Problems solved by technology
[0003] The model of the unit is getting bigger and bigger, the height of the tower is getting higher and higher, and elevators and other equipment are installed inside to provide up and down equipment. The existing elevator equipment and the control system of the wind turbine unit are independent systems, and there is no safety interlock protection , when the maintenance personnel are negligent or in order to quickly deal with the fault, the unit is switched to the local control mode, and at this time the on-duty personnel mistakenly start the machine remotely, and the maintenance personnel are in the elevator or entering the engine room to start the unit, which is very dangerous. Hidden dangers, for this reason we propose a unit safe operation locking system to solve the above problems

The invention discloses a unit safe operation locking method which comprises the following steps: acquiring internal fault information of a unit, and reporting fault information parameters; the maintainer obtains a corresponding maintenance task and controls the lifting equipment to a designated position; establishing a three-dimensional space model in the unit, implementing digital management, monitoring personnel positions, and performing scene simulation; after the lifting equipment leaves the platform, the limiting switch acts, and a position signal of the local / remote control loop connected to the limiting switch is obtained; according to the invention, through remote three-dimensional space simulation, personnel in a control room can timely and clearly know the internal condition of the unit, more accurate digital management is realized, the position of personnel in the unit is effectively detected, and meanwhile, through action signal conversion of the limit switch, the control terminal can timely receive signal data and make more accurate judgment, so that the working efficiency is improved. The safety of workers in the unit is effectively improved, and the intelligence of unit maintenance operation is further improved.
Description
technical field [0001] The invention relates to the technical field of safe operation of units, in particular to a locking system for safe operation of units. Background technique [0002] The wind turbine consists of a wind wheel and a generator; the wind wheel contains blades, hubs, reinforcements, etc. The wind power source is composed of the wind generator set, the tower supporting the generator set, the battery charging controller, the inverter, the unloader, the grid-connected controller, and the battery pack. The frequency is constant. This is necessary for both wind turbine grid-connected power generation and wind-solar hybrid power generation. [0003] The model of the unit is getting bigger and bigger, the height of the tower is getting higher and higher, and the elevator and other equipment are installed inside to provide up and down equipment. The existing elevator equipment and the wind turbine control system are independent systems, and there is no safety int...
