Abstract

A natural gas leak warning system and method used in a city. The method comprises: a natural gas leak warning platform (101) sending, by means of the Internet of Things (IoT), when a natural gas leak has occurred inside a certain residential building at the city where the natural gas leak warning platform is located, to a vehicle monitoring platform (102) position information and name of the residential building where the natural gas leak has occurred and the name of the street surrounding the residential building where the natural gas leak has occurred; and the vehicle monitoring platform sending, by means of the IoT, when it is determined that there is a target vehicle (103) in the street that the name of the street belongs to, to the target vehicle natural gas leak warning information comprising the position information and the building name of the residential building where the natural gas leak has occurred. Said system enables the outside world to be notified, in a timely manner, that natural gas leak has occurred inside a certain residential building, preventing occurrence of severe safety accidents.

Abstract

An electrical fire warning system and method applied to a city, comprising: when a fire risk exists in a high-rise building of a city where an electrical fire warning platform (101) is located, the electrical fire warning platform may send position information and the name of the high-rise building having the fire risk, as well as the names of streets surrounding the high-rise building having the fire risk, to a vehicle monitoring platform (102) by means of an Internet of Things; and when determining that a target vehicle (103) is located on a street to which the street names belong, the vehicle monitoring platform sends fire warning information comprising the position information and name of the high-rise building having the fire risk to the target vehicle by means of the Internet of Things. With the system and the method, those elsewhere may know in time that a high-rise building has a fire risk, thereby preventing great economic losses.

Abstract

Building display screen-based system and method for natural gas leakage alarm. The system is characterized in that: when a natural gas leakage occurs in a residential building of a city, a natural gas leakage monitoring platform (101) calculates the straight line distances between location information of buildings in which building display screens registered in the city are located and location information of the residential building in which the natural gas leakage occurs and, when a target building display screen (102) of which the straight line distance from the location information of the residential building in which the natural gas leakage occurs is less than a specified threshold is determined and the target building display screen (102) is in a working state, transmits to the target building display screen (102) via the Internet of Things natural gas leakage alarm information comprising the location information and the building name of the residential building in which the natural leakage occurs; and the target building display screen (102) outputs the natural gas leakage alarm information. This allows the outside world to learn in a timely manner that a natural gas leakage occurs in a residential building, thus preventing a severe safety incident from being caused.

Abstract

A big data-based natural gas leak warning system and method, characterized in that: a natural gas leak warning platform acquires a natural gas detection concentration of the inner part of each residential building registered in a city, the natural gas detection concentration being reported by means of an Internet of Things; for each residential building, when determining that a natural gas leak occurs in an elevator of the residential building according to the natural gas detection concentration of the residential building, the natural gas leak warning platform calculates a straight-line distance between position information of each speaker device registered in the city and the position information of the residential building; and when determining that a target speaker device whose straight-line distance to the position information of the residential building is smaller than a specified threshold exists among all of the speaker devices, the platform sends natural gas leak warning speech comprising the position information and building name of the residential building to the target speaker device for playback by means of the Internet of Things. Thus, a natural gas leak occurring inside of a residential building may be known by those elsewhere in time, thereby preventing serious safety accidents.

Abstract

A natural gas leak warning system and method using an outdoor display screen (103), the system being characterized in that: when a natural gas leak occurs inside a residential building in a city in which a natural gas leak warning platform (101) resides, the natural gas leak warning platform may send the position information and the building name of the residential building in which the natural gas leak occurs and the names of streets around the residential building in which the natural gas leak occurs to an outdoor display screen monitoring platform (102) by means of an Internet of Things; when the outdoor display screen monitoring platform (102) determines that there is a target outdoor display screen (103) in a working state on a street to which the street names belong, the platform sends natural gas leak warning information comprising the position information and the building name of the residential building in which the natural gas leak occurs to the target outdoor display screen (103) by means of the Internet of Things; and the target outdoor display screen (103) outputs the natural gas leak warning information. By means of said system and method, a natural gas leak occurring inside of a residential building may be known by those elsewhere in time, thereby preventing a serious safety accident.

Abstract

A system and method for detecting a natural gas leak in a residential building. In the system, when a natural gas leak occurs inside of a residential building in a city, a natural gas leak detection platform sends the position information and building name of the residential building and names of streets around the residential building to an outdoor speaker monitoring platform by means of an Internet of Things; when the outdoor speaker monitoring platform determines that there is a target speaker device in a working state on a street to which the street names belong, the platform sends natural gas leak warning speech comprising the position information and building name of the residential building to the target speaker device by means of the Internet of Things, and the natural gas leak detection platform deducts a service fee directly proportional to the number of leaks from an electronic account bound to the residential building; and the target speaker device outputs the natural gas leak warning speech. Therefore, natural gas leak occurring inside of a residential building may be known by those elsewhere in time, thereby preventing serious safety accidents.

Abstract

A public safety mobile station-based system and method for natural gas leakage management: when a natural gas leakage occurs in a residential building of a city, a natural gas leakage monitoring platform (101) calculates the straight line distances between location information of public safety mobile stations registered in the city and location information of the residential building in which the natural gas leakage occurs and, when the presence of a target public safety mobile station (102) of which the straight line distance to the location information of the residential building in which the natural gas leakage occurs is determined, transmits to the target public safety mobile station (102) via the Internet of Things natural gas leakage alarm information comprising the location information and the building name of the residential building in which the natural gas leakage occurs; and the target public safety mobile station (102) outputs the natural gas leakage alarm information. The system allows the outside world to learn in a timely manner that a natural gas leakage occurs in a residential building, thus preventing a severe safety incident from being caused, and preventing major economic losses from being caused.
