Detailed Description

The air defense and disaster prevention alarm equipment is an important component of urban air defense and disaster prevention engineering, the existing air defense and disaster prevention alarm equipment covers the city by sound through sound amplification equipment, and the notification effect of the air defense and disaster prevention alarm is poor when air attack or disaster occurs because the information which can be transmitted by sound is simple and single.

In view of this, the core of the broadcast method for the air defense and disaster prevention alarm provided in the embodiment of the present application lies in the following aspects:

1. because the Android and iOS two major operating systems popular in the mobile terminal on the market at present control the system level authority strictly, and the common Bluetooth transmission needs to be paired and connected, the pairing process cannot meet the timeliness requirement of the air defense and disaster prevention alarm. Therefore, the Bluetooth name data and/or the Bluetooth broadcast data are used for sending the air defense and disaster prevention alarm.

2. If the data transmission universality is higher by adopting the Bluetooth technology, but the safety is lower, and the requirement on the communication safety is extremely high due to the particularity of the civil air defense application field, therefore, the encryption and the content verification are required, and the potential safety hazard is prevented in the bud.

3. In order to completely acquire the bluetooth data, the bluetooth data needs to be continuously polled, so that duplicate removal verification needs to be performed, and the purpose of accurately receiving the bluetooth data is achieved.

4. The received broadcast content comprises air defense and disaster prevention alarms, intelligent voice texts, regional/rendezvous point evacuation personnel information and peripheral engineering masking personnel information, and after the broadcast content is received, subsequent business operations such as evacuation guidance, masking navigation and the like need to be executed, so that the whole system forms a closed loop.

As shown in fig. 1, the embodiment of the present application is applied to a mobile device 102 with a bluetooth module, such as a mobile phone, a tablet computer, a palmtop computer, a television, a home alarm terminal, a car multimedia screen, and the like. The embodiment of the application receives the bluetooth signal sent by the bluetooth module 101, and the bluetooth signal is used as a broadcasting means, so that the air defense and disaster prevention alarm can be sent to any mobile device 102 with the bluetooth module, a digital broadcasting means of the air defense and disaster prevention alarm is provided, and the air defense and disaster prevention alarm can be broadcasted more conveniently by receiving the disaster prevention information data carried in the bluetooth signal, thereby greatly improving the notification effect of the air defense and disaster prevention alarm.

To make the objects, technical solutions and advantages of the present application more clear, the present application will be further described in detail with reference to the accompanying drawings and specific embodiments.

Example one

Fig. 2 is a schematic flow chart of a broadcasting method of an air defense and disaster prevention alarm provided in an embodiment of the present application, and as shown in fig. 2, the embodiment mainly includes:

s201: searching a Bluetooth signal, and receiving Bluetooth data when the Bluetooth signal is acquired; the Bluetooth data is disaster prevention information data carried by the Bluetooth signal; the bluetooth data includes: at least one of bluetooth name data or bluetooth broadcast data; the Bluetooth signal is a Bluetooth signal sent by unidirectional broadcasting.

In disaster and wartime, the civil network is unreliable, and broadcasting of air defense and disaster prevention alarms and evacuation or masking of personnel need to be performed in time in a civil air defense multimode communication private network mode, so that the Bluetooth signal in the embodiment of the application is a Bluetooth signal sent by unidirectional broadcasting. The method provided by the first embodiment of the present application needs to be premised on that the mobile terminal turns on the bluetooth module of the local device, and the bluetooth module can normally receive and transmit data. The mobile terminal continuously searches for the Bluetooth signal, and receives Bluetooth data carried in the Bluetooth signal when the Bluetooth signal is obtained.

Because the bluetooth data transmission needs to be paired and connected, the timeliness requirement of the air defense and disaster prevention alarm cannot be met in the pairing process, and after the connection is established by general bluetooth equipment, the two-way communication can be realized, so that the safety of the air defense and disaster prevention alarm system can be endangered. To solve this problem, the following three possible embodiments can be adopted:

a: in a possible implementation mode, the bluetooth module is set to a broadcast working mode, and the broadcast data is used to broadcast the air defense and disaster prevention alarm, so that the content of the bluetooth broadcast data is received as long as the bluetooth module enters the coverage range of the bluetooth signal. Because the broadcast working mode of the Bluetooth module is one-way communication, the safety of the air defense and disaster prevention alarm system can be guaranteed.

