[Embodiment 1]
Hereinafter, the embodiment of the present invention will be described below with reference to FIGS. 1 to 13.

<Data management system>
First, the data management system 100 according to the present embodiment will be described with reference to FIG. FIG. 2 is a diagram showing an example of the data management system 100 according to the present embodiment.

The data management system 100 (1) measures the concentration of a predetermined substance in a predetermined environment (that is, contained in a predetermined space) using a measuring instrument, and (2) various measurement-related data including the measurement result. A simple environment measuring system for managing data on a network and (3) displaying various data managed on the network on a user terminal. In order to realize the processing, the data management system 100 includes an inspection kit 1, a measuring device 2, a portable information terminal 3, a server 4 (storage device), and a PC (Personal Computer) 5. The portable information terminal 3 and the PC 5 correspond to the user terminal.

In the present embodiment, the predetermined environment (predetermined space) is, for example, water (including wastewater) used in factories, sewage treatment plants, laboratories, households, agriculture, etc., a water environment including a river or the sea. As described below. That is, in the present embodiment, the water quality is measured by measuring the concentrations of various substances contained in water. Not limited to this, the data management system 100 can be used as a device for measuring the state of various environments such as the atmosphere or soil.

In the data management system 100, the measuring device 2 can be communicatively connected to the portable information terminal 3 using short-range wireless communication. In this embodiment, Bluetooth (registered trademark) Low Energy (BLE) is used as the short-range wireless communication, but other Bluetooth standard, ZigBee (registered trademark), or the like may be used. When Bluetooth Low Energy is used as the short-distance wireless communication, the power consumption in the data communication between the measuring device 2 and the portable information terminal 3 can be suppressed to be low. The measuring device 2 is not limited to the above-mentioned short-distance wireless communication and may be any device capable of communicating with the portable information terminal 3 by wireless communication.

Further, in the data management system 100, the server 4 can be communicatively connected to the portable information terminal 3 and the PC 5 via a network line. As the network line, various lines such as an Internet line, a wireless LAN (Local Area Network) such as Wi-Fi (registered trademark), a WAN (Wide Area network), and a mobile phone line can be used. Further, the server 4 may be connected to the portable information terminal 3 and the PC 5 by communication, and may be connected by wire.

The measuring device 2 measures the absorbance (transmittance) of the water (that is, the measurement target substance contained in the water) by irradiating the measurement target water containing the reagent 11 of the test kit 1 with light. The measuring device 2 calculates the concentration of the substance to be measured contained in the water to be measured by comparing the measured absorbance with the calibration curve data for the substance to be measured. That is, the calibration curve data is used to measure the concentration of the substance. The calculated concentration of the substance (measurement result) is transmitted to the measuring device 2 using short-distance wireless communication, and is also transmitted from the portable information terminal 3 to the server 4 via the network line. Further, various data including measurement results managed by the server 4 are transmitted to the PC 5 as needed. Thereby, the measurement result can be managed not only in the measuring device 2 but also in the portable information terminal 3 and the server 4. In addition, the user can browse the measurement result on the portable information terminal 3 or the PC 5. That is, the user can easily confirm the measurement result (that is, the state of the environment) by a terminal other than the measuring device 2. In addition, users who have the authority to use the data management system 100 (that is, various users including not only the measurement person) can easily confirm the measurement result via the portable information terminal 3 or the PC 5. ..

The calibration curve data is managed by the server 4 and is transmitted to the portable information terminal 3 via the network line. This allows the portable information terminal 3 to manage the calibration curve data. Further, among the calibration curve data managed by the portable information terminal 3, at least a part selected by the user is transmitted to the measuring instrument 2 using short-range wireless communication. As a result, it is possible to prevent the calibration curve data (that is, unnecessary calibration curve data) corresponding to the measurement item that is not the measurement target by the user from being stored (saved) in the measuring instrument 2. Therefore, for example, even when the calibration curve data is updated or added, the storage capacity of the measuring instrument 2 can be efficiently used, and all the measuring instrument 2 including unnecessary calibration curve data can be used. It is possible to save the user the trouble of selecting from all the measurement items corresponding to the calibration curve data.

The inspection kit 1, the measuring instrument 2, the portable information terminal 3, the server 4, and the PC 5 among the configurations included in the data management system 100 according to the present embodiment will be described below.

