Description

Technical Field

[0001] This invention relates to the field of power acquisition technology for communication base stations, and particularly to a comprehensive power acquisition and metering system and method for communication base stations. Background Technology

[0002] With the rapid iteration of mobile communication technology, the large-scale deployment of 5G base stations has made the energy consumption of communication base stations increasingly prominent. The power consumption of 5G equipment is approximately three to four times that of 4G, leading to a significant increase in base station electricity consumption. Meanwhile, to reduce infrastructure construction costs and improve resource utilization, multi-operator shared base stations have become the mainstream model in the industry—within the same base station equipment room, China Tower, as the infrastructure provider, shares the same power supply system with communication equipment from multiple operators such as China Mobile, China Telecom, and China Unicom. Under this "one station, multiple users" power consumption pattern, how to fairly and accurately allocate the total electricity cost of the base station to each operator's users has become a core issue that urgently needs to be addressed in base station operation and management. Base station electricity costs not only directly affect the operating costs of each operator but also concern the economic relationship and trust foundation among multiple parties. Therefore, establishing an energy collection and metering system capable of accurately measuring the independent electricity consumption of each operator and achieving fair allocation of electricity costs is of great significance for ensuring the healthy operation of the shared base station model.

[0003] In existing solutions, the DC metering module and the AC metering module are independent of each other, with different devices collecting power consumption data on the DC and AC sides respectively. The actual power consumption of a base station includes both AC and DC loads. Existing solutions can only provide fragmented branch circuit data, making it difficult to form a comprehensive view of the base station's power consumption and hindering the systematic calculation and verification of the base station's total power consumption.

[0004] Current solutions only focus on the electricity metering of each branch line, without setting up an independent total metering node at the main input line of the base station. Since line losses inevitably occur during the transmission of electricity from the mains power supply cabinet to the loads of each branch line via distribution lines, the current solution cannot accurately determine the total input electricity consumed by the base station, nor can it compare and verify the sum of the metering values ​​of each branch line with the total input electricity, resulting in the long-term inability to quantify line losses. When multiple operators share electricity costs, this "invisible loss" can only be handled using crude methods such as fixed percentage deductions or inclusion in the common cost allocation, lacking a scientific and fair quantitative basis.

[0005] DC and AC metering modules typically function as independent data acquisition terminals, lacking data fusion and processing capabilities. Electricity consumption data from each branch line must be uploaded separately to an independent monitoring platform, manually compiled, and then used for offline spreadsheets or manual calculation of electricity costs. This process is multi-step, error-prone, and the asynchronous timestamps of data from different branches can lead to aggregation discrepancies. This makes it difficult to automate the entire process from data acquisition and loss calculation to electricity cost allocation, impacting the timeliness and accuracy of electricity bill settlement.

[0006] Different operators within a base station may simultaneously occupy both AC and DC branches, and the same physical branch may connect to equipment from different operators at different times. In existing solutions, the correspondence between user codes and physical branches is usually fixed through hardware wiring. Changing user configurations requires modifying the physical wiring, lacking flexible software-defined mapping capabilities and making it difficult to adapt to the actual operation and maintenance scenarios where operator equipment within the base station is frequently adjusted. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a comprehensive power acquisition and metering system and method for communication base stations, thereby solving the technical problems mentioned in the background section.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A comprehensive power acquisition and metering system for communication base stations includes the following modules:

[0010] The AC acquisition module is a dedicated acquisition module for AC power supply of base stations. This module supports synchronous acquisition of up to eight three-phase AC circuits. Each three-phase circuit can be switched to three single-phase AC circuits for parallel acquisition, and can support the acquisition of power of up to twenty-four single-phase AC circuits.

[0011] The DC acquisition module is a dedicated acquisition module for DC power supply of the base station, with one A / D converter channel shared by every eight DC circuits;

[0012] The total incoming line metering module represents the total amount of electrical energy actually consumed by the base station from the mains power side, including the overall consumption of all branch loads and line transmission losses. This value serves as the sole benchmark value for the total electrical energy consumption of the entire base station.

