The specific form of the alarm information can be various, for example, the alarm information can be sound and light information sent by the unmanned vehicle, such as a whistle, a lighting device and the like. In addition, when the state of the other vehicle is abnormal, the current vehicle can also take certain anti-theft measures. The anti-theft measures may include: and starting a camera of the current vehicle to shoot the surrounding environment so as to acquire images of the performer aiming at the illegal behaviors.
The following describes in detail a warning method for a vehicle described in this specification.
As shown in fig. 2, in this specification, the network architecture includes a plurality of vehicles, any one of the vehicles may be a current vehicle in this specification, and any vehicle other than the current vehicle may be another vehicle in this specification. Each vehicle accesses the same network and can communicate via the network. Each vehicle in the vehicles accessing the network can be used as a current vehicle in the specification; each of the vehicles connected to the network may be another vehicle in this specification. As shown in fig. 3, the current vehicle can receive a status message of at least one other vehicle in the network to supervise the status of the other vehicle, and the other vehicle supervised by the current vehicle is the first target vehicle of the current vehicle. And the current vehicle can also send the state message of the current vehicle to at least one other vehicle in the network, so that the at least one other vehicle can supervise the state of the current vehicle, and the other vehicle for supervising the current vehicle is the second target vehicle of the current vehicle.
In this specification, before determining at least one other vehicle than the current vehicle in the network in which the current vehicle is located, the method further includes: it is determined whether the current vehicle is within the coverage of a network established by other vehicles. If yes, the current vehicle accesses the network; and otherwise, establishing a network, wherein the network is used for being accessed by other vehicles, so that each vehicle accessed to the network communicates through the network.
Wherein the network for communication between the vehicles may be established by one of the vehicles. For example, each vehicle is provided with a Dedicated Short Range Communication (DSRC) device for establishing the network, by which a network accessible to other vehicles can be established. The network may be a local area network with a certain coverage area. The DSRC apparatus may be provided in a vehicle-mounted device of a vehicle.
By the method in the embodiment of the present specification, the current vehicle may first determine the network environment where it is located to determine whether a network needs to be established or joined. It can be seen that the method in the embodiments of the present description is not limited by the geographical location of the network coverage. If the current vehicle exits the coverage area of a network established by another vehicle (i.e., the geographic location of the current vehicle has changed), the current vehicle may re-detect whether it is within the coverage area of a network established by another other vehicle or establish a network via its own DSRC device.
When the current vehicle establishes a network by its own DSRC device, an identification corresponding to the network is set for the network, and the identification may include the aforementioned time authentication information of the network and/or dynamic authentication information of the network.
The time verification information of the network may be obtained by a Global Positioning System (GPS) clock, and the time verification information of the network conforming to the protocol is output according to a preset time verification information rule of a vehicle that establishes the network. The time verification information may be used to unify system times employed by vehicles accessing the network, and may also be used to characterize network accessible time periods. For example, the time verification information for the network is 090000 and 210000, then the vehicle may access the network during the time period between 9:00 and 21: 00.
The dynamic authentication information of the network may be a set of random numbers corresponding to the network generated by the vehicle when the network is established, and the dynamic authentication information of the network may serve as an identifier of the network. Optionally, the dynamic authentication information of the network remains unchanged for a period of time of the temporal authentication information specification. The dynamic authentication information is regenerated when the vehicle reestablishes the network.
When the other vehicle joins the network, the time verification information of the network and/or the dynamic verification information of the network are/is acquired first, and the time verification information and/or the dynamic verification information of the network acquired first time are/is used as a part of the standard state information of the other vehicle. Then, when the other vehicle generates the state message each time, the first time of obtaining the time verification information and/or the dynamic verification information of the network is used as a part of the state message of the other vehicle; or, when the other vehicle generates the status message each time, the time verification information and/or the dynamic verification information of the network are/is acquired again, and the acquired time verification information and/or the dynamic verification information of the network are/is used as a part of the status message of the other vehicle.
The operation of the current vehicle to determine the network environment in which it is located may be triggered in a number of ways. For example, the network environment in which the current vehicle is located may be automatically determined under the control of the control system of the vehicle after the current vehicle is parked; as another example, the triggering may be by way of manual control.