<Test kit>
Next, the inspection kit 1 according to the present embodiment will be described with reference to FIG. 3A is a diagram showing the appearance of the inspection kit 1, and FIG. 3B is a diagram showing details of the inspection kit 1.

The inspection kit 1 is prepared for each substance that is a measurement item, and includes a reagent 11 for detecting the substance, and a measured value analogy colorimetric paper 12 for visually confirming the measurement result. In the present embodiment, the test kit 1 is configured by packing the reagent 11 and the measured value analogy colorimetric paper 12 as shown in FIG. 3B in a box as shown in FIG. Provided to users. Examples of the substance that is a measurement item include COD, PO ₄ , NH ₄ , NO _{3 and the} like that may be contained in industrial wastewater. Not limited to this, the substances include all substances that can be contained in the environment to be measured (that is, substances that can be measured), and in order to obtain the measurement results for these substances, It suffices that the reagent 11 and the measurement value analogy colorimetric paper 12 corresponding to each are prepared as the inspection kit 1.

When the water to be measured contains COD, for example, the reagent 11 for detecting COD develops color by containing the water. The degree of color development of the reagent 11 varies depending on the proportion of COD contained in water. On the measured value analogy colorimetric paper 12, density values (unit: mg/L) associated with the previously measured degree of color development are discretely shown. Therefore, the user can confirm the approximate value of the density value by comparing the color-developed reagent 11 with the measured value analogy colorimetric paper 12. However, in the present embodiment, the concentration of the substance is measured by the measuring device 2, so the inspection kit 1 does not necessarily need to include the measured value analogy colorimetric paper 12.

<Measuring device>
Next, the measuring device 2 according to this embodiment will be described with reference to FIGS. 1 and 4. FIG. 1 is a block diagram showing details of the measuring device 2, the portable information terminal 3, and the server 4 included in the data management system 100 according to the present embodiment. 4A is a diagram showing the appearance of the measuring instrument 2, FIG. 4B is a top view of the measuring instrument 2, and FIG. 4C is a diagram showing the measuring cup 6.

The measurement display 24 displays a measurement mode, a measurement item, a measurement area, a measurement result, and the like, and is composed of, for example, an LCD (Liquid Crystal Display).

The measuring unit 27 measures the concentration of the substance to be measured. The measuring unit 27 includes a recess capable of accommodating the measuring cup 6, a light source 22 (see FIG. 1), and a light receiving unit 23 (see FIG. 1).

The light source 22 emits light toward the recess, and is composed of, for example, a light emitting diode (LED). At the time of zero adjustment or measurement of the concentration of the substance, the measurement cup 6 containing the water to be measured is inserted into the recess, and the light emitted from the light source 22 is applied to the water to be measured.

In the present embodiment, the light source 22 is a red LED that emits red light (for example, a peak wavelength range is 610 nm or more and less than 750 nm) and green light (for example, a peak wavelength range is 495 nm) so that a plurality of measurement items can be measured. The chip is provided with three light sources, a green LED that emits light of less than 570 nm) and a blue LED that emits blue light (for example, a peak wavelength range of 450 nm or more and less than 495 nm). In order to improve the measurement accuracy, it is preferable that the peak wavelength of red light is near 615 nm, the peak wavelength of green light is around 525 nm, and the peak wavelength of red light is around 470 nm. The types of light sources are not limited to the above as long as the measurement of a plurality of measurement items can be realized. That is, it can be said that the measuring device 2 is a multi-item absorptiometer capable of measuring a plurality of measurement items.

The light receiving section 23 receives the light emitted from the light source 22 and passing through the concave portion, and measures the intensity of the received light (reception intensity). At the time of zero adjustment or measurement of the concentration of the substance, the light emitted from the light source 22 and transmitted through the water to be measured is received.

The cover 28 is a lid that protects the measuring unit 27. The cover 28 is opened at the time of zero adjustment or measurement of the concentration of the substance to open the measurement unit 27 and allow the measurement cup 6 shown in FIG. 4C to be inserted. The measuring cup 6 contains water to be measured and is inserted into the measuring section 27 at the time of zero adjustment or measuring the concentration of the substance. The measuring cup 6 has a shape that can be inserted into the concave portion of the measuring unit 27, and has a surface on which a marked line ML indicating the amount of water to be measured is formed.

