[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals.

Each of the ZigBee module transmitters includes a first serial port communication module, a first microprocessor module, a first wireless transceiver module, and a first power management module, wherein: the first serial port communication module adopts RS232 serial port communication technology to realize the communication connection between the ZigBee module transmitter and the ultrasonic flow meter; the first microprocessor module adopts CC2530 chip, collects the flow data of the water pump through the first serial port communication module and feeds it back to the first wireless transceiver module.

[0004] The application aims to solve the problem that "the existing methods for monitoring water pump flow are manual timed monitoring and online monitoring using wired methods. The former cannot achieve real-time monitoring of water pump flow. Although the latter can achieve real-time monitoring, it has disadvantages such as high cost and easy aging of lines."

[0005] However, the current water pump flow monitoring technology is still limited to the self-monitoring of the liquid transmitted by the water pump. The accuracy of the water pump flow monitoring is directly related to the accuracy of the monitoring technology and the equipment used for monitoring. There is no other data reference condition to determine the safety of the water pump's operating status. Summary of the invention

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides a water pump flow monitoring system and a monitoring method based on visualization, which solve the technical problems raised in the above-mentioned background technology.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] First, the visualization-based water pump flow monitoring system includes deployment layer, collection layer and early warning layer;

[0009] The flow monitoring equipment is designed and deployed through the deployment layer. The deployed flow monitoring equipment collects the liquid flow data in the water pump in real time and feeds it back to the collection layer. The collection layer analyzes the water pump status parameters based on the received liquid flow data in the water pump. The early warning layer further receives the water pump status parameters analyzed in the collection layer, and issues early warning information in real time based on the water pump status parameters for system end users to receive.

[0010] The acquisition layer includes a receiving module, a rotation module and an analysis module. The receiving module is used to receive the liquid flow data in the water pump monitored by the flow monitoring device deployed in the deployment layer. The rotation module is used to monitor the operating state of the analysis module, and control the receiving module to perform the receiving operation of the liquid flow data in the water pump again based on the operating state of the analysis module. The analysis module is used to obtain the liquid flow data in the water pump received by the receiving module, and analyze the safety factor of the current operating state of the water pump based on the liquid flow data in the water pump.

[0011] The formula for calculating the safety factor of the water pump in its current operating state is:

[0012]

[0013] Where: Q front The liquid flow rate of the water pump last detected by the flow sensor; Q after Transmitting liquid flow rate for the water pump monitored by the flow sensor at the current stage; is the mean value of the refined results of the torque value monitored by the torque sensor last time; is the mean value of the refined results of the torque value monitored by the torque sensor at the current stage;

[0014] The flow sensor monitors the liquid flow rate transmitted by the water pump and obtains the flow rate based on the following principle:

[0015]

[0016] Where: t1 is the temperature of the liquid transmitted by the water pump; Δt is the temperature difference between the output and the output of the liquid transmitted by the water pump; h c is the static head of the water pump; e is the correction value of the mechanical loss of the water pump; h is the head of the liquid transmitted by the water pump at the output; p d0 is the water pump power;

[0017] The Z value is a water pump state parameter, Z≥0, and the smaller the Z value is, the less safe the water pump is, and vice versa.

[0018] Furthermore, the deployment layer includes a design module, a monitoring module and a storage module, the design module is used to set the parameters of the water pump configuration flow monitoring device, the monitoring module is used to monitor the liquid flow data in the water pump, and the storage module is used to receive the liquid flow data in the water pump monitored by the monitoring module and store the liquid flow data in the water pump;

[0019] Among them, the flow monitoring equipment includes: a flow sensor, a baffle, a torsion spring and a torsion sensor. The water pump configuration flow monitoring equipment parameters set in the design module are the number of flow monitoring equipment. The liquid flow data in the water pump monitored by the monitoring module is acquired through the flow monitoring equipment. The baffle is hinged inside the input and output ends of the water pump, and a torsion spring is sleeved on the hinged shaft at the hinge position of the baffle. When there is no water flow passing through the water pump, the baffle is positioned by the torsion spring. The torsion sensor is connected to the torsion spring to monitor the torque value of the torsion spring in real time.

