[0060] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0061] In an exemplary embodiment, Figure 1As shown, a disaster alarm data processing system 10 is provided. The disaster alarm data processing system 10 includes a cell broadcast entity 11 (Cell Broadcast Entity, referred to as CBE), a cell broadcast center 12 (Cell Broadcast Center, referred to as CBC), a base station 14 control center 13 and a base station 14. The cell broadcast entity 11 is connected to the disaster sensor signal and is also connected to the cell broadcast center 12 signal. The cell broadcast center 12 is connected to the base station 14 control center 13 signal. The base station 14 control center 13 is connected to the base station 14 signal.

[0062] The cell broadcast entity 11 is used to obtain disaster alarm data transmitted by the disaster sensor and send the disaster alarm data to the cell broadcast center 12 .

[0063] The disaster sensor includes at least one of a geological disaster sensor, a bridge sensor, a tunnel sensor or a road sensor; the disaster alarm data is sent when the disaster sensor determines that the collected data meets the alarm condition.

[0064] Among them, geological disaster sensors are devices used to monitor and warn of geological disasters. They can collect geological environment data in real time and predict and warn possible geological disasters by analyzing these data. Geological disaster sensors can include one or more of the following: earthquake sensors, landslide sensors, debris flow sensors, water level sensors, and rainfall sensors.

[0065] Among them, bridge sensors are used for monitoring the health of bridge structures. Bridge sensors can include one or more of the following: stress and strain sensors, displacement sensors, vibration sensors, environmental sensors, etc.

[0066] Among them, the tunnel sensor is used to monitor the internal environment and structural status of the tunnel. The tunnel sensor may include one or more of the following types: visibility sensor, temperature sensor, oxygen sensor, smoke sensor, tilt sensor, strain sensor, water level sensor, etc.

[0067] Among them, the road sensors related to driving safety are mainly road condition sensors, which can monitor the status of the road surface in real time, such as the degree of wetness, icing conditions, water depth, etc.

[0068] According to the above tests and experience summarization of the impact of various disaster sensors on driving safety, the sensor monitoring and early warning system can set alarm conditions for each disaster sensor. If the data collected by the disaster sensor reaches the alarm condition, the disaster sensor sends the disaster alarm data to the cell broadcast entity 11. The alarm condition can be to alarm after reaching the alarm threshold. If the data collected by the disaster sensor reaches the alarm threshold, the disaster sensor sends the disaster alarm data to the cell broadcast entity 11.

[0069] The disaster alarm data includes data collected by disaster sensors and may also include a disaster alarm prompt field.

[0070] The cell broadcast entity 11 provides access services, collects disaster warning data that needs to be broadcast, and then transmits the disaster warning data to the cell broadcast center 12 .

[0071] The cell broadcast center 12 is connected to the mobile communication network and sends disaster alarm data to the mobile communication network. Optionally, the cell broadcast center 12 is connected to the mobile communication network according to the 3GPP (Third Generation Partnership Project) cell broadcast protocol. The cell broadcast center 12 encodes the disaster alarm data from the cell broadcast entity 11 according to the 3GPP cell broadcast protocol. The cell broadcast center 12 is used to parse and encode the disaster alarm data, and then send the encoded disaster alarm data to the base station 14 control center 13 of the mobile communication network.

[0072] Optionally, the cell broadcast system (including the cell broadcast entity 11 and the cell broadcast center 12) adopts CMAS (full name Commercial Mobile Alert System) technology that complies with 3GPP 23.041 international specifications.

[0073] The base station 14 control center 13 is used to send the processed disaster alarm data to the base station 14 corresponding to the disaster area. The base station 14 control center 13 is used to perform necessary processing on the disaster alarm data, such as format conversion, encryption, decryption, compression, decompression, etc., to ensure that the disaster alarm data can be correctly transmitted in the mobile communication network. Specifically, the base station 14 control center 13 is used to select the best routing path according to the destination of the disaster alarm data and the topological structure of the mobile communication network. The base station 14 control center 13 is also used to determine the location and identification of the target base station 14 so as to send the disaster alarm data to the correct base station 14. In this embodiment, the base station 14 control center 13 is used to send the disaster alarm data to the base station 14 corresponding to the disaster area. The base station 14 control center 13 is also used to send the processed disaster alarm data to the target base station 14 through the data channel of the mobile communication network. During the transmission of the disaster alarm data, the base station 14 control center 13 will monitor the transmission status of the disaster alarm data to ensure the integrity and reliability of the disaster alarm data.

