[0057] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0058] In the process of realizing this application, the inventors found that firefighters face multiple risks in fire rescue work. These risks not only come from the fire itself, but may also include the on-site environment, material properties and other external factors. The high temperature environment generated by the fire is one of the most direct threats to firefighters. In some special environments, a large number of flammable and explosive items and dangerous chemicals release toxic gases. The smoke produced in the fire contains not only particulate matter, but may also contain various toxic chemicals, which can cause damage to the respiratory system, and the visibility is low in the smoke environment, which increases the difficulty of search and rescue work. In order to reduce these risks, it is very important to obtain internal rescue information when the operator's indoor base station stops working and personnel do not enter the disaster area.

[0059] In response to the above problems, an intelligent fire emergency method and system based on a system-level chip is provided in an embodiment of the present application, wherein the system-level chip is located at the emergency site; the method includes: after the system-level chip obtains the emergency instruction, the emergency 5G base station mode is turned on; the system-level chip establishes a first communication connection with the emergency system, and establishes a second communication connection with the user equipment at the emergency site; the system-level chip controls the emergency system through the first communication connection to give emergency instructions; the system-level chip provides emergency services to the user equipment through the second communication connection. In the method provided in the embodiment of the present application, when an emergency event occurs, the system-level chip can realize the emergency 5G base station function and perform emergency communications, thereby reducing personal injuries, reducing the probability of injury to fire rescue personnel, and improving rescue efficiency.

[0060] This embodiment provides a smart fire emergency method based on a system-level chip, which is implemented by a smart fire emergency system based on a system-level chip. Figure 1 As shown, the smart fire emergency system based on system-level chip includes: emergency system, 5G emergency base station, and command system.

[0061] Among them, the emergency system and 5G emergency base station are located at the emergency site.

[0062] The 5G emergency base station includes a system-level chip.

[0063] The 5G emergency base station establishes a first communication connection between the system-level chip and the emergency system, establishes a second communication connection between the system-level chip and the user equipment at the emergency site, and establishes a third communication connection between the system-level chip and the command system.

[0064] 1. Emergency system

[0065] It is an existing emergency system, such as one or more of the following: emergency broadcast system, emergency lighting system, and information collection system.

[0066] Among them, the emergency broadcast system is a broadcast system in the area (such as the broadcast system in the cinema, the broadcast system in the subway station, etc.). When there is no emergency event, the emergency broadcast system is an ordinary broadcast system used for normal broadcasting. For example, the emergency broadcast system stores daily broadcast content. In the daily working mode, the emergency broadcast system broadcasts according to the daily broadcast content (such as the broadcast system of the subway station broadcasts vehicles entering and leaving the station, etc.). When an emergency event occurs, the emergency broadcast system can receive the control command of the 5G emergency base station through the first communication connection, and perform emergency broadcasting based on the control of the 5G emergency base station. For example, when a fire occurs in the subway station, the broadcast system of the subway station receives the control command of the 5G emergency base station through the first communication connection, and then performs real-time emergency evacuation information broadcasting, escape route broadcasting, personnel search broadcasting, etc. based on the control of the 5G emergency base station.

[0067] Emergency lighting systems, such as lighting systems in a region (such as lighting systems in movie theaters, lighting systems in subway stations, etc.), are ordinary lighting systems used for normal lighting when no emergency event occurs. For example, the lighting system in a subway station illuminates the waiting area and the safety indication channel, etc. When an emergency event occurs, the emergency lighting system can receive control instructions from the 5G emergency base station through the first communication connection, and perform emergency lighting based on the control of the 5G emergency base station. For example, when a fire occurs in the subway station, the broadcasting system of the subway station receives control instructions from the 5G emergency base station through the first communication connection, and then turns on the emergency lighting mode based on the control of the 5G emergency base station, performs high-intensity lighting and flashing, improves the recognition of positioning points, etc., so as to provide people in the emergency area with light instructions for escape routes or other light instructions.

[0068] The information collection system includes multiple data collection devices, such as temperature collection devices, smoke collection devices, humidity collection devices, image collection devices, etc. When no emergency event occurs, the information collection system is an ordinary information collection system for temperature collection, smoke concentration collection, humidity collection, image collection, etc. When an emergency event occurs, the information collection system can receive the control instruction of the 5G emergency base station through the first communication connection, and perform emergency data collection based on the control of the 5G emergency base station. For example, when a fire occurs in the subway station, the information collection system of the subway station receives the control instruction of the 5G emergency base station through the first communication connection, and then performs real-time image collection, smoke concentration collection, temperature collection, humidity collection, etc. of the fire area based on the control of the 5G emergency base station. After the emergency event occurs, all data collected by the information collection system will be fed back to the 5G emergency base station through the first communication connection, and the 5G emergency base station will perform intelligent processing on the data and / or send the 5G data to the command system through the third communication connection, so that the command system can obtain real-time data of the emergency site in real time, helping the command system to perform intelligent processing and display, etc.

