[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The present invention provides Figure 1-9 A satellite communication load ground detection system shown in the figure includes a test device and an interference device. The test device includes a storage cabinet 1 and a satellite communication load tester 4. The model of the satellite communication load tester 4 can be 5252D-H. The satellite communication load tester 4 is placed inside the storage cabinet 1. The front side of the satellite communication load tester 4 is provided with a plurality of external interfaces 7. An indicator light 9 fixed on the satellite communication load tester 4 is provided above each external interface 7. During the test, the satellite communication load tester 4 can be a professional instrument that supports satellite load testing in the 17~21 GHz, 27~31 GHz, 36~43GHz, and 46~52 GHz frequency bands. It acts as an excitation source in satellite load testing. Users can choose according to specific frequency band requirements. The satellite communication load tester 4 can be widely used in satellite load amplifier, mixer and other tests to meet the test requirements in the development and production of high-power amplifiers and mixers. During the test, the external interface 7 on the satellite communication load tester 4 is connected to other related equipment including a computer through a line. Under the control of the computer, the satellite communication load tester 4 simulates the signal reception and transmission during the satellite communication process, verifies the communication capability of the load, and tests the load's ability to process and store received data to ensure the integrity and accuracy of the data. In addition, it can also verify the load's ability to respond to trigger signals and control instructions to ensure that it can operate according to ground instructions.

[0027] The storage cabinet 1 is provided with a cabinet door 3 on the front side through a hinge, and a controller 5 and a plurality of indicator buttons 6 are provided on the rear side of the cabinet door 3. The indicator buttons 6 correspond to the external interfaces 7 one by one. The indicator buttons 6 are connected to the input end of the controller 5, and the indicator lights 9 are connected to the output end of the controller 5, so that the indicator buttons 6 are connected to the indicator lights 9 of the corresponding external interfaces 7 through the controller 5. The information of the corresponding external interfaces 7 is marked on the indicator buttons 6. After pressing the indicator buttons 6, the indicator lights 9 above the corresponding external interfaces 7 will light up.

[0028] In the idle state before the test starts, the cabinet door 3 is in the closed state, and in the working state, the cabinet door 3 is opened. The first step before the test starts is to connect each line with the corresponding external interface 7 on the satellite communication load tester 4 through the plug, and the external interface 7 corresponds to the indication button 6 one by one, and the corresponding indication button 6 has the relevant information of the external interface 7 written on it. In order to plug the plug into the correct external interface 7, press the corresponding indication button 6 according to the information on the indication button 6, and under the control of the controller 5, the indicator light 9 above the corresponding external interface 7 will light up, and the position of the corresponding external interface 7 can be judged by the position of the lit indicator light 9, so that the plug can be correctly plugged into the external interface 7; Since the indicator button 6 is fixed on the cabinet door 3, there are fewer space restrictions. In this way, the indicator button 6 can be made larger so that there is enough space to clearly mark the information. Controlling the indicator light 9 by the indicator button 6 can ensure that the wiring position is correct, making the wiring work more convenient.

[0029] In the working state, each external interface 7 is plugged with a corresponding plug. In order to fix the plug, Figure 4 , 5 As shown, a reinforcement component 8 is provided under each external interface 7, and the reinforcement component 8 includes a fixed shaft 801, and the fixed shaft 801 is located under the corresponding external interface 7. Both ends of the fixed shaft 801 are rotatably connected with protrusions 802, and the protrusions 802 are fixed on the satellite communication load tester 4. Therefore, the reinforcement component 8 is fixed to the bottom of the external interface 7 of the satellite communication load tester 4 through the protrusions 802; in other embodiments, the reinforcement component 8 can also be only above, to the side, etc. of the external interface 7.

[0030] Two pressure rods 804 are fixedly provided at the outer end of the fixed shaft 801, and the distance between the two pressure rods 804 is smaller than the width of the joint corresponding to the external interface 7. Torsion springs 803 are provided at both ends of the fixed shaft 801. One end of the torsion spring 803 is fixedly connected to the protrusion 802 on the corresponding side, and the other end is fixedly provided with an annular protrusion 805, which is fixed to the outer end of the fixed shaft 801.

[0031] When the connector is plugged into the corresponding external interface 7, in order to prevent the connector from loosening, the friction between the connector and the external interface 7 is designed to be relatively large in the prior art, so the resistance of the connector when inserted or unplugged is relatively large. Therefore, when plugging and unplugging, one hand is required to fix the satellite communication load tester 4 to prevent the satellite communication load tester 4 from being driven; The test device of the present invention sets the resistance when the connector is plugged in and out to be relatively small, which saves effort when plugging in and out. Before plugging in, the fixed shaft 801 is rotated to tighten the torsion spring 803. The rotation of the fixed shaft 801 causes the pressure rod 804 originally located on the front side of the external interface 7 to move away. When the connector is inserted into the external interface 7 and fixed, the fixed shaft 801 is loosened, and the elastic force of the torsion spring 803 is released, driving the fixed shaft 801 and the pressure rod 804 to rotate. Since the spacing between the pressure rods 804 is smaller than the width of the connector, the connecting line corresponding to the connector can pass between the two pressure rods 804, but the connector cannot pass through. Therefore, the pressure rod 804 cannot rotate back to its original position, but is stuck at the outer end of the connector and applies pressure to the connector to make it plugged tightly on the external interface 7. In this way, the plugging and unplugging of the connector is more labor-saving, and there is no need to fix the satellite communication load tester 4. At the same time, the connector is prevented from loosening during use.

