The present disclosure generally relates to sump pumps, and more particularly, to techniques for integrating a sump pump system into a smart home system.
A sump pump is a type of pump used to remove water that has accumulated in a lower level (e.g., a basement, a ground floor level, a sub-ground floor level, etc.) of a property (e.g., a home, an office, or any other building or structure). The sump pump sends the water into pipes that lead away from the property so that potential lower-level flooding may be avoided. As such, failures in the sump pump can have disastrous consequences including water damages and insurance losses. However, sump pump failures often occur without prior warning or may not be discovered until significant damage has already been done. Unfortunately, many currently available sump pump systems are not designed or equipped to automatically detect impending sump pump failures, or remedy such failures even if they are detected.
The described methods and systems user to manually activate or engage the pump from a remote location and/or to monitor the state of the sump pump (e.g., the water level, the pump condition, pipe conditions, etc.) when located at a remote location relative to the sump pump.
In an embodiment, a system implements remote control of a sump pump. The system may include a sump pump disposed in a sump basin and configured to pump water out of the sump basin via an outlet pipe. The system may include a sump pump control system coupled to the sump pump and configured to activate and deactivate the sump pump based on levels of water in the sump basin. The system may include a user interface device communicatively coupled to the sump pump control system. The user interface device may include a user interface element that, when interacted with by a user, causes the user interface device to transmit a command to manually activate the sump pump. The sump pump control system may be configured to receive the command and respond to receiving the command by activating the sump pump.
In an embodiment, a method for implementing remote control of a sump pump is implemented. The method may include any one or more of: detecting, at a user interface device, a user interaction with a user interface element representing an instruction to activate a sump pump; transmitting a command to manually activate the sump pump; receiving the command at a sump pump control system; and/or causing the sump pump control system to respond to receiving the command by manually activating the sump pump.
In an embodiment, a method for remote monitoring of sump pump systems is implemented. The method may include any one or more of: implementing a sump pump including a first sensor that is configured to detect water levels in a sump basin, wherein the sump pump is configured to activate and deactivate based on an output from the first sensor representing the water levels; detecting, via a second sensor, acceleration of the second sensor and generating acceleration data representing the detected acceleration; detecting, via a sump pump control system for the sump pump, an acceleration pattern in the acceleration data; detecting a sump pump condition corresponding to the acceleration pattern; generating a value for a diagnostic metric based on the sump pump condition; transmitting the value for the diagnostic metric to a user interface device; and/or displaying the diagnostic metric at the user interface device.
Note, this summary has been provided to introduce a selection of concepts further described below in the detailed description. As explained in the detailed description, certain embodiments may include features and advantages not described in this summary, and certain embodiment may omit one or more features or advantages described in this summary.
Each of the figures described below depicts one or more aspects of the disclosed system(s) or method(s), according to an embodiment. The detailed description refers to reference numerals included in the following figures.
The disclosed techniques enable for remote monitoring and control of a sump pump. A sump pump system may the disclosed techniques to enable a user to manually activate or engage the pump. This manual activation may be useful to test the pump, to verify that the pump motor is not working, or to empty the basin as desired. Further, the sump pump system may detect one or more conditions, generate a diagnostic metric representing the condition, and may transmit the diagnostic metric to a user interface device for display to the user.
Generally speaking, sump pumps are used in areas where lower level (e.g., ground level or below ground level) flooding may be a problem and/or is a recurring problem. A typical sump pump system comprises a submersible impeller type pump disposed in a sump basin. The sump basin is a holding cavity formed by digging a recess into the floor of a lower level of a property, such as a ground level or below ground level (e.g., a basement) of a property (e.g., a home, an office, or any other building or structure). The sump basin acts both to house the sump pump and to collect accumulated water. Water may accumulate in the sump basin when excessive amounts of rain, snow melt or ground water saturate the soil adjacent to the property and/or property lower level floor. Water may also enter the sump basin via drainage or inlet pipes that have been placed into the ground to divert any excess water into the sump basin before the water can begin to permeate foundation walls, floors, etc., or water may enter the sump basin through porous or cracked walls, floors, etc. Generally speaking, the sump basin is installed in a basement such that the top of the sump basin is lower than the lowest floor level in the basement. Accordingly, when the water table underneath and around the property rises, water flows into the sump basin to then be pumped away from the area, thereby avoiding the water table rising above the basement floor (which can result in leaks and flooding due to the typically porous nature of basement walls). In any event, after the sump pump basin fills and the water reaches a high-water mark, the sump pumping action of a sump pump removes the accumulated water in the sump basin via one or more outlet or discharge pipes that carries the pumped water to an area away from the property (such as into a municipal storm drain, a dry well, a water retention area, etc.), thereby avoiding potential flooding inside the building. Ideally, the sump basin fills and empties at a rate fast enough to prevent the water table from rising above the basement floor.