[0013] The main control module establishes communication connections with the AC acquisition module, DC acquisition module, and main incoming line metering module via a bus; it provides a human-machine interface consisting of an LCD display and configuration buttons for maintenance personnel to perform user code configuration, allocation rule setting, and historical data query operations.

[0014] In one possible implementation, the metering chip in the AC acquisition module is used to perform analog-to-digital conversion and digital calculation on the analog voltage and current signals of each AC circuit to generate the effective voltage value, effective current value, active power, reactive power and cumulative power of each circuit.

[0015] In one possible implementation, the DC acquisition module contains three sets of the aforementioned circuit modules, which can simultaneously complete the energy metering of up to twenty-four single-phase DC circuits.

[0016] In one possible implementation, the main incoming line metering module is located at the main AC incoming line of the base station, and is physically located upstream of all branch line acquisition modules.

[0017] In one possible implementation, the main control module includes:

[0018] The individual user power consumption statistics unit is used to classify and summarize the received multi-branch power consumption data and match user branches to accurately calculate the total power consumption of each cooperating user's independent load.

[0019] The electricity cost allocation algorithm unit supports custom allocation rules and automatically completes line loss calculation, electricity cost accounting and allocation by household based on the total input electricity provided by the main incoming line metering module, the electricity consumption of each user's independent load and the electricity consumption of public equipment. At the same time, the main control module also has abnormal alarm and status monitoring functions, which can monitor the operating status of each module in the system and abnormal electricity consumption in real time.

[0020] One possible implementation includes the following steps:

[0021] Step S1: The main control module initializes the port, and the operation and maintenance personnel configure the data acquisition mode, bind the user code, and set the allocation period and electricity price, and save the parameters;

[0022] Step S2: The main control module issues a data acquisition command. The AC module and DC module acquire and upload the electrical parameters of each branch, and the main incoming line module acquires and uploads the total input power. The main control module receives and stores the data.

[0023] Step S3: The main control module collects the electricity of each branch to the corresponding user and summarizes it into the electricity consumption of independent loads. The electricity of the shared branch is accumulated separately, and the records are frozen at the end of the settlement period.

[0024] Step S4: The main control module reads the total input, the electricity consumption of each user and the shared electricity consumption, calculates the total loss and allocates it according to the proportion of electricity consumption, generates the final settlement bill and saves and displays it;

[0025] Step S5: The main control module synchronously monitors the communication status, data anomalies, and power balance, issues out-of-tolerance alarms, and writes the data to the storage module for future reference.

[0026] In one possible implementation, in step S1, the main control module automatically completes the initialization of each communication port and the handshake connection with each acquisition module. The operation and maintenance personnel perform the initialization configuration through the human-machine interface of the main control module, including setting the communication acquisition mode, user code configuration and allocation rule setting. After the configuration is completed, the main control module stores all configuration parameters in the internal storage module.

[0027] In one possible implementation, in step S2, the main control module sends data acquisition instructions to the AC acquisition module, DC acquisition module and main incoming line metering module via the bus according to a preset sampling period. Each module generates electrical parameter data according to its own working mode and packages and uploads it to the main control module. The main control module receives all data in real time and stores it in the internal data storage module according to the branch number and timestamp.

[0028] In one possible implementation, in step S3, the main control module parses the physical branch number to which each data packet belongs, and automatically collects the cumulative power consumption data of the branch into the data account of the corresponding user code according to the "physical branch - user code" mapping table established in step S1. When the same user is associated with multiple branches, the data is automatically aggregated to form the user's independent total load power consumption. Branches marked with "shared" user codes are separately accumulated as the total power consumption of public equipment. The data is frozen and stored in the history record at the end of the settlement period.

