Description

[0001] Usage and terminology

[0002] In the present disclosure, unless specified otherwise and / or unless the specific context clearly dictates otherwise, an element having an undefined number means that there is at least one of the element. Technical Field

[0003] The present disclosure generally relates to flow-charged smart water valves. Background Art

[0004] A smart water valve device can be installed to regulate the flow of water through a pressurized water source (e.g., a pressurized water supply line or water pipe). For example, the smart water valve device can include a water valve, and when the water valve is open, the smart water valve device enables downstream water to flow through the pressurized water source. When the water valve is closed, the smart water valve device blocks downstream water from flowing through the pressurized water source. The smart water valve device can open or partially open the water valve in response to a wireless command. For illustration, the smart water valve device can monitor a wireless communication channel to obtain a data packet commanding the smart water valve device to open the water valve. In response to receiving the data packet, the smart water valve device can generate a signal to open the water valve and enable downstream water to flow through the pressurized water source.

[0005] Continuously monitoring the wireless communication channel for data packets can increase the discharge rate of the battery that powers the smart water valve device. In addition, constantly opening and closing the water valve can increase the discharge rate of the battery. As a result, the battery life may be relatively short, resulting in the need for frequent battery replacement. Summary of the invention

[0018] I. Overview

[0019] In order to improve the battery life of the battery, an energy generation device is installed downstream of the water valve and within the pressurized water source. The energy generation device can be included in the smart water valve device or can be a separate device electrically coupled to the smart water valve device. When the smart water valve device opens the water valve to allow downstream water to flow through the pressurized water source, the downstream water flow applies a mechanical force to the energy generation device, which in turn causes the energy generation device to generate electricity to charge the battery.

[0020] As a non-limiting example, the energy generating device can include a turbine and a generator. When the smart water valve device opens the water valve to allow downstream water to flow through the pressurized water source, the downstream water flow causes the turbine to move (e.g., rotate or turn). Based on the movement of the turbine, the generator generates electricity and is fed to the battery, which charges the battery by this mechanism. It should be understood that the turbine is only an example of an energy generating device and is not intended to be limiting. As described below, other energy generating devices can be used to charge the battery.

[0021] Thus, the technology described herein extends the battery life of a battery powering a smart water valve device by enabling an energy generating device to charge the battery each time the water valve is at least partially opened. As a result, the battery has a longer service life, thereby reducing the frequency with which a user needs to replace the battery. Furthermore, by implementing this "self-charging" feature, the smart water valve device can be installed in a location that is not near an electrical outlet. For example, since the life of the battery can be extended by using the smart water valve device (e.g., by opening the water valve), an electrical outlet and corresponding power cord are not required to power the smart water valve device.

[0022] Below, this document will describe specific embodiments with reference to the accompanying drawings. In the specification, common features are represented by common reference numerals throughout the accompanying drawings. In some figures, multiple instances of a particular type of feature are used. Although these features are physically and / or logically different, each feature uses the same reference numeral, and different instances are distinguished by adding letters to the reference numerals. When features are referred to herein as a group or a type (for example, when a specific one of the features is not mentioned), a reference numeral without a distinguishing letter is used. However, when a specific feature of multiple features of the same type is referred to herein, a reference numeral with a distinguishing letter is used. For example, referring to Figure 5 , multiple smart water valve devices are shown, which are associated with reference numerals 110A and 110B. When referring to a specific one of these smart water valve devices, such as the smart water valve device 110A, the distinguishing letter "A" is used. However, when referring to any one of these smart water valve devices or referring to these smart water valve devices as a group, the reference numeral 110 is used without a distinguishing letter.

[0023] II. Example Smart Water Valve Device

[0024] Figure 1 is a diagram of an example system 100 including a smart water valve device. For example, the system 100 includes a smart water valve device 110 that can regulate water flow by operating in a first state (e.g., a closed water valve state) or a second state (e.g., an at least partially open water valve state). It should be understood that the second state also includes a fully open water valve state. Figure 1 In the first example 102A shown, the smart water valve device 110 is operating in a first state, wherein the water valve 120 of the smart water valve device 110 is closed. Figure 1 In the illustrated second example 102B, the smart water valve device 110 is operating in a second state, wherein the water valve 120 is at least partially open (or fully open).

[0025] The smart water valve device includes a memory 112, a controller 114, a wireless transceiver 116, a battery 118, and a water valve 120. The memory 112 can correspond to a non-transitory computer-readable medium that stores instructions 113 executable by the controller 114 (e.g., a processor) to perform the operations described herein. In some embodiments, the smart water valve device 110 includes an energy generation device 122. In other embodiments, the energy generation device 122 is located outside the smart water valve device 110. Therefore, although Figure 1 The energy generation device 122 is shown to be included in the smart water valve device 110 , but in some embodiments, the energy generation device 122 can be located outside the smart water valve device 110 and electrically coupled to the smart water valve device 110 .

