[0034] To make the objectives, technical solutions, and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention with reference to the accompanying drawings in the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

[0035] In the test of the recorder of the capsule endoscope system, it is necessary to first test the single antenna of the recorder. Only after the single antenna test is qualified can the recorder be assembled as a whole. Due to the sensitivity of radio frequency signals, during the assembly process, due to the differences in assembly processes and the operating techniques of personnel, it is inevitable that there are differences in the assembled recorder as a whole. Although the prior art tests the recorder as a whole, the signal strength of the recorder and the consistency of the communication distance with the capsule cannot be guaranteed.

[0036] Therefore, the embodiment of the present invention proposes a test device for the recorder of the capsule endoscope system to solve the problem of low test accuracy of the recorder in the application environment of the capsule endoscope system. The following is an introduction in combination with Figures 1 to 3 :

[0037] The test device for the recorder of the capsule endoscope system includes: a capsule endoscope 1, a mounting table 2, and a console 3;

[0038] The capsule endoscope 1 is used to capture real-time dynamic images;

[0039] The mounting table 2 is arranged on one side of the capsule endoscope 1 and is used to set the recorder 4. The mounting table 2 can move relative to the capsule endoscope 1;

[0040] The console 3 is used to monitor the communication signal strength from the recorder 4 to the capsule endoscope 1 and the real-time dynamic images captured by the capsule endoscope 1 received by the recorder 4.

[0041] In the test device for the recorder of the capsule endoscope system in the embodiment of the present invention, by setting a mounting table that can move relative to the test table on one side of the capsule endoscope, the movement of the recorder relative to the capsule endoscope is realized. Thus, the device in the embodiment of the present invention can obtain the optimal communication distance between the recorder and the capsule endoscope and the corresponding signal strength.

[0042] It should be noted that the console can be a mobile phone, a tablet computer, or a computer.

[0043] In at least one embodiment of the present invention, as Figure 2 shown, the mounting table 2 is arranged on the slide rail 9 and the mounting table 2 can move relative to the capsule endoscope 1 along the slide rail 9.

[0044] In the test device for the recorder of the capsule endoscope system in the embodiment of the present invention, by setting the slide rail, the stable and uniform sliding of the mounting table relative to the test table is realized, reducing the error caused by the jitter during the movement of the tester, and achieving a better test effect.

[0045] In at least one embodiment of the present invention, as Figure 2 shown, the slide rail 9 is provided with scales.

[0046] In the recorder test device of the capsule endoscope system according to the embodiment of the present invention, through the slide rail 9 provided with scales, the direct monitoring of the communication distance between the recorder and the capsule endoscope can be realized without sensors or other signal acquisition devices. The recorder can slide left and right to arbitrarily adjust the communication distance with the capsule, which is convenient for formulating design parameters.

[0047] In at least one embodiment of the present invention, the controller 3 can collect the distance between the mounting table 2 and the capsule endoscope 1 through a sensor, and combine the monitored communication signal strength from the recorder 4 to the capsule endoscope 1 to draw a distance-intensity curve, which is convenient for testers to directly obtain the optimal communication distance.

[0048] In at least one embodiment of the present invention, the capsule endoscope 1 is arranged on the base 6, the base 6 is arranged in the dark box 5, and an activator 7 is also arranged in the dark box 5. The activator 7 is used to activate the capsule endoscope to make the capsule endoscope in a working state.

[0049] It should be noted that the activator is a strong light source, which can turn on the capsule endoscope and make the capsule endoscope work. The number of configured activator light sources is selected according to the needs of the capsule endoscope. A normal capsule can be activated and turned on only when the illuminance is above 3000 LX. In the embodiment of the present invention, 2 activator light sources are selected and configured.

[0050] In at least one embodiment of the present invention, a stopwatch 8 is arranged in the dark box 5, and the stopwatch 8 is arranged within the shooting field of view of the capsule endoscope 1.

[0051] It should be noted that the stopwatch is installed on the top of the dark box.

[0052] In the recorder test device of the capsule endoscope system according to the embodiment of the present invention, through the stopwatch arranged in the dark box, the real-time dynamic image situation of the capsule can be viewed at the console. According to the stopwatch reading pictures, it can be judged whether the capsule endoscope system is in a normal working state and whether the communication distance between the capsule endoscope and the recorder is within a suitable range, avoiding the phenomenon of unsmooth or stuck image transmission due to the capsule endoscope being too far away from the recorder without a reference object.

[0053] In at least one embodiment of the present invention, the dark box 5 includes a first power supply circuit and a second power supply circuit. The first power supply circuit is used to supply power to the activator 7, and the second power supply circuit is used to provide a DC power supply to the capsule endoscope 1.