B: in another possible embodiment, the transmission of bluetooth data is performed by modifying the bluetooth name. As long as the Bluetooth signal enters the coverage range of the Bluetooth signal, the instruction for modifying the Bluetooth name can be received, the Bluetooth data carried by the Bluetooth name data can also be received, and the process of searching the Bluetooth name data is also unidirectional, so that the safety of the air defense and disaster prevention alarm system can be guaranteed.

C: in another possible embodiment, a bluetooth module with a broadcast mode of operation is used. The method not only sends disaster prevention information data through the Bluetooth name data in a mode of modifying the Bluetooth name, but also broadcasts the air defense and disaster prevention alarm by using the Bluetooth broadcast data.

S202: after one round of Bluetooth signal reception is finished, verifying whether the received Bluetooth data is complete; and if the Bluetooth data is not complete, returning to the step of searching the Bluetooth signal, and receiving the missing part in the Bluetooth data.

And under the condition that the Bluetooth data is the Bluetooth name data, checking whether the Bluetooth name data is complete or not according to the byte quantity information carried by the Bluetooth name data. Because the Bluetooth name data is short, the safety verification can be directly carried out on the Bluetooth name data, and whether the Bluetooth name data is complete or not is verified through the safety verification.

In the case that the bluetooth data is the bluetooth broadcast data, after the bluetooth broadcast data is received, it is first required to verify whether the received bluetooth broadcast data is complete, specifically, the following steps 1 to 5 may be adopted to perform integrity verification on the received bluetooth broadcast data:

step 1, dividing the received Bluetooth broadcast data into at least one data frame according to a frame ending identifier carried in each data frame; and each data frame at most comprises a preset number of bytes.

And 2, aiming at each data frame, checking whether the frame is complete or not according to the byte quantity information carried by the data frame.

And 3, when the frame is complete, extracting the frame number of the frame, and judging whether the frame is the first data frame or not according to the frame number of the frame.

Step 4, if the frame is the first data frame, extracting the total frame number of the Bluetooth broadcast data; and judging whether the Bluetooth broadcast data is single-frame data or multi-frame data according to the total frame number.

Here, if the frame is the first data frame and the bluetooth broadcast data is single frame data, the single frame data of the frame must be complete since the single frame integrity of the first data frame has been verified. The step of verifying the bluetooth broadcast data may be directly performed.

Step 5, if the frame is not the first data frame, judging whether the first data frame exists in the Bluetooth broadcast data; and if the first data frame exists, judging whether the Bluetooth broadcast data is complete or not according to the frame number of each data frame and the total frame number.

If the Bluetooth broadcast data of the multi-frame is not complete, recording the frame number and the total frame number of the data frame with complete data, obtaining the frame number of the data frame with incomplete data according to the frame number and the total frame number of the data frame with complete data, and then returning to the step of searching the Bluetooth signal. And when the Bluetooth signal is acquired, receiving the incomplete data frame according to the frame number of the data frame with incomplete data until all the data frames in the Bluetooth broadcast data of the plurality of frames are received. If the first data frame does not exist in the Bluetooth broadcast data, the Bluetooth broadcast data is not complete, the frame number of the data frame with complete data is recorded, and the step of searching the Bluetooth signal is returned. And when the Bluetooth signal is acquired, receiving the incomplete data frame according to the frame number of the data frame with complete data until all the data frames in the multi-frame Bluetooth broadcast data are received.

S203: and if the Bluetooth data is complete, performing security verification on the Bluetooth data, and executing the instruction in the Bluetooth data passing the security verification.

Here, the security verifying the bluetooth data may include: at least one of a key check, a content check, and a repeatability check.

Through the multiple verification, the obtained Bluetooth data is complete and legal Bluetooth data, and the Bluetooth data can be executed.

For the method provided by the first embodiment of the application, the most important function is to provide a broadcast function of the air defense and disaster prevention alarm. Because the communication packet size of the bluetooth signal is limited, and the air defense and disaster prevention alarm needs to be quickly notified in place in disaster or wartime, voice information with large data volume cannot be directly transmitted to the mobile terminal. Specifically, need follow acquire the voice broadcast text in the bluetooth data, use the voice broadcast text carries out voice broadcast. Further, the voice broadcast Text may be converted into voice information using a Text To Speech (TTS); and playing the converted voice information. Thereby achieving the purposes of quick transmission and timely broadcast.

