Problems solved by technology

The reliability and correctness of data transmission are the prerequisites for the quality characteristics of reflective memory. Due to the high integration of reflective memory hardware and the transparency of the driver to users, fault detection and detection in the reflective memory stage are relatively lacking

Embodiment Construction

[0051] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0052] A single-node reflective memory and reflective memory network fault detection method, comprising the following steps:

[0053] Step 1. Single node reflective memory fault detection. Such as figure 1 Shown is a reflective memory single-node memory fault detection flow chart.

[0054] Such as figure 2 As shown, the reflective memory card has 128M or 256M SDRAM (Memory) on board, which is used to temporarily store the shared data of each reflective memory card in the network. Single-node reflective memory faults are mainly caused by memory faults. Therefore, detection of single-node reflective memory faults includes data line detection, address line detection, and physical storage component detection.

[0055] Step 1.1, data line detection. There are two kinds of errors in the data line connection, one is disconnected, and the other is shorted to each...

Abstract

The invention relates to a fault detection method for a single-node reflective memory and a reflective memory network, which is technically characterized in that specific data is written into a data line, the data in the data line is read out after data processing of the data line, and the data is compared with a set result; the data line, the address line and the physical storage component are detected so as to detect whether the single-node reflective memory has a fault or not; and whether a fault exists in the reflective memory network or not is detected through reflective memory network data transmission anomaly detection and reflective memory network node offline fault detection, rapid and simple single-node reflective memory fault and system reflective memory fault diagnosis is achieved, and the reliability of the reflective memory network can be improved.

Description

technical field [0001] The invention belongs to the technical field of reflective memory fault diagnosis, in particular to a fault detection method for single-node reflective memory and reflective memory network. Background technique [0002] Reflective memory network is a mature technology. After years of development, it is currently used in hardware-in-the-loop simulation, flight simulators, automatic monitoring systems, engine test benches, radio simulators, high-speed data acquisition, over-the-horizon radar, and high-speed data for ship navigation. It is widely used in transmission and other application fields. [0003] The unique hardware structure of reflective memory simplifies the real-time transmission of large amounts of data to the greatest extent. System designers do not need to understand the responsible data transmission process, only read and write locally, and the hardware automatically completes data synchronization with other nodes in the reflective memor...
