Description

Technical Field

[0001] The present invention relates to the technical field of drainage control, and in particular to a method and device for controlling accumulated water drainage, and a computer-readable medium. Background Art

[0002] Newer residential homes with basements often have one or more built-in sump pits to collect water that accumulates around the foundation. A sump pump is often installed in the sump pit to remove the accumulated water. This sump pump is typically powered by the home's electrical system via utility power. When powered by utility power, the drainage system can remove the water promptly, preventing the accumulation of water and the resulting overflow.

[0003] However, electric-controlled drainage systems powered by mains electricity cannot operate during a mains power outage. This prevents the drainage of accumulated water, causing it to rise further and potentially overflow. Therefore, existing drainage devices incorporate a backup battery that can be used to power the sewage pump during a power outage. However, existing solutions that utilize a backup battery to power sewage pumps typically switch to inverter operation after a mains power outage, keeping the inverter (which converts the DC battery into AC power for the load) powered on to facilitate subsequent drainage control. This control method fails to tailor battery power to the actual battery state, potentially damaging the device and the load (the sewage pump). For example, forcing the battery-powered inverter to operate when the battery is overvoltage can damage the inverter. Powering the load (the sewage pump) when the battery is undervoltage can damage the load and reduce its service life. Furthermore, the inverter consumes significant power when unloaded, significantly draining the battery and reducing the standby time of the power supply control device. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a method, device, and computer-readable medium for controlling accumulated water drainage. The method is applied to a drainage control device, which switches between mains power supply and battery inverter power supply to drive the drainage device to start drainage. The method comprises the following steps:

[0005] Predefine multiple threshold intervals for battery voltage, where each threshold interval corresponds to a different battery state;

[0006] Obtain the presence of mains input data and water level data, and periodically obtain battery voltage data;

[0007] Battery status judgment:

[0008] Get the battery voltage data of the current cycle;

[0009] Recall the predefined battery voltage multi-level threshold interval and the stored battery status of the previous cycle;

[0010] According to the threshold range that the battery voltage value of the current cycle falls into, the battery status of the current cycle is confirmed.

[0011] Alternatively, based on the threshold interval within which the battery voltage value of the current cycle falls, and when the battery state of the previous cycle meets the target battery state, the battery state of the current cycle is confirmed and the battery state of the current cycle is stored;

[0012] Drainage power supply output control:

[0013] When it is determined based on the water level data that drainage is required and there is mains power input, the mains power supply is turned on to drive the drainage device, and the battery status of the current cycle is used to determine whether to charge the battery;

[0014] When it is determined according to the water level data that drainage is required and there is no mains input, if the battery status of the current cycle meets the preset output battery status, the battery inverter power supply is turned on to drive the drainage device, otherwise, the battery inverter power supply is turned off.

[0015] Preferably, the multi-level threshold intervals include at least a severe undervoltage interval, an undervoltage interval, a low voltage interval, a recovery voltage interval, a normal voltage interval, and an overvoltage interval, and the corresponding battery states are a severe undervoltage state, an undervoltage state, a low voltage state, a recovery voltage state, a normal voltage state, and an overvoltage state, respectively. The confirmation condition set for each battery state is as follows:

[0016] Severe undervoltage state: the battery voltage value of the current cycle is less than the first set voltage value;

[0017] Undervoltage state: The first set voltage value < the battery voltage value of the current cycle < the second set voltage value, and the battery state in the previous cycle was not in a serious undervoltage state;

[0018] Low voltage state: The second set voltage value < the battery voltage value of the current cycle < the third set voltage value, and the battery state in the previous cycle was not undervoltage state or severe undervoltage state;

[0019] Recovering voltage status: the battery voltage value of the current cycle is greater than the fourth set voltage value, and the battery status of the previous cycle is one of low voltage state, undervoltage state or severe undervoltage state;

[0020] Normal voltage state: the third set voltage value < the battery voltage value of the current cycle < the fifth set voltage value, and the battery state in the previous cycle was one of the overvoltage state and the recovery voltage state;

[0021] Overvoltage state: the battery voltage value of the current cycle is greater than the fifth set voltage value;

[0022] If the battery voltage value of the current cycle is equal to the critical value or does not meet the above battery status condition set, the current battery status is the battery status of the previous cycle;

[0023] Among them, the first set voltage value<the second set voltage value<the third set voltage value<the fourth set voltage value<the fifth set voltage value.

