15 is a flowchart illustrating an operation of determining the number of failures of a sensor module according to an embodiment.

First, the control device may classify a first chlorine measuring device corresponding to a predetermined determination condition in which deterioration state information is among the chlorine measuring devices installed for each area of the tank 10.

The deterioration state information according to an embodiment includes whether or not harmonics are affected by the leakage current of each of the chlorine measuring devices, the number of sensor modules in a faulty state among sensor modules included in each of the chlorine measuring devices, and the number of sensor modules that are inferior in performance Can include.

Specifically, the control device may analyze a change in current according to the supplied power supplied from the power supply device to each of the plurality of chlorine measuring devices. The control device may derive the deterioration state of each of the chlorine measuring devices by applying the analyzed change trend to a predefined determination condition.

The predetermined determination condition according to an embodiment is that the change of current according to the power supplied to each of the chlorine measuring devices when the chlorine measuring devices are driven is any one of a plurality of sensor modules included in each of the chlorine measuring devices in the past. If a failure or deterioration of performance actually occurs in the above, if it is similar within a predefined error range with any one of the current change trends according to the power supplied to the chlorine measuring device, it is said that the chlorine measuring device is abnormal according to the deterioration condition. It may be a condition to determine.

Hereinafter, a case in which the first chlorine measuring device is classified as an abnormal chlorine measuring device according to the deterioration state is described, but is not limited thereto, and the second chlorine measuring device and the third chlorine measuring device are also abnormal according to the deterioration state. It can also be classified as a chlorine measuring device.

In step S1501, the control device may acquire the rated current of the first chlorine measuring device.

The rated current means the current consumed by the first chlorine measuring device during normal operation. The control device may have a database of standard information of the chlorine measuring devices in advance. The control device can obtain the rated current of the first chlorine measuring device from the database.

According to an embodiment, when the first chlorine measuring device is implemented as one measuring device, the control device may acquire a rated current for one measuring device, and the first chlorine measuring device is implemented as a plurality of measuring devices. If so, the control device can obtain the rated current for a plurality of measuring devices.

In step S1502, the control device may measure a supply current supplied from the power supply device to the first chlorine measuring device.

In step S1503, the control device may acquire current consumption of one sensor module included in the first chlorine measuring device.

The consumption current means the current consumed by one sensor module included in the first chlorine measuring device during normal operation. The control device may have a database of current consumption information of one sensor module in advance. The control device may obtain current consumption of one sensor module included in the first chlorine measuring device from the database.

In step S1504, the control device divides the difference between the rated current of the first chlorine measuring device and the supply current supplied to the first chlorine measuring device by the current consumption of one sensor module, and the first chlorine measuring device is faulty. The number of failures, which is the number of sensor modules, can be determined.

For example, when the first chlorine measuring device is implemented as a “100W 4-sensor module”, the rated current of the first chlorine measuring device may be 50mA, and the current consumption of one sensor module may be 12.5mA. When the supply current supplied to the first chlorine measuring device is 50 mA, the control device may determine that all sensor modules of the first chlorine measuring device are in normal operation. If the current supplied to the first chlorine measuring device is 37.5mA, the control device can determine one sensor module as the number of failures. When the current supplied to the first chlorine measuring device is 25 mA, the control device can determine the number of failures of two sensor modules. If the current supplied to the first chlorine measuring device is 12.5mA, the control device can determine the number of failures of three sensor modules. If the current supplied to the first chlorine measuring device is 0 mA, the control device can determine the number of failures of four sensor modules.

In addition, when the first chlorine measuring device is implemented as a "200W 6 sensor module", the rated current of the first chlorine measuring device may be 90mA, and the current consumption per sensor module may be 15mA. When the supply current supplied to the first chlorine measuring device is 90 mA, the control device may determine that all modules of the first chlorine measuring device are in normal operation. If the current supplied to the first chlorine measuring device is 75 mA, the control device may determine one sensor module as the number of failures. If the current supplied to the first chlorine measuring device is 60 mA, the control device can determine the number of failures of two sensor modules. If the current supplied to the first chlorine measuring device is 45A, the control device can determine the number of failures of three sensor modules. If the current supplied to the first chlorine measuring device is 30 mA, the control device can determine the number of failures for four sensor modules. If the current supplied to the first chlorine measuring device is 15 mA, the control device can determine the number of failures of five sensor modules. If the current supplied to the first chlorine measuring device is 0 mA, the control device may determine the number of failures of six sensor modules.

