Description

Technical Field

[0001] This invention relates to a method and system for implementing "install-and-collect" electricity information collection, belonging to the fields of power automation and Internet of Things technology. Background Technology

[0002] With the deepening of smart grid construction, the requirements for the real-time performance and integrity of electricity information collection systems are becoming increasingly stringent. Currently, in electricity marketing operations, there is a significant lag in the process of installing or replacing metering devices (including smart meters, rail meters, smart metering switches, distributed power supply access units, and collection terminals such as concentrators and collectors).

[0003] In the existing business process, after on-site installation is completed, a filing process must first be completed in the marketing business system, and then the file information is pushed to the electricity consumption information collection system. Only after the collection system receives the file can it issue the collection point parameters and collection tasks, and finally conduct data retrieval.

[0004] However, in practice, it has been found that changes to metering devices often involve multi-system, multi-process approvals, and the process from on-site installation to final system archiving can take a considerable amount of time. This disconnect in the process leads to a separation between "installation" and "metering," specifically presenting the following technical problems:

[0005] Data collection lag: Due to delays in system documentation and parameter distribution, newly installed equipment may be physically installed and powered on, but it remains "unregistered" in the system and cannot collect data in a timely manner.

[0006] Impact on critical business operations: This data lag directly affects the normal billing and settlement of market customers, the accurate calculation of line loss, and other critical business operations.

[0007] Manual debugging is cumbersome: Traditional processes often require manual intervention to issue parameters and debug, which is inefficient and cannot meet the needs of rapid deployment of large-scale equipment.

[0008] Therefore, there is an urgent need for a technical solution that can enable simultaneous equipment installation and data acquisition to solve the above problems. Summary of the Invention

[0009] Based on the problems described in the background, the problem to be solved by the present invention is to provide a method and system for implementing "install-and-collect" electricity information collection, so as to solve the above-mentioned problems.

[0010] To achieve the above objectives, the present invention provides the following technical solution: a method for implementing "install-and-collect" electricity information collection in a system, comprising the following steps:

[0011] S1. On-site personnel will take the metering device out of the warehouse and install and power it on. The metering device includes at least one of the following: electricity meter, data collector, rail meter, smart metering switch, distributed power access unit and concentrator.

[0012] S2. After the metering device is powered on, it automatically connects to the communication network through the built-in STA module or its own communication function, and actively reports key information including the device's communication address and protocol type to the concentrator.

[0013] S3. The concentrator receives the reported information, compares it with the local records, and if it is identified as a newly added device, it generates an unknown energy meter event and reports it to the main station of the data acquisition system.

[0014] S4. The main station of the data acquisition system receives events from unknown devices, verifies asset information with the marketing system or industrial control platform, creates temporary files, generates meter reading parameters and sends them to the concentrator, and initiates a remote automatic debugging process.

[0015] S5. After a successful test, the data acquisition system will send the debugging results back to the on-site operation terminal and update the temporary file to the official file after the marketing business is archived.

[0016] Preferably, the processing flow of the concentrator in step S2 is as follows:

[0017] The concentrator CCO has the whitelist disabled by default at the factory. After powering on, it waits for the STA to join the network.

[0018] When the concentrator receives device information reported by the STA or the collector, it periodically reads the device information in the CCO and compares it with the local collection file.

[0019] If the comparison result indicates a new device, an unknown energy meter event is generated and reported to the main station of the data acquisition system via the uplink channel.

[0020] Preferably, the processing flow of the electricity meter in steps S1-S2 is as follows:

[0021] After the electricity meter is powered on, the STA module obtains the electricity meter address as the communication address and sends a network access application to the CCO.

[0022] After a STA successfully joins the network, it obtains device information from the electricity meter. The device information includes at least the communication address and communication protocol type, and actively reports it to the concentrator.

[0023] Preferably, the processing flow of the data collector in steps S1-S2 is as follows:

[0024] After the data collector is powered on, it automatically starts the meter search function and generates a list of device information including the communication address of the connected energy meter, the STA communication address, and the protocol type.

[0025] The collector uses an address-based mode and sends a network access request to the CCO using its own address;

[0026] After successful network access, the device information list is proactively reported to the concentrator via unicast.

