Embodiment Construction

[0035] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways as defined and covered below.

[0036] like figure 2 As shown, the preferred embodiment of the present invention provides a general-purpose power loading device suitable for an aero-engine test bench, including:

[0037] The PLC controller, based on 2421BCD coding, designs the gears of the target power value into integer gears and decimal gears, which are used to output the corresponding gear signal according to the input target power value;

[0038] a control unit for outputting a corresponding control signal to the loading box according to the gear signal output by the PLC controller;

[0039] The loading box is used for loading the target power value according to the control signal output by the control unit.

[0040] It can be understood that the universal power loading device o...

Abstract

The invention discloses a universal power loading device and an aero-engine test bench using the same. The universal power loading device is mapped to the load gear according to a certain digitization rule by using 2421BCD code, and the decimal places can be effectively separated Gears, integers, tens, hundreds, and even thousands, the gear design rules are reasonable, and the expansibility and versatility are strong, which can effectively solve the problems of the power loading device of each test bench. The problem of compatibility has promoted the standardization process of aviation test benches.

Description

technical field [0001] The present invention relates to the technical field of aero-engine test benches, in particular, to a general-purpose electric loading device, and also to an aero-engine test bench using the above-mentioned general-purpose electric loading device. Background technique [0002] The electric loading device is widely used in the electric power measurement of aero-engine, which is used to absorb the output power of the generator. like figure 1 As shown, the traditional power loading device is mainly composed of a loading box, a control panel, a control unit, a measuring unit, a generator, and wires. The control panel includes operation buttons and gears, which are used by the operator to select a corresponding gear or a combination of multiple gears through the buttons, so as to realize the local control method of loading the target power value. The control unit includes a digital input / output module of the programmable controller, wherein the interface ...
