Description

Technical Field

[0001] This utility model relates to the field of concentrator technology, specifically to a concentrator for Bluetooth communication meter reading. Background Technology

[0002] The power industry has widely adopted remote automatic meter reading systems for remotely reading user meters. These systems consist of a concentrator and the meter. The meter transmits the collected data to the concentrator via power line carrier wave. Typically, one concentrator is used per area, and the data is then transmitted to the enterprise data center via 4G. This traditional carrier wave meter reading scheme is limited by power line constraints; the meter reading terminal must be on the same power line as the meter to read data correctly. In some complex or distributed power network environments, meter reading efficiency is low, or even impossible, and the cost is high. Furthermore, in complex and variable power network environments, this traditional carrier wave meter reading scheme suffers from insufficient stability, failing to detect and report faults promptly. When a system malfunctions, it is difficult to quickly locate the problem and perform maintenance, increasing operation and maintenance costs and complexity. Utility Model Content

[0003] To address the problems existing in the background technology, this utility model provides a Bluetooth communication meter reading concentrator, which includes:

[0004] The control unit processes data, performs store-and-forward operations, and coordinates the overall functionality.

[0006] Storage unit, temporarily storing meter data collected via Bluetooth interface;

[0007] The 4G uplink interface enables data communication with the data center via the 4G module, uploading the meter data stored in the storage unit to the data center.

[0008] The energy storage module interface connects to the energy storage module. When the main power supply of the concentrator is abnormal, it provides temporary power to the concentrator and reports the offline information to the data center through the 4G uplink interface.

[0009] The Bluetooth downlink communication interface is equipped with a Bluetooth router board, which searches for and connects to the electricity meter to collect and transmit data.

[0010] The control unit, power adapter unit, storage unit, 4G uplink interface, energy storage module interface and Bluetooth downlink communication interface are all integrated on the same circuit board.

[0013] In a preferred embodiment, the concentrator reads data from the paired smart meter via Bluetooth routing and stores it in the storage unit.

[0014] The beneficial effects achieved by this utility model are as follows:

[0015] This utility model's concentrator is easy to assemble and use.

[0016] Figure 1 This is a structural diagram of a concentrator for Bluetooth communication meter reading. Detailed Implementation

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Reference Figure 1 The Bluetooth communication meter reading concentrator of this utility model mainly consists of the following parts:

[0019] Control Unit: The control unit is the core processing part of the entire concentrator, responsible for data processing, storage and forwarding, and overall functional coordination and control.

[0020] Power adapter unit: The power adapter unit provides a stable power supply to the concentrator to ensure the normal operation of each functional module.

[0021] Storage Unit: The storage unit is used to temporarily store the meter data collected via the Bluetooth interface, so that it can be uploaded to the data center via the 4G module later.

[0022] 4G uplink interface: The 4G uplink interface enables data communication with the data center through the 4G module, uploading the meter data stored in the storage unit to the data center.

[0023] Energy storage module interface: The energy storage module interface is used to connect the energy storage module. When the main power supply of the concentrator fails abnormally, the energy storage module can supply power to the concentrator in a short time to ensure data transmission and reporting.

[0024] Bluetooth downlink communication interface: By plugging into a Bluetooth router board, the Bluetooth downlink communication interface can automatically search for and connect to matching electricity meters with Bluetooth modules within a 200-meter range for data collection and transmission.

[0025] The control unit, power adapter unit, storage unit, Bluetooth downlink communication interface, energy storage module interface, and 4G uplink communication interface of this utility model are all integrated on the same circuit board.

[0026] The control unit is connected to each functional module through pins and circuits on the circuit board to realize data transmission and the issuance of control commands.

[0027] The power adapter unit provides power to the control unit, storage unit, 4G uplink interface, energy storage module interface and Bluetooth downlink communication interface to ensure that they can work properly.

[0028] The storage unit receives meter data transmitted via pins from the Bluetooth downlink communication interface and stores the data for later uploading via the 4G uplink interface.

[0029] The 4G uplink interface is connected to the control unit and is responsible for uploading the meter data stored in the storage unit to the data center.

[0030] The energy storage module interface is connected to the control unit. When the main power supply of the concentrator is abnormal, the energy storage module provides short-term power to the concentrator and reports the offline information to the data center through the 4G uplink interface.

