[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] At present, the traditional leaky cable test includes a signal source, a spectrum analyzer, an antenna, and a trolley required for moving the test antenna. During the test, it is necessary to manually move or control the trolley to measure the signal amplitude at each position along the leaky cable in turn, and then perform data processing. This process requires many manual steps, such as setting up the signal source and spectrum analyzer, and controlling the mobile trolley to reach different positions to record the corresponding data, which leads to low test efficiency and long test time, and cannot meet the needs of efficient leaky cable batch testing and ultra-long distance leaky cable testing.

[0031] Based on this, the present application proposes the following technical solutions, see below for details:

[0032] In one embodiment, Figure 1 As shown, Figure 1 A system architecture diagram of an automatic leaky coaxial cable testing system based on a wireless relay network provided in an embodiment of the present application; The present application provides an automatic leaky coaxial cable testing system based on a wireless relay network, and the system may include a signal source 2, a spectrum analyzer 3, a test antenna 4, a tracking vehicle 5, a wireless repeater 6 and a wireless computer 7.

[0033] The wireless repeater 6 is placed at the center of the leaky cable test site to construct a wireless local area network covering the entire leaky cable test site.

[0034] The signal source 2, the spectrum analyzer 3, the tracking vehicle 5 and the wireless computer 7 are all connected to the wireless local area network.

[0035] Among them, the input end of the signal source 2 is wirelessly connected to the wireless computer 7 through the wireless local area network, and the output end is connected to the leaky cable 1 to be tested, for receiving the first control instruction sent by the wireless computer 7 through the wireless local area network, and feeding the excitation signal from one end of the leaky cable 1 to be tested according to the first control instruction.

[0036] The wireless computer 7 sends a second control instruction to the tracing vehicle 5 through the wireless local area network, so that the tracing vehicle 5 moves parallel to the extending direction of the leaky cable 1 to be tested according to the second control instruction.

[0037] The spectrum analyzer 3 and the test antenna 4 are both arranged on the tracing vehicle 5, and the spectrum analyzer 3 is connected to the test antenna 4, and is used to read the real-time signal amplitude at different leaky cable positions collected by the test antenna 4 during the movement of the tracing vehicle 5, and then send the real-time signal amplitude to the wireless computer 7 through the wireless local area network.

[0038] In this embodiment, the system may include multiple devices, such as a signal source 2, a spectrum analyzer 3, a test antenna 4, a tracking vehicle 5, a wireless repeater 6, a wireless computer 7, etc. These devices can be connected to the wireless local area network constructed by the wireless repeater 6, and data transmission is performed through the wireless local area network, so that unattended operation can be achieved during the leaky cable test, thereby significantly improving the test efficiency and reducing the test time. In addition, in order to maximize the use of the wireless repeater 6, the wireless repeater 6 can be placed in the center of the leaky cable test site, so that a wireless local area network covering the entire leaky cable test site can be constructed.

[0039] Specifically, when the present application is conducting a leaky cable test, the wireless computer 7 can be wirelessly connected to the input end of the signal source 2 through a wireless local area network, and the output end of the signal source 2 can be connected to the leaky cable 1 to be tested, so that the wireless computer 7 can send a first control instruction to the signal source 2 through the wireless local area network. After the signal source 2 receives the first control instruction, it can feed an excitation signal from one end of the leaky cable 1 to be tested according to the first control instruction, so that the excitation signal is transmitted from one end to the other end of the leaky cable 1 to be tested. For example, the staff can input the working frequency band of the signal source 2 on the wireless computer 7 according to the test needs, so that when the test instruction is stimulated, the wireless computer 7 can automatically send the first control instruction containing the corresponding working frequency band to the signal source 2. After receiving the first control instruction, the signal source 2 can parse the first control instruction to obtain the corresponding working frequency band, and feed the excitation signal from one end of the leaky cable 1 to be tested according to the working frequency band.

