In the sensor device 10, a member for measuring water quality is housed in a housing 11. A lid 12 that can be opened and closed is attached to the housing 11.

The housing 11 has a substantially rectangular parallelepiped shape with one open surface. On one side surface (first side surface) of the housing 11, a pipe connection hole 11a for draining the sample water, a pipe connection hole 11b for supplying the sample water, and a pipe connection hole for power input and signal output are provided. 11c (three in the example of FIG. 3) and an intake port 11d are formed. An exhaust port 11e (not shown) is formed on a side surface (second side surface) facing the first side surface of the housing 11.

A valve 1110 is attached to the pipe connection hole 11a. A valve 119 is attached to the pipe connection hole 11b. An air filter 1118 is attached to the intake port 11d.

Inside the housing 11, various sensors 111 to 118, flow cells 1111, control box 1112, terminal block 1113 for power input, terminal block 1114 for external output, air bleeding valve 1115, drain valve 1116, and flow control valve 1117 is stored.

The various sensors 111 to 118 include, for example, a sensor for measuring electrical conductivity (hereinafter referred to as an EC sensor) 111 including an electrical conductivity cell. The various sensors 111 to 118 include, for example, a sensor for measuring residual chlorine (hereinafter referred to as an FCL sensor) 112 for measuring the chlorine concentration. The various sensors 111 to 118 include, for example, a pH measuring sensor (hereinafter referred to as a pH sensor) 113 provided with electrodes (reference electrode and comparative electrode) for measuring pH. The various sensors 111 to 118 include, for example, a sensor for measuring the oxidation-reduction potential (hereinafter referred to as an ORP sensor) 114 including an electrode (reference electrode and a comparison electrode) for measuring the oxidation-reduction potential. The various sensors 111 to 118 include, for example, a sensor for measuring nitrate ion (hereinafter referred to as NO3 sensor) 115 for measuring nitrate ion. The various sensors 111 to 118 include, for example, a sensor (hereinafter referred to as a FLOW sensor) 116 for measuring the flow rate of water flowing into the sensor device 10. The various sensors 111 to 118 include, for example, a sensor (hereinafter referred to as a TUR sensor) 117 for measuring the turbidity of water flowing into the sensor device 10. The various sensors 111 to 118 include, for example, a sensor (hereinafter referred to as a TEMP sensor) 118 for measuring the temperature of water flowing into the sensor device 10.

The various sensors used in the sensor device 10 are not limited to these. For example, a sensor for measuring other items may be mounted in place of any of the EC sensor 111, the FCL sensor 112, the pH sensor 113, the ORP sensor 114, and the NO3 sensor 115. Further, for example, any one of the EC sensor 111, the FCL sensor 112, the pH sensor 113, the ORP sensor 114, and the NO3 sensor 115 may not be mounted. Further, for example, in addition to the EC sensor 111, the FCL sensor 112, the pH sensor 113, the ORP sensor 114, and the NO3 sensor 115, a sensor for measuring other items may be mounted. At this time, for example, the flow cell 1111 may be added according to the increase in the number of sensors. The expansion of the flow cell 1111 may be dealt with, for example, by increasing the capacity of the housing 11.

For example, sensors 111-115 may sense at least one of those listed below. In addition to the above sensors, a sensor that senses at least one of the sensors listed below may be provided.
(1) Alkaliality, ion concentration, hardness (2) Chromaticity, viscosity, dissolved oxygen (3) Odor, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, total nitrogen, total phosphorus, total organic carbon, total inorganic Carbon / total trihalomethane (4) Microbial sensor detection result, chemical oxygen demand, biological oxygen demand (5) Cyan, mercury, oil, surfactant (6) Optical sensor detection result, TDS (Total Dissolved) Solids) Sensor detection results (7) Mass analysis results, fine particles, zeta potential, surface potential

The sensors 111 to 115 and 118 are detachably housed in the flow cell 1111. Here, with reference to FIG. 4, for example, the shape of the NO3 sensor 115 will be described. The shapes of the sensors 111 to 114 and 118 are the same as the shapes of the NO3 sensor 115.

The NO3 sensor 115 has a grip portion 115a, a flange portion 115b, and a measuring portion 115c. The grip portion 115a is a region that protrudes from the flow cell 1111 when the NO3 sensor 115 is mounted on the flow cell 1111. The grip portion 115a is formed in a shape that is easy for the user to grip, for example. A cord for power supply and data transmission is connected to the top of the grip portion 115a.

The flange portion 115b is a region that serves as a stopper when the NO3 sensor 115 is inserted into the flow cell 1111. A groove for functioning as a screw is formed in a part of the flange portion 115b on the measurement portion 115c side.

The measuring unit 115c is an area in which a member for measuring water quality is stored. The measuring unit 115c is inserted into the measuring port 11112 formed in the flow cell 1111. The outer diameter of the measuring unit 115c is smaller than the inner diameter of the measuring port 11112.

