Description

Technical Field

[0001] The present invention relates to the technical field of power grid monitoring, and in particular to a method, a terminal and a storage medium for collecting transformer monitoring data. Background Art

[0002] With the expansion of electricity consumption information collection services, the dedicated transformer collection terminals in the electricity consumption information collection system support more services, among which the online transformer error monitoring service has been widely used. In this service, the end cap and the transformer are connected through hardware to collect the transformer's voltage and current.

[0003] The existing power grid monitoring method is to send collection plans, collection tasks, and collection files to the dedicated transformer collection terminal through the master station. The parameters sent include various data items to be read, reading time, reading frequency, collection type, storage time stamp, user type and other parameters, and these parameters are used to classify tasks. The dedicated transformer collection terminal saves the parameters sent by the master station, classifies and stores them according to the parameters, and inserts tasks for reading.

[0004] However, the existing technology is mainly aimed at devices with asset numbers such as electricity meters, while the collection end cover as a sub-device does not have an asset number and cannot be sent to the dedicated transformer collection terminal through the main station; the terminal can only read the meter after the parameters are sent by the main station, and the collection plan, collection task, and collection file must be sent at the same time. The parameters involved are numerous and complex, and are mainly suitable for meter reading in the electricity information collection system. The end cover device only has two data items, voltage and current, and the collection type only has real-time data. The reading time and frequency need to be determined according to the charge and discharge status of the end cover. Therefore, most of the parameters sent are not used, the operation is inconvenient and prone to errors; in addition, the dedicated transformer collection terminal has 3 Bluetooth channels and can connect to 3 Bluetooth sub-devices at the same time, but the existing technology can only use one channel for connection and cannot connect to multiple devices at the same time. When it is necessary to communicate with multiple sub-devices, it is necessary to constantly establish connections with the sub-devices, transmit data, and disconnect, and the task execution efficiency is low.

[0049] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0051] Figure 1 The flowchart is a schematic diagram of a method according to an embodiment of the present invention. According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted.

[0052] like Figure 1 As shown, the method includes:

[0053] Step 110, generating a Bluetooth name for the end cap based on the phase of the line detected by the end cap, wherein the end cap is used to collect transformer monitoring data;

[0054] Step 120: Send a Bluetooth broadcast and obtain response data of the end cover to the Bluetooth broadcast, wherein the response data includes a Bluetooth name and a Bluetooth MAC address;

[0055] Step 130: Send a request for establishing Bluetooth communication to the end cover based on the response data, and establish a Bluetooth channel between the idle Bluetooth device of the dedicated transformer acquisition terminal and the end cover;

[0056] Step 140: Acquire the transformer monitoring data collected by the end cap through the Bluetooth channel.

[0057] To facilitate understanding of the present invention, the transformer monitoring data acquisition method provided by the present invention is further described below based on the principle of the transformer monitoring data acquisition method of the present invention and in combination with the process of acquiring transformer monitoring data in the embodiment.

[0058] At the equipment installation site, each substation corresponds to an electrical box, which houses a dedicated transformer data collection terminal and three data collection end caps. The dedicated transformer data collection terminal has three Bluetooth sub-device channels. The end caps have unique MAC addresses, and their Bluetooth names are distinguished by phases A, B, and C. By matching the end caps for phases A, B, and C to the three Bluetooth channels of the dedicated transformer data collection terminal, all three end caps can be read online simultaneously, eliminating the need for repeated connection, communication, and disconnection, thus improving communication efficiency.

[0059] During a Bluetooth connection, the dedicated transformer acquisition terminal acts as the master device, and the three end caps act as Bluetooth sub-devices. The dedicated transformer acquisition terminal receives the end cap's Bluetooth broadcast and obtains its Bluetooth name and Bluetooth MAC address from the broadcast. It then determines whether it is an end cap device by judging the Bluetooth name. If it is an end cap device, it determines the ABC phases. The dedicated transformer acquisition terminal stores the corresponding Bluetooth MAC address in ABC order and connects using three Bluetooth channels based on the MAC addresses, thus achieving automatic connection between the dedicated transformer acquisition terminal and the end caps. This solves the problem of Bluetooth sub-devices being unable to download parameters from the master station without asset numbers, or complex parameters being inapplicable.

