Description

Technical Field

[0001] This application belongs to the field of concrete construction technology, specifically relating to a control method, device, equipment, and medium for a concrete surface sprayer. Background Technology

[0002] Currently, in various large-volume concrete construction processes, the concrete pouring surface refers to the upper surface of each pouring section when large-volume concrete structures are poured in layers and blocks according to construction specifications. Spraying the pouring surface is a key process for controlling concrete temperature and preventing cracking.

[0003] In existing technologies, the determination of whether a sprayer is malfunctioning is usually based on a single data point, which is insufficient in terms of accuracy. Furthermore, when a sprayer malfunctions, due to the large volume of the concrete structure, the malfunctioning sprayer is often far from maintenance personnel, making timely restoration difficult. Consequently, the spraying effect on the concrete surface covered by the malfunctioning sprayer will be affected, thus impacting the curing quality of the concrete surface. Summary of the Invention

[0004] The purpose of this application is to provide a control method, device, equipment, and medium for a concrete surface sprayer, which is achieved as follows: In a first aspect, embodiments of this application provide a method for controlling a concrete slab surface sprayer, applied to a sprayer control system. The sprayer control system includes a plurality of concrete slab surface sprayers arranged sequentially, with adjacent concrete slab surfaces corresponding to adjacent sprayers. The method includes: Obtain the water supply pressure data and operating current data of each concrete sprayer. Determine whether the corresponding concrete surface sprayer is in a fault state based on the water supply pressure data and the operating current data; If any of the concrete surface sprayers is in a faulty state, the fault level of the faulty concrete surface sprayer shall be determined based on the water supply pressure data and the operating current data. According to the fault level, the concrete slab sprayer adjacent to the faulty concrete slab sprayer is controlled to spray the concrete slab corresponding to the faulty concrete slab sprayer.

[0005] Optionally, the sprayer control system further includes a water pressure detection component installed in the water inlet pipe of each of the concrete slab sprayers, and a current detection component installed in each of the concrete slab sprayers. The steps for obtaining the water supply pressure data and operating current data of each concrete surface sprayer include: The water pressure data of each concrete slab sprayer is collected by the water pressure detection component; The current detection component collects the operating current data of each concrete surface sprayer.

[0006] Optionally, the water supply pressure data includes water pressure value and water pressure fluctuation value, and the operating current data includes current value; The step of determining whether the corresponding concrete surface sprayer is in a fault state based on the water supply pressure data and the operating current data includes: Obtain the start / stop status of the concrete surface sprayer; If the water pressure is zero and the water pressure fluctuation is zero when the concrete surface sprayer is in the start-up state, then the concrete surface sprayer is determined to be in a fault state. If the water pressure is less than a preset water pressure reference value, the water pressure fluctuation value is greater than zero, and the current value is greater than a preset current reference value when the concrete surface sprayer is in the start-up state, then the concrete surface sprayer is determined to be in a fault state.

[0007] Optionally, if any of the concrete surface sprayers is in a faulty state, the step of determining the fault level of the faulty concrete surface sprayer based on the water supply pressure data and the operating current data includes: If the water pressure value is zero and the water pressure fluctuation value is zero, then the fault type is determined to be a water outage fault. If the water pressure value is less than the water pressure reference value, the water pressure fluctuation value is greater than zero, and the current value is greater than the current reference value, then the fault type is determined to be a filter blockage fault. The duration of the water outage or the duration of the filter blockage is taken as the fault duration. The fault level is determined based on the fault type and the fault duration.

[0008] Optionally, the step of determining the fault level based on the fault type and the fault duration includes: If the fault type is a water outage fault, and the fault duration is less than or equal to a preset first water outage duration, then the fault level is determined to be a short-term water outage. If the fault type is a water outage fault, and the fault duration is greater than a preset second water outage duration, then the fault level is determined to be a continuous water outage; wherein, the second water outage duration is greater than the first water outage duration.

[0009] Optionally, the step of determining the fault level based on the fault type and the fault duration further includes: In the case where the fault type is filter blockage, calculate the water pressure deviation between the water pressure value and the water pressure reference value, and the current deviation between the current value and the current reference value; If the water pressure deviation is within a preset first deviation range, the current deviation is within the first deviation range, and the fault duration is less than or equal to a preset first blockage duration, then the fault level is determined to be a mild blockage; wherein, the first deviation range is greater than or equal to a first deviation threshold and less than a second deviation threshold; If the water pressure deviation is within a preset second deviation range, the current deviation is within the second deviation range, and the fault duration is less than or equal to the first blockage duration, then the fault level is determined to be severe blockage; wherein, the second deviation range is greater than or equal to the second deviation threshold. If the fault level is mild congestion and the fault duration is greater than a preset second congestion duration, then the fault level is determined to be continuous congestion; wherein the second congestion duration is greater than the first congestion duration.

[0010] Optionally, the step of controlling the concrete surface sprayer adjacent to the faulty concrete surface sprayer to spray the concrete surface corresponding to the faulty concrete surface sprayer according to the fault level includes: When the fault level is short-term water outage or slight blockage, control at least one concrete slab sprayer adjacent to the faulty concrete slab sprayer to spray the concrete slab corresponding to the faulty concrete slab sprayer. When the fault level is continuous water outage, severe blockage or continuous blockage, control at least two concrete slab sprayers adjacent to the faulty concrete slab sprayer to spray the concrete slab surface corresponding to the faulty concrete slab sprayer. The process of controlling the adjacent concrete slab sprayers to spray the concrete slab surface corresponding to the faulty concrete slab sprayer includes: Control the adjacent concrete slab sprayers to expand the spray coverage area and / or adjust the spray angle so that the concrete slab surface corresponding to the adjacent concrete slab sprayers covers the concrete slab surface corresponding to the faulty concrete slab sprayer.

