If so (YES in step S28 of FIG. 8), the setting related to the measurement function is made to the conversion unit 1009 and the data correction unit 1010 based on this information (step S29 of FIG. 8).

The measurement function includes a function of converting the value indicated by the digital data measured by the sensor 3 and AD-converted by the AD module 1 into a quantity to be measured by a conversion formula, a function of correcting the digital data, and the like.

The data correction unit 143 of the AD module 1 corrects digital data when data correction is required (YES in step S102 of FIG. 10) (step S103 of FIG. 10). The case where data correction is necessary is, for example, a case where a correction parameter read from the sensor 3 by the data reading unit 142 exists.

The correction process is a process of multiplying the value indicated by the digital data to be corrected by the ratio (ratio) obtained by the ratio / bias data to add the bias, or the value indicated by the digital data to be corrected is based on the correction parameter. There is a process of straight line correction. As is clear from the above description, this correction process is not essential in the present invention.
Further, when performing such a correction process on the cloud server 101 or the user terminal 102 side, it is not necessary to perform the correction process in step S103 in the AD module 1.

Further, the AD module 1 can supply the power received from the NW module 2 via the communication / power supply / reception male connector 11 to the sensor 3 via the communication / power supply / reception female connector 10. However, in the present invention, the power supply to the sensor 3 is not indispensable, and the sensor 3 may be operated by the power source of the sensor itself.

FIG. 11 is a flowchart illustrating the communication process of the AD module 1 with the NW module 2. When the data transmission unit 141 of the AD module 1 receives a data transfer request from the NW module 2 via the communication / power supply / reception male connector 11 and the USB controller 12 (YES in step S200 of FIG. 11), the data transmission unit 141 encrypts from the memory 15. The digital data is read (step S201 in FIG. 11), and the read encrypted digital data is transmitted to the NW module 2 via the USB controller 12 and the communication / power supply / reception male connector 11 (step S202 in FIG. 11).

As described above, when the encrypted digital data is overwritten and saved, one sample of the encrypted digital data is transmitted to the NW module 2, and when the encrypted digital data is additionally saved, it is saved in the memory 15. All encrypted digital data is transmitted. After transmission, the data additionally stored in the memory 15 may be deleted.

When the decryption unit 149 of the AD module 1 receives encrypted digital data from the NW module 2 via the communication / power supply / reception male connector 11 and the USB controller 12 by the process of step S305 described later (in FIG. 11 step S203). YES), the encrypted digital data is decrypted using the encryption key Kb (step S204 in FIG. 11), and the decrypted digital data is written in the memory 15 (step S205 in FIG. 11).

Then, the data transmission unit 141 of the AD module 1 transmits the digital data decoded by the decoding unit 149 in steps S204 and S205 to the NW module 2 via the USB controller 12 and the communication / power supply / reception male connector 11 (FIG. 11). Step S206).

Further, when the parameter setting unit 144 of the AD module 1 includes the AD conversion parameter setting data addressed to the AD module in the data decoded by the decoding unit 149 in steps S204 and S205 (in FIG. 11 step S207). YES), AD conversion parameter setting is performed (FIG. 11, step S208). The AD conversion parameter at this time includes, for example, the sampling period of the AD conversion unit 13. In this way, the setting of the AD conversion unit 13 can be changed.

The AD module 1 performs the processes of steps S200 to S208 until, for example, the AD module 1 is removed from the NW module 2 or the NW module 2 is removed from the power supply 4 and the power supply is cut off (YES in step S209 of FIG. 11). Repeat.

FIG. 12 is a flowchart illustrating communication processing of the NW module 2 with the AD module 1. When the data transfer request transmission timing comes (YES in step S300 of FIG. 12), the data reading unit 240 of the NW module 2 transmits the data transfer request to the AD module 1 via the USB controller 23 and the communication / power supply / reception female connector 20. (FIG. 12 step S301). As described above, the AD module 1 transmits encrypted digital data in response to a data transfer request.

When the data reading unit 240 receives the encrypted digital data from the AD module 1 via the communication / power supply / reception female connector 20 and the USB controller 23 (YES in step S302 of FIG. 12), the data reading unit 240 writes the encrypted digital data to the memory 25. (FIG. 12 step S303).

Next, when the data transmission unit 244 of the NW module 2 receives the encrypted digital data from the cloud server 101 as described later (step S304 in FIG. 12), the data transmission unit 244 passes through the USB controller 23 and the communication / power supply / reception female connector 20. The encrypted digital data is transmitted to the AD module 1 (step S305 in FIG. 12). As described in steps S203 to S205 of FIG. 11, the encrypted digital data is decrypted in the AD module 1.

