[0026] Embodiment 1: Reference Figure 1-Figure 2 , is an embodiment of the present invention, and provides a fire emergency communication method, such as Figure 1 As shown, including: S100, obtaining communication requests initiated by each communication sub-terminal, determining state information of the communication terminal, and receiving communication requests of the communication sub-terminals through the communication terminal.

[0027] Preferably, obtaining the communication request initiated by each communication sub-terminal and determining the status information of the communication terminal includes: Identify and record the status information of the communication sub-end and the communication terminal in real time, including the idle state and the busy state; Monitor the communication request sent by the communication sub-terminal in real time, the communication terminal receives the communication request, and when the communication sub-terminal establishes a communication connection with the communication terminal, modify the current status of the communication sub-terminal and the communication terminal to a busy state, and when the communication sub-terminal disconnects the communication connection with the communication terminal, modify the current status of the communication sub-terminal and the communication terminal to an idle state; If a communication sub-end or a communication terminal fails, the state of the communication sub-end or the communication terminal is modified to a busy state; if the failure is removed, the state of the communication sub-end or the communication terminal is modified to an idle state; Multiple communication channels are set between each communication sub-end and the communication terminal, and a communication level is set for each communication channel.

[0028] Specifically, in this embodiment, a plurality of fire communication sub-terminals and communication terminals are included. The communication sub-terminals are configured in the actual use site, and the communication terminal is configured in the fire center, which may be a control center, a base station or other relay equipment, etc., wherein the actual use site may be a school, a shopping mall, an office building, a residential area and the like, and the communication request from each communication sub-terminal is continuously monitored, wherein the communication sub-terminal may be a portable mobile terminal or a fixed landline, etc., and the communication request may be an alarm communication signal or other important information. After the communication request is detected, the communication request is received and processed to ensure that no communication demand is missed. For each received request, the current working status of all available communication terminals is detected, and a status request packet may be directly sent to the terminal to obtain real-time status information, or the terminal status information may be determined based on the resource usage, or the device status identification or the device heartbeat signal may be used for determination; further, based on the queried status information, the communication terminal in the idle state is determined so as to allocate resources for the new communication request, and the status information of each communication terminal is recorded at the same time, and the status information includes but is not limited to whether it is idle, the reason for being busy, the expected recovery time, etc.

[0029] It should be noted that this step can respond quickly in emergency situations and reasonably allocate limited communication resources to ensure the efficiency and reliability of communication.

[0030] S200, if at least one of the communication terminals is currently in an idle state, then by selecting the communication channel set between the communication sub-terminal and the communication terminal, communication is established with the communication terminal in sequence according to the timing of the communication request initiated by the communication sub-terminal, and environmental data of the communication sub-terminal is obtained in real time.

[0031] Preferably, establishing communication with the communication terminal in sequence according to the timing of the communication request initiated by the communication sub-terminal includes: Based on the acquired communication request initiated by the communication sub-terminal and determining that at least one of the communication terminals is currently in an idle state, establishing a communication connection between the communication sub-terminal and the currently idle communication terminal; Through the communication channel set between the communication sub-terminal and the communication terminal, according to the communication level of the communication channel, a communication channel with the highest communication level is selected for connection, and according to the time sequence of the communication sub-terminal initiating the communication request, the communication sub-terminal is sequentially communicated with the currently idle communication terminal, and the environmental data around the communication sub-terminal is synchronously obtained; Environmental data includes the location information of the communication sub-terminal, environmental temperature and humidity information, and smoke concentration information.

[0032] Furthermore, the communication levels of the communication channel include: The communication level is calculated based on the bandwidth index, transmission index, and delay index of the communication channel, which is expressed as: ; in, represents the actual measured available bandwidth, represents the theoretical maximum bandwidth, Indicates the actual bandwidth utilization. Indicates the optimal bandwidth utilization determined by the network type. Indicates the average transmission rate actually measured, Indicates the expected transmission rate of the current communication channel. Indicates the number of bits that were erroneous during transmission. Indicates the total number of bits transmitted, Indicates the time when the return data packet is received. Indicates the time when the test data packet is sent. , , , , represents the weight coefficient, and , these weight coefficients can be adjusted according to different application scenarios and the importance of each indicator, among which, Indicates the maximum acceptable delay, which can be determined based on application requirements.

