Description

Technical Field

[0001] This invention relates to the field of Internet of Things (IoT) signal transmission, specifically to a mobile IoT directional signal transmission device. Background Technology

[0002] The Internet of Things (IoT) refers to connecting any object to a network through information sensing devices and according to agreed-upon protocols. Objects exchange and communicate information through information transmission media to achieve functions such as intelligent identification, positioning, tracking, and monitoring. Within a designated range, devices that need to establish communication can control or be controlled by transmitting and receiving signals. However, since some devices move within space, such as cameras and robotic vacuum cleaners in smart homes, their uncertain positions necessitate the use of omnidirectional antennas for signal transmission. However, the signal propagation of omnidirectional antennas is relatively short, limiting the movement range of these devices. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a mobile Internet of Things (IoT) directional signal transmission device, which solves the problem of omnidirectional antennas limiting the movement range of the device mentioned in the background section.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a mobile Internet of Things (IoT) directional signal transmission device, comprising multiple communication units that need to establish communication. Each communication unit includes a radio frequency (RF) unit for transmitting and receiving signals and a main control chip for processing signal information. The RF unit is connected to an antenna unit, which includes an omnidirectional antenna and a directional antenna, and an adjustment base for adjusting the tilt direction and tilt angle of the directional antenna. Each communication unit includes at least one movable communication unit. The communication unit transmits the origin coordinate position and the destination coordinate position through the omnidirectional antenna. During movement, it transmits real-time position coordinates at intervals. The communication unit that needs to establish communication with the communication unit receives the coordinate position through the omnidirectional antenna and records the position of the directional antenna pointing to the destination coordinates through the main control chip. Before communicating with the communication unit, the communication unit adjusts the position of the directional antenna. If the coordinate position remains unchanged after multiple intervals during movement, the coordinate position is determined as the destination orientation. The communication unit that needs to establish communication with the communication unit receives the coordinate position through the omnidirectional antenna and, based on its own position and movement, points to the communication unit in real time through the main control chip. The communication unit actively adjusts the directional antenna to point to the communication unit it is communicating with.

[0005] Preferably, the directional antenna includes a signal receiving line and a signal transmitting line, which are independent and connected to the adjustment base respectively.

[0006] Preferably, the antenna unit includes only a directional antenna. When the directional antenna emits an omnidirectional signal, it rotates multiple times to emit signals in all directions.

[0007] Preferably, it also includes a relay unit for recording the location information of each communication unit. The location of the relay unit is fixed. During the movement of the communication unit, the communication unit sends coordinate information to the relay unit in real time. Before establishing communication with other communication units, the communication unit first establishes communication with the relay unit to determine the location of the communication unit being communicated with, and sends its own location to the relay unit. The relay unit forwards the location information to the communication unit being communicated with. The two communication units that have established communication adjust the base to make the directional antennas between them concentric, and determine the location information with the relay unit multiple times per unit time.

[0008] Preferably, there are multiple relay units, all of which share information. The relay units and communication units transmit information through an omnidirectional antenna, and the communication units establish information transmission with different relay units by switching signal strength.

[0009] Preferably, the relay units are provided with an information receiving end and an information sending end. The information collected by the relay unit is sent to the adjacent relay unit through the information sending end, and the relay unit accumulates the information and sends it to the information receiving end of the next relay unit through the information sending end.

[0010] Preferably, an information processing unit is provided between the relay units. The information processing unit is used to record the location information of the corresponding communication unit. Each relay unit can upload, modify, and download the corresponding location information.

[0011] Preferably, the directional antenna includes a metal antenna end and a housing end, with a base elastically hinged to the bottom of the housing end. The adjustment base includes a toothed ring disposed on the outer ring of the base and a power source for driving the toothed ring to rotate. A drive unit for driving the housing end to swing is disposed above the base.

[0012] Preferably, the two directional antennas are located at opposite ends of the communication unit, and the spheres formed by the rotation of the two directional antennas do not contact each other.

[0013] Preferably, the outer ring of the directional antenna is fitted with a protective cover.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This mobile IoT directional signal transmission device first transmits location information, and then adjusts the angles of the directional antennas of the two communication units that establish communication based on the location information. Through the corresponding directional antennas, it can achieve the effect of long-distance signal transmission and stable signal transmission.

[0015] 2. This mobile IoT directional signal transmission device uses an omnidirectional antenna to broadcast the coordinates of each communication unit and receive coordinates from other communication units. By adjusting the directional antenna using these two coordinates, signal propagation efficiency is optimized, resulting in more stable transmission, higher effective throughput, and smoother transmission. However, this also presents a problem: when the omnidirectional antenna is far apart, signal loss between two communication units can easily occur.

