A real-time automatic counting method of production line output

Abstract

The invention discloses a production line output real-time automatic counting device and a counting method thereof. The device comprises laser range finding sensors and an industrial control computer. The laser range finding sensors are installed at one side of the roller way. The industrial control computer receives and analysis the signals of the laser range finding sensors. The automatic counting method comprises the steps that a laser ranging data curve map is acquired; a smooth curve map is acquired through image preprocessing; detection worms performs detection and steel bar roundness sequences are acquired through calculation; matching and comparison are performed on each segment of sequence so that the corresponding number of steel bars is acquired; and the total number of the steel bars is acquired via addition of the number of the steel bars corresponding to each segment of sequence. The beneficial effects are that the laser range finding sensors accurately receive information of workpieces on the roller way and the workpieces are accurately counted in real time through information analysis and calculation of the industrial control computer so that the device and the calculation process are low in error, high in statistics speed and low in maintenance cost; and screw-thread steel or steel pipes with great shape can be accurately counted, and partial warping screw-thread steel or steel pipes can also be accurately counted.

Description

technical field [0001] The invention relates to the technical field of electronic optical detection, in particular to an automatic real-time counting device and a counting method for product output on a production line of an iron and steel enterprise. Background technique [0002] For iron and steel production enterprises, especially steel pipe enterprises and rebar enterprises, real-time detection and statistics of their product output is an important task. The existing traditional detection methods include: manual counting method, automatic weighing method, computer vision image detection and counting method, etc. Among them, manual methods will produce counting errors due to long-term work fatigue and responsibility problems; automatic weighing and computer vision image detection methods, due to the sensor accuracy of the detection system itself and the complexity of image processing algorithms, more or less There is a certain measurement error, which brings a certain los...