[0026] The smart water valve device 110 can be configured to regulate a water flow 162 from a pressurized water source 160. According to example 102, the pressurized water source 160 can correspond to a water pipe, a water tank, a water supply line, or any other source that generates water pressure. It should be understood that the pressurized water source 160 is not limited to a domestic water source, such as a water pipe. In some embodiments, the pressurized water source 160 can correspond to an external water source, such as a water tower, an external water supply line, etc.

[0027] In order to regulate the water flow 162, the water valve 120 of the smart water valve device 110 can be switched between a closed state (as shown in the first example 102A) and an open state (as shown in the second example 102B). When the water valve 120 is in the closed state, as shown in the first example 102A, the water flow 162 is blocked by the smart water valve device 110. However, when the water valve 120 is at least partially opened, as shown in the second example 102B, the water flow 162 passes through the smart water valve device 110 (e.g., through the water valve 120) and continues to flow downstream 190. It should be understood that in the second example 102B, the water valve 120 can be partially opened or fully opened. If the water valve 120 is fully opened, the strength of the water flow 162 downstream 190 of the smart water valve device 110 is stronger than the strength of the water flow 162 when the water valve 120 is partially opened.

[0028] The controller 114 of the smart water valve device 110 includes a water valve control unit 130, a battery life monitor 132, an elapsed time monitor 134, a wireless data communication channel monitor 136, a leak detection unit 138, and a downstream smart water valve device battery life monitor 140. The operations associated with the leak detection unit 138 will be combined with Figure 2 To describe in more detail, the operations associated with the downstream smart water valve device battery life monitor 140 will be combined with Figure 3 136, 138, 140 of the controller 114. In some embodiments, one or more of the components 130, 132, 134, 136, 138, 140 of the controller 114 can be implemented using dedicated hardware. As a non-limiting example, one or more of the components 130, 132, 134, 136, 138, 140 of the controller 114 can be implemented using an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA) device. In some embodiments, one or more of the components 130, 132, 134, 136, 138, 140 of the controller 114 can be implemented using executable software. As a non-limiting example, operations associated with one or more of the components 130, 132, 134, 136, 138, 140 of the controller 114 can be performed by executing instructions 113 stored in the memory 112.

[0029] In some embodiments, one or more of the components 130, 132, 134, 136, 138, 140 of the controller 114 are optional. As a non-limiting example, in some embodiments, the controller 114 may not include a downstream smart water valve device battery life monitor 140. As another non-limiting example, in some embodiments, the controller 114 may include a battery life monitor 132 and may not include an elapsed time monitor 134. However, in other embodiments, the controller 114 may include an elapsed time monitor 134 and may not include a battery life monitor 132.

[0030] The water valve control unit 130 can be configured to generate a control signal 131 to at least partially open the water valve 120. For example, if the water valve 120 is closed (as shown in the first example 102A), in order to at least partially open the water valve 120 to allow the water flow 162 to flow downstream 190 of the smart water valve device 110 (as shown in the second example 102B), the water valve control unit 130 can generate a control signal 131 and send the control signal 131 to the water valve 120.

[0031] Although partially opening the water valve 120 may be useful for regulating the water flow 162, saving energy, and extending the life of the battery 118, in some embodiments, the water valve 120 can be completely closed or completely opened. For example, partially opening the water valve 120 may cause the smart water valve device 110 to utilize processing components and resources to prevent the water valve 120 from being completely closed or completely opened. Due to the utilization of these processing components and resources, in some cases, partially opening the water valve 120 may use energy that could have been saved if the water valve 120 was fully opened. However, in order to fully open the water valve 120, the controller 114 must default to "at least partially opening" the water valve 120. Therefore, when the phrase "at least partially opening" the water valve 120 is used herein, it also includes the situation where the water valve 120 is fully opened.

