Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of broadband power line carrier communication, and particularly relates to a listening method, device, equipment and system, a listening server and a storage medium. BACKGROUND

[0002] Power line communication (PLC) technology, also known as power line carrier communication technology, according to the definition in GB / T 31983.31, refers to a technology that modulates information data to a suitable carrier frequency and uses a power line as a physical medium to transmit data, so as to realize communication or control between data terminals. Since the power line is the most popular and widely covered physical medium, using the power line to transmit data information has great convenience, and without re-wiring, all power-using devices connected to the power line can form a communication network to interact and communicate information. This method is simple to implement and convenient to maintain, and can effectively reduce operating costs and reduce the expenditure of building a new communication network, and thus has become the main communication means for smart grid, energy management, smart home, photovoltaic power generation, electric vehicle charging and the like.

[0003] Power line carrier communication can be divided into power line narrowband carrier communication and power line broadband carrier communication according to the working frequency band. The frequency range that can be used by the power line narrowband carrier communication is 3 kHz to 500 kHz. Since the bandwidth is relatively narrow, only a lower transmission rate communication service can be provided, and the anti-interference ability is weak. The power line broadband carrier communication, also known as high-speed power line carrier communication (HPLC), is a power line broadband carrier technology for data transmission on a low-voltage power line, and is mainly used in local communication of a low-voltage area power consumption information acquisition system (such as meter reading). It mainly adopts orthogonal frequency division multiplexing (OFDM) technology, and uses a frequency band of 700 KHz-12 MHz. Among them, the working frequency range of the broadband power line carrier communication for power meter reading contains four frequency bands of Band0-Band3, which are 1.953 MHz-11.9 MHz, 2.441 MHz-5.615 MHz, 0.781 MHz-2.930 MHz and 1.758 MHz-2.930 MHz, respectively. The broadband has a relatively wide bandwidth, and can provide a data transmission rate of several hundred kbps to several Mbps. The noise of the power line in the high frequency band is relatively weak, and the communication reliability and stability are significantly improved compared with the narrowband power line communication. Compared with the traditional low-speed narrowband power line carrier technology, the HPLC technology has a large bandwidth and a high transmission rate, and can meet the higher requirements of low-voltage power line carrier communication.

[0004] In the power network system, the quantification of power grid loss has been a difficult problem. The power grid loss (referred to as line loss) refers to the power loss and loss generated in the process of power transmission, power transformation, power distribution and marketing in each link of the power transmission from the power plant to the customer. However, the current situation is that the distribution network department responsible for power transmission and power transformation and the marketing department responsible for the end user belong to different systems, and the data of each other is not disclosed, and the distribution network department does not measure the energy consumption data, so it cannot know the power consumption of a specific line, and currently only relies on the measurement data of the marketing department to calculate the line loss, so there is an urgent need for a means that can calculate the energy consumption data by section and can return in real time to evaluate the line loss by using the returned energy consumption data.

[0005] In addition, the current HPLC module only has communication function or only has listening function, and cannot realize listening and data transmission at the same time, and is limited by the carrier sense multiple access / collision detection (referred to as CSMA / CD) design characteristics of the HPLC system. If the listening data return and the existing power meter reading are in the same frequency band, interference will inevitably occur.

[0006] Based on the above demand for calculating energy consumption data by section and the conflict point, there is an urgent need to propose a listening data return method in the HPLC system without interference, which can realize listening and data transmission at the same time, can calculate energy consumption data by section and can return in real time, and solve the problem of incorrect quantification of line loss caused by the mutual non-disclosure of data between different system departments.

[0066] The present application is described in the following based on embodiments, but the present application is not limited to these embodiments only. In the following detailed description of the present application, some specific details are described in detail. The present application can also be completely understood without the description of these details by those skilled in the art. In order to avoid confusion of the essence of the present application, the well-known methods, processes, flows, elements and circuits are not described in detail.

[0067] In addition, those skilled in the art should understand that the drawings provided herein are for illustrative purposes only, and the drawings are not necessarily drawn to scale.

[0068] At the same time, it should be understood that in the following description, "circuit" refers to a conductive loop composed of at least one element or sub-circuit through electrical or electromagnetic connection. When an element or circuit is said to be "connected to" another element or said to be "connected between" two nodes, it can be directly coupled or connected to another element or there can be intermediate elements, and the connection between elements can be physical, logical or a combination thereof. On the contrary, when an element is said to be "directly coupled to" or "directly connected to" another element, it means that there is no intermediate element between the two.

