Abstract
The utility model discloses a data transponder of a bluetooth electric energy meter. The data transponder comprises a bluetooth electric energy collection module, a main control module and a host communication module. The bluetooth electric energy meter data transponder is characterized in that the bluetooth electric energy collection module, the main control module, the host communication module and the host are sequentially connected. The main control module acquires the electric energy data information on the spot through the control of the bluetooth electric energy collection module, and all electric energy data which are collected on the spot are transmitted to the host through the host communication module.
Description
Technical field
The utility model relates to a kind of data transmission device, especially bluetooth electric energy meter headend.
Background technology
At present the method for a large amount of manual meterings that exist far can not adapt to the needs of modern management, and the line loss per unit of bringing thus increase the development that also must influence power industry.One of line loss per unit major reason for higher is exactly to check meter, the backwardness of calculating and ladder of management, and the management loss increases, if adopt electric energy meter to copy and accept system automatically.Not only can improve the reliability of operation of power networks greatly, and can make full use of the ability of existing equipment, reduce labour intensity.The core component that electric energy meter is copied and accepted in the system automatically is a headend, through headend with the data forwarding of gathering in main frame.
Summary of the invention
The utility model provides a kind of bluetooth electric energy meter headend, adopts the blue teeth wireless mode to receive the energy data that collects and be forwarded to and carries out analyzing and processing in the main frame.
The utility model solves the technical scheme that its technical matters adopted: bluetooth electric energy meter headend; Comprise bluetooth electric energy acquisition module, main control module, host computer communication module; It is characterized in that bluetooth electric energy acquisition module, main control module, host computer communication module, main frame connect successively.Main control module is transferred in the main frame through host computer communication module each energy data with collection in worksite after obtaining on-the-spot energy data information through control bluetooth electric energy acquisition module.
The beneficial effect of the utility model is, improved electric energy acquisition efficient and convenience, reduce cost again, have higher utility.
Description of drawings
Fig. 1 is the theory diagram of the utility model; Fig. 2 is the electric structural drawing of the utility model.
Embodiment
In Fig. 1, bluetooth electric energy meter headend comprises bluetooth electric energy acquisition module 1, main control module 2, host computer communication module 3, it is characterized in that, bluetooth electric energy acquisition module 1, main control module 2, host computer communication module 3 connect successively.Main control module 2 is transferred in the main frame 1 through host computer communication module 3 each energy data with collection in worksite after obtaining on-the-spot energy data information through control bluetooth electric energy acquisition module 1.
In Fig. 2, electric energy meter is copied and accepted system automatically can realize the exchanges data of main frame and ammeter ' s reading meter device through this headend, is a hyperchannel computer data transmission system.The MSP430F149 single-chip microcomputer that the main control module of the utility model adopts belongs to the MSP430 of Texas Instruments series; MSP430 series is the microcontroller of one group of super low-power consumption; Form with the model that disparate modules is formed to the different application target by multiple; Microcontroller is designed to use the battery long-term work, supply voltage scope 1.8 ~ 3.6V.MSP430F149 have 60KB Flash and 2KB RAM wherein Flash be divided into 120 sections primary memorys (every section 512B) and two segment information storeies (every section 128B) Flash again and can wholely wipe also and can segmentation to wipe this design of hardware and software of giving system and bring great convenience with flexibly in view of the capacity and the characteristics of single-chip microcomputer storer, outsidely be simplified without extended memory and I/O mouth peripherals.The WV of MSP430F149 be 3.3V therefore its I/O level also be the 3.3V logic level and dual serial asynchronous communication mouth arranged with the compatible MSP430F149 of 5V TTL level; The data communication of MSP430F149 and main frame is mainly to be made up of the MAX232/MAX232A reception/transmitter of Maxim company through the RS232 module that the RS232 communication module realizes, Maxim company is in particular the standard that satisfies EIA/TEA 232E and designs.They are widely used in EIA/TIA 232E standard serial communication interface day by day; Low in energy consumption, working power is a single supply, and external capacitor is merely 0.1 F or 1 F adopts the dip form; Receiver is output as superiority such as tristate TTL COMS; For two groups of RS232 reception/transmitter working powers are+5V baud rate height, price is low, can in the system that generally needs serial communication, use.Bluetooth module adopts ROK 101 008 serial Bluetooth chips, defers to bluetooth 1.1 standards, is the communication module of a point-to-multipoint.This module can be simultaneously and in its scope connected 7 bluetooth slave units realize data transmission.The effective radius of Bluetooth communication is relevant with the power of its output: when output power was 2 types (2.5mW/4dB), communication range was 15m; If when increasing its power to 1 type (4mW/20dB), just can make communication range reach 100m.Bluetooth system is supported point-to-point and any communicating by letter to multiple spot.In the connected mode to multiple spot, a plurality of bluetooth units are shared a channel, adopt same frequency hop sequences on one point.The network that each bluetooth equipment constitutes is called pico-network, and bluetooth equipment is realized communication with master-slave mode in the pico-network.
