    • In a multi-mode dual channlel data link there is provided a method for automatically controlling or allocating a predetermined amount of power to each of the dual channels. Two diverse product signal are transmitted from a master station down link to a plurality of ground stations. The ground stations receive the diverse product signals and individually determine the integrity of each product signal and transmit the product integrity information and a station identifier back to the master station. The master station processes the integrity information and reallocates a predetermined percentage of total power to be transmitted from each of the dual channels to achieve a predetermined product integrity at one or more of the plurality of ground stations.
    • 在多模双通道数据链路中,提供了一种用于自动控制或分配预定量的功率给每个双通道的方法。 两个不同的产品信号从主站下行链路发送到多个地面站。 地面站接收各种产品信号,并单独确定每个产品信号的完整性,并将产品完整性信息和站标识符发送回主站。 主站处理完整性信息并且重新分配要从每个双通道发送的总功率的预定百分比,以在多个地面站中的一个或多个处获得预定的产品完整性。

    • A portable test receiver for field maintenance of a remote sensor monitoring system for underground transformers. The apparatus uses a phase locked loop method to demodulate the DPSK modulation of the remote monitor transmitter. The apparatus is battery operated and easily moved to permit monitoring of spot networks and critical locations for maintenance work. The apparatus features a single software driven display offering good visibility with low current drain. Decoding the transmitter signal is accomplished by using the crystal oscillator circuit of the transmitter is used to generate a reference which is compared to the transmitter signal to detect phase flips. Since the apparatus is battery-powered, there is no AC power to provide "zero" crossing points of the monitored transmitter. Bit timing is provided by taking advantage of the nulls at the 60 cycle "zero" crossings found in the transmitter signal.
    • 用于地下变压器远程传感器监控系统的现场维护的便携式测试接收器。 该装置使用锁相环方法来解调远程监视发射机的DPSK调制。 该装置是电池操作的并且容易移动以允许对现场网络和关键位置的监视进行维护工作。 该装置具有单个软件驱动显示器,具有低电流消耗的良好可见性。 发射机信号的解码是通过使用发射机的晶体振荡器电路来产生与发射机信号进行比较的参考,以检测相位翻转。 由于该设备是电池供电的,所以没有交流电源来提供被监测发射机的“零”交叉点。 通过利用在发射机信号中发现的60个周期“零”交叉处的空值来提供比特定时。