[0011] Optionally, the sprayer control system further includes a display component and a data transmission component, and the sprayer control system communicates with a remote monitoring platform through the data transmission component; The method further includes: The display component shows the fault level of each concrete slab sprayer. If the fault level is short-term water outage, then water outage warning information will be displayed on the display component; If the fault level is mild congestion, a cleaning warning message will be displayed on the display component; If the fault level is continuous water outage, severe blockage, or continuous blockage, then an emergency alarm message is triggered on the remote monitoring platform. If the fault level is severe blockage, the audible and visual alarm device near the faulty concrete sprayer will also be triggered to issue an audible and visual alarm.

[0012] Secondly, embodiments of this application provide a control device for a concrete slab surface sprayer, applied to a sprayer control system. The sprayer control system includes a plurality of concrete slab surface sprayers arranged sequentially, with adjacent concrete slab surfaces corresponding to adjacent sprayers. The device includes: The data acquisition module is used to acquire the water supply pressure data and operating current data of each concrete sprayer. The fault diagnosis module is used to determine whether the corresponding concrete surface sprayer is in a fault state based on the water supply pressure data and the operating current data. The fault level determination module is used to determine the fault level of any of the concrete surface sprayers based on the water supply pressure data and the operating current data if any of the concrete surface sprayers is in a fault state. The supplementary spray module is used to control the concrete surface sprayer adjacent to the faulty concrete surface sprayer to spray the concrete surface corresponding to the faulty concrete surface sprayer according to the fault level.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the various embodiments of this application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this application to enable readers to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and various changes and updates based on the following embodiments. The division of the various embodiments below is for the convenience of description and should not constitute any limitation on the specific implementation of this application. The various embodiments can be combined with and referenced by each other without contradiction.

[0019] Currently, in concrete formwork spray control technologies, microclimate control systems can only adjust the spraying pattern based on climate parameters such as temperature, humidity, and wind speed, without addressing the fault warning function of the spraying equipment itself. Adaptive microclimate control methods for concrete formwork focus on optimizing spray volume calculation algorithms, lacking designs for diagnosing equipment faults. Concrete environment control methods and devices can only trigger alarms when environmental parameters exceed thresholds, failing to distinguish fault types. For example, both water outages and filter blockages manifest as abnormal water supply pressure, but existing technologies cannot differentiate between the two.

[0020] Because existing technology can only monitor abnormalities such as reduced water supply pressure, it cannot determine whether the water outage is caused by no water supply in the water supply pipeline or by filter blockage caused by dirt accumulation on the filter screen, which can easily lead to misdiagnosis and repair.

[0021] Furthermore, current technologies typically rely on a single data point to determine if a sprayer is malfunctioning, resulting in insufficient accuracy in fault diagnosis. Moreover, when a sprayer malfunctions, the large volume of concrete structures and the considerable distance between the malfunctioning sprayer and maintenance personnel make timely restoration difficult. Consequently, the spraying effect on the concrete surface covered by the malfunctioning sprayer will be affected, thus impacting the curing quality of the concrete surface.

[0022] Therefore, this application provides a control method, device, equipment, and medium for a concrete surface sprayer, which can determine whether the sprayer is faulty by using water supply pressure data and operating current data, thus improving the accuracy of fault diagnosis. Furthermore, it can promptly perform supplementary spraying, ensuring that the spraying effect on the concrete surface under the responsibility of the faulty sprayer is not affected, thereby guaranteeing the curing quality of the concrete surface.

[0023] This application belongs to the field of concrete construction technology for water conservancy and hydropower projects. Specifically, it can be used for fault early warning, remote monitoring and linkage control of concrete placement spray equipment. It can be adapted to intelligent temperature control construction scenarios for large-volume concrete placement surfaces, including hydropower station dams or bridges, piers, etc.

[0024] Reference Figure 1 The diagram illustrates a flowchart of the steps of a concrete slab surface sprayer control method according to an embodiment of this application.

[0025] This is applied to a sprayer control system, which includes a plurality of concrete slab sprayers arranged in sequence, with adjacent concrete slabs corresponding to adjacent sprayers.

[0026] This is applied to a sprayer control system, which includes a plurality of concrete slab sprayers arranged in sequence, with adjacent concrete slabs corresponding to adjacent sprayers.

[0027] In this embodiment of the application, the concrete surface sprayer control method can be applied to a sprayer control system. The sprayer control system consists of multiple concrete surface sprayers arranged in a certain order, and the concrete surface areas sprayed by the adjacent sprayers are also adjacent to each other, forming a continuous and complete curing coverage network.

[0028] Among them, the sprayer control system can refer to the overall system architecture used for centralized or distributed control, status monitoring, data interaction, and decision execution of multiple sprayers.

[0029] A concrete surface sprayer can refer to a device specifically installed around or at the edge of a concrete surface to spray water mist onto the concrete surface for temperature control and moisture retention.

[0030] The concrete surface can refer to the upper surface of each pouring unit, i.e., the pouring chamber, during the construction of large-volume concrete in layers and blocks. The concrete surface is the direct target of spray curing operations.

[0031] The method may specifically include the following steps: Step 101: Obtain the water supply pressure data and operating current data of each concrete slab sprayer; In this embodiment of the application, the sprayer control system collects water pressure data and operating current data of each concrete slab sprayer during operation.

[0032] Water supply pressure data can indicate the water pressure status in the water inlet pipe of the sprayer. Water supply pressure data can include water pressure value and water pressure fluctuation value.

[0033] Operating current data can indicate the operating current status of the sprayer motor, and the operating current data can include current values.

[0034] Step 102: Determine whether the corresponding concrete surface sprayer is in a fault state based on the water supply pressure data and the operating current data; In this embodiment, the sprayer control system can determine the fault status of each concrete slab sprayer based on water supply pressure data and operating current data.

[0035] In practical implementation, the water pressure value and water pressure fluctuation value in the water supply pressure data can reflect whether the water pressure in the sprayer's inlet pipe is zero, stable, or fluctuating. The current value in the operating current data can reflect whether the operating current of the sprayer motor has increased abnormally. By comprehensively analyzing the water pressure value, water pressure fluctuation value, and current value, the sprayer control system can determine whether the sprayer is in a faulty state.

