Description

Technical Field

[0001] The present invention relates to the field of civil aviation passenger aircraft, and specifically to an automatic cabin washroom purification system, electronic equipment and method based on the Hongmeng system. Background Art

[0002] With the development of the times, the number of global air travel continues to rise, and airplanes have become one of the main ways for people to travel. The rapid growth of the global economy has provided strong support for air travel. With the increase in per capita income and the expansion of the middle class, more and more people have the financial ability to take a plane, especially in emerging market countries such as China. The transformation of economic structure and the acceleration of urbanization have led to a large number of people gathering in cities, which has driven a surge in demand for air travel. In addition, the increasing frequency of international trade, the prosperity of the tourism industry and international cultural exchanges have also become important driving forces for the aviation industry. In this context, in order to meet the needs of residents for comfort in long-distance travel, it is urgent to upgrade the cabin of civil aviation passenger aircraft to be intelligent, and combine the open source Hongmeng operating system to automate the cabin bathroom, including odor sensors, fragrance sprayers, infrared human body sensing sensors, exhaust system controllers and other related intelligent devices.

[0003] The current civil aviation passenger aircraft cabin bathrooms lack an automatic purification system with linked equipment. For long flights, the cabin bathroom environment cannot be purified in time, which will reduce the comfort of passengers. Traditional aircraft use manual methods to purify the cabin bathroom environment, which cannot meet people's needs for travel comfort and intelligence. Failure to realize the automation of cabin bathroom purification will not be able to meet the competitiveness of the future long-distance transportation market. Summary of the invention

[0004] The purpose of the present invention is to provide an automatic cabin bathroom purification system, electronic equipment and method based on the Hongmeng system to solve the above-mentioned deficiencies in the technology.

[0005] In order to achieve the above object, the present invention provides the following technical solution: an automatic purification system for cabin washrooms based on the Hongmeng system, characterized in that it includes:

[0006] Automatic purification equipment management and control system, central control server and terminal equipment;

[0007] Furthermore, the automatic purification equipment management and control system is deployed in a central control server, which is installed inside a civil aircraft, and the terminal device is an electronic device consisting of eight modules with different functions;

[0008] Furthermore, the data generated by the eight modules with different functions are uploaded to the automatic purification equipment control system of the central control server through WiFi communication technology and MQTT communication protocol. The automatic purification equipment control system communicates with the paired modules and sends instructions to the main control chips of different modules based on the values ​​received by the central control server.

[0009] Furthermore, the MQTT communication protocol transmits data through the uplink communication module of the terminal device and the downlink communication module of the central control server based on the message publishing and subscription of the MQTT client and server.

[0010] The electronic device, i.e., the terminal device, is composed of eight modules with different functions, including: a fragrance sprayer module, an alcohol sprayer module, an alcohol sensor module, an exhaust system controller module, an infrared human body sensing sensor module, a flushing controller module, an odor sensor module, and a pressure sensor module;

[0011] Furthermore, the eight modules with different functions are all equipped with the Hongmeng system and the Hi3861 main control chip. The Hi3861 main control module is composed of the Hi3861 main control chip and peripheral circuits, wherein the peripheral circuits include a communication module.

[0012] Furthermore, the fragrance sprayer module and the alcohol sprayer module are placed on the upper part of the bathroom, spraying fragrance and alcohol toward the middle, and diffusing them to the entire bathroom area through gravity and air flow; the alcohol sensor module, the infrared human body sensing sensor module and the odor sensor module are placed in the upper and middle area of ​​the bathroom; the exhaust system controller module is located at the top of the bathroom, which is a fixed area of ​​the aircraft cabin; instructions are issued through the automatic purification equipment management and control system, and the air with excessive alcohol concentration or odor value higher than the threshold is discharged from the bathroom through the vacuum exhaust system inside the aircraft cabin; the flush controller module is connected to the vacuum drainage system of the toilet and is controlled by the automatic purification equipment management and control system; the pressure sensor module is located directly below the door bolt to collect the opening and closing status of the bathroom.

[0013] Furthermore, the fragrance sprayer module, alcohol sprayer module, exhaust system controller module and flushing controller module need to be triggered and activated by the automatic purification equipment management and control system, and the alcohol sensor module, infrared human body sensing sensor module, odor sensor module and pressure sensor module need to upload data to the automatic purification equipment management and control system at certain intervals.

