摘要： A data error detection method for a bit, byte or word oriented network wherein a protected data unit 46 and an associated data check unit 50 are addressed to a particular field device located on the network, 10 or 26. The data check unit 50 is derived in a particular manner either solely from the protected data unit 46 or from the protected data unit 46 and particular binary codes representing attributes of the network 10 or 26 and the field device sending the protected data unit 46. The particular configuration of the checking data unit 50 is such that the receiving field device or the host 22 can perform a bit-by-bit comparison of either the received protected data unit 46 or data check unit 50 with a protected data unit 46 or data check unit 50 derived in the particular manner by the receiving host 22 or field device 14 or 18.

摘要： A DC motor phase detection algorithm that monitors the change in motor current to detect pulses in the current caused by the motor's commutator brushes crossing over the gap between rotor commutator segments as the motor shaft rotates. A pulse is generated each time a commutator brush breaks and then reconnects to a commutator segment. The algorithm detects and counts the pulses in order to determine the number of revolutions the shaft has rotated. The motor phase can then be used to determine the distance, rotational or linear, that the moving portion of the load attached to the motor has traveled. If the initial position of the moving portion of the device is known then the absolute position can be calculated.

摘要： An algorithm for verifying the state of switches (such as in a transfer switch mechanism) and for controlling the switches. The control algorithm controls automatic actuation of the switches. The verification algorithm measures the instantaneous voltage on the source and load sides of one or both switches and calculates the RMS magnitude, period, and relative phase for each voltage measurement. If the voltage characteristics for the load do not match any of those for any source, an error is outputted. If the voltage characteristics of the sources match each other, the algorithm determines that they are synchronized. The algorithm determines which switch is closed by comparing the voltage characteristics of the load and of each source, and if there is a match, then the switch associated with the source that is matched with the load is determined to be closed. Otherwise, the switch is determined to be opened.

摘要： In a distributed control system where multiple controllers can control the same actuator or sensor, each controller is assigned a priority level, and command arbitration is based on the relative priority levels of the controllers. Each actuator or sensor selects a controller to serve as a master controller for one or more of its state variables. Different master controllers may be selected for different state variables. When a command is received by the actuator or sensor, it determines how to treat the command by comparing the priority of the controller from which the command originated to the priority of the master controller.

摘要： A DC motor mechanical shock protection system monitors the motor current to determine the torque the motor is applying to the gearbox, and takes mitigating action if the torque approaches a level that can damage the driven device and/or the drive system. This protects the system from mechanical shock without limiting the available torque during normal operation. The change in motor current is monitored to detect the inertial torque before the elasticity between the motor and the driven device is fully compressed and the motor mounting or gearbox begin to be damaged.
