Abstract

The present invention provides a GPC controller remote control device and its control method. The device can realize the control of unit startup, shutdown, closing and opening, including GPC controller UP01, relay KA01, relay KA02, double-headed button switch SB11 , a double-head push button switch SB12 and a DC power supply; the relay KA01 is a four-pole relay, and the relay KA02 is a two-pole relay or a four-pole relay; the double-head push button switch SB11 includes an upper normally open contact SB11‑U and a lower normally open contact The closed contact SB11‑D, the double-headed push button switch SB12 includes an upper normally open contact SB12‑U and a lower normally closed contact SB12‑D. The present invention uses a relay+GPC controller to replace the original PLC+GPC controller to realize the control of unit startup, shutdown, closing and opening, which simplifies the operation process, improves the visibility of the operation, and has high economical device selection .

Description

technical field [0001] The invention relates to the technical field of GPC controller remote control, in particular to a GPC controller remote control device and a control method thereof. Background technique [0002] The two-point control relationship of GPC control is as follows: in the standby state of the unit, both terminals 25 and 43 have high potential, and GPC executes start; when terminal 25 has high potential, and terminal 43 has no high potential, GPC executes closing; , both terminals 25 and 43 have high potential, and GPC performs opening; if terminal 25 has no high potential, GPC executes shutdown. [0003] The traditional control system is controlled by PLC+GPC. The button switch on the operation control panel inputs the high potential to the input module of the PLC, which is programmed and confirmed by the PLC, and the high potential is output to the 25 terminal of the GPC controller through the PLC output module and 43 wiring, GPC correspondingly executes t...
