Description
Technical field
The utility model is related to a kind of test device, especially a kind of radio function test device.The utility model also relates to
And the radio function including above-mentioned radio function test device tests system.
Background technology
With the development of internet and cloud, existing temperature controller, controller etc. are used for the equipment or use of Heating,Ventilating and Air Conditioning
Usually there is radio function in the equipment of building automatic.For this equipment with radio function, the survey of radio function
Examination is also the steps necessary before product export.However, the test of this radio function needs the interference in face of many factors, such as
The interference of other electromagnetic radiation in space, interfered caused by interference caused by encapsulation and antenna failure itself etc..At present right
Multiple test devices are needed when the radio function test of equipment, while needing more test equipments, cost is higher and is inconvenient to make
With.
Utility model content
The purpose of this utility model is to provide a kind of radio function test device, can only lean on a test device realization pair
Such as the building automation device of temperature controller carries out radio function test, it is easy to operate while reducing testing cost.
The another object of the utility model is to provide a kind of radio function test system, can only lean on a test device reality
Radio function test now is carried out to the building automation device of such as temperature controller, it is easy to operate while reducing testing cost.
The radio function test device of the utility model, including a shielded box, a measurement jig, a signal transmitting and receiving
Module and an antenna circuit board.Measurement jig is set in shielded box comprising a pedestal, a holder, a test
Pressing plate and several first probes.There are one test surfaces, part to be measured is placed on test surfaces pedestal tool.Holder is set to test surfaces.It surveys
Pressure testing plate be set to holder and can along perpendicular to the direction of test surfaces relative to base motions.First probe is set to test pressure
Plate and towards test surfaces, the first probe can be connect with test presser motion and with part signal to be measured.Signal transmitting and receiving module is arranged
In measurement jig, signal transmitting and receiving module is connect with the first probe wire signal, and signal transmitting and receiving module by signal is connected to outside shielded box
Portion.Antenna circuit board is set to measurement jig and network topology testing face, and antenna circuit board can be connect with part wireless signal to be measured, day
Line circuit board signal is connected to outside shielded box.
Radio function test device provided by the utility model, including a shielded box, measurement jig are set to shielded box
In, part to be measured is placed on measurement jig, to which the wireless signal transfer during wireless test carries out completely in shielded box, is shielded
Cover external electromagnetic interference.Radio function test device can be made to be measured in shielded box by the first probe and signal transmitting and receiving module
Part and shielded box PERCOM peripheral communication, in shielded box external connection test equipment, to the wireless of part to be measured (such as circuit board)
Module is tested.Meanwhile radio function test device can also be made by antenna circuit board part to be measured in shielded box with
Test equipment outside shielded box is communicated, to carry out product-level wireless test.Radio function test device only leans on one
Test device is realized carries out radio function test to temperature controller, easy to operate while reducing testing cost.
In another exemplary embodiment of radio function test device, part to be measured is circuit board, and measurement jig is also
Including a dismountable working plate, test surfaces can be set to, several vertically disposed positioning columns are formed on working plate,
For being positioned to part to be measured, convenient for the first probe precise contact, increase the reliability of test.
In another exemplary embodiment of radio function test device, test pressing plate further includes a pair of of sliding rail, is waited for
Test pressing plate can be fixed on by sliding rail by surveying part.Sliding rail is used to position part to be measured, and it is opposite with antenna circuit board to control it
Position increases the reliability of test.
In another exemplary embodiment of radio function test device, measurement jig further includes several second spies
Needle, is set to test pressing plate and towards test surfaces, the second probe signals are connected to outside shielded box and can believe with part to be measured
Number connection.Part to be measured can receive and dispatch control signal by the second probe, for testing to part to be measured.
In another exemplary embodiment of radio function test device, measurement jig further includes a quickly folder
Tool, quick-speed jigs can drive test presser motion, and pressing plate is tested compared to manual actuation, and operation quick-speed jigs are more convenient accurate,
Improve testing efficiency.
In another exemplary embodiment of radio function test device, radio function test device further includes one
Antenna protection box is set to test surfaces, and antenna circuit board is set in antenna protection box, and antenna protection box was for testing
Antenna circuit board is protected in journey, increases testing reliability.
In another exemplary embodiment of radio function test device, shielded box is cuboid aluminium case comprising
One babinet and a upper cover, upper cover is hinged with babinet, and air spring is provided between upper cover and babinet.
The utility model also provides a kind of radio function test system, including a test equipment and one it is above-mentioned wireless
Device for testing functions.Test equipment can send with gathered data signal, and to collected data-signal test.Signal transmitting and receiving
Module and antenna circuit board are connect outside shielded box with test device signal respectively, and test equipment passes through signal transmitting and receiving module and day
Line circuit board is sent to part to be measured and gathered data signal, and tests collected data-signal.
In another exemplary embodiment of radio function test device, part to be measured is the temperature control with radio function
Device, or the hardware circuit board with radio function.
Hereafter by a manner of clearly understandable, preferred embodiment is described with reference to the drawings, to radio function test device and nothing
Above-mentioned characteristic, technical characteristic, advantage and its realization method of line function test system are further described.
