POL can artificially be set, for example can be set at size between maximum rated power output 60%～90% between some values, the effect of first alarm signal be to determine the total power consumption of main control module 1 and business module 2 reopen when being reduced to what degree before pent power consumption module.If what the total power consumption of main control module 1 and business module 2 reduced is not too low, pent power consumption module before reopening this moment so, the total power consumption of main control module 1 and business module 2 can rise in the relatively shorter time, though if cause main control module 1 or the excessive enchancement factor of business module 2 power consumptions can disappear after a time, but this moment, this enchancement factor still also exists, and is disconnected the main control module 1 of power supply and the effect that business module 2 recovers operate as normal before that does not just have and makes.
In the present embodiment, main control module 1, also be used for the continuous number of repetition that record traffic module 2 is closed and is opened, and after number of times reaches predefined numerical value, when the total power consumption of main control module 1 and business module 2 still surpasses maximum rated power output, close at least one business module 2, the total power consumption that makes main control module 1 and business module 2 is sent the ALM signal simultaneously less than predetermined POL.
Close repeating, after the number of times of unlatching business module 2 operations reaches predefined number of times, when the total power consumption of main control module 1 and business module 2 still can surpass maximum rated power output, usually cause main control module 1 or the excessive enchancement factor of business module 2 power consumptions to need operating personnel to judge as the case may be, and then take measures to eliminate enchancement factor, undying repeating closed, open business module 2 operations and can't overcome such problem, for example: when 2 short circuits of partial service module, restart business module 2, can't eliminate short circuit problem.
In the present embodiment, power supply 3 also comprises:
And/or thermal protection circuit 32 is used for when the temperature of power supply 3 surpasses predefined temperature value, and the output voltage of power supply 3 reduces;
When the maximum overload capacity that the total power consumption of main control module 1 and business module 2 can bear greater than power supply 3; the output current of power supply 3 is very high; at this moment; can judge the power output of power supply 3 is whether the total power consumption of main control module 1 and business module 2 has reached the maximum overload capacity that can bear by the mode of gathering electric current; when the output voltage that reduces power supply 3; make the magnitude of voltage of output voltage of power supply 3 greater than the under-voltage protection point of main control module 1; and during less than the under-voltage protection point of business module 2; can keep main control module 1 work closing when thereby business module 2 deducts business module 2 power consumptions.
Owing to be mounted with more software program usually in the main control module 1, in a single day main control module 1 is closed to restart and can be expended the more time, so such scheme helps to reduce the total boot time of communication equipment, simultaneously, when monitoring by main control module 1 or controlling business module 2, keep the operating state of main control module 1, can be by 1 pair of business module 2 of main control module and then related the closing or opening operation of above-mentioned present embodiment, and then guarantee that communication equipment has self-healing function.
When power supply 3 temperature are too high, can not cause power supply 3 interior electronic devices to burn out if do not reduce the total power consumption of main control module 1 and business module 2 immediately, so technique scheme can used 1 pair of business module 2 of main control module and then related the closing or opening operation of above-mentioned present embodiment, and then guarantee that communication equipment has under the situation of self-healing function, reduces the total power consumption of main control module 1 and business module 2 to greatest extent.
When main control module 1 detects all business modules 2 and cuts off the power supply voluntarily, at this moment, business module 2 existing problems normally can't self-healing solve (for example business module short circuit), so this moment, main control module 1 sends the ALM signal, waits for that operating personnel check and get rid of the problem of business module 2 existence.Business module 2 can be realized cutting off the power supply voluntarily by the mode of the business module mains switch 6 between automatic disconnection itself and the power supply 3 in the present embodiment.Main control module 1 is realized cutting off the power supply voluntarily by the mode of the main control module mains switch 5 between automatic disconnection itself and the power supply 3.
In the present embodiment, main control module 1, after also being used to close business module 2 at least twice, identification is closed before the business module 2 at every turn, power consumption is all greater than the business module 2 pairing address or the identification codes of rated power separately, make with address or identification code corresponding service module 2 to be in closed condition, and always when closing according to the priority of predefined power consumption module or opening business module 2, the priority of address or identification code corresponding service module 2 is considered as not existing.
After closing business module 2 at least twice, main control module 1 is closed before the business module 2 at every turn, power consumption is all greater than the business module 2 of rated power separately, the excessive reason of its power consumption is normally because internal fault, for example short circuit, can't make it recover operate as normal by the mode that restarts, so need identify these business module that has fault 2 pairing address or identification codes, and make it be in closed condition always, avoid existing 2 pairs of whole influences that the communication equipment of business module 2, main control module 1 is set of business module of fault.Main control module 1 is closed or when opening business module 2 at every turn, the priority of address or identification code corresponding service module 2 is considered as not existing, can avoid priority and in the process that opens or closes, can close normally or start, do not had the influence of the business module 2 of fault with respect to the inconsistent business module 2 of the priority of the business module 2 that has fault.
Identification exists the business module 2 pairing addresses of fault or the method for identification code can have multiple in the present embodiment, for example: can on business module 2, testing circuit be set, when the electric current that testing circuit detects incoming traffic module 2 surpasses the normal electrical flow valuve, send fault-signal, can judge that there is fault in which business module 2 according to fault-signal then, also can on main control module 1, testing circuit be set, directly judge which business module 2 when the electric current that testing circuit detects incoming traffic module 2 surpasses the normal electrical flow valuve and have fault.Because being an analog quantity, electric current is interfered easily when in communication equipment, transmitting, so be preferably in the present embodiment on each business module 2 testing circuit be set, when the electric current that the testing circuit on each business module 2 detects its pairing business module 2 of input surpasses the normal electrical flow valuve, send the fault-signal of digital signals format.
