Description

Technical Field

[0001] The present invention relates to the technical field of data transmission, and in particular, to a method, system, device and electronic device for transmitting device data. Background Art

[0002] Currently, in the process of data transmission, especially in the process of transmitting device data (such as meter reading data) for power equipment (such as smart meters), it mainly relies on high-speed power line carrier communication or micro-power wireless communication. High-speed power line carrier communication is easily affected by power line noise and impedance changes, thus affecting the stability and effectiveness of device data transmission. Micro-power wireless communication is easily blocked by obstacles (such as buildings, trees, etc.), resulting in a decline in the quality of the transmitted signal and the failure of meter reading data transmission. And the network capacity of micro-power wireless communication is limited. When the number of power equipment is too large, it may cause network congestion, affecting the transmission efficiency and reliability of meter reading data.

[0033] Embodiment 1

[0034] According to an embodiment of the present invention, an embodiment of a method for transmitting device data is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0035] Figure 1 is a flowchart of a method for transmitting device data according to an embodiment of the present invention, applied to a data transmission system. The data transmission system includes a collector, a concentrator, and a master station, as Figure 1 shown. The method includes the following steps:

[0036] Step S102, obtain the device data of the target power device.

[0037] In the technical solution provided in step S102 of the embodiment of the present invention above, the target power device can be a power device that needs to upload device data to the master station for storage, and can be an electric meter, for example, a smart meter. If a certain power device needs to transmit device data to the master station for storage, then this power device can be called a target power device, and the collector in the data transmission system can be connected to the target power device to obtain the device data. Among them, the collector can also be deployed on the target power device. The device data can be used to represent the operating state and / or operating performance of the corresponding power device during operation. The device data can include key parameters such as the operating state of the power device, environmental conditions, signal quality, and energy consumption. If the power device is a smart meter, the corresponding device data can be meter reading data.

[0038] In this embodiment, by obtaining the device data in the target power device, the operating state and communication environment of the target power device can be comprehensively mastered, providing a basis for subsequent transmission of the device data.

[0039] Optionally, the device data can be obtained through the collector. The collector can be made into a module composed of a plastic shell, a printed circuit board (PCB for short), and a corresponding standard interface according to certain standards, and the collector can be deployed on the smart meter in a hot-swappable manner. The collector can be used to automatically or on-demand read the device data inside the smart meter, such as power consumption, voltage, current, etc. The above-mentioned method for obtaining the device data and the specific content are only for illustrative purposes and are not specifically limited here.

[0040] Step S104, based on the device data, detect the communication policy set of the target power device to obtain the target communication policy.

[0041] In the technical solution provided in step S104 of the embodiment of the present invention, after obtaining the device data of the target power device, the communication policy set of the target power device can be detected based on the device data to obtain the target communication policy. The communication policy set can include at least one communication policy, and the target communication policy can be used to represent the communication policy with the maximum performance index in the communication policy set. The performance index can be used to represent the transmission performance of the collector to transmit the device data to the concentrator.

[0042] In this embodiment, the communication policy set can include various communication policies, which can be a combination obtained from various communication policies. For example, high-speed power line carrier communication, 230MHz power wireless private network communication, micro-power wireless communication, etc. The performance index can comprehensively reflect the advantages and disadvantages of the communication policy and is the key basis for selecting the target communication policy.

[0043] Optionally, each communication policy has corresponding configuration parameters, such as frequency, power, modulation method, coding method, etc. The communication policy set can be constructed according to the characteristics of various communication policies, the network environment, and the specific requirements of the power device. The performance index can include transmission rate, signal strength, bit error rate, response time, energy consumption efficiency, data integrity, and security, etc. The specific content of the above performance index is only for illustration and is not specifically limited here.

[0044] Optionally, selecting the communication policy with the maximum performance index from the communication policy set as the target communication policy can ensure the transmission efficiency and quality of device data while meeting the flexibility requirements for device data transmission in a specific environment. For example, in a power line environment with severe interference, 230MHz power wireless private network communication can be preferentially selected. When transmitting short-distance high-speed device data, high-speed power line carrier communication can be preferentially selected. When transmitting short-distance low-energy-consuming device data, micro-power wireless communication can be preferentially selected. This is only for illustration and is not specifically limited here.

[0045] Optionally, when a certain communication policy fails or needs to be maintained temporarily, by automatically switching to other communication policies, fast fault recovery can be achieved. At the same time, dynamic communication policy selection helps in the management of the data transmission system, such as fault detection, device configuration, and network optimization, to ensure the efficient operation of the power communication network.

[0046] In the embodiment of the present invention, based on the device data, by detecting the communication policy set, it is identified which communication policy can provide the maximum performance index in the current environment, and the communication policy with the maximum performance index is selected from the communication policy set as the target communication policy. That is, the transmission performance of the collector to transmit the device data to the concentrator most meets the current requirements, thereby ensuring that the device data can be transmitted flexibly and efficiently in the current environment.