[0036] Step 103: If any of the concrete surface sprayers is in a fault state, the fault level of the faulty concrete surface sprayer is determined based on the water supply pressure data and the operating current data. In this embodiment of the application, when the sprayer control system determines that a certain concrete slab sprayer is faulty, it further determines the fault level of the faulty concrete slab sprayer based on the water supply pressure data and operating current data of the faulty concrete slab sprayer.

[0037] The fault level reflects the severity and urgency of the fault. Different fault levels correspond to different fault handling methods.

[0038] Step 104: Based on the fault level, control the concrete slab sprayer adjacent to the faulty concrete slab sprayer to spray the concrete slab surface corresponding to the faulty concrete slab sprayer.

[0039] In this embodiment of the application, the sprayer control system selects one or more normally operating concrete slab sprayers adjacent to the faulty concrete slab sprayer according to the determined fault level, and controls these adjacent concrete slab sprayers to spray and cover the concrete slab area originally covered by the faulty sprayer.

[0040] By controlling adjacent sprayers to provide supplementary spraying, it can be ensured that the concrete surface area corresponding to the malfunctioning sprayer can still receive continuous spraying and curing, thus avoiding interruption of curing due to the failure of a single device.

[0041] In this embodiment, the water pressure and operating current data of each concrete surface sprayer are acquired. Based on these data, it is determined whether the corresponding sprayer is in a faulty state. This method improves the accuracy of fault diagnosis by using water pressure and operating current data to determine if a sprayer is faulty. If any concrete surface sprayer is faulty, its fault level is determined based on the water pressure and operating current data. Based on the fault level, the adjacent sprayer is controlled to spray the corresponding concrete surface. This method allows for timely replacement spraying, ensuring that the spraying effect on the faulty sprayer's surface is not affected, thus guaranteeing the curing quality of the concrete surface.

[0042] Optionally, the sprayer control system also includes a water pressure detection component installed in the water inlet pipe of each concrete surface sprayer, and a current detection component installed in each concrete surface sprayer.

[0043] In this embodiment, the sprayer control system may also be equipped with a water pressure detection component and a current detection component. The water pressure detection component is installed on the water inlet pipe of each concrete surface sprayer. The current detection component is installed on each concrete surface sprayer.

[0044] In a practical implementation, the water pressure detection component can be a sealed water pressure detection switch installed at the front end of the water inlet pipe of each concrete sprayer, 15 centimeters away from the water inlet. The water pressure detection component can sense and collect the water pressure signal in the water inlet pipe in real time.

[0045] The current detection component can be a current transformer to collect the operating current of each concrete sprayer. The current detection component can sense and collect the operating current signal of the sprayer motor in real time.

[0046] The steps for obtaining water supply pressure data and operating current data for each concrete sprayer include: S11, collects water pressure data of each concrete sprayer surface through water pressure detection components; S12 collects the operating current data of each concrete sprayer through the current detection component.

[0047] In this embodiment of the application, the sprayer control system can collect the water pressure data of each sprayer by means of a water pressure detection component installed on the water inlet pipe of each concrete slab sprayer.

[0048] In this embodiment of the application, the sprayer control system can collect the operating current data of each sprayer by means of a current detection component installed on each concrete slab sprayer.

[0049] In practical implementation, no modification is required to the mechanical structure of the original concrete surface sprayer. Only the addition of a water pressure detection component to the water inlet pipe and a current detection component to the sprayer, along with the reuse of the original central controller and data transmission component, is needed to achieve the technical solution of this application.

[0050] This application achieves accurate acquisition of water pressure and operating current data for each concrete sprayer by independently configuring a water pressure detection component installed in the water inlet pipe and a current detection component installed on the sprayer. The water pressure detection component uses a sealed water pressure detection switch to acquire water pressure signals in real time, and the current detection component uses a current transformer to acquire operating current signals in real time. This provides a reliable and accurate data foundation for subsequent fault diagnosis based on two parameters, solving the problem of single data sources in existing technologies.

[0051] Optionally, the water supply pressure data includes the water pressure value and the water pressure fluctuation value, and the operating current data includes the current value.

[0052] In this embodiment, the water supply pressure data may specifically include the water pressure value and the water pressure fluctuation value. The operating current data may specifically include the current value.

[0053] The water pressure value indicates the magnitude of the water pressure in the sprayer's inlet pipe. The water pressure fluctuation value indicates the degree of fluctuation or instability of the water pressure in the sprayer's inlet pipe. The current value indicates the magnitude of the operating current of the sprayer's motor.

[0054] The steps for determining whether a concrete spraying machine is malfunctioning based on water supply pressure data and operating current data include: S21, obtain the start / stop status of the concrete surface sprayer; S22, If the water pressure is zero and the water pressure fluctuation is zero when the concrete surface sprayer is in the start-up state, the concrete surface sprayer is determined to be in a fault state. S23, when the concrete surface sprayer is in the start-up state, if the water pressure value is less than the preset water pressure reference value, the water pressure fluctuation value is greater than zero, and the current value is greater than the preset current reference value, then the concrete surface sprayer is determined to be in a fault state.

[0055] In this embodiment, the sprayer control system first obtains whether each concrete surface sprayer is currently in a started or stopped state. The start / stop status is used to determine whether the sprayer is running; fault determination of water supply pressure and operating current data is only meaningful when the sprayer is running.

[0056] In practice, limit switches can be used to collect the start and stop signals of each concrete slab sprayer. The limit switches can be integrated into the control cabinet of each concrete slab sprayer.

[0057] In this embodiment, when the concrete surface sprayer is in the start-up state, the sprayer control system checks the water pressure value and water pressure fluctuation value in the water supply pressure data. If the water pressure value is equal to zero and the water pressure fluctuation value is also equal to zero, it means that there is neither water pressure nor any pressure fluctuation in the water inlet pipe, and the sprayer control system can determine that the sprayer is in a fault state.