[0029] In one possible implementation, in step S4, the electricity cost allocation algorithm module built into the main control module reads the total electricity consumption of each user's independent load, the total electricity consumption of public equipment, and the total cumulative input electricity of the base station at the end of the settlement period. It calculates the total transmission loss of the line and equipment and allocates the loss according to the energy consumption ratio weight. That is, each user bears the corresponding loss according to the proportion of its own independent load electricity consumption to the sum of the total independent load electricity consumption of all users. The final settlement electricity for each user is the total independent load electricity consumption plus the loss to be allocated, multiplied by the electricity price to generate an electricity cost settlement list and save it to the storage module and the human-machine interface for display output.

[0030] Beneficial effects compared to existing technologies:

[0031] 1. In this solution, the system's AC acquisition module supports simultaneous acquisition of up to eight three-phase AC circuits, and each three-phase circuit can be independently switched to three single-phase circuits for parallel acquisition, supporting the acquisition of power from up to twenty-four single-phase AC circuits. This flexible configuration allows the same hardware module to adapt to the actual situation of mixed wiring of three-phase and single-phase loads, eliminating the need to configure different acquisition devices for different load types. Simultaneously, the DC acquisition module adopts a rotating acquisition architecture of "eight-channel multiplexers plus one-channel A / D converter," with three groups operating in parallel. This achieves high-density acquisition of up to twenty-four single-phase DC circuits with fewer A / D channel resources, accurately covering the power consumption monitoring of DC loads such as base station DC power supplies and communication main equipment. This design effectively solves the problem of refined branch metering of mixed AC and DC loads in multi-operator co-location scenarios, providing a complete and reliable data foundation for subsequent independent accounting for each household.

[0032] 2. In this solution, a total incoming line metering module is installed at the main AC incoming line of the base station. Physically, this module is upstream of all branch line acquisition modules. The measured total cumulative input power serves as the sole benchmark value for the actual power consumption of the base station from the mains power supply. At the end of the settlement period, the electricity cost allocation algorithm unit built into the main control module accurately calculates line losses by subtracting the sum of individual user load power consumption from the total input power consumption and then subtracting the power consumption of common equipment. Subsequently, the losses are allocated according to the proportion of each user's individual load power consumption to the sum of all users' individual load power consumption, ensuring that loss allocation is linked to the actual power consumption of each user. This avoids the unfair phenomenon of using a fixed percentage deduction or including it in the common allocation due to the inability to quantify line losses. Finally, a settlement list is automatically generated, including individual load power consumption, allocated loss power consumption, settlement power consumption, and the total electricity cost payable. This mechanism solves the long-standing electricity cost disputes caused by the inability to reasonably allocate line losses in multi-operator co-location models, achieving full automation from data acquisition, loss calculation, cost allocation to settlement list generation.

[0033] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0034] Figure 1 This is a schematic diagram of the system framework of the present invention;

[0035] Figure 2 This is a schematic diagram of the method flow of the present invention. Detailed Implementation

[0036] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can also be implemented in various different forms, and therefore the present invention is not limited to the embodiments described below.

[0037] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0038] Example:

[0039] Please refer to Figures 1 to 2 As shown in the figure, this embodiment introduces a comprehensive power acquisition and metering system and method for communication base stations, which are used in conjunction with the system and method.

[0040] The communication base station integrated power acquisition and metering system provided by the present invention includes an AC acquisition module, a DC acquisition module, a main incoming line metering module, and a main control module;

[0041] The AC acquisition module is a dedicated acquisition module for AC power supply of base stations. This module supports simultaneous acquisition of up to eight three-phase AC circuits, and each three-phase circuit can be switched to parallel acquisition of three single-phase AC circuits, that is, it can support the acquisition of power of up to twenty-four single-phase AC circuits. This enables the application scenario of mixed use of three-phase and single-phase branches, and comprehensively covers the branch power metering of all AC loads such as base station air conditioning, lighting, and AC power distribution equipment. The AC acquisition module also integrates a metering chip and an isolation sampling circuit. The metering chip is used to perform analog-to-digital conversion and digital calculation on the analog voltage and current signals of each AC circuit to generate the effective voltage value, effective current value, active power, reactive power and cumulative power of each circuit. The isolation sampling circuit is set between the voltage or current transformer and the metering chip to achieve electrical isolation between the strong side and the weak side, suppress common-mode interference and protect the back-end circuit. At the same time, the module has electromagnetic interference protection capability in its circuit design. Electromagnetic interference filters are set at its power input terminal and signal input terminal to ensure continuous and stable operation of the base station in the complex electromagnetic working environment.

