Smart meter's deployment management system and its recording media

The invention relates to a management system of a smart meter and a recording medium thereof, in particular to a deployment management system for managing a smart meter and a smart meter for maintaining communication and a recording medium thereof.

The Advanced Metering Infrastructure (AMI) is basically composed of a smart meter, a communication system, and an electric meter information management system. The main architecture includes the following:

(1) The master-slave architecture of the "back-end server-concentrator-smart meter" (Server-Master-Slave). The back end server (Server) and the concentrator (Concentrator) are connected by a Wide Area Network (WAN), and the connection method includes mobile communication technology (3G, 3.5G, 4G); Route connection (such as fiber-optic communication); or heterogeneous communication connection technology, such as back-end server connection to a power line network device, power line network device and then through Power Line Carrier (PLC) and other related power line communication (Power Line Communication) means to connect the concentrator.

The concentrator and the smart meter are connected by a local area network (LAN). Connection methods include wireless communication and wired communication, wireless communication such as: ZigBee, Near Field Communication (NFC), Bluetooth, Wi-Fi, Radio Frequency (RF) transmission; wired communication such as: Power line communication, which is narrow-band power line communication (Narrowband PLC, NPL) or broadband power line communication (Broadband PLC, BPL).

(2) The difference from the (1) architecture is that a concentrator is included between the concentrator and the smart meter. The bridge device is connected to the concentrator through a wired communication, and is connected to the smart meter in the same area or the electric meter group through the wireless communication. Wired communication such as fiber optic or BPL Such as broadband communication, wireless communication is as described above for near field communication, Bluetooth, Wi-Fi, RF transmission, etc.

However, regardless of the (1) structure or the (2) structure, the staff must have a site survey capability or a survey tool for the environment, otherwise it is difficult for the staff to find the communication quality impact of the deployment environment. Factors, if forced installation, avoid multiple communication breakpoints, resulting in a significant drop in overall communication efficiency. Moreover, if the surveying tool is not a surveying tool that is exclusively for the surveying and laying environment, the reference value of the test result is relatively low, and the final effect of the field construction and the site survey, and the expected effect of the predetermined strategy, will form a considerable Drop.

Second, the (1) architecture does not apply to more complex deployment environments. When the concentrator and the smart meter are connected by wireless communication, if there is an obstacle between the two, or when the location of the concentrator and the smart meter is not good, the smart meter is arranged in the iron meter box and the smart meter. When it is placed in the depth of the house, the location of the smart meter is too high, or it is obscured by the wall, signboard or other obstacles, it will affect the communication quality between the concentrator and the smart meter, and even cause communication interruption. In addition, in some countries' systems, the meter is forbidden to be modified. Therefore, the user or the staff cannot set the external interface of the meter antenna to form a barrier-free communication between the smart meter and the concentrator. The function of the wireless communication is equivalent.

Moreover, when the concentrator and the smart meter are connected by wired communication (commonly for narrow-band power line communication), the slave meter may be centrally installed in the power circuit of the master device, plus the reason for prohibiting the modification of the meter, the user or The staff is unable to set up the NPL integrated multi-transformer to adjust the power signal, so it is easy to cause the load imbalance of the power circuit connected to the main control device, thereby affecting the communication stability.

Third, in the case of a complicated deployment environment and a lack of a complete deployment strategy, some of the fields are being built and the test results are likely to be less than expected. The construction personnel can only choose to install the "can be installed", "the effect is not good, but the applicability is OK", but it is also easy to produce the aforementioned communication breakpoints, resulting in a lot of maintenance work in the future.

Fourthly, in terms of the (2) architecture, the installation position and space of the bridge device or circuit must be reserved in advance, and the position and wiring design of each meter must be matched when setting, which not only enhances the complexity of the circuit configuration, but also sets The method is also limited. Furthermore, bridging devices or electricity The road must be constructed on site and the construction location is usually adjacent to the meter. It is also likely to cause problems for local residents and why they should change the circuit loop.

In order to solve the above problems, the present invention discloses a deployment management system for a smart meter for managing the deployment of the deployment line and maintaining the smooth communication path between the master and the slave.