[0058] In this embodiment, when the concrete surface sprayer is in the start-up state, the sprayer control system checks the water pressure value and water pressure fluctuation value in the water supply pressure data, as well as the current value in the operating current data. If the water pressure value is lower than the preset water pressure reference value, while the water pressure fluctuation value is greater than zero, and the current value is higher than the preset current reference value, the sprayer control system determines that the sprayer is in a fault state.

[0059] The water pressure reference value represents the standard water pressure that the concrete surface sprayer should reach in the inlet pipe during normal operation. The current reference value represents the standard operating current that the motor of the concrete surface sprayer should reach during normal operation. In specific implementations, the water pressure reference value and the current reference value can be set by those skilled in the art according to the actual situation.

[0060] This application obtains the start / stop status of the sprayer and performs fault determination only when the sprayer is running, avoiding invalid false alarms when the sprayer is stopped. Simultaneously, this application introduces three dimensions of parameters—water pressure, water pressure fluctuation, and current—for comprehensive judgment. A water outage fault is identified when the water pressure is zero and the fluctuation is zero; a blockage fault is identified when the water pressure is below a reference value, the fluctuation is greater than zero, and the current is higher than a reference value. This solves the problem of existing technologies being unable to distinguish between water outage faults and filter blockage faults, achieving accurate fault type identification and avoiding misdiagnosis due to misjudgment based on a single parameter.

[0061] Optionally, if any concrete surface sprayer is in a faulty state, the step of determining the fault level of the faulty concrete surface sprayer based on water supply pressure data and operating current data includes: S31, if the water pressure value is zero and the water pressure fluctuation value is zero, then the fault type is determined to be a water outage fault; S32, if the water pressure value is less than the water pressure reference value, the water pressure fluctuation value is greater than zero, and the current value is greater than the current reference value, then the fault type is determined to be filter blockage fault; S33, the duration of the water outage or the duration of the filter blockage is taken as the fault duration; S34. Determine the fault level based on the fault type and fault duration.

[0062] In this embodiment, the sprayer control system can check the water pressure data of the faulty sprayer. If the water pressure value is zero and the water pressure fluctuation value is also zero, the sprayer control system can determine the type of fault as a water outage fault.

[0063] A water outage fault indicates a type of malfunction where the sprayer cannot spray water mist normally because there is no water supply in the water supply pipeline.

[0064] In this embodiment, the sprayer control system can check the water pressure data and operating current data of the faulty sprayer. If the water pressure value is lower than the water pressure reference value, while the water pressure fluctuation value is greater than zero, and the current value is higher than the current reference value, the sprayer control system can determine the type of fault as a filter blockage fault.

[0065] A clogged filter can indicate a problem caused by dirt buildup on the filter screen, which obstructs water supply, causes a drop in water pressure with fluctuations, and increases the motor load, leading to higher operating current.

[0066] In this embodiment, the sprayer control system can start timing from the first occurrence of a fault and record the duration of the fault. If the fault type is a water outage fault, the duration of the water outage fault is recorded; if the fault type is a filter blockage fault, the duration of the filter blockage fault is recorded. The recorded duration is the fault duration.

[0067] Among them, fault duration can represent the length of time that has elapsed from the beginning of the fault state to the current moment.

[0068] In this embodiment, the sprayer control system can comprehensively determine the fault level by combining two factors: fault type and fault duration. Different fault types correspond to different duration thresholds. By comparing the actual fault duration with the corresponding fault type's duration threshold, different fault levels can be identified.

[0069] This application accurately distinguishes between water outages and filter blockages by using water pressure values ​​and water pressure fluctuation values, and introduces the duration of the fault as a basis for severity classification, thus overcoming the shortcomings of existing technologies that cannot identify specific fault types and rely solely on a single parameter for fault determination. Furthermore, this application combines fault type and fault duration for comprehensive evaluation, achieving graded and quantifiable assessment of fault severity, and providing a precise decision-making basis for subsequent graded and coordinated interventions.

[0070] Optionally, the step of determining the fault level based on the fault type and fault duration includes: S41, In the case of a water outage fault, if the fault duration is less than or equal to the preset first water outage duration, the fault level is determined to be a short-term water outage. S42, if the fault type is water outage fault, and the fault duration is greater than the preset second water outage duration, then the fault level is determined to be continuous water outage; wherein, the second water outage duration is greater than the first water outage duration.

[0071] In this embodiment, when the fault type is a water outage fault, the sprayer control system compares the actual recorded fault duration with a preset first water outage duration. If the fault duration is less than or equal to the first water outage duration, the sprayer control system determines the level of the water outage fault as a short-term water outage.

[0072] The first water outage duration can refer to a pre-set threshold for classifying short-term water outages; anything exceeding this threshold is no longer considered a short-term outage. In practice, the first water outage duration can be set according to actual conditions, for example, to 5 seconds.

[0073] A short-term water outage can be described as a water outage that is short in duration and is considered a temporary water outage.

[0074] In this embodiment, when the fault type is a water outage fault, the sprayer control system compares the actual recorded fault duration with a preset second water outage duration. The second water outage duration is longer than the first water outage duration. If the fault duration is longer than the second water outage duration, the sprayer control system determines the level of the water outage fault as a continuous water outage.

[0075] The second water outage duration can refer to a pre-set threshold for classifying continuous water outages. If the duration exceeds the first water outage duration, it is considered a continuous water outage. In practice, the second water outage duration can be set according to actual conditions, for example, 30 seconds.

[0076] A persistent water outage indicates a prolonged water outage, classifying it as a continuous water outage fault that requires an upgraded handling strategy.

[0077] This application categorizes water outages into two levels: short-term and continuous, by comparing the duration of the outage with preset first and second outage durations. This solves the problem of existing technologies being unable to classify the severity of faults, achieving a refined classification of water outage faults and providing an accurate basis for subsequent differentiated emergency response strategies based on fault severity.