Turning to the figures,
The example sump pump system 100 includes a sump pump 102 located in a sump basin 104. The sump pump 102 and a sump pump motor 103 are enclosed in a housing 105. The sump pump motor 103 may also be referred to herein as the motor 103, and the sump pump 102 may also be referred to herein as the pump 102. While the sump pump 102 in
Generally, the sump pump 102 may be electrically powered and hardwired into the electrical system of the property 150. Additionally and/or alternatively, the sump pump 102 may be powered by a battery or other independent power source (not shown for clarity of illustration). The operation of the sump pump 102 is controlled by a pump activation switch 122 in response to a water level in the basin 104. For example, the sump activation switch 122 may activate the sump pump 102 when a water level in the sump basin 104 reaches a preset level. The preset level is determined by the placement of the sump pump activation switch 122. In illustrated example of
As shown in
When the sump pump 102 and/or the motor 103 fails, flooding may ensue as water fills up the sump basin 104 and overflows above the floor level 106 of the property 150. The amount of water that overflows can vary from a few inches to several feet, which may result in substantial water damage to the structures of property 150, as well as personal belongings. Accordingly, the ability to maintain sump pumps, and to detect and resolve impending sump pump failures before they occur is of great importance to the property owners and the building and property insuring parties.
The sump pump 102 may fail because of a failure in the motor 103, which renders the entire sump pump 102 inoperable. The failure in the motor 103 may be caused by various factors such as age, fatigue, overheating, poor maintenance, etc. Aside from the failure of the motor 103, the sump pump 102 may fail because of other soft mechanical failures of the components of the sump pump system 100. For example, sediment or debris build-up may cause the motor impeller 117 and/or another sump pump component to stall, thus, rendering the sump pump 102 unable to pump water even though the motor 103 is operational. Additionally or alternatively, the sump pump activation switch 122 may fail to engage in response to the rising water level and subsequently fail to actuate the motor 103. Additionally or alternatively, the check valve 114 may malfunction, and back flow of the discharged water into the sump pump basin 104 may equal or exceed the amount of water being pumped out by the sump pump 102. Additionally or alternatively, there might be a blockage in the discharge pipe 112, preventing water flow to the outlet 110. Additionally and/or alternatively, an air pocket may cause the sump pump 102 to run dry. As such, mechanisms to maintain the sump pump and/or detect impending sump pump failures may include monitoring for the occurrence of such failures.
Generally, soft mechanical failures may be identified or detected indirectly. In an embodiment, soft mechanical failures may be detected by using properly placed sensors, such as sensors 124, 126, 128, 130, 132, and 134 of
Example remedies to soft mechanical failures (such as a blockage or stuck impeller) may include activating a shaker, altering a speed of a pump impeller, reversing a direction of spin of the pump impeller, gradually accelerating the impeller, or alternating gradual accelerations of the impeller with gradual decelerations. If desired, the sump pump system 100 may include a variable speed motor or controller for the sump pump 102. In an embodiment, the sump pump motor 103 is a variable speed motor; in an embodiment, it is not. Similarly, in an embodiment, the sump pump controller 138 is a variable speed controller; in an embodiment, it is not.
For example, in embodiments in which the pump impeller is reversed or adjusted in speed, a variable speed motor or controller may be included for controlling the pump and/or pump impeller in such a manner. In some embodiments, a variable speed motor or controller may detect a blocked impeller by sensing that the position of the rotor or impeller is not changing even though power is applied. To dislodge the mechanical blockage, the controller may spin the motor in reverse direction or alternate gradual acceleration with gradual deceleration in opposite directions. Gradual acceleration upon motor activation and gradual deceleration upon motor disengagement may reduce initial step level force impact of the pump turning on or off, which may benefit the system by lengthening the serviceable life of the motor and the marginal pipe infrastructure.