[0054] It should be noted that the first power supply circuit includes a switch S1 connected in series with the activator and a strong light source power supply for the activator, and the second power supply circuit includes an external capsule continuous power supply connected in series with the base 6 and a switch S2, wherein the external capsule continuous power supply is 3V.

[0055] In the capsule endoscope system recorder testing device according to the embodiment of the present invention, by providing a DC power supply for the capsule endoscope 4, it avoids the trouble of frequently replacing the capsule battery due to power exhaustion during the testing process when the traditional capsule uses a button battery for power supply.

[0056] As Figure 2 shown, the working principle of the device according to the embodiment of the present invention is as follows: Close S2 to power on the capsule; then close S1. At this time, the two light sources of the activator are turned on, and at the same time the capsule is activated and lit. After the capsule is lit, disconnect S1. Connect the capsule to the recorder system through the mobile phone APP control program. At this time, on the mobile phone APP program control terminal, the stopwatch image video captured by the capsule in real time can be seen. Move the recorder left and right on the slide rail, observe the change of the communication signal strength RSSl from the recorder to the capsule on the mobile phone APP debugging terminal, and at the same time observe whether the stopwatch image video captured by the capsule is smooth, and record the best distance from the recorder to the capsule and the signal RSSI.

[0057] As Figure 3 shown, it is a schematic diagram of the communication principle of the device according to the embodiment of the present invention, including: The capsule endoscope receives the instruction of the recorder, collects the image data of the patient's stomach and sends it to the recorder for storage. At the same time, the recorder forwards it to the loaded APP mobile intelligent terminal (such as a mobile phone / tablet computer, etc.) through Bluetooth.

[0058] The testing device according to the embodiment of the present invention can be used for formulating the communication distance standard between the capsule endoscope and the recorder in an air environment; it can be used to test the signal strength and the consistency of the signal strength of multiple recorders; according to the consistency of the signal strength, the quality of the recorder can be judged, so as to test whether the antenna of the recorder is assembled well and whether there is a problem with the antenna body.

[0059] Next, the capsule endoscope system recorder testing method provided by the present invention will be described. The capsule endoscope system recorder testing method described below uses any one of the capsule endoscope system recorder testing devices in the above embodiments to debug the radio frequency parameters of the recorder. As Figure 4 shown, it includes:

[0060] S401. After the capsule endoscope works normally, move the installation table away from the capsule endoscope, and monitor in real time through the console the communication signal strength from the recorder to the capsule endoscope and the distance between the recorder and the capsule endoscope;

[0061] S402. Obtain the maximum communication distance from the recorder to the capsule endoscope and the communication signal strength at the maximum communication distance, and debug the radio frequency parameters of the recorder according to the communication signal strength at the maximum communication distance.

[0062] In at least one embodiment of the present invention, before the capsule endoscope works normally, it further includes:

[0063] S501. Power the capsule endoscope with a DC power supply;

[0064] S502. Power the activator. After the capsule endoscope is activated and lit, power off the activator;

[0065] S503. The console controls the capsule endoscope to start working normally.

[0066] In the capsule endoscope system recorder test device in the embodiment of the present invention, by providing a DC power supply for the capsule endoscope, it avoids the trouble of frequently replacing the battery due to power exhaustion during the test when the traditional capsule endoscope uses a button battery-like power supply.

[0067] In at least one embodiment of the present invention, for the console to monitor in real time the communication signal strength from the recorder to the capsule endoscope and the distance between the mounting table and the test table, it further includes:

[0068] The console monitors the dynamic images captured by the capsule endoscope in real time, and judges whether the communication distance between the capsule endoscope and the recorder is within a suitable range according to the smoothness of the dynamic images, avoiding the phenomenon that the image transmission is not smooth or stuck because the capsule endoscope is too far away from the recorder without a reference object.

[0069] Preferably, the real-time dynamic image is an image of the real-time reading of a stopwatch. The working state of the capsule endoscope can be monitored in time according to the change of the stopwatch reading.

[0070] In the capsule endoscope system recorder test method in the embodiment of the present invention, by setting a stopwatch in the dark box, the real-time dynamic image situation of the capsule can be viewed at the console, and it can be judged whether the communication distance between the capsule endoscope and the recorder is within a suitable range according to the stopwatch reading picture, avoiding the phenomenon that the image transmission is not smooth or stuck because the capsule endoscope is too far away from the recorder without a reference object.

[0071] The device embodiments described above are merely illustrative.

Some or all of the modules can be selected according to actual needs to achieve the purpose of the solution of this embodiment. A person of ordinary skill in the art can understand and implement it without creative efforts.

[0072] Through the description of the above embodiments, those skilled in the art can clearly understand that each embodiment can be implemented by means of software plus a necessary general hardware platform, and of course, it can also be implemented by hardware.
