Electromagnetic valve assembly with monitoring unit for fault detection
A recently granted patent (Publication Number: US11946652B2) discloses an assembly comprising an electromagnetic valve with a magnetic coil, a valve element, and a movable element. The magnetic coil, when energized, moves the movable element in one direction to shift the valve element from an initial position to an active position. The patent also includes a control circuit with various components such as an output device, monitoring unit, signal amplifier, safety device, and a control unit for managing the current source and connection to the magnetic coil.
Furthermore, the patent describes a gas burning system incorporating a gas burner, gas supply line, ignition element, and an electromagnetic gas valve for regulating gas flow. The system utilizes the control circuit from the patent to operate the electromagnetic gas valve efficiently. Additionally, a method for monitoring the switching state of the electromagnetic valve is detailed, involving measuring voltage and current levels, detecting signal peaks, and determining fault states based on current or voltage characteristics. The method also includes transmitting fault messages and inferring movement failures of the valve element, providing a comprehensive approach to monitoring and maintaining the gas burning system's functionality.