As shown in
The sensor 124 may be a water level sensor, placed a short distance (e.g., 10, 20, 30, or 50 mm above) above the high water level or mark 142 in the sump basin 104. In operation, if the water level sensor 124 does not detect water, then the water level in the basin 104 is deemed adequate. In other words, the sump pump 102 is either working properly to constantly pump water out of the basin 104, or the water level is not yet high enough to activate the sump pump 102. In any event, it can be assumed that the sump pump 102 is not experiencing any soft mechanical failure. On the other hand, if the water level sensor 124 detects water, then water may be on the rise in the basin 104, and may overflow the sump basin 104. In other words, a dangerous level of water is present in the sump basin 104, which may be due to either a failure of the sump pump 102, a failure to activate the sump pump 102, and/or a soft mechanical failure that has rendered the sump pump 102 unable to pump out adequate amount of water.
The sensor 124 may include magnetic or mechanical floats, pressure sensors, optical, ultrasonic, radar, capacitance, electroconductive and/or electrostatic sensors. The sensor 124 may be a continuous or a point level switch. A continuous liquid level switch or sensor provides a continuous feedback showing liquid level within a specified range. A point level switch detects whether a liquid level is above or below a certain sensing point. In embodiments, the sensor 124 may be a reed switch, or a mercury switch, a conductive level sensor, and/or any type of a suitable switch that changes a state from inactive to active as liquid level reaches a certain level relative to the switch position.
In some embodiments, the sensor 124 may be a continuous liquid level switch providing a measurement of the height of the water level inside the sump basin 104. The controller 138 can use these measurements, taken at time intervals (e.g., at 1, 5, or 10 second intervals), to estimate the volume of water being pumped, deposited, or backflowing in the sump basin 104. For example, knowing the sump pump basin 104 dimensions, such as a diameter (if the basin is a cylinder), or the bottom diameter, a top diameter, and a height (if the basin is a graduated cylinder) or width and length measurements (if the basin is a rectangular prism), and water level height over time will yield a measurement of water volume increase or decrease over time. The controller 138 may utilize any suitable volume formula to calculate changes in volume (e.g., volume=×r2 h for a cylinder). For example, if the basin 104 is a cylinder basin, the controller 138 may be programmed to assume a known radius (e.g., 8 inches). The controller 138 may identify the distance from the bottom of the basin 104 to the water level (e.g., based on a water level sensor). This distance may be used for the “h” variable in the volume formula, enabling the controller 138 to calculate volume at any given time it can detect the “height” of the water level. In some instances, the controller 138 may be configured to account for displacement that occurs due to the pump itself being submerged within water. For example, a known volume of the pump (which is generally static) may be subtracted from a formula that assumes a perfect cylinder.
Additionally, knowing the sump basin 104 capacity (e.g., in gallons) and water volume increase over time, the controller 138 may calculate an estimate of when the sump pump basin may overflow. For example, in a sump basin with a capacity of 26 gallons and an initial water volume of 0 gallons, the controller 128 may calculate that a water volume increase at 0.1 gallons per second would result in a sump basin overflow in 260 seconds or 4 minutes and 20 seconds. The sump pump controller 138 may generate an alert, communicating an approximated time of the critical event of the sump basin 104 overflowing, or communicating the time (e.g., in minutes or seconds) remaining until the estimated overflow.
Additionally, functions of the sump pump controller 138 of
The sensor 126 may be a force sensor or transducer, configured to detect a water rise or fall rate in the sump basin 104, or water disturbance (e.g., splashing) in the sump basin 104. The sensor 126 may be, for example a piezoelectric crystal, a pneumatic, a hydraulic, an inductive, a capacitive, a magnetostrictive, or a strain gage load cell, or an accelerometer, or any other suitable sensor capable of transducing a force into an electrical signal. In an embodiment, an accelerometer of the sensor 126 measures inertial acceleration, from which water rise rate in the sump basin 104 can be determined.
The sensor 126 may be placed above the initial or low water level or mark 140 and, for example, below the high water level or mark 142 in the sump basin 104. Alternatively, the sensor 126 may be placed above the high water level or mark 142 in the sump basin 104.
