Flexible flow interception device control system and control method

Abstract

The control method based on the flexible interception device control system includes the following steps: receiving a closing signal from a rainwater sensor switch, the closing signal being triggered when rainwater accumulates in the storage chamber; waking up the flexible interception device control system to its operating mode; receiving an opening signal from a rainwater sensor switch, the opening signal being triggered when rainwater is drained from the storage chamber; and switching the flexible interception device control system to a sleep mode. During rainfall, the storage chamber accumulates rainwater, and the signal generated by the closing of the rainwater sensor switch in the storage chamber wakes up the flexible interception device control system. When rainfall stops, the storage chamber drains the rainwater, and the signal generated by the opening of the rainwater sensor switch causes the flexible interception device control system to switch to sleep mode, achieving the effects of energy saving and cost reduction.

Description

Technical Field

[0001] This invention relates to the field of drainage, and in particular to a control system and control method for a flexible interception device applied in the field of drainage. Background Technology

[0002] Flexible flow-blocking devices are used in the drainage field to close or open drainage pipes. For example, the patent with patent number 202022796182.1, "A Flexible Flow Diversion Device and a Pipeline System with the Flexible Flow Diversion Device," discloses various implementation forms and application scenarios of flexible flow-blocking devices.

[0003] Existing technologies typically use gas stations to provide driving force for flexible interception devices, but the configuration and control of these stations are relatively complex. When multiple flexible interception devices need to be installed in an area, each device requires a gas station, resulting in high costs. Patent application number 202220691488.7, entitled "Pneumatic Control Components, Interception Equipment, and Drainage System," collects rainwater through rainwater downpipes and converts the air pressure in a storage chamber to power the flexible interception device. This solution reduces the overall cost of the flexible interception device control system.

[0004] Flexible interception device control systems typically include monitoring equipment, which may include cameras, level gauges, water quality sensors, rain gauges, pressure sensors, etc., depending on functional requirements. Therefore, flexible interception devices generally require a control cabinet to manage these monitoring devices. Current technologies typically use mains power, solar power, or a combination of both to power the flexible interception device control system. For example, in northern regions with abundant rainfall, mains power is used. In southern regions with less rainfall, solar power is used. In remote areas where mains power is inconvenient, a combination of mains power and solar power can be used. Given the need for low-carbon development, reducing energy consumption is a trend. Reducing the energy consumption of flexible interception device control systems is one of the future research directions, especially for applications using solar power. Lowering energy consumption is even more important, and it also allows for smaller solar panel sizes, reducing the cost of using solar panels. Summary of the Invention

[0005] To partially achieve the above objectives, a first aspect of the present invention provides a flexible flow control system.

[0006] The flexible flow control system includes a water pressure to air pressure control device, a flexible flow control device, and a control cabinet.

[0007] The water pressure to air pressure control device includes a diversion component and a water storage chamber; the diversion component causes the rainwater downpipe to branch from one rainwater channel into at least two rainwater channels, one of which connects to the bottom of the water storage chamber; the water storage chamber is a sealed container with an air vent and a drain outlet; a rainwater sensor switch is installed in the water storage chamber; an electrically controlled valve is installed at the drain outlet of the water storage chamber.

[0008] The flexible interception device has a pressure storage chamber, which is used to open and close the drainage pipe. The pressure storage chamber and the water storage chamber are connected through an exhaust port.

[0009] The control cabinet includes a controller, which is electrically connected to a rainwater sensor switch. The control cabinet is also equipped with a pressure sensor, which is used to monitor the pressure in the accumulator chamber.

[0010] A second aspect of the present invention provides a control method based on a flexible flow interception device control system.

[0011] Receives a closing signal from a rainwater sensor switch, the closing signal being triggered by rainwater entering the water storage chamber;

[0012] Based on the closed signal, switch to the working mode;

[0013] Receives a disconnect signal from the rainwater sensor switch, the disconnect signal being triggered by the drainage of rainwater from the water storage chamber;

[0014] Based on the disconnection signal, switch to sleep mode.

[0015] In the above scheme, the flexible interception device control system utilizes a water pressure to air pressure control device to store rainwater and convert water pressure into air pressure to drive the flexible interception device to close. A rainwater sensor is installed in the water storage chamber of the water pressure to air pressure control device. During non-rainy days, the flexible interception device control system is in a low-power state. When it rains, rainwater enters the water storage chamber through the diversion component, and the closing signal generated by the rainwater sensor in the water storage chamber wakes up the flexible interception device control system to operate. When the rain stops, the water storage chamber is emptied, and the opening signal generated by the rainwater sensor in the water storage chamber causes the flexible interception device control system to switch to sleep mode. This control method achieves energy saving.

