DETAILED DESCRIPTION

[0056] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0057] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that such use is interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the term "including" and its variants are to be interpreted as open-ended terms meaning "including but not limited to".

[0058] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0059] As mentioned above, when different types of glasses are used together, soldiers are required to carry their own glasses or each person carries a type of glasses and uses them cross-wise in teams. This method seriously increases the weight of soldiers or reduces the efficiency of soldiers using different glasses. In order to solve the above problems, the present application provides a multifunctional head-mounted device. Figure 1 , Figure 2 , Figure 3As shown, a multifunctional head-mounted device includes: a main pair of glasses 100, a first interface 200, a first accessory, a second interface and a second accessory; one first interface 200 is provided, and the first interface 200 is provided on the main pair of glasses 100, and multiple first accessories are provided, one of which is connected to the first interface 200, and the first accessory and the first interface 200 are detachably connected. Multiple second interfaces are provided, and multiple second accessories are provided, and the second interface and the second accessory are detachably connected in a one-to-one correspondence. In the present application, by providing the first interface 200 and the second interface, the first accessory and the second accessory can be freely selected according to needs, so as to achieve the effect of using multiple glasses at the same time, reduce the weight of the soldiers as much as possible, increase the efficiency of using the glasses, and improve the convenience in action.

[0060] Specifically, the main glasses 100 are one of low-light low-light sights, image intensifier low-light sights, infrared sights, TV white light sights, and multi-spectral sights. The first accessories include: an infrared detection module, a distance measurement module, a multi-spectral module, and a TV aiming module. The first accessories are selected according to the type of the main glasses 100. When the main glasses 100 are low-light low-light sights, the first accessories can be any one of an infrared detection module, a distance measurement module, a multi-spectral module, and a TV aiming module, and any one of an infrared detection module, a distance measurement module, a multi-spectral module, and a TV aiming module can be installed on the first interface 200. For example, when an infrared detection module is externally connected to the main glasses 100 through the first interface 200 and a battery power module is externally connected through the second interface, the infrared information detected by the infrared detection module and the power information of the battery power module can be observed through the eyepiece in the main glasses 100. The main glasses 100 can process and process the information of the infrared detection module, such as selecting and tracking a specific target observed by the infrared detection module. The first accessories of this application are complete in variety. In the face of different training tasks and observation conditions, the best observation effect can be achieved by reasonably selecting the first accessories.

[0061] Furthermore, the first interface 200 may be fixed to the main glasses 100 by sharing one or more components with the main glasses 100 or by riveting with screws / bolts or welding.

[0062] Furthermore, the main glasses 100 are binocular binocular head-mounted glasses. When the main glasses 100 use low-light and low-light scopes, they are composed of a left lens barrel 110, a bracket 140, a right lens barrel 120, and an eye mask 130. The first interface 200 is provided on the left lens barrel 110, and the first accessory is connected to the main glasses 100 through the first interface 200 on the left lens barrel 110 to achieve electrical functional interconnection. Furthermore, the number of first interfaces 200 provided on the main glasses 100 is not limited to one or two, and a reasonable spatial arrangement and number of settings should be performed according to actual usage requirements.

[0063] Furthermore, the electrical interface 220 of the first interface 200 and the electrical interface 510 of the first accessory are paired. Figure 4 As shown, the first interface 200 is composed of an electrical interface 220 and a mechanical interface 210. In this embodiment, the electrical interface 220 is composed of electronic components, such as a PCB board, a pin, a spring pin, a first contact, etc. Furthermore, the number and size of the pins and contacts should be determined according to actual usage. Figure 6 As shown, a plate and a second contact corresponding to the electrical interface 220 are provided on the electrical interface 510 of the first accessory, and the electrical interface 220 is connected to the electrical interface 510 of the first accessory, so that the first interface 200 and the first accessory can achieve electrical and signal connection. The mechanical interface 210 is composed of a base 211, a pressure plate 212, a handle 213, etc. The base 211 is fixed to the main glasses 100, and the airtightness of the main glasses 100 is ensured by bonding with a sealant or adding an O-ring. The pressure plate 212 is provided on the base 211, and the handle 213 passes through the pressure plate 212 and is fixed to the base 211 by threads. When the electrical interface 220 of the first interface 200 and the electrical interface 510 of the first accessory are used in pairs, the electrical interface 510 of the first accessory can be loaded and unloaded by pressing the pressure plate 212 with the handle 213, which is convenient for installation.