[0032] In some cases, the water valve control unit 130 can generate a control signal 131 that at least partially opens the water valve 120 in response to the wireless instruction. For illustration, the wireless transceiver 116 can be configured to wirelessly receive data packets via a wireless network. As a non-limiting example, the wireless transceiver 116 can be an Institute of Electrical and Electronics Engineers (IEEE) 802.11 ("Wifi") transceiver that receives Wifi data packets over a Wifi network. Although the smart water valve device 110 is shown as including the wireless transceiver 116, in some embodiments, a separate wireless receiver and / or a separate wireless transmitter can be integrated into the smart water valve device 110. The wireless data communication channel monitor 136 can be configured to monitor the wireless data communication channel (associated with the wireless transceiver 116) for at least one data packet that includes a command to at least partially open the water valve 120. For example, a user can wirelessly send a command to the smart water valve device 110 to open the water valve 120. The wireless data communication channel monitor 136 can monitor the wireless data communication channel to determine whether the wireless transceiver 116 receives a command (eg, a data packet). In response to detecting the command (eg, a data packet), the water valve control unit 130 can generate a control signal 131 to at least partially open the water valve 120.

[0033] However, the wireless data communication channel monitor 136 can consume power by continuously monitoring the data packets in the wireless data communication channel. In addition, by opening and closing the water valve 120, additional power can be consumed at the smart water valve device 110. Therefore, if the smart water valve device 110 is powered by a battery 118, the battery 118 may be discharged at a relatively fast rate due to the above-mentioned power-consuming operations at the smart water valve device 110. In order to improve or extend the service life of the battery 118, the technology described herein uses the energy generation device 122 to charge the battery 118 based on the water flow 162.

[0034] To illustrate, as described above, in response to at least partially opening the water valve 120, the water flow 162 from the pressurized water source 160 continues to flow downstream 190 of the water valve 120. Figure 1As shown, the energy generation device 122 is located downstream 190 of the water valve 120 and within the pressurized water source 160, so that the water flow 162 applies a mechanical force to the energy generation device 122. The mechanical force applied by the water flow 162 can cause the energy generation device 122 to generate electricity 170 that charges the battery 118. As a non-limiting example, in one embodiment, the energy generation device 122 can include a turbine located downstream 190 of the water valve 120. When the water valve 120 is at least partially opened, as shown in the second example 102B, the water flow 162 from the pressurized water source 160 causes movement at the turbine (e.g., causes the turbine to rotate or turn). Based on the movement at the turbine, a generator associated with the energy generation device 122 can generate electricity 170 that charges the battery 118.

[0035] As another non-limiting example, in one embodiment, the energy generation device 122 can include a piezoelectric material (e.g., a piezoelectric crystal) located downstream 190 of the water valve 120. When the water valve 120 is at least partially opened, as shown in the second example 102B, the water flow 162 from the pressurized water source 160 applies mechanical pressure to the piezoelectric material. Based on the mechanical pressure applied to the piezoelectric material, the piezoelectric material generates electricity 170 that charges the battery 118.

[0036] It should be understood that the above embodiments are merely illustrative examples of energy generation devices 122 and should not be construed as limiting. In other embodiments, the energy generation device 122 can include other devices. As a non-limiting example, in another embodiment, the energy generation device 122 can include a piston paired with a generator, a Pelton wheel paired with a generator, a paddle wheel paired with a generator, etc.

[0037] Thus, as described above, opening the water valve 120 to apply mechanical pressure to the energy generating device 122 can be used to charge the battery 118. To ensure that the water valve 120 is opened at a frequency that facilitates adequate charging of the battery 118, the controller 114 can implement certain protocols.

[0038] According to one protocol, the controller 114 can at least partially open the water valve 120 based on a remaining battery life 133 associated with the battery 118. For illustration, the battery life monitor 132 can be configured to monitor the remaining battery life 133 associated with the battery 118. In response to determining that the remaining battery life 133 does not meet the threshold level, the battery life monitor 132 can send a signal to the water valve control unit 130 to alert the water valve control unit 130 that the remaining battery life 133 is low. As a non-limiting example, if the remaining battery life 133 drops below ten (10) percent, the battery life monitor 132 can send a signal to the water valve control unit 130 to alert the water valve control unit 130 that the remaining battery life 133 is low. Based on the signal, the water valve control unit 130 can generate a control signal 131 to at least partially open the water valve 120, and the mechanical pressure (from the water flow 162) applied to the energy generating device 122 in response to opening the water valve 120 can cause the energy generating device 122 to charge the battery 118.

[0039] According to another protocol, the controller 114 can at least partially open the water valve 120 based on the time 135 that has elapsed since the water valve 120 was last opened. To illustrate, the elapsed time monitor 134 can be configured to monitor the time 135 that has elapsed since the water valve 120 was at least partially opened. In response to determining that the elapsed time 135 exceeds the elapsed time limit, the elapsed time monitor 134 can send a signal to the water valve control unit 130 to alert the water valve control unit 130 that the water valve 120 has not been recently opened. As a non-limiting example, software integrated into the smart water valve device 110 can indicate that if the battery 118 is not charged, it is estimated that the battery 118 will completely lose battery life after three months. In this case, if the elapsed time monitor 134 determines that the time 135 that has elapsed since the water valve 120 was last opened exceeds seventy-five (75) days (e.g., approximately two and a half (2.5) months), the elapsed time monitor 134 can send a signal to the water valve control unit 130 to alert the water valve control unit 130 that the water valve 120 has not been recently opened. Based on this signal, the water valve control unit 130 can generate a control signal 131 to at least partially open the water valve 120, and the mechanical pressure (from the water flow 162) applied to the energy generating device 122 in response to opening the water valve 120 can enable the energy generating device 122 to charge the battery 118.

