Unless otherwise specified, the "connection" and "coupling" in this paper include direct and indirect connection (coupling).

[0048] The technical solutions provided by the embodiments of the application will be described in detail below with reference to the drawings.

[0049] The method in the specification is based on a linkage air purification system, which can integrate and manage resources in a building. The building includes several rooms, and each room shares the linkage air purification system. The linkage air purification system includes a cascaded fresh air system, a fire fighting system and a total control device. The fresh air system is used for air conditioning of each room, for example, the fresh air system can be a central air conditioner in the related art. The fire fighting system can at least be used for monitoring and alarming fire fighting problems, for example, the fire fighting system can be a fire alarm system in the related art. In the absence of a fire, the fresh air system and the fire fighting system can perform their respective functions to meet the individual needs of users. The total control device is used to control the fresh air system and the fire fighting system to prevent disaster spread in the event of a fire. The total control device is connected with the fresh air device, and the total control device is also connected with the fire fighting system.

[0050] The fresh air system in the specification comprises: fresh air devices respectively arranged in a plurality of rooms, and air channels respectively communicated with the plurality of fresh air devices. The fresh air device is used to control the on-off between the room and the air channel, and control the direction of the air flow (the fresh air device can control the air flow from the air channel to the room, or control the air flow from the room to the air channel). The air channel is used to transport air, and the air channel comprises an air outlet communicated with the external environment. Under the control of the fresh air device, the air flow can flow from the room to the environment, or flow from the environment to the room. In daily use, the fresh air device can be used as an air conditioner, at this time, the air flow in the air channel can be low in temperature.

[0051] The fire-fighting system in the specification comprises: light sensing modules respectively arranged in the plurality of rooms, smoke first modules, smoke second modules arranged in air channels between any two of the rooms, and temperature detection modules distributedly arranged in the air channels. The light sensing module and the smoke first module are mainly used to determine whether a fire occurs in the room. The smoke second module and the temperature detection module are mainly used to monitor the spread of the fire. In an optional embodiment of the specification, the sensitivity of the smoke second module is higher than the sensitivity of the smoke first detection module.

[0052] The method in the specification is executed by the general control device. Now the method in the specification will be described. The method in the specification comprises the following steps:

[0053] S100: In the case that the fire-fighting system determines that a fire occurs in at least one of the plurality of rooms, the room where the fire occurs is determined as a first target room based on the data detected by the fire-fighting system.

[0054] In an optional embodiment of the specification, the determination of the fire can be based on the data collected by the light sensing module and / or the data collected by the smoke first module; in another optional embodiment of the specification, the fire-fighting system further comprises an interactive module arranged in the room, and a user can determine whether a fire occurs based on subjective judgment, and if the user determines that a fire occurs, the user can inform the fire-fighting system that a fire occurs through interaction with the interactive module.

[0055] In addition, in an optional embodiment of the specification, whether a fire occurs can be determined by the fire-fighting system; in another optional embodiment of the specification, the fire-fighting system can collect data and send the data to the general control device, and the general control device determines whether a fire occurs based on the data sent by the fire-fighting system.

[0056] The first target room determined in this step can be one or more than one.

[0057] S102: Control the fresh air equipment arranged in the first target room to draw air from the first target room, so that the drawn air flows through the air duct and is discharged to the air outlet; and close the fresh air equipment of other rooms except the first target room, so that the other rooms are not communicated with the air duct.

[0058] This step timely controls the fresh air equipment in the first target room to draw air from the first target room, which can eliminate the smoke in the first target room to a certain extent, improve the air condition in the first target room, provide escape conditions for personnel in the first target room, and reduce the risk of coma caused by excessive smoke inhalation of personnel.

[0059] In an optional embodiment of the present application, the condition for determining the occurrence of a fire is relatively strict. Specifically, the step of determining the occurrence of a fire is that if the data collected by the light sensing module and the smoke first module arranged in a room both indicate the presence of a fire, it is determined that a fire occurs in the room. Under this relatively strict condition, if a fire can be detected, the possibility of misjudgment is low, and at this time, the measures in this step should be taken in time to minimize the loss.

[0060] Since the linkage type air purification system is shared by multiple rooms, the fire and the smoke and high temperature caused by the fire may spread to other rooms. In order to avoid this situation, the present application also closes the fresh air equipment of other rooms except the first target room, so that the other rooms are not communicated with the air duct, so as to reduce the negative impact of the fire spreading to other rooms through the linkage type air purification system.

[0061] Generally, the air outlet is closed. If a fire is detected, the air outlet is opened to discharge the smoke to the environment.

[0062] S104: Receive the data collected by the smoke second module and the temperature detection module.

[0063] The smoke second module and the temperature detection module are both arranged in the air duct, and the spread of the fire can be monitored based on the data collected thereby.

