Method and apparatus for implementing base station power-down alarm by using interrupt

Abstract

The invention relates to a method and device for warning power-fail of base station by interrupting. After a power module tests the power-fail of base station, a signal of warning power-fail is outputted to a programmable logic device; the programmable logic device generates an interrupt source signal according to the signal of warning power-fail, and writes a value that stands for the signal of warning power-fail in a memory module; the interrupt source signal and another interrupt source signal carry out AND operation, and the result of the AND operation is transmitted to a processor to trigger the processor to interrupt; after the processor is triggered to interrupt, the memory module is inquired; after the value that stands for the signal of warning power-fail is inquired, the information of warning power-fail is transmitted to a controller of the base station. The invention warns power-fail of base station by interrupting; while improving the reliability, the application of the method of interrupting the processor with other interrupt source signal can save the interrupt resource of the processor, and can conveniently implement the function of warning power-fail of base station in the application that the interrupt resource of the processor is in stress.

Description

technical field [0001] The invention relates to a method and a device for a power-down alarm of a base station, in particular to a method and a device for reporting a power-down alarm of an outdoor micro base station by using interruption. Background technique [0002] In modern base station management, it is required to implement the function of power failure alarm, so as to distinguish whether the base station is a power failure failure or other line reasons causing communication failure. After the power module of the base station is powered off, it can output a power-down alarm signal before the output of the power module is completely cut off, and the timing advance is 100ms-300ms. The base station must reliably report the power failure warning message to the base station controller within this period of time. The current common implementation methods of the base station power-down alarm function are as follows. [0003] The first method is the query method. The proce...

However, the interrupt resources of the processor are limited, and the occasional power-down signal occupying an interrupt alone is obviously a waste of interrupt resources, especially when the interrupt resources are tight, using a separate interrupt to realize the power-down alarm of the base station will cause a waste of interrupt resources. more nervous
