[0002] Drinking water equipment generally includes direct drinking water machines. A drinking water machine is a device that purifies tap water into drinking water and adds heating and cooling functions. It adds an automatic water inlet controller to the basic functions of a water dispenser. When in use, you only need to connect the piped direct drinking water machine directly to the drinking water pipe to realize automatic water inlet and direct drinking water.

[0051] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0052] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0053] The present invention provides an IoT-based method and system for monitoring drinking water equipment, which can be applied to important scenarios with high safety requirements, such as museums and children's palaces. This application updates the categories of personnel within the drinking water equipment's usage area in real time, the categories being defined according to a set contact threshold. A correspondence is established between the personnel's identifiers and categories. The identifier of the first person entering the sub-area containing the drinking water equipment is identified; the usage area includes sub-areas; the correspondence is queried based on the identifier to obtain the category of the first person; when the first person's category is detected as only the first category, the hot water outlet of the drinking water equipment is restricted, where the contact height of the first category includes personnel below a set contact threshold. When dealing with numerous personnel within the usage area or newly entering personnel, it is only necessary to confirm the identifier of the personnel entering the sub-area to determine whether there is a potential operational hazard with the drinking water equipment. When the first person's category is only the first category, the hot water outlet of the drinking water equipment is restricted, thereby providing indirect safety monitoring and protection for the corresponding personnel, solving the technical problems in the background art.

[0054] like Figure 1 The diagram shown is a main flowchart of an IoT-based water equipment monitoring method according to an embodiment of the present invention. The IoT-based water equipment monitoring method includes:

[0055] Step S10: Update the category of personnel within the area where the drinking water equipment is used in real time. The category is divided according to the personnel's set contact threshold.

[0056] Specifically, the calculated personnel height is converted into contact height, and it is determined whether the contact height reaches a set contact threshold. This is used to classify personnel within the usage area. The conversion of the calculated personnel height into contact height follows the formula below: if the personnel height is B and the contact height is A, then the subsequent steps are taken... In general, a person's head length is 1 / 7 of their height, their shoulder width is 1 / 4 of their height, and the ratio of foot length to height is approximately 1:7; therefore, the average person's single-arm reach is... That is, the contact height is Taking into account the proportional relationship of the foot pads, Therefore, the maximum value is generally taken, that is... In practice, this formula can be used as a reference and can be adjusted up or down. The contact threshold is generally set based on the height of the hot water outlet from the ground. For example, if the height of the hot water outlet from the ground is 1.2m, then the critical value B is 0.88m. That is, people above 0.88m are in the second category, otherwise they are in the first category.

[0057] Step S11: Establish the correspondence between the identifier and the category based on the personnel's identifier;

[0058] Step S12: Identify the identifier of the first person entering the sub-area where the drinking water equipment is located, wherein the area of ​​use includes the sub-area;

[0059] When identifying personnel categories, only the identifier needs to be identified. Based on the correspondence, the category corresponding to the identifier can be quickly looked up, simplifying the process of identifying categories according to contact height within the usage area. The identifier includes at least one of the following: clothing color, clothing worn, etc.

[0060] Step S13: Query the corresponding relationship based on the identifier to obtain the category of the first person;

[0061] To obtain the first person category, you only need to confirm its identifier to query; it is not necessary to identify the contact height of the first person within the area of ​​use.

[0062] Step S14: When the first person's category is detected to be only the first category, the hot water outlet of the drinking water device is restricted, where the first category includes personnel whose contact height is below a set contact threshold.

[0063] Personnel within the sub-area are considered "first-class personnel." If their category is only "first-class," it indicates a risk of contact with the hot water outlet of the drinking water equipment. In this case, water flow from the hot water outlet is restricted. For example, if the hot water outlet is opened, the solenoid valve connected to it is closed to ensure that no hot water comes out even if the outlet is opened. First-class personnel may also use tools to open the outlet; therefore, the contact height for first-class personnel is below the set contact threshold.

[0064] In this embodiment, the categories of personnel within the usage area of ​​the drinking water equipment are updated in real time. These categories are defined according to a set contact threshold. A correspondence between the personnel's identifiers and categories is established. The identifier of the first person entering the sub-area of ​​the drinking water equipment is identified. The usage area includes sub-areas. The correspondence is queried based on the identifier to obtain the category of the first person. When the first person's category is detected to be only the first category, the hot water outlet of the drinking water equipment is restricted, where the contact height of the first category includes personnel below the set contact threshold. When dealing with numerous personnel within the usage area or newly entering personnel, it is only necessary to identify the identifier of the personnel entering the sub-area to determine whether there is a potential operational hazard of the drinking water equipment, and the identification speed is fast. When the first person's category is only the first category, the hot water outlet of the drinking water equipment is restricted, thereby providing indirect safety monitoring and protection for the corresponding personnel.