[0090] Next, the technical solutions in the embodiments of this specification will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this specification. Obviously, the described embodiments are only relatively preferred embodiments. In this embodiment, a camera is taken as an example for detailed description. Based on the embodiments in this specification, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by this invention.

[0091] [[ID=​​​​​In this application, the "pressure accumulator" is not limited to the following implementations: for example, the flexible flow interceptor consists of a metal outer cylinder and a rubber component attached to the metal outer cylinder, and a pressure accumulator can be formed between the metal outer cylinder and the rubber component; another example is that the flexible flow interceptor is integrally molded from a double-layered rubber component, and a pressure accumulator can be formed between the layers of the rubber component; yet another example is that the rubber component is directly attached and fixed in the pipe, and a pressure accumulator can be formed between the rubber component and the pipe; this application does not limit these, as long as a cavity that can accommodate the power required for the elastic deformation of the flexible flow interceptor is provided, it is within the protection scope of this invention.

[0094] In this application, "diversion assembly" includes, but is not limited to, a tee pipe or a box-shaped body with a tee function. The "tee pipe" is a tee pipe well known to those skilled in the art, including but not limited to T-type tees, Y-type tees, and L-type tees. The "diversion assembly" can be a component that cuts off the rainwater downpipe and connects to the cut-off point of the rainwater downpipe. In short, anything that enables the rainwater downpipe to have at least two water outlet paths is within the protection scope of this application.

[0095] In this application, "rain-sensing switch" includes, but is not limited to, float switches and proximity switches capable of sensing rainwater; including but not limited to Hall effect, inductive, and capacitive types. For example, a float switch can trigger a closed signal under buoyancy and an open signal under gravity. A proximity switch can trigger a closed signal when sensing water pressure and a closed signal when the water pressure disappears.

[0096] Modern buildings typically have rainwater downpipes installed to collect and discharge rainwater during rainfall. In this application, "rainwater downpipe" can refer to an existing rainwater downpipe already present in the building, or a substitute for a rainwater downpipe installed next to the building by those skilled in the art to facilitate the function of a flexible interception device.

[0097] In some applications, flexible interception devices only need to be closed during rain. For example, in the renovation of combined sewer systems in old urban areas, a feasible approach is to adopt a staggered rainwater and sewage separation solution. This involves converting septic tanks in the community into buffer tanks and installing flexible interception devices at the outlet of the buffer tanks. During rain, the flexible interception devices are closed, allowing domestic sewage to be temporarily stored, and only rainwater is discharged into the combined sewer. When the rain stops, the flexible interception devices are opened, and the domestic sewage in the buffer tank is discharged, thus achieving the purpose of staggered discharge. In existing environments, buildings are already equipped with rainwater downpipes for discharging rainwater from the building roofs.

[0098] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments in this specification. Obviously, the described embodiments are merely preferred embodiments. All other embodiments obtained by those skilled in the art based on the embodiments in this specification are within the scope of protection of the present invention.

[0099] Combination Figures 1 to 3 The diagram illustrates the components of the flexible interception device control system. The flexible interception device control system includes a water pressure to air pressure control device, a flexible interception device, and a control cabinet. The water pressure to air pressure control device includes a diversion assembly 11 and a water storage chamber 21; the diversion assembly 11 branches the rainwater downpipe from one rainwater channel into at least two rainwater channels, one of which connects to the bottom of the water storage chamber 21; the water storage chamber 21 is a sealed container with an exhaust port and a drain port, the exhaust port being connected to the pressure storage chamber of the flexible interception device 61, and a rainwater sensor switch 31 electrically connected to the control cabinet 51 is installed in the water storage chamber 21. An electrically controlled valve 41 is also installed at the drain port of the water storage chamber.

[0100] During rainfall, rainwater flowing from the building's roof through the downpipe retains the downpipe's original function while also allowing rainwater to enter the storage chamber 21. The rising water level in the storage chamber 21 generates water pressure, forcing air within it into the pressure storage chamber 21 of the flexible interceptor 61. As water accumulates in the downpipe, the flexible interceptor 61 tends to close. Once the converted air pressure reaches its rated pressure, the flexible interceptor 61 can completely shut off. After rainfall ends, the rainwater stored in the storage chamber 21 is drained, and the flexible interceptor 61 can return to its open state. The flexible interceptor control system in this solution replaces the traditional method of establishing a gas station, effectively utilizing existing environmental resources and reducing costs.