In operation, a rising water level in the sump basin 104 would exert a load on the sensor 126, from which a rise or fall rate of the water level in the sump basin 104 can be determined. If the sensor 126 does not detect any force exerted on it, there may be no water at the level of the sensor 126. Alternatively, the water level at the sensor 126 in the sump basin 104 may be constant. In other words, water rise rate, or inflow rate may equal the rate of water pumped out through the discharge pipe 112 by the sump pump 102. In an alternative scenario, the sensor 126 may sense an upward force of the rising water level when the sump pump 102 is operational, and an inlet sensor 130 (described later in more detail) detects water entering the sump basin 104 from the inlet 108, indicating that the inflow rate is greater than the rate of water pumped out through the discharge pipe 112 by the sump pump 102. In yet another scenario, the sensor 126 may sense rising water, the inlet sensor 130 may not detect any water inflow into the sump basin 104, and at the same time the sump pump 102 may be engaged, the scenario indicating that the water level is rising due to additional inflow (e.g., back flow from the discharge pipe, or the vent 120, or through the floor 106 opening of an uncovered sump basin).
The sump pump system 100 may include a vibration sensor 128, placed in direct or indirect contact with the sump pump 102 or pump motor 103.
The inlet sensor 130 and the outlet sensor 132 of the sump pump system 100 may be water level sensors, analogous to the water level sensor 124. In operation, the sensor 130 detects presence of water in the inlet pipe 108, or inflow. If the sensor 130 does not detect water in the inlet pipe 108, there is no water flowing into the sump basin 104 via the inlet pipe 108.
The outlet sensor 132 detects presence of water in the discharge pipe 112 before the check valve 114, monitoring whether the check valve 114 is working properly, i.e., preventing the back flow of water into the sump basin 104 when the motor 103 is disengaged and the sump pump 102 is not operating.
The sensor 134 may be a water level sensor, placed at a level or mark 136 in the sump basin 104 corresponding to the bottom 137 of the impeller 117 and/or another sump pump component of the sump pump 102, which is below the low or initial water level or mark 140. In operation, if the sensor 134 does not detect water, then the current water level in the basin 104 may be deemed adequately low to avoid, prevent, reduce, etc. corrosion of the impeller 117 and/or another sump pump component due to standing water in the sump basin 104. On the other hand, if the water level sensor 134 detects water, then at least a portion of the impeller 117 and/or another sump pump component may be currently exposed to water and a condition for potential corrosion may exist. Alternatively, the sensor 134 may be a force sensor or transducer and configured to detect a water rise or fall rate, water movement (e.g., a disturbance, splashing, sloshing, ripples, etc.) in the sump basin 104 due to the sump pump 102 running, etc. at the level or mark 136.
The sensor 134 may include magnetic or mechanical floats, pressure sensors, optical, ultrasonic, radar, capacitance, electroconductive or electrostatic sensors. The sensor 134 may be a continuous or a point level switch. A continuous liquid level switch or sensor provides a continuous feedback showing liquid level within a specified range. A point level switch detects whether a liquid level is above or below a certain sensing point. In some embodiments, the sensor 134 may be a reed switch, or a mercury switch, a conductive level sensor, or any type of a suitable switch that changes a state from inactive to active as liquid level reaches a certain level relative to the switch position.
Each of the sensors 124, 126, 128, 130, 132, and 134 may include one or more associated circuits, as well as packaging elements. The sensors 124, 126, 128, 130, 132, and 134 may be electrically or communicatively connected with each other (e.g., via one or more busses or links, power lines, etc.), and may cooperate to enable “smart” functionality described within this disclosure.
