Description

Technical Field

[0001] The present invention relates to the technical field of secondary water supply pressure regulation, and more specifically to an artificial intelligence-based secondary water supply pressure early warning regulation system and method. Background Art

[0002] Secondary water supply refers to the form in which units or individuals store and pressurize urban public water or self-built water supply, and then supply it to users or for their own use through pipelines. Secondary water supply is mainly established to compensate for the lack of pressure in municipal water supply pipelines and to ensure water supply for people living in high-rise buildings. Secondary water supply provides domestic water for residents on the seventh floor and above;

[0003] When conducting secondary water supply, the secondary water supply can remove impurities, hardness substances, organic matter, etc. in the tap water through filtering, disinfection and other treatment methods, improve the water quality, and make the water quality cleaner and healthier. The secondary water supply can treat the tap water again, remove harmful substances and microorganisms in the tap water, ensure the safety of the water supply, and avoid water quality problems caused by pollutants in the tap water. In order to ensure the smooth progress of the secondary water supply, the water pressure of the secondary water supply needs to be regulated, but the traditional secondary water supply water pressure regulation system has the following problems:

[0004] When regulating the water pressure of the secondary water supply, it is generally necessary to set up a booster device on each floor to ensure that the secondary water supply can adapt to different floors. Therefore, each floor needs to be pressurized and tested in real time. However, the water pressure required for adjacent floors is slightly different, so pressurizing them all will cause a waste of resources. When a problem occurs on a certain floor, no adjustments can be made at this time, so there will be a water outage on that floor.

[0005] When pressurizing the water supply, sufficient pressure is required to ensure that the water is delivered to the floor. However, when the applied pressure meets the requirements, it will be affected by the conditions in the water pipes. For example, if there is a blockage in the water pipes, the water supply may not be normal. However, the traditional control system cannot detect the conditions in the water pipes, and thus cannot ensure normal water supply. Summary of the invention

[0006] In order to overcome the above-mentioned defects of the prior art, the implementation regulations of the present invention provide a secondary water supply water pressure early warning and control system and method based on artificial intelligence to solve the technical problems raised in the background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a secondary water supply water pressure early warning and control system based on artificial intelligence, comprising a detection unit, an early warning unit, an analysis unit, a central control unit, a pressurizing unit, a maintenance unit, a fault unit and a floor unit, wherein the detection unit is used to detect information in the secondary water supply pipe and send it to the analysis unit, the analysis unit receives data from the detection unit, processes the data to form a judgment value U and then sends it to the early warning unit, the early warning unit receives the judgment value U and sends an instruction to the central control unit, the central control unit receives the instruction and instructs the maintenance unit to perform maintenance work, and the central control unit controls the pressurizing unit to perform pressurization work on the secondary water supply, when the pressure is insufficient, the fault unit receives the information sent by the central control unit, makes a judgment and then sends an instruction to the maintenance unit, the maintenance unit receives the instructions from the central control unit and the fault unit and performs maintenance work, and the floor unit is used to perform floor zoning;

[0008] The detection unit detects the water pressure before the secondary water supply is pressurized, the water pressure after the pressurization, and the flow rate of the water before it flows to the user, and generates the unpressurized water pressure data YQ, the pressurized water pressure data YH, and the water flow rate data LS, and then sends them to the analysis unit. The analysis unit receives the water pressure data YQ, the pressurized water pressure data YH, and the water flow rate data LS, and generates a judgment value U after data processing. The processing formula of the judgment value U is: In the formula, U is the calculated judgment value, YS is the preset flow rate of water before it flows to the user, k1 and k2 are weights, and 0≤k1≤1, 0≤k2≤1, k1+k2=1, sgn is an integer function, and the analysis unit sends the calculated judgment value U to the early warning unit.

[0009] In a preferred embodiment, the early warning unit receives a judgment value U. When the judgment value U is zero, a first instruction is sent to the central control unit. When the early warning unit receives a judgment value U and it is a positive number, it is compared with a threshold value Y. When the judgment value U is greater than or equal to the threshold value Y, a second instruction is sent to the central control unit. When the judgment value U is less than the threshold value Y, a second instruction is sent to the central control unit.