[0024] Preferably, in the drainage power supply output control, the preset outputtable battery states are low voltage state and normal voltage state.

[0025] Preferably, the drainage power supply output control further includes:

[0026] When the battery is in a severely undervoltage state, the system will enter the battery sleep mode. When in sleep mode, the system will wake up and detect the battery voltage and AC input according to the set wake-up cycle.

[0027] Preferably, in the drainage power supply output control, the method for determining whether drainage is required based on water level data is as follows:

[0028] Water level detection:

[0029] Two water level sensors are set in the area where drainage is required, with a height difference between the water level sensors; the water level sensor at the higher position is the high water level sensor, and the other one is the low water level sensor;

[0030] When the low water level sensor does not detect water and the high water level sensor does not detect water, the current water level is determined to be a low water level;

[0031] When the low water level sensor detects water and the high water level sensor does not detect water, the current water level is determined to be a medium water level;

[0032] When the low water level sensor detects water and the high water level sensor detects water, the current water level is determined to be a high water level;

[0033] When the water level detection result is high, it is determined that drainage is necessary and a drainage output request is triggered;

[0034] When the water level detection result is a low water level, it is determined that drainage is not necessary, and a stop drainage output request is triggered.

[0035] Preferably, the water level detection further includes:

[0036] When the low water level sensor does not detect water and the high water level sensor detects water, it is judged as a sensor error.

[0037] Preferably, the drainage control device is further provided with a normally open mode and a normally closed mode;

[0038] In the normally open mode, the drainage power supply output control stage will always send the drainage output demand;

[0039] In the normally closed mode, the drainage power supply output control stage will always close the drainage output demand.

[0040] The present invention further provides a water accumulation drainage control device, which adopts any of the above-mentioned water accumulation drainage control methods, including:

[0041] a storage unit, configured to store predefined battery voltage multi-level threshold intervals and battery states, wherein each threshold interval corresponds to a different battery state;

[0048] According to the threshold range that the battery voltage value of the current cycle falls into, the battery status of the current cycle is confirmed.

[0049] Alternatively, based on the threshold interval within which the battery voltage value of the current cycle falls, and when the battery state of the previous cycle meets the target battery state, the battery state of the current cycle is confirmed; the confirmed battery state of the current cycle is stored in a storage unit; and the control execution module is used to:

[0050] When it is determined that drainage is required based on the water level data obtained by the water level detection module and the mains power detection module indicates that mains power is input, the mains power supply is turned on to drive the drainage device, and the battery status of the current cycle obtained by the battery status judgment module is used to determine whether the battery should be charged;

[0051] When it is determined that drainage is required based on the water level data obtained by the water level detection module and the AC power detection module indicates that there is no AC power input, if the battery status of the current cycle obtained by the battery status judgment module meets the preset output battery status, the battery inverter power supply is turned on to drive the drainage device; otherwise, the battery inverter power supply is turned off.

[0052] The present invention also provides a computer-readable medium having a computer program stored thereon, wherein when the computer program is executed by a processor, any of the above-described methods for controlling accumulated water and drainage is implemented.

[0053] The water drainage control method provided by the present invention significantly improves the safety of the device during use by combining multi-level battery voltage detection with a specific output control method. It also avoids the phenomenon of repeated and rapid switching between multiple battery states during battery status detection, which can cause device abnormalities. Furthermore, the water drainage control method provided by the present invention activates the inverter function only when battery power is supplied and drainage is required, significantly reducing the device's standby power consumption. Under the condition of a power outage with the same battery capacity, the device using the present invention can significantly extend its standby time.

