A GPRS wireless data transmission mode is provided. A server is disposed in a server cabinet. The server cabinet includes a cabinet body. A vertical panel of the cabinet body is subjected to impact molding to form a sealed cell body defined by the vertical panel and same with the cabinet body. The vertical panel of the cabinet body is provided with cut-through slots. A cover plate is hinged to theexternal wall of the vertical panel of the cabinet body and covers the cut-through slots. Integer variables are in one-to-one correspondence with GPRS communication modules. After data received are packaged by the GPRS communication modules to form data packages and the data packages are sent to the server, a data package counting and calculation program calculates the number of the data packagessent by the GPRS communication modules to the server and the number is adopted as a current value. A defect that tasks of substrate management controllers are increased and the substrate management controllers can't bear the heavy load because a large amount of messages are sent to the substrate management controllers in short time due to abnormal servers in the prior art is effectively avoided by the mode.