The sump pump system 100 may include a mechanical shaker 101 that is physically attached to the sump pump 102 and/or the discharge pipe 112. When engaged, the shaker 101 vibrates at a given frequency for the purpose of transferring motion to the sump pump 102 or the discharge pipe 112 in order to cause the pump 102 or the discharge pipe 112 to vibrate in a manner sufficient to “break loose” a blockage that is blocking the impeller 117 or the pipe 112. The mechanical shaker 101 may be in the form of an electromechanical vibration device (e.g. a linear motor) that physically agitates or shakes the sump pump. The intensity and duration of the vibration produced by the mechanical shaker 101 may be set or adjusted as desired. For example, the mechanical shaker 101 may be set to vibrate intensely and continuously for a short burst of time. As another example, the mechanical shaker 101 may be set to vibrate in multiple operating cycles (e.g., 3 or 5 cycles), with each cycle producing a different level of vibration intensity (e.g., an increase in the level of intensity going from the first cycle to the last cycle). Further, different types of vibration profiles may be specified such as a sine sweep, random vibration, synthesized shock, etc. The mechanical shaker 101 may be a standalone unit that may be retrofitted or added to the sump pump 102. In some embodiments, the mechanical shaker 101 may be integrated with or be part of the sump pump 102. Further, both the mechanical shaker 101 and the water level sensor(s) in the system 100 may be connected to the controller 138 so that the controller 138 can control the operation of the mechanical shaker 101 and the water level sensor(s).
The mechanical shaker 101 may be automatically activated in response to detected soft mechanical failures, such as when water overflow is detected by water level sensor or when the motor 103 runs too long in the absence of any water overflow detection. The mechanical shaker 101 may also be automatically activated in response to the controller 138 detecting potential problems with the motor 103. For example, the controller 138 may detect a vibration or acceleration pattern (e.g., of the water or of the sump pump or sump pipe) indicative of a problem (e.g., a blockage), and may respond by activating the shaker 101.
In some examples, the sump pump controller 138 maintains, tests, etc. the sump pump system 100 by periodically (e.g., every 14 days) running the motor 103 for at least a short duration (e.g., 30 seconds), regardless of the amount of water in the sump basin 104.
To reduce, avoid, prevent, etc. corrosion of the impeller 117 due to extended exposure of the impeller 117 to standing, potentially dirty water, in some examples, the sump pump controller 138 periodically activates the motor 103 (e.g., every 14 days) until the level of water in the sump basin 104 as detected by, for example, the sensor 134 is below the bottom 137 of the impeller 117. When the sensor 134 is a level sensor, the level of water in the sump basin 104 may be detected as being below the impeller 117 when the sensor 134 fails to sense any water. When the sensor 134 is a force sensor, the level of water in the sump basin 104 may be detected as above the bottom 137 of the impeller 117 when the sensor 134 senses a falling water level, water movement (e.g., sloshing, splashing, ripples, etc.) due to pump vibrations, etc.
Additionally and/or alternatively, following a water event, the sump pump controller 138 runs the motor 103 until a current level of the water in the sump basin 104 as detected by, for example, the sensor 134 is below the bottom 137 of the impeller 117 and/or another sump pump component. Example water events include, but are not limited to, a storm, a flood, a plumbing failure, etc. that initially causes an initial inrush of incoming water, followed by a slower flow of incoming water. An example method of detecting a water event includes: (i) during a first time period, detecting that a rate at which water is rising in the sump basin exceeds a first threshold; (ii) during a second, later time period, detecting that a rate at which water is rising in the sump basin 104 is less than a second, lower threshold; and (iii) optionally detecting that water has stopped rising in the sump basin. In some examples, the force sensor 126 is configured to determine the water rise rate in the sump basin 104. The rate at which water is rising in the sump basin 104 may, additionally and/or alternatively, be determined by counting the number of activations of the motor 103 in a period of time to, for example, maintain a current level of water in the sump basin 104 below the water level or mark 142.
As shown in the illustrated example of
The sump pump controller 138 may convey data, updates, alerts, etc. related to the sump pump system 100 to a smart home hub 152 at the property 150 via any number and/or type(s) of local network(s) 154. The smart home hub 152 may connect to smart home devices (e.g., the sump pump controller 138, the sump pump system 100, doorbells, lights, locks, security cameras, thermostats, etc.) to enable a user 156 (e.g., a homeowner) to install, configure, control, monitor, etc. such devices via an electronic device 158, such as a smartphone, a tablet, a personal computer, or any other computing device. In some embodiments, the smart home hub 152 may send alerts, updates, notifications, etc. when certain conditions occur (e.g., when the sump pump controller 138 detects potential failure conditions) to the user 156 via their electronic device 158. Additionally and/or alternatively, alerts, status updates, notifications, etc. may be provided remotely via any number and/or type(s) of remote network(s) 162, such as the Internet. Thus, the user 156 may receive alerts, status updates, notifications, etc. via their electronic device 158 both when they are at the property 150 and when they are away. Moreover, alerts, status updates, notifications, etc. may be sent to a remote processing server 164 (e.g., a server or servers associated with insurance provider or providers) via the remote network(s) 162 for remote monitoring, control, etc.