[0047] Step S106: Control the collector to transmit the device data to the concentrator according to the target communication policy.

[0048] In the technical solution provided in step S106 of the embodiment of the present invention, after detecting the communication policy set of the target power device based on the device data to obtain the target communication policy, the collector can be controlled to transmit the device data to the concentrator according to the target communication policy. The concentrator, also known as the data concentrator or the electric energy metering data collector, is used to receive the device data from multiple collectors. The collector can be located on the side of the smart meter and can be connected to the smart meter in a hot-pluggable manner or in other ways.

[0049] In this embodiment, the target communication policy is a communication method and its parameters that meet the requirements selected by analyzing the device data and the current network environment. That is, transmitting the device data according to the target communication policy can maximize the utilization of the currently available communication resources and improve the rate, stability, and reliability of the device data transmission. For example, in an environment where the power line carrier communication signal is weak, switching to the 230MHz power wireless private network communication can avoid signal attenuation and ensure the accurate and efficient transmission of the device data.

[0050] Optionally, due to the complex and changeable power system environment, including but not limited to power line noise, wireless signal occlusion, weather conditions, etc. The target communication policy can be dynamically adjusted according to the real-time detected environmental changes to select the most suitable communication policy for the current conditions, thereby effectively coping with environmental interference and ensuring the continuity and efficiency of the device data transmission.

[0051] Step S108: Control the concentrator to transmit the received device data to the master control station.

[0052] In the technical solution provided in step S108 of the embodiment of the present invention, after controlling the collector to transmit the device data to the concentrator according to the target communication policy, the concentrator can be controlled to transmit the received device data to the master control station. The master control station can also be called the system master station.

[0053] In this embodiment, the device data interaction between the system master station and the concentrator can be completed through the 230MHz power wireless private network. If the data transmission system needs to query the device data of a certain power device, the system master station can send a device data query instruction to the concentrator to query the device data and receive, store, and process the device data uploaded by the concentrator.

[0054] Optionally, the device data is transmitted through a concentrator, which reduces the direct communication requirements between the master station and each collector and shortens the path of device data transmission. This not only speeds up the transmission of device data but also reduces the energy consumption during communication and improves the efficiency of the communication network of the entire power system.

[0055] Optionally, the system master station receives the meter reading data uploaded through the 230 MHz dedicated power wireless network and stores the meter reading data for subsequent analysis and use. After receiving the meter reading data, the system master station can perform data processing, such as data cleaning, format conversion, preliminary analysis, etc. Based on the collected meter reading data, advanced data analysis and decision-making, such as load forecasting, power demand management, and operation strategy optimization of virtual power plants, can be carried out.

[0056] In steps S102 to S108 of the embodiment of the present invention, if it is necessary to transmit device data, the device data of the target power device can be obtained; based on the device data, the communication strategy set of the target power device can be detected to obtain the target communication strategy, where the communication strategy set includes at least one communication strategy, and the target communication strategy is used to represent the communication strategy with the largest performance index in the communication strategy set, and the performance index is used to represent the transmission performance of the collector transmitting device data to the concentrator; the collector can be controlled to transmit the device data to the concentrator according to the target communication strategy; the concentrator can be controlled to transmit the received device data to the master station. In the embodiment of the present invention, in response to obtaining the device data of the target power device, for the performance indexes of multiple communication strategies in the communication strategy set, the communication strategy with the largest performance index is selected as the target communication strategy for transmitting device data. This ensures the high reliability and real-time nature of device data transmission, overcomes the limitation that a single communication strategy cannot flexibly adopt the target communication strategy to efficiently transmit device data in the face of a complex and changeable power environment, thereby solving the technical problem of low data transmission efficiency and achieving the technical effect of improving data transmission efficiency.

[0057] The embodiments of the present invention will be described in detail below in combination with the above steps.

[0058] As an optional embodiment, step S104, detecting the communication strategy set of the target power device based on the device data to obtain the target communication strategy, includes: in response to obtaining the device data of the target power device, detecting the communication strategy set to obtain a first detection result, where the first detection result is used to represent whether the performance index of transmitting device data according to the corresponding communication strategy is greater than the performance index threshold; based on the first detection result, determining the target communication strategy from the communication strategies.

[0059] In this embodiment, since the device data includes key parameters such as the operating status, environmental conditions, signal quality, and energy consumption of the power device, it can provide basic information for the subsequent detection of the communication policy set. In the process of detecting the communication policy set of the target power device based on the device data to obtain the target communication policy, the communication policy set can be detected to obtain the first detection result when the device data of the target power device is acquired; the target communication policy can be determined from the communication policy set based on the first detection result, where the first detection result can be used to indicate whether the performance index of transmitting device data according to the corresponding communication policy is greater than the performance index threshold.

