One-way data processing system

A one-way data processing system, comprising:

• a conveyor device comprising a conveyor belt and a plurality of swing arms, with the swing arms configured to unload a target object at one of a plurality of candidate exit locations;
• an image capturing device disposed at the conveyor belt, and configured to capture image data of the target object;
• a trigger device disposed at the conveyor belt, and configured to be triggered by the target object to generate a trigger signal;
• a first processing device connected to the image capturing device, and configured to identify a type of the target object according to the image data;
• and
• a second processing device connected to the trigger device and the first processing device, and configured to drive the swing arms to unload the target object at a target exit location corresponding to the exit information among the candidate exit locations at least according to the trigger signal and exit information;
• wherein the first processing device or the second processing device is further configured to obtain a weight of the target object and obtain the exit information according to a level-exit correspondence table, the type of the target object and the weight of the target object, wherein the level-exit correspondence table comprises a plurality of type-weight levels corresponding to the candidate exit locations respectively, and a data transmission direction between the first processing device and the second processing device only comprises a direction from the first processing device to the second processing device.
