Equipment power-on detection method and device with protection function

Abstract

The invention discloses an equipment power-on detection method and device with a protection function. The method comprises the following steps: after equipment is power-on, starting a watchdog in a logic processing module; initializing equipment monitoring software of an MCU (micro control unit) to take over the watchdog; closing a service data path of a peripheral module connected with the logic processing module; and triggering the MCU to configure modules which are to be configured and connected with the MCU one by one, and when each module to be configured is configured successfully, opening the service data path of the peripheral module to enter into a normal operating state. By using the method and device disclosed by the invention, through hardware resources of equipment, and with the aid of a power-on flow of the equipment, a self-testing method with a protection function is embedded for protection to prevent abnormal damages after the specific modules are power-on and before the specific modules run normally, thereby effectively prolonging the normal operating time of the equipment.

Description

technical field [0001] The invention relates to a power-on configuration startup technology of communication equipment, in particular to a device power-on detection method and device with a protection function. Background technique [0002] Femto home base station is able to provide mobile communication capabilities inside the residence at the maximum data rate, and does not require the installation of micro-cell nodes. Femto directly faces business and home customers, and puts forward higher requirements for product experience: lightweight, low energy consumption, high reliability, stability, large capacity, etc., making the hardware design more streamlined and pursuing the maximum capacity, and a large number of new technologies Such as high-speed data transmission, there must be higher requirements for each link of the product, especially the startup process such as product power-on configuration, module protection, and inter-module coordination. For example: whether th...

Problems solved by technology

[0003] However, the working environment inside the board is chaotic and uncontrollable after power-on and before normal operation. Some modules in the board, such as CPLD (Complex Programmable Logic Device, complex programmable logic device) processing module, watchdog processing module, CPU processing modules, soft switch modules, peripheral function modules, etc. are easily damaged, which shortens the working life of these devices