While examples disclosed herein are described with reference to the sump pump controller 138 receiving and processing data from the sensors 124, 126, 128, 130, 132 and 134 to maintain and/or detect failures of the sump pump system 100, additionally and/or alternatively, data from the sensors 124, 126, 128, 130, 132 and 134 may be sent to the remote processing server 164 for processing to control, maintain and/or detect failures of the sump pump system 100, etc. In some examples, the remote processing server 164 may be part of security system monitoring server.
In some examples, data from the sensors 124, 126, 128, 130, 132 and 134, and/or alerts, status updates, notifications, trends, etc. determined by the sump pump controller 138 are stored in a cache, datastore, memory, etc. 140 for subsequent recall.
While the example sump pump controller 138 and/or, more generally, the example sump pump system 100 for monitoring sump pumps for failures and/or maintaining sump pumps are illustrated in
The computing system 200 includes, among other things, a processor 202, memory 204, input/output (I/O) interface(s) 206 and network interface(s) 208, all of which are interconnected via an address/data bus 210. The program memory 204 may store software and/or machine-readable instructions that may be executed by the processor 202. It should be appreciated that although
The memory 204 may include volatile and/or non-volatile memory(-ies) or disk(s) storing software and/or machine-readable instructions. For example, the program memory 204 may store software and/or machine-readable instructions that may be executed by the processor 202 to implement the sump pump controller 138 and/or, more generally, the sump pump system 100. In some examples, the memory 204 is used to store the datastore 140.
Example memories 204 include any number or type(s) of volatile or non-volatile tangible, non-transitory, machine-readable storage medium or disks, such as semiconductor memory, magnetically readable memory, optically readable memory, a hard disk drive (HDD), an optical storage drive, a solid-state storage device, a solid-state drive (SSD), a read-only memory (ROM), a random-access memory (RAM), a compact disc (CD), a CD-ROM, a DVD, a Blu-ray disk, a redundant array of independent disks (RAID) system, a cache, a flash memory, or any other storage medium or storage disk in which information may be stored for any duration (e.g., permanently, for an extended time period, for a brief instance, for temporarily buffering, for caching of the information, etc.).
As used herein, the term non-transitory, machine-readable medium is expressly defined to include any type of machine-readable storage device and/or storage disk, to exclude propagating signals, and to exclude transmission media.
The processing platform 200 of
The I/O interface(s) 206 of
The network interface(s) 208 enable communication with other systems (e.g., the smart home hub 152 of
To provide, for example, backup power for the example sump pump controller 138 and/or, more generally, the example sump pump system 100, the example computing system 200 may include any number and/or type(s) of battery(-ies) 212.
To determine the time between events, the example computing system 200 includes any number and/or type(s) of timer(s) 214. For example, a timer 214 may be used to periodically trigger (e.g., every 14 days) the activation of the motor 103 for maintenance purposes. A timer 214 may, additionally and/or alternatively, be used to determine the rate at which water is rising in the sump basin (e.g., number of activations of the motor 103 required) during a period of time.
This may be useful to test the pump, to verify that the pump motor is not working, or to empty the basin as desired. The method 300 may be implemented, in whole or in part, by any suitable controller or system such as the sump pump controller 138 shown in
At a step 305, a user interface device (e.g., the device 158) detects a user interacting with a user interface element (e.g., a graphic element on a touchscreen) representing an instruction to activate a sump pump (e.g., the pump 102) in a sump pump system (e.g., the system 100). In some instances, the user interface element may be a hardware element (e.g., a keyboard key, a mouse button etc.).
At a step 310, a sump pump controller (e.g., the controller 138) for the sump pump transmits a command to manually activate a sump pump (e.g., the pump 102). The controller may activate the pump by activating the pump motor (e.g., the motor 103).
