Description

Technical Field

[0001] This invention relates to the field of remote meter reading technology, and in particular to a method and apparatus for improving the online rate of metering terminals. Background Technology

[0002] Currently, the main method for metering terminals to log in to the power supply website is by leasing signal transmission channels from the three major wireless network operators (China Mobile, China Telecom, and China Unicom) and using SIM cards for dial-up login. However, due to the inherent characteristics of the operators' technology and economic issues, there are certain wireless signal coverage blind spots during the process of metering terminals logging into the power supply website. This is especially true in unified construction communities with a high concentration of low-voltage users, where substations are often located underground, and the locations where metering terminals are placed are basically wireless signal coverage blind spots. As a result, the network requirements for remote meter reading cannot be met, causing metering terminals placed in signal blind spots to go offline. Consequently, the metering terminals cannot upload the collected user electricity consumption data to the power supply website, resulting in missing user electricity consumption data.

[0003] Currently, with the increasing number and scale of unified construction communities, the number of metering terminals is also increasing. Therefore, ensuring network signal coverage for metering terminals in the power distribution rooms of unified construction communities is crucial. Furthermore, although wireless signal coverage is the responsibility of operators, the increasing number and scale of unified construction communities lead to a growing number of wireless signal blind spots that operators need to address. Due to economic considerations and construction difficulties, operators may experience gaps in their efforts to address wireless signal coverage, thus affecting the ability of the wireless network to meet the network requirements for remote meter reading by metering terminals.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0049] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0050] Figure 1 This is a flowchart illustrating a method for improving the online rate of a metering terminal according to an embodiment of the present invention. This embodiment is applicable to situations where the metering terminal is in a wireless signal blind spot. The method can be executed by a device for improving the online rate of the metering terminal, which can be implemented using hardware and / or software methods. The method specifically includes the following steps:

[0051] S110. Determine the wireless signal coverage area of ​​the signal transceiver equipment.

[0052] Signal transceiver devices include wireless routers, wireless switches, smartphones, computers, tablets, and other devices with signal bridging capabilities. The wireless signal coverage range of a signal transceiver device refers to the area where its emitted wireless signal can be transmitted or where it can receive wireless signals. Determining the wireless signal coverage range of a signal transceiver device facilitates the subsequent determination of the installation location for devices that extend the wireless signal transmission distance.

[0053] S120. Based on the wireless signal coverage of the signal transceiver and the signal transmission range of the relay pair, a relay pair is set up between the signal transceiver and the metering terminal so that the signal transceiver can communicate with the metering terminal through the relay pair.

[0054] Specifically, a relay pair is a device capable of transmitting and receiving wireless signals, extending the range of wireless signal transmission. The signal transmission range of a relay pair refers to the area where the wireless signals emitted by the relay pair can be transmitted or the area where the relay pair can receive wireless signals. Based on the wireless signal coverage of the transceiver equipment, the relay pair can be placed within the wireless signal coverage area of ​​the transceiver equipment close to the metering terminal. Based on the signal transmission range of the relay pair, it can be determined whether the metering terminal will be within the signal transmission range of the relay pair, and the number of relay pairs to be placed between the transceiver equipment and the metering terminal can be determined based on whether the metering terminal is within the signal transmission range of the relay pair. In addition, if the number of relay pairs is greater than 2, the next relay pair extending the wireless signal transmission range can be set within the signal transmission range of the previous relay pair, close to the metering terminal, based on the signal transmission range of the relay pair. This continues until the metering terminal is within the signal transmission range of the relay pair, so that the signal transceiver can communicate with the metering terminal through the relay pair. This allows the metering terminal to transmit the user's electricity consumption data to the signal transceiver, which in turn transmits the user's electricity consumption data to the power supply network, enabling remote meter reading by the metering terminal.

