Description

[Technical Field]

[0001] The present invention relates to a drainage pumping station operation support system that supports the operation of pumps, gates, and other equipment at a drainage pumping station in a river, a remote monitoring system, and an operation guidance providing method. [Background technology]

[0002] A monitoring system that supports the operation of equipment such as pumps and gates at drainage pumping stations on rivers collects status signals and measurement signals for each piece of equipment, river water level signals, etc., to operate the drainage pumping station, and displays these on a screen that schematically represents the drainage pumping station and a screen that displays a time-series graph, and also predicts the inflow to the drainage pumping station based on the water level signals and rainfall signals from upstream of the river, taking into account data on past water levels and rainfall, and displays operational guidance for equipment operation on the screen based on basic rules related to drainage pumping station operation, thereby providing information to operators in charge of drainage pumping station operation. For example, an example of a monitoring system with this configuration is the drainage pumping station pump operation support system disclosed in Japanese Patent Laid-Open No. 8-100771, "River Drainage Pumping Station Pump Operation Support System" (Patent Document 1).

[0003] In addition, the remote monitoring system that supports the operation of equipment at multiple drainage pumping stations aims to prevent delays in operations caused by the faster rise in river water levels due to larger typhoons and increased rainfall, as well as to provide logistical support to operators as drainage pumping stations operate for longer periods of time.In order to operate multiple drainage pumping stations remotely in a river basin, status signals, measurement signals, river water level signals, etc. at each drainage pumping station's equipment are collected via the monitoring system of each drainage pumping station and displayed on a screen that shows a schematic representation of the river basin and each drainage pumping station, as well as on a screen that shows a time series graph.In addition, based on conditions that combine the various signals mentioned above, operational guidance for drainage pumping station operation is displayed on the screen, providing information to the administrator in charge of centralized operation of each drainage pumping station.

[0004] Regarding operation guidance for monitoring systems and remote monitoring systems, each system pre-registers equipment status signal items, measurement signal items, predicted inflow volume (predicted value of inflow volume to drainage pumping station), etc. as standard information items to be monitored, and then, based on basic rules based on the operation standards (basic rules related to drainage pumping station operation), defines multiple operation procedures for equipment operation based on conditions that combine the signal status of each registered information item, for example, the ON / OFF status of equipment status signals, measurement value data of measurement signals, and the results of calculations between measurement value data.When the status signal status, measurement value data of measurement signals, and the results of calculations between measurement value data actually collected by each system match the conditions of any of the defined operation procedures, the corresponding operation procedure is displayed as operation guidance on the screen of each system.

[0005] [Patent Document 1] Japanese Patent Application Publication No. 8-100771 Summary of the Invention [Problem to be solved by the invention]

[0006] In operating drainage pumping stations, in addition to the information collected by monitoring systems and remote monitoring systems, it is necessary to take into account non-standard information such as weather and river information provided by the Japan Meteorological Agency and the Ministry of Land, Infrastructure, Transport and Tourism, events detected during regular equipment inspections, and temporary constraints on drainage pumping station management. However, as mentioned above, conventional monitoring and remote monitoring systems only register standard information items such as equipment status signal items, measurement signal items, and predicted inflow volume items, and display and provide operation procedures based on conditions combining the signal states of each registered information item as operation guidance. Therefore, conventional monitoring and remote monitoring systems do not define operation procedures based on conditions combining the above-mentioned non-standard information items, making it difficult to provide operation guidance.

[0007] Furthermore, weather and river information provided by the Japan Meteorological Agency and the Ministry of Land, Infrastructure, Transport and Tourism must be obtained via public networks such as the Internet. However, due to information security concerns, monitoring systems and remote monitoring systems cannot be connected to public networks such as the Internet, making it difficult for monitoring systems and remote monitoring systems to obtain this information.

[0008] Furthermore, the basic rules for operating drainage pumping stations, which are used to define operating procedures based on conditions that combine the signal states of each of the above-mentioned registered information items, did not take into account the know-how regarding drainage pumping station operation that the operators of the drainage pumping stations and the administrators of the remote monitoring systems have gained through experience, and the operating rules that are customarily followed based on that know-how.

[0009] In addition, operation guidance is displayed and provided on the system screen. However, since drainage pumping stations are facilities that are operated when rivers overflow due to heavy rain, etc., there may be situations before the drainage pumping station starts operation where the operator is not yet at the drainage pumping station and is therefore unable to check the operation guidance because he or she is not referring to the system screen. In such situations, conventional monitoring systems and remote monitoring systems have not been equipped with a means for providing operation guidance to the operator.

