Abstract
There is provided a method and system for monitoring the health of a solenoid and controlling the solenoid to compensate for a change in the health of the solenoid due to wear. The system including a sensor for detecting at least one parameter of a motion of the solenoid; and a control system for providing a control signal to the solenoid at a first time point, measuring at least one motion parameter of an actual motion of the solenoid driven by the provision of the control signal, and predicting a remaining life of the solenoid based on a difference between actual and target motion parameters of the motion of the solenoid.
Claims22
A method for monitoring the health of a solenoid, the method comprising:
- measuring a first value of at least one motion parameter of a motion of the solenoid when the solenoid is actuated at a first time point, the actuation of the solenoid being driven by a first control signal that is provided to the solenoid;
- measuring a second value of the at least one motion parameter when the solenoid is actuated at a second time point, the actuation of the solenoid being driven by a second control signal that is provided to the solenoid;
- and
- determining a remaining life of the solenoid based on a failure threshold of the at least one motion parameter and at least one first change trend of the at least one motion parameter;
- generating a first warning signal to indicate that the remaining life is less than an acceptable remaining life of the solenoid.
A system for monitoring the health of a solenoid, the system comprising:
- at least one sensor positioned to detect at least one characteristic of a motion of the solenoid;
- a control system connected to the solenoid and the sensor, the control system including at least one processor, memory in electronic communication with the at least one processor, and instructions stored in the memory that are executable by the at least one processor for:
- providing a first control signal to the solenoid at a first time point for driving a motion of the solenoid;
- receiving from the at least one sensor at least one motion parameter of a motion of the solenoid the motion being driven by the at least one first control signal;
- providing a second control signal to the solenoid at a first time point for driving a motion of the solenoid;
- and
- receiving from the at least one sensor at least one motion parameter of a motion of the solenoid the motion being driven by the at least one second control signal;
- and
- generating a warning signal to indicate that a remaining life is less then an acceptable remaining life of the solenoid, the remaining life being determined based on a failure threshold of the at least one motion parameter and at least one first change trend of the at least one motion parameter.