[0040] Furthermore, after the present application feeds an excitation signal to one end of the leaky cable 1 to be tested through the signal source 2, in order to test the signal amplitude at each position of the leaky cable 1 to be tested, the present application can pre-place a tracking vehicle 5 in the leaky cable test site, and install the spectrum analyzer 3 and the test antenna 4 on the tracking vehicle 5, connect the spectrum analyzer 3 and the test antenna 4, and send a second control instruction to the tracking vehicle 5 through the wireless computer 7 and the wireless local area network, so that the tracking vehicle 5 moves parallel to the extension direction of the leaky cable 1 to be tested according to the second control instruction. In this process, the test antenna 4 collects the real-time signal amplitude at different positions of the leaky cable 1 to be tested as the tracking vehicle 5 moves. After the spectrum analyzer 3 reads the real-time signal amplitude, it can send the real-time signal amplitude to the wireless computer 7 through the wireless local area network to realize the automatic calculation and reporting of the test data. This process overcomes the problem of human factors, and the test process can achieve high consistency, thereby significantly improving the test accuracy and efficiency.

[0041] In the above embodiment, the system includes a signal source 2, a spectrum analyzer 3, a test antenna 4, a tracing vehicle 5, a wireless repeater 6 and a wireless computer 7; the present application places the wireless repeater 6 at the center of the leaky cable test site, so that a wireless local area network covering the entire leaky cable test site can be constructed; the signal source 2, the spectrum analyzer 3, the tracing vehicle 5 and the wireless computer 7 are all connected to the wireless local area network, and the input end of the signal source 2 is wirelessly connected to the wireless computer 7 through the wireless local area network, and the output end is connected to the leaky cable 1 to be tested, so that the first control instruction sent by the wireless computer 7 through the wireless local area network can be received, and an excitation signal can be fed from one end of the leaky cable 1 to be tested according to the first control instruction; the wireless computer 7 can also send an excitation signal to the tracing vehicle through the wireless local area network. 5 sends a second control instruction so that the tracing vehicle 5 moves parallel to the extension direction of the leaky cable 1 to be tested according to the second control instruction; further, the present application can also set the spectrum analyzer 3 and the test antenna 4 on the tracing vehicle 5, and connect the spectrum analyzer 3 with the test antenna 4, so that the spectrum analyzer 3 can read the real-time signal amplitude at different leaky cable positions collected by the test antenna 4 during the movement of the tracing vehicle 5, and send the real-time signal amplitude to the wireless computer 7 through the wireless local area network, and the wireless computer 7 can perform data aggregation and analysis after receiving the real-time signal amplitude; this process does not require manual operation by the user, and can achieve unattended operation during the leaky cable test, thereby significantly improving the test efficiency and reducing the test time.

[0042] In one embodiment, Figure 2 As shown, Figure 2 A system architecture diagram of an automatic leaky coaxial cable testing system with a wireless camera 8 provided in an embodiment of the present application; the system may also include a wireless camera 8.

[0043] The wireless camera 8 is also connected to the wireless local area network.

[0044] The wireless computer 7 sends a third control instruction to the wireless camera 8 via the wireless local area network, so that the wireless camera 8 monitors the test environment of the leaky cable test site according to the third control instruction.

[0045] In this embodiment, the system may further include a wireless camera 8, which may be one or more than one wireless camera 8, and one or more wireless cameras 8 may be distributed at various locations in the leaky cable test site, and the wireless camera 8 at each location is connected to the wireless local area network, so that the wireless computer 7 can send a third control instruction to the wireless cameras 8 at various locations through the wireless local area network, so that the wireless cameras 8 at various locations monitor the test environment of the leaky cable test site according to the third control instruction, thereby providing relevant basis for subsequent data analysis, and the staff can also view the current test environment through the wireless computer 7, so as to intervene in time when intervention is needed.

[0046] Of course, the present application can also pre-set the corresponding monitoring program on the wireless computer 7, and start monitoring the test environment photographed by the wireless camera 8 when the wireless computer 7 sends the third control instruction to the wireless cameras 8 in various locations or when the wireless computer 7 receives the test instruction. When encountering pre-set scenes, such as the tracking car 5 does not move, the test antenna 4 falls, thunder and rain, etc., an alarm can be sent in time to the wireless computer 7 or to the staff, so that the staff can deal with the situation in the test environment in time after receiving the alarm, so as to further improve the intelligence level of the leaky cable test.

