    • A system for providing wire-free and contact free electric power and communication connection in a security installation between a door and a frame. The cores, windings, and control circuits of first and second portions of a split core transformer are disposed in the frame and the door, respectively. Power applied to the first portion induces a voltage and current in the second portion when the door is in a closed position. Modulation of the voltage amplitude in either the first or second portion defines a communication signal between the door and the frame. Status and data are transmitted at data rates that are essentially twice the frequency of the voltage applied to the split core transformer. In a second embodiment, voltage transfer occurs at 20 KHz and data transfer is in the range of 100K baud.
    • 一种用于在门和框架之间的安全装置中提供无线和无接触电力和通信连接的系统。 分裂铁芯变压器的第一和第二部分的铁芯,绕组和控制电路分别设置在机架和门中。 当门处于关闭位置时,施加到第一部分的电力在第二部分中引起电压和电流。 在第一或第二部分中的电压振幅的调制限定门和框架之间的通信信号。 状态和数据以基本上是施加到分离式磁芯变压器的电压频率的两倍的数据速率传输。 在第二实施例中,电压传输发生在20KHz,数据传输在100K波特的范围内。