[0010] The present invention has been made in consideration of these problems, and aims to provide an operational support system for monitoring systems and remote monitoring systems that can acquire information provided by the Japan Meteorological Agency and the Ministry of Land, Infrastructure, Transport and Tourism, combines non-standard information including such information with the signal status for each standard information item, and generates operating procedures based on the combined conditions, taking into account not only basic rules but also the know-how of drainage pumping station operators and remote monitoring system managers, and can provide these as operation guidance. [Means for solving the problem]

[0011] The present invention includes multiple means for solving at least some of the above-mentioned problems, and an example thereof is as follows: That is, an operation support system connected to a monitoring system or remote monitoring system of a drainage pumping station via a closed network and providing operation guidance for the drainage pumping station to the monitoring system or remote monitoring system, comprising an information recording unit, a rule accumulation unit, a prompt generation unit, and an operation guidance generation unit, wherein the information recording unit records information about the drainage pumping station transmitted from the monitoring system or remote monitoring system via the closed network and meteorological information or hydrological information acquired via an external network different from the closed network, the rule accumulation unit accumulates basic rules regarding the operation of the drainage pumping station and applied rules based on the operational know-how of an operator of the drainage pumping station or an administrator of the remote monitoring system, the prompt generation unit generates prompts based on the information recorded in the information recording unit and the basic rules and applied rules accumulated in the rule accumulation unit, and the operation guidance generation unit generates operation guidance for the drainage pumping station based on the prompts. [Effects of the Invention]

[0012] According to the present invention, the operation support system for the monitoring system and remote monitoring system can take into account a wide range of information, such as meteorological information, nearby water levels, hydrological information such as rainfall, periodic equipment inspection results, and constraints related to the operation of the drainage pumping station, in addition to the conventional standard information items of equipment status signal items and measurement signal items. This makes it possible to provide operation guidance that takes into account not only the current actual status of the drainage pumping station being operated, but also the weather conditions and status of surrounding drainage pumping stations prior to the operation of the drainage pumping station, the results of upcoming periodic equipment inspections, etc., and also makes it possible to provide operation guidance to operators and managers who do not refer to the screens of the drainage pumping station monitoring system or remote monitoring system. Note that problems, configurations, and effects other than those described above will become clear from the following description of the embodiment of the invention.

[0019] A program may be installed on a computer from a program source. The program source may be, for example, a program distribution server or a computer-readable storage medium. When the program source is a program distribution server, the program distribution server may include a processor and storage resources for storing the program to be distributed, and the processor of the program distribution server may distribute the program to be distributed to other computers. In addition, in an embodiment, two or more programs may be realized as one program, or one program may be realized as two or more programs. [Example]

[0020] A drainage pumping station is a facility installed, for example, at the point where a tributary flows into a mainstream river. When the water level of the mainstream river rises due to heavy rain or other factors, threatening to backflow into the tributary, the pumping station forcibly drains the water from the tributary into the mainstream river to prevent flooding around the tributary. This pumping station, for example, includes a drainage pumping station equipped with pumping equipment and a spillway that bypasses the drainage pumping station. Typically, water from a tributary flows naturally into the mainstream river via the spillway. When heavy rain or other factors increase the amount of rainfall upstream of the mainstream river, causing the water level to rise, the pumping station closes a gate (e.g., a sluice gate) installed at the mouth of the spillway to prevent backflow of water from the mainstream river into the tributary. The pumping station then directs the water from the tributary to the drainage pumping station, where it discharges the water from the tributary into the mainstream river. An example of the configuration of such a drainage pumping station is described using Figure 1.

[0021] Figure 1 is a diagram showing an example of the configuration of a drainage pumping station and a monitoring system that supports the operation of the drainage pumping station equipment. In Figure 1, the drainage pumping station 1 is made up of a monitoring system 11, a control panel 12 to which the monitoring system 11 is connected, target equipment 13 (equipment to be monitored by the monitoring system 11) including pump equipment 3-1, gate equipment 3-2, private power generation equipment 3-3, dust removal equipment 3-4, etc. connected to the control panel 12, and measuring equipment 14, etc. also connected to the control panel 12.

[0022] The pump equipment 3-1 in the target equipment 13 is composed of, for example, a pump and a pump drive device (engine, etc.). In the above example, the gate equipment 3-2 is composed of a gravity flow gate (sluice gate) installed at the mouth of the discharge channel or a discharge gate installed at a drainage pumping station. The dust collector equipment 3-4 is a device that captures and removes dust such as leaves, branches, and driftwood from the water flowing into the drainage pumping station. The private power generation equipment 3-3 is a device that ensures power for various facilities, devices, and equipment at the drainage pumping station in the event of a power outage. Note that the pump equipment, gate equipment, dust collector equipment, and private power generation equipment may be equipped with sensors that detect status information (for example, temperature, gate opening, vibration, operating sound, etc.).