[0065] like Figure 1 As shown, an embodiment of the present invention provides a method, device, and computer-readable medium for controlling accumulated water drainage. The method is applied to a drainage control device, which switches between mains power supply and battery inverter power supply to drive the drainage device to start drainage. The method steps include:

[0066] Predefine multiple threshold intervals for battery voltage, where each threshold interval corresponds to a different battery state;

[0067] Obtain the presence of mains input data and water level data, and periodically obtain battery voltage data;

[0068] Battery status judgment:

[0069] Get the battery voltage data of the current cycle;

[0070] Recall the predefined battery voltage multi-level threshold interval and the stored battery status of the previous cycle;

[0071] According to the threshold range that the battery voltage value of the current cycle falls into, the battery status of the current cycle is confirmed.

[0072] Alternatively, based on the threshold interval within which the battery voltage value of the current cycle falls, and when the battery state of the previous cycle meets the target battery state, the battery state of the current cycle is confirmed and the battery state of the current cycle is stored;

[0073] Drainage power supply output control:

[0074] When it is determined based on the water level data that drainage is required and there is mains power input, the mains power supply is turned on to drive the drainage device, and the battery status of the current cycle is used to determine whether to charge the battery;

[0075] When it is determined according to the water level data that drainage is required and there is no mains input, if the battery status of the current cycle meets the preset output battery status, the battery inverter power supply is turned on to drive the drainage device, otherwise, the battery inverter power supply is turned off.

[0076] In specific implementation, the drainage control device is provided with a normally open mode, a normally closed mode and an automatic mode.

[0077] When the drainage control device is turned on, it will first read the operating status stored in the FLASH when it was last turned off, and use it as the initial operating status when it is turned on this time. Figure 2 The user can switch between the three modes of automatic, normally open, and normally closed by pressing the button. Under normal circumstances (normal battery voltage and normal equipment), when the user uses the automatic mode: the drainage control device will control the power supply drainage device (water pump) according to the water level data, the presence of mains input and the battery voltage data;

[0078] In the normally open mode: switch the inverter or mains power supply according to the mains power status to ensure the normal power supply of the drainage device;

[0079] In the normally closed mode: all power supply to the drainage device will be cut off, which is used for users to shut down the device when conducting inspections to ensure safety during inspections.

[0080] In automatic mode:

[0081] predefined multiple battery voltage threshold intervals, where each threshold interval corresponds to a different battery state, wherein the multiple threshold intervals include at least a severe undervoltage interval, an undervoltage interval, a low voltage interval, a recovery voltage interval, a normal voltage interval, and an overvoltage interval, and the corresponding battery states are severe undervoltage, undervoltage, low voltage, recovery voltage, normal voltage, and overvoltage, respectively;

[0082] Obtain the presence of mains input data and water level data, and periodically obtain battery voltage data. The battery voltage detection period (1S ≤ detection period ≤ 3S) can be set according to actual conditions, including but not limited to setting it to 1S. If the detected battery voltage value within the detection period is greater than a certain battery voltage threshold range, the current battery status is determined to be the battery status represented by the threshold range. For example, if the detected battery voltage value is greater than 15V for 1 consecutive second, the current battery status is determined to be overvoltage. By setting the detection period, the judgment is prevented from being affected by battery voltage fluctuations or sampling distortion, thereby improving the accuracy of battery voltage detection;

[0083] Current battery status judgment (such as Figure 3 shown):

[0084] Get the battery voltage data of the current cycle;

[0085] Recall the predefined battery voltage multi-level threshold interval and the stored battery status of the previous cycle;

[0086] According to the threshold range that the battery voltage value of the current cycle falls into, the battery status of the current cycle is confirmed.

