    • A system for detection of tampering with a utility meter provides not only an indication that tampering has occurred but also sufficient information to enable an estimation of actual consumption to be made as opposed to the tampered metered consumption. The device includes a plurality of tampering sensors sensing tilt, electric field, magnetic field, temperature, sound, reverse rotation of a moving element and excessive difference between metered consumption and an approximate actual consumption. The device also measures the movement of the moving element. These sensed signals are recorded in sequential time periods of for example eight hours so that an analysis can be made on a daily basis to provide an accurate pattern of consumption as opposed to the tampered meter consumption pattern.
    • 用于检测公用电表的篡改的系统不仅提供了篡改已经发生的指示,而且还提供了与篡改的计量消耗相反的估计实际消耗的足够信息。 该装置包括检测倾斜,电场,磁场,温度,声音,移动元件的反向旋转的多个篡改传感器以及计量消耗与近似实际消耗之间的过大差异。 该装置还测量移动元件的运动。 这些感测信号在例如8小时的连续时间段中记录,使得每天可进行分析以提供与篡改的仪表消耗模式相反的精确消费模式。

    • A method for communicating data between a central data terminal, a plurality of intermediate data terminals, a plurality of remote cell nodes, and a plurality of network service modules, using a plurality of frames with each frame having a plurality of channels. The plurality of intermediate data terminals transmit IDT-synchronization signals to the plurality of remote cell nodes on a first channel of the frame. The plurality of remote cell nodes transmit RCN-synchronization signals to the plurality of network service modules on a second channel of the frame. The network service modules transmit data from a plurality of physical devices, using radio waves, as NSM-packet signals to the plurality of remote cell nodes using a fourth channel of the frame. The plurality of remote cell nodes store the incoming NSM-packet signals and, responsive to a first polling signal transmitted in a third channel of the frame from a particular intermediate data terminal, transmit the NSM-packet signals to the intermediate data terminal as RCN-packet signals on a fifth channel of the frame. The intermediate data terminal in turn stores the RCN-packet signals received from the plurality of remote cell nodes and, responsive to a second polling signal transmitted from the central data terminal on a sixth channel of the frame, transmits the RCN-packet signals as an IDT-packet signal on a seventh channel of the frame to the central data terminal.
    • 一种用于在每个帧具有多个信道的多个帧之间在中央数据终端,多个中间数据终端,多个远程小区节点和多个网络服务模块之间传送数据的方法。 多个中间数据终端在帧的第一信道上向多个远程小区节点发送IDT同步信号。 多个远程小区节点在帧的第二个信道上向多个网络服务模块发送RCN同步信号。 网络服务模块使用无线电波将来自多个物理设备的数据作为NSM分组信号使用帧的第四通道向多个远程小区节点发送数据。 多个远程小区节点存储进入的NSM分组信号,并且响应于在特定中间数据终端的帧的第三信道中发送的第一轮询信号,将NSM分组信号作为RCN- 分组信号在帧的第五通道上。 中间数据终端又存储从多个远程小区节点接收到的RCN分组信号,并且响应于在帧的第六信道上从中央数据终端发送的第二轮询信号,将RCN分组信号作为 IDT分组信号在帧的第七个信道上到中央数据终端。