The flow cell 1111 is a member for bringing the sample water into contact with the measuring portions of the sensors 111 to 115 and 118 and causing the sensors 111 to 115 and 118 to accurately measure the water quality. In the present embodiment, the flow cell 1111-1 is formed so as to be able to accommodate the sensors 111 to 113. The flow cell 1111-2 is formed so as to accommodate the sensors 114, 115, 118. In this embodiment, the flow cells 1111-1 and 1111-2 are described so as to be capable of accommodating three sensors each. However, the flow cell may be configured to accommodate three or more or less than three sensors.

Here, with reference to FIG. 4, for example, the shape of the flow cell 1111-2 will be described. The shape of the flow cell 1111-1 is the same as the shape of the flow cell 1111-2. The flow cell 1111-2 is formed so that the grip portions of the sensors 114, 115, and 118 face toward the opening of the housing 11. The flow cell 1111-2 is formed so that the grip portions of the sensors 114, 115, and 118 face upward. This makes it easier for the user using the sensor device 10 to accommodate and remove the sensors 114, 115, 118. Further, it is possible to prevent water from leaking from the flow cell 1111-2 when the sensors 114, 115, and 118 are removed.

Inside the flow cell 1111-2, measurement ports 11111, 11112, 11113, a sample water supply passage 11114, and an air bleeding passage 11115 are formed. Here, with reference to FIG. 4, for example, the shape of the measuring port 11112 will be described. The shapes of the measurement ports 11111 and 11113 are the same as the shapes of the measurement ports 11112.

The measurement port 11112 has a first cylindrical portion 11112a and a second cylindrical portion 11112b. The first cylindrical portion 11112a is formed so as to open at a predetermined angle toward the front surface of the housing 11. The inner diameter of the first cylindrical portion 11112a is formed to be substantially the same as the outer diameter of the flange portion 115b of the NO3 sensor 115. A groove is formed along the circumferential direction on the inner wall of the first cylindrical portion 11112a. The groove can be fixed to the measurement port 11112 by engaging with the groove formed in the flange portion 115b.

The second cylindrical portion 11112b is formed from the bottom of the first cylindrical portion 11112a in the same direction as the first cylindrical portion 11112a. The inner diameter of the second cylindrical portion 11112b is smaller than the inner diameter of the first cylindrical portion 11112a. The inner diameter of the second cylindrical portion 11112b is slightly larger than the outer diameter of the measuring portion 115c of the NO3 sensor 115.

The second cylindrical portion 11112b intersects the water supply channel 11114 in the vicinity of the bottom of the second cylindrical portion 11112b. The second cylindrical portion 11112b intersects the air bleeding passage 11115 at a position in front of the water supply passage 11114 in the opening direction. The water supply channel 11114 intersects the second cylindrical portion 11112b on the back surface side of the flow cell 1111-2 with respect to the air bleeding path 11115. Further, the water supply passage 11114 intersects with the second cylindrical portion 11112b at a position higher than the air bleeding passage 11115.

The second cylindrical portion 11113b of the measurement port 11113 has a hole 11113c formed at the bottom thereof. A joint 1122 is installed in the hole 11113c. The joint 1122 is connected to, for example, the drain valve 1116 by a hose.

The water supply channel 11114 is formed so as to penetrate the flow cell 1111-2 in the vertical direction. A joint 1120 is installed at the upper end of the water supply channel 11114. The joint 1120 is connected, for example, by a hose to the joint 1121 installed at the lower end of the water supply channel 11114 of the flow cell 1111-1. A joint 1121 is installed at the lower end of the water supply channel 11114. The joint 1121 is connected to, for example, the pipe connection hole 11a and the drain valve 1116 by a hose.

The air bleeding path 11115 is formed so as to pass through the flow cell 1111-2 upward with the measurement port 11113 as the lower end. An air bleeding valve 1115 is installed at the upper end of the air bleeding path 11115. The air bleeding valve 1115 can be opened and closed by operating the knob.

The FLOW sensor 116 is connected to the pipe connection hole 11b via the flow rate adjusting valve 1117. The flow rate is increased or decreased by turning the flow rate adjusting knob provided on the flow rate adjusting valve 1117. The FLOW sensor 116 measures the flow rate of the sample water supplied from the pipe connection hole 11b.

The TUR sensor 117 is inserted in the shell 1171. The shell 1171 is filled with sample water supplied from the FLOW sensor 116. The sample water that has passed through the shell 1171 is supplied to the joint 1120 provided above the flow cell 1111-1.

Sample water is supplied to the sensors 111 to 118 by the piping system shown in FIG.