[0040] According to another protocol, the controller 114 can periodically open (or partially open) the water valve 120 to allow the energy generation device 122 to charge the battery 118. For illustration, the water valve control unit 130 can periodically generate a control signal 131 that at least partially opens the water valve 120. As non-limiting examples, the water valve control unit 130 can generate the control signal 131 daily, weekly, biweekly, monthly, bimonthly, etc.

[0041] about Figure 1 The described technology extends the life of the battery 118 by enabling the energy generation device 122 to charge the battery 118 each time the water valve 120 is at least partially opened, thereby extending the life of the smart water valve device 110. For example, by opening the water valve 120, the mechanical pressure associated with the water flow 162 is applied to the energy generation device 122 and causes the energy generation device 122 to generate electricity to charge the battery 118. Therefore, the battery 118 has a longer service life, thereby reducing the need for the user to replace the battery 118. In addition, as described below, by implementing this "self-charging" feature, the smart water valve device 110 can be installed in a location that is not close to an electrical outlet. For example, since the life of the battery 118 can be extended by using the smart water valve device 110 (e.g., by opening the water valve 120), an electrical outlet and a corresponding power cord are not required to power the smart water valve device 110.

[0042] As about Figure 2 and Figure 3 As described above, the smart water valve device 110 can also be used to detect a leak upstream 192 of the water valve 120 and provide a water flow 162 to the downstream smart water valve device in response to an indication of low battery power in the downstream smart water valve device. Figure 2 As described above, the leak detection unit 138 can determine whether there is a leak upstream 192 of the water valve 120. Figure 3 As described above, the downstream smart water valve device battery life monitor 140 can determine whether to open the water valve 120 to provide water flow 162 to the downstream smart water valve device.

[0043] Figure 2 is a schematic diagram of another example system 200 including a smart water valve device. For example, the system 200 includes Figure 1 The smart water valve device 110. Figure 2 In the third example 102C shown, the smart water valve device 110 is operating in a second state, wherein the water valve 120 is at least partially opened (or fully opened).

[0044] The smart water valve device 110 can be configured to regulate a water flow 262 from a pressurized water source 260. Similar to the pressurized water source 160, the pressurized water source 260 can correspond to a water pipe, a water tank, a water supply line, or any other source that generates water pressure. According to the third example 102C, the pressurized water source 260 includes a leak 290 located upstream 192 of the smart water valve device 110.

[0045] exist Figure 2 In the embodiment, the water valve 120 is at least partially opened, and the water flow 262 from the pressurized water source 260 passes through the smart water valve device 110 (e.g., through the water valve 120) and continues to flow downstream 190. Therefore, the water flow 262 applies a mechanical force to the energy generation device 122 downstream 190 of the water valve 120, and causes the energy generation device 122 to generate electricity 170 for charging the battery 118, which is similar to the case with the smart water valve device 110. Figure 1 However, due to the leak 290, the strength of the water flow 262 is reduced, and therefore the magnitude of the mechanical force applied to the energy generating device 122 is reduced. Therefore, the energy generating device 122 moves at a slower rate, thereby charging the battery 118 at a slower rate.

[0046] Due to the reduced charging rate based on the leak 290, the controller 114 can be configured to detect the presence of the leak 290 based on the charging rate of the battery 118. For example, the leak detection unit 138 can be configured to determine the battery charging rate 238 when the water valve 120 is at least partially opened. If the battery charging rate 238 does not meet a threshold (e.g., is below a threshold charging rate), the leak detection unit 138 can determine that there is a leak 290 upstream 192 of the water valve 120. As a non-limiting example, if there is no leak upstream of the water valve 120, the typical charging rate of the battery 118 can be four (4) amps per hour when the water valve 120 is fully opened. Assuming that the threshold for determining the presence of the leak 290 is seventy-five percent (75%) of the typical charging rate, if the leak detection unit 138 determines that the battery charging rate 238 when the water valve 120 is fully opened is less than three (3) amps per hour, the leak detection unit 138 can determine that there is a leak 290 upstream 192 of the water valve 120.

