Abstract
A data repeater of an infrared electric energy meter comprises an infrared acquisition module, a main control module and a host communication module, and is characterized in that the infrared acquisition module, the main control module and the host communication module are connected in sequence. The main control module controls the infrared acquisition module to obtain on-spot electric energy data information, and then the host communication module enables all electric energy data acquired on spot to be transmitted to a host.
Description
Technical field
The utility model relates to a kind of data transmission device, especially infrared 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 infrared electric energy meter headend, adopts infrared 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: infrared electric energy meter headend; Comprise infrared acquisition module, main control module, host computer communication module; It is characterized in that infrared acquisition module, main control module, host computer communication module connect successively.Main control module is transferred in the main frame through host computer communication module each energy data with collection in worksite after infrared acquisition module obtains on-the-spot energy data information through controlling.
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, infrared electric energy meter headend comprises infrared acquisition module 1, main control module 2, host computer communication module 3, it is characterized in that, infrared acquisition module 1, main control module 2, host computer communication module 3 connect successively.Main control module 2 is transferred in the main frame through host computer communication module 3 each energy data with collection in worksite after infrared acquisition module 1 obtains on-the-spot energy data information through controlling.
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.MSP430F149 carries out data communication through RS232 communication module and main frame.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.The infrared communication interface circuit comes down to by infrared emission tube; Infrared receiver; The photosignal change-over circuit that transmission gate is formed; Circuit design is relevant with the transmitting range of actual needs, and this infrared communication module has been isolated being electrically connected better anti-jamming capability and really realizing infrared transmission of two infrared equipments.The infrared emission circuit; Mainly by rejection gate, the P1.1 generation carrier signal of each one composition of infrared transmitting tube and amplifying triode MSP430F149 single-chip microcomputer plays the carrier modulation effect through rejection gate CD4071 to TXD transmission data and through infrared transmitting tube and amplifying triode the ammeter ' s reading meter device is sent data-signal at last.Infrared receiving circuit; Mainly forming NJL41 series by NJL41V328 is the integrated infrared receiver of the new release of JRC; Integrating infrared ray receives and amplifies; Without any need for outward element, just can accomplish from infrared ray and receive the output all working compatible, and volume is the same with common plastic packaging triode size with the TTL level signal.Therefore; It is suitable for various infra-red remote controls and infrared data transmission; Be the ideal element that replaces infrared reception amplifier such as reception diode, the exchanges data that NJL41V328 is used between transponder and the ammeter ' s reading meter device has realized the RFDC between transponder and the ammeter ' s reading meter device.
