Description

Technical Field

[0001] The present application relates to the technical field of self-organizing networks, and in particular to a multi-level networking system and method for power self-organizing network communications. Background Art

[0002] The power system is an extremely complex system. Among low-voltage power users, there are a large number of power users under a public distribution transformer with low power consumption capacity, but the low-voltage side terminal points are numerous and relatively scattered. The distance between nodes is generally no more than 500 meters. The requirements for local communication focus on the balance between economy and availability, and can ensure the reliability and real-time nature of communication. Power ad hoc network communication technology is an advanced communication solution that allows power equipment nodes to automatically establish, manage and maintain communication links by utilizing wireless or wired communication links, thereby ensuring that nodes can communicate with each other and form a flexible and reliable communication network.

[0003] At present, the commonly used local communication technologies mainly include HPLC (High-speed Power Line Communication), micro-power wireless HRF, RF-mesh, HPLC+HRF dual-mode and HPLC+RF-mesh dual-mode technologies, etc. These communication transmission technologies constitute a communication bridge between different power equipment and are often used in the fields of power consumption information collection, power equipment status monitoring, smart home, etc.

[0004] At present, after the development of ad hoc network communication technology, the common laboratory test environment is to build a 220V strong power environment, install local communication nodes on terminal devices such as electric meters or LTUs (Line Terminating Units), and form a stable communication network through ad hoc network technology. However, this strong power environment is not very safe on the one hand, and on the other hand, it is difficult to build a multi-level network because there is no isolation or interference between strong currents and the laboratory space is limited. Most of them can only form a level 1, and a few level 2 to 3 network environments, which cannot simulate and match the actual use scenarios on site well, resulting in the inability to cover multi-level network conditions and insufficient testing. On the other hand, the cost of terminals such as electric meters or LTUs is relatively high. When constructing a large-scale node network, the cost is high and the site occupies a large area. Summary of the invention

[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] The present application embodiment provides a multi-level networking system for power self-organizing network communication, such as Figure 1 As shown, the system includes: a main control system, several analog terminal systems and several adjustable attenuators; the main control system includes an analog edge device unit for deploying a master node and several first analog terminal units for deploying slave nodes, each analog terminal system includes several second analog terminal units for deploying slave nodes, and the main control system and the analog terminal system, as well as each analog terminal system, are connected via adjustable attenuators.

[0043] Among them, the adjustable attenuator can support 0-120dB attenuation adjustment and is used to adjust the power level between two boards. It has the characteristics of small size, high precision, stability and reliability.

[0044] The analog edge device unit is an MCU powered by three phases. It can be connected to the edge device main node and can be connected to the computer via RS232 and operated through the analog concentrator host computer.

[0045] The main control system and one of the analog terminal systems are connected via an adjustable attenuator, and each analog terminal system is connected in turn via an adjustable attenuator.

[0046] The first simulation terminal unit and the second simulation terminal unit are both composed of an MCU, powered by three phases, can be connected to single-phase and three-phase communication slave nodes, and can simulate the behavior of terminal devices such as electric energy meters and LTUs, and can respond and reply when the communication nodes read metering data.

[0047] In other embodiments, the main control system further includes a log aggregation unit, a WiFi transmission unit, a first RF signal aggregation unit, a network port transmission unit, a monitoring unit, and a USB transmission unit. The simulation terminal system further includes a log aggregation unit, a WiFi transmission unit, and a second RF signal aggregation unit, and the functions of these units are basically the same as those of the units corresponding to the names of the main control system.

[0048] The log aggregation unit aggregates the serial port logs of all slave nodes on the master control system or the simulated terminal system, and the log of each slave node is distinguished by a special identifier.

[0049] The WiFi transmission unit is capable of transmitting and aggregating the logs of the log aggregation unit, as well as command messages, command echoes, power control messages and other data through the WiFi protocol.

[0050] The first RF signal aggregation unit and the second RF signal aggregation unit aggregate the wireless signals (RF signals) of all slave nodes on the main control system or the analog terminal system and transmit them to the wireless space uniformly. They can also receive them uniformly and transmit them to the connected slave nodes respectively. At the same time, the signal attenuation can be controlled through an adjustable attenuator.