[0023] The measuring device 14 is composed of multiple measuring devices (not shown). For example, in the above example, each measuring device is installed in a tributary river, a main river, etc., and measures the water level of the tributary river (inner water level), the water level of the main river (outer water level), and the amount of rainfall upstream of both rivers.

[0024] When the operation of the drainage pumping station starts and an operation / control command is received from an operator, the control panel 12 controls the equipment that is the target of the operation / control command in the target equipment 13, thereby operating the equipment. The control panel 12 observes the status information of each piece of equipment in the target equipment 13 (for example, the operating status of the pump equipment, the open / close status of the gate equipment, etc.) and the measurement results of the measuring equipment 14 at regular time intervals.

[0025] The monitoring system 11 is composed of one or more information processing devices (PCs), such as personal computers or server devices. The PC is equipped with a display or printer (not shown) as a means for outputting and displaying information, and a keyboard, mouse, or touch panel display (not shown) as a means for inputting information. The PC also has an interface for connection with the control panel 12, an interface for connection with a remote monitoring system (described later), and an interface for connection to a closed network.

[0026] The monitoring system 11 (specifically, the PC that constitutes the monitoring system 11) is connected to a control panel 12, and the control panel 12 constantly collects and monitors the status information of each piece of equipment in the target equipment 13 that the control panel 12 observes at regular intervals, as well as measurement results from measuring instruments 14, as equipment status signals, water level signals, rainfall signals, etc., and displays the status information of each piece of equipment and each measurement result on a screen that schematically shows the drainage pumping station or a screen that shows a time-series graph, as well as operation guidance according to the state and value of each signal. The monitoring system 11 also records and saves the collected signals, etc., in the PC or in a storage device (not shown) connected to the PC.

[0027] The operator of the drainage pumping station refers to the status information of each piece of equipment, each measurement result, etc., and operation guidance displayed on the display of the monitoring system 11, and operates the operation switches, etc., provided on the control panel 12, or inputs operation and control commands using the input means of the monitoring system 11 (the monitoring system 11 outputs the operation and control commands input by the operator to the control panel 12), thereby enabling the operator of the drainage pumping station to control the operation, stopping, speed adjustment, etc. of the target equipment 13.

[0028] Fig. 2 is a diagram showing an example of the configuration of a remote monitoring system that supports the operation of facilities at multiple drainage pumping stations. In Fig. 2, the remote monitoring system 21 is composed of one or more information processing devices (PCs) such as personal computers or server devices. The PC is equipped with a display or a printer (not shown) as a means for outputting and displaying information, and a keyboard, mouse, or touch panel display (not shown) as a means for inputting information. The PC is equipped with an interface for connection to multiple monitoring systems (described later) and an interface for connection to a closed network.

[0029] The remote monitoring system 21 (specifically, a PC constituting the remote monitoring system 21) is connected to the monitoring systems of the multiple drainage pumping stations 1-1 to 1-n in the target pumping station 22 via dedicated communication lines or the like. The remote monitoring system 21 collects and monitors equipment status signals, water level signals, etc. that are constantly collected by the monitoring systems of the multiple drainage pumping stations 1-1 to 1-n during operation, and displays on a display screen a schematic representation of the river basin in which each drainage pumping station is installed and each drainage pumping station, as well as status information and measurement results of each equipment at each drainage pumping station, and operation guidance according to the state and value of each signal. The remote monitoring system 21 also records and saves the collected signals, etc., in the PC or in a storage device (not shown) connected to the PC.

[0030] The administrator of the remote monitoring system 21 refers to the status information of each piece of equipment at each drainage pumping station, each measurement result, and operation guidance displayed on the display, and inputs operation and control commands for each or all of the drainage pumping stations via input means. The remote monitoring system 21 transmits the operation and control commands input by the administrator to the target drainage pumping stations. This enables the administrator of the remote monitoring system 21 to manage and control the operation of each drainage pumping station at the target pumping station 22.

[0031] 3 is a diagram showing an example of the configuration of an operation support system for the monitoring system 11 and the remote monitoring system 21. In FIG. 3, the operation support system 31 in this embodiment is configured by a group of software installed or constructed on a cloud server 30. Specifically, the operation support system 31 is configured by an equipment management database 32, a basic rule database 33, a prompt generation unit 34, an operation procedure generation unit 35, a basic rule generation unit 36, and a guidance distribution unit 37. The operation support system 31 can generate and output operation guidance related to the operation of the drainage pumping station, etc., and provide it to relevant parties such as the operator of the drainage pumping station where the monitoring system 11 is installed, the manager of the remote monitoring system 21, or the inspector who periodically inspects each piece of equipment at the drainage pumping station.

