Description

Technical Field

[0001] The present application relates to the technical field of water service supervision, and particularly relates to a method, device, system, electronic device and storage medium for anti-freezing warning of water pipelines. Background Art

[0002] When the temperature is relatively low, the water meters and water supply pipelines of tap water are frozen or even cracked, which will bring great inconvenience to residents' water use. In cold winter or other times when the temperature is relatively low, it is particularly important to prevent the water meters and tap water pipelines from freezing.

[0003] In the related art, the anti-freezing warning for water pipelines is carried out based on past experience and current weather forecasts. For example, if the water meter pipelines were frozen in November in previous years, then anti-freezing measures will be implemented before November this year, such as wrapping the water meter pipelines with thermal insulation materials, checking the installed thermal insulation materials, emptying the pipelines that are not used recently, and asking users to keep a small flow of water continuously to ensure the water flow in the pipelines.

[0004] Predicting the temperature of water pipelines based on past experience and current weather forecasts is usually inaccurate. For example, in the case where a cold snap comes earlier than in previous years due to climate change, the weather forecast predicts the average temperature of the region, which has a large deviation from the temperature of the tap water pipelines. Due to the inaccurate prediction of the temperature of the tap water pipelines, the technical solutions for anti-freezing warning of tap water pipelines in the related art have problems of inaccurate and untimely warning.

[0005] The above statements are only used to provide background technical information related to the present application, and do not necessarily constitute prior art. Summary of the Invention

[0027] The technical solution provided by one aspect of the embodiments of the present application may include the following beneficial effects:

[0028] The anti-freezing warning method for water pipelines provided by the embodiments of the present application receives the temperature value sent by the intelligent water meter. This temperature value is detected by a temperature sensor connected to the intelligent water meter and sent to the intelligent water meter. If the temperature value received within the preset duration meets the determination condition of the first-level anti-freezing warning point, the position of the intelligent water meter is marked as the first-level anti-freezing warning point.

Compared with the prior art solution of anti-freezing warning for water pipelines based on past experience and current weather forecasts, the anti-freezing warning method of the embodiments of the present application improves the timeliness and accuracy of anti-freezing warning by making hierarchical anti-freezing warning marks on the intelligent water meter according to the temperature value sent by the intelligent water meter, and overcomes the technical defects of untimely and inaccurate anti-freezing warning for water pipelines in the prior art based on past experience and current weather forecasts.

[0029] The above description is only an overview of the technical solution of the embodiments of the present application. In order to be able to understand the technical means of the embodiments of the present application more clearly, it can be implemented according to the content of the specification. And in order to make the above and other purposes, features and advantages of the embodiments of the present application more obvious and understandable, the following specifically illustrates the embodiments of the present application.

[0037] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0038] Those skilled in the art can understand that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as the general understanding of those of ordinary skill in the technical field to which the present application belongs. It should also be understood that terms such as those defined in a general dictionary should be understood to have a meaning consistent with the meaning in the context of the prior art, and will not be interpreted in an idealized or overly formal sense unless specifically defined as here.

[0039] In the related art, the anti-freezing warning for water pipelines is carried out based on past experience and current weather forecasts. Usually, it is inaccurate to predict the temperature of water pipelines based on past experience and current weather forecasts. Therefore, the accuracy of the anti-freezing warning in the related art is low and the timeliness is poor.

[0040] In view of the technical problems existing in the related art, the anti-freezing warning method for water pipelines provided by the embodiments of the present application receives the temperature value sent by the intelligent water meter. This temperature value is detected by the temperature sensor connected to the intelligent water meter and sent to the intelligent water meter. If the temperature value received within the preset duration meets the determination condition of the first-level anti-freezing warning point, the position of the intelligent water meter is marked as the first-level anti-freezing warning point. If the temperature value received within the preset duration meets the determination condition of the (i + 1)-th level anti-freezing warning point and does not meet the determination condition of the i-th level anti-freezing warning point, the position of the intelligent water meter is marked as the (i + 1)-th level anti-freezing warning point, where i is a positive integer, 1 ≤ i < n, and n is a positive integer representing the preset number of levels of anti-freezing warning points. Compared with the technical solution of the related art for carrying out anti-freezing warning on water pipelines based on past experience and current weather forecasts, the anti-freezing warning method of the embodiments of the present application improves the timeliness and accuracy of the anti-freezing warning by making a hierarchical anti-freezing warning mark for the intelligent water meter according to the temperature value sent by the intelligent water meter, and overcomes the technical defects of the related art that the anti-freezing warning for water pipelines based on past experience and current weather forecasts is not timely and inaccurate.

