Abstract

The utility model discloses a monitoring system of fire-fighting equipment power supplies. The monitoring system comprises a host (100) and a plurality of branch machines (200). The host (100) includes a host alarm unit (102). Each branch machine (200) is connected with a fire-fighting power supply (400). In the monitoring system of the fire-fighting equipment power supplies, when detecting any abnormity of a fire-fighting power supply (400), the corresponding branch machine (200) gives the host (100) an alarm signal, and the host (100) gives an alarm. Meanwhile, a monitoring circuit (300) is disposed below the host (100). When any power supply occurs to the host (100), an electromagnet (504) connected with the power supply of the host (100) is powered off and the electromagnet (504) and an iron block (506) are separated under the action of a spring (507), and an elevating device (500) is caused to elevate, a conductive block (510) is disengaged from a gap (602) of the monitoring circuit (600), and the monitoring circuit (600) is thus powered off. A worker can determine whether the host (100) is supplied with power normally or not according to on-off states of a lamp (604) on the monitoring circuit (600). Therefore, a case that the power supply of the fire-fighting power supplies is misjudged to be normal because the host (100) cannot receive an alarm signal when a branch machine (200) gives an alarm upon any abnormity in power supply to the host (100) is prevented, and immeasurable loss caused by unusable fire-fighting equipment upon the arrival of a real fire disaster is thus prevented.
