Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle equipment, and particularly relates to an emergency communication device for intelligent connected vehicles. Background Art

[0002] The goal of the V2X cloud control module is to enable effective communication and connection between connected vehicles and roadside traffic facilities and equipment. The V2X cloud control module first has the ability to communicate with roadside devices, supports docking with different types and manufacturers of devices, and realizes the full-life cycle management of devices, including device creation, device monitoring, and operation and maintenance alarms.

[0003] The C-V2X connected roadside devices are linked with the V2X service management subsystem. The system can perform cloud monitoring on traffic events detected by roadside devices. At the same time, based on the capabilities provided by the digital twin base, it can control roadside devices through the cloud, realize efficient connection of vehicles, roads, and clouds, build a data interaction system between vehicles, roads, and clouds, and cooperate to realize some intelligent connected scenarios. In addition, this subsystem also has the ability to generate and distribute simulated event scenarios, can simulate and implement some V2I scenarios to cooperate with the development of test services and reduce test costs.

[0004] An intelligent connected vehicle refers to the organic combination of the vehicle network and intelligent vehicles. It is equipped with advanced on-vehicle sensors, controllers, actuators and other devices, and integrates modern communication and network technologies to realize intelligent information exchange and sharing between vehicles and people, roads, and the background, realize safe, comfortable, energy-saving, and efficient driving, and ultimately can replace humans to operate a new generation of vehicles. Intelligent connected vehicles are a new type of vehicle system that crosses technical and industrial fields, focusing on solving core problems such as safety, energy conservation, and environmental protection that restrict industrial development. They have the ability of autonomous environmental perception, with the focus on the vehicle and the development emphasis on improving vehicle safety.

[0005] However, when the in-vehicle network of existing communication emergency devices is damaged, they cannot be connected to the network and cannot send data to the background. Moreover, when existing communication emergency devices are subjected to major or relatively severe impacts, they are extremely easy to be damaged, resulting in the loss of internal data and communication interruption, and unable to upload data to the background in a timely manner. In some remote areas, the base stations are far away, and sometimes wireless information cannot be sent. At this time, satellite communication is required, but it is relatively difficult for satellite communication to still work normally when the communication emergency device is damaged.

[0006] Therefore, we provide an emergency communication device for intelligent connected vehicles to solve the above problems. Summary of the Invention

[0007] The purpose of the present invention is to provide an emergency communication device for intelligent connected vehicles. By adding a protective box body with high protection strength, a shock-absorbing protective sleeve, and adding two-stage satellite communication, the problems of the existing emergency communication being easily damaged when subjected to a major impact, unable to upload data and information, and unable to effectively upload data without a network are solved.

[0008] To solve the above technical problems, the present invention is realized through the following technical solutions: The present invention is an emergency communication device for intelligent connected vehicles, including an installation box and a communication system; the installation box includes a protective box body, a shock-absorbing protective sleeve, and a communication assembly box. Multiple heat dissipation strip holes are provided on both side walls and the rear side wall of the protective box body. An installation bottom plate is fixed at the bottom of the protective box body. The shock-absorbing protective sleeve includes a foam box cover and a foam front plug. The communication assembly box includes a shielding box and a shielding cover. The shielding cover is fixed to the front side of the shielding box with bolts, and then the communication assembly box is inserted into the foam box cover, and the foam box cover is inserted into the protective box body. A foam front plug is blocked in the protective box body on the front side of the foam box cover. A protective cover is fixed on the front side of the protective box body; The communication system includes a V2X cloud control module, an internal satellite communication, and an external satellite communication. The V2X cloud control module and the internal satellite communication are installed in the shielding box. An inwardly concave installation cavity is provided on one side wall of the shielding box, and the external satellite communication is installed in the installation cavity. The V2X cloud control module is data-connected to the vehicle-mounted control system. The vehicle-mounted control system includes a vehicle-mounted navigation and a vehicle monitoring module. The V2X cloud control module can also communicate with roadside devices. The V2X cloud control module is built-in with a wireless network and can also be connected to the vehicle-mounted network.

