Description

Method for communicating equipment model ship based on message and system thereof The present invention relates to a communication method between a model implementing equipment of a ship and controllers controlling the model. Hardware-in-the-Loop Simulation (HILS) refers to a technology used to verify complex control systems by replacing the actual product (plant) being controlled with a virtual model (plant model) and verifying it through simulation. To establish HILS, a communication connection between the controller controlling the model and the actual product is essential, and industrial communication protocols such as CAN, Modbus, and OPC are widely used for this purpose. Among these, Modbus is widely used because it is supported by various hardware and software due to its ease of implementation and speed. However, while Modbus is simple to implement, it lacks the convenience and performance to flexibly scale into large-scale systems. Furthermore, although it provides basic security, it has limitations in that it fails to meet the latest security standards. The lack of scalability in Modbus means that if the number of communication signals increases compared to the initial configuration, communication quality and maintainability deteriorate accordingly. In particular, Modbus has limitations on the size of data that can be processed in a single communication, so data exceeding a certain size cannot be sent all at once and must be sent in multiple separate transmissions. Additionally, for added signals, the hardware and software communication connection work between the input and output sections must be performed again for each signal. In final products where the types and number of all signals are fixed and unchangeable, the disadvantages of industrial communication protocols like Modbus are not a significant issue. However, there are several problems regarding HILS and real-time data usability during the product development phase. For example, the relationship between Server (Slave) and Client (Master) must be defined for each device, and the address settings of existing devices must be changed whenever new equipment is added. Furthermore, whenever a signal is added, communication address operations must be re-performed on both the Server and Client I/O devices. In addition, data types (integers, floating-point numbers, bits) must be defined in advance, and maintenance is difficult because data characteristics (decimal points, sign presence, unit) cannot be detected via communication and must be managed separately.

FIG. 3 is a flowchart illustrating an example of a communication control method according to the present invention. Figure 4 is a diagram schematically showing the structure of an MQTT message used when communicating between modules with matched input/output tags.
