Detailed Description
Embodiments of the invention are described in detail below with reference to the attached drawing figures, but the invention can be practiced in a number of different ways, as defined and covered below.
As shown in fig. 2, a preferred embodiment of the present invention provides an end-side device of an electric power mining system, including a plurality of electric meters and a meter box terminal configured in a meter box, in which a first bluetooth module and a metering chip are configured in each other, a second bluetooth module, a carrier communication module and a processing chip are configured in the meter box terminal, the second bluetooth module and the carrier communication module are both connected with the processing chip, data interaction is performed between the plurality of electric meters and the meter box terminal through the first bluetooth module and the second bluetooth module, the meter box terminal performs data interaction with an edge side terminal through the carrier communication module and then with a master station, the processing chip creates a virtual container for each electric meter in the meter box according to a box table relationship, and configures a virtual management core in the virtual container, and all interactions with the electric meters are distributed to the corresponding virtual management cores by the processing chip, and transferred to the metering cores of the electric meters through bluetooth communication.
It can be understood that the adoption process of the end-side device is as follows: each ammeter wirelessly transmits the collected data to the meter box terminal through Bluetooth communication, and then the meter box terminal uniformly uploads the collected data through the carrier communication module. In addition, the electric meter is a single-core meter, the management cores of the traditional double-core meter are functionally moved to the meter box terminal to be uniformly realized, and the meter box terminal is configured with a virtual management core for each single-core meter based on container technology and function mirror image. Specifically, the management core code of the original double-core meter is transplanted to the processing chip of the meter box terminal, the interface between the original management core and the metering core is modified to be a Bluetooth interface, and a management core function mirror image is generated for the processing chip of the meter box terminal. The meter box terminal acquires and records a box meter relationship, namely the membership of the ammeter relative to the meter box. When the software system of the meter box terminal is started, the meter box terminal creates virtual management cores for a plurality of electric meters in the meter box one by one according to the box table relation, and the creation result of the virtual management cores is shown in fig. 3. For example, after the meter box terminal is started, a container 1 is created for the ammeter 1 in the meter box, a corresponding management core function mirror image is started in the container 1, and because the container is provided with independent processor resources and internal and external memory storage resources, the management core function in the container 1 is loaded on an independent management core, and can be logically regarded as a virtual management core. Then, the meter box terminal binds the virtual management core 1 with the electric meter 1 to form a virtual double-core meter 1, the virtual double-core meter has the address of the electric meter 1, all management function interactions with the electric meter 1 can be distributed to the virtual management core 1 in the container 1 by the processing chip, and then the virtual management core 1 is transferred to the metering core of the electric meter 1 through Bluetooth communication, so that interaction with the electric meter 1 is completed. Therefore, the virtual double-core table design of the invention uses the virtualization design, thereby greatly reducing the cost of use, retaining the logic and data interfaces of the original double-core table, ensuring the independent operation between the virtual double-core tables and having high popularization value.
It will be appreciated that the bin table relationship may be obtained by manual configuration or by an automatic identification technique which may be implemented using 485 wire identification or bluetooth 5.1 homing function. However, manual configuration is time-consuming and labor-consuming and is prone to error, and 485 wiring identification is prone to causing confusion of wiring in the meter box, affecting daily operation and maintenance work and bringing about certain potential safety hazards. Therefore, the invention preferably adopts the bluetooth 5.1 direction finding function to automatically identify the box table relation. At present, the bluetooth 5.1 direction finding function mainly adopts two positioning technologies, namely an Angle of Arrival (AOA) technology and an Angle of departure (Angle or Departure, AOD) technology. In the invention, the AOA technology adopts one transmitting antenna and a plurality of receiving antennas, and the AOD technology adopts a plurality of transmitting antennas and one receiving antenna. Specifically, the meter box terminal is configured with a plurality of antennas, the electric meter is configured with a single antenna, the meter box terminal sequentially transmits Bluetooth broadcast signals through the plurality of antennas, and the electric meter calculates the direction and the distance of the electric meter relative to the meter box terminal according to the received Bluetooth broadcast signals, so that the box table relation is obtained.
It can be understood that, for the selection of the container technology, if the processing chip of the table box terminal is loaded with a Linux system, the LXC or dock technology is adopted to configure the virtual container; and if the processing chip of the table box terminal is provided with an embedded system, configuring a virtual container by adopting a sandbox technology in an embedded Java virtual machine.
It can be understood that, in the end-side device of this embodiment, each electric meter adopts a single-core design, only one metering chip is configured, and no management chip is configured, and a virtual management core is configured for each electric meter separately based on the container technology and the mirror image function through the processing chip of the meter box terminal, and the management function of each electric meter is executed by the virtual management core, and each container has independent processor resources and internal and external storage resources, so that each virtual management core is independent of each other, as an entity management core, the configuration cost of the electric meter is reduced, the rational utilization of resources is realized, and the problem of resource waste in the existing end-side device is effectively solved. And carry out wireless communication through bluetooth between ammeter and the table case terminal to low-cost bluetooth module has replaced the HPLC module of high cost, has reduced the cost of ammeter by a wide margin, uses the HPLC module in the table case terminal to unify the data of adopting of all ammeter in the table case simultaneously, can reduce node number and the total number of message in the HPLC network of adopting the system by a wide margin, is showing the transmission efficiency who promotes the HPLC network, has reduced the fault rate.