When the method of the specification is adopted, when the communication between the vehicles accessing the network is realized by the network established by the vehicles, the serial number rule corresponding to the network is adopted to set the corresponding serial numbers for the vehicles accessing the network. Wherein the serial number rule may be used to uniquely identify each vehicle accessing the network.
Further, the sequence numbers determined according to the sequence number rule may have a certain order. For example, if the serial number determined for the vehicle that establishes the network is 0 (i.e., the first serial number), and for each vehicle that subsequently joins the network, the serial number of the vehicle is determined in the order in which the vehicle joins, then the serial number of the 16 th vehicle that joins the network is 16. Then, by the method in this specification, each time a vehicle accesses a network, the last serial number in the network may be determined first, and the next serial number to the last serial number may be used as the serial number of the vehicle accessing the network.
And when the current vehicle accesses the network, firstly, determining the serial number of the current vehicle in the network according to a preset serial number rule of the network. And then, according to the serial number of the current vehicle in the network, determining standard state information of the current vehicle as a self state message of the current vehicle which is sent in the network for the first time (the self state message which is sent in the first time contains the serial number of the current vehicle). Then, the status message of the current vehicle is sent to at least one other vehicle in the network to inform the at least one other vehicle of the serial number of the current vehicle.
In addition, the serial number rule can also be used for establishing a certain corresponding relationship among the determined serial numbers, so that a corresponding relationship is established among the vehicles corresponding to the serial numbers according to the corresponding relationship among the serial numbers. And then aiming at each vehicle accessed to the network, according to the serial number and the serial number rule of each vehicle, the first target vehicle and the second target vehicle corresponding to the vehicle can be determined.
For example, as shown in fig. 3, after the current vehicle accesses the network, at least one first serial number may be determined from the serial numbers of the vehicles in the network according to the serial number of the current vehicle and a serial number rule, and another vehicle corresponding to the first serial number may be used as the first target vehicle corresponding to the current vehicle.
Specifically, the first target vehicle may be determined for the current vehicle based on the order between the serial numbers of the vehicles in the network. For example, it may be determined that a serial number (or previous serial numbers) before the serial number of the current vehicle is a first serial number, and the other vehicles corresponding to the first serial numbers are used as the first target vehicles of the current vehicle. If the serial number of the current vehicle is 16, the first serial number of the current vehicle is 15 (or the first serial numbers are 10 to 15), and the other vehicles with the serial numbers of 15 (or the other vehicles with the serial numbers of 10 to 15) are the first target vehicles of the current vehicle.
In this specification, when the current vehicle accesses the network, it is necessary to determine the standard state information of at least one other vehicle, so that the current vehicle can determine the state of the other vehicle according to the standard state information of the other vehicle and the state message of the other vehicle. The current vehicle may determine, for at least one of the other vehicles, that the current vehicle first receives, in the network, information included in a status message sent by the other vehicle, as standard status information of the other vehicle.
For example, after the current vehicle determines the corresponding first target vehicle, information included in a status message sent by the first target vehicle is received for the first time as standard status information of the first target vehicle.
In addition, the current vehicle accesses the network and needs to send its own standard state information to at least one other vehicle, so that the other vehicle can determine the state of the current vehicle according to the standard state information of the current vehicle.
For example, as shown in fig. 3, the current vehicle may determine at least one second serial number from the serial numbers of the vehicles in the network according to its own serial number and a serial number rule, and use the vehicle corresponding to the second serial number as the second target vehicle. Then, the current vehicle transmits its own status message, which is transmitted for the first time, to the second target vehicle. And then, the current vehicle still sends the state message of the current vehicle to the second target vehicle, and the second target vehicle is used as the vehicle for receiving the state message of the current vehicle, so that the second target vehicle can determine whether the state of the current vehicle is normal or not according to the state message of the current vehicle and the stored standard state information of the current vehicle.
Or, the current vehicle sends its own status message sent for the first time to each vehicle in the network in a broadcast manner, and then the other vehicle that receives the status message sent for the first time may determine whether to store the standard status information in the status message sent for the first time according to the serial number of the current vehicle, the serial number of the other vehicle, and the serial number rule recorded in the status message sent for the first time. If the serial number of the other vehicle and the serial number of the current vehicle meet the serial number rule (that is, the serial number of the other vehicle is the second serial number corresponding to the serial number of the current vehicle in the serial number rule), the other vehicle stores the standard state information in the first-sent state message.