[0047] It should be understood that the above typical charging rates and charging rate thresholds are for illustration purposes only and should not be construed as limiting. In other embodiments, the typical charging rates and charging rate thresholds may vary.

[0048] Therefore, about Figure 2The described techniques enable the smart water valve device 110 to detect a leak 290 in the pressurized water source 260 based on the battery charging rate 238 when the water valve 120 is at least partially opened. Upon detecting the leak 290, the smart water valve device 110 can generate information and send the message (via the wireless transceiver 116) to the user to indicate the presence of the leak 290.

[0049] Figure 3 is a diagram of another example system 300 including a smart water valve device. For example, the system 300 includes Figure 1 The smart water valve device 110 and another smart water valve device 310 located 190 meters downstream of the smart water valve device 110. Figure 3 In the fourth example 102D shown, the smart water valve device 110 is operating in the first state, wherein the water valve 120 of the smart water valve device 110 is closed. Figure 3 In the fifth example 102E shown, the smart water valve device 110 is operating in the second state, wherein the water valve 120 is at least partially opened (or fully opened).

[0050] The smart water valve device 310 can have a similar configuration to the smart water valve device 110 and can operate in a substantially similar manner. For example, the smart water valve device 310 can include a memory (not shown), a wireless transceiver 316, a battery 318, a water valve (not shown), a controller (not shown), and an energy generation device 322. In a similar manner as described with respect to the smart water valve device 110, the energy generation device 322 associated with the smart water valve device 310 can charge the battery 318 of the smart water valve device 310 based on the water flow 362. However, since the smart water valve device 310 is located downstream 190 of the smart water valve device 110, the water flow 362 from the pressurized water source 360 ​​cannot reach the smart water valve device 310 unless the water valve 120 of the smart water valve device 110 is at least partially opened. Therefore, in order to ensure that the water flow 362 is available for the smart water valve device 310 to charge the battery 318, the smart water valve device 110 must at least partially open the water valve 120.

[0051] In order to determine whether the water valve 120 needs to be opened to allow the water flow 362 to reach the smart water valve device 310 to charge the battery 318, the smart water valve device 110 can monitor the remaining battery life 333 associated with the battery 318 of the smart water valve device 310. For illustration, in a manner similar to the battery life monitor 132 of the smart water valve device 110, the smart water valve device 310 can include a battery life monitor (not shown) that monitors the remaining battery life 333 of the battery 318. Using the wireless transceiver 316, the smart water valve device 310 can send an indication of the remaining battery life 333 to the smart water valve device 110 via a wireless network. The wireless transceiver 116 of the smart water valve device 110 can receive the indication from the smart water valve device 310, and the downstream smart water valve device battery life monitor 140 can monitor the remaining battery life 333 associated with the battery 318 based on the indication.

[0052] In response to determining that the remaining battery life 333 associated with the battery 318 does not meet the threshold level, the downstream smart water valve device battery life monitor 140 can send a signal to the water valve control unit 130 to alert the water valve control unit 130 that the remaining battery life 333 is low. As a non-limiting example, if the remaining battery life 333 is less than ten (10) percent, the downstream smart water valve device battery life monitor 140 can send a signal to the water valve control unit 130 to alert the water valve control unit 130 that the remaining battery life 333 is low. Based on the signal, the water valve control unit 130 can generate a control signal 131 that at least partially opens the water valve 120, and the water flow 362 can travel downstream 190 to the smart water valve device 310, as shown in the fifth example 102E.

[0053] Once the water flow 362 travels downstream 190 to the smart water valve device 310, the smart water valve device 310 can at least partially open the internal water valve to enable the water flow 362 to apply mechanical force to the energy generation device 322. The mechanical force applied by the water flow 362 can enable the energy generation device 322 to generate electricity 370 that charges the battery 318.

[0054] Therefore, about Figure 3 The described techniques enable the smart water valve device 110 to monitor the remaining battery life 333 associated with the battery 318 of the smart water valve device 310. Based on the remaining battery life 333, the smart water valve device 110 can at least partially open the water valve 120 to ensure that the water flow 362 is available for the smart water valve device 310 to charge the battery 318.

[0065] IV. Example water supply system using smart water valve device

[0066] Figure 5 A water supply system 500 using a smart water valve device is depicted. For example, Figure 5 , the water supply system 500 includes a pressurized water source 560 coupled to a building 550 and to a pair of smart water valve devices 110A, 110B. The pressurized water source 560 can correspond to an external or underground water supply line that directs water flow 562 to different sprinklers 530 via the smart water valve device 110. For example, the pressurized water source 560 can direct water flow 562 from the building 550 to the sprinklers 530A, 530B via the smart water valve device 110A, and the pressurized water source 560 can direct water flow 562 from the building 550 to the sprinklers 530C, 530D via the smart water valve device 110B.

