电信传输地震台网计算机系统中除计算机的通用设备外,还有一些地震传输台网专用设备,如地震触发器、编码遥控设备、SZ—3回放定位装置、SC—60型光线示波器等。这些设备必须通过接口电路与计算机联接。而这些接口电路是由台网用户自己设计,因此在设计和联接时必须注意计算接口的有关约定,不然不仅会影响专用设备的可靠性,还会影响整个计算机系统的可靠性。本文就是以地震专用设备与电子计算机系统进行联接时应解决的问题为例进行简要地讨论,也提出了一些具体方法,可供台网联调时参考。
Telecommunication transmission Seismic network computer system in addition to the computer’s common equipment, there are some special seismic transmission network equipment, such as seismic triggers, coding remote control equipment, SZ-3 playback positioning device, SC-60-type light oscilloscope. These devices must interface with the computer via interface circuits. However, these interface circuits are designed by the users of the network. Therefore, the design of the interface must be paid attention to when designing and connecting. Otherwise, not only the reliability of the dedicated device but also the reliability of the entire computer system will be affected. This article is a case study of the problems to be solved when the earthquake-specific equipment is connected with the electronic computer system as an example. It also presents some specific methods for reference when the network is connected.
