Communication method of hid device based on usb interface of generator set controller

Abstract

The invention provides a communication method based on the HID device of the USB interface of the generator set controller, which is used to realize the data reading and writing of the generator set controller, including the following steps, step 1, constructing the HID device descriptor of the generator set controller, and obtaining the power generation The unit controller HID device; step 2, the generator set controller constructs a USB communication data packet according to the HID device descriptor, and the USB communication data packet carries the read and write data to be transmitted; each of the USB communication data packets includes The data packet ID number and function data packet used to distinguish different data packets; step 3, the generator set controller HID device sends a USB communication data packet to the generator set controller monitoring terminal, or receives a USB communication data packet from the generator set controller monitoring terminal. The USB communication data packet of the terminal, and analyze the data content of the USB communication data packet. The invention has the advantages of scientific design, strong practicability, standardized operation, flexibility and simplicity.

Description

technical field [0001] The invention relates to the data exchange field of generator set controllers, in particular to a communication method based on the USB interface HID device of the generator set controller. Background technique [0002] There are many parameter configurations and monitoring data of the generator set controller. Due to the limitation of geographical conditions, human conditions and equipment conditions, a computer is often needed to monitor and configure the generator set controller when configuring or monitoring on the controller panel. At the same time, the computer needs to install the corresponding Of course, there are other communication methods, but the corresponding communication module needs to be used for conversion; however, once the used communication module fails or is lost, or the drive is abnormal, the communication between the generator set controller and the computer will not be possible. [0003] USB communication has been well develope...

AI Technical Summary

Problems solved by technology

At present, the research and development company also develops USB communication, and invests a lot of manpower and material resources, but the computer still needs to install the corresponding driver, and the user cannot use it if the installation is not good, which is not conducive to the market promotion and equipment maintenance of the generator set controller.