[0032] From the viewpoint of information security, the monitoring system 11 and the remote monitoring system 21 are restricted from being connected to a public network such as the Internet. Therefore, the remote monitoring system 21 is connected to the monitoring system 11 of each drainage pumping station by a dedicated communication line or the like, rather than by a public network such as the Internet. Similarly, the monitoring system 11, except for the remote monitoring system 21, is basically connected only to each facility and device at the drainage pumping station.

[0033] Therefore, under these constraints, in this embodiment, the monitoring system 11 and the remote monitoring system 21 are provided with an interface for connecting to a closed network (not shown) and are connected to a closed network 38. The closed network 38 is a communication line separated from public networks such as the Internet, and therefore can satisfy the above-mentioned constraints. In this embodiment, the closed network 38 is, for example, a closed network for mobile phone lines operated by a telecommunications company. The monitoring system 11 and the remote monitoring system 21 are connected to the cloud server 30 via the closed network 38, and receive operation guidance output from the operation support system 31, and transmit information necessary for the operation support system 31 to generate operation guidance. The cloud server 30 also has an interface for connecting to a closed network (not shown), and is configured to be able to send and receive information (data) to and from the monitoring system 11 and the remote monitoring system 21 via the closed network 38 using this interface.

[0034] Concerning the transmission of information necessary for generating operation guidance, specifically, the monitoring system 11 transmits equipment status signals, water level signals, rainfall signals, etc. collected via the control panel 12 to the cloud server 30 each time they are collected, as described above. Basic rules (basic rules) related to the operation of the drainage pumping station based on the operation standards of the drainage pumping station are registered in advance in the monitoring system 11, and the monitoring system 11 also transmits these basic rules. Furthermore, since inspectors conduct regular equipment inspections of each piece of equipment at the drainage pumping station and the inspection result information is registered in the monitoring system 11 by the inspectors, the monitoring system 11 also transmits the inspection result information together with the above-mentioned signals.

[0035] Furthermore, the above-mentioned basic rules do not include the know-how regarding meteorological and hydrological events that require attention and operations that the operators of the drainage pumping station have acquired through experience, and the operational rules that are customarily followed based on that know-how. Therefore, the operators are required to input such know-how and operational rules in advance as text data using the input means of the monitoring system 11 and register them in the monitoring system 11, and the monitoring system 11 transmits the text data together with the above-mentioned basic rules.

[0036] Meanwhile, as described above, the remote monitoring system 21 collects equipment status signals, water level signals, rainfall signals, etc. for each drainage pumping station that are the target pumping stations monitored by the remote monitoring system 21, as well as inspection result information registered in the monitoring system of each drainage pumping station, and transmits this information to the cloud server 30 each time it is collected. Furthermore, the administrator of the remote monitoring system 21 is required to input in advance, as text data using the input means of the remote monitoring system 21, management information for the multiple drainage pumping stations that are the target pumping stations, as well as the administrator's empirical know-how regarding the operation of the multiple drainage pumping stations, including meteorological and hydrological events that require attention, and customary operating rules based on that know-how, and these are registered in the remote monitoring system 21, and the remote monitoring system 21 also transmits this text data. Note that the management information is, for example, information on whether each drainage pumping station is operational or not, and countermeasures to be taken if one of the drainage pumping stations is inoperable (such as operating another nearby drainage pumping station as an alternative), etc. This management information is registered in the remote monitoring system 21 by the administrator each time an event corresponding to the management information occurs, and is transmitted from the remote monitoring system 21 to the cloud server 30. In addition, with regard to the know-how and operation rules of the operator or administrator described above, each time new know-how or operation rules are generated, they may be registered in the monitoring system 11 or the remote monitoring system 21 by the operator or administrator and transmitted to the cloud server 30.

[0037] Equipment status signals, water level signals, etc. for each drainage pumping station, inspection result information, and management information for the monitored pumping station transmitted from each of the monitoring system 11 and the remote monitoring system 21 are received by the cloud server 30 and input into an equipment management database 32 in the operation support system 31. Meanwhile, text data relating to the basic rules of the drainage pumping station, operator know-how, and operation rules transmitted from the monitoring system 11, and text data relating to the manager's know-how and operation rules transmitted from the remote monitoring system 21 are each received by the cloud server 30 and input into a basic rule generation unit 36 ​​in the operation support system 31.

[0038] The equipment management database 32 records and manages input equipment status signals, water level signals, etc., inspection result information, and management information for the monitored plant as a schema-less database. Details of this schema-less equipment management database 32 will be explained using Fig. 4. Fig. 4 is a diagram showing an example of the configuration of the schema-less equipment management database 32 in comparison with an example of a schema-based equipment management database.

