[0002] With the development of hydropower station technology, the automation and intelligence of dam mechanical equipment such as gate machine, locking beam and orifice cover plate are increasingly required. However, at present, most of these devices still adopt independent operation mode, each for itself, lack effective data interaction and application, and cannot form a centralized and unified efficient collaborative operation system. This not only reduces the overall work efficiency, but also increases the operation complexity and maintenance difficulty.

[0003] The gate hoist used in hydropower station usually has the characteristics of large lifting load, small span, low running speed and large lifting range. Compared with the gantry crane (general gate machine) in general industrial occasions, the dam top gate machine of hydropower station needs to bear larger lifting capacity and its own weight, so the design must consider the influence of larger inertia force and heavy load, which puts higher requirements on the positioning accuracy of the gate machine.

[0004] In the existing operation process of hydropower station gate machine, the position of the gate machine is usually determined by the communication between the gate machine operator and the ground commander, and the deceleration and stop instructions are issued accordingly. However, due to the limitation of communication means, especially in noisy and poor visibility environment, this method leads to uncontrollability of gate machine positioning accuracy and low positioning efficiency. In addition, this traditional positioning method relying on manpower not only increases the work burden and potential safety hazards of the operator, but also indirectly increases the operating cost of the hydropower station; in addition, the hydropower station gate is usually stored in a remote area, which is time-consuming and laborious to transport by crane and lacks unified planning and management.