[0055] This invention, by determining the wireless signal coverage range of the signal transceiver, facilitates the subsequent determination of the installation location for devices extending the wireless signal transmission distance. Based on the wireless signal coverage range of the signal transceiver and the signal transmission range of the relay pair, the relay pair is positioned within the wireless signal coverage range of the signal transceiver near the metering terminal, and the metering terminal is positioned within the signal transmission range of the relay pair. This allows the signal transceiver to communicate with the metering terminal through the relay pair, enabling the metering terminal to transmit user electricity consumption data to the signal transceiver, which in turn transmits the user electricity consumption data to the power supply network. In summary, this solution can guarantee the network requirements of the metering terminal without construction, thereby improving the online rate of the metering terminal and enabling remote meter reading.

[0056] For example, Figure 2 This is a flowchart illustrating a method for determining the wireless signal coverage area of ​​a signal transceiver device according to an embodiment of the present invention. Based on the above embodiment, the steps of the method for determining the wireless signal coverage area of ​​a signal transceiver device are further described in detail:

[0057] S210. Calculate the propagation path of the signal transceiver based on its operating parameters.

[0058] Optionally, the operating parameters include: minimum receive level, maximum transmit power, transmit antenna gain, receive antenna gain, and attenuation factor.

[0059] Specifically, the minimum receive level of a signal transceiver refers to the minimum signal level that the transceiver must achieve to transmit or receive signals that can access a network; in other words, the receiving sensitivity of the transceiver. The maximum transmit power of a signal transceiver refers to the power of its radio frequency unit's wireless transmission. The transmit power determines the strength and distance of the transmitted wireless signal; the higher the transmit power, the stronger the transmitted signal and the farther the transmission distance. The transmit antenna gain of a signal transceiver is the ratio of the power density of the signal produced by an actual antenna and an ideal radiating element at the same point in space, under the condition of equal input power. It quantitatively describes the degree to which the antenna concentrates the radiated input power. The receive antenna gain of a signal transceiver is the ratio of the power density of the signal received by an actual antenna and an ideal receiving element at the same point in space, under the condition of equal input power. It quantitatively describes the degree to which the antenna concentrates the received power. The attenuation factor of a signal transceiver refers to the measure of attenuation of the transmitted or received signal during transmission. Specifically, the attenuation factor is the ratio of the incident signal flux to the signal flux density at the receiving point, or the ratio of the outgoing signal flux to the signal flux density at the transmitting point.

[0060] In addition, based on the operating parameters of the signal transceiver equipment, the specific operating status of the signal transceiver equipment can be obtained. By using the minimum receiving level, maximum transmitting power, transmitting antenna gain, receiving antenna gain, and attenuation factor of the signal transceiver equipment during operation, the propagation path of the signal transceiver equipment can be accurately calculated.

[0061] S220. Determine the wireless signal coverage area of ​​the signal transceiver based on its coordinates and propagation path.

[0062] Since the signal is transmitted in all directions, the wireless signal coverage area of ​​the signal transceiver can be determined to be a circle.

[0063] For example, a circle is drawn with the coordinates of the signal transceiver as the center and the propagation path as the radius to obtain the wireless signal coverage of the signal transceiver.

[0064] In summary, through the above processing, the wireless signal coverage range of the signal transceiver can be accurately determined based on its operating parameters, providing a basis for subsequently determining the location of devices that extend the wireless signal transmission distance.

[0065] For example, Figure 3 This is a flowchart illustrating a method for calculating the propagation path of a signal transceiver device according to an embodiment of the present invention. Based on the above embodiment, the steps of the method for calculating the propagation path of a signal transceiver device are further described in detail:

[0066] S310. Calculate the path loss based on the minimum received level, maximum transmitted power, transmit antenna gain, and receive antenna gain.

[0067] Specifically, path loss = maximum transmit power + transmit antenna gain + receive antenna gain - minimum receive level, i.e., Pl(dB) = Pt(dB) + Gt(dB) - Pr(dB) + Gr(dB), where Pl(dB) represents path loss, Pt(dB) represents maximum transmit power, Gt(dB) represents transmit antenna gain, Pr(dB) represents minimum receive level, and Gr(dB) represents receive antenna gain.

