[0002] With the continuous advancement of navigation technology and the rapid development of ship automation, the stability and reliability of the performance of marine control boxes as the core components of key ship systems are crucial to the safe operation of ships.

Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.

[0042] First, as Figure 1 As shown, in one embodiment, the present application provides a marine control box environment adjustment system, the marine control box environment adjustment system comprising:

[0043] Single chip microcomputer main control unit 1;

[0044] A temperature and humidity sensor unit 2, wherein the temperature and humidity sensor unit 2 is electrically connected to the single-chip computer main control unit 1;

[0045] A smoke sensor unit 3, wherein the smoke sensor unit 3 is electrically connected to the single-chip computer main control unit 1;

[0047] An external output serial port unit 5, the external output serial port unit 5 is electrically connected to the single-chip main control unit 1, and the external output serial port unit 5 is used for communication connection with a ship monitoring and alarm system;

[0048] The single-chip microcomputer pin extension unit 6 is electrically connected to the single-chip microcomputer main control unit 1, and the single-chip microcomputer pin extension unit 6 is used for communication connection with the environmental adjustment device.

[0049] In the above embodiment, data is collected through the smoke sensor unit 3 or the temperature and humidity sensor unit 2, and the collected environmental data is transmitted to the single-chip main control unit 1. Then, the single-chip pin expansion unit 6 is set to communicate with the environmental adjustment device, so that when the environmental data does not reach the preset threshold, the closed-loop local control is realized, and then the buzzer BUZZ is used to issue a local alarm to ensure that the crew can respond quickly. The external output serial port unit 5 is connected to the ship detection alarm system so that the alarm signal can be transmitted to the ship detection alarm system to achieve remote early warning. Through the local control of the alarm and environmental adjustment equipment, corresponding measures can be taken more timely when the control box is abnormal, thereby extending the service life of the ship control box, improving its reliability, and providing a strong guarantee for the safe navigation of the ship.

[0050] As an implementation of the smoke sensor unit 3 , the smoke sensor unit 3 uses a smoke sensor of model MQ-2.

[0051] It should be understood that the signal output terminal of the smoke sensor is connected to the single-chip microcomputer main control unit 1 to transmit the smoke sensing data detected by the smoke sensor to the single-chip microcomputer main control unit 1 .

[0052] As an implementation of the temperature and humidity sensor unit 2, the temperature and humidity sensor unit 2 adopts a temperature and humidity sensor of model DHT11.

[0053] It should be understood that the signal output end of the temperature and humidity sensor is connected to the single-chip microcomputer main control unit 1 to transmit the temperature and humidity sensing data detected by the temperature and humidity sensor to the single-chip microcomputer main control unit 1 .

[0054] Reference Figure 2 , as an implementation of the buzzer unit 4, the buzzer unit 4 includes a first NPN transistor Q1 and a buzzer BUZZ;

[0055] The base of the first NPN transistor Q1 is connected to the single-chip microcomputer main control unit 1 , the collector is connected to the power supply, and the transmitter is connected to the positive electrode of the buzzer BUZZ; the negative electrode of the buzzer BUZZ is grounded.

[0056] Specifically, refer to Figure 2 , the base of the first NPN transistor Q1 is connected to the P3.5 port of the single chip main control unit 1.

[0057] It should be understood that when the temperature and humidity sensing data or smoke sensing data detected by the temperature and humidity sensor and the smoke sensor reaches the set threshold, the single-chip main control unit 1 outputs a buzzer control signal to control the first NPN transistor Q1 to turn on, thereby turning on the power supply and the buzzer BUZZ, and then making the buzzer BUZZ emit an alarm sound to remind the staff to respond quickly.

[0058] Reference Figure 3 As a further implementation of the marine control box environment adjustment system, the marine control box environment adjustment system further includes a storage unit 71, the storage unit 71 includes a storage chip U1, a first resistor R1 and a second resistor R2;

[0059] The clock end of the memory chip U1 is connected to one end of the first resistor R1 and the single-chip main control unit 1, and the data end is connected to one end of the second resistor R2 and the single-chip main control unit 1;

[0060] The other end of the first resistor R1 is connected to a power source and the other end of the second resistor R2.

[0061] Specifically, refer to Figure 3 The clock end of the memory chip U1 is connected to the P1.0 port of the single-chip main control unit 1, and the data end is connected to the P1.1 port of the single-chip main control unit 1.

