Abstract
A modular UPS system includes at least two power devices, a controlling device, and a serial bus. The power device is configured to receive control status information transmitted by the controlling device. The power device is configured to transmit a status signal data frame to the serial bus according to the control status information when determining that a current period is a first preset period, where the status signal data frame includes an identifier field, the identifier field includes a status signal data area, and the status signal data area is used to store a data value of a status signal. The serial bus is configured to receive status signal data frames transmitted by the at least two power devices, and transmit status signal data frames with a same value in status signal data areas to the controlling device in parallel.