[0041] Figure 1 The figure is a schematic diagram of the application scenario of the water pipeline anti-freezing warning method according to the embodiment of the present application. The water pipeline anti-freezing warning method according to the embodiment of the present application is applied to the server of the water pipeline anti-freezing warning system. The water pipeline anti-freezing warning system includes a server and at least one intelligent water meter communicatively connected to the server. The server receives the temperature value sent by the intelligent water meter. If the temperature value received within the preset duration meets the determination condition of the first-level anti-freezing warning point, the position of the intelligent water meter is marked as the first-level anti-freezing warning point. If the temperature value received within the preset duration meets the determination condition of the (i + 1)-th level anti-freezing warning point and does not meet the determination condition of the i-th level anti-freezing warning point, the position of the intelligent water meter is marked as the (i + 1)-th level anti-freezing warning point, where i is a positive integer, 1 ≤ i < n, and n is a positive integer representing the preset number of levels of the anti-freezing warning points. The temperature value sent by the intelligent water meter is detected by a temperature sensor connected to the intelligent water meter and sent to the intelligent water meter, and the intelligent water meter is arranged on the water pipeline.

[0042] It can be understood that the terms "first", "second", "third", etc. in this article are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance. It should also be understood that although the terms "first", "second", "third", etc. are used to describe various elements in some embodiments, these elements should not be limited by these terms, and these terms are only used to distinguish various elements.

[0043] Next, a water pipeline anti-freezing warning method according to an embodiment of the present application will be described with reference to the accompanying drawings.

[0044] Reference Figure 2 As shown, an embodiment of the present application provides a water pipeline anti-freezing warning method, which is applied to a server. The method may include steps S10 to S30:

[0045] S10. Receive the temperature value sent by the intelligent water meter.

[0046] This temperature value is detected by a temperature sensor connected to the intelligent water meter and sent to the intelligent water meter, and the intelligent water meter sends out the received temperature value. The intelligent water meter is arranged on the water pipeline. A plurality of intelligent water meters connected with temperature sensors are installed on the water meter pipeline. The intelligent water meter includes a communication module and can send the temperature value through the communication module.

[0047] When installing an intelligent water meter, the installation location of the intelligent water meter is recorded in the server. The installation location of the intelligent water meter can be represented by, for example, longitude and latitude. The intelligent water meter can include a positioning device, and the location of the intelligent water meter can be obtained through the positioning device. Alternatively, when installing the intelligent water meter, after the staff uses a positioning device to obtain the location of the intelligent water meter, the location of the intelligent water meter can be sent to the server. The location of the intelligent water meter can be displayed on an electronic map.

[0048] The intelligent water meter is installed on the water pipeline, and the temperature sensor connected to the intelligent water meter collects the temperature inside or outside the water pipeline in real time. If the probe of the temperature sensor is set outside the water pipeline, the temperature outside the water pipeline is collected; if the probe of the temperature sensor is set inside the water pipeline, the water temperature inside the water pipeline is collected. The temperature value detected by the temperature sensor is beneficial to improving the accuracy and timeliness of determining the anti-freezing warning level according to the temperature of the intelligent water meter.

[0049] In some embodiments, the temperature values sent by the intelligent water meter include the temperature values periodically sent by the intelligent water meter and the temperature values sent in real time.

[0050] The temperature value sent in real time is the real-time temperature value determined by the intelligent water meter through comparison and sent in real time and lower than the preset temperature threshold. Specifically, after the temperature sensor connected to the intelligent water meter detects the real-time temperature value, it transmits it to the main control module of the intelligent water meter. The main control module in the intelligent water meter compares the real-time temperature value with the preset temperature threshold. If the real-time temperature value is lower than the preset temperature threshold, the intelligent water meter immediately sends the real-time temperature value to the server through the communication module, thereby improving the timeliness of the transmission of lower-value temperature data. The preset temperature threshold can be set according to actual application needs. The preset temperature threshold is usually set relatively low. When the temperature sensor detects that the real-time temperature value is lower than the preset temperature threshold, it usually indicates that there may be a risk of the water pipeline being frozen at the current temperature. Therefore, the intelligent water meter immediately sends the real-time temperature value from the temperature sensor to the server through the communication module, so that the server can make a judgment in time and improve the timeliness of the transmission of lower-value temperature data.

