Synthesized alarming system of miniature transformer station

The present invention relates to a synthesized alarming system of a miniature transformer station. The synthesized alarming system of the miniature transformer station comprises the following structures: a charger is configured to supply power to a lithium battery pack; the lithium battery pack is configured to supply power to a two-position relay and a 5V boost module; the two-position relay is configured to control a resetting test button, an alarm sound IC and a power amplification module, and the alarm sound IC is configured to send signals to the power amplification module; the power amplification module is configured to connect with a loudspeaker; the 5V boost module is configured to connect with a voltage indication circuit; the voltage indication circuit is configured to connect with a LED indicating lamp; and an input terminal is arranged at the two-position relay. According to the invention, total motion nodes of accident protection in the distance are acquired through cables and the alarming system gives an alarm when the nodes are moving. Through adoption of a hybrid power supply mode, the system may automatically switch to an internal power supply for supplying power at the loss of an external power supply, and internal battery may be automatically charged when the external power supply is connected. The synthesized alarming system of the miniature transformer station is small in size which is similar to the size of a suitcase, and is easy to carry.
