SOC chip for electric power/energy system

Abstract

The invention discloses an SOC (System on a Chip) chip for an electric power / energy system. The SOC chip comprises a collecting module, a storage module, a signal processing module, a transmission module and a bus module, wherein the bus module comprises a high-speed system bus AHB (Advanced High Performance Bus) and a low-speed peripheral bus APB (Advanced Peripheral Bus) which are mutually connected; the signal processing module, the storage module, the transmission module and the high-speed system bus AHB are mutually connected; the collecting module and the low-speed peripheral bus APB are mutually connected; the signal processing module is concretely a ZSP400 digital signal processor; the transmission module comprises a DMA (Direct Memory Access) unit; the collecting module collects analog and digital signals at the sensor side; the analog and digital signals are transmitted to the storage module through the transmission module; and the signal processing module reads the data of the storage module and processes the data. The SOC chip has the advantages that the cost is low; the power consumption is low; the size is small; the use is convenient; and the accuracy is high.

[0003] It is a necessary and critical step to effectively process the data (voltage, current, etc.) collected by devices such as smart meters from the electronic transformer side. The quality of data processing directly affects the accuracy of the entire measurement result. Most of these products convert analog signals into digital signals directly through special electric meter chips, and then calculate and process electric energy parameters. Due to the limitations of electric meter chips, the application range is bound to be very small.
