Specifically, the communication base station 1 may adopt a communication tower near a disaster site, or may adopt an emergency communication vehicle or an emergency communication station, and the like, and the preset mobile terminal may adopt a mobile phone, an intercom, or an intelligent bracelet, and the intelligent bracelet is taken as an example in this embodiment. The information transmission mode between the communication base station 1 and the intelligent bracelet adopts wireless transmission, for example, NB-IoT, wifi, loRa and other communication technologies are adopted, and the command center carries out information interaction with the intelligent bracelet of the rescue worker 3 through a communication tower or an emergency communication vehicle and the like, so that the command center can know the situation on site conveniently.
S200: judging whether the signal intensity is lower than a set intensity value;
if yes, outputting an allocation signal for deploying the temporary repeater 2, and controlling the temporary repeater 2 to be in signal connection with the communication base station 1 and the mobile terminal respectively.
Specifically, the communication base station 1, the temporary repeater 2 and the smart bracelet are all integrated with communication modules such as NB-IoT, the smart bracelet can detect the signal strength of a communication link between the smart bracelet and the communication base station 1, the signal strength can be compared by RSRP or RSRQ, if the RSRP is taken as the reference, a set strength value can be-100 dBm, that is, when the signal strength of the communication link between the smart bracelet and the communication base station 1 is lower than-100 dBm, the signal is poor, the temporary repeater 2 needs to be deployed, for example, the temporary repeater 2 is placed in a backpack carried by a rescuer 3, the temporary repeater 2 is pasted on the ground or a wall when the temporary repeater needs to be deployed, the temporary repeater 2 can also be automatically deployed through an automatic blanking device, and the automatic blanking device can adopt a structure similar to an automatic pitching machine, and is used for automatically shooting the temporary repeater 2. The temporary repeater 2 can adopt a wireless repeater of an NLM5xx model, is configured with an independent battery for power supply, and is automatically connected with the communication base station 1 and the intelligent bracelet during starting, so that signal endurance is realized, and the signal coverage range is enlarged.
S300: and executing a checking operation: acquiring the signal intensity between the temporary repeater 2 and a preset mobile terminal, and judging whether the signal intensity is lower than a set intensity value;
if yes, outputting an allocation signal for deploying another temporary repeater 2, and controlling the temporary repeater 2 to be in signal connection with the previous temporary repeater 2 and the mobile terminal respectively.
The checking operation is repeatedly performed and the mobile terminal is controlled to maintain the signal connection with the communication base station 1.
Specifically, when the rescue workers 3 continuously go deep into the disaster site, more temporary repeaters 2 need to be deployed to extend the communication link, so as to ensure stable transmission of information between the smart band and the communication base station 1. Last temporary repeater 2 can be automatic to be connected with the disconnection of intelligent bracelet and with the temporary repeater 2 of new deployment, and the temporary repeater 2 of new deployment is connected with the intelligent bracelet again, and the temporary repeater 2 of first deployment sets for priority in advance and connects communication base 1 and intelligent bracelet promptly, then switches over when next temporary repeater 2 is enabled and is connected to next temporary repeater 2. And starting from the second deployed temporary repeater 2, each temporary repeater 2 is preset to preferentially connect the previous temporary repeater 2 with the smart band. The activation sequence between the temporary repeaters 2 is specified in advance by the worker.
Referring to fig. 1 and 3, when a communication link is established by the temporary repeater 2, the following steps are performed for each temporary repeater 2 deployed:
s311: the position information of the temporary repeater 2 is acquired as the end position at the present time.
Specifically, the temporary repeater 2 may be integrated with a GPS chip, or may be located by a GPS positioning function of the smart band during deployment, and marked as a coordinate position of the currently deployed temporary repeater 2.
S312: and acquiring the position information of the rest deployed temporary repeaters 2 as the position of the path point at the current moment.
Specifically, the position information of each temporary repeater 2 is recorded and stored to form one-to-one corresponding path points.
S313: generating a moving route according to the communication base station 1, the position of the path point and the position of the destination point;
s314: the newly generated movement route is transmitted to the communication base station 1 through the communication link.
Specifically, the communication base station 1 can be used as a starting point, or a positioning point when the smart bracelet is started is used as a starting point, each deployed temporary relay 2 is used as a path point, and the starting point, the path point and the end point are connected according to the connection sequence of the communication links to form a moving route corresponding to the rescue worker 3, so that the command center can know the travelling route of the rescue worker 3 conveniently, and the moving route can be used as a relatively safe reference route for secondary rescue. In other embodiments, the end position may also be a real-time location point of the smart band, so as to improve the location accuracy of the moving route.
In the process of controlling the mobile terminal to maintain signal connection with the communication base station 1, the connection condition of the communication link needs to be monitored in real time, so as to avoid the loss condition of the transmitted information. Referring to fig. 1 and 4, the method specifically includes steps S321 to S323:
s321: the signal strength between the mobile terminal and the communication base station 1 is acquired.