[0068] S320. Calculate the propagation path based on path loss and attenuation factor.

[0069] The propagation path refers to the signal propagation distance of the transceiver equipment, which is also the signal coverage radius of the transceiver equipment. The attenuation factor is a measure of the attenuation of the transmitted or received signal during transmission. The value of the attenuation factor varies in different wireless environments. For example, in free space, path attenuation is proportional to the square of the distance, i.e., the attenuation factor is 2; inside buildings, the impact of distance on path loss is significantly greater than in free space. For fully open environments, the attenuation factor ranges from 2.0 to 2.5; for semi-open environments, it ranges from 2.5 to 3.0; and for relatively enclosed environments, it ranges from 3.0 to 3.5.

[0070] Specifically, propagation loss is calculated based on the attenuation factor model, where the attenuation factor model is Pl(dB) = 46 + 10*n*Log D(m), Pl(dB) represents path loss, n represents the attenuation factor, and D represents the propagation path. Substituting the path loss and attenuation factor into the above formula, the propagation path can be calculated.

[0071] For example, if the transmitting antenna gain and receiving antenna gain of the signal receiving device are zero, the transmitting power is 16.2 dBm (41 mW), the network card's receiving sensitivity (minimum receiving level) is -75 dBm, and the attenuation factor is 3.0, then based on the minimum receiving level, maximum transmitting power, transmitting antenna gain, and receiving antenna gain, the path loss Pl (dB) is calculated to be 91.2 (dB). Based on the path loss and attenuation factor, the propagation path D is calculated to be 31.6 (m).

[0072] For example, Figure 4 This is a flowchart illustrating a method for setting up a relay device pair between a signal transceiver device and a metering terminal according to an embodiment of the present invention. Based on the above embodiment, the steps of the method for setting up a relay device pair between the signal transceiver device and the metering terminal are further described in detail:

[0073] S410. Determine the number of relay pairs based on the coordinates of the signal transceiver, the wireless signal coverage of the signal transceiver, the coordinates of the metering terminal, and the maximum communication distance of the relay pair.

[0074] Specifically, the exact location of the signal transceiver can be determined from its coordinates, and the exact location of the metering terminal can be determined from its coordinates. Therefore, the distance between the signal transceiver and the metering terminal can be calculated based on their respective coordinates. The signal coverage radius of the signal transceiver can be determined from its wireless signal coverage range. Since the signal transceiver needs to communicate with the metering terminal through relay devices, the sum of the signal coverage radius of the signal transceiver and the maximum communication distance of multiple relay devices is greater than or equal to the distance between the signal transceiver and the metering terminal. Therefore, the number of relay devices can be determined using the distance between the signal transceiver and the metering terminal, the signal coverage radius of the signal transceiver, and the maximum communication distance of a single relay device pair.

[0075] S420. Based on the number of relay pairs, the coordinates of the signal transceivers, the wireless signal coverage of the signal transceivers, the maximum communication distance of the relay pairs, and the coordinates of the metering terminal, determine the coordinates of each relay pair.

[0076] For example, Figure 5 This is a schematic diagram of the location of a relay device provided in an embodiment of the present invention. Figure 6 This is a schematic diagram illustrating the location of another relay device provided in an embodiment of the present invention. Figures 5-6 As shown, if the number of relay devices 02 is 1, the coordinates of the signal transceiver 01 are (0, 0), the coverage radius of the wireless signal coverage area of ​​the signal transceiver 01 is 3, the maximum communication distance of the relay devices 02 is 4, and the coordinates of the metering terminal 03 are (0, 10), then the coordinates of the relay devices 02 can be (0, x), and the range of x is 6 ≤ x ≤ 7.

[0077] S430. Set up the relay device pair according to the coordinates of the relay device pair.

