Embodiment 1

[0059] Such as figure 1 As shown, this implementation provides a power meter calibration tool based on low-power Bluetooth communication. The meter calibration tool includes: a Bluetooth master module 1, a plurality of Bluetooth transparent transmission slave modules 2, a main control unit 3, and a first storage module 6, and the second storage module 7.

[0060] Among them, the Bluetooth master module 1 is connected with a computer terminal running meter calibration software, and is used to send the meter calibration command generated by the meter calibration software; the Bluetooth master module 1 is also paired with multiple Bluetooth transparent transmission slave modules 2 to form multiple A link for data or instruction transmission.

[0061] The number of bluetooth transparent transmission slave modules 2 is not less than the number of multiple electric energy meters to be calibrated simultaneously in each round.

[0062] The main control unit 3 is connected to the ele...

Embodiment 2

[0082] Such as figure 2 with 3 As shown, the difference between this embodiment and Embodiment 1 is: in this embodiment, the main control unit 3 is also electrically connected to the indicator light 5 module; the number of indicator lights 5 is the same as the number of bluetooth transparent transmission slave modules 2 in the meter calibration tool The same, and a one-to-one correspondence relationship is established between the two; the main control unit 3 sends a control command to the indicator light 5 module, and when each Bluetooth transparent transmission slave module 2 is matched with the Bluetooth master module 1, according to whether the connection is successful Send out the first indication signal; when the main control unit 3 copies the meter addresses of the electric energy meters, send out the second indication signal according to whether the copy can be successfully copied.

[0083] The use of the indicator light 5 can facilitate the matching and docking of th...

Embodiment 3

[0085] Such as Figure 4 As shown, this embodiment provides a meter calibration method based on the Bluetooth low-power communication-based electric energy meter calibration tool, which is applied to the energy meter calibration tool based on low-power Bluetooth communication in Embodiment 2. The meter calibration The method includes the following steps:

[0086] S1: The energy meter establishes a two-way communication connection with the main control unit 3 through the 485 communication module 4 at each meter calibration station;

[0087] S2: Main control unit 3, 485 communication module 4 and Bluetooth transparent transmission slave module 2 are powered on, and Bluetooth transparent transmission slave module 2 starts broadcasting and waits for connection;

[0088] S3: The Bluetooth main module 1 is powered on, and the Bluetooth main module 1 scans and matches and connects the Bluetooth transparent transmission slave module 2 in the broadcasting state. The scanning and match...

Abstract

The invention relates to the field of power equipment, and in particular relates to an electric energy meter calibration tool based on low-power-consumption Bluetooth communication and a meter calibration method thereof. The meter calibration tool comprises a Bluetooth main module, a plurality of Bluetooth unvarnished transmission slave modules, a main control unit, a first storage module and a second storage module. The Bluetooth main module is connected with a computer terminal for operating meter calibration software, and is used for sending a meter calibration instruction generated by the meter calibration software; the Bluetooth main module is further in pairing connection with the plurality of Bluetooth unvarnished transmission slave modules, and the main control unit is in bidirectional communication connection with each to-be-calibrated electric energy meter through a 485 communication module and is electrically connected with each Bluetooth unvarnished transmission slave module; the first storage module is electrically connected with the Bluetooth main module; the first storage module is used for storing an MAC address table; the second storage module is electrically connected with the Bluetooth main module; the second storage module is used for storing a link binding comparison table. According to the invention, the technical problem that high-speed and high-concurrency meter calibration and meter reading of electric energy meters are difficult to realize is solved.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an electric energy meter calibration tool and a meter calibration method based on low-power bluetooth communication. Background technique [0002] After the production and assembly of the electric energy meter is completed, it needs to be checked to ensure the consistency of the factory performance of each electric energy meter. In the traditional energy meter calibration process, the meter calibration equipment uses long-distance 485 communication or HPLC (broadband power line carrier) communication to read the information of the energy meter or send the calibration command. These two meter calibration devices and methods have the following disadvantages: (1) When calibrating the meter through the 485 communication connection, since a large number of electric energy meter products usually need to be calibrated at the same time during the meter calibrating process, this process ...
