Problems solved by technology

The frequency of this control signal is limited by the frequency of some sampling data, and simply increasing the main frequency of the MCU to meet this sampling requirement will greatly increase the performance requirements and cost of the MCU.
Moreover, some data frequency requirements may exceed the performance of existing MCUs, which cannot be realized

Abstract

The invention discloses a single-chip microcomputer data sampling processing method. A complete circulating segment comprises the steps: carrying out the data sampling processing of at least one type of target data and the data sampling processing of at least one type of non-target data, wherein the number of data sampling processing times of target data is greater than the number of data sampling processing times of non-target data, and the data sampling processing comprises the steps: data collection, data analysis and data transmission. The method can adjust the processing frequency of the data corresponding to each parameter at a certain degree in a mode of differentiated data processing, so as to meet the time requirements of different parameters, thereby achieving high-performance data sampling through a lower-performance MCU. The invention also discloses a single-chip microcomputer data sampling processing system, a single-chip microcomputer, and a photovoltaic inverter.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a single-chip microcomputer data sampling processing method, system, single-chip microcomputer and photovoltaic inverter. Background technique [0002] The general practice of single-chip microcomputer (MCU) sampling data processing is to scan and collect data one by one for each analog channel, analyze, package and send the data. However, in actual project use, the upper-level processor may have different time requirements for the sampling data sent by the MCU. The result of homogeneous processing often makes the transmission of some parameters unable to meet the time requirements, while the other part of the parameters Unnecessary high-rate transfers above system time requirements. [0003] An example situation is a photovoltaic inverter such as figure 1 As shown, the MCU is used for data sampling, and then sent to the upper-level processor, after data processing and ...
