Background
In recent years, the construction of low-voltage meter reading of domestic power systems gradually realizes full coverage. The low-voltage centralized meter reading local communication technology is rapidly developed.
The field communication of low-voltage meter reading is realized mainly by constructing a field communication bus by the concentrator and a local communication module of the electric meter. The field bus of the low-voltage centralized meter reading has the application of communication technologies such as an R485 bus, a narrow-band Power Line Carrier (PLC), a micro-power wireless (RF), a micro-power + power line carrier dual mode (RF + PLC), a Broadband Power Line Carrier (BPLC), a high-speed power line carrier (HPLC), a CAN and the like.
At present, interconnection communication interface protocols are established in micropower wireless and broadband power line carrier technologies respectively, and plug and play and interchange of communication modules can be realized.
However, the existing low-voltage centralized meter reading local communication technologies, including the R485 bus communication technology and the narrowband Power Line Carrier (PLC) communication technology, cannot realize interconnection, have poor transmission rate and stability, and are difficult to meet the increasing data and service expansion requirements.
Communication modules between manufacturers cannot be interconnected, intercommunicated and interchanged, a barrier between station areas is formed, difficulty is caused to installation, debugging and operation maintenance of field equipment, the condition that the communication technology generated by load adjustment between adjacent station areas is mixed in the same station area is very common, and data acquisition application of a low-voltage centralized meter reading system is seriously influenced.
In the existing low-voltage centralized meter reading system, communication schemes between a concentrator and a meter are diversified, the communication technical schemes of communication module manufacturers are basically independently researched and developed, a uniform technical standard does not exist, the situation that the communication schemes cannot be compatible is caused, and great difficulty is caused to operation and maintenance management of a transformer area.
In particular, the prior art has the following drawbacks:
the low-voltage meter reading system is built for a long time, various technical systems coexist, various field buses such as RS485, PLC, micro-power wireless and the like coexist in one platform area, a platform area concentrator and an ammeter are difficult to be compatible with different ammeter communication modules, and the existing communication modules cannot be used for replacing the platform area storing the quantity, so that the field operation and maintenance are difficult.
Communication modules between different manufacturers adopting the same technical system cannot realize interconnection and interchange because the communication networking protocols are not completely consistent, so that a barrier between the station area management is formed, and difficulty is caused to installation, debugging and operation maintenance of field equipment.

Detailed Description
Referring to fig. 1, fig. 1 is a schematic diagram of a typical structure of a field data communication bus of a low-voltage station area, as shown in fig. 1, generally, a station area uses a concentrator, and uses a three-phase power line carrier module (e.g., a three-phase PLC) to perform data communication with a single-phase power line carrier module (e.g., a single-phase PLC) of an electric meter. Typically, the concentrator is connected to A, B, C, N three-phase four wires of a power line, the electricity meter is connected to the phase and neutral wires, and the communication data is transmitted over the power line.
The process of the metering master station collecting the electric meter data is shown in fig. 2. The metering master station issues the data acquisition instruction to the concentrator, a PLC communication network is established between the concentrator and the PLC of the electric meter through a networking protocol, then the acquisition instruction of the metering master station is translated into 645 messages which can be identified by the electric meter, and the 645 messages are transmitted on the power line in a broadcasting mode. After receiving the broadcast message, the electric meter identifies the address of the electric meter, then responds to the 645 message, and after receiving the 645 message, the concentrator analyzes and temporarily stores the data and then transmits the data back to the metering master station.
In practical situations, usually in the initial stage of the district construction, the three-phase carrier module of the concentrator and the single-phase carrier module of the electric meter are of the same manufacturer and the same model, and the problem of interconnection does not exist. As shown in fig. 3, fig. 3 is a schematic diagram of a conventional heterogeneous PLC bus structure. With the gradual operation and maintenance of the transformer area, the load adjustment of the adjacent transformer areas and the maintenance and replacement of the communication modules of the electric meters, the system of the communication modules in the same transformer area will change. At this time, a single concentrator cannot communicate with the electric meters of different communication modules (for example, PLC1 and PLC2 in fig. 3 represent communication modules of different standards), so that data of the electric meters newly added to the station area cannot be collected. In addition, the workload of on-site troubleshooting of the electric meter is huge, and data reading cannot be timely and effectively carried out.
The embodiment of the invention provides an ammeter data acquisition method, an ammeter data acquisition device, ammeter data acquisition equipment and a storage medium, which are used for solving the technical problem that a barrier between station area management is formed and data acquisition application of a low-voltage meter reading system is influenced due to the fact that different communication modules cannot be interconnected, communicated and exchanged.
