The parameter signal for collecting is transformed into the analog signal that A/D converter (12) is received, and A/D converter (12) is realized analog signal
Data signal is converted to, data encoder (111) is encoded to data signal, fiber optic transmitter A (14) passes through a light again
Fine (2) are by coded data incoming data memory module (3)；
Step 3：Fiber optic receiver A (33) in data memory module (3) receives fiber optic transmitter A in data acquisition module (1)
(14) coded data for spreading out of, fiber data processor (312) is decoded to coded data, SDRAM read-write controllers (314)
In data Cun Chudao SDRAM memories (35) that will be decoded under access control, the cooperation of address control unit (316), it is right to realize
The collection of data in IGBT module, while clock chip (32) is realized to clock in the presence of clock chip controller (311)
The reading of information, fiber optic transmitter B (34) is by clock signal by another optical fiber (2) incoming data acquisition module (1)
Clock signal is input to A/D converter by fiber optic receiver B (15), fiber optic receiver B (15) by A/D controllers (112)
(12) data acquisition module (1) and data memory module (3) data message synchronization, there is provided clock information, are realized；
When access control, address control unit (316) detect IGBT module to break down, in SDRAM read-write controllers (314)
Cooperation under will be buffered in 5 second datas before the IGBT module failure in SDRAM memory (35) and read, and read and write in FLASH and control
In storing data into FLASH memory (36) under the cooperation of device (315) processed；
Step 4：When the transmission that communication controler (317) receives data transmission module (4) is asked, FLASH storages are will be stored in
Fault data in device (36) is sent to host computer or wireless by usb communication chip (41) or GPRS wireless communication modules (43)
Receiving terminal, realizes the collection to fault data in IGBT module.
