Abstract

The invention discloses a power-off monitoring device and method and external protection equipment. The power failure monitoring device is used for monitoring and warning abnormal power failure monitoring of external protection equipment and comprises a power taking circuit, a power taking connection module and a warning module, the power taking circuit is used for connecting the power failure monitoring device to a special power taking port, and the special power taking port is not connected to a power supply circuit of the external protection equipment; the power-taking connection module is used for monitoring whether the external protection equipment is powered off abnormally or not and connecting the power-taking circuit when monitoring that the external protection equipment is powered off abnormally, so that the power-off monitoring device is started by taking power from a special power-taking port; and the warning module is used for sending warning information when the power-off monitoring device is started. Through the mutual exclusion type power supply design, the special power taking port can be switched on to work when the external protection equipment is powered off abnormally, so that the safety problem caused by powering off the external protection equipment is effectively prevented.
