Description
Technical Field
the utility model relates to a high viability communication base station of fire prevention and smoke protection.
Background
Emergency evacuation: in order to reduce casualties of fire, earthquake, violent and terrorist attacks and even military attacks as much as possible, people in a building need to be evacuated as soon as possible when the disaster happens. In a large public building, particularly a high-rise or super high-rise public building, all elevators cannot be used for emergency evacuation when a fire disaster occurs, so that the difficulty of evacuation of disaster-stricken people by walking in a disaster environment (such as dense smoke and dust diffusion) is high, and the situations of scaring, incapability of finding an exit, or wrong exit, wrong direction, blind stepping from people to people and local crowds are easy to occur, so that the emergency evacuation is blocked, and serious casualties are easy to cause. Therefore, it is necessary to provide a positioning system in a building, monitor the indoor position, the evacuation direction and the evacuation speed of people during emergency evacuation, prompt the evacuation direction and the evacuation position of the people according to the monitoring result, and issue evacuation guidance information and prompt in time. For example, when an evacuation person is in panic and ready to evacuate by using an elevator (the fire-fighting specification does not allow evacuation by using the elevator in case of fire), the system timely finds the situation that the person stays in the elevator hall for a long time, and can prompt the person in the elevator hall in ways of fire-fighting broadcasting, dialing a mobile phone of the person, sending a micro push, sending a short message and the like to guide the person to evacuate from other vertical evacuation channels (such as stairs) which are not eroded by the fire in time. For another example, fire rescue is based on the principle of saving people first and then saving things, and one of the very important information about fire protection is the location, number and evacuation status of people in a building, which can be obtained by indoor positioning.
5G micro base station: the 5G technology is popularized and applied at home and abroad within a few years. In the 5G era, no matter indoor positioning or individual micro, short message pushing and dialing evacuation personnel mobile phones, although the 5G technology has the characteristics of large bandwidth, low delay, high stability and allowance of access of a large amount of equipment, the 5G technology needs to be realized by an indoor 5G base station. The 5G base station arranged according to the common use condition and the use position is easy to generate communication blockage or delay when a large amount of emergency evacuation prompt accesses, and the positioning precision and the prompt release of the evacuation prompt are influenced.
for example, in an evacuation port, almost no people stay at the evacuation port, the micro base station a is covered by the micro base station a at another position with a certain distance, and in emergency evacuation, people focus on the evacuation port with a "bottleneck", and at this time, the micro base station a cannot meet the communication requirement at the position, and the micro base station is required to be added at the position. In addition, at positions such as vertical evacuation stairs, due to the fact that no person stays at ordinary times, base station coverage cannot be arranged generally, and services such as positioning cannot be provided during emergency evacuation. And if carry out the basic station according to emergency situation and arrange at ordinary times, easily lead to emergent sparse oral area, the miniature basic station in the stair idle at ordinary times, lead to the waste. Particularly, in a super high-rise building, the number of building floors can reach tens of floors or more than 100 floors, the number of the evacuation door equal openings on each floor generally exceeds 10, the height of stairs is hundreds of meters, the number of the evacuation openings of the whole building is large, and if emergency communication base stations are arranged at each evacuation opening, the required number of the base stations is large.
In addition, the vertical evacuation time in the super high-rise building is very long, the dense points of people are continuously changed in the vertical direction, for example, in a super high-rise building in Beijing, 108 floors are arranged on the ground, the evacuation time from the top floor to the first floor is more than 20 minutes for the regular people, and the dense evacuation crowd in the stairs gradually descends within about 20 minutes.
In addition, the 5G technology has the characteristics of low power consumption and dense arrangement of base stations, and the 5G miniature base station can be provided with a storage battery and does not need an external power supply for short-term work.
Survival persistence of 5G micro base station: because the indoor micro base station generally adopts plastic products in order to prevent the signal shielding shell, and leaves the ventilation louvre, so the fire prevention of indoor micro base station, heat-resisting and smoke-proof ability all are relatively poor, in case meet with the conflagration, indoor micro base station if contact with high temperature flue gas or flame, can destroy rapidly to lose the ability that provides 5G signal coverage.
