First, second field effect transistor is at the same level to link to each other, and its default conditions are for closing; When first field effect transistor of stand-by power supply control circuit was closed, the stand-by power supply control circuit was in off-state with stand-by power supply; When first, second field effect transistor of stand-by power supply control circuit was all opened, the stand-by power supply control circuit was in access state with stand-by power supply; Voltage detecting circuit: detect the access state of the primary power cource of its place veneer in real time, when the primary power cource that detects this veneer is in off-state, second field effect transistor is opened.

Mbus module can be realized by the field effect transistor of the low equivalent resistance in the stand-by power supply control circuit the control of stand-by power supply.As shown in Figure 5: the stand-by power supply that veneer is obtained from backboard, guide in the veneer load by two field effect transistor.The design of two field effect transistor has novelty and unique effect, can realize the Based Intelligent Control of stand-by power supply by field effect transistor to the control strategy of stand-by power supply, and concrete Based Intelligent Control property list is present:

1. can prevent that electric current pours in down a chimney in the circuit.Generally speaking; a parasitic diode is arranged between the D utmost point of field effect transistor and the S utmost point; this diode is the protection field effect transistor; but in the power circuit of insulation request is arranged; this parasitic diode can cause pouring in down a chimney of reverse current, and system is caused potential safety hazard, and this programme uses two field effect transistor homopolarity series connection; such two equivalent diodes can cut off the loop of pouring in down a chimney, and guarantee system safety from designing.

2. use field effect transistor to replace diode to do the isolation of power supply.The equivalent resistance of field effect transistor is far smaller than diode, and it is very little to the droop loss that power supply causes, and can guarantee the performance of circuit under the nowadays big current conditions.Field effect transistor has the control utmost point of a controllable power conducting, in the integrated circuit design, has greatly improved the flexibility and the practicality of circuit.

3. by using two controlled field effect transistor of difference to realize stand-by power supply safety, intelligentized switching.First field effect transistor is opened or is turn-offed by mbus module control among Fig. 5; Second field effect transistor is opened or is turn-offed by the electric voltage observation circuit control of stand-by power supply control circuit.Second field effect transistor is switched by the electric voltage observation circuit control of stand-by power supply control circuit, is characterized in that switch speed is exceedingly fast, and the time that power supply switches, veneer did not reset in the time of can guaranteeing the power supply switching in delicate level, and business is not interrupted.

Control to first field effect transistor is divided initiation and by mbus module, can be guaranteed the intellectuality of The whole control system by the communication apparatus power control part.Under being used of two field effect transistor, intelligent characteristic is embodied in: during Board Power up, closed by first field effect transistor of power control unit control, the state that initially powers in system like this, can guarantee that veneer power supply is the main power source power supply by this plate, and can not take place because the instability of powered on moment power supply and veneer that nondeterministic statement causes all switch to the phenomenon of stand-by power supply work.After system's power-up state settles out, just initiate the open command of stand-by power supply, the passage of opening power backup by power control unit.After system was stable, if protection automatically or artificial power off command take place certain veneer, power control system at first can turn-off this veneer main power source, simultaneously, only cuts off this veneer first field effect transistor as shown in FIG., to cut off the stand-by power supply of this veneer.Need so promptly can guarantee the power-down state of outage veneer, not influence the power protection state of other veneer again.

When certain veneer hot plug, field effect transistor shown in Fig. 5 is designed to give tacit consent to off state, each one-board power supply module is also given tacit consent to off-position, and like this in the process of veneer hot plug, what cause because immediate current is big with regard to veneer connector can not take place burns or problem such as life-span reduction.After the veneer insertion system is stable, mbus module on its place veneer divide to be initiated the powering on request of this veneer to the communication apparatus power control part, and communication apparatus power control part branch sends power information that this veneer primary power cource power on from mbus module by main mbus module and CAN bus on this veneer.The primary power cource control circuit that should control this veneer according to this power information from mbus module is in access state with the primary power cource of this veneer, the primary power cource of this veneer insert stable after, the communication apparatus power control part divides by main mbus module and CAN bus send this veneer by the power information with power supply electrifying from mbus module on this veneer.The stand-by power supply control circuit of controlling this veneer according to this power information from mbus module of this veneer is in access state with the stand-by power supply of this veneer.

