Description

Technology Field

[0001] The present invention relates to a septic tank operation status verification system, and more specifically, to a septic tank operation status verification system that verifies the operation status of each septic tank so that a central management center can verify whether wastewater is being purified and discharged in multiple households located in areas where it is not possible to verify through bidirectional communication from the central management center whether wastewater is being purified and discharged. Background Technology

[0003] Generally, since wastewater generated in densely populated urban areas undergoes a purification process in a single septic tank before being discharged, a central management center can easily check and manage whether the wastewater is being purified and discharged through two-way communication.

[0004] However, in rural areas where many households are far apart, wastewater is generally purified through individual tanks and discharged into rivers rather than being integrated into a single septic tank; consequently, there are many cases where a central management center cannot even verify, let alone manage, whether the wastewater is being purified and discharged through two-way communication.

[0005] In particular, even if only a few households among many do not purify their wastewater, the wastewater flows directly into the river, causing environmental pollution. Furthermore, even if there is only one household, since the purification process of wastewater is carried out through multiple stages of aeration in the septic tank, environmental pollution of the river is inevitable even if just one aeration unit does not function properly.

[0006] Consequently, in areas where the central management center cannot manage or even verify whether wastewater is being purified and discharged through two-way communication, they are forced to spend a considerable amount of money to establish one-way communication if two-way communication with the central management center is not possible; however, if even this is not feasible, local officials are visiting households individually to check the condition of the septic tanks.

[0007] However, even if officials from the competent area visit individual households to check the condition of the septic tanks, there is an inevitable problem that the response will be delayed because real-time monitoring is not performed even if a problem occurs with any one septic tank. The problem to be solved

[0009] The present invention is an invention devised to solve the problems of the aforementioned prior art, and the problem to be solved through the present invention is to provide a septic tank operation status checking system that checks the operation status of each septic tank so that the central management center can check whether wastewater is being purified and discharged from multiple households, even in areas where the central management center cannot check whether wastewater is being purified and discharged through two-way communication.

[0010] The problems of the present invention are not limited to those mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below. means of solving the problem

[0012] A septic tank operation status verification system according to the present invention for solving the aforementioned problem may be configured to include: a transmission unit provided in the septic tank to collect the status of the septic tank, converts the collected status of the septic tank into data, and transmits the data to a gateway provided between the central management center and the plurality of households, wherein the central management center cannot verify whether wastewater is purified and discharged through bidirectional communication, and the system verifies the operation status of each septic tank so that the central management center can verify whether wastewater is purified and discharged from a plurality of households having different septic tanks located in an area where the central management center cannot verify; and a management server that verifies the operation status of each septic tank from the data received through the gateway and provides an alarm to a household or the central management center where it is confirmed that the septic tank is not operating.

[0013] Here, the transmitting unit converts the on / off status of the driving unit that drives the aeration unit provided in the septic tank to purify the wastewater and the status of the wastewater contained in each of the septic tanks into data and transmits it to the gateway, and the management server determines the operating status of each of the septic tanks through the data regarding the on / off status of the driving unit among the data, and verifies the operating status of each of the septic tanks using the data regarding the status of the wastewater contained in each of the septic tanks when a request is made from a household or the central management center confirming that the septic tank is not operating, or when the operating status of each of the septic tanks is checked at a preset period, thereby confirming the operating status of each of the septic tanks.

[0014] At this time, the transmitting unit may be configured to include: a driving unit verification module that checks the operating status of the driving unit; a sensor module that checks at least one of the oxygen demand, nitrogen content, and phosphorus content of the wastewater contained in each of the purification tanks; a data conversion module that converts the data to 1 (on) if the operating status of the driving unit confirmed by the driving unit verification module is operating and converts the data to 0 (off) if it is not operating, and converts the data to 1 (on) if the value of at least one of the oxygen demand, nitrogen content, and phosphorus content confirmed by the sensor module is less than a preset value and converts the data to 0 (off) if it is greater than or equal to the preset value; and a communication module that transmits the data converted through the data conversion module to the gateway.