[0060] In general, due to the short Bluetooth transmission distance and the long distance between electrical boxes, the dedicated transformer acquisition terminal can only connect to the corresponding three end covers when automatically connected. However, there are also cases where the distance between two electrical boxes is close. If automatic connection is used, the dedicated transformer acquisition terminal of one electrical box will be connected to the acquisition end cover of another electrical box. In order to solve this problem, the present invention implements a method of manually setting the MAC address for connection. The MAC address is unique. When the MAC addresses of the corresponding three end covers are entered in sequence on the screen of the dedicated transformer acquisition terminal, the dedicated transformer acquisition terminal will store the address and only connect according to the set address. This avoids the problem of cross-connection between the transformer acquisition terminal in one area and the end covers of other areas.

[0061] The user does not need to set the manual mode and automatic mode. The dedicated acquisition terminal will automatically determine whether the address is stored. If the address is not stored, the read address is 0, then the connection will be made automatically. If the read address is not 0, then the connection will be made according to the read address. Figure 2 shown.

[0062] Specifically, the execution device of the transformer monitoring data collection method is a dedicated transformer collection terminal, and the method includes the following steps:

[0063] S1. Generate a Bluetooth name for an end cap based on a phase of a line detected by an end cap, where the end cap is used to collect transformer monitoring data.

[0064] A number is generated in advance for the electrical box in each substation. The electrical box is equipped with a special transformer collection terminal and three end covers. The three end covers respectively collect voltage and current data of the three-phase line of the transformer; the phase corresponding to the end cover is obtained, and the number and the phase are combined into the Bluetooth name of the end cover.

[0065] In the management of power substations, to improve the efficiency and accuracy of data collection, we pre-generate unique numbers for each substation's electrical box. This number is usually automatically generated based on certain naming rules and existing substation information in the system, ensuring that each substation has a clear and identifiable identity.

[0066] Before a switch box is put into use, the end caps require secondary configuration. First, use a dedicated transformer acquisition terminal or a specialized configuration tool to obtain the phase corresponding to each end cap (i.e., phase A, phase B, or phase C). This phase information is then combined with the switch box number to generate a new Bluetooth name. This new Bluetooth name incorporates both the switch box number and the phase to which the end cap is connected, significantly improving end cap management efficiency.

[0067] In this way, we can not only conveniently remotely identify and manage each end cap, but also quickly locate the specific electrical box and phase based on the Bluetooth name, which greatly facilitates troubleshooting and data analysis of the power system.

[0068] S2. Receive a configuration file sent by the upper terminal, which includes the activation of the monitoring transformer function as a trigger condition for establishing Bluetooth communication between the dedicated transformer acquisition terminal and the end cover, and the Bluetooth name format of the end cover; load the configuration file, and send a Bluetooth broadcast when the monitoring transformer function is activated.

[0069] S3. When the mutual inductor monitoring function is enabled, a Bluetooth broadcast is sent, and response data of the end cover to the Bluetooth broadcast is obtained, where the response data includes a Bluetooth name and a Bluetooth MAC address.

[0070] Retrieve a device list and read the status of each Bluetooth device from the device list; select a Bluetooth device that is not connected as an idle Bluetooth device; and control the idle Bluetooth device to broadcast the Bluetooth name and Bluetooth MAC address of the idle Bluetooth device.

[0071] First, retrieve the device list through a specific system interface. This device list contains the identification information of all Bluetooth devices, such as Bluetooth name, model, connection status, etc. The purpose of this step is to have a comprehensive understanding of the Bluetooth devices in the system.

[0072] Next, read the status of each Bluetooth device from the device list. Bluetooth device states typically include connected, unconnected, pairing, disconnected, etc. By reading the device status information, you can determine which devices are currently active and which are idle.

[0073] After reading the status of all Bluetooth devices, filter them based on their status information. Specifically, select those Bluetooth devices with a status of "unconnected" as idle Bluetooth devices. These idle Bluetooth devices are ready to connect and operate at any time and are in a standby state in the system.

[0074] Finally, for each idle Bluetooth device selected, we need to use control commands to broadcast its Bluetooth name and Bluetooth MAC address. The Bluetooth name is a unique identifier for a Bluetooth device, used to distinguish different Bluetooth devices; the Bluetooth MAC address is the physical address of the Bluetooth device, used to locate the device on the Bluetooth network. By broadcasting these two pieces of information, other devices or systems are aware of the idle Bluetooth device and can obtain relevant information for subsequent connection and operation.

