Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention provide a kind of reliability, stability all relatively good, automaticity is high, and after breaking down, there is method for managing power supply in the communication equipment of self-healing ability and use the power-supply management system in the communication equipment of the method.
As shown in Figure 1, method for managing power supply in the communication equipment that the embodiment of the present invention provides, at least comprises the following steps:
A, use same power supply for the power supply of main control module and at least one business module;
B, exceed 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 can bear at arrival power supply, main control module is automatically within predetermined a period of time, close at least one business module, and during lower than maximum rated power output, reopen pent business module in the total power consumption of main control module and business module.
Because the present invention can for example, for example, exceed the maximum rated power output of power supply in the total power consumption of main control module (main control card) and business module (service card), and when the maximum overload capacity can bear at arrival power supply, automatically within predetermined a period of time, close at least one business module, and in the power output of power supply during lower than maximum rated power output, reopen pent business module, like this, when business module is due to random factor, cause the total power consumption of main control module and business module to exceed the maximum rated power output of power supply, and while being less than the maximum overload capacity that power supply can bear within predetermined a period of time, the present invention can be automatically within predetermined a period of time, close at least one business module, thereby the total power consumption that makes main control module and business module is at least reduced to the maximum rated power output that is less than power supply, and then can realize power supply and main control module is set and the protection of the communication equipment of business module,
Simultaneously, because the present invention can also be in the power output of power supply during at least lower than maximum rated power output, reopen pent business module, because in a lot of situations business module power consumption excessive be for example, due to random factor (: the client's of the immediate communication of switch access quantity is at a time too much temporary transient), and when business module and after power supply disconnection a period of time, cause the excessive enchancement factor of business module power consumption not exist, for example: after switch restarts, on it, the client's of the immediate communication of access quantity has reduced a lot, make the power consumption of the service card of switch can recover normal, now, reopen pent business module, making power supply is business module power supply again, the business module that is disconnected power supply before can making recovers normal work, automatically complete owing to being disconnected before the normally work that recovers of the business module of power supply, so after applying communication equipment of the present invention and having and break down, 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 poor to have solved in existing communication equipment use procedure reliability, the technical problem that automaticity is lower.
Power supply in the present invention can bear large maximum overload capacity, in the time that facility communication system designs, the fault that may occur according to communication equipment (for example: after in power supply, power module part breaks down or extracts, power supply power output is less than equipment real work power consumption), analysis meter calculates power supply maximum overload capacity (being greater than the rated power of power supply), make power supply exceed the maximum rated power output of power supply, and before the maximum overload capacity can bear at arrival power supply, 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) specifically how much can be first obtains according to the calculation of parameter of electronic device that forms main control module and business module the maximum power dissipation that main control module and business module can bear, and then selects or design can be born the power supply of maximum power dissipation within this predetermined a period of time according to maximum power dissipation.
As shown in Figure 2, in the present embodiment, step B specifically comprises the following steps:
B1, in the time that the total power consumption of main control module and business module is greater than a certain predetermined POL, power supply sends the first alarm signal to main control module, and in the time that the total power consumption of main control module and business module is less than predetermined POL, stop sending the first alarm signal, the performance number of predetermined POL is less than maximum rated power output;
B2, in the time that the total power consumption of main control module and business module is greater than maximum rated power output, power supply sends the second alarm signal to main control module, in the time that the total power consumption of main control module and business module is less than maximum rated power output, power supply stops sending the second alarm signal;
B3, receive after the second alarm signal at main control module, close at least one business module, make the total power consumption of main control module and business module be less than predetermined POL, and do not receiving the first alarm signal, while not receiving the second alarm signal yet, pent power consumption module before opening.
Predetermined POL can artificially be set, for example can be set as size between maximum rated power output 60%～90% between some values, the effect of the first alarm signal be to determine the total power consumption of main control module and business module when being reduced to what degree, reopen 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 so now reopening, the total power consumption of main control module and business module can rise within the shorter time, although if cause main control module or the excessive enchancement factor of business module power consumption can disappear after a time, but now, this enchancement factor still also exists, and that main control module and business module that is disconnected power supply before just not having and making recovers the effect of normal work.
