Description
Technical Field
The invention relates to a fireproof smoke-proof high-viability communication base station.
Background
Emergency evacuation: in order to minimize casualties caused by fire, earthquake, riot attack and even military attack, emergency evacuation of people in a building is required as soon as possible when a disaster occurs. In large public buildings, especially high-rise or super high-rise public buildings, all elevators cannot be used for emergency evacuation when a fire disaster occurs, so that disaster-stricken personnel are very difficult to evacuate by walking in a disaster environment (such as dense smoke and dust diffusion), panic and misuse cannot be found out, or the situation that the exit is wrong, the direction of the misuse is wrong, the blind person is crowded, the local crowd steps on the elevator, and the like easily occurs, the emergency evacuation is blocked, and serious casualties are easily caused. Therefore, a positioning system is arranged in a building, the position of people in a room, the direction and the speed of people evacuation are monitored during emergency evacuation, and evacuation direction and position prompts are given to evacuated people according to monitoring results, so that evacuation guiding information and prompt are issued in time. For example, when an evacuee is in panic and is ready to use the elevator for evacuation (the fire control standard does not allow the elevator to be used for evacuation in the case of fire), the system can timely find the situation that the evacuee stays in the elevator hall for a long time, prompt the evacuee by means of fire control broadcasting, dialing a mobile phone, sending a miniature push, sending a short message and the like, and guide the evacuee to timely evacuate from other vertical evacuation channels (such as stairs) which are not corroded by the fire. For another example, fire rescue is based on the principle of rescuing people and then rescuing things, wherein one very important fire information is the positions, the numbers and the evacuation states of people in a building, and the positions, the numbers and the evacuation states can be obtained through 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, the 5G technology has the characteristics of large bandwidth, low delay, high stability and large number of equipment access permission, but is realized by means of an indoor 5G base station. According to the common use condition and the use position setting, the 5G base station is easy to generate communication blockage or delay when a large number of emergency evacuation prompt accesses, and the positioning accuracy and the timely release of the evacuation prompt are affected.
For example, normally, a certain evacuation port is covered by a micro base station a at other positions with a certain distance due to almost no personnel staying, when an emergency evacuation occurs, the personnel focus on the evacuation port with a bottleneck, at this time, the micro base station a cannot meet the communication requirement of the position, and the micro base station needs to be added at the position. In addition, at the vertical evacuation stair etc. position, because no one stays at ordinary times, the base station coverage can not be arranged generally, and services such as positioning can not be provided during emergency evacuation. And if the base stations are arranged according to emergency conditions at ordinary times, the miniature base stations in the emergency evacuation port and the stairs are easy to idle at ordinary times, and waste is caused. Particularly in super high-rise buildings, the number of building layers can reach tens or more than 100 layers, the number of the evacuation doors and other opening parts of each layer is generally more than 10, the height of stairs is hundreds of meters, the evacuation opening parts of the whole building are more, and if emergency communication base stations are arranged at all the evacuation openings, the required number of the base stations is larger.
In addition, the vertical evacuation time in the super high-rise building is long, the dense points of people change continuously in the vertical direction, and taking a Beijing super high-rise building as an example, 108 layers on the ground, the evacuation time from the top-layer going down stairs to the first layer can be more than 20 minutes for a normal person, and the dense evacuation crowd in the stairs decline gradually in about 20 minutes.
In addition, the 5G technology has the characteristics of low power consumption and densely arranged base stations, and the 5G miniature base station can realize self-contained storage batteries without an external power supply for short-term work.
Survival persistence capability of 5G micro base station: because the indoor micro base station generally adopts plastic products for preventing the signal shielding shell and is provided with ventilation and heat dissipation holes, the fireproof, heat-resistant and smoke-proof capacities of the indoor micro base station are poor, and once a fire disaster occurs, the indoor micro base station is rapidly destroyed if contacting with high-temperature smoke or flame, so that the capacity of providing 5G signal coverage is lost.
