Embodiment 1

[0026] Such as figure 1 The shown a kind of non-contact laser scanning counting method based on statistical algorithm of the present invention comprises the following steps:

[0027] S1: Use an optical sensor to collect the grating signal when the product passes. In the present invention, the grating sensor is preferably used. The grating signal includes the start time and end time of the product passing, and the collected grating signal is added to the grating signal queue;

[0028] S2: Calculate the raster signal standard time and the raster signal average time interval of the raster signal queue, the raster signal standard time and the raster signal average time interval are the average value of the time data in the queue, and the grating signal standard time is the start of normal passage of a product The difference between the time and the end time, the average time interval of the grating signal is the time between two products, during normal production, the average tim...

Embodiment 2

[0038] by figure 2 and image 3 Take the claw pole 1 shown in as an example, the overall shape of the claw pole 1 is circular, and its diameter is 12cm. After collecting multiple sets of data and calculating, the standard time T1 of the grating signal of the claw pole 1 is 1.2 seconds, and the grating signal The average time interval T2 is 7.2 seconds, figure 2 The middle product is a normal and complete pass, and its grating signal time is 1.2 seconds, image 3 There are two claw poles 1, there is no gap between them, and the passing time is 1.75 seconds, which is greater than 1.25*1.2, so it is judged to be two claw poles 1.

Abstract

The invention relates to a non-contact laser scanning counting method based on a statistical algorithm. The method comprises steps that S1, a raster signal during pass of a product is acquired throughan optical sensor, and the acquired raster signal is added to a raster signal queue; S2, the standard raster signal time interval and the average raster signal time interval of the raster signal queue are calculated; and S3, the raster signal queue is grouped according to the standard raster signal time interval and the average raster signal time interval, and each group is processed to acquire acounting value. The method is advantaged in that counting is accurate and precise, under the condition of continuous conveyance of multiple products, counting missing is prevented, and multiple continuously pass-by products can be identified.

Description

technical field [0001] The invention relates to a non-contact laser scanning counting method based on a statistical algorithm, belonging to counting and statistical methods. Background technique [0002] With the development of society, the competition among industries is becoming increasingly fierce. In order to win the opportunities in the ever-changing environment, the management of enterprises have put forward higher requirements for internal production management. However, in the whole set of production management solutions, the statistics of the production capacity of each shift per day has become a difficult point, mainly for the following two reasons: In terms of machines, some production machines are not electrified enough to actively inform themselves of their production capacity ; In terms of products, some products have strange shapes, and after they leave the machine, there is a phenomenon that the positions are too dense; [0003] Take the situation of the cla...
