| Abstract: | The Neuron chip CY7C53120 and single chip computer AT89S52 were used to design the Neuron nodes based the host of using electricity parameters collection in the intelligent building, structured the LonWorks net system was structured, using the AD637 to realize the high precision convert of TRMS of the current and vol- tage, giving the modules of hardware and software. The test result has indicated that the system has realized the online measure of the power utilization parameters in the building, the error is controlled in the range of 1%. |
