Problems solved by technology

[0002] The existing simulator equipment mainly adopts the traditional single independent design idea. Technically, it only needs to collect and transmit signals through a simple embedded controller and peripheral AD / DA components. This method is characterized by a relatively simple design. For the demand of a single simulator, it has certain feasibility, but it has the disadvantages of large size and no scalability
When multiple types of simulators are required to coordinate their work, it is necessary to pile up and use multiple simulators of different types. Each simulator is an independent embedded control system. Such an overall design has a large volume and low resource utilization. , the disadvantage of inconvenient use

Embodiment Construction

[0061] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0062] Such as figure 1 As shown, a kind of multiplexing general aviation simulator of the present invention comprises a clock module, a dual-channel baseband source module, a dual-channel up-conversion module, a dual-channel digitizer module, a dual-channel down-conversion module, a 20G up-conversion module and a 20G down-conversion module. Frequency conversion module; because the simulators used in the field of general aviation testing not only have the function of transmitting signals (such as microwave landing system, instrument landing, VOR, etc.) ). Therefore, the multiplexed general aviation simulator should have these two functions at the same time, as a transmitter (signal source), it has the function of generating and transmitting signals, and as a receiver, it has the functions of receiving and analyzing signals. In consi...

Abstract

The invention provides a multiplexing general aviation simulator, the clock module is used to provide 100MHz-6GHz and 3-20GHz local oscillator signals; the baseband signal generator is used to generate and output baseband signals; The ‑6GHz local oscillator signal modulates the baseband signal to form the transmit signal of the simulated simulator; the 20G up-conversion module modulates the baseband signal according to the 3‑20GHz local oscillator signal to generate the required simulated simulator signal Signal transmission; the dual-channel down-conversion module demodulates the externally input RF signal according to the 3-20GHz local oscillator signal to form an intermediate frequency signal; the 20G down-converter module uses the 3-20GHz local oscillator signal to demodulate the externally input RF signal Perform demodulation to generate an intermediate frequency signal; a dual-channel digitizer module is used to sample the intermediate frequency signal AD and perform signal processing to complete signal spectrum analysis and / or demodulation analysis. The invention can simulate various aircrafts, greatly reducing the volume and cost of the traditional multi-simulator system.

Description

technical field [0001] The invention belongs to the technical field of general aviation testing, in particular to a reusable general aviation simulator. Background technique [0002] The existing simulator equipment mainly adopts the traditional single independent design idea. Technically, it only needs to collect and transmit signals through a simple embedded controller and peripheral AD / DA components. This method is characterized by a relatively simple design. For the demand of a single simulator, it is feasible to a certain extent, but it has the disadvantages of large size and no scalability. When multiple types of simulators are required to coordinate their work, it is necessary to pile up and use multiple simulators of different types. Each simulator is an independent embedded control system. Such an overall design has a large volume and low resource utilization. , the disadvantage of inconvenient use. Contents of the invention [0003] In view of this, in order to...