[0020] Furthermore, the monitoring data of the flow monitoring device include: the liquid flow rate transmitted by the input and output ends of the water pump collected by the flow sensor, and the torque value of the torsion spring;

[0021] Among them, when the design module sets the parameters of the flow monitoring device configured for the water pump, the number of flow sensors set is manually set by the system end user, and several groups of baffles are arranged in a circular plate shape inside the input and output ends of the water pump. Each baffle, torsion spring and torsion sensor are set as a group, and the set number of groups obeys the following logical formula, which is:

[0022]

[0023] Where: n is the number of groups; d 内 The inner diameter of the target end of the pump, d 外 is the inner and outer diameters of the target end installed on the water pump; L is the length of the connecting pipe at the target end installed on the water pump; m is the number of bends in the connecting pipe at the target end installed on the water pump; μ is the elevation difference between the water pump and the end of the connecting pipe at the target end installed on the water pump that is far away from each other; χ is the correction coefficient, μ≥0, χ is -1, otherwise, χ is +1.

[0024] Furthermore, after the torque sensor collects the torque value of the torsion spring, it further performs refinement processing through the following formula, and the refinement formula is:

[0025]

[0026] Where: K is the torque value obtained by refinement; k is the torque value measured by the sensor in real time; n is the sensor operation cycle set; t i is the duration of the i-th group operation cycle; λ is the sensor sensing frequency; σ′-1 is the fatigue limit of the torsion spring; N is the fatigue life of the torsion spring;

[0027] in,

[0028] Where: σ′ -1 is the actual fatigue limit; K β is the state coefficient; K ε is the size factor; K c is the temperature coefficient; K σ is the stress concentration factor; σ -1 is the fatigue limit given in the torsion spring material table.

[0029] Furthermore, when the receiving module is run for the first time in the system, it receives the latest two consecutive sets of liquid flow data in the water pump stored in the storage module, and jumps to the analysis module to run. Except for the first run, the receiving module runs synchronously with the analysis module, and during the running stage of the analysis module, the rotation module controls the receiving module in real time to delete the earlier set of liquid flow data in the water pump among the two sets of liquid flow data in the water pump received last, and further receives the latest set of liquid flow data in the water pump adjacent to the undeleted liquid flow data in the water pump in the storage module, and executes the operation of transmitting to the analysis module again with the newly received liquid flow data in the water pump and the undeleted liquid flow data in the water pump.

[0030] Furthermore, when the analysis module in the collection layer runs three times in succession, the early warning layer runs at least once.

[0031] Furthermore, the early warning layer includes a comparison module and a control panel. The comparison module is used to set the safety judgment threshold and continuously receive the safety factor of the water pump operation status analyzed by the analysis module in the collection layer, and the safety judgment threshold is used to compare with the safety factor of each group of water pump operation status to determine whether the safety factor of each group of water pump operation status is within the safety judgment threshold. If the judgment result is yes, the numerical change trend of the safety factor of each group of water pump operation status is further identified. The control panel is used to obtain the safety factor of the water pump operation status, and generate a histogram of the water pump operation status safety factor through the water pump operation status safety factor;

[0032] Among them, the identification types of numerical change trends of the safety factors of the operating conditions of each group of water pumps include: gradual increase, gradual decrease and irregular change.

[0033] Furthermore, an audio module is provided in the control panel, and the audio module is used to issue an alarm audio, and the alarm audio is manually edited and set by a system user. The audio module set in the control panel triggers operation when the comparison module determines that the result is no, or recognizes that the numerical change trend of the safety factor of the water pump operating status is gradually increasing or decreasing.

[0034] Furthermore, the design module is electrically connected to a monitoring module and a storage module through a medium, the storage module is electrically connected to a receiving module through a medium, the receiving module is electrically connected to a rotation module and an analysis module through a medium, the analysis module is electrically connected to a comparison module through a medium, and the comparison module is electrically connected to a control panel through a medium.

[0035] In the second aspect, a method for monitoring water pump flow based on visualization includes the following steps:

[0036] Step 1: Install flow monitoring equipment at the input and output ends of the water pump to collect real-time flow data of liquid transmitted by the water pump through the flow monitoring equipment;

[0037] Step 11: Design and deployment phase of flow monitoring equipment;

[0038] Step 12: The water pump transmits liquid flow data and stores it;

[0039] Step 2: Obtain liquid flow data transmitted by the water pump, and calculate the operating state safety factor of the water pump based on the liquid flow data transmitted by the water pump;

[0040] Step 21: the setting stage of the logic for acquiring the liquid flow data transmitted by the water pump;

[0041] Step 3: Set a safety determination threshold, receive the calculated safety factor of the water pump operation status, and compare the safety determination threshold with the safety factor to determine whether the water pump is safe;

[0042] Step 31: If the result of step 3 is no, the control panel display and alarm stage is executed;

[0043] Step 4: If the result of step 3 is yes, the change trend identification stage of the safety factor of the water pump operation status begins.