[0015] In addition, the communication module may be configured to transmit the data to the gateway via LoRa communication.

[0016] Meanwhile, the above management server may be configured as an edge computer including the above gateway.

[0017] Additionally, the management server may be configured to include: a setting module that sets operating information of the normal operating state of the driving unit according to the type of driving unit provided in the furniture; a judgment module that determines the operating state of the septic tank by comparing the operating information set by the setting module with data regarding the on / off state of the driving unit received through the gateway; and a location confirmation module that confirms the location of the furniture having the septic tank equipped with the transmitting unit, which transmits the data regarding the on / off state of the driving unit to the gateway.

[0018] At this time, the setting module may be configured to generate driving information by classifying the on / off state of the driving unit according to the type of driving unit provided in the furniture into a preset pattern, and to transmit the driving information generated according to the preset pattern to the judgment module while also transmitting the location information of the furniture confirmed by the location verification module.

[0019] In addition, the judgment module may be configured to compare the driving information set by the setting module with the data regarding the on / off state of the driving unit received through the gateway to determine whether the driving information and the data regarding the on / off state of the driving unit match, and if it is determined that the driving information and the data regarding the on / off state of the driving unit do not match, to confirm that the septic tank is not operating, and to designate the household as one in which the septic tank is confirmed not to be operating based on the location information of the household confirmed by the location verification module.

[0020] In addition, the judgment module may be configured such that when it is determined that there is a discrepancy between the driving information and the data regarding the on / off state of the driving unit, if it is determined that the driving information and the data regarding the on / off state of the driving unit match within a preset error range based on the driving information, it confirms that the septic tank is operating and releases the designation of the household as not operating the septic tank.

[0021] At this time, the judgment module may be configured to verify the operating status of each of the septic tanks using data on the state of the wastewater when a request is made by a household that confirms that the septic tank is not operating, and if the data on the on / off state of the drive unit matches the data on the state of the wastewater as 0, which is the off state, it may be configured to reconfirm that the septic tank is not operating and provide an alarm to the household that confirms that the septic tank is not operating or to the central management center. Effects of the invention

[0023] According to the septic tank operation status verification system of the present invention presented as a solution as described above, even in areas where it is not possible to verify whether wastewater is purified and discharged through two-way communication at the central management center, the central management center can verify whether wastewater is purified and discharged from multiple households.

[0024] The effects of the present invention are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art from the description in the claims. Brief explanation of the drawing

[0033] First, the overall configuration of an embodiment of a septic tank operation status verification system according to the present invention will be described in detail with reference to FIGS. 1 and 2.

[0034] Here, FIG. 1 is a drawing illustrating an embodiment of a septic tank operation status checking system according to the present invention, and FIG. 2 is a drawing illustrating the configuration of an embodiment of a septic tank operation status checking system according to the present invention.

[0035] As illustrated in FIGS. 1 and 2, one embodiment of the sewage treatment tank operation status checking system according to the present invention may be configured to include a transmission unit (100) and a management server (200).

[0036] At this time, the transmitting unit (100) is configured to collect the state of the purification tank (T) provided in the purification tank (T), convert the collected state of the purification tank (T) into data, and transmit the data to a gateway (S) provided in a transit point between the central management center (C) and a number of households (H).

[0037] The state of the purification tank (T) collected by the transmitting unit (100) is the on-off state of the driving unit that drives the aeration unit provided in the purification tank (T) to purify the wastewater, and the state of the wastewater contained in each purification tank (T).

[0038] In other words, since the condition of the purification tank (T) can be confirmed as the wastewater is not being purified if the aeration unit that supplies oxygen to purify the wastewater is not operating, the on / off status of the drive unit, such as the motor and actuator that drive the aeration unit, is collected as the condition of the purification tank (T) and converted into data.

