The invention discloses a KNX intelligent switch panel
system and a working method, and relates to the technical field of KNX intelligent switch panels. The
system comprises a KNX subsystem which is powered by a KNX main power supply and comprises a KNX
transceiver; the MCU subsystem is powered by an auxiliary power supply, and the MCU subsystem comprises an MCU module and a key module; the isolation module is respectively connected with the KNX
transceiver and the MCU module and is used for carrying out isolation communication; the reset module is connected with the MCU module of the MCU subsystem and used for detecting the
voltage of the auxiliary power supply, and when the
voltage of the auxiliary power supply is smaller than a set value, a reset
signal is sent to enable the MCU module to stop sending the
serial port data; and when the power ok
signal is at a low level, the MCU module stops sending the
serial port data. According to the KNX intelligent switch panel
system and the working method provided by the invention, data interaction is performed only when the
voltage of the KNX
transceiver and the voltage of the MCU module are normal, so that part of functions of the panel are prevented from being abnormal due to front and back power-on, and the power supply cost is saved to the maximum extent.