[0060] Optionally, each communication policy in the communication policy set can be a set of rules that define data transmission parameters and technologies. For example, using high-speed power line carrier, 230MHz power wireless private network, or micro-power wireless communication, etc. By detecting the performance indexes of each communication policy in the current environment, such as transmission rate, signal strength, bit error rate, delay time, etc. Compare the performance index with the performance index threshold. For example, if the performance index of a communication policy is higher than the performance index threshold, it indicates that the communication policy can provide high-quality device data transmission services under the current conditions; otherwise, it may indicate that the transmission performance of the communication policy is poor and may not be suitable for the current communication requirements.

[0061] As an optional embodiment, determining the target communication policy from the communication policies based on the first detection result includes: in response to there being an initial communication policy in the communication policy set, determining the initial communication policy as the target communication policy, where the initial communication policy is the communication policy in the communication policy set whose performance index is greater than the performance index threshold; in response to there being at least two initial communication policies in the communication policy set, determining the initial communication policy with the largest performance index among the at least two initial communication policies as the target communication policy.

[0062] In this embodiment, after obtaining the first detection result, the target communication policy can be determined from the communication policies. If there is an initial communication policy in the communication policy set and the performance index of the initial communication policy is greater than the performance index threshold, the initial communication policy can be determined as the target communication policy. If there are at least two initial communication policies in the communication policy set, the initial communication policy with the largest performance index among the at least two initial communication policies can be compared and determined as the target communication policy.

[0063] Optionally, when the performance metrics of at least two communication policies exceed the performance metric threshold, the performance metrics of these initial communication policies can be further compared to find the communication policy with the largest performance metric. The larger the performance metric, the better the transmission effect that can be provided by using this communication policy for device data transmission under the current network environment and device conditions, such as the highest transmission efficiency, the lowest transmission error, and the shortest delay time.

[0064] As an alternative embodiment, the collector includes communication components, the number of communication components being the same as the number of communication policies. The communication components are used to execute the corresponding communication policies. In response to obtaining the device data of the target power device, the communication policy set is detected to obtain a first detection result, including: in response to obtaining the device data of the target power device, the communication policy set is detected to obtain a second detection result, where the second detection result is used to represent the connection status between the concentrator and the communication components corresponding to the communication policies in the communication policy set; based on the second detection result, the first detection result is determined.

[0065] In this embodiment, the collector may include communication components, the number of communication components being the same as the number of communication policies, and the communication components may be used to execute the corresponding communication policies. In the process of obtaining the device data of the target power device and detecting the communication policy set to obtain a first detection result, the communication policy set may be detected to obtain a second detection result when the device data of the target power device is obtained; the first detection result may be determined based on the second detection result. Among them, the second detection result may be used to represent the connection status between the concentrator and the communication components corresponding to the communication policies in the communication policy set. For example, normal connection, abnormal connection.

[0066] Optionally, if the communication policy set includes a 230 MHz power wireless private network communication policy and a high-speed power line carrier communication policy, then the collector will be equipped with corresponding 230 MHz power wireless private network communication components and high-speed power line carrier communication components.

[0067] Optionally, when the communication components are 230 MHz power wireless private network communication and high-speed power line carrier communication components, the concentrator can monitor the dual-mode meter reading channels where the communication components are located. Whichever channel can establish a normal connection with the concentrator, the concentrator will read, store, and process the meter reading data uploaded by that channel. If both channels can establish a normal connection with the concentrator, then according to a certain rule protocol, only the data uploaded by one of the channels will be read, stored, and processed.

[0068] As an alternative embodiment, determining the first detection result based on the second detection result includes: in response to the second detection result indicating that the connection status is normal, determining that the first detection result corresponding to the communication policy is that the performance index is greater than the performance index threshold; in response to the second detection result indicating that the connection status is abnormal, determining that the first detection result corresponding to the communication policy is that the performance index is less than or equal to the performance index threshold.

[0069] In this embodiment, in the process of determining the first detection result based on the second detection result, when the second detection result indicates that the connection status is normal, it can be determined that the first detection result corresponding to the communication policy is that the performance index is greater than the performance index threshold; when the second detection result indicates that the connection status is abnormal, it can be determined that the first detection result corresponding to the communication policy is that the performance index is less than or equal to the performance index threshold.

[0070] Optionally, if the second detection result indicates that the connection status is normal, that is, the communication link is stable, the signal quality is good, the bit error rate is low, etc., it means that it is feasible to use this communication policy for device data transmission. At this time, it can be determined that the first detection result corresponding to this communication policy is that the performance index is greater than the performance index threshold, indicating that the current communication policy meets the basic requirements for efficient and stable device data transmission.

[0071] Optionally, if the second detection result indicates that the connection status is abnormal, such as the communication link is unstable, the signal quality is poor, the bit error rate is high or the connection cannot be established at all, etc., it means that there are risks or it is impossible to use this communication policy for device data transmission. In this case, it can be determined that the first detection result corresponding to this communication policy is that the performance index is less than or equal to the performance index threshold, indicating that the current communication policy does not meet the basic conditions for data transmission.