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the embodiments described below are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 4, fig. 4 is a flowchart illustrating steps of a method for collecting data of an electric meter according to an embodiment of the present invention.
The invention provides an ammeter data acquisition method, which is applied to a low-voltage centralized meter reading system, wherein the low-voltage centralized meter reading system comprises a metering master station, a master concentrator, a slave concentrator and a plurality of ammeters; the plurality of electric meters comprise a master electric meter and a slave electric meter; the concentrator is a central management device and a control device of a remote centralized meter reading system and is responsible for regularly reading terminal data, transmitting system commands, communicating data, managing a network, recording events, transversely transmitting data and the like. The ammeter is short for the electric energy meter. An electric energy meter is an instrument for measuring electric energy, also called watt-hour meter, fire meter, kilowatt-hour meter, and refers to instruments for measuring various electric quantities.
The specific method can comprise the following steps:
in the embodiment of the invention, when the main concentrator receives the acquisition instruction issued by the metering master station, the data of the corresponding main electric meter is acquired through the main three-phase PLC in the main concentrator based on the acquisition instruction.
It should be noted that the master concentrator and the master meter have the same communication module, so that data interaction between the two is possible. When the main concentrator collects ammeter data through the main ammeter, networking with the main ammeter is required to be performed first, and network connection between the main concentrator and the main ammeter is established.
it should be noted that the acquisition instruction issued by the metering master station may include acquiring the meter data of the slave meters, and therefore, when the acquisition instruction is received, it needs to be analyzed whether to forward the acquisition instruction to the slave concentrator.
when the electric meter data of the slave electric meter needs to be collected, the collection instruction is forwarded to the slave concentrator, so that the electric meter data of the slave electric meter can be collected through the slave concentrator. After the ammeter data are collected from the concentrator, the ammeter data need to be transmitted to the main concentrator for storage.
And 405, uploading the main ammeter data and the auxiliary ammeter data to the metering master station when receiving a meter reading instruction issued by a preset metering master station.
The main concentrator and the main metering station are in direct communication, and when receiving a meter reading instruction issued by the main metering station, the main concentrator can upload the stored main ammeter data and the stored slave ammeter data to the main metering station.
It should be noted that the method according to the embodiment of the present invention is implemented on the basis of the structure of fig. 5, and fig. 5 is a schematic diagram of a master-slave interconnection structure of a multi-concentrator according to the embodiment of the present invention. As shown in fig. 5, the master concentrator and the slave concentrator respectively use a three-phase power line carrier module (e.g., a three-phase PLC) to perform data communication with a single-phase power line carrier module (e.g., a single-phase PLC) of the electric meter. Typically, the concentrator is connected to A, B, C, N three-phase four wires of a power line, the electricity meter is connected to the phase and neutral wires, and the communication data is transmitted over the power line. Meanwhile, the master concentrator and the slave concentrator are connected through an RS485 bus.
According to the invention, the master concentrator and the slave concentrator are introduced into the low-voltage centralized meter reading system, so that electric meters with different communication systems can be respectively networked with the master concentrator and the slave concentrator with the same communication system, and accordingly, electric meter data of corresponding electric meters are respectively collected through the master concentrator and the slave concentrator. Furthermore, the slave concentrator communicates with the metering master station via the master concentrator, so that no modifications to the metering master station are required.
For ease of understanding, please refer to fig. 6, fig. 6 is a flowchart illustrating steps of a method for collecting data of an electric meter according to another embodiment of the present invention. The method specifically comprises the following steps:
601, broadcasting a main PLC networking instruction to a plurality of electric meters through a main three-phase PLC;
PLC is a programmable logic controller, which is a digital arithmetic operation electronic system designed specifically for use in an industrial environment. It uses a programmable memory, in which the instructions for implementing logical operation, sequence control, timing, counting and arithmetic operation are stored, and utilizes digital or analog input and output to control various mechanical equipments or production processes.
In the embodiment of the invention, the main concentrator is provided with the communication module main three-phase PLC, and the main three-phase PLC can broadcast a main PLC networking instruction to the electric meter in a broadcasting mode.
It should be noted that, in practical applications, the communication module may not only select a three-phase PLC, but also select another communication module, and the present invention is not limited to this.
in the embodiment of the invention, the electric meters with the same communication modules as the main concentrator can be connected with the main concentrator according to the received main PLC networking instruction. Thus, it is possible to define the electricity meter establishing a connection with the primary concentrator as the primary meter and to record the affiliation between the primary concentrator and the primary meter.
in the embodiment of the invention, the master concentrator can issue a networking notice to the slave concentrator at regular time, notify the slave three-phase PLC module of the slave concentrator to initiate ad hoc network with the slave electric meter, and determine the attribution relationship between the slave concentrator and the slave electric meter.
in the embodiment of the invention, when the main concentrator receives the acquisition instruction issued by the metering master station, the data of the corresponding main electric meter is acquired through the main three-phase PLC in the main concentrator based on the acquisition instruction.
