A charger control system and method

Abstract

The invention discloses a charging machine control system, which includes a DSP unit, a PowerPC unit and a host computer. The DSP unit and the PowerPC unit communicate with each other through a dual-port RAM unit; the host computer and the PowerPC unit communicate with each other through an Ethernet Network communication connection for remote real-time monitoring and maintenance of the charger. The invention also discloses a charging machine control method. The host computer sends a command signal to the PowerPC unit through the Ethernet, and the PowerPC unit receives the command signal from the host computer and sends it to the DSP unit through a dual-port RAM unit. DSP performs corresponding actions according to the command signal of the host computer. Both the control system and the control method of the present invention have the advantages of remote monitoring, convenient maintenance, stable operation and the like.

Description

technical field [0001] The invention mainly relates to the technical field of chargers, in particular to a charger control system and method. Background technique [0002] At present, the battery charger needs high-precision output control, but the connected battery load may change greatly, and often requires the hardware to set the potentiometer to adjust to meet the requirements, and the adjustment of the potentiometer can only be a linear change, for nonlinear changes The adjustment is difficult to meet; when the charger is maintained and debugged, it needs to be debugged and maintained through the RS232 interface and the program is downloaded through the JTAG port. At the bottom, when running online, you can only observe the basic status information through the display, and you cannot see the real-time waveform. To detect the real-time waveform, you need to connect an oscilloscope and other testing equipment, which increases the difficulty of detection and will also affe...

[0002] At present, the battery charger needs high-precision output control, but the connected battery load may change greatly, and often requires the hardware to set the potentiometer to adjust to meet the requirements, and the adjustment of the potentiometer can only be a linear change, for nonlinear changes The adjustment is difficult to meet; when the charger is maintained and debugged, it needs to be debugged and maintained through the RS232 interface and the program is downloaded through the JTAG port. At the bottom, when running online, you can only observe the basic status information through the display, and you cannot see the real-time waveform. To detect the real-time waveform, you need to connect an oscilloscope and other testing equipment, which increases the difficulty of detection and will also affect driving; when the charger is running online When a fault occurs, it is often not possible to check it immediately. The vehicle needs to be repaired after returning to the warehouse. The situation on the site is becoming more and more complicated. In order to analyze the cause of the fault as soon as possible, it is necessary for the charger itself to record more and more relevant information. And the collection frequency is also required to be higher and higher
