Methods for determining an absolute position of a moving travel unit of a stationary transport system, the travel unit movable along a travel path inside the system. The travel unit is driven by at least one linear motor along the path. The linear motor is a synchronous motor including a plurality of stator units installed along the travel path configured to provide a magnetic field traveling along the travel path. At least one rotor unit is attached to the travel unit and is configured to be driven along the travel path by the traveling magnetic field. Wherein respectively by analysis of regulating parameters of a vector regulation of the linear motor an active stator unit is determined from the plurality, which presently provides the magnetic field driving the rotor unit and a relative position of the rotor unit in relation to the active stator unit is computed.

The present invention relates to a conveyor system comprising: a drive machine, a conveyor control unit configured to control operation of a conveyor device, a sensor array comprising at least one sensor mounted to the drive machine and adapted to measure one or more properties of the drive machine, a processing unit associated with the drive machine, wherein the processing unit is connected to the sensor array and configured to obtain and process measurement data from the sensor array to generate in-formation about an operation of the drive machine, and a communication channel between the conveyor control unit and the processing unit. The conveyor system may be an elevator system, an escalator system or a moving walk system.

The present invention relates to an overspeed and reverse drive preventing device for an escalator. The device has a pawl and a connection part mounted to be connected by a tension spring such that, when the pawl is inserted into gears of the ratchet and is compressed by a ratchet, the tension spring is extended and the pawl is perfectly inserted into the ratchet, thereby making it possible to apply the same to escalators having various specifications. A braking member is mounted on the inner peripheral surface of a brake arm mounted outside a ratchet part or a rotary shaft, or on the outer peripheral surface of the device facing the brake arm. Therefore, the overspeed and reverse drive preventing device can apply additional braking power to the escalator rotary shaft to prevent a damage of a brake lining mounted on the ratchet part, prevent overspeed or reverse rotation of the escalator even though the brake lining is damage so as not to show the braking power, and reduce installation expenses and period of time and prevent deterioration in durability caused by perforation work since there is no need to perform perforation work to the escalator rotary shaft and the escalator support frame.