[0078] Optionally, the step of determining the fault level based on the fault type and fault duration further includes: S51, In the case of a filter blockage fault, calculate the water pressure deviation between the water pressure value and the water pressure reference value, and the current deviation between the current value and the current reference value. S52, if the water pressure deviation is within the preset first deviation range, the current deviation is within the first deviation range, and the fault duration is less than or equal to the preset first blockage duration, then the fault level is determined to be a mild blockage; wherein, the first deviation range is greater than or equal to the first deviation threshold and less than the second deviation threshold. S53, if the water pressure deviation is within the preset second deviation range, the current deviation is within the second deviation range, and the fault duration is less than or equal to the first blockage duration, then the fault level is determined to be severe blockage; wherein, the second deviation range is greater than or equal to the second deviation threshold. S54, if the fault level is mild congestion and the fault duration is greater than the preset second congestion duration, then the fault level is determined to be continuous congestion; wherein, the second congestion duration is greater than the first congestion duration.

[0079] In this embodiment of the application, when the fault type is filter blockage, the sprayer control system calculates the degree of deviation of the water pressure value from the water pressure reference value to obtain the water pressure deviation amount; at the same time, it calculates the degree of deviation of the current value from the current reference value to obtain the current deviation amount.

[0080] Among them, the water pressure deviation indicates the degree of deviation of the current water pressure value from the water pressure reference value. Since the water pressure value is less than the water pressure reference value, it is determined to be a filter blockage fault. Therefore, the water pressure deviation is used to indicate the magnitude of the water pressure drop.

[0081] Current deviation indicates the degree of deviation of the current value from the current reference value. Since a filter blockage fault is only determined when the current value is greater than the current reference value, current deviation is used to indicate the magnitude of the current increase.

[0082] In this embodiment, the sprayer control system can check the range of water pressure deviation and current deviation, and also check the fault duration. If the water pressure deviation falls within a first deviation range, the current deviation also falls within a first deviation range, and the fault duration is less than or equal to a first blockage duration, the sprayer control system can determine the level of the filter blockage fault as mild blockage.

[0083] The first deviation interval can be a numerical range that is greater than or equal to the first deviation threshold and less than the second deviation threshold.

[0084] The first deviation threshold can be the lower limit of deviation corresponding to mild blockage, which can be set according to the actual situation, for example, 10%.

[0085] The second deviation threshold can be the upper limit of the deviation amount corresponding to mild congestion, and it is also the dividing value between mild and severe congestion. It can be set according to the actual situation, for example, 20%.

[0086] The first congestion duration can be a pre-set threshold used to distinguish between light and heavy congestion. In practice, the first congestion duration can be set according to the actual situation, for example, to 5 seconds.

[0087] Mild clogging indicates a clogging level where the filter is only slightly clogged, the deviation is low, and the duration is short.

[0088] In this embodiment, the sprayer control system can check the range of water pressure deviation and current deviation, and also check the fault duration. If the water pressure deviation falls within the second deviation range, the current deviation also falls within the second deviation range, and the fault duration is less than or equal to the first clogging duration, the sprayer control system can determine the level of the filter clogging fault as severe clogging.

[0089] The second deviation interval can be greater than or equal to the numerical range of the second deviation threshold.

[0090] Severe clogging indicates a serious degree of filter blockage, with deviations from the standard range and a short duration, requiring immediate attention.

[0091] In this embodiment, the sprayer control system can check the fault level and fault duration. If the current fault level is mild clogging and the fault duration is greater than the second clogging duration, the sprayer control system can escalate the fault level to persistent clogging.

[0092] The second congestion duration can be a pre-set threshold for determining whether a mild congestion has escalated into a persistent congestion, and it must be longer than the first congestion duration. In practice, the second congestion duration can be set according to the actual situation, for example, to 30 seconds.

[0093] Persistent congestion can be an escalation of a congestion fault level that occurs when a mild congestion persists for too long without being addressed.

[0094] This application calculates water pressure and current deviations, classifies the deviations using a first and second deviation range, and further subdivides filter clogging faults into three levels: mild clogging, severe clogging, and persistent clogging by comparing the fault duration with the durations of the first and second blockages. This solves the problem of existing technologies being unable to classify the severity of clogging faults, achieving a refined classification of filter clogging faults and providing an accurate basis for subsequent differentiated linkage and compensation strategies based on fault level.

[0095] Optionally, the step of controlling the concrete surface sprayer adjacent to the faulty concrete surface sprayer to spray the concrete surface corresponding to the faulty concrete surface sprayer according to the fault level includes: S61, when the fault level is short-term water outage or slight blockage, control at least one concrete slab sprayer adjacent to the faulty concrete slab sprayer to spray the concrete slab corresponding to the faulty concrete slab sprayer. S61, when the fault level is continuous water outage, severe blockage or continuous blockage, control at least two concrete slab sprayers adjacent to the faulty concrete slab sprayer to spray the concrete slab corresponding to the faulty concrete slab sprayer.

[0096] In this embodiment, the sprayer control system can select a corresponding linkage compensation strategy based on the fault level. When the fault level is a short-term water outage or a minor blockage, the sprayer control system selects at least one normally operating concrete slab sprayer from the adjacent positions of the faulty sprayer and controls the adjacent sprayer to spray and cover the concrete slab originally covered by the faulty sprayer.

[0097] Adjacent concrete surface sprayers can refer to one or more sprayers that are directly adjacent to the faulty sprayer in the sprayer arrangement sequence, including the left-side adjacent sprayer and the right-side adjacent sprayer.

[0098] The concrete pouring surface refers to the upper surface of each pouring unit, i.e., the pouring chamber, during the layered and segmented pouring of large-volume concrete. It is the direct target of spray curing operations.

[0099] In the embodiments of this application, when the fault level is continuous water outage, severe blockage or continuous blockage, these fault levels are relatively serious. The sprayer control system selects at least two normally operating concrete surface sprayers from the adjacent positions of the faulty sprayer and controls these adjacent sprayers to spray and cover the concrete surface area originally handled by the faulty sprayer.

