[0001] This application relates to the technical field of device marking, and particularly to a device marking method, a terminal, and a device marking system. Background Art

[0002] When monitoring human body movements, multiple sensors are worn on the subject, and the terminal receives sensor data through wireless communication. Since the sensors are worn at different positions, the terminal processes the received data differently. As the appearances of the sensors are extremely similar, it is necessary for the staff to check and mark each sensor during wearing. The traditional method of sensor marking is to paste a paper label on each sensor, with the wearing position written on the paper label. However, the paper label is prone to falling off and wearing, resulting in the inability to identify the marked content. Moreover, the paper label needs to be manually replaced.

[0045] In one embodiment, a device marking system is provided, including the terminal in any of the above embodiments and at least one device. The schematic diagram of the device structure can be referred to Figure 3, the device includes a response unit, a display unit, and a second communication unit (not shown in the figure).

[0046] Each unit in the above terminal and device can be implemented by software, hardware, and their combination. Each of the above units can be embedded in or independent of the processor in the computer device in hardware form, or stored in the memory of the computer device in software form, so that the processor can call and execute the operations corresponding to each of the above units.

[0047] Please refer to Figure 4 , Figure 4 This is the application environment of the device marking method in an embodiment of the present application. This application environment includes a terminal and multiple devices, and the terminal communicates with the devices wirelessly. Among them, the terminal includes, but is not limited to, various personal computers, laptop computers, smart phones, and tablet computers. The device includes a sensor, and the sensor can be worn on corresponding parts of the human body, such as the head, neck, shoulders, chest, back, waist, abdomen, upper limbs, or lower limbs, to monitor human physiological data.

[0048] In one embodiment, a device marking method is provided. Please refer to Figure 5 , Figure 5 This is the flowchart of the device marking method in this embodiment. Taking this method applied to the terminal in Figure 1 , Figure 2 or Figure 4 as an example, the method includes the following steps:

[0049] Step S101, obtain at least one frame of image of the first object.

[0050] The terminal collects an image of the first object. Optionally, the first object is a human body wearing a sensor, a human body model, etc. The device is the sensor, and the sensor is provided with a response unit, a display unit, and a second communication unit. The second communication unit is coupled to the first communication unit of the terminal. Among them, the display unit includes an electronic paper label or an LED display screen. The image includes a visible light image or a thermal image.

[0051] Step S102: Identify at least one target device set to the response state in at least one frame of image, and determine the first spatial position of the at least one target device relative to the first object.

[0052] The response state can refer to the target device's activation indicator light being on or flashing at a preset frequency, or it can refer to the target device activating the heating device for heating. Whether it is the target device's activation indicator light or the heating device, the terminal can identify the response state in the image through the built-in image processing algorithm. At the same time, the terminal can also identify the human body parts in the image and use the human body part where the response state is located as the first spatial position of the target device. The first spatial position is the specific wearing position of the sensor, such as the front of the left instep, the front of the right instep, the front of the left thigh, the front of the right thigh, the front of the left calf, the front of the right calf, the dorsal side of the waist, the dorsal side of the chest, the left scapula, the right scapula, the upper arm, the lower arm, the occipital bone, the back of the left hand, the back of the right hand.

[0053] Step S103: Send a first signal to at least one target device to mark the target device, where the first signal carries information about the first spatial position.

[0054] The terminal stores a device list, which contains multiple records, and each record contains at least a device identifier. Each device identifier corresponds to a communication address. The terminal can obtain the communication address of the target device based on this device list, send the first signal to the target device corresponding to this communication address. After receiving the first signal, the target device displays the first spatial position. For example, the first spatial position is displayed in the form of a suffix after the device identifier.

[0055] In the above steps S101 to S103, the terminal can automatically identify the device to be marked, especially for marking multiple devices with the same appearance, and establish a communication link with multiple devices through wireless technology, enabling operation at a certain distance from the device, realizing automatic marking of the device to be marked, eliminating the need for manual label replacement. After long-term use, the marking will not be blurred or damaged, and can be marked repeatedly, improving the marking utilization rate, solving the problem of low device marking efficiency, and achieving the beneficial effect of efficiently marking devices.

[0056] The following embodiments will introduce how to generate the first signal.

[0057] In one embodiment, by obtaining the device identifiers of at least one target device, a first signal is generated according to the device identifiers of the at least one target device and the first spatial position. Specifically, the device identifier can be a combination of one or more of Arabic numerals, English letters, and Roman letters.

[0058] In one embodiment, by obtaining the device identifiers and grouping identifiers of at least one target device, a first signal is generated according to the device identifiers, the first spatial positions, and the grouping identifiers of the at least one target device.

[0059] In an actual application scenario, multiple sensors may be distributed on various parts of the human body based on a certain monitoring target to collect physiological data. Then, the grouping identifier can be set according to the monitoring target of the sensor. Optionally, the sensors are grouped according to the monitoring target, such as a pulse monitoring group, a body fat monitoring group, and a temperature monitoring group. Or, they are grouped according to the state of the first object, such as a human body movement state monitoring group and a human body static state monitoring group. In addition, they can also be grouped according to the production batch of the sensors. By setting the grouping identifier, it is convenient for the user to check whether the sensor is worn correctly based on this grouping identifier, reducing the probability of incorrect sensor wearing.