[0064] In an optional embodiment of the present application, the smoke second module can be multiple, and the multiple smoke second modules can be distributed in the air duct. The temperature detection module can also be multiple, and the multiple temperature detection modules can also be distributed in the air duct.

[0065] S106: Determine the smoke second module that detects smoke as a smoke target module.

[0066] Generally, the fresh air system adjusts the air environment of the room by blowing air into the room, that is, the possibility of smoke spreading into the air duct is low. If the smoke second module can detect smoke in the air duct, it means that smoke has spread and the fire has a tendency to spread, and the current situation is worth attention.

[0067] Due to the different structures of buildings, sometimes the design of the building is even asymmetric, in order to reduce the time of air flow into the room and improve the air conditioning efficiency of the room, the air duct of the fresh air system is also designed according to the structure of the building, which makes the direction and distribution of the air duct complex. In addition, the first target room can be any one of several rooms, which makes it difficult to predict the spreading direction and path of smoke in the air duct. Through the design of the smoke target module, the tendency of smoke spreading can be detected.

[0068] S108: Control the fresh air equipment which is in communication with the position of the air duct where the smoke target module is located to extract air from the second target room where the fresh air equipment is arranged, so that the extracted air flows through the air duct and is discharged to the air outlet.

[0069] This step first determines the room connected to the smoke target module through the air duct as the second target room, and then controls the fresh air equipment arranged in the second target room to extract air from the second target room, so as to avoid the smoke in the air duct from spreading to the second target room. Since the position where the smoke target module is located has detected smoke, and the smoke target module is connected to the second target room through the air duct, the smoke may enter the second target room along the air duct, that is, the second target room is more likely to be affected by the fire than other rooms where the first target room is located. At this time, only closing the fresh air equipment of the second target room may not be able to avoid the spread of the disaster. Extracting air from the second target room can make the air in the second target room flow into the air duct through the fresh air equipment arranged in the second target room. At this time, even if the second target room has been affected by the fire and is full of smoke, the smoke in the second target room can be extracted to facilitate the escape of personnel in the second target room. It can also prevent the smoke in the air duct from spreading to the second target room.

[0070] Until this step, part of the fresh air equipment in the fresh air system is controlled to extract air, and part is controlled to be closed. Some of the fresh air equipment which is controlled to be closed in step S102 is controlled to extract air in this step.

[0071] In an optional embodiment of the present application, the fire-fighting system further comprises alarm devices arranged in the plurality of rooms respectively. The alarm device arranged in the second target room is controlled to issue an escape alarm.

[0072] S110: Determine the temperature detection module that detects the temperature abnormality as the temperature target module.

[0073] The temperature detection module can detect the temperature of the environment in which it is located, and can also determine whether the temperature of the environment in which it is located is rising too fast based on the temperature data it detects (if so, it is determined to be a temperature abnormality. In an optional embodiment, it can be determined whether the temperature is abnormal by determining whether the temperature is abnormal based on a temperature rise threshold.

[0074] Since the temperature detection module is distributed and arranged in the airway, not all temperature detection modules are temperature target modules. The temperature target module determined in this step can be one or more.

[0075] S112: Close the fresh air device in the room that is in communication with the location of the temperature target module via the airway, is within a first threshold distance from the temperature target module, is within a second threshold distance from the smoke target module, and is located between the temperature target module and the air outlet in the airway, so that the other room is not in communication with the airway.

[0076] This step aims to further control the fresh air system to control the spread of the disaster. The control means can be to adjust the state of the fresh air device that has been adjusted to exhaust to closed.

[0077] The function of the smoke detection module (including the smoke first module and the smoke second module) is to monitor the spread of the fire through the smoke. Smoke cannot penetrate walls and can only be considered from the perspective of gas flow. In addition to producing smoke, open flames also emit heat. The wall is not absolutely blocked by heat, so the temperature detection module can locate the fire point based on the change in temperature.

[0078] If a room is close to the fire point (within a first threshold distance from the temperature target module), smoke, sparks, etc. also have a way to enter the room (in communication with the location of the temperature target module via the airway), and there is a risk of smoke entering the room (within a second threshold distance from the smoke target module), the protective measures (such as exhaust) taken for the second target room may have a negative impact on the room (located between the temperature target module and the air outlet in the airway), the room should be isolated from the airway as much as possible, that is, the fresh air device in the room is closed. If the room was the second target room before, the state of the fresh air device needs to be adjusted from exhaust to closed.

[0079] The new air system and the fire-fighting system in the building are cascaded by the method in the specification, and the two systems are combined on the basis of their respective functions, and realize the fire-fighting control of the building to which they belong under the management of the total control device. Through the linkage type air purification system in the specification, the location of the fire can be effectively located, and measures are taken to avoid the spread of the fire to other rooms during the process of the fire. Moreover, through the method in the specification, the smoke generated by the combustion can be discharged to the outdoor on the basis of determining the location of the fire, which is beneficial to assist the personnel at the fire scene to escape and reduce the casualties.

