Electrical specifications

Adaptation of power supply system: UN930 Digital Display Controller is specially designed for the DC power supply system of marine vessels, precisely adapting to the standard voltage of 24V DC with a wide voltage adaptation range of ±20%. This feature enables it to easily cope with voltage fluctuations under the ship's starting and sudden load changes. For example, when the power grid voltage drops instantly due to the startup of high-power equipment, the controller's built-in voltage regulator circuit and power management module can automatically adjust to ensure its stable operation, avoiding data loss or control failure due to unstable voltage. In addition, the power input port adopts an anti-reverse connection design, effectively preventing equipment damage caused by wiring errors and enhancing the safety of installation and use.

Communication interface and protocol: The controller is equipped with an RS232 communication interface, which follows the EIA-232 standard protocol and supports point-to-point serial communication. Although the theoretical maximum transmission rate of RS232 is 19.2kbps, and the transmission distance is generally not more than 15 metres, it has good compatibility and stability in short-distance, relatively low real-time requirements of equipment communication scenarios within the ship. For example, when connecting with sensors, small actuators and other devices in the ship's cabin, it can reliably transmit device status data and control commands. At the same time, the controller supports custom communication protocols, and users can set parameters such as data transmission format, baud rate, and checksum method according to actual needs, so as to achieve seamless connection with equipment from different manufacturers.

Physical Specifications

Compact design: UN930 adopts a highly integrated design concept and its overall dimensions are precisely optimised, with a length, width and height of only [specific dimensions] and a weight of only 1.640 kg. This compact and lightweight shape enables it to be flexibly installed in a variety of space-constrained locations inside the ship, such as narrow control cabinets, equipment operation panels, cabin corners, etc. It supports rail mounting and installation. It can be mounted on both rail and panel mounting modes. Rail mounting can be quickly and conveniently fixed on the standard DIN rail, which is convenient for the centralised layout and maintenance of the equipment; while panel mounting embeds the controller into the equipment panel by means of the special fixing clips and screws to achieve an integrated design, which enhances the overall aesthetics and convenience of operation.

Durable protection performance: the controller shell is made of high-strength engineering plastics and metal composite materials of Norwegian origin, with excellent mechanical strength and impact resistance. After rigorous mechanical vibration test and impact test, it can withstand the continuous vibration and sudden impact generated by engine operation and wave impact during ship navigation. In terms of protection level, it reaches IP54 standard, which can effectively prevent dust from entering into the internal circuit, and at the same time, it can resist water splashing from all directions, so it can adapt to the harsh working environment of humid, dusty and oily cabin of the ship. In addition, the surface of the enclosure has been specially treated with good corrosion resistance, which can withstand the erosion of corrosive gases and liquids in the cabin for a long time and extend the service life of the equipment.

Performance characteristics

High-definition digital display

Precise and clear information presentation: The UN930 is equipped with a [size] high-resolution LCD screen with TFT (thin-film transistor) technology and 16-bit colour display capability, which can present rich and detailed image and text information. With a screen resolution of [specific resolution value], it can display various equipment operating parameters, such as voltage, current, temperature, pressure, speed, etc., in a clear and accurate manner, with an accuracy of up to two decimal places. For key parameters, eye-catching colours and large fonts are used to highlight them, ensuring that operators can read them quickly even at a distance or under complex lighting conditions. At the same time, the display supports the backlight adjustment function, which can automatically or manually adjust the brightness according to the ambient light intensity. At night or in a dimly lit cabin, the brightness of the screen can be reduced to avoid blinding the eyes; in a strong light environment, the brightness can be enhanced to ensure that the information is clearly visible.

Humanised display interface design: the display interface adopts modular design concept and is divided into four main parts: parameter display area, status indication area, operation menu area and alarm prompt area. Parameter display area dynamically displays the real-time operating parameters of the equipment, supporting a variety of data display forms, such as numbers, charts, dashboards, etc., which is convenient for the operator to intuitively understand the operating status of the equipment; status indication area through different colours of the indicators and icons, intuitively show the working status of the equipment, such as normal operation, standby, failure, etc.; operation menu area adopts a hierarchical menu structure, the operation logic is concise and straightforward, and the operation can be easily accessed to all levels of the menu, to carry out the operation of the alarm prompt area through the keys. The operation menu area adopts a hierarchical menu structure with simple and clear operation logic, through key operation, it can easily enter the menus at all levels to carry out operations such as parameter setting, function configuration, data query, etc. Alarm prompting area reminds the operator of the flashing icons and sound alarms in case of abnormalities of the equipment, and at the same time, it displays the detailed alarm information, including the type of alarm, the time of occurrence, and the possible reasons, etc., which can help to locate and solve the problems quickly.

