[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1-5 This embodiment provides a multifunctional environmental temperature and humidity power controller, which includes a controller for automatic temperature and humidity control inside the ship and can be connected to various control devices for operation.

[0021] A multifunctional environmental temperature and humidity power controller includes a controller for receiving signals and triggering control signals to control the operation of electrical equipment; a shipboard room pressure control system connected to the controller, receiving signals from the controller to control the air pressure in the shipboard rooms; an air conditioning system connected to the controller, receiving signals from the controller to control the temperature and humidity in the shipboard rooms; a temperature module connected to the controller for user-set temperature; a humidity module connected to the controller for user-set humidity; and a human-machine interface display screen connected to the controller, which displays the graphical interfaces of the temperature and humidity modules. Users can set the temperature and humidity by clicking on the graphical interfaces of the temperature and humidity modules and simultaneously receive signals from the controller to display the shipboard temperature, humidity, and air pressure.

[0022] In this application, the human-computer interaction display screen is a waterproof and moisture-proof display screen, which includes a front cover with a display screen and an integrated back cover with a heat sink. The front cover and the back cover are locked together, and a sealing sheet is provided between the front cover and the back cover.

[0023] like Figure 3-4 As shown, the human-machine interface display screen adopts a fully sealed structure, including a housing seal, door seal, cable routing seal, and LCD screen seal. All sealing materials utilize conductive rubber strips / sheets, meeting both the requirements of a fully sealed structure and EMC testing. The display screen connects to the external system for power and signals via connectors. The connector interfaces are sealed using sealing rings and sealing rings with pressure pre-tightening, maintaining pre-tightening force during thermal expansion and contraction, ensuring long-term waterproofing and preventing water molecules from penetrating under normal pressure. Fully sealed displays typically use a metal housing, which acts as an electromagnetic shielding layer. This effectively blocks external electromagnetic waves and prevents electromagnetic interference generated by the display screen itself from affecting external devices, ensuring EMC testing. Simultaneously, the internal components' operating temperature is dissipated through the housing's heat sink.

[0024] In this application, the cabin pressure control system includes a variable frequency fan. The air conditioning system is installed in the air supply duct. The variable frequency fan is installed in the air supply duct to provide airflow. A pressure sensor is installed at the inlet end of the air supply duct and a pressure sensor is installed at the outlet end of the air supply duct. Pressure sensor one and pressure sensor two are used to transmit pressure signals to the controller. The controller controls the working state of the variable frequency fan through the fan frequency converter.

[0025] In this application, the air conditioning system includes an electric heater. A temperature sensor 1 is installed at the inlet end of the electric heater, and a temperature sensor 2 is installed at the outlet end of the electric heater. Temperature sensor 1 and temperature sensor 2 are used to transmit temperature signals to the controller, and the controller controls the on and off of the electric heater through a relay.

[0026] In this application, there are multiple electric heaters, and the multiple electric heaters can be selected from electric heaters with different heating levels, and can be used in combination to facilitate the adjustment of heating temperature.

[0027] In this application, the air conditioning system also includes a water-air heat exchange device, which and an electric heater are arranged sequentially along the airflow direction. The water-air heat exchange device is a plate heat exchanger, and its refrigerant water inlet is connected to a proportional valve. The water-air heat exchange device is installed inside the air supply duct. The function of the water-air heat exchange device is to exchange heat with the refrigerant water through the flowing air. In this process, the refrigerant water is controlled by the proportional valve to control its flow rate, thereby adjusting the efficiency and effect of heat exchange to obtain air at a lower temperature.

[0028] In this application, the controller is equipped with a start / stop button and a local / remote switch. The start / stop button and the local / remote switch are connected to the controller input interface through wires. The start / stop button controls the on / off of the electric heater, chilled water switch valve, etc., and the local / remote switch facilitates local and remote operation. When the local / remote switch is switched to local control mode, the controller receives the signal from the start / stop button and blocks the remote signal. The controller controls the on / off of the electric heater, chilled water switch valve, etc. according to the switch of the start / stop button. When the local / remote switch is switched to remote control mode, the controller receives the remote control signal, the start / stop button becomes ineffective, and the controller controls the on / off of the electric heater, chilled water switch valve, etc. according to the remote control instructions.

[0029] In this application, the controller is equipped with an analog-to-digital converter interface to facilitate the connection and signal transmission between various power detection devices and the controller. The controller is also equipped with a digital-to-analog converter interface to facilitate the transmission of control signals to the corresponding power devices.

[0030] Working principle of this utility model: During operation, the external transmitter (sensor) is connected via an electrical connector. It feeds back the detected data to an analog signal board (analog-to-digital converter / digital-to-analog converter). Ideal values ​​are set through the temperature and humidity modules to automatically regulate external electric heaters, chilled water circulation, and other equipment, achieving adjustments in temperature, humidity, pressure, and differential pressure. The temperature / humidity module is an electronic system primarily used to measure, monitor, and regulate indoor temperature and humidity to maintain a comfortable or specific working environment. As a functional module on the display screen, the temperature / humidity module detects the room's temperature and humidity in real time through sensors and transmits the data to the controller. The controller receives and processes the data, displaying the processed data on the screen for user viewing. The humidity module also features user interaction on the display screen. Users can set parameters such as temperature thresholds and alarm conditions via an app, enabling corresponding automated adjustments. If values ​​exceed the specified range, the controller will promptly detect the issue and issue an alarm, while automatically controlling related equipment to adjust parameters, such as automatically starting and stopping the electric heater, chilled water, and switching valves. The specific process involves retrieving the temperature / humidity threshold set in the memory and continuously comparing it with the actual temperature / humidity. Based on this comparison, a control signal is output to drive the corresponding equipment to perform heating, cooling, or ventilation operations, thereby maintaining the room temperature / humidity within the target range and achieving the purpose of automatic control.

[0031] In this application, the analog signal board consists of a 16-channel analog-to-digital converter, a 2-channel digital-to-analog converter, a 7-channel digital input, a 7-channel digital output, a 2-channel bus communication module, and an external connector interface circuit.

[0032] The controller receives power through an electrical connector and passes through a filter circuit and a protection circuit to the power module. The power module converts the power to 24V DC voltage to supply the display screen and the active contacts of the external transmitter, and 12V DC voltage to supply power to the analog signal board. Externally connected transmitters or sensors are connected to the analog signal board through analog input ports for analog-to-digital conversion.

[0033] The controller calculates and compares data, adjusting corresponding parameters based on set values. This includes automatically starting and stopping electric heaters and chilled water valves to achieve automatic control. Connector #7 (1) is primarily for Ethernet connectivity, connecting to external IP addresses and displays. Connectors #11 (2), #12 (3), and #13 (4) are mainly used to connect chilled water valves, electric heaters, fan inverters, and other equipment. The controller enables automation, offering powerful, practical, and highly reliable functionality.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
