    • PURPOSE: A RF transceiver apparatus for loss and robbery prevention is provided, which prevents loss and robbery of an important belonging in advance by outputting an alarm. CONSTITUTION: According to the RF transceiver apparatus performing RF communication using a communication frequency in a specific band, a transmitter(100,200,300) is given with a specific discrimination code and transmits a frequency signal corresponding to the discrimination code periodically with a communication frequency in a specific band having a fixed range communication distance. And a receiver(400) is connected to the transmitter wirelessly, and sets a communication channel with the transmitter according to operation state of a switching device, and receives the frequency signal transmitted from the transmitter after applying a data input signal and then converts it into code data corresponding to the frequency signal and stores it in a memory, and converts the frequency signal transmitted from the transmitter thereafter into code data and compares it with the code data stored in the memory, and generates an alarm when the received code data does not coincide with the previously stored code data or the code data is not received from the transmitter.
    • 目的:提供一种用于损失和抢劫的射频收发器装置,通过输出警报来防止丢失和抢劫重要的事件。 构成:根据使用特定频带的通信频率进行RF通信的射频收发装置,以特定的识别码给出发射机(100,200,300),并以特定的通信频率周期性地发送对应于鉴别码的频率信号 频带具有固定的距离通信距离。 并且接收机(400)以无线方式连接到发射机,并且根据交换设备的操作状态设置与发射机的通信信道,并且在应用数据输入信号之后接收从发射机发射的频率信号,然后将其转换成 对应于频率信号的代码数据并将其存储在存储器中,然后将从发送器发送的频率信号转换为代码数据并将其与存储在存储器中的代码数据进行比较,并且当接收到的代码数据不 与先前存储的代码数据一致或者不从发送器接收代码数据。
