The shielding module is a metal shielding frame provided with a substrate and a sealing metal shell metal shell, the good technical effect of the utility model is as follows: avoiding a outside signal disturbing a radio-frequency signal in a test, improving the reliability of a test result, enhancing the consistency of the effective communication distance of a radio frequency card reader.
Description
Technical field
The utility model relates to a kind of test macro, relates in particular to a kind of radio frequency test system.
Background technology
RFID (Radio Frequency Identification, radio-frequency (RF) identification) be applied in people's life increasingly extensively, RFID card reader is the important component part during mobile RFID arranges, people control communication distance with low frequency signal conventionally, and low frequency signal emissive power has determined effective communication distance.But in the test process of low frequency signal emissive power, low frequency signal all can be subject to the electromagnetic interference (EMI) in test environment to some extent, reduce the reliability of test result, even obtained final test data by uniformity test plate, also can cause the inconsistent situation of actual effective communication distance to produce.
Utility model content
The purpose of this utility model is to provide a kind of radio frequency test system, prevents from being subject to the impact of electromagnetic interference (EMI) in the process of carrying out radio frequency testing, solves the shortcoming that prior art exists.
The utility model adopts following technical scheme to realize:
A kind of radio frequency test system, this system comprises RFID label and radio-frequency card reader, it is characterized in that, described radio-frequency card reader is arranged on an adjustment tester, described label adjusting gear is for adjusting the low frequency signal emissive power of radio-frequency card reader, described radio-frequency card reader is connected with a low frequency uniformity test plate, RFID label, radio-frequency card reader and low frequency uniformity test plate are all arranged in a shroud module, described radio-frequency card reader is connected with demonstration output module with a supply module, and described low frequency uniformity test plate is connected with host computer.
Further, described shroud module is a metallic shield framework, on described metallic shield framework, be provided with substrate and sealing metal shell, RFID label, radio-frequency card reader and low frequency uniformity test plate are fixedly mounted on substrate, and be positioned over the inside of described sealing metal shell, described shroud module is by the earth point ground connection on substrate, and sealing metal shell is welded on substrate.
The useful technique effect that the utility model possesses is: avoided the interference of the outer signals in test process to the radiofrequency signal in test, improved the reliability of test result, improved the consistance of the effective communication distance of radio-frequency card reader.
Accompanying drawing explanation
Fig. 1 is the general frame figure of the utility model radio frequency test system.
Embodiment
By the description to embodiment below; to more contribute to public understanding the utility model; but specific embodiment given applicant can't be considered as to the restriction to technical solutions of the utility model, any definition to parts or technical characterictic change and/or to one-piece construction do form and immaterial conversion all should be considered as the protection domain that the technical solution of the utility model limits.
As shown in Figure 1, radio frequency test system comprises RFID label and radio-frequency card reader, radio-frequency card reader is arranged on an adjustment tester, label adjusting gear is for adjusting the low frequency signal emissive power of radio-frequency card reader, and according to the low frequency seat number emissive power of test result adjustment radio-frequency card reader, radio-frequency card reader is connected with a demonstration output module with a supply module, show that output module can be preferably LCD screen, can be kind for checking the connection of circuit, certainly also need other peripheral circuits, the design of peripheral circuit is well-known to those skilled in the art, therefore needn't repeat at this.In the time carrying out system testing, the distance between label adjusting gear and radio-frequency card reader pre-sets, and is roughly equivalent to the communication distance thresholding of the low frequency signal of radio-frequency card reader.Label adjusting gear is the very ripe device of widespread use on market, and the low frequency signal intensity that its test obtains is exactly the low frequency signal intensity at this communication distance thresholding place.Radio-frequency card reader is connected with a low frequency uniformity test plate, RFID label, radio-frequency card reader and low frequency uniformity test plate are all arranged in a shroud module, radio-frequency card reader is connected with demonstration output module with a supply module, low frequency uniformity test plate is connected with host computer, and commissioning staff is operated and monitors low frequency uniformity test plate by operation host computer.Low frequency uniformity test plate is so-called TB plate, can in TB plate, pre-set the low frequency signal intensity corresponding with the communication distance thresholding of the low frequency signal of radio-frequency card reader to be measured, at predetermined communication distance thresholding place, the low frequency signal intensity that radio-frequency card reader is launched equals normal intensity, when test, to see whether low frequency signal intensity and normal intensity exist deviation, , with the absolute value of the test low frequency signal intensity of gained and the difference of normal intensity divided by normal intensity, the business of gained is multiplied by 100% again can obtain deviation, can judge by this deviate whether this radio-frequency card reader is specification product.Shield assembly can be the shielded box that an inwall is coated with absorbing material, can be also the metallic shield framework in embodiment below.No matter be the shielded box that inwall is coated with absorbing material, or metallic shield framework, be all designed to be able to absorb other electromagnetic waves except low frequency signal wave band, avoid outer signals that test macro is produced and disturbed.
In another embodiment, shroud module is a metallic shield framework, on metallic shield framework, be provided with substrate and sealing metal shell, RFID label, radio-frequency card reader and low frequency uniformity test plate are fixedly mounted on substrate, and be positioned over the inside of described sealing metal shell, described shroud module is by the earth point ground connection on substrate, and sealing metal shell is welded on substrate.
Certainly; the utility model can also have other various embodiments; in the situation that not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