[0074] The base station 14 corresponding to the disaster area is used to send the encoded disaster alarm data to the car terminal 15. The communication system of the car terminal 15 is provided with a mobile communication chip 151, which supports public mobile communication network communication. The public mobile communication network includes 3G (full name 3rd Generation Mobile Communication Technology), 4G (full name 4th Generation Mobile Communication Technology) and 5G (full name 5th Generation Mobile Communication Technology). The base station 14 sends the encoded disaster alarm data to the mobile communication chip 151. After receiving the disaster alarm data, the car terminal 15 can promptly remind the driver that a disaster has occurred, thereby helping the driver avoid the disaster area and improving driving safety.

[0075] The disaster alarm data processing system provided in this embodiment can quickly send disaster alarm data related to driving safety to the car terminal 15 around the disaster site through the mobile communication network cell broadcast system, and support the car terminal 15 to automatically control the vehicle according to the disaster alarm data to avoid accidents. Compared with the traditional solution, the disaster alarm data processing system provided in this embodiment can send disaster alarm data that affects driving safety to the car terminal 15 in a timely manner, so as to avoid similar major traffic accidents to the greatest extent and improve driving safety.

[0076] In an exemplary embodiment, the cell broadcast entity 11 is used to send disaster alarm data to the cell broadcast center 12, specifically, when it is determined that the disaster level corresponding to the disaster alarm data is an alarm level, the disaster alarm data is sent to the cell broadcast center 12 in real time. When it is determined that the disaster level corresponding to the disaster alarm data is a non-alarm level, if the audit pass operation of the disaster alarm data is detected, the disaster alarm data is sent to the cell broadcast center 12.

[0077] The cell broadcast entity 11 may set review rules so that disaster alarm data of the alarm level (which may also be understood as a higher level) can be sent to the cell broadcast center 12 without manual review, while disaster alarm data of the non-alarm level (which may also be understood as a lower level) may be sent to the cell broadcast center 12 after manual review or not sent. Correspondingly, when it is determined that the disaster level corresponding to the disaster alarm data is the alarm level, the disaster alarm data is sent in real time (immediately) to the cell broadcast center 12. When it is determined that the disaster level corresponding to the disaster alarm data is the non-alarm level, if the audit pass operation of the disaster alarm data is detected, the disaster alarm data is sent to the cell broadcast center 12.

[0078] The audit pass operation is performed by the staff to verify the disaster alarm data and generate the data after confirming that the disaster alarm data is correct. The audit pass operation may also include the staff modifying the disaster alarm data. Correspondingly, after the disaster alarm data is modified according to the operation of modifying the disaster alarm data, the modified disaster alarm data is sent to the community broadcast center 12. The accuracy of the disaster alarm data can be improved by the staff performing audit and modification operations on the disaster alarm data.

[0079] Among them, the alarm level can be understood as the level corresponding to when the disaster alarm data is greater than or equal to the early warning disaster alarm data, and the non-alarm level can be understood as the level corresponding to when the disaster alarm data is less than the early warning disaster alarm data. The non-alarm level can also be divided into multiple sub-levels, and different sub-levels correspond to different manual review rules. For example, the manual review rules corresponding to higher levels are simpler, such as only one manual review is required to pass the review. For example, the manual review rules corresponding to lower levels are more complex, such as multiple audits and confirmations are required before the review can be passed.

[0080] Optionally, different disaster sensors correspond to different early warning disaster alarm data, for example, bridge sensors correspond to the first early warning disaster data, geological disaster sensors correspond to the second early warning disaster data, tunnel sensors correspond to the third early warning disaster data, and road sensors correspond to the fourth early warning disaster data. Optionally, different early warning disaster alarm data can be set for different driving scenarios. For example, if the driving scenario is mostly on bridges, the first early warning disaster alarm data corresponding to the bridge sensor is lower to enhance the monitoring of bridges.

