Description

Technical Field

[0001] The invention relates to the technical field of outboard motor control, and in particular to an intelligent rear-control system for a diesel outboard motor and a use method thereof. Background Art

[0002] With the development of global trade and the continuous expansion of water tourism, fisheries and other industries, the demand for reliable outboard power systems continues to increase. Especially in some scenarios that require long-distance sailing, high-load transportation and operation in harsh sea conditions, diesel outboard engines are highly favored due to their powerful power and durability.

[0003] Users have put forward higher requirements for the operation control system of diesel outboard engines, hoping to achieve more convenient and accurate control. The rear control system allows operators to operate directly at the stern, better observe the surrounding environment and ship dynamics, and improve the safety and efficiency of operation.

[0004] The continuous development of modern electronic control technology has made the control system of outboard motors more intelligent and automated. Technologies such as electronic throttle and electronic tilting can be used to improve the accuracy and response speed of operation while reducing the difficulty of operation. At the same time, with the continuous improvement of the integration of communication technology and ship electronic systems, the diesel outboard motor rear control system can be connected in parallel with other ship equipment to achieve more comprehensive monitoring and management of various performance parameters of the diesel engine.

[0005] Safety is always of vital importance in water operations. The after-control system allows operators to better understand the dynamics of the ship, respond in time, and reduce the risk of accidents. When a ship is sailing at sea, it faces a variety of complex environments and working conditions. The diesel outboard engine after-control system needs to have high reliability and stability to ensure the safe operation of the ship.

[0006] At present, the rear-operation control methods of domestic outboard motors are basically mechanical. The control systems such as engine start and stop, throttle control and gear shifting are all mechanically controlled. It is impossible to monitor and manage the performance parameters of the whole machine. The operation accuracy and response speed are slow, which greatly increases the difficulty of operation. When encountering complex sea conditions, the safety factor is low, and the mechanical control system cannot respond in time, increasing the probability of accidents.

[0007] Moreover, the start and stop, throttle control and other functions of the electronically controlled high-pressure common rail diesel outboard engine are all electronically controlled by the ECU. The existing domestic rear-control systems cannot match the rear-control of the electronically controlled high-pressure common rail diesel outboard engine. Therefore, in response to the above problems, this patent has designed an integrated intelligent rear-control system that matches the electronically controlled high-pressure common rail diesel outboard engine. The system solves the problem of matching the rear-control of the electronically controlled high-pressure common rail diesel outboard engine with the boat. The system adopts a highly integrated design, an intelligent human-machine interface, and combines ergonomic integrated design. It is fully functional, simple to operate and more comfortable. It can monitor and manage various performance parameters of the whole machine operation, with faster operating accuracy and response speed, convenient operation, fast response speed in complex sea conditions, high safety factor, and greatly reduce the occurrence of accidents.

[0031] The rear control handle 5 is structurally divided into two parts: an upper shell cover 53 and a lower shell 58; the upper shell cover 53 is hinged to the rear end connecting seat 3 to achieve the height adjustment of the operating rod of the rear control handle 5, and at the same time, a throttle control mechanism 59 is integrated at the end of the upper shell cover 53 to control the throttle; the rear control relay control unit 7 and wiring harness are integrated inside the lower shell 58 to achieve the control of functions such as tilting, diesel outboard engine starting, ECU and gear shifting, and at the same time realize functions such as fault alarm.
