[0028] Embodiments of the present invention will be described in detail below with reference to the attached drawings.

[0029] Figure 1 is a drawing showing the external appearance of the TRIM & LIST sensor (100).

[0030] Specifically, referring to FIG. 1, the explosion-proof trim and list sensor may include a main body (110), an installation part (120), and a terminal part (130), and the main body (110) may include a horizontal motion detection part (111) and a vertical motion detection part (112).

[0031] In addition, the horizontal motion detection unit (111) and the vertical motion detection unit (112) may utilize MEMS (Micro-Electro Mechanical Systems) technology to improve accuracy and exhibit fast responsiveness.

[0032] In addition, the main body (110) may include an analog circuit integrated with a MEMS chip, and the analog circuit may output 4 to 20 mA so as to be input to a sensor.

[0033] Additionally, a housing (not shown) may be installed in the installation part (120), and the installation means may be a bolt type. The installation part (120) may be installed in an explosion-proof area of ​​a ship while combined with the housing, or it may be installed directly without the housing.

[0034] Additionally, the terminal unit (130) can input and output to an external power source or control unit, and the power source or control unit may be a separate device provided in an explosion-proof area. Furthermore, power and control signals can be transmitted to and received through the terminal unit (130) via a connection with the sensor system (200).

[0035] Figure 2 is a schematic diagram illustrating the MEMS horizontal and vertical motion detection unit included in the sensor.

[0036] Specifically, referring to FIG. 2, there is a horizontal motion detection unit (111) and a vertical motion detection unit (112) capable of detecting horizontal and vertical movements through MEMS technology, and through this, the longitudinal inclination (TRIM) and transverse inclination (Heel or LIST) of the ship can be measured.

[0037] Both the horizontal motion detection unit (111) and the vertical motion detection unit (112) utilize MEMS technology, which can improve precision and enable a reasonable price and stable high performance.

[0038] The TRIM & LIST sensor (100) with MEMS technology can have an error range of 0.01 degrees, and can have significantly improved precision compared to the error range of conventional sensors, which is 0.05 degrees or 0.3 degrees.

[0044] Intrinsically safe circuits can be used in Zone 1 and Zone 2 hazardous areas as well as Zone 0 areas. Zone 0 areas are regions where the risk of explosions or other dangers persists, such as inside tanks, pipelines, or equipment, where explosive gases or vapors are continuously present at explosive concentrations. Intrinsically safe explosion protection can prevent ignition by reducing energy, as a certain amount of energy from heat or an electric spark is required for explosive gases to ignite and cause an explosion.

[0052] Additionally, the touch screen (214) may include a user interface that displays information received from the first sensor box (220), and may include a user interface that determines whether to use the received sensing information by selectively comparing and judging the information of the second sensor box (230) according to the information received from the first sensor box (220).

[0053] Additionally, the control panel (210) may include a sensor selection switch (215), and through the sensor selection switch (215), the first sensor box (220) and the second sensor box (230) may be selectively operated or sensing information may be received.

[0054] The sensor selection switch (215) may be included in the control panel (210) by mechanical means and may be included in the form of a touch switch displayed on the touch screen (214).

[0059] The PLC unit (216) may include logic that can improve the final result value by combining multiple sensing information, and may change an analog instrument panel into a digital display.

[0060] The PLC unit (216) can transmit data to a server, the transmitted data can be managed on a cloud server on a web platform, and the logic of the PLC unit (216) can be controlled on the web platform.

[0061] PLC logic controlled by a web platform can issue commands without time and space constraints based on collected sensor data, and can optimize control and operation by collecting, storing, and analyzing various sensor data generated in the ship's internal environment through methods such as operation manuals or operator intuition.
