[0026] Research has found that the positioning and communication signals of mobile terminals in forests are very poor, making it difficult to meet the needs of forest resource inspections. In addition, the antennas of traditional Bluetooth modules are often single antennas, and the signals of single antennas will be biased in the horizontal or vertical directions. In addition, due to the altitude difference in forests, the signal bias in the horizontal or vertical direction has a greater impact on mobile terminals.

[0027] Based on the above research, the embodiments of the present disclosure provide an omnidirectional monitoring communication system and communication method for forests. The networking devices are networked and cover the entire forest area, and each networking device can form horizontal polarization waves 111a and vertical polarization waves 121a, that is, the mobile terminal can be at any location in the forest, and there will be no signal attenuation problem when sending and receiving signals, and the mobile terminal can realize real-time positioning and communication in the forest.

[0028] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the process of discovering the above problems and the solutions proposed by this disclosure for the above problems below should be the contributions made by the inventors to this disclosure during the disclosure process.

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0030] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0031] like Figures 1 to 9 As shown, at least one embodiment provides an omnidirectional monitoring communication system for forests, which includes: a plurality of networking devices 1; wherein each of the networking devices 1 is arranged in sequence at intervals so that the networking range of any of the networking devices 1 covers the adjacent networking devices 1 and is networked therewith, and at least one of the networking devices 1 is networked with a server; each of the networking devices 1 outputs a horizontally polarized wave 111a or a vertically polarized wave 121a to sense the communication equipment 2 within the networking range and be networked therewith.

[0032] Specifically, the communication device 2 may be a mobile terminal.

[0033] In at least one embodiment, by arranging the networking devices 1 at intervals in the woods, it is possible to ensure that the networking range covers the entire woods, and the networking devices 1 are networked with the server, so that the communication equipment 2 can communicate stably with the server in the woods, and the networking device 1 forms horizontally polarized waves 111a and vertically polarized waves 121a, which can penetrate the environmental factors and geographical factors in the woods to the maximum extent, overcome the constraints on signal transmission caused by environmental factors and geographical factors in the woods, and achieve the strongest networking signals in the horizontal and vertical directions in the woods, meeting the needs of real-time networking of the communication equipment 2 in the woods.

[0034] In at least one embodiment, the networking device 1 includes: a control module, a horizontally polarized wave forming module 11 and a vertically polarized wave forming module 12; the horizontally polarized wave forming module 11 is placed vertically, and the vertically polarized wave forming module 12 is placed horizontally; the control module is configured to drive the horizontally polarized wave forming module 11 and the vertically polarized wave forming module 12 to work, so as to form a horizontally polarized wave 111a and a vertically polarized wave 121a, respectively.

[0035] Specifically, based on weather changes (such as rainy days, snowy days, sunny days, etc.), polarized waves in different directions have different signal penetration capabilities in different weather conditions. At this time, the communication device 2 will disconnect from the previous group of network devices 1 and then connect to the next group of network devices 1. That is, the communication device 2 has the strongest connection signal with the horizontal polarized wave 111a in the previous group of network devices 1, but due to weather reasons, the communication device 2 is disconnected from the previous group of network devices 1, and the communication device 2 has the strongest connection signal with the vertical polarized wave 121a in the next group of network devices 1, and the communication device 2 is connected to the next group of network devices 1; or the communication device 2 has the strongest connection signal with the horizontal polarized wave 111a in the previous group of network devices 1, but due to weather reasons, the communication device 2 is disconnected from the previous group of network devices 1, and the communication device 2 is connected to the next group of network devices 1; 2 has the strongest connection signal with the horizontally polarized wave 111a in the latter group of network devices 1, and the communication device 2 is connected to the latter group of network devices 1; or the communication device 2 has the strongest connection signal with the vertically polarized wave 121a in the former group of network devices 1, but due to weather reasons, the communication device 2 is disconnected from the former group of network devices 1, and the communication device 2 has the strongest connection signal with the horizontally polarized wave 111a in the latter group of network devices 1, and the communication device 2 is connected to the latter group of network devices 1; or the communication device 2 has the strongest connection signal with the vertically polarized wave 121a in the former group of network devices 1, but due to weather reasons, the communication device 2 is disconnected from the former group of network devices 1, and the communication device 2 has the strongest connection signal with the vertically polarized wave 121a in the latter group of network devices 1, and the communication device 2 is connected to the latter group of network devices 1.