[0075] S4. The end cover receives the Bluetooth name and Bluetooth MAC address of the idle Bluetooth device broadcast by Bluetooth, and caches the Bluetooth name and Bluetooth MAC address of the idle Bluetooth device; based on the Bluetooth name and Bluetooth MAC address of the idle Bluetooth device, the end cover sends its own Bluetooth name and Bluetooth MAC address to the idle Bluetooth device.

[0076] S5. After receiving the response data, extract the Bluetooth name of the end cover from the response data; determine whether the format of the Bluetooth name is a combination of a number and a phase; if not, discard the response data; if so, determine whether the number matches the locally stored number; if so, send a request to establish Bluetooth communication based on the response data; if not, discard the response data.

[0077] Specifically, once the response data is received from the Bluetooth device, the first task is to parse the data to extract key information. In this scenario, the Bluetooth name of the end cap is extracted from the response data. The Bluetooth name is typically a string containing the device's identification information.

[0078] After extracting the Bluetooth name, the next step is to verify that the name format meets the expected specifications. That is, a Bluetooth name should consist of a number and a phase. Therefore, you need to write a validation function to check whether the Bluetooth name format is correct.

[0079] If the format of the Bluetooth name does not conform to the combination format of the number and phase, it means that the response data does not come from the expected end-cap device, or an error occurred during the data transmission. In this case, in order to maintain data accuracy and system stability, the response data should be discarded and continue to wait or search for other valid responses.

[0080] If the Bluetooth name format is correct, further verification is required to verify that the ID matches the locally stored ID. This locally stored ID is the ID of the electrical box where the dedicated transformer acquisition terminal is located. By comparing the ID in the response data with the locally stored ID, it is possible to determine whether the end cap device is a registered end cap in the same electrical box.

[0081] If the numbers match, the response data is considered valid. Next, a request to establish Bluetooth communication is sent based on the response data. This request contains the parameters and instructions required to establish a connection, allowing for subsequent communication and data exchange with the end cap device.

[0082] However, if the numbers do not match, then this means that the response data may come from an unknown device or is an incorrect response. In this case, in order to maintain the security and stability of the system, this response data should also be discarded and continue to wait or search for other valid responses.

[0083] Through this series of verification and judgment processes, it can be ensured that the dedicated transformer acquisition terminal establishes Bluetooth communication with the end cap in the same electrical box, avoiding connection to the end cap in other electrical boxes.

[0084] S6. Send a request for establishing Bluetooth communication to the end cover based on the response data, and establish a Bluetooth channel between the idle Bluetooth device of the dedicated transformer acquisition terminal and the end cover.

[0085] The Bluetooth name and Bluetooth MAC address of the end cap are extracted from the response data, and the phase is parsed from the Bluetooth name of the end cap; based on the pre-set correspondence between Bluetooth devices and phases, and the phase in the Bluetooth name of the end cap, the target Bluetooth device is filtered out from the idle Bluetooth devices; the Bluetooth name and Bluetooth MAC address of the target Bluetooth device are encapsulated into the request, and the request is sent to the end cap.

[0086] The corresponding relationship between the Bluetooth device and the phase is, for example, Bluetooth device 1 - phase A, Bluetooth device 2 - phase B, and Bluetooth device 3 - phase C.

[0087] If the target Bluetooth device corresponding to the response data cannot be matched, the target Bluetooth device is queried from the Bluetooth devices in the connected state. If the target Bluetooth device in the connected state is queried, the target Bluetooth device is controlled to disconnect, and then the Bluetooth name and Bluetooth MAC address of the target Bluetooth device are encapsulated into the request, and the request is sent to the corresponding end cover.

[0088] S7. Obtain the transformer monitoring data collected by the end cover through the Bluetooth channel.

[0089] Real-time data sent by the end cover is received through a Bluetooth channel, the real-time data carries an identification code and includes current data and voltage data; based on a Bluetooth name corresponding to the Bluetooth channel, the real-time data is stored in a storage path corresponding to the Bluetooth name.

[0090] To ensure data accuracy and traceability, the real-time data sent by the end cap typically carries a unique identifier. This identifier might be the device's serial number, a timestamp, or other information that uniquely identifies the data transmission. By analyzing this identifier, we can ensure data integrity and accuracy, and effectively manage and analyze it.

[0091] When the system receives real-time data, it needs to determine the data storage path based on the Bluetooth name corresponding to the Bluetooth channel. By parsing the Bluetooth name, it can determine which end cap device the data comes from and find the corresponding storage path.

[0092] After the storage path is determined, the received real-time data is stored in the path. The storage method is text file.