[0081] Optionally, the data collected by multiple different disaster sensors can be calculated as one data, and then the one data can be compared with the early warning disaster data. In the case that the one data is greater than or equal to the early warning disaster data, the one data can be sent to the cell broadcast center 12 without manual review. In the case that the one data is less than the early warning disaster data, if the review of the disaster alarm data is detected, the disaster alarm data is sent to the cell broadcast center 12.

[0082] The disaster alarm data processing system provided in this embodiment can quickly send disaster alarm data related to driving safety to the car terminal 15 around the disaster site through the mobile communication network cell broadcast system when the disaster level corresponding to the disaster alarm data is the alarm level, and support the car terminal 15 to automatically control the vehicle according to the disaster alarm data to avoid accidents. Compared with the traditional solution, the disaster alarm data processing system provided in this embodiment can send disaster alarm data that affects driving safety to the car terminal 15 in a timely manner, so as to avoid similar major traffic accidents to the greatest extent and improve driving safety.

[0083] In addition, when the disaster level corresponding to the disaster alarm data is a non-alarm level, the disaster alarm data is sent to the cell broadcast center 12 only after the audit pass operation of the disaster alarm data is detected. This is to improve the accuracy of the disaster alarm data and avoid false alarms.

[0084] In an exemplary embodiment, the cell broadcast entity 11 is also used for: when it is determined that the disaster level corresponding to the disaster alarm data is a non-alarm level, if it is detected that the disaster alarm data has not passed the review operation, the disaster alarm data will not be sent to the cell broadcast center 12.

[0085] If it is detected that the disaster alarm data has not passed the audit, it proves that the disaster alarm data has not passed the audit and there is an abnormality in the disaster alarm data (such as incompleteness or false alarm), then the disaster alarm data will not be sent to the cell broadcast center 12.

[0086] Optionally, when it is determined that the disaster level corresponding to the disaster alarm data is a non-alarm level, if no audit pass operation or audit failure operation is detected within the first preset time after the start time of receiving the disaster alarm data, a prompt is given to conduct an audit within a second preset time. The prompt method may be to display a prompt message on a display screen, to prompt through a speaker, to prompt with a flashing light, etc., which is not limited in this embodiment. By setting the first preset time, the second preset time and the prompt method, the processing speed of the disaster alarm data can be accelerated, and the disaster alarm data that affects driving safety can be sent to the car terminal 15 in a timely manner, so as to avoid similar major traffic accidents to the greatest extent and improve driving safety.

[0087] Further, if no audit passing operation or audit failing operation is detected within the second preset time period, the disaster alarm data is first stored locally, or the disaster alarm data can be sent to the cell broadcast center 12.

[0088] In an exemplary embodiment, the cell broadcast entity 11 is further used to: obtain a first relationship between an alarm data range and a disaster level; and obtain a second relationship between a disaster level and a data transmission rule. Accordingly, the cell broadcast entity 11 is used to determine the disaster level corresponding to the disaster alarm data, specifically to: determine the alarm data range to which the disaster alarm data belongs; and determine the disaster level corresponding to the disaster alarm data according to the alarm data range to which the disaster alarm data belongs and the first relationship.

[0089] The data sending rules at least include sending disaster alarm data in real time and sending disaster alarm data after detecting that the audit is passed.

[0090] Among them, the alarm data range, the first relationship and the second relationship can all be set according to the needs of the actual driving scene. By setting the alarm data range, the first relationship and the second relationship, different driving scenes and alarm requirements can be adapted. For example, in a high-speed driving scene, more attention is paid to road conditions, then the alarm data range for disaster alarm data sent by road sensors is larger, and the disaster level corresponding to the larger alarm data range is the alarm level, and the data sending rule corresponding to the alarm level is to send disaster alarm data in real time, so that the disaster alarm data sent by the road sensor is easier to be sent to the cell broadcast center 12 in real time, so that the driver can get the road danger condition in time.

[0091] The disaster alarm data processing system provided in this embodiment can set the alarm data range corresponding to each disaster sensor, the first relationship between the alarm data range and the disaster level, and the second relationship between the disaster level and the data sending rule according to the needs of the actual driving scene, so that the degree of disaster alarm and the frequency of disaster alarm meet the needs of the actual driving scene.

