煤四期扩容工程堆场位于现煤四期堆场南侧，布置3条堆场,堆场设备采用两台悬臂式堆料机、4台取料机和堆场皮带机进行装卸作业。煤堆底部宽度为56m，堆高17m，堆场长度1105m，堆料线和取料线的中心距为

［作者简介］孙鲁(1961－)，男，山东临沂人，工程师，研究方向，自动控制及应用。
制堆场198个喷枪的自动喷洒作业和转接机房、码头等区域供水设备的信号采集及设备控制。洒水除尘控制系统采用一台Rockwell公司的Controllogix 系列PLC，与两台上位监控操作站通过以太网相连。控制点数约3000点左右。上位监控操作站和PLC设于洒水泵房控制室。
2 系统方案确定
由于本工程堆场洒水喷枪站及其它设备控制站153个，且数量多、分布广、距离远，现场作业环境恶劣，绝大多数为户外露天使用。如采用传统的PLC远程站方式控制，在每个喷枪站单设一个远程站，将会使成本大大提高，另外，PLC模块的防护等级较低,工作时温度范围一般为00C ～400C，难于适应恶劣的现场环境和秦皇岛冬季较低的气温(最低－200C)；如把PLC远程站设于堆场附近的变电所或洒水泵房控制室内，则将耗费大量的控制电缆、电缆桥架，并且极大的增加了敷设电缆及安装桥架的施工工程量和加大了日后控制电缆的维护工作量,根据设计和计算，仅从堆场附近的变电所引至堆场洒水喷枪站的控制电缆(kvv-14*2.5)就需约160km左右。