[0051] For example, the intelligent water meter compares the collected real-time temperature value with the severe anti-freezing warning value X (the severe anti-freezing warning value is the temperature threshold of the first-level anti-freezing warning point, which can be preset by the intelligent water meter or preset by the server). If the real-time temperature value is lower than the severe anti-freezing warning value X, the collected real-time temperature value is immediately reported to the server through communication. If the real-time temperature value is not lower than the severe anti-freezing warning value X, the intelligent water meter periodically sends the collected temperature value to the server through communication (for example, once per hour or once per day).

[0052] S20. If the temperature values received within the preset duration meet the determination conditions for the first-level anti-freezing warning point, mark the location of the intelligent water meter as the first-level anti-freezing warning point.

[0053] Specifically, the determination conditions for the first-level anti-freezing warning point include that the cumulative number of temperature values less than the first temperature threshold received within the preset duration reaches the first preset number, and the point corresponding to the current moment on the historical temperature-time relationship curve is located on the curve segment where the temperature decreases as time progresses.

[0054] The historical temperature-time relationship curve can be, for example, a curve established in a coordinate system with time as the horizontal axis and temperature values as the vertical axis. The curve segment where the temperature decreases as time progresses is the part of the curve where the temperature values monotonically decrease with time.

[0055] For example, assume that the preset duration is 24 hours, the first temperature threshold is 2°C, and the first preset number is 30. If the cumulative number of temperature values less than 2°C received within 24 hours reaches 30 (i.e., cumulative greater than or equal to 30), mark the location of the intelligent water meter as the first-level anti-freezing warning point.

[0056] The method of marking the location of the intelligent water meter as the first-level anti-freezing warning point can include, for example, marking and displaying the location of the intelligent water meter on an electronic map with a preset marking symbol, or outputting in text form the information that the location of the intelligent water meter is marked as the first-level anti-freezing warning point, etc.

[0057] S30. If the temperature values received within the preset duration meet the determination conditions for the (i + 1)-th level anti-freezing warning point and do not meet the determination conditions for the i-th level anti-freezing warning point, mark the location of the intelligent water meter as the (i + 1)-th level anti-freezing warning point, where i is a positive integer, 1 ≤ i < n, n is a positive integer, and n represents the preset number of levels of anti-freezing warning points.

[0058] For example, when n = 2, there are two levels of anti-freezing warning points, namely the first-level anti-freezing warning point and the second-level anti-freezing warning point. The first-level anti-freezing warning point can be called the severe anti-freezing warning risk point, and the second-level anti-freezing warning point can be called the general anti-freezing warning risk point. Another example, when n = 4, it means that the preset number of levels of anti-freezing warning points is 4, that is, there are four levels of anti-freezing warning points, namely the first-level anti-freezing warning point, the second-level anti-freezing warning point, the third-level anti-freezing warning point, and the fourth-level anti-freezing warning point. Specifically, the value of n can be set according to the actual application needs.

[0059] In some embodiments, the determination condition for the i-th level of anti-freezing warning point includes that the cumulative number of temperature values less than the i-th temperature threshold received within the preset time duration reaches the i-th preset number, and the point corresponding to the current moment on the historical temperature-time relationship curve is located on the curve segment where the temperature decreases as time progresses, where the i-th temperature threshold is less than the (i + 1)-th temperature threshold.

[0060] The first temperature threshold, the second temperature threshold,..., the n-th temperature threshold are all pre-set temperature thresholds, and satisfy the first temperature threshold < the second temperature threshold <... < the n-th temperature threshold. The first preset number, the second preset number,..., the n-th preset number are all pre-set values respectively. The meaning of reaching the i-th preset number cumulatively is that the cumulative value is greater than or equal to the i-th preset number.

[0061] For example, when n is 4, the first temperature threshold, the second temperature threshold, the third temperature threshold, and the fourth temperature threshold corresponding to the first-level anti-freezing warning point, the second-level anti-freezing warning point, the third-level anti-freezing warning point, and the fourth-level anti-freezing warning point can be 2°C, 3°C, 5°C, and 8°C in sequence. The determination condition for the second-level anti-freezing warning point includes that the cumulative number of temperature values less than the second temperature threshold of 3°C received within the preset time duration (such as 24 hours) reaches the second preset number (such as 50), and the point corresponding to the current moment on the historical temperature-time relationship curve is located on the curve segment where the temperature decreases as time progresses.