[0039] 4, in a schema-based equipment management database 41 conventionally used in the monitoring system 11 and the remote monitoring system 21, the items and formats of signals and information that can be recorded are predefined as standard information items and registered in the database. Various signals and information are entered into the database in the predefined format and recorded in the appropriate item among the registered items. For example, in the example shown in FIG. 4, the schema-based equipment management database 41 registers the standard information items "observation time," "pump operation status," "gate open / close status," "inner water level," "outer water level," and "predicted inflow volume," each with its own recording format, and records the corresponding signal for each item (e.g., pump equipment status signal, inner water level signal, etc.). In this way, the schema-based equipment management database 41 can only record signals in predefined items. Therefore, even if the monitoring system 11 and the remote monitoring system 21 collect various information related to the operation of the drainage pumping station, information that does not fit into the items and formats registered in the schema-based equipment management database 41 is not recorded at all and cannot be utilized.

[0040] On the other hand, the schema-less equipment management database 32 does not have defined (registered) items or formats of recordable information, etc., as in the schema-based equipment management database 41, and is configured to be able to record various information and signals in various formats. For example, in the example shown in Fig. 4, the schema-less equipment management database 32 records information on multiple drainage pumping stations ("Drainage Pumping Station A", "Drainage Pumping Station B"), and for each of them, in addition to signals of the same items as in the schema-based equipment management database 41 (pump equipment status signals, inland water level signals, etc.), it also records "inspection information", "management information", etc. that are not in the schema-based equipment management database 41.

[0041] Returning to the explanation of Fig. 3, cloud server 30 has an interface (not shown) and is also connected to the Internet 39 via this interface. Cloud server 30 periodically accesses the relevant websites of the Japan Meteorological Agency and the Ministry of Land, Infrastructure, Transport and Tourism via the Internet 39, and also has a function (not shown) of collecting from each website, for example, using a publicly available API (Application Programming Interface), weather information such as nationwide or regional warnings and alerts, rainfall (current and predicted), weather forecasts, typhoon occurrence information and path forecasts, and hydrological information such as rainfall, water level, flow rate, etc. for each specific point or river.

[0042] The information periodically collected by the cloud server 30 is input into the facility management database 32. The facility management database 32 records and manages the input meteorological and hydrological information in association with each drainage pumping station for each region or location. For example, in the example shown in FIG. 4, the schema-less facility management database 32 records "weather information" and "XX water level" information for a nearby river for "Drainage Pumping Station A" in the upper row. As described above, the schema-less facility management database 32 can flexibly accommodate the increase or decrease of signal items, and can record and manage information that does not necessarily occur, such as warnings in "weather information," constraint information in "management information" that requires consideration of the status of other pumping stations when managing multiple drainage pumping stations, and information that requires emergency response based on inspection result information in "inspection information." The facility management database 32 updates (adds) records each time a signal or information is input.

[0043] The basic rule generation unit 36 ​​outputs the basic rules as they are from the input text data related to the basic rules of the drainage pumping station, the operator's know-how and operational rules, and the manager's know-how and operational rules. Meanwhile, for the text data related to the operator's know-how and operational rules and the manager's know-how and operational rules, the basic rule generation unit 36 ​​extracts keywords (e.g., "location name," "water level," "rise," "exceed," etc.) that serve as conditions for rule generation from each piece of text data, and generates a new rule for each piece of text data or by combining several pieces of text data. The basic rule generation unit 36 ​​outputs one or more rules (applied rules) generated in this way. The basic rules and one or more applied rules output by the basic rule generation unit 36 ​​are input to the basic rule database 33.

[0044] The basic rule database 33 records and manages the input basic rules and one or more applied rules as a schema-less database. Details of this schema-less basic rule database 33 will be described with reference to FIG. 5. FIG. 5 is a diagram showing an example of the configuration of the schema-less basic rule database 33. In FIG. 5, the schema-less basic rule database 33 records a mixture of conventional basic rules and applied rules. The basic rule generation unit 36 ​​generates rules related to the operation of drainage pumping stations based on various conditions for various signals and information (e.g., meteorological or hydrological events that require attention, cooperation with nearby drainage pumping stations, etc.) without being bound by the condition items in the basic rules (the fixed information items described above). Therefore, the basic rule database 33 is configured as a schema-less database in order to record and manage such applied rules.