[0016] 3. This mobile IoT directional signal transmission device determines the position between two communication units that establish communication through a relay unit, and adjusts the angle of the directional antenna according to the other party's position information. With this setting, even if the two communication units are far apart, communication can be established by adjusting the directional antenna.

[0017] 4. This mobile IoT directional signal transmission device has an antenna unit consisting only of a directional antenna. When the directional antenna emits an omnidirectional signal, it rotates multiple times to emit signals in all directions. In this way, the location of the communication unit is broadcast multiple times in all directions by rotating the directional antenna. At the same time, the directional antenna receiving the signal also rotates multiple times. When the two rotations are aligned, the signal location information can be transmitted. This setting eliminates the need for an omnidirectional antenna. By rotating the directional antenna for receiving and transmitting information multiple times and emitting signals multiple times, the device receives information when aligned and actively adjusts the directional antenna when it is determined that communication needs to be established. This setting enables signal transmission over a longer distance.

[0018] 5. In this mobile IoT directional signal transmission device, an information processing unit is set between the relay units. The information processing unit is used to record the location information of the corresponding communication unit. Each relay unit can upload, modify, and download the corresponding location information. Since the relay units need to establish omnidirectional antenna communication with the communication units, multiple relay units are set up to maintain signal coverage. Multiple relay units transmit the collected location information to the information processing unit through wired or wireless means to wait for it to be read by other relay units. Through this setting, a wider relay unit signal coverage can be established. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0022] It should be noted that all directional indications in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0023] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0024] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. If the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed in this application.

[0025] like Figure 1 - Figure 5As shown, a mobile IoT directional signal transmission device includes multiple communication units 1 that need to establish communication, such as fixed devices like a robot vacuum cleaner and a humidity sensor in a smart room, as well as items containing movable devices. These items need to be connected via IoT signals. Each communication unit 1 includes a radio frequency (RF) unit 2 for transmitting and receiving signals and a main control chip 3 for processing signal information. The RF unit 2 is connected to an antenna unit 4, which includes an omnidirectional antenna 41 that transmits and receives non-directional signals with a wide signal coverage area; a directional antenna 42 that receives and transmits signals only in a specific direction with high signal quality; and an adjustment base 43 for adjusting the tilt direction and tilt angle of the directional antenna 42. Each communication unit 1 includes at least one movable communication unit 1, or multiple movable communication units 1. Two communication units 1 can be considered to move relative to each other. Each communication unit 1 transmits its origin and destination coordinates via the omnidirectional antenna 41. During movement... The communication unit 1 transmits real-time position coordinates intermittently, ensuring that it always maintains a signal transmission state. Communication units 1 that need to establish communication with other communication units 1 receive coordinates via omnidirectional antenna 41 and record the position of the directional antenna 42 pointing to the destination coordinates via the main control chip 3. Before communicating with other communication units 1, the main control chip 3 adjusts the position of the directional antenna 42, pre-determining the required orientation but not performing the adjustment. The antenna continues to communicate with other communication units 1. If the received coordinates remain unchanged during movement, this position is determined as the destination orientation. This allows the communication unit 1 to quickly find the position pointed to by the directional antenna 42 when it needs to establish communication with a moved communication unit 1, even when the communication unit 1 is not moving. The communication unit 1 that needs to establish communication with the moved communication unit 1 receives coordinates via omnidirectional antenna 41 and, based on its own position and movement, points to the communication unit 1 in real-time via the main control chip 3. The moved communication unit 1 actively adjusts the directional antenna 42 to point to the communication unit 1 it is communicating with. In summary, communication units 1 broadcast their coordinate positions to each other via omnidirectional antenna 41 and receive coordinate positions from other communication units 1. They then use these two coordinate positions to adjust directional antenna 42, optimizing signal propagation efficiency and resulting in more stable transmission, higher effective throughput, and smoother transmission. However, this also presents a problem: when the omnidirectional antenna 41 is at a greater distance, signal loss may occur between the two communication units 1.

[0026] It also includes a relay unit 5 for recording the location information of each communication unit 1. The position of the relay unit 5 is fixed. During the movement of the communication unit 1, it sends coordinate information to the relay unit 5 in real time. The distance between the communication unit 1 and the relay unit 5 is relatively close, but the distance between adjacent communication units 1 is relatively far. Before establishing communication with other communication units 1, the communication unit 1 first establishes communication with the relay unit 5 to determine the position of the communication unit 1 to be communicated with, and sends its own position to the relay unit 5. The relay unit 5 forwards the position information to the communication unit 1 to be communicated with. The two communication units 1 that have established communication adjust the base 43 to make the directional antenna 42 between them concentric. The relay unit 5 determines the position between the two communication units 1 that have established communication, and adjusts the angle of the directional antenna 42 according to the position information of the other party. With this setting, even if the distance between the two communication units 1 is relatively far, communication can be established by adjusting the directional antenna 42.