[0092] In an exemplary embodiment, before the base station 14 is used to send the encoded disaster alarm data to the automobile terminal 15, the base station 14 is also used to: send a channel number setting request to the automobile terminal 15, the channel number setting request is used to request to set a channel number for receiving disaster alarm data; receive the channel number setting result fed back by the automobile terminal 15, the channel number setting result includes the channel number information when the setting is successful or the prompt information when the setting fails. Accordingly, the base station 14 is used to send the encoded disaster alarm data to the automobile terminal 15, specifically to: send the encoded disaster alarm data to the automobile terminal 15 based on the information of the set channel number.

[0093] In order to avoid the car terminal 15 failing to receive the disaster alarm data and further improve driving safety, a request can be made to the car terminal 15 to set a dedicated channel number before sending the data to receive the disaster alarm data. When the car terminal 15 is successfully set up, the set channel number information is fed back, and the base station 14 can send the encoded disaster alarm data to the car terminal 15 based on the channel number information fed back by the car. When the car terminal 15 fails to set up, a prompt message when the setting fails is fed back, and the base station 14 determines that the encoded disaster alarm data cannot be sent to the car. At this time, the base station 14 can request the car terminal 15 to set a dedicated channel number again until the channel number information fed back by the car terminal 15 is obtained. Optionally, if the base station 14 still fails to obtain the channel number information after multiple requests, the car terminal 15 can be marked as an abnormal car terminal 15.

[0094] Optionally, when setting a dedicated channel number, the car terminal 15 can select a broadcast channel number from the available channel range reserved for mobile communication operators according to the 3GPP (full name Third Generation Partnership Project) protocol, and the mobile communication cell broadcast system uses this broadcast channel number as a dedicated channel for broadcasting disaster information.

[0095] In an exemplary embodiment, the encoded disaster alarm data carries the location information of the disaster sensor. The base station 14 control center 13 is used to send the processed disaster alarm data to the base station 14 corresponding to the disaster area, specifically to: obtain the location information of the disaster sensor carried by the encoded disaster alarm data; determine the disaster area and the base station 14 corresponding to the disaster area according to the location information; determine the cell broadcast channel based on the base station 14 control center 13, and send the processed disaster alarm data to the base station 14 corresponding to the disaster area based on the cell broadcast channel.

[0096] The location information of the disaster sensor can be used to determine the location where the disaster occurred. After the disaster location is determined, the disaster area can be obtained by taking the disaster location as the center and expanding the preset range. That is to say, the disaster area includes the disaster location and the surrounding area of ​​the disaster location. The base station 14 control center 13 sends the processed disaster alarm data to the base station 14 corresponding to the disaster area based on the cell broadcast channel, and the base station 14 corresponding to the disaster area broadcasts the disaster alarm data through the wireless channel. Before broadcasting the disaster alarm data through the wireless channel, the base station 14 control center 13 determines the cell broadcast channel. When determining the cell broadcast channel, the base station 14 control center 13 needs to consider multiple factors to ensure the effective transmission and reception of the broadcast information. Multiple factors include, for example: the type of information to be broadcast, the content of the information to be broadcast, the coverage of the information to be broadcast, and the reception quality of the information to be broadcast.

[0097] In an exemplary embodiment, the base station 14 control center 13 is further used to: send the encoded disaster warning data to the base station 14 in the non-disaster area. The base station 14 control center 13 can not only accurately release the disaster warning data to the base station 14 in the disaster area, but also broadcast the disaster warning data in the entire area at the same time, so that the non-disaster area can also be informed of the disaster situation.

[0098] In an exemplary embodiment, the disaster warning data processing system further includes a control device 152 and a mobile communication chip 151 of the automobile terminal 15. The mobile communication chip 151 is used to receive the encoded disaster warning data. The control device 152 is used to control the display device of the automobile to display disaster prompt information based on the encoded disaster warning data, and to control the automobile to reduce its running speed.

[0099] The control device 152 of the automobile includes a communication subsystem, an underlying system, a driving control subsystem, and an audio and video subsystem. Specifically, the mobile communication chip 151 of the communication subsystem of the automobile terminal 15 receives the cell broadcast message, that is, receives the encoded disaster alarm data. The underlying system of the automobile terminal 15 parses the encoded disaster alarm data, obtains the latest disaster alarm data, and generates vehicle control and reminder strategies. The driving control subsystem of the automobile terminal 15 takes actions such as slowing down and stopping the vehicle according to the vehicle control strategy. The audio and video subsystem of the automobile terminal 15 uses sound prompts, screen display prompts, and flashing lights according to the reminder strategy to remind the driver that there are disaster events around, which may affect driving safety.