[0045] In the example shown in FIG. 5 , the basic rule database 33 stores, for example, a basic rule that, regarding gate closure, all of the following conditions must be met: “the pump is stopped,” “the gate is fully open,” “the external water level exceeds a specified water level,” and “the external water level exceeds an internal water level.” Similarly, regarding pump operation, the database stores a rule that all of the following conditions must be met: “the pump is stopped,” “the gate is fully closed,” “the internal water level (inlet water level) exceeds a specified water level,” and “the external water level (discharge water level) exceeds a specified water level.” Furthermore, as an applied rule, regarding preparation for station operation, the database stores a rule that any of the following conditions must be met: “a forecast of a typhoon landing,” “a river water level warning,” “rainfall forecast,” and “information on inspection results of a nearby station.” The basic rule database 33 records and accumulates basic rules and applied rules each time they are input.

[0046] The prompt generation unit 34 generates a prompt (a character string indicating the content to be generated (text data such as a question)) for generating an operating procedure that is output as operating guidance by the operating procedure generation unit 35 described later. The prompt generation unit 34 constantly refers to each signal and each piece of information recorded in the equipment management database 32 and each rule stored in the basic rule database 33. When any of the signals or pieces of information recorded in the equipment management database 32 meets the conditions of any of the rules stored in the basic rule database 33, the prompt generation unit 34 generates and outputs a prompt based on the content of each signal and each piece of information recorded in the equipment management database 32, including the met signal or piece of information, and the rules (either basic rules or applied rules, or both) related to those signals and information. The prompt output by the prompt generation unit 34 is input to the operating procedure generation unit 35.

[0047] The operating procedure generator 35 is a generative AI, a type of deep learning model based on a recurrent neural network. Specifically, it employs an LSTM (Long Short-Term Memory)-based generative model. This generative model is pre-trained using a large text dataset to learn text patterns and structures, and is tuned to improve the quality and relevance of the generated text through appropriate hyperparameter settings and training methods. The generative model is capable of performing natural language processing tasks and predicting the next text sequence based on the text data provided as input.

[0048] The operation procedure generation unit 35 in this embodiment is configured to train such a generation model on, for example, the operation standards of the drainage pumping station, basic rules based on the operation standards, multiple operation procedures for equipment operation defined based on conditions combining the states of various signals collected by the monitoring system 11 and the remote monitoring system 21, measurement data, calculation results between measurement data, etc., the weather and hydrological events that operators and managers have experientially known as warning signs and operation know-how and the customary operation rules based on that know-how, the states of various signals, measurement data, calculation results between measurement data, etc. when the monitoring system 11 and the remote monitoring system 21 were operated in the past, equipment inspection result information, management information, weather information, hydrological information, operation guidance provided by the monitoring system 11 and the remote monitoring system 21, actual operation results (operation details), etc., as well as each signal and information stored in the equipment management database 32 at the time of learning, and the rules stored in the basic rule database 33.

[0049] The operating procedure generation unit 35 configured in this manner performs inference based on the prompt input from the prompt generation unit 34, generates text data relating to the operating procedure as the inference result, and outputs it as operation guidance. Specific examples of prompts generated by the prompt generation unit 34 and inferences made by the operating procedure generation unit 35 based on those prompts are shown below.

[0050] First, based on the equipment status signals, water level signals, etc., inspection result information, management information, weather information, and hydrological information for each drainage pumping station at that time recorded in the above-mentioned equipment management database 32, the prompt generation unit 34 generates text data such as: (1) the pumps at drainage pumping station B are normal; (2) the sluice gates are fully open and the inlet and outlet water levels are both 0.5 m because the typhoon has not yet affected the area; (3) a heavy rain warning is expected to be issued due to the approaching typhoon; and (4) drainage pumping station A requires maintenance as a result of an emergency inspection and cannot be operated. In addition, based on the rules recorded in the basic rule database, the prompt generation unit 34 generates the following text data: (5) The pump operates when the inflow water level is 2 m or more; (6) The sluice gate closes fully when the discharge water level is 1 m or more; (7) When the sluice gate is fully open, the inflow water level and the discharge water level are the same; (8) The pump operates when the pump is normal; (9) If the hourly rainfall is 20 mm, there is a high possibility that the inflow water level will rise by 1.5 m after 6 hours; (10) If a heavy rain warning is issued, the hourly rainfall will exceed 20 mm; (11) If drainage pumping station A cannot be operated, two pumps at drainage pumping station B will be operated; and combines both text data to generate and output a prompt that instructs the operation procedure generation unit 35 to generate an operation procedure.

[0051] The operating procedure generating unit 35 performs inference regarding the operating procedure based on the prompt input from the prompt generating unit 34. Specifically, the inference performed by the operating procedure generating unit 35 is as follows.

