Description

Technical Field

[0001] The present invention relates to the technical field of radar antenna testing, and in particular to a phased array antenna testing device with radiation protection. Background Art

[0002] A phased array antenna refers to an antenna that changes the phase of the radiation units in the array by an electronic control method so that the beam scans the space as required. When testing a phased array antenna, it is usually carried out in an anechoic chamber. However, the space of the anechoic chamber is limited, and testers often accidentally enter the radiation area, resulting in radiation damage to the testers who enter by mistake.

[0003] Therefore, the current phased array antenna testing device has insufficient safety and is prone to cause radiation damage to testers who enter by mistake. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a phased array antenna testing device with radiation protection to solve the problem that the current phased array antenna testing device has insufficient safety and is prone to cause radiation damage to testers who enter by mistake.

[0005] According to the first aspect of the embodiments of the present invention, a phased array antenna testing device with radiation protection is provided, including: A host computer, a beam control box, a phased array antenna, a horn, a power meter, a spectrum analyzer, and a first human body sensor; The host computer, the beam control box, and the phased array antenna are connected in sequence. The host computer is used to provide a human-computer interaction operation platform. The beam control box is used to generate a pulse emission signal. The phased array antenna is used to emit a radiation signal according to the pulse emission signal; The horn is respectively connected to the power meter and the spectrum analyzer. The horn is used to receive the radiation signal and transmit the radiation signal to the power meter and the spectrum analyzer respectively; The first human body sensor is connected to the beam control box and is used to generate a first induction signal when there is a human body in the preset radiation area and transmit the first induction signal to the beam control box. If the beam control box receives the first induction signal, it stops generating the pulse emission signal. If the beam control box does not receive the first induction signal, it generates the pulse emission signal.

[0006] Preferably, the phased array antenna testing device with radiation protection further includes: An alarm connected to the first human body sensor; The first human body sensor is further used to transmit the first induction signal to the alarm when generating the first induction signal; The alarm is used to give an alarm according to a preset alarm mode when receiving the first induction signal.

[0007] Preferably, the phased array antenna test device for anti-radiation further includes: A second human body sensor; the second human body sensor is connected to the alarm. The second human body sensor is used to generate a second induction signal when there is a human body in a preset early warning area, and transmit the second induction signal to the alarm. The alarm is used to give an alarm according to a preset early warning mode when receiving the second induction signal.

[0008] Preferably, the phased array antenna includes: A wave control motherboard, a beam amplifier and an antenna array surface connected in sequence.

[0009] Preferably, the alarm is an audible and visual alarm.

[0010] The technical solutions provided by the embodiments of the present invention may include the following beneficial effects: It can be understood that in the phased array antenna test device for anti-radiation shown in the present invention, the upper computer provides a man-machine interaction operation platform, the beam control box generates a pulse emission signal, and the phased array antenna emits a radiation signal; the horn receives the radiation signal and transmits it to the power meter and the spectrum analyzer respectively; the human body sensor is used to sense and identify a preset radiation area. When it is recognized that a human body enters the preset radiation area, an induction signal is generated. If the beam control box receives the induction signal, it stops generating the pulse emission signal. If it does not receive the first induction signal, it generates the pulse emission signal. It can be understood that in this technical solution, when the tester enters the preset radiation area, the beam control box stops generating the pulse emission signal and pauses the emission of the radiation signal. When the tester leaves the preset radiation area, the beam control box automatically resumes work, improving the safety of the test device and ensuring the safety of the tester.

[0011] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The drawings here are incorporated into the specification and form a part of this specification, showing embodiments consistent with the present invention and used together with the specification to explain the principles of the present invention.

[0013] Figure 1 is a schematic block diagram of a phased array antenna test device for anti-radiation shown according to an exemplary embodiment; Figure 2It is a schematic block diagram of another radiation-proof phased array antenna test device shown according to an exemplary embodiment. Detailed implementation manners

[0014] Here, the exemplary embodiments will be described in detail, and examples thereof are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0015] In one embodiment, Figure 1 It is a schematic block diagram of a radiation-proof phased array antenna test device shown according to an exemplary embodiment. Refer to Figure 1 A radiation-proof phased array antenna test device is provided, including: A host computer 10, a beam control box 20, a phased array antenna 30, a horn 40, a power meter 50, a spectrum analyzer 60, and a first human body sensor 70.