[0027] Preferably, the processing flow of the guide rail table in steps S1-S2 is as follows:

[0028] After the rail meter is installed and powered on, it automatically searches the meter via the RS485 interface to generate a list of device information containing the communication addresses and protocol types of itself and its connected devices.

[0029] The STA module obtains the guide rail table address and sends a network access application to the CCO;

[0030] After a STA successfully joins the network, it retrieves the device information list from the guide table and actively reports it to the concentrator.

[0031] Preferably, the processing flow of the intelligent measurement switch in steps S1-S2 is as follows:

[0032] After the smart metering switch is powered on, it searches for meters via RS485 and generates a list of devices containing information about the connected energy meters.

[0033] The STA module obtains the address of the smart measurement switch and connects to the CCO network;

[0034] After successful network access, the device information will be proactively reported to the concentrator.

[0035] Furthermore, the intelligent measurement switch supports data forwarding, forwarding received read or set commands to downstream devices and returning the data to upstream devices.

[0036] Preferably, the processing flow of the distributed power supply access unit in steps S1-S2 is as follows:

[0037] After the distributed power supply access unit is powered on, the STA module obtains the access unit address and sends a network access application to the CCO;

[0038] After the STA successfully joins the network, it obtains device information from the access unit and reports it to the concentrator;

[0039] After receiving the information, the main station of the acquisition system verifies the asset information with the metering intelligent industrial control platform and transmits the voltage data of the downstream photovoltaic inverter to complete the debugging.

[0040] The present invention also provides an "install-and-collect" system for electricity information collection, including a field metering device, a communication network, a concentrator, and a collection system master station;

[0041] The field metering device includes an energy meter, a data collector, a rail meter, a smart measuring switch, and a distributed power supply access unit, which is used to automatically report equipment information after power-on;

[0042] The concentrator is used to receive device information and compare local files. If it is a newly added device, it generates an unknown event report.

[0043] The main station of the data acquisition system includes an automatic filing module and an automatic debugging module;

[0044] The automatic filing module is used to receive unknown device events and create temporary files after verifying them with the external asset system.

[0045] The automatic debugging module is used to generate meter reading parameters and send them to the concentrator, initiate remote time synchronization and data collection, and complete the installation and data collection process immediately.

[0046] Preferably, the main station of the data acquisition system further includes:

[0047] The Unknown Device Temporary Event Cache and Parsing Unit is used to parse the data sent by the concentrator and push it to the specified topic cache.

[0048] The automatic debugging and control unit is used to automatically perform time synchronization, send meter reading parameters and data acquisition schemes after receiving an unknown device event;

[0049] The data migration unit is used to automatically migrate the collected data in the temporary storage table to the official production archive after the marketing system pushes the official archive.

[0050] Preferably, in step S2, the message format for the STA module to report the downstream device information follows the Q / GDW11612,43 protocol amplification, specifically including:

[0051] Function codes: The electricity meter communication module uses function code 2, and the data collector uses function code 3;

[0052] Data subfield: contains the STA reported event type (a value of 50 represents device information), device address, number of downstream energy meters M, and the communication addresses and communication protocol types of the downstream energy meters arranged in sequence.

[0053] The beneficial effects of this invention are:

[0054] 1. This invention utilizes the active reporting function of the communication module (STA), automatically reporting key information upon power-on and network connection. The data collection system can automatically create temporary files and issue collection tasks without waiting for the marketing system to archive them. This achieves "zero-time-difference" connection between physical installation and system data collection, completely eliminating data collection blind spots for newly installed equipment.

[0055] 2. This invention automates the entire process from equipment information reporting, unknown event triggering, automatic file creation, parameter distribution to remote time synchronization and data retrieval. On-site personnel only need to install the equipment; the system automatically completes the debugging process in the background, greatly reducing labor costs and significantly improving the efficiency of installation and debugging.

[0056] 3. Through "install and collect immediately", newly installed equipment can immediately participate in line loss calculation and power freezing, ensuring that market customers can make accurate electricity bill settlements from the start of electricity use, which effectively guarantees the continuity and accuracy of electricity marketing business.

[0057] 4. This invention features a unified technical architecture that is compatible with various devices such as electricity meters, data collectors, DIN rail meters, smart measurement switches, and distributed power access units. Whether it's self-managed metering equipment or marketing participation management equipment, it can achieve immediate data collection through standardized message formats (such as the Q / GDW 11612.43 extended protocol), exhibiting wide applicability and good scalability.

