Embodiment 1

[0020] according to figure 1 , The present invention includes a single board, the single board includes an input power module 1, a CPU, a reset module 2, etc., wherein the input power module 1 is connected to a multi-channel power chip 3, such as figure 1 As shown, the multi-channel power chip 3 outputs Vout1, Vout2...Voutn, and the multi-channel power chip 3 is the CPU, the reset module 2 and various functional modules in the single board, such as the voice codec module 5, the memory 6 and the field programmable gate. The array 7 provides power, and 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 chip 3.

[0021] Such as figure 1 As shown, the power control unit 4 includes a signal detection & acquisition module 41 and a signal processing module 42. The signal detection & acquisition module 41 completes the detection of the output st...

Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is that: in this embodiment, the power chip 3 is also connected in series with a metal oxide semiconductor switch, and the signal processing module 42 can directly control the metal oxide semiconductor switch when powering off. Perform control and complete the power-off operation.

[0031] As for other structures, principles, and control processes that are the same as 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 present invention relates to power supply equipment, in particular to a power control method and system of a communication system. Background technique [0002] In a communication system, when multiple boards are inserted into the same frame to work simultaneously, the power is often relatively high. When one of the power supply chips in the multi-channel power supply provided by a single board fails, it is easy to cause damage or failure of the function module or core chip of the single board; when the function module of one of the single boards fails, the whole single board cannot work normally However, a single board may still consume power. Moreover, multiple boards share one or more sets of buses. When a single board fails, the power supply needs to be cut off in time to isolate the faulty board, so as not to interfere with other boards in the chassis. The board causes signal interference. Therefore, when the above-mentioned fault occurs, the fault...
