Driver batch upgrading method and device

The invention discloses a driver batch upgrading method and device, and relates to the driver batch upgrading technology, the method comprises the steps that upgrading firmware content is divided into a plurality of data segments with specified lengths, the divided upgrading firmware is transmitted to each to-be-upgraded driver, the transmission process of each data segment comprises three kinds of messages, and the messages are sent to the to-be-upgraded driver. The three messages are a start message, a data message and an end message, the start message comprises segment number information and byte total number information, the data message comprises all upgrade firmware contents of corresponding segments, the end message comprises segment number information and CRC check codes, each segment of message is sent to each driver to be upgraded in a broadcast mode, and the segment number information is sent to each driver to be upgraded. All the to-be-upgraded drivers can receive the data; and after the transmiss
