Abstract: The Smart Temperature Sensor of BACnet is the most important device for data input in BAS based on BACnet.The FPGA implementation scheme with synchronization and asynchronism for Smart Temperature Sensor of BACnet was particularly described after its basic model analyzed.The design of the scheme was from top to bottom and it was divided five functional modules.And then the detailed steps were given on disposing request and producing response belonging to the core module.Finally,emulation test proves the scheme is practicable.

Keywords: Smart temperature sensor; FPGA; MS/TP frame; Disposing request; Producing response; Mutual operation
