Description

Technical Field

[0001] The present invention belongs to the technical field of electrical equipment analysis and monitoring, and in particular relates to fire pump analysis and monitoring technology. Specifically, the present invention is a BIM-based intelligent analysis and monitoring system for building electrical equipment. Background Art

[0002] With the development trend of gradually improving the construction level of the construction industry, building construction is gradually tending towards intelligence. Fire pumps, as an important part of building construction, can improve their operation level through integration with BIM technology. Therefore, in order to ensure the smooth operation of fire pumps in buildings, they need to be monitored and analyzed.

[0003] At present, the monitoring and analysis of building fire pumps are mainly divided into two directions. The first direction is the operating environment of the pump room, and the second direction is the pump operation information. Among them, the operating environment mainly monitors and analyzes the temperature and humidity, water leakage, noise, etc. inside the pump room, and the water inside the pump mainly monitors the liquid level, water pressure, pump energy consumption, etc. However, as a necessary equipment for emergency rescue, the current monitoring of these two directions cannot guarantee its stability and smoothness in emergency rescue work, which is specifically reflected in the following aspects:

[0004] 1. Fire pumps are devices with many structures. Their motors, bearings, and impellers are structures with many operations, and their operating conditions will affect the firefighting level. Currently, there is no separate monitoring of the structures of fire pumps, which cannot improve the comprehensiveness and reliability of fire pump operation safety monitoring, nor can it improve the timeliness of detecting and handling abnormal conditions of fire pump structures, and cannot reduce the subsequent maintenance cost and difficulty of fire pumps.

[0005] 2. The associated cable area corresponding to the fire pump is not only a high-incidence place for fires, but the status of the cables also directly determines the feasibility of firefighting operations. Currently, there is no monitoring and analysis of the cables corresponding to the fire pumps, which cannot improve the stability of the operation of the fire lines, nor can it improve the smoothness of firefighting operations, and at the same time cannot reduce the potential safety hazards of the operation of the fire lines;

[0006] 3. The current monitoring and analysis of fire pumps is not combined with BIM technology. It is a conventional analysis technology. It not only cannot provide a reliable decision-making basis for the installation design of fire pumps in similar buildings, but also cannot improve the intuitiveness of fire pump early warning, which is not convenient for maintenance personnel to carry out fire pump maintenance work.

[0104] The fire pump comprehensive status analysis module is used to analyze the structural status, cable status and working status of each fire pump according to the structural safety assessment index, cable safety assessment index and working safety assessment index corresponding to each fire pump. If a certain status of a fire pump is abnormal, the fire pump is recorded as an early warning fire pump, and then the early warning feedback and marking module is started;

[0105] Exemplarily, the structural status, cable status and working status corresponding to each fire pump are analyzed, and the specific analysis process is:

[0106] The structural safety assessment index corresponding to each fire pump is compared with the set standard structural safety assessment index of the fire pump.
