目前LNG槽车充装多为手动充装,过程步骤多、推动臂费力、阀门开闭操作繁琐,造成操作员工作强度大、精神紧张易疲劳,容易引发槽车充装过量,进而导致安全阀起跳等安全事故。为改进LNG槽车生产运营方式,降本增效,实现精细管理,开发了LNG槽车智能化充装系统,包括槽车装车橇、与槽车的快速接口、槽车仪表升级改造和槽车车辆管理流程控制系统,使槽车充装过程操作方便、监测自动化、加注过程控制智能化,有效降低操作员工作强度,提高槽车充装全过程整体安全性。新开发的LNG槽车智能化充装系统可为开展全自动机械手装车橇的研究提供基础,最终实现槽车区充装可视化、无人化,为新型智能槽车和未来罐箱批量充装做技术储备。

At present, LNG road tankers are mostly loaded manually, and the loading process is complicated, involving many procedural steps and valving sequences, and very demanding on operators physical strength in moving the loading arms. As a result, the intense work load of this operation brings both physical and mental fatigue to the operators, and that can easily result in over filling of the road tanker and cause the lifting of the safety relief valve. To improve the production operation mode involving LNG road tanker, reduce cost and increase efficiency, and achieve delicacy management; smart LNG road tanker loading system is developed. This smart system includes road tanker loading skid, quick coupling for connection with the road tanker, upgrade of tanker instrumentation and road tanker management procedure control system. With this new system, the loading process of LNG road tanker is easily operated, automatically monitored, and controlled via artificial intelligence. Thus, the operators’ manual work intensity is reduced, and the safety of the LNG truck loading process is enhanced. This new system can provide a basis for the research of fully automatic loading arm for tanker loading skid, and finally achieve the remote operation with visual monitoring of the unmanned road tanker loading area, and can also serve as a technical resource for research in the field of new smart road tankers and the future batch tank loading operations.
