[0029] At present, emergency rescue by the police not only wastes police resources, but also requires the police to always pay attention to the location of the vehicle and notify surrounding vehicles to avoid it. Therefore, the existing technology still has the problem of low rescue efficiency.

[0030] To address the low rescue efficiency problem in the existing technology, this application provides an emergency rescue method, which is applied to vehicle-mounted communication equipment. The emergency rescue method provided by this application includes: when a passenger requests help and the road is congested, sending the passenger's physical information to a hospital terminal; receiving confirmation information for the physical information feedback to determine whether the current situation is urgent; if the current situation is urgent, sending the confirmation information to surrounding vehicles, so that the surrounding vehicles send their location information to this terminal after verifying the confirmation information; planning a rescue channel, and notifying each vehicle on the rescue channel to avoid the situation based on the location information.

[0031] In order to better understand the emergency rescue method provided by this application, this application provides an embodiment, such as Figure 1 Next, this application will take the vehicle-mounted communication equipment as the execution subject and Figure 1 The emergency rescue method described is explained. Specifically:

[0032] 101: When a passenger asks for help and the road is congested, the passenger's physical information will be sent to the hospital terminal.

[0033] Among them, the vehicle-mounted communication equipment can send the passenger's physical information to the hospital terminal when the passenger asks for help and the road is congested, so that the hospital can obtain confirmation information by analyzing the physical information, and the confirmation information is used to indicate whether the current situation is urgent.

[0034] It should be noted that physical information includes at least one of the following: condition description information, condition monitoring information and pre-stored condition information. The condition description information is the passenger's description of his or her condition, such as heart pain, etc. The pre-stored condition information includes at least one of the vehicle information, owner information, emergency contact person and medical history. The condition monitoring information includes at least one of the heart rate, blood pressure, blood sugar and pulse rate.

[0035] It should also be noted that the vehicle-mounted communication device can detect whether a passenger is requesting help through the rescue activation device, and can also obtain the passenger's physical information through the rescue activation device. In addition, the autonomous driving device can determine whether the road to the hospital is congested. The rescue activation device is used to monitor the passenger's call for help and generate the passenger's physical information. The autonomous driving device is used to determine the hospital and determine whether the road to the hospital is congested based on the physical information. The hospital terminal is used to determine whether the current situation is urgent based on the physical information.

[0036] 102: Receive confirmation information for the body information feedback to determine whether the current situation is urgent.

[0037] After receiving the confirmation information sent by the hospital terminal, the on-board communication device can directly determine whether the current situation is urgent based on the confirmation result in the confirmation information, or it can first verify the confirmation information and then determine whether the current situation is urgent based on the confirmation result in the confirmation information. For example, if the confirmation result is "yes", it indicates that the current situation is urgent, and if the confirmation result is "no", it indicates that the current situation is not urgent. In addition to the confirmation result, the confirmation information may also include at least one of a hash algorithm, a hospital identifier, a signature portion, a purpose, and a validity period.

[0038] 103: If the current situation is urgent, confirmation information is sent to surrounding vehicles, so that the surrounding vehicles send their location information to the local end after verifying the confirmation information.

[0039] Among them, if the on-board communication device confirms that the current situation is urgent, it will send the confirmation information generated by the hospital terminal to the surrounding vehicles, so that the surrounding vehicles will send the location information of the surrounding vehicles to this end after verifying the confirmation information. The verification method includes at least one of hash calculation and hospital public key decryption. It should be noted that the surrounding vehicles refer to vehicles that can communicate with the on-board communication device of this end through wireless short-range communication, that is, vehicles within the wireless short-range communication range, and as the vehicle travels, the surrounding vehicles also change with the change of the communication range. The short-range communication method can be WiFi, Mesh, Bluetooth, ZigBee, Thread, Z-Wave, NFC, UWB or LiFi, etc., and this application does not limit this.

[0040] It should be noted that the confirmation information may include the confirmation result after encryption using the hospital private key, and the confirmation information is obtained by the hospital terminal through a layer of encryption. It can be known that the hospital private key and the hospital public key are a pair of keys obtained through an encryption algorithm, which are asymmetric. The data encrypted using the hospital private key can only be decrypted by the hospital public key. Therefore, when the on-board communication device at this end and the surrounding vehicles receive the confirmation information, the confirmation information can be decrypted using the hospital public key. While obtaining the confirmation result in the confirmation information, the authenticity of the confirmation information can be verified. The hospital public keys in the on-board communication device at this end and the surrounding vehicles can be pre-stored in the local database, or obtained through two-way authentication with the hospital terminal. This application does not limit this.

