Abstract
The utility model relates to an infrared-sensing limited liquid level sensor. An infrared sensor arranged on an upper limited liquid level and an infrared sensor arranged on a lower limited liquid level are respectively are installed on the top and the bottom of a slide way positioned near a glass tube level gage to monitor the height position of a reflecting floater in a glass tube. The utility model is connected with a computer via an adapter module arranged in an interface box. The visual inspection and manual adjustment operation of operators are replaced, and the entire checking process is accommodated in a computer-controlled closed-loop feedback system. Liquid level is kept in an optimum production operating condition all along to achieve the purposes of energy saving and high efficiency. The device has the advantages of simple structure, high anti-interference capability, convenient use and reliability.
Description
The utility model relates to and a kind ofly comes whether the reach capacity sensor of position of sensed level with infrared light, belongs to the sensor in the electromechanical integration technology system and the technical field of configuration thereof.
Rebuild traditional industry with electronic technology, computer technology, make the traditional industry of large-scale production break away from heaviness, dirty tired craft or semi-hand operation, make it to produce equipment and realize mechanization, electronization, robotization, to reach the purpose of energy-conservation, material-saving, raising work efficiency and product quality, this is the important technology transformation task of China's Eighth Five-Year Plan.The new problem of pendulum in face of the engineering technical personnel of industry-by-industry is exactly how the conventional basic device of various original employing manual observations, utilize some to adopt new unit, the new equipment of hi-tech manufacturing to replace, thereby realize the automatic adjusting control of production run, make it to be in all the time operation operation under the optimum process condition, realize optimal production effect of getting twice the result with half the effort.
The purpose of this utility model provides a kind of existing high-tech product--infrared detection device that makes full use of, and constitutes the responsive harvester of a cover limit liquid level, and makes it to become the basic acquisition circuit in the electromechanical integration control system.
The utility model is achieved in that in common glass-tube liquid level gauge the reflection float is housed, and slide rail is arranged at the local device of contiguous glass-tube liquid level gauge, an infrared detection device that is in upper limit liquid level and bottom limit level is equipped with at two places up and down on this slide rail respectively, these two infrared detection devices link to each other with the level shifting circuit chip by lead, the output of this level shifting circuit chip is connected to and is inserted in universal standard industrial control interface case mileage word signal adaptation module, and the interface case then is connected with computing machine.
The utility model mainly is to be used to replace conventional gaging glass collecting unit, replace operating personnel's visual inspection and the operation of adjusting thereupon, make whole observation, adjustment process include robotization, digitizing, intelligentized closed-loop control system in, can guarantee at any time that liquid level is in best production status all the time, reach energy-conservation, production purpose efficiently.
Hardware of the present utility model constitutes as shown in Figure 1, and the 1st, conventional common glass-tube liquid level gauge, its installation does not have any specific (special) requirements.The 2nd, the reflection float, it is placed in the glass-tube liquid level gauge, is on the liquid level face at liquid level top, and fluctuates with the lifting of liquid level.The 3rd, at the slide rail that the place of contiguous glass-tube liquid level gauge is provided with, infrared detection device can move up and down along slide rail 3, adjustment and fastening location.4, the 5th, be in the infrared detection device of two limit liquid levels of limes superiors, smallest limit respectively, this infrared sensing idol part is an approved product, domesticly can produce now, and its product type is GC-313, GC-323, and can buy from domestic electronic devices and components market.What change that the infrared photodiode idol part of its resistance forms according to the Infrared that reflects that receives by an infrarede emitting diode and energy for it.The 6th, the level shifting circuit chip.Link to each other with above-mentioned two infrared sensings idol part by lead, its output is connected to the responsive adaptation module 8 of universal industrial control interface case 7 mileage word switch amounts of the standard of being inserted in again by cable, delivered in the computing machine 9 and handle gathering the responsive liquid level physical quantity signals that come by module 8.Form the electromechanical integration standard acquisition loop that replaces manual observation glass tube liquid level thus.The responsive adaptation module 8 of digital switch quantity can be selected the IAC5 model for use, and this is the typing universal product of U.S. OPT22 company.
Principle of work of the present utility model is: when the reflection float 2 at liquid level top enters its monitored position in being in container, infrared detection device 4, the Infrared that 5 li light emitting diode sends can be through the reflection of float 2 and is made the photodiode in it be low resistive state (during the no reflection events infrared light, diode is high-impedance state), through chip 6 incoming signal level from sensing device is converted to logic signal levels and (reflex time output high level is arranged, output low level during no reflection events) adaptation module 8 is delivered in output, can also be inserted with the adaptation module of the actuator of control liquid level height in 7 li in interface case, like this, the aggregation process of machine 9 as calculated, not only can be by the responsive status signal of infrared detection device to the liquid level height, and send control corresponding by the adaptation module in the interface case to actuator and instruct, adjust liquid level position at random, constitute the industrial process control system of the closed-loop control of a cover electromechanical integration.This cover sensing device can replace the measurement equipment of the liquid position in the containers such as manual control boiler, reacting furnace fully.And because the infrared frequency good stability can not be subjected to the influence of available light or artificial light light, antijamming capability is strong, guarantees that responsive data are reliable, thereby guarantees whole Process Control System security of operation and be in optimum condition.