S322: judging whether the signal intensity between the mobile terminal and the communication base station 1 is lower than a preset intensity threshold value or not;
if yes, the signal strength between the communication base station 1 and the temporary repeater 2 is obtained, the signal strength between the temporary repeater 2 and the mobile terminal is obtained, and the signal strength of two adjacent temporary repeaters 2 is obtained when the number of the deployed temporary repeaters 2 is at least two.
Specifically, after the temporary repeater 2 is started, the intelligent bracelet and the communication base station 1 are controlled to automatically send a test signal back and forth to check whether the connection is successful, if the test signal is damaged and lost, connection failure is indicated, and if the connection is successful, whether the signal strength meets the requirement can be judged through the numerical value of the signal strength.
S323: and analyzing the fault objects in the communication base station 1, the temporary repeater 2 and the mobile terminal according to the acquisition result of the signal strength, and adopting a preset emergency scheme according to the analysis result.
Specifically, if the signal strength between the communication base station 1 and the temporary repeater 2 is lower than the preset strength threshold, it indicates that the communication base station 1 or the first deployed temporary repeater 2 has a fault or is unstable in operation, if the signal strength between the last deployed temporary repeater 2 and the smart bracelet is lower than the preset strength threshold, it indicates that the last deployed temporary repeater 2 or the smart bracelet has a fault or is unstable in operation or the distance between the last deployed temporary repeater 2 and the smart bracelet is too far (a new temporary repeater 2 is deployed), and if the signal strength between two adjacent temporary repeaters 2 is lower than the preset strength threshold, it indicates that at least one of the two temporary repeaters 2 has a fault or is unstable in operation, so that a faulty object is conveniently found, and timely maintenance of a communication link is convenient.
Referring to fig. 1 and 5, if the signal between the mobile terminal and the communication base station 1 is basically disconnected and the signal is seriously damaged or lost, the steps S331 to S333 may be adopted to determine the fault object:
s331: acquiring deployment information of all temporary relays 2 which are still in signal connection with the communication base station 1;
s332: and searching the temporary repeater 2 at the tail in the deployment sequence according to the deployment information to serve as a first disconnection point.
Specifically, the signal connection is maintained, that is, the signal strength with the communication base station 1 is maintained in a state of exceeding the preset strength threshold, and the deployment information describes the deployment sequence of each temporary repeater 2, for example, the number, deployment position, and the like of each temporary repeater 2, so that the temporary repeater 2 close to the signal edge on the communication base station 1 side can be found.
S333: and searching the temporary repeater 2 which is positioned at the latest rear position of the temporary repeater 2 in the deployment sequence to be used as a fault point, and calling the deployment position of the temporary repeater 2.
Specifically, the temporary repeater 2 which is generally set after the first disconnection point is located in the deployment sequence and is set at the latest position, namely the disconnection part, can find the position of the fault point by obtaining the deployment position of the temporary repeater, so that the rescue workers 3 can conveniently re-check and deploy the temporary repeater 2, or the commander can conveniently dispatch a new batch of rescue workers 3 to perform maintenance.
The specific emergency scheme comprises the following steps:
searching other temporary repeaters 2 except the temporary repeater 2 at the first disconnection point at the fault point, and judging whether the searched temporary repeaters 2 are the temporary repeaters 2 which are set after the temporary repeaters 2 at the fault point in the deployment sequence are nearest;
if so, the searched temporary repeater 2 is used as a second disconnection point, and the signal intensity of another mobile terminal preset at the fault point and the signal intensity of the temporary repeater 2 at the first disconnection point and the signal intensity of the temporary repeater 2 at the second disconnection point are respectively obtained;
and if the two signal strengths exceed the set strength value, outputting a distribution signal for relocating the temporary repeater 2 at the fault point, and controlling the temporary repeater 2 to be in signal connection with the temporary repeater 2 at the first disconnection point and the temporary repeater 2 at the second disconnection point respectively.
Specifically, the other mobile terminal is a mobile terminal carried by a subsequent support person, and may also be a smart band. When the temporary repeater 2 located at the fault point and found by the smart bracelet is located at the nearest rear position, the temporary repeater 2 can be connected with the two temporary repeaters 2, so that the communication link can be repaired. If two other temporary repeaters 2 appear, the temporary repeater 2 possibly in the fault point is disturbed and deviated from the fault point position, and at this time, the temporary repeater 2 corresponding to the fault point can be reset or connected with the redeployed temporary repeater 2, so that the temporary repeater 2 can be put into use again. If the signal strength of the intelligent bracelet and one of the temporary repeaters 2 exceeds a set strength value and the signal strength of the other temporary repeater does not exceed the set strength value, the intelligent bracelet is controlled to move towards the side with weak signal strength until the two signal strengths exceed the set strength value according to the positions of the first disconnection point and the second disconnection point relative to the fault point, and therefore the position of the drop point where the temporary repeaters 2 need to be redeployed is determined.
