Abstract

The present invention provides a power supply module for expanding the working power range of a diesel engine electronic control system, including a DC-DC converter U1, a linear voltage regulator U2, a single-chip microcomputer U3, an anti-current backflow diode D1 and a switch control module. The DC converter U1, the anti-current backflow diode D1, the linear voltage regulator U2 and the core power supply terminal Vcore of the single-chip microcomputer U3 are sequentially connected, and the output terminal of the DC-DC converter U1 is also connected to the interface power supply terminal Vcc of the single-chip microcomputer U3; Both the DC-DC converter U1 and the input terminals of the switch control module are connected to the battery voltage. The invention adds a switch control module on the basis of the traditional power supply technology to realize the expansion of the working power supply range, has few components, low cost, hardly increases the layout space of components, and has strong implementability and popularization.

Description

technical field [0001] The invention belongs to the technical field of diesel engine control, and in particular relates to a power supply module for expanding the working power range of an electric control system of a diesel engine. Background technique [0002] Diesel engines are widely used in industrial fields, such as construction machinery, ships, vehicles, etc. There is no shortage of diesel engines. Electronic technology has further promoted the development of diesel engine technology, and the electronic control of diesel engines has become a trend. Speed ​​control is one of the most basic requirements for diesel engine electronic control. The operating speed of a diesel engine must be limited within a certain safe range. Overspeeding can result in damage to parts or even death. The brain of the diesel engine electronic control system is a single-chip microcomputer. The first condition for the normal operation of the single-chip microcomputer is a normal working volt...