[0051] The network port transmission unit is used to transmit the self-organizing network communication technology message obtained by the monitoring unit to the computer through the network port transmission unit, and the message is displayed on the computer host computer.

[0052] The USB transmission unit is a serial-to-USB transmission unit, which is used to transmit the messages received by the WiFi transmission unit to the computer via the USB transmission unit.

[0053] The monitoring unit is composed of a concentrator type I communication unit of the ad hoc networking technology, and is mainly capable of monitoring the data transmission and reception of ad hoc networking communication technology on the power line or in the wireless space.

[0054] In one embodiment, the first analog terminal unit and the second analog terminal unit can be connected to the communication node through a standard weak current interface and a carrier coupling interface, and interactively communicate through a UART (Universal Asynchronous Receiver-Transmitter) serial port, supporting DL / T645 and DL / T698.45 dual protocols.

[0055] In one embodiment, the multi-level networking system includes a primary level and several secondary levels; the first analog terminal unit of the main control system is configured at the primary level, and each analog terminal system is configured at the primary level and the secondary levels respectively.

[0056] like Figure 2 As shown, the first level (i.e., the primary level) includes slave nodes on the master control system and slave nodes on several simulated terminal systems, and other simulated terminal systems are sequentially configured at other sub-levels. For example, in a 5-level multi-layer network environment, when there are 22 simulated terminal systems, the first two simulated terminal systems can be configured at the first level, and the other 20 simulated terminal systems can be configured in groups of 5 at the second, third, fourth, and fifth levels in sequence.

[0057] In one embodiment, the adjustable attenuator includes a wired adjustable attenuator and a wireless adjustable attenuator; by adjusting the attenuation of the wired adjustable attenuator and the wireless adjustable attenuator, the multi-level networking system is constructed into a wired network, a wireless network, and a wireless and wired hybrid network.

[0058] The main control system and the analog terminal system are connected via a wired adjustable attenuator, and each analog terminal system is configured with a wired adjustable attenuator and a wireless adjustable attenuator. In this embodiment, the wired adjustable attenuator and the wireless adjustable attenuator between each analog terminal system are adjusted.

[0059] If the environment is purely wired, adjust the wired adjustable attenuator to NdB and the wireless adjustable attenuator to MdB. If the environment is purely wireless, adjust the wired adjustable attenuator to MdB and the wireless adjustable attenuator to NdB. If the environment is a mixture of wired and wireless, adjust the wired adjustable attenuator between some analog terminal systems to NdB and the wireless adjustable attenuator to MdB; and adjust the wireless adjustable attenuator between another part of the analog terminal systems to NdB and the wired adjustable attenuator to MdB. Among them, the N value is in the range of [40,70]dB, and the M value is in the range of [70,110]dB. The N value and M value here are a feasible implementation plan for an adjustable attenuator with an adjustable range of [0,120]dB, which can be set according to the performance, working conditions, adjustable range, etc. of the adjustable attenuator.

[0060] In an implementation regulation, a method for using an embodiment of a multi-level networking system for power self-organizing network communication based on the above-mentioned method is provided, and the method includes: sending a command message to the main control system, and the main control system transmits the command message to the simulation terminal system specified by the command message; using the simulation terminal system to receive and parse the command in the command message, and transmit the command to the slave node specified by the command, so that the slave node responds to the command; using the simulation terminal system to collect the response log of the slave node to the command, and feed the log back to the main control system; the main control system uploads the log.

[0061] like Figure 3 As shown, this embodiment proposes to implement the functions of command echo and log aggregation display on a multi-level self-organizing network system, which can view the status of network nodes in real time and can be used as an important means of positioning test, enriching the availability and observability of the environment. The implementation of this function includes the following steps:

[0062] Step 1: The host computer specifies a slave node to input a command.

[0063] The slave node supports many local commands and can view its own version, status, communication interaction and other information. The command message frame format for interaction between the host computer and the slave node is defined as follows:

[0064]

[0065]

[0066] The format of the command input on the upper computer interface is "function type + identifier + command", and the lower layer of the upper computer will convert the command into a command message in the above format and forward it to the main control system, and the function type is 1. For example, in this embodiment, "115version" means sending the command version to slave node 15 to check the slave node version number.