[0041] It should also be noted that the confirmation information may also include a file part and a signature part. The file part includes the confirmation result, hospital identification and hash algorithm. The data structure of the confirmation information may be as follows: Figure 2 As shown. The confirmation result is used to indicate whether the current situation is urgent, the hospital identification is used to indicate the hospital terminal from which the confirmation information comes, and the signature part is used to indicate whether the verification confirmation information is credible. The confirmation information is obtained by the hospital terminal through two layers of encryption. Next, this application will explain the two layers of encryption on the confirmation information: the signature part in the confirmation information is obtained by successively performing hash calculation on the file part and encrypting it with the hospital private key. Specifically, after the hospital terminal combines the confirmation result, the hospital identification and the hash algorithm to obtain the file part, it uses the hash algorithm to calculate the file part to obtain a first character string, and then uses the hospital private key to encrypt the first character string to obtain the signature part, and finally combines the signature part and the file part to obtain the confirmation information. After the on-board communication device of this end and the surrounding vehicles receive the confirmation information, while reading the confirmation result in the confirmation information, they can also use the signature part to verify the authenticity of the confirmation information. The verification process will be described in detail later.

[0042] 104: Plan a rescue channel and notify each vehicle on the rescue channel to give way based on the location information.

[0043] Among them, the on-board communication equipment plans a rescue channel, and after receiving the position information of the surrounding vehicles, it screens out the vehicles on the rescue channel and notifies the vehicles on the rescue channel to avoid. It should be noted that the aforementioned planned rescue channel can be the lane where the vehicle is currently traveling as the rescue channel, or the lane to be changed as the rescue channel, and this application does not limit this. In order to determine the lane that the car on this end is about to change, the on-board communication equipment can determine it based on the road to the hospital navigated by the automatic driving equipment.

[0044] In summary, when a passenger asks for help and the road is congested, the vehicle-mounted communication equipment of the present application sends the passenger's physical information to the hospital terminal, which confirms whether the current situation is urgent. After receiving the confirmation information and determining that the current situation is urgent based on the confirmation information, the terminal sends the confirmation information to the surrounding vehicles, thereby gaining the trust of the surrounding vehicles and the location information of the surrounding vehicles. Finally, a rescue channel is planned, and each vehicle on the rescue channel is determined based on the location information of the surrounding vehicles, and each vehicle on the rescue channel is notified to avoid the rescue channel to achieve emergency rescue. It can be seen that the emergency rescue of the present application can improve the efficiency of emergency rescue under the premise of ensuring safety, and improve the problem of low rescue efficiency in the existing technology.

[0045] For step 102, in order to further improve security, the present application also provides an implementable method, wherein the above-mentioned confirmation information includes a file part and a signature part, and the file part includes a confirmation result, a hospital identifier and a hash algorithm; the above-mentioned step of receiving confirmation information for physical information feedback to determine whether the current situation is urgent includes: after receiving the confirmation information, obtaining the corresponding hospital terminal and hospital public key according to the hospital identifier; using the hospital public key to decrypt the signature part, if the decryption is successful, it is determined that the confirmation information comes from the hospital terminal, and the first decrypted character string is obtained; the file part is calculated according to the hash algorithm to obtain a second character string; compare the first character string and the second character string to see if they are consistent, if the strings are consistent, it is determined that the confirmation information has not been tampered with, and if the confirmation result is yes, it is confirmed that the current situation is urgent.

[0046] In this possible implementation mode, the confirmation information is obtained through the aforementioned two-layer encryption. After receiving the two-layer encrypted confirmation information, the on-board communication device first verifies the confirmation information using the signature part in the confirmation information to verify whether the confirmation information comes from the hospital terminal indicated by the hospital logo and has not been tampered with. If the verification is passed, the confirmation result in the confirmation information is read to see if it is yes. If the confirmation result is yes, it is confirmed that the current situation is urgent.

[0047] The aforementioned verification process includes two steps: one is to determine whether the confirmation information comes from the hospital terminal indicated by the hospital logo, and the other is to determine whether the confirmation information has not been tampered with. Specifically:

[0048] The first step is to determine whether the confirmation information comes from the hospital terminal indicated by the hospital logo: After receiving the confirmation information, the on-board communication equipment obtains the corresponding hospital terminal and hospital public key according to the hospital logo, and uses the hospital public key to decrypt the signature part. If the decryption is successful, it is determined that the confirmation information comes from the hospital terminal indicated by the hospital logo. If the decryption fails, it is determined that the confirmation information does not come from the hospital terminal indicated by the hospital logo. At this time, the confirmation information is discarded, and an attempt is made to obtain confirmation information from the hospital terminal by sending the physical information to the hospital terminal again.

