Abstract
A pump assembly method and computer program are disclosed. The pump assembly comprises: a pump, an associated motor controller and an accelerometer mounted on the pump. The motor controller is configured to control power supplied to drive the pump and to receive data output from the accelerometer, the motor controller comprising processing circuitry configured to process the data received from the accelerometer to determine accelerations experienced at the pump due to the pump operation. These accelerations can be used to determine a condition of the pump.
Claims16
A pump assembly comprising:
- a pump, an associated motor controller and an accelerometer mounted on said pump;
- said motor controller being configured to control power supplied to drive said pump;
- and
- to receive data output from said accelerometer, said motor controller comprising processing circuitry configured to process said data received from said accelerometer to determine accelerations experienced at said pump due to said pump operation, said processing circuitry being operable to process data received from said accelerometer in conjunction with motor controller data so as to separate acceleration data generated by said pump operation and other signals.
2-38. (canceled)
A method of analysing data received from an accelerometer mounted on a pump comprising:
- receiving data output from said accelerometer;
- receiving motor controller data from a motor controller for controlling a drive motor of said pump;
- and
- processing said acceleration data in conjunction with said motor controller data to determine accelerations experienced at said pump due to operation of said pump,
- wherein said step of receiving data output from said accelerometer comprises sampling data signals output from said accelerometer, said sampling being synchronised with at least one type of said motor controller data.