[0052] "Drainage pumping station A is not operational, but the pumps at drainage pumping station B are normal. ⇒If a heavy rain warning is issued due to an approaching typhoon, the inflow water level will rise in six hours, so the pump at drainage pumping station B will need to be operated. ⇒ The current inflow water level is 0.5m and the pump is not yet running, but it may reach 2m or more in 6 hours. Therefore, if a heavy rain warning is issued, the pump will need to start operating in 6 hours. ⇒At the same time, the floodgates must also be closed when the inflow water level exceeds 1m. This makes drainage more efficient and reduces flood damage. Therefore, if a typhoon approaches, the two pumps at Pumping Station B must be operated and the floodgates must be closed six hours later. The operation procedure generation unit 35 outputs the text data related to the operation procedure generated by the above-described inference as operation guidance from the operation procedure generation unit 35. The cloud server 30 transmits the operation guidance output from the operation procedure generation unit 35 to the monitoring system 11 and the remote monitoring system 21 via the closed network 38 as shown in FIG.

[0053] The monitoring system 11 and the remote monitoring system 21 each receive the operation guidance transmitted from the cloud server 30. In each system, the received operation guidance is displayed in a dialog format on a display, and operation procedures are shown to an operator or a manager.

[0054] Meanwhile, the operation guidance output from the operation procedure generation unit 35 is input to the guidance distribution unit 37. The guidance distribution unit 37 pre-registers destination address data for operators of each drainage pumping station, managers of the remote monitoring system 21, and other relevant parties, as well as the distribution method and destination for each. The relevant parties include, for example, inspectors who periodically inspect the equipment at the drainage pumping station, maintenance personnel who perform maintenance and repairs on the equipment, and personnel from manufacturers of the equipment. The distribution method is, for example, email or SMS (Short Message Service). The destinations are information devices such as smartphones, tablet terminals, and dedicated devices. The destination address data and other data may be registered in the guidance distribution unit 37 by inputting them into the guidance distribution unit 37 using an information input means for the cloud server 30. Alternatively, the destination address data and other data transmitted from the monitoring system 11 or the remote monitoring system 21 may be received by the cloud server 30 and input to the guidance distribution unit 37.

[0055] The guidance distribution unit 37 extracts text data related to the operation procedures of each piece of equipment at each pumping station from the received text data related to the operation procedures, and adds the pre-registered destination address data of the operator to the extracted text data to generate a guidance message for the operator. Similarly, if the received text data related to the operation procedures contains a text portion related to the operation and management of the monitored pumping station, the guidance distribution unit 37 extracts the text portion and adds the pre-registered destination address data of the manager to the extracted text data to generate a guidance message for the manager. Similarly, if the received text data related to the operation procedures contains a text portion related to the status and maintenance of each piece of equipment at each pumping station, the guidance distribution unit 37 extracts the text portion and adds the pre-registered destination address data of the relevant person to generate a guidance message for the relevant person. The guidance distribution unit 37 outputs each of one or more guidance messages as a message to the registered destination in the format of the registered distribution method.

[0056] The cloud server 30 transmits one or more guidance messages output from the guidance distribution unit 37 via the Internet 39 to information devices (distribution destinations) owned by the operators of the drainage pumping station, the administrator of the remote monitoring system 21, and each relevant party.

[0057] The information devices of the destination operators, managers, and other related parties receive the guidance message in the form of the above-mentioned delivery method, i.e., email or SMS, and display it on their screens. This allows the operation procedures and operation / management information to be presented to operators and managers who are not monitoring or referring to (or are unable to refer to) the operation guidance displayed on the displays of the monitoring system 11 and remote monitoring system 21, and also provides information on the maintenance of each piece of equipment, etc. to each related party, and calls attention to the operation of each drainage pumping station.

[0058] In the above description of the present embodiment, the prompt generator 34 generates and outputs a prompt when any of the signals or information recorded in the equipment management database 32 satisfies any of the conditions of the rules stored in the basic rule database 33. However, even before the monitoring system 11 or the remote monitoring system 21 starts operation and no equipment status signals or management information are transmitted from each system, the prompt may be generated and output when, for example, meteorological information or hydrological information collected by the cloud server 30 and recorded in the equipment management database 32 satisfies any of the conditions of the rules stored in the basic rule database 33. In this case, the operating procedure generator 35 also generates and outputs operation guidance based on the prompt. The guidance distributor 37 generates and outputs guidance messages for distribution destinations, such as operators, from the operation guidance input by the operating procedure generator 35. This makes it possible to present guidance messages to operators and the like, and to draw their attention to the operation of each drainage pumping station and encourage them to start operation before the monitoring system 11 and the remote monitoring system 21 start operation.

[0059] Furthermore, it has been explained that the guidance distribution unit 37 extracts the text portion related to each operator, etc. from the text data received as operation guidance, adds pre-registered destination address data to create a guidance message, and outputs each guidance message as a message to the destination in the format of the registered distribution method, but the monitoring system 11 and the remote monitoring system 21 may also be equipped with such a function.

