TRS-80微型机是国内较早引进的计算机机种之一,它功能较强,可靠性好,普及率高。同时该微型机的硬、软件资料较全,应用在工业控制中比较方便。最近又公开出版了“TRS-80微计算机驻机解释程序”一书,因此在软件工作量大,尤其计算精度要求高,需要浮点运算的控制系统中采用该机,将大大减少软件工作量。但是,TRS-80微型机毕竟不是工业控制专用机,要用于工业控制,需要解决一些实际问题。下面谈谈我们利用TRS-80微型机组成“SOC-1型发酵罐计算机控制装置”时解决的几个实际问题。
TRS-80 microcomputer is one of the computer models introduced earlier in the country, it has strong functions, good reliability and high penetration rate. At the same time the micro-computer hardware and software information more fully applied in industrial control more convenient. Recently published “TRS-80 Microcomputer Home Interpretation Program,” a book, so the software workload, especially in the calculation of high precision, the need for floating-point control system using the aircraft, will greatly reduce the workload of the software . However, TRS-80 micro-machine, after all, is not a dedicated industrial control machine, to be used for industrial control, need to solve some practical problems. Now let’s talk about some practical problems that we solved when using the TRS-80 microcomputer to form a “SOC-1 fermentor computer control unit.”
