Description

Test methods for wearable devices

The present invention relates to a wearable device, in particular, to a testing method for the wearable device.

With the improvement of people's living standards and the use of more and more wearable devices, the spectrum resources of wireless communication are becoming more and more tight. With the inevitable trend of higher and higher data transmission rates, the wireless short-distance communication technology in the 60GHz frequency band is also attracting more and more attention, becoming one of the most potential technologies in the future wireless communication technology.

In the existing wearable devices, such as watches, for example, there are built-in antenna devices such as near-field communication (NFC) antennas, wireless network (Wi-Fi) antennas, and long-term evolution (LTE) antennas. In order to test the transmitting and receiving performance of these antennas, in some test items, such as the Error Vector Magnitude (EVM) test, the watch will be placed in the test shielding box (Shielding Box) for measurement.

The number of wearable devices to be tested in the production line can reach hundreds of units per day, which requires the tester to manually operate the wearable device, put the wearable device in the test mode, and then place the wearable device on the jig of the test mask box. Then, after confirming that the wearable device is connected to the computer with over-the-air technology, the test mask box is closed, and the tester manually operates the computer to allow the wearable device to perform related measurement operations inside the test mask box.

In the current testing process for wearable devices, no matter whether it is putting the wearable device in the test state or making the wearable device perform related measurement operations inside the test mask box, it must be completed manually by the tester. As a result, the test steps are too complicated and the test time is too long, making it difficult to quickly complete the wearable device test operation.

In view of this, how to provide a test method for wearable devices, which can not only improve the test efficiency of test stations for wearable devices, but also save test time and reduce the fatigue of production line testers, is an urgent problem to be solved in the industry.

An embodiment of the present invention provides a testing method for a wearable device, which can solve the problem that in the existing testing process of a wearable device, whether it is putting the wearable device in a test state or making the wearable device perform related measurement operations inside the test mask box, it must be completed manually by a tester, resulting in too complicated testing steps and too long testing time, making it difficult to quickly complete the testing operation of the wearable device.

When the incident wave is incident on the prosthesis module and generates a reflected wave, the wearable device that receives the reflected wave will actively connect to the computer through OTA technology and perform measurement operations.

In the test method of the wearable device of the present invention, before the step of closing the test mask box, the following steps are further included:

In the test method of the wearable device of the present invention, the value of the reflected wave is within a range of 75%-85% of the value of the incident wave.

In the test method of the wearable device of the present invention, the value of the reflected wave is 80% of the value of the incident wave.

In the testing method of the wearable device of the present invention, the wearable device has a millimeter wave transceiver, and the millimeter wave transceiver is used for transmitting incident waves and receiving reflected waves.

In the testing method of the wearable device of the present invention, the wearable device continuously emits incident waves before connecting with the computer for measurement.

In the testing method of the wearable device of the present invention, the mask box for testing has a jig, and the prosthesis module is a part of the jig.

In the test method of the wearable device of the present invention, the test mask box has a telescopic oil pressure tube, and the telescopic oil pressure tube is used to control the entry and exit of the jig, so that the test mask box is in an open state or a closed state.

In the testing method of the wearable device of the present invention, the wearable device is equipped with a plurality of antenna devices, and the plurality of antenna devices include short-range wireless communication antennas, wireless network antennas, and long-term evolution antennas.

In the embodiment of the present invention, since the wearable device can actively transmit the incident wave and receive the reflected wave through the automatic test mode for identification, and the wearable device can further actively connect to the computer through the over-the-air technology for measurement under certain conditions, the application can not only effectively improve the test speed of individual wearable devices, but also improve the overall test efficiency of the test station, thereby further reducing the waiting time and operational fatigue of production line testers.

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Fig. 1 is a step diagram of the test method of the wearable device of the present application, Fig. 3 is a schematic diagram of the test mask box of the test method of the wearable device of the present application in an open state, and Fig. 4 is a schematic diagram of the test mask box of the test method of the wearable device of the present application in a closed state. Please refer to FIG. 1, FIG. 3 and FIG. 4 at the same time. A test method for a wearable device 400 of the present application includes the following steps:

Step 110: providing a computer 200 with over-the-air technology;

Step 120: Provide a test mask box 300; the test mask box 300 is connected to the computer 200, and the test mask box 300 has a prosthetic module 310;

Step 130: placing a wearable device 400 on the prosthesis module 310; and

Step 140: Close the mask box 300 for testing.

Wherein, the wearable device 400 of the present application has an automatic test mode without being pressed and operated by a tester multiple times. The automatic test mode controls the wearable device 400 to actively emit an incident wave I. When the incident wave I enters the prosthetic module 310 and generates a reflected wave R, the wearable device 400 that receives the reflected wave R will actively connect to the computer 200 through OTA technology and perform measurement operations according to the preset instructions of the automatic test mode. In addition, the connection methods between the test mask box 300 and the computer 200 may include wired connection methods such as physical network and universal port, or wireless connection methods such as wireless network and radio frequency signal, but it is not limited thereto.

FIG. 2 is a step diagram of identifying whether the value of the reflected wave is at a specific value by the wearable device in the test method of the wearable device of the present application. As shown in FIG. 2 , in the testing method of the wearable device 400 of the present application, before performing the step of closing the test mask box 300 in step 140, the following steps are further included:

Step 131: Identify whether a value of the reflected wave R is at a specific value by the wearable device 400;

Step 132: If yes, the wearable device 400 transmits a signal to inform the computer 200 that the measurement can be performed;

Step 133: If not, the wearable device 400 continues to emit the incident wave I.

In an embodiment, the value of the reflected wave R ranges from 75% to 85% of the value of the incident wave I. In a preferred embodiment, the specific value of the value of the reflected wave R is 80% of the value of the incident wave I.

In detail, because the test of the wearable device 400 is to simulate whether the various wavelengths emitted by the wearable device 400 can meet the relevant requirements when the wearable device 400 is worn on the human body, and whether the data signal can be transmitted stably without causing harm to the human body, the prosthesis module 310 placed on the wearable device 400 is used to simulate the human body, and it has a dielectric material that simulates the human wrist.

FIG. 5 is a schematic diagram of the wearable device of the present application placed on the prosthesis module. As shown in FIG. 5 , when the wearable device 400 is placed on the prosthesis module 310 and the wearable device 400 actively emits the incident wave I, so that the emitted incident wave I touches the prosthesis module 310, because the air medium through which the incident wave I originally passed is transformed into a dielectric material simulated by the human wrist, according to Snell's Law, a part of the reflected wave R will be generated. Among them, because most of the substances in the human body are water (water has a dielectric constant of about 80 at 20 degrees Celsius and 1 atmosphere pressure), the dielectric constant is very high, and the prosthesis module 310 has a dielectric material that simulates the wrist of the human body, so it can be defined that when the value of the reflected wave R is between 75% and 85% of the value of the incident wave I, the automatic test mode can be judged to have placed the wearable device 400 on the prosthesis module 310, so that the automatic test mode can instruct the wearable device 400 to launch The signal informs the computer 200 that the subsequent measurement operation can be performed.

On the contrary, if the wearable device 400 recognizes that the value of the reflected wave R does not fall between 75%~85% of the value of the incident wave I, the automatic test mode will determine that the wearable device 400 is not placed on the prosthesis module 310 . At this time, the wearable device 400 is not ready for subsequent measurement operations, and the automatic test mode instructs the wearable device 400 to continuously emit the incident wave I.

Preferably, as shown in FIG. 5 , a millimeter wave transceiver 410 is built in the wearable device 400 . The millimeter wave transceiver 410 is used to transmit the incident wave I and receive the reflected wave R, but it is not limited thereto. In other words, in other embodiments, the wearable device 400 can also transmit the incident wave I and receive the reflected wave R through other types of wavelength transceivers. In addition, the wearable device 400 can also be equipped with multiple antenna devices. The multiple antenna devices include Near Field Communication (NFC) antennas, Wireless Network (Wi-Fi) antennas, and Long Term Evolution (LTE) antennas, etc., but it is not limited thereto.

Since the automatic test mode of the wearable device 400 of the present application can control the wearable device 400 to actively emit the incident wave I without requiring the tester to perform multiple pressing operations, the wearable device 400 will actively and continuously emit the incident wave I before connecting with the computer 200 for measurement, and will not stop emitting the incident wave I until the wearable device 400 recognizes that the value of the reflected wave R is within the range of the aforementioned specific value and sends a signal to notify the computer 200 that the measurement can be performed. That is to say, through the automatic test mode carried by the wearable device 400, the tester can test the wearable device without pressing and operating the wearable device 400 multiple times, which will make the wearable device 400 have no traces of artificial use during the testing and packaging stages, and allow the user to see the complete factory default state when the wearable device 400 is purchased.

As shown in FIG. 3 and FIG. 5 , in this application, the mask box 300 for testing has a jig 320 , and the prosthesis module 310 is a part of the jig 320 and is located above the jig 320 . Wherein, because the wearable device 400 is placed on the prosthesis module 310 and is in contact with the prosthesis module 310, the incident wave I actively emitted by the wearable device 400 will partially penetrate the prosthesis module 310 and then be reflected by the jig 320, resulting in the value of the reflected wave R reflected by the jig 320 being extremely small, and not between 75% and 85% of the value of the incident wave I. That is to say, the value of the reflected wave R reflected by the jig 320 will be identified as not falling within a specific value range, and the reflected wave R reflected by the jig 320 will not affect the identification of the wearable device 400 .

Please refer to FIG. 3 again. In this application, the test mask box 300 has a telescopic oil pressure tube 330 . The extension or retraction of the telescopic oil pressure tube 330 can be used to control the entry and exit of the jig 320 , so that the test mask box 300 is in an open state or a closed state. It should be noted that, in this application, the test mask box 300 is a shield body made of conductive or magnetically conductive material, which is a metal body for suppressing radiation interference, and can provide a non-interference test environment for the wireless communication device to be tested. Therefore, when the test mask box 300 is in a closed state, it means that the wearable device 400 is in a test environment that will not be disturbed.

As shown in FIG. 3 and FIG. 4 , in a preferred embodiment, the computer 200 has a display screen 210 . The display screen 210 is used to display the tester's operation instruction, so that the tester can manually open or close the test mask box 300 according to the operation instruction on the display screen 210 . That is to say, in this application, the tester only manually operates actions such as placing the wearable device 400 on the prosthesis module 310 , closing the testing mask box 300 , and opening the testing mask box 300 , eliminating the need for multiple operations such as pressing the wearable device 400 , operating the computer 200 and connecting the wearable device 400 .

In summary, in the wearable device testing method of the present application, since the wearable device 400 can actively transmit the incident wave I and receive the reflected wave R through the automatic test mode for identification, and the wearable device 400 can actively connect to the computer 200 through the over-the-air technology for measurement after identifying the reflected wave R and meet certain conditions. In addition to the test speed of the wearable device 400 , the overall test efficiency of the test station of the wearable device 400 can be improved, thereby further reducing the waiting time and operational fatigue of production line testers.

The above-mentioned embodiments are only to illustrate the technical ideas and characteristics of the present invention, and its purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. It should not be used to limit the patent scope of the present invention, that is, all equal changes or modifications made according to the spirit disclosed in the present invention should still be covered within the patent scope of the present invention.