[0069] 2. Command system

[0070] The command system is an existing command system. For example, when an emergency occurs, emergency instructions and scanning instructions are sent to the 5G emergency base station through the third communication connection with the 5G emergency base station. At the same time, the on-site information fed back by the 5G emergency base station will be received through the third communication connection. For example, the 5G emergency base station scans the user equipment through the second communication connection based on the scanning instruction, and then the scanning results are fed back through the third communication connection. The command system will also make decisions, carry out emergency control and command, and display emergency situations based on the facts of the emergency.

[0071] 3. 5G emergency base station

[0072] The 5G emergency base station includes a system-on-chip (SoC). The system-on-chip can be a system-on-chip based on a low-cost / low-power / full-stack (L1 / L2 / L3) solution. Figure 2 As shown, the system-level chip has built-in NPU (Neural Network Processing Unit) core, DSP (Digital Signal Processor) core, shared memory, TMAC port, GMAC port. In addition, other modules can be built-in, which are not listed here one by one.

[0073] The 5G emergency base station can be used as an operator communication base station in the event of an emergency.

[0074] 1)NPU core

[0075] NPU core is used to provide hardware acceleration for the efficient execution of AI (Artificial Intelligence) algorithms.

[0076] The NPU cores are divided into two clusters of eight.

[0077] The 5G protocol stack is also deployed on the NPU core. Figure 2 In the example, the 5G protocol stack is deployed on NPU cluster1.

[0078] The DSP core also implements the 5G physical layer.

[0079] NPU cores use inter-core communication.

[0080] 2) DSP core

[0081] DSP core, used for digital processing, deployment of 5G physical layer, etc.

[0082] There are multiple DSP cores.

[0083] DSP cores use inter-core communication.

[0084] The NPU core and the DSP core communicate with each other through the FAPI (Front Haul Access Point Interface) interface. The unified interface between the NPU core and the DSP core can reduce the conversion time.

[0085] 3) TMAC port

[0086] The TMAC (Target Media Access Control) port establishes a third communication connection with the command system. The third communication connection is used to communicate with the command system and obtain information and instructions issued by the command system. In addition, the third communication connection is also used for the 5G emergency base station to transmit data to the command system.

[0087] Among them, the information and instructions issued by the command system are stored in the shared memory.

[0088] In specific applications, the information and instructions sent by the command system are recognized by the 5G protocol stack through the TMAC port and then placed in the shared memory.

[0089] 4) GMAC port

[0090] The GMAC (Gigabit Media Access Control) port establishes a first communication connection with the emergency system.

[0091] The first communication connection is used to communicate with the emergency system so as to control the emergency system. In addition, the first communication connection is also used to receive data sent by the emergency system.

[0092] The received data sent by the emergency system are stored in the shared memory.

[0093] 5) Shared Memory

[0094] Shared memory such as Figure 2 The SM (Shared Memory) in the chip is used to store information and instructions issued by the command system, data sent by the emergency system, and other data of the system-level chip.

[0095] That is to say, the shared memory SM can realize information interaction within the system-level chip and information interaction between the system-level chip and the outside.

[0096] In addition, inter-core communication is used within the chip.

[0097] The chip completes data transmission through the internal bus interface, without the need for additional docking equipment, such as switches, routers, etc. The interface is stable, and various docking problems caused by network connection will not occur at the emergency site.

[0098] The 5G emergency base station provided in this embodiment can provide 5G network based on the powerful computing power and kernel resources of the system-level chip. When an emergency occurs, it can also realize related functions (such as controlling the emergency system, etc.) and computing power processing. The functions of each module are transmitted through different high-speed buses to solve the problem of communication between modules. The system-level chip involved in this embodiment is small in size, light in weight, and works as soon as it is turned on. It abandons the traditional multi-device solution and has the characteristics of low cost and simple maintenance.

