Description

Technical Field

[0001] This disclosure relates to the field of ground cleaning equipment technology, and in particular to a drainage control method, device, medium, and base station for a base station. Background Technology

[0002] Currently, existing ground cleaning equipment such as sweepers typically have a base station to hold wastewater after cleaning using an internal tray. Generally, during wastewater discharge, two interactive paths are formed by a drainage pipe equipped with a drainage pump. One path connects to an inlet valve, and the other path connects to a one-way valve for wastewater discharge. The end of the main interactive path connects to another one-way valve for wastewater discharge. Based on this drainage structure, water is first introduced through the inlet valve until the drainage pump is full. Then, the Venturi effect provides external suction, allowing the drainage pump to discharge the wastewater from the base station. Although the one-way valve drainage method prevents water from the inlet valve from flowing back into the base station, if the one-way valve fails, the water entering through the inlet valve can flow back into the base station, posing a risk of water overflow.

[0044] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0045] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0046] The technical solution provided in this disclosure is applicable to a base station, which is matched with a ground cleaning and treatment device. The base station includes a drainage pipe, a tray connected to one end of the drainage pipe, a water level sensing component set at a preset position on the tray, a drainage pump connected in the drainage pipe, and an inlet valve. The drainage pump is a DC drainage pump used to provide drainage power, and the inlet valve is used to pre-inject water into the drainage pipe when the drainage pump is working. The ground cleaning and treatment device may include sweepers, floor scrubbers, or other equipment for cleaning the ground, and is not limited thereto.

[0047] It is easy to understand that when the ground cleaning equipment is a sweeper, the sweeper is matched with a base station, and the base station is used to clean the sweeper's parts to be cleaned, such as the mop. At the same time, the tray in the base station holds the wastewater after cleaning. When the wastewater reaches the preset position of the water level sensor in the tray, the control device controls the water inlet valve and the drain pump to drain the water.

[0048] The base station drainage control method provided in this embodiment compares the duration of the detected full water signal with a preset alarm duration. When the water level cannot be effectively reduced, including when it is determined that the one-way valve has failed, the inlet valve and drainage pump are closed in time, and an alarm is triggered. This avoids the risk of water continuously injected by the inlet valve flowing back into the base station during drainage.

[0049] In some embodiments, based on the detection of a full water signal, the inlet valve and the drain pump are opened simultaneously. When the duration of the full water signal is greater than or equal to the preset alarm duration, the check valve is determined to be faulty, thereby further controlling the drain pump to be shut down and performing alarm processing; or, if the duration of the full water signal is less than the preset alarm duration, the check valve is determined not to be faulty, and the inlet valve and the drain pump are controlled to be closed simultaneously, or the drain pump is shut down after the inlet valve is closed.

[0050] In some embodiments, when a full water signal is detected again after it has disappeared, the inlet valve and the drain pump are opened simultaneously, and the time is re-accumulated to obtain the duration of the current full water signal. Based on this, the duration of the current full water signal is compared with a preset alarm duration, and then related operations are performed. Specifically, if the duration of the full water signal is greater than or equal to the preset alarm duration, the check valve is determined to be faulty, and the drain pump is further controlled to be shut down even though the inlet valve is already closed; or, if the duration of the full water signal is less than the preset alarm duration, the check valve is determined not to be faulty, and the inlet valve and the drain pump are controlled to be closed simultaneously, or the drain pump is shut down after the inlet valve is closed.

[0051] In some embodiments, if no water full signal is detected during the detection process, the inlet valve and drain pump are controlled to close. Specifically, if a water full signal is detected, the inlet valve and drain pump are opened. If the check valve fails, both the inlet valve and drain pump are closed and an alarm is triggered. After the alarm is triggered, the water full signal disappears, and the inlet valve and drain pump remain closed. Alternatively, if a water full signal is detected, the inlet valve and drain pump are opened. If the check valve is not failed, once the water full signal disappears, the inlet valve and drain pump are controlled to close synchronously, or the inlet valve is closed first, and then the drain pump is closed.