[0101] like Figure 4 As shown, in one embodiment of the electrical control section of the flexible interception device control system, a rainwater sensor switch 31, an electrically controlled valve 41, a pressure sensor, and a rain gauge are electrically connected to the control cabinet 51. For those skilled in the art, the electrically controlled valve 41, pressure sensor, rain gauge, and other electronic devices are optional. Those skilled in the art can select one or more of these electronic devices according to functional requirements. For example, a camera, level gauge, water quality sensor, flow meter, etc.

[0102] Typically, during rainfall, the flexible interception device control system executes relatively complex commands and frequently interacts with cloud servers, local servers, or handheld smart terminals, especially as some monitoring devices operate frequently. However, its workload is significantly less during non-rainy periods. Therefore, this paper provides a solution that allows the flexible interception device control system to operate in a working mode during rainfall and enter a sleep mode during non-rainy periods, thereby achieving energy savings.

[0103] Example 1

[0104] The following is combined with Figure 5 An exemplary description of the control method is provided.

[0105] The control method based on the flexible interception device control system includes the following steps:

[0106] The rain sensor switch 31 is closed, and the closed signal is triggered by rainwater entering the water storage chamber 21.

[0107] Based on the closed signal, switch to the working mode;

[0108] Receive the disconnect signal from the rainwater sensor switch 31, which is triggered by the drainage of rainwater from the water storage chamber 21;

[0109] Based on the disconnection signal, switch to sleep mode.

[0110] In the above scheme, during rainfall, the water storage chamber 21 accumulates rainwater. The signal generated by the closing of the rainwater sensor switch 31 in the water storage chamber 21 can wake up the flexible interception device control system. Simultaneously, the rainwater in the water storage chamber 21 compresses air, which enters the pressure storage chamber of the flexible interception device, causing the device to close. When rainfall stops, the water storage chamber 21 is emptied, and the air in the pressure storage chamber of the flexible interception device flows back to the water storage chamber 21, allowing the device to open. When the rainwater in the water storage chamber 21 is nearly emptied, the signal generated by the opening of the rainwater sensor switch 31 causes the flexible interception device control system to enter a sleep mode. Typically, the flexible interception device control system only frequently performs tasks during rainfall. Therefore, this scheme ensures the normal operation of the flexible interception device while maintaining a low-power state during non-rainy days, only waking up during rainfall, thus achieving energy savings and cost reduction.

[0111] In some feasible implementations, the flexible dam control system can be powered by mains electricity, solar energy, a combination of batteries and mains electricity, or pure solar energy. Using mains electricity, the control method provided in this application can achieve energy savings. Using solar energy or a combination of mains and solar energy can reduce power consumption and allow for smaller solar panel sizes, further reducing costs.

[0112] Example 2

[0113] The following is combined with Figure 6 An exemplary description of the control method is provided.

[0114] The control method based on the flexible flow interception device control system includes the following steps:

[0115] The rain sensor switch 31 is closed, and the closed signal is triggered by rainwater entering the water storage chamber 21.

[0116] Based on the closed signal, switch to the working mode;

[0117] Receive the disconnect signal from the rainwater sensor switch 31, which is triggered by the drainage of rainwater from the water storage chamber 21;

[0118] Based on the disconnection signal, switch to sleep mode.

[0119] In working mode, acquire weather signals;

[0120] Based on the weather signal indicating that the rain has stopped, switch the electronic control valve 41 to the open state.

[0121] In some feasible implementations, the drain outlet of the water storage chamber 21 is much smaller than the inlet of the water storage chamber 21. Therefore, during rainfall, the water inflow rate into the water storage chamber 21 is greater than the drainage rate, allowing the water storage chamber 21 to both store rainwater and form a water seal on the drain outlet, ensuring the airtightness of the water storage chamber 21. When the rain stops, the water storage chamber 21 no longer continuously inflows water, only drains. This method is more energy-efficient and environmentally friendly, but the control precision is lower because the drain outlet is small and prone to clogging. Moreover, the drainage speed is too slow, which may affect the normal opening of the drainage pipe by the flexible interception device. Therefore, using an electrically controlled valve 41 to control the drain outlet is more precise.