If the remaining temporary repeaters 2 except the temporary repeater 2 at the first disconnection point are not found, the positions of the temporary repeaters 2 set after the first disconnection point are determined according to the moving route recorded in the step S314, and the operation of continuously relocating the temporary repeaters 2 is performed, where the deploying mode is consistent with the steps S100 to S300, until the communication base station 1 is successfully connected with the smart bracelet of the first set of rescuers 3.
The emergency scheme adopted can also adopt the following modes: for example, the command center automatically gives an early warning to prompt the staff to perform secondary rescue and repair the communication link, or the intelligent bracelet automatically gives an early warning to prompt the rescue staff 3 to redeploy the idle temporary repeater 2 to repair the communication link.
S400: referring to fig. 1 and 2, emergency information corresponding to a mobile terminal is acquired, and the emergency information is transmitted to a communication base station 1 through a communication link formed by at least one temporary repeater 2.
Specifically, after the communication link is built, the emergency information can be transmitted through the latest communication link, so that the information intercommunication between the command center and the on-site rescue worker 3 is facilitated. Wherein intelligent bracelet integration has sensing module such as acceleration sensor, gyroscope, optics rhythm of the heart sensor, picoelectricity reaction sensor, temperature sensor, baroceptor, also integrates simultaneously has the GPS module for fix a position intelligent bracelet.
The emergency information comprises vital signs of appointed personnel such as the on-site rescue personnel 3 and the like, and is used for facilitating the working personnel of the command center to know the physical condition of the on-site rescue personnel 3, so that the rescue personnel 3 can be rescued in time when in danger, and the safety is improved. In order to reduce the power consumption of the intelligent bracelet, on the premise of not influencing the early warning of vital signs, the content of emergency information is simplified, the transmission frequency is reduced, and thus the emergency information is convenient to manage by a command center, and therefore the following steps SA1-SA3 of triggering the emergency information are set:
SA1: acquiring vital signs of a designated person;
and SA2: comparing the vital signs with a preset normal range;
and SA3: and if at least one vital sign exceeds the corresponding normal range, controlling the mobile terminal to send emergency information to the communication base station 1 through the communication link.
Specifically, the preset normal range can be preset according to the physical quality of the on-site rescue workers 3, the normal range can also be set according to the normal range of the physical signs of normal people, when one of the vital signs such as heart rate exceeds the standard, life danger possibly exists in the rescue workers 3, the emergency information is sent immediately for early warning, and therefore effective emergency information is screened out.
In other embodiments, the manner of triggering the emergency information may also be as shown in steps SB1-SB 3:
SB1: acquiring vital signs of a designated person in real time;
SB2: calculating a sign change rate according to a plurality of continuously sampled vital signs;
SB3: judging whether the change rate of the physical signs exceeds a set rate or not;
and if so, controlling the mobile terminal to send emergency information to the communication base station 1 through the communication link.
Specifically, the vital sign change of the on-site rescue worker 3 generally has a transition process, such as heart rate increase, blood pressure increase and body temperature increase, in order to realize early warning, but not wait for the vital sign to exceed the standard and then perform early warning, so that the change rate of the vital sign can be calculated, the change rate of the vital sign can be a one-way increase rate or a one-way decay rate, the change condition of the vital sign in unit time is represented, and a command center can conveniently make a response in advance, for example, the rescue worker 3 is prompted to pay attention to safety by calling an intelligent bracelet, or the position of the rescue worker 3 is positioned so as to facilitate rescue.
When the rescuer 3 circuitously moves rescuers at the disaster site, there may be a situation where two deployed mobile terminals are close together at the same time, and steps SC1-SC3 may be taken:
SC1: detecting a temporary repeater 2 with the signal intensity near the preset mobile terminal greater than the set intensity value in real time;
specifically, the connectable temporary repeater 2 nearby can be monitored in real time through the smart band, and the temporary repeater 2 with the signal strength meeting the requirement is obtained.
SC2: judging whether the number of the detected temporary repeaters 2 is greater than 2;
if yes, comparing the signal intensity of all searched temporary repeaters 2;
SC3: and outputting a connection signal for controlling the connection of the preset mobile terminal with the temporary repeater 2 with the maximum signal strength.
Specifically, the procedure of selecting the temporary repeater 2 is triggered when the number of the temporary repeaters 2 detected by the smart bracelet is greater than 2, so that the smart bracelet is always connected with the temporary repeater 2 with a stronger signal, and if the signal strength of the temporary repeaters 2 is consistent or the difference value is smaller than a set trigger value, the smart bracelet can be controlled to be connected with the temporary repeater 2 which is set before the deployment sequence, so as to shorten the transmission length of the communication link.