[0064] like Figure 5 As shown, the first interface 200 includes 17 groups of connection spring pins, which are distributed in three circles inside and outside. The definition of the spring pins is shown in Table 1.

[0065] Table 1 Meaning of the first interface pin

[0066]

[0067]

[0068] from Figure 4 , Figure 5As can be seen from Table 1, pins 1 and 7 are connected to the power supply, and the broadband voltage output (3V to 5V) is used to drive the first external accessory (infrared detection module or ranging module or multi-spectral module or TV aiming module). Pin 1 is located at the center of the inner circle, and pin 7 is located in the middle circle. The spatial distance between pins 1 and 7 is relatively close, which can effectively reduce the impedance of power transmission. Pins 2 and 8 are grounded, which are used to balance the low potential level in the device connection. Pin 2 is located in the middle circle, and pin 8 is located in the outer circle. The spatial distance between pins 2 and 8 is relatively close, which can effectively reduce the impedance of power transmission. Pins 3 to 6, and pins 9 to 11 are data transmission interfaces, which are used for the external detection module to transmit video signals. Pin 13 is a clock signal, which is used for clock control when transmitting signals. The 7-bit data signal transmitted by pins 3 to 6, and pins 9 to 11 plus the 1-bit clock signal transmitted by pin 13 constitute a single-transmission video signal. Pin 12 is a detection signal, which can be freely set to high and low level detection, and is used to monitor the connection of the external detection module. Pin 14 and pin 15 are respectively used for frame detection and line detection of the transmitted image, and are used for frame check and line check of the transmitted image. If the check bit is not transmitted correctly, the corresponding frame and line data are discarded. Pin 16 and pin 17 are output and input signals, which are used to control the switch of the external detection module and other functions.

[0069] Furthermore, in other embodiments, the appearance and fixing method of the first interface 200 should be determined according to actual use. For example, the first interface 200′ based on the Picatinny rail connector can be selected. Figure 7 As shown), interfaces based on the dovetail tactical rail connector, two-plug interfaces, direct-plug interfaces, etc.

[0070] Furthermore, the infrared detection module, ranging module, multi-spectral module, and TV aiming module in the first accessory should be of moderate size and appropriate weight. When the first accessory is connected to the main glasses 100 through the first interface 200, the use of the first accessory will not be affected by the large size or heavy weight.

[0071] Further, if Figure 1 As shown, the second interface includes a WiFi antenna interface 320, a button interface 310, an encoder interface 330, a Beidou positioning interface, a Bluetooth interface, and a battery power interface. The second accessory includes: a WiFi antenna module 420, a button 410, an encoder 430, a Beidou positioning module, a Bluetooth module, and a battery power module 440. The WiFi antenna interface 320 is connected to the WiFi antenna module 420, the button interface 310 is connected to the button 410, the encoder interface 330 is connected to the encoder 430, the Beidou positioning interface is connected to the Beidou positioning module, the Bluetooth interface is connected to the Bluetooth module, and the battery power interface is connected to the battery power module 440.

[0072] Specifically, the first interface 200 is disposed on the left lens barrel 110 or the right lens barrel 120 . In this embodiment, the first interface 200 is disposed on the left lens barrel 110 .

[0073] Specifically, the second interface is set on the bracket 140, WiFi antenna interface 320, button interface 310, encoder interface 330, Beidou positioning interface, Bluetooth interface, battery power interface. Figure 1 As shown, the WiFi antenna interface 320 is arranged at the top of the bracket 140, near the right lens barrel 120, for transmitting the video, image, etc. detected by the glasses. The button interface 310 is arranged at the top of the bracket 140, near the left lens barrel 110, for connecting the button 410, and its function can be customized, such as: let the glasses take pictures, record the detected video at this time, etc. The encoder interface 330 is arranged on the side of the bracket 140, near the middle of the bracket 140; the battery power interface is arranged at the bottom of the bracket 140, near the middle between, for selecting functions in the glasses, turning pages, etc. In this embodiment, the button interface 310, the wireless interface, and the encoder interface 330 are all in Type-C form. A circular battery power interface is arranged at the bottom of the lens body for external power supply. A connecting cable is arranged at the rear of the left lens barrel 110 for transmitting video signals and power supply functions.

