Description

Technical Field

[0001] The invention relates to a vehicle accident warning system, in particular to a warning network system for preventing highway collapse, highway fog and other chain traffic accidents caused by the like. Background Art

[0002] The use of mobile phones brings a lot of convenience to people's lives, and the development of specific mobile phone software can make people's travel safer.

[0003] When motor vehicles are driving on highways, traffic accidents are prone to occur in poor road conditions. In recent years, traffic accidents caused by roadbed and bridge damage, fog, water accumulation, ice, etc. on highways have occurred from time to time, resulting in major property losses and casualties. For example: On the evening of May 1, 2024, the Meida Expressway in Guangdong collapsed, 23 vehicles fell in a chain, 48 people were killed and 30 people were injured; on the evening of July 19, 2024, heavy rains in Zha County, Shaanxi caused floods and highway bridges to collapse, 25 vehicles fell in a chain, 38 people were killed, and 24 people were lost; on February 1, 2025, the Taihui Expressway section in Henan Province caused a chain accident of hundreds of vehicles rear-ending due to heavy fog and slippery ground. The above chain accidents occurred because after the first motor vehicle had an accident, the driver of the rear vehicle could not understand the danger ahead due to unclear vision and other reasons, resulting in a chain traffic accident of the rear motor vehicle. Therefore, when the first motor vehicle has an accident, issuing a warning to the vehicle following it immediately can effectively avoid the occurrence of such chain accidents.

[0004] When the first motor vehicle fell from the highway, the vehicle may have been seriously damaged and the driver and passengers may have been injured, but the driver and passengers' mobile phone functions may still be in normal working condition, which created conditions for using the mobile phones of the driver and passengers of the accident vehicle to complete the accident alarm.

[0005] CN 118397806 A discloses a method, device and storage medium for abnormal deceleration of motor vehicles on high-speed roads. The method detects and extracts vehicle speed data and vehicle position data through the vehicle's own speed detection device or vehicle navigation software. When the vehicle's driving speed data is abnormal, the information is pushed to the vehicle terminals of all running vehicles in the upstream range of the abnormal running state vehicle or published on the Internet navigation road conditions to avoid secondary accidents. However, according to investigations by relevant departments, many vehicles are not equipped with vehicle-mounted electronic terminals, and in many cases, drivers do not use navigation software when driving. Once an accident occurs, the real-time extraction, detection, publication and reception of relevant data may not be realized, so it is not possible to effectively prevent and avoid secondary accidents in a timely manner. In addition, the published scheme cannot identify and judge traffic accidents caused by the collapse of road surfaces and bridges that cause the vehicle to fall, and cannot achieve effective early warning and treatment effects for this special vehicle traffic accident. Summary of the invention

[0006] The present invention aims to solve the problem that the prior art cannot effectively warn and handle traffic accidents caused by moving vehicles due to collapse of road surfaces and bridges, fog on highways, waterlogging and icing on the road, etc. For this purpose, a traffic accident warning system of the present invention is provided, which combines a mobile phone background running software program with a background communication mechanism. This warning system can warn of traffic accidents caused by collapse of road surfaces and bridges on highways, fog on highways, waterlogging and icing on the road, etc., to prevent chain traffic accidents caused by subsequent vehicles of the accident vehicle on the road.

[0007] In order to solve the above problems, the technical solution adopted by the present invention is special in that the software program running in the background of the mobile phone has an accident perception and accident information transmission module, which has:

[0008] (1) A data capture unit, which captures the GPS speed data of the vehicle at the current moment and the previous moment, as well as the trajectory coordinate information of the time period before the current moment;

[0009] (2) a data calculation, comparison and judgment unit, which calculates the speed data difference between the current moment and the previous moment of the moving vehicle, compares the speed data difference with a critical value, and judges that the vehicle has a traffic accident when the speed data difference is greater than the critical value;

[0010] (3) an information sending unit, which sends the track coordinate information of the accident vehicle to the background communication mechanism when it is determined that the vehicle has an accident;

[0011] (4) an information receiving unit, receiving the accident vehicle trajectory coordinate information and warning text information sent by the background communication mechanism;

[0012] (5) an information prompting unit, which broadcasts the received warning text information in a voice prompting manner;

[0013] The background communication mechanism has an accident information transmission module, which has:

[0014] (1) a track coordinate information receiving unit, which receives the track coordinate information of the accident vehicle sent by the software program running in the background of the mobile phone;

[0015] (2) a warning text information generating unit, which generates a warning text information by combining the received trajectory coordinate information with preset text;

[0016] (3) A warning text information sending unit, which sends the warning text information to the background software program of the mobile phones of the accident vehicle and all the drivers and passengers of the vehicles behind it.

[0017] If the speed data difference is greater than a critical value, it is determined that the vehicle has a traffic accident, and the traffic accident is mostly a vehicle collision accident.

[0018] Furthermore, the (1) data capture unit of the accident perception and accident information transmission module of the software program running in the background of the mobile phone also captures the barometric needle altitude data of the moving vehicle at the current moment and at the previous moment, and the (2) data calculation, comparison and judgment unit also calculates the altitude data difference between the moving vehicle at the current moment and at the previous moment, and compares the altitude data difference with a critical value. When the altitude data difference is greater than the critical value, it is determined that the vehicle has a fall accident.

[0019] Furthermore, the software program running in the background of the mobile phone is automatically started when the mobile phone is in standby mode or other applications are turned on and when the vehicle is traveling at high speed.

[0020] The high-speed driving of a vehicle refers to a vehicle driving speed ≥ 80 km / h.

[0021] It is suitable that the time interval between the current moment of the traveling vehicle and the previous moment is the mobile phone GPS navigation update time interval.

[0022] More preferably, the time interval is 1 second.

[0023] The information interaction between the background running software program of the mobile phone of the present invention and the background communication mechanism is realized through the transfer of the communication base station.

[0024] The vehicle crew members described in the present invention include a driver and passengers.

[0025] The mobile phone background running software program of the present invention can be configured for use by all non-specific vehicle drivers and passengers.

[0026] The background communication mechanism receives the vehicle trajectory coordinate information sent by the background software program running on the background of the accident vehicle's mobile phone, and sends this information to the background software programs running on the background of the mobile phones of all drivers and passengers of vehicles on the road section behind the accident vehicle. It also sends this information to the background software programs running on the background of the mobile phones of the drivers and passengers of the accident vehicle, because the accident vehicle is random and non-specific.

[0027] After the vehicle behind the accident vehicle receives the trajectory coordinate information of the accident vehicle through the software program running in the background of the mobile phone, when the trajectory coordinates match the longitudinal and longitudinal coordinates of the vehicle to be driven, the mobile phone software automatically broadcasts voice warning information, and the driver can take risk avoidance measures in time to avoid a chain accident. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 It is a schematic block diagram of the structure of the present invention. DETAILED DESCRIPTION

[0029] Embodiment 1

[0030] like Figure 1As shown, the present invention is a traffic accident warning system that combines a mobile phone background running program with a platform communication mechanism, which has a mobile phone background running software program configured by vehicle drivers and passengers, a communication base station and a background communication mechanism.

[0031] The software program running in the background of the mobile phone has an accident perception and accident information transmission module, which has:

[0032] (1) A data capture unit, which captures the current and previous barometric altitude data, GPS speed data, and track coordinate information of the vehicle in the period before the current time;

[0033] (2) a data calculation, comparison and judgment unit, which calculates the altitude data difference and the speed data difference of the moving vehicle at the current moment and the previous moment, and compares the data difference with a critical value. When the altitude data difference is greater than the critical value, it is judged that the vehicle has fallen; when the speed data difference is greater than the critical value, it is judged that the vehicle has crashed;

[0034] (3) an information sending unit, which sends the track coordinate information of the accident vehicle to the background warning system when it is determined that the vehicle has an accident;

[0035] (4) an information receiving unit, receiving the accident vehicle trajectory coordinate information and warning text information sent by the background communication mechanism;

[0036] (5) An information prompting unit is configured to provide a voice prompt for the received warning text information.

[0037] The background communication mechanism has an accident information transmission module, which has:

[0038] (1) a track coordinate information receiving unit, which receives the track coordinate information of the accident vehicle sent by the software program running in the background of the mobile phone;

[0039] (2) a warning text information generating unit, which generates a warning text information by combining the received trajectory coordinate information with preset text;

[0040] (3) A warning text information sending unit, which sends the warning text information to the background software program of the mobile phones of the accident vehicle and all the drivers and passengers of the vehicles behind it.

[0041] The software program running in the background of the mobile phone is automatically started when the mobile phone is in standby mode or other application is turned on, and when the vehicle is traveling at a high speed. The vehicle traveling at a high speed means that the vehicle travels at a speed of ≥ 80 kilometers per hour.