[0072] Optionally, by selecting and adjusting the most suitable communication policy, according to real-time device data and network conditions, the efficient, stable and secure transmission of device data can be ensured.

[0073] As an alternative embodiment, the concentrator includes a directional tracking circularly polarized antenna. After controlling the concentrator to transmit the received device data to the master station, the method further includes: in response to the working mode of the data transmission system switching from the operating mode to the idle mode and there being a next power device of the target power device among the power devices concentrated, switching the working mode from the idle mode to the operating mode; in the operating mode, adjusting the pointing of the radiation pattern of the directional tracking circularly polarized antenna to obtain an adjustment result; in response to the adjustment result being that the pointing of the radiation pattern of the directional tracking circularly polarized antenna is adjusted to the direction where the next power device is located, acquiring the device data of the next power device.

[0074] In this embodiment, the 230 MHz power wireless communication component on the concentrator side may adopt a directional tracking circularly polarized antenna. After the control concentrator transmits the received device data to the master station and completes a round of device data transmission, the working mode of the data transmission system may be switched from the operating mode to the idle mode. That is to say, there is currently no device data transmission task and it is in the standby state to save energy and reduce unnecessary communication activities. In the idle mode, the concentrator may check whether there is a next power device in the power device set that needs to perform device data transmission. If it exists, it means that it is necessary to prepare to receive and process the device data of the next power device, and the concentrator will switch the working mode from the idle mode back to the operating mode. That is to say, it enters the active state again and is ready to perform device data transmission. In the operating mode, the concentrator controls the directional tracking circularly polarized antenna equipped with it, adjusts the pointing of the radiation pattern of the directional tracking circularly polarized antenna, points the radiation pattern of the directional tracking circularly polarized antenna in the direction where the next power device is located, and the concentrator will obtain the device data of the next power device.

[0075] Optionally, the circularly polarized wave has the characteristic of orthogonality of the sense of rotation, that is, when the circularly polarized wave is reflected when encountering an obstacle during transmission, the sense of rotation of its reflected wave is reversed (if the incident wave is right-handed circularly polarized, the reflected wave is left-handed circularly polarized; conversely, if the incident wave is left-handed circularly polarized, the reflected wave is right-handed circularly polarized). Therefore, when the sense of rotation of the electromagnetic wave reflected by buildings, woods, hills, water surfaces, etc. is reversed, the above-mentioned reflected wave will not cancel the field strength of the incident wave at the receiving end, and the reflected wave will not be received by the circularly polarized antenna at the receiving end. Compared with the current conventional linearly polarized antenna, using a circularly polarized antenna can avoid clutter and multipath interference, enhance the anti-interference ability, and improve the reliability of the meter reading data transmission.

[0076] Optionally, the directional tracking circularly polarized antenna can be composed of a directional circularly polarized antenna and a servo turntable. The directional circularly polarized antenna can adopt a circularly polarized microstrip antenna. The directional antenna has the advantages of high gain and strong directivity, which can improve the quality of the received signal and enhance the reliability and stability when the meter reading data is transmitted from the collector end to the concentrator through the 230 MHz power wireless private network. The directional circularly polarized antenna can be mounted on a flat plate, and the flat plate can be fixed on the servo turntable. A Global Positioning System (GPS) positioning device and an electronic compass can be installed on the servo turntable. According to the longitude and latitude information of the smart meter provided by the GPS positioning device on the smart meter side, the servo turntable enables the GPS data guiding function, and the servo turntable drives the flat plate to rotate synchronously. When the radiation pattern of the directional circularly polarized antenna points to the target power device, the pose of the servo turntable is automatically locked. When it is necessary to collect the electrical energy information of the next power device, the servo turntable drives the flat plate to rotate so that the radiation pattern of the directional circularly polarized antenna points to the target power device at that moment. Thus, it is possible to collect the electrical energy information of multiple smart meters (such as charging piles) distributed in different areas, improving the collection efficiency.

[0077] In an embodiment of the present invention, if it is necessary to transmit device data, the device data of the target power device can be obtained; based on the device data, the communication strategy set of the target power device can be detected to obtain the target communication strategy. The communication strategy set includes at least one communication strategy, and the target communication strategy is used to represent the communication strategy with the maximum performance index in the communication strategy set. The performance index is used to represent the transmission performance of the collector transmitting the device data to the concentrator; the collector can be controlled to transmit the device data to the concentrator according to the target communication strategy; the concentrator can be controlled to transmit the received device data to the master station. In an embodiment of the present invention, in response to obtaining the device data of the target power device, for the performance indexes of multiple communication strategies in the communication strategy set, the communication strategy with the maximum performance index is selected as the target communication strategy for transmitting the device data. This ensures the high reliability and real-time nature of the device data transmission, overcomes the limitation that a single communication strategy cannot flexibly adopt the target communication strategy to efficiently transmit device data in the face of a complex and changeable power environment, thereby solving the technical problem of low data transmission efficiency and achieving the technical effect of improving the data transmission efficiency.