The deployment management system of the smart meter disclosed in the present invention comprises a meter group and a master device, and the meter group comprises a bridge meter and a slave meter. The master device connects the slave meter and the bridge meter via wireless communication. When the master device determines that at least one of the slave meter and the bridge meter cannot be connected, the bridge meter initiates wired communication to connect with the master device, and the bridge meter is connected to the slave meter via wireless communication.

In another embodiment, the smart meter deployment management system disclosed in the present disclosure includes a plurality of slave meters and a master device. The master device is connected to each slave meter via wireless communication. When the main control device determines that there is a problem meter in the slave meter, and the wireless device cannot communicate with the master device through the wireless communication mode, the master device first sets one of the slave meters to bridge the meter, and changes the bridge meter to wired communication and The main control unit is connected. The bridge meter is connected to the problem meter through wireless communication, and the problem meter is connected to the main control unit through the bridge meter.

The recording medium disclosed in the present invention stores a computer readable code, and a smart meter setting management method is executed when a master device, a bridge meter and a slave meter read the code, and the following steps are included. : the main control device wirelessly connects with the bridge meter and the slave meter; and when the master device determines that it cannot connect to at least one of the slave meter and the bridge meter, the bridge meter is connected to the master device by wired communication, and the bridge meter is connected Enable wireless communication for slave meter connections.

In another embodiment, the recording medium disclosed in the present invention stores a computer readable code, and a smart meter setting management method is executed when a master device and a plurality of slave meters read the code. The method includes the following steps: the main control device wirelessly connects with each slave meter; and when the master device determines that the slave meter has a problem meter that cannot be connected, set one of the slave meters to bridge the meter, and change the bridge meter to wired The communication is connected to the main control device and connected to the problem meter via wireless communication.

The system disclosed in the present invention has the following characteristics:

(1) In addition to being able to directly connect the main control device through wireless communication, the bridge meter also provides another indirect communication path, which can maintain the connection between the slave meter and the master device, and has better applicability. And convenience.

(2) When the staff does not have the capability of the site survey or the corresponding tools, the system can adjust the more suitable communication mode according to the current deployment situation, and can further provide the connection. The information of the device not only has a high reference value, but also serves as a basis for the follow-up work of the staff or the adjustment of the deployment method.

(3) Through the construction structure of bridged electricity meters and heterogeneous communication, the subordinate electricity meters can directly or indirectly communicate with the main control device, which is less affected by the residential type, house structure, terrain structure and environmental factors, and the setting of various devices. The restrictions on the points are relatively low, which not only has better applicability, but also enhances the flexibility of the overall system.

(4) The system can adjust the more suitable communication mode according to the current deployment situation. In addition to maintaining the connection between the subordinate meter and the main control device, the system can relatively reduce the staff's work on system maintenance. the amount.

(5) In some embodiments, the master device is not wired to all of the slave meters, but is wired to the bridge meter, and the bridge meter is wirelessly connected to the adjacent meter or the slave meter of the same meter group. The complexity of the built-in physical circuit is relatively low, and it is also possible to avoid the situation that the slave electric meter is installed in the power circuit of the main control device, and the load of the power circuit connected to the main control device is unbalanced, thereby maintaining communication stability.

(6) When the bridge meter is not enabled with the bridge function, its function is equivalent to the slave meter. When the bridge function is enabled, it becomes the role of the coordinator of other slave meters, and assists in transmitting the power data of other slave meters. Control device. It not only helps the switching and selection of multiple communication paths, but also eliminates the need to set up a bridge device separately, thus reducing the complexity of the line configuration. Moreover, the bridge meter has the function of the slave meter, so that the current smart meter system can be transformed into the system disclosed in the case on the premise of lower hardware equipment cost and software design cost. Furthermore, the bridge meter is built into the bridge assembly, so there is no need to reserve space for the bridge, so there is no problem of on-site construction, and it will not bother the local residents and why they have to worry about the meter circuit.

(7) When the bridge meter is not enabled for bridging, its function is equivalent to the slave meter. When the bridge function is enabled, it becomes the coordinator of other slave meters, but the wireless communication function of the slave meter is still maintained. As far as the overall system is concerned, the original wireless communication performance of the system can be exerted at a relatively high proportion, so that no component or function is useless, resulting in a significant drop in system hardware efficiency.

The embodiments of the present invention are described in detail below with reference to the drawings.