[0067] exist Figure 5530B, sprinklers 530A, 530B are activated and sprinklers 530C, 530D are deactivated. To activate sprinklers 530A, 530B, smart water valve device 110A at least partially opens the internal water valve to allow water flow 562 to flow downstream from building 550 to sprinklers 530A, 530B. In some cases, sprinklers 530A, 530B are activated in response to smart water valve device 110A wirelessly receiving a data packet including a command to at least partially open the internal water valve. In other cases, sprinklers 530A, 530B are activated in response to smart water valve device 110A periodically opening the internal water valve, opening the internal water valve in response to a low battery life determination, opening the internal water valve in response to an elapsed time exceeding an elapsed time threshold, etc.

[0068] When the sprinklers 530A, 530B are activated, the water flow 562 applies a mechanical force to the energy generation device 122A downstream of the internal water valve of the smart water valve device 110A. The mechanical force applied by the water flow 562 enables the energy generation device 122A to generate electricity 170A that charges the battery of the smart water valve device 110A.

[0069] Since the internal water valve of the smart water valve device 110B is closed, the water flow 562 cannot flow downstream of the water valve to apply mechanical force to the energy generation device 122B. Therefore, in order to charge the battery of the smart water valve device 110B, the smart water valve device 110B can at least partially open the internal water valve to allow the water flow 562 to apply mechanical force to the energy generation device 122B.

[0070] about Figure 5 The described technology enables the installation of the smart water valve devices 110A, 110B without laying power lines through the ground. For example, since the battery life of the smart water valve devices 110A, 110B can be extended each time the internal water valve of the smart water valve device 110A, 110B is opened to activate the associated sprinkler 530, no power outlet and corresponding power lines are required to power the smart water valve devices 110A, 110B. Therefore, higher installation flexibility can be achieved.

[0071] Figure 6 A water supply system 600 using a smart water valve device is depicted. For example, Figure 6 , water supply system 600 includes a pressurized water source 660 coupled to building 650 and to smart water valve device 110C. Pressurized water source 660 can correspond to an external or underground water supply line that directs water flow 662 to sprinklers 630A, 630B via smart water valve device 110C.

[0072] exist Figure 6630B are activated. To activate the sprinklers 630A, 630B, the smart water valve device 110C at least partially opens the internal water valve to allow water flow 662 to flow downstream from the building 650 to the sprinklers 630A, 630B. In some cases, the sprinklers 630A, 630B are activated in response to the smart water valve device 110C wirelessly receiving a data packet including a command to at least partially open the internal water valve.

[0073] When the sprinklers 630A, 630B are activated, the water flow 662 applies a mechanical force to the energy generation device 122C downstream of the internal water valve of the smart water valve device 110C. The mechanical force applied by the water flow 662 enables the energy generation device 122C to generate electricity 170C that charges the battery of the smart water valve device 110C.

[0074] Additionally, the electrical power 170C can be directed to power emergency lights 690 and / or to power alarm systems 692. For example, in one embodiment, when the water flow 662 from the pressurized water source 660 applies a mechanical force to the energy generation device 122C, the electrical power 170C generated by the energy generation device 122C can power the emergency lights 690. As another example, in one embodiment, when the water flow 662 from the pressurized water source 660 applies a mechanical force to the energy generation device 122C, the electrical power 170C generated by the energy generation device 122C can power the alarm system 692.

[0075] V. Example Method

[0076] Figure 7 is a flow chart illustrating an example method 700. The method 700 can be performed by a smart water valve device (eg, the smart water valve device 110).

[0077] The method 700 includes operating a water valve by a controller to regulate water flow from a pressurized water source at block 702. The water valve and the controller are included in a smart water valve device. For example, referring to Figure 1 , the controller 114 is capable of operating the water valve 120 to regulate a water flow 162 from a pressurized water source 160 . The water valve 120 and the controller 114 are included in the smart water valve device 110 .

[0078] The method 700 also includes charging the battery based on the water flow from the pressurized water source by the energy generation device at block 704. The battery is configured to power the controller, and the energy generation device is associated with the smart water valve device. For example, referring to Figure 1 The energy generation device 122 is capable of charging the battery 118 based on the water flow 162 from the pressurized water source 160 . The battery 118 is configured to power the controller 114 , and the energy generation device 122 is associated with the smart water valve device 110 .

