The invention discloses a preheating plug controller based on an intelligent switch tube. The preheating plug controller based on the intelligent switch tube comprises a power supply unit, a main circuit unit, a control circuit unit and a feedback unit, wherein the main circuit unit comprises the intelligent switch tube and a preheating plug which are connected, the intelligent switch tube is usedfor controlling the power supply voltage of the preheating plug to be switched on or off, and the control circuit unit comprises a logic gate circuit and an SR latch chip which are connected; the logic gate circuit is used for controlling the on-off voltage provided by a power supply subunit of the control circuit and outputting a control signal for controlling the intelligent switch tube; the SRlatch chip is used for latching the working state of the intelligent switch tube; and the feedback unit is used for respectively providing feedback signals to the main circuit power supply subunit, the power supply subunit of the control circuit and the control circuit unit and monitoring the working state of the preheating plug in real time. According to the preheating plug controller based on the intelligent switch tube, the intelligent switch tube is adopted for replacing, so that not only can the basic requirement on the working of the preheating plug be realized, but also the state detection on the working condition of the switch tube can be realized.
Description
technical field [0001] The invention relates to the technical field of intelligent control of machine 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 engine cycle depending 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 oil is sprayed and atomized, it will be heated through the glow plug. When the oil and gas is compressed, it is easy to explode. Thereby, the cycle of the engine is started, and the normal cycle of the engine is achieved. [0003] The traditional control method of glow plug is manual control. The control ...
