Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of linkage control, and specifically discloses a multi-phase constructed fire alarm disposal system. Background Art
[0002] According to the current standard "Design Fire Protection Standard for Thermal Power Plants and Substations", the fire control room should be arranged together with the centralized control room. According to the "General Code for Building Fire Protection" (implemented on June 1, 2023), the fire control room is required to be located on the first floor or underground floor of the building, and the evacuation door should lead directly to the outdoors or the emergency exit.
[0003] Based on the above design background, the fire control room of thermal power plants that have been built or have started construction before June 1, 2023 will be combined with the centralized control room and located on the operation floor. For thermal power plants that start expansion after June 1, 2023, the fire control room will be set up separately and located on the first floor of the building.
[0004] Large thermal power plants are often built in phases. When the second phase is constructed, the flow and head of the first phase fire pump will be recalculated to see if they can meet the requirements of the second phase. If the flow and head are not enough, the fire pump needs to be replaced; if the flow and head are enough, the fire pump of the first phase can be used directly. In short, the fire pumps of the first and second phases of the thermal power plant are shared by the two phases regardless of whether they are replaced or not. However, the smoke and exhaust fans and various monitoring facilities are configured separately for the two phases.
[0005] If the linkage of fire alarm handling facilities is to be achieved in multiple phases of construction, it is often necessary to reintegrate the facilities that have been built in the early stage into the new system, which brings great waste. At the same time, the operators have to familiarize themselves with the monitoring plan of the new system again. In the process of switching between the old and new systems, it is easy to cause misoperation in emergency situations due to unfamiliarity. Utility Model Content

[0008] Preferably, the monitoring terminals and smoke and exhaust fan operating terminals of the first-phase fire control unit and the later-phase fire control unit are respectively electrically connected to the corresponding equipment on site, and only the fire water pump operating terminal of the first-phase fire control unit is electrically connected to the fire water pump on site.
[0009] Preferably, the same type of equipment in the communication facility and the monitoring terminal establish signal connections respectively through optical cables; the same type of equipment in the operation terminal establish signal connections respectively through hard wiring.
