M/lj//i/ bus control and information recording method and system

Abstract

The invention provides an M / lj / / i / bus control and information recording method and system, and relates to the technical field of bus control and data processing. The system mainly comprises a host computer and a lower computer, wherein the host computer is a PC with USB interfaces and is installed with corresponding host computer software for receiving data displaying and storage and sending control instructions to the lower computer, and the lower computer has a 220V / 50Hz power conversion module, an M / lj / / i / (QBus) bus adaptor module, a signal transmit-receive unit and a data buffer memory unit. Equipment is mounted on the M / lj / / i / (QBus) bus through the bus adaptor module. Data reaches the signal transmit-receive unit through the bus adaptor module, is converted into digital signals, and sent to the host computer for display and storage after being converted through USB protocol via the data buffer memory unit. Control instructions are sent to the bus through a reverse process. The system is convenient for operation, and is widely used for fire control radar data analysis and test debugging. The system provides detailed analysis data for radar fault-finding.

Description

technical field [0001] The invention relates to the technical field of bus control and data processing, in particular to a MПИ bus control and information recording method and system. Background technique [0002] The Su-type aircraft uses the original Russian-made fire control radar, which communicates with other components of the radar through the MПИ (QBus) bus by the control center computer, exchanges data, and drives the radar to work. In order to study and analyze the working conditions of the radar, it is necessary to analyze and summarize the bus data generated during the working process of the radar, and at the same time, it is necessary to simulate the control computer to test the relevant control commands sent by the radar. Therefore, there is a need for a technology that can access the radar control bus without affecting the radar work, collect radar work data and simultaneously simulate the bus master to control the MПИ (QBus) bus to complete specific operations...

AI Technical Summary

Problems solved by technology

[0004] 1) Logic analyzers and oscilloscopes are expensive;

[0005] 2) Logic analyzers and oscilloscopes are bulky and heavy, and are not easy to carry in the field;

[0006] 3) The traditional method is prone to glitches during the data collection process, which greatly interferes with the data analysis and leads to inaccurate data analysis;

[0007] 4) Traditional methods cannot filter out invalid data and easily interfere with data analysis;

[0008] 5) The traditional method stores data information as analog level information, which is extremely inconvenient for data analysis in the later stage;

[0009] 6) The traditional method can only receive data passively, and cannot simulate the master device to control the bus