[0009] The present invention is further configured such that when the vehicle encounters a collision, the vehicle-mounted network is preferentially used to send the location and situation of the car accident. If the vehicle-mounted network is damaged, the internal satellite communication is activated to send the location and situation of the car accident. A satellite antenna is installed on the installation bottom plate beside the protective box body. When the V2X cloud control module in the shielding box is also damaged and the external satellite communication is not controlled by the V2X cloud control module, the external satellite communication activates the function of sending a wireless satellite signal; The shielding box is equipped with a primary backup battery. When the vehicle-mounted battery cannot supply power, the V2X cloud control module activates the primary backup battery to supply power. The external satellite communication is provided with a secondary backup battery to independently supply power to the external satellite communication.

[0010] The present invention is further configured such that the in-vehicle navigation has the function of reminding in advance whether the road ahead is congested, whether there is road repair, and whether a traffic accident occurs on the navigation route. The vehicle monitoring module includes a vehicle performance monitoring unit, a 360-degree imaging and radar system. The vehicle's operating status is monitored in real time by the vehicle performance monitoring unit. The 360-degree imaging and radar system makes judgments on surrounding obstacles and speed during the vehicle's driving process. The vehicle's driving status is judged by analyzing the data collected by the in-vehicle navigation and vehicle monitoring modules. When a traffic accident occurs, the cause of the accident is analyzed and sent to the background center through the communication system.

[0011] The present invention is further configured as follows: the roadside equipment includes a MEC device and an OBU device, the MEC device is installed beside some roads, and the OBU device is installed in the middle position of the top of the front windshield. The detection of the MEC device is a traffic event identified by the algorithm model of the MEC device and reported to the cloud control platform. Traffic events include parking, occupying the emergency lane, driving in the wrong direction, pedestrian intrusion, non-motor vehicle intrusion and congestion. When a vehicle enters a road with a MEC device, the V2X cloud control module will use the vehicle network to obtain the traffic event uploaded by the MEC device. The OBU device is used to detect the vehicle's warning information, and the warning information includes forward collision warning, intersection collision warning, emergency braking warning and vehicle loss of control warning. The warning information is transmitted to the MEC device and reported to the cloud through the MEC device.

[0012] The present invention is further configured such that a storage module is installed in the shielding box, the storage module uses Redis as a cache framework, a database is arranged in the storage module, and the system adopts a database read-write separation mode, with one master and multiple slaves, the master database is only responsible for writing, and the slave database is only responsible for reading data.

[0013] The present invention is further configured such that, during the driving process of the vehicle, the driving recorder on the vehicle is connected to the V2X cloud control module, and the video captured by the driving recorder will be transmitted and backed up in the storage module. When a traffic accident or vehicle failure occurs in the vehicle, the video captured some time before the occurrence time will be uploaded to the background.

[0014] The present invention is further configured as follows: the protection box body is a steel frame box body, the wall thickness of the protection box body is 8-12mm, the foam box cover and the foam front seal are both honeycomb foam sponges, the foam box cover has a large square hole on the left and right side walls and the rear side wall, the foam front seal is evenly provided with air holes, and the side wall thickness of the foam box cover and the foam front seal thickness are both 20-30mm.

[0015] The present invention is further configured such that uniform ventilation pores are formed on both side walls of the shielding box. The shielding box is provided with terminal blocks on both side walls. Electrical devices inside the shielding box are connected to the inner sides of the terminal blocks through wires. The outer sides of the terminal blocks are data-connected to the vehicle-mounted system through data lines. A cooling fan is provided inside the shielding box, and the cooling fan can suck the air outside one side wall of the shielding box and discharge it from the other side wall for heat dissipation.

[0016] The present invention is further configured such that a device software upgrade unit is provided inside the shielding box. When the device software upgrade unit manages the on-vehicle devices, when an upgrade request is sent by the manufacturer or a user requests an upgrade, it can be upgraded through OTA upgrade management.

[0017] The present invention has the following beneficial effects: 1. The installation box of the present invention includes a protective box body, a shock-absorbing protective sleeve, and a communication assembly box. The protective box body can withstand greater impacts without deformation while ensuring heat dissipation and wire arrangement. When impacted, the foam box cover can absorb a large impact without damaging the communication assembly box, and it also has strong support. The communication assembly box is installed inside the foam box cover, and a plurality of relatively large holes are formed in the foam box cover for exhaust heat dissipation and wire arrangement. Only the edge position of the communication assembly box is effectively fixed, with firm fixation and good protection effect.

