[0027] The specific embodiments of the present invention will be described in detail below. It should be noted that the embodiments described herein are only for illustration and are not intended to limit the present invention. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present invention. However, it is obvious to those of ordinary skill in the art that these specific details do not need to be adopted to implement the present invention. In other examples, in order to avoid confusing the present invention, known circuits, software or methods are not specifically described.

[0028] In one embodiment, see Figure 1 , Figure 1 This is a first layout diagram of a smart toilet system based on the Internet of Things in an airport environment provided by an embodiment of the present invention. Figure 1 A rectangular box in the figure represents a toilet seat, and a triangle in any rectangular box represents a toilet seat cleanliness maintenance module arranged in the toilet seat.

[0029] like Figure 1 As shown, the smart toilet system based on the Internet of Things in an airport environment provided by an embodiment of the present invention includes: at least one toilet cleanliness maintenance module, any toilet cleanliness maintenance module is used to collect the occupancy time of the corresponding toilet, and adjust the flushing parameters and the exhaust parameters according to the occupancy time.

[0030] It is known that any airport includes one or more airport terminals; any airport terminal is equipped with multiple toilets; multiple toilets are distributed in different areas of the airport terminal for passengers and staff to use; any toilet is usually divided into ordinary toilets and special toilets.

[0031] Furthermore, special toilets are usually open to mothers and babies, the disabled and other people with weak or limited behavioral abilities. Any special toilet usually only contains one toilet; ordinary toilets (including women's toilets and men's toilets) will have multiple toilets according to the size of the room and the flow of people.

[0032] In this embodiment, the data of the toilet cleanliness maintenance module in the smart toilet system based on the Internet of Things is determined according to the specific number of toilets in the airport environment, that is, one toilet corresponds to one toilet cleanliness maintenance module, so as to accurately maintain the cleanliness of each toilet in the airport environment.

[0033] For further information, see Figure 2 , Figure 2 This is a schematic diagram of the composition of the toilet cleanliness maintenance module provided by an embodiment of the present invention. Figure 2 As shown, any toilet cleanliness maintenance module in the smart toilet system provided in the embodiment of the present invention includes: a toilet occupancy detection submodule, an air quality detection submodule, a cleanliness maintenance submodule, an exhaust device control submodule and a flushing device control submodule; the cleanliness maintenance submodule is signal-connected to the toilet occupancy detection submodule, the air quality detection submodule, the exhaust device control submodule and the flushing device control submodule respectively.

[0034] In this embodiment, the toilet occupancy detection submodule is used to detect the occupancy time of the toilet and to store the historical data of the toilet occupancy time; the air quality detection submodule is used to detect the environmental data in the corresponding toilet, and the environmental data include air temperature, air humidity, ammonia concentration and hydrogen sulfide concentration; the cleanliness maintenance submodule is used to generate and adjust flushing parameters and exhaust parameters according to the current toilet occupancy time, the historical data of the toilet occupancy time, and the environmental data; the flushing device control submodule is used to generate a flushing device control signal according to the flushing parameters, and the flushing device control signal is used to control the flushing time and flushing water volume of the flushing device; the exhaust device control submodule is used to generate an exhaust device control signal according to the exhaust parameters, and the exhaust device control signal is used to control the exhaust time and exhaust power of the exhaust device.

[0035] Furthermore, the occupancy detection submodule can detect the occupancy time of the corresponding toilet seat through any one of an infrared toilet seat detection sensor, an ultrasonic toilet seat detection sensor and a pressure toilet seat detection sensor.

[0036] It is understandable that the type of core sensor selected by the occupancy detection submodule, the sensor's layout position and layout method can be selected and installed according to actual conditions.

[0037] Furthermore, the air quality detection submodule can obtain corresponding gas data through a temperature sensor, a humidity sensor, an ammonia concentration detector, and a hydrogen sulfide concentration detector.

[0038] Furthermore, in order to achieve control operations such as extending, maintaining, and shortening the flushing time, and to achieve control operations such as increasing, maintaining, and reducing the flushing water volume, the flushing device control submodule is also connected to the flushing device signal of the toilet to control the flushing time and flushing water volume of the toilet flushing device.

[0039] Similarly, in order to achieve control operations such as extending and maintaining the vacuum time, and increasing, maintaining, and reducing the vacuum power, the vacuum equipment control submodule is also connected to the toilet vacuum equipment signal to control the vacuum time and vacuum power of the toilet vacuum equipment.

