Description

[0001] The present invention relates to a fault diagnosis of a marine engine at sea using a smart phone and a method of configuring the service network,

The present invention relates to a method for diagnosing a marine engine failure in a marine environment using a smartphone, realizing the information on a real time basis by a maintenance person on land, performing quick and accurate diagnosis and measures, By using the phone application, various operating information of the marine engine in operation at sea is transmitted to the smartphone by using the wireless communication transmission device, thereby performing the operation information and fault diagnosis of the engine, This is a method designed to provide better quality customer service by being provided to the driver and the inland maintenance person who needs it as the basis of analysis of the fault diagnosis.

        Generally, a marine engine is mounted on a boat or a yacht, and is a machine that generates power by generating a propulsive force through propeller rotation and water jet injection.

Marine engine is mainly developed by changing the intake and exhaust system, the cooling system, the fuel system, etc. to suit the marine conditions of the vehicle or industrial engine. So much of it has similarities with automotive engines.

Recently, an electronic diesel marine engine is controlled by ECU (Engine Control Unit) so that each part of the engine is sensed and its operation is controlled to exhibit optimum performance. This ECU information is used, and the driver or maintenance person can check the condition of the engine and can be used as a basis for utilizing the problem in the event of a failure.

Unlike automobiles on land or industrial machinery, marine engines are not easy to diagnose and promptly respond to faults that occur during operation because of the special nature of being operated at sea. Further, as the electronic control engine is gradually applied to the marine engine, it is very difficult to accurately determine the malfunction diagnosis contents of the engine only by an external confirmation of the engine. Even if the shipowner describes the contents of the malfunction to the maintenance engineer in the inland, it is limited knowledge of the shipowner's knowledge. Therefore, even if the boat arrives at the malfunctioning boat, If you are not prepared, you will have to go back to land or tow again.

It is an object of the present invention to provide an inexpensive diagnosis scanner function using a widely used smart phone, so that a ship owner can directly check the state of the engine in real time, To the maintenance person and to confirm the initial measures in the case of simple maintenance. Since the various operating information of the engine is stored in the server in the inland real time using the smartphone wireless communication network, The present invention is intended to make it possible to promptly and accurately determine and diagnose a trouble diagnosis by analyzing and analyzing various engine operation information and a trouble code before and after a trouble.

     According to an aspect of the present invention,

An ECU 10 (Engine Control Unit) for controlling various electronic control components of the marine engine and sensing the operation,

A Bluetooth terminal type OBD 20 (On-Board Diagnosis) 20 having a black box function which is connected to the ECU 10 to transmit and receive operation information and operation information of various engines by radio,

This information is received to display the rpm, fuel consumption rate, engine throttle opening rate, fault diagnosis, and corrective measures, displays the boat's speed and trajectory with the built-in GPS function, A smartphone 30 for sending

A dedicated application 31 that is driven by the smartphone,

This information is gathered and stored in a database so that the customer (70) or the management agent (60) manager can analyze the current operating condition of the engine or the condition at the time of occurrence of the fault, A central management center 40 server providing information

And a web page 50 for accessing the server and helping an authorized administrator to easily use desired information about the engine operation and history.

With the above-described structure, the ship owner can check the operation state of the engine in real time from the sea without expensive diagnostic scanner. When the trouble occurs, the owner can directly check the trouble code and information on the action method through the smart phone, . This information can be automatically or manually sent to servers in the inland management center on a regular or irregular basis via smartphone wireless communication and delivered to the management agent of the corresponding fault engine in real time Even if the shipowner on the sea does not have expertise in the engine, he can check the stored information and engine operation history to make a more accurate diagnosis promptly and prepare for the situation if necessary. Visit the yacht and make sure that you can take immediate action and resolve it on site.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, which illustrate exemplary embodiments of the present invention. It is not limited to the embodiment.

FIG. 1 is a schematic diagram illustrating a service for a marine engine using a smartphone according to an embodiment of the present invention. FIG. FIG. 4 is a schematic configuration example of the application of the smartphone. FIG. 5 is a flowchart showing an example of the application of the smartphone, And the like, and a schematic configuration of a web page that can check and analyze various engine sensor values at the time of occurrence of the accusation and at the time of occurrence of the accusation is also an example.

This management system receives the operating information of the ECU 10 via the OBD dongle 20 connected to the marine engine operating in the sea, using the Bluetooth function of the smartphone 30, Displays on the smartphone screen using the dedicated application 31 for the system, and transmits the driving information to the driver. As shown in the example of FIG. 2, the driving information displayed at this time is an engine speed (rpm), a fuel consumption amount (l / h), a throttle valve opening (%), Cooling water temperature (℃), boat speed (knot), operation trajectory, etc., which can be changed as needed.

The driving information is automatically or manually transmitted to the inland central management center 40 using the wireless communication network of the smart phone periodically or irregularly according to the setting of the dictionary user.

When a malfunction occurs in the engine during operation of the marine engine, the ECU 10 generates a malfunction code and displays a malfunction code and an alarm on the window of the smartphone application 31 through the OBD dongle 20. The driver can directly check the details of the fault details and the action items on the smart phone by clicking the fault code, and can transmit the fault information to the central management center server 40. [ At this time, the engine running information of the time before and after the failure time is also transmitted together and used as a basis for accurately diagnosing the engine failure. This fault diagnosis function can be executed manually at any time by the driver.

The management information of the engines stored in the server of the central management center 40 is managed by the authorized administrator and the management agent 60 and the customer 70 themselves can access the server to confirm the corresponding engine information, And a web page 50 that is easy to use for this purpose. Dealers and customers can view various sensing information, such as operating time, trajectory, engine coolant temperature, rpm, fuel consumption, boat speed, etc., through the web page 50 within the permitted range according to their respective authority level have.

In particular, when a malfunction occurs in the engine, the information is received from the server of the central management center 40, and the malfunction history of the engine is delivered to the management agent 60 in real time. The engine operation state of the engine can be confirmed, thereby making it possible to prepare for quick and accurate diagnosis and action. Thereby allowing the marine customer 70 to take appropriate action at the first visit.