The control box 1112 controls the power supply and various operations in the sensor device 10. The control box 1112 transmits data to, for example, a breaker switch, a connector for connecting to various sensors, a connector for connecting to a communication IF, a fan for cooling the CPU, various sensors 111 to 118, or various sensors 111 to. It includes a connection board for receiving data from 118, a board for mounting a CPU, and the like.

A touch panel 1119 is installed on the lid 12. The touch panel 1119 includes, for example, a touch-sensitive device 11191 and a display 11192. The touch-sensitive device 11191 is an example of an input device for a user who operates the sensor device 10 to instruct or input information. The touch-sensitive device 11191 receives an instruction when the user touches the operation surface, receives an input from the user, and outputs the input received from the user to the control box 1112. The display 141 is an example of an output device that displays data according to the control of the control box 1112. The display 141 is realized by, for example, an LCD (Liquid Crystal Display), an organic EL (Electro-Luminescence) display, or the like.

As shown in FIG. 6, the sensor device 10 includes a communication unit 120, a touch panel 1119, various sensors 111 to 118, a storage unit 180, and a control unit 190. The sensor device 10 may have a position information sensor so as to automatically detect the position where the own device is installed. The position information sensor is, for example, a GPS (Global Positioning System) module. Further, the position information sensor may detect the current position of the sensor device 10 from the position of the radio base station to which the sensor device 10 is connected.

The communication unit 120 performs processing such as modulation / demodulation processing for the sensor device 10 to communicate with another device. The communication unit 120 performs transmission processing on the signal generated by the control unit 190, and transmits the signal to the outside (for example, the server 20). The communication unit 120 performs reception processing on the signal received from the outside and outputs the signal to the control unit 190.

The touch-sensitive device 11191 provided on the touch panel 1119 is an example of an input device. The input device may be realized by, for example, a keyboard, a mouse, or the like. The input device may be realized by a microphone, for example, so as to correspond to a voice input from a user. The microphone receives the voice input and gives the voice signal corresponding to the voice input to the control unit 190. The input device may include, for example, a receive port that receives an electrical signal input from an external input device.

The display 11192 provided on the touch panel 1119 is an example of an output device. The display 11192 displays data according to the control of the control unit 190. The output device is a device for presenting information to a user who operates the sensor device 10. The output device may be realized by a speaker, for example, so as to correspond to the output by voice to the user. The speaker converts the voice signal given from the control unit 190 into voice and outputs the voice to the outside of the sensor device 10.

The storage unit 180 stores data, programs, and the like used by the sensor device 10. The storage unit 180 stores, for example, calibration information 181 and measurement information 182, other sensor measurement information 183, calibration measurement information 184, and learned model 185.

The calibration information 181 stores information regarding calibration of the EC sensor 111, the FCL sensor 112, the pH sensor 113, the ORP sensor 114, the NO3 sensor 115, and the TUR sensor 117. The calibration information 181 stores, for example, information regarding calibration of the EC sensor 111, the FCL sensor 112, the pH sensor 113, the ORP sensor 114, the NO3 sensor 115, or the TUR sensor 117 transmitted from the server 20. The calibration information 181 may store, for example, information obtained as a result of calibration performed on the EC sensor 111, the FCL sensor 112, the pH sensor 113, the ORP sensor 114, the NO3 sensor 115, or the TUR sensor 117. The calibration information 181 may read and store calibration-related information stored in, for example, the EC sensor 111, the FCL sensor 112, the pH sensor 113, the ORP sensor 114, the NO3 sensor 115, or the TUR sensor 117.
In the present embodiment, the information regarding calibration includes, for example, a reference value when calculating a numerical value, a correction value when calculating a numerical value, and the like.

The measurement information 182 stores the information obtained by the measurement. The information obtained by the measurement includes, for example, the first measurement data, the second measurement data, and the third measurement data.

The first measurement data represents data measured by, for example, the measurement mechanism of the EC sensor 111, the FCL sensor 112, the pH sensor 113, the ORP sensor 114, the NO3 sensor 115, the FLOW sensor 116, the TUR sensor 117, or the TEMP sensor 118. ..

The second measurement data represents, for example, the data in which the first measurement data measured by each measurement mechanism is corrected by the trained model stored in the sensor.

