DETAILED DESCRIPTION OF THE INVENTION

[0040] A motorized pump, typically called a sump pump, is often positioned in a cylindrical pit formed in the floor of a basement or crawl space of a dwelling or other building. Drainage tile is typically positioned around the inner and/or, outer periphery of the foundation of the dwelling and is connected to the pit so that the accumulated subterranean water is directed into the pit. The sump pumps may fail causing flooding in the basement and, if the basement is finished, great damage. The motor may fail, the power may be interrupted, the pump may fail, the water conduits may be obstructed or disconnected and the pump needs may exceed the capacity of the system in extreme weather conditions.

[0041] While the status of the pump can be monitored by the homeowner when he/she is there, if the homeowner is gone, the damage from a failed pump may be extensive as no one will know it has failed. Further, if the home is repaired after a pump failure that had caused great damage, a prospective new homeowner will not be able to know of the pump failure and potential long term damage to the home that is masked by the repair. Due to costs involved with the consequences of sump pump failure proved, improved monitoring of sump pump operation is desirable in sump pumps and other fluid moving devices powered by electric motors. The methods, systems, and apparatus described herein facilitate improved monitoring of an electric machine. This disclosure provides designs and methods to improve monitoring of such motors.

[0063] It should be appreciated that the sensor 22 may include the controller 54 or that the controller 54 may include a sensor 22 and/or other sensors.

[0064] It should be appreciated that the sensor 22 may be positioned anywhere in the fluid collection system 36 or in the information collection system 10. Typically the sensor 22 is positioned in or adjacent the location of the object or phenomenon. For example, if the sensor 22 is configured to measure the fluid 14, the sensor may be positioned in or adjacent the pump 12, the drainage system 16 and/or the discharge plumbing 48. For example, if the sensor 22 is configured to measure the electrical energy conveyed in the electrical lines 53, the sensor may be positioned in or adjacent the electrical lines 53.

[0065] The information collection system 10 of the present invention may be utilized to collect information or input 11 related to the fluid collection system 36 for storage and later retrieval for any of a number of purposes and/or to collect information or input 11 related to the fluid collection system 36 over time and to process that information to make adjustments over time to the operation of the fluid collection system 36.

[0066] Continuing to refer to FIG. 1, the information collection system 10 of the present invention may be utilized to collect information or input 11 related to the fluid collection system 36 for storage and later retrieval by first collecting input 11 from the sensor 22 and converting that input 11 to an electric input signal 56 that is transmitted to the control module 54. The electric input signal 56 or an equivalent signal is sent on to the information collection device 26 within the control module 54. The information collection device 26 passes the electric input signal 56 or an equivalent signal on to the information storage device 28 within the control module 54. When input 11 from the sensor 22 corresponding to the electric input signal 56 is desired, the retrieval device 30 is utilized to retrieve the input 11 corresponding to the electric input signal 56.

[0068] Continuing to refer to FIG. 1, the information collection system 10 of the present invention may be utilized to collect information or input 11 related to the fluid collection system 36 over time and to process that information to make adjustments over time to the operation of the fluid collection system 36. First input 11 is collected from the sensor 22 and converted to an electric input signal 56 that is transmitted to the control module 54. The electric input signal 56 or an equivalent signal is sent on to the information collection device 26 within the control module 54. The electric input signal 56 is passed by the information collection device 26 as the electric input signal 56 or an equivalent signal on to the information storage device 28 within the control module 54. The controller then utilizes the electric input signal 56 as an input in an algorithm and later sends a command signal 58 to the motor 34 to provide a changed operation of the motor 34 of the fluid collection system 36.

[0069] The information collection system 10 may further include a clock 60 operably connected to the information storage device 10. The information storage device 10 and the clock 60 may be configured to provide historical data related to the operational information. The electric input signals 56 may be tagged with times provided by the clock 60 to provide each signal 56 with the exact time it was generated.

[0070] The information collection system of the present invention may be utilized to collect information or input related to the fluid collection system over time. The information collection system may be used to compile information or data about the use of a device, such as a sump pump.

[0071] The information, for example and as shown in FIG. 4, may include, for example, pump motor current, pump motor voltage, pump motor temperature, pump flow, pump pressure, pump temperature, float level.

[0072] This information may be used by the homeowner to monitor the sump pump. Measuring pump flow or current, for example, may be used to determine the use of the motor and possible preventive maintenance of the sump pump or motor.

[0073] This information may also be used by a prospective home buyer to verify that the basement or crawl space has been continuously protected by a sump pump and that the basement or crawl space has not been subjected to a flood that might have caused undetectable damage such as mold or rot.

[0074] For example and as shown in FIG. 5, the compile information or data about the use of a device may be provided in graphical form so that the homeowner or prospective buyer can quickly view the history of the use of the sump pump.

[0075] While the information collection system of the present invention may be utilized to operate the fluid collection system independently of other input external to the fluid collection system, the information collection system may interact with external inputs to enhance the operation of the fluid collection system and to enhance the input that may be collected by the information collection system.

[0076] For example and referring now to FIG. 2C, information collection system 10C of the present invention may be utilized to collect information 11C from a plurality of spaced apart fluid collection systems, for example first fluid collection systems 36C1, second fluid collection systems 36C2 and third fluid collection system 36C3.

[0079] The information collection system 10C may further include a comparing device 72C for comparing the operation information 66C with the comparison information 70C. It should be appreciated that the comparing device 72C may include a computer or controller 74C that may provide optimum command signals 58C for each of the fluid collection systems 36C.

[0080] The information retrieval device 30C of the information collection system 10C may send data signals 78C to the modem 31 or to a data service 33C which may be access by a user 35C that may or may not be related to a sump pump installation.

[0081] It should be appreciated that the information collection system 10C may be provided such that optimum command signals 58C are formulated by having the comparing device 72C perform an evaluation 76C of the operation information 66C based at least in part on the comparison information 70C.

[0082] It should be appreciated that the information collection system 10C may be provided such that the evaluation 76C includes at least one of the relative state of the buildings drainage system and the effectiveness of the buildings drainage system.

[0083] Referring now to FIGS. 6 and 7, the information collection system 10C may be utilized to collect information, data or input related to the fluid collection systems over time and over a wide range of locations. This data over time may be processed and made available to a wide variety of potential users including the sump pump owners as well as other individuals who would benefit from such data.

[0084] The information collection system may be used to compile information or data about the use of the networks of sump pumps located at in many locations.
