Parameter self-learning device for frequency converter of coal mining machine

The utility model discloses a parameter self-learning device for a frequency converter of a coal mining machine. The device comprises a power supply and a shell. The shell is provided with an operation panel. A key component and an isolating circuit component connected with the key component are arranged on the operation panel. The isolating circuit component is connected with a core processor which is connected with a display, a communication isolating circuit and a ferroelectric memory respectively. The communication isolating circuit is connected with a communication expansion chip which is connected with a frequency converter communication interface. After receiving a signal from the key component, the core processor realizes the automatic backup, learning and storage of a parameter set of the frequency converter by utilizing the connection of the communication isolating circuit, the communication expansion chip and the frequency converter communication interface. The batch uploading, downloading and storage of parameters of the frequency converter of the coal mining machine can be realized under the condition that an explosion-proof cavity cover plate of the frequency converter of the coal mining machine is not required to be opened, the safety operation of a highly-gassy, highly-dusty and high-humidity mine is ensured, and the automatic uploading, downloading and storage of the parameters of the frequency converter of the coal mining machine are involved.
