Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and examples.

[0027] Such as figure 1 , 2 As shown, the control system of the present invention includes an MCU circuit 1, which is used to complete the programmed and intelligent command work in the work of the entire control system.

[0028] The MCU circuit 1 is connected with an ambient temperature acquisition circuit 3 for collecting the ambient air temperature T1 of the diesel engine. The MCU circuit 1 is also connected with a fuel tank temperature acquisition circuit 2 for collecting the temperature T2 in the fuel tank of the diesel engine.

[0029] The MCU circuit 1 is also connected with a temperature display circuit 5 for displaying T1 and T2.

[0030] The MCU circuit 1 is also connected as image 3 , 4 The control circuit shown is used to drive the output, sample the current and amplify it, and provide a stable signal for the overcurrent protection contr...

Abstract

The invention provides a heating control method and a heating control system of a diesel engine. According to the heating control method and the heating control system of the diesel engine, an MCU (Microprogrammed Control Unit) circuit (1) is respectively connected with an environmental-temperature acquiring circuit (3) for acquiring the environmental air temperature T1 of a diesel engine, an oil tank temperature acquiring circuit (2) for acquiring the oil tank temperature T2 of the diesel engine, a heating indicator circuit (4) for indicating the working state of a control system circuit, a temperature display circuit (5) for displaying T1 and T2 which are served as the basis for setting the heating temperature and the heating time, a control drive and an alarming circuit (6) for implementing a command generated via the MCU circuit (1) and performing the work of alarming, and a control circuit for driving output, amplifying sampling current and performing break protection. The heating control method and the heating control system of the diesel engine provided by the invention are high in degree of automation and intelligence, and high in safety.

Description

[0001] technical field [0002] The invention relates to a heating control method, in particular to a diesel engine heating control method. The invention also relates to a control system implementing the control method. Background technique [0003] When a diesel engine is used in winter, it usually needs to heat the fuel in the fuel tank, the oil pipe, the oil-water separator and the fine filter of the engine to ensure that the fuel can flow smoothly and burn to do work. The existing control system for this heating device is generally a manual control system. When the ambient temperature is low, the heating power supply and heating switch are manually turned on, and the heating system is manually turned off after heating for a certain period of time (the length of the time is generally set by experience). The main disadvantage of this method is that the control accuracy is relatively poor, and if the heating system is not shut down in time, it will also cause the fuel t...
