  FIG. 1 is a schematic diagram showing a configuration of a container 10 to which a culture container detection unit 1 according to the present embodiment is attached. FIG. 1A is a cross-sectional view showing a state where a plate body 30 and a lid 20 are separated. (B) is a side view showing a state in which the lid 20 is placed on the dish body 30. FIG. 2 is a plan view showing the configuration of the culture container detection unit 1. FIG. 3 is a block diagram showing the configuration of the non-contact power transmission system according to the present embodiment. FIG. 4 is a perspective view showing the configuration of the coil in the present embodiment. FIG. 5 is a circuit diagram showing the relationship of the coils in the present embodiment.

  As shown in FIG. 1, the container 10 includes a cylindrical dish body 30 having a bottom surface and a transparent through-hole, and a cylindrical lid body having a ceiling surface that covers and covers the top of the dish body 30. Part 20. The container 10 is, for example, a petri dish for performing culture. The dish body 30 is filled with a culture solution 35 that is a culture medium. In order to observe the culture, the dish body 30 and the lid part 20 are preferably formed of glass or a synthetic resin material that allows the inside to be seen through. In this specification, “the inside can be seen through” means a state in which the inside of the container 10 can be visually observed from the outside, such as transparent or translucent.

  The culture container detection unit 1 according to the present embodiment is attached to the above-described container 10 and accurately detects the culture environment inside the container 10 without opening the lid 20, so that an external computer or tablet terminal is used. Can be sent to etc. The culture container detection unit 1 includes a control module 50, a coil unit 40, and an antenna 60 that are attached to the lower surface 25 of the inner surface of the lid 20, and an environmental sensor that is disposed inside the container 10.

  The coil unit 40 is an example of a power feeding unit, and the antenna 60 is an example of a transmission unit. As the environmental sensor, a gas sensor 52 and a pH sensor 55 are used. In addition to the sensors described above, various sensors that can detect the environment in the container 10 such as a temperature / humidity sensor and a resistance sensor are applied to the environment sensor.

  A coil portion 40 is provided on the lower surface 25 which is a part of the inner surface of the lid portion 20. As shown in FIG. 4, the coil unit 40 includes a power receiving coil 41 and a load matching coil 42 that are stacked along the height direction Z of the container 10. The coil part 40 is arranged around the center part of the lower surface 25 of the lid part 20. The coil part 40 is formed by adhering a spirally wound conducting wire to the lid part 20, and also formed as a conductive ink printing pattern, a flexible printed circuit board, or a conductive pattern formed by thin film formation or surface treatment. You can also In the present embodiment, a power receiving coil 41 and a load matching coil 42 in which a conductive pattern is formed on a base material 43 that is a flexible substrate are used. The power receiving coil 41 is supplied with power by energizing a power supply coil 90 (FIG. 7) provided in a non-contact manner with the power receiving coil 41 outside the container 10.

  The power feeding unit may include a secondary battery 45 in addition to the power receiving coil 41. The secondary battery 45 is disposed on, for example, the coil unit 40 inside the container 10 and is charged using the received power by the power receiving coil 41.

  The control module 50 and the antenna 60 are electrically connected to each other, and are fixed on the coil portion 40 by adhesion. The control module 50 is electrically connected to the coil unit 40.

  As shown in FIG. 2, in a state before the culture container detection unit 1 is attached to the container 10, for example, a coil portion 40 is formed on a circular base material 43 having a hole in the center and extends from the base material 43. A pH sensor 55 is attached to the distal end portion of the extending portion 44. A conductor pattern is formed on the extending portion 44, and the pH sensor 55 and the control circuit 51 are electrically connected via the conductor pattern.

  In the culture container detection unit 1 before being attached to the container 10, the extending portion 44 may be flat. When attaching the culture container detection unit 1 to the container 10, the extension portion 44 is connected to the line L <b> 1 and the line L <b> 2 in a state where the base material 43 on which the coil portion 40 is formed is fixed to the lower surface 25 of the lid portion 20 by adhesion. Each is bent about 90 degrees. As a result, as shown in FIG. 1A, the extending portion 44 extends downward from the lower surface 25 of the lid portion 20, and the pH sensor 55 is bent substantially parallel to the lower surface 25. That is, the pH sensor 55 is disposed at a position away from the lower surface 25 of the lid 20.

  As shown in FIG. 1 (B), when the lid portion 20 to which the culture vessel detection unit 1 is attached is placed on the plate main body 30, the pH sensor 55 attached to the tip of the extending portion 44 becomes the plate main body. It comes into contact with 30 culture fluids 35. Thereby, the pH (hydrogen ion concentration index) of the culture solution 35 can be directly detected.

