摘要:
The invention relates to a system and a method for operating a system, comprising an electric motor fed by a frequency converter via a connecting cable. Arranged on said motor are a signal electronics system, located on the motor side, and at least one sensor, the signals of said sensor being transmitted via the connecting cable to a signal electronics system on the frequency converter side. Said signal electronics system on the frequency converter side has a means for determining the times of switching occurrences, in particular of the controllable switches of the frequency converter and/or the controllable switches of the brake control. Said signal electronics system on the frequency converter side also has a means for generating an interrogation signal which is only sent when a sufficiently long noise-free period of time for the transmission of a protocol can be expected between said times. The signal electronics system on the motor side has a means for transmitting a protocol, said protocol containing information comprising a respective measured value detected by the sensor.

A method, an apparatus, and a system for intelligently controlling a device, and a plug-and-play device are disclosed. The method includes: acquiring, by a controlling device, parameter information of a controlled device in a current state, where the parameter information is used for reflecting a current running state of the controlled device; generating a graphical interaction interface including the parameter information, and sending the graphical interaction interface in a form of a data stream to an interaction device for display; receiving an input event sent by the interaction device, where the input event is triggered by a user based on the parameter information displayed on the graphical interaction interface of the interaction device; parsing the input event to obtain a control instruction corresponding to the parameter information included in the graphical interaction interface; and sending the control instruction to the controlled device, so that the controlled device performs, in response to the control instruction, a control operation corresponding to the current running state of the controlled device. Through embodiments of the present invention, intelligent control on the controlled device can be performed simply, conveniently, and fast, which increases actual utilization of the controlled device and benefits promotion and popularization of the controlled device.

A wireless sensor reader is provided to interface with a wireless sensor. The wireless sensor reader transmits an excitation pulse to cause the wireless sensor to generate a ring signal. The wireless sensor reader receives and amplifies the ring signal and sends the signal to a phase-locked loop. A voltage-controlled oscillator in the phase-locked loop locks onto the ring signal frequency and generates a count signal at a frequency related to the ring signal frequency. The voltage-controlled oscillator is placed into a hold mode where the control voltage is maintained constant to allow the count signal frequency to be determined. The reader uses an ambient reading or other information to select a subset of the possible ring signal frequencies, and tunes or adjusts its circuits and algorithms to focus on that subset.

Es wird ein Verfahren zum Übertragen von Informationen eines Akkupacks (100) an ein angeschlossenes elektrisches Gerät (200, 300) beschrieben, wobei eine Basisinformation des Akkupacks (100) in Form eines bestimmten Spannungswertes eines analogen Spannungssignals (500) über eine Kommunikationsschnittstelle (133, 233) an das elektrische Gerät (200, 300) übertragen wird. Dabei wird das analoge Spannungssignal (500) moduliert und mithilfe des modulierten Spannungssignals (520) eine Zusatzinformation des Akkupacks (100) zusätzlich zu der Basisinformation über die Kommunikationsschnittstelle (133, 233) an das elektrische Gerät (200, 300) übertragen.

A measurement system may comprise a sensor wire and a transceiver unit. The sensor wire may comprise an insertable portion configured to be inserted in a blood vessel of a patient's body and a first sensor and a second sensor disposed within the insertable portion at a distal end of the sensor wire. The sensors are configured to measure parameters when inserted inside the patient. The transceiver unit may comprise: a housing adapted to be connected to a proximal end of the sensor wire; and a first communication module within the housing adapted to wirelessly communicate by a communication signal with an external second communication module in order to transfer information to the external second communication module.
