The invention discloses a multifunctional voltage and current collecting system for a single-chip microcomputer. The multifunctional voltage and current collecting system is formed by connecting a conditioning circuit module and an isolating circuit module. Voltage and current needing to be collected are input into the conditioning circuit module for voltage conversion. The output end of the conditioning circuit module is connected with the input end of the isolating circuit module, and the output end of the isolating circuit module is connected with an A / D module of the single-chip microcomputer. The multifunctional voltage and current collecting system can collect 3 V-500 V voltage and current of any magnitude and collect voltage and current supplied by single power sources or double power sources. The multifunctional voltage and current collecting system is made of common electronic devices, and is simple in structure, low in manufacturing cost and wide in application range. The single-chip microcomputer can be protected as optical isolating is adopted.
Description
technical field [0001] The invention relates to voltage and current acquisition, and more specifically relates to a multifunctional voltage and current acquisition system for a single-chip microcomputer, which is applied to various circuits that need to acquire voltage and current. Background technique [0002] In many circuit systems, such as bidirectional DC-DC converters, smart substation battery pack detection systems, battery management systems, etc., it is necessary to collect voltage and current data and process the data through a single-chip microcomputer. However, the input voltage of the A / D module of the single-chip microcomputer cannot exceed 3V, so the voltage and current need to be processed in the acquisition system so that the maximum input voltage of the single-chip microcomputer is not greater than 3V. However, most of the related products currently on the market are DC or AC voltage sensors and current sensors. The converted voltage specifications are fixe...
