Description

Technical Field

[0001] The utility model relates to the technical field of AGV trolley communication, in particular to a micro base station for communication of multiple AGV trolleys. Background Art

[0002] The micro base station for AGV communication refers to a system in which multiple automatic guided vehicles (AGVs) and micro base stations equipped with corresponding communication functions are deployed in a factory, warehouse or other places to achieve wireless communication and data exchange between multiple AGVs and between AGVs and the central control system. The system architecture of micro base stations for multiple AGVs usually includes the following components: the AGV is responsible for transporting goods or performing tasks within the site, and has autonomous navigation and motion control capabilities. Each AGV is equipped with a communication module for communicating with the micro base station; the micro base station serves as a relay point for communication and a hub for data transmission. The micro base station is responsible for receiving signals sent by the AGV, processing data and forwarding it to the target device or central control system; through the system of micro base stations for multiple AGVs, application scenarios such as automated logistics and intelligent warehousing can be realized, which can improve operating efficiency and reduce labor costs, and can flexibly expand the system and develop customized functions according to specific needs.

[0003] To ensure the stability and reliability of communication between the AGV and the micro base station for communication, full signal coverage is very important. When multiple AGVs and micro base stations are deployed in a venue, it is necessary to ensure that the communication signal can cover the movement range of each AGV, and the signal interaction of the AGV needs to reach more than 80% of the signal coverage to ensure that they can communicate, transmit data and interact with each other in real time. Ways to enhance the coverage and direction of the signal include adjusting the antenna angle to a more horizontal direction to increase the horizontal coverage of the signal, which is suitable for scenarios where it is necessary to expand the signal coverage on the horizontal plane. By adjusting the antenna angle, the main coverage direction of the signal can be changed to adapt to the layout and needs of different work areas and achieve more accurate signal coverage.

[0004] The patent with the current publication number CN207612429U discloses a micro communication base station, including a cover body, a main body, a dehumidification box and a circuit board, the bottom end of the main body is evenly provided with heat dissipation fins, and one end of the top of the main body is hinged with the cover body through a hinge, both sides of the top of the cover body and the end away from the hinge are equipped with fixed locks, and the top of the main body near the fixed lock is equipped with locks that cooperate with the fixed locks, and the main body is connected to the cover body through the locks, an indoor interface is provided on one side of the main body near one end of the hinge, and an outdoor interface is provided on the other side of the main body near one end of the hinge, a display screen is installed at the middle position of one end of the main body near the hinge, and a power cord interface is provided on the main body between the display screen and the indoor interface; although the above device solves the problem of easy disassembly and assembly of the device.

[0005] However, the above technical solution still has the following problems:

[0006] The signal antenna of the micro base station in the technical solution is stored inside the body of the micro base station, which weakens the signal interaction capability of the micro base station and reduces the signal penetration capability. When performing signal interaction with AGV vehicles, a signal coverage range of more than 80% is required. The coverage range of the micro base station is not enough to support wireless communication and data exchange between multiple AGVs and between AGVs and the central control system, causing the AGV vehicle to stop running and affecting operating efficiency. Utility Model Content

[0007] In view of the deficiencies of the prior art, the present invention provides a micro base station for communication between multiple AGVs, so as to solve at least one of the problems raised by the background technology, such as improving the signal coverage and strength of the micro base station.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a micro base station for communication between multiple AGV vehicles, including a base station body, a signal receiving mechanism installed on the top of the base station body, multiple signal antennas installed on the outside of the signal receiving mechanism, and a feeder installed in the signal receiving mechanism, one end of the feeder is connected to the signal output end of the base station body, and the other end is connected to the signal antenna.

[0009] Furthermore, the signal receiving mechanism includes a signal tower and a fixed ring. The top of the base station body is fixedly connected to the fixed ring. The top of the fixed ring is rotatably connected to the signal tower. The surface of the fixed ring is provided with a sliding groove that fits and connects to the bottom of the signal tower.

[0010] Furthermore, a wire channel is opened at the bottom of the signal tower, and the feeder passes through the wire channel and is connected to the signal antenna.

[0011] Furthermore, a plurality of circular holes are opened on the outside of the signal tower, and the signal antenna passes through the circular holes and is connected to the feeder line.

[0012] Furthermore, one end of the signal antenna is fixedly connected to a connecting base, the outer side of the connecting base is threadedly connected to the inner wall of the circular hole, the bottom of the connecting base is threadedly connected to an antenna connector, and the other end of the antenna connector is connected to the feeder.