[0065] like Figure 2 As shown, in a preferred embodiment of the present invention, the method further includes:

[0066] Step S20: When a second category is detected in the category of the first person, if it is determined that a first category still exists in the category of the first person, the first direction formed by the corresponding person of the second category and the drinking water equipment is identified, and the contact height of the person in the second category is not lower than a set contact threshold.

[0067] When the personnel category in the sub-region includes the second category, it is necessary to continue to detect whether the first category exists and identify the first direction. The first direction is the first direction formed by the corresponding personnel and the drinking water equipment. Specifically, it is necessary to determine whether the orientation or movement trend of the corresponding personnel includes the drinking water equipment. When it is detected that the corresponding personnel are moving towards the drinking water equipment, the first direction can be determined. The first direction is characterized as: the line connecting the center of the personnel and the drinking water equipment from the top view, and pointing from the corresponding personnel to the drinking water equipment.

[0068] Step S21: Detect whether there is a first person of the first category in the reverse extension direction of the first direction;

[0069] The reverse extension direction of the first direction is from the drinking water equipment to the corresponding person and is located relatively behind the direction in which the corresponding person is moving; when the corresponding mark of the first category is identified in the reverse extension direction, it is determined that the corresponding person of the first category exists;

[0070] Step S22: If so, determine the opening duration of the hot water outlet based on the change in distance between the first person in the second category and the drinking water equipment. The purpose of determining the opening duration based on the change in distance is to ensure that opening the hot water outlet does not pose a potential danger to the corresponding personnel in the second category.

[0071] Specifically, such as Figure 3 As shown, an example is now given of determining the opening duration of the hot water outlet based on the distance between them. The determination of the opening duration based on the change in the distance between the first person of the second category and the drinking water equipment includes:

[0072] Step S221: When the distance between the two sides reaches the first distance and gradually decreases, control the effective number of times the hot water outlet is opened mechanically to be a certain number of times or the opening time to be the first time, and issue a water collection prompt to the accompanying personnel behind.

[0073] When the distance change shows that the distance between the second category of personnel and the water dispenser reaches the first distance and gradually decreases, it indicates that the second category of personnel has the motivation to access the water dispenser and has begun to gradually approach it. At this time, the number of times the device can be opened or the duration of the opening should be strictly limited. The purpose is to prevent the first category of personnel from opening the mechanical switch after the second category of personnel leaves, which could cause danger. The effective number of times the mechanical switch can be opened is a certain number, but generally only one time is allowed. That is, the second category of personnel must complete the hot water dispensing within one time or within the first time period. The first time period has stricter requirements and is generally shorter. The distance change can be verified by image recognition of the personnel gradually approaching the several marking lines set in front of the water dispenser or by the distance sensor detecting that the feedback time is gradually shortening. At this time, it can be determined that the distance has reached the first distance and is gradually decreasing.

[0074] Step S222: While maintaining the distance between the two water appliances, detect whether there is a change in the water fixture entering the hot water outlet;

[0075] Here, "maintaining" means gradually decreasing and then keeping it basically unchanged, or with a small difference, such as a difference of a few centimeters. At this time, check whether the water fixture at the hot water outlet has changed. As mentioned above, a prompt has been issued to assist the accompanying personnel in getting hot water. The corresponding personnel may assist the accompanying personnel in getting hot water.

[0076] Step S223: If yes, then increase the effective number of times the hot water outlet is mechanically opened by one or increase the opening time by one duration. When it is detected that the water container used for this water collection is different from the previous one, and the distance between them remains unchanged, it generally means that the corresponding personnel are preparing to assist the personnel behind them in collecting hot water. At this time, the number of times the outlet is opened is increased by one or the opening time is increased, that is, the corresponding personnel are allowed to assist the personnel behind them in collecting hot water in the same number of times (generally 1) or for the same amount of time as they themselves collect water, thereby meeting the water collection needs of different types of personnel and ensuring water collection safety.

[0077] In a preferred embodiment of the present invention, the method further includes:

[0078] Step: When it is detected that only category two exists among the first personnel, the mechanical opening time of the hot water outlet is controlled to meet the second duration. The second duration is generally longer than the first duration.

