Encoder signal simulation system and method applied to simulator of loading and unloading machine

Abstract

The invention discloses an encoder signal simulation system and method applied to a simulator of a loading and unloading machine. The method includes: firstly calculating a current numerical value of the encoder according to collected speed and moving direction signals sent by a large vehicle, a small vehicle or a main lifting handle of a console of the loading and unloading machine; secondly converting the current numerical value and obtaining an encoder SSI (synchronous serial interface) simulation signal corresponding to an actual encoder value according to a real encoder hardware; and lastly, obtaining a transmission time series of the encoder SSI simulation signal according to a synchronous SSI clock signal sent by an encoder SSI simulation signal receiving device, and sending the encoder SSI simulation signal to the encoder SSI signal receiving device to finish the analogue simulation of the encoder SSI simulation signal. The simulator system and method can flexibly control the encoder simulation signal of the simulator of the loading and unloading machine and simulates different working conditions without relying on the real encoder hardware device, thereby improving the training efficiency of an operator of the loading and unloading machine of a nuclear power station.

Description

Technical field [0001] The invention relates to the field of analog simulation control of a loading and unloading machine in a nuclear power plant, in particular to an encoder signal simulation system and a simulation method applied to a loading and unloading machine simulator. Background technique [0002] The loading and unloading machine is the key equipment to complete the refueling of the reactor during the shutdown and refueling of the nuclear power plant. The fuel assembly is loaded, unloaded and transferred underwater between the reactor core and the fuel transfer device tipper (RX side). Its service area is the reactor refueling The pool and the storage pool for internals of the heap. Judging from the experience in the use of loading and unloading machines in nuclear power plants at home and abroad, during the operation of nuclear power plant units, the loading and unloading machines are parked in the reactor building, and the loading and unloading machines cannot be use...
