Embodiment 1

[0018] According to Fig. 1, the present invention includes a single board, which includes an input power module 1, a CPU and a reset module 2, etc., wherein the input power module 1 is connected to a multi-channel power supply chip 3, as shown in Fig. 1 , the multi-channel Power supply chip 3 outputs Vout1, Vout2...Voutn respectively, multi-channel power supply chip 3 provides power supply for CPU, reset module 2 and various functional modules in the single board, as voice codec module 5, memory 6 and field programmable gate array 7, The system also includes a power control unit 4, which completes the detection and collection of relevant information, and can perform corresponding power-off operations on the multi-channel power chips 3 .

[0019] As shown in Figure 1, power supply control unit 4 comprises signal detection & collection module 41 and signal processing module 42, wherein, signal detection & collection module 41 completes the detection of multi-way power supply chip...

Embodiment 2

[0028] The difference between this embodiment and Embodiment 1 is that in this embodiment, the power supply chip 3 is also connected in series with the metal oxide semiconductor switch, and the signal processing module 42 can directly control the metal oxide semiconductor switch as required when performing power-off control. Control and complete the power-off operation.

[0029] As for other structures, principles and control processes that are the same or similar to those described in Embodiment 1, they will not be repeated here.

Abstract

For multi-way power chip, the method detects its output state. According to output state of multi-way power chip, makes following operation: when the output state of multi-way power chip shows an un-recovering failure, making relevant powering off operation by controlling the state of enabling signal in power chip. In the procedure of powering off, the powering off operation can be made for all power chips in single board, or only be made for the power chip relating to failure; it can also be made by selecting the reset signal sent out from collection and reset module or by detecting signal from CPU, and based on the frequency of reset and detecting signal from CPU implementing relevant powering off operation.

Description

technical field [0001] The invention relates to power supply equipment, in particular to a communication system power supply control method and system. Background technique [0002] In a communication system, multiple boards are plugged into the same chassis and work at the same time, often with relatively high power. When one of the power chips in the multi-channel power supply provided by the single board fails, it is easy to cause damage or failure of the functional modules or core chips of the single board; when one of the functional modules of the single board fails, the entire single board cannot work normally However, the single board may still be consuming power. Moreover, multiple single boards share one or more sets of buses. Therefore, when the above-mentioned fault occurs, it is necessary to power off the faulty single board in time to save power or protect the entire single board to prevent it from being burned or key components from being damaged. In the prio...
