Description

A method and system for receiving and distributing wireless signals in a wellhead environment Technical Field

[0001] This disclosure relates to the field of power technology, specifically to a signal reception and distribution method and system based on antennaless physical technology in a wellhead environment. Background Technology

[0002] The statements in this section are merely background information relating to this disclosure and do not necessarily constitute prior art.

[0003] With the expansion of power tunnels and the construction of urban underground utility tunnels, the safety of underground spaces is becoming increasingly important. As entrances and exits to underground spaces, the safety of manhole covers is paramount. Currently, many manhole covers on the market utilize Internet of Things (IoT) communication technology for effective monitoring.

[0004] Because the size of monitoring equipment is limited and the environment is harsh in wellhead conditions, it is very difficult to use traditional antennas when considering both size and protection. Summary of the Invention

[0005] To address the aforementioned problems, this disclosure proposes a wireless signal reception and distribution method and system for wellhead environments. In the confined environment of a wellhead, an antenna-free physical technology is employed, eliminating the need for an external antenna, to achieve wireless signal transmission and reception.

[0006] According to some embodiments, the present disclosure adopts the following technical solutions:

[0007] A wireless signal receiving and distribution system for wellhead environments includes:

[0008] The controller motherboard is configured to use the PCB circuit board as a radiation source to achieve wireless signal resonance;

[0009] Antenna enhancers are configured to achieve gain and amplification of signals in different frequency bands;

[0010] The matching circuit is configured to connect to the antenna booster, and by adjusting the matching network parameters of the matching circuit, signal transmission and reception in multiple frequency bands can be achieved.

[0011] Furthermore, the antenna enhancer is located on one side of the controller motherboard.

[0012] Furthermore, the antenna enhancer is provided with multiple interfaces and connected to multiple matching circuits, and different signal frequencies are matched by adjusting the matching network connected to the antenna enhancer.

[0013] Furthermore, the matching circuit resonates with the antenna booster and the PCB circuit board to adapt to different wireless frequency bands.

[0014] Furthermore, the matching circuit consists of inductors and capacitors, and the standing wave ratio is measured using a vector network analyzer.

[0015] Furthermore, a wireless module is installed on the controller motherboard, which is connected to the antenna booster through a corresponding matching circuit.

[0016] Furthermore, the wireless module may be a GNSS module.

[0017] Furthermore, multiple wireless modules and multiple matching circuits are configured.

[0018] According to some embodiments, the present disclosure adopts the following technical solutions:

[0019] A method for receiving and distributing wireless signals in a wellhead environment, comprising:

[0020] By using the copper ground plane of the PCB circuit board itself as a radiation source, one or more miniature antenna enhancers are combined with the ground plane to balance the reactive component of the ground plane, so that the energy of wireless radiation is guided.

[0021] Furthermore, a matching circuit is added to form an antennaless form, which works in conjunction with the antenna booster. By adjusting the parameters of the matching circuit, impedance matching is achieved, and resonance is formed with the antenna booster and the ground layer to adapt to different wireless frequency bands.

[0022] Compared with the prior art, the beneficial effects of this disclosure are as follows:

[0023] This system boasts strong frequency band adaptability and high reusability. Unlike traditional antennas, its frequency is not specific and can be adjusted according to user needs, resulting in high integration. Traditional antennas have fixed frequency characteristics that cannot be adjusted, while this system can adapt to different wireless signal frequencies by adjusting the matching network. The controller motherboard may use different wireless modules, such as GNSS, Bluetooth, 4G, and 5G communication modules. By adopting this system and adjusting the matching network parameters, only the different wireless modules need to be replaced; there is no need to redesign the antenna, reducing project complexity, effectively improving design efficiency, and shortening the project cycle.

[0024] The system disclosed herein is small in size. Using one system, multiple wireless modules can transmit and receive signals. It only requires one edge of the circuit board. Furthermore, since it is integrated with the circuit board, it can be placed inside the structural shell, providing good protection and eliminating concerns about harsh environments such as high temperature, high humidity, or even water accumulation at the wellhead.

The antenna booster has a wide frequency adaptation range, from hundreds of megahertz to several gigahertz. The antenna booster is equipped with multiple interfaces and connects to multiple matching circuits. By adjusting the matching network connected to the antenna booster, different signal frequencies can be matched to achieve signal transmission and reception in multiple frequency bands.

[0040] The matching circuit is positioned between the antenna booster and the wireless device interface. Working in conjunction with the antenna booster, impedance matching is achieved by adjusting the matching circuit parameters, and resonance is formed with the antenna booster and the PCB ground plane. It is adaptable to different wireless frequency bands. The matching circuit is essentially the same as traditional antenna matching networks, following microwave engineering matching techniques.

[0041] The matching network consists of inductors and capacitors. The standing wave ratio (VSWR) is measured using a vector network analyzer, and the parameters of each component in the matching network are calculated using the Smith chart. As shown in Figure 2, the structure of the matching circuit includes a first capacitor C1, a second capacitor C2, a first inductor L1, and a second inductor L2. The matching network is not limited to the above form; different matching network configurations can be used to adapt to different PCB structures and radio frequencies.

These wireless modules can be GNSS modules, Bluetooth modules, 4G communication modules, 5G communication modules, etc., and multiple wireless modules and matching circuits are configured. Each wireless module is connected to the antenna amplifier via its respective matching circuit. By adjusting the component parameters of the matching circuits, frequency matching is achieved for different wireless modules, thereby enabling the transmission and reception of wireless signals from different modules.

Unlike traditional antenna technology, it does not require designing the antenna's structure, geometry, or other parameters; only a suitable matching network needs to be designed to achieve wireless signal transmission and reception across various frequency bands.

[0047] As shown in Figure 3, two different matching networks are set up: one for the 433M module and one for the 4G module. Figure 4 shows the structure diagram of the 433M module matching network, and Figure 5 shows the structure diagram of the 4G module matching network.

The antenna booster is placed on one side of the circuit board and connected to the two wireless modules and the circuit board via the two matching networks. The circuit board is 140mm long and 60mm wide. Through grounding and resonance with the antenna booster, the signal transceiver networks of the two wireless modules are formed. The matching networks are basically the same; different components can be replaced to achieve matching with different modules.