[0039] In addition, if the wastewater has been purified, the values ​​for oxygen demand, nitrogen content, phosphorus content, etc., as a condition of the wastewater contained in the septic tank (T) will inevitably improve. Therefore, since the condition of the septic tank (T) can be confirmed as having purified wastewater, this is collected and converted into data.

[0040] At this time, oxygen demand includes chemical oxygen demand (COD), which refers to the amount of oxygen consumed when organic matter in water is decomposed by an oxidizing agent (e.g., potassium dichromate), and biochemical oxygen demand (BOD), which refers to the amount of oxygen consumed when microorganisms decompose organic matter in water.

[0041] In addition, nitrogen content refers to the total nitrogen content of nitrogen compounds (ammonia, nitrate, nitrite, etc.) contained in water, which is one of the main causes of eutrophication, and phosphorus content refers to the total phosphorus content in water, which is one of the main causes of eutrophication and algal blooms.

[0042] A transmission unit (100) that collects the state of such a sewage treatment tank (T), converts it into data, and transmits the data to a gateway (S) can be configured in various structures in a form provided in the sewage treatment tank (T), and it goes without saying that the scope of rights is not limited as a result.

[0043] However, for further detailed explanation, the transmitting unit (100) may be configured to include a driving unit verification module (120), a sensor module (140), a data conversion module (160), and a communication module (180).

[0044] At this time, the drive unit verification module (120) is configured to verify the operating status of the drive unit, and there are no restrictions on the method or configuration as long as the on / off status of the drive unit can be verified, and for example, it can be configured as a device that measures whether power is consumed by a motor or actuator.

[0045] Meanwhile, the sensor module (140) is configured to check at least one of the oxygen demand, nitrogen content, and phosphorus content of the wastewater contained in each of the purification tanks (T). Although it can measure the oxygen demand, nitrogen content, and phosphorus content, in this case, a large number of sensors are required, which may result in high production and maintenance costs. Therefore, to save on these costs, it may be configured to check only the oxygen demand.

[0046] Meanwhile, the data conversion module (160) is configured to resolve the issue that if the values ​​measured by the driving unit verification module (120) or the sensor module (140) are to be transmitted as is through the communication module (180) to be described later, the data capacity is large, making the configuration of the communication module (180) complex and costly.

[0047] If such a data conversion module (160) also converts values ​​measured by the driving unit verification module (120) or the sensor module (140) into data to facilitate communication, there are no restrictions on the method or configuration, and it is obvious that the scope of rights is not limited as a result.

[0048] However, for further detailed explanation, the data conversion module (160) may be configured to convert the data to 1 (on state) when the operating state of the driving unit confirmed by the driving unit confirmation module (120) is operating, and to convert the data to 0 (off state) when it is not operating.

[0049] Additionally, the sensor module (140) can be configured to convert the data to an ON state of 1 when at least one of the oxygen demand, nitrogen content, and phosphorus content values ​​is less than a preset value, and convert the data to an OFF state of 0 when it is greater than or equal to a preset value.

[0050] Meanwhile, the communication module (180) is configured to transmit data converted through the data conversion module (160) to the gateway (S), and can be configured in various ways, ranging from unidirectional long-distance wireless communication to bidirectional short-distance wired communication.

[0051] In particular, considering that the location requiring an embodiment of the septic tank operation status verification system according to the present invention is a rural area where it is not possible to verify whether wastewater is purified and discharged through bidirectional communication from the central management center (C), it would be advantageous in terms of facility construction and maintenance to configure the embodiment of the septic tank operation status verification system according to the present invention to place an edge computer including a gateway (S) and a management server (200) at a public institution facility such as a community center or health center as described below, and to configure the communication module (180) to transmit data to the gateway (S) via a unidirectional long-distance wireless communication facility before the result of determining whether wastewater is purified and discharged from the management server (200) is transmitted again to the central management center (C) via bidirectional short-distance wired communication.

