Abstract

The present invention discloses a method for transmitting parallelization signals of uninterruptible power supplies, which firstly performs a serialization process on parallelization signals by a logic processing unit and then performs synchronous transmission of the parallelization signals of respective node units over a bus. The method for serial transmission of parallelization signals of uninterruptible power supplies according to the invention can be implemented with easy wiring and can achieve a strong anti-interference ability, ensure real time signal transmission over a guaranteed transmission distance and identify conveniently the failure of a parallelization line while satisfying fundamental transmission demands.

Claims (17)

1. A method for transmitting parallelization signals of uninterruptible power supplies, comprising firstly performing a serialization process on the parallelization signals by a logic processing unit and then performing synchronous transmission of the parallelization signals of respective node units over a bus

the node units comprising a master node unit and a slave node unit;

wherein the master node unit transmits synchronization information at a specific timing, and the slave node unit receives the synchronization information in real time; and after the master node unit transmits the synchronization information and the slave node unit receives the correct synchronization information, the synchronization succeeds, and then the respective node units transmit the parallelization signals in series in the same sequence of bits.

2. The method for transmitting parallelization signals of uninterruptible power supplies according to claim 1 , wherein the logic processing unit is a CPLD or an FPGA or a microcontroller.

3. The method for transmitting parallelization signals of uninterruptible power supplies according to claim 2 , wherein the transmission over the bus is implemented by a “line-AND” circuit unit.

4. The method for transmitting parallelization signals of uninterruptible power supplies according to claim 2 , wherein the transmission over the bus is implemented by a “line-OR” circuit unit.

5. The method for transmitting parallelization signals of uninterruptible power supplies according to claim 1 , wherein the master node unit is derived through power-up competition or hardware configuration.

6. The method for transmitting parallelization signals of uninterruptible power supplies according to claim 5 , wherein the transmission over the bus is implemented by a “line-AND” circuit unit.

7. The method for transmitting parallelization signals of uninterruptible power supplies according to claim 5 , wherein the transmission over the bus is implemented by a “line-OR” circuit unit.

8. The method for transmitting parallelization signals of uninterruptible power supplies according to claim 1 , wherein the synchronization information is a series of symbols different from valid data.

9. The method for transmitting parallelization signals of uninterruptible power supplies according to claim 8 , wherein the transmission over the bus is implemented by a “line-AND” circuit unit.

10. The method for transmitting parallelization signals of uninterruptible power supplies according to claim 8 , wherein the transmission over the bus is implemented by a “line-OR” circuit unit.

11. The method for transmitting parallelization signals of uninterruptible power supplies according to claim 1 , wherein the transmission over the bus is implemented by a “line-AND” circuit unit.

12. The method for transmitting parallelization signals of uninterruptible power supplies according to claim 11 , wherein the “line-AND” circuit unit is a CAN transceiver.

13. The method for transmitting parallelization signals of uninterruptible power supplies according to claim 1 , wherein the transmission over the bus is implemented by a “line-OR” circuit unit.

14. The method for transmitting parallelization signals of uninterruptible power supplies according to claim 13 , wherein the “line-OR” circuit unit is a CAN transceiver.

15. The method for transmitting parallelization signals of uninterruptible power supplies according to claim 1 , wherein the respective nodes can transmit their own parallelization information concurrently.