[0036] Specifically, see Figure 5 The horizontally polarized wave 111a refers to an electromagnetic wave whose electric field vector vibration direction is parallel to the ground (horizontal direction), that is, the signal is heavier (higher intensity) in the horizontal direction.

[0037] Specifically, see Figure 6 The vertically polarized wave 121a refers to an electromagnetic wave whose electric field vector vibration direction is perpendicular to the ground (vertical direction), that is, the signal is biased in the vertical direction (high intensity).

[0038] Specifically, the control module drives the horizontal polarization wave forming module 11 and the vertical polarization wave forming module 12 to work, that is, the horizontal polarization wave forming module 11 works and the vertical polarization wave forming module 12 does not work, or the horizontal polarization wave forming module 11 does not work and the vertical polarization wave forming module 12 works. On the one hand, the horizontal polarization wave forming module 11 and the vertical polarization wave forming module 12 do not interfere with each other. On the other hand, the electromagnetic wave formed by the horizontal polarization wave forming module 11 is biased in the horizontal direction and the vertical polarization wave forming module 12 is biased in the vertical direction. The horizontal polarization wave forming module 11 and the vertical polarization wave forming module 12 are frequently switched (5-10ms). The communication device 2 can sense either the horizontal polarization wave forming module 11 or the vertical polarization wave forming module 12, thereby ensuring stable communication of the communication device 2.

[0039] Specifically, see Figure 7 , each networking device 1 is respectively arranged in each area of ​​the forest, and the contour lines 3 in the figure represent the height difference.

[0040] Specifically, see Figure 8 , the networking device 1 forms a vertically polarized wave 121a along the F1 direction, and forms a horizontally polarized wave 111a along the F2 direction.

[0041] In at least one embodiment, see Figure 1 、 Figure 3 The horizontally polarized wave forming module 11 includes: a first external antenna 111 and a first relay K1; the first external antenna 111 is placed vertically, and the first external antenna 111 is electrically connected to the first relay K1; the control module is also configured to control the first relay K1 to be turned on, so as to drive the first external antenna 111 to form a horizontally polarized wave 111a.

[0042] Specifically, the Bluetooth networking range of the first external antenna 111 is 300-1000 meters.

[0043] Specifically, when the control module controls the first relay K1 to be turned on, the first external antenna 111 is powered on and operates, thereby being able to form a horizontally polarized wave 111 a.

[0044] Specifically, the control module controls the first relay K1 to be disconnected, and the first external antenna 111 is disconnected and powered off physically, not in standby state, and all energy is provided to the other external antenna to ensure that only one external antenna has full power output.

[0045] In at least one embodiment, see Figure 1 、 Figure 3 The vertical polarized wave forming module 12 includes: a second external antenna 121 and a second relay K2; the second external antenna 121 is placed horizontally, and the second external antenna 121 is electrically connected to the second relay K2; the control module is also configured to control the second relay K2 to be turned on, so as to drive the second external antenna 121 to form a vertical polarized wave 121a.

[0046] Specifically, the Bluetooth networking range of the second external antenna 121 is 300-1000 meters.

[0047] Specifically, when the control module controls the second relay K2 to be turned on, the second external antenna 121 is powered on and operates, thereby being able to form a vertically polarized wave 121 a.

[0048] Specifically, the control module controls the second relay K2 to disconnect, and the second external antenna 121 loses power and disconnects physically, not in standby state, and provides energy to the other external antenna to ensure that only one external antenna outputs full power.

[0049] Specifically, when the first relay K1 is turned on and the second relay K2 is turned off, the horizontal polarized wave 111a is switched to the vertical polarized wave 121a; when the first relay K1 is turned off and the second relay K2 is turned on, the vertical polarized wave 121a is switched to the horizontal polarized wave 111a.

[0050] Specifically, the distance between the first external antenna 111 and the second external antenna 121 is greater than 1 cm to avoid impedance mismatch caused by excessive coupling.

[0051] In at least one embodiment, see Figure 3 The networking device 1 also includes: a third relay K3; the third relay K3 is electrically connected to the first external antenna 111 in the horizontally polarized wave forming module 11 and the second external antenna 121 in the vertically polarized wave forming module 12 respectively; when the operation of the first external antenna 111 is switched to the operation of the second external antenna 121 or the operation of the second external antenna 121 is switched to the operation of the first external antenna 111, the control module is further configured to control the third relay K3 to be turned on, so that the resonant energy on the first external antenna 111 is superimposed on the second external antenna 121 or the resonant energy on the second external antenna 121 is superimposed on the first external antenna 111, until the resonant energy on the first external antenna 111 is dissipated or the resonant energy on the second external antenna 121 is dissipated, and the control module is further configured to control the third relay K3 to be turned off.