In a possible implementation manner, the broadcast of the air defense and disaster prevention alarm needs to record a play log on the mobile terminal and report to the server when the civil network is available and can be connected to the server through the civil network, so that the broadcast is used as a decision basis for commanding and scheduling of the civil air defense command center.

As the civil network is unreliable in disaster or wartime, people need to be instructed to evacuate or shelter through bluetooth signals.

When people are instructed to evacuate through the Bluetooth signals, evacuation instructions need to be sent through the Bluetooth signals, and then evacuation modes selected by users are obtained; and extracting the evacuation site corresponding to the evacuation mode from the Bluetooth data according to the evacuation mode. Specifically, when the evacuation manner is self-propelled forward, the evacuation location corresponding to the evacuation manner is the address of the evacuation location; and when the evacuation mode is unified forward, the evacuation site corresponding to the evacuation mode is the address of the evacuation rendezvous site.

Because the civil network is unreliable in disaster or wartime, when evacuation guidance is carried out, a local navigation function needs to be provided, a navigation path can be calculated locally, and navigation is started by taking an evacuation place as a destination. Here, the nearest evacuation site may be used as the destination, or an evacuation site selected by the user may be used as the destination. In addition, whether the civil network can be connected or not can be verified at the moment, and if the civil network can be connected, the user can select a third-party navigation tool to navigate.

In addition, in disaster or wartime, due to the disconnection of the civil network, the mobile terminal cannot acquire the evacuation personnel information in the evacuation site temporarily, and needs to push the information through a bluetooth signal as the basis for evacuation guidance. Specifically, it may be determined whether first evacuation personnel information corresponding to the evacuation location exists in the bluetooth data; wherein the first evacuation people information comprises the number of people existing at the evacuation location; and if so, storing the first evacuated personnel information and reminding a user to check. Therefore, the number of people in each evacuation place can be reminded, evacuation guidance is carried out according to the number of people in each evacuation place, and the situation that the users go to the evacuation places with the full number of people is avoided.

Further, when the evacuation guidance service function is executed, whether the evacuation guidance service function can pass through a civil network or not can be judged, and if the evacuation guidance service function can be connected to the server, second evacuation personnel information corresponding to the evacuation site is reported to the server; the second evacuation personnel information is information that a user is going to the evacuation site.

The manner of conducting the shelter guidance is similar to the manner of conducting the evacuation guidance. Specifically, if the instruction in the bluetooth data is a masking instruction, extracting a masking place from the bluetooth data; and starting navigation by taking the masking place as a destination. Likewise, the nearest masking place may be automatically selected by the masking place, or a masking place selected by the user may be used. And, in case of being able to connect to the residential network, the user may be allowed to select a navigation tool of a third party for navigation. And the information of the masking personnel at the masking place is pushed through the Bluetooth signal as the basis of the masking guide. Specifically, whether first masking personnel information corresponding to the masking place exists in the bluetooth data or not can be judged; wherein the first masking person information includes the number of existing persons of the masking place; and if so, storing the first masking personnel information and reminding a user to view. Therefore, the number of people in each shelter site can be reminded, and the shelter guidance is carried out according to the number of people in each shelter site, so that the user is prevented from going to the shelter site with the full number of people. Further, when the masking guidance service function is executed, whether the second masking personnel can pass through the civil network or not can be judged, and if the second masking personnel can be connected to the server, second masking personnel information corresponding to the masking place is reported to the server; the second masking personnel information is information that the user is going to the masking place.

At present, the air defense and disaster prevention alarm system only covers the city with sound through the public address equipment, so that the civil defense department cannot master the sounding test effect when the civil defense alarm sounds in a test every year. Therefore, the air defense and disaster prevention alarm broadcasting system provided by the embodiment of the application can provide an alarm sounding function, specifically, when the instruction is an alarm sounding instruction, an evaluation questionnaire program is started, and an evaluation result formed by a user according to the evaluation questionnaire program is obtained; and uploading the evaluation result to a server. Therefore, the basis can be provided for the overall planning and construction of the alarm, and the alarm sounds to the public to make a counter sound to form a closed loop.

In addition, when people's air defense knowledge propaganda is carried out at ordinary times, and necessary people's air defense knowledge propaganda and guidance are carried out in disaster or wartime, people's air defense knowledge recommendation instructions can be carried through Bluetooth data, and people's air defense knowledge catalogues which recommend users to read and know are carried in the Bluetooth data to guide the users to read and learn the people's air defense knowledge stored in the mobile equipment. Moreover, the browsing records of the user can be reported to the server through the civil network, so that the civil air defense office can master the effect of civil air defense propaganda and education in real time.