[0047] In one embodiment, the wireless camera 8 is also used to assist the navigation of the tracking vehicle 5 according to the third control instruction.

[0048] In this embodiment, the wireless cameras 8 distributed at various locations in the leaky cable test site can not only monitor the test environment of the leaky cable test site, but also assist in navigation of the tracing vehicle 5 according to the third control instruction.

[0049] Specifically, the wireless computer 7 of the present application can send a third control instruction including monitoring the moving trajectory of the tracking car 5 to the wireless camera 8 through the wireless local area network. After receiving the third control instruction, the wireless camera 8 can report the moving trajectory of the tracking car 5 to the wireless computer 7 in real time. After receiving the moving trajectory, the wireless computer 7 compares it with the preset moving trajectory. If there is a deviation, a correction instruction can be sent to the tracking car 5 through the wireless local area network to make the tracking car 5 move according to the preset moving trajectory. If there is no deviation, the real-time moving trajectory sent by the wireless camera 8 will continue to be compared with the preset moving trajectory. This process can not only ensure that the tracking car 5 moves according to the preset moving trajectory, but also realize a fully automatic leakage cable testing process without human intervention by setting a specific program.

[0050] In one embodiment, the process of connecting the signal source 2, the spectrum analyzer 3, the tracking vehicle 5 and the wireless computer 7 to the wireless local area network may include:

[0051] The signal source 2, the spectrum analyzer 3, the tracking vehicle 5 and the wireless computer 7 are all connected to the wireless local area network through their respective configured wireless network cards.

[0052] Among them, each wireless network card is also used to provide a corresponding IP address for the wireless computer 7, so that the wireless computer 7 can send control instructions according to the corresponding IP address.

[0053] In this embodiment, when realizing the fully automatic leaky cable testing process without human intervention, the present application can connect the main testing devices, especially the signal source 2, spectrum analyzer 3, tracing car 5, wireless camera 8 and wireless computer 7 to the wireless local area network through their respective configured wireless network cards, and finally form the signal source 2, spectrum analyzer 3, tracing car 5, wireless camera 8 and wireless computer 7 connected to the same wireless local area network. The wireless computer 7 can access the signal source 2, spectrum analyzer 3, tracing car 5 and wireless camera 8 etc. through the IP addresses corresponding to the wireless network cards in the wireless local area network, and send the universal SCPI language to the signal source 2, spectrum analyzer 3 and tracing car 5 through the wireless computer 7, thereby realizing the setting of the test frequency band amplitude of each device, the sending of control instructions and the recovery of test data.

[0054] In a specific example, the present application can place the spectrum analyzer 3 on the tracing cart 5 to trace along the leaky cable bracket in sequence, the signal source 2 feeds the excitation signal at one end of the leaky cable, and the signal source 2 is connected to the public WIFI relay system, the spectrum analyzer 3 is connected to the public long-distance WIFI relay system through the LAN port, and the tracing cart 5 is also controlled through the LAN port, and the tracing cart 5 is connected to the same public long-distance WIFI relay system, and the computer equipped with a wireless access port is also connected to the same WIFI relay system, so that all devices in the wireless local area network can be remotely controlled by sending control instructions through the wireless computer 7, and especially the movement of the tracing cart 5 can be automatically controlled through the control instructions and the automatic calculation and reporting of test data can be realized.

[0055] In one embodiment, the process of the signal source 2 feeding the excitation signal from one end of the leaky cable 1 to be tested according to the first control instruction may include:

[0056] The signal source 2 determines the test frequency band used in this test according to the first control instruction, and feeds an excitation signal corresponding to the test frequency band from one end of the leaky cable 1 to be tested.

[0057] In the present embodiment, when the signal source 2 feeds an excitation signal from one end of the leaky cable 1 to be tested according to the first control instruction, it can first receive the first control instruction sent by the wireless computer 7 through the wireless local area network. The first control instruction includes the test frequency band of the signal source 2 input by the staff on the wireless computer 7 according to the test needs. After receiving the first control instruction, the signal source 2 can parse the first control instruction to obtain the corresponding test frequency band, and feed an excitation signal from one end of the leaky cable 1 to be tested according to the test frequency band.