[0078] Embodiment 2

[0079] The following is a detailed description in combination with another alternative specific implementation manner.

[0080] At present, with the large-scale popularization of smart meters, it is crucial to improve the reading and transmission capabilities of the power consumption data of smart meters to meet the coordinated control technical requirements of load forecasting and rapid response of virtual power plants. Most distribution substations adopt pure high-speed power line carrier (High Speed Power Line Carrier, abbreviated as HPLC) or pure micro-power wireless (Radio Frequency, abbreviated as RF) meter reading methods. Due to complex noise interference and variable channel impedance in high-speed power line carrier communication, there are "dead corners" in meter reading, and it is impossible to achieve a 100% reading success rate. Micro-power wireless communication is also affected by signal occlusion and attenuation caused by surrounding obstacles, and there are also "dead corners" in meter reading and it is impossible to achieve a 100% reading success rate. Therefore, pure high-speed power line carrier communication or pure micro-power wireless communication cannot meet the high-reliability and high-real-time transmission requirements of virtual power plants for meter reading data.

[0081] In related technologies, the concentrator uploads the meter reading data to the system master station in the background through 3G / 4G / 5G wireless public networks, General Packet Radio Service (abbreviated as GPRS) or optical fibers. However, wireless public networks have deficiencies such as complex construction projects, high costs, unguaranteed timeliness, low acquisition success rates, poor networking flexibility, high long-term usage costs, and information security risks, and cannot meet the high-reliability and high-real-time requirements of virtual power plants for meter reading data. The large-scale deployment of optical fibers consumes a large amount of manpower and material resources, and for areas such as remote mountain villages and islands, the deployment of optical fibers is difficult and costly. In addition, in the event of natural disasters, optical fibers are also prone to failure, resulting in power communication interruption. Therefore, there is still the technical problem of low data transmission efficiency.

[0082] The present invention proposes a meter reading data transmission method for virtual power plants. This method adopts dual-mode communication technology, omnidirectional circularly polarized antenna and directional tracking circularly polarized antenna technology, as well as 230MHz power wireless private network technology to solve the drawbacks of unguaranteed network reliability and real-time performance and unstable signals existing in the process of transmitting meter reading data to the system master station at present, so as to meet the functional requirements of accurate load forecasting and real-time coordinated control of virtual power plants. It solves the technical problem of low data transmission efficiency and achieves the technical effect of improving data transmission efficiency.

[0083] The following is a further introduction to this method.

[0084] In this embodiment, Figure 2 is a schematic diagram of the structure diagram of a meter reading data transmission system according to an embodiment of the present invention, as Figure 2As shown in the figure, the meter reading data transmission system may include: smart meter 201, collector 202, smart meter 203, collector 204, 230MHz power wireless + high-speed power line carrier dual-mode module 205, 230MHz power wireless + high-speed power line carrier dual-mode module 206, 230MHz power wireless + high-speed power line carrier dual-mode module 207, concentrator 208, 230MHz power wireless private network 209, and system master station 210.

[0085] Smart meter 201 can communicate with collector 202 through a data interface and a communication protocol. Smart meter 203 can communicate with collector 204 through a data interface and a communication protocol.

[0086] Collectors 202 and 204 can communicate with 230MHz power wireless + high-speed power line carrier dual-mode modules 205 and 206 respectively through a data interface and a communication protocol. Collectors 202 and 204 can transmit the meter reading data to concentrator 208 through a dual-mode communication method (230MHz power wireless private network communication and high-speed power line carrier communication). For the convenience of large-scale application, collectors 202 and 204 can be made into modules composed of a plastic shell, a PCB, and corresponding standard interfaces according to certain standards, and can be installed on smart meters 201 and 203 in a hot-swappable manner.

[0087] 230MHz power wireless + high-speed power line carrier dual-mode modules 205 and 206, 230MHz power wireless + high-speed power line carrier dual-mode module 205 and 230MHz power wireless + high-speed power line carrier dual-mode module 206 are respectively on the sides of smart meters 201 and 203, and can include a 230MHz wireless communication unit. The 230MHz wireless communication units on the sides of smart meters 201 and 203 can use omnidirectional circularly polarized antennas.

[0088] 230MHz Power Wireless + High-Speed Power Line Carrier Dual-Mode Module 207. The 230MHz power wireless + high-speed power line carrier dual-mode module 207 is on the concentrator 208 side and can include a 230MHz wireless communication unit. The 230MHz wireless communication unit on the concentrator 208 side can use a directional tracking circularly polarized antenna. Circularly polarized waves have the characteristic of orthogonal polarization rotation, that is, when a circularly polarized wave encounters an obstacle and is reflected during transmission, the polarization rotation direction of its reflected wave is reversed (if the incident wave is right-handed circularly polarized, the reflected wave is left-handed circularly polarized. Conversely, if the incident wave is left-handed circularly polarized, the reflected wave is right-handed circularly polarized). Therefore, when the polarization rotation direction of the electromagnetic wave reflected by buildings, forests, hills, water surfaces, etc. is reversed, the above-mentioned reflected wave will not cancel the field strength of the incident wave at the receiving end, and the reflected wave will not be received by the circularly polarized antenna at the receiving end.