[0100] See also Figure 2 An embodiment of the present application provides a method for processing disaster alarm data, which is applied to a system for processing disaster alarm data provided by any of the above embodiments.

[0101] The method for processing the disaster warning data includes:

[0102] Step 201: based on the cell broadcast entity, obtain the disaster alarm data transmitted by the disaster sensor, and send the disaster alarm data to the cell broadcast center.

[0103] The cell broadcast entity is used to obtain disaster alarm data transmitted by the disaster sensor and send the disaster alarm data to the cell broadcast center.

[0104] The disaster sensor includes at least one of a geological disaster sensor, a bridge sensor, a tunnel sensor or a road sensor; the disaster alarm data is sent when the disaster sensor determines that the collected data meets the alarm condition.

[0105] Among them, geological disaster sensors are devices used to monitor and warn of geological disasters. They can collect geological environment data in real time and predict and warn possible geological disasters by analyzing these data. Geological disaster sensors can include one or more of the following: earthquake sensors, landslide sensors, debris flow sensors, water level sensors, and rainfall sensors.

[0106] Among them, bridge sensors are used for monitoring the health of bridge structures. Bridge sensors can include one or more of the following: stress and strain sensors, displacement sensors, vibration sensors, environmental sensors, etc.

[0107] Among them, the tunnel sensor is used to monitor the internal environment and structural status of the tunnel. The tunnel sensor may include one or more of the following types: visibility sensor, temperature sensor, oxygen sensor, smoke sensor, tilt sensor, strain sensor, water level sensor, etc.

[0108] Among them, the road sensors related to driving safety are mainly road condition sensors, which can monitor the status of the road surface in real time, such as the degree of wetness, icing conditions, water depth, etc.

[0109] Based on the above tests and experience summarization of the impact of various disaster sensors on driving safety, the sensor monitoring and early warning system can set alarm conditions for each disaster sensor. If the data collected by the disaster sensor reaches the alarm condition, the disaster sensor sends the disaster alarm data to the cell broadcast entity. The alarm condition can be to alarm after reaching the alarm threshold. If the data collected by the disaster sensor reaches the alarm threshold, the disaster sensor sends the disaster alarm data to the cell broadcast entity.

[0110] The disaster alarm data includes data collected by disaster sensors and may also include a disaster alarm prompt field.

[0111] The cell broadcast entity provides access services, collects disaster alarm data that needs to be broadcast, and then transmits the disaster alarm data to the cell broadcast center.

[0112] Step 202: After the disaster warning data is parsed and encoded based on the cell broadcast center, the encoded disaster warning data is sent to the base station control center of the mobile communication network.

[0113] The cell broadcast center connects with the mobile communication network and sends disaster alarm data to the mobile communication network. Optionally, the cell broadcast center connects with the mobile communication network according to the 3GPP (Third Generation Partnership Project) cell broadcast protocol. The cell broadcast center encodes the disaster alarm data from the cell broadcast entity according to the 3GPP cell broadcast protocol. The cell broadcast center is used to parse and encode the disaster alarm data and send the encoded disaster alarm data to the base station control center of the mobile communication network.

[0114] Optionally, the cell broadcast system (including the cell broadcast entity and the cell broadcast center) adopts CMAS (full name Commercial Mobile Alert System) technology that complies with the 3GPP23.041 international specification.

[0115] Step 203: Based on the base station control center, the processed disaster alarm data is sent to the base station corresponding to the disaster area.

[0116] The base station control center is used to perform necessary processing on the disaster alarm data, such as format conversion, encryption, decryption, compression, decompression, etc., to ensure that the disaster alarm data can be correctly transmitted in the mobile communication network. Specifically, the base station control center is used to select the best routing path according to the destination of the disaster alarm data and the topological structure of the mobile communication network. The base station control center is also used to determine the location and identification of the target base station so as to send the disaster alarm data to the correct base station. In this embodiment, the base station control center is used to send the disaster alarm data to the base station corresponding to the disaster area. The base station control center is also used to send the processed disaster alarm data to the target base station through the data channel of the mobile communication network. During the transmission of the disaster alarm data, the base station control center will monitor the transmission status of the disaster alarm data to ensure the integrity and reliability of the disaster alarm data.

