摘要： A system and method for customs inspection and release are disclosed. In one aspect, a system includes a device layer of devices for inspection and release, at least some of which generate subject detection data. The system also includes an adaptor layer of adaptors corresponding to the devices that receive detection data from its corresponding device and convert it into an event in a formatted message. The system also includes a message service layer including a bus that receives events from the adaptor layer and constructs event messages based on them. The system also includes a processing control layer that receives and processes event messages, generates instructions associated with them, and transmits the instructions to the message service layer, which constructs instruction messages based on the received instructions and transmits them to the adaptor layer. The adaptor layer converts them into device instructions that operate based on them.