[0062] There are n preset levels of anti-freezing warning points in total, and each preset level corresponds to a pre-set temperature threshold, so as to refine the division of the levels of anti-freezing warning points and further improve the accuracy of anti-freezing warning.

[0063] In a specific example, there are two levels of anti-freezing warning points, namely the first-level anti-freezing warning point and the second-level anti-freezing warning point. The first-level anti-freezing warning point can be called a severe anti-freezing warning risk point, and the second-level anti-freezing warning point can be called a general anti-freezing warning risk point.

[0064] If the historical temperature of a certain intelligent water meter in the same period is in a downward trend segment (the downward trend segment is the curve segment where the temperature decreases as time progresses), and the cumulative number of temperature values reported by the intelligent water meter received by the server and lower than the severe anti-freezing warning value X within the preset time duration (such as 24 hours) reaches the first preset number of times, then the intelligent water meter is marked as a severe anti-freezing warning risk point. For example, if the current date is December 15th, if December 11th to December 21st of last year all belong to the temperature downward trend segment, that is, the historical temperature corresponding to December 15th of last year is in the downward trend segment, and the cumulative number of temperature values received in the recent 24 hours and lower than the severe anti-freezing warning value of 3°C reaches the first preset number of times, such as 5 times, then the location where the intelligent water meter is located is marked as a severe anti-freezing warning risk point.

[0065] If a smart water meter is not a severe anti-freezing warning risk point, and the historical temperature of the smart water meter in the same period is in a downward trend segment (the downward trend segment is the curve segment where the temperature decreases as time progresses), and the temperature values reported in the most recent preset number of times are all lower than the general anti-freezing warning value Y (the general anti-freezing warning value is the temperature threshold of the second-level anti-freezing warning point), then mark the location where the smart water meter is located as a general anti-freezing warning risk point.

[0066] For example, if the current date is December 12th, and from December 1st to December 31st of last year all belonged to the temperature downward trend segment, that is, the historical temperature corresponding to December 12th of last year was in the downward trend segment, and the cumulative number of temperature values lower than the general anti-freezing warning value of 5°C received within the preset duration (such as 24 hours) reached the second preset number of times (such as 10 times), then mark the location where the smart water meter is located as a general anti-freezing warning risk point.

[0067] The method of marking the location of the smart water meter as the i-level anti-freezing warning point can include, for example, marking the location of the smart water meter on the electronic map with a preset marking symbol as the i-level anti-freezing warning point, or marking the location of the smart water meter presented in text form with a preset marking format as the i-level anti-freezing warning point, etc.

[0068] Marking the location of the smart water meter on the electronic map with a preset marking symbol as the i-level anti-freezing warning point can include, for example: adding a preset marking symbol corresponding to the i-level anti-freezing warning point, such as an exclamation mark or other symbols, to the location point of the smart water meter on the electronic map, so as to mark it as the i-level anti-freezing warning point.

[0069] Marking the location of the smart water meter presented in text form with a preset marking format as the i-level anti-freezing warning point can include, for example: displaying the text representing the location of the smart water meter on the display screen in a preset font and / or preset color corresponding to the i-level anti-freezing warning point, or adding symbols such as a square box or an underline corresponding to the i-level anti-freezing warning point to the text representing the location of the smart water meter, so as to indicate that the location of the smart water meter is the i-level anti-freezing warning point.

[0070] The marked i-level anti-freezing warning point is used to achieve anti-freezing warning for the water pipeline. The information of the marked i-level anti-freezing warning point can prompt the staff that the location of the smart water meter is the i-level anti-freezing warning point (for example, the preset marking symbol of the i-level anti-freezing warning point is displayed in a more prominent form on the display screen, so as to play a warning role), thereby realizing the warning function. After obtaining the information of the i-level anti-freezing warning point, the staff can take corresponding anti-freezing measures.

[0071] Reference Figure 3As shown, in some embodiments, the anti-freezing warning method for the water pipeline may further include step S40: S40. If the temperature values received within a preset time duration do not meet the determination conditions of any anti-freezing warning point, mark the position of the intelligent water meter as a non-anti-freezing warning point.

[0072] In some embodiments, the anti-freezing warning method for the water pipeline may further include: when the proportion of the number of the i-th level anti-freezing warning points in a region reaches the i-th preset proportion, send the i-th level anti-freezing warning information and mark the region as the i-th level anti-freezing warning region.