[0018] 2. When the present invention is subjected to a major impact, when the vehicle-mounted network and the V2X cloud control module are damaged, two-stage satellite communication can be activated. When the vehicle-mounted network cannot be used or connected, a primary backup battery is activated to supply power to the communication system. The built-in satellite communication sends satellite signals to the outside through an antenna. However, when the entire shielding box is damaged, the external satellite communication has a unique structure with extremely high protection. Its outer shell can withstand a large impact. At this time, it plays a role in positioning and sending intermittent information so that the rescue team can locate and rescue in remote areas without network based on the satellite information.

[0019] 3. The present invention has a powerful emergency communication system and its management mode. The V2X cloud control module has a cloud control system for the vehicle-road-cloud data interaction system, including device management, device operation and maintenance monitoring, and V2X server, etc. At the same time, it combines the monitoring of MEC detection events and OBU warning events to improve the accuracy and effect of emergency warning. At the same time, it can also combine the vehicle's own performance monitoring unit, 360 imaging, and radar system on the vehicle to predict possible warnings or car accidents during the vehicle's driving process and give early warnings to the driver to prevent accidents.

[0020] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] Please refer to Figures 1-4, the present invention is an emergency communication device for an intelligent connected vehicle, including an installation box and a communication system; the installation box includes a protective box body 1, a shock-absorbing protective sleeve, and a communication assembly box. Multiple heat dissipation strip holes 11 are provided on both side walls and the rear wall of the protective box body 1. An installation bottom plate 2 is fixed to the bottom of the protective box body 1. The shock-absorbing protective sleeve includes a foam box cover 3 and a foam front plug 31. The communication assembly box includes a shielding box 4 and a shielding cover 42. The shielding cover 42 is fixed to the front side of the shielding box 4 with bolts. Then, the communication assembly box is inserted into the foam box cover 3, and the foam box cover 3 is inserted into the protective box body 1. A foam front plug 31 is blocked in the protective box body 1 in front of the foam box cover 3. A protective cover 12 is fixed to the front side of the protective box body 1; The installation bottom plate 2 and the protective box body 1 are an integral steel plate. The installation bottom plate 2 extends outward for installation and is provided with installation bolt holes. The foam box cover 3 is press-fitted into the protective box body 1 (about 1 mm of foam is squeezed and then inserted). After the shielding box 4 and the shielding cover 42 are installed, they are inserted into the foam box cover 3. First, the wires need to be arranged. The wires are inserted through the large square hole on the foam box cover 3 and connected to the wiring seat on the side wall of the shielding box 4. When the foam box cover 3 is inserted, then the foam front plug 31 is blocked. Then, the protective cover 12 is installed (fixed to the front side of the protective box body 1 with bolts).

[0030] The communication system includes a V2X cloud control module, an internal satellite communication, and an external satellite communication. The V2X cloud control module and the internal satellite communication are installed in the shielding box 4. An inwardly concave installation cavity 41 is provided on one side wall of the shielding box 4, and the external satellite communication is installed in the installation cavity 41. The V2X cloud control module is data-connected to the vehicle control system. The vehicle control system includes a vehicle navigation and a vehicle monitoring module. The V2X cloud control module can also communicate with roadside devices. The V2X cloud control module is built-in with a wireless network and can also be connected to the vehicle network.

[0031] The goal of the V2X cloud control module is to enable effective communication and connection between connected vehicles and roadside traffic facilities and equipment. The V2X cloud control module is also provided with a control chip to receive information within the vehicle system and be connected to the vehicle network, that is, a control chip is added to the V2X cloud control module to process data. Both the internal satellite communication and the external satellite communication are satellite phones and can send pictures, data, and location information.

[0032] The vehicle control system is the vehicle system existing in vehicles and has functions such as vehicle navigation, vehicle performance monitoring, and vehicle cruise.

