It will be understood that terms such as "having," "including," and "comprising," as used herein, do not preclude the presence or addition of one or more other elements or groups thereof.
The present invention provides a test device of radio wave direction for measuring the arrival direction of external radio waves, for example, the arrival direction of radio waves radiated by a base station of a mobile phone network. The device for testing the direction of radio waves comprises a wireless communication device 1, a housing 2, a receiving antenna 3, a filter plate 4 and a connecting unit 5.
The technical solution of the present invention is described in detail below with reference to the accompanying drawings.
As shown in fig. 1, the present invention provides a device for testing the direction of radio waves, which includes a receiving antenna for receiving radio waves, a filter plate connected to the receiving antenna, a shielding housing connected to the filter plate, a wireless communication device disposed in the shielding housing and connected to the shielding housing, and a connecting assembly; the connecting assembly comprises two parts, wherein the first part is connected with the receiving antenna and the filter plate, and the second part is connected with the filter plate and the coaxial connector outside the shielding shell; the wireless communication device is connected to a coaxial connector inside the shielded enclosure.
Specifically, a receiving antenna for receiving a radio wave of which direction is to be determined must have a wide bandwidth and strong directivity, such as a log-periodic antenna.
Specifically, the wireless communication device may detect the strength of the received signal, and may include a position sensor and an acceleration sensor, and may record the detected signal strength and the position information of the device. The device may also have a screen on which signal strength and location information can be displayed in real time.
Further, the position sensor and the acceleration sensor are used for measuring the position and the angle information of the equipment. When the intensity of the radio wave is measured, the intensity of the received radio wave is stored in the memory in association with information of time, place, angle, and the like.
A terminal capable of receiving an external radio wave radiated from a base station whose radio wave arrival direction is to be measured, for example, a radio wave of a 5G NR or 4G LTE or 3G network. Application software for displaying the intensity of a received radio wave on a screen is installed in the wireless communication device. The intensity of the received radio wave is displayed on a screen or stored in a memory in association with time, place, etc., and information such as the intensity of the radio wave can be transmitted to the outside via an interface such as USB.
When the intensity of the received radio wave is higher than a predetermined value, the wireless communication apparatus may notify the user that the intensity of the radio wave is high by a set sound or by means of a screen display. When a user using the radio wave measuring device S is carrying the device for testing, the intensity of the received radio wave is observed to vary in accordance with the positional relationship with the base station by changing the direction of the receiving antenna 3. The user can easily determine the arrival direction of the radio wave by the direction in which the intensity of the radio wave measured by the wireless communication apparatus increases.
In particular, the filter panel is a set of replaceable filters, each filter corresponding to a particular frequency range, the filters having low in-band insertion loss and high out-of-band rejection, and being capable of filtering signals received by the antenna, removing unwanted signal rates, and transmitting desired signals to the wireless communication device within the housing.
The filter board is provided with a standardized interface, so that a corresponding filter can be selected according to the frequency of a signal to be tested, or a filter can be built by itself, for example, when a base station signal of LTE B8 is tested, a filter of 925-plus-960 MHz can be selected, out-of-band useless signal rate is removed in advance, and useful signals between 925-plus-960 MHz are transmitted to the wireless communication equipment inside the housing. Similarly, when testing the 5G NRN41 signal, the filter corresponding to N41 may be selected.
In particular, the housing can house a wireless communication device, and the local site can further include a transparent member through which a screen of the wireless communication device located inside can be viewed. The housing portion and the transparent portion have a shield member for attenuating external radio waves, and the wireless communication device can be protected from external signals.
The shell 2 comprises a shell 21, a cover 22 and a transparent part 23, wherein the shell 21 is used for placing and fixing the wireless communication equipment 1, a coaxial connector is arranged on the side edge, the inner side of the connector is connected with the wireless communication equipment 1, and the outer side of the connector is a signal input end which can input signals from the outside. The transparent member 23 may be used to observe the received signal strength from the outside. The shell 21, the cover 22 and the transparent part 23 are all shielding parts, a circle of metal elastic sheet is arranged at the edge position 24 of the shell, when the cover 22 is covered, the shielding performance inside the shell can be ensured, and wave-absorbing materials can be added inside if necessary, so that the effect of attenuating radio waves is further enhanced.
In particular, the connection unit is used for receiving the antenna and the filter plate, as well as the filter plate and the wireless communication device, and the connection unit is intended to ensure continuity of the transmission impedance, for example, 50 ohms impedance is maintained from the antenna to the wireless communication device.
The following specific methods of use of the invention:
when the user measures, the arrival direction of the external radio wave can be judged using the test device of the radio wave direction in the following steps.
First, the user opens the measurement application software of the wireless communication device 1, then fixes it in the housing 2 and closes the cover 22.
Secondly, the user can store the intensity of the external radio wave at different positions and directions in the storage medium by changing the position and direction of the external receiving antenna 3, and simultaneously read the information of the position sensor and the acceleration sensor and record the information together.
While embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments. It can be applied to all kinds of fields suitable for the present invention. Additional modifications will readily occur to those skilled in the art. It is therefore intended that the invention not be limited to the exact details and illustrations described and illustrated herein, but fall within the scope of the appended claims and equivalents thereof.