Specifically, for example, the first measurement data measured by the measurement mechanism of the EC sensor 111 is corrected by the trained model stored in the EC sensor 111 to become the second measurement data. Further, for example, the first measurement data measured by the measurement mechanism of the FCL sensor 112 is corrected by the trained model stored in the FCL sensor 112 to become the second measurement data. Further, for example, the first measurement data measured by the measurement mechanism of the pH sensor 113 is corrected by the trained model stored in the pH sensor 113 to become the second measurement data. Further, for example, the first measurement data measured by the measurement mechanism of the ORP sensor 114 is corrected by the trained model stored in the ORP sensor 114 to become the second measurement data. Further, for example, the first measurement data measured by the measurement mechanism of the NO3 sensor 115 is corrected by the trained model stored in the NO3 sensor 115 to become the second measurement data. Further, for example, the first measurement data measured by the measurement mechanism of the FLOW sensor 116 is corrected by the trained model stored in the FLOW sensor 116 to become the second measurement data. Further, for example, the first measurement data measured by the measurement mechanism of the TUR sensor 117 is corrected by the trained model stored in the TUR sensor 117 to become the second measurement data. Further, for example, the first measurement data measured by the measurement mechanism of the TEMP sensor 118 is corrected by the trained model stored in the TEMP sensor 118 to become the second measurement data.

The third measurement data represents data calculated from the second measurement data output from each sensor and the information related to the calibration corresponding to each sensor. For example, the third measurement data represents an EC value for the EC sensor 111. The third measurement data represents the FCL value for the FCL sensor 112. The third measurement data represents the pH value for the pH sensor 113. The third measurement data represents the ORP value for the ORP sensor 114. The third measurement data represents the nitrate concentration for the NO3 sensor 115. The third measurement data represents turbidity for the TUR sensor 117. For sensors without calibration information, for example, there is no third measurement data.

The other sensor measurement information 183 stores, for example, information obtained by the measurement of another sensor device 10 that measures water from the same water source. The other sensor device 10 that measures water from the same water source can be rephrased as another sensor device 10 installed at different positions in the same water treatment facility.

The calibration measurement information 184 stores the information measured when the sensor is subjected to the calibration process. Specifically, for example, the calibration measurement information 184 is information measured when the EC sensor 111, the FCL sensor 112, the pH sensor 113, the ORP sensor 114, the NO3 sensor 115, and the TUR sensor 117 are subjected to calibration processing. Remember.

The trained model 185 is a model generated by, for example, causing a machine learning model to perform machine learning on the server 20 according to a model learning program. The trained model 185 is, for example, a parameterized synthesis function in which a plurality of functions are synthesized to perform a predetermined inference based on the input data. A parameterized composition function is defined by a combination of multiple adjustable functions and parameters. The trained model according to the present embodiment may be a synthetic function with any parameter that satisfies the above requirements.

For example, when the trained model 185 is generated using a forward propagation multi-layered network, the parameterized composition function may be, for example, a linear relationship between layers using a weight matrix, a nonlinear function using an activation function at each layer. It is defined as a combination of relations (or linear relations) and biases. Weighted matrices and biases are called multi-layered network parameters. A composite function with parameters changes its form as a function depending on how the parameters are selected. In a multi-layered network, by appropriately setting the parameters to be configured, it is possible to define a function capable of outputting a preferable result from the output layer.

As the multi-layered network according to the present embodiment, for example, a deep neural network (DNN), which is a multi-layered neural network targeted for deep learning, can be used. As the DNN, for example, a recurrent neural network (RNN) for targeting time-series information or the like may be used.

The trained model 185 is, for example, a model that outputs whether or not a sensor in which an abnormality has occurred is included in the sensor that has acquired the information when the information obtained by the measurement is input. Specifically, the trained model 185 is, for example, a model that outputs whether or not the sensor that measures the information is out of order when the information obtained by the measurement is input.

The presence or absence of a failure may be learned as correct output data. A facility having the same water source means, for example, the same water treatment facility.

When a sensor fails, only the measured value of that sensor changes drastically and greatly. Then, the value that has changed significantly continues to be measured. According to the trained model 185, it is possible to grasp such a tendency and detect a sensor in which a failure has occurred.

The trained model 185 uses, for example, a plurality of measured values acquired in a predetermined cycle by a plurality of sensor devices 10 installed in facilities having the same water source as input data, and is generated in one of the sensors of the sensor device 10. The presence or absence of deviation from the time of calibration may be learned as correct output data.

When the deviation from the time of calibration occurs, the difference between the measured value of the sensor and the measured value of other sensors gradually changes. According to the trained model 185, it is possible to grasp such a tendency and detect a sensor in which a deviation from the calibration time has occurred.

The trained model 185 may be trained in combination with at least one of the above contents.

The trained model 185 also refers to the newly accumulated data, for example, and is retrained on the server 20.

The batch calibration of the sensors 111 to 115 is performed, for example, by filling the flow cell 1111 with each of the three types of calibration solutions. The first calibration liquid is, for example, ultrapure water for grasping the baseline. The second calibration liquid is, for example, a liquid containing components of an optical system. The third calibration liquid is, for example, a liquid containing a component that causes a chemical effect.