[0067] Step 2: The command message is transmitted to the WiFi transmission unit of the main control system through the USB transmission unit of the main control system.

[0068] Step 3: The WiFi transmission unit of the main control system transmits the command message to the WiFi transmission unit of the simulation terminal system.

[0069] Step 4: The WiFi transmission unit transmits the command message to the second simulation terminal unit.

[0070] The second simulation terminal unit acts as an intermediate bridge between the WiFi transmission unit and the log aggregation unit. It will periodically query the identification number of the slave node until all the slave nodes on the simulation terminal system are obtained. It maintains a table of slave node identification numbers and corresponding serial ports. When the second simulation terminal unit obtains the command message and parses it, it will process it only when it finds that it is a slave node on its own simulation terminal system.

[0071] Step 5: After parsing the command, the second simulation terminal unit transmits the command to the designated slave node device, and the slave node responds to the command.

[0072] When the second simulated terminal unit determines that the slave node command is a slave node on the terminal system, it parses the command message into a command and transmits it to the designated slave node through the log aggregation unit. The slave node responds to the command after receiving it.

[0073] Step 6: Access the log aggregation unit from the node serial port.

[0074] Step 7: The log aggregation unit transmits the log to the WiFi transmission unit of the main control system through the WiFi transmission unit.

[0075] The command echo or slave node log obtained by the log aggregation unit is processed by the second simulation terminal unit and converted into a message and transmitted to its own WiFi transmission unit, and the WiFi transmission unit transmits the message to the WiFi transmission unit on the main control system.

[0076] Step 8: After receiving the message, the WiFi transmission unit of the main control system transmits the message to the computer via the USB transmission unit.

[0077] The WiFi on the main control system is the WiFi master device and is the only WiFi device that can interact with the computer. After receiving the message, the WiFi transmission unit transmits the message to the computer through the USB transmission unit.

[0078] Step 9: The host computer displays logs and command echo information in real time.

[0079] If the upper computer receives a command message, it will output the command message and display it in the command echo box. If it is a log message, it will display the log in the log display box.

[0080] Among them, steps 6 and 9 are the main steps of the slave node log aggregation and echo function.

[0081] In other embodiments, the designated slave node can be distinguished according to the terminal identification number of the slave node after joining the network, because the slave node terminal identification of each network is unique.

[0082] In other embodiments, if the designated slave node is on the master control system, the WiFi transmission unit of the master control system does not need to transmit the command message to the WiFi transmission unit of the simulation terminal system.

[0083] In other embodiments, in step 6, the serial port of the slave node is connected to the log aggregation unit by connecting four UART wires of the slave node to the UART of the log aggregation unit.

[0084] In one embodiment, the method of use also includes: sending a control message to the main control system, and the main control system transmits the control message to the simulation terminal system specified by the control message, so that the simulation terminal system completes the power on and off operation in response to the control message.

[0085] This embodiment proposes a method for remotely controlling the power on and off of a slave node, which can improve the feasibility and flexibility of the active reporting test of power outage and restoration. Active reporting of power outage and restoration changes from passive emergency repair to active emergency repair, improves power supply reliability, and enhances customer service guarantee capabilities. The implementation of this function includes the following steps:

[0086] Step 1: The host computer specifies the power on and off of the slave node device. The slave node can be distinguished according to the terminal identification number of the slave node after entering the network, because the slave node identification number of each network is unique.

[0087] The command message frame format for the host computer to control the power-on and power-off interaction of the slave point is defined as follows:

[0088]

[0089]

[0090] The format of inputting control power on and off on the upper computer interface is "function type + slave node identification number", for example "410", which means powering off the device of slave node 10. The lower layer of the upper computer will convert this command into the above-mentioned control power message and forward it to the main control system, with function type 3.

[0091] Step 2: The control message is transmitted to the WiFi transmission unit of the main control system through the USB transmission unit of the main control system.

[0092] Step 3: The WiFi transmission unit of the main control system transmits the command message to the WiFi transmission unit of the designated simulation terminal system.

[0093] Step 4: The WiFi transmission unit transmits the message to the second simulation terminal unit where the designated slave node is located.