[0060] Specifically, destination address data of operators and related parties of the drainage pumping station is registered in advance in the monitoring system 11, and destination address data of managers and the like is registered in the remote monitoring system 21. The monitoring system 11 extracts text portions relating to the operation procedures of each piece of equipment at the drainage pumping station where the monitoring system 11 is installed from the text data relating to the operation procedures received as operation guidance, and adds the destination address data of the operators registered in advance to the extracted text data. Similarly, if there is a text portion relating to the status or maintenance of each piece of equipment from the received text data relating to the operation procedures, the monitoring system 11 extracts that text portion and adds the destination address data of related parties registered in advance. The monitoring system 11 transmits one or more pieces of text data with the destination address data added in this way to the cloud server 30 as guidance messages.

[0061] Similarly, if the text data relating to the operation procedures received as operation guidance contains a text portion relating to the operation and management of the monitored plant, the remote monitoring system 21 extracts the text portion and adds the destination address data of the manager, which has been registered in advance, to the extracted text data. Similarly, if the text data relating to the operation procedures received contains a text portion relating to a related person, which has been registered in advance, the remote monitoring system 21 extracts the text portion and adds the destination address data of the related person. The remote monitoring system 21 transmits one or more pieces of text data to which the destination address data has been added as a guidance message to the cloud server 30. The guidance messages are received by the cloud server 30 and input to the guidance distribution unit 37 in the operation support system 31. The guidance distribution unit 37 determines the distribution method and destination for each of the one or more input guidance messages and outputs them as messages addressed to the destinations in the format of the determined distribution method.

[0062] In this way, by providing the monitoring system 11 and the remote monitoring system 21 with the function of creating a guidance message, it becomes possible to freely change or add destination operators, etc.

[0063] Furthermore, although the monitoring system 11 has been described as transmitting equipment status signals, water level signals, rainfall signals, and the like collected via the control panel 12 to the cloud server 30, the monitoring system 11 may also collect status information detected by sensors installed in each piece of equipment via the control panel 12 and transmit it to the cloud server 30. In this case, the status information is recorded in the equipment management database 32, and if any of the conditions of the rules recorded in the basic rule database 33 (e.g., threshold conditions for each piece of status information) is met, a prompt is generated and output by the prompt generation unit 34, a response procedure is generated and output by the operation procedure generation unit 35, and a guidance message regarding the response procedure is transmitted from the guidance distribution unit to a distribution destination of the relevant person via the monitoring system 11, etc., and presented to the relevant person. This enables the relevant person to perform maintenance, etc. of the relevant equipment based on the presented response procedure, etc., before a breakdown, etc., occurs in the relevant equipment.

[0064] Furthermore, although the operation support system 31 in this embodiment has been described as an independent system from the monitoring system 11 and the remote monitoring system 21, it may be a system (for example, an operation guidance providing unit) that executes the operation guidance providing function as part of the configuration of the monitoring system 11 or the remote monitoring system 21. In this case, the operation guidance providing unit that is part of the configuration of the monitoring system 11 or the remote monitoring system 21 is connected to a PC in the monitoring system 11 or the remote monitoring system 21 via a closed network (specifically, is constructed in a cloud server 30 connected to the closed network), and this operation guidance providing unit determines the operation procedure and outputs (displays) the operation guidance, which have conventionally been performed inside the monitoring system or the remote monitoring system.

[0065] As described above, the operation support system for the monitoring system and remote monitoring system of this embodiment records and manages not only the standard information items such as signals collected and monitored by conventional monitoring systems and remote monitoring systems, but also inspection result information, management information for the target pumping station, meteorological information, hydrological information, etc., and can record and accumulate basic rules based on the drainage pumping station's operation standards, as well as rules generated based on the operational know-how and operational rules acquired through the experience of operators and managers. Furthermore, an operation procedure generator that learns various information related to the operation of the drainage pumping station, various signals, information, etc. from past operations, and operational performance, etc., can be used to infer operation procedures and generate operation guidance based on the various recorded information and accumulated rules. Furthermore, the generated operation guidance can be displayed on the monitoring system and remote monitoring system, and related information in the operation guidance can be transmitted to and displayed on information devices owned by operators, managers, relevant parties, etc., to alert them to the operation of the drainage pumping station.

For example, the above-described exemplary embodiments have been described in detail to facilitate understanding of the present invention, and the present invention is not limited to those including all of the components described herein.

Furthermore, the control lines and information lines in the figures are only those considered necessary for explanation, and not necessarily all are shown. It is also possible to consider that almost all components are interconnected.