In the calibration process, in the measurement using the calibration solution, if the measured value is within a predetermined range for a preset period, it is determined that the calibration process is successful. However, with this specification, it takes time from the start to the end of calibration. The calibration unit 194 according to the present embodiment stores the transition until the measured value falls within a predetermined range in each sensor based on the past measurement record. The calibration unit 194 estimates whether or not the calibration process was successful by comparing the stored transition with the transition of the measured value. The calibration unit 194 may use a trained model trained to input the transition of the measured value and output whether or not the calibration process is successful.

For example, the analysis module 2034 analyzes water treatment using the first trained model 2027, which is not the latest version, for water treatment facilities with a free contract. The first trained model 2027 that is not the latest version represents, for example, the first trained model 2027 that is a few generations ago from the latest version that is open to use. Also, for example, the analysis module 2034 analyzes water treatment using the latest version of the first trained model 2027 for water treatment facilities with paid or premium contracts.

<3 operation>
The operation of the sensor device 10 and the server 20 provided in the system 1 will be described.

<3.1 Operation of sensor device 10)
First, the user of the sensor device 10 prepares for operation. Specifically, the user confirms that the wiring and piping of the sensor device 10 are correct. The user turns on the breaker switch provided in the control box 1112. The user confirms that the air bleed valve 1115 is closed. The user opens valves 119 and 1110 to introduce the sample water into the sensor device 10. As a result, the sample water is supplied from the valve 119, and the flow cell 1111 and the shell 1171 are filled with the sample water.

The user turns the flow rate adjustment knob provided on the flow rate adjustment valve 1117 while checking the flow rate measured by the FLOW sensor 116 on the touch panel 1119. The user adjusts the flow rate of the sample water by turning the flow rate adjustment knob.

The user inserts the air bleeding tube into the insertion port 11151 provided at the upper part of the air bleeding valve 1115. The user opens the air bleeding valve 1115 to bleed air. The measurement ports 11111, 11112, 11113 of the flow cell 1111 are formed so that the openings face upward, and the air vent path 11115 is provided in the vicinity of the openings, so that the air in the measurement ports 11111, 11112, 11113 can be removed. It is possible to pull out all at once. Upon bleeding air, the user closes the air bleed valve 1115.

Information regarding calibration of the EC sensor 111, the FCL sensor 112, the pH sensor 113, the ORP sensor 114, the NO3 sensor 115, and the TUR sensor 117 attached to the sensor device 10 is stored in, for example, the storage unit 180. The sensor device 10 measures the sample water by using the information stored in the storage unit 180.

Information regarding calibration of the EC sensor 111, the FCL sensor 112, the pH sensor 113, the ORP sensor 114, the NO3 sensor 115, and the TUR sensor 117 may be written in advance in the memory of each sensor. The control unit 190 receives the calibration information stored in each sensor by the second transmission / reception unit 193. The control unit 190 stores the received information in the storage unit 180. At the time of sensor replacement, the second transmission / reception unit 193 may receive information on calibration stored in each sensor.

When the information regarding calibration is provided from the server 20, the storage unit 180 of the sensor device 10 and the memory of each sensor may not store the information regarding calibration. The user inputs an instruction to the sensor device 10 to inquire the server 20 for information on calibration.

(Acquisition of information on calibration)
FIG. 15 is a diagram illustrating an example of an operation in which the sensor device 10 shown in FIG. 1 acquires information regarding calibration from the server 20.

The first transmission / reception unit 192 of the control unit 190 inquires of the server 20 for information regarding calibration (step S11). Specifically, the first transmission / reception unit 192 determines whether or not there is information regarding calibration of, for example, the EC sensor 111, the FCL sensor 112, the pH sensor 113, the ORP sensor 114, the NO3 sensor 115, or the TUR sensor 117. Contact 20.

The control unit 203 of the server 20 confirms by the calibration setting module 2036 whether or not there is information to be transmitted to the sensor device 10 for the inquired sensor device 10 (step S12). For example, the storage unit 202 of the server 20 stores information on calibration of the EC sensor 111, the FCL sensor 112, the pH sensor 113, the ORP sensor 114, the NO3 sensor 115, and the TUR sensor 117 of the sensor device 10. The calibration setting module 2036 determines that there is information to be transmitted to the sensor device 10, and reads out the information related to calibration from the calibration table 2025 of the storage unit 202 (step S13). The server 20 transmits the read information to the sensor device 10 by the transmission control module 2032 (step S14).

The first transmission / reception unit 192 of the control unit 190 receives the information transmitted from the server 20, and stores the received calibration information in the calibration information 181 of the storage unit 180 (step S15).

The provision of information regarding calibration is not limited to the provision in response to the request from the sensor device 10. When the calibration setting module 2036 determines that the predetermined sensor of the sensor device 10 is in a state requiring calibration, the calibration setting module 2036 may transmit information regarding calibration for the sensor to the sensor device 10.

