When the communication exercise is carried out, the communication frequency and the communication intensity can be flexibly adjusted and set according to actual needs so as to detect the corresponding system load resistance.

If both the system delay and the system reliability are satisfactory, the active line 310 and the standby line 320 are interchanged, i.e., the current standby line 320 is converted into the active line 310, and the original active line 310 is converted into the standby line 320.

By the design, the system delay detection and the system load resistance detection are carried out on the standby line 320, normal use of the active line 310 is not affected and disturbed, and even if an emergency alarm occurs in the process of carrying out the system delay detection and the system load resistance detection, the emergency alarm can be smoothly transmitted through the active line 310, so that the first time response is ensured.

In this way, a stable and reliable communication line can be continuously provided for the command terminal 100 and the response terminal 200, and stability detection can be performed on the line converted after a period of use, so that continuous and stable use of the communication line is ensured.

Thus, not only is the preparation of excessive standby lines 320 unnecessary, but also the utilization rate of each line can be improved, and the communication stability and reliability are ensured, and meanwhile, the resource saving is realized, so that the method is very suitable for common villages and remote villages.

In general, the rural emergency command information system provided by the embodiment can effectively ensure the stability and smoothness of emergency management communication, so that an emergency treatment instruction can be smoothly issued and executed, and has positive significance in reducing life and property risks of masses and reducing overall loss.

It should be noted that, at the command end 100 and the response end 200, the priority of the communication transmission of the active line 310 is greater than that of the standby line 320, that is, if a real emergency situation occurs, even if the system delay detection and the system load resistance detection are performed, the response work to the real emergency situation is not affected.

In this embodiment, both the command terminal 100 and the response terminal 200 are provided with communication databases, and when performing communication exercise, both the command terminal 100 and the response terminal 200 extract communication data from the communication databases for communication transmission. In this way, the communication drilling process can be automatically carried out without manual participation, and the manpower loss and waste are reduced.

Further, the rural emergency command information system further comprises: the communication is interrupted to an emergency unit. The communication interruption emergency unit includes: the mobile communication base station is mounted on the unmanned aerial vehicle and is used for establishing temporary communication between the command end 100 and the response end 200.

In the process of executing the emergency work, if communication interruption occurs, the communication interruption emergency unit determines the arrangement scheme of the mobile communication base station according to the distribution condition of the command end 100 and the response end 200, the communication range requirement and the effective coverage range of the mobile communication base station, and controls the unmanned aerial vehicle to convey the mobile communication base station to a designated position.

The mobile communication base stations are all powered by the storage battery, so that a temporary communication network can be constructed, and normal communication between the command end 100 and the response end 200 is ensured, so that smooth and orderly development of first-line emergency work is ensured.

In the actual use process, the unmanned aerial vehicle carrying the mobile communication base station of the next batch is prepared in advance according to the endurance capacity of the storage battery, so as to ensure the continuous smoothness of the temporary communication network.

Further, the communication interruption emergency unit further includes: and the image acquisition module is arranged on the unmanned aerial vehicle. The image acquisition module is in a closed state by default.

When the worker at the response end 200 is assigned to the designated location to perform the task, the communication interruption emergency unit deploys an unmanned aerial vehicle to follow the response end 200, and activates the image acquisition module of the unmanned aerial vehicle to perform safety supervision on the executor at the response end 200.

By the design, the safety of the executive can be remotely monitored at any time even if the executive independently acts. Therefore, the safety of executive personnel can be ensured, reasonable distribution of work of the emergency executive personnel can be facilitated in emergency first-line, and the probability of insufficient hands is reduced.

Meanwhile, as the unmanned aerial vehicle follows the executive, the signal intensity of the position of the executive can be effectively ensured, and the executive is facilitated to timely feed back the first-line situation to the command terminal 100. In addition, even if the position of an executive is in danger, the executive is trapped, the unmanned aerial vehicle can capture images in time, and meanwhile, the communication can be kept smooth due to the strong enough signal strength, so that the trapped executive can be rescued in the first time.

Further, the communication interruption emergency unit is further configured to execute a road emergency processing procedure, where the road emergency processing procedure includes:

S1, determining a road route 400 externally connected locally, and respectively shifting lines of the road route 400 to two sides to obtain offset lines 410, wherein the offset distance is equal to the effective visible distance of the image acquisition module under the current weather condition, and the two offset lines 410 enclose a line planning limit range. As shown in fig. 2.

S2, planning the unmanned aerial vehicle flight line 420 within a line planning limit range so as to enable the unmanned aerial vehicle flight line 420 to be shortest. As shown in fig. 3.

S3, the unmanned aerial vehicle is assigned to fly along the unmanned aerial vehicle flight line 420, the image acquisition module of the unmanned aerial vehicle is activated to check the road condition of the road route 400, and meanwhile, the emergency distress signal and the road condition along the road are periodically sent outwards.