[0058] In one embodiment, the process of the spectrum analyzer 3 reading the real-time signal amplitudes at different leaky cable positions collected by the test antenna 4 during the movement of the tracking vehicle 5 may include:

[0059] The spectrum analyzer 3 receives the fourth control instruction sent by the wireless computer 7 through the wireless local area network, and after determining the frequency band and amplitude used for this test according to the fourth control instruction, reads the real-time signal amplitude at different leaky cable positions collected by the test antenna 4 during the movement of the tracking vehicle 5 according to the frequency band and amplitude.

[0060] In this embodiment, when the spectrum analyzer 3 reads the real-time signal amplitude at different leaky cable positions, it can first receive the fourth control instruction sent by the wireless computer 7 through the wireless local area network. The fourth control instruction includes the frequency band and amplitude used by the spectrum analyzer 3 in this test. In this way, after receiving the fourth control instruction, the spectrum analyzer 3 can be initialized according to the frequency band and amplitude included in the fourth control instruction, and then read the real-time signal amplitude at different leaky cable positions collected by the test antenna 4 during the movement of the tracking vehicle 5 according to the initialization setting. In this way, after the read real-time signal amplitude is sent to the wireless computer 7, the wireless computer 7 can directly summarize or analyze the data according to the real-time signal amplitude without the need for secondary processing, thereby effectively improving the test efficiency.

[0061] In one embodiment, the tracking vehicle 5 provides power for the spectrum analyzer 3 .

[0062] The power source of the tracking vehicle 5 comes from a built-in battery or a floor-drag cable.

[0063] In this embodiment, when the tracing cart 5 is used to carry the spectrum analyzer 3 and the test antenna 4, the tracing cart 5 can also be used to provide power for the spectrum analyzer 3. The power supply can be a battery provided by the tracing cart 5 or a floor-dragging cable. This can provide sufficient power for the spectrum analyzer 3, improve test efficiency and reduce test time.

[0064] In one embodiment, the tracking vehicle 5 feeds back real-time location information to the wireless computer 7 via the wireless local area network.

[0065] In this embodiment, after receiving the second control instruction sent by the wireless computer 7 through the wireless local area network, the tracing vehicle 5 can move parallel to the extension direction of the leaky cable 1 to be tested according to the second control instruction. During this process, the tracing vehicle 5 can also feed back its real-time position information during the parallel movement to the wireless computer 7 through the wireless local area network. In this way, the wireless computer 7 can not only check the test progress of the day through the real-time position information, but also analyze it together with other test data, thereby effectively improving the accuracy of the test data.

[0066] In one embodiment, the wireless computer 7 constructs a data report based on the real-time signal amplitude sent by the spectrum analyzer 3 and the real-time position information fed back by the tracking vehicle 5 .

[0067] In this embodiment, the wireless computer 7 can not only receive the real-time signal amplitude sent by the spectrum analyzer 3, but also receive the real-time position information fed back by the tracking vehicle 5, and construct a data report based on the real-time signal amplitude and real-time position information, so that the staff can directly detect the test process intuitively based on the data report, thereby effectively improving the test efficiency.

[0068] In a specific example, the wireless computer 7 of the present application can pre-set a data report generation program, so that when the wireless computer 7 receives the real-time signal amplitude sent by the spectrum analyzer 3 and the real-time position information fed back by the tracking car 5, the data report generation program can be started to generate the corresponding data report, and the final data report is formed after the data transmission or the test is completed. Among them, the present application can form the feedback data into an Excel report-like form, and the Excel report can be set with two columns, one column is the real-time position information, and the other column is the real-time signal amplitude. This process is simple and efficient, and can improve the test accuracy. Of course, the present application can also set the data report to other forms, which can be set according to the actual situation and are not limited here.

[0069] In one embodiment, the spectrum analyzer 3 is connected to the test antenna 4 via a coaxial test cable.

[0070] In this embodiment, when the spectrum analyzer 3 is connected to the test antenna 4, a coaxial test cable may be used for connection, which is convenient for installation and can reduce wiring.