[0058] 5. This invention incorporates a conversion mechanism between "temporary archives" and "official archives." After the marketing system completes its final archiving, the system automatically migrates the temporarily collected data to the official archives, ensuring the integrity and continuity of historical data without requiring manual data entry.

[0066] The embodiments of the present invention will be further described below with reference to the accompanying drawings:

[0067] Example 1

[0068] like Figure 1 As shown, the present invention provides a "install-and-collect" method for an electricity information collection system, comprising the following steps:

[0069] S1. On-site personnel will take the metering device out of the warehouse and install and power it on. The metering device includes at least one of the following: electricity meter, data collector, rail meter, smart metering switch, distributed power access unit and concentrator.

[0070] S2. After the metering device is powered on, it automatically connects to the communication network through the built-in STA module or its own communication function, and actively reports key information including the device's communication address and protocol type to the concentrator.

[0071] The STA module of the rail gauge, intelligent measurement switch, and distributed power access unit needs to support the function of periodically reading the information of the connected devices.

[0072] The STA module of all devices needs to support reporting information about connected devices.

[0073] S3. The concentrator receives the reported information, compares it with the local records, and if it is identified as a newly added device, it generates an unknown energy meter event and reports it to the main station of the data acquisition system.

[0074] S4. The main station of the data acquisition system receives events from unknown devices, verifies asset information with the marketing system or industrial control platform, creates temporary files, generates meter reading parameters and sends them to the concentrator, and initiates a remote automatic debugging process.

[0075] S5. After a successful test, the data acquisition system will send the debugging results back to the on-site operation terminal and update the temporary file to the official file after the marketing business is archived.

[0076] This invention transforms the traditional serial mode of "first create a file, then install, then debug" into a parallel mode of "first install, then trigger, then create a file," decoupling the strong dependency between physical installation and system processes, achieving real-time synchronization, applicable to all types of metering equipment, and providing a general framework for subsequent specific equipment implementation.

[0077] like Figure 7 As shown, the processing flow of the concentrator in step S2 is as follows:

[0078] The concentrator CCO has the whitelist disabled by default at the factory. After powering on, it waits for the STA to join the network.

[0079] When the concentrator receives device information reported by the STA or the collector, it periodically reads the device information in the CCO and compares it with the local collection file.

[0080] If the comparison result indicates a new device, an unknown energy meter event is generated and reported to the main station of the data acquisition system via the uplink channel;

[0081] After a STA successfully joins the network, it proactively reports device information (device communication address, device communication protocol type, STA communication address).

[0082] After receiving the reported device information, the concentrator generates an unknown energy meter event and reports it to the data acquisition system;

[0083] After receiving an unknown new device event reported by the concentrator, the data acquisition system checks it against the electricity meter asset file in the marketing system.

[0084] The data acquisition system establishes formal files for electricity meters, stores the connection relationship between concentrators and electricity meters, and notifies the front-end to update the cache; the data acquisition system generates and distributes meter reading parameters.

[0085] The marketing system pushes complete information on distribution areas and terminals to the electricity information collection system through processes such as business expansion and terminal replacement. The collection system then updates the self-built temporary files of concentrators into formal files.

[0086] The CCO needs to support reporting device information reported by the STA / collector to the concentrator.

[0087] The concentrator needs to support periodic reading of device information within the CCO and comparing it with the data collected within the concentrator to generate unknown energy meter events, preventing omissions.

[0088] The concentrator's processing flow ensures that new devices are not rejected by the network by disabling the whitelist and using a timed comparison mechanism. It can also detect incremental changes in a timely manner. Furthermore, the timed reading and comparison design prevents devices from being missed due to single reporting failures caused by network fluctuations. It has a packet loss prevention mechanism and performs preliminary screening on the concentrator side, reducing the transmission of invalid data to the main station and lowering the processing pressure on the main station.

[0089] like Figure 2 As shown, the specific processing flow of the electricity meter is as follows:

[0090] After the electricity meter is powered on, the STA module obtains the electricity meter address as the communication address and sends a network access application to the CCO.

[0091] After the STA successfully joins the network, it obtains device information from the electricity meter. The device information includes at least the communication address and communication protocol type, and actively reports it to the concentrator.