[0069] Unless the context clearly requires otherwise, throughout the description, the terms "comprise", "comprising", "included", "including" or the like are to be construed in an inclusive sense, as opposed to an exclusive or exhaustive sense; that is to say, in the sense of "including, but not limited to".

[0070] In the description of the present application, it should be understood that the terms "first", "second" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise stated.

[0071] Figure 1 is a flow chart of a listening method according to an embodiment of the present application, which is applied to a listening device, as shown in Figure 1 The listening method comprises the following steps:

[0072] Step S110: The first HPLC chip in the listening device listens to the data of the network to be listened to on a preset default frequency band.

[0073] The "listening device" described in this step is a device independent of the HPLC network node, which has the function of listening to the HPLC network data on a specific frequency band, and also has the function of sending the listened data to the listening server in the form of HPLC network carrier data for analyzing and processing these data. The listening device is coupled to the power line, and from the perspective of network topology, it is at the same level as the concentrator.

[0074] The "first HPLC chip" described in this step is a communication module supporting the power line broadband carrier communication protocol. Since it can collect HPLC data and send the collected HPLC data to the power line carrier communication network through its own module function, in the present application, the "first HPLC chip" only has the function of listening to the HPLC network data, and does not send any power line carrier data. This separates the "listening" and "communication" functions, which can effectively avoid interference.

[0075] The "preset default frequency band" described in this step can be set by writing into the NVM (Non-Volatile Memory) at the time of factory shipment, or by other means. It generally refers to the commonly used frequency band of the network to be listened to, such as Band2 used by the general marketing department. Therefore, when factory setting is performed, the default frequency band to be listened to can be set to Band2. In this way, after power-on, the listening device automatically listens to the data of the marketing department network on the Band2 frequency band.

[0076] Step S120: the first HPLC chip in the listening device sends the listened data of the listened network satisfying the preset data listening reporting mode to the second HPLC chip in the listening device, and the second HPLC chip sends the data to the power line broadband carrier communication network.

[0077] The second HPLC chip in the present step is also a communication module supporting the power line broadband carrier communication protocol, but different from the first HPLC chip, the second HPLC chip can receive data from the HPLC network and send HPLC data to the power line broadband carrier communication network, that is, the first HPLC chip only receiving HPLC network data must send the listened data to the power line broadband carrier communication network through the second HPLC chip, that is, the listening data and data backhaul are completed in two systems, and the first HPLC chip as the listening party does not send carrier data, so it does not interfere with the carrier communication network, thereby effectively avoiding mutual interference.

[0078] In the present application, in order to make the first HPLC chip listen and report specific types of data, the concept of "data listening reporting mode" is set, which is used to define the data type listened and reported by the first HPLC chip, that is, the first HPLC chip listens and reports the data of the listened network according to the set data listening reporting mode. When the listening device is powered on, the first HPLC chip can listen and report the data of the listened network according to the preset data listening reporting mode. During the listening period, the listening server or the upper computer can send a configuration data listening reporting mode instruction to change the data listening reporting mode, thereby controlling the data type listened and reported by the listening device. The data listening reporting mode includes but is not limited to: listening and reporting all data transmitted in both directions, listening and reporting only all data transmitted in the downlink, listening and reporting only all data transmitted in the uplink, listening and reporting application layer data transmitted in both directions, listening and reporting only application layer data transmitted in the downlink, listening and reporting only application layer data transmitted in the uplink, and prohibiting any data reporting. Of course, other data listening reporting modes can also be defined according to the actual needs of the project. When the data listening reporting mode is one of listening and reporting application layer data transmitted in both directions, listening and reporting only application layer data transmitted in the downlink, and listening and reporting only application layer data transmitted in the uplink, it means that the application layer data needs to be listened and reported, and then the listening device judges whether the data is application layer data through the identification in the data frame content after listening to the data of the listened network, so as to send only the application layer data of the listened network corresponding to the specific data listening reporting mode through the second HPLC chip, and discard other data which is not application layer data.

