Embodiment Construction

[0019] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing

[0020] like figure 1 As shown, the mixed general-purpose test device of the present invention includes a chassis and a measurement and control circuit arranged in the chassis. figure 2 As shown, the display panel and the cabinet are connected by a rotating shaft and corner fittings. When turned up, any travel limit can be achieved, and when it is lowered, it can be seamlessly and flexibly fastened. The cabinet is composed of high-strength aluminum alloy and stainless steel tailor-welded. All side panels can be disassembled and assembled separately, and the LCD screen is installed on the display panel, such as image 3 As shown, the front panel of the box is equipped with control switches and indicator lights, and the upper panel of the box is equipped with a keyboard and a touch panel. Various working power sources and computer status are display...

Abstract

The invention relates to a hybrid general test device and belongs to the technical field of an avionic test. A case of a hybrid general test device adopts an upturning structure; a display plate is arranged at the upper portion of the case and a case body is arranged at the lower portion; and the display plate and the case body are connected through a rotation shaft and corner fittings. The case is compact in structure, beautiful in appearance and convenient to carry. A test circuit comprises a backboard, a processor module, a power module and a resource module, wherein the modules are connected correspondingly through the backboard. The front panel of case body is provided with control switches and indicator lights. The panels at the left and right two sides of the case body are respectively provided with a ventilation opening, wherein the two ventilation openings form an air channel. The hybrid general test device is high in reliability, and high in environment adaptability; bus bandwidth is in high and low cooperation, and the heat dissipation performance is good; and the hybrid general test device can meet the test simulation demands of different systems under test.

Description

technical field [0001] The invention relates to a mixed general testing device, which belongs to the technical field of avionics testing. Background technique [0002] With the development of computer bus technology and the update of measurement and control requirements, the demand for building some high-speed or high-speed and medium-speed mixed test resource platforms is increasing. At present, most of the computer products supporting design in the market are PCI-e mixed bus structure. , using the "golden finger" form, the contact surface is easy to oxidize and loosen after a long time, and the development carrier as a test platform has low reliability and poor versatility. The PXI-e bus expansion test platform with the same bandwidth as the PCI-e bus can better overcome the above shortcomings, but there are few types and suppliers, the selection space for related test systems is small, and the design work is relatively inconvenient. Convenience, the development requireme...