[0079] The second time limit generally meets the average time for a single water dispensing session, such as 5 seconds. In practical applications, if only Category 2 individuals exist within the sub-area where the water dispenser is located, the mechanical opening time of the hot water outlet should be limited. For example, the opening time of the solenoid valve of the hot water outlet can be set to 5 seconds. Therefore, the mechanical switch must be opened simultaneously with the opening of the solenoid valve within 5 seconds for hot water to come out of the hot water outlet. If the second time limit has elapsed and it is detected that the only remaining Category 2 individual has not opened the mechanical switch to dispensing water, the detection is repeated. If it is detected again that only Category 2 individuals exist among the first group of individuals, the mechanical opening time of the hot water outlet is controlled to meet the next second time limit. This balances the freedom and safety of the individuals dispensing water within the sub-area, prevents excessively long single sessions, and avoids children or others using the remaining effective time of the second time limit to open the mechanical switch, thereby causing danger.

[0080] In a preferred embodiment of the present invention, the method further includes:

[0081] Step: When it is identified that the first person of the first category is between the first person of the second category and the drinking water equipment, the water flow from the hot water outlet of the drinking water equipment is restricted.

[0082] Considering that there are both Category 1 and Category 2 personnel among the first personnel, in addition to the situation where there are corresponding personnel of Category 1 in the reverse extension direction of the first direction, there may also be a situation where the corresponding personnel of Category 1 are between the first personnel of Category 2 and the water dispenser. This situation means that the corresponding personnel of Category 1 are in a relatively forward position, and their corresponding children, etc. are in a forward position compared to adults, etc. If they turn on the hot water switch first, there is a danger. At this time, it is also necessary to restrict their use of hot water, for example, by closing the electronic valve of the hot water outlet until the corresponding personnel of Category 1 appear in the reverse extension direction of the first direction. Then, proceed to steps S20-S22. Furthermore, the corresponding personnel of Category 2 can be guided to move forward by prompting, for example, by issuing a voice prompt such as "Please move forward, adults behind, to ensure normal hot water supply".

[0083] like Figure 4 As shown, in a preferred embodiment of the present invention, the categories of people within the area where the drinking water equipment is used are updated in real time specifically include:

[0084] Step S101: Obtain target detection information at the entrance of the usage area in real time, the target detection information including height detection information and identification detection information;

[0085] Step S102: Divide the height detection information according to whether it is greater than the set contact threshold to obtain the updated category of personnel newly entering the use area.

[0086] For height detection information, multiple sensors, such as distance sensors, are typically placed at equal intervals at the entrance of the area of ​​use, and the position of the sensor that obtains the highest valid detection data is used as the target detection information; or the height can be detected directly through 3D detection in visual inspection; this height can be limited to the interval height, and its accuracy does not need to be very high;

[0087] The identification information is generally extracted from the images captured by the vision camera;

[0088] The set contact threshold refers to the height at which the water outlet mechanical switch of the drinking water equipment can be touched; after dividing the height detection information according to whether it is greater than the set contact threshold, a first category and a second category can be obtained.

[0089] like Figure 5 As shown, combining the above steps, establishing the correspondence between the identifier and the category based on the personnel's identifier includes:

[0090] Step S111: Identify the updated category of the newly entered personnel in the area corresponding to the height detection information, wherein the updated category carries a first entry timestamp;

[0091] After dividing the height detection information according to the set contact threshold, the identification results in a first category and a second category, which are respectively the contact height below the set contact threshold and the contact height not below the set contact threshold; since the height detection information is timestamped when it is collected, the first entry timestamp is the timestamp of the collection directly assigned to the update category; indicating the collection time node to which the update category belongs;

[0092] Step S112: Organize the identification detection information to obtain the updated identification, which has a second entry timestamp;

[0093] Similarly, after organizing and dividing the identification detection information, the updated identification is obtained. Generally, each person's updated identification is different. After the identification detection information is divided, the updated identification is obtained. The updated identification includes at least one of the following: clothing color and clothing. If the clothing color and clothing are the same, the updated identification information can also include a blurred face outline. Similarly, the second entry timestamp is also the collection time node to which the updated identification belongs.

[0094] Step S113: Match update categories and update identifiers that have the same first entry timestamp and second entry timestamp, and generate a correspondence between identifiers and categories.

[0095] When collecting height detection information and identification detection information, the initial collection time and collection cycle are calibrated, and the collection is strictly simultaneous and synchronous by default, with the collection points located on the same side; therefore, as long as the first entry timestamp and the second entry timestamp are the same, the identification and category belong to the same person.

[0096] In this embodiment, a connection between the identifier and the category is established through a timestamp. Therefore, it is not necessary to identify the category of the person; only the identifier needs to be identified. The corresponding relationship with the identifier can be quickly queried to determine the category of the person corresponding to the identifier, which simplifies the process of identifying the category based on the contact height within the usage area.