1A is a first system architecture diagram of a deployment management system for a smart meter according to an embodiment of the present invention, and FIG. 1B illustrates a first hardware configuration of a deployment management system for a smart meter according to an embodiment of the present invention. Figure. The architecture of this system is: "Backend Server 100 - Master Device 200 - Meter Group 300". The main control device 200 is the concentrator as described above. Here, for convenience of description, the "Master Device" component name is temporarily used. As described above, the back end server 100 and the main control device 200 are connected by a wide area network (WAN) or a wide heterogeneous network (WAN) and power line communication technology for communication connection; The control device 200 and the meter group 300 are connected by a local area network (LAN).

The main control device 200 includes a main control computing unit 210, a main control wired connection unit 220 and a main control wireless connection unit 230. The main control unit 210 can be an embedded system, a processor (such as a central processing unit, a microprocessor), a computing chip (Calculator Chip), an integrated circuit (IC), and a firmware ( Firmware, etc. Any of a combination of hardware, software, or a combination of software and hardware.

The master wired connection unit 220 is a network interface for transmitting data, or a power line network interface using power line carrier technology, or a similar data transmission interface. Here is a description of the power wave network interface, and broadband power line communication as an example.

The master wireless connection unit 230 is configured to perform a wireless communication connection, such as the aforementioned near field communication, Bluetooth, Wi-Fi, radio frequency, and the like. Take radio frequency (RF) communication as an example here.

The meter group 300 includes a first bridge meter 310 and a slave meter 320.

The bridge meter 310 includes a first control unit 311, a first wired connection unit 312, and a first wireless connection unit 313. The first control unit 311 is used to control the operation and data transmission mode of the first wired connection unit 312 and the first wireless connection unit 313 in addition to the power data. The first wired connection unit 312 is connected to the main wired connection unit 220 as a physical line, and therefore needs to be the same or compatible hardware specifications. Here, broadband power line communication is taken as an example. The first wireless connection unit 313 has the capability of wirelessly interconnecting with the master wireless connection unit 230. Therefore, the same or compatible hardware specifications are required. Here, radio frequency communication is taken as an example.

The slave meter 320 has a slave wireless connection unit 323 that is associated with the first wireless The connection unit 313 and the master wireless connection unit 230 are the same or compatible hardware specifications, and RF communication is also taken as an example here.

The master device 200, the bridge meter 310, and the slave meter are 320 wireless communication ranges between each other. When the system is started, the master device 200, the bridge meter 310, and the slave meter 320 perform a connection operation with each other. The slave meter 320 enables the slave wireless connection unit 323 to transmit wireless signals to find a coordinator that is connectable and can assist in logging into the network. The first control unit 311 also enables the first wireless connection unit 313 to transmit wireless signals to find a coordinator that can be connected and can assist in logging into the network. The master computing unit 210 then enables the master wireless connection unit 230. The master device 200 is a central point of attachment device that connects the backend server 100 to the meter group 300.

In some embodiments, the master device 200 establishes a wireless connection with the bridge meter 310 and the slave meter 320, and obtains the power information provided by the bridge meter 310 and the slave meter 320. The success of the wireless connection is whether the bridge meter 310 and the slave meter 320 can complete the network login operation through the master device 200 within a preset time. Further, factors such as the number of data transmission errors, the degree of signal interference, and the number of times the signal is not responded can be considered. Wherein, if the master device 200 can be wirelessly connected to the bridge meter 310, there is no difference between the function of the bridge meter 310 and the slave meter 320.

The main control device 200 stores device information of the bridge meter 310 and the slave meter 320, and the bridge meter 310 and the slave meter 320 are disposed adjacent to each other. When the main control unit 210 determines that the connection between the slave meter 320 and the bridge meter 310 cannot be established, the master wired connection unit 220 is enabled, the bridge meter 310 is connected in a wired manner, and the bridge meter 310 is commanded. Enable bridging. When the first control unit 311 obtains the command of the master device 200, the related function of the first wired connection unit 312 is enabled. The first wired connection unit 312 forms a wired connection with the master wired connection unit 220, so that wired communication is formed between the master device 200 and the bridge meter 310, which is, for example, broadband power line carrier communication. On the other hand, the first control unit 311 adjusts the operation mode of the first wireless connection unit 313, cuts off the wireless connection with the main control device 200, and forms a mode of operation such as a wireless access point or a concentrator. For the slave meter 320 to connect. When the slave wireless connection unit 323 finds the bridged power meter 310, it will wirelessly connect with the bridge meter 310. The bridge meter 310 becomes the master device A bridge between the slave 200 and the slave meter 320 establishes an indirect communication path between the master device 200 and the slave meter 320.