[0094] The second analog terminal unit is composed of an MCU, which periodically queries the identification number of the slave node and maintains the relationship between the slave node and the corresponding control pin.

[0095] Step 5: The second analog terminal unit performs a power-on or power-off operation in response to the power-on or power-off instruction.

[0096] The MCU of the second analog terminal unit parses the power control message to designate a slave node to perform power-on or power-off operation.

[0097] In one embodiment, the method of use also includes: connecting the main control system to the power line; the monitoring unit on the main control system has a dual-mode communication function of wired and wireless, and can monitor the data transmission and reception on the wired and wireless space of the power line, obtain monitoring data and upload it.

[0098] This embodiment proposes a message that can monitor wired and wireless networks such as power lines and wireless spaces, and can be displayed on the host computer. Obtaining this message is more conducive to on-site operation and maintenance to locate problems, and can clearly understand the interaction process of the message and deeply understand the operation mechanism of the self-organizing network technology. The following steps are included to realize this function:

[0099] Step 1: Connect the main control system to the neutral and live wires of the power line.

[0100] The main control system includes a monitoring unit, which can monitor the interactive messages between the multi-level self-organizing network. The main control system can also be connected to the existing network environment, and only the live wire L and the neutral wire N are connected to monitor the interactive messages of the existing network environment. In this embodiment, the monitoring message is used in the multi-level self-organizing network environment.

[0101] Step 2: The monitoring unit transmits the monitoring message to the computer via the network port transmission unit.

[0102] The monitoring unit has wired and wireless dual-mode communication functions, can monitor interactive messages on power lines and wireless spaces, and transmit the monitored messages to the computer through the network port transmission unit.

[0103] Step 3: The host computer displays the monitoring message in real time.

[0104] The host computer obtains the messages transmitted by the network port, can display the monitoring messages in real time, and can distinguish whether the monitoring messages are link layer network maintenance messages or application layer business interaction messages, so that users can see them clearly at a glance.

[0105] In a third aspect, the present application provides a method for building a multi-level networking system for power self-organizing network communication, characterized in that the building method includes:

[0106] Connecting a main control system, several analog terminal systems and several adjustable attenuators; the adjustable attenuators include wired adjustable attenuators and wireless adjustable attenuators;

[0107] A master node and several slave nodes are deployed on the main control system, and several slave nodes are deployed on the simulation terminal system;

[0108] The RF signals of several slave nodes on the master control system are transferred to the first RF signal convergence unit on the master control system, and the RF signals of several slave nodes on the analog terminal system are transferred to the second RF signal convergence unit on the analog terminal system; the two ends of the adjustable attenuator are respectively connected to the first RF signal convergence unit and the second RF signal convergence unit, or are respectively connected to the second RF signal convergence units of different analog terminal systems;

[0109] Determine the network form of the multi-level networking system being built; the network form includes wireless network, wired network, and wireless and wired hybrid network;

[0110] If it is a wired network, the attenuation of the wired adjustable attenuator is adjusted to the first preset range, and the attenuation of the wireless adjustable attenuator is adjusted to the second preset range; if it is a wireless network, the attenuation of the wired adjustable attenuator is adjusted to the second preset range, and the attenuation of the wireless adjustable attenuator is adjusted to the first preset range; if it is a wireless and wired hybrid network, the attenuation of at least part of the wired adjustable attenuator and at least part of the wireless adjustable attenuator are adjusted to the first preset range.

[0111] In this embodiment, the first preset range is to allow the adjustable attenuator to transmit normally and to have a certain degree of suppression, so as to build a multi-level network. The second preset range has a greater suppression effect on the signal than the first preset range, so large that the signal cannot be transmitted at all. By adjusting the attenuation amount through the adjustable attenuator, the network form is switched, so that the multi-level networking system meets the actual laboratory test needs.

[0112] like Figure 6 As shown, the specific operations of this embodiment include:

[0113] Step 1: Connect the main control system, the adjustable attenuator and the analog terminal system.

[0114] Connect 1 master control system, n analog terminal systems, and n adjustable attenuators. The master control system and one of the analog terminal systems are connected via an adjustable attenuator, and each analog terminal system is connected via an adjustable attenuator. Each master control system can be plugged with 1 master node and 8 slave nodes. Each analog terminal system can be plugged with 10 slave nodes. For example, when n is 22, a network scale of 1 master node and 228 slave nodes can be formed.

