  As described above, the AD module 1 and the NW module 2 are provided with male and female connectors of the same standard, respectively, and the communication / reception / feeding male connector 11 of the AD module 1 is replaced with the communication / reception / feeding female connector of the NW module 2. By inserting it into 20, it is possible to connect the AD module 1 and the NW module 2 as shown in FIG.

  Further, as shown in FIG. 1C, the sensor 3 and the AD module 1 are connected by inserting the communication / power receiving / feeding male connector 30 of the sensor 3 into the communication / power receiving / feeding female connector 10 of the AD module 1. It is possible to connect the NW module 2 and the power supply 4 by inserting the communication / power supply / reception male connector 21 of the NW module 2 into the communication / power supply / reception female connector 40 of the power supply 4.

The NW module 2 operates by receiving power supply from the power supply 4 and supplies the power received from the power supply 4 to the AD module 1 via the communication / power supply / reception female connector 20. As the power supply 4, if the power supply 4 includes the communication / power supply / reception female connector 40 and has a power capacity necessary for the operation of the AD module 1 and the NW module 2 (or the AD module 1, the NW module 2, and the sensor 3), It can be used without restriction.
Examples of the communication / power supply / reception female connectors 10, 20, 40 and the communication / power supply / reception male connectors 11, 21, 30 include, for example, a USB connector.

  Next, the configurations and operations of the AD module 1 and the NW module 2 will be described in more detail. FIG. 2 is a block diagram showing the configuration of the AD module 1. The AD module 1 includes a communication / reception / feeding female connector 10, a communication / reception / feeding male connector 11, and a USB controller 12 that controls transmission / reception of signals through the communication / reception / feeding female connector 10 or the communication / reception / feeding male connector 11. , AD converter 13, a CPU (Central Processing Unit) 14, and a memory 15.

  The power supply line of the AD module 1 is connected to the positive power supply terminal (VBUS) of the communication / power supply / reception female connector 10 and the positive power supply terminal (VBUS) of the communication / power supply / reception male connector 11 There is a wire 16 and a negative power supply line connecting the GND terminal of the communication / power supply / reception female connector 10 and the GND terminal of the communication / power supply / reception male connector 11, but in FIG. Omitted.

The CPU 14 executes the processing described in the present embodiment in accordance with the program stored in the memory 15, and the encryption unit 140, the data transmission unit 141, the data reading unit 142, the data correction unit 143, the parameter setting unit 144, and the time stamp addition. It functions as the unit 145, the temperature data addition unit 146, and the position data addition unit 147.
The USB controller 12, the AD conversion unit 13, the CPU 14, and the memory 15 operate by receiving power supply from the communication / power supply / reception male connector 11 or the communication / power supply / reception female connector 10.

  FIG. 3 is a flowchart illustrating an input process from the sensor 3 of the AD module 1. First, the data reading unit 142 of the AD module 1 reads sensor ID (identification information) data and sensor adjustment data from the sensor 3 connected to the communication / power supply / reception female connector 10 (step S100 in FIG. 3). The sensor adjustment data includes, for example, ratio / bias data and correction data for straight line correction. The reading of the sensor ID (identification information) data and the sensor adjustment data is not an essential process in the present invention.

  Next, the AD conversion unit 13 of the AD module 1 converts the analog signal (for example, 4-20 mA current signal) received from the sensor 3 via the communication / power supply / reception female connector 10 into digital data (FIG. 3, step S101). .

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

  As the correction processing, the value indicated by the digital data to be corrected is multiplied 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 data. There is a process for straight line correction. As is clear from the above description, this correction process is not essential in the present invention.

  Next, the encryption unit 140 of the AD module 1 encrypts the digital data after AD conversion (step S104 in FIG. 3) and writes the encrypted digital data in the memory 15 (step S105 in FIG. 3). The encrypted digital data may be written to the memory 15 by overwriting and saving the encrypted digital data of one sample before with the latest encrypted digital data, or additionally saving by adding the latest encrypted digital data. But it's okay.

  The AD module 1 is detached from the NW module 2 until the communication / reception / feeding male connector 30 of the sensor 3 is disconnected from the communication / reception / feeding female connector 10 and the connection with the sensor 3 is released, for example. Or until the NW module 2 is removed from the power supply 4 and the power supply is lost (YES in step S106 in FIG. 3), the processes of steps S101 to S105 are repeated.

The AD module 1 may be provided with the time stamp adding unit 145 to add the time stamp indicating the current time to the digital data after AD conversion.
Further, the AD module 1 may be provided with the temperature data addition unit 146, and the temperature data indicating the ambient temperature measured by a temperature sensor (not shown) may be added to the digital data after AD conversion.
Further, the AD module 1 may be provided with a position data adding unit 147 to add position data indicating the current position measured by a GPS (Global Positioning System) sensor (not shown) to the digital data after AD conversion.

  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 essential, and the sensor 3 may be operated by the power source of the sensor itself.

  FIG. 4 is a flowchart illustrating a communication process of the AD module 1 and the NW module 2. When the data transmission unit 141 of the AD module 1 receives the 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. 4), the data transmission unit 141 encrypts the data from the memory 15. Digital data is read (step S201 in FIG. 4), 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. 4).