In some embodiments, the bridge meter 310 can actively determine the connection state, that is, when the first control unit 310 determines that the master device 200 cannot be wirelessly connected, the bridge function is directly enabled to be wired. The main control device 200 is connected in a manner.

In addition, referring to FIG. 1B, the bridge meter 310 between the meter groups 300 may also be connected by wired communication or wireless communication. In other words, the master device 200 can establish a communication path with the slave meter 320 via more than one bridge meter 310.

Configuration diagram. The foregoing meter group 300 further includes a bridge standby meter 330, which includes a second control unit 331, a second wired connection unit 332 and a second wireless connection unit 333. The component functions and operates in the same manner as the bridge meter 310.

When the master device 200 determines that the connection between the bridge meter 310 and the slave meter 320 cannot be established, the bridged standby meter 330 is commanded to enable the bridge function. The second control unit 331 activates the second wired connection unit 332 when acquiring the command of the master device 200. The second wired connection unit 332 forms a wired connection with the master wired connection unit 220 such that wired communication is formed between the master device 200 and the bridged standby meter 330. On the other hand, the second control unit 331 adjusts the operation mode of the second wireless connection unit 333, cuts off the wireless connection with the main control device 200, and forms a mode of operation such as a wireless access point or a concentrator for bridging the electric meter. 310 is connected to the slave meter 320. When the first wireless connection unit 313 and the slave wireless connection unit 323 find the bridged standby power meter 330, they are wirelessly connected to the bridged standby power meter 330. The bridged standby meter 330 becomes a bridge between the master device 200 and other meters.

Configuration diagram. The slave meter 320 further includes a slave wired connection unit 322 having a specification corresponding to the master wired connection unit 220 and forming a connection of the physical line. In some embodiments, the specifications of the slave wired connection unit 322 and the master wired connection unit 220 conform to power line carrier communication, such as broadband power line carrier communication or narrow frequency power line carrier communication, but common It is a narrow-band power line carrier communication. Therefore, in combination with the foregoing embodiments, the master device 200 and the slave meter 320 include at least the following forms of interaction:

(1) When the master device 200 can wirelessly connect to the slave meter 320, it communicates directly with the wireless connection.

(2) When the master device 200 determines that the slave meter 320 cannot be wirelessly connected, the master wired connection unit 220 and the slave wired connection unit 322 form wired communication.

(3) When the master device 200 determines that the slave meter 320 is still unable to communicate with the slave meter 320, the master wired connection unit 220 is used to form wired communication with the slave wired connection unit 322.

(4) When the slave meter 320 continues to judge that no device can be found for wireless communication, the slave wired connection unit 322 is enabled to form wired communication with the master wired connection unit 220.

(5) When the slave meter 320 finds the master device 200 and the bridge meter 310 at the same working time through the slave wireless connection unit 323, it determines the connection quality with the bridge meter 310 and the connection quality with the master device 200, What are the advantages and disadvantages. When the slave meter 320 determines that the connection quality with the bridge meter 310 is higher than the connection quality with the master device 200, the bridge meter 310 is connected.

(6) With respect to the point (5), when the slave meter 320 determines that the connection quality with the bridge meter 310 is lower than the connection quality with the master device 200, the master device 200 is connected.

(7) The main control device 200 presets to connect to the slave electric meter 320 by wire to perform wired communication. The slave meter 320, such as a single order, can be deployed in this manner.

(9) When the bridge meter 310 determines that the master device 200 cannot be wirelessly connected, the master device 200 is wired, and the bridge meter 310 is wirelessly connected to the other slave meters 200 to form the master device 200 and the slave meter 320. Indirect communication.

