Problems solved by technology

[0007] At present, in countries with a high level of swimming, this type of water traction training system is manually controlled: the adjustment of the speed is intermittent, and it cannot be set in advance, let alone memorized and displayed; its start and stop control is also carried out manually , can not realize the automatic segmental continuous control of the speed

Embodiment Construction

[0037] The program flow chart of programmable controller in the control method of water traction training that the present invention proposes is shown in figure 2 and image 3 . Among them, m+ is the number of times the button is pressed during manual acceleration control; m- is the number of times the button is pressed during manual deceleration control. Its control is a swimlane.

[0038] exist Figure 4 Among them, 7 and 8 are left and right brackets respectively, 9 is a variable frequency motor, 10 is a rotary encoder, 11 is a control cabinet, 12 is a manual control box, 13 and 14 are two left and right photoelectric sensors respectively, and 15 is a random Moving baffle, 16 is auxiliary rope, and 17 is swimming pool.

[0039] Figure 5 Included each control unit relevant to the present invention in the dashed frame, they are respectively: the model that programmable logic controller (PLC) adopts is the FPO-C32CT that Japanese Panasonic Company produces; The expansi...

Abstract

A method for controlling the drag training on water surface features that the frequency-variable motor can be automatically and segmentally controlled by a programmable controller or a in-situ touch screen, and the control parameters can be manually modified and real-time displayed. A programmable control system is composed of programmable controller, manual control box, intelligent touch screen,A / D converter, frequency variator, frequency-variable motor, rotary encoder, photoelectric sensors and following barrier.

Description

technical field [0001] A control method for traction training on water and a programmable control system thereof belong to the technical field of sports auxiliary training. Background technique [0002] The water traction training system is a kind of equipment that assists swimmers to train in the water. It crosses two steel cables on both sides of the swimming pool through the traction support frame, and hangs a traction rope below the waist of the swimmer, through the motor drive system. , drives the traction rope to go back and forth between the two sides of the swimming pool at a variable speed. The system works as figure 1 shown. 1 is a transmission system; 2 is a manual control device; 3 is a motor; 4 is a traction rope for pulling athletes; 5 is a traction steel cable; 6 is an athlete. [0003] Because it can change the speed of pulling athletes in the water, it can achieve the following three purposes in swimming training: [0004] 1. It can make athletes move at...