[0079] It should be noted that the first HPLC chip receives the data packets of the intercepted network, and needs to splice the content of each frame packet, then check whether it is complete and valid, and then transmit it to the second HPLC chip. The first HPLC chip and the second HPLC chip can be connected and data can be transmitted through a serial port or an SPI interface (i.e., the abbreviation of English "Serial Peripheral Interface"). In the future, there can be other connection methods, and the scheme of the embodiment of the application can be applied.

[0080] In addition, in order to facilitate project development, the first HPLC chip and the second HPLC chip can be two HPLC chips that are completely the same in hardware structure, and can also be different in actual application.

[0081] In addition to the above steps S110 and S120, the interception method of the embodiment of the application further includes that the first HPLC chip receives an interception configuration instruction sent by an interception server or a host computer, processes the interception configuration instruction, and if the interception configuration instruction needs to be replied, sends a reply instruction for the interception configuration instruction to the interception server or the host computer.

[0082] As can be known from the above-mentioned contents included by the interception method, the first HPLC chip responsible for "interception" can receive an interception configuration instruction sent by an interception server or a host computer, to configure parameters related to interception. The interception configuration instruction and the reply instruction for the interception configuration instruction can be sent in the following three ways.

[0083] Method 1: The host computer is directly connected with the serial port of the first HPLC chip, and the host computer directly sends the interception configuration instruction to the first HPLC chip through the serial port, and the first HPLC chip directly sends the reply instruction for the interception configuration instruction to the host computer through the serial port.

[0084] Method 2: The host computer is connected with the serial port of the second HPLC chip, and the second HPLC chip receives the interception configuration instruction and forwards it to the first HPLC chip through another serial port or an SPI interface, and the first HPLC chip sends the reply instruction for the interception configuration instruction to the second HPLC chip through the serial port or the SPI interface, and the second HPLC chip forwards it to the host computer through the serial port.

[0085] Mode 3: The remote listening server sends a listening configuration instruction to the second HPLC chip through the HPLC network, the second HPLC chip forwards the listening configuration instruction to the first HPLC chip through the serial port or the SPI interface, the first HPLC chip sends a response instruction for the listening configuration instruction to the second HPLC chip through the serial port or the SPI interface, and the second HPLC chip sends the response instruction to the remote listening server through the HPLC network.

[0086] In the development of specific projects, one or more of the above three modes can be selected for sending a listening configuration instruction according to actual needs.

[0087] It should be noted that in the above three modes, the host computer is connected to the first HPLC chip or the second HPLC chip through a serial port, and in the future, other connection modes can also be applied to the above modes.

[0088] The specific format and content of the listening configuration instruction are realized by a manufacturer-defined extended frame. The following will mainly explain three listening configuration instructions:

[0089] The first kind is a configuration listening frequency offset synchronization target network object instruction. The frequency offset of the network being listened to will change with the change of the environment temperature, so in order to obtain a higher listening reception success rate, the working frequency offset of the self needs to be synchronized to the network, and changes with the frequency offset of the network being listened to.

[0090] As shown in Figure 2 , the following steps are implemented:

[0091] Step S210: The first HPLC chip receives the configuration listening frequency offset synchronization target network object instruction sent by the listening server or the host computer.

[0092] The data unit format of the configuration listening frequency offset synchronization target network object instruction is shown in the following table:

[0093] Data Content Data Format Number of Bytes Synchronization Enable BIN 1 Target Network Object CCO Address HEX Big Endian 6

[0094] Among them, synchronization enable: 0 represents asynchronization; 1 represents synchronization enabled. The default is asynchronization.

[0095] Target network object CCO address: CCO address of the synchronization target network object.

[0096] Step S220: Send a response instruction confirmation for the configuration listening frequency offset synchronization target network object instruction to the listening server or the host computer.

[0097] The response instruction includes confirmation and denial, and in general, the response instruction confirmation is sent.

[0098] Step S230: Synchronize the self-listening frequency offset to the target network object.