[0010] In a preferred embodiment, the central control unit receives the first instruction and sends a dredging command to the maintenance unit. The maintenance unit receives the dredging command and reminds the maintenance personnel to perform water pipe maintenance work through the terminal device. The central control unit sends the floor information generated by the first instruction together with the dredging command to the terminal device.

[0011] In a preferred embodiment, the central control unit receives a second instruction, and the water pressure of the secondary water supply is normal, so the central control unit does not send a command. The central control unit receives a third instruction, and the water pressure of the secondary water supply is insufficient, so the central control unit sends a pressurization command to the pressurizing unit, and the pressurizing unit receives the pressurization instruction and performs pressurization processing.

[0012] In a preferred embodiment, the pressurization unit includes a regional pressurization module, a floor pressurization module and a control module. The regional pressurization module is used to pressurize each floor in the floor unit, and the floor pressurization module is used for pressurization in each floor. The regional pressurization module is in a working state, and the floor pressurization module is in a standby state. The control module receives the pressurization command sent by the central control unit and controls the regional pressurization module to perform pressurization operations. The control module receives three pressurization commands in succession within ten minutes, and the control module controls the regional pressurization module and the floor pressurization module to perform pressurization operations simultaneously and sends a fault command to the central control unit.

[0013] In a preferred embodiment, the control module sends a fault instruction to the central control unit, the central control unit receives the fault instruction and extracts the floor information of the control module that sends the fault instruction, the floor information comes from the detection unit, and the floor information content includes unpressurized water pressure data YQ, pressurized water pressure data YH and water flow rate data LS, and the central control unit sends the floor information to the fault unit.

[0014] In a preferred embodiment, the fault unit includes a display module and a judgment module. The display module receives the floor information sent by the central control unit and displays it on its display screen. The judgment module receives the floor information sent by the central control unit and compares the unpressurized water pressure data YQ, the pressurized water pressure data YH and the water flow rate data LS with the threshold. The threshold includes the first water pressure DY, the second water pressure DE and the standard water flow rate SD, so as to judge the problem in the water pipe of the secondary water supply, and the fault unit sends a maintenance instruction to the maintenance unit.

[0015] In a preferred embodiment, when the judgment module performs threshold comparison, the first problem is: when the unpressurized water pressure data YQ is less than the first water pressure DY, the inlet water pressure is too low; the second problem is: when the pressurized water pressure data YH is lower than the second water pressure DE, the pressurized water pressure is too low; the third problem is: when the water flow rate data LS is less than the standard water flow rate SD, the water flow is too slow, and the judgment unit sends the problem to the display unit and displays it on the display screen of the display unit.

[0016] In a preferred embodiment, the floor unit includes a statistical module and a partitioning module. The statistical module counts the number of floors in the building and sends the statistical results to the partitioning module. The partitioning module partitions the floors seven and above, with every three floors divided into one zone. The first zone is 7-9 floors, the second zone is 10-12 floors, the third zone is 13-15 floors, and so on. When there is only one floor left at the top of the floor, it is combined with the next floor into one zone. When there are two floors left at the top of the floor, these two floors are a separate zone.

[0017] A secondary water supply water pressure early warning and control method based on artificial intelligence comprises the following steps:

[0018] Step S1, the detection unit detects the information in the secondary water supply pipe and sends it to the analysis unit, the analysis unit receives the data of the detection unit and forms a determination value U;

[0019] Step S2: the early warning unit receives the determination value U and compares it with the threshold value, and then sends an instruction to the central control unit. The central control unit receives the instruction and instructs the maintenance unit to perform maintenance work;

[0020] Step S3, the central control unit controls the pressurizing unit to perform pressurizing work on the secondary water supply. When the pressure is insufficient, the fault unit receives the information sent by the central control unit, makes a judgment, and then sends a command to the maintenance unit;

[0021] Step S4: The maintenance unit receives instructions from the central control unit and the faulty unit and performs maintenance work. The technical effects and advantages of the present invention are as follows:

[0022] 1. The present invention is provided with a detection unit, which generates unpressurized water pressure data YQ, pressurized water pressure data YH and water flow rate data LS and then sends them to the analysis unit to collect three kinds of data. Therefore, when judging the water pressure, when the water pressure is sufficient and the water pipe is blocked, it can be judged by the water flow rate data LS. Therefore, the water pressure detection and regulation of the secondary water supply in the present application are more accurate;

[0023] 2. The present invention is provided with a pressurizing unit, which is provided with a regional pressurizing module and a floor pressurizing module to perform pressurizing operation together. The regional pressurizing module is in working state and performs pressurizing operation on three floors of each zone. Therefore, one pressurizing module performs pressurizing operation on three floors at the same time, saving resources. The floor pressurizing module will pressurize the floor with insufficient water pressure, so that the current floor can meet the pressure demand;

[0024] 3. The present invention divides the floor into zones through a zoning module. At this time, the high-rise floors that need secondary water supply will be zoned for treatment, thereby reducing the problem of incoordination in various aspects when each floor needs to be pressurized separately in the traditional way. The pressure required between two adjacent floors is not much different, so it is a waste of resources when pressurizing them separately. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are only examples. The secondary water supply water pressure early warning and control system and method based on artificial intelligence involved in the present invention are not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0028] Reference Figure 1 The present invention provides a secondary water supply pressure early warning and control system based on artificial intelligence, including a detection unit, an early warning unit, an analysis unit, a central control unit, a pressurizing unit, a maintenance unit, a fault unit and a floor unit. The detection unit is used to detect the information in the secondary water supply pipe and send it to the analysis unit. The analysis unit receives the data of the detection unit, processes the data to form a judgment value U and then sends it to the early warning unit. The early warning unit receives the judgment value U and sends an instruction to the central control unit. The central control unit receives the instruction and instructs the maintenance unit to perform maintenance work, and the central control unit controls the pressurizing unit to perform the pressurizing work of the secondary water supply. When the pressure is insufficient, the fault unit receives the information sent by the central control unit, makes a judgment and then sends an instruction to the maintenance unit. The maintenance unit receives the instructions of the central control unit and the fault unit and performs maintenance work. The floor unit is used to perform floor zoning;

[0029] The detection unit detects the water pressure before the secondary water supply is pressurized, the water pressure after the pressurization, and the flow rate of the water before it flows to the user, and generates the unpressurized water pressure data YQ, the pressurized water pressure data YH, and the water flow rate data LS, and then sends them to the analysis unit. The analysis unit receives the water pressure data YQ, the pressurized water pressure data YH, and the water flow rate data LS, and generates a judgment value U after data processing. The processing formula of the judgment value U is: In the formula, U is the calculated judgment value, YS is the preset flow rate of water before it flows to the user, k1 and k2 are weights, and 0≤k1≤1, 0≤k2≤1, k1+k2=1, sgn is an integer function, and the analysis unit sends the calculated judgment value U to the early warning unit.

[0030] In the embodiment of the present application, the detection unit generates unpressurized water pressure data YQ, pressurized water pressure data YH and water flow rate data LS and sends them to the analysis unit to collect three kinds of data. Therefore, when water pressure is judged, when the water pressure is sufficient and the water pipe is blocked, it can be judged by the water flow rate data LS. Therefore, the water pressure detection and regulation of the secondary water supply in the present application are more accurate.

[0031] Furthermore, the early warning unit receives a judgment value U. When the judgment value U is zero, a first instruction is sent to the central control unit. When the early warning unit receives the judgment value U and it is a positive number, it is compared with the threshold value Y. When the judgment value U is greater than or equal to the threshold value Y, a second instruction is sent to the central control unit. When the judgment value U is less than the threshold value Y, a second instruction is sent to the central control unit. In the calculation formula of the judgment value U of the present application, sgn is an integer function, and when it takes values, when 0 is input, sgn will output 0, when any number greater than zero is input, it will output 1, and when any number less than zero is input, it will output -1. Therefore, when the detected water flow rate is less than the preset flow rate, sgn will output -1. When sgn outputs -1 and increases with the previous 1, the value of the judgment value U is zero. At this time, it indicates that there is a blockage in the water pipe, not a pressurization problem. Therefore, the instruction is directly sent to the central control unit, ignoring the blockage of the water pipe and causing errors in water pressure detection.

