Below in conjunction with Fig. 3 to Fig. 6 the method that realizes the veneer power-on and power-off in the specific embodiment of the invention is described.As shown in Figure 5, the execution flow process of an embodiment of the method for realization Board Power up is as follows:
In the step 302, the pulse generating circuit 102 in the hot-swapping controller 100 generates and powers on enabling pulse and export to each professional groove position veneer.The enabling pulse that powers on that pulse generating circuit 102 generates can be that as shown in Figure 3 cycle is the pulse signal of 70 μ s, the duration t of high level in the single cycle
1=20 μ s, low level duration t in the single cycle
2=50 μ s.
Then in the step 304, pulse-detecting circuit 202 receptions on the veneer 200 are from the enabling pulse that powers on of pulse generating circuit 102.
In the step 306, pulse-detecting circuit 202 detects the received enabling pulse that powers on and whether meets default Board Power up condition.For example, it is as follows be in advance to set the condition that powers on that Board Power up need satisfy in pulse-detecting circuit 202:
A. the pulse high level duration must be between 18 μ s～22 μ s, and low duration must be between 48 μ s～52 μ s;
B. pulse count thinks that by 9 o'clock pulse is effective.
Therefore, pulse-detecting circuit 202 needs to detect the high level lasting time, low duration of the enabling pulse that powers on that receives and this pulse is counted, to judge whether meeting two conditions of above A, B simultaneously.In the various embodiments of the invention, high level lasting time that can paired pulses, low duration, umber of pulse are set different special parameters, or are only adopted the condition of wherein one or more parameters as Board Power up.

B '. pulse count thinks that by 9 o'clock pulse is effective.
Therefore, pulse-detecting circuit 202 needs to detect the high level lasting time, low duration of the following electric enabling pulse that receives and this pulse is counted, to judge whether meeting two conditions of above A ', B ' simultaneously.Equally, in the various embodiments of the invention, can provide concrete parameter setting according to the combination that designs above one or more requirements.
Then in the step 408, when above-mentioned down when electric condition all meets (the following electric enabling pulse that pulse generating circuit 102 sends is effective), pulse-detecting circuit 202 outputs effectively down electric signal give the back level circuit 204 that powers on.
In the step 410, the circuit 204 that powers on is carried out the following of veneer.
If pulse-detecting circuit 202 detects from the following electric enabling pulse of pulse generating circuit 102 outputs and do not meet above-mentioned electric condition down in the step 406, then in the step 412, veneer is not carried out down electricity, keeps existing state.
By said method, the present invention can use two kinds of different pulses to control powering on of veneer and following respectively.The pulse of adopting in the foregoing description is to be the certain pulses signal of 70 μ s in the cycle, the concrete waveform of obvious pulse used in the present invention is not limit by this, can be with the difference of design difference to some extent, as long as pulse generating circuit can produce, pulse-detecting circuit can detect.