[0117] Step 204, based on the base station corresponding to the disaster area, the encoded disaster warning data is sent to the automobile terminal.

[0118] The communication system of the car terminal is equipped with a mobile communication chip, which supports public mobile communication network communication. The public mobile communication network includes 3G (full name 3rd Generation Mobile Communication Technology), 4G (full name 4th Generation Mobile Communication Technology) and 5G (full name 5th Generation Mobile Communication Technology). The base station sends the encoded disaster alarm data to the mobile communication chip. After receiving the disaster alarm data, the car terminal can promptly remind the driver that a disaster has occurred, thereby helping the driver avoid the disaster area and improving driving safety.

[0119] The method provided in this embodiment can quickly send disaster alarm data related to driving safety to car terminals around the disaster site through the mobile communication network cell broadcast system, and support the car terminals to automatically control the vehicle according to the disaster alarm data to avoid accidents. Compared with the traditional solution, the disaster alarm data processing system provided in this embodiment can send disaster alarm data that affects driving safety to the car terminal in a timely manner, so as to avoid similar major traffic accidents to the greatest extent and improve driving safety.

[0120] For an exemplary embodiment, see Figure 3 Step 201 sends the disaster warning data to the cell broadcast center, including:

[0121] Step 301: When it is determined that the disaster level corresponding to the disaster alarm data is the alarm level, the disaster alarm data is sent to the cell broadcast center in real time.

[0122] Step 302: When it is determined that the disaster level corresponding to the disaster alarm data is a non-alarm level, if it is detected that the audit pass operation of the disaster alarm data is detected, the disaster alarm data is sent to the cell broadcast center.

[0123] Audit rules can be set in the cell broadcast entity so that disaster alarm data of alarm level (which can also be understood as a higher level) can be sent to the cell broadcast center without manual review, while disaster alarm data of non-alarm level (which can also be understood as a lower level) can be sent to the cell broadcast center after manual review or not sent. Correspondingly, when it is determined that the disaster level corresponding to the disaster alarm data is the alarm level, the disaster alarm data is sent in real time (immediately) to the cell broadcast center. When it is determined that the disaster level corresponding to the disaster alarm data is the non-alarm level, if the audit pass operation of the disaster alarm data is detected, the disaster alarm data is sent to the cell broadcast center.

[0124] Among them, the audit pass operation is generated after the staff verifies the disaster alarm data and confirms that the disaster alarm data is correct. The audit pass operation can also include the operation of the staff to modify the disaster alarm data. Correspondingly, after the disaster alarm data is modified according to the operation of modifying the disaster alarm data, the modified disaster alarm data is sent to the community broadcast center. The accuracy of the disaster alarm data can be improved by the staff reviewing and modifying the disaster alarm data.

[0125] Among them, the alarm level can be understood as the level corresponding to when the disaster alarm data is greater than or equal to the early warning disaster alarm data, and the non-alarm level can be understood as the level corresponding to when the disaster alarm data is less than the early warning disaster alarm data. The non-alarm level can also be divided into multiple sub-levels, and different sub-levels correspond to different manual review rules. For example, the manual review rules corresponding to higher levels are simpler, such as only one manual review is required to pass the review. For example, the manual review rules corresponding to lower levels are more complex, such as multiple audits and confirmations are required before the review can be passed.

[0126] Optionally, different disaster sensors correspond to different early warning disaster alarm data, for example, bridge sensors correspond to the first early warning disaster data, geological disaster sensors correspond to the second early warning disaster data, tunnel sensors correspond to the third early warning disaster data, and road sensors correspond to the fourth early warning disaster data. Optionally, different early warning disaster alarm data can be set for different driving scenarios. For example, if the driving scenario is mostly on bridges, the first early warning disaster alarm data corresponding to the bridge sensor is lower to enhance the monitoring of bridges.