[0032] Furthermore, the central control unit receives the first instruction and sends a dredging command to the maintenance unit. The maintenance unit receives the dredging command and reminds the maintenance personnel to perform water pipe maintenance work through the terminal device, and the central control unit sends the floor information generated by the first instruction together with the dredging command to the terminal device. The first instruction indicates that there is a blockage in the water pipe at this time, rather than insufficient water supply pressure. At this time, the floor information where the blocked water pipe is located is sent to the maintenance unit. At this time, the maintenance personnel will learn this information through the terminal device in their hands, so they can quickly rush to the maintenance site to dredge the water pipes and ensure the smooth secondary water supply in the floor.

[0033] Furthermore, the central control unit receives the second instruction, at which time the water pressure of the secondary water supply is normal, and the central control unit does not send a command. The central control unit receives the third instruction, at which time the water pressure of the secondary water supply is insufficient, and the central control unit sends a pressurization command to the pressurization unit, and the pressurization unit accepts the pressurization instruction and performs pressurization processing. When the central control unit receives the second instruction, it determines that the value U is greater than or equal to the threshold value Y, and therefore the water pressure of the secondary water supply is normal. At this time, the central control unit continues to control each unit to perform normal work. When the central control unit receives the third instruction, it indicates that the water pressure is not enough for users to use, and therefore a pressurization command needs to be issued to the pressurization unit, and the pressurization unit performs pressurization processing, thereby ensuring that each layer has sufficient pressure for water supply.

[0034] Furthermore, the pressurization unit includes a regional pressurization module, a floor pressurization module and a control module. The regional pressurization module is used to pressurize each floor in the floor unit, and the floor pressurization module is used for pressurization in each floor. The regional pressurization module is in a working state, and the floor pressurization module is in a standby state. The control module receives the pressurization command sent by the central control unit and controls the regional pressurization module to perform pressurization operation. The control module receives three pressurization commands in ten minutes in succession. The control module controls the regional pressurization module and the floor pressurization module to perform pressurization operation at the same time and sends a fault command to the central control unit. The pressurization unit is provided with a regional pressurization module and a floor pressurization module to perform pressurization operation together. The regional pressurization module is in a working state and pressurizes the three floors of each zone. operation, so one pressurizing module pressurizes three floors at the same time to save resources. When the three floors are pressurized, if the pressure on a certain floor is insufficient and water cannot be supplied normally, the control module will receive pressurization commands multiple times, which means that the regional pressurization module cannot provide enough pressure at this time. Therefore, the floor pressurization module will pressurize the floor with insufficient water pressure, so that the current floor can meet the pressure requirements. Therefore, the floor pressurization module can ensure that residents can use water resources normally, and maintenance personnel can carry out maintenance at an appropriate time, and there will be no sudden water outage. In addition, it should be noted that each floor is equipped with a floor pressurization module, but it is in standby state but not pressurized when the regional pressurization module is in normal use, and plays a role of auxiliary pressurization.

[0035] Furthermore, the control module sends a fault instruction to the central control unit, and the central control unit receives the fault instruction and extracts the floor information of the control module that sends the fault instruction, wherein the floor information comes from the detection unit, and the floor information includes unpressurized water pressure data YQ, pressurized water pressure data YH and water flow rate data LS, and the central control unit sends the floor information to the fault unit. When the central control unit receives the fault instruction, it indicates that there is a problem with the pressurization structure in the pressurization unit at this time. Therefore, the central control unit needs to extract the floor information where the fault will occur, and the first thing to be determined is the floor number. At this time, maintenance personnel can rush to the corresponding floor for maintenance, and extracting the unpressurized water pressure data YQ, pressurized water pressure data YH and water flow rate data LS can enable maintenance personnel to first roughly understand the problem caused by the fault, so that they can carry corresponding tools when performing maintenance.