  As illustrated in FIG. 3, the control module 50 includes a control circuit 51 that controls each unit as a control unit, and a gas sensor 52 that is an example of an environmental sensor. In the present embodiment, the control circuit 51 may include a voltage detection unit 511 and a switching unit 512. The voltage detection unit 511 detects the power reception voltage of the power reception coil 41. The switching unit 512 switches the power supply source based on the voltage value detected by the voltage detection unit 511.

  In the present embodiment, when the voltage value detected by the voltage detection unit 511 is equal to or greater than a preset value (power reception reference value), the switching unit 512 selects the power reception coil 41 as a power supply source. Accordingly, a predetermined load (for example, the gas sensor 52 or the antenna 60) is operated by the power supplied from the power receiving coil 41. Further, the secondary battery 45 is charged by the power supplied from the power receiving coil 41.

  On the other hand, when the voltage value detected by the voltage detection unit 511 is lower than the power reception reference value, the switching unit 512 selects the secondary battery 45 as the power supply source. Accordingly, a predetermined load (for example, the gas sensor 52 or the antenna 60) is operated by the power supplied from the secondary battery 45. When the voltage value detected by the voltage detection unit 511 is lower than the power reception reference value, the switching unit 512 may select both the power reception coil 41 and the secondary battery 45 as power supply sources. Thereby, each of the power receiving coil 41 and the secondary battery 45 is configured to supplement each other's electric power.

  Further, the voltage detection unit 511 may further detect the voltage of the secondary battery 45. In this case, the switching unit 512 adjusts the balance of the supply source that supplies power to the load based on the received voltage of the power receiving coil 41 and the voltage value of the secondary battery 45 detected by the voltage detecting unit 511, The power allocated for charging the secondary battery 45 can be adjusted.

  The non-contact power transmission system according to the present embodiment includes a container 10 to which the culture container detection unit 1 is attached and a power supply apparatus 100 that supplies power to the container 10 in a non-contact manner.

  As described above, the control module 50 mounted on the culture vessel detection unit 1 includes the control circuit 51, the gas sensor 52 and the pH sensor 55 as environmental sensors. The control circuit 51, gas sensor 52, pH sensor 55, and antenna 60 are operated by at least one of the power supplied to the power receiving coil 41 and the power of the secondary battery 45.

The gas sensor 52 detects the gas concentration (for example, CO ₂ concentration) in the container 10 and outputs it to the control circuit 51. The pH sensor 55 is in contact with the culture solution 35 and detects the pH of the culture solution 35. The control circuit 51 records the detection results by the gas sensor 52 and the pH sensor 55 and the ID information set for each container 10 from the antenna 60 to the ID reader 92 through the antenna 93 of the power feeding apparatus 100. For example, the antenna 60 modulates and transmits a high-frequency carrier signal with a signal corresponding to the detection result of the gas sensor 52 and the pH sensor 55 and the ID information. The time interval for recording a signal from the antenna 60 to the ID reader 92 and the ID information are stored in advance in the storage unit of the control circuit 51.

  Moreover, it is preferable to provide the control module 50 with an indicator indicating that the power from the power supply apparatus 100 is being received. Providing this indicator is preferable because it is possible to replace the container 10 that cannot receive power due to a failure of the control module 50 or the like. A light emitting diode etc. are used for an indicator.

  In the power supply apparatus 100, information received by the ID reader 92 is stored in the storage unit of the control unit 91. When there is a request for retrieving information stored in the storage unit from an external device to the control unit 91, it can be transmitted to the external device (computer or tablet terminal) by the antenna 93 (wireless device).

  Further, when the power receiving voltage at the power receiving coil 41 becomes lower than the power receiving reference value, such as when the container 10 is separated from the power feeding device 100 or cannot be fed from the power feeding device 100 due to some influence, the secondary battery is switched by the switching unit 512. Switching is performed so that 45 electric power is supplied to the gas sensor 52, the pH sensor 55, and the antenna 60. As a result, even when the power receiving voltage is reduced or no power is received while power is received by the power receiving coil 41, information is detected by the gas sensor 52 and the pH sensor 55 without interruption, and information is received from the antenna 60. Can continue to send.

