Abstract
The invention provides a programmer for electric energy meters, wherein the programmer adopts a half-duplex operation mode of a master-slave structure at a communication software-programmed data link layer, the programmer is taken as a master station, and the electric energy meters are taken as slave stations; each electric energy meter is provided with respective address coding; the establishing and the relieving of a communication link are controlled by information frames sent by the master station; each frame consists of seven fields of a frame start character, a slave station address field, a control code, a data field length, a data field, a frame information longitudinal check code and a frame ending character. When the programmer transmits data, before the master station transmits the frame information, four bytes of FEH are firstly transmitted, so that a receiving party is awakened. Data identifying and programming of the programmer distinguishes different data items by four bytes. The each multi-functional table programming software is unified by the programmer, so that the problem that the electric energy meter programmers of each electric energy meter factory are independently uncurrent can be solved, and the technical specification of the multi-functional table electric energy meter programmer programming software can be unified. The programmer is used for programming various electric energy meters.
Description
Technical field
The present invention relates to a kind of electric energy meter programming device, belong to the electric-power metering technical field.
Background technology
Along with the application of multifunctional electric energy meter more and more widely, multifunctional electric energy meter programming, the workload of checking meter are also increased day by day.From the needs of host computer, concentrator and electric energy meter communication, country issued DL/T645-1997 electric energy meter communication protocol in 1997.But because these stipulations are formulated the time early, along with the expanded function of multifunctional electric energy meter is increasing, these stipulations can not satisfy each item demand of continuous development.So the numerous and confused communications protocol of formulating separately of each province Utilities Electric Co., electric energy meter supplier, thereby each tame communication protocol has nothing in common with each other, and all there are bigger difference in different manufacturers, the electric energy meter communication protocol of different model, structure.
Multifunctional electric energy meter is being programmed, checking meter, when testing accuracy and function, all need use the special palm programmable device of producer that electric energy meter is carried out communication and control.Though each ammeter manufacturer has all developed programming, the palm machine of checking meter to our factory's model electric energy meter now; But each electric energy meter manufacturer all adopts different programming, check meter electric energy meter programming device and programming software, the self-defining communication modes of use and communications protocol; Even in same ammeter factory, the communication protocol and the software of the electric energy meter of different model and electric energy meter programming device all have nothing in common with each other.In Jiangxi electrical network installation and operation have that Changsha wasion, hundred Fuhuas are grand, nearly 20 merchants of household electrical appliances Watch Factory such as Holley's instrument, Dongfang Electronics, Nanjing, Shanghai, Shenzhen are held bright, Zhuhai state survey, ZhangZhou section ability, section's land electronics, the electric energy meter of kind of model surplus in the of nearly 80.Operating personnel need learn to use the method for tens kinds of programmings, programmable device like this, have strengthened the use difficulty, have also strengthened the probability of makeing mistakes simultaneously, have increased workload, cause programming, meter reading personnel to feel exhausted inefficiency.
In order to change this situation, the present invention proposes a kind of new way: unified electric energy meter programming device is to electric energy meter programming, the software specifications of checking meter, and takes into account the multifunctional electric energy meter of installation and operation, makes this standard adaptation any multifunctional meter in operation.Regroup a cover palm machine programming, the software of checking meter, can check meter various types of electric energy meter programmings.Operating personnel avoid the generation of faulty operation as long as the operation of a program of study is increased work efficiency, and reduce cost, and reduce the use amount of palm machine, reduce production costs.
Summary of the invention
The objective of the invention is: disclose a kind of electric energy meter programming device; Unified each multifunctional meter programming software; Solve the independent separately mutual uncurrent problem of ammeter programmable device of each ammeter factory now, the technical manual of unified multifunctional meter electric energy meter programming device programming software, the needs of adaptive technique management.
Technical scheme of the present invention is, sets up the electric energy meter programming device to electric energy meter programming, the software specifications of checking meter, and takes into account the multifunctional electric energy meter of installation and operation, makes it to adapt to any multifunctional meter in operation.
The present invention's data link layer in communication software is write adopts the half-duplex operation mode of main-slave structure, is main website with the programmable device, and electric energy meter is a slave station; Each electric energy meter all has geocoding separately; The foundation of communication link is controlled by the information frame that main website sends with releasing; Every frame is made up of start-of-frame, tributary address territory, control code, data field length, data field, frame information longitudinal check sign indicating number and 7 territories of frame end symbol.Every part is made up of some bytes; The communication byte format adopts every byte to contain 8 binary codes, adds a start bit (0), even parity bit and a position of rest (1) during transmission, totally 11; D0 is the least significant bit (LSB) of byte, and D7 is the highest significant position of byte.Pass low level earlier, the back passes high-order.
During data transmission, before main website transmit frame information, send 4 byte FEH earlier, to wake the take over party up; Order of transmission adopts all data item all to transmit low byte earlier, and upper byte is transmitted in the back.Each byte adds 33H and redispatches during transmission, and each byte deducts 33H and re-uses during reception.
The Data Identification coding adopts four bytes to distinguish the different pieces of information item, and nybble is used DI respectively