[0092] The concentrator receives the reported device information and compares it with the files in the concentrator. If it is a newly added device, an unknown energy meter event is generated and reported to the data acquisition system.

[0093] After receiving an unknown electricity meter event reported by the concentrator, the collection system checks it against the electricity meter asset file in the marketing system and obtains the asset information.

[0094] The data acquisition system creates its own temporary files to store the connection relationship between the concentrator and the electricity meter, and notifies the front-end to update the cache; the data acquisition system generates and distributes meter reading parameters, initiates the debugging process, and synchronizes the time with the electricity meter. After successful time synchronization, the data acquisition system feeds back the debugging results to the mobile phone case and the marketing system.

[0095] The marketing system pushes complete user and electricity meter information to the electricity information collection system through processes such as business expansion and meter replacement. The collection system then updates its self-built temporary files into official files.

[0096] The data acquisition system can utilize physical topology identification technology and HPLC identification technology to adjust the IoT relationship between devices.

[0097] As the most basic plug-and-play unit, the electricity meter adopts the active reporting capability of the HPLC communication module, which automatically obtains the meter address without the need for manual entry or infrared reading by on-site personnel, thus avoiding human input errors. At the same time, it uses power line communication, which is plug-and-play and greatly shortens the installation time of a single meter.

[0098] like Figure 3 As shown, the processing flow of the collector is as follows:

[0099] After the data collector is powered on, it automatically starts the meter search function and generates a list of device information including the communication address of the connected energy meter, the STA communication address, and the protocol type.

[0100] The collector uses an address-based mode and sends a network access request to the CCO using its own address;

[0101] After successful network access, the device information list is proactively reported to the concentrator via unicast.

[0102] After receiving the reported device information, the concentrator compares it with the files in the concentrator. If it is a newly added device, an unknown energy meter discovery event is generated and reported to the data acquisition system.

[0103] After receiving a report from the concentrator about the discovery of an unknown electricity meter, the data acquisition system checks it against the electricity meter asset file in the marketing system.

[0104] The data acquisition system creates its own temporary files to store the connection relationship between the concentrator and the electricity meter, and notifies the front-end to update the cache; the data acquisition system generates and distributes meter reading parameters, initiates the debugging process, and synchronizes the time with the electricity meter. After successful time synchronization, the data acquisition system feeds back the debugging results to the mobile phone case and the marketing system.

[0105] The marketing system pushes complete user and electricity meter information to the data collection system through processes such as business expansion and meter replacement. The data collection system then updates its self-built temporary files into official files.

[0106] The data acquisition system can utilize physical topology identification technology and HPLC identification technology to adjust the IoT relationship between devices.

[0107] The collector needs to support actively reporting the table search information to the CCO via unicast until it receives confirmation from the CCO or reaches the maximum number of transmissions.

[0108] The data collector needs to support periodic table searches and compare them with the current table search information. When the information of the downstream devices changes, the data search information is actively reported to the CCO using unicast until the CCO confirms the information or the maximum number of transmissions is reached.

[0109] In normal use, the scenarios of data collectors are complex and involve cascaded devices. The unicast method and change triggering mechanism used in this application ensure the real-time nature of the data. Unicast reporting is a one-to-one reporting method, which is more reliable than the traditional one-to-many broadcast reporting and ensures that the data is delivered. In addition, the change triggering mechanism compares the data periodically, so that new meters in the distribution area can be automatically detected without reconfiguring the data collector.

[0110] like Figure 4 As shown, the specific processing flow of the guide rail table is as follows:

[0111] After the rail meter is installed and powered on, it automatically searches the meter via the RS485 interface to generate a list of device information containing the communication addresses and protocol types of itself and its connected devices.

[0112] The STA module obtains the guide rail table address and sends a network access application to the CCO;

[0113] After a STA successfully joins the network, it retrieves the device information list from the guide table and actively reports it to the concentrator;

[0114] When the concentrator receives the reported device information, it compares the data with the records. If it is a newly added device, it generates an "unknown energy meter discovered" event and reports it to the data acquisition system.

[0115] After receiving a report from the concentrator about the discovery of an unknown energy meter, the data acquisition system checks the asset files of the rail-mounted meter and its associated DC meter in the smart metering control platform to obtain asset information.