[0115] The main control system and the analog terminal system are connected to both ends of the adjustable attenuator through an SMA signal adapter cable, and the analog terminal systems are also connected to both ends of the adjustable attenuator through SMA signal connecting cables, thereby forming an environment of one main control system and multiple analog terminal systems.

[0116] Step 2: Plug the master node and slave node modules into the corresponding first and second analog terminal unit positions.

[0117] The master node module is inserted into the analog edge device unit on the main control system, and the slave node module is inserted into the first analog terminal unit on the main control system and the second analog terminal unit of the analog terminal system.

[0118] The number of master nodes is 1, and the number of slave nodes can be several, which is configured according to the test environment requirements. In addition, the slave node modules include single-phase and three-phase modules.

[0119] Step 3: The RF signal lines of the slave nodes are uniformly connected to the RF signal aggregation unit.

[0120] The main control system and the simulation terminal system both include an RF signal convergence unit, namely the first RF signal convergence unit and the second RF signal convergence unit, which transfer the RF signal from the node to the RF convergence unit. Each RF signal convergence unit is connected to a signal adjustable attenuator, which can adjust the RF signal accordingly. The adjustable attenuator is connected to the main control system or the simulation terminal system through the RF signal convergence unit.

[0121] Step 4: Determine whether the network environment is a pure wired network, a pure wireless network, or a hybrid network of wired and wireless networks. Adjust the values ​​of the wired and wireless variable attenuators as needed.

[0122] Step 5: If the built environment is purely wired, adjust the wired adjustable attenuator to NdB and the wireless adjustable attenuator to MdB. N is the first preset range and M is the second preset range. For example, the N value can be in the range of [40,70]dB and the M value can be in the range of [70,110]dB.

[0123] For example, for a network scale of 1 master node and 228 slave nodes, if the goal is to build a 5-level multi-network environment, the first level includes the slave nodes on the master control system and the slave nodes on the first two simulation terminal systems, a total of 28 slave nodes. The remaining 2nd, 3rd, 4th, and 5th levels have 50 slave nodes at each level. This embodiment only adjusts the adjustable attenuator across levels, and the adjustable attenuator between the same-level simulation terminal systems is not adjusted. Among them, the adjustable attenuator across levels, for example, is an adjustable attenuator that simultaneously connects the simulation terminal systems of the 1st and 2nd levels. If each simulation terminal system is numbered 1 to 22, the 1st and 2nd simulation terminal systems are both at the 1st level, and the 3rd to 7th simulation terminal systems are all at the 2nd level, so it is necessary to adjust the adjustable attenuator between the 2nd and 3rd simulation terminal systems. By analogy, adjust the wired adjustable attenuator between the 7th and 8th, the 12th and 13th, and the 17th and 18th simulation terminal systems. The wireless adjustable attenuators between each analog terminal system also need to be adjusted.

[0124] Step 6: If the environment is purely wireless, adjust the wired adjustable attenuator to MdB and the wireless adjustable attenuator to NdB. The N value is in the range of [40,70]dB, and the M value is in the range of [70,110]dB.

[0125] Same as step 5, if a 5-level network is built, the adjustable attenuator needs to be adjusted between the 2nd and 3rd, 7th and 8th, 12th and 13th, 17th and 18th analog terminal systems. The wired adjustable attenuator between each analog terminal system needs to be adjusted.

[0126] Step 7: If the environment is a mixture of wired and wireless, adjust the wired adjustable attenuator to NdB and the wireless adjustable attenuator to NdB.

[0127] Same as step 5, if a 5-level hybrid network is built, if the first half is a wired environment and the second half is a wireless environment, adjust the wired adjustable attenuator between the 2nd and 3rd, 12th and 13th analog terminal systems to NdB, and the wireless adjustable attenuator between the 2nd and 3rd, 12th and 13th analog terminal systems to MdB; adjust the wireless adjustable attenuator between the 7th and 8th, 17th and 18th analog terminal systems to NdB, and the wired adjustable attenuator between the 7th and 8th, 17th and 18th analog terminal systems to MdB.
