Abstract

The invention provides a digital generator system. The digital generator system comprises a central processor and a digital ignition control part, wherein the central processor comprises a speed collection part for collecting the real-time rotating speed of an original generator of the digital generator system; the digital ignition control part is connected with the central processor and is used for igniting the original generator; the central processor further comprises a pulse control part; the pulse control part is used for sending out a first pulse signal to the digital ignition control part at corresponding ignition time according to the collected real-time rotating speed and according to the corresponding relation table of the pre-stored real-time rotating speed and the ignition time so as to start the digital ignition control part to ignite and discharge a spark plug of the original generator, and thus the ignition advance angle of the original generator is controlled. According to the digital generator system, the optimal power can be obtained in time under the conditions of different loads and different rotating speeds by the original generator of the digital generator system, and the noise, oil consumption and working condition discharge pollutant of the generator can also be restricted to the lowest level.

Description

technical field [0001] The invention relates to a digital generator system, in particular to a digital generator system with a digital ignition function which can still ensure that the digital generator works at its optimum power point when the load and speed of the digital generator change. Background technique [0002] Digital generator is a new generator product field developed in recent years, and the popularization of this product mainly focuses on small generator systems below 5 kilowatts. The alternator of the digital generator set is directly combined with the engine. Compared with the traditional generator set, the size and weight of the digital generator set are reduced by 50%, which makes it applicable to many entertainment occasions and small portable electric tools. It is a real mini power plant. The key component of the digital generator is its built-in microprocessor. With the powerful modular design, it will process and purify the raw power generated by the ...
