[0038] The utility model provides a function indicating device of an aircraft health system, which is described below respectively.

[0039] Figure 1 The structure diagram of an embodiment of a function indicator device for an aircraft health system provided by the utility model is as follows: Figure 1 As shown, the aircraft sanitation system 110 includes a controller 1101 , and the function indication device 10 of the aircraft sanitation system 110 includes a pre-operation indication module 120 , a water shortage indication module 130 , and a dirt tank indication module 140 ;

[0040] The pre-operation indication module 120 , the water shortage indication module 130 , and the dirt tank indication module 140 are respectively connected to the controller 110 ;

[0041] The pre-operation indication module 120 is used to display the pre-operation status after receiving the pre-operation signal sent by the controller 110;

[0042] The water shortage indication module 130 is used to display water shortage after receiving the first liquid level signal sent by the controller 110;

[0043] The waste tank indicating switch 140 is used to display whether the waste tank is fully loaded after receiving the second liquid level signal sent by the controller 110 .

[0044] It should be noted that, in a specific implementation, various modules in the utility model can be combined through a PCB panel for easy operation. In addition, the controller 1101 includes but is not limited to a programmable logic controller (PLC), and each component in the aircraft health system 110 is connected to the controller 1101, and various switches in the aircraft health system 110 are connected to the input end of the controller 1101, and the program inside the controller 1101 is used to achieve precise control of the target component, that is, the aircraft health system 110 can realize the pre-work of the health system, water tank filling, flushing cycle and other working processes through the controller 1101.

[0045] It can be understood that the aircraft health system 110 involved in this embodiment is a vacuum health system that has been widely used on the market. The various components in the aircraft health system 110 mentioned in this embodiment are not included in the protection scope of the present utility model, and therefore no further elaboration is given. The present utility model aims to connect a function indication device to the controller 1101, and realize the visualization of the working conditions of various systems inside the aircraft health system 110 through the linkage between the controller 1101.

[0046] Compared with the prior art, the functional indication device of the aircraft sanitary system provided by the utility model restores the system components of the vacuum sanitary system and infers the working principles of the various systems of the vacuum sanitary system, then connects the system components of the sanitary system with the corresponding modules in the functional indication device through a controller, and uses the indicator lights of each module to visualize the working principle and working status of the sanitary system in the form of light signals, thereby judging the correctness of the system operation, making it easy to detect faults in the vacuum sanitary system of a certain type of aircraft during the repair stage.

[0047] In a possible embodiment, the function indication device 10 further includes: a power module 150;

[0048] The power module 150 is connected to the aircraft health system 110 for providing electrical energy to the aircraft health system 110 .

[0049] It should be noted that, in this embodiment, the power module 150 itself does not have an independent battery, but acts as a power adapter, and is connected to a 28V battery provided by the outside to provide power to the aircraft health system 110.

[0050] In a possible embodiment, the pre-operation state includes: whether the aircraft hygiene system 110 is powered on, whether the aircraft hygiene system 110 is being heated, and whether there is a vacuum timeout in the aircraft hygiene system 110 .

[0051] In a possible embodiment, Figure 2 As shown, the pre-working module 120 includes: a first indicator light L1, a second indicator light L2 and a third indicator light L3;

[0052] The first indicator light L1 is used to display whether the aircraft health system 110 is powered on after receiving the pre-operation signal sent by the controller 1101;

[0053] The second indicator light L2 is used to display whether the aircraft health system 110 is being heated after receiving the pre-operation signal sent by the controller 1101;

[0054] The third indicator light L3 is used to display whether there is a vacuum timeout in the aircraft hygiene system 110 after receiving the pre-operation signal sent by the controller 1101.

[0055] It should be noted that, in a specific implementation, when troubleshooting the aircraft sanitation system 110 on the ground, it is necessary to connect an external power supply (i.e., power module 150) to the aircraft sanitation system 110 to ensure that the aircraft sanitation system 110 is powered on and each subsystem in the sanitation system can operate. Therefore, before further troubleshooting the aircraft sanitation system 110, it is necessary to first indicate the power-on state of the aircraft sanitation system 110. In addition, the pre-working system of the aircraft sanitation system 110 includes a thermostat K1 and a water tank heating pipe R1 and a pipe heating pipe R2 controlled by the thermostat K1, which are used to heat the water tank and the pipe, and also includes a vacuum switch K1 and a vacuum pump P1, which are used to pump the air in the dirt tank and the pipe out of the system to maintain the air pressure in the dirt tank and the pipe stable at -35Kpa.

[0056] Exemplarily, after the power module 150 powers on the aircraft health system 110 , the controller 1101 outputs a signal to the first indicator light L1 , and the first indicator light L1 lights up.

[0057] When the vacuum switch K1 senses that the air pressure in the system is greater than -35Kpa, it is turned on and a signal is input to the controller 1101. After receiving the input signal, the controller 1101 outputs a signal to the vacuum pump P1. The vacuum pump P1 starts to work to extract air from the system to make the pressure in the dirt box and the pipeline lower than -35Kpa. When the system pressure fails to reach the given pressure for a long time, the vacuum switch K1 transmits a signal to the controller 1101, so that the controller 1101 outputs a signal to the third indicator light L3, and L3 lights up, indicating that the system has a vacuum timeout fault.