  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, the encrypted digital data is saved in the memory 15. All encrypted digital data being transmitted is transmitted. Note that the data additionally stored in the memory 15 may be deleted after the transmission.

  When the parameter setting unit 144 of the AD module 1 receives the AD conversion parameter setting data from the NW module 2 via the communication / power supply / reception male connector 11 and the USB controller 12 (YES in step S203 in FIG. 4), the AD conversion parameter is set. Settings are made (step S204 in FIG. 4). The AD conversion parameter at this time includes, for example, the sampling cycle of the AD conversion unit 13.

  The AD module 1 performs steps S200 to S204 until, for example, the AD module 1 is removed from the NW module 2 or the NW module 2 is removed from the power source 4 and power supply is stopped (YES in step S205 in FIG. 4). Repeat.

  Next, the configuration of the NW module 2 will be described with reference to FIG. The NW module 2 controls transmission / reception of signals through the communication / power supply / reception female connector 20, the communication / power supply / reception male connector 21, the antenna 22, and the communication / power supply / reception female connector 20 or the communication / power supply / reception male connector 21. A USB controller 23, a CPU 24, a memory 25, a communication circuit 26 for wireless communication, a communication connector 28, and a communication circuit 29 for wired communication are provided.

  As in the case of the AD module 1, the power supply line of the NW module 2 is connected to the positive power supply terminal (VBUS) of the communication / power supply / reception female connector 20 and the positive power supply terminal (VBUS) of the communication / power supply / reception male connector 21. 5), and a negative side power supply line connecting the GND terminal of the communication / power supply / reception female connector 20 and the GND terminal of the communication / power supply / reception male connector 21. In, the description of the power line on the negative side is omitted.

The CPU 24 executes the processing described in the present embodiment according to the program stored in the memory 25, and functions as the data reading unit 240, the communication unit 241, the data receiving unit 242, and the parameter setting unit 243.
The USB controller 23, the CPU 24, the memory 25, and the communication circuit 26 operate by receiving power supply from the communication / power supply / reception male connector 21 or the communication / power supply / reception female connector 20.

  FIG. 6 is a flowchart for explaining the communication processing of the NW module 2 with the AD module 1. The data reading unit 240 of the NW module 2 transmits a data transfer request to the AD module 1 via the USB controller 23 and the communication / power supply / reception female connector 20 (step S300 in FIG. 6). As described above, the encrypted digital data is transmitted from the AD module 1 in response to the data transfer request.

  When the data reading unit 240 receives the encrypted digital data from the AD module 1 through the communication / power supply / reception female connector 20 and the USB controller 23 (YES in step S301 in FIG. 6), the encrypted digital data is written in the memory 25. (FIG. 6 step S302).

  Next, when the communication parameter setting of the NW module 2 is necessary (YES in step S303 of FIG. 6), the parameter setting unit 243 of the NW module 2 sets the communication parameter to the communication circuit 26 or the communication circuit 29 (step S303). 6 step S304). When the parameter setting of the AD module 1 is necessary (YES in step S303), the parameter setting unit 243 sends the AD conversion parameter setting data to the AD module 1 via the USB controller 23 and the communication / power supply / reception female connector 20. It is transmitted (step S304). The case where communication parameter setting is necessary is, for example, when communication parameter setting data is received from the cloud server as described later. Further, the case where the parameter setting of the AD module 1 is necessary is the case where the AD conversion parameter setting data is received from the cloud server. By transmitting the AD conversion parameter setting data to the AD module 1, the AD conversion parameters are set in the AD module 1 as described above.

  The NW module 2 is removed from the power supply 4 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 released. The processing of steps S300 to S304 is repeated until the power supply is stopped (YES in step S305 of FIG. 6).

  FIG. 7 is a flowchart illustrating the communication processing of the NW module 2 with the network. At the transmission timing of the encrypted digital data (YES in step S400 of FIG. 7), the communication unit 241 of the NW module 2 retrieves the encrypted digital data from the memory 25 and passes it to the communication circuit 26. The transmission timing of the encrypted digital data is, for example, the timing when the encrypted digital data is stored in the memory 25 and can be transmitted. It goes without saying that the encrypted digital data taken out from the memory 25 disappears when it is taken out 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 wireless signal from the antenna 22 to a predetermined cloud server on the network (step S401 in FIG. 7). The wireless communication standard of the communication circuit 26 includes, for example, LPWA (Low Power Wide Area) and 4G, but the present invention is not limited to these wireless communication standards.

  Further, the data receiving unit 242 of the NW module 2 receives the parameter setting data (communication parameter setting data or AD conversion parameter setting data) from the cloud server on the network via the antenna 22 and the communication circuit 26 (FIG. 7). If YES in step S402), the parameter setting data is passed to the parameter setting unit 243 (step S403 in FIG. 7). Thereby, the communication parameter setting or the AD conversion parameter setting is performed as described above.

  The NW module 2 is removed from the power supply 4 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 released. Until the power supply is stopped (YES in step S404 in FIG. 7), the processes of steps S400 to S403 are repeated.

  In the present embodiment, the encrypted digital data received from the AD module 1 is 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 make it transmit without it.
