However, the giant die forging hydraulic press has the characteristics of huge structure, harsh on-site environment, serious interference, long stroke of moving parts, severe shock and vibration, long signal transmission line, and many restrictions on the wiring of the control system. Conventional detection methods and means are difficult to adapt to. Its special working environment, therefore, in order to realize the non-working direction offset detection function of the movable beam in the special environment of the giant forging hydraulic press, it is necessary to develop a high reliability and high flexibility detection of the non-working direction offset of the movable beam of the hydraulic press system

The invention provides a method for detecting the deflection of a movable beam of a large forging hydraulic press in non-work direction and a device thereof. Two high-speed CCD image sensors are utilized to shoot detecting markers on vertical angles of a movable beam of the large forging hydraulic press, and image processing algorithm is used for dealing digital images to figure out the two-dimensional deflection values of the two vertical angles of the movable beam of the large forging hydraulic press according to the real time shot image of the detecting markers and the image of the detecting markers when the detecting markers are at the beam reference positions by an embodied image dealing module. The two-dimensional deflection values of the center of the movable beam and the angle defection value of the movable beam can be obtained, and finally, the status inspection of the movable beam in the non-work direction can be realized by a PLC controller and a leading computer system. The invention greatly increases the product processing quality and the use safety, reliability, and use and maintenance effect of equipment, and prolongs the service life of the large forging hydraulic press by effective real time detection on the deflection of the movable beam of the hydraulic press.
