The invention discloses an emergency power supply device with BAS communication, comprising a battery, a sampling circuit, a control circuit and a control board. The sampling circuit is connected withthe battery and the control board and is used for collecting the voltage of the battery and transmitting the collected voltage to the control board through a BAS communication bus. The control circuit is connected with the battery and the control board and is used for controlling the output of the battery. The control board is connected with the control circuit and is used for receiving the voltage value of the battery collected by the sampling circuit, and controlling the control circuit according to a detected voltage value. The voltage of the emergency power supply device can be detected and the detected voltage value is transmitted to the control board. When the emergency power supply device is in an under-voltage state, a relay coil is de-energized so as to switch a normally-closed relay to an off state. Thus, the protection of the emergency power supply device is realized, and the service life of the emergency power supply device is prolonged.
Description
technical field [0001] The invention belongs to the technical field of emergency power supply and relates to an emergency power supply device with BAS communication. Background technique [0002] With the development of society and the continuous improvement of architectural technology, urban buildings tend to be large-scale, and the development of high-rise buildings has higher and higher requirements for power supply of buildings. The informatization of society and the modernization of buildings make buildings more suitable for The dependence on power supply is also increasing, especially for some important public buildings. Once the power supply is interrupted, it will cause significant political influence or economic loss. If there is a fire, the consequences will be even more unimaginable. [0003] The emergency power supply plays a very important role after the mains power supply is interrupted. The emergency power supply includes chargers, inverters, batteries, and is...