The parameter setting unit 243 of the NW module 2 includes communication parameter setting data addressed to the NW module in the digital data decoded by the AD module 1 and transmitted from the AD module 1 by the processing of steps S203 to S206 of FIG. (YES in step S306 of FIG. 12), communication parameters are set for the communication unit 241 and the communication circuits 26 and 29 (step S307 of FIG. 12). In this way, the settings related to communication with the cloud server 101 can be changed.

The NW module 2 may be used, for example, until the communication / power supply / reception male connector 11 of the AD module 1 is disconnected from the communication / power supply / reception female connector 20 and the connection with the AD module 1 is disconnected, or the NW module 2 is disconnected from the power supply 4. The process of steps S300 to S307 is repeated until the power supply is exhausted (YES in step S308 of FIG. 12).

FIG. 13 is a flowchart illustrating a communication process of the NW module 2 with the cloud server 101. When the communication unit 241 of the NW module 2 reaches the transmission timing of the encrypted digital data (YES in step S400 in FIG. 13), the encrypted digital data transmitted from the AD module 1 and stored in the memory 25 (step S303). Is taken out from the memory 25 and passed to the communication circuit 26. The transmission timing of the encrypted digital data is, for example, the timing at which the encrypted digital data is stored in the memory 25 and transmission becomes possible. Needless to say, when the data is taken out from the memory 25, the amount of encrypted digital data taken out is lost from the memory 25.

The communication circuit 26 converts the encrypted digital data passed from the communication unit 241 into a wireless signal and wirelessly transmits the encrypted digital data from the antenna 22 to the cloud server 101 on the network (step S401 in FIG. 13). Examples of the wireless communication standard of the communication circuit 26 include LPWA (Low Power Wide Area) and 4G, but the present invention is not limited to these wireless communication standards. As described above, the settings related to communication with the cloud server 101 can be changed by the communication parameter setting data, but the initial settings for the communication unit 241 and the communication circuits 26 and 29 are performed at the time of manufacturing the NW module 2. Therefore, it is possible to start communication with the cloud server 101 without setting by the communication parameter setting data.

When the communication unit 241 of the NW module 2 receives the encrypted digital data from the cloud server 101 on the network via the antenna 22 and the communication circuit 26 (YES in step S402 of FIG. 13), the communication unit 241 stores the encrypted digital data in the memory. Write to 25 (step S403 in FIG. 13). As a result, as described in steps S304 and S305 of FIG. 12, the encrypted digital data is transmitted to the AD module 1 and further used for setting communication parameters in steps S306 and S307 of FIG.

The NW module 2 may be used, for example, until the communication / power supply / reception male connector 11 of the AD module 1 is disconnected from the communication / power supply / reception female connector 20 and the connection with the AD module 1 is disconnected, or the NW module 2 is disconnected from the power supply 4. The process of steps S400 to S403 is repeated until the power supply is exhausted (YES in step S404 of FIG. 13).

In this embodiment, the encrypted digital data received from the AD module 1 is once written in the memory 25 and then transmitted, but the present invention is not limited to this, and the encrypted digital data is stored in the memory 25. You may send it without sending it.
In this embodiment, when the NW module 2 transmits a data transfer request to the AD module 1, encrypted digital data is transmitted from the AD module 1, but the data transmission unit 141 of the AD module 1 is not limited to this. When the value of the encrypted digital data that has been AD-converted by the AD conversion unit 13 and encrypted by the encryption unit 140 exceeds a predetermined threshold value, or the number of encrypted digital data stored in the memory 15 is increased. When the predetermined threshold value is exceeded, the encrypted digital data may be transmitted to the NW module 2.

Conventionally, sensors for IoT and new sensors for the next generation have been developed, but there are few cases that lead to social implementation. One of the factors was the technical and cost issues of constructing a measurement system for collecting and controlling data via a network. According to this embodiment, when a new sensor is developed, a measurement system can be realized easily and at low cost, which can be linked to social implementation. In the case of sensors to be developed in the future, by matching the specifications of the input to the AD module 1 with the standard of the AD module 1, a demonstration experiment can be performed immediately.

Further, in the USB converter disclosed in Patent Document 1, it is necessary to connect to a computer, but in this embodiment, if the NW module 2 is connected to the power supply 4 provided with the communication / power supply / reception female connector 40. Well, you don't have to connect to a computer.

Therefore, the short-range wireless communication unit 1037 decodes the encrypted digital data received via the communication circuit 1036 and the antenna 1035 using the short-range wireless communication encryption key to obtain information.

On the other hand, when the short-range wireless communication unit 330 of the sensor 3 receives a data transfer request from the user terminal 102 via the antenna 37 and the communication circuit 38 (YES in step S60 of FIG. 19), the encrypted digital data from the memory 34. (Information such as sensor ID, measured amount type, output signal type, conversion formula, output signal range, correction parameter, rated power consumption, etc.) is read out (FIG. 19, step S61). As described above, the encrypted digital data read from the memory 34 is pre-encrypted using a predetermined short-range wireless communication encryption key.