At a step 315, a sump pump controller (e.g., the controller 138) of the sump pump system receives the command from the user interface device.
At a step 320, the sump pump controller responds to receiving the command by activating the sump pump. In some embodiments, the controller may deactivate the sump pump when a low-water mark is detected. The low-water mark may be detected via typical means (e.g., the float sensor) or via one or more acceleration patterns that the controller estimates correspond to the low-water mark. In some embodiments, the controller may deactivate the sump pump when a certain amount of time has passed (e.g., in case the float sensor is defective). In some embodiments, the controller is configured to continuously cycle operation of the sump pump on a time-based schedule after receiving the command (e.g., if the float sensor is defective). In some instances, the sump pump controller may respond to receiving the command by transmitting a water level to the user interface device (e.g., a water level at the time the command was received and/or a water level detected after the pump has engaged and disengaged).
At a step 405, a sump pump (e.g., the sump pump 102) is implemented. The sump pump may be configured to operate based on water levels detected via a first sensor, such as the float switch 122 shown in
At a step 410, a sump pump controller (e.g., the controller 138) for the sump pump (e.g., the sump pump 102) detects acceleration of a second sensor (e.g., the sensor 128) that is caused by movement of the sump pump or discharge/outlet pipe to which it is attached.
At a step 415, the sump pump controller analyzes acceleration data, representing the detected acceleration (e.g., over a period of time), to identify one or more acceleration or vibrations patterns.
At a step 420, the controller detects a correlation between the identified one or more acceleration patterns detected from a sensor mounted on a sump pump or a sump pipe (e.g., the sensor 128) and one or more sump pump conditions corresponding to the identified patterns. The controller may do this by comparing the identified patterns to a plurality of patterns stored to a record at a memory (e.g., to a memory such as the memory 204 of, for example, the hub 152, the server 162, or the server 164), wherein the record links each of the plurality of patterns to a condition, for example. For example, a first vibration pattern or signature may represent a dry pumping condition; a second vibration pattern or signature may represent a faulty switch or sensor for detecting levels (e.g., at high-water and low-water marks at which the sump pump should engage and disengage); a third vibration pattern or signature may represent a faulty bearing; a fourth vibration pattern or signature may represent a stuck impeller; a fifth vibration pattern or signature may represent a failure to engage or activate the sump pump; and a sixth vibration pattern or signature may represent a geyser effect. Any desired number of conditions may be detected via vibration signatures, to the extent the vibration signatures are distinguishable. In some embodiments, the controller may implement machine learning techniques to detect different patterns (e.g., based on training procedures involving analyzing various water signature patterns and known conditions).
As another example, the sump pump controller may analyze acceleration data detected via a sensor disposed in the sump basin such that it floats or partially floats in the water (e.g., the sensor 126 shown in
As another example, the controller may identify an acceleration pattern (sometimes called water vibration pattern or ripple pattern) indicative of a current water level based on data from the sensor 126. The controller may do this by comparing a detected ripple pattern to known ripple patterns that are stored to memory as being associated with various levels. In an embodiment, the controller detects a transition in ripple patterns that indicates a water inlet pipe has become at least partially submerged by water. Due to at least some of the in-flow being under water, this may result in a detectable change in water movement in the sump basin. Further, because the height of the inlet pipe(s) within the sump basin are constant, the controller may be programmed to estimate that the water level is at this known level when the transition is detected. In some embodiments, the controller may implement machine learning techniques to detect these transitions and estimate a water level (e.g., based on training procedures involving analyzing various water signature patterns and known sump basin levels).
In any event, in some instances, the controller may determine that the estimated water level is at a level indicative of a potential fault in the first sensor. For example, the controller may determine that either a high-water mark or a low-water mark has been crossed but not detected by the first sensor. In embodiments in which the first sensor is configured to detect other water levels (e.g., 50% full), the controller may likewise determine that the 50% mark has been crossed but not detected by the first sensor.
In some embodiments, the controller 138 may assess the sump pump system condition by analyzing motor control characteristics such as current draw and pump motor 103 rotation speed. Based on the analysis, the controller 138 may determine whether the pump 102 is pumping water or air. The controller 138 can utilize the dry/submerged status of the pump 102 to calculate a fill rate and/or a level of water (e.g., without directly sensing a water level via a level sensor).