[0042] The DC acquisition module is a dedicated acquisition module for base station DC power supply. Internally, it adopts a circuit structure of multiplexer + A / D converter. Every eight DC loops are connected to the input of a multiplexer, and the output of the multiplexer is connected to the input channel of an A / D converter. That is, every eight DC loops share one A / D converter channel. The DC acquisition module has three sets of the above circuit modules. In each set, the multiplexer performs rapid switching of its eight connected loops under the drive of control logic, and sends the analog signals of each loop to the shared A / D converter for analog-to-digital conversion in sequence. Based on this architecture, the DC acquisition module can simultaneously complete the power metering of up to twenty-four single-phase DC loops, accurately acquiring the power consumption data of DC loads such as base station DC power supply and communication main equipment.

[0043] The main incoming line metering module is located at the main AC incoming line of the base station, i.e., the output side of the base station's mains power supply cabinet. In terms of physical topology, it is located upstream of all branch circuit acquisition modules. That is, the current flows from the mains power supply cabinet through the main incoming line metering module before being distributed to the branch circuits monitored by each AC acquisition module and DC acquisition module. The module integrates a high-precision three-phase metering chip and voltage and current sampling circuits. It collects the voltage and current signals of the base station's main input side in real time through voltage transformers and current transformers. The metering chip calculates the base station's total active power, total reactive power, and total cumulative input power. The total cumulative input power represents the total amount of electrical energy actually consumed by the base station from the mains power side, including the overall consumption of all branch loads and line transmission losses. This value serves as the sole benchmark value for the total electrical energy consumption of the entire base station. In the subsequent electricity cost allocation algorithm, the sum of the metering values ​​of each branch is subtracted from this benchmark value to obtain the loss amount when calculating the line loss, thereby realizing the quantitative calculation and fair allocation of losses.

[0044] The main control module is the control and data processing part. It establishes communication connections with the AC acquisition module, DC acquisition module and main incoming line metering module through the bus. It has multiple built-in bus interfaces for sending acquisition commands to each acquisition module and receiving the power acquisition data of all AC and DC branches and the total input power data uploaded by each acquisition module in real time. It has built-in Flash memory for long-term retention of power consumption data, alarm logs and settlement history. It provides a human-machine interface consisting of an LCD display and configuration buttons for operation and maintenance personnel to perform operations such as user code configuration, allocation rule setting and historical data query.

[0045] The main control module also integrates a household electricity consumption statistics unit and an electricity cost sharing algorithm unit;

[0046] The individual user power consumption statistics unit is used to classify and summarize the received multi-branch power consumption data and match user branches to accurately calculate the total power consumption of each cooperating user's independent load.

[0047] The electricity cost allocation algorithm unit supports custom allocation rules and automatically completes line loss calculation, electricity cost accounting and allocation by household based on the total input electricity provided by the main incoming line metering module, the electricity consumption of each user's independent load and the electricity consumption of public equipment. At the same time, the main control module also has abnormal alarm and status monitoring functions, which can monitor the operating status of each module in the system and abnormal electricity consumption in real time.

[0048] The integrated power acquisition and metering method for communication base stations provided by this invention will be described in detail below, taking into account the functional modules of the aforementioned system. This method corresponds to the specific processing procedures executed by each module in the aforementioned system during operation, and the specific steps are as follows:

[0049] Step S1: The main control module initializes the port, and the operation and maintenance personnel configure the data acquisition mode, bind the user code, and set the allocation period and electricity price. The parameters are then saved.