[0127] Optionally, the data collected by multiple different disaster sensors can be calculated as one data, and then the one data can be compared with the early warning disaster data. In the case where the one data is greater than or equal to the early warning disaster data, the one data can be sent to the cell broadcast center without manual review. In the case where the one data is less than the early warning disaster data, if the review of the disaster alarm data is detected, the disaster alarm data will be sent to the cell broadcast center.

[0128] Step 303: when it is determined that the disaster level corresponding to the disaster alarm data is a non-alarm level, if it is detected that the disaster alarm data has not passed the review operation, the disaster alarm data will not be sent to the cell broadcast center.

[0129] If it is detected that the disaster alarm data has not passed the review operation, it proves that the disaster alarm data has not passed the review and there are abnormalities in the disaster alarm data (such as incompleteness or false alarm), then the disaster alarm data will not be sent to the cell broadcast center.

[0130] Optionally, when it is determined that the disaster level corresponding to the disaster alarm data is a non-alarm level, if no audit pass operation or audit fail operation is detected within the first preset time after the start time of receiving the disaster alarm data, a prompt is given to conduct an audit within a second preset time. The prompt method may be displaying a prompt message on a display screen, prompting through a speaker, flashing a light, etc., which is not limited in this embodiment. By setting the first preset time, the second preset time and the prompt method, the processing speed of the disaster alarm data can be accelerated, and the disaster alarm data that affects driving safety can be sent to the car terminal in a timely manner to avoid similar major traffic accidents to the greatest extent and improve driving safety.

[0131] Further, if no audit passing operation or audit failing operation is detected within the second preset time period, the disaster alarm data is first stored locally, or the disaster alarm data can be sent to the cell broadcast center.

[0132] The method provided in this embodiment can quickly send disaster alarm data related to driving safety to automobile terminals around the disaster site through the mobile communication network cell broadcast system when the disaster level corresponding to the disaster alarm data is the alarm level, and support the automobile terminals to automatically control the vehicle according to the disaster alarm data to avoid accidents. Compared with the traditional solution, the disaster alarm data processing system provided in this embodiment can send disaster alarm data that affects driving safety to the automobile terminal in a timely manner, so as to avoid similar major traffic accidents to the greatest extent and improve driving safety.

[0133] In addition, when the disaster level corresponding to the disaster alarm data is a non-alarm level, the disaster alarm data will be sent to the cell broadcast center only after the disaster alarm data has been approved. This is done to improve the accuracy of the disaster alarm data and avoid false alarms.

[0134] In an exemplary embodiment, see Figure 4 , the method for processing disaster alarm data also includes:

[0135] Step 401, before determining that the disaster level corresponding to the disaster alarm data is the alarm level, obtain a first relationship between the alarm data range and the disaster level.

[0136] Step 402, obtaining a second relationship between the disaster level and the data sending rule; wherein the data sending rule at least includes sending the disaster alarm data in real time, and sending the disaster alarm data after detecting that the audit is passed.

[0137] Accordingly, when determining the disaster level corresponding to the disaster alarm data, it includes: step one, determining the alarm data range to which the disaster alarm data belongs; step two, determining the disaster level corresponding to the disaster alarm data based on the alarm data range and the first relationship.

[0138] The data sending rules at least include sending disaster alarm data in real time and sending disaster alarm data after detecting that the audit is passed.

[0139] Among them, the alarm data range, the first relationship and the second relationship can all be set according to the needs of the actual driving scene. By setting the alarm data range, the first relationship and the second relationship, different driving scenes and alarm requirements can be adapted. For example, in a high-speed driving scenario, more attention is paid to road conditions, so the alarm data range for disaster alarm data sent by road sensors is larger, and the disaster level corresponding to the larger alarm data range is the alarm level, and the data sending rule corresponding to the alarm level is to send disaster alarm data in real time. In this way, the disaster alarm data sent by the road sensor is easier to be sent to the community broadcast center in real time, so that the driver can be informed of the dangerous road conditions in time.

[0140] The method provided in this embodiment can set the alarm data range corresponding to each disaster sensor, the first relationship between the alarm data range and the disaster level, and the second relationship between the disaster level and the data sending rule according to the needs of the actual driving scene, so that the degree of disaster alarm and the frequency of disaster alarm meet the needs of the actual driving scene.