Or, the current vehicle only sends the self state message sent for the first time to other vehicles establishing the network. And determining at least one second serial number in the serial numbers of all vehicles in the network by other vehicles establishing the network according to the serial number rule and the serial number of the current vehicle, taking the vehicle corresponding to the second serial number as a second target vehicle, and sending the self state message sent by the current vehicle for the first time to the second target vehicle.
When determining the second target vehicle corresponding to the current vehicle, the second target vehicle of the current vehicle may be determined according to the order between the serial numbers of the vehicles in the network. For example, it may be determined that the next (or last) serial number of the serial numbers of the current vehicle is the second serial number, and the other vehicles corresponding to the second serial numbers are the second target vehicle of the current vehicle. If the serial number of the current vehicle is 16, the second serial number of the current vehicle is 17 (or the first serial number is 17 to 21), and the other vehicles with the serial numbers of 17 (or the other vehicles with the serial numbers of 17 to 21) are the second target vehicles of the current vehicle.
As shown in fig. 4, if the serial number of the current vehicle is the last serial number in the network, the second target vehicle of the current vehicle is the vehicle corresponding to the first serial number in the network. And if the serial number of the current vehicle is the first serial number in the network, the first target vehicle of the current vehicle is the vehicle corresponding to the last serial number in the network.
For example, the other vehicle corresponding to the previous serial number of the current vehicle is determined as the first target vehicle of the current vehicle, and the other vehicle corresponding to the next serial number of the current vehicle is determined as the second target vehicle of the current vehicle. And each vehicle accessing the network stores the standard state information of the corresponding first target vehicle and determines the state of the corresponding first target vehicle. And determining the state of the current vehicle by the second target vehicle corresponding to the current vehicle, so that the vehicles in the network are arranged in a ring shape according to the sequence of the serial numbers of the vehicles.
In this specification, the status message may further include: information characterizing a connection status of the vehicle to the network. If the state message of the first target vehicle received by the current vehicle contains exit notification information that another vehicle in the network exits the network, the exit notification information is carried in the state message of the current vehicle and is sent to the second target vehicle, so as to notify the exit of the other vehicle in the network of the second target vehicle. The exit notification information may include the serial numbers of other vehicles that exit the network.
In this way, each vehicle in the network sends the state message of the vehicle to the second target vehicle corresponding to the vehicle, and the vehicle carries the exit notification information, so that each vehicle in the network can acquire the serial numbers of other vehicles exiting the network.
Due to the exit of the other vehicle, the current serial number of at least some vehicles in the network no longer complies with the serial number rule, and at least some vehicles that remain connected to the network (e.g., the at least some vehicles may be other vehicles with serial numbers greater than the serial number of the vehicle exiting the network) need to re-determine their own serial numbers.
And after the current vehicle carries the exit notification information in a state message of the current vehicle and sends the exit notification information to a second target vehicle, the current vehicle re-determines the serial number of the current vehicle according to the exit notification information and the serial number rule. And after the self serial number is determined again, the current vehicle determines the first target vehicle and the second target vehicle again according to the re-determined self serial number of the current vehicle and the serial number rule.
For example, the serial number of the current vehicle is 16, the serial number of the first target vehicle corresponding to the current vehicle is 15, and the status message of the first target vehicle includes exit notification information that the first target vehicle exits the network. In order to meet the serial number specification, the current vehicle changes its own serial number to the serial number of the first target vehicle corresponding to the current vehicle, that is, the current vehicle changes its own serial number to 15. And, the other vehicle with the serial number of 14 is newly determined as the first target vehicle of the current vehicle.
In addition, the status message received by the current vehicle includes exit notification information that another vehicle in the network exits the network, and first, according to the serial number and the serial number rule of the other vehicle exiting the network in the exit notification information, it is determined whether the current vehicle needs to change its own serial number, whether the first target vehicle needs to be re-determined, and whether the second target vehicle needs to be re-determined. For example, if the serial number of the other vehicle exiting the network is greater than the second serial number of the current vehicle, the current vehicle does not need to re-determine its own serial number, the first target vehicle, and the second target vehicle. If the serial numbers of the other vehicles exiting the network are smaller than the first serial number of the current vehicle, the current vehicle needs to determine the serial number of the current vehicle, the first target vehicle and the second target vehicle again.
