The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Practical implementation of the present invention is for example shown in the accompanying drawing; That shown in Figure 1 is the basic principle figure of optical detection yarn; Yarn to be detected moves in the zone between light transmitter (LED external light source) and light receiver (photoelectric sensor), and the variation of yarn diameter just can be decided by the change of the luminous flux that is received on the light receiver like this.Shown in Figure 2 is the structural representation block diagram of yarn testing circuit, mainly is made up of first power module 1, second source module 2, control module 3, RS485 communication module 4, signal detection module 5, external light source module 6,7 of alarm indication operational modules.
