The invention discloses a
Bluetooth intelligent mobile terminal-based hydrodynamic
retarder monitoring system, which comprises a hydrodynamic
retarder, a lower computer and an upper computer, wherein an
oil temperature sensor, a
water temperature sensor, a
pressure sensor and a hand-operated / foot-operated gear switch are arranged on the hydrodynamic
retarder, and are connected with the lower computer; the lower computer is connected with an automotive CAN (controller
area network)
bus; a first
Bluetooth module is arranged on the upper computer; a second
Bluetooth module is arranged on the lower computer; the upper and lower computers communicate through the first and second Bluetooth modules. The
system is used for monitoring the statuses of a vehicle and the retarder on line in real time by
monitoring data produced by a hydrodynamic retarder controller product in real time, and in addition, multiple functions of real-
time data acquisition and display, online debugging,
failure diagnosis and the like can be realized; the
monitoring system has multiple advantages of low cost, convenience, high speed, high reliability, reduction in requirements on technicians and the like, and meanwhile, the comprehensive application of a mobile terminal and
automotive electronics is guided.