[0032] In order to facilitate the detection, Figure 1 , 2 As shown in , 6 , a plurality of universal wheels are fixedly provided at the bottom end of the storage cabinet 1 to facilitate the movement of the storage cabinet 1 . A workbench 2 is provided at one side of the storage cabinet 1 . The workbench 2 includes a support plate 201 . One end of the support plate 201 is hinged to one side of the storage cabinet 1 .

[0033] After the support plate 201 is unfolded, two groups of support rods 203 of equal length are provided at the bottom. The support rods 203 of the same group can be Figure 2 As shown, there are multiple sections, and the multiple sections of support rods are connected end to end. The connection between two adjacent sections of support rods 203 is provided with a connecting ring 204 through a threaded sleeve, which can be easily disassembled and can be adjusted according to the required height; A bottom plate 202 is provided at the bottom of the support plate 201 , and two groups of support rods 203 are provided between the bottom plate 202 and the support plate 201 . The disassembled support rods 203 , the connecting rings 204 and the bottom plate 202 can all be stored inside the storage cabinet 1 .

[0034] When idle, the pallet 201 naturally droops and folds on one side of the storage cabinet 1 without taking up too much space. When working, open the cabinet door 3 and take out the bottom plate 202, support rods 203 and connecting rings 204 placed inside the storage cabinet 1. Connect the support rods 203 end to end through the connecting rings 204 to assemble two groups of support rods 203. Then rotate the pallet 201 to convert it into a horizontal state, install the two groups of support rods 203 at the bottom end of the pallet 201, and then connect and fix the bottom ends of the two groups of support rods 203 on the bottom plate 202. The bottom plate 202 is placed on a flat ground, and the pallet 201 is supported by the bottom plate 202 and the support rods 203 to maintain a horizontal state. In this state, relevant instruments and equipment used for testing can be placed on the pallet 201, making the testing more convenient.

[0035] The anti-interference capability of satellite communication payloads also needs to be tested, such as Figure 8 , 9 As shown, the jammer includes a hollow mounting plate 10, a top of which is provided with a detachable satellite communication jammer 11. The model of the satellite communication jammer 11 may be QMA-4FD. The satellite communication jammer 11 is connected to a control panel 12 via a data cable, and the satellite communication jammer 11 can be adjusted via the control panel 12.

[0036] The hollow mounting plate 10 has a cavity 14, and the outer end of the central control mounting plate 10 is connected to an air duct with a valve, the air duct is communicated with the cavity 14 of the hollow mounting plate 10, a plurality of adsorption plates 13 are fixedly provided at the bottom end of the hollow mounting plate 10, the top end of the adsorption plate 13 is communicated with the cavity 14 of the hollow mounting plate 10, the internal air pressure of all the adsorption plates 13 is equal, and a rubber ring which plays a sealing role is fixedly provided at the bottom end of the adsorption plate 13.

[0037] In addition to basic tests, ground tests also require testing of the anti-interference ability of satellite communication payloads. During the test, the adsorption plate 13 at the bottom of the hollow mounting plate 10 is buckled on the roof of the car, and the rubber ring at the bottom of the adsorption plate 13 is in close contact with the flat roof, thereby closing the adsorption plate 13. Then, the air in the cavity 14 of the hollow mounting plate 10 is extracted using an air duct, so that negative pressure is generated in the cavity 14. The adsorption plate 13 is negatively pressurized and the hollow mounting plate 10 is adsorbed and fixed on the roof. The satellite communication jammer 11 at the top of the hollow mounting plate 10 is also fixed on the roof of the car. While fixing it on the roof, it is necessary to ensure compliance with traffic regulations; The control panel 12 is connected to the satellite communication jammer 11 through a data cable, and one end of the data cable extends into the car through the car window, so that the tester can control the satellite communication jammer 11 through the control panel 12 in the car. After the test officially starts, the tester drives the car so that the jammer fixed on the car gradually moves away from the test device. At the same time, the satellite communication jammer 11 interferes with the signal of the satellite communication payload. The interference is only targeted at specific frequencies and produces unnecessary effects. In this way, the anti-interference ability of the satellite communication payload is tested. The reason why the jammer is fixed on the car is to be able to quickly and conveniently adjust the distance between the jammer and the test device, so as to test the anti-interference ability at different distances and make the test more comprehensive.

[0038] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