[0042] The time interval between the current moment of the traveling vehicle and the previous moment is the mobile phone GPS navigation update time interval, and the present invention sets the time interval to 1 second.

[0043] The preset text of the warning text information generation unit of the background communication mechanism is the constituent words and characters of the warning text information, which is combined with the trajectory coordinate information to generate the warning text information. The warning text information includes the distance data between the moving vehicle and the accident vehicle, such as: "Danger 1 kilometer ahead...", "Accident occurred 800 meters ahead...".

[0044] The communication base station is a device for the mobile phone to exchange information with the background communication mechanism through the software program running in the background. The device is generally suitable for being built on the side of a highway or near it.

[0045] The present invention is equipped with a mobile phone background running software program used by vehicle drivers and passengers. When the vehicle is traveling on a highway, the mobile phone background running software program automatically captures the vehicle's current and previous barometric needle altitude data and GPS speed data, calculates the difference between the vehicle's current and previous barometric needle altitude data and GPS speed data, and then compares the two data differences with corresponding critical values, thereby determining whether the vehicle has an accident. The time interval between the current and previous moments of the traveling vehicle is typically 1 second.

[0046] After the software program running in the background of the mobile phone of the driver and passengers of the vehicle behind the accident vehicle receives the trajectory coordinate information and warning text information of the accident vehicle sent by the background communication agency, when the latitude and longitude coordinates of their own vehicle match the trajectory coordinates, the software program running in the background of the mobile phone automatically broadcasts the voice warning information, and the driver can take risk avoidance measures in time to avoid chain accidents.

[0047] The altitude data difference between the current moment and the previous moment is typically based on the current moment and moved forward 1 second. The difference in altitude between the vehicle before and after the 1-second period is calculated if the vehicle falls rapidly at a free fall speed (acceleration 9.8 m / s) within the 1-second period. 2 ), then the difference in altitude will be abnormal. According to the design requirements of the expressway, the limit value of the slope of the expressway with a speed of 100 kilometers per hour is 3%, and the vehicle travels about 27 meters per second when driving at a speed of 100 kilometers per hour. According to the limit value of the slope of the expressway of 3%, the difference between the front and rear of the 27-meter section is 0.81 meters, that is, the vehicle travels downhill, and the altitude drops by 0.8 meters per second. This is the altitude drop speed of the vehicle traveling downhill at the extreme slope of the expressway. Based on this fact, combined with a safety value, it is appropriate to set the critical value of the altitude data difference to 2 meters per second. If the altitude data difference of the moving vehicle is greater than the critical value, it can be determined that the vehicle has fallen.

[0048] The GPS speed data difference between the current moment and the previous moment of the vehicle is the speed value calculated 1 second before the current moment of the vehicle minus the speed value calculated 1 second before the current moment of the vehicle. If the data difference is greater than the normal braking speed data difference of the vehicle, it can be determined that the vehicle has a collision accident. Because the maximum speed drop of a motor vehicle (including a large load-carrying vehicle and a small passenger car) during normal braking is about 15%-25% per 1 second, that is, when the vehicle brakes at a speed of 100 kilometers per hour, the maximum speed difference of a 1-second time interval is about 15 kilometers per hour-25 kilometers per hour. It is reasonable to set the critical value of the vehicle driving GPS speed data difference to be appropriately greater than this value. Based on this, the present invention sets the critical value of the vehicle driving GPS speed data difference to 50 kilometers per hour. The speed difference before and after the normal braking in the 1-second time period is 15-25 kilometers per hour, which is less than 50 kilometers per hour, and belongs to normal braking deceleration. If a vehicle is involved in a collision, it can be reasonably assessed that the vehicle speed drops from 100 km / h to 10-0 km / h in a 1-second time interval, that is, the speed difference before and after the 1-second time period is 90 km / h-100 km / h. This value is greater than 50 km / h, and it can be reasonably determined that the vehicle has been involved in a collision. The collision specifically refers to a collision stop.

[0049] The present invention is implemented in combination with existing commonly used components to achieve beneficial effects in that the mobile phone software can sense the accident by itself, automatically upload the alarm, automatically edit and forward the warning text information after the background receives the alarm information, and the mobile phone software automatically broadcasts the warning text information in voice after receiving the background, basically realizing the online live warning function of major traffic accidents. The present invention can avoid chain accidents after vehicle falls and collisions, and is also helpful for rescuing and helping the accident vehicle and its drivers and passengers.