[0060] Further, in one embodiment, the grouping identifier of the device and the first spatial position can also be associated and stored. If the terminal determines that the detected first spatial position does not match the stored grouping identifier, the terminal will determine that the current device is worn incorrectly. For example, when performing a pulse monitoring task, it is stipulated that the sensors in the pulse monitoring group should be worn on the wrist of the human body. If the terminal detects that the current sensor is worn on other parts, the terminal will report an error and prompt the user to correct the wearing position of the sensor.

[0061] The following embodiments will further introduce the working process of the marked sensor.

[0062] In one embodiment, the terminal sends a second signal to multiple devices one by one in stages to trigger the current device to be in a response state. The terminal captures a human body image in the current stage and identifies the target device in the response state in this frame of image. Specifically, the terminal performs image processing on this frame of image, determines the region of interest in this frame of image, and determines the first spatial position of the target device relative to the first object according to the position of the region of interest. The region of interest can be a highlighted region. The terminal records the device identifier of the target device that responds to the second signal each time, and generates a first signal according to the device identifier, the grouping identifier, and the first spatial position of the target device. Among them, the terminal can send a second signal to the target device according to a preset instruction; or the terminal can send a second signal to the target device in response to an instruction input by the user. In this embodiment, the device list is displayed on the terminal operation interface, and the device list at least includes the device identifier. Optionally, the device list can also include the grouping identifier and the first spatial position. By sending the second signal one by one to highlight the device, the terminal can simply and effectively identify the target device among multiple devices with the same appearance while saving data storage space.

[0063] In one embodiment, please refer to Figure 6, a working flowchart for identifying and marking devices one by one is given. The first object wears N devices, and the terminal repeatedly executes the following steps until all N devices receive the second signal:

[0064] Step S61: The terminal receives an instruction input by the user, selects one target device from the device list, and sends a second signal to the i-th device to trigger the i-th device to be in a responsive state, where i is a natural number not exceeding N.

[0065] Step S62: The terminal acquires a human body image.

[0066] Step S63: The terminal identifies the i-th device in the current image that is in a responsive state and determines the second spatial position of the i-th device relative to the human body.

[0067] Step S64: The terminal obtains the first spatial position currently marked by the i-th device, compares the first spatial position with the second spatial position to obtain a comparison result, and increments i by 1.

[0068] In step S64, the first spatial position can be pre-stored in the terminal. If the terminal determines that the first spatial position is different from the second spatial position, the terminal edits and generates a third signal based on the device identifier, group identifier, and second spatial position, and sends the third signal to the i-th device to mark the target device, so as to automatically update the device marking information; or, generates a prompt message indicating that the i-th device is worn incorrectly. With such settings, when all devices have been marked and the user wears the sensor, it can be used to check whether the wearing position of the sensor is correct.

[0069] In one embodiment, the terminal can send a second signal to multiple devices in the same stage to trigger each device to be in a response state. The terminal captures a human body image in the current stage and identifies the target devices that are in the response state in this frame of image. Specifically, the terminal performs image processing on this frame of image, determines the region of interest in this frame of image, and determines the first spatial position of the target device relative to the first object according to the position of the region of interest, where the region of interest can be a highlighted region. The terminal obtains a pre-stored device list, which includes associated response state types and device identifiers. The terminal looks up the device identifier corresponding to the region of interest according to the device list, and generates a first signal according to the device identifier, grouping identifier, and first spatial position of the target device. When the response unit of the device is an indicator light, the indicator light colors of different devices are different, and the indicator light color is associated with the device identifier one by one; when the response unit of the device is a heating device, the heating temperatures of the heating devices of different devices are different, and the heating device temperature is associated with the device identifier one by one. Among them, the terminal can send a second signal to the target device according to a preset instruction; or, the terminal can send a second signal to the target device in response to an instruction input by the user. In this embodiment, the device list is displayed on the terminal operation interface, and the device list at least includes device identifiers. Optionally, the device list can also include grouping identifiers and first spatial positions. By sending a second signal in the same stage to highlight multiple devices and looking up the device identifier corresponding to the region of interest according to the pre-stored device list, compared with the above-mentioned scheme of highlighting and identifying devices one by one, this embodiment can perform device highlighting and identification tasks in parallel, and the marking speed is faster.

[0070] In one embodiment, please refer to Figure 7 , a working flowchart for synchronously identifying and marking devices is given, and this process includes the following steps:

[0071] Step S71, the terminal receives an instruction input by the user, selects multiple target devices in the device list, and sends a second signal to the multiple target devices to trigger the multiple target devices to be in a response state;

[0072] Step S72, the terminal captures a human body image;

[0073] Step S73, the terminal performs image recognition to determine the second spatial positions where the target devices are located;

[0074] Step S74, the terminal obtains the first spatial positions currently marked by the target devices, compares the first spatial positions with the second spatial positions, and obtains a comparison result.

[0075] In step S74, the first spatial position can be pre-stored in the terminal. If the terminal determines that the first spatial position is different from the second spatial position, the terminal edits and generates a third signal based on the device identifier, the grouping identifier, and the second spatial position, and sends the third signal to the corresponding target device to mark the target device, so as to automatically update the device marking information; or, generates a prompt message indicating that a certain target device is worn incorrectly. With such a setting, when the devices are all marked and the user wears the sensor, the wearing position of the sensor can be checked to see if it is correct.
