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.
Claims15
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.
