Detailed Description

The present invention will be described in further detail with reference to examples.

Referring to fig. 1-4, the present invention relates to a building fire data collecting device based on BIM. The device comprises a wireless communication module 1, a smoke sensing module 2, a temperature sensing module 3, a gas sensor 4, a color alarm lamp 5, a fan motor 6 and a processor module 7.

The detection mechanism comprises a smoke sensing module 2, a temperature sensing module 3 and a gas sensor 4. The detection mechanism of the device and the antenna of the wireless communication module 1 are arranged in the cylindrical air channel 62 which is relatively isolated from the external environment, and whether the air channel 62 collects the external environment gas or not is controlled by opening the fan motor 6.

A composite layer 82 consisting of a thermal insulation layer constructed by a 5mm thermal insulation material and a flame-retardant layer constructed by a 3mm flame-retardant material is attached to the inside of the shell 8, the inside of the device is filled with a liquid 83 with high insulation and stability, and the processor module 7 and the power pack 9 are placed in the device. Under the high-temperature radiation of the external environment, the detection system can keep a stable working state. The colored warning lamp 5 generates a highlighted different-color warning signal in the event of a fire and a building environment that is unfavorable for humans, while it provides fault information when the device is commissioned.

The connecting wires of the wireless communication module 1, the smoke sensing module 2, the temperature sensing module 3, the gas sensor 4 and the device internal processor module 7 pass through the bolt 84 and the nut 85 which are made of heat-resistant and flame-retardant materials, and internal electric elements isolate the external environment to a greater extent.

The heat insulation layer material of the composite layer 82 is made of a silicon rubber material, the flame retardant layer material of the composite layer 82 is made of an aerogel felt material, and the insulating liquid 83 arranged in the composite layer is made of high-quality transformer oil. Effectively isolate external environment's high temperature radiation, the inside electric elements of protection is not influenced by high temperature and is damaged, and the device can continue to work in the fire hazard environment.

The special flame-retardant net 61 is used for the inlet and the outlet of the air duct 62 to reduce the influence of external animals and flames on the sensor module group. The operation of the fan 6 generates a negative pressure in the air duct 62 to draw the outside air for detection. To a certain extent, protect the internal electrical components from damage due to high temperatures

The power pack module 9 is placed in a large amount of insulating oil 83 in the flame-retardant device shell 8, and a large-capacity battery pack is adopted, so that the device can continuously work for 1-2 hours. And a charging port 91 of the power supply module 9 is reserved on the device shell 8, so that the energy of the internal power supply is sufficient.

When a fire disaster happens, the color alarm lamp 5 sends a red flashing signal. When the fire condition of the environment changes from a light degree to a serious degree, the color of the colored warning lamp also changes differently. Specifically, the channel node alarm lamp in a lighter fire state is green. The heavier channel node alarm lamp is yellow orange, and the serious channel node alarm lamp is red and normally on.

Specifically, when a fire disaster occurs, the equipment placed in each channel node detects fire information in real time, and at least two of temperature, smoke and carbon monoxide data collected by the node equipment close to the fire center exceed a preset safety threshold. People are in the environment within a short time, and can lose mobility, thus being trapped in a fire scene and being incapable of self-rescue. Therefore, the node is judged to be a node with serious fire, and the alarm lamp 5 is red and normally on. Node devices slightly away from the fire center collect data that at most one exceeds the safety threshold, but other values also exceed normal values for a long time. People are in the environment for a short time without losing mobility and need to be guided into a region with lighter fire for waiting for rescue or leaving the scene. Therefore, the node is judged to be a node with a serious fire condition, and the alarm lamp 5 flashes in yellow and orange. The collected data of the node equipment far away from the fire center does not exceed the safety threshold value but exceeds the normal value for a long time. Therefore, the node 5 is judged to be a node with a serious fire condition, and the alarm lamp flashes in green.

The data acquisition device is relatively isolated from the external environment by adopting the fireproof heat-insulating material, so that the protection device cannot lose efficacy in a fire environment. Meanwhile, the fan in the air duct is opened to control sampling of external environment gas, the sensor module in the air duct processes the sampling gas, and the processor in the fireproof heat-insulating material sends data of the sensor to a fire control center containing the BIM module through the wireless processing module. Through the analysis to gathering the condition of a fire data, output some different colours light guide.
