为推广和发展计算机在播控系统的自动管理,国内已有不少微机控制的录音机自动播出装置,但还都停留在准自动的水平。这是因为目前开盘式录音机的磁带装卸、倒换还仍然必须靠人工,除非使用机械手,很难做到完全自动,因而不能保证广告节目和补充音乐的有效播出。为此我们研制了一种多卡全自动放音机,其操作和接口方式均很简单,只占用一台放音机的接口地址。 In order to popularize and develop the automatic management of the computer in the broadcast control system, there are many automatic recording devices controlled by computer in our country, but all of them still stay in the quasi-automatic level. This is because at present tape recorders tape loading and unloading, the exchange must still rely on manual, unless the use of manipulators, it is difficult to be completely automatic, and therefore can not guarantee the effective broadcast advertising programs and supplementary music. To this end we have developed a multi-card automatic player, the operation and interface methods are very simple, only take up a radio interface address.
