1.安装(1)合理布线布线要依据图纸和电气元件的安装位置由外围向各控制单元或控制室一一集中;要选择合适的路径,弱电和强电信号电缆要分槽布置;为了保证电信号有效可靠地传输,电气线路的连接必须可靠、紧固;必须有足够的接地极,并相互连接成网,以防漏电和雷击;沥青站的各主要控制单元一般都采用工控机和PLC (可编程逻辑控制器),其控制过程都要求内部电路检测到满足一定逻辑关系的电输入信号后,及时输出符合一定逻辑关系的电信号去驱动继电器或其他电气单
1.Installation (1) Reasonable wiring and wiring should be centralized from the periphery to each control unit or control room according to the drawing and the installation position of the electrical components; to select the appropriate path, the weak and strong electrical signal cables should be arranged in slots; in order to ensure Electrical signal transmission is effective and reliable, the connection of electrical lines must be reliable and secure; there must be enough grounding poles, and interconnected into a network to prevent leakage and lightning strikes; the main control unit of the asphalt station are generally used IPC and PLC (Programmable logic controller), the control process requires the internal circuit detects the electrical input signal to meet a certain logic, the timely output of a certain logical relationship between the electrical signals to drive the relay or other electrical single
