Description

Detailed Implementation

[0049] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0050] The components of the embodiments of this application described and illustrated in the accompanying drawings can be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0051] In the following text, the terms "comprising," "having," and their cognates, which may be used in various embodiments of this application, are intended only to indicate a particular feature, number, step, operation, element, component, or combination thereof, and should not be construed as primarily excluding the presence of one or more other features, numbers, steps, operations, elements, components, or combinations thereof, or adding the possibility of one or more combinations thereof.

Terms (such as those defined in commonly used dictionaries) shall be interpreted as having the same meaning as in their contextual meaning in the relevant technical field and shall not be construed as having an idealized or overly formal meaning, unless clearly defined in the various embodiments of this application.

[0053] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0054] An electronic compass, also known as a digital compass, uses the Earth's magnetic field to determine the direction of North Pole. It is typically manufactured using chips such as magnetoresistive sensors or fluxgate magnetometers. The working principle of an electronic compass is based on the Earth's magnetic field, which acts like a bar magnet, pointing from the magnetic south pole to the magnetic north pole. The strength of the Earth's magnetic field varies from approximately 0.4 to 0.6 gauss at different geographical locations. The magnetometer in an electronic compass measures three components of the magnetic field: two horizontal components and one vertical component. By measuring and calculating these components, the angle between the current direction and magnetic north, i.e., the heading angle, can be obtained.

[0055] Some cameras obtain positioning and orientation information with poor accuracy by installing electronic compasses. This method has poor positioning and orientation accuracy, is expensive, and cannot confirm the camera's attitude information, such as pointing, roll angle, and pitch angle. Therefore, this application provides an outdoor working device that can effectively solve the problems of poor positioning accuracy and limited positioning parameters in outdoor working devices.

[0056] The structure of this outdoor working equipment will be described below with reference to some specific embodiments.

[0057] Example 1:

[0058] This application provides an outdoor working device. Exemplarily, the outdoor working device includes: a device body 100 connected via a communication interface and a positioning and orientation component 200; the positioning and orientation component 200 is built into the device body 100, such as... Figure 1 As shown.

[0059] The positioning and orientation component 200 is used to acquire the positioning and orientation information and attitude information of the device body 100 based on received satellite navigation signals after drawing power from an external device or the device body 100. For example, the device body 100 may be, but is not limited to, a camera. The positioning and orientation information includes the device position and pointing, and the attitude information includes the device's pitch angle and roll angle.

[0060] This application provides outdoor working equipment with positioning and orientation information such as equipment pointing and location by embedding or attaching orientation and positioning components, as well as attitude information such as pitch angle and roll angle, by embedding or attaching orientation and positioning components on the outdoor working equipment, so as to facilitate the fine management of the equipment; the outdoor working equipment can also develop other functions based on the positioning and attitude information.

[0061] As an optional solution, the positioning and orientation component 200 is built into the device body 100. The device body 100 includes a device housing 110 and a device printed circuit board 120. The device housing 110 includes an upper shell 111 and a lower shell 112, such as... Figure 2 , Figure 3 As shown. The positioning and orientation component 200 is fixed to the inside of the device housing 111, or fixed to the device printed circuit board 120 on the side near the device housing 111.

[0062] As an optional solution, the positioning and orientation component 200 is fixed to the inside of the equipment housing 111 or the printed circuit board 120 near the equipment housing 111 by means of positioning pins and screws or slot locking. For example, it is rigidly connected to the printed circuit board 120 or the inside of the equipment housing 111 by means of positioning pins, slot positioning, screw locking, etc.

[0063] As an optional solution, to ensure that the antenna in the positioning and orientation component 200 can effectively receive satellite navigation signals, the equipment shell 111 is made of a non-metallic material, such as various high-hardness plastics or fiberglass, to ensure that the antenna can receive satellite navigation signals normally. When installing the antenna, the antenna used for positioning and orientation must have good conditions for receiving satellite navigation signals. Generally, the antenna is pointed upwards, that is, towards the sky, and there are no metal objects above or near the antenna that may interfere with its reception.