[0087] Alternatively, based on the threshold interval within which the battery voltage value of the current cycle falls, and when the battery status of the previous cycle meets the target battery status, the battery status of the current cycle is confirmed and stored. Specifically, the confirmation of each battery status needs to meet the following set of conditions to be valid:

[0088] Severe undervoltage state: the battery voltage value of the current cycle is less than the first set voltage value;

[0089] Undervoltage state: The first set voltage value < the battery voltage value of the current cycle < the second set voltage value, and the battery state in the previous cycle was not in a serious undervoltage state;

[0090] Low voltage state: The second set voltage value < the battery voltage value of the current cycle < the third set voltage value, and the battery state in the previous cycle was not undervoltage state or severe undervoltage state;

[0091] Recovering voltage status: the battery voltage value of the current cycle is greater than the fourth set voltage value, and the battery status of the previous cycle is one of low voltage state, undervoltage state or severe undervoltage state;

[0092] Normal voltage state: the third set voltage value < the battery voltage value of the current cycle < the fifth set voltage value, and the battery state in the previous cycle was one of the overvoltage state and the recovery voltage state;

[0093] Overvoltage state: the battery voltage value of the current cycle is greater than the fifth set voltage value;

[0094] Among them, the first set voltage value < the second set voltage value < the third set voltage value < the fourth set voltage value < the fifth set voltage value. The specific values ​​of the first set voltage value, the second set voltage value, the third set voltage value, the fourth set voltage value, and the fifth set voltage value can be set according to the actual battery used. For example, the first set voltage value is 10V; the second set voltage value is 10.4V; the third set voltage value is 11.4V; the fourth set voltage value is 12.4V; and the fifth set voltage value is 15V, but it is not limited to this.

[0095] The above-mentioned battery must meet the above-mentioned conditions to enter a certain state. When the battery sampling voltage in a certain sampling cycle is equal to a certain critical value or does not meet any of the above-mentioned battery state condition sets, the current battery state will inherit the battery state of the previous cycle, thereby avoiding the situation where the battery state is unclear.

[0096] The conditional setting of the battery status of the previous cycle provided in this embodiment is intended to prevent the battery status from repeatedly switching between two or more states. The condition set aggregates multiple judgment conditions together, and the lack of a condition can cause anomalies in some cases. For example, since the battery voltage fluctuates when the battery is loaded and unloaded (the battery voltage may drop by about 1-2V), if the battery status of the current cycle is low voltage when the control device is unloaded (i.e., the water pump is not supplying power to the load), the battery voltage drops after the device is loaded. The battery voltage meets the voltage setting conditions for the undervoltage state and also meets the condition set for the undervoltage battery state, and the battery status switches to the battery undervoltage state. At this time, the control device will shut down the power output, and the battery voltage will rebound. The rebounded voltage meets the battery voltage judgment conditions for the low voltage state, but the battery status of the previous cycle does not meet the conditions, which can prevent the battery status from switching to the low voltage state again. Therefore, although the voltage after rebound does not meet the judgment conditions for the undervoltage state, it cannot switch to other states. The battery status at this time will remain in the undervoltage state, which can prevent the battery status from switching repeatedly and rapidly, thereby avoiding abnormal on and off phenomena of the load (water pump).

[0097] Drainage power supply output control (such as Figure 5 shown):

[0098] When drainage is required based on the water level data, output control is performed based on the battery voltage status confirmed above. The control conditions are as follows:

[0099] When the battery is severely undervoltage, the system checks whether there is AC power. If there is AC power, the inverter output is turned off, the AC output is turned on, the battery AC charging input is turned on, and the buzzer is turned off. If there is no AC power, the inverter output, the AC output, the battery AC charging input, and the buzzer are turned off, and a battery sleep request is generated. In this step, when the battery is severely undervoltage, the battery health is already very poor. At this time, the alarm is turned off and the device enters low power mode (equivalent to the shutdown state) to reduce the battery power output, reduce battery power consumption, and ensure battery health as much as possible.