[0052] In some embodiments, the base station and the ground cleaning equipment may communicate wirelessly. For example, the wireless transmission method may include local area network transmission such as WIFI or Bluetooth, or wide area network transmission such as 4G or 5G, and none of them are limited here.

[0053] In some embodiments, the control method may be executed by a base station, a ground cleaning and treatment device, a terminal device communicating with the base station, or a terminal device communicating with the ground cleaning and treatment device. The terminal device is equipped with application (APP) software for the control method. The application software interacts with the base station or the ground cleaning and treatment device through close-range communication and further executes the control method.

[0054] The background and improvements of the embodiments of this disclosure will be described by way of example below with reference to the accompanying drawings.

[0055] First, in light of the relevant background, the existing technical problems and the solutions proposed in this disclosure for improvement will be briefly described.

[0056] For example, Figure 1 A schematic diagram of a drainage system provided for the present technology. (Refer to...) Figure 1 The drainage system in the base station includes a drainage pipe 01, a first one-way valve 02, a second one-way valve 03, an inlet valve 04, a drainage pump 05, and a tray (not shown in the figure). The drainage pump 05 is connected to the drainage pipe 01 and is close to the end that outputs sewage. The first one-way valve 02, the inlet valve 04, and the second one-way valve 03 are all connected to the corresponding ports of the drainage pipe 01. One end of the first one-way valve 02 is connected to the internal tray, and the other end is connected to the drainage pipe 01. One end of the second one-way valve 03 is connected to the drainage pipe 01, and the other end is connected to an external water pipe (not shown in the figure) to discharge sewage to the outside. The actual flow path during drainage is shown in the drainage pipe 01 (as indicated by the arrow direction from left to right). After the two pipes in the drainage pipe 01 converge, they form a single pipe to output sewage from the tray. It should be noted that the first one-way valve 02 and the second one-way valve 03 are one-way, allowing water passing through the first one-way valve 02 and the second one-way valve 03 to flow in one direction respectively, thereby preventing water entering through the inlet valve 04 from flowing back into the base station; for example, with Figure 1 Taking the orientation and structure shown as an example, both the first one-way valve 02 and the second one-way valve 03 ensure that the sewage flows to the right. However, when the first one-way valve 02 and the second one-way valve 03 fail, they no longer have one-way properties, allowing the water to flow to the left as well. This causes the water entering through the inlet valve 04 to backflow into the base station.

[0057] It should be noted that the failure of the one-way valve can be caused by dirt or wear and tear of the components, which can cause the water entering through the inlet valve 04 to flow back into the base station, thereby increasing the risk of water from the base station overflowing into the external environment (such as the floor). The causes of the one-way valve failure will not be elaborated here.

[0058] Based on the above drainage structure, water inlet valve 04 is first opened to fill the drainage pipe 01 until the drainage pump 05 is full of water (expelling internal air). Then, the Venturi effect is used to provide external suction, causing the drainage pump 05 to operate and discharge the sewage from the base station tray. For example, the water inlet valve 04 can have a flow rate of 1 L / min. In other embodiments, other flow rates are possible, which can be set according to the actual structure of the water inlet valve 04 and are not limited here.

[0059] Although the drainage method of the one-way valves (first one-way valve 02 and second one-way valve 03) can prevent the water entering the inlet valve 04 from flowing back into the base station, when the one-way valves fail, the water entering the inlet valve 04 will flow back into the base station due to the water entering the inlet valve, thus creating a risk of water overflow.