[0097] like Figure 6 and Figure 7 As shown, in another preferred embodiment of the present invention, a water supply equipment monitoring system based on the Internet of Things (IoT) is provided, the system comprising:

[0098] The category update module 100 is used to update the category of personnel in the area where the drinking water equipment is used in real time. The category is divided according to the personnel's set contact threshold.

[0099] The correspondence establishment module 200 is used to establish a correspondence between the identifier and the category based on the identifier of the person;

[0100] The identification module 300 is used to identify the identification of the first person entering the sub-area where the drinking water equipment is located, and the area of ​​use includes the sub-area;

[0101] The query module 400 queries the corresponding relationship based on the identifier to obtain the category of the first person;

[0102] The restriction module 500 is used to restrict the water flow from the hot water outlet of the drinking water device when the first person is detected to be of the first category, wherein the first category includes persons whose contact height is below a set contact threshold.

[0103] When dealing with a large number of people in the area or new entrants, it is only necessary to confirm the identification of the person entering the sub-area to determine whether there is a potential operational hazard of the drinking water equipment. When the first person's category is only Category 1, the hot water outlet of the drinking water equipment is restricted, thereby providing indirect safety monitoring and protection for the relevant personnel.

[0104] like Figure 7 As shown, the system further includes an auxiliary opening module 600, which includes:

[0105] The coexistence category detection unit is used to identify the first direction formed by the corresponding personnel of the second category and the drinking water equipment when it is detected that a second category exists in the category of the first personnel, and if it is further determined that a first category still exists in the category of the first personnel, the contact height of the personnel in the second category is not lower than a set contact threshold.

[0106] The personnel detection unit is used to detect whether there is a first person of the first category in the reverse extension direction of the first direction;

[0107] The opening duration determination unit is used to determine the opening duration of the hot water outlet based on the change in the distance between the first person in the second category and the drinking water equipment if the condition is met.

[0108] Specifically, the activation duration determination unit is used for:

[0109] When the distance between the two sides reaches the first distance and gradually decreases, the effective number of times the hot water outlet is opened mechanically is a certain number of times or the opening time is the first time, and a water collection prompt is issued to assist the accompanying personnel behind.

[0110] While maintaining the same distance, detect whether the water fixtures entering the hot water outlet change.

[0111] If so, the effective number of times the mechanical opening of the hot water outlet is controlled will increase by one, or the opening time will increase by one duration.

[0112] In the above embodiments, as long as it is detected that only the second category exists in the first category of personnel again, the duration of mechanical opening of the hot water outlet is controlled to meet the next second duration. This can take into account the freedom and safety of the corresponding personnel to collect water in the sub-area, prevent the single time from being too long, and avoid children and others from using the remaining effective time of the second duration of water collection to cause danger.

[0113] The above embodiments of the present invention provide an IoT-based method for monitoring drinking water equipment, and based on this IoT-based method, an IoT-based system for monitoring drinking water equipment. The method involves real-time updating of the categories of personnel within the usage area of ​​the drinking water equipment, where each category is defined according to a set contact threshold. A correspondence is established between the personnel's identifiers and their categories. The system identifies the identifier of a first person entering a sub-area containing the drinking water equipment. The usage area includes sub-areas. The system queries the correspondence based on the identifier to obtain the category of the first person. When the first person's category is detected as only the first category, the system restricts the water flow from the hot water outlet of the drinking water equipment, where the contact height of the first category personnel is below a set contact threshold. When dealing with numerous personnel within the usage area or newly entering personnel, it is only necessary to confirm the identifier of the personnel entering the sub-area to determine whether there is a potential operational hazard with the drinking water equipment. Restricting the water flow from the hot water outlet of the drinking water equipment when the first person's category is only the first category provides indirect safety monitoring and protection for the relevant personnel.

[0114] In order for the above methods and systems to operate smoothly, the system may include more or fewer components than those described above, or combine certain components, or different components, in addition to the various modules mentioned above. For example, it may include input / output devices, network access devices, buses, processors, and memory.

[0115] The processor referred to can be a Central Processing Unit (CPU), or other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. A general-purpose processor can be a microprocessor or any conventional processor. This processor is the control center of the system, connecting various parts via various interfaces and lines.

[0116] The aforementioned memory can be used to store computer and system programs and / or modules. The aforementioned processor implements the various functions mentioned above by running or executing computer programs and / or modules stored in the memory, and by calling data stored in the memory. The memory may mainly include a program storage area and a data storage area.
