Abstract
The present invention relates to a high-speed wire temperature meter which belongs to the technology of temperature measuring instruments and meters and is composed of a prism spectroscope, a photoelectric convertor, a preamplifier, an analogue-digital convertor, a microcomputer data processing system, a digital-analogue conversion and output circuit and a power supply circuit. The microcomputer data processing system adopts data programming processing, the values of the analogue-digital convertor are set to be n-th-order and are ordered from large values to small values, the average of the values is obtained after the maximum value and the minimal value are removed, and m temperature values can be worked out and the maximum value is taken. If the maximum value is in the temperature range of the rolling, the temperature value is output, and if not, a lower limiting value is output. The present invention has accurate measuring temperature, controls a wire system shaking at high speed, and can both measure thick rods and high-speed wires at the speed of 60 m/s and with a diameter phi of 5mm.
Description
The present invention relates to temp measuring method, refer in particular to the method for high-speed rod being carried out thermometric.
At present, very difficult to the wire rod thermometric of high-speed cruising, particularly especially can't thermometric to thin footpath wire rod.The temperature measurer that high-speed rod uses in process of production, because the little measured target that requires of distance coefficient is big, when therefore measuring thin footpath wire rod, indicating value is inaccurate.Temperature signal is output as instant measured value, and in the face of the wire rod of high speed jittered, its temperature indicating value fluctuation is serious, can't participation system control.
The purpose of this invention is to provide and a kind ofly can carry out temperature survey the high-speed rod of little target and serious shake, output steadily, the high-speed rod temp measuring method of true temperature.
The object of the present invention is achieved like this, and it is made of Prism spectroscope, opto-electronic conversion, preposition amplification, analog to digital conversion, computer data processing system, digital-to-analog conversion and output and power circuit.(patent No.: 97222832.2) wherein the principal goods mirror is bonded by biconvex lens and recessed plano lens Prism spectroscope, detector plane output chromatogram light wave from Prism spectroscope, by opto-electronic conversion and computer data processing system computing, output and temperature corresponding simulating amount or digital quantity.Computer data processing system adopts the data program processing, and program circuit is:
(1) analog signal conversion through the electric signal of opto-electronic conversion, preposition amplification is become digital signal, conversion value is gathered n time.
(2) n signal is by ordering from big to small.
(3) deletion maximal value, minimum value are averaged again.
(4) mean value is changed into temperature value.
(5) the circulation said process is obtained m temperature value, takes out maximal value.
(6) as maximal value in the technological temperature scope of wire rod rolling, output corresponding simulating amount or digital quantity provide the corresponding temperature value.
(7) as maximal value not in the technological temperature scope, output corresponding simulating amount or digital quantity provide lower limit.
During work, this moisture apparatus is installed the location by the distance coefficient requirement, by Prism spectroscope, the temperature measurer that opto-electronic conversion, preposition amplification, modulus revolving die, computer data processing system, digital-to-analog conversion and output and power circuit constitute just can be measured high-speed rod real-time temperature value like this.
Advantage of the present invention is according to the requirement to energy of optical imaging concept and photoelectric sensor, the distance coefficient of this temperature measurer setting is 400: 1, be principal goods mirror range-to-go and the ratio of aimed dia is 400: 1, like this as long as the measured target effective diameter greater than Φ 1mm, can be measured its temperature value.High-speed rod meeting in service is constantly beated, as long as it is beated and does not exceed effective point for measuring temperature Φ 1mm, just can measure its temperature value.Thin directly wire rod, although most instant measured values is effective, because the wire rod high-speed motion, it is illegal number that individual data is still arranged, the repeatedly many group values of this instrument are carried out the data program processing by computer data processing system, to reach the accuracy of thermometric value.Can not only survey the thick bar of thick diameter, and can survey 60 meter per seconds well, wire rod is the high-speed rod of Φ 5mm directly, has satisfied the temperature measurement on-line requirement of wire rod, and temperature survey is accurate, and outstanding contribution is played in process automation to wire rod.
The present invention is described in detail below in conjunction with drawings and Examples.
Fig. 1 is principal goods mirror structural representation in the Prism spectroscope of the present invention.
Fig. 2 is opto-electronic conversion of the present invention, preposition amplification, analog to digital conversion, computer data processing system circuit diagram.
Fig. 3 is digital-to-analog conversion of the present invention and output circuit figure.
Fig. 4,5 is power circuit diagram of the present invention.

Fig. 7 measures view for Φ 5mm wire rod of the present invention.
This high-speed wire temperature meter is by Prism spectroscope, opto-electronic conversion, preposition amplification, analog to digital conversion, computer data processing system, digital-to-analog conversion and output and power circuit constitute, the principal goods mirror is bonded by biconvex lens 1 and recessed plano lens 2 in the Prism spectroscope, detector plane output chromatogram light wave from Prism spectroscope passes through opto-electronic conversion, preposition amplification, analog to digital conversion, the computer data processing system computing, digital-to-analog conversion, output and temperature corresponding simulating amount or digital quantity at last, computer data processing system adopts the data program processing, and program circuit is:
(1) analog signal conversion through the electric signal of opto-electronic conversion, preposition amplification is become digital signal conversion value sampling 20 times.
(2) 20 signals are by ordering from big to small.
(3) deletion maximal value, minimum value are averaged again.
(4) mean value is changed into temperature value.
(5) the circulation said process is obtained 20 temperature values, takes out maximal value.
(6) as maximal value in the technological temperature scope of wire rod rolling, output corresponding simulating amount or digital quantity provide the corresponding temperature value.
(7) as maximal value not in the technological temperature scope, output corresponding simulating amount or digital quantity provide lower limit.
With this temperature measurer the wire rod of the Φ 5mm diameter of high-speed cruising is carried out temperature survey, effective point for measuring temperature 3 among Fig. 7, the normal position 4 that Φ 5mm wire rod is not shaken, move 2mm position 5 on the Φ 5mm wire rod, Φ 5mm wire rod moves down the position 6 of 2mm, as can be seen from the figure, and when Φ 5mm wire rod is beated in ± 2mm scope, this temperature measurer can both accurately be measured its temperature value, satisfies the requirement of wire rod temperature measurement on-line.