In this way, the unmanned aerial vehicle flies from the local place to other nearby villages and urban areas along the unmanned aerial vehicle flying line 420, whether the road is smooth can be determined along the way, and meanwhile, the emergency distress signal and the road condition along the way are periodically sent outwards, so that even if relevant information is received by surrounding villages and urban areas, a reasonable and accurate emergency rescue scheme can be made at the first time.

It should be noted that, when an emergency situation occurs in a country or urban area around and communication is interrupted, the surrounding country or urban area may send out the unmanned aerial vehicle to the target location along the unmanned aerial vehicle flight line 420, collect the road condition information along the way, and continuously receive the emergency distress signal and the road condition signal sent out by the unmanned aerial vehicle possibly sent out by the target location. This effectively shortens the signal on time.

Further, the step S2 specifically includes:

S21, obtaining shielding elements 500 on two sides of the road route 400, wherein the shielding elements 500 comprise terrains, houses and plants (including but not limited to trees). As shown in fig. 4.

S22, determining a view shielding area 510 within a line planning limit range according to shielding conditions of the shielding element 500 on the road route 400, the flying height of the unmanned aerial vehicle and the effective visible distance of the image acquisition module under the current weather condition. As shown in fig. 5.

S23, planning the unmanned aerial vehicle flight line 420 in the area of the open-view shielding area 510 in the limit range of the line planning so as to enable the unmanned aerial vehicle flight line 420 to be shortest. As shown in fig. 6.

By the design, the road condition overall view of the road can be effectively ensured.

Optionally, step S22 may further include:

s221, constructing a three-dimensional model of a region corresponding to the line planning limit range, and defining the height upper limit of the three-dimensional model by utilizing the maximum flying height of the unmanned aerial vehicle and a smaller value in the effective visible distance under the current weather condition.

S222, determining a flight range 520 of each road section capable of acquiring the full view of the road condition according to the shielding condition of the shielding element 500 on the road route 400, marking the flight range 520 in the three-dimensional model, and forming a view shielding area 510 outside the flight range 520, as shown in fig. 7 and 8. By means of the three-dimensional model, the path can be shortened more stereoscopically.

For special situations, for example, the visible distance is shortened due to poor weather conditions, or the shielding element of the road shields the road surface seriously, and for a certain road section, the situation that the unmanned aerial vehicle cannot acquire the road condition overall view of the road section in a height area above the lowest flying height may occur. At this time, the minimum passing width required for emergency rescue is confirmed. And determining the flyable range of the pavement area corresponding to the minimum passing width on the pavement by the unmanned aerial vehicle according to the model.

When the unmanned aerial vehicle passes through the road section, the unmanned aerial vehicle is controlled to fly in a flyable range, and road surface image data of the corresponding minimum passing width of different areas on a road surface are obtained by adjusting the position of the unmanned aerial vehicle in the flyable range.

When the road surface with the minimum traffic width meets the traffic requirement, namely, the actual road surface width meeting the traffic requirement of the road section is confirmed to meet the minimum traffic width requirement, the unmanned aerial vehicle can be controlled to continuously fly forwards, and the confirmation work of the subsequent road section is continuously executed.

In this way, even if the field of view is severely limited, it is possible to confirm whether the road meets the basic rescue requirement, and to reduce the influence on the timeliness of the rescue signal transmission and the unmanned aerial vehicle traveling efficiency as much as possible.

Through the design, the last determined unmanned aerial vehicle flight line 420 can be as short as possible, so that the unmanned aerial vehicle can fly farther along the road line 400, the flight efficiency can be effectively improved, the emergency distress signal can be transmitted as soon as possible, and meanwhile, the confirmation of the road condition overall view can be ensured to be successfully completed. According to the confirmed road condition information, surrounding villages and cities are convenient to avoid unsmooth roads, and rescue is timely carried out on a target area.

In the specific implementation process, the road condition confirmation range can be determined according to the actual influence degree of the emergency on the road (for example, the influence degree of earthquake, strong wind and storm on the road is relatively large), and the unmanned aerial vehicle flies according to the unmanned aerial vehicle flight line 420 confirmed in the road condition confirmation range so as to ensure the road condition of the road nearby locally. When the unmanned aerial vehicle flies out of the road condition confirmation range, the unmanned aerial vehicle flies directly to the nearby villages and cities so as to send the emergency distress signal in time.

In summary, the rural emergency command information system provided by the embodiment of the invention can effectively ensure the stability and smoothness of emergency management communication, so that the emergency treatment instruction can be smoothly issued and executed, and has positive significance in reducing the lives and property risks of the masses and reducing the overall loss.

The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