[0031] The Bluetooth downlink communication interface connects wirelessly to the electricity meter carrying a Bluetooth module by plugging into the Bluetooth router board, enabling data collection and transmission. The collected data is then transmitted to the control unit via pins.

[0032] The control unit connects to the Bluetooth router board via the Bluetooth downlink interface, eliminating the need for a power line connection. It can connect to Bluetooth-enabled response meters already installed in the community and collect their data. The collected data is stored in the storage unit and then uploaded to the power company's data center via the 4G uplink interface.

[0033] The working process of a Bluetooth communication meter reading concentrator is as follows:

[0034] Initialization and configuration: After the concentrator is powered on, it first performs initialization configuration, including loading the program in the control unit, configuring network parameters (such as the APN, username and password of the 4G network, etc.), and checking the status of the Bluetooth router and energy storage module.

[0035] Bluetooth Search and Connection: After the Bluetooth downlink communication interface of the concentrator is plugged into the Bluetooth router, the Bluetooth router automatically begins searching for matching electricity meters with Bluetooth modules within a 200-meter radius. Once a connectable meter is found, the Bluetooth router establishes a communication connection with it.

[0036] Data Acquisition: After establishing a connection with the electricity meter, the Bluetooth router sends meter reading commands to the meter according to the predetermined meter reading frequency (e.g., once a day or every two hours). Upon receiving the commands, the meter returns the collected data such as electricity consumption, voltage, and current. The Bluetooth router then transmits this data to the concentrator's control unit via pins.

[0037] Data storage: After receiving the meter data, the control unit first performs data verification and processing to ensure the accuracy and integrity of the data, and then stores the data in the built-in storage unit. The storage unit can be a non-volatile memory such as EEPROM or Flash, ensuring that the data is not lost in the event of a power outage.

[0038] Data Upload: The concentrator uploads meter data from the storage unit to the power company's data center via its built-in 4G uplink interface. This process can be scheduled (e.g., uploaded at a fixed time each day) or performed instantly based on requests from the data center.

[0039] Remote Control and Monitoring: Data centers can remotely control and monitor concentrators. For example, a data center can proactively send a call command to the concentrator, requesting it to immediately collect and upload instantaneous data from one or more meters. Upon receiving the command, the concentrator will immediately execute the corresponding operation and return the collected data to the data center.

[0040] Fault Detection and Reporting: If the concentrator's main power supply experiences an abnormal power outage, the integrated energy storage module will temporarily power the concentrator, ensuring the system can continue operating for a period of time. During this period, the concentrator will report a command to the data center via the 4G uplink interface, informing the data center that the concentrator has gone offline. In this way, R&D and maintenance personnel can quickly locate and handle the problem based on the reported information.

[0041] Cyclic Execution: The above process is a cyclical execution process. The concentrator will continuously perform operations such as Bluetooth searching, data collection, data storage, and data uploading to ensure that power companies can obtain the electricity consumption data of each meter in real time.

[0042] Example 1: In this example, data from the paired smart meters is read once a day or every two hours via Bluetooth router and then stored in the storage unit. From the data center, the usage of concentrators and meters in each distribution area can be monitored. The data center can also actively send call commands to the concentrator devices to collect the electricity meter data stored in the concentrators.

[0043] Example 2: In this example, the data center directly sends a call to the concentrator to collect a certain instantaneous data from the electricity meter. After receiving the command from the data center, the concentrator transmits the information to the Bluetooth router board through a pin. The Bluetooth router board collects the data from the smart meter and returns the collection result to the concentrator through a pin. The concentrator then returns the data to the data center through the 4G uplink communication module. This process generally only takes about 10 seconds, and the instantaneity is very high.

[0044] Example 3: In this example, technicians monitor the usage of concentrators in each distribution area from the data center. If a concentrator is found to be unable to collect meter data normally, they promptly check the messages reported by the concentrator through the 4G uplink module to make a preliminary judgment. When the remote meter reading concentrator experiences an unexpected power outage, the energy storage module on the concentrator will briefly supply power to the concentrator. The concentrator will detect this power outage event and transmit the information to the 4G uplink communication module via its pins, which then transmits it to the data center. This allows R&D personnel to make a preliminary judgment on the concentrator that is not collecting meter data normally, to see if insufficient power supply to the concentrator is causing the inability to collect meter data normally.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
