Description
Technical field
The utility model belongs to protective relaying device technology, more particularly to a kind of type information of protective relaying device is long-range
Acquisition device.
Background technology
With continuing to develop for automatic technology, the technology that substation is used is also increasingly complicated, and equipment is also increasingly various
Change, the maintenance of transformer station also becomes complicated simultaneously.Wherein protective relaying device is the important dress for influenceing power system normally to run
Put, its printing function carried is applied in many occasions, and such as device is in the debugging stage, it is necessary to print test report and waveform；
The stage put into operation, it is necessary to the information such as version, definite value, parameter of printing equipment and achieve；At the scene the operation phase, there is device alarm
Or failure, it is also desirable to real time print is exported, and is used as anomaly analysis data etc..But as transformer station's important information analysis of data after
Electrical protective device type information but needs for artificial to scene acquisition, it is impossible to which be sent to distal end scheduling in time makes for accident analysis
With causing protection device information monitoring, the automatization level of the system failure and protection act behavioural analysis and management relatively lags behind.
Utility model content
The technical problems to be solved in the utility model：A kind of type information of protective relaying device is provided and remotely obtains dress
Put, with solve prior art protective relaying device printing can only live local printing, type information needs artificial to scene
Acquisition can not be sent to distal end scheduling in time and be used for accident analysis, cause protection device information monitoring, and the system failure and protection are dynamic
The automatization level for making behavioural analysis and management such as relatively lags behind at the technical problem.
Technical solutions of the utility model：
A kind of long-range acquisition device of the type information of protective relaying device, it turns RS485 converters including RS232,
RS232 turns RS485 converters and is connected on the signal wire of protective relaying device and printer；RS232 turns RS485 converters and number
Connected according to collecting unit.
RS232 turns RS485 converters and connected by the RJ45 interfaces of DB9 or DB25 interfaces and data acquisition unit.
RS232 turns to be provided with photoisolator on RS485 converters.
The beneficial effects of the utility model：
The utility model turns RS485 by installation RS232 on the signal wire between protective relaying device and printer and adopted
Storage, long-range data acquisition list is delivered to by the type information of protective relaying device by being converted to RS485 forms by RS232 forms
Member, realize remote collection and the printing of protective relaying device type information, and the protective relaying device for solving prior art is beaten
Print can only live local printing, type information needs artificial not being sent to distal end scheduling in time to scene acquisition and supply accident analysis to make
With causing protection device information monitoring, the automatization level of the system failure and protection act behavioural analysis and management relatively lags behind
Etc. technical problem.
Brief description of the drawings：
Fig. 1 is structure chart of the present utility model.
Embodiment
A kind of long-range acquisition device of the type information of protective relaying device（See Fig. 1）, it turns RS485 conversions including RS232
Device, RS232 turns RS485 converters and is connected on the signal wire of protective relaying device and printer；RS232 turns RS485 converters
It is connected with data acquisition unit.
RS232 turns RS485 converters and connected by the RJ45 interfaces of DB9 or DB25 interfaces and data acquisition unit.In order to
The reliability and accuracy of data transmission procedure are improved, the utility model turns RS485 converters by local printing using RS232
The RS-232C signals of machine are converted to RS-485 signals, then give collecting unit RS-485 signals.
RS232 turns to be provided with photoisolator on RS485 converters, and photoisolator is arranged on before data acquisition unit
End, solves influence of the utility model bypass collection to original circuit.
In order to ensure more accurately to receive data, the utility model is physically improving line interface side
Formula.When protective relaying device is to printer transmission data, RS-232C serial communication buses are used, RS-232C is U.S.'s electricity
Sub- TIA EIA（Electronic Industries Association）With combining Bell System, modem producer
And the standard for serial communication that terminal manufacturer formulates jointly.Because RS232 is single ended input output, duplex
Digital ground wire is at least needed during work, three lines of line and acceptance line are sent（Asynchronous transmission）, other control lines can also be added to complete
The function such as synchronous.It has that transmission cable length is less than 50 feet, altogether Earth noise and is unable to suppression common mode, so
When by the way of bypass collection, transmission line easily causes the problem of receiving error in data when being more than 50 feet.
In order to solve these problems, the utility model strengthens communication bus by the way of RS-232C combinations RS-485
Flexible and reliability.The maximum transmission distance standard value of RS-485 interfaces is 4000 feet, actually up to 3000 meters, separately
Outer RS-232-C interfaces only allow to connect 1 transceiver in bus, i.e., single station ability.And RS-485 interfaces are in bus
Allow to connect up to 128 transceivers.There is multistation ability, such user can be using single RS-485 interfaces easily
Set up device network.Because RS-485 interfaces have in good noise immunity, long transmission range and multistation ability etc.
State advantage.
The utility model in actual environment by using, it can be seen that is not influenceing the original printer work of protective relaying device
On the basis of work, system completes the real-time collection of print data, by gather conversion after e-file display result and
Printer paper document is compared：Tool has the advantage that：1st, the character and picture material of e-file, which are shown, becomes apparent from；2nd, electronics
File layout structure can be preferably consistent with printing paper document；3rd, e-file display speed is significantly larger than printer
Print speed；4th, e-file is easy to the real-time teletransmission of information and shared.
The utility model realizes unified management and storage to the print data of protection device, reduce original manpower,
The waste of material resources, improves the production efficiency and the efficiency of management using unit.