[0100] When the battery is in an undervoltage state, it determines whether there is mains power. If there is mains power, the inverter output is turned off, the mains output is turned on, the battery mains charging input is turned on, and the buzzer is turned off. If there is no mains power, the inverter output, the mains output, the battery mains charging input are turned off, and the buzzer is turned on.

[0101] When the battery is in a low voltage state: determine whether there is AC power. If there is AC power, turn off the inverter output, turn on the AC output, turn on the battery AC charging input, and turn off the buzzer; if there is no AC power, turn on the inverter output, turn off the AC output, turn off the battery AC charging input, and turn on the buzzer. Since the low voltage state has not reached the undervoltage state, it can output normally with load, and the low voltage output will not have much impact on the health of the battery.

[0102] When the battery is in the recovery voltage state, no control is performed. The recovery voltage state is a transition state in which the battery transitions from low voltage, undervoltage, or severe undervoltage to normal voltage. No output control is performed in this stage.

[0103] When the battery is in a normal voltage state, it determines whether there is mains power. If there is mains power, the inverter output is turned off, the mains output is turned on, the battery mains charging input is turned on, and the buzzer is turned off. If there is no mains power, the inverter output is turned on, the mains output is turned off, the battery mains charging input is turned off, and the buzzer is turned off.

[0104] In an overvoltage state, the inverter output, mains output, battery mains charging input, and buzzer are turned on. Enabling the inverter when the battery is overvoltage may damage the inverter. Furthermore, in the event of battery overvoltage, undervoltage, or severe undervoltage, the device will ignore output requests. Even if the mains power is off, the device will not supply power to the load. This prioritizes device and battery safety over operational priorities, ensuring device and battery safety and reducing or preventing safety incidents.

[0105] The above-mentioned inverter output refers to inverting the DC voltage of the battery into AC power that can power the drainage device (water pump). This is an existing technology in the art and will not be described in detail here.

[0106] In the above output control, the primary purpose of multi-level voltage status detection is to ensure equipment safety, as follows:

[0107] a. Forcibly turning on the inverter when the battery is over-voltage may cause irreversible damage to the inverter.

[0108] b. When the battery is undervoltage, if it still outputs normally, a high-power load such as a water pump will damage the battery.

[0109] c. When the battery is severely undervoltage, the battery condition is very poor. The MCU is controlled to enter low power mode and turn off the output to minimize the battery output to prevent complete damage to the battery.

[0110] In addition, in the control method provided in this embodiment, the battery inverter is turned on only when drainage is required. If drainage is not required at present, the inverter is disconnected. Especially in the case of a city power outage, this control method can avoid the no-load consumption of the inverter, thereby greatly extending the standby time of the control device.

[0111] The water accumulation drainage control method provided by the embodiment of the present invention, through the above-mentioned multi-level voltage detection, refines the granularity of output control, improves the protection of equipment, inverters, batteries, etc., and enhances safety performance. By combining multi-level voltage detection with the battery status of the previous cycle to determine the battery status of the current cycle, it can avoid the problem of repeated and rapid switching between multiple states when the battery voltage fluctuates, which may cause some abnormal behavior of the equipment.

[0112] In addition, most related products on the market switch to inverter operation after a power outage. In the embodiments of the present invention, the inverter function is activated only when the battery is powered and drainage is required, which can significantly reduce the standby power consumption of the device. Under the condition of the same battery capacity and the mains power outage, the control method of the embodiment of the present invention can significantly extend the standby time of the control device.