[0050] After the system powers on, the main control module automatically initializes each communication port and establishes handshake connections with each acquisition module. Maintenance personnel perform initialization configuration through the main control module's human-machine interface, including setting the AC acquisition mode. Based on the base station's AC power supply circuit layout, the acquisition mode for each three-phase circuit is set via the corresponding physical configuration buttons for each AC circuit or remotely through the main control module's human-machine interface. Circuits connecting to three-phase AC loads such as air conditioners and three-phase power distribution equipment are set to "three-phase acquisition mode," while circuits connecting to single-phase AC loads such as lighting equipment are set to "single-phase acquisition mode." At this time, the three phases... The circuit is split into three independent single-phase acquisition channels; the user code configuration binds each physical branch, including AC and DC branches, to the operator's user code one by one. Each branch load interface can be used to connect to the load of any operator. The configuration method is completely software-defined and does not require modification of the physical wiring. For the branches corresponding to the common equipment in the base station, the user code is set as the common area identifier, and the allocation rules are set through the human-machine interface to set the allocation period, such as the natural month, the electricity price, and the basic information of each user. After the configuration is completed, the main control module stores all configuration parameters in the internal storage module.

[0051] Step S2: The main control module issues a data acquisition command. The AC module and DC module acquire and upload the electrical parameters of each branch, and the main incoming line module acquires and uploads the total input power. The main control module receives and stores the data.

[0052] The main control module sends data acquisition commands to the AC acquisition module, DC acquisition module, and main incoming line metering module via the bus according to a preset sampling period. Upon receiving the acquisition command, the AC acquisition module acquires the voltage and current signals of each AC circuit using a high-precision metering chip and isolated sampling circuit, based on the preset acquisition mode of each circuit. It then calculates and generates the effective voltage value, effective current value, active power, reactive power, and cumulative energy for each circuit in real time. The cumulative energy is calculated based on the integral of active power over time and continuously accumulated and stored in the register inside the metering chip. The AC acquisition module packages the acquired data from each circuit and uploads it to the main control module via the bus. Upon receiving the acquisition command, the DC acquisition module's three sets of "eight-channel multiplexer + one-channel A / D converter" circuit modules work in parallel. Each set of multiplexers selects the DC signal at preset time intervals. The eight connected DC circuits are rapidly switched in turn, sending the analog signals of each circuit to a shared A / D converter for analog-to-digital conversion. The A / D converter converts the analog voltage / current signals input from each circuit into digital quantities, which are then transmitted to the microprocessor inside the DC acquisition module. The microprocessor calculates the real-time voltage and current of each DC circuit and accumulates the cumulative power of each DC circuit using the ampere-hour integration method. The DC acquisition module packages and uploads the acquired data to the main control module. After receiving the acquisition command, the main input metering module uses its high-precision three-phase metering chip to collect the voltage and current signals of the base station's main input side in real time, generating the total input active power and the total cumulative input power, and packages and uploads the data to the main control module. The main control module receives the data uploaded by all the above acquisition modules in real time and stores it in its internal data storage module according to branch number and timestamp.

[0053] Step S3: The main control module collects the electricity consumption of each branch to the corresponding user and summarizes it as the electricity consumption of an independent load. The electricity consumption of the shared branch is accumulated separately, and the records are frozen at the end of the settlement period.

[0054] During periodic data collection, the main control module automatically performs household power consumption statistics: it parses the physical branch number to which each data packet belongs, looks up the user code corresponding to the physical branch according to the physical branch and user code mapping table established in step S1, and automatically collects the cumulative power consumption data of the branch into the data account corresponding to the user code; for cases where the same user is associated with multiple branches, such as an operator occupying both DC Line 1 and AC Line 3 at the same time, the main control module automatically summarizes and adds up the power consumption data of all associated branches of the user to form the user's independent total load power consumption; for branches marked as shared by user codes, the main control module separately adds up their power consumption to the total power consumption of shared equipment; the above statistical process is performed in real time, and at the end of each settlement period, the main control module freezes and stores the summarized power consumption data of each user and the total power consumption data of shared equipment in the historical record.