[0100] This includes controlling adjacent concrete slab sprayers to spray the concrete slab surface corresponding to the malfunctioning concrete slab sprayer, including: S63, control the adjacent concrete slab sprayer to expand the spray coverage area and / or adjust the spray angle so that the concrete slab corresponding to the adjacent concrete slab sprayer covers the concrete slab corresponding to the faulty concrete slab sprayer.

[0101] In this embodiment of the application, when the sprayer control system controls the selected adjacent sprayers to perform supplementary spraying, it can expand the spray coverage of the adjacent sprayers, adjust the spray angle of the adjacent sprayers, or simultaneously expand the spray coverage and adjust the spray angle, so that the concrete surface area originally covered by the adjacent sprayers can be extended and covered to the concrete surface area originally covered by the faulty sprayer, thereby achieving blind-spot-free spraying maintenance of the entire faulty area.

[0102] The spray coverage area can refer to the area of ​​the concrete surface that can be covered by the water mist sprayed by a single sprayer.

[0103] The spray angle refers to the fan-shaped angle of water mist diffusion when a sprayer sprays water mist, and is used to determine the direction and range of the spray coverage area.

[0104] In practice, concrete surface sprayers can be arranged at equal intervals along the concrete surface, such as the transverse joints of a dam section, with the spacing between adjacent concrete surface sprayers designed to achieve full coverage of the concrete surface.

[0105] A single concrete surface sprayer can cover the concrete surface area of ​​the corresponding dam section with a 90-degree fan-shaped spray angle. The coverage areas of adjacent concrete surface sprayers are seamlessly connected, forming a complete concrete surface curing network.

[0106] When a concrete sprayer malfunctions and stops, the adjacent sprayer to its left adjusts its spray angle from 90 degrees to 60 degrees, shifting it 30 degrees towards the faulty area. The adjacent sprayer to its right adjusts its spray angle from 90 degrees to 120 degrees, also shifting it 30 degrees towards the faulty area. The adjusted fan-shaped spray areas from the two adjacent sprayers completely overlap with the original coverage area of ​​the faulty sprayer, achieving 100% coverage with no blind spots.

[0107] The above-mentioned spray angle settings are calculated based on the width of the dam section, the installation height of the concrete surface sprayer, and the diffusion range of the mist particles. Deflection angles of 60 degrees and 120 degrees ensure effective coverage while avoiding excessive spraying that could lead to water accumulation in the concrete surface. Those skilled in the art can also set their own deflection angles to ensure effective coverage while avoiding excessive spraying that could lead to water accumulation in the concrete surface, based on actual conditions.

[0108] This application addresses the issue of interrupted spraying in the area corresponding to the faulty sprayer by selecting at least one or two adjacent sprayers to compensate for the fault based on the fault level. It also controls the adjacent sprayers to expand their spray coverage and adjust their spray angles, ensuring that the spray area of ​​the adjacent sprayers completely covers the original spray area of ​​the faulty sprayer. This solves the problem of interrupted spraying in the area corresponding to the faulty sprayer, achieving precise and blind-spot-free compensation coverage of the faulty area and ensuring uninterrupted curing of the concrete surface.

[0109] Optionally, the sprayer control system also includes a display component and a data transmission component, through which the sprayer control system communicates with a remote monitoring platform.

[0110] In this embodiment, the sprayer control system may also be equipped with a display component and a data transmission component. The sprayer control system utilizes the data transmission component to establish a communication connection with a remote monitoring platform.

[0111] Display components can refer to visual devices used to show on-site workers the operating status and fault information of sprayers.

[0112] The data transmission component refers to the communication module used to enable data interaction between the sprayer control system and the remote monitoring platform. In specific implementations, the data transmission component is selected as an industrial-grade data transmission component that supports 4G or 5G communication. The data transmission component is electrically connected to the output of the water pressure detection component to transmit water pressure signals to the remote monitoring platform and realize bidirectional data interaction with the central controller.

[0113] A remote monitoring platform refers to a monitoring system deployed in the cloud, used to receive, store, and display data and fault information uploaded by each sprayer. In specific implementations, the remote monitoring platform can adopt a cloud platform architecture, communicating with data transmission components via 4G or 5G networks to receive and store water pressure data, fault information, and alarm records.

[0114] In practice, the remote monitoring platform is equipped with indicator lights for the sprayer's operating status. A green indicator light corresponds to a sprayer with both water and electricity, a red indicator light corresponds to a sprayer with electricity but no water, and a gray indicator light corresponds to a sprayer without electricity. The construction management unit, construction unit, supervision unit, and design unit can all access the remote monitoring platform at any time to check the sprayer's operating status.

[0115] In the specific implementation, refer to Figure 2 The diagram shows a display interface of a remote monitoring platform provided in one embodiment of this application.

[0116] like Figure 2 As shown, the remote monitoring platform displays an overview of the sprayer's operation. This interface shows the construction section number where the sprayer is located, for example, the sprayer is in section 03-05 of line 20.

[0117] The remote monitoring platform can display monitoring data of the current construction environment, including external humidity, external wind speed, external temperature, and solar radiation. For example, the external humidity is 49.3%, the external wind speed is 0.5 meters per second, the external temperature is 32.5 degrees Celsius, and the solar radiation is 243.4 watts per square meter.

[0118] The remote monitoring platform can display the number and serial number of the sprayers in operation. For example, there are currently 3 sprayers in operation, numbered 1, 2, and 4.

[0119] The remote monitoring platform displays the operating status of each sprayer using status indicator lights. Sprayers with both water and electricity are displayed as green or gray dots, sprayers with electricity but no water are displayed as red or black dots, and sprayers without power are displayed as hollow circles. For example, sprayers 1 and 4 indicate that they are operating normally with both water and electricity, sprayer 2 indicates that it has power but no water, and the remaining sprayers indicate that they are not operating and have no power.