[0074] The schematic diagram of the main control circuit in the main glasses 100 is as follows: Figure 8 As shown. The main glasses 100 are binocular and binocular head-mounted night vision glasses, that is, they include two sets of objective lenses (including detectors), two sets of eyepieces (including displays) and a main control circuit. The objective lens is composed of several glass lenses with different focal lengths of non-spherical surfaces or super lenses arranged in an orderly manner in the direction of the optical axis, mainly to collect the light from the surrounding environment and project it onto the detector to facilitate the imaging of the detector. The detector mainly adopts a white micro-light detector, which mainly responds to light with a wavelength of 400nm to 1000nm, and is mainly used for night vision imaging in a white micro-light environment. The eyepiece is composed of several glass lenses with different focal lengths of non-spherical surfaces or super lenses arranged in an orderly manner in the direction of the optical axis, mainly to reasonably magnify the picture on the display, which is convenient for the operator to observe. The display is mainly based on a micro display, which is convenient for overall control of the weight of the head-mounted device, while improving the resolution, display brightness, color, etc. as much as possible, so that the observer has a certain degree of comfort when using the device. The micro display is mainly based on micro OLED, and most of them use standardized size displays such as 0.39 and 0.6, which is convenient for improving the maintainability, versatility and interchangeability of the equipment. Furthermore, in addition to micro OLED displays, LCOS, DLP, micro-LED, LCD and other displays may also be used.

[0075] The second accessories that can be matched with the periphery of the main control circuit include: WiFi antenna module 420, button 410, encoder 430, Beidou positioning module, Bluetooth module, battery power module 440, etc. WiFi antenna module 420, button 410, encoder 430, Beidou positioning module, Bluetooth module, battery power module 440, etc. are connected to the main control circuit board through the second interface. In actual use, the second accessories can be selected according to specific tasks and other requirements. One or more can be installed, or all can be selected. Furthermore, the second interface reserved on the main control circuit board should correspond to the second accessory one by one, and the second accessory cannot share the second interface on the main control circuit board, otherwise all options cannot be realized. This application modularizes many electrical functions (WiFi antenna module 420, button 410, encoder 430, Beidou positioning module, Bluetooth module, battery power module 440), which can be customized and matched according to customer requirements during production and sales, and can achieve different personalized services at a very low price.

[0076] This embodiment also provides an operating method of a multifunctional head-mounted device, which is applied to the multifunctional head-mounted device as described above. Fig. 9 As shown, the method includes:

[0077] S10: Acquire the status of the first interface 200 and the plurality of second interfaces;

[0078] Specifically, it includes determining whether a first accessory is installed on the first interface 200; and determining whether a corresponding second accessory is installed on each second interface.

[0079] S20: sending installation information and operation prompt information of the second accessories corresponding to the second interfaces to the user according to the states of the plurality of second interfaces;

[0080] Specifically, they include:

[0081] After determining that the WiFi antenna interface 320 is connected to the WiFi antenna module 420, the installation information that the WiFi antenna module 420 has been installed and the prompt information that the image transmission via WiFi is allowed are sent to the user;

[0082] After confirming that the button interface 310 is connected to the button 410, the installation information that the button 410 has been installed and the prompt information for assigning a value to the button 410 are sent to the user;

[0083] After confirming that the encoder interface 330 is connected to the encoder 430, the installation information that the encoder 430 has been installed and the prompt information for assigning a value to the encoder 430 are sent to the user;

[0085] After confirming that the Bluetooth interface is connected to the Bluetooth module, an installation message indicating that the Bluetooth module has been installed and a prompt message indicating that image transmission via Bluetooth is allowed are sent to the user;

[0086] After determining that the battery power interface is connected to the battery power module 440 , installation information indicating that the battery power module 440 has been installed and prompt information of the power, voltage, and duration read from the battery power module 440 are sent to the user.

[0087] S30: Determine installation information of a first accessory corresponding to the first interface 200 according to the state of the first interface 200;

[0088] Specifically, after determining that the first accessory is installed on the first interface 200, the feedback information of the first accessory is obtained, and the first accessory is determined to be an infrared detection module or a distance measurement module or a multi-spectral module or a TV aiming module according to the feedback information of the first accessory. Specifically, after the first accessory is connected, the contact is connected. It can be seen from Table 1 that the 12 spring pins are detection pins. When the 12 spring pins are connected, the main control circuit sends a detection signal, and the first accessory returns the accessory information. For example: the detection signal sent is "000", the first accessory receives "000", and the feedback information of the first accessory is "001", which means that the first accessory is an infrared detection module, the feedback information of the first accessory is "010", which means that the first accessory is a distance measurement module, the feedback information of the first accessory is "100", which means that the first accessory is a multi-spectral module, and the feedback information of the first accessory is "011", which means that it is a TV aiming module.