[0033] Specifically, the bandwidth index of the communication channel mainly considers the available bandwidth and bandwidth utilization of the communication, and calculates the ratio of the bandwidth occupied by the actual transmitted data to the total available bandwidth within a period of time. Generally speaking, a bandwidth utilization that is too high (close to 100% may cause congestion) or too low (indicates a waste of resources) indicates that there are problems with the communication quality, and a moderate bandwidth utilization (such as 30%) indicates that the communication quality is poor. -70%, depending on the network type and application requirements) indicates good communication quality; the transmission indicators of the communication channel mainly consider the average transmission rate and the bit error rate. The calculated average transmission rate is compared with the expected transmission rate of the communication channel. If it is close to or reaches the expected transmission rate, the communication quality is good. If it is far below expectations, the communication quality is poor. In addition, by sending known data sequences (such as specific test data frames) at both ends of the communication channel, the received data is compared with the sent data at the receiving end, and the number of erroneous bits and the total number of transmitted bits are counted. The lower the bit error rate, the higher the communication quality; the delay indicator of the communication channel mainly considers the delay rate. Use a tool to send a small test data packet to the other end of the communication channel and wait for it to return. The time from sending to receiving the return packet is recorded. A smaller round-trip delay indicates better communication quality, and a larger round-trip delay will affect the quality of communication with high real-time requirements.

[0034] It should be noted that the communication level of the communication channel comprehensively considers the impact of factors such as bandwidth, bandwidth utilization, transmission rate, bit error rate and delay on the quality of the communication channel. By adjusting the weight coefficient, it can adapt to the needs of different application scenarios. After obtaining the communication request from the communication sub-end, the communication channel with better transmission effect is selected for communication, ensuring better communication effects at both ends of the communication.

[0035] S300: If the communication terminals are currently in a busy state, queues are sorted according to the communication priorities of the communication sub-terminals, and communication connections are established between the communication sub-terminals and the communication terminals through the communication channels.

[0036] Preferably, sorting the queues according to the communication priorities of the communication sub-terminals, and establishing a communication connection between the communication sub-terminals and the communication terminal through the communication channel includes: Based on the communication requests of each communication sub-terminal obtained, and the communication terminals receiving the requests are all in a busy state, the communication priority of the current communication sub-terminal is calculated according to the location area, communication quality and communication urgency of the communication sub-terminal, and the communication request queue is generated according to the value of the communication priority. The communication request queue is updated regularly; Specifically, the location area of ​​the communication sub-terminal needs to consider the characteristic attributes of the location area and the distance from the fire source. The current location of the communication sub-terminal can be determined by GPS data, and it can be determined whether it is in an important area. The sub-terminal that is closer to the fire scene or other emergency location may have a higher priority; the communication quality of the communication sub-terminal can be measured by indicators such as signal strength, packet loss rate, signal stability, and sub-terminal battery status. A sub-terminal with better communication quality means that the information transmission is more stable and reliable; the communication urgency can be determined based on the parameters of the surrounding environment where the sub-terminal is located. The parameters can be determined by data such as the temperature, humidity, and smoke concentration of the environment. Among them, the temperature, humidity, and smoke concentration of the environment are collected and stored by sensors configured on the communication sub-terminal equipment. A worse environment represents a higher degree of urgency. After calculating the priority of each communication sub-end with a request, all communication sub-ends are sorted from high to low according to the priority value, and a communication request queue is created according to the priority. The communication request with the highest priority is placed at the front of the queue. According to the actual application scenario, an update cycle is set to recalculate and update the priority values ​​of all communication sub-ends to generate the latest communication request queue. When a new communication request enters, the priority values ​​of all communication sub-ends are also recalculated and updated to generate the latest communication request queue, ensuring that the optimal communication request can be processed quickly, so as to ensure that communication resources can be effectively managed and scheduled in emergency situations.

[0037] Based on the communication request queue, if there is a communication terminal that is disconnected and released to an idle state, the communication channel with the highest communication level among the remaining channels is selected according to the order of the communication request queue, and the communication sub-end that initiates the communication request is connected to the communication terminal; If there is no idle communication terminal, continue to wait for communication connection according to the order of the communication request queue; If the communication quality of the current communication sub-end is lower than the preset quality threshold when the two ends are communicating, the communication channel with a higher communication level in the current communication connection is first selected for channel switching, and then the communication sub-end is connected to the communication terminal through the switched communication channel with a higher communication level; Specifically, the preset quality threshold can be set according to the actual scenario. If the calculated communication quality is lower than the quality threshold, it means that the communication effect of the current communication sub-end is very poor, and it is necessary to match a communication channel with a higher level for connection. The channel with a higher communication level can be switched out first for the connection of this sub-end to ensure basic communication requirements. If the communication quality is not lower than the quality threshold, the connection can be selected from an unoccupied channel when establishing a communication connection with the communication terminal; If the communication urgency of the current communication sub-end in the communication request queue is higher than the preset urgency threshold, the communication with the longest communication duration in the current communication is cut off, and the mode is switched to recording mode, the voice data of the communication sub-end that has been cut off is collected, stored and sent to the dispatch center, and the communication request of the communication sub-end that is higher than the urgency threshold is received and the communication connection is established; Specifically, the preset urgency threshold can be set according to the actual scenario. If the communication urgency calculated in real time is higher than the urgency threshold, it means that the environment around the communication sub-end is highly unsuitable for personnel to stay and rescue is urgently needed. Therefore, it is necessary to establish communication as soon as possible to understand the actual situation of its location, cut off the communication with the longest communication time in the current communication, arrange the urgency of the communication sub-ends higher than the urgency threshold in descending order, and receive connections to the communication sub-ends in turn. If there is no communication sub-end higher than the urgency threshold, continue to wait for communication connection according to the order of the communication request queue.

