Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] figure 1 It is a flowchart of the detection method proposed by the present invention. Such as figure 1 As shown, the single board fault detection method proposed by the present invention comprises the following steps:

[0017] Step 1. Set a heartbeat signal register on the board, and power on the board to run;

[0018] Step 2. Alternately write specific heartbeat values ​​into the heartbeat signal register with a certain cycle;

[0019] Step 3, FPGA reads the value in the heartbeat signal register, and outputs the read heartbeat signal to the detection bus;

[0020] Step 4: Determine whether the software is running normally. Here you can judge whether the software is running normally by whether the dog feeding cycle exceeds the specified time. If yes, continue, otherwise, write the abnormal heartbeat value into the heartbeat signa...

Abstract

This invention discloses a method for testing errors of a single board including: 1, setting a heartbeat signal register on the board and operating on it on line, 2, writing specific heartbeat values alternatively in the register in a period of time, 3, FPGA fetches the heartbeat values and outputs the heartbeat signals to a test bus, 4, judging if the software works normally, if so, the work is continued, otherwise, it writes in abnormal heartbeat value or stops writing the value in the register to execute step 7, 5, carrying out writing and reading operation to the register in a main service chip and comparing if the values are consistent to judge if said chip works normally, 6, if so, the work is continued, otherwise, it writes the abnormal value or stops writing the value in the register, 7, judging if the signal is all right, if so, it returns to step 2, otherwise, the error of the single board is output.

Description

technical field [0001] The invention relates to a real-time fault detection method when a single board is running, belonging to the field of communication control. Background technique [0002] For equipment boards with high reliability requirements, it is necessary to respond quickly to board failures, manually replace the faulty board or activate the automatic protection switching mechanism to switch the services of the faulty board to the protection board. At this time, the fault detection of the single board is particularly important. Single-board fault detection refers to checking the running status of the software and hardware of the single-board through some method or external tools to determine whether the single-board is faulty. Currently, the most commonly used method for single-board fault detection is the indirect detection method. The indirect detection method mainly monitors the services carried by the single board, and checks whether the single board is fault...