Powerful and reliable control function

Accurate and stable equipment control: UN930 has a built-in high-performance microprocessor and specialised control chip with powerful computing and control capabilities. Through preset control algorithms and logic programmes, it is able to accurately control the connected marine equipment. For example, in the control of ship lighting system, it can realise independent switching control and brightness adjustment for each lamp or a group of lamps with an accuracy of up to 1%. For the dimming function, PWM (Pulse Width Modulation) technology is used to achieve smooth, flicker-free brightness adjustment by adjusting the duty cycle of the pulse signal, which not only meets the lighting needs of different scenes, but also saves energy effectively. In terms of ventilation system control, the speed of the fan can be automatically adjusted according to the sensor data of cabin temperature, humidity, harmful gas concentration, etc., so as to match the ventilation volume with the actual demand, and maintain the cabin air quality and environmental comfort.

Flexible and diversified control modes: It supports three modes of manual control, automatic control and remote control to meet the operational needs in different scenarios. In manual control mode, the operator can operate the equipment directly through the buttons and knobs on the controller panel, which is suitable for equipment debugging, emergency handling, etc. In automatic control mode, the controller automatically completes the control of the equipment according to the preset procedures and sensor feedback data, realising the intelligent operation of the equipment. For example, in the cabin ventilation system of a ship, when the temperature sensor detects that the cabin temperature exceeds the set threshold, the controller automatically starts the fan and adjusts the fan speed to the appropriate speed; when the temperature drops to the normal range, it automatically reduces the fan speed or stops the operation. Remote control mode is connected to the ship's central control system or remote monitoring terminal through RS232 communication interface, so that the operator can carry out real-time monitoring and control of the equipment on the bridge, in the monitoring room or in other remote locations, thus realising centralised management and remote operation and maintenance of the ship's equipment.

Intelligent data processing and management

Real-time Data Acquisition and Monitoring: UN930 has powerful data acquisition capability, which can simultaneously access multiple sensor signals and support analogue input (e.g. voltage, current, temperature, pressure, etc.) and digital input (e.g. equipment status switch signal). The data acquisition frequency can be up to 100 times / sec, which can obtain real-time and accurate equipment operation data. The collected data is pre-processed by filtering, amplification, A/D conversion, etc., and then transmitted to the microprocessor inside the controller for analysis and processing. At the same time, the controller has a built-in data buffer, which can temporarily store the collected data to ensure that the data is not lost in case of communication interruption or system failure. Through real-time data monitoring, abnormalities in equipment operation, such as parameter overruns and equipment failures, can be detected in a timely manner and alarm signals can be issued immediately.

Fault diagnosis and predictive analysis: Based on the collected equipment operation data, UN930 adopts advanced fault diagnosis algorithms and models, which can quickly locate and diagnose equipment faults. When an abnormality occurs in the equipment, the controller determines the type and cause of the fault through the comprehensive analysis of multiple related parameters, combined with the preset fault rule base, and displays detailed fault diagnosis information on the display. For example, in the ship pump system, when the pump current is detected to be abnormally high, the outlet pressure drops and the running time exceeds a certain threshold, the controller can diagnose the pump may be clogged or impeller damage and other faults, and give the corresponding maintenance recommendations. In addition, the controller also has a fault prediction function, through the trend analysis of equipment historical data and real-time data, the use of machine learning algorithms to establish equipment health model, predict the future operating state of the equipment and possible failures, issued in advance warning, so that maintenance personnel can carry out preventive maintenance before the failure occurs, reducing equipment downtime and maintenance costs.

Data storage and query management: Built-in large-capacity non-volatile memory can store up to [specific time] of equipment operation data, operation records and fault information. The data storage adopts cyclic overwriting method, when the storage space is insufficient, the earliest data will be overwritten automatically to ensure the integrity of the latest data. Operators can conveniently query the historical data through the buttons on the controller panel or the communication interface. It supports filtering and searching by time, equipment type, parameter type, etc. The query results can be shown on the display in the form of tables or charts, and can also be exported to an external storage device or computer through the communication interface for further analysis and processing. These historical data not only provide an important basis for equipment maintenance and management, but also can be used to optimise equipment operating parameters, improve control strategies and enhance the overall operating efficiency of the ship.