[0079] In one embodiment of the method 700, the energy generation device 122 is included in the smart water valve device 110 and is located downstream 190 of the water valve 120. In another embodiment of the method 700, the energy generation device 122 is located outside the smart water valve device 110 and is located downstream 190 of the water valve 120. The energy generation device 122 can be located within the pressurized water source 160 so that mechanical force from the water flow 162 can be applied to the energy generation device 122.

[0080] According to one embodiment of the method 700, the energy generation device 122 includes a turbine located downstream 190 of the water valve 120. When the water valve 120 is at least partially opened, the flow of water 162 from the pressurized water source 160 causes motion at the turbine. The energy generation device can also include a generator configured to generate electricity 170 to charge the battery 118 based on the motion at the turbine.

[0081] According to one embodiment of the method 700, the energy generation device 122 includes a piezoelectric material located downstream 190 of the water valve 120. When the water valve 120 is at least partially opened, the water flow 162 from the pressurized water source 160 applies mechanical pressure to the piezoelectric material, and the piezoelectric material is configured to generate electricity 170 to charge the battery 118 based on the mechanical pressure.

[0082] According to one embodiment, the method 700 includes generating, by the controller 114, a control signal 131 that at least partially opens the water valve 120. In one embodiment, the method 700 includes monitoring, by the controller 114, a wireless data communication channel for at least one data packet, the at least one data packet including a command to at least partially open the water valve 120. The control signal 131 can be generated in response to detecting the at least one data packet. In another embodiment, the method 700 includes monitoring, by the controller 114, a remaining battery life 133 associated with the battery 118. The control signal can be generated in response to the remaining battery life 133 not meeting a threshold level. In another embodiment, the method 700 includes monitoring, by the controller 114, a time 135 that has passed since the water valve 120 was at least partially opened. The control signal can be generated in response to the elapsed time 135 exceeding an elapsed time limit. In yet another embodiment, the control signal 131 can be generated periodically.

[0083] According to one embodiment, the method 700 includes determining whether the leak 290 is present upstream 192 of the water valve 120 based on a charge rate of the battery 118 (eg, based on the battery charge rate 238 ) when the water valve 120 is at least partially open.

[0084] According to one embodiment, method 700 includes powering emergency light 690 by energy generation device 122 based on water flow 662 from pressurized water source 660. According to one embodiment, method 700 includes powering alarm system 692 by energy generation device 122 based on water flow 662 from pressurized water source 660.

[0085] According to one embodiment, the method 700 includes monitoring, by the controller 114, a remaining battery life 333 associated with a second battery 318, the second battery 318 being associated with a second smart water valve device 310 located downstream 190 of the smart water valve device 110. The method 700 also includes generating a control signal 131 to at least partially open the water valve 120 in response to determining that the remaining battery life 333 associated with the second battery 118 does not meet a threshold level. In response to at least partially opening the water valve 120, a water flow 362 from the pressurized water source 360 ​​travels downstream 190 to the second smart water valve device 310.

[0086] Figure 7 The method 700 extends the life of the battery 118 by enabling the energy generation device 122 to charge the battery 118 each time the water valve 120 is at least partially opened, thereby extending the life of the smart water valve device 110. For example, by opening the water valve 120, the mechanical pressure associated with the water flow 162 is applied to the energy generation device 122, and the energy generation device 122 generates electricity 170 to charge the battery 118. Therefore, the battery 118 has a longer service life, thereby reducing the need for the user to replace the battery 118. In addition, as described below, by implementing this "self-charging" feature, the smart water valve device 110 can be installed in a location that is not close to an electrical outlet. For example, since the life of the battery 118 can be extended by using the smart water valve device 110 (e.g., by opening the water valve 120), a power outlet and a corresponding power cord are not required to power the smart water valve device 110.

[0087] Figure 8 is a flow chart illustrating another example method 800. The method 800 can be performed by a smart water valve device (eg, the smart water valve device 110).

[0088] According to method 800, at block 802, the smart water valve device monitors a wireless communication channel to obtain a command to open a water valve. Figure 1 , the wireless data communication channel monitor 136 monitors the wireless communication channel (associated with the wireless transceiver 116 ) for a command to open the water valve 120 .

[0089] At decision block 804, the smart water valve device determines whether a command to open the water valve is detected. Figure 1, the wireless data communication channel monitor 136 determines whether the wireless transceiver 116 detects (e.g., receives) a command to open the water valve 120. If a command to open the water valve is detected at decision block 804, the method 800 proceeds to block 814. If a command to open the water valve is not detected at decision block 804, the method 800 proceeds to block 806.