[0060] Therefore, to address at least one of the aforementioned deficiencies, this disclosure proposes a drainage control method, apparatus, medium, and base station for a base station. The control method includes: detecting a water-full signal; the water-full signal being a signal indicating that the water level in the tray has reached a preset position, collected by a water level sensing component; controlling the opening of an inlet valve and a drainage pump based on the detected water-full signal; and determining the duration of the water-full signal; wherein the inlet valve closes after being open for a first duration; and controlling the shutdown of the drainage pump and issuing an alarm signal when the duration of the water-full signal is determined to be greater than or equal to a preset alarm duration. Thus, by comparing the duration of the detected water-full signal with the preset alarm duration, the inlet valve and drainage pump can be shut down promptly and an alarm can be triggered when the water level cannot be effectively reduced, including when a one-way valve is determined to be faulty. This avoids the risk of water continuously injected into the base station during drainage flowing back into the base station and causing spillage.

[0061] The drainage control method, apparatus, medium, and base station provided in this disclosure are described below with reference to the accompanying drawings.

[0062] For example, Figure 2This is a flowchart illustrating a drainage control method for a base station provided in an embodiment of this disclosure. In this method, the base station and ground cleaning equipment are matched. The base station includes a drainage pipe, a tray connected to one end of the drainage pipe, a water level sensor located at a preset position on the tray, a drainage pump connected in the drainage pipe, and an inlet valve. The drainage pump is a DC drainage pump used to provide drainage power, and the inlet valve is used to pre-inject water into the drainage pipe when the drainage pump is operating. This method can be executed by a corresponding control device provided in this embodiment of the disclosure, for example, by the base station's controller. This control device can be implemented in software and / or hardware. (Refer to...) Figure 2 The method includes the following steps:

[0063] S110, Detect water full signal.

[0064] The water-full signal is a signal generated by a water level sensor indicating that the water level in the tray has reached a preset position. Specifically, the water level sensor is positioned at a preset location on the tray. When the water level reaches or exceeds the preset position, the water level sensor generates a corresponding water-full signal, thereby executing subsequent drainage operations to drain the water from the tray and make the water-full signal disappear.

[0065] It should be noted that the preset position of the water level sensing component can be set according to the actual drainage needs, and there is no specific limitation on the height of the preset position.

[0066] For example, the water level sensing component can be a sensing electrode or other structure that senses the water level. When the water level sensing component is a sensing electrode, the sensing electrode will be activated when the water level reaches or exceeds the height of the sensing electrode, thereby causing the relevant control device to sense that the water is full. In response, the control device, such as the computer board of the base station, will control the opening of the inlet valve and the drain pump to drain the water. The drainage-related operations are described in the following example.

[0067] S120: Based on the detected water full signal, control the inlet valve and drain pump to open, and determine the duration of the water full signal.

[0068] The inlet valve closes after being opened for a first duration. By opening the inlet valve for the first duration, the water flow required for the operation of the drain pump can be provided simultaneously. Usually, the first duration of the inlet valve opening is shorter than the duration of the drain pump opening, so as to facilitate the disappearance of the water full signal. The specific relationship between the opening duration of the inlet valve and the drain pump will be illustrated in the following text.

[0069] Specifically, upon detecting a full water signal, the inlet valve and drain pump are activated to intervene in the full water signal. It should be noted that the inlet valve and drain pump open simultaneously when the full water signal occurs.

[0070] For example, Figure 3This is a timing diagram illustrating a drainage control method for a base station provided in an embodiment of this disclosure.

[0071] Combining the steps for detecting a full water signal described above, refer to... Figure 3 A represents the voltage level corresponding to the full water signal, B represents the voltage level corresponding to the inlet valve, C represents the voltage level corresponding to the drain pump, t1-t9 represent different times, and X1 and X2 represent the two situations corresponding to the one-way valve failure and the one-way valve effectiveness, respectively. Specifically, the voltage level corresponding to the full water signal indicates the presence or absence of the full water signal: a high voltage level indicates that the full water signal has been detected; a low voltage level indicates that the full water signal has not been detected (i.e., the full water signal has disappeared). The voltage level corresponding to the inlet valve indicates the on / off status of the inlet valve: a high voltage level indicates that the inlet valve is open; a low voltage level indicates that the inlet valve is closed. The voltage level corresponding to the drain pump indicates the on / off status of the drain pump: a high voltage level indicates that the drain pump is on; a low voltage level indicates that the drain pump is off. Furthermore, the voltage levels correspond to the times, thus representing the detection status of the full water signal at different times, and the on / off status of the inlet valve and drain pump at different times.