This cover control strategy of stand-by power supply control circuit can guarantee to the full extent that communication apparatus works safely and steadly.

The logic diagram of the power supply of mbus module and control veneer primary power cource as shown in Figure 6.

In Fig. 6, comprise and close the road diode, mbus module main body circuit, d type flip flop, primary power cource control circuit, one-board power supply module.

Closing the road diode closes the road with the active and standby two-way power supply of mbus module and offers mbus module.Mbus module main body circuit is initiated relevant active and standby control command with power supply.D type flip flop is under the effective situation of the clock of mbus module, and the control command of the primary power cource that the mbus module transmission is next transfers to the primary power cource control circuit.Transfer to the power module of veneer after the primary power cource control circuit is isolated this control command light lotus root, the one-board power supply module is with primary power cource access/disconnection.

Because mbus module is participated in the control of single board main/standby with power supply directly, abnormal power-down can not take place in veneer when unusual in order to guarantee to occur in mbus module operation, and the power supply of mbus module main body circuit and d type flip flop resupplies mbus module main body circuit and d type flip flop after closing the road by the active and standby two-way power supply of mbus module and host's plate power supply.Can find out obviously that from Fig. 6 if the mbus module power down, the primary power cource control signal of mbus module output can be locked in current state, does not influence the operate as normal of its place veneer.

The schematic diagram of mbus module centrally connected power supply as shown in Figure 7.

Because mbus module participates in the direct control of communications device single board active/standby with power supply, so the reliability of mbus module self power supply should be very high.The mode of centrally connected power supply is adopted in power supply to mbus module, carries out mutual Hot Spare by two block power supply veneers.The two-way 5V power supply of mbus module closes the road in mbus module, to guarantee the reliability of mbus module power supply.

The present invention carries out the 1+1 hot backup except that the power supply to mbus module, the power unit circuit of directly controlling its place veneer in the mbus module triple power supply backups have been carried out, the power supply that is about to 1+1 hot backup closes Lu Houzai with the power supply of its place veneer again and offers in the mbus module the directly power control part parallel circuit of its place one-board power supply of control, with guarantee mbus module no matter be occur power issue also be non-power issue can make its place veneer not down.Above-mentioned non-power issue comprises that the insurance of power supply is opened circuit on the mbus module, mbus module top component failure etc.These non-power issues can cause the d type flip flop normal running conditions on the mbus module to change, thereby the power supply supply of mbus module place veneer is gone wrong.The power control part parallel circuit of directly controlling its place one-board power supply in the mbus module is carried out triple power supply backups can guarantee directly more reliable, the stable work of power unit circuit of its place veneer of control in the mbus module.

The present invention prevents that veneer from being hindered for some reason by thereon mbus module and can not control the active and standby power supply of using of this veneer, each single board main/standby is controlled flexibly with power supply, also design primary power cource and forced to insert part, when the mbus module of certain veneer breaks down, force to insert part by primary power cource the primary power cource of veneer is forced to insert veneer.Primary power cource is forced to insert part and can be realized by switch or wire jumper.

Based on communication apparatus power-supply management system of the present invention, the present invention also provides a kind of implementation method of communication apparatus power management, specifically may further comprise the steps:

When communication apparatus power control part branch receive that webmaster side power control part divides that transmission comes with the active and standby power information that switches with power supply of corresponding veneer the time, communication apparatus power control part branch transfers to the main mbus module of its place veneer with this power information, main mbus module with this power information by the CAN bus transfer to the corresponding veneer from mbus module.On this veneer receive this power information from mbus module after, issue the control command of primary power cource access/disconnection according to this power information to the primary power cource control circuit by primary power cource control submodule, the primary power cource control circuit is controlled the power module of this veneer with primary power cource access/disconnection.The submodule of stand-by power supply control simultaneously issues the control command of stand-by power supply access/disconnection to the stand-by power supply control circuit according to this power information, when control command is the stand-by power supply access, the stand-by power supply control circuit is opened first field effect transistor, when control command was the stand-by power supply disconnection, the stand-by power supply control circuit cut out first field effect transistor.After the primary power cource that the voltage detecting circuit of stand-by power supply control circuit monitors this veneer lost efficacy, control second field effect transistor and open stand-by power supply is in power supply state.Voltage detecting circuit with the active and standby information of switching with power supply report its place veneer from mbus module.

The communication apparatus power control part divides the main backup power source voltage of monitoring communication apparatus in real time, when the primary power cource that monitors communication apparatus lost efficacy, on each veneer, issue the power information that primary power cource switches to stand-by power supply by main mbus module, CAN bus from mbus module, control the active/standby power control circuit of using of its place veneer respectively from mbus module on each veneer, primary power cource is in dissengaged positions, stand-by power supply is in power supply state.When the primary power cource that monitors communication apparatus is become when effective by inefficacy, on each veneer, issue the power information that stand-by power supply switches to primary power cource by main mbus module, CAN bus from mbus module, control the active/standby power control circuit of using of its place veneer respectively from mbus module on each veneer, primary power cource is in access state, stand-by power supply is in off-state.

If the primary power cource voltage of communication apparatus lost efficacy; when communication apparatus being powered by backup power source voltage; meetings such as stand-by power supply such as storage battery reduce the supply power voltage of communication apparatus because discharge for a long time; the communication apparatus power control part divides when the access supply voltage that monitors communication apparatus is lower than predetermined supply voltage; by main mbus module; the CAN bus issues active and standby power information with power cut-off to each veneer of communication apparatus from mbus module; the primary power cource control submodule of each veneer from mbus module; stand-by power supply control submodule is controlled the primary power cource control circuit respectively; the stand-by power supply control circuit is with the active and standby power cut-off of using of each veneer, with the protection stand-by power supply.

When the veneer hot plug of communication apparatus, be set to close to cut off the stand-by power supply of this veneer from first field effect transistor of mbus module stand-by power supply control circuit, by the power module on the primary power cource control circuit control veneer primary power cource is disconnected simultaneously, like this when veneer carries out hot plug, all be in off-position owing to active and standby with power supply, so avoided sparking or latch phenomenon.

After the insertion of veneer heat is stable, this veneer divides the request of powering on that sends this veneer from the request that the powers on submodule of mbus module to the communication apparatus power control part, the request of powering on of this veneer is by the main mbus module of CAN bus transfer to communication apparatus power control part branch place veneer, main mbus module transfers to communication apparatus power control part branch with the request of powering on of this veneer, the communication apparatus power control part divides the power information that the primary power cource of this veneer is powered on according to the request of powering on of this veneer by main mbus module, the CAN bus transfer to this veneer from mbus module, issue the control command that primary power cource is powered from the primary power cource control submodule of mbus module according to this power information, the control power module is in access state with primary power cource.After primary power cource access power supply is stable, the power information that communication apparatus power control part branch powers on the stand-by power supply of this veneer by main mbus module, CAN bus transfer to this veneer from mbus module, issue the control command that stand-by power supply is powered from the stand-by power supply control submodule of mbus module according to this power information, first field effect transistor in the stand-by power supply control circuit is opened.

After if the request that the powers on submodule of the mbus module on the veneer sends the request of powering on, owing to reasons such as CAN bus or main mbus module or power control terminals, make the mbus module on this veneer not receive the power information of this next single board main/standby of communication apparatus power control part branch transmission in the given time with power supply electrifying, the present invention is in order to control the active and standby power supply of using of veneer flexibly, setting is not received active and standby power information with power supply electrifying in the given time from mbus module, issues the active and standby control command with power supply electrifying of this veneer respectively automatically.If owing to breaking down of this veneer from mbus module, can not issue active and standby control command with power supply electrifying, the present invention also provides by primary power cource and forces to insert the function that part is in the primary power cource of veneer as switch, wire jumper etc. the access power supply state.

When communication apparatus powered up, the communication apparatus power control part divided the veneer at place uncontrolled, at first powers on.The request that the powers on submodule solicited message that will power on from mbus module of each veneer transfers to communication apparatus power control part branch by CAN bus, main mbus module, the communication apparatus power control part divide according to predetermined electric sequence respectively with each single board main/standby with the power information of power supply electrifying by main mbus module and CAN bus transfer to each veneer from mbus module.

Predetermined electric sequence can be set at does not have the veneer of electric sequence to power on earlier, powers on after the veneer of electric sequence is arranged, and primary power cource powers on earlier, powers on behind the stand-by power supply.

The communication apparatus power control part divides the specific implementation method that realizes electric sequence control to be:

The communication apparatus power control part divides at first by main mbus module, CAN bus issue the power information that primary power cource powers on from mbus module on the veneer that does not have electric sequence, do not have electric sequence veneer issue the control command that primary power cource powers on from the primary power cource of mbus module control submodule according to this power information, by primary power cource control circuit control power module the primary power cource of its place veneer is in access state.

The communication apparatus power control part divides again asks to issue power information that primary power cource power on to each veneer that electric sequence is arranged from mbus module by main mbus module, CAN bus respectively according to powering on of the veneer that electric sequence is arranged.Have electric sequence each veneer issue the control command that primary power cource powers on from the primary power cource of mbus module control submodule according to this power information, by primary power cource control circuit control power module the primary power cource of its place veneer is in access state.

When the primary power cource of each veneer of communication apparatus power on stable after, the communication apparatus power control part divides by main mbus module, CAN bus send the power information that stand-by power supply powers on from mbus module on the veneer that does not have electric sequence, do not have the stand-by power supply control submodule from mbus module of the veneer of electric sequence to issue the control command that stand-by power supply powers on, control first field effect transistor of the stand-by power supply control circuit of its place veneer and open according to this power information.

The communication apparatus power control part divides by main mbus module, CAN bus send the power information that stand-by power supply powers on from mbus module on the veneer that electric sequence is arranged, there is the stand-by power supply control submodule from mbus module of the veneer of electric sequence to issue the control command that stand-by power supply is powered, controls first field effect transistor of the stand-by power supply control circuit of its place veneer and open according to this power information.

After communication apparatus powers up, if veneer send the request of powering on from mbus module, but this veneer does not receive the active and standby power information with power supply electrifying that the communication apparatus power control part divides transmission from mbus module, the controlling the active and standby of this veneer voluntarily from mbus module and power on respectively with power supply of this veneer in the given time.If owing to breaking down of this veneer from mbus module, can not issue active and standby control command with power supply electrifying, the present invention also provides by primary power cource and forces to insert the function that part is in the primary power cource of veneer as switch, wire jumper etc. the access power supply state.

Owing to make communication apparatus little to the impact of power supply to each single board main/standby of communication apparatus with the Based Intelligent Control of power supply electrifying, and active and standby successively powering on power supply avoided because the instability of powered on moment power supply and nondeterministic statement cause the phenomenon of each single board main/standby with the power supply switching at powered on moment.

When the mbus module of certain veneer knows that by the temperature sensor on this veneer the temperature of its place veneer surpasses the preset limit temperature, mbus module on this veneer passes through the CAN bus with the temperature warning information of this veneer, main mbus module transfers to communication apparatus power control part branch, the communication apparatus power control part divides according to temperature warning information uses this single board main/standby the power information of power cut-off by main mbus module, the CAN bus transfer is extremely accordingly from mbus module, should with power control circuit the active and standby of this its place veneer all be in off-position with power supply by active/standby respectively with power supply control submodule from the active/standby of mbus module, to avoid veneer because high temperature and scaling loss.

When the mbus module of certain veneer knows that by the voltage monitoring submodule access supply voltage of its place veneer surpasses predetermined high pressure or is lower than predetermined low pressure, mbus module on this veneer transfers to communication apparatus power control part branch with the voltage warning information of this veneer by CAN bus, main mbus module, and the communication apparatus power control part divides by the signal transmssion line between communication apparatus the voltage warning information of this veneer is transferred to webmaster side power control part branch.

When the network side power control part divided the power information of the outage manually issue certain veneer, the communication apparatus power control part divided according to the outage power information that receives and issues power information that primary power cource outage and stand-by power supply cut off the power supply to corresponding veneer from mbus module by main mbus module and CAN bus.The power module that the primary power cource control submodule from mbus module on the corresponding veneer is controlled its place veneer by the primary power cource control circuit is in off-state with primary power cource, stand-by power supply control submodule is controlled first field effect transistor of the stand-by power supply control circuit of its place veneer and is closed, to cut off the stand-by power supply of this veneer.