Further, as shown in FIG. 1, the measuring device 2 includes a measuring device control unit 25 and a measuring device storage unit 26.

Under the control of the data processing unit 252, the data transmission/reception unit 251 transmits, for example, data indicating the measurement result, the measurement date/time, and the version of the measuring device 2 to the portable information terminal 3, or the measurement item selected by the user, the measurement The item-related data including the area, the measurement point, and the reaction time, and the calibration curve data corresponding to the measurement item are received from the portable information terminal 3. The reaction time is set to a time sufficient for completing the reaction between the substance of each measurement item and the reagent 11 that reacts with the substance.

The data processing unit 252 processes various data based on, for example, a user instruction received by the measurement operation unit 21, and includes, for example, a measurement processing unit 253.

The substance to be measured may be selected according to a user's instruction or may be the substance that was previously measured. Further, in the present embodiment, the measurement processing unit 253 calculates the measurement result up to the second decimal place (resolution: 0.01 mg/L), but the present invention is not limited to this.

As described above, in the present embodiment, since the measurement result is calculated using the measuring device 2, the measurement result can be obtained without depending on the user's sense and judgment. That is, it is possible to easily and accurately obtain the measurement result as compared with the case where the user visually obtains the measurement result by using the measurement value analogy colorimetric paper 12.

Further, the data processing unit 252 controls the data transmitting/receiving unit 251 when the data communication with the portable information terminal 3 is possible (when the data communication with the portable information terminal 3 is established). The measurement processing unit 253 transmits the measurement result stored in the measuring device storage unit 26 to the portable information terminal 3.

For example, the measurement display control unit 254 displays a screen based on a user instruction, a measurement result calculated by the measurement processing unit 253, and the like on the measurement display 24 under the control of the data processing unit 252.

The measuring device storage unit 26 stores various control programs executed by the measuring device control unit 25, and is configured by a non-volatile storage device such as a hard disk or a flash memory. The measuring device storage unit 26 stores the measurement result measured by the measurement processing unit 253 for each measurement item. The measurement result is stored in association with the measurement date and time, the measurement area, and the measurement point. In the measuring device storage unit 26, the measurement item selected by the user using the portable information terminal 3, the calibration curve data corresponding to the measurement item, and the substance of the measurement item and the reagent 11 react. The reaction time is associated and stored.

In the present embodiment, the measurement result is transmitted from the measuring device 2 to the portable information terminal 3 and managed by the portable information terminal 3 or the server 4. Therefore, it is not necessary for the measuring instrument 2 to store and manage a large amount of measurement results. The measurement result of the measurement device storage unit 26 is such that the user can immediately confirm it by using the measurement device 2 and that it can be held until the data communication with the portable information terminal 3 is established. Should be stored. In the present embodiment, the measuring device storage unit 26 can store several tens of measurement results (for example, about 50). When the maximum value of the measurement result is exceeded, the oldest measurement result is overwritten with the latest measurement result.

<About the light source 22>
Generally, in a light emitting diode, the emission wavelength shifts slightly from a predetermined emission wavelength depending on the magnitude of the current. When a light emitting diode is used as the light source 22, the following process may be performed in the manufacturing process of the measuring device 2 in order to correct this shift.

Specifically, an optical filter that transmits a predetermined emission wavelength is arranged in front of the light source 22, and the magnitude of the current applied to the light source 22 is controlled so that the light from the light source 22 passes through the optical filter. .. That is, the magnitude of the current when passing through the optical filter is set as the current value applied to the light source 22.

Further, the measuring device 2 includes an electronic volume in addition to the constant current circuit for the light source 22. When the magnitude of the current is adjusted, the signal level obtained by the light receiving circuit forming the light receiving unit 23 also changes with the adjustment. By adjusting the amplifier gain in the light receiving circuit with the electronic volume, the change in the signal level is suppressed and the signal level is adjusted to a desired value.

As a result, it is possible to suppress the wavelength shift of the light emitted from the light source 22 for each manufactured measuring device 2. Therefore, it is possible to suppress the occurrence of an error in the absorbance caused by the wavelength shift, and it is possible to improve the yield. Moreover, since the occurrence of error can be suppressed, the measurement accuracy can be improved. Further, there is an effect that it is not necessary to prepare a plurality of calibration curve data for one measurement item (reagent 11) in consideration of the wavelength shift.
