随着工业的自动化数字技术和集成组件生产技术突飞猛进的发展,工业遥控装置的应用也日益增多。然而由于冶金工业现场干扰较为严重、条件恶劣,加之遥控多用于远距离的控制,因而对遥控设备的稳定性、可靠性及抗干扰能力等要求自然高于其他设备。目前影响遥控装置使用的主要矛盾在于遥控装置的可靠性差、抗干扰能力低。遥控作为一种控制手段,已有几十年的历史了,控制方式也是多种多样的。目前由于数字技术和集成元件技术的迅速发
As industrial automation digital technology and integrated component manufacturing technology by leaps and bounds, the application of industrial remote control devices are also increasing. However, due to the more serious interference on the metallurgical industry site and the harsh conditions and the remote control used for long-distance control, the requirements on the stability, reliability and anti-interference ability of the remote control equipment are naturally higher than those of other equipment. At present, the main contradiction affecting the use of remote control devices lies in the poor reliability of remote control devices and low anti-interference ability. Remote control as a means of control, has decades of history, and control methods are varied. At present, due to the rapid development of digital technology and integrated component technology
