Failure of TK-WJL-01 embedded recorder is used in today's most advanced DSP and 32 bit embedded CPU, embedded real-time operating system with high performance and design, to adapt to the dynamic fault recording device development demand of electric power system.
The device adopts the latest DSP technology, embedded real-time operating system technology, network communication technology, recording unit dispersed installation structure, combined with the new development of power system, especially the use of embedded real-time operating system, greatly improving the stability and the reliability of device.
Failure of TK-WJL-01 embedded recorder has the following new features:
1) recording unit using real-time operating system for embedded systems and Distributed installation structure, enhance the security of the entire system.
2) a single recording unit consists of 32 bit ARM9 microprocessor, 32M non-volatile FLASH, 64M, SDRAM, 8G and CF card (or 80G disk), completed the uninterrupted recording information of power system, the first to realize the real meaning of the "long wave recorder".
3) implementation of network distributed real recorder target distribution, convenient installation in different locations.
4) through a flexible combination of software, hardware, suitable for the generator, transformer and circuit, according to the demand of flexible change, does not constitute a waste of idle condition.
5) 32 bit ARM9 processor is used to improve the performance of the system.
6) 16 bit high-speed A/D conversion, single channel sampling rate up to 20K.
7) a single recording unit capacity of 16 analog, 32 road input, the maximum integer screen combined capacity of 96 analog, 192 road input.
8) pulse sampling with GPS as the benchmark, makes the data unified time scale, the ease of data analysis.
9) consists of a plurality of data acquisition module through optical fiber or twisted pair local area network, Ethernet TCP/IP protocol for communication support based on the new concept, composition of network information recording system.
10) multi processor data acquisition unit distributed, data collected by each processor unit is synchronized, a recording unit exception does not affect the normal work of other units.
11) dispatching powerful upper analysis software system, using network database management network of the station end device, can really achieve two terminal fault location function conveniently, which is more accurate fault location.
12) the frequency tracking technology, real-time monitoring of system frequency changes, adjust the real-time data sampling interval, can eliminate the calculation error caused by the fluctuation of the fundamental frequency, can guarantee the frequency deviation frequency 50Hz great situation accurately calculate when the system frequency component, harmonic components and sequence components.
13) self check function: in addition to boot a self-test self-test, also timing of each function module, abnormal, indicating lamp will give warning information, and upload information background machine.