Example two

As shown in fig. 3, in a broadcast method of an air defense and disaster prevention alarm provided in the second embodiment of the present application, in a case that the bluetooth data is bluetooth name data, the steps of receiving the bluetooth data and verifying security include:

s301: a search for bluetooth signals is constantly made.

In order to solve the problems of timeliness communication and safety, the Bluetooth data is sent in a mode of modifying the Bluetooth name. As long as the Bluetooth signal coverage range is entered, the instruction for modifying the Bluetooth name can be received, and the disaster prevention information data carried by the Bluetooth name data can be received.

S302: when the Bluetooth signal is acquired, whether Bluetooth name data exists in the Bluetooth signal is judged.

S303: and receiving the Bluetooth name data until the communication idle time reaches a preset time threshold.

When using bluetooth name data as bluetooth data, carrying out disaster prevention information data's transmission through the mode of revising the bluetooth name, constantly search for the bluetooth name data that the bluetooth signal carried, specifically include:

judging whether the acquired Bluetooth name data is the same as the existing Bluetooth name or not, and if the acquired Bluetooth name data is not the same as the existing Bluetooth name, taking the acquired Bluetooth name data as Bluetooth data.

When the bluetooth name data is used as the bluetooth data and the disaster prevention information data is transmitted by modifying the bluetooth name, the bluetooth name data is received byte by byte, the length of the bluetooth name is usually 16 bytes, and the disaster prevention information data with less than 16 bytes can be transmitted through the bluetooth name data. Timing communication idle time after receiving one byte of Bluetooth name data; in general, after receiving one byte of bluetooth name data, the communication idle time is counted from 0. In addition, the unit of time measurement may be millisecond ms. And when the communication idle time exceeds a preset time threshold, for example, 100ms, stopping receiving the bluetooth name data, and entering the step of verifying whether the received bluetooth name data is complete.

S304: and verifying whether the Bluetooth name data is complete.

Whether the Bluetooth name data is complete or not can be checked according to the byte number information carried by the Bluetooth name data. Because the Bluetooth name data is short, the safety verification can be directly carried out on the Bluetooth name data, and whether the Bluetooth name data is complete or not is verified through the safety verification.

S305: and after the Bluetooth name data is received completely, carrying out key verification and judging the safety of the Bluetooth name data.

Preferably, the bluetooth name data may be encrypted by using an asymmetric encryption technology, and after the bluetooth name data is obtained, the key verification may be performed on the bluetooth name data according to a preset key.

S306: and if the Bluetooth name data passes the key verification and is determined to be legal Bluetooth name data, performing content verification according to the first content verification code and the second content verification code.

In addition to the key verification, another method for increasing the security of bluetooth signal transmission is to perform content verification on the bluetooth name data, specifically, perform content verification on the bluetooth name data through the following steps 1 to 3:

step 1, extracting a first content check code from the Bluetooth name data;

step 2, calculating according to each byte in the Bluetooth name data to obtain a second content check code;

and 3, if the first content check code is the same as the second content check code, the Bluetooth name data passes the security verification.

S307: and after the content is verified to be legal, performing duplicate removal verification according to the duplicate removal identification code.

In order to prevent repeated broadcast of the air defense and disaster prevention alarm which has been broadcast, the bluetooth name data can be repeatedly verified, and the following steps 1 to 3 can be adopted:

step 1, extracting a duplication-removing identification code from Bluetooth name data;

step 2, after the instruction in the Bluetooth name data which passes the repeatability verification is executed, storing the duplicate removal identification code;

and 3, before executing the instruction in the Bluetooth name data which passes the repeated verification, judging according to the duplicate removal identification code when executing the step of performing the repeated verification on the Bluetooth name data, and if the duplicate removal identification code is not stored, executing the instruction in the Bluetooth name data which passes the repeated verification.

S308: and when the duplication elimination verification is determined that the broadcast content is not executed, executing the instruction in the Bluetooth name data passing the security verification.

EXAMPLE III

As shown in fig. 4, in a broadcast method of an air defense and disaster prevention alarm provided in the third embodiment of the present application, in a case that the bluetooth data is bluetooth name data, the step of receiving and verifying the bluetooth broadcast data includes:

s401: a search for bluetooth signals is constantly made.

