    • A system for managing sales of goods for vending machines includes a goods control center, a plurality of vending machines, and terminal computers equipped in the respective vending machines. The goods control center includes a host computer for preparing digital data signals as control instructions, and a frequency moderation sub-carrier broadcasting facility as a transmission facility for outputting the digital data signals. Each vending machine has a receiving facility for receiving the digital data signals from the goods control center, and a responding facility. Each terminal computer receives the digital data signals and selectively extracts the digital data as the control instructions necessary for the vending machine to thereby store the digital data necessary for the vending machine in a memory. Each terminal computer controls the vending machine on a basis of the control instructions stored in the memory, obtains goods market information of the vending machine, and outputs the goods market information to the responding facility for reporting the information to the host computer at the goods control center.
    • 用于管理自动售货机的商品销售的系统包括货物控制中心,多台售货机以及配备在各自的售货机中的终端电脑。 货物控制中心包括用作准备作为控制指令的数字数据信号的主计算机,以及作为用于输出数字数据信号的传输设备的频率调节子载波广播设施。 每个售货机具有用于从商品控制中心接收数字数据信号的接收设备和响应设备。 每个终端计算机接收数字数据信号,并且选择性地提取数字数据作为自动售货机所需的控制指令,从而将自动售货机所需的数字数据存储在存储器中。 每个终端计算机根据存储在存储器中的控制指令来控制自动售货机,获得自动售货机的商品市场信息,并将货物市场信息输出到响应设施,以在货物控制下向主机报告信息 中央。