[0099] The first HPLC chip determines the target network object according to the "target network object CCO address" field in the above-mentioned data unit format, and then performs the operation of synchronizing to the target network object in this step S230. The specific operation method is as follows:

[0100] Receive any two network beacon data of the target network object, which are respectively denoted as the first network beacon data and the second network beacon data. Obtain the sending time stamps in the received first network beacon data and the second network beacon data respectively, and calculate the difference between the sending time stamp of the first network beacon data and the sending time stamp of the second network beacon data, denoted as ΔT tx Then, obtain the receiving time stamps of the first network beacon data and the second network beacon data received by the self respectively, and calculate the difference between the receiving time stamp of the first network beacon data received by the self and the receiving time stamp of the second network beacon data received by the self, denoted as ΔT rx Then, determine the frequency offset value according to ΔT tx and ΔT rx Finally, use the determined frequency offset value to calibrate the working frequency of the self-crystal oscillator.

[0101] Wherein, when determining the frequency offset value according to ΔT tx and ΔT rx , the following formula can be used for calculation:

[0102]

[0103] Wherein, ΔF is the frequency offset value, ΔT rx is the difference between the receiving time stamp of the first network beacon data received by the self and the receiving time stamp of the second network beacon data received by the self, and ΔT tx is the difference between the sending time stamp of the first network beacon data and the sending time stamp of the second network beacon data.

[0104] After synchronizing the target network object, the receiving success rate of the listening device to other networks may decrease, while the receiving success rate to the target network object increases.

[0105] It should be noted that the operation of synchronizing the listening frequency offset to the target network object is a continuous process, that is, the operation of continuously calculating the frequency offset value and calibrating the working frequency of the self-crystal oscillator is required, so as to keep the frequency offset synchronized with the target network object at all times, thereby improving the success rate of receiving and listening data.

[0106] The second kind: configure the listening frequency band instruction. When the listening device is powered on, the first HPLC chip responsible for listening works in the common frequency band of the network being listened to by default. When the working frequency band of the network being listened to changes, the listening frequency band of the first HPLC chip needs to be modified. As shown in the following table, the specific implementation is as follows: Figure 3

[0107] Step S310: The first HPLC chip receives the configuration listening frequency band instruction sent by the listening server or the upper computer, and obtains the target frequency band to be switched to included in the configuration listening frequency band instruction.

[0108] The data unit format of the configuration listening frequency band instruction is shown in the following table:

[0109] Data Content Data Format Number of Bytes Target Frequency Band BIN 1

[0110] Wherein, the target frequency band: 0 represents Band0, 1 represents Band1, 2 represents Band2, 3 represents Band3, and 4 represents all frequency bands.

[0111] Step S320: Switch the listening frequency band of itself from the default frequency band to the target frequency band.

[0112] Step S330: If the current frequency offset value is not the pre-set default frequency offset value, set the current frequency offset value to the default frequency offset value.

[0113] In this step, since the listening frequency band has changed, the frequency offset value needs to be reset to the default frequency offset value. The default frequency offset value can be set by writing into the NVM at the time of factory shipment, or can be set or obtained by other means. When the frequency offset of the network being listened to changes, the current frequency offset value is updated and synchronized again by using steps S210-S230.

[0114] Step S340: Listen to the network being listened to on the target frequency band.

[0115] Step S350: Send a response instruction confirmation to the configuration listening frequency band instruction to the listening server or the upper computer.

[0116] The response instruction includes confirmation and denial. In general, the response instruction confirmation is sent.

[0117] By configuring the listening frequency band instruction, the listening frequency band of the first HPLC chip responsible for the listening function can be configured to be completely different from the working frequency band of the second HPLC chip responsible for the data backhaul function, so that the carrier network paths of listening and data backhaul are completely separated, further reducing the interference during data backhaul.

[0118] ​The third is a configuration data listening reporting mode instruction. The instruction is used for indicating whether the listening device performs listening and a data mode to be reported by listening. When the listening server or the upper computer needs to change the data mode reported by the listening device during listening to the data of the network to be listened to, the listening server or the upper computer sends a configuration data listening reporting mode instruction to the listening device, as shown in the following table, and the listening device changes the data listening reporting mode according to the configuration data listening reporting mode instruction. Figure 4 The configuration data listening reporting mode instruction is implemented by the following steps.

[0119] In step S410, the first HPLC chip receives the configuration data listening reporting mode instruction sent by the listening server or the upper computer, and obtains the data listening reporting mode contained in the configuration data listening reporting mode instruction.

[0120] The specific data unit format of the configuration data listening reporting mode instruction is shown in the following table.

