Description
Technical Field
[0001] This utility model relates to the technical field of diesel engine electronic control systems, and in particular to an expandable marine diesel engine electronic control system. Background Technology
[0002] With the increasing variety of diesel engine models, designing different electronic control systems for different diesel engines is time-consuming and labor-intensive. In response to this situation, there is an urgent need for a new type of scalable electronic control system that can meet different needs through flexible configuration for different types of diesel engines, greatly reducing the design and development cycle.
[0003] Currently, the number of diesel engines is not as large as that of vehicle engines, and different diesel engines have different structural forms. However, regardless of the changes in the structure of diesel engines, the electrical components on diesel engines can be divided into two main categories: control and data acquisition. These two categories are designed as independent modules. At the same time, considering the special characteristics of marine engines, redundant systems need to be configured in the case of a single engine, so the redundant devices also need to be designed separately.

[0025] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0026] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the technical solutions of this utility model are further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it.
[0027] See Figure 1 This utility model provides an expandable marine diesel engine electronic control system, including a monitoring module, a data acquisition module, a diesel engine controller, and a redundancy switching module;
[0028] The data acquisition module is connected to a sensor for diesel engine oil and is used to collect signals from the diesel engine.
[0029] The monitoring module is connected to an external power supply, a data acquisition module, a diesel engine controller, and a redundancy switching module, and is used to monitor signals and is responsible for signal input and output.
[0030] The diesel engine controller is connected to the diesel engine actuator and the redundancy switching module respectively, and is used to send execution signals to the diesel engine actuator.
[0031] The redundancy switching module includes a redundancy switching unit and a diesel engine redundancy controller. The diesel engine redundancy controller is connected to the diesel engine actuator and the redundancy switching unit, and is used to send execution signals to the diesel engine actuator. The redundancy switching unit is connected to the monitoring module, the diesel engine controller and the diesel engine redundancy controller respectively, and is used to switch between the diesel engine controller and the diesel engine redundancy controller according to the monitoring signal.
[0032] In this embodiment, see Figure 3 The data acquisition module has electrical interfaces that are mainly connected to the sensors and monitoring modules of the marine diesel engine. It has at least 24 PT100 / PT1000 acquisition channels, 16 K-couple acquisition channels, 16 switch input channels, 16 4-20mA acquisition channels, and 4 high-frequency pulse signal acquisition channels. At the same time, for sensors that cannot be integrated with wire harnesses, a certain number of stuffing box interfaces are provided to input individual sensors to the data acquisition module through the stuffing box interfaces.
[0033] See Figure 2 The monitoring module has electrical interfaces for connecting to an external power supply, a data acquisition module, a diesel engine controller, and a redundancy switching module. It also has a number of stuffing box type interfaces for inputting and outputting other signals from outside the system. By connecting to the data acquisition module, it can quickly acquire various data from the diesel engine sensors. By connecting to the diesel engine controller, it can control the diesel engine's fuel injection, rail pressure, etc. The monitoring module is generally located next to the diesel engine and also has indicator lights, operation buttons, and a human-machine interface.
[0034] See Figure 4 The diesel engine controller has 12 solenoid valve drive interfaces, 4 high-frequency pulse signal interfaces, 4 4-20mA current input interfaces, and 4 MEU valve drive interfaces. The diesel engine controller has connector electrical interfaces with the monitoring module and connector electrical interfaces with the redundancy switching module. The actuators on the diesel engine are arranged in the form of integrated wiring harnesses, and the connector electrical interfaces are arranged on the diesel engine controller.
[0035] See Figure 1 and Figure 4 The redundancy switching module includes a redundancy switching unit and a diesel engine redundancy controller. The redundancy switching module mainly realizes the redundancy control of the diesel engine. When redundancy control is required, the diesel engine redundancy controller is used to issue execution information to the diesel engine actuators. In application, the diesel engine redundancy controller and redundancy switching unit are generally arranged on the diesel engine to reduce the length of the control lines of each actuator, reduce the influence of interference and line resistance, and make the control more accurate.
[0036] The scalable marine diesel engine electronic control system allows for rapid transformation of the diesel engine electronic control system device by configuring or not configuring a diesel engine controller module, depending on the diesel engine's function. With a diesel engine controller configured, it becomes a diesel engine control system; without a diesel engine controller configured, it becomes a simple diesel engine monitoring instrument through the data acquisition module.
[0037] In another embodiment, a data acquisition module can be added, mainly configured according to the number of sensors in the diesel engine, to increase the data acquisition capability of the electronic control system.
[0038] In another embodiment, all of the aforementioned electrical interfaces can be located at the bottom of the module for effective dust and water protection.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
