Description

Technical Field

[0001] The invention belongs to the technical field of radar equipment, and in particular relates to a multi-protocol data acquisition and monitoring device for radar equipment. Background Art

[0002] During the training and exercises of actual combat equipment, the equipment and its external devices will generate a large amount of communication data and video display data. After the training and exercises, it is necessary to analyze the data generated by the equipment during use, and to locate faults, analyze data, and display effects from the data to determine whether the combat effect has been achieved, whether the operation training is correct, whether the video display is compliant, and whether each status unit is working normally, so as to achieve the visualization requirements of equipment data during exercises and training. Different equipment has different data protocol collection requirements, so the collection equipment is required to be able to collect data from the corresponding ports. At the same time, the data collector has miniaturization requirements and must be easy to carry, install and use. The data collector has functions such as online monitoring collection, local storage, and wireless / wired network data transmission.

[0003] Most existing technologies use fixed interface design, using single-chip microcomputers, DSPs or FPGAs and other main control chips. First, the corresponding circuit is designed for the data communication protocol, and then the program or logic design is performed according to the actual circuit to realize the collection and processing of single protocol data, and there is no window to display the current status. However, with this fixed interface design, the acquisition equipment is only suitable for specific occasions. If the usage scenario is changed and the hardware protocol changes, the circuit needs to be redesigned. If the software protocol changes, the program of the single-chip microcomputer, DSP or FPGA needs to be rewritten and then downloaded to the main control chip through the programmer. That is, one demand corresponds to one special device. Summary of the invention
