A bmk telemetry data switch selection module with channel selection function

Abstract

Provided is a BMK telemetry data switching selection module with the channel selection function. The BMK telemetry data switching selection module with the channel selection function comprises an FPGA subunit, a power supply subunit, a channel strobing control address buffering subunit, a BMK telemetry data receiving sub-module, a BMK telemetry data forwarding sub-module, an indicating circuit sub-module and a clock circuit, wherein the power supply subunit is arranged on the upper left portion of the FPGA subunit, the channel strobing control address buffering subunit is arranged on the left side of the FPGA subunit, the BMK telemetry data receiving sub-module is arranged below the FPGA subunit, the BMK telemetry data forwarding sub-module is arranged above the FPGA subunit, the indicating circuit sub-module is arranged on the upper right portion of the FPGA subunit, and the clock circuit is arranged on the right side of the FPGA subunit. According to the BMK telemetry data switching selection module with the channel selection function, the number of BMK telemetry data acquisition cards is greatly reduced when collection is carried out on BMK telemetry data sent by more than one tested product, hardware cost is reduced, the number of bus expansion slots of a test computer system is reduced, and the BMK telemetry data switching selection module with the channel selection function is high in cost performance , and can be conveniently used in an integrated mode.

Description

technical field [0001] The invention relates to a BMK telemetry data switching and selection module with a channel selection function, which realizes program control and multiple selection of one (for example: 5 sets) of BMK telemetry data sent by more than one set (for example: 5 sets) of tested products. Choose 1) switch the distribution control function, and then output to the channel of the BMK telemetry data acquisition card in the test computer system. Thus, time-division multiplexing of one acquisition channel of the BMK telemetry data acquisition card can be realized, and serial acquisition of more than one channel of BMK telemetry data sent by multiple tested products can be realized. This structure is very conducive to improving the testing efficiency of multiple sets of products, greatly reducing the cost of testing systems or equipment, and saving resources and space. The invention belongs to the fields of computer communication, computer aided testing and automat...

AI Technical Summary

Problems solved by technology

If the method of configuring multiple telemetry data acquisition cards in the test computer system is adopted, a large amount of hardware and software resources are wasted, and at the same time limited by the expansion capability of the test computer system, the number of additional telemetry data acquisition cards is very limited and cannot satisfy a large number of (Example: ≥5 sets) BMK telemetry data acquisition requirements of the tested product

At present, there is no module that can realize multi-channel BMK telemetry data multi-choice switch distribution function