[0052] At this time, LoRa communication may be an example of a unidirectional long-distance wireless communication method for transmitting data from the communication module (180) to the gateway (S), and the communication module (180) may be configured accordingly.

[0053] Meanwhile, the management server (200) is configured to check the operating status of each septic tank (T) from the data received through the gateway (S) and provide an alarm to a household or central management center (C) where it is confirmed that the septic tank (T) is not operating.

[0054] In particular, this management server (200) can be configured to determine the operating status of each septic tank (T) through data regarding the on / off status of the drive unit among the data received by the gateway (S), and to verify the operating status of each septic tank (T) by verifying the operating status of each septic tank (T) using data regarding the status of wastewater contained in each septic tank (T) when a request is made from a household or central management center (C) where it is confirmed that the septic tank (T) is not operating, or when there is a request to check the operating status of each septic tank (T) at a preset period.

[0055] As long as such a management server (200) can check the operating status of each septic tank (T), there are no restrictions on the method or configuration, and it is obvious that the scope of rights is not limited as a result.

[0056] However, for a more detailed explanation, the management server (200) may be configured to include a setting module (220), a judgment module (240), and a location verification module (260).

[0057] Here, the setting module (220) is configured to set driving information of the normal operating state of the driving unit according to the type of driving unit provided in a plurality of furniture, and a detailed explanation regarding the setting of driving information will be described later with reference to FIGS. 3 to 7.

[0058] Meanwhile, the judgment module (240) is configured to determine the operating status of the purification tank (T) by comparing the driving information set by the setting module (220) with the data on the on / off status of the driving unit received through the gateway (S), and this will also be described later with reference to FIGS. 3 to 7.

[0059] Meanwhile, the location verification module (260) is configured to verify the location of a household (H) having a purification tank (T) equipped with a transmission unit (100) that transmits data about the on / off status of the drive unit to the gateway (S).

[0060] Through this location verification module (260), households that are confirmed not to be operating the septic tank (T) can be designated, and an alarm can be given to the households to restart the septic tank (T).

[0061] The management server (200) configured in this manner may be provided at the central management center (C), and there are no restrictions on its location, such as being provided at an intermediate location situated between multiple households (H) and the central management center (C).

[0062] If a management server (200) is provided at a transit point, the management server (200) may be configured as an edge computer including a gateway (S) provided at the transit point.

[0063] In this context, a gateway (S) is a general term for a device or software that enables data exchange between different networks, protocols, or systems, and an edge computer is a general term for a computer that processes data at the device where the data is generated or at a nearby network edge, instead of performing data processing at a central data center or cloud.

[0064] In this way, if the management server (200) is configured as an edge computer including a gateway (S) provided at an intermediate location, it is possible to process data in real time without transmitting data to a central management center (C), reduce transmission time, and contribute to increasing the responsiveness and efficiency of an embodiment of the sewage treatment tank operation status check system according to the present invention.

[0065] Next, with reference to FIGS. 3 to 7, the operation of a management server (200) included in one embodiment of the sewage treatment tank operation status verification system according to the present invention, which was previously described with reference to FIGS. 1 and 2, will be explained in more detail.

[0066] Here, FIG. 3 is a drawing illustrating the operation of an example of a management server included in an embodiment of a septic tank operation status checking system according to the present invention, FIG. 4 is a drawing illustrating the setting module of an example of a management server that can be explained through FIG. 3, and FIG. 5 to 7 are drawings illustrating the judgment module of an example of a management server that can be explained through FIG. 3.

[0067] As illustrated in FIG. 3, the management server (200) first sets the operating information of the normal operating state of the drive unit through the setting module (220), and then compares the data regarding the on / off state of the drive unit received through the gateway (S) with the set operating information through the judgment module (240).

[0068] At this time, the setting module (220) may be configured to generate driving information by classifying the on / off state of the driving unit according to the type of driving unit provided in the furniture (H) into a preset pattern, and to transmit the driving information generated according to the preset pattern to the judgment module (240), while also transmitting the location information of the furniture (H) confirmed by the location confirmation module (260).