[0121] Data Content Data Format Number of Bytes Data Listening Reporting Mode BIN 1

[0122] The data listening reporting mode is as follows: 0 represents listening to all messages transmitted in both directions; 1 represents listening to all messages transmitted in the downlink direction only; 2 represents listening to all messages transmitted in the uplink direction only; 3 represents listening to application layer messages transmitted in both directions; 4 represents listening to application layer messages transmitted in the downlink direction only; 5 represents listening to application layer messages transmitted in the uplink direction only; and 6 represents prohibiting reporting of any message.

[0123] In step S420, the current data listening reporting mode is changed to the data listening reporting mode contained in the configuration data listening reporting mode instruction, and the network data to be listened to is reported according to the data listening reporting mode contained in the configuration data listening reporting mode instruction.

[0124] The current data listening reporting mode refers to the “preset data listening reporting mode” at power-on or the data listening reporting mode changed by the configuration data listening reporting mode instruction before.

[0125] In step S430, a response instruction confirmation to the configuration data listening reporting mode instruction is sent to the listening server or the upper computer.

[0126] The response instruction contains confirmation and denial, and the response instruction confirmation is generally sent.

[0127] Another embodiment of the application further provides a listening method applied to a listening server, and at least comprising: receiving data of a network to be listened to, which is listened to by a first HPLC chip in a listening device and reported by a second HPLC chip in the listening device, and satisfying a preset data listening reporting mode.

[0128] In addition, the listening method further comprises: sending a listening configuration instruction to the listening device, and receiving a response instruction of the listening device to the listening configuration instruction if the listening configuration instruction needs a response.

[0129] Specifically, the sending of the listening configuration instruction to the listening device and the receiving of the response instruction of the listening device to the listening configuration instruction specifically include three aspects:

[0130] The first aspect: sending a configuration listening frequency band instruction to the listening device, wherein the configuration listening frequency band instruction contains a target frequency band to be switched to; and receiving a response instruction of the listening device to the configuration listening frequency band instruction.

[0131] The second aspect: sending a configuration listening frequency offset synchronization target network object instruction to the listening device; and receiving a response instruction of the listening device to the configuration listening frequency offset synchronization target network object instruction.

[0132] The third aspect: sending a configuration data listening reporting mode instruction to the listening device, wherein the configuration data listening reporting mode instruction contains a data listening reporting mode to be configured; and receiving a response instruction of the listening device to the configuration data listening reporting mode instruction.

[0133] The data listening reporting mode includes but is not limited to: listening to and reporting all data in bidirectional transmission, listening to and reporting all data in downlink transmission only, listening to and reporting all data in uplink transmission only, listening to and reporting application layer data in bidirectional transmission only, listening to and reporting application layer data in downlink transmission only, listening to and reporting application layer data in uplink transmission only, and prohibiting any data reporting.

[0134] In addition to the above, the listening method further comprises:

[0135] After the listening server receives the data of the listened network reported by the listening device, the data is analyzed and processed, for example, the data can be used for line loss evaluation, line load statistics or segment-by-segment energy consumption data statistics. In line loss evaluation, line load statistics or energy consumption data statistics, the application layer data of the listened network needs to be obtained. The listening server can instruct the listening device to report the application layer data of the listened network by issuing a configuration data listening reporting mode instruction, such as "listening and reporting bidirectional transmission of application layer data", "only listening and reporting downlink transmission of application layer data" or "only listening and reporting uplink transmission of application layer data". In this way, the application layer data of the listened network can be directly received from the listening device to evaluate the line loss. If the listening server receives all the data of the listened network, the listening server needs to obtain the application layer data of the listened network from all the received data of the listened network, and then use the obtained application layer data of the listened network for statistical operation, which includes but is not limited to line loss evaluation, line load statistics and energy consumption data statistics.

In addition, the listening server receives the application layer data of the listened network listened by the listening device, realizes the function of segment-by-segment energy consumption data statistics, further uses the application layer data to evaluate the line loss, and solves the problem of incorrect quantification of line loss caused by the fact that data of different departments is not open to each other.

[0137] The embodiment of the application further provides a listening device arranged in a listening server, which at least comprises: a listening data receiving module arranged to receive data of a listened network listened by a first HPLC chip in a listening device and reported by a second HPLC chip in the listening device, the data satisfying a preset data listening reporting mode.