In some embodiments, in the system disclosed in FIG. 1A to FIG. 3B, the main control device 200 records the hardware information of the electric meter group. When the main control device 200 is wired to connect the bridge 310, it is still not When communicating with the slave meter 320, the master computing unit 210 will indicate the hardware information of the slave meter 320 (a problem meter to be described later). The main control device 200 can transmit the hardware information of the marked slave electric meter 320 to the backend server 100 as reference information for the deployment personnel to adjust the deployment mode. Similarly, when the master device 200 is unable to communicate with the bridge meter 310, the master computing unit 210 will indicate the hardware information of the bridge meter 310 (a problem meter to be described later). The main control device 200 can transmit the hardware information of the marked bridged electrical meter 310 to the backend server 100 as reference information for the deployment personnel to adjust the deployment mode.

Continuing to refer to FIG. 4 is a schematic diagram of a fourth system architecture of a deployment management system for a smart meter according to an embodiment of the present invention. The meter group 300 includes a plurality of slave meters 320, and the slave meters 320 include a plurality of problem meters 340 as previously described. Each of the problem meters 340 can be replaced with a test bridge meter 350 (functioning as described above for the bridge meter 310, here using different component names), and the replacement method is also not limited, and the slave meter 320 can belong to the bridge meter 310. The type of meter is either tested by the fabric personnel one by one. The main control device 200 separately generates a connection status information according to the connection condition of the bridged electric meter 350 and the adjacent problem meter 340 in the same electric meter group 300, and provides all the connection status information to the rear. End server 100. Based on the connection status information, the backend server 100 calculates where the problem meter 340 needs to be replaced with the bridge meter 310, thereby generating more than one deployment modification scheme for the reference personnel, or The appropriate solution is selected by the backend server in accordance with the predetermined design. However, the conditions for the installation modification scheme include: (1) after the replacement bridge meter 310, all the problem meters 340 can directly or indirectly communicate with the main control device 200; (2) each problem meter 340 can stably perform data Transmission, at least for a preset time, can complete the network login operation through the master device 200; (3) the number of replacements of the bridge meter 310 is the least; (4) when the number of replacements of the bridge meter 310 is the same, The best solution for data transmission.

Please also refer to Figure 5 for a schematic diagram of the problem meter layout. Among them, this meter group has 8 problem meters (340a, 340b, 340c, 340d, 340e, 340f, 340g, 340h). Each problem meter (340a, 340b, 340c, 340d, 340e, 340f, 340g, 340h) is gradually replaced with a test bridge meter 350, one or more at a time. The master device 200 transmits the connection condition of the test bridge meter 350 to the other problem meter to the backend server 100 for the backend server 100 to generate a plurality of deployment correction schemes. When the scheme is constructed, the bridge meter 310 can cover the most The multi-issue meter is preferred, for example, the problem meter 340b and the problem meter 340f. However, when a problem meter cannot be connected to the test bridge meter 350 of other replacement points, such as the problem meter 340d, the problem meter 340d is separately replaced as one of the choices of the bridge meter 310.

However, in some embodiments, the deployer can also use the slave meter 320 in the same meter group 300 as an alternative, and is not limited to the technical implementation shown in FIGS. 4 and 5.

6 is a schematic diagram showing a fifth system architecture of a deployment management system for a smart meter according to an embodiment of the present invention. The difference between that shown in FIG. 1 is that the meter group 300 includes a plurality of slave meters 320. The functions of the slave meters 320 are identical or similar to those of the bridge meter 310. For convenience of explanation, the slave meter 320 is still used as the component name. Description. In this example, each slave meter 320 includes a slave wireless connection unit 323 and a slave wired connection unit 322.

When the system is running, between the master device 200 and the slave meter 320, the master wireless connection unit 230 and the slave wireless connection unit 323 perform wireless communication first. When the main control device 200 determines that there is a problem meter 340 in the slave meter 320, that is, wireless communication with the problem meter 340 is not possible, the master wired connection unit 220 is enabled, and the slave meter 320 is selected (may also be the problem meter 340 described above). It is connected to the physical line by the slave wired connection unit 322, and the selected slave meter 320 is the bridge meter 310 of the foregoing embodiment. The main control device 200 and the slave electric meter 320 communicate with each other through a narrow-band power line communication method or a broadband power line communication method. However, in addition to the slave meter 320 that is wired by the master device 200, it may also be one of the preset bridge functions in the slave meter 320. Once the slave meter 320 of the preset function determines that the master device 200 cannot be connected, That is, the master device 200 is connected in a wired manner and serves as a bridge device for the other slave meters 320.