[0069] Subsequently, the judgment module (240) determines that the septic tank (T) is operating normally if the values ​​obtained by comparing the operating information set by the setting module (220) with the data on the on / off status of the driving unit received through the gateway (S) match, and determines that the septic tank (T) is not operating normally if it does not, and designates the household where the septic tank (T) is not operating normally and gives an alarm to the household or the central management center (C).

[0070] In this case, if it is determined that there is a discrepancy between the driving information and the data regarding the on / off status of the driving unit, the household where the septic tank (T) is not operating normally is immediately designated and an alarm is sent to the said household or the central management center (C). This represents a very high setting of the sensitivity of one embodiment of the septic tank operation status verification system according to the present invention. Setting the sensitivity high in this way may cause inconvenience due to malfunction.

[0071] Accordingly, it would be advantageous for the judgment module (240) to be configured such that when it is determined that there is a discrepancy between the driving information and the data regarding the on / off state of the driving unit, if it is determined that the driving information and the data regarding the on / off state of the driving unit match within a preset error range based on the driving information, it confirms that the septic tank (T) is operating and releases the household designated as not operating the septic tank (T).

[0072] Meanwhile, in households where it is confirmed that the septic tank (T) to which the alarm was sent is not operating because the data regarding the operating information and the on / off status of the operating unit is judged to be inconsistent outside the preset error range, the septic tank (T) will be inspected and a request for verification will be made to the management server (200).

[0073] In this case, the judgment module (240) verifies the operating status of the septic tank (T) using data on the state of the wastewater, and if the data on the on / off state of the drive unit matches the data on the state of the wastewater as 0, which is the off state, it reconfirms that the septic tank (T) is still not operating and provides an alarm to the household or central management center (C) that confirms that the septic tank (T) is not operating.

[0074] Regarding the operation of the management server (200) as described above, the following is an example of the operation information set by the setting module (220), data on the on / off status of the drive unit, and data on the status of the wastewater.

[0075] First, the purification tank (T) may be equipped with multiple driving units according to various configurations provided for the purification process, and it is assumed that, for example, there are a first driving unit (D1), a second driving unit (D2), and a third driving unit (D3) for driving a first aeration tank, a second aeration tank, and a sedimentation tank.

[0076] At this time, the transmitting unit (100) is connected to the first driving unit (D1), the second driving unit (D2), and the third driving unit (D3) provided in the purification tank (T), and the driving unit verification module (120) checks the operation of the first driving unit (D1), the second driving unit (D2), and the third driving unit (D3) as whether it is on or off, and can transmit the on / off status of the first driving unit (D1), the second driving unit (D2), and the third driving unit (D3) to the management server (200) through the communication module (180) as data regarding the on / off state.

[0077] That is, when wastewater is discharged, the first drive unit (D1) can be driven to prioritize the operation of the first aeration tank, and the second aeration tank can be turned on or off depending on the operation time of the first aeration tank, and the sedimentation tank can be kept in an off state while the first aeration tank is operating. Therefore, the drive unit verification module (120) transmits the on / off status of the first drive unit (D1), the second drive unit (D2), and the third drive unit (D3) to the management server (200) as data regarding the on / off state.

[0078] At this time, the setting module (220) can set driving information based on whether it is on or off when in a normal state according to the first driving unit (D1), the second driving unit (D2), and the third driving unit (D3), and transmit it to the judgment module (240).

[0079] More specifically, as shown in FIG. 4, the setting module (220) can set whether the operating state and the stopped state are repeated during a preset period by expressing the case where the driving unit is in an operating state as 1 and the case where it is in a stopped state as 0.

[0080] In addition, considering the case where the drive unit verification module (120) transmits on / off status information based on a preset cycle, it can be set to check the on / off status information for the first drive unit (D1), the second drive unit (D2), and the third drive unit (D3) based on a preset cycle, and if necessary, the preset cycle can be set to have different times based on one cycle of the purification process.