[0122] For the scheme using an electrically controlled valve 41 to control the drain outlet, during rainfall, the water storage chamber 21 needs to store water, and the electrically controlled valve 41 needs to close the drain outlet during the water storage process. After the rain stops, the water storage chamber 21 needs to drain water, and the electrically controlled valve 41 needs to open the drain outlet during the drainage process. Therefore, it is necessary to switch the state of the electrically controlled valve 41. Rainfall can be actively detected by the rain sensor switch 31, but the cessation of rain cannot be actively detected by the rain sensor switch 31. Therefore, other means are needed to know when the current rainfall ends so that the state of the electrically controlled valve 41 can be accurately switched.

[0123] One feasible way to obtain weather signals is by accessing a meteorological center. For example, obtaining the time of rain and when the rain will stop. If the weather center indicates that the current rainfall is 2 hours, then the electronically controlled valve 41 can be controlled to open the drain outlet after 2 hours. Alternatively, if the weather center indicates that the current rainfall will end at 14:00, then the electronically controlled valve 41 can be controlled to open the drain outlet after 14:00.

[0124] Another feasible way to obtain weather signals is as follows: the flexible interception device control system also includes a rain gauge, which is electrically connected to the controller. The controller receives feedback signals from the rain gauge and obtains the current weather signal. That is, when the rain gauge is activated or the rain stops, the electronically controlled valve 41 can be controlled to open the drain outlet. When the flexible interception device control system is in a dormant state, the rain gauge cannot work normally. However, after rainfall, the rain sensor switch 31 wakes up the dormant mode of the flexible interception device control system, and the rain gauge can then monitor weather information in real time.

[0125] Example 3

[0126] The following is combined with Figure 7 An exemplary description of the control method is provided.

[0127] The control method based on the flexible flow interception device control system includes the following steps:

[0128] The rain sensor switch 31 is closed, and the closed signal is triggered by rainwater entering the water storage chamber 21.

[0129] Based on the closed signal, switch to the working mode;

[0130] Receive the disconnect signal from the rainwater sensor switch 31, which is triggered by the drainage of rainwater from the water storage chamber 21;

[0131] Based on the disconnection signal, switch to sleep mode.

[0132] In working mode, acquire weather signals;

[0133] Based on the weather signal indicating that the rain has stopped, the first duration is read;

[0134] First duration of timing;

[0135] After the first duration of the timer ends, switch the electronically controlled valve 41 to the open state.

[0136] In application, when the current weather signal indicates rain has stopped, the rainwater in the controlled area may have already completely entered the rainwater pipe, or it may still be en route into the rainwater pipe. By setting a first duration before opening the electrically controlled valve 41 to delay the drainage of the water storage chamber 21, that is, to delay the opening of the flexible interception device, the last section of rainwater is prevented from flowing into the channel intercepted by the flexible interception device before the water collection is completed. For example, a solution for staggered rainwater and sewage separation in combined sewer systems in old urban areas. That is, the septic tanks in the community are transformed into buffer tanks, and a flexible interception device is installed at the outlet of the buffer tank. On non-rainy days, the flexible interception device is opened, and domestic sewage can be discharged normally; when it rains, the flexible interception device is closed, so that domestic sewage is temporarily stored, and only rainwater is discharged into the combined sewer; after the rain stops, the flexible interception device is opened again, and domestic sewage in the buffer tank is discharged, thereby achieving the purpose of staggered discharge. If the electrically controlled valve 41 is opened immediately after rainfall ends, causing the flexible interception device to quickly open its channel, and surface water still needs some time to collect, the last section of rainwater will enter the buffer tank, reducing the concentration of domestic sewage before being discharged to the sewage treatment plant. However, it would be more reasonable for the relatively clean rainwater from the last section to be discharged into rivers or lakes. Therefore, a more reasonable approach is to delay the opening of the electrically controlled valve 41 after a certain time interval when rainfall is not expected, thus delaying the activation of the flexible interception device.

[0137] The initial duration is related to the area controlled by the flexible interception device; generally, the larger the controlled area, the larger the initial duration needs to be. Especially when the initial duration is set too large, rainfall may occur again before the initial duration ends. Therefore, the control method of the flexible interception device control system can also execute the following steps:

[0138] In working mode, acquire weather signals;

[0139] Based on the weather signal indicating that the rain has stopped, the first duration is read;

[0140] First duration of timing;

[0141] If it does not rain during the first timeout period, switch the electronic control valve 41 to the open state after the timeout ends.

[0142] Alternatively, the control method of the flexible flow control device control system can also perform the following steps:

[0143] In working mode, acquire weather signals;

[0144] Based on the weather signal indicating that the rain has stopped, the first duration is read;

[0145] First duration of timing;

[0146] If it rains during the first duration, the first duration will be reset.