[0089] Compared with the current conventional linearly polarized antennas, using circularly polarized antennas can avoid clutter and multipath interference, and improve the anti-interference ability and the reliability of meter reading data transmission. The directional tracking circularly polarized antenna mainly consists of a directional circularly polarized microstrip antenna and a servo turntable. The directional microstrip antenna has the advantages of strong radiation directivity and high gain, which can improve the communication quality and reliability. The servo turntable can rotate within a horizontal range of 360°, and drive the directional microstrip antenna to rotate synchronously to align with the collector 202, collector 204 for uploading meter reading data, or the corresponding smart meters 201, 203, as well as other collectors or their corresponding smart meters.

[0090] The concentrator 208 can monitor the dual-mode meter reading channels. Whichever channel can establish a normal connection with the concentrator 208, the concentrator 208 will read, store, and process the meter reading data uploaded by that channel. If both channels can establish a normal connection with the concentrator 208, then according to a certain rule protocol, only the data uploaded by one of the channels will be read, stored, and processed.

[0091] The 230MHz power wireless private network 209 is used for data interaction between the system master station 210 and the concentrator 208.

[0092] The system master station 210 can complete the data interaction with the concentrator 208 through the 230 MHz power wireless private network 209. The system master station 210 can send commands such as power energy information query to the concentrator 208 through the 230 MHz power wireless private network 209, and receive, store, and process the meter reading data uploaded by the concentrator 208 through the 230 MHz power wireless private network 209. At the same time, the management personnel can access the data and manage the meter reading data transmission system through a personal computer (PC) terminal device. After the transmission of the meter reading data for one time is completed, the collectors 202, 204, the 230 MHz power wireless + high-speed power line carrier dual-mode modules 205, 206, 207, and the concentrator 208 enter the silent mode; at the same time, the communication channel of the 230 MHz power wireless private network 209 also enters the idle mode to receive the upload of the next meter reading data.

[0093] In this embodiment, the smart meters 201 and 203 communicate with the collectors 202 and 204 through data interfaces and communication protocols. The collectors 202 and 204 communicate with the 230 MHz power wireless + high-speed power line carrier dual-mode modules 205 and 206 through data interfaces and communication protocols respectively, and can transmit the meter reading data to the concentrator 208 through the dual-mode communication method (230 MHz power wireless private network communication and high-speed power line carrier communication). The 230 MHz power wireless + high-speed power line carrier dual-mode module 207 is on the concentrator 208 side, and the 230 MHz power wireless + high-speed power line carrier dual-mode modules 205 and 206 are on the smart meters 201 and 203 sides. The 230 MHz wireless communication units on the smart meters 201 and 203 sides adopt omnidirectional circularly polarized antennas, while the 230 MHz wireless communication unit on the concentrator 208 side adopts a directional tracking circularly polarized antenna. Compared with the existing linearly polarized antenna, the use of the circularly polarized antenna avoids clutter and multipath interference, improves the anti-interference ability, and improves the reliability and efficiency of the meter reading data transmission.

[0094] Figure 3 is a schematic diagram of the system structure diagram of a directional tracking circularly polarized antenna according to an embodiment of the present invention, as Figure 3 shown, the directional tracking circularly polarized antenna system includes: a directional circularly polarized microstrip antenna 302 and a servo turntable 304.

[0095] The directional circularly polarized microstrip antenna 302. The directional antenna has the advantages of high gain and strong directivity, which can improve the quality of the received signal and enhance the reliability and stability when the meter reading data is transmitted from the collector end to the concentrator through the 230 MHz power wireless private network. The directional circularly polarized microstrip antenna 302 can be mounted on a tablet, and the tablet can be fixed on the servo turntable 304.

[0096] The servo turntable 304. A GPS positioning device and an electronic compass can be installed on the servo turntable 304. According to the longitude and latitude information of the smart meter provided by the GPS positioning device on the smart meter side, the servo turntable 304 can activate the GPS data acquisition function, and then the servo turntable 304 can drive the tablet to rotate synchronously. When the radiation pattern of the directional circularly polarized microstrip antenna 302 points to the collector for uploading the meter reading data or its corresponding smart meter, the pose of the servo turntable 304 is automatically locked. When it is necessary to collect the electrical energy information of the next smart meter, the servo turntable 304 drives the tablet to rotate so that the radiation pattern of the directional circularly polarized microstrip antenna 302 points to the collector for uploading the meter reading data at that moment or its corresponding smart meter. Thus, the electrical energy information of multiple smart meters (such as charging piles) distributed in different areas is collected, improving the collection efficiency.