16 is a flowchart illustrating an operation of determining the number of failures and deterioration in performance of the sensor module according to an embodiment.

Referring to FIG. 16, first, in step S1601, the control device may acquire the total number of sensor modules included in the first chlorine measuring device.

The control device may have a database of standard information of the chlorine measuring devices in advance. The control device may obtain the total number of sensor modules included in the first chlorine measuring device from the database.

In step S1602, the control device may cause a failure in the first chlorine measuring device by dividing the difference between the rated current of the first chlorine measuring device and the supply current supplied to the first chlorine measuring device by the current consumption of one sensor module. The number of failure candidates, which is the number of predicted sensor modules, can be defined.

The operation of deriving a value obtained by dividing the difference between the rated current of the first chlorine measuring device and the supply current supplied to the first chlorine measuring device by the current consumption of one sensor module may be the same as the operation described with reference to FIG. 15.

The control device does not determine the number of faults, which is the number of faulty sensor modules in the first chlorine measuring device, in order to distinguish between a faulty sensor module and a sensor module that is not faulty but causes performance degradation. , Can be determined by the number of failure candidates of the sensor module.

The control device may determine the number of failures and the number of performance degradations of the sensor modules included in the first chlorine measuring device through detailed operations below, based on the number of failure candidates of the sensor module.

In step S1603, the control device may calculate an expected noise of the supply current supplied to the first chlorine measuring device based on a ratio of the number of failure candidates of the sensor modules of the first chlorine measuring device and the total number of sensor modules.

When a part of the sensor module in the first chlorine measurement device fails, a disconnection or a high resistance region that deviates from the original circuit design of the first chlorine measurement device occurs. Such disconnection or high resistance causes impedance disturbance of a detailed region of the first chlorine measuring device, and accordingly, noise of the current supplied to the first chlorine measuring device is generated. The larger the number of sensor modules in which the failure has occurred in the first chlorine measuring device, the more impedance disturbance regions that generate current noise. In short, as the number of failure candidates increases in the number of sensor modules included in the first chlorine measuring device, not only the magnitude of the supply current supplied to the first chlorine measuring device decreases, but also the supply current supplied to the first chlorine measuring device Noise increases.

The control device may determine what percentage the number of failure candidates of the sensor module occupies with respect to the total number of sensor modules of the first chlorine measuring device. Based on this ratio, the control device can calculate an expected noise of the supply current supplied to the first chlorine measuring device. The predicted noise may be calculated by referring to current noise data according to the number of failures of the defective sensor modules compared to the total number of sensor modules for each chlorine measuring device that has been previously databased.

In step S1604, the control device may determine whether a noise difference between the noise measured in the supply current supplied to the first chlorine measuring device and the expected noise is within a predefined error range.

When it is determined in step S1604 that the noise difference falls within a predefined error range, in step S1605, the control device may determine the number of failure candidates as the number of failures, which is the number of sensor modules that have a failure in the first chlorine measuring device.

Specifically, the control device may measure noise in the supply current supplied to the first chlorine measurement device, and determine whether an error between the measurement noise and the expected noise is within a predefined error range. The predefined error range may be differently employed according to embodiments. When the error between the measurement noise and the expected noise is within the predefined error range, the control device is similar to the current noise according to the number of failures of the defective sensor module compared to the total number of sensor modules for each chlorine measurement unit that has been previously databased. In the first chlorine measuring device, the number of failures, which is the number of defective sensor modules, may be determined as it is using the number of candidate failures.