[0016] The host computer 10, the beam control box 20, and the phased array antenna 30 are connected in sequence. The host computer 10 is used to provide a man-machine interaction operation platform. The beam control box 20 is used to generate a pulse emission signal. The phased array antenna 30 is used to emit a radiation signal according to the pulse emission signal.

[0017] The horn 40 is respectively connected to the power meter 50 and the spectrum analyzer 60. The horn 40 is used to receive the radiation signal and respectively transmit the radiation signal to the power meter 50 and the spectrum analyzer 60.

[0018] The first human body sensor 70 is connected to the beam control box 20 and is used to generate a first induction signal when there is a human body in a preset radiation area and transmit the first induction signal to the beam control box 20. If the beam control box 20 receives the first induction signal, it stops generating the pulse emission signal. If the beam control box 20 does not receive the first induction signal, it generates the pulse emission signal.

[0019] In specific practice, the host computer 10 is a man-machine interaction operation platform provided for the operation and function debugging of the wave control system, and mainly completes functions such as Flash data reading and writing, single-channel amplitude-phase control, status reading, power supply control, and angle sending. The beam control box 20 can generate the required pulse emission signal.

[0020] After the test starts, since the beam control box 20 continuously generates pulse emission signals, the phased array antenna 30 will continuously generate radiation signals within the radiation area. If a tester accidentally enters the radiation area during the test, the human body sensor will generate an induction signal. After receiving the induction signal, the beam control box 20 stops generating pulse emission signals, and the radiation within the radiation area will also disappear. After the tester leaves the radiation area, the human body sensor cannot sense the human body, so no induction signal will be generated. If the beam control box 20 does not receive the induction signal, it will continue to resume generating pulse emission signals.

[0021] It can be understood that in this technical solution, when a tester enters the preset radiation area, the beam control box 20 stops generating pulse emission signals and pauses the emission of radiation signals. When the tester leaves the preset radiation area, the beam control box 20 automatically resumes operation, improving the safety of the test device and ensuring the safety of the tester.

[0022] It should be noted that the anti-radiation phased array antenna 30 test device further includes: An alarm 80 connected to the first human body sensor 70; the first human body sensor 70 is also used to transmit the first induction signal to the alarm 80 when the first induction signal is generated; the alarm 80 is used to alarm according to a preset alarm method when receiving the first induction signal.

[0023] In specific practice, if a tester accidentally enters the radiation area, although the radiation stops, it will inevitably lead to a reduction in work efficiency. Therefore, the time for the beam control box 20 to stop generating pulse emission signals should be minimized as much as possible. In this embodiment, by setting an alarm, the alarm can alarm when a tester accidentally enters the radiation area. The tester will know that they have entered the radiation area and will therefore leave the radiation area as soon as possible, thereby reducing the time for the beam control box 20 to stop generating pulse emission signals and indirectly improving the test efficiency of the phased array antenna 30.

[0024] It should be noted that referring to Figure 2 , the anti-radiation phased array antenna test device further includes: A second human body sensor 90; the second human body sensor 90 is connected to the alarm 80.

[0025] The second human body sensor 90 is used to generate a second induction signal when there is a human body in the preset early warning area and transmit the second induction signal to the alarm 80.

[0026] The alarm 80 is used to alarm according to a preset early warning method when receiving the second induction signal.

[0027] In specific practice, a warning area larger than the radiation area can be set, and the second human body sensor 90 is used to sense the human body in the warning area. If a tester enters the warning area, a second induction signal will be generated. When the alarm 80 receives the second induction signal, it will alarm according to a preset warning method.

[0028] It can be understood that in the technical solution shown in this embodiment, when a tester enters the warning area, the alarm 80 will directly alarm in a preset warning manner. At this time, since the tester has not entered the radiation area, the first human body sensor 70 will not generate a first induction signal, the beam control box 20 will not stop generating the pulse emission signal, and the phased array antenna 30 test will not stop. At this time, the tester can walk out of the warning area when feeling the alarm signal. In this way, it is possible to avoid affecting the test efficiency to the greatest extent while ensuring the safety of the tester.

[0029] It should be noted that the phased array antenna 30 includes: A wave control motherboard 301, a beam amplifier 302, and an antenna array 303 that are connected in sequence.

[0030] It should be noted that the alarm 80 is an audible and visual alarm 80.