[0141] For an exemplary embodiment, see Figure 5 , before step 204, the method further includes:

[0142] Step 501, sending a channel number setting request to a car terminal, where the channel number setting request is used to request setting a channel number for receiving disaster alarm data.

[0143] Step 502, receiving the channel number setting result fed back by the car, the channel number setting result including the channel number information when the setting is successful or the prompt information when the setting fails.

[0144] Accordingly, step 204 sends the encoded disaster warning data to the vehicle terminal, including: sending the encoded disaster warning data to the vehicle terminal based on the set channel number information.

[0145] In order to avoid the car terminal failing to receive disaster alarm data and to further improve driving safety, a dedicated channel number can be requested to be set to receive disaster alarm data from the car terminal before sending. When the car terminal is successfully set up, the set channel number information is fed back, and the base station can send the encoded disaster alarm data to the car terminal based on the channel number information fed back by the car. When the car terminal fails to set up, a prompt message is fed back when the setting fails. The base station determines that the encoded disaster alarm data cannot be sent to the car. At this time, the base station can request the car terminal to set a dedicated channel number again until the channel number information fed back by the car terminal is obtained. Optionally, if the base station still fails to obtain the channel number information after multiple requests, the car terminal can be marked as an abnormal car terminal.

[0146] Optionally, when setting a dedicated channel number, the automobile terminal can select a broadcast channel number within the available channel range reserved for mobile communication operators according to the 3GPP (full name Third Generation Partnership Project) protocol. The mobile communication cell broadcast system uses this broadcast channel number as a dedicated channel for broadcasting disaster information.

[0147] In an exemplary embodiment, the encoded disaster warning data carries the location information of the disaster sensor. Figure 6 , step 203 comprises:

[0148] Step 601: Based on the base station control center, the location information of the disaster sensor carried by the encoded disaster alarm data is obtained.

[0149] Step 602: Determine the disaster area and the base station corresponding to the disaster area according to the location information.

[0150] Step 603: determine the cell broadcast channel based on the base station control center, and send the encoded disaster warning data to the base station corresponding to the disaster area based on the cell broadcast channel.

[0151] The location information of the disaster sensor can be used to determine the location where the disaster occurred. After the disaster location is determined, the disaster area can be obtained by taking the disaster location as the center and expanding the preset range. That is to say, the disaster area includes the disaster location and the surrounding area of ​​the disaster location. Based on the cell broadcast channel, the base station control center sends the processed disaster alarm data to the base station corresponding to the disaster area, and the base station corresponding to the disaster area broadcasts the disaster alarm data through the wireless channel. Before broadcasting the disaster alarm data through the wireless channel, the base station control center determines the cell broadcast channel. When determining the cell broadcast channel, the base station control center needs to consider multiple factors to ensure the effective transmission and reception of the broadcast information. Multiple factors include, for example: the type of information to be broadcast, the content of the information to be broadcast, the coverage of the information to be broadcast, and the reception quality of the information to be broadcast.

[0152] In an exemplary embodiment, the method for processing disaster alarm data further includes: step 1, based on the base station control center, sending the encoded disaster alarm data to the base station in the non-disaster area. The base station control center can accurately release the disaster alarm data to the base station in the disaster area, and can also broadcast the disaster alarm data simultaneously in the entire area, so that the non-disaster area can also be informed of the disaster situation.

[0153] In an exemplary embodiment, the method for processing disaster alarm data also includes: step one, receiving the encoded disaster alarm data based on the mobile communication chip of the automobile terminal; using the control device of the automobile terminal to control the display device of the automobile to display disaster warning information according to the encoded disaster alarm data, and controlling the automobile to reduce its running speed.

[0154] The control device of the car includes a communication subsystem, an underlying system, a driving control subsystem, and an audio and video subsystem. Specifically, the mobile communication chip of the car terminal communication subsystem receives the cell broadcast message, that is, receives the encoded disaster alarm data. The car terminal underlying system parses the encoded disaster alarm data, obtains the latest disaster alarm data, and generates vehicle control and reminder strategies. The car terminal driving control subsystem takes actions such as slowing down and stopping the vehicle according to the vehicle control strategy. The car terminal audio and video subsystem uses sound prompts, screen display prompts, and flashing lights according to the reminder strategy to remind the driver that there are disaster events around, which may affect driving safety.
