Inspection method and information processing device for pneumatic conduit equipment

Abstract

To detect a defect of a pneumatic tube and to easily calculates the position of the defect.SOLUTION: The present invention relates to an information processor 100 which is used to inspect a pneumatic tube system 1 which moves a pneumatic element 5 in a pneumatic tube 4, and the information processor comprises: an input part 101 which inputs moving image data that a camera 6 records and sound data that the camera 6 records, the data being acquired by moving the pneumatic element 5, having the camera 6 built in, inside the pneumatic tube 4, and the camera serving as imaging means for capturing images in time series and sound collection means for collecting a sound in time series; a detection part 102 which detects a defect of the pneumatic tube 4 based upon the image data input by the input part 101; and a calculation part 103 which calculates the position of the defect detected by the detection part 102 based upon the sound data input by the input part 101.SELECTED DRAWING: Figure 3

Claims

1. A method for inspecting pneumatic conduit equipment, which involves inspecting pneumatic conduit equipment that moves a pneumatic carrier within a pneumatic conduit, A movement procedure for moving the air carrier, which incorporates an imaging means for acquiring time-series images and a sound collection means for collecting time-series sounds, within the air supply tube, A detection procedure for detecting defects in the pneumatic tube based on the image acquired by the imaging means, A method for inspecting a pneumatic conduit system, comprising: detecting the departure sound and arrival sound of the pneumatic carrier from the sound collected by the sound collection means; and a calculation procedure for calculating the location of the defect detected in the detection procedure based on the departure sound and arrival sound.

2. In the above calculation procedure, Based on the aforementioned departure sound and arrival sound, the travel time from the departure to the arrival of the air carrier is calculated. Based on the aforementioned travel time and the length of the pneumatic tube, the average velocity of the pneumatic carrier is calculated.