[0044] Compared with the known public technology, the technical solution provided by the present invention has the following beneficial effects:

[0045] 1. The present invention provides a water pump flow monitoring system based on visualization. During operation, the system, through the design and deployment of flow monitoring equipment, provides monitoring data for water pump flow monitoring that is different from the prior art. The monitoring data is then used in calculations to evaluate and determine the operating status of the water pump. This data is further used as data support to monitor the water pump flow, with better detection accuracy.

[0046] 2. In the initial operation stage of the present invention, the configuration quantity of the flow monitoring equipment is designed by applying the parameter information of the water pump and its connecting pipes, so as to ensure that the flow monitoring data collected during the operation of the system can ensure the basic operation of the system. Based on this, a certain degree of maintenance effect is brought to the stable operation of the system. At the same time, the system can also provide more comprehensive safety monitoring of the operating status of the water pump through continuous judgment, and when there is an abnormal situation in the water pump, it can also provide a visual early warning effect to the users of the water pump management end in the form of audio alarm and synchronous output of the control panel.

[0055] Embodiment 1

[0056] The pump flow monitoring system based on visualization in this embodiment is as follows: Figure 1 As shown, it includes deployment layer, collection layer and early warning layer;

[0057] The flow monitoring equipment is designed and deployed through the deployment layer. The deployed flow monitoring equipment collects the liquid flow data in the water pump in real time and feeds it back to the collection layer. The collection layer analyzes the water pump status parameters based on the received liquid flow data in the water pump. The early warning layer further receives the water pump status parameters analyzed in the collection layer, and issues early warning information in real time based on the water pump status parameters for system end users to receive.

[0058] The collection layer includes a receiving module, a rotation module and an analysis module. The receiving module is used to receive the liquid flow data in the water pump monitored by the flow monitoring device deployed in the deployment layer. The rotation module is used to monitor the operating status of the analysis module, and control the receiving module to perform the receiving operation of the liquid flow data in the water pump again based on the operating status of the analysis module. The analysis module is used to obtain the liquid flow data in the water pump received by the receiving module, and analyze the safety factor of the current operating status of the water pump based on the liquid flow data in the water pump.

[0059] The formula for calculating the safety factor of the water pump in its current operating state is:

[0060]

[0061] Where: Q front The liquid flow rate of the water pump last detected by the flow sensor; Q after Transmitting liquid flow rate for the water pump monitored by the flow sensor at the current stage; is the mean value of the refined results of the torque value monitored by the torque sensor last time; is the mean value of the refined results of the torque value monitored by the torque sensor at the current stage;

[0062] The flow sensor monitors the liquid flow transmitted by the water pump and the principle of obtaining the flow is:

[0063]

[0064] Where: t1 is the temperature of the liquid transmitted by the water pump; Δt is the temperature difference between the output and the output of the liquid transmitted by the water pump; h c is the static head of the water pump; e is the correction value of the mechanical loss of the water pump; h is the head of the liquid transmitted by the water pump at the output; p d0 is the water pump power;

[0065] Among them, the Z value is the state parameter of the water pump, Z ≥ 0, and the smaller the Z value, the less safe the water pump is, and vice versa;

[0066] The deployment layer includes a design module, a monitoring module and a storage module. The design module is used to set the parameters of the water pump configuration flow monitoring device. The monitoring module is used to monitor the liquid flow data in the water pump. The storage module is used to receive the liquid flow data in the water pump monitored by the monitoring module and store the liquid flow data in the water pump.

[0067] Among them, the flow monitoring equipment includes: a flow sensor, a baffle, a torsion spring and a torsion sensor. The parameters of the water pump configuration flow monitoring equipment set in the design module are the number of flow monitoring equipment. The liquid flow data in the water pump monitored by the monitoring module is obtained through the flow monitoring equipment. The baffle is hinged inside the input and output ends of the water pump, and a torsion spring is sleeved on the hinge shaft at the hinge position of the baffle. When there is no water flow in the water pump, the baffle is positioned by the torsion spring. The torsion sensor is connected to the torsion spring to monitor the torque value of the torsion spring in real time.