[0064] In one embodiment, the positioning and orientation component 200 further includes a component housing, a first antenna 211, and a second antenna 212. When the positioning and orientation component 200 is built into the device body 100, if the device housing 111 is made of metal, a signal through-hole is provided in the area of ​​the device housing 111 corresponding to the first antenna 211 and the second antenna 212, and the signal through-hole is covered with a non-metallic through-hole cover. Understandably, the diameters of the first antenna 211 and the second antenna 212 are both less than or equal to the diameter of the signal through-hole to ensure good satellite signal reception. That is, if the device housing 111 cannot be entirely made of non-metallic material, an opening can be provided near the antenna on the device housing 111, and the opening can be covered with a non-metallic material. The diameter of the opening should be larger than the antenna diameter, and the antenna should be as close as possible to the opening to ensure that the antenna can receive satellite positioning signals normally. When assembling the antenna, if... Figure 4 As shown, the geometric centers of the first antenna 211 and the second antenna 212 are both located on the geometric center line of the device housing 110, that is, the geometric centers of the two antennas are placed on the geometric center line of the device housing 110. It can be understood that when the positioning and orientation component 200 is externally mounted on the device body 100, the geometric centers of the first antenna 211 and the second antenna 212 are both located on the geometric center line of the component housing, that is, the geometric centers of the two antennas are placed on the geometric center line of the component housing.

[0065] Whether internal or external, when installing the antenna, the distance d between the geometric center of the first antenna 211 and the geometric center of the second antenna 212 must be greater than or equal to the preset distance d1; that is, the geometric center points of the two antennas must be spaced apart, and the preset distance is generally greater than or equal to 20cm. If the preset distance is too small, the directional information will have a significant error.

[0066] The distance between the phase center and the geometric center of the first antenna 211 is less than a preset difference; the preset difference is determined according to the accuracy requirements. The distance between the phase center and the corresponding geometric center of each antenna is very small, and it is best to set the phase center and geometric center of the antenna to overlap.

[0067] The distance between the phase center of the second antenna 212 and the geometric center of the second antenna 212 is less than a preset difference. Preferably, the phase center and the geometric center of the antenna overlap.

[0068] As an optional solution, when assembling the device housing 110 and the device body 100, the positioning and orientation component 200 is built into the device body 100, and there is a fixed preset angle between the geometric center line of the device housing 110 and the geometric center line of the device body 100; wherein, the preset angle is 0° or 90°.

[0069] As an optional solution, if the device body 100 is a camera, the lens direction of the camera is set to be in the same direction or opposite to the target direction in the positioning and orientation information calculated by the positioning and orientation component 200.

[0070] As an alternative solution, such as Figure 5 As shown, the positioning and orientation component 200 also includes a positioning and orientation module 240, an accelerometer 250, a main control chip 230, a communication module 270, a power management unit 260, and an accelerometer 250 rigidly connected to the device body 100. Two antennas are communicatively connected to the positioning and orientation module 240, and both the positioning and orientation module 240 and the accelerometer 250 are communicatively connected to the main control chip 230. The main control chip 230 is communicatively connected to the device body 100. Exemplarily, the device body 100 is a camera. The main control chip 230 can be an MCU.

[0071] The first antenna 211 and the second antenna 212 are both used to receive satellite navigation signals from the Global Navigation Satellite System; there are two independently operating antennas for receiving GNSS satellite positioning signals.

[0072] The positioning and orientation module 240 is used to acquire satellite navigation signals and output the positioning and orientation information of the device body 100 in combination with the satellite navigation signals. Specifically, the positioning and orientation module 240 determines the direction of the geometric vector formed by the phase points of the two antennas in a given coordinate system based on the differential measurement principle of satellite carrier phase signals. With north as the azimuth reference, it calculates the positioning information and heading angle information of the device body 100.

[0073] For example, the positioning and orientation module 240 may include a satellite orientation chip and a satellite positioning chip connected to the satellite orientation chip. The satellite positioning chip is connected to the first antenna 211, and the satellite orientation chip is connected to the second antenna 212. The satellite positioning chip is used to determine the positioning information of the device body 100 based on the navigation satellite signals received by the first antenna 211. The satellite orientation chip is used to determine the orientation information of the device body 100 based on the navigation satellite signals received by the second antenna 212. For details, please refer to some of the applicant's prior art applications, which will not be repeated here. Alternatively, the positioning and orientation module 240 may also use modules such as LG580P, BT-F9PK5, and M20D. Among them, LG580P is a full-system multi-band high-precision positioning and orientation GNSS module launched by Quectel Wireless Solutions; BT-F9PK5 is a centimeter-level positioning and orientation module with integrated antenna launched by Qianxun Location; and M20D is a module based on the Alice, a new generation 22nm process high-performance automotive-grade GNSS SOC chip from Beiyun Technology.