It will be appreciated that at least two meter boxes in close geographic proximity may form a meter box association, only one meter box in the meter box association being configured with meter box terminals, the only one meter box terminal in the meter box association performing virtual management core configuration for a plurality of electricity meters in the entire meter box association. For example, a plurality of cases having a distance from each other smaller than a threshold value whose value range is set according to the effective communication range of bluetooth may constitute a case combination. The meter box combination is formed by at least two meter boxes which are close to each other, the acquired data of all the electric meters in the meter box combination are converged into a unique meter box terminal through a Bluetooth channel, and then are uniformly uploaded through a carrier communication module of the meter box terminal. The combined setting of the meter box can greatly reduce the number of meter box terminals in the acquisition system, further save the cost and reduce the node number and the total number of messages in the HPLC network.
It will be appreciated that in existing power grid deployment systems, cloud, edge, end architecture implementations are typically employed, including a power grid cloud platform (e.g., a power grid master station, etc., hereinafter collectively referred to as a master station), edge side acquisition devices (e.g., an energy controller, a convergence terminal, a concentrator, etc., hereinafter collectively referred to as an ECU), and end side metering devices (e.g., an electricity meter, etc., hereinafter collectively referred to as an electricity meter), the entire communication link being divided into an uplink between the ECU and the master station and a local link between the ECU and the electricity meter. The uplink is mainly a 4G wireless virtual private network provided by a telecom operator at present, the local link is mainly a power line carrier network (HPLC), in actual operation, the power line carrier network is affected by various uncertain factors, the carrier line is temporarily invalid, at the moment, a master station cannot collect power data on the invalid line, meanwhile, control information issued from the master station cannot be issued to an ammeter on the invalid line in time, and the problem caused by the reliability of the carrier network brings great inconvenience to power grid companies and users. The invention solves the reliability problem of the existing HPLC network by adopting the mode of regional alliance and link backup, and greatly improves the data acquisition success rate of the acquisition system.
Specifically, in other embodiments of the present invention, a meter box or a meter box terminal in a meter box combination and a plurality of electric meters may form a box meter subnet, and a plurality of box meter subnets may form an area alliance, where a bluetooth mesh technology is used for networking in the area alliance, each area alliance has a unique ID, and the phase, the area alliance ID, and information of each node in the subnet of each box meter subnet are reported to the master station by the meter box terminal in the box meter subnet, where the master station communicates with the electric meters through the meter box terminal in the box meter subnet in which the master station is located. The information of each node in the subnet comprises address information of each node, ID of the node and the like. The generation process of the regional alliance ID specifically comprises the following steps: the IDs of all the table box terminals in the regional alliance are spliced in order from small to large, and then a hash value of the splicing value is calculated, wherein the hash value is the ID of the regional alliance. Although the IDs of the individual table box terminals in the different area alliances may be repeated in an extreme case, the IDs of all the table box terminals in each area alliance are spliced in order from small to large, the splicing result is impossible to be repeated, and on the basis, the calculated hash value is unique. By constructing the regional alliance, once a meter box terminal in a certain box meter sub-network fails, for example, a carrier line of a phase where the certain meter box terminal is located fails, as a plurality of box meter sub-networks in the regional alliance are networked by a Bluetooth mesh technology, data can be communicated and transmitted in the regional alliance by Bluetooth, and thus, the meter box terminal which is not failed by other carrier lines in the regional alliance can be searched for auxiliary communication or substitute communication.
And in the communication process, the master station and each meter box terminal count the communication performance states between the master station and each meter box terminal according to the period, and evaluate whether to search for the proxy communication node according to the communication performance states. For example, the master station and the first meter box terminal count the communication performance states between the master station and the first meter box terminal according to the period, if the master station and the first meter box terminal are in a low communication performance state, the initiator of interaction selects a second meter box terminal with different phases and/or in a high communication performance state in the regional alliance where the first meter box terminal is located as a proxy meter box terminal, and the proxy meter box terminal proxies the communication between the master station and the first meter box terminal. The data collected by all the electric meters in the box meter sub-network where the first meter box terminal is located can be sent to the proxy meter box terminal through the Bluetooth channel, and then the data is sent up through the carrier communication module of the proxy meter box terminal, so that the backup of the invalid (low-efficiency) HPLC link is realized by using the Bluetooth+high-efficiency HPLC link, and the reliability of the whole HPLC network is ensured.
The method comprises the steps that a communication performance state is evaluated by adopting a last successful interaction rate and a last interaction state as communication performance indexes, wherein the last interaction state comprises the number of times used by last interaction and total duration used by interaction, and if the success rate of the last interaction between a master station and a meter box terminal is lower than a first threshold value, or the number of times used by last interaction and the total duration used by interaction are both higher than a second threshold value, the master station and the meter box terminal are in a low communication performance state; if the success rate of one interaction between the master station and the meter box terminal is higher than a third threshold value, and the number of times used for the last interaction and the total duration used for the interaction are both lower than a fourth threshold value, the master station and the meter box terminal are in a high communication performance state.
It can be understood that the value of the success rate of one interaction is the ratio of the number of successful interactions of the master station and the first table box terminal in the period to the total number of interactions, which can represent the overall performance index in one statistical period, and the last interaction state is the single-point performance index. The threshold values can be set according to the requirements according to different indexes, wherein the first threshold value is smaller than the third threshold value, and the second threshold value is larger than the fourth threshold value. For example, the first threshold may be set to 30% for one interaction, the third threshold may be set to 80% for the number of last interactions, the second threshold may be set to 3, the fourth threshold may be set to 1, the second threshold may be set to 60 seconds for the total duration of last interactions, and the fourth threshold may be set to 10 seconds. The above threshold setting is merely exemplary and is not specifically limited herein.
In addition, when the proxy time of the proxy meter box terminal exceeds the preset timeout time, the communication between the master station and the first meter box terminal is switched back to the original state, so that the influence on the communication caused by the overlong proxy time of the proxy meter box terminal is prevented.
It will be appreciated that another embodiment of the present invention also provides an electrical power recovery system employing an end side apparatus as described above.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art.