[0068] After the torque sensor collects the torque value of the torsion spring, it is further refined by the following formula:

[0069]

[0070] Where: K is the torque value obtained by refinement; k is the torque value measured by the sensor in real time; n is the sensor operation cycle set; t i is the duration of the i-th group operation cycle; λ is the sensor sensing frequency; σ′ -1 is the fatigue limit of the torsion spring; N is the fatigue life of the torsion spring;

[0071] in,

[0072] Where: σ′ -1 is the actual fatigue limit; K β is the state coefficient; K ε is the size factor; K c is the temperature coefficient; K σ is the stress concentration factor; σ -1 is the fatigue limit given in the torsion spring material table;

[0073] The early warning layer includes a comparison module and a control panel. The comparison module is used to set the safety judgment threshold and continuously receive the safety factor of the water pump operation status analyzed by the analysis module in the collection layer. The safety judgment threshold is used to compare with the safety factor of each group of water pump operation status to determine whether the safety factor of each group of water pump operation status is within the safety judgment threshold. If the judgment result is yes, the numerical change trend of the safety factor of each group of water pump operation status is further identified. The control panel is used to obtain the safety factor of the water pump operation status, and generate a histogram of the water pump operation status safety factor through the water pump operation status safety factor;

[0074] Among them, the identification types of numerical change trends of the safety factors of the operating conditions of each group of water pumps include: gradual increase, gradual decrease and irregular change;

[0075] The design module is electrically connected to the monitoring module and the storage module through a medium, the storage module is electrically connected to the receiving module through a medium, the receiving module is electrically connected to the rotation module and the analysis module through a medium, the analysis module is electrically connected to the comparison module through a medium, and the comparison module is electrically connected to the control panel through a medium.

[0076] In this embodiment, the design module runs to set the parameters of the flow monitoring device configured for the water pump, the monitoring module synchronously monitors the liquid flow data in the water pump, the storage module runs post-position, receives the liquid flow data in the water pump monitored by the monitoring module, and stores the liquid flow data in the water pump. The receiving module receives the liquid flow data in the water pump monitored by the flow monitoring device deployed in the deployment layer in real time, the rotation module synchronously monitors the running status of the analysis module, and controls the receiving module to perform the receiving operation of the liquid flow data in the water pump again based on the running status of the analysis module, and then the analysis module runs to obtain the liquid flow data in the water pump received by the receiving module. The safety factor of the current operating state of the water pump is analyzed based on the liquid flow data in the water pump. Finally, the safety judgment threshold is set through the comparison module and the analysis module in the continuous receiving acquisition layer. The analyzed safety factor of the operating state of the water pump is compared with the safety factor of each group of water pumps using the safety judgment threshold to determine whether the safety factor of the operating state of each group of water pumps is within the safety judgment threshold. If the judgment result is yes, the numerical change trend of the safety factor of the operating state of each group of water pumps is further identified. The control panel obtains the safety factor of the operating state of the water pump in real time, and generates a histogram of the safety factor of the operating state of the water pump through the safety factor of the operating state of the water pump;

[0077] Through the formula for obtaining the safety factor of the water pump's current operating state recorded above, the microsystem provides a digital data reference for the water pump's flow monitoring, and provides necessary data support for the production of the water pump's operating state safety factor histogram. Moreover, by configuring the refined formula, the torque value collected by the torque sensor can be refined, making the result data finally output by the system more reliable.

[0078] See also Figures 3-4 As shown in the figure, it can be seen that the flow monitoring device is installed on the water pump, including the installation end 1, the baffle 2, the torsion spring 3, and the torsion sensor 4. Figures 3-4 , which can assist users of this technical solution to more conveniently understand the installation and deployment status of flow monitoring equipment.

[0079] Embodiment 2

[0080] In terms of specific implementation, based on Example 1, this example refers to Figure 1 The pump flow monitoring system based on visualization in Example 1 is further described in detail:

[0081] The monitoring data of the flow monitoring equipment include: the liquid flow rate transmitted at the input and output ends of the water pump collected by the flow sensor, and the torque value of the torsion spring;

[0082] Among them, when the design module sets the parameters of the flow monitoring device configured for the water pump, the number of flow sensors set is manually set by the system end user, and several groups of baffles are arranged in a circular plate shape inside the input and output ends of the water pump. Each baffle, torsion spring and torsion sensor are set as a group, and the set number of groups obeys the following logical formula, which is:

[0083]

[0084] Where: n is the number of groups; d 内 The inner diameter of the target end of the pump, d 外 is the inner and outer diameters of the target end installed on the water pump; L is the length of the connecting pipe at the target end installed on the water pump; m is the number of bends in the connecting pipe at the target end installed on the water pump; μ is the elevation difference between the water pump and the end of the connecting pipe at the target end installed on the water pump that is far away from each other; χ is the correction coefficient, μ≥0, χ is -1, otherwise, χ is +1.