[0062] It should be understood that the first resistor R1 is connected to the clock end of the memory chip U1 to adjust the voltage or current of the clock signal to ensure that the memory chip U1 can receive a stable clock signal. The second resistor R2 is connected to the data end of the memory chip U1 to limit current or divide voltage, which can protect the memory chip U1 from damage caused by overpower or overcurrent, and at the same time stabilize the signal on the data line to improve the reliability of data transmission. The memory chip U1 is connected to the single-chip microcomputer main control unit 1 through the data end to realize data reading and writing operations.

[0063] In this embodiment, the storage unit 71 can be used to store the environmental data collected by the smoke sensor unit 3 and the temperature and humidity sensor unit 2 .

[0064] Reference Figure 4 As a further implementation of the marine control box environment adjustment system, the marine control box environment adjustment system further includes a crystal oscillator unit 72, wherein the crystal oscillator unit 72 includes a crystal oscillator X, a first capacitor C1, and a second capacitor C2;

[0065] One end of the crystal oscillator X is connected to the first crystal oscillator X end of the single-chip main control unit 1 and one end of the first capacitor C1; the other end of the crystal oscillator X is connected to the second crystal oscillator X end of the single-chip main control unit 1 and one end of the second capacitor C2;

[0066] The other end of the first capacitor C1 and the other end of the second capacitor C2 are grounded.

[0067] Specifically, refer to Figure 4 The first crystal oscillator X end may be the X1 port of the single-chip main control unit 1 , and the second crystal oscillator X end may be the X2 port of the single-chip main control unit 1 .

[0068] It should be understood that the crystal oscillator X, the first capacitor C1 and the second capacitor C2 together form a resonant circuit. When the current and voltage thereof reach a specific relationship, the crystal oscillator X will generate a stable resonant frequency to obtain a stable clock signal. Then, the clock signal enters the single-chip microcomputer through the first crystal oscillator X terminal and the second crystal oscillator X terminal of the single-chip microcomputer main control unit 1, and is used to drive the clock system inside the single-chip microcomputer to ensure the working synchronization and accuracy of the single-chip microcomputer main control unit 1 and the entire system.

[0069] The resonant frequency is determined by the physical properties of the crystal oscillator X (such as the size, shape and material of the quartz crystal) and the value of the capacitor.

[0070] In addition, the resonant frequency and the quality factor of the resonant circuit are adjusted by the first capacitor C1 and the second capacitor C2, thereby ensuring that the crystal oscillator X works stably at a specific frequency.

[0071] Reference Figure 5 As a further implementation of the marine control box environment adjustment system, the marine control box environment adjustment system further includes an indicator light unit 73, and the indicator light unit 73 is provided with a plurality of indicator light units 73; the indicator light unit 73 includes a light emitting diode D1 and a third resistor R3;

[0072] The anode of the light emitting diode D1 is connected to the power supply, and the cathode is connected to one end of the third resistor R3; the other end of the third resistor R3 is connected to the indicator light control end of the single chip main control unit 1.

[0073] Specifically, refer to Figure 5 , the indicator light control end is connected to multiple, each indicator light control end corresponds to an indicator light unit 73, and the indicator light control end can be the P2.0 port, P2.1 port, P2.2 port and P2.3 port of the single-chip main control unit 1.

[0074] In the above embodiment, the anode of the light emitting diode D1 is connected to the positive pole of the power supply, and the cathode is connected to the single-chip microcomputer main control unit 1 through the third resistor R3. If the single-chip microcomputer main control unit 1 sets the indicator light control terminal to a high level, the current will flow from the positive pole of the power supply through the light emitting diode D1 to the single-chip microcomputer main control unit 1, and the light emitting diode D1 will emit light. On the contrary, if the single-chip microcomputer main control unit 1 sets the indicator light control terminal to a low level, almost no current will flow through the light emitting diode D1, and the light emitting diode D1 will be extinguished. The third resistor R3 is used to achieve the function of current limiting, ensuring that the light emitting diode D1 emits light within the normal working current range. In this way, the single-chip microcomputer main control unit 1 controls the level state of the indicator light control terminal to control the on and off of the light emitting diode D1, so as to display the alarm information according to actual needs.

