[0031] In one embodiment, a wireless device is provided, comprising: an antenna module 1, a main control module 2, a base 3, a carrier module 4, and an external interface 5. Please refer to [reference needed]. Figure 1 The antenna module 1 includes a dual-band antenna 11, a receiving unit 12, a positioning antenna 13, and a communication antenna 14. The dual-band antenna 11 and the receiving unit 12 are connected in a one-to-one correspondence.

Specifically, the external interface 5 may include a power interface 51, the inner port of which is connected to the main control module 2 to provide power to the main control module 2.

[0032] Figure 1 , Figure 2 Taking the four-sided dual-band antenna 111 as an example, Figure 1To illustrate the internal structure, only a portion of the side dual-band antennas is shown (one side dual-band antenna is omitted); the four side dual-band antennas form a square sidewall, preferably a rectangular sidewall. In different embodiments, the number of side dual-band antennas is not necessarily four; for example, it can be five, with five side dual-band antennas forming a pentagonal sidewall, and so on.

[0033] In one embodiment, the positioning antenna can be a GPS antenna. The communication antenna can be a 4G antenna.

[0034] In one embodiment, the communication antenna 14 can be mounted on the upper surface of the base 3 via the communication antenna mounting bracket 141, such as... Figure 1 As shown.

The antenna plate 1101 is disposed outside the reflector 1102. There are two antenna plates 1101, each at a different distance from the reflector 1102, used to receive 2.4GHz and 5.8GHz frequency signals respectively. The receiving unit 12 is fixed to the inner side of the reflector 1102. One end of the signal transmission feed line 1103 is connected to the antenna plate 1101, and the other end is connected to the receiving unit 12. The outer side of the reflector 1101 refers to the side of the reflector furthest from other dual-band antennas. A positioning antenna 13 is fixed to the upper surface of the reflector of the top dual-band antenna 112.

[0036] In one embodiment, the receiving unit includes: an RF board 121 and a shielding shell 122, such as... Figure 3b As shown in 3c, the radio frequency board 121 is fixed inside the reflector 1102, and the shielding shell 122 is also fixed inside the reflector 1102, forming a closed cavity with the reflector to enclose the radio frequency board 121 within it, thereby providing electromagnetic shielding for the radio frequency board 121 and reducing interference from the external electromagnetic environment. Figure 3b The shielding shell 122 is a transparent shell, so the radio frequency board 121 can be seen through the shielding shell 122.

[0037] In one embodiment, the base 3, corresponding to the dual-band antenna, is a polygonal base. The supporting module includes at least four support units 41, each corresponding to a side dual-band antenna 111. Different support units 41 are respectively arranged corresponding to different sides of the base 3, such as... Figure 4 As shown. When the number of side dual-band antennas 111 is four, the base 3 is a quadrilateral base, preferably a square base.

[0038] In this embodiment, the support unit 41 includes a fixing part 411 and an L-shaped support part 412 arranged sequentially. The fixing part 411 is used to fix the L-shaped support part 412 to the base 3. The L-shaped support part is L-shaped, with one end near the fixing part 411 perpendicular to the base 3 and the other end parallel to the base 3. The end perpendicular to the base is used to fix the side dual-band antenna, such as... Figure 5 As shown. At least four L-shaped support portions 412 have their other ends used to fix the top-surface dual-band antenna 112. The L-shaped support portions 412 are located inside the dual-band antenna, as shown. Figure 1 , Figure 5 As shown.

[0039] In one embodiment, the external interface 5 may further include: a wireless network interface 52 and / or a wired network interface 53, such as... Figure 5 As shown. The internal ports of the wireless network interface 52 and / or the wired network interface 53 are connected to the main control module 2 to provide a network for the main control module 2 to communicate with external devices (such as a management platform). In addition to the communication antenna 14, the wireless network interface 52 and / or the wired network interface 53 are also provided, which means that multiple communication methods are preset, providing redundancy options, ensuring communication effect, and making it more applicable.

[0040] As an example, the wireless network interface 52 can take the form of a SIM card socket, into which a SIM card can be inserted for wireless networking.

[0041] In one embodiment, the main control module 2 includes: a main control board 21, a main control board housing 22, and a supporting angle iron 23, such as... Figure 6 As shown. The supporting angle iron 23 is used to fix the main control board housing 22 to the upper surface of the base 3, and the main control board 21 is installed in the main control board housing 22. Furthermore, the bottom of the main control board housing 22 is distributed along a diagonal line of the base 3, which can further reduce the size of the wireless device.

[0042] In another embodiment, the wireless device further includes: a housing 6, such as Figure 7 As shown, the outer casing 6 and the base 3 are connected to form a closed cavity, within which the antenna module 1, the main control module 2, and the carrier module 4 are enclosed. The outer casing isolates the internal components of the wireless equipment—namely, the antenna module 1, the main control module 2, and the carrier module 4—from the external environment, protecting them from environmental corrosion, improving equipment testing accuracy, and extending the equipment's lifespan.

[0043] In one embodiment, the outer casing is divided into two interconnected parts: a casing body 61 and a metal liner 62, such as... Figure 7 , 8As shown. The metal liner 62 is located in the portion of the outer shell near the base 3, and the outer shell is connected to the base 3 through the metal liner 62. By using a metal liner for the portion connected to the base, the overall strength of the outer shell can be ensured. The shell body is a high-transmittance shell body, such as an electronic glass fiber epoxy prepreg shell body. The dual-band antenna and positioning antenna are located in the area enclosed by the shell body. This shell body will not affect the signal reception of the antenna, and has high strength, excellent corrosion resistance, and good electrical insulation.

[0044] In one embodiment, the outer casing and the base are sealed together by a sealing structure, thus forming a sealed space. Furthermore, the external interface also includes a waterproof and breathable valve to maintain pressure balance between the inside and outside of the equipment.

[0045] In this embodiment, the sealing structure takes the form of a sealing ring 7, which is disposed in a groove on the upper surface of the base, such as... Figure 1 , Figure 4 , Figure 5 As shown; during the connection between the outer shell and the base, the outer shell and the sealing ring 7 are pressed together.

[0046] As an example, the connection between the outer casing and the base can be achieved by using screws.

[0047] In one embodiment, the wireless device further includes: at least two handles 8, such as Figure 8 As shown, handle 8 is located on the lower surface of the base. The handle is used to support the base, so that when the base is placed on a flat surface (such as the ground), the external interface is suspended in the air and does not contact the flat surface, thus protecting the external interface from direct impact from external forces. The handle also makes it easier for the operator to pick up and place the equipment, and it is also convenient to use the handle to hoist the equipment.

[0048] Preferably, at least two handles 8 can be set on opposite sides of the lower surface of the base, making it more convenient and stable to pick up and place the equipment.

[0049] Preferably, a waterproof sealing ring is provided between the external interface and the base, which further improves the waterproof rating of the wireless equipment and provides better outdoor protection.