[0120] Construction management units, construction units, supervision units, and design units can all access the remote monitoring platform at any time to check the equipment operation status of each sprayer.

[0121] The method further includes the following steps: S71 displays the fault level of each concrete slab sprayer via a display component; S72, if the fault level is short-term water outage, then the water outage warning information will be displayed on the display component; S73, if the fault level is mild blockage, a cleaning warning message will be displayed on the display component; S74, if the fault level is continuous water outage, severe blockage or continuous blockage, an emergency alarm message will be triggered on the remote monitoring platform. S75, if the fault level is severe blockage, it will also trigger the audible and visual alarm device near the faulty concrete sprayer to issue an audible and visual alarm.

[0122] In this embodiment of the application, the sprayer control system can use a display component to visually present the fault level of each concrete slab sprayer to the on-site personnel.

[0123] In this embodiment of the application, when the fault level is short-term water outage, the sprayer control system displays warning information related to the water outage on the display component to remind on-site personnel to pay attention to the water outage situation.

[0124] Water outage warning information can refer to visual prompts used to indicate the occurrence of water outages.

[0125] In this embodiment, when the fault level is mild clogging, the sprayer control system displays cleaning-related warning information on the display component to remind on-site personnel to clean the filter during maintenance.

[0126] Cleanup alerts can refer to visual prompts that indicate when a filter needs to be cleaned.

[0127] In this embodiment, when the fault level is continuous water outage, severe blockage, or continuous blockage, these fault levels are relatively serious. The sprayer control system sends emergency alarm information to the remote monitoring platform through the data transmission component, triggering the remote monitoring platform to generate an emergency alarm. At the same time, it can send a shutdown reminder so that remote management personnel can be informed and handle the situation in a timely manner.

[0128] Emergency alarm information can refer to notification information used to trigger emergency alarms on a remote monitoring platform.

[0129] In this embodiment of the application, when the fault level is severe blockage, in addition to triggering the emergency alarm of the remote monitoring platform, the sprayer control system also triggers the audible and visual alarm device installed near the faulty sprayer. The device emits audible and visual alarm signals to facilitate on-site personnel to quickly locate the faulty equipment.

[0130] Audible and visual alarm devices refer to equipment installed near sprayers that can emit sound and light alarm signals to prompt on-site personnel to quickly locate faulty equipment. Audible and visual alarms can refer to alarm signals emitted simultaneously through both sound and light.

[0131] In the specific implementation, refer to Figure 3 The diagram shows a display interface schematic of a display component provided in an embodiment of this application.

[0132] like Figure 3 As shown, the main interface of the display component synchronously displays monitoring data from both the programmable logic controller side and the data transmission component side.

[0133] The programmable logic controller (PLC) displays the first analog-to-digital conversion detection value (AD detection 1), the second analog-to-digital conversion detection value (AD detection 2), the first digital-to-analog conversion output value (DA1 output), the second digital-to-analog conversion output value (DA2 output), the water pressure detection status, and the start / stop output status.

[0134] The first analog-to-digital conversion detection value is 5.0, representing the detection value input by the water pressure sensor; the second analog-to-digital conversion detection value is 3.0, representing the detection value input by the water pump operating current. The first digital-to-analog conversion output value is 9, representing the output value controlling the water pump speed; the second digital-to-analog conversion output value is 14, representing the output value controlling the spray angle.

[0135] In the implementation, the water pressure detection status can be displayed as a green icon, indicating that the water pressure is normal. The start / stop output status display has three channels: Y0, Y1, and Y2, which correspond to the start / stop control of the three sprayers, respectively. Red indicates that there is no manual operation locally.

[0136] The data transmission component displays the first analog-to-digital conversion detection value (AD detection 1), the second analog-to-digital conversion detection value (AD detection 2), the first digital-to-analog conversion output value (DA1 output), the second digital-to-analog conversion output value (DA2 output), the water pressure detection status, and the start / stop output status.

[0137] The first analog-to-digital conversion detection value is 5.0, the second analog-to-digital conversion detection value is 3.0, the first digital-to-analog conversion output value is 9, and the second digital-to-analog conversion output value is 14.

[0138] In the implementation, the water pressure detection status can be displayed as a green icon, indicating that the water pressure is normal. The start / stop output status display has three channels, Q1, Q2, and Q3, which correspond to the remote start / stop control of the three sprayers, respectively. Green indicates that the remote command is valid. Figure 3 This is the display interface when the water pressure is normal. Figure 3 In the test, the start / stop output status of Q1, Q2, and Q3 are all normal.

[0139] By displaying monitoring data from both the programmable logic controller (PLC) and data transmission components simultaneously, on-site personnel can monitor the real-time operating status of the sprayer and the remote communication control status.

[0140] In the specific implementation, refer to Figure 4 The diagram shows a schematic representation of the display interface of another display component provided in an embodiment of this application.

[0141] like Figure 4 As shown, the main interface of the display component synchronously displays monitoring data from both the programmable logic controller (PLC) side and the data transmission component side. Specific values ​​can be found in [reference needed]. Figure 3 The explanation, Figure 4 This is the display interface when the water pressure is insufficient. Figure 4 In the diagram, the start / stop output state of Q1 differs from that of Q2 and Q3. The start / stop output state of Q1 is abnormal. The start / stop output states of Q2 and Q3 are both normal.

[0142] This application displays fault levels using a display component and triggers differentiated early warning information based on different fault levels, including water outage warnings, cleaning warnings, remote emergency alarms, and proximity audible and visual alarms. It solves the problem that existing technologies cannot provide graded early warnings based on fault severity, realizing a multi-level, multi-mode early warning system from the field to remote locations. This facilitates rapid location of faulty equipment by on-site personnel while ensuring timely fault information for remote management personnel.