Optionally, the current vehicle that receives the status message may determine whether the other vehicle that sends the status message is the first target vehicle of the current vehicle according to the information of the connection status between the other vehicle and the network recorded in the status message.
For example, if the status message received by the current vehicle includes an addition notification message that another vehicle will be added to the network, it indicates that the status message is a status message that the other vehicle first sends in the network, and the status message records standard status information of the other vehicle, and the current vehicle should record the standard status information in the status message. The join notification information may be a character of a preset field recorded in the status message, for example, if the character in the preset field of the standard status message is 01, it indicates that the vehicle sending the status message has just joined the network. In the scenario where the vehicle sending the status message will continue to maintain a connection to the network, the character is 02. In a scenario where the vehicle that sent the status message will exit the network, the character is 03 (corresponding to exit notification information described below).
In this specification, the status message may further include: and (4) exception notification information. The abnormality notification information may be used to characterize an abnormal state of a vehicle in the network (the abnormal state may be caused by a lawless act on the vehicle), and to instruct the vehicle that receives the abnormality notification information to issue warning information.
For example, if the state of the first target vehicle corresponding to the current vehicle is abnormal, the current vehicle sends alarm information according to the abnormal state of the first target vehicle, and determines the abnormal notification information for the first target vehicle. And then, the current vehicle carries the abnormal notification information in a state message of the current vehicle and sends the abnormal notification information to the second target vehicle, so that the second target vehicle determines the state of the current vehicle according to the state message of the current vehicle and sends alarm information according to the abnormal notification information carried in the state message of the current vehicle. And then, the second target vehicle determines a state message of the second target vehicle according to the state of the second target vehicle and the abnormal notification information, and sends the state message to the vehicle which is required to receive the state message in the serial number rule, so that the vehicle sends alarm information. By analogy, all vehicles accessed into the network can send alarm information.
Alternatively, the abnormality notification information may include a serial number of the vehicle in which the state is abnormal. If the state message received by the vehicle includes the abnormal notification information, the current vehicle re-determines the serial number of the current vehicle according to the serial number of the vehicle with the abnormal state included in the abnormal notification information. And then, the current vehicle determines a state message of the current vehicle according to the re-determined serial number of the current vehicle and the abnormal notification information, and sends the state message to a second target vehicle corresponding to the current vehicle, so that the second target vehicle re-determines the serial number of the second target vehicle according to the state message of the current vehicle and a preset serial number rule. That is, the method of changing the serial number of the vehicle by the abnormality notification information is the same as the method of changing the serial number of the vehicle by the exit notification information. Then, by the method in this specification, when a vehicle is abnormal, each other vehicle in the network, in addition to sending out the alarm information for the abnormal vehicle, considers that the abnormal vehicle has exited the network, and re-determines the serial number of at least a part of the vehicles in the network, so that the vehicles in the normal state in the network can continue to supervise each other's state.
In this specification, each vehicle accessing the network may be in communication connection with the backend server, and the backend server may store standard state information of each vehicle. Each vehicle can send the state message to the background server, and the background server determines the state of each vehicle in the network according to the standard state information of each vehicle stored in the background server and the state message sent by each vehicle.

The embodiment of the present specification also provides a computer readable storage medium, which stores a computer program, and the computer program can be used for executing the process of alarming the vehicle provided by the above-mentioned fig. 1.
The embodiment of the present specification also provides a schematic structural diagram of the electronic device shown in fig. 6. As shown in fig. 6, at the hardware level, the electronic device includes a processor, an internal bus, a network interface, a memory, and a non-volatile memory, but may also include hardware required for other services. The processor reads a corresponding computer program from the non-volatile memory into the memory and then runs the computer program to implement the process of controlling the unmanned vehicle as described above with reference to fig. 1. Of course, besides the software implementation, the present specification does not exclude other implementations, such as logic devices or a combination of software and hardware, and the like, that is, the execution subject of the following processing flow is not limited to each logic unit, and may be hardware or logic devices.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardsradware (Hardware Description Language), vhjhd (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
