Abstract
The invention relates to a system for testing reflecting sensitivity of an electronic label, belonging to the technical field of testing the electronic label. A label testing plate is arranged in a fixed distance; the label can reach the critical work point through an edited software; the tested reflecting sensitivity is converted through a formula to acquire actual distance reading parameters. The system of the invention greatly simplifies the complex degree of the test, reduces the testing field, lightens the workload of the testers and decreases the interference of the external environment to the testing system; a wave absorbing screen is arranged to keep the reliability of the test so as to greatly save the testing cost; the testing effect of the system of the invention is consistent with the actual distance reading test without consuming force to draw the tested car; the operation is simple; the operators can operate the system by knowing the use of the software; a normal operator can operate through once training; thus the system improves the detecting speed, and solves the bottleneck in testing the label production; one label is tested by spending 20-50 seconds; the time for testing 20-50 electronic labels is less than 50 minutes; and the system of the invention has strong practical applicability.
Description
Technical field
The present invention relates to a kind of electronic tag and reflect the sensitivity test system, this system makes things convenient for the test of electronic tag correlated performance, belongs to the electronic tag technical field of measurement and test.
Background technology
Electronic tag is applied in growing field in recent years.Can electronic tag have an important performance parameter decision be applied in association area, determines whether this batch product conforms to quality requirements, the actual distance of reading that Here it is; At present; The electronic label read/write that the actual proving installation of reading distance is connected by computer and computer, vertical with electronic label read/write to the track that fixes on the ground, the dolly and the pull bar that is connected with dolly that move in orbit; The antenna that is fixed on the antenna holder constitutes, and antenna is connected with electronic label read/write.During test; Be attached to label on the transportable dolly earlier, the sky line parallel on the tested electronic tag on the dolly and the antenna holder is relative, its highly with antenna on same horizontal line; Spur the pull bar of moveable carriage then, observe computer and whether can detect the signal that tested electronic tag postbacks.There is more deficiency in existing proving installation: 1) one of the every test of label just needs the tester to take off the label of test last time, sticks new label, spurs the pull bar of moveable carriage simultaneously, and tester's physical consumption is big, fatiguability; 2) reading apart from scope between 1 meter to 5 meters of general electronic tag, this kind method of testing receives external environment influence big.As set up microwave dark room and eliminate environmental impact, exist cost high, it is complicated to measure flow process; 3) every BT(batch testing) need be measured 20 to 50 electronic tags, and each labeling requirement cost 2 minutes to 5 minutes is so every batch of measurement needs 1 hour to 3 hours approximately.Therefore be not difficult to find out that actual the reading of existing electronic tag is difficult to adapt to requirements of large-scale production apart from proving installation, is unfavorable for enhancing productivity and improving test mass.
Summary of the invention
The purpose of this invention is to provide a kind of electronic tag and reflect the sensitivity test system, solve existing actual reading and fall behind because of usefulness, exist to be difficult to adapt to requirements of large-scale production apart from proving installation; Be unfavorable for enhancing productivity and improve the defective of test mass,, under the support of corresponding software, simplify the complexity of label test through the present invention; Reduce test site; Alleviate tester's workload, reduce the interference of external environment, thereby greatly practice thrift testing cost for test macro; Adapt to requirements of large-scale production, help enhancing productivity and improving test mass.
The objective of the invention is to realize that a kind of electronic tag reflection sensitivity test system comprises Working gantry through following technical scheme; Host computer on the Working gantry and display screen, the electronic label read/write that is connected with host computer, the antenna that is connected with electronic label read/write; It is characterized in that; Fixing foamed cotton plate on the lateral surface of Working gantry, the foamed cotton plate spacing is provided with the label test board relatively, is fixed on center of antenna point and the tested height such as tag hub point grade on the label test board on the foamed cotton plate.
Foamed cotton plate spacing 30-150cm place is provided with the label test board relatively.
The one or both sides of label test board lateral or the setting of many sides are fixed with the suction ripple screen of universal rolling wheel.
The thickness of foamed cotton plate is 5-15cm.
The present invention is provided with the label test board through spacing, and actual the reading that becomes electronic tag is the reflection sensitivity test apart from parameter testing, after the formula conversion, obtains actual reading apart from parameter.The software control electronic label read/write that utilization of the present invention weaves is adjusted the output power of electronic label read/write to each Frequency point automatically in the working frequency range scope of regulation; Make label can reach critical working point, receive the reflection sensitivity of electronic tag simultaneously and show with figure.The present invention has greatly simplified the complexity of test; Reduced test site, alleviated tester's workload, reduced the interference of external environment for test macro; Inhale the reliability that the ripple screen has guaranteed test through putting, greatly practiced thrift testing cost.The present invention tests effect and actual reading apart from the test indifference.Need not to expend muscle power and draw tested dolly.Simple to operate, it is just passable that the operator only need be familiar with the use of software, and common operating personnel only need be trained once and just can be operated.Improve detection speed, solved the bottleneck of test during label is produced.Label of every survey only spends 20 seconds to 50 seconds, 20 of every measurements to time of 50 electronic tags less than 50 minutes, the present invention has very strong practicality.