[0027] The position information is determined with the relay unit 5 multiple times within a unit time. Since one or both communication units 1 may be displaced during communication, the position information of the other party must be read again through the relay unit 5 within a unit time to adjust the angle of the directional antenna 42 in a timely manner.

[0028] There are multiple relay units 5, and all relay units 5 share information. The relay units 5 and the communication unit 1 transmit information through the omnidirectional antenna 41. The communication unit 1 establishes information transmission with different relay units 5 by switching the signal strength. This setting can ensure that the mobile communication unit 1 can select among multiple relay units 5, thereby expanding the mobile range of the communication unit 1.

[0029] An information processing unit 6 is set between the relay units 5. The information processing unit 6 is used to record the location information of the corresponding communication unit 1. Each relay unit 5 can upload, modify and download the corresponding location information. Since the relay unit 5 needs to establish communication with the omnidirectional antenna 41 with the communication unit 1, multiple relay units 5 are set to maintain signal coverage. Multiple relay units 5 transmit the collected location information to the information processing unit 6 through wired or wireless means to wait for it to be read by other relay units 5. Through this setting, a wider signal coverage of relay units 5 can be established.

[0030] Example 2: The directional antenna 42 includes independent signal receiving and transmitting lines. This independent design avoids mutual interference during signal transmission, ensuring the accuracy and stability of signal reception and transmission. The independently configured signal receiving and transmitting lines can be optimized and adjusted according to actual needs, such as for different signal frequencies and transmission distances, to improve the overall performance of the directional signal transmission device. Furthermore, in case of a fault, the independent design facilitates quick identification of the problem—whether it is a faulty receiving or transmitting line—allowing for more efficient repair and replacement, reducing equipment downtime, and improving operational efficiency. Each line is individually adjusted by connecting to the adjustment base 43.

[0031] Antenna unit 4 includes only directional antenna 42. When directional antenna 42 emits an omnidirectional signal, it rotates multiple times to emit signals in all directions. In this way, the location of the communication unit 1 is broadcast multiple times in all directions by rotating directional antenna 42. At the same time, directional antenna 42, which receives signals, also rotates multiple times. When the two rotations are aligned, signal location information can be transmitted. This setting eliminates the need for omnidirectional antenna 41. By rotating directional antenna 42 multiple times to receive and transmit information, it emits signals multiple times, receives information transmission when aligned, and actively adjusts directional antenna 42 when it is determined that communication needs to be established. This setting enables long-distance signal transmission.

[0032] Information receiving end and information transmitting end are set between relay units 5. The information collected by relay unit 5 is sent to the adjacent relay unit 5 through the information transmitting end. The relay unit 5 accumulates the information and sends it to the information receiving end of the next relay unit 5 through the information transmitting end. When relay unit 5 collects signal A, it sends the collected information to the next relay unit 5 and overwrites the original signal A in the relay unit 5. When the relay unit 5 receives information B, it transmits information A and information B together to the next relay unit 5 and overwrites its corresponding content. The information is transmitted in a ring among multiple relay units 5. When a relay unit 5 detects information, the relay units 5 on the ring overwrite the information in turn, thereby maintaining information synchronization.

[0033] The directional antenna 42 includes a metal antenna end 421 and a housing end 422. The bottom end of the housing end 422 is elastically hinged to a base 423. The adjustment base 43 includes a gear ring 431 disposed on the outer ring of the base 423 and a power source 432 for driving the gear ring 431 to rotate. The power source 432 is a servo motor that drives the gear to rotate. The gear drives the gear ring 431 to rotate to achieve oscillation. A drive part 433 for driving the housing end 422 to oscillate is disposed above the base 423. The drive part 433 adopts a servo motor direct drive or transmission drive. Thus, only one mechanical solution is disclosed, which is the simplest mechanical solution.

[0034] Two directional antennas 42 are located at the two ends of the communication unit 1 respectively. The spheres formed by the rotation of the two directional antennas 42 do not touch each other. This arrangement ensures that the directional antennas 42 will not interfere with each other during the swinging process.

[0035] The outer ring of the directional antenna 42 is fitted with a protective cover 7. The protective cover 7 is made of a material that does not affect signal transmission. By setting the protective cover 7, the directional antenna 42 can be prevented from being damaged by collision.