[0014] The eight different modules need to be paired and connected to the automatic purification equipment control system, including the following steps:

[0015] S1: Log in to the automatic purification equipment control system;

[0016] S2: Register the terminal device in the automatic purification equipment management and control system;

[0017] S3: Subscribe to the MQTT protocol topic, select the JSON data format and set the terminal device name;

[0018] S4: Record the terminal device ID and key automatically generated by the automatic purification equipment control system;

[0019] S5: Create service ID and notes description information;

[0020] S6: Create control attributes and data types of terminal devices of the automatic purification equipment management and control system;

[0021] S7: Create command parameters for the automatic purification equipment control system to the terminal equipment;

[0022] Furthermore, the registered terminal device is used to create management and control pages for eight different modules, and an API interface for debugging and modification is provided. The terminal device ID, key and service ID are interfaces for connecting the module to the automatic purification equipment management and control system. The corresponding ID and key are modified in the macro definition of the Hongmeng system through the physical interface reserved in the module; the service ID is the name of the automatic purification equipment management and control system, and the automatic purification equipment management and control system randomly generates a digital service ID. The modules with control attributes include a fragrance sprayer module, an alcohol sprayer module, an exhaust system controller module and a flushing controller module; the data type selects an appropriate data type according to the measurement accuracy of the sensor.

[0023] The linkage control method of sensors and actuators between the eight different modules comprises the following steps:

[0024] Step 1: Start by determining whether the terminal device is accessing the control system for the first time;

[0025] If the result is yes, you need to connect to the MQTT server through Ping to obtain the IP address, then modify the IP address and MQTT client ID and key in the Hongmeng system through the API interface callback function, then modify the WIFI account and key in the terminal device environment, and finally enter the Hongmeng system initialization of the terminal device;

[0026] If the result is negative, the terminal device will be directly initialized with the Hongmeng system.

[0027] Step 2: Variables k, n and m are set to zero, and then the system initializes the WIFI communication module and MQTT client of the terminal device to determine whether the terminal device is connected to the WIFI and MQTT server normally;

[0028] If the judgment result is yes, go directly to the third step;

[0029] If the result is no, then the variable k is incremented by 1, and it is determined whether k is less than a. If it is, the initialization of the WIFI communication module and the MQTT client is repeated. If it is no, the process ends.

[0030] Step 3: Determine whether the odor sensor is triggered. If it is, execute the next judgment statement. If it is not, trigger the delay detection time t1 and repeat the step 3.

[0031] The odor sensor is triggered, and it is determined whether the pressure sensor is triggered. If it is determined to be yes, the next judgment statement is executed. If it is determined to be no, the delay detection time t1 is triggered, and the third step is repeated;

[0032] The pressure sensor is triggered to determine whether the infrared human body sensing sensor is triggered. If it is determined to be no, the fourth step is executed. If it is determined to be yes, the delay detection time t1 is triggered and the third step is repeated;

[0033] Step 4: trigger the flush controller to flush the toilet and trigger the exhaust system controller to discharge gas out of the cabin through the pressure difference, and then determine whether the variable n is less than b;

[0034] If the judgment result is yes, then execute the fifth step;

[0035] If the judgment result is no, then re-execute the fourth step;

[0036] Step 5: Trigger the alcohol sprayer to release alcohol for disinfection, then wait for a period of time t2, then trigger the exhaust system controller to discharge the gas out of the cabin through the pressure difference, and finally determine whether the variable m is less than c;

[0037] If the judgment result is yes, then execute the sixth step;

[0038] If the result of the judgment is negative, the exhaust system controller is triggered again to discharge the gas out of the cabin through the pressure difference;

[0039] Step 6: The fragrance sprayer releases the fragrance, and the process ends.

[0040] Furthermore, the delayed detection time t1 and the waiting period t2 are set times, the variable k is the number of times the WIFI communication module and the MQTT client of the terminal device are initialized, a is the set threshold, the variable n is the DAC digital-to-analog conversion analog quantity detected by the odor sensor, b is the set threshold, the variable m is the DAC digital-to-analog conversion analog quantity detected by the alcohol sensor, and c is the set threshold.

[0041] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0042] 1. The present invention deploys a central control server in the aircraft cabin, which is equipped with an automatic purification equipment control system to realize the function of automatic purification of the internal environment of the aircraft cabin washroom. Compared with the manual purification required for the traditional aircraft cabin, it reduces the workload of the crew, realizes the intelligent upgrade of the aircraft cabin, and creates a more comfortable passenger experience;

[0043] 2. The present invention deploys eight modules in the aircraft cabin lavatory to achieve real-time monitoring of the cabin lavatory environment. Compared with the traditional aircraft cabin, it reduces the odor value and the number of bacteria, which is conducive to maintaining a clean environment in the lavatory, reducing the risk of infectious disease transmission, and improving the trust of passengers in public lavatories;

[0044] 3. The eight modules installed in the aircraft cabin washroom of the present invention are all equipped with Hongmeng system and Hi3861 main control chip. Compared with the simple control buttons configured in the traditional aircraft cabin, they achieve low power consumption and low latency, meet the intelligent needs of passengers and meet practical feasibility;

[0045] 4. The automatic purification equipment control system and eight modules deployed by the present invention only require professionals to wirelessly register each module in the control system and successfully connect it to be put into use. Compared with traditional wired control technology, it reduces operation and maintenance costs and reduces the weight of the aircraft cabin, which has practical significance;