[0072] Reference Figure 3 It is not difficult to understand that when the water full signal is detected at time t1, the inlet valve and the drain pump are opened synchronously.

[0073] For example, refer to Figure 3 By combining different times, when the water full signal is high, it indicates that the water full signal has been detected. Based on this, it can be known that the period when the water full signal is high is the duration of the water full signal, thus determining the duration of the water full signal.

[0074] When the inlet valve and the drain pump are opened synchronously, the control device can accurately determine whether the one-way valve in the base station has failed based on the duration of the full water signal. Based on whether the one-way valve has failed, the control device can further control the inlet valve and the drain pump to perform relevant operations, which will be illustrated in the following text.

[0075] S130. If the duration of the water full signal is greater than or equal to the preset alarm duration, control the shutdown of the drain pump and issue an alarm signal.

[0076] The preset alarm duration can be the duration corresponding to at least one drainage cycle of the drain pump, and the duration corresponding to one drainage cycle can be a second duration. It should be noted that the drainage cycle is based on the on / off operation of the inlet valve, and the drain pump always maintains the cycle corresponding to when it is on. For example, refer to... Figure 3In the case of X1, one cycle of the inlet valve can correspond to one complete switching operation (corresponding to t1-t3), and one drainage cycle of the drain pump (second duration) can be equal to one cycle of the inlet valve. It can be set according to the actual drainage situation and is not limited here; and the second duration will be illustrated in the following text.

[0077] Specifically, based on the detected water full signal, the control device simultaneously controls the inlet valve and the drain pump to perform relevant drainage operations, such as... Figure 3 The operation corresponding to t1-t5 is as follows: when the duration of the water full signal is longer than the preset alarm duration, such as when the water full signal can still be detected at or after t5, the control device determines that the one-way valve has failed. Based on this, it further controls the drainage pump to close and issues an alarm signal, thereby promptly cleaning up the water that cannot be discharged normally due to the failure of the one-way valve, and preventing the water entering the water inlet valve from flowing back into the base station when drainage is carried out in the case of unknown one-way valve failure. The specific control process is illustrated in the following description.

[0078] The base station drainage control method provided in this embodiment compares the duration of the detected full water signal with a preset alarm duration. When the water level cannot be effectively reduced, including when it is determined that the one-way valve has failed, the inlet valve and drainage pump are closed in time, and an alarm is triggered. This avoids the risk of water continuously injected by the inlet valve flowing back into the base station during drainage.

[0079] In some embodiments, the base station further includes a one-way valve disposed in a drain pipe and configured to allow water in the drain pipe to flow unidirectionally from the tray along the drain pipe. Exemplarily, Figure 4 for Figure 2 The method shown is a detailed flowchart of S130. Figure 2 Based on, refer to Figure 4 In this method, S130 may specifically include the following steps:

[0080] S131. If the duration of the water full signal is greater than or equal to the preset alarm duration, the one-way valve is determined to be faulty.

[0081] For example, the preset alarm duration can be the duration corresponding to two drainage cycles of the drain pump, and the duration corresponding to the two drainage cycles can be the second duration. Specifically, when a full water signal is detected and the inlet valve and drain pump are opened simultaneously, the control device controls the drain pump to be in the open state and simultaneously controls the inlet valve to perform one on / off operation, which corresponds to one cycle of the inlet valve. For example, if a full water signal is still detected at the end of one cycle of the inlet valve, it indicates that the relevant operation performed in that cycle failed to achieve normal drainage. In this case, the control device is unsure whether the failure to drain normally is due to the failure of the check valve. Therefore, to prevent misjudgment, the above operation on the inlet valve and drain pump is performed again to determine whether the check valve has failed.