[0097] In this embodiment, by driving the directional circularly polarized microstrip antenna 302 through the servo turntable 304, the problems of signal blockage, multipath effect and interference in a complex environment can be effectively overcome, improving the stability and efficiency of data transmission, which is of great significance for the real-time transmission of meter reading data, load forecasting and resource scheduling of virtual power plants.

[0098] In the embodiment of the present invention, the meter reading data is transmitted to the concentrator in a dual-mode communication manner (230 MHz power wireless private network communication and high-speed power line carrier communication), and data interaction between the concentrator and the system master station is carried out through the 230 MHz power wireless private network. The 230 MHz wireless communication unit on the smart meter side uses an omnidirectional circularly polarized antenna, and the 230 MHz wireless communication unit on the concentrator side uses a directional tracking circularly polarized antenna. Through the servo turntable and radiation pattern adjustment, the directional circularly polarized antenna can be accurately aligned with a specific smart meter or collector, ensuring the reliability and efficiency of signal transmission. Thus, an efficient, stable, anti-interference and secure data transmission scheme is provided, solving the technical problem of low data transmission efficiency and achieving the technical effect of improving data transmission efficiency.

[0112] Embodiment 4

[0113] Figure 5 is a schematic structural diagram of a device data transmission system according to an embodiment of the present invention, as Figure 5 shown. The device data transmission system 500 includes: a collector 502, a concentrator 504, and a master station 506.

[0114] The collector 502 is used to obtain the device data of the target power device; based on the device data, detect the communication policy set of the target power device to obtain the target communication policy, where the communication policy set includes at least one communication policy, and the target communication policy is used to represent the communication policy with the maximum performance index in the communication policy set, and the performance index is used to represent the transmission performance of the collector transmitting the device data to the concentrator; transmit the device data to the concentrator according to the target communication policy.

[0115] The concentrator 504 is used to transmit the device data received from the collector to the master station.

[0116] The master station 506 is used to store and process the device data received from the concentrator.

[0117] In this embodiment, the collector can be installed on each power device (such as a smart meter) to collect the device data of the target power device during operation. For example, the operating status, performance parameters, power readings, etc. of the target power device are used to monitor and analyze the working conditions of the target power device in real time. After obtaining the device data of the target power device, perform a performance test on the communication policy set of the target power device to evaluate the transmission performance of different communication policies, such as signal strength, data transmission rate, bit error rate, and delay time, etc. The communication policy set may include, but is not limited to, the 230MHz power wireless private network communication policy and the high-speed power line carrier communication policy. Through detection, the collector can determine the communication policy with the maximum performance index as the target communication policy, and transmit the device data to the concentrator according to the target communication policy.

[0118] In this embodiment, the concentrator is a data aggregation and relay node in the system, responsible for receiving the device data from multiple collectors, and performing preliminary processing on it, such as data format conversion, checksum, and summarization, and then transmitting the device data to the master station through a higher-level network (such as optical fiber, 230MHz power wireless private network) to complete the relay task of the device data.

[0119] In this embodiment, the master station is a data processing and control center in the entire device data transmission system, which can receive the device data uploaded by the concentrator and perform data storage, analysis, and decision-making. The master station can store based on the collected device data and perform advanced functions such as power load forecasting, demand response scheduling, and power market trading.

[0120] As an alternative embodiment, the concentrator includes a dual-mode module. The dual-mode module includes a first communication component and a second communication component. The communication policy set includes a first communication policy and a second communication policy. The first communication component corresponds to the first communication policy, and the second communication component corresponds to the second communication policy. If the connection status between the first communication component and the concentrator is normal, and the connection status between the second communication component and the concentrator is abnormal, the target communication policy is the first communication policy; if the connection status between the second communication component and the concentrator is normal, and the connection status between the first communication component and the concentrator is abnormal, the target communication policy is the second communication policy.

[0121] In this embodiment, the concentrator side may include a dual-mode module. For example, a 230MHz power wireless + high-speed power line carrier dual-mode module. Then the first communication component may be a 230MHz power wireless communication component, and the second communication component may be a high-speed power line carrier communication component. The first communication component corresponds to the first communication policy (230MHz power wireless communication policy), and the second communication component corresponds to the second communication policy (high-speed power line carrier communication policy). If the connection status between the first communication component and the concentrator is normal, and the connection status between the second communication component and the concentrator is abnormal, the target communication policy may be the first communication policy; if the connection status between the second communication component and the concentrator is normal, and the connection status between the first communication component and the concentrator is abnormal, the target communication policy may be the second communication policy.