[0040] For further information, see Figure 3 , Figure 3 The flow chart of flushing parameters and air extraction parameters generation provided by the embodiment of the present invention is as follows. Figure 3 As shown, the cleanliness maintenance submodule generates and adjusts flushing parameters and exhaust parameters according to the current toilet seat occupancy time, the toilet seat occupancy time history data, and the environmental data, including the following steps:

[0041] S011. Obtain the average occupancy time and average idle time of the toilet seat for the first N-1 times, and based on the average occupancy time and the average idle time, generate the Nth flushing parameter and the Nth exhaust parameter after the toilet is occupied for the Nth time.

[0042] The flushing action proposed in the present invention is a flushing action after the toilet seat is unoccupied, so as to flush away the residual dirt in the toilet bowl; at the same time, the exhaust action proposed in the present invention is also an exhaust action after the toilet seat is unoccupied, so as to extract the aerosol brought up by the flushing action.

[0043] It is understandable that no matter the flushing action has not been performed, has just started, has been performed for a while, or has been completed when the user opens the toilet door, the smart toilet system will restart the flushing and pumping actions at the end of the occupancy.

[0044] Furthermore, the average occupancy time and average idle time of the toilet seat for the previous N-1 occupancy times can be obtained through the toilet seat occupancy time historical data.

[0045] Specifically, the average occupancy time of the toilet seat for the first N-1 times it was occupied is the quotient of the total occupancy time of the toilet seat in a period of time before the starting moment when the toilet seat was occupied for the Nth time and the number of times the toilet seat was occupied. The average idle time of the toilet seat for the first N-1 times it was occupied is the quotient of the total idle time of the toilet seat in a period of time before the starting moment when the toilet seat was occupied for the Nth time and the number of times the toilet seat was idle.

[0046] Furthermore, the Nth flushing parameter indicates the flushing time and flushing water volume after the toilet is occupied for the Nth time. In this embodiment, the longer the average occupancy time of the toilet seat for the first N-1 times, the longer the flushing time after the Nth occupancy, and the greater the flushing water volume after the Nth occupancy.

[0047] Furthermore, the Nth extraction parameter indicates the extraction time and the extraction power after the toilet is occupied for the Nth time. In this embodiment, the longer the average idle time of the toilet seat for the first N-1 times, the longer the extraction time after the Nth occupation; the longer the average occupation time of the toilet seat for the first N-1 times, the greater the extraction power after the Nth occupation.

[0048] To ensure that there is enough pumping time for each flushing action, in this embodiment, the average idle time of the toilet seat when it is occupied for the first N-1 times is set as the pumping time after it is occupied for the Nth time, and the average idle time of the toilet seat when it is occupied for the first N-1 times is used to limit the flushing time after the toilet seat is occupied for the Nth time, so that the flushing time after the Nth occupancy does not exceed the pumping time after the Nth occupancy.

[0049] S012. Obtain the occupancy time between the start time and the end time of the Nth occupancy of the toilet seat, obtain the Nth comparison result of the occupancy time and the average occupancy time, and adjust the Nth flushing parameter according to the Nth comparison result.

[0050] In this embodiment, when the Nth occupancy time is greater than the average occupancy time of the previous N-1 times, the flushing time is extended and the flushing water volume is increased; when the Nth occupancy time is equal to the average occupancy time of the previous N-1 times, the flushing time is maintained and the flushing water volume is maintained; when the Nth occupancy time is less than the average occupancy time of the previous N-1 times, the flushing time is shortened and the flushing water volume is reduced.

[0051] S013. Obtain the environmental data at the end time corresponding to the Nth occupancy of the toilet seat, and obtain a second comparison result between the environmental data and the environmental data threshold, and adjust the Nth exhaust parameter based on the second comparison result combined with the adjusted Nth flushing parameter.

[0052] It is understandable that the environmental data thresholds shown represent the limit values ​​of the gas parameters in the toilet, including the air temperature threshold, the air humidity threshold, the ammonia concentration threshold, and the hydrogen sulfide concentration threshold.