[0078] S440. Connect the signal transceiver to the relay equipment for communication, and connect the relay equipment to the metering terminal for communication.

[0079] Optionally, the relay equipment pair includes a relay front-end equipment and a relay back-end equipment.

[0080] The relay front-end equipment includes a network signal extender, and the relay back-end equipment includes a wireless analog transmitter. The relay front-end equipment receives Ethernet data sent by the signal transceiver as a digital signal, then modulates it into an analog signal and transmits it to the corresponding relay back-end equipment. The relay back-end equipment can interact with the metering terminal or the relay front-end equipment by transmitting and receiving analog signals. The relay back-end equipment can send received meter reading data to the relay front-end equipment as an analog signal, and the relay front-end equipment can demodulate the analog signal into a digital signal and transmit it to the signal transceiver.

[0081] For example, Figure 7 This is a flowchart illustrating a method for determining the coordinates of each relay front-end device and each relay back-end device according to an embodiment of the present invention. Based on the above embodiment, the steps of the method for determining the coordinates of each relay front-end device and each relay back-end device are further detailed as follows:

[0082] S510. Based on the coordinates of the signal transceiver equipment and the metering terminal, determine the setting direction of the relay front-end equipment and the relay back-end equipment, and record it as the first direction.

[0083] Specifically, the direction in which the coordinates of the signal transceiver point to the coordinates of the metering terminal is the first direction. This first direction minimizes the number of relay front-end and relay back-end devices required.

[0084] S520. Along the first direction, determine the coordinates of each relay front-end device and each relay back-end device based on the wireless signal coverage of the signal transceiver device, the maximum communication distance of the relay front-end device, and the maximum communication distance of the relay back-end device.

[0085] For example, Figure 8 This is a schematic diagram illustrating the location of a relay front-end device and a relay back-end device according to an embodiment of the present invention, as shown below. Figure 8 As shown, if the number of relay front-end devices 021 is 1, the number of relay back-end devices 022 is 1, the coordinates of the signal transceiver device 01 are (0, 0), the coverage radius of the wireless signal coverage area of ​​the signal transceiver device 01 is 3, the maximum communication distance of the relay front-end device 021 is 2, the maximum communication distance of the relay back-end device 022 is 2, and the coordinates of the metering terminal 03 are (0, 10), then the coordinates of the relay front-end device 021 can be (0, 5), and the coordinates of the relay back-end device 022 can be (0, 9).

[0086] Optionally, connecting the signal transceiver to the relay device includes connecting the signal transceiver to the relay front-end device.

[0087] The relay front-end device can receive Ethernet data sent by the signal transceiver as a digital signal. Before the signal transceiver and the relay front-end device can communicate, a communication connection needs to be established between them.

[0088] Optionally, connecting the relay equipment to the metering terminal includes: connecting the relay back-end equipment to the metering terminal or the relay front-end equipment.

[0089] The relay back-end equipment can interact with the metering terminal or relay front-end equipment by transmitting and receiving analog signals. Before the relay back-end equipment can communicate with the metering terminal or relay front-end equipment, a communication connection needs to be established between the relay back-end equipment and the metering terminal or relay front-end equipment.

[0091] The range determination module 810 is used to determine the wireless signal coverage range of the signal transceiver device;

[0093] In this embodiment of the invention, the range determination module 810 determines the wireless signal coverage range of the signal transceiver, facilitating the subsequent determination of the installation location for devices extending the wireless signal transmission distance. The relay device pair setting module, based on the wireless signal coverage range of the signal transceiver and the signal transmission range of the relay device pair, places the relay device pair within the wireless signal coverage range of the signal transceiver near the metering terminal, and places the metering terminal within the signal transmission range of the relay device pair. This allows the signal transceiver to communicate with the metering terminal through the relay device pair, enabling the metering terminal to transmit user electricity consumption data to the signal transceiver, which in turn transmits the user electricity consumption data to the power supply network.