  In particular, wireless communication requires a predetermined time for pairing. In the present embodiment, even when the container 10 is separated from the power supply apparatus 100, power is supplied from the secondary battery 45, so that wireless communication pairing is maintained and the link is not broken. Therefore, even when power is not supplied from the power supply apparatus 100, environmental information such as the gas concentration inside the sealed container 10 and the pH of the culture solution 35 is not lost without opening the lid 20, and the container 10 is not lost. Changes in environmental information while moving can be monitored.

  The relationship between the power feeding coil 90, the load matching coil 42 on the container 10 side, and the power receiving coil 41 is as shown in FIG.

In the control unit 91 provided in the power supply apparatus 100, the power supplied from the external power supply 110 is supplied (energized) to the power supply coil 90 as an AC voltage V _in having a predetermined waveform (FIG. 5). In the power feeding device 100, an oscillation circuit is configured by the power feeding coil (L ₁ ) 90, the capacitor C ₁ and the winding resistance r ₁ , and an alternating current having a predetermined frequency (1 MHz or less) is applied to the power feeding coil (L) 90. It is done. Capacitor C ₁ and winding resistance r ₁ are arranged in power supply apparatus 100.

On the container 10 side, a resonance circuit is configured by the load matching coil (L ₂ ) 42, the resonance capacitor C _2, and the winding resistance r ₂ , and the power receiving coil (L ₃ ) 41 includes the winding resistance r ₂ and the control module. Connected to a load _RL such as 50. On the container 10 side, the resonant capacitor C ₂ , the winding resistance r ₂ , the load R _L , and the winding resistance r ₃ are arranged in the control module 50.

In this configuration, the current magnetic field M ₁₂ is induced by an AC signal applied to the power feeding coil 90. The current magnetic field _{M 12,} the resonance is generated given the load matching coil _(L 2) 42, the induced magnetic field _{M 23} by the resonance is supplied to the power receiving coil 41, power is supplied to the load _{R L.}

  Since the power supply coil 90 and the load matching coil 42 are matched in impedance and supplied to the power receiving coil 41, power corresponding to the power supplied to the power supply coil 90 can be efficiently transmitted to the power receiving coil 41. That is, by using the load matching coil 42, it is possible to optimize the load characteristics. In particular, when power is supplied to the plurality of power receiving coils 41 with one power supply coil 90, mutual interference does not occur. The overall Q value of the plurality of power receiving coils 41 can be increased while suppressing the Q value to an extent.

  FIG. 6 is a side view showing a state in which the container 10 to which the culture container detection unit 1 according to the present embodiment is attached is stacked on the power feeding apparatus 100. FIG. 7 is a side view showing a state where the container 10 to which the culture container detection unit 1 according to the present embodiment is attached is placed on the power supply apparatus 100.

  As shown in FIG. 6, the container 10 can be stacked by placing a plate body 30 of another container 10 on the lid part 20 on which the coil part 40 is formed. Here, if the fitting part which mutually fits is provided in the upper part of the cover part 20 and the lower part of the plate main body 30, the position of the piled container 10 in the plane direction (direction orthogonal to a height direction) will be decided, and all in a plane direction Since the center positions of the containers 10 coincide with each other, it is possible to more reliably supply power and to reduce the possibility of dropping due to misalignment. The containers 10 stacked in this way are arranged on the mounting surface 101 of the power supply apparatus 100 shown in FIG. Accordingly, the container 10 is stacked in the direction D1 perpendicular to the placement surface 101.

  Four regions 102, 103, 104, and 105 (FIGS. 6 and 7) in which the container 10 is disposed are provided on the mounting surface 101 having a substantially rectangular shape in plan view, and power is supplied to the peripheral portion so as to surround these regions. A coil 90 is formed. The feeding coil 90 is formed by adhering a conductive wire wound in a substantially rectangular shape to the mounting surface 101, and also as a conductive pattern formed by conductive ink printing pattern, flexible printed circuit board, or thin film formation or surface treatment. It can also be formed. Here, the surface including the feeding coil 90 and the surface including the power receiving coil 41 are parallel. The container 10 may be laid flat without being stacked.

  The power supply device 100 and the container 10 disposed on the power supply device 100 having the above-described configuration constitute a non-contact power transmission system. In the non-contact power transmission system of the present embodiment, by providing the load matching coil 42, even if the containers 10 are stacked, the Q value can be suppressed to a level that does not cause mutual interference for each container. This power can be supplied to the receiving coil 41 of each container.