[0143] Optionally, this application, by adding a water pressure detection component and a current detection component, achieves accurate judgment of whether there is a true water outage in the water supply pipeline of the sprayer, solving the problem of existing technologies being unable to distinguish between water supply interruptions and false alarms caused by filter blockage. The specific technical solution is as follows: The sprayer control system of this application includes a water pressure detection component, a current detection component, a data transmission component, a central controller, a display component, a multi-machine status monitoring component, and a remote monitoring platform.

[0144] The water pressure detection component is a sealed water pressure detection switch, installed in the water inlet pipe of the concrete surface sprayer. The output of the water pressure detection component is electrically connected to the signal input of the data transmission component. The water pressure detection component is used to collect real-time water pressure signals from the water supply pipeline. The current detection component is used to collect the operating current signal of the concrete surface sprayer; the start / stop signal is obtained from the central controller. In the specific implementation, the output of the water pressure detection component of each concrete surface sprayer is electrically connected to the analog signal input of the corresponding data transmission component via a waterproof cable, and the wiring terminals are waterproof and sealed.

[0145] The output terminal of the current sensing component is electrically connected to the signal input terminal of the central controller. In a specific implementation, the current signal output terminal and the start / stop signal output terminal of the current sensing component are electrically connected to the analog input terminal and the digital input terminal of the central controller, respectively.

[0146] The Data Transfer Unit (DTU) receives water pressure signals from the water pressure detection unit. The DTU establishes a wireless connection with the remote monitoring platform and a bidirectional communication connection with the display unit. In practice, the DTU's interface connects to the central controller's communication interface for data exchange. The DTU establishes a wireless communication link with the remote monitoring platform via a 4G or 5G network.

[0147] The central controller is used to integrate and process water pressure signals, feedback information from data transmission components, and equipment operating parameters. The central controller establishes a two-way communication connection with the display components.

[0148] The display component synchronously shows monitoring data from both the device-side (Programmable Logic Controller, PLC) and the remote communication terminal, including water pressure detection values, current detection values, water pressure detection status, and start / stop output status. In this application, the device-side refers to the side where the programmable logic controller is located, i.e., the local control terminal of the sprayer equipment. In the specific implementation, the interface of the data transmission component is connected to the communication interface of the central controller to achieve data interaction. The data transmission component establishes a wireless communication link with the remote monitoring platform via a 4G or 5G network.

[0149] In practical implementation, the water pressure detection value can be an AD (Analog to Digital) detection value, which refers to the digital detection value obtained after analog signals from water pressure sensors are converted from analog to digital. The current detection value can be a DA (Digital to Analog) output value, which refers to the analog control value output after control signals are converted from digital to analog.

[0150] The multi-machine status monitoring component is electrically connected to the central controller of each concrete sprayer. This component centrally displays the power-on status, operating status, water outage status, and replenishment status of multiple devices. The remote monitoring platform receives and stores water pressure data and fault warning information uploaded by the data transmission component via wireless communication.

[0151] This application integrates water pressure data, data transmission unit feedback information, and operating current data to accurately distinguish between water outage faults and filter blockage faults, avoiding ineffective maintenance operations. The display component synchronously displays equipment data from both the device itself and the remote communication terminal, allowing on-site personnel to monitor the equipment's operating status in real time.

[0152] During normal operation, when the concrete spraying machine is running, the water pressure detection component continuously collects the water pressure signal from the water supply pipeline, the data transmission component uploads the signal to the remote monitoring platform, and the display component simultaneously displays the monitoring data from both the equipment and the remote communication terminal.

[0153] During the water outage fault determination phase, if the information fed back by the data transmission component shows that there is currently no water pressure and the water pressure is not fluctuating, and at the same time the central controller obtains that the concrete surface sprayer is in the start state, the central controller determines that it is a water outage fault and triggers the corresponding warning. At this time, the water pressure detection status in the display component shows an abnormal mark, and at the same time, the abnormal status of the start and stop output is displayed.

[0154] During the filter clogging fault determination stage, if the information fed back by the data transmission component shows a decrease in water pressure, and at the same time the current detection component detects an increase in the operating current of the concrete surface sprayer, the central controller determines that it is a filter clogging fault and triggers the corresponding cleaning warning.

[0155] During the multi-machine status monitoring phase, the multi-machine status monitoring component summarizes the status data of each concrete sprayer in real time, and centrally displays the power-on status, normal operation status and water outage status of multiple devices.

[0156] When the multi-machine status monitoring component detects a faulty concrete sprayer, it activates the adjacent normally operating sprayer to fill the gap. If the water pressure is detected to be zero and the duration exceeds the first water outage duration, it is determined to be a short-term water outage, and the adjacent normally operating sprayer is activated to fill the gap. If the duration exceeds the second water outage duration, it is determined to be a continuous water outage, and the two adjacent normally operating sprayers are activated to fill the gap.

[0157] When a water pressure drop is detected within the first deviation range and fluctuates, and the operating current rise is also within the first deviation range, and the duration exceeds the first blockage duration, while the concrete surface sprayer is running, a minor blockage is identified, triggering a cleaning warning and activating a normally functioning sprayer adjacent to the faulty sprayer to fill the gap. If the duration exceeds the second blockage duration, a persistent blockage is identified, and the replacement strategy is automatically upgraded, activating two normally functioning sprayers adjacent to the faulty sprayer to fill the gap. When a water pressure drop is detected within the second deviation range and the fluctuation increases, and the operating current rise is also within the second deviation range, and the duration exceeds the first blockage duration, a severe blockage is identified, immediately triggering a cleaning warning and an emergency alarm. On-site personnel are required to handle the situation immediately, and two normally functioning sprayers adjacent to the faulty sprayer are activated to fill the gap, expanding the spray coverage and increasing the spray volume to compensate for the faulty sprayer's coverage area.

[0158] In this embodiment, after the fault is resolved, the water pressure signal collected by the water pressure detection component returns to normal, the current signal collected by the current detection component returns to normal, the central controller clears the alarm, and the linked sprayers restore their initial operating parameters. The water pressure detection status on the display component returns to the green normal indicator, and the multi-machine status monitoring component updates to normal operating status.