[0036] Furthermore, the fault unit includes a display module and a judgment module. The display module receives the floor information sent by the central control unit and displays it on its display screen. The judgment module receives the floor information sent by the central control unit and compares the unpressurized water pressure data YQ, the pressurized water pressure data YH and the water flow rate data LS with the threshold value. The threshold value includes the first water pressure DY, the second water pressure DE and the standard water flow rate SD, so as to judge the problem in the water pipe of the secondary water supply, and the fault unit sends a maintenance instruction to the maintenance unit. When the judgment module compares the threshold value, the first problem is: the unpressurized water pressure data YQ is less than the first water pressure DY, which means the water inlet pressure is too low, and the second problem is: the pressurized water pressure data YH When it is lower than the second water pressure DE, the pressurized water pressure is too low. The third problem is: when the water flow rate data LS is less than the standard water flow rate SD, the water flow is too slow, and the judgment unit sends the problem to the display unit and displays it on the display screen of the display unit. In the embodiment of the present application, a display module and a judgment module are provided in the fault unit. The display unit can display various information, and the data in the display module is generally viewed by the management personnel, and when the terminal device displays it, it is provided to the personnel performing on-site maintenance for viewing, and the data in the display module and the terminal device can be used mutually, and the pressurized water pressure data YQ, the pressurized water pressure data YH and the water flow rate data LS are judged, so as to determine the location where the problem occurs.

[0037] Furthermore, the floor unit includes a statistical module and a partitioning module. The statistical module counts the number of floors in the building and sends the statistical results to the partitioning module. The partitioning module partitions the floors seven and above, and every three floors are divided into one zone. The first zone is 7-9 floors, the second zone is 10-12 floors, the third zone is 13-15 zones, and so on. When the number of floors left at the top of the floor is one, it is combined with the next floor into one zone. When the number of floors left at the top of the floor is two, these two floors are a separate zone. The present application first uses the statistical module in the floor unit, at which time the overall number of floors will be collected, and the partitioning module will partition it. At this time, the high-rise floors that require secondary water supply will be partitioned, thereby reducing the problem of incoordination in various aspects when each floor needs to be pressurized separately in the traditional way, and the pressure required between two adjacent floors is not much different, so when they are pressurized separately, resources are wasted.

The artificial intelligence-based secondary water supply pressure early warning and control system according to claim 6 is characterized in that: When the judgment module performs threshold comparison, the first problem is: when the unpressurized water pressure data YQ is less than the first water pressure DY, the inlet water pressure is too low; the second problem is: when the pressurized water pressure data YH is lower than the second water pressure DE, the pressurized water pressure is too low; the third problem is: when the water flow rate data LS is less than the standard water flow rate SD, the water flow is too slow, and the judgment unit sends the problem to the display unit and displays it on the display screen of the display unit.

8. The artificial intelligence-based secondary water supply pressure early warning and control system according to claim 1, characterized in that: The floor unit includes a statistical module and a partitioning module. The statistical module counts the number of floors in the building and sends the statistical results to the partitioning module. The partitioning module partitions the floors with seven floors or more, and divides every three floors into one zone. The first zone is 7-9 floors, the second zone is 10-12 floors, the third zone is 13-15 zones, and so on. When there is only one floor left at the top of the floor, it is combined with the next floor into one zone. When there are two floors left at the top of the floor, these two floors are a separate zone.

9. A secondary water supply pressure early warning and control method based on artificial intelligence, using a secondary water supply pressure early warning and control system based on artificial intelligence as claimed in any one of claims 1 to 8, characterized in that: The following steps are involved: Step S1, the detection unit detects the information in the secondary water supply pipe and sends it to the analysis unit, the analysis unit receives the data of the detection unit and forms a determination value U; Step S2: the early warning unit receives the determination value U and compares it with the threshold value, and then sends an instruction to the central control unit. The central control unit receives the instruction and instructs the maintenance unit to perform maintenance work; Step S3, the central control unit controls the pressurizing unit to perform pressurizing work on the secondary water supply. When the pressure is insufficient, the fault unit receives the information sent by the central control unit, makes a judgment, and then sends a command to the maintenance unit; Step S4: The maintenance unit receives instructions from the central control unit and the faulty unit and performs maintenance work.
