Control system and method for improving digging precision of dredging rope grab dredger
The invention relates to the technical field of dredging control of dredgers, in particular to a control system and method for improving the digging precision of a dredging rope grab dredger. According to the control method, the precise digging function is achieved through the tide level automatic compensation depth-keeping flat digging working condition. According to the fine digging, on the basis of a depth-keeping flat digging function, by collecting tide level numerical value information of a tide level remote reporting instrument, a tide level difference numerical value is automatically obtained and enters a central processor of a differ, the influence of the tide level on the digging depth is compensated, the digger is kept at the set digging depth elevation in real time, and the operation mode of manually correcting and compensating tide is removed; and depth-keeping flat digging precision is further improved, a fine digging function is achieved, digging depth precision is controlled within +/-20 cm, the blank of the equipment at home and abroad is filled, production cost is effectively reduced, and production efficiency is greatly improved.
本发明涉及挖泥船的挖泥控制技术领域，尤其涉及一种提高疏浚绳索抓斗挖泥船挖深精度的控制系统及方法，该方法通过潮位自动补偿定深平挖工况实现精挖功能。其中，所述的精挖是在定深平挖功能的基础上，通过采集潮位遥报仪的潮位数值信息，自动获取潮位差数值进入挖掘机中心处理器，补偿潮位对挖掘深度的影响，实时保持挖掘机作业在设定的挖深标高，去除了人工校正补偿潮汐的作业方式，进一步提高定深平挖精度，实现精挖功能，使挖深精度控制在±20cm以内，填补了此类装备国内外的空白，有效降低生产成本，大大提高生产效率。