[0089] S40: Determine an image fusion algorithm according to the installation information of the first accessory.

[0090] Specifically, they include:

[0091] According to the type of the first accessory, an image fusion algorithm corresponding to the type of the first accessory is selected, and the image fusion algorithms include infrared-white low-light fusion algorithm, multi-spectral-white low-light fusion algorithm, ranging-white low-light fusion algorithm, multi-spectral-infrared fusion algorithm, infrared-ranging algorithm, and multi-spectral-ranging algorithm.

[0092] In a specific embodiment, Figure 8As shown, after the device starts running, the first step is to perform a self-check of the device; the second step, after the self-check is completed, determines whether the power battery module, WiFi antenna module 420, Bluetooth module, Beidou positioning module, button 410 and encoder 430, etc. have been installed according to the status of each second interface. If the power battery module is connected to the main control circuit through the power battery interface, the main control circuit reads the basic information of the power battery module, including voltage, power, etc., as well as some data that can be calculated from these basic data, including the remaining usage time of the device system, etc.; the WiFi antenna module 420 (Bluetooth module) is connected to the main control circuit through the WiFi antenna interface 420 (Bluetooth interface), and the device allows the sending or receiving of relevant image information through the WiFi module (Bluetooth module); if the Beidou positioning module is connected to the main control circuit through the Beidou positioning interface, the basic information of the Beidou positioning module is read, including direction, distance, etc.; if the button 410 and the encoder 430 are connected to the main control circuit, the user is reminded to assign values ​​to the button 410 and the encoder 430, for example: the video mode can be selected through the button 410, and the menu can be selected up and down or left and right through the encoder 430, etc. In the third step, after the detection of the second interface and the second accessory is completed, the device starts to prepare for operation. At this time, according to the state of the first interface 200, the installation information of the first accessory corresponding to the first interface 200 is determined, and according to the installation information of the first accessory, the image fusion algorithm is determined. Specifically, the first accessory includes: an infrared detection module, a ranging module, a multi-spectral module, and a TV aiming module, one of which is installed on the first interface 200. The main control circuit reads the image data of the first accessory and processes it, and performs image fusion processing with the low-light image collected by the main glasses 100. Due to the different types of first accessories, the image fusion algorithm selection is also different. For example, when an infrared detection module is connected externally, an infrared-low-light image fusion algorithm is selected; when a ranging module is connected externally, the ranging information is selected on the low-light image layer. In this embodiment, the device system integrates an infrared-white low-light fusion algorithm, a multi-spectral-white low-light fusion algorithm, a ranging-white low-light fusion algorithm, a multi-spectral-infrared fusion algorithm, an infrared-ranging algorithm, and a multi-spectral-ranging algorithm to meet the selection of different types of first accessories for use. The fourth step is to determine the image display mode according to the prompt information. For example, the user can select the image display mode according to the prompt information, for example, to select any one of the following modes: fused image display, single image display (low-light image, daylight TV image, infrared image), key image display (using local magnification picture-in-picture display or target real surrounding blur processing display, etc.), basic information selection display (stroke processing of the display area, etc.). The fifth step is to start displaying the selected image at the eyepiece end.

[0093] The specific use scenarios of the present invention are as follows: Taking the main glasses 100 as low-light night vision glasses as an example, facing different observation tasks and observation targets, the first accessories are selected before starting, including: power battery module, WiFi antenna module 420, Bluetooth module, Beidou positioning module, button 410 and encoder 430, etc., which can be selected individually or in multiple ways; then the first accessories for supplementary observation are selected, including: infrared detection module, ranging module, multi-spectral module, TV aiming module, etc., which can be selected or selected one of them for assembly. If no first accessories are installed, the main glasses 1001 can still realize the function of low-light night vision glasses; if the infrared detection module is installed, low-light infrared fusion images, pure infrared images, pure low-light images, etc. can be displayed, and the displayed images can be further processed, including key display, outline display, etc. After the accessories are assembled, they can be turned on for use.