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 reach after predefined numerical value at the number of times repeating continuously, when the total power consumption of main control module and business module still exceedes maximum rated power output, main control module is closed at least one business module, make the total power consumption of main control module and business module be less than predetermined POL, send ALM signal simultaneously.
The object of repeated execution of steps B is, in the time 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 normal work, has further strengthened the reliability of the communication equipment that main control module and business module are set.
Reach after predefined number of times at the number of times of repeated execution of steps B, when the total power consumption of main control module and business module still can exceed maximum rated power output, conventionally 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 cannot overcome such problem, for example: in the time of partial service module short circuit, restart business module, cannot eliminate short circuit problem.
The mode of sending ALM signal in the present embodiment can have multiple, for example: can adopt sounding, luminous mode, also 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, first close the power consumption module that priority is lower, until the total power consumption of main control module and business module is 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, first open the power consumption module that priority is higher, until the total power consumption of main control module and business module is greater than predetermined POL.
According to priority order from low to high, first close the power consumption module that priority is lower; According to priority order from high to low, first open power consumption module that priority is higher and can guarantee that the business module that priority is higher works the longer time all the time, and then guarantee that prior function can maintain the longer time.Certainly it can be also random, in the present embodiment, closing or open power consumption module.
As shown in Figure 4, in the present embodiment, further comprising the steps of:
D, in the time that the total power consumption of main control module and business module exceedes the maximum overload capacity that power supply can bear, power supply enters overcurrent protection, its output voltage reduces;
E, in the time that the magnitude of voltage of the output voltage of power supply is less than the under-voltage protection point of predefined business module, all business modules disconnect the connected power supply circuits of power supply automatically;
F, main control module detect that all business modules voluntarily when power-off, send ALM signal.
In the time that the total power consumption of main control module and business module is greater than the maximum overload capacity that power supply can bear, the output current of power supply is very high, now, 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 can bear by gathering the mode of electric current, when reducing the output voltage of power supply, make the magnitude of voltage of the output voltage of power supply be greater than the under-voltage protection point of main control module, and while being less than the under-voltage protection point of business module, can be closing in thereby business module deducts business module power consumption, keep main control module work.
Owing to being conventionally mounted with more software program in main control module, once closing to restart, main control module can expend the more time, so only close business module in such scheme, the method that maintains main control module work contributes to reduce the total boot time of communication equipment, simultaneously, when monitoring by main control module or when service control module, maintain the operating state of main control module, can carry out related the closing or opening operation of above-mentioned the present embodiment to business module by main control module, and then guarantee that communication equipment has self-healing function.
In the present embodiment, open the method for business module, can also comprise the following steps:
Close after business module at least twice, before identification is closed business module at every turn, power consumption is all greater than the corresponding address of business module or the identification code of rated power separately;
Make the business module corresponding with address or identification code always in closed condition, and while opening pent business module, the priority of address or business module corresponding to identification code is considered as not existing.
Close after business module at least twice, before closing 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 due to internal fault, for example short circuit, cannot make it recover normal work by the mode restarting, so need to identify these corresponding address of business module that has fault or identification codes, and make it always in closed condition, the impact of the business module of avoiding existing fault on the whole communication equipment that business module, main control module are set.When closing or opening business module, the priority of the business module that the address that above-mentioned steps is recorded or identification code are corresponding is considered as not existing, can avoid priority and can close normally or start in the process opening or closing with respect to the inconsistent business module of priority of the business module that has fault, do not had the impact of the business module of fault.
In the present embodiment, identification exists the corresponding address of business module of fault or the method for identification code can have multiple, for example: testing circuit can be set on business module, testing circuit detects when the electric current of incoming traffic module exceedes normal electrical flow valuve, send fault-signal, then can judge which business module exists fault according to fault-signal.