[0147] The above solution takes into account more complex scenarios in reality. For example, the characteristics of rainfall differ between the south and the north. For example, the characteristics of rainfall differ between summer and winter. The first duration of timing is performed after the rain stops. During this process, it may rain again. If it rains again, the first duration is reset to zero, and the monitoring of rain cessation information continues. The first duration is reset after the rain stops. If no new rainfall information is detected during this process, the electronic control valve 41 is switched to the open state.

[0148] In this control method, weather signals are obtained by accessing a meteorological center or rain gauge while the controller is in operation. Although rain sensing switch 31 can also detect rainfall when it rains, the main function of the rain sensing switch 31 closing signal is to wake up the controller's operating mode. Accessing the meteorological center or rain gauge can detect when the rain has stopped, the purpose of which is to control the switching state of the electronic control valve 41 after the rain stops; accessing the meteorological center or rain gauge can detect when rainfall occurs, the purpose of which is not to control the switching state of the electronic control valve 41 if rainfall occurs again during the first time period.

[0149] Example 4

[0150] See Figure 7 An exemplary description of the control method is provided.

[0151] The control method based on the control system of the flexible interception device includes the following steps:

[0152] In working mode, acquire weather signals;

[0153] Based on the weather signal indicating that the rain has stopped, switch the electronic control valve 41 to the open state.

[0154] After the control valve 41 is switched to the open state, the second duration is read.

[0155] The electronically controlled valve 41 is kept open during the second duration.

[0156] After the second timeout period ends, the control valve 41 switches to the closed state.

[0157] Normally, after rainfall ends, the rainwater accumulated in the water storage chamber 21 needs to be drained to open the flexible interception device. After the rainwater is drained, the electrically controlled valve 41 is closed again so that the water storage chamber 21 can store water when it rains again. Therefore, during the drainage process, the electrically controlled valve 41 should ensure that the drain outlet is open. That is, the electrically controlled valve 41 remains open for a second period of time. The second period of time can be set according to the time required to drain the rainwater accumulated in the water storage chamber 21.

[0158] Those skilled in the art can set the second time based on the time required to empty the rainwater accumulated in the water storage chamber 21. The setting of the second time takes into account the volume of the water storage chamber 21 and the size of the drain outlet. For example, if the water storage chamber 21 is 30L and the diameter of the drain outlet is 20mm, and it takes 5 minutes to empty the water storage chamber 21 when it is full, then the second time can be set to 5 minutes.

[0159] Based on the above control steps, the following steps are also included: if no closing signal is received from the rain sensor switch 31 after the second time period ends, an alarm signal is triggered.

[0160] In the above scheme, under normal circumstances, after the second timeout period ends, the rainwater in the water storage chamber 21 should be emptied, and the controller should receive a closing signal from the rainwater sensor switch 31. If this closing signal is not received in actual operation, a fault is determined to have occurred, thereby triggering an alarm signal to notify maintenance personnel for repair.

[0161] Furthermore, based on the above control method, the following steps may also be included:

[0162] After the second timeout period ends, a closing signal is received from the rain sensor switch 31;

[0163] After the third duration is read, and the timing ends based on the third duration, the electronic control valve 41 is switched to the closed state.

[0164] Normally, after rainfall ends, the electrically controlled valve 41 needs to be opened to drain the rainwater from the storage chamber 21, allowing the flexible interception device to return to its open state. After the rainwater in the storage chamber 21 is drained, the electrically controlled valve 41 is closed again, allowing the storage chamber 21 to continue storing water and closing the flexible interception device during the next rainfall. When the rainwater sensor switch 31 receives the disconnect signal, a small amount of rainwater may still remain in the path from the rainwater sensor switch 31 to the outlet. To ensure that the rainwater in the storage chamber 21 is completely drained when the electrically controlled valve 41 is closed, setting a third time interval is more reasonable.

[0165] Those skilled in the art can set the third duration based on the drainage time from the rainwater sensor switch 31 in the water storage chamber 21 to the drain outlet. For example, if the distance from the rainwater sensor switch 31 to the drain outlet is only 1 cm, and it takes about 3 seconds to drain this section of rainwater, then setting the third duration to 3 seconds or more is reasonable.

[0166] Example 5

[0167] See Figure 8 An exemplary description of the control method is provided.

[0168] The control method based on the control system of the flexible interception device includes the following steps:

[0169] In working mode, the pressure data within the storage tank is acquired in real time.

