Under the multiple effects of natural and human factors, occasional fires will pose a greater threat to the safety of large-scale complex venues. In order to avoid the occurrence of fires, or to minimize property losses and casualties after a fire occurs, the fire protection system plays a vital role in ensuring the safe operation of large venues. The fire protection system generally includes various sensors and fire protection equipment, in which sensors are used to detect some parameters in the environment, such as temperature, smoke concentration, etc. Fire protection equipment is used to implement fire protection measures such as fire extinguishing in an automatic or manual manner.

[0011] The present invention also provides a large-scale complex building intelligent fire monitoring and control method with multiple detection modes, which adopts a large-scale complex building intelligent fire monitoring and control system with multiple detection modes, comprising the following steps: Step 1: Conduct fire monitoring operations on large complex buildings; Use the detectors in the fire detection unit to monitor the fire situation in each fire zone; The smoke detector collects the smoke concentration signal 1 in the area in real time and sends it to the fire alarm controller. The fire alarm controller obtains the smoke concentration data 1 according to the smoke concentration signal 1 and compares the smoke concentration data 1 with the smoke concentration threshold. When the smoke concentration data 1 is greater than the smoke concentration threshold, the fire alarm controller controls all the sound and light alarm display devices and the fire sound and light alarm to give an alarm, and at the same time, sends a fire warning signal to the fire linkage controller; The temperature signal 1 of the area is collected in real time through the temperature sensor and sent to the fire alarm controller. The fire alarm controller obtains temperature data 1 according to the temperature signal 1 and compares the temperature data 1 with the temperature threshold. When the temperature data 1 is greater than the temperature threshold, the fire alarm controller controls all sound and light alarm display devices and fire sound and light alarms to give warnings, and at the same time, sends a fire warning signal to the fire linkage controller; The linear beam smoke detector collects smoke concentration signal 2 in the area in real time and sends it to the fire alarm controller. The fire alarm controller obtains smoke concentration data 2 according to smoke concentration signal 2 and compares the smoke concentration data 2 with the smoke concentration threshold. When the smoke concentration data 2 is greater than the smoke concentration threshold, the fire alarm controller controls all sound and light alarm display devices and fire sound and light alarms to give warnings, and at the same time, sends a fire warning signal to the fire linkage controller. The image data of the area is collected in real time through the image-type fire alarm detector and sent to the fire alarm controller, which processes the image data and identifies the fire based on the image recognition technology. After identifying the fire condition, it controls all the sound and light alarm display devices and the fire sound and light alarm to give warnings, and at the same time, sends a fire warning signal to the fire linkage controller; The temperature signal 2 and the smoke concentration signal 3 of the area are collected in real time through the temperature-smoke combination detector, and sent to the fire alarm controller. The fire alarm controller obtains temperature data 2 according to the temperature signal 2, obtains smoke concentration data 3 according to the smoke concentration signal 3, and compares the temperature data 2 with the temperature threshold, and compares the smoke concentration data 2 with the smoke concentration threshold. When the temperature data 2 is greater than the temperature threshold or when the smoke concentration data 2 is greater than the smoke concentration threshold, the fire alarm controller controls all sound and light alarm display devices and fire sound and light alarms to give warnings, and at the same time, sends a fire warning signal to the fire linkage controller; Use the cameras in each fire zone to collect image data in each monitoring area and each elevator in real time, and send it to the fire linkage controller; Step 2: Fire extinguishing operations on large complex buildings; After receiving the fire warning signal, the fire linkage controller sends the real-time image data of the monitoring area in the fire zone where the fire signal is located and the elevator to the display for real-time display, so as to monitor the fire scene and the situation in the elevator in real time; When the fire linkage controller receives the fire hydrant start signal, the fire linkage controller controls the water outlet solenoid valve to open, so as to use the water outlet main pipe to output water for fire extinguishing operations; When the fire linkage controller receives two fire warning signals in the same fire zone within the set time, or when the fire linkage controller receives a fire warning signal in the same fire zone and a manual alarm signal issued by the manual alarm button within the set time, the following actions are performed: The fire linkage controller controls the operation of the fire-related telephone switchboard, automatically makes calls to the fire telephone extensions in each