[0053] In this embodiment, when there is one or more items exceeding the standard in the environmental data, but the flushing water volume in the adjusted Nth flushing parameter remains unchanged, the pumping power in the Nth exhaust parameter is increased; when there is one or more items exceeding the standard in the environmental data, and the flushing water volume in the adjusted Nth flushing parameter increases, the pumping power in the Nth exhaust parameter is increased; when there is one or more items exceeding the standard in the environmental data, but the flushing water volume in the adjusted Nth flushing parameter decreases, the pumping power in the Nth exhaust parameter is increased.

[0054] When there are no exceeding items in the environmental data and the flushing water volume in the adjusted Nth flushing parameter remains unchanged, the pumping power in the Nth exhaust parameter is maintained; when there are no exceeding items in the environmental data, but the flushing water volume in the adjusted Nth flushing parameter increases, the exhaust power in the Nth exhaust parameter is increased; when there are no exceeding items in the environmental data and the flushing water volume in the adjusted Nth flushing parameter decreases, the exhaust power in the Nth exhaust parameter is reduced.

[0055] It can be understood that the IoT-based smart toilet system in the embodiment of the present invention can utilize the historical occupancy data and real-time environmental monitoring data of each toilet seat to dynamically adjust the flushing parameters and exhaust parameters to ensure that each toilet seat can be effectively cleaned and the air purified after each use, thereby improving the user experience and the quality of the sanitary environment.

[0056] In one embodiment, see Figure 1 and Figure 4 , Figure 4 This is a second layout diagram of the smart toilet system based on the Internet of Things in an airport environment provided by an embodiment of the present invention. Figure 4 The circle in any rectangular frame represents the toilet paper management module arranged in the corresponding toilet.

[0057] like Figure 4 As shown, based on the toilet cleanliness maintenance module deployed in the previous embodiment, the smart toilet system based on the Internet of Things in an airport environment provided by this embodiment also includes: at least one toilet paper management module, any toilet paper management module is used to collect the remaining amount of toilet paper in the corresponding toilet seat, and generate a toilet paper replenishment signal according to the remaining amount of toilet paper.

[0058] Furthermore, if Figure 5 As shown, Figure 5 Schematic diagram of the composition of the toilet paper management module provided in an embodiment of the present invention. Figure 5As shown, any one of the toilet paper management modules includes: a toilet paper weight detection submodule and a toilet paper management signal submodule; the toilet paper weight detection submodule is signal-connected to the toilet paper management signal submodule, and the toilet paper management signal submodule is signal-connected to the management display terminal, and the toilet paper weight detection submodule is used to detect the remaining amount of toilet paper in the corresponding toilet seat in real time; the toilet paper management signal submodule is used to generate a toilet paper replenishment signal according to the remaining weight of the toilet paper, and the management display terminal is used to display the toilet paper replenishment signal.

[0059] In this embodiment, the toilet paper in any toilet stall is roller toilet paper; further, the toilet paper management module provided in the present invention obtains a first pressure on the roller of the roller toilet paper through a pressure sensor, and then divides the first pressure by the local acceleration of gravity to obtain the remaining amount of toilet paper.

[0060] It is understandable that the remaining amount of toilet paper proposed in this embodiment is the mass of the remaining toilet paper. In one or some other embodiments, the toilet paper management module can also obtain toilet paper related data through other types of sensors, and then characterize the remaining amount of toilet paper through other methods, such as the number of remaining toilet paper sheets, the remaining toilet paper length, etc.

[0061] In one embodiment, see Figure 1 , Figure 4 as well as Figure 6 , Figure 6 This is a third layout diagram of the smart toilet system based on the Internet of Things in an airport environment provided by an embodiment of the present invention. Figure 6 The middle ellipse represents a hand-washing station, and the solid ellipse in any ellipse represents a hand sanitizer management module.

[0062] like Figure 6 As shown, based on the toilet cleanliness maintenance module and toilet paper management module deployed in the previous embodiment, the smart toilet system based on the Internet of Things in an airport environment provided by this embodiment also includes: at least one hand sanitizer management module, any hand sanitizer management module is used to collect the remaining amount of hand sanitizer in the corresponding washbasin, and generate a hand sanitizer replenishment signal according to the remaining amount of hand sanitizer.