In some embodiments, when the master device 200 determines that it cannot connect to the problem meter 340, there are at least the following modes of operation:

(1) When the main control device 200 determines that the problem cannot be connected to the problem meter 340 through the wireless communication, first try to set the bridge meter 310 from the other slave meters 320, and change the bridge meter 310 to the wired communication and the master device 200. connection. The bridge meter 310 is connected to the problem meter 340 via wireless communication.

(2) When the master device 200 determines that the wireless communication and the problem meter 340 cannot be transmitted When connected, it will be connected to the problem meter 340 by wired communication. In some embodiments, the master device 200 sets the problem meter 340 to bridge the meter 310 and causes the bridge meter 310 to be connected to the slave meters 320 via wireless communication.

(3) When the main control device 200 determines that the problem cannot be connected to the problem meter 340 through the wired communication, the other slave meter 320 is alternatively set to the bridge meter 310, and the bridge meter 310 is connected to the master device 200 by wired communication. The problem meter 340 is connected via wireless communication. The difference from the previous one is when the bridge mode is enabled.

(4) When the master device 200 sets each of the slave meters 320 to be the bridge meter 310 and cannot connect to the problem meter 340, the master device 200 is further connected to the problem meter 340 by wired communication.

However, when the slave meters 320 determine that they can be simultaneously connected to the master device 200 and the bridge meter 310, the quality of the two communication paths is first determined. When the slave meter 320 determines that the quality of the connection with the bridge meter 310 is higher than the quality of the connection with the master device 200, the bridge meter 310 is connected. Conversely, when the slave meter 320 determines that the quality of the connection with the bridge meter 310 is lower than the quality of the connection with the master device 200, the master device 200 is connected. This applies to the slave meter 320 of FIGS. 1 through 6 described above.

Similarly, when the meter group 300 has a plurality of problem meters 340, the layout modification scheme can be generated according to FIG. 4 and FIG. 5, which will not be described herein.

In addition, the foregoing type of the bridge meter 310 and the slave meter 320 are not limited, and a combination of the same, similar or different meter types of single phase, three phase, high voltage, low voltage, etc. may be employed.

Please refer to FIG. 7 , which is a schematic diagram of the site layout of the deployment management system of the smart meter according to the embodiment of the present invention. Please also cooperate with Figure 1 to Figure 6 to facilitate understanding. There are two types of on-site deployment, one for site survey and one for site survey.

When a site survey is carried out, the deployer uses the survey tool corresponding to the environment for site survey. For example, it is more appropriate to determine that the slave meter 320 in the 4th, 5th, and 6th regions uses wired communication, that is, using narrow-band power line communication. Line representation). The slave meters 320 of the first, second, and third regions are not suitable for wireless communication, that is, the slave meters 320 of the respective regions are gradually replaced, and an appropriate bridge meter 310 replacement scheme is selected. As shown in FIG. 7, the third area needs to be independently configured with a bridge. In the electric meter 310, the first and second regions only need to arrange a bridge meter 310 in the second region for wireless connection (indicated by a broken line) of the other slave meters 320 of the first and second regions.

On the other hand, when there is no site survey, the deployers can build according to their own experience according to the system architecture shown in Figure 1 or Figure 6. When the system is enabled, it will spontaneously construct the appropriate communication path in the way that the maximum path is connected as much as possible, and mark the meter that cannot be connected at all. The construction personnel only need to establish a solution for the problem meter.

Electric meter 320. As previously described, when the master device 200 determines that it is unable to connect to the slave meter 320 of a certain meter group 300, the bridge meter 310 of the same meter group 300 is commanded to enable the bridge mode, such that the master device 200 and the slave meter 320 Indirect communication can occur between one or more bridged meters 310. However, when communication is still not possible, depending on the line design, the master device 200 can enable the bridged standby meter to enable the bridge mode or directly connect to the slave meter 320. However, when the above communication methods are not available, the construction personnel need to go to the site for testing and maintenance. In addition, the bridge meter 310 can also be any number in the corresponding group, and is not limited. Furthermore, if it is combined with FIG. 6, the meter group 300 can also be composed of a slave meter 320 having a bridge function.