[0099] In addition, in the specific implementation, the 5G emergency base station can be a separate device or located in other devices. For example, the 5G emergency base station is deployed as a separate device in the emergency area. For another example, the 5G emergency base station is deployed in the lighting lamp in the lighting system, so that no separate equipment is added in the emergency area, and it is also more beautiful. The lighting lamp is a lighting lamp when there is no emergency event, and it is both a lighting lamp and a 5G base station when an emergency event occurs. For example, the emergency lighting system has built-in 5G emergency base station functions in addition to conventional emergency lights. It is used as an emergency light at ordinary times and as a 5G emergency base station in an emergency, which can ensure the normal communication of trapped people in the event of damage to the operator's base station.

[0100] The smart fire emergency system based on the system-level chip is in normal working mode when no emergency event occurs, such as providing ordinary broadcasting functions and emergency lighting functions. In the event of an emergency, it automatically switches to emergency mode, turns on the 5G emergency base station function for emergency communication, and urgently turns on the smart broadcast function through the 5G emergency base station to inform the trapped personnel of the escape information and route. After the personnel are evacuated, the trapped personnel scanning function based on the mobile phone IMSI information can also be used to complete the confirmation of the trapped personnel information, thereby reducing the risk of personnel damage, reducing the probability of injury to fire rescue personnel, and improving the purpose of rescue efficiency. At the same time, always maintain communication connection with the background command system to ensure that the emergency scene (such as the fire scene) information can reach the command system as soon as possible.

[0101] In the specific implementation, the system-level chip (such as Figure 2 The system-level chip shown in the figure is located at the emergency site and is used to execute the steps executed by the system-level chip in the smart fire emergency method based on the system-level chip provided in this embodiment. Figure 3 The implementation process of the smart fire emergency method based on system-level chip provided in this embodiment is as follows:

[0102] 301. After receiving the emergency command, the system-level chip starts the emergency 5G base station mode.

[0103] For example, after the system-level chip obtains the emergency command issued by the command system through the third communication connection, it switches to the emergency 5G base station mode, so that the 5G emergency base station where the system-level chip is located maintains normal communication with the operator's computer room, and the 5G base station is turned on normally.

[0104] The third communication connection is a communication connection between the system-on-chip and the command system. For example, the system-on-chip establishes the third communication connection with the command system through the TMAC port.

[0105] The third communication connection is used to communicate with the command system to obtain information and instructions issued by the command system. In addition, the third communication connection is also used for the 5G emergency base station to transmit data to the command system.

[0106] 302. The system-on-chip establishes a first communication connection with the emergency system, and establishes a second communication connection with a user device at the emergency site.

[0107] For example, a first communication connection is established with the emergency system through the GMAC port.

[0108] The first communication connection is used to communicate with the emergency system so as to control the emergency system. In addition, the first communication connection is also used to receive data sent by the emergency system.

[0109] A second communication connection is established between the 5G communication capability of the 5G emergency base station where the system-level chip is located and the user equipment at the emergency site.

[0110] The second communication connection is used to provide communication services for the user equipment.

[0111] In addition, the user equipment is a device with 5G communication capability, such as a mobile phone, a tablet, a computer, etc. For example, the mobile phone of the trapped person can access the 5G emergency base station through the second communication connection for communication.

[0112] In addition, after establishing the second communication connection, if the system-level chip obtains the scanning instruction issued by the command system through the third communication connection, it turns on the 5G emergency base station emergency scanning function, scans the user equipment through the second communication connection, and feeds back the scanning results to the command system through the third communication connection.

[0113] For example, the system-level chip scans the IMSI information of the user equipment through the second communication connection to scan the trapped person and complete the confirmation of the trapped person information.

[0114] 303. The system-level chip controls the emergency system to give an emergency instruction through the first communication connection.

[0115] For example, the system-level chip controls the emergency broadcast system to broadcast real-time emergency evacuation information through the first communication connection. And / or, the system-level chip controls the emergency lighting system to turn on the emergency lighting mode through the first communication connection, and performs high-intensity lighting and flashing to improve the recognition of the positioning point.

[0116] For example, the system-level chip controls the emergency broadcast system to perform intelligent broadcasting functions through the first communication connection, and performs real-time emergency evacuation broadcasting. For example, the command system sends the emergency evacuation broadcasting content to the system-level chip, and then the system-level chip sends it to the emergency broadcast system to broadcast real-time emergency evacuation information (such as informing trapped people of escape information and routes, etc.). The system-level chip controls the emergency lighting system to perform intelligent lighting functions through the first communication connection, and performs real-time emergency evacuation lighting. For example, the command system sends relevant information such as emergency evacuation lighting to the system-level chip, and then the system-level chip sends it to the emergency lighting system, thereby turning on the emergency lighting mode, providing high-intensity lighting and flashing functions, and improving the positioning point identification.