[0063] Furthermore, if Figure 7 As shown, Figure 7 Schematic diagram of the composition of the hand sanitizer management module provided in the embodiment of the present invention. Figure 7As shown, any of the hand sanitizer management modules includes: a hand sanitizer weight detection submodule and a toilet paper management signal submodule; the hand sanitizer weight detection submodule is signal-connected to the hand sanitizer management signal submodule, and the hand sanitizer management signal submodule is signal-connected to the management display terminal; the hand sanitizer weight detection submodule is used to detect the remaining weight of the hand sanitizer on the corresponding hand washing table in real time; the hand sanitizer management signal submodule is used to generate a hand sanitizer replenishment signal according to the remaining weight of the hand sanitizer, and the management display terminal is used to display the hand sanitizer replenishment signal.

[0064] like Figure 6 As shown, a corresponding hand sanitizer management module is provided for each hand sanitizer on a wash basin in an airport environment. In this embodiment, the hand sanitizer on each wash basin is a pump-type bottled hand sanitizer, and the pump-type bottled hand sanitizer is placed on the surface of the wash basin away from the ground; further, the hand sanitizer management module provided in the present invention obtains the second pressure of the hand sanitizer on the wash basin through a pressure sensor, and then divides the second pressure by the local gravity acceleration to obtain the remaining amount of hand sanitizer.

[0065] It is understandable that the remaining amount of hand sanitizer proposed in this embodiment is the mass of the remaining hand sanitizer. In one or some other embodiments, the hand sanitizer management module can also obtain hand sanitizer-related data through other types of sensors, and then characterize the remaining amount of hand sanitizer in other ways, such as the remaining volume of hand sanitizer, the number of remaining hand sanitizer pumps, etc.

[0066] In one embodiment, in order to improve the overall management efficiency of toilets in an airport environment, a comprehensive maintenance module is set up for the maintenance of consumables such as toilet paper and hand sanitizer in any toilet, as well as the maintenance of air humidity, to improve the management efficiency of toilets.

[0067] Combination Figure 1 , Figure 4 , Figure 6 as well as Figure 8 , Figure 8 This is a fourth layout diagram of the smart toilet system based on the Internet of Things in an airport environment provided by an embodiment of the present invention. Figure 8As shown, based on the previous embodiment including a toilet cleanliness maintenance module, a toilet paper management module and a hand sanitizer management module, the smart toilet system based on the Internet of Things in an airport environment provided by this embodiment also includes: at least one comprehensive maintenance module, the comprehensive maintenance module is signal-connected to one or more toilet cleanliness maintenance modules in the corresponding toilet, and is signal-connected to one or more toilet paper management modules in the corresponding toilet, and is signal-connected to one or more hand sanitizer management modules in the corresponding toilet; the comprehensive maintenance module is used to obtain the average humidity data in the corresponding toilet, the remaining amount of toilet paper in one or more toilets, and the remaining amount of hand sanitizer in one or more toilets, and is used to generate maintenance parameters according to the humidity data, the remaining amount of toilet paper, and the remaining amount of hand sanitizer, and is used to generate a maintenance signal according to the maintenance parameters.

[0068] For further information, see Fig. 9 , Fig. 9 The following is a schematic diagram of the composition of the comprehensive maintenance module provided by the embodiment of the present invention. Fig. 9 As shown, a comprehensive maintenance module includes: a maintenance data acquisition submodule, a maintenance coefficient evaluation submodule and a maintenance signal generation submodule.

[0069] Among them, the maintenance data acquisition submodule is signal-connected to one or more air quality detection submodules in the corresponding bathroom, and is signal-connected to one or more toilet paper weight detection submodules in the corresponding bathroom, and is also signal-connected to one or more hand sanitizer weight detection submodules in the corresponding bathroom; the maintenance coefficient evaluation submodule is signal-connected to the maintenance data acquisition submodule, and the maintenance signal generation submodule is signal-connected to the maintenance coefficient evaluation submodule and the management display terminal respectively.

[0070] In this embodiment, the maintenance data acquisition submodule is used to obtain the average humidity data in the corresponding bathroom, the remaining amount of toilet paper in one or more toilet seats, and the remaining amount of hand sanitizer in one or more toilet seats; the maintenance coefficient evaluation submodule is used to generate maintenance parameters based on the humidity data, the remaining amount of toilet paper, and the remaining amount of hand sanitizer; the maintenance signal generation submodule is used to generate a maintenance signal based on the maintenance parameters, and the management display terminal is used to display the maintenance signal.