[0082] Specifically, when the preset alarm duration equals the duration of two cycles corresponding to the inlet valve, and simultaneously corresponds to the duration of two drainage cycles corresponding to the drain pump, and the duration of the full water signal exceeds the preset alarm duration, the control device determines that the check valve has failed. This can be understood in conjunction with the above text, and will not be elaborated upon here.

[0083] For example, the preset alarm duration can also be the duration corresponding to one drainage cycle of the drain pump. Specifically, when a full water signal is detected and the inlet valve and drain pump are opened simultaneously, the control device controls the drain pump to be in the open state and simultaneously controls the inlet valve to perform one on / off operation, which corresponds to one cycle of the inlet valve. For example, if a full water signal is still detected at the end of one cycle of the inlet valve, it indicates that the relevant operation performed in that cycle failed to achieve normal drainage. The control device can also directly determine that the check valve has failed, resulting in the inability to drain normally, without having to perform the above operation on the inlet valve and drain pump again to prevent false judgment.

[0084] S132. Based on the failure of the check valve, the drain pump is shut down and an alarm signal is issued.

[0085] For example, refer to Figure 3 Based on the detected water full signal, the inlet valve performs one switching operation (corresponding to t1-t3) and another switching operation (t3-t5) simultaneously, and the drainage pump starts synchronously (corresponding to t1-t5). When the two switching operations of the inlet valve are completed, the water full signal does not disappear, so it can be determined that the one-way valve has failed. On the basis that the inlet valve has been closed, the drainage pump is further controlled to shut down to prevent the water entering from the inlet valve from flowing back into the base station, and an alarm signal is issued.

[0086] For example, alarm signals can be issued using relevant components of base stations, ground cleaning equipment, or terminal equipment, such as the smart display panel of a base station. The alarm signal can be a text or voice prompt to remind the user that the water in the base station tray is full and cannot be drained normally, so that the user can clean the tray in time (such as cleaning dirt) and empty the water in the tray. The form of the alarm signal is not limited here.

[0087] In some embodiments, the control method further includes:

[0088] Once the duration of operation of the drainage pump reaches the second duration, the drainage pump is controlled to shut down; wherein the second duration is longer than the first duration.

[0089] Specifically, the inlet valve is controlled to remain open for a certain duration, and then closed for a certain period of time to form a complete opening and closing operation of the inlet valve.

[0090] For example, the first opening duration of the inlet valve can be 10 seconds, and the corresponding closing duration can be 25 seconds. Correspondingly, the second opening duration of the drain pump is equal to the sum of the opening and closing durations of a complete opening and closing operation of the inlet valve, that is, the duration of one drainage cycle is 35 seconds; thus, synchronous control of the inlet valve and the drain pump is achieved.

[0091] It should be noted that the initial opening time of the inlet valve must be shorter than its closing time to prevent water entering the base station from flowing back into the base station due to excessive opening time. The appropriate duration can be set according to drainage needs. There is no limit to the specific opening and closing time of the inlet valve.

[0092] In some embodiments, the preset alarm duration is an integer multiple of the second duration.

[0093] It is easy to understand that, based on the fact that the second duration is the duration corresponding to one drainage cycle of the drainage pump or the duration corresponding to two drainage cycles of the drainage pump, the preset alarm duration is an integer multiple of the second duration.

[0094] For example, when the second duration is the duration corresponding to one drainage cycle of the drainage pump, the preset alarm duration can be twice the second duration; specifically, if a full water signal is still detected at or after the time corresponding to one drainage cycle of the drainage pump, it indicates that normal drainage has not been achieved, and an alarm signal is immediately issued. Here, the preset alarm duration can be set according to the actual drainage needs, and is not limited here.

