Problems solved by technology
[0003] The above-mentioned prior art is applicable to the measurement and control of the cable length of the winch of the helicopter hoisting equipment, but the existing equipment has the disadvantages of large volume, complicated circuit design, signal acquisition by analog circuit, and high development cost.
[0004] For the helicopter hoisting equipment training simulator, due to the limitations of its internal volume, cost and control requirements, it cannot meet the above-mentioned existing winch keyboard box design requirements and cannot be used. Therefore, it is urgent to study a digital circuit implementation using general components. winch keyboard box device

Description
technical field [0001] The invention belongs to the technical field of training equipment, and in particular relates to a winch keyboard box device used for helicopter hoisting simulation training. Background technique [0002] Nowadays, in the design of helicopter equipment hoisting devices, winch is a common device for helicopter hoisting equipment. The winch currently used uses a mechanical length measuring instrument for cable length deployment. The error caused by mechanical slipping and wear during measurement is relatively large, and the measurement accuracy Low, the mechanical length measuring instrument drives the counter by the mechanical transmission device, and the counter often stops due to poor lubrication. The mechanical length measuring instrument has a large volume and takes up a lot of space on the helicopter, which is not conducive to installing other equipment. The electronic measuring device can complete the collection of speed and cable length, and sen...