[0073] The i-th level anti-freezing warning information may be, for example, an audible and visual alarm message and / or a message sent to the mobile terminal (such as a mobile phone) of relevant personnel, such as a text message. The audible and visual alarm message includes an audible alarm signal and a light signal, and may include, for example, an audible alarm message emitted by a speaker or a buzzer and a light-emitting signal of an LED flash lamp. For example, in region A, if the proportion of the number of the first-level anti-freezing warning points reaches the first preset proportion of 10%, send the first-level anti-freezing warning information and mark region A as the first-level anti-freezing warning region.

[0074] It can be understood that the first preset proportion, the second preset proportion,..., the n-th preset proportion are respectively preset in advance according to actual application needs. When the proportion of the number of the i-th level anti-freezing warning points in a region reaches the i-th preset proportion, send the i-th level anti-freezing warning information and mark the region as the i-th level anti-freezing warning region. Judging the anti-freezing warning level according to the preset proportion greatly improves the accuracy of anti-freezing warning judgment.

[0075] In some embodiments, if a region does not belong to any level of anti-freezing warning region, mark the region as a non-anti-freezing warning region. When the proportion of the number of the first-level anti-freezing warning points in the non-anti-freezing warning region reaches the first preset proportion, send the first-level anti-freezing warning information and mark the non-anti-freezing warning region as the first-level anti-freezing warning region. When the non-anti-freezing warning region directly becomes the first-level anti-freezing warning region, it indicates that the temperature drops relatively rapidly, and thus this region needs to be focused on. For example, the first-level anti-freezing warning information and an emergency anti-freezing warning information may be sent, and the non-anti-freezing warning region is marked as the first-level anti-freezing warning region and the emergency anti-freezing warning region, or only the emergency anti-freezing warning information may be sent, and the non-anti-freezing warning region is marked as the emergency anti-freezing warning region.

[0076] In some embodiments, the water pipeline anti-freezing warning method may further include: displaying the i-th level anti-freezing warning points and the i-th level anti-freezing warning areas on an electronic map. Displaying the anti-freezing warning points and areas of each level on the electronic map facilitates the staff to obtain relevant information more intuitively. For example, the electronic map can be displayed on the application APP on the staff's smartphone, and the i-th level anti-freezing warning points and the i-th level anti-freezing warning areas are marked in red on the electronic map.

[0077] In some embodiments, the water pipeline anti-freezing warning method may further include: if an ice-covered intelligent water meter appears, retrieving the temperature value sent by the ice-covered intelligent water meter last time; adjusting the temperature threshold of the first-level anti-freezing warning point to be greater than or equal to the last-sent temperature value, and adjusting the temperature threshold of the (i + 1)-th level anti-freezing warning point according to the fact that the i-th temperature threshold is less than the (i + 1)-th temperature threshold.

[0078] Specifically, the intelligent water meter cannot send the temperature value after icing. If the intelligent water meter is frozen, it means that the last received temperature value is greater than the temperature threshold of the first-level anti-freezing warning point. Therefore, there is not enough time reserved for warning before the intelligent water meter freezes. Since the temperature threshold of the first-level anti-freezing warning point is the lowest among the anti-freezing warning points of each level and is closest to the freezing temperature, at least the temperature threshold of the first-level anti-freezing warning point needs to be increased. The temperature thresholds of multiple levels of anti-freezing warning points can be increased, but it is necessary to ensure that the i-th temperature threshold is still less than the (i + 1)-th temperature threshold after the increase. After adjusting the temperature threshold of the first-level anti-freezing warning point, a larger temperature threshold is obtained. For example, the original temperature threshold is 2°C, and the larger temperature threshold is 2.8°C. Thus, the location where the intelligent water meter is located can be marked as the first-level anti-freezing warning point when the larger temperature threshold is reached, so as to timely remind relevant personnel to take corresponding anti-freezing measures.

[0079] For example, for an ice-covered intelligent water meter, record the icing time of the intelligent water meter. The server increases the severe anti-freezing warning value X (i.e., the temperature threshold of the first-level anti-freezing warning point) and the general anti-freezing warning value Y (i.e., the temperature threshold of the second-level anti-freezing warning point), and ensures that the severe anti-freezing warning value X is lower than the general anti-freezing warning value Y. For example, the time when the last temperature value sent by the intelligent water meter is received can be used as the first time, and the first time is used as the icing time of the intelligent water meter. Or, the second time obtained by adding the aforementioned preset duration to the time when the last temperature value sent by the intelligent water meter is received can be used as the icing time of the intelligent water meter. Or any moment between the first time and the second time can be selected as the icing time of the intelligent water meter.

