Abstract: A remote reconfiguration system for an Internet of Things (IoT) intelligent sensing terminal includes: a controlled terminal with a field programmable gate array (FPGA); and a remote control unit connected to the controlled terminal and a control device; where the remote control unit is configured to receive control information sent by the control device, process the control information and send the processed control information to the FPGA, such that the FPGA performs remote local autonomous reconfiguration based on the preprocessed control information. The system resolves problems that a traditional IoT terminal cannot realize remote control and cannot follow functional requirements to perform local autonomous reconfiguration, and has better versatility and expandability.
