摘要： An electronic electricity meter which, in one embodiment, includes a modem board, or unit, coupled to the meter microcomputer (20) and exchanges information between the meter (10) and a central computer (58) is described. Using signals supplied by the meter microcomputer (20) and the central computer (58), the modem unit (50) microcomputer can determine whether to exchange information between the meter and the central computer (58) and the proper time at which the information should be exchanged. In an exemplary embodiment, the modem unit (50) detects various conditions within the meter and responds by exchanging information with the central computer (58) at a proper, or pre-defined, time. The modem unit has two different basic modes, or states, of operation. These states of operation are sometimes referred to as the call originate mode and the call answer mode. Call originate refers to the mode of the unit when a condition occurs in meter 10 and information is being transmitted to the central computer (58) from the modem unit (50) utilizing a telephone line. The call is originated upon occurrence, for example of a power outage to the meter. In the call answer mode, the central computer originates a call to the meter. The central computer (58) can then transfer information to the meter, for example a new program can be stored in the modem unit memory.
摘要翻译：描述了在一个实施例中包括耦合到仪表微计算机（20）并且在仪表（10）和中央计算机（58）之间交换信息的调制解调器板或单元的电子电表。调制解调器单元（50）微计算机利用由计量器微计算机（20）和中央计算机（58）提供的信号，可以确定是否在计量器和中央计算机（58）之间交换信息，以及信息应该交换。在示例性实施例中，调制解调器单元（50）检测仪表内的各种状况，并通过在适当的或预定义的时间与中央计算机（58）交换信息来作出响应。调制解调器单元有两种不同的基本工作模式或状态。这些操作状态有时被称为呼叫发起模式和呼叫应答模式。呼叫始发是指当仪表10中出现状况并且利用电话线将信息从调制解调器单元（50）发送到中央计算机（58）时该单元的模式。呼叫是在发生时发起的，例如电表断电。在通话应答模式下，中央计算机向电表发出呼叫。中央计算机（58）然后可以将信息传送到仪表，例如可以将新程序存储在调制解调器单元存储器中。