[0081] To give a more detailed example based on the premise that the setting module (220) is set up in this way, as shown in FIG. 5, the judgment module (240) can compare the on / off state information of the lower part with the driving information of the upper part, and the judgment module (240) can determine whether the driving part is operating by comparing the on / off state information based on the preset period set by the setting module (220).

[0082] For example, when it is T1, the driving information of the first driving unit (D1) in a normal state is displayed as 011, but if the operating state of the first driving unit (D1) transmitted as on / off state information is transmitted as 111, the 011 and 111 are compared to determine that they are different, and the judgment module (240) can determine that there is an abnormality in the on / off state information.

[0083] However, since such cases can be judged by being transmitted in real time, it may be difficult to use transmission based on an accurate time zone, so the judgment module (240) may determine that the driving information and the on / off status information match based on a preset error range and determine that it is in a normal state.

[0084] That is, the first driving unit (D1) must transmit 110 within the time T2 as shown in FIG. 5 based on the driving information, but only 10 is transmitted within T2 in the on / off state information, and if a signal of 0 is transmitted between T2 and T3, the judgment module (240) determines whether the signal of 0 is within a preset error range, and if it is determined to be within the preset error range, the purification tank (T) can be determined to be in a normal state.

[0085] However, since the driving information is compared based on the on / off status information transmitted in real time, setting a preset error range for each range may be practically complicated, so as shown in FIG. 6, the abnormal state of the septic tank (T) may be determined based on whether the on / off signal is repeated within a preset period set by the setting module (220).

[0086] Here, the preset cycle set in the setting module (220) may be performed based on the purification process, or may be set by the management server (200) or the central management center (C). However, if explained based on the purification process, the first drive unit (D1), the second drive unit (D2), and the third drive unit (D3) do not operate, and the first aeration tank, the second aeration tank, and the sedimentation tank do not operate during the non-operation time (E). Based on T1, when the first drive unit (D1) operates to operate the first aeration tank, T2, when the second drive unit (D2) operates, and T3, when the third drive unit (D3) operates, the state in which an on / off signal is not transmitted during the non-operation time (E) is determined to be normal, and the abnormal state of the purification tank (T) may be determined based on the number of times an on / off signal is transmitted during T1, T2, and T3, respectively.

[0087] That is, the state of the purification tank (T) can be determined based on the number of on / off operations of the first drive unit (D1), the second drive unit (D2), and the third drive unit (D3) within the time T1, T2, and T3.

[0088] Meanwhile, if the judgment module (240) intends to verify the operating status of the septic tank (T) using data regarding the state of the wastewater, it can check whether the on / off signal and the data regarding the state of the wastewater match within a preset period set by the setting module (220) as shown in FIG. 7.

[0089] That is, the first sensor unit that measures the oxygen content of the wastewater contained in the first aeration tank at time T1 distinguishes whether the preset oxygen content is correct or not; if it is correct, it is verified based on the data converted to 1 (on state), and if it is not correct, it is verified based on the data converted to 0 (off state). If it matches the data 011 for the driving state of the first driving unit, it can be verified that the purification tank (T) is operating normally.

[0090] This can be verified in the same way based on data converted to 1 or 0 based on the oxygen content measured by the second sensor unit that measures the oxygen content of the wastewater contained in the second aeration tank and the third sensor unit that measures the oxygen content of the wastewater contained in the sedimentation tank.

[0091] As previously explained, at this time, what is measured by the first to third sensor units may be not only the oxygen content but also at least one of the oxygen demand, nitrogen content, and phosphorus content of the wastewater contained in each septic tank.

[0092] Although embodiments of the present invention have been described above with reference to the drawings, various modifications and changes may be made without departing from the spirit or scope of the invention as defined by the following claims, and such changes should also be included within the scope of the present invention.
