Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described:
As it is shown in figure 1, a kind of fiber optical transceiver, including far-end independence photoelectric conversion unit 1, power subsystem the 2, first photoelectricity
Converting unit the 3, second photoelectric conversion unit 4, network management unit 5 and electricity mouth unit 17, far-end independence photoelectric conversion unit 1 He
Electricity mouth unit 17 connects the first photoelectric conversion unit 3, the first photoelectric conversion unit 3 and the second photoelectric conversion unit 4 respectively respectively
Connecting network management unit 5, power subsystem 2 connects the first photoelectric conversion unit 3 and network management unit 5, network management respectively
Unit 5 include keyboard unit 10, LCD display unit 11, SD card storage element 12, single machine unit 13, NIU 14,
Temperature detecting unit 15 and minimum system 16, keyboard unit 10, LCD display unit 11, SD card storage element 12, network interface list
Unit 14, temperature detecting unit 15 and minimum system 16 are electrically connected single machine unit 13.
First photoelectric conversion unit 3 is identical structure with the second photoelectric conversion unit 4, becomes including RJ-45 interface 6, isolation
Depressor 7, light transceiving integrated unit 8 and optical & electronic media converter 9, RJ-45 interface 6 connects isolating transformer 7, light transmitting-receiving one
Body unit 8 connects optical & electronic media converter 9.
Far-end independence photoelectric conversion unit connects the first photoelectric conversion unit by optical fiber.
Single machine unit includes LPC2210 chip.
Keyboard unit: the keyboard employing band I2C interface carries out keyboard scan with LED drive chip ZLG7290,
ZLG7290 uses 3.3V supply voltage, and its reset pin is connected with systematic reset signal nRST, while system reset
Reset ZLG7290 chip, the keyboard interrupt output signal of ZLG7290 is connected with the P0.30 of LPC2210, when a key is pressed,
ZLG7290 will export interrupt signal notice LPC2210 chip.ZLG7290 be use its I2C bus (SDA, SCL) with
LPC2210 chip is connected.
SD card storage element: P0.4, P0.5 and P0.6 of LPC2210SPI0 interface receive the corresponding interface of deck, in order to
Making the circuit can be with the interface compatibility of mmc card, two data wire P0.6 and P0.5 of SPI need to connect pull-up resistor respectively.Sheet choosing letter
Number use P0.18.The power supply of card uses controlled manner, and controlable electric current uses p-type metal-oxide-semiconductor 2SJ355, by the P0.17 of LPC2210
Being controlled, when P0.17 exports high level, 2SJ355 turns off, and does not give card power supply；When P0.17 output low level, 2SJ355
Open-minded, power to SD card.Card testing circuit includes two parts: whether card is completely inserted into deck and blocks whether write-protect.Detection
Signal has two pins of deck to export in level mode, when card is inserted into deck and insertion puts in place, touches owing to deck is internal
It is low level that point is connected to GND, P0.19；When card is extracted, this pin has resistance R9 pull-up for high level.
