Abstract

The invention discloses a glow plug controller based on an intelligent switch tube, which includes a power supply unit, a main circuit unit, a control circuit unit and a feedback unit. The main circuit unit includes a connected smart switch tube and a glow plug. Control the turn-on or turn-off of the power supply voltage of the glow plug. The control circuit unit includes a connected logic gate circuit and an SR latch chip. The logic gate circuit is used to control the turn-on and turn-off voltage provided by the power supply sub-unit of the control circuit. It is used to control the control signal of the smart switch tube; the SR latch chip is used to latch the working state of the smart switch tube; the feedback unit is used to provide the main circuit power supply subunit, the control circuit power supply subunit, and the control circuit unit respectively. Feedback signal to monitor the working status of the glow plug in real time. The invention adopts the replacement of the intelligent switch tube, which can not only realize the basic requirements for the work of the glow plug, but also realize the state detection of the working condition of the switch tube.

Description

technical field [0001] The invention relates to the technical field of intelligent control of engine glow plugs, in particular to a glow plug controller based on an intelligent switch tube. Background technique [0002] For some high-power diesel vehicles, when the diesel engine is started, especially in the cold winter, because of the low temperature outside, it is difficult to start the cycle of the engine by relying on the process of air intake, compression, explosion, and exhaust cycle. Subsidized heating is required. This auxiliary heating device is installed in the preheating chamber on the upper part of the engine cylinder, below the fuel injection nozzle. When the diesel is sprayed and atomized, it will be heated by the glow plug. When the oil gas is compressed, it will easily explode. Thereby starting the cycle of the engine to achieve normal engine cycle work. [0003] The traditional control method of the glow plug is manual control. The control circuit is compo...
