基于西门子PLC 的河道治理系统设计

Design of River Training System Based on Siemens PLC

农业灌溉源湖泊,湖泊水质易受到农业面源污染,一方面需要对湖泊入水口处的垃圾进行打捞,另一方面需对各排入湖泊的污水进行进化达标后,方可排入湖中。针对湖泊入水口处的垃圾自动打捞部分,提出一种基于PLC的河道治理系统,提供本地手动和本地自动以及远程后台自动控制三种方式,后台根据本地摄像头回传的河道信息,判断是否启动垃圾打捞系统,另外后台根据气象信息针对河道入湖口及时升降打捞机,做好打捞准备和泄洪防汛。

The water quality of agricultural irrigation source lakes is vulnerable to agricultural non-point source pollution.On the one hand,the garbage at the lake inlet needs to be salvaged,and on the other hand,the sewage discharged into the lakes needs t o be e volved to meet the s tandards before it c an be dischar ged into the lak es.For the g arbage automatic salvage part at the lak e inlet,a PL C based river tr aining system is pr oposed,which pr ovides three modes:loc al manual and automatic control and remote background automatic control.The background determines whether to start the garbage salvage system according to the river channel inf ormation returned from the loc al camera.In addition,the b ackground lifts the salvage machine in time ac cording to the me teorological information at the river inle t to prepare for salvage and flood control.