  FIG. 8 is a perspective view showing a state in which the non-contact power transmission system according to the present embodiment is arranged in the storage 120. The power supply device 100 is placed on the upper surface 122 a of the main body 122 of the storage 120, and the container 10 is stacked on the placement surface 101 of the power supply device 100 in a direction D <b> 1 perpendicular to the placement surface 101. A lid 121 is placed on the main body 122 so as to surround the container 10 and the power supply apparatus 100. The main body 122 is provided with a temperature controller (not shown), and the temperature in the space surrounded by the lid 121 and the main body 122 can be adjusted.

In the container 10 stored in the storage box 120, for example, the CO ₂ concentration is detected by the gas sensor 52, the pH of the culture solution 35 is detected by the pH sensor 55, and these pieces of information are stored in the storage unit of the control circuit 51. ing. In addition, detection results by the gas sensor 52 and the pH sensor 55 are transmitted to the power supply apparatus 100 together with ID information for each container 10, stored in the storage unit of the control unit 91, and transmitted to the outside by the antenna 93. The external device that has received the data transmitted from the antenna 93 can check the gas concentration inside the container 10 sealed and the pH of the culture solution 35.

  Further, when the container 10 stored in the storage box 120 is taken out and the inside of the container 10 is to be observed with a microscope or the like, power supply cannot be performed by separating the container 10 from the power supply apparatus 100. Even in such a case, in the present embodiment, it is possible to continue supplying power to the gas sensor 52 and the antenna 60 by the secondary battery 45 when the power reception voltage at the power reception coil 41 decreases. Therefore, even if it takes out from the storage 120, the detection of the gas concentration in the container 10 and the pH of the culture solution 35 can be continued.

  When the container 10 stored in the storage 120 is taken out and the inside of the container 10 is observed with a microscope or the like, an RF signal or the like is transmitted between the power supply apparatus 100 and a control circuit unit provided in the microscope. It is necessary to perform matching such as confirmation of ID by performing communication, and then transmit data transmitted from the antenna to the control circuit of the microscope. In the present embodiment, power can be secured in the power feeding apparatus 100 before the container 10 is taken out of the storage box 120 and carried to the microscope. Therefore, matching between the control unit 91 of the power supply apparatus 100 and the control circuit on the microscope side can be completed before the container 10 is taken out from the storage 120 and carried to the microscope, and immediately after the container 10 is installed in the microscope. In addition, communication between the control unit 91 of the power supply apparatus 100 and the control circuit on the microscope side is immediately possible.

  Further, when the power supply source is switched from the power receiving coil 41 to the secondary battery 45, information indicating that the container 10 is separated from the placement surface 101 of the power feeding device 100 is recorded in the storage unit of the control circuit 51, Information that the container 10 is placed on the placement surface 101 of the power supply apparatus 100 when the supply source is switched from the secondary battery 45 to the power receiving coil 41 can also be recorded in the storage unit of the control circuit 51.

  Thereby, it is possible to obtain information as to whether or not the container 10 has been taken out of the storage 120 due to switching of the power supply source and whether or not the container 10 has been returned to the storage 120. With this information, the timing at which the container 10 is taken out from the storage box 120 and the timing at which the container 10 is returned to the storage box 120 is recorded, and the management status of the container 10, the gas concentration in the container 10 associated with the management status, and the culture solution It becomes possible to obtain environmental information such as pH of 35.

With the configuration described above, the following effects are achieved according to the above embodiment.
(1) Since the culture container detection unit 1 is attached to the inside of the container 10, the internal state of the container 10 is detected by the environmental sensor (gas sensor 52 and pH sensor 55) without opening the lid portion 20, and the antenna 60. Can be sent to the outside. Therefore, the state inside the container 10 can be accurately and objectively grasped without changing the environment inside the container 10 and without relying on visual observation.

(2) Since the power receiving coil 41 is disposed at a position avoiding the central portion 22 of the upper surface 21 of the lid portion 20 through which the inside can be seen through, the container 10 can be viewed from above even when the lid portion 20 is placed on the plate body 30. Can be observed inside. Therefore, since the internal environment is not changed by opening the container 10, a more preferable culture environment can be provided.

(3) Since the power receiving coil 41 is provided in each container 10 and the power feeding coil 90 is disposed outside the container 10, power can be supplied to the power receiving coil 41 without contact with the power feeding coil 90. The temperature / humidity management for each container 10 can be accurately performed while ensuring the degree of freedom of arrangement of the container 10.

(4) Desired by forming the receiving coil 41, the load matching coil 42, and the feeding coil 90 with a conductive ink printing pattern, a flexible printed circuit board, or a conductive pattern formed by thin film formation or surface treatment. Can be formed accurately and inexpensively. Thereby, the detection unit 1 for culture vessels can be easily attached using the existing vessel 10.