[0085] The above formula can provide necessary logical support for the design and deployment of flow monitoring equipment, ensuring that the flow monitoring equipment configured for the implementation of the system and the operating monitoring data can meet the system operation requirements.

[0086] like Figure 1 As shown, when the receiving module is first run in the system, it receives the latest two consecutive sets of liquid flow data in the water pump stored in the storage module, and jumps to the analysis module for operation. Except for the first operation, the receiving module runs synchronously with the analysis module, and in the analysis module operation stage, the rotation module controls the receiving module in real time to delete the earlier set of liquid flow data in the water pump among the two sets of liquid flow data in the water pump received last, and further receives the latest set of liquid flow data in the water pump adjacent to the undeleted liquid flow data in the water pump in the storage module, and executes the operation of transmitting to the analysis module again with the newly received liquid flow data in the water pump and the undeleted liquid flow data in the water pump;

[0087] When the analysis module in the collection layer runs three times in succession, the early warning layer runs at least once.

[0088] Through the above settings, it is possible to provide logical limitations for the mutual cooperation of modules in the collection layer, ensure the stable operation of the collection layer, and provide the necessary operating conditions for the operation of the early warning layer.

[0089] like Figure 1As shown, an audio module is provided in the control panel, and the audio module is used to issue an alarm audio, and the alarm audio is manually edited and set by the system end user. The audio module set in the control panel triggers operation when the comparison module determines that the result is no, or recognizes that the numerical change trend of the safety factor of the water pump operation status is gradually increasing or decreasing.

[0090] Through the above settings, the functionality of the system is further improved, and the water pump flow monitoring effect is more comprehensive by the collaborative operation of the audio alarm and the control panel.

[0091] Embodiment 3

[0092] In terms of specific implementation, based on Example 1, this example refers to Figure 2 The pump flow monitoring system based on visualization in Example 1 is further described in detail:

[0093] The method for monitoring water pump flow based on visualization includes the following steps:

[0094] Step 1: Install flow monitoring equipment at the input and output ends of the water pump to collect real-time flow data of liquid transmitted by the water pump through the flow monitoring equipment;

[0095] Step 11: Design and deployment phase of flow monitoring equipment;

[0096] Step 12: The water pump transmits liquid flow data and stores it;

[0097] Step 2: Obtain liquid flow data transmitted by the water pump, and calculate the operating state safety factor of the water pump based on the liquid flow data transmitted by the water pump;

[0098] Step 21: the setting stage of the logic for acquiring the liquid flow data transmitted by the water pump;

[0099] Step 3: Set a safety determination threshold, receive the calculated safety factor of the water pump operation status, and compare the safety determination threshold with the safety factor to determine whether the water pump is safe;

[0100] Step 31: If the result of step 3 is no, the control panel display and alarm stage is executed;

[0101] Step 4: If the result of step 3 is yes, the change trend identification stage of the safety factor of the water pump operation status begins.

[0102] In summary, the system in the above embodiment brings monitoring data that is different from the existing technology to the flow monitoring of the water pump through the design and deployment of the flow monitoring equipment, and then brings an evaluation and judgment effect to the operating status of the water pump by participating in the calculation of the monitoring data. Further, this is used as data support to monitor the flow of the water pump, and its detection accuracy is better; and in the initial operation stage of the system, by applying the parameter information of the water pump and its connecting pipes, the configuration quantity of the flow monitoring equipment is designed, so as to ensure that the flow monitoring data collected during the operation of the system can ensure the basic operation of the system, and based on this, a certain degree of maintenance effect is brought to the stability of the system operation. At the same time, the system can also bring more comprehensive safety monitoring of the operating status of the water pump through continuous judgment, and when there is an abnormal situation in the water pump, it can also bring a visual early warning effect to the user of the water pump management end in the form of audio alarm and control panel synchronous output; at the same time, the method in the embodiment can further maintain the stability of the system operation, and the execution of the steps in the method brings a further refinement effect to the operation logic of the system, ensuring that the operation of the system is more logical.