[0074] An accelerometer 250 is used to detect the acceleration information of the device body 100 and send the acceleration information to the main control chip 230; the accelerometer 250 includes, but is not limited to, MEMS. In this embodiment, the attitude (pitch angle, roll angle) of the device can be determined by measuring the acceleration of the three degrees of freedom (X / Y / Z axes).

[0075] Understandably, when the positioning and orientation component 200 is built into the device body 100, the accelerometer 250 is rigidly connected to the device printed circuit board 120 or the device housing 110, for example, by using positioning pins, slot positioning, screw locking, or other methods to ensure that the acceleration change value of the accelerometer 250 is consistent with that of the device body 100. When the positioning and orientation component 200 is externally attached to the device body 100, the accelerometer 250 is rigidly connected to the component housing, and the component housing is rigidly connected to the top or side surface of the device body 100 to ensure that the acceleration change value of the accelerometer 250 is consistent with that of the device body 100.

[0076] The main control chip 230 outputs attitude and positioning information obtained by combining acceleration information to the device body 100 via the communication module 270. The main control chip 230 calculates attitude information such as pitch and roll angles of the device body 100 by sensing changes in acceleration measured by the accelerometer 250. The communication module 270 may include a wired communication module 270 and a wireless communication module 270; the main control chip 230 establishes a communication connection with the device body 100 through either the wired or wireless communication module 270. The positioning and orientation component 200 can communicate with the outdoor working equipment via wired means, such as RS-232, RS-422, or RS-485. It can also communicate wirelessly with the outdoor working equipment, such as via Bluetooth or Wi-Fi, facilitating the outdoor working equipment to obtain the positioning, orientation, and attitude information provided by the positioning and orientation component 200.

[0077] The power management unit 260 is electrically connected to the power supply of the device body 100; the power management unit 260 is used to manage the power supply of the positioning and orientation component 200. The device body 100 supplies power to the positioning and orientation component 200 through the power management unit 260 via power leads. That is, the power management unit 260 is electrically connected to the positioning and orientation module 240, the accelerometer 250, and the main control chip 230.

[0078] As an optional solution, the positioning and orientation component 200 also includes: a battery and a solar charging device; the solar charging device charges the battery; the battery is used to power the positioning and orientation component 200.

[0079] When the positioning and orientation component 200 is built into the device body 100, the battery and solar charging device are mounted on the device housing 110 or the device printed circuit board 120; for example, they are fixed on the device housing 110 or the device printed circuit board 120 by means of positioning pins and screws, or dovetail groove locking.

[0080] To reduce costs, in this application, the main control chip 230 calculates the attitude information of the device body 100 based on acceleration information, which can be acceleration change information; the positioning and orientation module 240 calculates the positioning and orientation information of the device body 100 based on satellite navigation signals, which can be pseudorange observations and carrier phase observations; the main control chip 230 sends the acceleration change information, pseudorange observations, and carrier phase observations to the device body with a CPU possessing strong computing capabilities, so that the device body can calculate the position coordinates, azimuth, pitch angle, roll angle, and other attitude information of the device body 100. Among these, the pseudorange observation is the distance obtained by multiplying the propagation time of the ranging code signal transmitted by the satellite to the receiver antenna by the speed of light. Due to various errors during signal propagation, the pseudorange is not the true distance between the satellite and the receiver. The carrier phase observation is the difference between the phase of the carrier signal transmitted by the satellite at the receiver and the phase transmitted by the satellite. The carrier phase observation has high precision and is a core observation in satellite navigation and positioning.

[0081] To improve accuracy, in this application, the main control chip 230 calculates the attitude information of the device body 100 based on the acceleration information, which may be attitude information such as pitch angle and roll angle; the positioning and orientation module 240 calculates the positioning and orientation information of the device body 100 based on the satellite navigation signal, which may be positioning and orientation information such as position coordinates and azimuth angle; the main control chip 230 directly sends the high-precision position coordinates, azimuth angle, pitch angle and roll angle to the device body 100.

[0082] In one embodiment, the positioning and orientation module 240, the main control chip 230, the accelerometer 250, the communication module 270, and the first antenna 211 and the second antenna 212 are all disposed on the component printed circuit board 280. When the positioning and orientation component 200 is built into the device body 100, the component printed circuit board 280 is rigidly connected to the device shell 111 or the device printed circuit board 120.

[0083] like Figure 6As shown, the positioning and orientation module 240, accelerometer 250, main control chip 230, communication module 270, first antenna 211, and second antenna 212 are all mounted on a printed circuit board. This printed circuit board is placed inside the device housing 111 or on top of the device printed circuit board 120, and is rigidly connected to the device housing 111 or the device printed circuit board 120. For example, it can be rigidly connected to the upper surface of the device body 100 using methods such as positioning pins or screws. Furthermore, it must be ensured that the antennas face upwards.

[0084] In one implementation, such as Figure 7 As shown, the positioning and orientation module 240, accelerometer 250, main control chip 230, and communication module 270 are mounted on the first component printed circuit board 281; the first antenna 211 is mounted on the second component printed circuit board 282; and the second antenna 212 is mounted on the third component printed circuit board 283. The first antenna 211 and the second antenna 212 are connected to the positioning and orientation module 240 via a feed line. When the positioning and orientation component 200 is built into the device body 100, the first component printed circuit board 281, the second component printed circuit board 282, and the third component printed circuit board 283 are all rigidly connected to the device shell 111 or the device printed circuit board 120.

[0085] The positioning and orientation module 240, accelerometer 250, main control chip 230, and communication module 270 are mounted on a single printed circuit board (PCB). Two antennas are each mounted on a separate PCB. All three PCBs are located inside the device housing 111 or on the upper side of the device PCB 120, and are rigidly connected to either the housing 111 or the PCB 120. For example, they can be rigidly connected to the upper surface of the device body 100 using methods such as positioning pins or screws.

[0086] Examplely, the device body 100 is a camera. The printed circuit board (PCBA) carrying the accelerometer 250 and the positioning and orientation module 240 is fixed to a bracket inside the camera (the device PCBA 120 sometimes serves as a bracket) or to the camera housing (device housing 110) (sometimes the outer shell also acts as a bracket). Generally, once the bracket and camera housing are fixed, there is no displacement between them. When the camera moves, it moves the camera housing and bracket together, thereby moving the PCBA fixed to the bracket or housing, as well as components such as the accelerometer 250 and GNSS antenna, to sense changes in the camera's acceleration and orientation angle.

[0087] The rotation of the motor causes the camera to rotate, which in turn causes the camera's bracket and camera housing to rotate. Therefore, the rotation of the camera also causes the internal antenna to rotate, which in turn causes the PCBA, which carries the accelerometer 250 and the positioning and orientation calculation module, to rotate as well.

[0088] Example 2:

[0089] The difference between Embodiment 1 and Embodiment 2 is that the positioning and orientation component 200 is externally mounted on the device body 100, such as... Figure 8 As shown.

[0090] As an optional solution, when the positioning and orientation component 200 is externally mounted on the device body 100, the positioning and orientation component 200 includes a component housing and a communication interface disposed on the component housing, and is detachably connected to the device body 100 through the communication interface disposed on the component housing; when the positioning and orientation component 200 is externally mounted on the device body 100, the component housing is rigidly connected to the upper bottom surface or side surface of the device body 100 by means of positioning pins, slots, or screws. That is, the positioning and orientation component 200 is fixedly disposed inside the component housing, and is rigidly connected to the upper bottom surface or side surface of the device body 100 through the component housing, and is electrically connected to the device body 100 through the communication interface, such as... Figure 9 As shown.

[0091] As an alternative solution, such as Figure 10 As shown, the component housing includes an upper shell 221 and a lower shell 222; the upper shell 221 is made of non-metallic material.