[0113] The operating logic of the above low power mode is as follows:

[0114] like Figure 6As shown, when the battery is severely undervoltage (battery voltage <10V) and there is no mains input, the device enters low-power mode, shutting down all outputs to reduce energy loss. The device wakes up every set wake-up period (set according to actual conditions) to check the battery voltage and mains input. Low-power mode is exited only when mains input is present or the battery voltage exceeds 12.4V (i.e., the battery voltage meets the voltage recovery criteria). The wake-up period can be set to 8 seconds, and this wake-up is achieved through the MCU's watchdog module (this is prior art and will not be further described here). During normal operation, the MCU in the control module maintains a maximum watchdog timer of 64ms. If the MCU does not clear the watchdog timer within 64ms, it will reset and restart to prevent unexpected freezes. Before entering low-power mode, the watchdog timer is set to 8 seconds. If the watchdog timer is not cleared within 8 seconds during low-power mode, the MCU will wake up and resume normal operation. After waking up, the MCU will check the mains input and battery voltage. If the device still does not meet operating conditions, it will enter low-power mode again. In this step, when the battery is severely undervoltage, the battery health status is already very poor. At this time, turning off the alarm and entering low-power mode is to reduce the battery power output, reduce battery power consumption, and ensure battery health as much as possible. In this step, the wake-up period is set to 6S-9S. On the one hand, it avoids the problem of the MCU being frequently woken up due to the wake-up time being set too short, because each wake-up will increase power consumption in a short period of time, which will increase battery power consumption. On the other hand, it avoids setting the wake-up time too long. When the external conditions meet the operating conditions, the delay in the MCU being awakened and working normally will be very long, affecting the user experience.

[0115] When implementing it specifically, Figure 4 In the drainage power supply output control, the method for judging whether drainage is required based on water level data is as follows:

[0116] Water level detection:

[0117] Two water level sensors are set in the area where drainage is required, with a height difference between the water level sensors; the water level sensor at the higher position is the high water level sensor, and the other one is the low water level sensor. The height position of the high water level sensor is the "liquid level height at which drainage is desired to be started" set by the user, and the height position of the low water level sensor is the "liquid level height at which the pump is desired to be stopped" set by the user.

[0118] When the low water level sensor does not detect water and the high water level sensor does not detect water, the current water level is determined to be a low water level;

[0119] When the low water level sensor detects water and the high water level sensor does not detect water, the current water level is determined to be a medium water level;

[0120] When the low water level sensor detects water and the high water level sensor detects water, the current water level is determined to be a high water level;

[0121] When the water level detection result is high, drainage is determined to be necessary, triggering a drain output request. During the drainage process (i.e., when the water level drops to the mid-level), drainage is still determined to be necessary until the water level detection result is low, at which point drainage is determined to be unnecessary and the drain output request is stopped. Furthermore, if the water level is detected at mid-level during power-up, the MCU defaults to a rising process and does not initiate drainage control.

[0122] Under normal circumstances, the low water level sensor should detect water first, followed by the high water level sensor. Under certain test conditions, the high water level sensor may detect water first, which means that the water level is installed in the wrong position, triggering a buzzer and / or flashing light warning to alert the user.

[0123] In the above water level detection method, the water level is confirmed by two sensors, which improves the detection accuracy and reduces the occurrence of false detection.

[0124] The present invention further provides a water accumulation drainage control device, which adopts any of the above-mentioned water accumulation drainage control methods, including:

[0125] a storage unit, configured to store predefined battery voltage multi-level threshold intervals and battery states, wherein each threshold interval corresponds to a different battery state;

[0126] Mains power detection module, used to obtain data on whether there is mains power input;

[0127] Water level detection module, used to obtain water level data;

[0128] Battery voltage detection module, used to periodically obtain battery voltage data;

[0129] Battery status judgment module, used for:

[0130] Get the battery voltage data of the current cycle;

[0131] Recalling the predefined battery voltage multi-level threshold interval and the battery status of the previous cycle stored in the storage unit;

[0132] According to the threshold range that the battery voltage value of the current cycle falls into, the battery status of the current cycle is confirmed.

[0133] Alternatively, according to the threshold interval into which the battery voltage value of the current cycle falls, and when the battery state of the previous cycle meets the target battery state, the battery state of the current cycle is confirmed; and the confirmed battery state of the current cycle is stored in a storage unit;