[0052] Specifically, at the moment when the first external antenna 111 or the second external antenna 121 loses power, resonant energy will still exist on the first external antenna 111 or the second external antenna 121, that is, by directing the resonant energy on the first external antenna 111 to the second external antenna 121, the initial power of the second external antenna 121 can be enhanced to ensure the connection power during switching, or by directing the resonant energy on the second external antenna 121 to the first external antenna 111, the initial power of the first external antenna 111 can be enhanced to ensure the connection power during switching.

[0053] Specifically, see Figure 3 , the first external antenna 111 is Figure 3 In L1, the second external antenna 121 is Figure 3In L2, points G, H, I, and J are connected to the power supply, and points A, B, C, D, E, and F are electrically connected to the control module, so that the control module can control the first relay K1 to be turned on or off, the second relay K2 to be turned on or off, and the third relay K3 to be turned on or off.

[0054] As an optional implementation for obtaining the installation altitude of the networking device 1, the control module is also configured to connect to the GNSS to obtain the installation altitude of the networking device 1; when any communication device 2 is networked with at least two of the networking devices 1, the corresponding two networking devices 1 respectively obtain the distance between themselves and the communication device 2; the server is configured to simulate the three-dimensional moving path of the communication device 2 based on the installation altitude of the networking device 1 and the distance between the networking device 1 and the communication device 2.

[0055] Specifically, GNSS is the Global Navigation Satellite System.

[0056] Specifically, each networking device 1 can know its corresponding coordinate positioning point during installation, and at the same time cooperate with GNSS to obtain the installation altitude, that is, to collect the three-dimensional coordinate points of each networking device 1, and then by obtaining the distance between at least two networking devices 1 and the communication device 2, the position of the communication device 2 can be calculated through the positioning algorithm, and finally a three-dimensional moving path is formed.

[0057] As another optional implementation for obtaining the installation altitude of the networking device 1, please refer to Figure 4 、 Figure 9 The networking device 1 also includes: a total station electrically connected to the control module; the total station is configured to obtain the installation altitude; when any communication device 2 is networked with at least two of the networking devices 1, the corresponding two networking devices 1 respectively obtain the distance between themselves and the communication device 2; the server is configured to simulate the three-dimensional movement path of the communication device 2 according to the installation altitude of the networking device 1 and the distance between the networking device 1 and the communication device 2.

[0058] Specifically, each networking device 1 can know its corresponding coordinate positioning point during installation, and at the same time cooperate with the total station to obtain the installation altitude, that is, to collect the three-dimensional coordinate points of each networking device 1, and then by obtaining the distance between at least two networking devices 1 and the communication device 2, the position of the communication device 2 can be calculated through the positioning algorithm, and finally a three-dimensional moving path is formed.

[0059] Specifically, see Figure 7, the communication device 2 is inspected on a known map with contour lines. When the distances between at least two networking devices 1 and the communication device 2 and the position coordinates of the networking device 1 itself are known, since the communication device 2 must be walking close to the ground, combined with the map of the forest, it is equivalent to calculating the position of the communication device 2 on a two-dimensional plane. Therefore, the position coordinates of the communication device 2 can be accurately calculated, and a three-dimensional moving path can be finally formed by real-time collection of the position coordinates of the communication device 2.

[0060] In at least one embodiment, see Figure 4 、 Figure 9 The networking device 1 also includes: a signal strength indication circuit; the signal strength indication circuit is electrically connected to the control module, the horizontal polarization wave forming module 11, and the vertical polarization wave forming module 12 respectively; when the horizontal polarization wave forming module 11 or the vertical polarization wave forming module 12 is networked with the communication device 2, the control module is further configured to obtain the corresponding signal strength value through the signal strength indication circuit; the control module is further configured to obtain the distance between the networking device 1 and the communication device 2 through the signal strength value.

[0061] Specifically, after the mobile terminal enters the signal coverage range of the networking device 1 and establishes a connection with the networking device 1, the networking device 1 receives the signal strength value from the mobile terminal in real time. The signal strength value attenuates as the distance increases and can be calculated through mathematical relationships.