[0071] For further information, see Fig.10 , Fig.10 The maintenance parameter generation flow chart provided in the embodiment of the present invention is shown in FIG. Fig.10 As shown, the maintenance coefficient evaluation submodule generates maintenance parameters according to the humidity data, the remaining amount of toilet paper, and the remaining amount of hand sanitizer, including the following steps:

[0072] S021. Divide the real-time average humidity data by the humidity threshold to obtain a first maintenance coefficient.

[0073] It can be understood that in order to maintain the overall dryness of the bathroom, the humidity data acquired by the maintenance data acquisition submodule includes not only the humidity data inside each toilet seat in the bathroom, but also the humidity data outside the toilet.

[0074] Further, the average humidity data described in step S021 is the average value of all humidity data of the bathroom at the current sampling time. In addition, the humidity threshold in step S021 is a humidity limit value, which can be set by the staff according to the hygiene management standard.

[0075] In this embodiment, the first maintenance factor reflects the ratio of the humidity level in the bathroom to the humidity threshold. If the humidity exceeds the set temperature threshold, the first maintenance factor will increase, indicating that corresponding maintenance measures need to be taken to adjust the humidity, such as starting the exhaust device, increasing the power of the exhaust device, or maintaining the damaged exhaust device.

[0076] S022. Filter out a target toilet paper remaining amount from the toilet paper remaining amounts, and divide the data of the target toilet paper remaining amount by the number of toilet seats in the bathroom to obtain a second maintenance coefficient.

[0077] It is understandable that when the ratio of the remaining amount of toilet paper to the full amount of toilet paper is less than 1, the toilet paper in the corresponding toilet seat can be replaced or added. In actual situations, in order to save management costs and maintenance costs, the toilet paper in the corresponding toilet seat is supplemented or replaced only when the remaining amount of toilet paper is less than the remaining amount threshold of toilet paper.

[0078] Generally, when the remaining amount of toilet paper is 10% to 20% of the full amount of toilet paper, the toilet paper in the corresponding toilet seat is replenished or replaced. In this embodiment, the threshold of the remaining amount of toilet paper is set to 10% of the full amount of toilet paper; further, when the ratio between the remaining amount of toilet paper in a toilet seat and the full amount of toilet paper is less than 0.1, the remaining amount of toilet paper in the toilet seat is set as the target remaining amount of toilet paper.

[0079] In this embodiment, the second maintenance coefficient indicates the relative sufficiency of the remaining amount of toilet paper in the bathroom as a whole. If the remaining amount of toilet paper is low, the second maintenance coefficient will increase accordingly, indicating that toilet paper needs to be replenished.

[0080] S023. Filter out a target remaining amount of hand sanitizer from the remaining amounts of hand sanitizer, and divide the data of the target remaining amount of hand sanitizer by the number of toilet seats in the bathroom to obtain a third maintenance coefficient.

[0081] Similarly, when the remaining amount of hand sanitizer is 10% to 20% of the full amount of hand sanitizer, the hand sanitizer in the corresponding toilet is replenished or replaced. In this embodiment, the threshold of the remaining amount of hand sanitizer is set to 10% of the full amount of hand sanitizer; further, when the ratio between the remaining amount of hand sanitizer in a toilet and the full amount of hand sanitizer is less than 0.1, the remaining amount of hand sanitizer in the toilet is set to the target remaining amount of hand sanitizer.

[0082] In this embodiment, the third maintenance coefficient indicates the relative sufficiency of the remaining amount of hand sanitizer in the bathroom as a whole. If the remaining amount of hand sanitizer is low, the third maintenance coefficient will increase accordingly, indicating that the hand sanitizer needs to be replenished.

[0083] S024: Superimpose the first maintenance coefficient, the second maintenance coefficient, and the third maintenance coefficient, and generate corresponding maintenance parameters according to the superposition result and the size of the single maintenance coefficient.

[0084] It is understandable that the superposition value of the first maintenance coefficient, the second maintenance coefficient and the third maintenance coefficient can reflect the overall maintenance demand of the bathroom. Specifically, the larger the superposition value, the higher the maintenance demand of the bathroom.

[0085] Furthermore, the generation of corresponding maintenance parameters according to the superposition result and the size of the single maintenance coefficient includes the following generation strategies:

[0086] When the superposition result exceeds the superposition threshold, the maintenance parameter is all maintenance numbers in the bathroom.

