Abstract

The invention discloses an online debugging device and a debugging method for a cooling fan of a vehicle engine. The online debugging device includes an acquisition unit for collecting the state parameters of the current vehicle; a control unit for unpacking and decomposing the state parameters; a data bus control unit for unpacking and decomposing the data according to the bluetooth transmission protocol Encapsulate, and transmit the encapsulated data packet back to the control unit; the Bluetooth transmission unit, the control unit controls the working mode of the transmission unit, and when the Bluetooth transmission unit is in slave mode, the control unit transmits data to the mobile terminal through the Bluetooth transmission unit Bag. The online debugging device of the present invention unpacks and decomposes the state parameters through the control unit and encapsulates the unpacked and decomposed data by the data bus control unit, and then transmits the encapsulated data packets to the mobile terminal through the Bluetooth transmission unit, thereby ensuring data The accuracy of transmission, while realizing the wireless transmission of data.

Description

technical field [0001] The invention relates to the technical field of wireless transmission, in particular to an online debugging device and a debugging method for a cooling fan of a vehicle engine. Background technique [0002] In the debugging process of the existing vehicle engine cooling fan speed control device, the on-site technicians first need to manually control, and use the data cable to connect the control device and the computer with a wired connection, so that the computer can display the collected data, so as to provide reference for related debugging . However, due to the need to insert and connect the data lines at any time, certain difficulties have been added to the debugging work of on-site technicians (such as the equipment installation location is relatively hidden or the installation location is not easy to carry out frequent plugging and unplugging of data lines, etc.). Moreover, because the plug connection of the data line is unstable and easy to lo...
