Converter control circuit, converter and data interaction method

Abstract

The invention provides a converter control circuit, a converter and a data interaction method. The converter control circuit comprises a first processor, a first memory, a first Ethernet communication circuit, a data exchange circuit, a second processor, a second Ethernet communication circuit, and a wireless transmission switch. The first processor is electrically connected with the first memory, and is electrically connected with the second processor through the data exchange circuit. The second processor is used for executing a motor control algorithm program and sending produced data to the first processor. The first processor is used for executing a motor control logic operation program and storing the received data and data produced through execution of the motor control logic operation program in the first memory, and is further used for sending the data stored in the first memory to a converter managing principal computer through the first Ethernet communication circuit and the wireless transmission switch. The invention provides a converter control circuit which can upload the operation data of a converter completely and in time.

Description

technical field [0001] The embodiments of the present invention relate to automation technology, and in particular to a converter control circuit, a converter and a data interaction method. Background technique [0002] In the field of rail transit, traction converters are usually used on electric locomotives and other locomotives equipped with electric transmissions to provide variable-frequency and variable-voltage power to the traction motors. The traction converters control the operation of the locomotives by controlling and adjusting the traction motors. It has the characteristics of frequent acceleration and deceleration and high power level. Therefore, it is particularly important to record the operation data of the traction converter and ensure the stable and reliable operation of the traction converter. [0003] Most of the main control unit of the existing traction converter adopts a single CPU structure. During the train debugging stage, the CPU operation data can...