[0117] In addition, if the system-level chip performs a user equipment scan, the system-level chip can also control the emergency system through the first communication connection to perform a personnel search broadcast based on the scan result.

[0118] 304. The system-on-chip provides an emergency service to the user equipment through the second communication connection.

[0119] Among them, the emergency service is an existing service, such as the system-level chip sending an escape route to the user equipment through the second communication connection, providing emergency communication for the user equipment, etc.

[0120] The system-on-chip in the system-on-chip based smart fire emergency method provided in this embodiment is a system-on-chip based on a low-cost / low-power / full-stack (L1 / L2 / L3) solution.

[0121] The system-on-chip based smart fire emergency method provided in this embodiment can be a multifunctional fire emergency base station implemented based on the system-on-chip.

[0122] The smart fire emergency method based on system-level chip provided in this embodiment can integrate basic emergency lighting functions, emergency 5G base station functions (such as emergency communication functions) implemented based on system-level chips, intelligent broadcast functions, personnel scanning functions, and video functions. When an emergency event occurs, it automatically switches to emergency mode, and the system-level chip turns on the 5G emergency base station function for emergency communication. The intelligent broadcast function is urgently turned on through the 5G emergency base station to inform the trapped personnel of the escape information and route. After the personnel are evacuated, the trapped personnel scanning function based on the mobile phone IMSI information can also be used to complete the confirmation of the trapped personnel information, thereby reducing personnel injuries, reducing the probability of injury to fire rescue personnel, and improving the purpose of rescue efficiency.

[0123] At the same time, always maintain communication connection with the background command system to ensure that information from the emergency scene (such as the fire scene) can reach the command system as soon as possible.

[0124] See below Figure 4 , the implementation process of the smart fire emergency system based on a system-level chip provided in this embodiment when executing the smart fire emergency method based on a system-level chip is described again:

[0125] Daily working mode: The emergency system is used as a normal emergency system. For example, the emergency broadcast system stores daily broadcast content. In the daily working mode, the emergency broadcast system broadcasts according to the daily broadcast content. The emergency lighting system is used for normal lighting.

[0126] When an emergency occurs, the command system issues emergency instructions through the third communication connection, and the system-level chip switches to the emergency 5G base station mode. The 5G emergency base station where the system-level chip is located maintains normal communication with the operator's computer room. The 5G base station is turned on normally, and the trapped people's mobile phones can access the 5G emergency base station for communication.

[0127] When an emergency occurs, real-time emergency evacuation broadcasting can be carried out, such as the command system sends the emergency evacuation broadcasting content to the system-level chip, and then the system-level chip sends it to the emergency broadcasting system for real-time emergency evacuation information broadcasting. Real-time emergency evacuation lighting can also be carried out, such as the command system sends the emergency evacuation lighting and other related information to the system-level chip, and then the system-level chip sends it to the emergency lighting system, thereby turning on the emergency lighting mode, providing high-intensity lighting and flashing functions, and improving the positioning point setting accuracy.

[0128] If the command system issues a scanning command through the third communication connection, thereby turning on the emergency scanning function of the 5G emergency base station, the 5G emergency base station where the unified chip is located scans the user equipment through the second communication connection, and feeds back the scanning result to the command system through the third communication connection. At the same time, the scanning result is sent to the emergency broadcast system through the first communication connection, and then the emergency system is controlled through the first communication connection to perform personnel search and broadcast based on the scanning result.

[0129] In addition, the information of trapped persons can also be displayed on the command system, and the command center personnel complete the task deployment and arrange rescue personnel to conduct search and rescue.

[0130] The system-on-chip-based smart fire emergency method provided in this embodiment will automatically complete the conversion from ordinary functions to 5G emergency base stations in emergency situations, ensuring normal communication for trapped persons when the operator's base station is damaged, and conducting real-time emergency evacuation broadcasts and information transmission for background rescue personnel through background instructions, while completing scanning and confirmation of trapped persons, shortening the search time for rescue personnel, ensuring that the background command center is aware of the information of trapped persons on the scene as soon as possible, and reducing the search and rescue workload and personal safety of firefighters.

In the method provided in this embodiment, when an emergency event occurs, the system-level chip can realize the emergency 5G base station function and perform emergency communication, thereby reducing the risk of personal injury, reducing the probability of injury to fire rescue personnel, and improving rescue efficiency.

[0132] In an optional embodiment of the present application, the system-level chip providing emergency services to the user equipment through the second communication connection may include but is not limited to restarting the system-level chip through a system startup device, wherein the system startup device includes at least multiple system partitions, each system partition is configured with a system file, and the startup process includes at least:
