Description

Technical Field

[0001] The present invention relates to the field of outdoor detection technology, and in particular to an outdoor activity monitoring method and a portable outdoor monitoring device. Background Art

[0002] Studies have shown that appropriate outdoor exercise can allow humans to get the right amount of ultraviolet radiation, especially for the elderly and children. Appropriate sun exposure not only helps prevent myopia, but also promotes calcium synthesis in the human body, which is of great benefit to human health. Of course, long-term sun exposure is prone to ultraviolet damage. As the comfort of the indoor environment has improved, fewer and fewer people pay attention to sun exposure. Most office workers rarely have the opportunity to sunbathe. Children and teenagers also cannot get the right amount of outdoor activities because they stay in the classroom for a long time. A wearable device has emerged to monitor the status of human outdoor activities, thereby helping people understand their outdoor activities and also playing a certain supervisory role in people's outdoor activities.

[0003] There are several ways for this type of wearable device to detect outdoor conditions: (1) using ultraviolet light sensor + visible light sensor detection. The disadvantage of this method is that the average price of ultraviolet light sensor is about 30 yuan, and the affordable version is also 5 to 10 yuan; (2) using light-sensitive + color-sensitive sensor detection. The disadvantage of this method is that the color-sensitive sensor is generally more expensive than the ultraviolet sensor, and the affordable version is also priced at more than 10 yuan in bulk; (3) using a single brightness sensor detection method. The disadvantage of this method is that it cannot accurately distinguish between indoor and outdoor. For example, when it is close to the indoor light source, it will have a similar result to the outdoor brightness detection. In addition to the above sensor detection, some wearable devices are also equipped with GPS assisted positioning to detect the user's indoor and outdoor positions, but the stability of GPS positioning equipment needs to be verified. For example, when the location information on the roof is the same as that inside the building, and when the user is in a sunny high-rise building where he can receive better sunlight, the GPS positioning result is indoors, resulting in information contradictions, which is not conducive to the statistics and processing of the overall information. In addition, the price of the GPS module is not low and the power consumption is high.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] An outdoor activity monitoring method according to an embodiment of the present invention, as Figure 1 shown, is applied to a portable outdoor monitoring device, and the method includes the following steps:

[0039] Step S10: Measure the brightness of the spectrum to be detected according to a preset measurement frequency to obtain an array of brightness values .

[0040] The portable outdoor monitoring device according to the embodiment of the present invention is provided with a plurality of photosensitive sensors. In this step represents the number of photosensitive sensors provided in the portable outdoor monitoring device. The reason why the photosensitive sensor is selected in the present invention is that compared with ultraviolet sensors and color-sensitive sensors, the cost of the photosensitive sensor is lower. On average, one photosensitive sensor only costs 0.1 to 0.3 yuan, which can reduce the cost of the overall portable outdoor monitoring device.

[0041] The array of brightness values obtained in this step can be understood as a 1*m-dimensional vector for subsequent operations.

[0042] Step S20: Calculate the brightness values corresponding to different wavelengths in the spectrum to be detected according to the pre-determined spectral segment intensity information and the array of brightness values , .

[0043] In this step represents that the spectrum to be detected is divided into different wavelengths.

[0044] Since the photosensitive sensor can only detect the total brightness value of light and cannot detect the brightness value of light in a specific band, in this step, the brightness values corresponding to different wavelengths in the spectrum to be detected are further calculated through the pre-determined spectral segment intensity information 。

[0045] Step S30: Generate monitoring labels according to the empirical parameters corresponding to different wavelengths and the brightness values preset. Generate monitoring labels.

[0046] The brightness values corresponding to different wavelengths in the spectrum to be detected are obtained through Step S20. Since the light intensity of sunlight is different at different time periods, and the intensity of light with different wavelengths also varies at each time period, and different regions and different weather conditions will all have an impact, it is very necessary to calculate the brightness values corresponding to different wavelengths in the spectrum to be detected, which can more intuitively express the outdoor lighting situation. In addition, the empirical parameters corresponding to different wavelengths preset in this step may include the brightness values and brightness ratios corresponding to different wavelengths, which are used for the generation of monitoring labels. According to the detection time and the calculated brightness values Generate monitoring labels containing a plurality of pieces of information helpful for information analysis.

[0047] The generation frequency of the monitoring labels can be generated corresponding to the preset measurement frequency, or a monitoring label can be generated according to the mutation of the brightness value (indicating that the user enters the indoor from the outdoor or exits from the indoor to the outdoor) and the duration. After the data obtained by this step is informatized, Step S40 is executed.

[0048] Step S40: Statistically count the monitoring labels within the monitoring period according to the preset monitoring period, and correspondingly generate outdoor activity information.

[0049] In this embodiment, the monitoring period is set to one day, one week, one month, etc. The outdoor activity information corresponding to the preset monitoring period is statistically counted through the information of the monitoring labels.

[0050] The outdoor activity information obtained in this step not only includes the total duration of outdoor activities, but also can statistically count the duration of different light intensity intervals according to the brightness value, which is convenient for users to understand whether the user's outdoor activities are appropriate and whether there is a risk of sunburn.

[0051] Specifically, as Figure 2 shown, the method for measuring the spectral segment intensity information in the embodiment of the present invention includes:

[0052] Step S501: Place the portable outdoor monitoring device equipped with photosensitive sensors into a dark box.

[0053] To ensure the accuracy of the spectral segment intensity information, the dark box in this embodiment is provided with a partition layer, and laser light sources are placed side by side in the partition layer of the dark box, and a light homogenizing film is laid on the inner wall of the dark box to make the inside of the dark box reach a light environment without shadows, without direction, and with consistent brightness.

[0054] Step S502: Place the standard spectral illuminometer in the dark box to make its illuminance consistent with that of the portable outdoor monitoring device.

[0055] The order of steps S501 and S502 in this embodiment can be adjusted. Just place both the portable outdoor monitoring device and the standard spectral illuminometer in the dark box, preferably arranged side by side, so that the illuminances of the portable outdoor monitoring device and the standard spectral illuminometer are kept consistent or as consistent as possible.

[0056] Step S503: Turn on laser light sources in sequence. Each photosensitive sensor obtains the corresponding brightness detection value, and the standard spectral illuminometer obtains the corresponding brightness standard value respectively.

[0057] In this step the wavelengths of the laser lights emitted by the laser light sources are respectively ; the wavelengths of the laser lights emitted by the

[0058] laser light sources are not equal. Preferably, in this step, the laser light sources are turned on in the order of gradually increasing or decreasing wavelength values. More preferably, in this embodiment, the laser light sources are arranged in the order of gradually increasing or decreasing wavelength values when arranged. For example, when the first laser light source is turned on, its wavelength is , and each of the photosensitive sensors obtains the brightness detection value corresponding to the wavelength as

[0059] Step S504: Generate a response sensitivity matrix as the spectral segment intensity information; the response sensitivity matrix is:

[0060] .

[0061] The response sensitivity matrix is composed of response sensitivity values. Step S504 is specifically: by dividing each brightness detection value by the brightness standard value at the corresponding wavelength, the response sensitivity values in the response sensitivity matrix are obtained.

[0062] The brightness standard values altogether include ones. When calculating the corresponding response sensitivity for , the measured corresponding brightness standard value is L1. Then, by dividing by L1, the corresponding response sensitivity is calculated as ; when calculating When the corresponding response sensitivity is measured and the corresponding brightness standard value is L2, then by Dividing by L2, the corresponding response sensitivity is calculated as , and so on, to obtain the response sensitivity matrix .

[0063] Specifically, as Figure 3 shown, based on the previous embodiment of the present invention, step S20: According to the pre-determined spectral segment intensity information and the brightness value array , calculate the brightness values corresponding to different wavelengths in the spectrum to be detected , including:

[0064] Step S201: Calculate the inverse matrix of the response sensitivity matrix .

[0065] When selecting the number of photosensitive sensors in the embodiment of the present invention, it should be avoided that within the error range, the rank of the response sensitivity matrix is , that is, the response curves of the photosensitive sensors are linearly independent, and the response sensitivity matrix is a row full-rank matrix. When the unknown spectrum (spectrum to be detected) irradiates the photosensitive sensors, the brightness values measured by each photosensitive sensor are respectively , and these brightness values are the sum of the brightnesses of each wavelength included in the spectrum to be detected. Therefore, the brightness values corresponding to different wavelengths satisfy: , so this step needs to first calculate the inverse matrix of the response sensitivity matrix , and then execute step S202.

[0066] If , the inverse matrix is not a standard inverse matrix, but the right inverse matrix of the response sensitivity matrix , and the specific calculation method is not elaborated here.

[0067] Step S202: Calculate the brightness value through the inverse matrix and the brightness value array .

[0068] Among them, the brightness value = .

[0069] Specifically, on the basis of having the above realization of generating outdoor activity information, eye protection suggestions can also be generated according to the preset eye protection prompt threshold and monitoring label. For example, the brightness value ​​If there are values exceeding the set threshold in [the data], it indicates that the current light is too strong, which may cause damage to the human eyes. The user can be prompted to protect their eyes in time through a sound warning. The push method of eye protection suggestions can also be achieved by wireless communication between the portable outdoor monitoring device and the smart terminal. The smart terminal receives the prompt information, or through vibration or light flashing, all of which can achieve the design purpose of the present invention.

[0070] The embodiment of the present invention also includes a portable outdoor monitoring device, such as Figure 4 shown, the portable outdoor monitoring device 10 includes: a measurement module 101 and an information processing module 102, and the measurement module 101 is connected to the information processing module 102;

[0071] The measurement module 101 includes a plurality of photosensitive sensors; the measurement module 101 is used to measure the brightness of the spectrum to be detected according to a preset measurement frequency to obtain a brightness value array ;

[0072] The information processing module 102 is used to calculate the brightness values corresponding to different wavelengths in the spectrum to be detected according to the pre-determined spectral segment intensity information and the brightness value array ; ; It is represented that the spectrum to be detected is divided into a plurality of different wavelengths; and, according to the empirical parameters corresponding to the preset different wavelengths and the brightness values generate a monitoring label; and, count the monitoring labels within the monitoring period according to the preset monitoring period and correspondingly generate outdoor activity information.

[0073] The above process of generating the monitoring label and the user activity information can be understood in combination with the embodiments of the foregoing outdoor activity monitoring method, and will not be elaborated here.

[0074] Specifically, the measurement module 101 in the embodiment of the present invention includes at least three photosensitive sensors and is provided with at least three light measurement windows; a first photosensitive sensor is installed in the first light measurement window, and the first light measurement window is a full-spectrum and fully transparent light measurement window; a second photosensitive sensor is installed in the second light measurement window, and an ultraviolet filter film is provided on the second light measurement window; a third photosensitive sensor is installed in the third light measurement window, and an infrared light-transmitting film is provided on the third light measurement window. A photosensitive sensor is provided under each independent light measurement window to obtain a brightness value. In this embodiment, more light measurement windows and photosensitive sensors can also be set, and more detailed light-transmitting films can be selected to improve the wavelength segmentation granularity.

[0075] Specifically, the measurement module 101 in the embodiments of the present invention includes at least one photosensitive sensor and a liquid crystal screen located above the photosensitive sensor; at least three light measurement windows are provided on the liquid crystal screen, the first light measurement window is a full-spectrum fully transmissive light measurement window, an ultraviolet filter film is attached to the second light measurement window, and an infrared transmissive film is attached to the third light measurement window; when the liquid crystal screen is not powered on, light can penetrate through all three light measurement windows, and when the liquid crystal screen is powered on, light can optionally penetrate through the three light measurement windows.

[0076] The above two embodiments set multiple light measurement windows and filter / transmissive films to achieve wavelength segmentation, which is similar to the function of using different wavelength bands of a plurality of laser light sources in the foregoing method embodiments, but the spectra obtained in these two ways have less overlap, are applicable to situations with low accuracy requirements, and can achieve simple calibration.

[0077] Specifically, the portable outdoor monitoring device in the embodiments of the present invention further includes a wearing component, and the measurement module 101 and the information processing module 102 are installed on the wearing component; the portable outdoor monitoring device is fixed at a corresponding position through the wearing component.

[0078] Since the portable outdoor monitoring device in the embodiments of the present invention has a simple composition, it can be completely designed as a small and portable product, which can be worn on the wrist as a watch or fixed to the user's clothes or backpack by means of a pin, magnetic attraction, magic tape, etc.

[0079] The embodiments of the present invention do not make specific limitations on the appearance of the portable outdoor monitoring device, which can be combined with cartoon images, not only achieving the monitoring purpose of the present invention, but also playing a certain decorative role. The embodiments of the present invention can also combine the monitoring functions realized by the monitoring device with existing wearable devices to make the functions of existing wearable devices more diverse.

Then, monitoring labels are generated based on the empirical parameters corresponding to different wavelengths and the brightness values preset, and finally, the monitoring labels within the monitoring period are statistically counted according to the preset monitoring period, and the outdoor activity information is generated correspondingly. The present invention can measure the light intensity in real time through an inexpensive photosensitive sensor, calculate the brightness values corresponding to different wavelengths through the pre-determined spectral segmentation intensity information, and then accurately count the user's outdoor activities through the monitoring labels, playing a role of supervision and suggestion for the user's outdoor activities; the portable outdoor monitoring device is not only low in cost, but also has very low power consumption and has high practical value.

However, it should be understood that this specific description should not be construed as a limitation on the essence and scope of the present invention. Various modifications made by those of ordinary skill in the art to the above embodiments after reading this specification all fall within the scope protected by the present invention.