[0092] The lower housing 222 of the component is rigidly connected to the upper bottom surface of the equipment body 100, and the upper housing 221 of the component is positioned facing upwards; for example Figure 8 As shown, the outer shell of the component is a cuboid mounted on the upper bottom surface of the device body 100.

[0093] Alternatively, the component housing is rigidly connected to the side of the device body 100, and the upper housing 221 of the component is positioned upwards. For example... Figure 9 As shown, the component housing is a cuboid mounted on the side of the device body 100. That is, the component housing is rigidly connected to the device body 100 via its lower shell or side, with the upper shell facing upwards to ensure the antenna's signal receiving surface is upward. The rigid connection between the component housing and the device body 100 can be achieved, for example, using locating pins, slots, or screws. The upward orientation of the upper shell of the component housing is towards the sky, as the antenna is also mounted upwards, thus ensuring the antenna receives navigation signals. Similarly, the positioning and orientation component 200 also includes a first antenna 211 and a second antenna 212; the specific installation requirements are the same as those for components built into the device body 100, and will not be repeated here.

[0094] As an optional solution, when assembling the component housing and the device body 100, with the positioning and orientation component 200 externally attached to the device body 100, there is a fixed preset angle between the geometric center line of the component housing and the geometric center line of the device body 100; wherein, the preset angle is 0° or 90°.

[0095] As an optional solution, if the device body 100 is a camera, then the lens direction of the camera is set to be the same as or opposite to the target direction in the positioning and orientation information calculated by the positioning and orientation component 200.

[0096] As an alternative, the positioning and orientation component 200 also includes a positioning and orientation module 240, an acceleration sensor 250, a main control chip 230, a communication module 270, a power management unit 260, and an acceleration sensor 250 rigidly connected to the device body 100. Specifically, it is the same as the positioning and orientation component 200 built into the device body 100, and will not be described in detail here.

[0097] Understandably, when the positioning and orientation component 200 is externally attached to the device body 100, the acceleration sensor 250 is rigidly connected to the component housing, and the component housing is rigidly connected to the top or side surface of the device body 100, so as to ensure that the acceleration sensor 250 and the acceleration change value of the device body 100 are consistent.

[0098] As an optional solution, the positioning and orientation component 200 also includes a battery and a solar charging device; when the positioning and orientation component 200 is externally attached to the device body 100, the battery and solar charging device are fixedly mounted on the component housing. For example, they are fixedly mounted on the component housing by means of positioning pins and screws, or by dovetail locking, etc.

[0099] In one embodiment, the positioning and orientation module 240, the main control chip 230, the accelerometer 250, the communication module 270, the first antenna 211, and the second antenna 212 are all fixedly mounted on the component printed circuit board 280. When the positioning and orientation component 200 is externally mounted on the device body 100, the component printed circuit board 280 is rigidly connected to the inner wall of the component housing.

[0100] like Figure 6 As shown, the positioning and orientation module 240, accelerometer 250, main control chip 230, communication module 270, first antenna 211, and second antenna 212 are all fixed on a printed circuit board. This printed circuit board is placed inside the device housing 111 or on top of the device printed circuit board 120, and is rigidly connected to the device housing 111 or the device printed circuit board 120. For example, it is rigidly connected to the top surface of the device body 100 using methods such as positioning pins or screws. Furthermore, it must be ensured that the antennas face upwards.

[0101] In one implementation, such as Figure 7 As shown, the positioning and orientation module 240, accelerometer 250, main control chip 230, and communication module 270 are fixedly mounted on the first component printed circuit board 281; the first antenna 211 is fixedly mounted on the second component printed circuit board 282; and the second antenna 212 is fixedly mounted on the third component printed circuit board 283. The first antenna 211 and the second antenna 212 are connected to the positioning and orientation module 240 via a feed line. When the positioning and orientation component 200 is externally mounted on the device body 100, the first component printed circuit board 281, the second component printed circuit board 282, and the third component printed circuit board 283 are all rigidly connected to the inner wall of the component housing.

[0102] This application provides high-precision positioning and orientation information, as well as attitude information including equipment pointing (azimuth), pitch angle, and roll angle, by embedding or attaching orientation and positioning components to outdoor working equipment. This facilitates refined management of the equipment, and other functions can be developed based on the positioning and attitude information.

[0103] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
