Description

Technical Field

[0001] The utility model relates to the technical field of simulators, in particular to a single-channel rear projection simulator. Background Art

[0002] A single-channel rear-projection simulator is usually a device used to simulate a specific signal or function, and has only one signal transmission channel. It is suitable for some scenarios that do not require a high number of channels and focus on simulating specific functions.

[0003] When using a single-channel rear-projection simulator, it is difficult to adapt to some scenarios that require multi-channel collaboration or rapid switching of different channel simulations. Adjustment and expansion are more difficult. At the same time, it can only process information from one channel at a time. When processing large amounts of data or multi-tasking requirements, the speed may be slow. For this reason, we proposed a single-channel rear-projection simulator. Utility Model Content