[0062] In at least one embodiment, the control module is further configured to construct a distance monitoring model: ;in d is the distance between the networking device 1 and the communication device 2, A is the reference value of the signal strength at a distance of 1 meter. RSSI is the signal strength value, n is the path loss exponent.

[0063] Specifically, see Figure 7 , the distance between the networking device 1 and the communication device 2 is d , representing the spatial distance.

[0064] Specifically, the path loss index is determined according to the characteristics of the forest environment and has a value of 2-4. For example, different values ​​may be taken depending on the type of trees, shrubs, or vegetation planted in the forest.

[0065] Based on the same technical concept, at least one embodiment also provides a communication method, which includes: when the operation of the first external antenna 111 is switched to the operation of the second external antenna 121 or the operation of the second external antenna 121 is switched to the operation of the first external antenna 111, the control module is configured to control the third relay K3 to be turned on, so that the resonant energy on the first external antenna 111 is superimposed on the second external antenna 121 or the resonant energy on the second external antenna 121 is superimposed on the first external antenna 111, until the resonant energy on the first external antenna 111 is dissipated or the resonant energy on the second external antenna 121 is dissipated, the control module is also configured to control the third relay K3 to be turned off.

[0066] Based on the same technical concept, at least one embodiment also provides a communication method, which includes: when any communication device 2 is networked with at least two of the networking devices 1, the corresponding two networking devices 1 respectively obtain the distance between themselves and the communication device 2; the server is configured to simulate the three-dimensional moving path of the communication device 2 according to the installation altitude of the networking device 1 and the distance between the networking device 1 and the communication device 2.

[0067] To sum up, the present invention can ensure that the networking range covers the entire forest by arranging the networking devices at intervals in the forest, and network the networking devices with the server to enable the communication equipment to communicate stably with the server in the forest, and the networking devices form horizontally polarized waves and vertically polarized waves, which can penetrate the environmental factors and geographical factors in the forest to the maximum extent, overcome the constraints on signal transmission caused by environmental factors and geographical factors in the forest, and achieve the strongest networking signals in the horizontal and vertical directions in the forest, meeting the needs of real-time networking of communication equipment in the forest.

[0074] Only a few implementations and examples are described, and other implementations, enhancements, and variations can be made based on what is described and illustrated in this patent document.

[0075] A first component is directly coupled to a second component when there are no intervening components other than a line, trace, or another medium between the first and second components. A first component is indirectly coupled to a second component when there are intervening components other than a line, trace, or another medium between the first and second components. The term "coupled" and its variations encompass both direct and indirect couplings. Unless otherwise specified, the use of the term "about" is intended to include a range of 10% above and below the value.

[0076] Although several embodiments are provided in this disclosure, it should be understood that the disclosed systems and methods may be embodied in many other specific forms without departing from the spirit or scope of the present disclosure. The present examples are to be considered illustrative rather than restrictive, and the present invention is not to be construed as being limited to the details given. For example, various elements or components may be combined or integrated into another system, or certain features may be omitted or not implemented.

[0077] In the several embodiments provided herein, it should be understood that the disclosed devices and methods may also be implemented in other ways. The device embodiments described above are merely illustrative. For example, the flowcharts and block diagrams in the accompanying drawings show the possible architectures, functions, and operations of the devices, methods, and computer program products according to multiple embodiments of the present invention. In this regard, each box in the flowchart or block diagram may represent a module, program segment, or part of a code, which contains one or more executable instructions for implementing the specified logical functions. It should also be noted that in some alternative implementations, the functions marked in the boxes may also occur in an order different from that marked in the accompanying drawings. For example, two consecutive boxes can actually be executed substantially in parallel, or they may sometimes be executed in the opposite order, depending on the functions involved. It should also be noted that each box in the block diagram and / or flowchart, as well as the combination of boxes in the block diagram and / or flowchart, may be implemented using a dedicated hardware-based system that performs the specified functions or actions, or may be implemented using a combination of dedicated hardware and computer instructions.

[0078] In addition, without departing from the scope of the present disclosure, the discrete or separate techniques, systems, subsystems, and methods described and illustrated in the various embodiments may be combined or integrated with other systems, modules, techniques, or methods. Other items shown or discussed as coupled may be directly connected, or may be indirectly coupled or communicated through some interface, device, or intermediate component in an electrical, mechanical, or other manner. Other examples of changes, substitutions, and modifications may be determined by those skilled in the art without departing from the spirit and scope disclosed herein.