[0116] The data acquisition system creates its own archives, storing the connection relationships between the concentrator, the rail meter, and its associated energy meters, and notifies the front-end to update the cache. The data acquisition system generates and distributes meter reading parameters, initiates the debugging process, and calibrates the time of the rail meter and its associated energy meters. After successful calibration, the data acquisition system sends the debugging results back to the phone case.

[0117] The data acquisition system can utilize physical topology identification technology and HPLC identification technology to adjust the IoT relationship between devices.

[0118] The guide rail meter should have a 485 channel automatic meter search function, automatically searching for information on the connected devices upon power-on. The device information list includes the guide rail meter itself and the connected devices.

[0119] Rail-mounted meters typically function as data acquisition nodes, managing multiple sub-devices. However, this invention enables a single "parent node" to bring its "child nodes" into the network, establishing a complete physical topology with a single installation. This solves the problem of maintaining the relationships between rail-mounted meters and their associated meters.

[0120] like Figure 5 As shown, the processing flow of the intelligent measurement switch is as follows:

[0121] After the smart metering switch is powered on, it searches for meters via RS485 and generates a list of devices containing information about the connected energy meters.

[0122] The STA module obtains the address of the smart measurement switch and connects to the CCO network;

[0123] After successful network access, the device information will be proactively reported to the concentrator.

[0124] The concentrator receives the reported device information, compares it with the records, and if it is a newly added device, it generates an "unknown energy meter discovered" event and reports it to the data acquisition system.

[0125] After receiving a report from the concentrator about the discovery of an unknown electricity meter, the data acquisition system checks the electricity meter asset file in the marketing system and the smart metering switch asset file in the smart metering control platform to obtain asset information.

[0126] The data acquisition system creates a temporary file to store the connection relationships between the concentrator, smart metering switches, and electricity meters. It also notifies the front-end to update the cache, generates and distributes meter reading parameters, initiates the debugging process, and synchronizes the time with the smart metering switches and electricity meters. After successful synchronization, the data acquisition system feeds back the debugging results to the mobile phone case and the marketing system.

[0127] For smart metering switches connected to electricity meters, the marketing system pushes complete user and electricity meter information to the data acquisition system through business expansion and meter replacement processes. The data acquisition system then updates its self-built temporary files into official files and distributes them to the concentrators.

[0128] The data acquisition system can utilize physical topology identification technology and HPLC identification technology to adjust the IoT relationship between devices.

[0129] Furthermore, the intelligent measurement switch supports data forwarding, forwarding received read or set commands to downstream devices and returning the data to upstream devices.

[0130] The intelligent measurement switch has an RS485 automatic meter search function, which generates downstream device information based on the search results. The device information list includes the intelligent measurement switch itself and the downstream devices. The intelligent measurement switch needs to support actively reporting the downstream device information to the CCO via unicast until it receives confirmation from the CCO or reaches the maximum number of transmissions. The intelligent measurement switch needs to support periodic meter searches and compare them with the current downstream device information. When the downstream device information changes, it should actively report the downstream device information to the CCO via unicast until it receives confirmation from the CCO or reaches the maximum number of transmissions.

[0131] After receiving read, set, or operate commands, the smart metering switch determines whether the communication address in the command belongs to the address of the device connected to the smart metering switch. It then forwards the command to the device connected to the smart metering switch and sends the data returned by the device connected to the smart metering switch to the uplink device.

[0132] In the above, the intelligent measurement switch is not only a data acquisition point but also a communication relay point. It has added "data forwarding" logic, which enables it to communicate on behalf of downstream devices. This solves the problem that downstream devices, such as old protocol meters, may not be able to communicate directly with the concentrator. The switch performs protocol conversion or signal relay.

[0133] like Figure 6 As shown, the processing flow of the distributed power access unit is as follows:

[0134] After the distributed power supply access unit is powered on, the STA module obtains the access unit address and sends a network access application to the CCO;

[0135] After the STA successfully joins the network, it obtains device information from the access unit and reports it to the concentrator;

[0136] The concentrator receives the reported device information and compares it with the files in the concentrator. If it is a newly added device, an unknown energy meter discovery event is generated and reported to the data acquisition system.

[0137] After receiving a report from the concentrator about the discovery of an unknown electricity meter, the data acquisition system checks the asset files of the access unit in the smart metering control platform and obtains the asset information.