[0013] Furthermore, a top cover is threadedly connected to the top of the signal tower, and a handle is fixedly connected to the surface of the top cover.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model makes an adjustable setting for the signal receiving mechanism of the micro base station. When faced with the need for signal interaction of a large number of AGVs, the signal coverage range can be improved and the effect of local signals can be increased.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] like Figures 1 to 5As shown, a micro base station for communication between multiple AGV vehicles includes a base station body 1, a signal receiving mechanism 2 is installed on the top of the base station body 1, a plurality of signal antennas 4 are installed on the outside of the signal receiving mechanism 2, a feeder 5 is installed inside the signal receiving mechanism 2, one end of the feeder 5 is connected to the signal output end of the base station body 1, and the other end is connected to the signal antenna 4.

[0024] like Figure 1 As shown, a micro base station for communication between multiple AGVs in the utility model is similar to the structure of an existing micro communication base station, such as the micro communication base station disclosed in the patent publication number CN207612429U. The main improvement of the utility model is that the signal antenna of the micro base station is adjustable, such as Figures 1 to 5 As shown, when a micro base station for communication with multiple AGV vehicles in the utility model is in use, the staff opens the signal receiving mechanism 2, inserts the signal antenna 4 into the surface of the signal receiving mechanism 2, faces the signal antenna 4 to the direction in which the signal needs to be transmitted, and then connects one end of the feeder 5 to the base station body 1, and the other end to the installed signal antenna 4. After the signal receiving mechanism 2 is installed, the base station body 1 is opened to make the signal cover the AGV vehicle site; when the base station body 1 is in use, it is necessary to temporarily adjust the direction facing the signal, and the signal receiving mechanism 2 can be rotated to avoid reinstalling the signal receiving mechanism 2. At the same time, when the signal needs to be enhanced, multiple signal antennas 4 can be installed and disassembled in the same direction. After the feeder 5 is connected to it, the feeder 5 forms a signal beam to enhance the signal strength in the same direction, ensuring that the communication signal can cover the movement range of each AGV vehicle.

[0025] like Figure 2 As shown, the signal receiving mechanism 2 includes a signal tower 201 and a fixed ring 3. The top of the base station body 1 is fixedly connected to the fixed ring 3, the top of the fixed ring 3 is rotatably connected to the signal tower 201, and the surface of the fixed ring 3 is provided with a slide groove 301 that is fitted and connected to the bottom of the signal tower 201.

[0026] Specifically, the setting of the fixing ring 3 provides the signal tower 201 with the effect of rotating on the surface of the base station body 1, so that the direction facing the signal antenna 4 can be changed without reassembling it, which provides convenience for operations that require temporary adjustment of the signal direction.

[0027] like Figure 3 As shown, a wire channel 203 is provided at the bottom of the signal tower 201 , and the feeder line 5 passes through the wire channel 203 and is connected to the signal antenna 4 .

[0028] Specifically, by configuring the signal tower 201 in this way, the feeder 5 is not affected when rotating, a stable connection between the feeder 5 and the signal antenna 4 is ensured, the consistency of the signal frequency is ensured, signal interruption is prevented, and the AGV remains in continuous operation.

[0029] like Figures 2 to 3 As shown, a plurality of circular holes 202 are opened on the outer side of the signal tower 201 , and the signal antenna 4 passes through the circular holes 202 and is connected to the feeder 5 .

[0030] Specifically, through this arrangement, the signal antenna 4 can be installed at any height and direction on the surface of the signal tower 201, which can change the main coverage direction and signal strength of the signal, further improving the environmental adaptability of the base station body 1 and the effect of comprehensive signal coverage.

[0031] like Figures 1 to 4 As shown, one end of the signal antenna 4 is fixedly connected to a connecting base 401 , the outer side of the connecting base 401 is threadedly connected to the inner wall of the circular hole 202 , the bottom of the connecting base 401 is threadedly connected to an antenna connector 402 , and the other end of the antenna connector 402 is connected to the feeder 5 .

[0032] Specifically, through this arrangement, when the signal antenna 4 is fixed on the surface of the signal tower 201, the connecting base 401 provides a stable supporting force for the signal antenna 4, preventing movement between the signal antenna 4 and the feeder 5, which may cause signal fluctuations. At the same time, the antenna connector 402 also improves the stability between the signal antenna 4 and the feeder 5, ensuring that the signal remains stable when the signal tower 201 is rotated.

[0033] like Figure 1 As shown, a top cover 204 is threadedly connected to the top of the signal tower 201 , and a handle 6 is fixedly connected to the surface of the top cover 204 .

[0034] Specifically, through this arrangement, the staff can quickly open the signal receiving mechanism 2 and quickly change the position of the signal antenna 4 to ensure that the signal coverage rate can be guaranteed to be within the required range, thereby improving the work efficiency of the staff.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
