| 摘要: |
| 电脑钥匙是微机防误闭锁系统中的一个重要环节。提出了一种基于T89C51RC2为核心的非总线系统，并阐述了在此基础上，另加继电器等外围器件实现电脑钥匙的各项功能。该设计克服了总线形式下走线繁琐的缺点，有利于电脑钥匙小型便携化设计，提高了电脑钥匙的技干扰能力和工作可靠性。 |

| Abstract: |
| Computer key is very important in the interlock system for misoperation prevent ion.A non-bus system is proposed,which is based on T89C51RC2.The functions of computer key are realized with the system and some peripherals,such as relay.The design simplifies the wiring and makes the computer key smaller and portable.At the same time ,its anti-jamming ability and relia-bility are improved. |
| Key words: misoperation prevent ion,non-bus system,computer key |