[0138] The data acquisition system creates its own archives, stores the connection relationships between concentrators and access units, and notifies the front-end to update the cache; the data acquisition system generates and distributes meter reading parameters, initiates the debugging process, synchronizes the time with the access unit, and after successful time synchronization, transmits the voltage of the connected photovoltaic inverter through the data acquisition system. After successful reading, the data acquisition system feeds back the debugging results to the mobile phone case.

[0139] The data acquisition system can utilize physical topology identification technology and HPLC identification technology to adjust the IoT relationship between devices.

[0140] After receiving the information, the main station of the acquisition system verifies the asset information with the metering intelligent industrial control platform and transmits the voltage data of the downstream photovoltaic inverter to complete the debugging.

[0141] Photovoltaic equipment involves power generation data and usually includes complex equipment such as inverters. This invention specifically adds the call to "inverter voltage" as a sign of successful commissioning. In particular, a commissioning verification logic specifically designed for photovoltaic scenarios is included: inverter voltage, which ensures the accurate access of distributed power source data and meets the requirements for anti-reverse current and settlement.

[0142] The present invention also provides an "install-and-collect" system for electricity information collection, including a field metering device, a communication network, a concentrator, and a collection system master station;

[0143] The field metering device includes an energy meter, a data collector, a rail meter, a smart measuring switch, and a distributed power supply access unit, which is used to automatically report equipment information after power-on;

[0144] The concentrator is used to receive device information and compare local files. If it is a newly added device, it generates an unknown event report.

[0145] The main station of the data acquisition system includes an automatic filing module and an automatic debugging module;

[0146] The automatic filing module is used to receive unknown device events and create temporary files after verifying them with the external asset system.

[0147] The automatic debugging module is used to generate meter reading parameters and send them to the concentrator, initiate remote time synchronization and data collection, and complete the installation and data collection process immediately.

[0148] The aforementioned system is a systematic mapping of the implementation method. Its key component is the "automatic filing module" on the main station side, which is crucial for achieving zero human intervention. Through modular design, the complex "install and collect" function is decoupled into independent modules, facilitating system maintenance and upgrades. This architecture supports concurrent access from multiple zones and devices, making it suitable for large-scale deployment.

[0149] The main station of the data acquisition system also includes:

[0150] The Unknown Device Temporary Event Cache and Parsing Unit is used to parse the data sent by the concentrator and push it to the specified topic cache.

[0151] The automatic debugging and control unit is used to automatically perform time synchronization, send meter reading parameters and data acquisition schemes after receiving an unknown device event;

[0152] The data migration unit is used to automatically migrate the collected data in the temporary storage table to the official production archive after the marketing system pushes the official archive.

[0153] Among them, the data migration function solves the problem of the separation between temporary data and formal business data. Through the data migration mechanism, it ensures that all data from the moment of installation and power-on can be included in the formal settlement system without the need for manual data entry, thus ensuring data integrity.

[0154] In step S2, the message format for the STA module to report the information of the connected devices follows the Q / GDW11612,43 protocol amplification, specifically including:

[0155] Function code: The communication module of the electricity meter uses function code 2. The STA actively reports an event to the CCO- module to trigger it. After the electricity meter is powered on, its built-in STA module obtains the meter address and directly sends the network access application and equipment information to the concentrator. The collector uses function code 3. The STA actively reports an event to the CCO- collector to trigger it. The collector uses its own address to access the network with the concentrator and tells the concentrator the contents of the collector's downstream list through function code 3.

[0156] When the concentrator receives function code 2, it knows that this is a single-point device. It only needs to parse the address of this meter and add it to the file.

[0157] When the concentrator receives function code 3, it knows that this is a topology node and needs to parse the entire list it reported. It needs to not only create a file for the data collector, but also create a file for all the sub-meters in the list at once.

[0158] Data subfield: contains the STA reported event type (a value of 50 represents device information), device address, number of downstream energy meters M, and the communication addresses and communication protocol types of the downstream energy meters arranged in sequence.

[0159] The message format for the STA module to report downstream device information follows the Q / GDW11612,43 protocol, which is extended to become the underlying communication standard for implementing all the above logic. Through the extension protocol, the function code, device information and topology are defined. The unified message format enables devices from different manufacturers to interconnect and ensures the interoperability of the system. It carries its own address and downstream device information in a single report, reducing the number of communications and improving efficiency.
