Abstract

A centrifuge includes: a driving unit; a rotor configured to be rotated by the driving unit and hold a sample; a control unit configured to control rotation of the driving unit; and a communication controller configured to communicate with an external network. The control unit has an automatic transmission mode in which operation data is collected at predetermined intervals while the centrifuge is operating and the operation data is periodically transmitted to a data managing apparatus through the network.

First claim

What is claimed is:

1. A centrifuge comprising:
a driving unit;
a rotor configured to be rotated by the driving unit and hold a sample;
a control unit configured to control rotation of the driving unit; and
a communication controller configured to communicate with an external network,
wherein the control unit has an automatic transmission mode in which operation data is collected at predetermined intervals while the centrifuge is operating and the operation data is transmitted to a data managing apparatus through the network,
wherein the control unit is configured such that specific event data pertaining to a specific event, including time information indicative of when the operation data is transmitted from the control unit, is automatically transmitted to the data managing apparatus,
wherein the operation data is automatically transmitted without receiving a command for request of transmission of the operation data from the data managing apparatus,
the operation data including (i) rotation speed of the rotor, (ii) time information indicative of when set rotation speed is reached after acceleration of the rotor, and (iii) time information indicative of when the rotor starts decelerating,
wherein the operation data is transmitted at a predetermined interval and the specific event data is transmitted at the time the specific event occurs,
wherein the operation data is unconditionally transmitted to the data managing apparatus when the specific event occurs, and
wherein the specific event is one or more of (i) operation start of the rotor based on selection of a start button, (ii) reaching the set number of rotations after acceleration of a rotor, (iii) start of deceleration of the rotor using a stop button, (iv) start of deceleration of the rotor when a set time has elapsed, (v) occurrence of a certain error, (vi) stopping of the rotor after deceleration of the rotor, (vii) door open, (viii) door close, (ix) vacuum pump ON, (x) vacuum pump OFF, (xi) control state change caused by changing of operational conditions during the operation, (xii) login of a user to the centrifuge, or (xiii) logout.

2. The centrifuge according to claim 1 , wherein whether to set the automatic transmission mode or not is selectable in the centrifuge.

3. The centrifuge according to claim 2 , wherein the control unit detects whether or not the network is in a communicable state, and sets the automatic transmission mode to on so that the operation data is transmitted if the network is in a communicable state.

4. The centrifuge according to claim 3 , wherein the control unit detects whether or not the network is in a communicable state, and sets the automatic transmission mode to off so that the operation data is not transmitted if the network is not in a communicable state.

5. The centrifuge according to claim 3 , wherein the operation data transmitted to the network includes unique information regarding a transmission source.

6. The centrifuge according to claim 5 , wherein the unique information is a unique address on the network assigned to the centrifuge.

7. The centrifuge according to claim 4 , wherein the operation data transmitted to the network includes unique information regarding a transmission source.

8. The centrifuge according to claim 7 , wherein the unique information is a unique address on the network assigned to the centrifuge.

9. The centrifuge according to claim 6 , wherein the control unit transmits the operation data at fixed intervals until the centrifuge is powered off after the centrifuge is powered on.

10. The centrifuge according to claim 1 , wherein
the control unit is configured to determine whether the automatic transmission mode is valid,
when the control unit determines that the automatic transmission mode is valid, the control unit automatically transmits the operational data without receiving the command, and
when the control unit determines that the automatic transmission mode is not valid, the control unit does not automatically transmit the operational data without receiving the command.

11. The centrifuge according to claim 1 , wherein
the control unit is configured to determine whether a communication between the centrifuge and the data managing apparatus is possible,
when the control unit determines that the communication is possible, the control unit automatically transmits the operational data without receiving the command, and
when the control unit determines that the communication is not possible, the control unit does not transmit the operational data without receiving the command.

12. A centrifuge operation information collecting system comprising:
a plurality of centrifuges, each of which includes: a driving unit; a rotor configured to be rotated by the driving unit and hold a sample; a control unit configured to control rotation of the driving unit; and a communication controller configured to communicate with an external network and transmit operation data from the control unit at predetermined intervals; and
a data managing apparatus which receives and records specific event data from the centrifuges, the specific event data pertaining to a specific event, including time information indicative of when the operation data is transmitted from the control unit, the operation data including (i) rotation speed of the rotor, (ii) time information indicative of when set rotation speed is reached after acceleration of the rotor, and (iii) time information indicative of when the rotor starts decelerating,
wherein the communication controller is configured to automatically transmit the operation data without receiving a command for request of transmission of the operation data from the data managing apparatus,
wherein the data managing apparatus determines unique information regarding a transmission source from the specific event data transmitted from the centrifuges and records the unique information for every model of the centrifuges,
wherein the operation data is transmitted at a predetermined interval and the specific event data is transmitted at the time the specific event occurs,
wherein the operation data is unconditionally transmitted to the data managing apparatus when the specific event occurs, and
wherein the specific event is one or more of (i) operation start of the rotor based on selection of a start button, (ii) reaching the set number of rotations after acceleration of a rotor, (iii) start of deceleration of the rotor using a stop button, (iv) start of deceleration of the rotor when a set time has elapsed, (v) occurrence of a certain error, (vi) stopping of the rotor after deceleration of the rotor, (vii) door open, (viii) door close, (ix) vacuum pump ON, (x) vacuum pump OFF, (xi) control state change caused by changing of operational conditions during the operation, (xii) login of a user to the centrifuge, or (xiii) logout.

13. The system according to claim 12 , wherein the operation data is transmitted at a predetermined interval and the specific event data is transmitted at the time the specific event occurs.

14. The system according to claim 12 , wherein
the control unit is configured to determine whether an automatic transmission mode is valid,
when the control unit determines that the automatic transmission mode is valid, the control unit automatically transmits the operational data without receiving the command, and
when the control unit determines that the automatic transmission mode is not valid, the control unit does not automatically transmit the operational data without receiving the command.