If it is determined in step S1604 that the noise difference is outside the predefined error range, in step S1606, the control device calculates an integer value by rounding the noise difference from the value divided by the predefined unit error, and calculates an integer value from the number of failure candidates. Through the value subtracted from, it can be determined as the number of failures, which is the number of sensor modules having failures in the first chlorine measuring device.

Specifically, when the noise difference between the measurement noise of the supply current supplied to the first chlorine measurement device and the expected noise exceeds a predefined error range, the control device divides the noise difference by a predefined unit error and divides the value An integer value is calculated by rounding to, and a value subtracting the integer value from the number of failure candidates may be determined as the number of failures of the sensor module included in the first chlorine measuring device.

When the first chlorine measuring device includes a sensor module that has not yet failed but shows a performance degradation, the sensor module shows a malfunction rather than non-operation, and consumes current and voltage irregularly or differently from the original sensor module. Accordingly, when the first chlorine measurement device includes a sensor module showing a performance degradation, impedance disturbance occurs more severely than when the first chlorine measurement device includes a sensor module in which a failure occurs. Therefore, if the noise difference between the measurement noise of the supply current supplied to the first chlorine measurement device and the expected noise exceeds a predefined error range, it is reasonable to estimate that the performance of the sensor module is deteriorated, not the failure of the sensor module.

On the other hand, when the sensor module causes performance degradation, since the sensor module does not correspond to a case of disconnection, unlike a case of a failure, a predetermined current flows through the sensor module. Therefore, if the supply current supplied to the first chlorine measuring device when n failures of the sensor module and the supply current supplied to the first chlorine measuring device when the sensor module shows m performance degradation are the same, at least m> n The relationship is established.

When the noise error of the measurement noise and the expected noise of the supply current supplied to the first chlorine measuring device is out of a predefined error range, the noise error is divided by a predefined unit error and the divided value is rounded to an integer value. Can be obtained. The predefined unit error may be noise of a current supplied to the first chlorine measuring device when one sensor module fails compared to the total number of sensor modules.

The control device may determine the number of failures, which is the number of defective sensor modules in the first chlorine measuring device, by excluding the integer value from the number of failure candidates.

In step S1607, the control device may determine the number of deteriorated performance, which is the number of sensor modules whose performance is degraded in the first chlorine measuring device, through a value multiplied by 2 by the integer value.

For example, when the first chlorine measuring device is implemented as a “100W 4-sensor module”, the rated current of the first chlorine measuring device may be 50 mA, and the current consumption of one sensor module may be 12.5 mA.

When the supply current supplied to the first chlorine measuring device is 50 mA, the control device may determine the entire module as normal operation.

The control device may define the number of failure candidates as one if the supply current supplied to the first chlorine measuring device is 37.5 mA. The control device may calculate the predicted noise of the supply current supplied to the first chlorine measuring device based on a ratio of 1 which is the number of failure candidates and 4 which is the number of sensor modules.

The control device may determine whether a noise difference between the measured noise and the expected noise exceeds a predefined error range. When the noise difference between the measured noise and the predicted noise is outside a predefined error range, the control device may obtain an integer value by dividing the noise difference by a predefined unit error and rounding the divided value. The integer value may be 1, for example. The predefined unit error may be noise of a supply current supplied to the first chlorine measuring device when one sensor module fails in the first chlorine measuring device composed of a total of four sensor modules.

When the noise difference between the measurement noise and the expected noise is within a predefined error range, the control device may determine the number of failures of the sensor module having a failure in the first chlorine measurement apparatus as one.

When the noise difference between the measured noise and the predicted noise is outside the predefined error range, if the integer value obtained above is 1, the first chlorine is measured by subtracting the integer value from the number of failure candidates. It can be determined by the number of failures of the sensor module that has a failure in the device.

In addition, the control device may determine "2", which is twice the integer value obtained above, as the number of performance degradation of the sensor module whose performance is degraded in the first chlorine measuring device.

Through the above, when a current equal to or less than the rated current is supplied to the first chlorine measuring device, the control device can discriminate and determine whether the sensor module included in the first chlorine measuring device is defective or deteriorated in performance.
