摘要

The invention relates to a profiled locking cylinder comprising a cylinder housing and at least one key-actuated cylinder core or cylinder insert, in addition to a locking bit, said cylinder housing being equipped with several pin tumblers. According to the invention, the pin tumblers can be displaced by means of electromagnetic actuators that are located in the cylinder insert and the actuators are activated in a wireless manner. At least one of the end faces of the cylinder insert consists of a ceramic material or is connected in a positive and/or material fit to a ceramic cap. The invention also relates to a method for increasing the interference and transmission security during the provision of data by means of wireless, in particular high-frequency networks, preferably for controlling, programming, monitoring and evaluating locking systems comprising electromechanical actuation. According to the invention, the receivers that are addressed via the network comprise at least two antennae that are located at a distance and have predefined alignment characteristics and/or sensitivities. The authorised transmitter devices and repeaters that are required to carry out the data transmission are installed and/or operated at predetermined locations. The receiving level and/or angle of incidence in the authorised transmission operation are determined in a calibration phase and are stored with a reference to the receiver for the subsequent authentication of the respective transmitter devices on the receiver side or in a higher level evaluation device that interacts with the receivers. With each renewed data transmission, the stored standard level and/or standard angle of incidence is/are compared with the current respective values and the data transmission is released in accordance with the degree of concordance in the comparison step.