[0055] Step S4: The main control module reads the total input, the electricity consumption of each user and the shared electricity consumption, calculates the total loss and allocates it according to the proportion of electricity consumption, generates the final settlement bill and saves and displays it.

[0056] The main control module's built-in electricity cost allocation algorithm automatically executes the following allocation and settlement process at the end of the settlement period: It reads the total electricity consumption of each user's independent load, the total electricity consumption of public equipment, and the total cumulative input electricity of the base station provided by the total incoming line metering module within the current settlement period; it calculates the total transmission loss of the lines and equipment, which equals the total input electricity minus the sum of the electricity consumption of each user's independent load, and then minus the total electricity consumption of public equipment. This loss includes line copper losses, transformer iron losses, and other energy consumption in the transmission process; the main control module calls the custom allocation rules pre-set by the maintenance personnel, i.e., allocation according to energy consumption ratio weights, with each user bearing the corresponding line loss according to the proportion of their own independent load electricity consumption to the sum of the total independent load electricity consumption of all users. The system calculates the electricity loss to be shared by a user, which is equal to the total loss multiplied by the user's total independent load electricity consumption divided by the sum of the total independent load electricity consumption of all users. Then, it calculates the final settlement electricity consumption for each user, which is equal to the user's total independent load electricity consumption plus the user's share of the loss electricity consumption. The system automatically generates an electricity bill settlement list for each user by multiplying the final settlement electricity consumption of each user by the preset electricity price. The list includes the user name, independent load electricity consumption, shared loss electricity consumption, final settlement electricity consumption, and total electricity bill payable. Finally, the settlement list is saved to the storage module and displayed through the human-computer interaction interface. Through the above steps, the system completes the entire process of automation from data collection, loss calculation, electricity bill allocation to bill output.

[0057] Step S5: The main control module synchronously monitors the communication status, data anomalies, and power balance, issues out-of-tolerance alarms, and writes the data to the storage module for future reference.

[0058] During system operation, the main control module synchronously performs status monitoring and anomaly alarm functions, including equipment communication status monitoring. It periodically sends heartbeat detection commands to the AC acquisition module, DC acquisition module, and main incoming line metering module. If no response is received from a certain acquisition module within a preset timeout period, the device is deemed to have a communication anomaly, and an alarm message is immediately displayed through the human-machine interface. For power consumption anomaly monitoring, it dynamically monitors the real-time power and cumulative power consumption of each branch. When a sudden power surge exceeding a preset threshold, an abnormal jump in cumulative power consumption, or a low power factor is detected in a branch, the anomaly event is automatically recorded. The alarm information, including the occurrence time, branch number, and anomaly type, is displayed through a human-machine interface. The power balance verification periodically checks whether the sum of each user's power consumption, the power consumption of public equipment, and losses is approximately equal to the total input power. When the deviation exceeds a preset reasonable range, such as ±3%, it is determined that there is a metering anomaly, line anomaly, or suspected electricity theft. The system automatically records and alarms to prompt maintenance personnel to investigate promptly. Long-term data retention involves writing all power consumption data, alarm logs, and settlement records from each branch into the data storage module to achieve long-term retention and historical traceability of power consumption data, providing a basis for subsequent audits and dispute investigations.

[0059] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.

The integrated power acquisition and metering system and method for a communication base station as described in claim 6, characterized in that, In step S4, the electricity cost allocation algorithm module built into the main control module reads the total electricity consumption of each user's independent load, the total electricity consumption of public equipment, and the total cumulative input electricity of the base station at the end of the settlement period. It calculates the total transmission loss of the line and equipment and allocates the loss according to the energy consumption ratio weight. That is, each user bears the corresponding loss according to the proportion of its own independent load electricity consumption to the sum of the total independent load electricity consumption of all users. The final settlement electricity for each user is the total independent load electricity consumption plus the loss to be allocated, multiplied by the electricity price to generate an electricity cost settlement list and save it to the storage module and human-machine interface for display output.