For example, the controller 138 may calculate (or be configured to store) a high-water volume (i.e., the volume of water in the basin when the water reaches the high-water mark). Similarly, the controller 138 may calculate (or be configured to store) a dry-pump volume (i.e., the volume of water in the basin when the water drops low enough to result in the pump 102 pumping air rather than water). The difference between the high-water volume and the dry-pump volume may be referred to as the delta volume (the controller 138 may be configured to store the delta volume, or it may be configured to calculate the delta volume). For example, the delta volume may be 2.5 gallons. The controller 138 may detect when the high-water volume exists (because the time at which the pump 102 is activated is likely the same time at which the high-water volume is achieved). Further, using the described techniques, the controller 138 may detect a moment at which an active pump or impeller starts pumping air instead of water. The controller 138 may calculate the time (e.g., 30 seconds or ½ minute) between these two moments and may divide the known delta volume (e.g., 2.5 gallons) by the calculated time (½ minute) to arrive at a fill rate (e.g., 5 gallons per minute).
Further, the controller 138 may utilize the calculated fill rate to estimate the level in the basin. For example, the controller 138 may start a timer when the water level reaches a known sensed level. For example, the low-water mark may be a known height. After a level sensor detects the low-water mark (e.g., the mark at which the pump 102 typically stops pumping), it may start the timer to track a time and may multiply the time by the fill rate to estimate the level at the time. This may be done multiple times if desired (e.g., continuously). Likewise, the controller 138 may be configured to store a known height just below the pump or impeller (i.e., the “dry-pump mark”). The controller 138 may utilize the disclosed techniques to detect (e.g. via motor control characteristics or power/current draw) a moment at which the pump starts to dry pump. The controller 138 may then assume the water level is at the dry-pump mark, and may utilize a timer and the fill rate to calculate or track an estimated water level (e.g., continuously if desired). The estimated water level may be used as a secondary or back-up level tracking (e.g., in case the primary level sensor faults). In other words, if an estimated water level indicates the water is above the high-water mark and a primary level sensor has not detected water at the high-water mark, the controller 138 may nevertheless activate the pump 102 to prevent flooding. If desired, the controller 138 may generate an alarm to notify someone (e.g., a user 156 or a home insuring party) that the level sensor may be faulty. Using motor characteristics change over time to determine water rise rate in the sump basin 104 can be used in addition to or instead of detecting a correlation between the identified one or more acceleration patterns detected from a sensor mounted on a sump pump or a sump pipe (e.g., the sensor 128) and one or more sump pump conditions corresponding to the identified patterns.
As another example, the controller may determine that one or more water vibration patterns detected via the second sensor indicate a particular in-flow or range of in-flow. The controller may calculate an expected duration to the high-water mark based on this estimated in-flow, and may trigger activation of a timer. When the timer indicates the duration of time has been exceeded (e.g., potentially including a buffer of time), the controller may conclude that the high-water mark has potentially or likely been exceeded.
In some instances, the controller may determine that the estimated water level confirms that the first sensor is functional and accurate. For example, the controller may determine that the first sensor detected a high-water mark and that the second sensor detected a vibration pattern of water consistent with known water vibration patterns typically present at a high-water mark.
Returning to
At a step 430, the controller may transmit (e.g., via the network 154) the value for the diagnostic metric to a user interface device (e.g., the device 158). In some embodiments, the controller may transmit a trigger for ordering of replacement sump pump system components to the user device. The trigger may be, for example, a push notification to the user device linked to the user's (e.g., the user 156) account with an online retailer of the user's choice. The notification may be an alert requiring the user's approval to complete the order.
At the step 435, the user interface device may display the value of the diagnostic metric to a user. In some instances, the value is displayed via a push notification. Depending on the metric and state of the sump pump, the user interface device and/or one or more devices connected to the network 154 and/or smart home hub 152 may generate an alarm.
In some embodiments, the controller may learn the sump pump conditions (e.g., water levels) that correspond to certain acceleration patterns by way of a machine learning model. For example, training data may be used to develop the model. The training data may include or represent features or patterns (e.g., acceleration patterns or water capacitance values) that are labeled according to known conditions corresponding to those patterns (e.g., water levels in a sump basin).