In one example, step 607 may include:
translating the acquisition instruction to obtain a 465 message, and sending the 465 message to a main ammeter through a main three-phase PLC;
receiving the master meter data returned by the master meter based on the 465 message.
Specifically, when the metering master station issues an acquisition instruction to the main three-phase PLC of the main concentrator, the main three-phase PLC transfers the acquisition instruction into a 465 message according to a self networking result and sends the 465 message to the main ammeter; and after the main ammeter collects ammeter data based on the 465 message, returning the collected ammeter data to the main concentrator.
since the master concentrator can only collect the master meter data, when the meter data of the slave meters needs to be collected, the collection instruction needs to be forwarded to the slave concentrators so that the slave concentrators can collect the data of the slave meters.
In one example, determining whether to forward the gather instruction to the slave concentrator may be accomplished by:
and judging whether to forward the acquisition instruction to the slave concentrator or not according to the first networking result and the second networking result.
Specifically, whether to forward the collecting instruction to the slave concentrator for corresponding electric meter data collection can be judged according to whether to collect the electric meter data of the slave electric meters.
it should be noted that, as for the method for acquiring the meter data of the slave meters from the concentrator, reference may be made to a method for acquiring the number of meters of the master meter by using the master concentrator, and details thereof are not repeated herein.
After the corresponding electric meter data are collected by the slave concentrator, the relevant data can be sent to the master concentrator for storage.
And step 610, uploading the main ammeter data and the auxiliary ammeter data to the metering master station when receiving a meter reading instruction issued by a preset metering master station.
The main concentrator and the main metering station are in direct communication, and when receiving a meter reading instruction issued by the main metering station, the main concentrator can upload the stored main ammeter data and the stored slave ammeter data to the main metering station.
According to the invention, the master concentrator and the slave concentrator are introduced into the low-voltage centralized meter reading system, so that electric meters with different communication systems can be respectively networked with the master concentrator and the slave concentrator with the same communication system, and accordingly, electric meter data of corresponding electric meters are respectively collected through the master concentrator and the slave concentrator. Furthermore, the slave concentrator communicates with the metering master station via the master concentrator, so that no modifications to the metering master station are required.
For ease of understanding, please refer to fig. 7, fig. 7 is a schematic diagram illustrating a master-slave interconnection data collection of a multi-concentrator according to an embodiment of the present invention. For the collection of meter data, the following steps can be included:
1. the master concentrator sends a networking notice to the slave concentrators at regular time, and the slave three-phase PLC of the slave concentrators is notified to initiate an ad hoc network;
2. the slave concentrator issues a networking instruction to the slave three-phase PLC according to the received networking notification;
it should be noted that the networking process is realized by the PLC itself, and the concentrator is not aware of the process, but only knows the networking result.
3. The slave concentrator feeds the networking result back to the master concentrator;
4. the main concentrator issues a PLC networking instruction, and records the attribution of the electric meter according to the feedback result of the electric meter;
5. the metering master station issues an acquisition instruction to the main three-phase PLC through a remote communication protocol;
6. the master three-phase PLC judges whether to forward an acquisition instruction to the slave concentrator or not according to the self networking result and the networking result fed back by the slave concentrator;
7. the main concentrator translates the ammeter belonging to the main concentrator into 645 messages and sends the 645 messages to the main ammeter for collecting ammeter data;
8. after receiving the acquisition instruction from the concentrator, translating 645 messages and sending the messages to the electric meter for data acquisition;
it should be noted that the master and slave concentrators cannot simultaneously issue 645 messages, and need to perform time-sharing operation to avoid mutual co-frequency interference.
9. The slave concentrator uploads the acquired data to the main concentrator, and the main concentrator temporarily stores the data;
10. the main concentrator temporarily stores the ammeter data of the main ammeter to which the main concentrator belongs;
11. and uploading all the electric meter data acquired by the master concentrator and the slave concentrator to the metering master station by the master concentrator according to a meter reading instruction issued by the metering master station.
Through the flow, the metering master station realizes transparent and non-perception on the data acquisition of the transformer area, and can avoid the complexity of management and operation and maintenance caused by load adjustment.
Although the PLC is taken as an example for description, if there are field buses of different systems and mixed types such as RS485, CAN, and ethernet, interconnection and intercommunication of different communication modules and collection of electric meter data CAN be realized based on the technical idea of the embodiment of the present invention.
