PLC控制系统中的干扰是一个十分复杂的问题，因此在抗干扰设计中应综合考虑各方面的因素，合理有效地抑制抗干扰，才能够使PLC控制系统正常工作。随着PLC应用领域的不断拓宽，如何高效可靠的使用PLC也成为其发展的重要因素。21世纪，PLC会有更大的发展，产品的品种会更丰富、规格更齐全，通过完美的人机界面、完备的通信设备会更好地适应各种工业控制场合的需求，PLC作为自动化控制网络和国际通用网络的重要组成部分，将在工业控制领域发挥越来越大的作用 原有系统装在20多台门机（门吊）上，目前已经安装了称重数据采集系统（单片机开发），采用IC卡式数据传输方式，由于软件构件缺乏科学性和合理性而且数据采集错误的情况比较严重，导致管理软件并未起到应有的作用。原有系统数据传输的时滞性和准确性都需要改进，上位机管理软件也需要进行相应的更新，以达到真正的门机作业自动化管理。为了实现科学的、方便的管理，现在需要将门机称重系统、风速仪以及门机工作状态信息数据一同实时传到门机队监控中心，解决IC卡式数据传输方式的时滞，加强对门机工作的管理力度和工作过程中的事故防范能力，系统采用GPRS的无线数据传输方式，确保现场和管理中心所得到的数据的一致性，在工作现场配备RTU-2600智能终端，以便于实时采集、传输数据；配备HMI-3800人机界面供门机司机进行操作；在管理中心重新配备上位机数据管理软件，接收现场工作数据，并实现用户管理、曲线显示、报表打印、历史数据记录等功能。