[0075] Reference Figure 6As a further implementation of the marine control box environment adjustment system, the marine control box environment adjustment system also includes a key unit 74, and the key unit 74 is provided with multiple keys. The key unit 74 includes a first key KEY1, one end of the first key KEY1 is grounded, and the other end is connected to the key receiving end of the single-chip main control unit 1.

[0076] Specifically, refer to Figure 6 The key receiving end can be the P2.4 port and the P2.5 port of the microcontroller main control unit 1.

[0077] It should be understood that when the first button KEY1 is not pressed, one end of the first button KEY1 is grounded, and the other end is disconnected from the button receiving end of the single-chip main control unit 1. At this time, the level state of the button receiving end of the single-chip main control unit 1 can be a high level. When the staff presses the first button KEY1, a path is formed at both ends of the first button KEY1, resulting in a direct connection between the first button KEY1 receiving end and the ground. At this time, the level state of the button receiving end will change rapidly, for example, to a low level. Then, the single-chip main control unit 1 determines whether the button is pressed by detecting the level state of the button receiving end. When it is detected that the level state of the button receiving end changes (such as from a high level to a low level), the single-chip main control unit 1 will perform a corresponding action. For example, in this embodiment, the button unit 74 can be used by the staff to manually end the alarm of the buzzer BUZZ or control the light-emitting diode D1 to turn off after receiving the warning of the buzzer BUZZ and the light-emitting diode D1.

[0078] Reference Figure 7 As a further implementation of the marine control box environment adjustment system, the marine control box environment adjustment system further includes a reset unit 75 including a second key KEY2, a fourth resistor R4, a fifth resistor R5 and a third capacitor C3;

[0079] The second key KEY2 is connected to one end of the third capacitor C3 and a power source, and the other end is connected to one end of the fourth resistor R4;

[0080] One end of the fifth resistor R5 is connected to the other end of the fourth resistor R4, the reset end of the single-chip main control unit 1 and the other end of the third capacitor C3, and the other end of the fifth resistor R5 is grounded.

[0081] Specifically, refer to Figure 7 The reset end of the single-chip main control unit 1 can be the RES port of the single-chip main control unit 1.

[0082] As a further embodiment of the marine control box environment adjustment system, the marine control box environment adjustment system further includes a power input unit 77 and a display unit 76;

[0083] The power input unit 77 is used to provide a 5V power supply voltage to the single-chip main control unit 1. Specifically, the power input unit 77 includes a 24V power supply, a 24V to 5V power supply unit and a 5V power input unit. The 24V power supply is electrically connected to the 24V to 5V power supply unit, the 24V to 5V power supply unit is electrically connected to the 5V power input unit, and the 5V power input unit is electrically connected to the single-chip main control unit 1. The display unit 76 is used to display the environmental data collected by the temperature and humidity sensor unit 2 and the smoke sensor unit 3.

[0084] According to the above technical solution, the working principle of this solution is as follows:

[0085] In view of the limited space on the ship, a miniaturized integrated design is adopted, which effectively saves the space of the control box itself and keeps the overall volume of the control box within a controllable range, thereby reducing production costs.

[0086] In addition, the environmental adjustment system of this embodiment has a high degree of adaptability to working conditions, and can flexibly select to use smoke sensors or temperature and humidity sensors for data collection according to the specific conditions of the ship's navigation to achieve accurate environmental adjustment. Through the provided single-chip microcomputer pin expansion unit 6, the environmental adjustment system can be connected to a relay, etc., and when the environmental data monitored by the smoke sensor or the temperature and humidity sensor does not reach a preset threshold, a closed-loop local control can be achieved, and a local alarm can be issued through the buzzer BUZZ to ensure that the crew can respond quickly.

[0087] In addition, the environmental data collected by the smoke sensor and the temperature and humidity sensor in this embodiment are integrated into one cable and sent to the ship monitoring and alarm system (AMS system) through one cable, avoiding the cumbersomeness of using multiple cables for multiple sensors in the traditional method. This embodiment uses one cable to transmit the environmental data collected by the sensor, which not only saves the use of cables but also reduces costs.

[0088] Finally, since the environmental regulation system of this embodiment adopts an intelligent regulation mechanism, the external environmental regulation device connected through the microcontroller pin expansion unit 6 does not need to work continuously, thereby extending the service life of the ship control box, improving its reliability, and providing a strong guarantee for the safe navigation of the ship.
