Abstract:
1. A method of electronically recording a history of a bioreactor control process, the method comprising: monitoring a condition in a bioreactor in accordance with the bioreactor control process; receiving, in a utility tower, sensor data related to the condition in the bioreactor, the bioreactor located external to the utility tower; calculating information using the sensor data; sending the information related to the sensor data from the utility tower to a controller over a first communication network; receiving in the controller the sensor data from the utility tower; determining, in the controller, control signals to carry out the bioreactor control process, the control signals based on at least the information received from the utility tower; sending a first control signal from the controller to one of a gas control system and a pump control system housed in the utility tower over a second communication network to add a substance to or remove a substance from the bioreactor; changing, in response to the first control signal communicated from the controller to the utility tower, the contents in the bioreactor by supplying a substance to the bioreactor from a supply system or removing a substance from the bioreactor; sending a second control signal from the controller to the utility tower over the second communication network to agitate a solution in the bioreactor; agitating the solution in the bioreactor in response to the second control signal communicated to the utility tower over the second communication network; and recording an electronic history of the bioreactor control process performed in the bioreactor, wherein supply or removal of the substance in the bioreactor in response to the information related to the sensor data is under the control of the first control signal from the controller to the utility tower.
