Fig. 1 is the structured flowchart of the utility model embodiment;
Fig. 2 is the structural drawing of the utility model embodiment;
In figure, 1. nozzle; 2. slide calliper rule; 3 controllers; 4 checkout equipments.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, embodiment of the present utility model is as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and principle of work, manufacturing process and operation using method etc., be described in further detail, with help those skilled in the art to utility model of the present utility model conceive, technical scheme has more complete, accurate and deep understanding.
The object that utility model realizes, is mainly to utilize code-spraying equipment on cable, to get a series of point, and the mistiming of utilizing fetch equipment to read adjacent point is calculated the translational speed of cable, calculates the length of cable with time velocity coordinate system.Code-spraying equipment is provided with two nozzles 1, and nozzle 1 is fixed on support, and the distance of two nozzles 1 is certain, and nozzle 1 is controlled by the controller 3 of code-spraying equipment, and while getting ready, two nozzles 1 are got ready simultaneously at every turn, and the distance between guaranteeing at 2 is certain.When coding fetch equipment reads two points, record respectively the time, according to the distance of mistiming and nozzle 1, obtain the average velocity between these 2, cable.Code-spraying equipment is laid and is organized a little more on cable, and fetch equipment just can record the translational speed of a series of cables, utilizes mapping software in coordinate axis, to describe time rate curve, and the area between curve and time coordinate axle is cable length.
As Fig. 1, on code-spraying equipment, be fixed with two nozzles 1, nozzle 1 can be along base sliding, and base is provided with slide calliper rule 2, for regulating the distance of two nozzles 1.When system requirements precision is higher, make the distance of two nozzles 1 less.The time interval that nozzle 1 is got ready is controlled by the controller 3 of code-spraying equipment, and when checkout equipment 4 detects cable speed when higher, by data feedback, to code-spraying equipment controller 3, controller 3 is controlled injection frequencies and uprised, and makes to get ready intensive.
In order to reduce cost, the pigment of nozzle 1 ejection is selected common pigments, but not reflexible fluorescent material etc.Pigment adopts white, strengthens aberration.In coding checkout equipment 4, be provided with picture recognition module.First, image acquisition equipment obtains consecutive image, then utilizes histogram equalization method, strengthens the contrast of image, makes punctuate in image be more prone to differentiate.Checkout equipment 4 detects punctuate and records the time instantly, records another time when on the same group another being detected again, just can calculate cable at the average velocity of this segment distance according to the mistiming.Because twice image recognition all can cause time lag, therefore can not affect the error of calculation.
Checkout equipment 4 is sent testing result into code-spraying equipment, and as the decision-making foundation of code-spraying equipment, cable speed changes and increases coding frequency when fast; When cable speed changes not quite comparatively steadily, reduce coding frequency.
According to cable travelling speed and the time point of checkout equipment 4 records, under coordinate, draw time rate curve, the area between curve and time shaft is the length of cable.Utilize function curve of computer fitting, area between calculated curve and time shaft just can draw cable length, computing machine is ripe at fitting function curve, reference area this part, and the utility model is in system architecture, rather than the improvement made of computer software this part.
In order to make result more accurate, increase several groups of coding checkout equipments 4, this testing result of several groups does not feed back to code-spraying equipment, and numerical value during last result of calculation, several groups of equipment being obtained is averaged or intermediate value.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
