Description
Technical field
The utility model relates to a kind of electrical network distribution power automation terminal equipment, particularly a kind of self-described ICD file autocoder.
Background technology
Tradition distribution power automation terminal equipment telecontrol information point table, communications parameter etc. are revised the main human configuration of leaning on; The generation of its remote signalling, remote measurement, remote controlled point table will rely on manual manufacture; The technician carries out the off-line transmission through means such as Emails again, after both sides have disposed information point table and local test correctly, carries out pointwise to examination by main website and the station operation both sides of factory again; The probability of makeing mistakes is big, the test period is long; Generally need more than 6 hours, and distribution terminal enormous amount in the electrical power distribution automatization system causes electrical power distribution automatization system to safeguard very difficulty of debugging.In addition; Distribution power automation terminal is because volume restrictions at present; Most of DSP (digital signal processor), microcomputers etc. of adopting are as core processor, and after the tasks such as the collection of processing remote signals, remote measurement AC sampling, remote control output, locality and distant place communication, last traffic handing capacity is very limited; Be difficult to accomplish the device self-described function that satisfies IEC 61850 standards; And in original software code, increase this function, need do substantive test again to original function, workload is very big.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of self-described ability that has is provided, and effectively reduces distribution terminal and inserts debugging work load and debug time, improves the self-described ICD file autocoder of debugging quality.
The purpose of the utility model is achieved in that a kind of self-described ICD file autocoder; Comprise single-chip microcomputer; It is characterized in that scrambler is to be made up of single-chip microcomputer, the digital card of SD, clock crystal oscillator circuit and power supply filtering circuit; Single-chip microcomputer is connected with the digital card of SD and in the digital card of SD, writes data, and single-chip microcomputer also is connected with the serial ports of distribution power automation terminal communication unit, and the digital card of SD is connected with the SPI interface of distribution power automation terminal communication unit; The power supply filtering circuit is connected between power supply and the digital card of SD, and clock circuit is connected with single-chip microcomputer.
The digital card of the single-chip microcomputer of self-described ICD file autocoder and SD is connected, and can activate SD card circuit and in the digital card of SD, write data by the ICD file layout of IEC61850-6 standard, for the digital card of SD external clock is provided simultaneously.Single-chip microcomputer is connected with the serial ports of distribution power automation terminal communication unit, and to read the data that distribution power automation terminal transmits, the digital card of SD is connected with the SPI interface of distribution power automation terminal communication unit, to spread out of the ICD file data to distribution power automation terminal.
Data such as the remote signalling that the utility model can be gathered distribution power automation terminal, remote measurement, remote control; Automatically be generated as the self-described ICD file that satisfies IEC 61850 standards, removed manual manufacture telecontrol information point table and manual testing's point table from and disposed shortcomings such as the inefficiency, the probability of makeing mistakes that are brought are big, test period is long.Adopt the digital card of SD to store data such as the configuration parameter of distribution power automation terminal, failure wave-recording simultaneously, be convenient to the strange land processing of data, the fast quick-recovery after the terminal staging replacing.It is simple in structure, easy to install, dependable performance.