[0090] At block 806, the smart water valve device monitors the remaining battery life of a battery associated with the smart water valve device. Figure 1 , the battery life monitor 132 monitors the remaining battery life 133 of the battery 118 that powers the controller 114 (eg, powers the smart water valve device 110 ).

[0091] At decision block 808, the smart water valve device determines whether the remaining battery life of the battery is less than a threshold level. Figure 1 , the battery life monitor 132 determines whether the remaining battery life 133 of the battery 118 is less than a threshold level. If the remaining battery life of the battery is less than the threshold level at decision block 808, the method 800 proceeds to block 814. If the remaining battery life of the battery is not less than the threshold level at decision block 808, the method 800 proceeds to block 810.

[0092] At block 810, the smart water valve device monitors the time that has passed since the water valve was last opened. Figure 1 , the elapsed time monitor 134 monitors the time 135 that has elapsed since the water valve 120 was last opened.

[0093] At decision block 812, the smart water valve device determines whether the elapsed time exceeds the elapsed time limit. Figure 1 , the elapsed time monitor 134 determines whether the elapsed time 135 exceeds the elapsed time limit. If the elapsed time exceeds the elapsed time limit at decision block 812, the method 800 proceeds to block 814. If the elapsed time does not exceed the elapsed time limit, the method 800 returns to block 802.

[0094] At block 814, the smart water valve device opens the water valve. Figure 1 , the water valve control unit 130 generates a control signal 131 to at least partially open the water valve 120 .

[0095] At block 816, the energy generation device generates electricity based on the water flow to charge the battery of the smart water valve device. Figure 1 , the water flow 162 applies a mechanical force to the energy generation device 122 in response to the opening of the water valve 120. Based on the mechanical force, the energy generation device 122 generates electricity 170 to charge the battery 118.

[0096] At block 818, the smart water valve device closes the water valve and the method 800 returns to block 802. Figure 1 , the water valve control unit 130 generates a signal to close the water valve 120.

[0097] Figure 8 The method 800 in the embodiment of the present invention prolongs the life of the battery 118 by enabling the energy generation device 122 to charge the battery 118 each time the water valve 120 is at least partially opened, thereby extending the life of the smart water valve device 110. For example, by opening the water valve 120, the mechanical pressure associated with the water flow 162 is applied to the energy generation device 122, and the energy generation device 122 generates electricity 170 to charge the battery 118. Therefore, the battery 118 has a longer service life, thereby reducing the need for the user to replace the battery 118. In addition, as described below, by implementing this "self-charging" feature, the smart water valve device 110 can be installed in a location that is not close to an electrical outlet. For example, since the life of the battery 118 can be extended by using the smart water valve device 110 (e.g., by opening the water valve 120), an electrical outlet and a corresponding power cord are not required to power the smart water valve device 110.

[0098] Fig. 9 is a flow chart illustrating another example method 900. The method 900 can be performed by a smart water valve device (eg, the smart water valve device 110).

[0099] At block 902, the smart water valve device opens the water valve. Figure 1 , the water valve control unit 130 generates a control signal 131 to at least partially open the water valve 120 .

[0100] At block 904, the energy generation device generates electricity based on the water flow to charge the battery of the smart water valve device. Figure 1 , the water flow 162 applies a mechanical force to the energy generation device 122 in response to the opening of the water valve 120. Based on the mechanical force, the energy generation device 122 generates electricity 170 to charge the battery 118.

[0101] At block 906, the smart water valve device monitors the charging rate of the battery. Figure 2 , the leak detection unit 138 monitors the battery charging rate 238 of the battery 118 when the water valve 120 is at least partially opened.

[0102] At decision block 908, the smart water valve device determines whether the charging rate is less than a threshold charging rate. Figure 2, the leakage detection unit 138 determines whether the battery charging rate 238 is less than the threshold charging rate. If the charging rate is not less than the threshold charging rate at decision block 908, the method 900 proceeds to block 910. At block 910, the smart water valve device determines that there is no leak upstream of the water valve.

[0103] If the charging rate is less than the threshold charging rate at decision block 908, the method 900 proceeds to block 912. At block 912, the smart water valve device determines that there is a leak upstream of the water valve. Figure 2 , the leak detection unit 138 determines that a leak 290 exists upstream 192 of the water valve 120. At block 914, the smart water valve device generates a message indicating the leak. For example, referring to Figure 2 Upon detecting a leak 290 , the smart water valve device 110 generates and sends a message to a user (via the wireless transceiver 116 ) to indicate the presence of a leak 290 .

[0104] therefore, Fig. 9 The method 900 enables the smart water valve device 110 to detect a leak 290 in the pressurized water source 260 based on the battery charging rate 238 when the water valve 120 is at least partially opened.