In addition, information regarding new calibration may not be set in response to an inquiry from the sensor device 10. In this case, the calibration setting module 2036 returns to the sensor device 10 that there is no information to be transmitted to the sensor device 10. When the sensor device 10 requests calibration in response to the response that there is no information to be transmitted, the calibration setting module 2036 calculates information regarding calibration.
In the description of FIG. 15, the operation of the sensor device 10 at the time of activation has been described. The operation of acquiring information regarding calibration from the server 20 is not limited to being performed at the time of starting the sensor device 10. The first transmission / reception unit 192 may acquire information on calibration when the sensor is replaced.

(Calibration process in sensor device 10)
The calibration process may be performed by the sensor device 10.

FIG. 16 is a flowchart showing an example of an operation in which the sensor device 10 shown in FIGS. 2 and 3 performs a calibration process.

When performing the calibration process, the user first closes the valves 119 and 1110 to stop the inflow of sample water. The user attaches a drainage tube to the drain valve 1116. The user opens the drain valve 1116 and discharges the sample water to the outside of the sensor device 10. The calibration process of the sensor device 10 may be performed before supplying the sample water to the sensor device 10.

The user takes out the sensors 111 to 115 and 118 from the flow cell 1111, wipes off the water droplets, and reinserts them into the flow cell 1111. The user supplies the first calibration liquid to the flow cells 1111-1 and 1111-2 from which the sample water is discharged. When the user fills the flow cells 1111-1 and 1111-2 with the first calibration liquid, the user opens the air bleeding valve 1115 to bleed the air in the flow cells 1111-1 and 1111-2.

The sensor device 10 causes the touch panel 1119 to display a "calibration start" object for performing the calibration process. The user presses the "calibration start" object displayed on the touch panel 1119. When the "calibration start" object is pressed, the sensor device 10 accepts the selection of the sensor to be calibrated (step S21). For example, the sensor device 10 causes the touch panel 1119 to display a sensor selection screen and accepts a sensor selection from the user.

The user selects a sensor to be calibrated collectively from a plurality of sensors displayed on the selection screen. For example, the user selects the EC sensor 111, the FCL sensor 112, the pH sensor 113, the ORP sensor 114, and the NO3 sensor 115.

When the sensor is selected, the sensor device 10 accepts the selection of the calibration solution (step S22). For example, the sensor device 10 causes the touch panel 1119 to display a calibration liquid selection screen, and accepts the selection of the calibration liquid from the user. The user selects the first calibration solution from the plurality of calibration solutions displayed on the selection screen.

When the calibration liquid is selected, the sensor device 10 receives an instruction to start the calibration process (step S23). For example, the sensor device 10 displays a "start" object on the touch panel 1119 and receives a start instruction from the user. The user presses the "start" object to start the calibration process.

When the calibration process is started, the sensor device 10 receives the first measurement data from the selected sensor by the second transmission / reception unit 193 (step S24). The sensor device 10 stores the received first measurement data in the calibration measurement information 184 of the storage unit 180.

The sensor device 10 estimates whether or not the calibration process of the sensors 111 to 115 is successful by the calibration unit 194 (step S25). Specifically, for example, the calibration unit 194 monitors the transition of the measured value. The calibration unit 194 compares the transition of the measured value stored for each sensor at the time of successful calibration with the transition of the acquired measured value. The calibration unit 194 determines that the calibration is successful, for example, when the transition of the acquired measured value falls within a predetermined range of the expected transition.

If the calibration is successful, the calibration unit 194 determines whether or not the measurement using the assumed calibration solution is completed (step S26). When the measurement using the assumed calibration solution is not completed (No in step S26), the calibration unit 194 shifts the process to step S22.

For example, the user discharges the first calibration liquid from the flow cells 1111-1, 1111-2, and supplies the second calibration liquid to the flow cells 1111-1, 1111-2. The calibration unit 194 performs a sensor calibration process in the flow cells 1111-1 and 1111-2 filled with the second calibration solution. When the calibration process of the sensor using the second calibration solution is successful, the calibration unit 194 shifts the process to step S22.

For example, the user discharges the second calibration liquid from the flow cells 1111-1, 1111-2, and supplies the third calibration liquid to the flow cells 1111-1, 1111-2. The calibration unit 194 performs a sensor calibration process in the flow cells 1111-1 and 1111-2 filled with the third calibration solution. When the calibration process of the sensor using the third calibration solution is successful, the calibration unit 194 shifts the process to, for example, step S27.

When the measurement using the assumed calibration solution is completed (Yes in step S26), the calibration unit 194 creates information on calibration for each sensor based on the information measured for each sensor (step S27). The calibration unit 194 stores the created calibration information in the calibration information 181 of the storage unit 180.

