Embodiment
[0033] This embodiment is an auxiliary alignment system for a dam crest gate machine, which is applied to a hydropower station with six gates. Auxiliary alignment system of dam crest door machine such as figure 1 As shown, it includes a human-computer interaction unit 1, a control unit 2, and a sensing positioning unit 3. The sensing positioning unit includes a distance detection device 4 for detecting the moving distance of the door machine, a target plate 5 set near the gate, and a target plate set on the door. The induction switch 6 for sensing the target board on the machine, the human-computer interaction unit, the induction switch and the distance measuring device all communicate with the control unit, and the control unit communicates with the original operating system 7 of the door operator. The human-computer interaction unit includes a touch screen 30 and a camera 31 for acquiring the movement of the door operator. The touch screen is connected to the control unit, a...

The invention discloses a dam crest gantry crane auxiliary alignment system and a dam crest gantry crane auxiliary alignment method. The dam crest gantry crane auxiliary alignment system comprises a man-machine interaction unit, a control unit and a sensing positioning unit, wherein the sensing positioning unit comprises a distance detection device, a target plate and an inductive switch, the man-machine interaction unit, the inductive switch and the distance detection device communicate with the control unit, and the control unit communicates with an original operation system of a gantry crane. The dam crest gantry crane auxiliary alignment method comprises the steps of: S1, arranging an induction rod; S2, selecting a gate number; S3, detecting a moving distance of the gantry crane by means of an encoder when the gantry crane moves; S4, when a left side speed reduction switch / right side speed reduction switch senses the target plate, displaying speed reduction information on a touch screen; S5, when a stop switch senses the target plate, displaying stop information on the touch screen; S6, and judging whether the current position of the gantry crane is a specified gate or not by using a position detection switch, if so, indicating that alignment is completed, if not, calculating the distance between the current position and the specified gate and initializing the encoder, andreturning to the step S3. The dam crest gantry crane auxiliary alignment system and the dam crest gantry crane auxiliary alignment method have the advantages of being good in safety and expansibility,precise in portal crane alignment and high in system reliability.
Description
technical field [0001] The invention relates to the field of door machine control, in particular to a dam crest door machine auxiliary alignment system and method. Background technique [0002] In a traditional hydropower station, the movement of the door crane, access to the maintenance door, and entry into the tank are all manually operated and confirmed step by step. For example, the door operator needs to point to the position of the door slot, which is completely controlled manually by the operator in the high-altitude control tower, and then cooperates with the ground personnel to repeatedly confirm the position. The whole process is completely manual operation, which has the problems of large errors, many personnel involved, and very low work efficiency. [0003] Therefore, under the condition of fully ensuring the safety of the current system, a set of auxiliary door drop device system is added to improve the current operating system of the door operator. Not only ...