[0038] Furthermore, the calculation of the communication priority of the current communication sub-end includes: Evaluation function based on the location area of ​​the communication sub-terminal , calculate the location area evaluation score of the communication sub-terminal, expressed as: ; in, Indicates communication sub-terminal Distance to the nearest fire source, Indicates The scoring function of the position feature, Indicates The importance coefficient of the position feature, represents the number of location features, Represents the influence coefficient of distance on position score; Specifically, the location characteristics of the communication sub-terminal are mainly used to determine the attributes of its location, including but not limited to whether the current location is in an evacuation passage, an important equipment room, a crowded area, etc., to set the score of the location attribute, and to obtain the corresponding attribute score based on the scoring function of the location characteristics, as well as the distance from the communication sub-terminal to the nearest fire source, to comprehensively judge the urgency of the communication sub-terminal.

[0039] According to the communication quality evaluation function of the communication sub-end , calculate the communication quality evaluation score of the communication sub-end, expressed as: ; in, Indicates The value of the communication quality characteristic, Indicates The historical average of the communication quality characteristics, Indicates The standard deviation of the communication quality characteristics, A quantity representing communication quality characteristics; Specifically, communication quality characteristics include but are not limited to signal strength, signal stability, transmission efficiency, and battery power. Signal strength is the signal strength value of the current communication sub-end, signal stability refers to the variation range or variance of the signal strength, transmission efficiency is considered to be the current data transmission rate, and battery power is the current battery power percentage. Their characteristic values, historical averages, and standard deviations are obtained to obtain the communication quality evaluation score of the communication sub-end.

[0040] According to the communication urgency evaluation function of the communication sub-end , calculate the communication urgency evaluation score of the communication sub-end, expressed as: ; in, Indicates the ambient temperature of the communication sub-end, , Represent the minimum and maximum temperature thresholds, Indicates the humidity around the communication sub-end. , Represent the minimum and maximum humidity thresholds, Indicates the smoke density around the communication terminal. , are the minimum and maximum smoke concentration thresholds, , , They represent adjustment parameters respectively, wherein the temperature threshold, humidity threshold, smoke concentration threshold and adjustment parameters can be set according to the spatial range of the actual site; According to the location area evaluation function, communication quality evaluation function and communication urgency evaluation function of the communication sub-terminal, the communication priority of the current communication sub-terminal is calculated, which is expressed as: ; in, Indicates communication sub-terminal The communication priority.

[0041] It should be noted that through environmental perception and urgency assessment, it is ensured that the places that need communication support the most can obtain resources first, thereby improving the overall efficiency of emergency response. Through priority sorting, it is ensured that the most important communication requests can be processed first, thereby speeding up the overall communication response speed. By dynamically adjusting the communication request queue, limited communication resources are allocated more reasonably, improving the resource utilization of the overall system.

[0042] S400, regularly perform communication quality inspection on the communication terminal and the communication sub-terminal, evaluate the communication quality, identify and record communication network or equipment failures, and complete fault reporting and maintenance.

[0043] Preferably, regularly performing communication quality inspection on the communication terminal and the communication sub-terminal includes: Setting periodic tasks, which include periodically sending quality inspection signals between the communication terminal and the communication sub-terminal, and receiving and returning feedback signals by the other party, and recording the communication quality characteristic data during the quality inspection process to evaluate the communication quality; Periodic tasks also include detecting communication network or equipment faults, recording detected fault information, generating fault reports, reporting the fault reports, performing fault maintenance, and recording fault maintenance information.

[0044] It should be noted that through regular quality inspection and fault reporting of the communication terminal, the reliability and stability of the communication system are guaranteed, communication interruptions due to equipment failures are reduced, and at the same time, the manual operation process is simplified and the risk of misoperation is reduced.

[0052] Referring to Table 1, an embodiment of the present invention provides a fire emergency communication method. In order to verify its beneficial effects, comparison results of two solutions are provided.

[0053] The method of the present invention is used to verify its effectiveness in responding to emergency situations, especially its processing capability and response speed when faced with a large number of communication requests, and is compared with traditional fire emergency communication methods.

[0054] In a simulation of a sudden fire incident, each communication sub-terminal initiates a communication request, and the fire command center (communication terminal) needs to process communication requests from multiple different locations at the same time, including some communication terminals that are already in use. The experimental results are shown in Table 1.

It can be seen from Table 1 that compared with the traditional method, this method has significant advantages in response speed, communication success rate, etc., especially in emergency situations, it can respond to requests faster and maintain a higher communication success rate, which is crucial for timely and effective rescue work.
