Description
Technical field
The present invention relates to being connected of motherboard and veneer in the telecommunication transmission equipment, disclose a kind of method and apparatus of controlling power supply sequence of single board especially.
Background technology
Communication system is made up of different subsystem frame, interpolation frame usually.Each interpolation frame all comprises a motherboard, at least one master control borad, one or more power supply and miscellaneous service veneer.Different veneers are linked to each other by motherboard usually, and power supply is offered the slot of each master control borad and each veneer place motherboard by power bus.
If system needs to change module in running, then need to consider the hot plug demand.Hot plug claims warm swap (Hot Swap again, Hot Insertion or Live Insertion), be meant a veneer is inserted in the system that is moving safely, perhaps from the system that is moving, extract safely, do not damage or damage and the veneer that inserts is not caused, system's power supply and system's operate as normal are not produced interfere with or compromise yet.
Veneer input great majority all have bigger filter capacitor, when one has put electric capacitive load veneer band and has been electrically interposed in motherboard, can produce bigger overshoot current and (or claim surge current, power-on impact current, Inrush Current), thereby cause that input voltage falls, phenomenons such as connector pin sparking, may cause interference, power connector contact erosion even cause other circuit resets, thereby need the rate of rise or the amplitude that a power interface circuit is controlled voltage or electric current at the input of circuit, to alleviate or to eliminate the harmful effect that hot plug when powering on (or system) may bring, Here it is our usually said power supply soft-start circuit.
The slow electric current that the opens when basic function of power supply soft-start circuit is the restriction Board Power up.Usually, the power supply soft-start circuit is provided with certain delay time at the Shi Douhui that powers on, the power supply shake that causes to eliminate the spring of connector pin or contact (promptly anti-shake, or claim to go to tremble or disappear to tremble, Debouncing).The power supply soft-start circuit is divided into discrete component circuit and integrated control chip circuit two classes of special-purpose hot plug according to the integrated level of components and parts, according to the veneer input voltage can be divided into again-48V power supply and low pressure (as ± 5V, 3.3V etc.) two class circuit.
Soft-start circuit is normally realized variable resistor by the power MOS pipe gate source voltage of connecting in the control circuit, thus the input voltage and the electric current of the level load of control back.Usually hope will be delayed and be opened Current Control (thereby slow open time also corresponding longer) in small range.
Each veneer in the communication system devices, master control borad also need to control the order of its each equipment veneer power-on and power-off in the slow startup of needs, its reason is:
1, when the power consumption of telecommunication apparatus is very big, be 48V such as voltage, power consumption is during greater than 6000W, if when device power, all veneers all power on simultaneously, and the impulse current of moment can surpass 160A so.Operating current rises in the short time about 160A at the utmost point from 0A, and this rush of current all can cause bigger injury to system power supply, power connector and distribution system, influences its reliability.
2, veneer is in hot plug process, and the contact pin of power connector has not also contacted veneer fully just to begin to power on, and contact resistance is bigger.Because veneer power is very big, impulse current is to there being very big influence in useful life of veneer connector.This impact strength can be reduced though on veneer, increase the power supply soft-start circuit, impact damage can not be avoided fully.
3, the veneer of telecommunication apparatus is all very expensive, and it is just very big the loss that the damage of single plate hardware brings to occur.And veneer (for example the temperature of Jian Ceing surpasses situations such as fatal thresholding, electric voltage exception) when operation irregularity occurring if can in time just can avoid the upgrading of fault to electricity under the veneer, thereby plays the effect of protecting hardware.
Fig. 1 is a control power supply sequence of single board module map in the prior art.As shown in Figure 1, telecommunication apparatus generally include the polylith veneer (veneer 1, veneer 2 ... ... veneer n), all comprise a power module and a power-on and power-off control module on the every veneer.Prior art is for going to control power-on and power-off control module on the veneer by a special cover control bus transmission of control signals on the motherboard of telecommunication apparatus, realize the shutoff of power module or open, thereby control the power-on and power-off order of each one-board power supply.Control independent circuit and the special software of this cover bus requirements one cover and go to control the power-on and power-off control module.
By above-mentioned analysis as can be seen, prior art is in the system of control power supply sequence of single board, the power-on and power-off control module needs to use separately circuit kit, also need operating software to control by control bus, thereby increased the cost of telecommunication apparatus, but also owing to used software to bring the low problem of reliability.