[0095] In some embodiments, Figure 2 Based on this, the control method also includes:

[0096] Step 1: Ensure the drain pump is off and check the water full signal again.

[0097] It should be noted that, combined with the above description of the water inlet valve and drainage pump closing simultaneously and issuing an alarm signal, it can be seen that the water in the base station tray was cleared through alarm processing, thereby causing the water full signal to disappear. After the water full signal disappears, the water full signal is detected again to control the water inlet valve and drainage pump to perform subsequent related operations.

[0098] Step 2: Once the water full signal is detected again, control the inlet valve and drain pump to open synchronously at least once more.

[0099] When a full water signal is detected again, the inlet valve and drain pump will be opened synchronously once more, based on the previously closed state. The number of times the inlet valve and drain pump are opened synchronously can be set according to the number of times the full water signal is detected, and is not limited here.

[0100] Among them, the duration of the water full signal is determined based on the detected water full signal, including: the cumulative time since the water full signal was detected to obtain the duration of the water full signal at the current time.

[0101] It is easy to understand that for multiple detections of the full water signal, the duration of the full water signal from the time the full water signal is detected until it disappears is accumulated from the time the full water signal is detected, and the duration of the full water signal for the current time is obtained.

[0102] In some embodiments, in conjunction with steps one and two above, the control method further includes:

[0103] If no full water signal is detected, shut off the inlet valve and drain pump.

[0104] For example, the inlet valve and drain pump are opened upon detecting a full water signal. If the check valve fails, the inlet valve and drain pump are closed and an alarm is triggered. After the alarm is triggered, the full water signal disappears, and the inlet valve and drain pump remain closed. Alternatively, the inlet valve and drain pump are opened upon detecting a full water signal. If the check valve is not failed, the inlet valve and drain pump are closed once the full water signal disappears.

[0105] For example, refer to Figure 3 , Figure 3 The situation corresponding to X2 shows that the water full signal is detected again at time t7. Based on the detection of the water full signal, the inlet valve and the drain pump are opened. The inlet valve performs a complete opening and closing operation (corresponding to t7-t9), while the drain pump remains open. When the water full signal disappears at time t9 (no water full signal is detected at this time), it is determined that the check valve has not failed, and then the inlet valve and the drain pump are controlled to close synchronously.

[0106] In some embodiments, Figure 2 Based on this, the control method also includes:

[0107] If the duration of the full water signal is less than the preset alarm duration, control the inlet valve and drain pump to close synchronously, or control the drain pump to close after the inlet valve is closed.

[0108] For example, when the preset alarm duration is the duration corresponding to two drainage cycles of the drainage pump, refer to Figure 3, Figure 3 The situation corresponding to X1 shows that a water full signal is detected at time t1. Based on the detection of the water full signal, the inlet valve and the drain pump are opened. The inlet valve first performs a complete opening and closing operation (corresponding to t1-t3), while the drain pump remains open. If the water full signal disappears at time t3-t4 (at which time no water full signal is detected), that is, the duration of the water full signal is less than the preset alarm duration, it is determined that the check valve has not failed, and then the inlet valve and the drain pump are controlled to close synchronously.

[0109] Alternatively, based on the detection of a full water signal, the inlet valve and drain pump are opened. During the process of the inlet valve performing two complete opening and closing operations (corresponding to t1-t5), the drain pump remains open. If the full water signal disappears at time t4-t5 (at which point no full water signal is detected), that is, the duration of the full water signal is still less than the preset alarm duration, it is determined that the check valve has not failed. Then, based on the fact that the inlet valve is already closed, the drain pump is further controlled to close, that is, the drain pump is closed after the inlet valve is closed.

[0110] Therefore, by controlling the water inlet valve and drainage pump to close synchronously or asynchronously when the duration of the water full signal is less than the preset alarm duration, the normal drainage of the base station is achieved.