[0087] When the superposition result does not exceed the superposition threshold, the first maintenance coefficient exceeds the first maintenance coefficient threshold, the second maintenance coefficient does not exceed the second maintenance coefficient threshold, and the third maintenance coefficient does not exceed the third maintenance coefficient threshold, the maintenance parameter is the partial humidity maintenance label in the bathroom.

[0088] When the superposition result does not exceed the superposition threshold, the first maintenance coefficient does not exceed the first maintenance coefficient threshold, the second maintenance coefficient exceeds the second maintenance coefficient threshold, and the third maintenance coefficient does not exceed the third maintenance coefficient threshold, the maintenance parameter is the maintenance label of some toilet paper in the bathroom.

[0089] When the superposition result does not exceed the superposition threshold, the first maintenance coefficient does not exceed the first maintenance coefficient threshold, the second maintenance coefficient does not exceed the second maintenance coefficient threshold, and the third maintenance coefficient exceeds the third maintenance coefficient threshold, the maintenance parameter is the maintenance label of some hand soap in the bathroom.

[0090] When the superposition result does not exceed the superposition threshold, the first maintenance coefficient exceeds the first maintenance coefficient threshold, the second maintenance coefficient exceeds the second maintenance coefficient threshold, and the third maintenance coefficient does not exceed the third maintenance coefficient threshold, the maintenance parameters are the partial humidity maintenance number and the partial toilet paper maintenance number in the bathroom.

[0091] When the superposition result does not exceed the superposition threshold, the first maintenance coefficient exceeds the first maintenance coefficient threshold, the second maintenance coefficient does not exceed the second maintenance coefficient threshold, and the third maintenance coefficient exceeds the third maintenance coefficient threshold, the maintenance parameters are the partial humidity maintenance number and the hand sanitizer maintenance number in the bathroom.

[0092] When the superposition result does not exceed the superposition threshold, the first maintenance coefficient does not exceed the first maintenance coefficient threshold, the second maintenance coefficient exceeds the second maintenance coefficient threshold, and the third maintenance coefficient exceeds the third maintenance coefficient threshold, the maintenance parameters are the maintenance number of some toilet paper and the maintenance number of hand sanitizer in the bathroom.

[0093] When the superposition result does not exceed the superposition threshold, the first maintenance coefficient exceeds the first maintenance coefficient threshold, the second maintenance coefficient exceeds the second maintenance coefficient threshold, and the third maintenance coefficient exceeds the third maintenance coefficient threshold, the maintenance parameters are the partial humidity maintenance number, the partial toilet paper maintenance number, and the hand sanitizer maintenance number in the bathroom.

[0094] When the superposition result does not exceed the superposition threshold, and there is no single maintenance coefficient exceeding the maintenance coefficient threshold, the maintenance parameter is a null value.

[0095] It is understandable that the superposition threshold and the maintenance coefficient threshold of each single maintenance coefficient can be set by the staff according to the hygiene management standard; the maintenance object and the location of the object can be correspondingly determined according to the maintenance parameter output person number.

[0096] Furthermore, the total maintenance number indicates the numbers of all maintainable toilet paper, hand sanitizer, and exhaust equipment in the bathroom, and the partial maintenance number is one or more of the total maintenance numbers. For example, a bathroom includes 20 toilet seats, and the toilet paper maintenance numbers are a1 to a20; the bathroom includes 10 washbasins, and the hand sanitizer maintenance numbers are b1 to b10; each of the 20 toilet seats in the bathroom corresponds to an exhaust device, and the bathroom also includes two exhaust devices outside the toilet seats, and the humidity maintenance numbers are c1 to c22.

[0097] It can be understood that the signal transmission between modules in the smart bathroom system based on the Internet of Things in any of the above embodiments can be achieved through one or more communication technologies including NB-IoT (Narrowband Internet of Things), LoRa (Long Range Low Power Radio Frequency), and Bluetooth.

[0098] Specifically, the invention proposes an IoT-based smart toilet system based on the characteristics of the airport environment, and the signal transmission between its internal modules is realized through LoRa communication technology. Compared with other IoT communication technologies, such as NB-IoT and Bluetooth, LoRa has a longer transmission distance and better signal stability. In the airport environment with a lot of electromagnetic interference, the advantages of LoRa communication technology are more prominent, which can bring a more comfortable and convenient toilet experience to airport passengers.