[0049] Step 2: Determine whether the confirmation information has not been tampered with: After successfully decrypting the signature part using the hospital public key, obtain the first character string obtained after the decryption, and use the hash algorithm of the file part to hash the file part to obtain the second character string. By comparing the first character string and the second character string, it can be determined whether the confirmation information has been tampered with. If they are consistent, it means that it has not been tampered with. If they are inconsistent, it means that it has been tampered with. At this time, discard the confirmation information and try to obtain confirmation information from the hospital terminal by sending the physical information to the hospital terminal again.

[0050] It should be noted that the above verification process can be executed by the vehicle-mounted communication device at the local end or by surrounding vehicles to verify the authenticity of the confirmation information.

[0051] For step 104, in order to further improve the efficiency of rescue, the present application also provides an implementable method. The above-mentioned steps of planning a rescue channel and notifying each vehicle on the rescue channel to avoid according to the position information include: using the lane in which the vehicle is currently traveling or the lane to be changed as the rescue channel, and after receiving the position information, determining the vehicle on the rescue channel according to the position information; planning a lane change plan for the vehicles on the rescue channel, and sending the corresponding lane change plan to each vehicle on the rescue channel, so that each vehicle on the rescue channel changes lanes according to the corresponding lane change plan.

[0052] In this embodiment, after the onboard communication device has mapped out a rescue lane and identified each vehicle in the rescue lane based on the location information of surrounding vehicles, it plans a lane change plan for each vehicle in the rescue lane and transmits the corresponding lane change plan to each vehicle in the rescue lane. This ensures that each vehicle changes lanes according to the corresponding lane change plan, thereby reducing the chance of collision with other vehicles and creating a clear rescue lane. The autonomous driving device in the vehicle terminal can activate the driving module to quickly pass through the rescue lane without driver input, thereby achieving emergency rescue.

[0053] In order to specifically illustrate the emergency rescue method provided by this application, this application also provides an embodiment, such as Figure 3 Next, this application will take the vehicle-mounted communication equipment as the execution subject and Figure 3 The emergency rescue method described is explained. Specifically:

[0054] 301: When a passenger asks for help and the road is congested, the passenger's physical information is sent to the hospital terminal.

[0055] Among them, the physical information includes a file part and a signature part, and the file part includes confirmation results, hospital identification and hash algorithm.

[0056] 302: Receive confirmation information for the body information feedback, and after verifying the confirmation information, determine whether the current situation is urgent based on the confirmation information.

[0057] Among them, after receiving the confirmation information fed back by the hospital terminal regarding the physical information, the on-board communication equipment first verifies the authenticity of the confirmation information using the signature part in the confirmation information. After the verification is passed, it determines whether the current situation is urgent based on the confirmation result in the confirmation information.

[0058] 303: Send confirmation information to surrounding vehicles, so that the surrounding vehicles send location information of the surrounding vehicles to the local end after verifying the confirmation information.

[0059] Among them, after determining whether the current situation is urgent, the on-board communication equipment sends confirmation information to the surrounding vehicles, so that the surrounding vehicles can also use the signature part in the confirmation information to verify the authenticity of the confirmation information. After the verification is passed, it is determined whether the current situation is urgent based on the confirmation result in the confirmation information. If the verification is passed and the current situation is urgent, the location information is sent to the on-board communication equipment on this end.

[0060] 304: Determine the vehicle on the rescue channel based on the received position information, plan a lane change plan for the vehicle on the rescue channel, and send the corresponding lane change plan to the vehicle on the rescue channel so that the vehicle on the rescue channel changes lanes according to the corresponding lane change plan.

[0061] In summary, after receiving the confirmation information from the hospital terminal, the vehicle-mounted communication device of the present application verifies the authenticity of the confirmation information and also sends the confirmation information to surrounding vehicles, so that the surrounding vehicles also verify the authenticity of the confirmation information. It can be seen that the embodiment of the present application improves safety and further improves the efficiency of rescue by performing double verification of the rescue process.

[0063] Among them, the rescue starting device 412 is used to obtain physical information and determine whether the passenger's physical body is abnormal based on the physical information. If it is determined that the passenger's physical body is abnormal, the physical abnormality flag is sent to the automatic driving device, and the physical abnormality flag and physical information are sent to the on-board communication device, so that when the on-board communication device reads the physical abnormality flag, it is determined that the passenger's physical body is abnormal.
