The external antenna 32 is fixedly installed on the hub frame 31, and the two ends of the signal line 35 are respectively electrically connected to the host 11 and the external antenna 32. The support frame 21 is provided with a fixed section 22, a curved section 23 and an installation section 24, and the curved section 23 is located between the fixed section 22 and the installation section 24. The host 11 is fixedly installed on the installation section 24, and the installation section 24 and the curved section 23 surround to form an installation groove for accommodating the hub frame 31. There are two curved sections 23 and two fixed sections 22 in total, and the two curved sections 23 correspond to the fixed sections 22 one by one. The two curved sections 23 are respectively located at the two ends of the mounting section 24. The curved sections 23 are provided with through grooves 26, and the through grooves 26 on the two curved sections 23 are respectively for the external antenna 32 and the signal line 35 to pass through.

[0036] The wire hub 31 is provided with a fixing hole 33, the mounting section 24 is provided with a through hole 25, the fixing hole 33 is penetrated by an expansion nail sleeve 41, the expansion nail sleeve 41 is penetrated by the through hole 25, the expansion nail sleeve 41 is provided with an expansion nail hole 42, the expansion nail sleeve 41 is provided with a notch 43 connected to the expansion nail hole 42, and the expansion nail sleeve 41 is provided with an expansion nail body 47 inserted into the expansion nail hole 42. The aperture of the fixing hole 33 is larger than the aperture of the through hole 25. The outer wall of the expansion nail sleeve 41 is provided with an external thread 44. The outer wall of the expansion nail sleeve 41 is threadedly connected with a nut 45, and the nut 45 is clamped with the side of the wire hub 31 away from the mounting section 24. The expansion nail sleeve 41 is fixedly connected with a clamping plate 46, and the clamping plate 46 is clamped with the side of the mounting section 24 away from the wire hub 31. The expansion nail body 47 is fixedly connected with a pressure plate 48. The fixing hole 33 is located at the external antenna 32, so that the fixing hole 33 and the external antenna 32 are located above the center of gravity of the hub 31, so that when the hub 31 is hung on the expansion nail sleeve 41, the external antenna 32 is located above the hub 31, so that the external antenna 32 is in a higher position with better signal.

[0037] refer to Figure 3 The host 11 is provided with a processing module 12, a data acquisition module 13 and a communication module 14. The processing module 12 is electrically connected to the data acquisition module 13 and the communication module 14 respectively. The communication module 14 is electrically connected to the external antenna 32 through a signal line 35. The data acquisition module 13 is electrically connected to the meter and is used to collect the meter reading data of the meter. The data acquisition module 13 and the meter communicate using the RS485 protocol. The processing module 12 is used to receive the meter reading data sent by the data acquisition module 13 and transmit the meter reading data to the communication module 14. The communication module 14 is used to upload the meter reading data to the host computer, receive and view the collected meter reading data through the host computer, and the communication module 14 uses the GPRS tunnel protocol or the WAN protocol for wireless data transmission.

[0038] The support frame 21 is installed at the meter, and the host 11 is connected to the meter for communication, so that the host 11 can collect meter reading data. The host 11 is electrically connected to the external antenna 32 through the signal line 35, so that the host 11 can send meter reading data through the external antenna 32, realizing the function of remote transmission of meter reading data.

[0039] This embodiment has the following advantages:

[0040] When the strength of the wireless signal received at the host 11 is good, the hub 31 is placed in the installation slot to reduce the space occupied by the self-organizing network meter reading remote transmission device. When the strength of the wireless signal received at the host 11 is weak, the hub 31 is taken out of the installation slot, the hub 31 and the external antenna 32 are moved to a position with a good wireless signal strength and fixed, and the signal line 35 is released from the hub 31 to ensure the electrical connection between the external antenna 32 and the host 11, so that the host 11 can remotely transmit the meter reading data at a position with a good signal strength through the external antenna 32, thereby achieving the advantage of stable wireless communication transmission.

[0041] When the hub 31 is installed in the installation slot, the expansion nail sleeve 41 is inserted into the fixing hole 33 and the through hole 25, so that the hub 31 can be hung on the support frame 21, which plays a role in providing support force for the hub 31. The expansion nail body 47 is inserted into the expansion nail hole 42, so that the expansion nail sleeve 41 is stretched on both sides of the notch 43 and pressed against the fixing hole 33, so that the expansion nail sleeve 41 is fixed in the fixing hole 33, which plays a role in improving the stability of the expansion nail sleeve 41.

[0042] When the hub 31 needs to be installed outside the installation slot, a hole is made on the wall where the antenna needs to be installed to allow the expansion nail sleeve 41 to be inserted. First, the expansion nail body 47 is taken out of the fixing hole 33, and then the expansion nail sleeve 41 is taken out of the fixing hole 33 and the through hole 25, and the hub 31 is moved so that the fixing hole 33 corresponds to the hole on the wall, and then the expansion nail sleeve 41 is passed through the fixing hole 33 and inserted into the hole on the wall, and then the expansion nail body 47 is reinserted into the expansion nail hole 42, and the expansion nail sleeve 41 is opened and inserted into the hole on the rack wall, and the expansion nail sleeve 41 and the hub 31 are fixed to the wall by friction, so as to achieve the function of fixing the hub 31 and the external antenna 32 outside the installation slot.

[0043] The fixing hole 33 has a relatively large diameter, which can prevent the expansion nail body 47 from being stuck by the inner wall of the fixing hole 33 when inserted into the expansion nail hole 42, thereby avoiding insufficient friction between the expansion nail sleeve 41 and the wall.

[0044] The external thread 44 contacts the wall, which can effectively increase the friction between the expansion nail sleeve 41 and the wall, thereby improving the stability between the expansion nail sleeve 41 and the wall.

[0045] The expansion nail sleeve 41 is threadedly connected to the nut 45 via the external thread 44 , so that the nut 45 can be tightened on the expansion nail sleeve 41 and the nut 45 can be clamped on the cable hub 31 , thereby improving the stability of the cable hub 31 .

[0046] The clamping connection between the clamping plate 46 and the mounting section 24 can improve the stability between the expansion nail sleeve 41 and the mounting section 24 .

[0047] By applying force on the pressure plate 48 , it is convenient to push the expansion nail body 47 into the expansion nail hole 42 .

[0048] The signal line 35 wound on the winding shaft 34 is blocked by the baffle 36 and the wire collection frame 31, so that the signal line 35 can be easily rolled up.

[0049] The two curved sections 23 and the fixed section 22 provide support force for the installation section 24 , thereby improving the structural stability of the installation section 24 .

[0050] According to the disclosure and teaching of the above specification, the technicians in the field of the utility model can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