[0080] Assume that the first temperature threshold is 2°C. Then, the temperature value sent by the frozen intelligent water meter for the last time must be higher than this first temperature threshold by 2°C. Therefore, it is impossible to mark this intelligent water meter as a first-level anti-freezing warning point, resulting in the failure to take anti-freezing measures in time to prevent this intelligent water meter from freezing. At this time, the temperature threshold of the first-level anti-freezing warning point can be adjusted from 2°C to the temperature value sent for the last time or a temperature value slightly larger than the temperature value sent for the last time, and the temperature threshold of the (i + 1)-th level anti-freezing warning point is adjusted according to the fact that the i-th temperature threshold is less than the (i + 1)-th temperature threshold.

[0081] The water pipeline anti-freezing warning method according to the embodiment of the present application marks the intelligent water meter with different levels of anti-freezing warnings according to the temperature values sent by the intelligent water meter, making the anti-freezing warning levels more refined, improving the timeliness and accuracy of the anti-freezing warning, and overcoming the technical defects of untimely and inaccurate anti-freezing warnings for water pipelines based on past experience and current weather forecasts in the related art.

[0082] Reference Figure 4 As shown in the figure, another embodiment of the present application provides a water pipeline anti-freezing warning device, which is applied to a server. The device includes:

[0083] A receiving module, configured to receive the temperature value sent by the intelligent water meter. The temperature value is detected by a temperature sensor connected to the intelligent water meter and sent to the intelligent water meter. The intelligent water meter is arranged on the water pipeline;

[0084] A marking and warning module, configured to mark the position of the intelligent water meter as a first-level anti-freezing warning point if the temperature value received within a preset duration meets the determination condition of the first-level anti-freezing warning point; and,

[0085] If the temperature value received within a preset duration meets the determination condition of the (i + 1)-th level anti-freezing warning point and does not meet the determination condition of the i-th level anti-freezing warning point, mark the position of the intelligent water meter as the (i + 1)-th level anti-freezing warning point, where i is a positive integer, 1 ≤ i < n, n is a positive integer, and n represents the preset number of levels of anti-freezing warning points.

[0086] Exemplarily, the determination condition of the i-th level anti-freezing warning point includes that the cumulative number of temperature values less than the i-th temperature threshold received within the preset duration reaches the i-th preset number, and the point corresponding to the current moment on the historical temperature-time relationship curve is located on the curve segment where the temperature decreases as time progresses, and the i-th temperature threshold is less than the (i + 1)-th temperature threshold.

[0087] Exemplarily, the temperature values sent by the intelligent water meter include the temperature values periodically sent by the intelligent water meter and the temperature values sent in real time; the temperature values sent in real time are the real-time temperature values lower than the preset temperature threshold determined and sent in real time by the intelligent water meter after comparison.

[0088] Exemplarily, the marking and warning module can also be used to: if the temperature values received within a preset time period do not meet the determination conditions of any level of anti-freezing warning point, mark the location of the intelligent water meter as a non-anti-freezing warning point.

[0089] Exemplarily, the marking and warning module can also be used to: according to the proportion of the number of the i-th level anti-freezing warning points in an area reaching the i-th preset ratio, send the i-th level anti-freezing warning information and mark the area as the i-th level anti-freezing warning area.

[0090] Exemplarily, the marking and warning module can also be used to: if there is an intelligent water meter with ice formation, retrieve the temperature value sent by the iced intelligent water meter for the last time; adjust the temperature threshold of the first-level anti-freezing warning point to be greater than or equal to the temperature value sent for the last time, and adjust the temperature threshold of the (i + 1)-th level anti-freezing warning point according to the fact that the i-th temperature threshold is less than the (i + 1)-th temperature threshold.

[0091] The anti-freezing warning device of the embodiment of the present application improves the timeliness and accuracy of anti-freezing warning by performing anti-freezing warning marking at different levels on the intelligent water meter according to the temperature values sent by the intelligent water meter, and overcomes the technical defects of untimely and inaccurate anti-freezing warning of water pipelines based on past experience and current weather forecasts in the related art.
