Description

Interface device special for transformer substation fire-fighting main network Technical Field The invention relates to the technical field of fire safety management of substations, in particular to a special interface device for a substation fire-fighting main network. Background In the current transformer substation, a plurality of fire-fighting hosts exist, and a main transformer fire-extinguishing comprehensive host, a special gas fire-extinguishing host for a capacitor room and the like are common. The main transformer fire extinguishing comprehensive host generally has the function of monitoring fire conditions and alarms in other fire protection areas of the comprehensive building in the transformer substation. Because most substations are unattended substations, the fire alarm signals of the substations need to be connected into a remote monitoring system, and remote monitoring personnel are on duty for 24 hours continuously. In the actual operation process, the signals connected into the remote monitoring system only have the combined signals of fire and fire alarms, so that the remote monitoring system can only monitor the fire alarm information, but the fire information (such as when, where and equipment alarms and the like of the fire alarms) cannot be sent into the remote monitoring system, and the main reason is that a plurality of manufacturers of fire-fighting hosts in the transformer substation exist, and the fire-fighting transmission protocols of different manufacturers are incompatible. Therefore, it is necessary to unify the transmission protocols of various fire information as much as possible, and to transmit both fire information and fire information to a remote monitoring system in time. Disclosure of Invention The technical problem to be solved by the embodiment of the invention is to provide the interface device special for the substation fire-fighting main network, which can unify the transmission protocols of various fire-fighting information and timely transmit the fire-fighting information and fire-alarm information to a remote monitoring system.