[0058] When the system thermostat K2 detects that the system temperature is low, it is turned on and a signal is input to the controller 1101, which then transmits the signal to the heating tubes R1 and R2, causing the heating tubes R1 and R2 to start heating the water tank and pipes. At the same time, the controller 1101 also transmits a signal to the second indicator light L2, which lights up, indicating that the system's heating working status is normal.

[0059] In a possible embodiment, Figure 3 As shown, in order to increase the practicality of the present invention, the aircraft health system 110 can also transmit a heating signal to the heating pipes R1 and R2 when the thermostat K2 fails. The pre-operation indication module 120 also includes: a heating switch K3 for sending a first heating signal to the controller 1101 to control the aircraft health system 110 to heat.

[0060] It is understandable that, in a specific implementation, a button may be provided on the function indicating device 10 and connected to the heating switch K3. By pressing the button, K3 can be closed.

[0061] Specifically, when K3 is closed, a heating signal is input to the controller 1101. After receiving the heating signal, the controller 1101 transmits it to the heating tubes R1, R2 and the second indicator light L2, R1 and R2 start to heat, and L2 lights up.

[0062] In a possible embodiment, Figure 4 As shown, the water shortage indication module 130 includes: a fourth indicator light L4 for displaying water shortage after receiving the first liquid level signal sent by the controller 1101.

[0063] Specifically, after the system pre-work is completed, press the hand washing button K4, the controller 1101 transmits a signal to the water pump P2 and the water valve K6, the water valve K6 opens, the water pump P2 pumps water from the clean water tank, the clean water flows out of the faucet, and flows into the gray water tank through the pipeline. When the liquid level in the clean water tank and the gray water tank is lower than the position of the liquid level switch K5, K5 is turned on, and the controller 1101 transmits the first liquid level signal to the fourth indicator light L4, L4 lights up, indicating that the system is short of water.

[0064] In a possible embodiment, Figure 5 As shown, the waste tank indication module 140 includes: a fifth indicator light L5 for indicating whether the waste tank is fully loaded after receiving the second liquid level signal sent by the controller 1101 .

[0065] Specifically, when the amount of water in the gray water tank is appropriate, the flush button K7 is pressed, and the controller 1101 transmits a signal to the flush valve K9 and the water pump P3, the K8 valve opens, and P3 works to pump water from the gray water tank to the toilet. At the same time, the controller 1101 transmits a signal to the discharge valve K10, K10 opens, and the sewage is sucked into the pipeline under pressure and discharged into the sewage tank. When the sewage level reaches the sewage tank level switch K8, K8 is turned on, and the controller 1101 transmits a signal to the fifth indicator light L5, and L5 lights up.

[0066] In a possible embodiment, in order to further enhance the practicality of the present invention and avoid overflow caused by excessive water level in the gray water tank, the function indication device 10 also includes an emptying module 160; the emptying indication module 160 is used to send a first emptying signal to the controller 1101 to control the aircraft sanitation system 10 to be emptied, and to display the emptying after receiving the feedback signal sent by the controller 1101.

[0067] In a possible embodiment, Figure 6 As shown, the emptying module includes: an emptying switch K11 for sending a first emptying signal to the controller 1101 and a sixth indicator light L6 for displaying emptying after receiving a feedback signal sent by the controller 1101.

[0068] It can be understood that, like K3 in the above embodiment, the emptying switch K11 is not a component of the aircraft sanitary system 110. Since the utility model detects the sanitary system 110 by connecting to the controller 1101 of the sanitary system 110 and inputting various signals to 1101, accordingly, an emptying module is added in the utility model, and the aircraft sanitary system 110 can be emptied through the controller 1101, mainly for emptying the gray water tank in the sanitary system.

[0069] Specifically, after closing the emptying switch K11, the controller 1101 transmits a signal to the flushing valve K9 and the water pump P3, the K9 valve opens, and P3 works to pump water from the gray water tank to the toilet. At the same time, the controller 1101 transmits a signal to the drain valve K10, K10 opens, and the sewage is sucked into the pipe under pressure and discharged into the sewage tank. At the same time, the controller 1101 also transmits a signal to the fifth indicator light L5, and L5 lights up. After pressing the reset button K12, the emptying process ends.

[0070] In a possible embodiment, in order to enable the aircraft sanitation system 110 to resume normal operation after being emptied, as Figure 7As shown, the function indicating device 10 further includes a reset module 170 ; the reset module 170 is used to send a reset signal to the controller 1101 to control the aircraft sanitation system 110 to end the emptying procedure.

[0071] It should be noted that, in a specific implementation, the reset module 170 may be a switch element that closes the switch to input a reset signal to the controller 1101 , or may be an independent signal generator that directly inputs a reset signal to the controller 1101 .

[0072] Specifically, when the aircraft health system 110 completes the emptying procedure, since the controller 1101 is a unidirectional signal generator, the emptying procedure cannot be automatically ended. At this time, the reset module 170 sends a reset signal to the controller 1101 to reset the program in 1101, so that the variables in 1101 return to the initial values, thereby controlling P3, K9, and K10 to reset and the emptying is terminated.

[0073] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