[0122] Optionally, when the communication policy set includes a first communication policy (such as, 230MHz power wireless private network communication policy) and a second communication policy (such as, high-speed power line carrier communication policy), the concentrator can monitor the dual-mode meter reading channels. Whichever channel can establish a normal connection with the concentrator, the concentrator will read, store, and process the meter reading data uploaded by this channel.

[0123] As an alternative embodiment, the concentrator includes a dual-mode module. The dual-mode module includes a first communication component and a second communication component. The communication policy set includes a first communication policy and a second communication policy. The first communication component corresponds to the first communication policy, and the second communication component corresponds to the second communication policy. If the connection status between the first communication component and the concentrator is normal, and the connection status between the second communication component and the concentrator is normal, the target communication policy is the third communication policy, where the third communication policy is the communication policy with the largest performance index among the first communication policy and the second communication policy.

[0124] In this embodiment, if the connection status between the second communication component and the concentrator and the connection status between the first communication component and the concentrator are both in a normal state, that is, the channels where the two communication components are located can both establish normal connections with the concentrator, data uploaded through only one of the channels can be read, stored, and processed according to certain rule protocols. Then the target communication policy can be the third communication policy, where the third communication policy can be the communication policy with the maximum performance index for transmitting device data among the first communication policy and the second communication policy.

[0125] Optionally, the collector continuously monitors the connection status between its first communication component and second communication component and the concentrator, and judges whether the connection is stable through indicators such as signal strength, bit error rate, and delay time. Once the connection statuses of both components are detected as normal states simultaneously, that is, the signal quality is good, the bit error rate is low, and the delay time is within an acceptable range, the communication policy selection stage can be entered. The communication policy with the maximum performance index will be regarded as the selection that meets the requirements in the current environment, that is, this communication policy can transmit data with the highest efficiency, the lowest energy consumption and cost, and the highest security.

[0126] As an alternative embodiment, the concentrator includes a directional tracking circularly polarized antenna, and the directional tracking circularly polarized antenna includes a directional circularly polarized antenna and a servo turntable. If there is a next power device of the target power device among the concentrated power devices, the servo turntable is used to adjust the pointing direction of the radiation pattern of the directional circularly polarized antenna to the direction where the next power device is located, and the directional circularly polarized antenna is used to transmit a prompt message to the next power device, where the prompt message is used to prompt the next power device to transmit device data to the transmission system.

[0127] In this embodiment, the dual-mode module (230MHz wireless and power line carrier dual-mode module) on the concentrator side is configured with a directional tracking circularly polarized antenna, which consists of a directional circularly polarized antenna and a servo turntable. If there is a next power device of the target power device among the concentrated power devices, the servo turntable can be used to adjust the pointing direction of the radiation pattern of the directional circularly polarized antenna to the direction where the next power device is located. For example, the pointing direction of the radiation pattern of the directional circularly polarized antenna is adjusted according to the position information (such as GPS longitude and latitude) of the next power device to ensure that the directional circularly polarized antenna is accurately aligned with the next power device. The directional circularly polarized antenna can be used to transmit a prompt message to the next power device. Wherein, the prompt message is used to prompt the next power device to transmit device data to the transmission system.

[0128] Optionally, the 230 MHz wireless communication component on the smart meter side can adopt an omnidirectional circularly polarized antenna, which can receive signals from all directions, reduce the influence of multipath effects and signal blockage, and improve the stability and reliability of the received signals. The 230 MHz wireless communication component on the concentrator side can adopt a directional tracking circularly polarized antenna. The directional circularly polarized antenna has the characteristics of high gain, strong directivity, and narrow beam, which can improve the directivity and intensity of signal transmission, and reduce signal attenuation and interference. The servo turntable can accurately adjust the direction of the directional circularly polarized antenna pattern according to the instruction to ensure that the directional circularly polarized antenna accurately points to the target power equipment.

[0129] Optionally, the directional circularly polarized antenna can be mounted on a flat plate, and the flat plate can be fixed on the servo turntable. A GPS positioning device and an electronic compass can be installed on the servo turntable. According to the longitude and latitude information of the smart meter provided by the GPS positioning device on the smart meter side, the servo turntable enables the GPS number guiding function, and the servo turntable drives the flat plate to rotate synchronously. When the directional pattern of the directional circularly polarized antenna points to the collector for uploading meter reading data or its corresponding smart meter, the pose of the servo turntable is automatically locked. When it is necessary to collect the electrical energy information of the next smart meter, the servo turntable drives the flat plate to rotate so that the directional pattern of the directional circularly polarized antenna points to the collector for uploading meter reading data or its corresponding smart meter at that moment. Thus, the electrical energy information of multiple smart meters (such as charging piles) distributed in different regions can be collected, greatly improving the collection efficiency.

[0130] In the embodiment of the present invention, the collector obtains device data from the target power equipment and detects the communication policy set according to the real-time performance index. The concentrator is built-in with a dual-mode module, which supports the first communication policy (such as 230 MHz power wireless private network communication) and the second communication policy (such as high-speed power line carrier communication).