As shown in Figure 4, in the present embodiment, further comprising the steps of:
G, in the time that the temperature of power supply exceedes predefined temperature, power supply enters overtemperature protection, its output voltage reduces;
H, in the time that the magnitude of voltage of the output voltage of power supply is less than the under-voltage protection point of predefined business module, all business modules disconnect the connected power supply circuits of power supply automatically;
I, main control module detect that all business modules voluntarily when power-off, send ALM signal.
When power supply temperature is too high, can cause electronic device in power supply to burn out if do not reduce immediately the total power consumption of main control module and business module, so technique scheme can be in the time that the magnitude of voltage of the output voltage of power supply be less than the under-voltage protection point of predefined business module, all business modules disconnect the connected power supply circuits of power supply automatically, thereby reduce the total power consumption of main control module and business module; And then the safety of the each building block of assurance communication equipment.
When main control module detects that all business modules are voluntarily when power-off, now, the existing problem of business module normally cannot self-healing solve (for example business module short circuit), so now, main control module sends 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, so when the output voltage of power supply is greater than the under-voltage protection point of business module, the output voltage of power supply also must be greater than the under-voltage protection point of main control module.The magnitude of voltage of the output voltage of power supply is once the under-voltage protection point that is less than business module, and business module disconnects the connected power supply circuits of power supply voluntarily, thereby guarantees the normal work of main control module.
Power-supply management system in the communication equipment that the embodiment of the present invention provides, comprises main control module 1, wherein:
In the communication equipment that power-supply management system in the communication equipment that the present embodiment of the present invention provides provides with the invention described above the present embodiment, method for managing power supply has identical technical characterictic, so also can realize identical technique effect, and then solve identical technical problem, so no longer repeat to set forth herein.
In addition, realize the control to business module 2 owing to using main control module 1 in the present embodiment, can not only make full use of the main control module 1 (for example main control card) in communication equipment, and contribute to use the technical scheme that the present embodiment provides to transform existing communication equipment.
In the present embodiment, power supply 3 comprises signal generating module 30, wherein:
Signal generating module 30, for in the time that the total power consumption of main control module 1 and business module 2 is greater than a certain predetermined POL, send the first alarm signal, and in the time that the total power consumption of main control module 1 and business module 2 is less than predetermined POL, stop sending the first alarm signal, the performance number of predetermined POL is less than maximum rated power output;
Signal generating module 30, also in the time that the total power consumption of main control module 1 and business module 2 is greater than maximum rated power output, send the second alarm signal, in the time that the total power consumption of main control module 1 and business module 2 is less than maximum rated power output, stop sending the second alarm signal;
Predetermined POL can artificially be set, for example can be set as size between maximum rated power output 60%～90% between some values, the effect of the first alarm signal be to determine the total power consumption of main control module 1 and business module 2 when being reduced to what degree, reopen 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 so now reopening, the total power consumption of main control module 1 and business module 2 can rise within the shorter time, although if cause main control module 1 or the excessive enchancement factor of business module 2 power consumptions can disappear after a time, but now, this enchancement factor still also exists, and that main control module 1 and business module 2 that is disconnected power supply before just not having and making recovers the effect of normal work.
In the present embodiment, main control module 1, the continuous number of repetition that is also closed and is opened for record traffic module 2, and reach after predefined numerical value at number of times, in the time that the total power consumption of main control module 1 and business module 2 still exceedes maximum rated power output, close at least one business module 2, make the total power consumption of main control module 1 and business module 2 be less than predetermined POL, send ALM signal simultaneously.
Close repeating, the number of times that unlatching business module 2 operates reaches after predefined number of times, when the total power consumption of main control module 1 and business module 2 still can exceed maximum rated power output, conventionally 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 cannot overcome such problem, for example: in the time of 2 short circuit of partial service module, restart business module 2, cannot eliminate short circuit problem.