[0170] or,

[0171] In working mode, the pressure data within the storage tank is acquired in real time;

[0172] The control display device displays the pressure data.

[0173] or,

[0174] In working mode, the pressure data within the storage tank is acquired in real time;

[0175] The real-time pressure data is compared with the calibrated pressure, which is the rated pressure required for the accumulator chamber to be completely closed.

[0176] If the real-time pressure data is less than the calibrated pressure, the control display device displays the first state, which indicates that the accumulator chamber is closed.

[0177] Based on the real-time pressure data being equal to or greater than the calibrated pressure, the control display device displays a second state, which indicates that the accumulator chamber is closed.

[0178] or,

[0179] The control display device displays the pressure data;

[0180] The pressure data acquired in real time is compared with the calibrated pressure, which is the rated pressure required for the accumulator chamber to be completely closed.

[0181] If the real-time pressure data is less than the calibrated pressure, the control display device displays the first state, which indicates that the accumulator chamber is closed.

[0182] Based on the real-time pressure data being equal to or greater than the calibrated pressure, a second state is displayed on the display device, indicating that the accumulator chamber is closed.

[0183] During rainfall, the water pressure to air pressure control device compresses the air in the water storage chamber 21 into the flexible interceptor, generating pressure on the flexible interceptor. The driving pressure of flexible interceptors of different specifications may be the same, similar, or significantly different. The current status of the flexible interceptor can be determined by setting comparison parameters based on its current operating pressure. In intelligent management, establishing a real-time monitoring control system for the flexible interceptor via a server, control cabinet 51, or handheld terminal is a common approach. Therefore, it is usually necessary to observe the dynamics of the flexible interceptor by viewing its pressure data. Thus, the display device can be one or more of the following: the control cabinet 51 display screen, the server display screen, or the handheld terminal display screen. Regarding the display method, it can display only the pressure data in real time; it can also not display pressure data, but instead display only the status of the flexible interceptor based on the comparison between the real-time monitored pressure data and the calibrated pressure; or it can display both the real-time monitored pressure data and the status of the flexible interceptor based on the comparison between the real-time monitored pressure data and the calibrated pressure.

[0184] Example 6

[0185] See Figure 9 An exemplary description of the control method is provided.

[0186] In working mode, acquire weather signals;

[0187] Based on the weather signal indicating that the rain has stopped, switch the electronic control valve 41 to the open state;

[0188] Read the second duration and start timing the second duration;

[0189] The electronically controlled valve 41 is kept open during the second duration.

[0190] Obtain pressure data within the pressure storage area;

[0191] After the second duration of timing ends, the disconnection signal and pressure data of the rain sensor switch 31 are obtained;

[0192] If a disconnect signal is received from the rain sensor switch 31 and the pressure data is zero, switch the electronic control valve 41 to the closed state.

[0193] If no disconnection signal is received from the rain sensor switch 31 or the pressure data is not zero, a fault alarm signal will be sent.

[0194] Based on the above scheme, it is reasonable for those skilled in the art to set a second time interval, that is, after the rainwater in the water storage chamber 21 is emptied, the disconnect signal from the rainwater sensor 31 can be received and the pressure data from the pressure sensor is zero. If, after the second time interval is set, the disconnect signal from the rainwater sensor 31 is still not received or the pressure data from the pressure sensor is not zero, it is possible that the rainwater sensor 31 is damaged or blocked by impurities in the rainwater, or that the pressure sensor is faulty and cannot transmit the signal normally, or that the solenoid valve 41 is faulty and cannot open the drain outlet of the water storage chamber 21 normally; or that the drain outlet is blocked by impurities in the rainwater. Therefore, it is necessary to report an alarm signal in order to troubleshoot the fault in a timely manner.

[0195] After the second time interval, compared to judging the current state of the flexible flow interceptor control system solely based on the rainwater sensor switch 31, the method of comprehensively judging the current state of the flexible flow interceptor control system using both the rainwater sensor switch 31 and pressure data is more effective. That is, after the second time interval, if the pressure is zero and the rainwater sensor switch 31 triggers an open signal, this can be considered a normal result. If the pressure is not zero but the rainwater sensor switch 31 triggers an open signal, it may indicate a pressure sensor malfunction. If the pressure is zero but the rainwater sensor switch 31 does not trigger an open signal, it may indicate a rainwater sensor switch 31 malfunction. If the pressure is not zero and the rainwater sensor switch 31 does not trigger an open signal, it may indicate a malfunction of the electronic control valve 41 or a blockage in the drain outlet.