The sensor device 10 transmits the calibration information stored in the calibration information 181 to the server 20 at a predetermined timing by the first transmission / reception unit 192. The sensor device 10 transmits the information stored in the calibration measurement information 184 to the server 20 at a predetermined timing by the first transmission / reception unit 192. The predetermined timing is, for example, as follows.
・ Specified cycle ・ Specified time ・ When the calibration process is completed ・ When the information is stored

(Measurement of sample water: Processing with a sensor)
The sensor device 10 measures the water quality of the sample water using the sensors 111 to 118. Specifically, for example, the sensors 111 to 115 and 118 inserted into the measurement port of the flow cell 1111 and the TUR sensor 117 inserted into the shell 1171 are used to measure the water quality of the sample water.

FIG. 17 is a flowchart showing an example of the operation of the sensor shown in FIG. 7.

The pH sensor 113 shown in FIG. 7 measures, for example, the potential of the sample water filled in the flow cell 1111-1 by the pH electrode 1131 at a preset cycle (step S31). The pH sensor 113 stores the acquired potential as the first measurement data in the memory 11322.

The pH sensor 113 corrects the abnormality included in the first measurement data (step S32). Specifically, the pH sensor 113 reduces the noise contained in the first measurement data by using, for example, the trained model 113221. Specifically, for example, the pH sensor 113 inputs the first measurement data to the trained model 113221 to replace the measured value in which the sudden change occurs with the value estimated from the previous measured value. The measured values without sudden changes are output as they are from the trained model 113221. The pH sensor 113 stores the data output from the trained model 113221 in the memory 11322 as the second measurement data.

The pH sensor 113 transmits the first measurement data and the second measurement data to the sensor device 10 at predetermined timings via the input / output IF 11325. The predetermined timing is, for example, as follows.
・ Predetermined cycle ・ When information is acquired ・ When information is memorized

The TUR sensor 117 inserted into the sensors 111 to 115, 118, and the shell 1171 also operates in the same manner as the pH sensor 113.

(Measurement of sample water: Processing by sensor device 10)
FIG. 18 is a flowchart showing an example of the operation of the sensor device 10 shown in FIG.

The control unit 190 receives the first measurement data and the second measurement data from the sensors 111 to 115, 117, 118 by the second transmission / reception unit 193 (step S41). The control unit 190 stores the received first measurement data and the second measurement data in the measurement information 182 of the storage unit 180.

The control unit 190 calculates the third measurement data from the second measurement data received from the sensors 111 to 115 and 117 and the information related to the calibration corresponding to each sensor by the calculation unit 195 (step S42).

Specifically, the calculation unit 195 calculates the EC value as the third measurement data from, for example, the second measurement data received from the EC sensor 111 and the information regarding the calibration of the EC sensor 111. Further, the calculation unit 195 calculates the FCL value as the third measurement data from, for example, the second measurement data received from the FCL sensor 112 and the information regarding the calibration of the FCL sensor 112. Further, the calculation unit 195 calculates the pH value as the third measurement data from, for example, the second measurement data received from the pH sensor 113 and the information regarding the calibration of the pH sensor 113. Further, the calculation unit 195 calculates the ORP value as the third measurement data from, for example, the second measurement data received from the ORP sensor 114 and the information regarding the calibration of the ORP sensor 114. Further, the calculation unit 195 calculates the nitrate concentration as the third measurement data from, for example, the second measurement data received from the NO3 sensor 115 and the information regarding the calibration of the NO3 sensor 115. Further, the calculation unit 195 calculates the turbidity as the third measurement data from, for example, the second measurement data received from the TUR sensor 117 and the information regarding the calibration of the TUR sensor 117.

The control unit 190 estimates whether or not an abnormality has occurred in the sensors 111 to 118 by the estimation unit 196 (step S43). For example, the estimation unit 196 uses the third measurement data calculated for the sensors 111 to 115 and 117, the first measurement data measured by the FLOW sensor 116, and the second measurement data measured by the TEMP sensor 118, respectively. Input to the trained model 185. If any of the sensors that input the measurement data has an abnormality, it is estimated from the trained model 185 that the abnormality has occurred and that the sensor has an abnormality. Abnormality is output.

Specifically, if any of the sensors that input the measurement data has a failed sensor, from the trained model 185, for example, a sensor that is presumed to have a failure and a sensor that has a failure have occurred. It is output that you are doing. Further, if any of the sensors to which the measurement data is input has a sensor that is deviated from the time of calibration, it is estimated from the trained model 185 that the deviation from the time of calibration is occurring, for example. It is output that there is a deviation between the sensor and the sensor from the time of calibration.

The estimation unit 196 may present the estimation result to the user from the presentation control unit 199.

The control unit 190 determines whether or not the sensor in which the failure has occurred is included by the complement unit 198 (step S44). When the sensor in which the failure has occurred is included (Yes in step S44), the complementary unit 198 has measured the measurement data by the sensor in which the failure has occurred, the measurement data of a plurality of sensors acquired in the past, and the measurement data this time. Complement using the measurement data of other sensors (step S45).

