Portable multi-bus test equipment

Abstract

The invention relates to the field of aircraft test equipment, in particular to portable multi-bus test equipment, which comprises a CPU (central processing unit) module and further comprises: a reinforced tablet personal computer serving as an upper computer for achieving data input of a user; and a multi-bus interface board which is communicated with the reinforced tablet computer through a USB (Universal Serial Bus), serves as a lower computer for achieving equipment functions, and is used for achieving protocol processing of various buses, controlling the various buses connected with the multi-bus interface board, completing interaction with an upper computer and controlling protocol analysis.According to the invention, an infield can be used for bus-related tests; the test equipment is miniaturized, modularized and universalized, the cost is reduced, a good test platform is provided for an airplane, the multi-bus board can serve as an interface board for bus test, the cost performance is high, the system integration degree is high, the mode of the built-in interface board based on the USB bus is adopted, and the advantages of portability and integration degree are both considered.

Description

technical field [0001] The invention relates to the field of aircraft testing equipment, in particular to a portable multi-bus testing equipment. Background technique [0002] First of all, 1553B, 429, RS232, RS485, RS422 and other buses are widely used in a certain type of aircraft. Correspondingly, many boards based on CPCI, PXI, PCI, PC104 and other long-strip sockets have been introduced for the above-mentioned bus tests. However, this form takes up a lot of space and is heavy, and it is difficult to realize hand-held operation. [0003] Secondly, different bus test devices are independent of each other, and the single bus device is the main device, with low utilization rate and single function, and it is necessary to configure test devices for each bus, which leads to high user costs. [0004] Finally, although a small number of USB-based products have realized portable functions, they are all external to the device, and the integration level is not high. Contents of...

Problems solved by technology

[0002] First of all, 1553B, 429, RS232, RS485, RS422 and other buses are widely used in a certain type of aircraft. Correspondingly, many boards based on CPCI, PXI, PCI, PC104 and other long-strip sockets have been introduced for the above-mentioned bus tests. However, this form takes up a lot of space and is heavy, and it is difficult to realize handheld operation

[0003] Secondly, different bus test equipment is independent of each other, and the single bus equipment is the main one, with low utilization rate and single function. Test equipment needs to be configured for each bus, and the user cost is too high

[0004] Finally, although the few USB-based products have realized the portable function, they are all external to the device, and the integration level is not high.