fire zone, and automatically broadcasts the fire warning voice information and evacuation instruction voice information after someone answers the call; At the same time, the fire linkage controller controls the action of the fire emergency broadcast control device, and uses the fire emergency broadcast control device to control the emergency broadcast equipment in each fire zone to automatically broadcast the fire warning voice information and evacuation instruction voice information; At the same time, the fire linkage controller controls the action of the fire emergency lighting and evacuation indication system control device to control the activation of the emergency lighting equipment and evacuation indication equipment in each fire zone; At the same time, the fire linkage controller sends a signal to cut off the non-fire power supply to the fire power supply monitor, and uses the fire power supply monitor to cut off the main switch of the non-fire power supply in the fire area and related areas; At the same time, the fire linkage controller controls the elevator in the fire zone to stop at the first floor, and collects the elevator operation data in real time through the elevator monitoring sensor group, and then sends it to the display for real-time display; At the same time, the fire linkage controller controls the fire curtain in the fire zone to descend to 1.8m above the floor surface, and collects the position of the curtain in real time through the curtain monitoring sensor group, and then sends it to the display for real-time display; At the same time, the fire linkage controller controls the opening of the electric fence in the evacuation area to ensure smooth passage in the evacuation area, controls the opening of the electric barrier at the parking lot entrance and exit to ensure smooth passage in the parking lot entrance and exit, and controls the opening of the electric door in the evacuation area at the entrance and exit of the evacuation area to ensure smooth passage in the entrance and exit of the evacuation area; At the same time, the fire linkage controller controls the water outlet solenoid valve in the fire zone to open, so as to use the water outlet main pipe to output water for fire extinguishing operations. In this process, the low-pressure signal is collected through the low-pressure pressure switch, and the flow signal or pressure signal is collected through the flow sensor or pressure alarm valve. When the flow rate of the water outlet main pipe is less than the flow threshold or the pressure of the water outlet main pipe is less than the set threshold, the fire hydrant pump is controlled to start, so as to replenish water to the fire water pool and water tank; At the same time, the fire linkage controller controls the action of the pre-action valve subsystem in the fire zone where it is located, connects the sprinkler fire pump in the wet system to the injection pipe network, so as to use the injection pipe network for fire extinguishing operations, and collects the power supply and operation status of the sprinkler fire pump through the fire pump monitoring sensor group, and then sends it to the display for real-time display. Synchronously, the fire linkage controller controls the opening of the rain valve group to use the wet system to extinguish the fire by spraying. Synchronously, the fire linkage controller controls the opening of the water cannon solenoid valve and controls the start-up of the water cannon booster pump to use the water cannon outlet pipeline for fire extinguishing operations; At the same time, the fire linkage controller controls the opening of the air supply door in the places where pressurized air supply is required, and controls the start of the pressurized air supply fan to carry out air supply operations in the places where pressurized air supply is required. Synchronously, the fire linkage controller controls the lowering of the electric smoke barrier wall, the opening of the electric smoke exhaust window, the opening of the smoke exhaust door, and the start of the smoke exhaust fan to carry out smoke barrier and smoke exhaust operations in the predetermined area; At the same time, the fire linkage controller controls the ventilation and air conditioning systems in the smoke-proof partition to stop working, and closes the electric fire dampers in the smoke-proof partition. At the same time, it receives the action signal of the electric fire dampers and sends it to the display for real-time display; At the same time, the fire linkage controller sends a start signal to the gas fire extinguishing system to control the gas fire extinguishing device in the fire zone to start and perform fire extinguishing operations; At the same time, the fire linkage controller controls the evacuation passage fire door where the fire partition is located to close, and collects the opening signal, closing signal and fault status signal of the evacuation passage fire door through the fire door monitoring sensor and sends it to the fire door monitor; Step 3: System reset; When the fire source is extinguished, the fire linkage controller does not receive any alarm signal. The fire linkage controller sends a reset signal to each device in the fire execution unit to realize the reset action of the intelligent control system for fire protection in large-scale comprehensive buildings.

[0012] As a preference, in step one, the smoke concentration threshold is 5%OBS / M to 15%OBS / M.

[0013] As a preference, in step one, the temperature threshold is 60-90°C.