In the present embodiment, power supply 3 also comprises:
Circuit overcurrent protection 31, when be greater than the maximum overload capacity that power supply 3 can bear in the total power consumption of main control module 1 and business module 2, the output voltage of power supply 3 reduces;
And/or, thermal protection circuit 32, in the time that the temperature of power supply 3 exceedes predefined temperature value, the output voltage of power supply 3 reduces;
In the time that the total power consumption of main control module 1 and business module 2 is greater than the maximum overload capacity that power supply 3 can bear, the output current of power supply 3 is very high, now, 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 can bear by gathering the mode of electric current, when reducing the output voltage of power supply 3, make the magnitude of voltage of the output voltage of power supply 3 be greater than the under-voltage protection point of main control module 1, and while being less than the under-voltage protection point of business module 2, can be closing in thereby business module 2 deducts business module 2 power consumptions, keep main control module 1 to work.
Conventionally be mounted with more software program because main control module 1 is interior, once closing to restart, main control module 1 can expend the more time, so such scheme contributes to reduce the total boot time of communication equipment, simultaneously, when monitoring by main control module 1 or when service control module 2, maintain the operating state of main control module 1, can be by main control module 1 to business module 2 and then related the closing or opening operation of above-mentioned the present embodiment, and then guarantee that communication equipment has self-healing function.
When power supply 3 temperature are too high, can cause the interior electronic device of power supply 3 to burn out if do not reduce immediately the total power consumption of main control module 1 and business module 2, so technique scheme can used main control module 1 to business module 2 and then related the closing or opening operation of above-mentioned the present embodiment, and then guarantee that communication equipment has in 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 that all business modules 2 are voluntarily when power-off, now, the existing problem of business module 2 normally cannot self-healing solve (for example business module short circuit), so now, main control module 1 sends ALM signal, waits for that operating personnel check and get rid of the problem that business module 2 exists.In the present embodiment, business module 2 can be realized power-off voluntarily by the mode that automatically disconnects the business module mains switch 6 between itself and power supply 3.Main control module 1 is realized power-off voluntarily by the mode that automatically disconnects the main control module mains switch 5 between itself and power supply 3.
In the present embodiment, main control module 1, also for closing after business module 2 at least twice, before business module 2 is closed in identification at every turn, power consumption is all greater than the corresponding address of business module 2 or the identification code of rated power separately, make the business module corresponding with address or identification code 2 always in closed condition, and in the time closing or open business module 2 according to the priority of predefined power consumption module, the priority of address or business module 2 corresponding to identification code is considered as not existing.
Close after business module 2 at least twice, before main control module 1 is closed 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 due to internal fault, for example short circuit, cannot make it recover normal work by the mode restarting, so need to identify the corresponding address of business module 2 or identification code that these exist fault, and make it always in closed condition, the impact of the business module 2 of avoiding existing fault on the whole communication equipment that business module 2, main control module 1 are set.When main control module 1 is closed at every turn or opens business module 2, the priority of address or business module 2 corresponding to identification code is considered as not existing, can avoid priority and can close normally or start in the process opening or closing with respect to the inconsistent business module 2 of priority of the business module 2 that has fault, do not had the impact of the business module 2 of fault.
In the present embodiment, identification exists the corresponding address of business module 2 of fault or the method for identification code can have multiple, for example: can on business module 2, testing circuit be set, testing circuit detects when the electric current of incoming traffic module 2 exceedes normal electrical flow valuve, send fault-signal, then can judge which business module 2 exists fault according to fault-signal, also can on main control module 1, testing circuit be set, testing circuit detects that when the electric current of incoming traffic module 2 exceedes normal electrical flow valuve, directly judging which business module 2 exists fault.Because electric current is that an analog quantity is easily interfered while transmitting in communication equipment, so be preferably in the present embodiment on each business module 2 testing circuit be set, testing circuit on each business module 2 detects when the electric current of its corresponding business module 2 of input exceedes normal electrical flow valuve, sends the fault-signal of digital signals format.