[0033] When the vehicle encounters a collision, the in-vehicle network is preferentially used to send the location and situation of the car accident. If the in-vehicle network is damaged, the built-in satellite communication is activated to send the location and situation of the car accident. A satellite antenna 21 is installed on the mounting base plate 2 beside the protection box body 1. When the V2X cloud control module in the shielding box 4 is also damaged and the external satellite communication is not controlled by the V2X cloud control module, the external satellite communication (when the V2X cloud control module is not disconnected, it is controlled by the V2X cloud control module and does not start. Once it is out of control, the built-in startup function will send satellite signals) activates the function of sending wireless satellite signals. The shielding box 4 is equipped with a primary backup battery. When the in-vehicle battery cannot supply power, the V2X cloud control module activates the primary backup battery to supply power. The external satellite communication is equipped with a secondary backup battery to independently supply power to the external satellite communication.

[0034] When the emergency communication is damaged and the in-vehicle network cannot be used, and moreover, when the built-in wireless network startup in the V2X cloud control module also fails to achieve information transmission, at this time, the satellite communication is activated. The satellite communication can be used when the in-vehicle network is damaged or not damaged (but the surrounding network signal is poor and wireless connection is impossible), and at the same time, the built-in wireless network cannot be used. Since the satellite communication is installed on the V2X cloud control module, the built-in satellite communication may also fail to work due to the damage of the V2X cloud control module. However, when the entire V2X cloud control module does not work, the external satellite communication will be disconnected from it. At this time, the external satellite communication is activated to work. The shell of the external satellite communication is hard (it is wrapped with steel plates outside, can withstand a large impact force, and will not be damaged under the pressure of 3 tons of gravity), and is not easily damaged. Since it is set outside the shielding box, it will not be affected by signal shielding, and the protection box body 1 does not have a shielding effect, which can ensure the normal operation of the external satellite communication.

[0035] The in-vehicle navigation is capable of reminding in advance whether the road section ahead is congested, under construction, or there has been a traffic accident on the navigation route. The vehicle monitoring module includes a vehicle self-performance monitoring unit, a 360-degree image and radar system. The vehicle self-performance monitoring unit monitors the running status of the vehicle in real time, and the 360-degree image and radar system make judgments on the surrounding obstacles and speed during the vehicle's driving process. The driving situation of the vehicle is judged by analyzing the data collected by the in-vehicle navigation and the vehicle monitoring module, and when a car accident occurs, the cause of the accident is analyzed and sent to the background center through the communication system.

[0036] The vehicle's own performance monitoring unit monitors the vehicle's various performances in real time to determine whether the vehicle is operating normally (including engine or motor, tire pressure and other fault monitoring). 360-degree imaging is a panoramic parking imaging system, which is a parking assistance system that helps car drivers park their vehicles more intuitively, conveniently and safely by viewing 360-degree panoramic fusion, ultra-wide viewing angle and seamless splicing of timely image information around the car through the on-board display screen.

[0037] There are various radar devices, such as ultrasonic radar, millimeter radar, etc., which are set according to the vehicle configuration.

[0038] The roadside equipment includes MEC equipment and OBU equipment. The MEC equipment is installed beside some roads, and the OBU equipment is installed in the middle of the top of the front windshield. The detection of the MEC equipment is the traffic event identified by the algorithm model of the MEC equipment and reported to the cloud control platform. Traffic events include parking, occupying the emergency lane, driving in the wrong direction, pedestrian intrusion, non-motor vehicle intrusion and congestion. When a vehicle enters a road with MEC equipment, the V2X cloud control module will use the vehicle network to obtain the traffic event uploaded by the MEC device. The OBU device is used to detect the vehicle's warning information. The warning information includes forward collision warning, intersection collision warning, emergency braking warning and vehicle loss of control warning, and the warning information is transmitted to the MEC device and reported to the cloud through the MEC device.

[0039] MEC detection events are traffic events identified by the algorithm model of the MEC device and reported to the cloud control platform. They mainly include parking, occupying the emergency lane, driving in the wrong direction, pedestrian intrusion, non-motor vehicle intrusion, congestion and other traffic events. The cloud control platform records information such as the time, location, lane, and event detection equipment of the event.

[0040] OBU warning events are warning information detected by the OBU device of the test vehicle. Events reported to the cloud through MEC include forward collision warning, intersection collision warning, emergency braking warning, vehicle loss of control warning and other warning events. The cloud control platform records the expected time of occurrence, relative position, relative direction angle of the vehicle, recommended type and other information of the warning event.