[0080] In a further optional embodiment of the specification, the fire-fighting system further comprises a living body detection device, which is respectively arranged in the plurality of rooms. After determining the first target room, if the living body detection device arranged in the first target room detects that there is a living body in the first target room, the new air equipment arranged in the first target room is controlled to exhaust air from the first target room. To ensure that the personnel in the first target room can escape. But this will also make the smoke in the first target room pollute the gas in the airway, which may have a negative impact on other rooms. But compared with the safety of the personnel in the first target room, this operation is reasonable and can maximize the benefits.

[0081] If the living body detection device arranged in the first target room detects that there is no living body in the first target room, the new air equipment arranged in the first target room is controlled to be closed. To avoid the spread of the disaster as much as possible.

[0082] In a further optional embodiment of the present disclosure, the building is further provided with an escape passage. Each room is connected through the escape passage. Exemplarily, the escape passage can be a corridor of the building, or can be other passage available for pedestrians. In this embodiment, if the data collected by the smoke first module arranged in a room indicates that there is a fire, and the data collected by the photosensitive module arranged in the room indicates that there is no fire, it is indicated that the room cannot be determined to have a fire, which can be caused by smoking or burnt food, but it is also difficult to rule out the risk of fire. Therefore, the rooms other than the room are taken as third target rooms. If the fresh air equipment of the third target room is in an open state, it is indicated that there is a high probability of people in the third target room, and the fresh air equipment is opened by the people in the third target room. At this time, the fresh air equipment in the third target room is sending air to the third target room. Therefore, the output power of the fresh air equipment arranged in the third target room is reduced, instead of directly closing the fresh air equipment in the third target room, so as to avoid affecting the body feeling of the people in the third target room. If there is indeed an open fire but the sensor fails to detect it, the air in the third target room can also be ventilated to prevent the fire from spreading. The ventilation equipment in the escape passage is controlled to be opened. Because the fresh air equipment in the third target room is always sending air to the third target room, the air pressure in the third target room is higher than that in the escape passage. The air flows from the gap of the third target room into the escape passage. The opening of the ventilation equipment can discharge the smoke overflowed from the third target room.

[0083] In a further optional embodiment of the present disclosure, after the first target room is determined, the ventilation equipment is controlled to be opened to provide conditions for the escape of the people in the building.

[0084] In addition, after the first target room is determined, the data collected by the smoke first module arranged in the first target room and representing the smoke concentration is taken as first data. The data collected by the smoke first module arranged in the second target room and representing the smoke concentration is taken as second data. The first threshold distance is determined such that the first threshold distance is positively correlated with the difference between the first data and the second data, and is negatively correlated with the data collected by the temperature target module and representing the temperature.

[0085] The difference can indicate the diffusion of smoke, i.e. the diffusion of disaster caused by smoke. The first threshold distance is associated with the difference. The greater the difference, the less serious the spread of smoke is at the current time. At this time, the first threshold distance is appropriately increased, so as to identify the rooms in which the fresh air equipment needs to be closed from a plurality of other rooms. The second target room in the other rooms is still controlled to be ventilated by the fresh air equipment, so as to guarantee the escape of the people in the second target room.

[0086] The data characterizing the temperature can determine the temperature value, and the higher the temperature indicates that the fire spread is more serious. Even if the smoke spread is not very serious, enough vigilance should be raised.

[0087] In a further optional embodiment of the present specification, if a specified number of temperature detection modules are determined to be temperature target modules, indicating that the spread of the fire has been uncontrollable, all fresh air equipment is directly controlled to be closed, and the air outlet is controlled to be closed. At this time, the fire has been uncontrollable, and any adjustment of the air flow may exacerbate the fire. The value of the specified number is positively correlated with the temperature detected by the temperature detection module at the current time.

[0088] For the determination of the second threshold distance, in an optional embodiment of the present specification, if no living body is detected in the second target room, the second threshold distance is determined such that the second threshold distance is greater than the first threshold distance, and the second threshold distance is positively correlated with the smoke concentration of the gas discharged by the air outlet. In this embodiment, the air outlet is also provided with a smoke detection device. The smoke discharged by the air outlet may be the smoke generated in the first target room determined for the first time, or may contain the smoke generated in other rooms ignited by the spread of the fire.

[0089] Alternatively, if a living body is detected in the second target room, the second threshold distance is directly determined to be equal to the first threshold distance. This embodiment takes into account the situation in the second target room. If there is a user in the second target room, the safety of the user should be guaranteed as much as possible, and the isolation between the room and the air duct should be established as much as possible to ensure that as little smoke as possible enters the second target room.
