Abstract

The invention discloses a CAN bus engine monitor and a control method thereof, and relates to the technical field of engine monitoring equipment. The CAN bus engine monitor comprises a key operation module, a display module, an output module, a CAN communication module, a storage module and an MCU control module. The MCU control module is in charge of controlling the output module to transmit a control signal to an engine, counting the working time and the maintenance time of the engine and transmitting the counted information to the storage module. The control method comprises a start protection control method, a stop protection control method and a rotating speed setting method. By means of the start protection control method and the stop protection control method, it can be avoided thata motor is damaged in the illegal start and stop processes, and the motor is protected.

Description

technical field [0001] The invention relates to the technical field of engine monitoring equipment, and more specifically relates to a CAN bus engine monitoring instrument and a control method thereof. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy, including internal combustion engines (gasoline engines, etc.), external combustion engines (Stirling engines, steam engines, etc.), electric motors, etc. The working process of the engine is divided into intake strokes , compression stroke, power stroke and exhaust stroke. [0003] With the development of construction machinery and people paying more and more attention to environmental protection, the National III engine has been developed. The National III engine can increase the fuel injection pressure of the engine, improve the fuel adequacy of the fuel, and reduce the emission level of most harmful gases. [0004] With the popularization of the national thr...
