Abstract

The invention provides a cloth width measuring system. In the system, the connection and disconnection of a current circuit are formed by transmitting and receiving of a light emitting diode and a photodiode, and a corresponding signal is generated on a singlechip pin at a receiving section; and the an infrared photodiode is blocked when a cloth passes, so the partial or whole infrared photodiode on the receiving section cannot receive guiding light and cannot be connected, a controller at a receiving end collects a signal, and the transmitting controller and the receiving controller communicate with each other to judge and calculate the cloth width. The cloth width measuring system has the beneficial effects that the error value is between 1 and 2mm through accurate measurement to meet the detection standard of the cloth, and warning signals are generated when the system tests that holes are formed in the cloth and the length of the cloth is more than or less than the specified length, so that the problems of reduced finished product yield caused by greater measurement errors can be effectively solved.

Description

Cloth fabric width measuring system

(1) technical field

The present invention relates to a kind of measuring system of field of textiles, particularly relate to a kind of cloth fabric width measuring system.

(2) background technology

In the Weaving device operation process detects and in the process of product inspection, the width of cloth and length thereof need accurately strictly to set, and no this item measuring ability in the early stage equipment, only depend on the measurement of artificial visually examine or simple device, thereby the precision of measuring and the accuracy restriction that is subjected to artificial subjective experience, often cause holiday defective products in the process of patrolling and examining, finally cause unnecessary cost waste.

(3) summary of the invention

In order to overcome the deficiencies in the prior art part, the invention provides a kind of cloth fabric width measuring system.

Technical scheme of the present invention is to realize like this.

The technical scheme of native system is:

By light emitting diode and photodiode emission and the current return that receives formation conducting and disconnection, on the single-chip microcomputer pin of receiver section, produce corresponding signal, since cloth by the time can shelter from infraluminescence two utmost points, make part or whole infrared photodiode of receiving end can't receive the leaded light photograph to the greatest extent, thereby can't conducting, according to this principle receiving end controller acquired signal, then communicate at transmit control device and reception controller, and through accurately calculating the width of cloth after judging, again by 485 communication modules and 485 conversion RS-232 modules, realization is communicated by letter with host computer PC, can realize the control of host computer to Single Chip Microcomputer (SCM) system.

The technical essential of this programme also is:

(1), the width detection circuit part of cloth: send part PCB circuit, wherein the effect of transmit control device part is, the control infrarede emitting diode carries out multi-form lighting, can all light simultaneously, part is lighted, and circulation is lighted, and its master controller uses the 89s52 single-chip microcomputer; Produce electric current receive the illumination of emitting diode at the infrared photodiode of receiving end after, produce corresponding electric signal receiving end controller at the single-chip microcomputer pin of receiving end controller and also be to use the 89s52 single-chip microcomputer; The effect that receives controller is exactly to gather the electric signal that the previous step photodiode produces, and by calculating the quantity of the infrared photodiode that is sheltered from by cloth, because each infrared photodiode is equally spaced, just draw the width of cloth after as calculated.

(2), the communications portion of transmission and receiving end: be real-time, symmetry, the accuracy that guarantees to send and receive, partly add 485 communication circuit modules at the control circuit that sends and receive, the main control chip of module uses other 485 communication chip of 65LBC184 military project level, and guarantee not disturbed by high-frequency signal by the TIL117 photoelectrical coupler, improve transfer efficiency.

(3), the receiving end controller transmits data division to host computer: the data upload after the receiving end controller calculates process by 485 communication modules is given host computer, receive 485 modules in the communications portion of this communication module and transmission and receiving end, through time-sharing multiplex after the software processes, and at the receiving end of host computer, should adopt one 485 signal to change the RS-232 signal processing module, the Transistor-Transistor Logic level signal that single-chip microcomputer is uploaded by receiving end 485 communication modules, convert the RS-232 signal that PC can be discerned to, the information that collects host computer can in time be handled.

(4), host computer PC control and reception data division: host computer PC sends instruction code by the serial ports Control Software single-chip microcomputer is controlled.

Usefulness of the present invention is: native system can be by accurately measuring, error amount is between 1mm to 2mm, satisfy the examination criteria of cloth, and hole, overshoot length in testing out cloth, whether occur, produce alerting signal during less than specified length, thereby there is to solve effectively that measuring error is bigger than normal to be caused the problem that product qualified rate reduces.

(4) description of drawings

Accompanying drawing is the functional block diagram of native system.

(5) embodiment

Below in conjunction with embodiment technical scheme of the present invention is described further.

The technical scheme of the system of this programme is:
