Refueling machine control system and control method for nuclear power plant

Abstract

The invention belongs to the technical field of refueling machine control, and particularly relates to a refueling machine control system and a refueling machine control method for a nuclear power plant. In the refueling machine control system, a No. 2 computer host and a No. 1 computer host are connected with a communication network; the No. 1 computer host, the communication network, a process control unit and an input-output unit are sequentially connected; and the communication network is connected with an engineer station computer reserved communication interface, a control unit A and a control unit B. The refueling machine control method comprises the steps of: step 1, selecting a starting position and a target position by an operator, and establishing a process cycle; step 2, generating a corresponding process cycle plan according to the process cycle in the step 1; step 3, generating a macro operation project according to the process cycle plan generated in the step 2; step 4,generating a micro operation project according to the macro operation project; step 5, and executing the micro operation project by means of the refueling machine. The refueling machine control systemand the refueling machine control method improve the working efficiency of the refueling machine and shorten the material loading and unloading time on the basis of ensuring nuclear safety.

Description

technical field [0001] The invention belongs to the technical field of refueling machine control, and in particular relates to a control system and a control method for a refueling machine used in a nuclear power plant. Background technique [0002] By summarizing the operating experience of the refueling machine, the loading and unloading process can be further optimized, such as the position of the camera rod passing through the transportation corridor, the fuel assembly gripper or fuel assembly transportation position in the same area, and the movement logic algorithm of each mechanism And the unreasonable layout of control equipment, etc., combined with the actual situation that FA-2M components will be used for long-term refueling, can increase and set different loading and unloading speeds in different surrounding environments of fuel components, so as to save time on the main line. [0003] On the basis of the existing system, in order to achieve the goal of increasin...