[0041] Traffic event distribution is to manage the types of simulated events supported by the cloud control system, mainly including two scenarios: V2X traffic events and V2I traffic signs. Users can create traffic event types supported by the cloud control platform in these two scenarios.

[0042] By adding the simulation event function, users can configure different types of event information in V2X or V2I scenarios, and define the start and end time of the simulation event, the location of the event (longitude, latitude), the scope of impact of the event (impact radius, impact area, associated path) and other information in combination with the high-precision map of the test site, and send the event to the corresponding device.

[0043] The API interface provided by the V2X cloud control module (with API interfaces reserved on the side walls of the shielding box 4, and the data line is led out through the large square hole 32 of the foam box cover and the heat dissipation strip hole 11 of the protection box body) is provided externally through the interface service module. The interfaces provided by the cloud control system are registered in the interface service module and provided externally. Alternatively, an interface is set outside the protection box body, but the API interface is connected to the V2X cloud control module inside the shielding box through a data line.

[0044] A storage module is installed in the shielding box 4. The storage module uses Redis as the cache framework. A database is provided in the storage module. The system adopts a database read-write separation mode, with one master and multiple slaves. The master database is only responsible for writing, and the slave databases are only responsible for reading data.

[0045] Redis, as a cache framework and a pure in-memory database, generally involves simple access operations, and the time occupied by threads is relatively long. Redis uses non-blocking IO and IO multiplexing, and uses a single thread to poll and describe.

[0046] The separation mode greatly alleviates the pressure on the master database and distributes most of the read request pressures evenly among multiple slave databases.

[0047] During the vehicle driving process, the driving recorder on the vehicle is data-connected to the V2X cloud control module. The video captured by the driving recorder will be transmitted and backed up to the storage module. When a traffic accident or vehicle failure occurs, the video captured in a period of time (about 10 minutes) before the time point of occurrence will be uploaded to the background.

[0048] Sometimes satellite communication cannot accurately locate, and can only send information. However, the driving recorder can record the road sections captured during the driving process, and use the road sections to upload the captured pictures or videos. The background can search for the approximate location of the accident based on the road section pictures and videos, which can improve the positioning speed (when base station and satellite positioning cannot be used, the road section pictures and videos play an analysis and positioning role).

[0049] The protection box body 1 is a steel frame box body. The wall thickness of the protection box body 1 is 8 - 12 mm. Both the foam box cover 3 and the foam front plug 31 are honeycomb-shaped foam sponges. The foam box cover 3 has a large square hole 32 on each of the left and right side walls and the rear side wall. The foam front plug 31 is evenly provided with ventilation holes. The side wall thickness of the foam box cover 3 and the thickness of the foam front plug are both 20 - 30 mm.

[0050] The steel frame box body has good impact resistance. Since it is installed inside the vehicle, when it is impacted, the vehicle body itself plays a certain protective role, and when the impact force or collision force reaches the steel frame box body, it will be reduced a lot. Coupled with the strong protection of the steel frame box body, it can basically ensure the operation of the internal communication system in most car accident situations for emergency communication. The large square holes 32 can ensure the heat dissipation effect and can also play a good role in supporting the internal shielding box 4. By sealing both sides of the shielding box, heat dissipation and installation of wiring can be carried out.

[0051] Uniform ventilation fine holes are opened on both side walls of the shielding box 4 (the distribution of the ventilation fine holes matches the size of the large square holes 32 on both sides of the foam box cover 3, without blocking the distribution of the ventilation fine holes, but the ventilation fine holes do not affect the shielding of the shielding box). The shielding box 4 is provided with terminal blocks on both side walls. The internal electrical equipment in the shielding box 4 is connected to the inner side of the terminal block through wiring, and the outer side of the terminal block is connected to the vehicle-mounted system through a data line. A cooling fan is provided in the shielding box 4, and the cooling fan can suck the air outside one side wall of the shielding box and discharge it from the other side wall for heat dissipation.

[0052] The wiring can be installed and connected normally and can also dissipate heat normally.

[0053] An equipment software upgrade unit is provided in the shielding box 4. When the equipment software upgrade unit manages the on-vehicle equipment, when an upgrade request is sent by the manufacturer or a user requests an upgrade, it can be upgraded through OTA upgrade management. It meets the system and equipment upgrades to adapt to the update operation of emergency communication.