Specifically, for example, when it is estimated that a failure has occurred in the pH sensor 113, the complementary unit 198 discards the third measurement data calculated based on the measurement of the pH sensor 113. The complementary unit 198 includes the third measurement data of the sensors 111 to 115 and 117 acquired in the past, the first measurement data of the FLOW sensor 116, the second measurement data of the TEMP sensor 118, and the sensors 111 and 112 measured this time. , 114, 115, 117, the third measurement data of the FLOW sensor 116, and the second measurement data of the TEMP sensor 118 are used to calculate the complementary measurement data of the pH sensor 113. The complementary unit 198 stores the calculated complementary measurement data in the storage unit 180 as the third measurement data.

When the sensor in which the failure has occurred is not included (No in step S44), the complementary unit 198 shifts the process to step S46.

The control unit 190 determines, by the correction unit 197, whether or not a sensor having a deviation from the calibration time is included (step S46). When a sensor having a deviation from the calibration time is included (Yes in step S46), the correction unit 197 collects measurement data from the sensor having a deviation from the calibration time from a plurality of sensors acquired in the past. Correction is performed using the measurement data and the measurement data of the other sensor measured this time (step S47).

Specifically, for example, when it is estimated that a deviation from the calibration time has occurred in the pH sensor 113, the correction unit 197 corrects the third measurement data calculated based on the measurement of the pH sensor 113. At this time, the correction unit 197 includes the third measurement data of the sensors 111 to 115 and 117 acquired in the past, the first measurement data of the FLOW sensor 116, the second measurement data of the TEMP sensor 118, and the sensor measured this time.

Correct the measurement data. The correction unit 197 stores the corrected third measurement data in the storage unit 180.

When there is no sensor in which the deviation from the calibration has occurred (No in step S46), the control unit 190 ends the process.

In the flowchart shown in FIG. 18, the complementary unit 198 determines in step S44 whether or not the sensor in which the failure has occurred is included. In this determination, the complementary unit 198 may determine whether or not there is only one sensor in which the failure has occurred. When there is only one sensor in which the failure has occurred, the complementary unit 198 uses the measurement data of the sensor in which the failure has occurred, the measurement data of a plurality of sensors acquired in the past, and the measurement of the other sensors measured this time. Complement using data. When two or more sensors have failed, the complementary unit 198 stops the measurement by the sensor device 10.

Further, in the flowchart shown in FIG. 18, the correction unit 197 determines in step S46 whether or not a sensor having a deviation from the calibration time is included. In this determination, the correction unit 197 may determine whether or not there is only one sensor in which the deviation from the time of calibration has occurred. When there is only one sensor that has a deviation from the calibration time, the correction unit 197 uses the measurement data of the sensor that has the deviation from the calibration time, the measurement data of a plurality of sensors acquired in the past, and this time. Correct using the measurement data of other measured sensors. The correction unit 197 stops the measurement by the sensor device 10 when the deviation from the time of calibration occurs in the two or more sensors.

Further, in the above embodiment, the first transmission / reception unit 192 also transmits the measurement data before the correction. As a result, more information will be accumulated.

<4 Modification example>
In the example according to the above embodiment, the case where the sensor device 10 has the touch panel 1119 is described. However, the sensor device 10 does not have to have the touch panel 1119. The control unit 190 may transmit information related to processing by the control unit 190 to the terminal device 30 operated by the user by the first transmission / reception unit 192.

In addition, a plurality of types of the first trained model 2027 may be created according to the analysis criteria. The first trained model 2027 may be of different types depending on the contract.

In the example according to the above embodiment, the case where the sensor device 10 has a sensor capable of measuring different items has been described. However, any of the sensors included in the sensor device 10 may be capable of measuring the same item. For example, when the value of one sensor changes and is not the same as the value of the other sensor, the sensor device 10 determines that an abnormality has occurred in one sensor. This makes it possible to more accurately determine whether or not an abnormality has occurred in the sensor.

In the above embodiment, when the sensor device 10 estimates that the sensor that has detected the measured information includes a sensor deviated from the time of calibration by the estimation unit 196, the sensor device 10 informs the server 20 about the calibration of the sensor. May be requested. At this time, the deviation from the calibration time may be different depending on whether the measured value is corrected or the information regarding the calibration is requested. For example, the deviation is set to be larger when requesting information on calibration than when correcting the measured value. In this way, the estimation unit 196 estimates the sensor that needs to be calibrated among the plurality of sensors based on the measurement data of the plurality of items acquired from the plurality of sensors and the measurement data of the plurality of items acquired in the past. .. Then, the first transmission / reception unit 192 requests the server 20 for information regarding the calibration of the sensor that requires the estimated calibration.