The Bluetooth module is set to be in a broadcast working mode, the broadcasting of the air defense and disaster prevention alarm is carried out by using the Bluetooth broadcast data, and the content of the Bluetooth broadcast data is received as long as the Bluetooth broadcast data enters the coverage range of the Bluetooth signal. Because the broadcast working mode of the Bluetooth module is one-way communication, the safety of the air defense and disaster prevention alarm system can be guaranteed.

S402: when the Bluetooth signal is acquired, whether Bluetooth broadcast data exists in the Bluetooth signal is judged.

S403: and receiving the Bluetooth broadcast data until the communication idle time reaches a preset time threshold.

When the Bluetooth broadcast data is used as the Bluetooth data and disaster prevention information data is transmitted through the Bluetooth broadcast data, the Bluetooth broadcast data is received byte by byte, and the communication idle time is timed after each byte of the Bluetooth broadcast data is received; generally, after receiving one byte of bluetooth broadcast data, the communication idle time is counted from 0. In addition, the unit of time measurement may be millisecond ms.

And when the communication idle time exceeds a preset time threshold, stopping receiving the Bluetooth broadcast data, and entering the step of verifying whether the received Bluetooth broadcast data is complete. For example, if the communication idle time reaches 100ms, the bluetooth broadcast data reception is stopped, and the step of verifying whether the received bluetooth broadcast data is complete is performed.

S404: dividing the received Bluetooth broadcast data into at least one data frame according to a frame ending identifier carried in each data frame; and each data frame at most comprises a preset number of bytes, and whether each frame is complete or not is verified.

When the bluetooth broadcast data is used as the bluetooth data and the disaster prevention information data is transmitted through the bluetooth broadcast data, the transmission is usually performed by using a data frame as a unit, and the length of one data frame is different for different bluetooth modules. If the Bluetooth broadcast data is long and the content is more, a plurality of data frames are needed to be used for transmitting the Bluetooth broadcast data.

In the process of receiving the bluetooth broadcast data, the bluetooth broadcast data is received byte by byte, and because the bluetooth signal is used for data communication, in the process of data communication, due to the problem of the strength of the bluetooth signal or the problem of the user in the process of moving, the situations of data loss, damage and the like may exist, and the bluetooth broadcast data is not completely received.

Therefore, in order to ensure that all installed mobile terminals within the coverage of the bluetooth signal can receive complete information, the padding and packaging operations need to be performed during the receiving process.

Firstly, dividing the received bluetooth broadcast data into at least one data frame according to a frame end identifier carried in each data frame. If the Bluetooth broadcast data is single-frame data, the data frame is only one, and the length of the single-frame data of the frame is not fixed and contains a preset number of bytes at most. Different bluetooth module, the number of bytes of predetermined quantity is different. If the Bluetooth broadcast data is multi-frame data, the number of the data frames is at least two, the length of the last frame of data is not fixed, and the last frame of data contains a preset number of bytes at most. The length of the rest frame data is fixed and is a preset number of bytes. Different bluetooth module, the number of bytes of predetermined quantity is different.

And for each data frame, checking whether the frame is complete according to the byte number information carried by the data frame.

S405: acquiring a first data frame of the Bluetooth broadcast data, extracting the total frame number of the Bluetooth broadcast data, and judging whether the Bluetooth broadcast data is single-frame data or multi-frame data; and if the Bluetooth broadcast data is single-frame data, directly entering a checking step to judge the safety of the Bluetooth broadcast data.

S406: if the Bluetooth broadcast data is multi-frame data, polling to receive the multi-frame data, judging whether the Bluetooth broadcast data content of the multi-frame data is completely received when the communication idle time reaches a preset time threshold, if not, performing packet supplementing operation, wherein the packet supplementing operation is a vacant frame which is not received in the polling to receive the multi-frame data, and repeating the operation when the communication idle time reaches the preset time threshold each time until the multi-frame content is completely received.

S407: and after the Bluetooth broadcast data is received completely, carrying out key verification and judging the safety of the Bluetooth broadcast data.

The bluetooth signal may be intercepted in the air and may also be decompiled, thereby causing communication protocol leakage, causing illegal personnel to disturb the normal sending process of air defense and disaster prevention alarms, causing alarm mistaken sounding, disturbing social order, even generating important group safety hidden dangers of transmitting illegal violation information and the like. In summary, the civil air defense application field has extremely high requirements on communication security, and therefore, key verification is required to be adopted to prevent potential safety hazards in the bud. Preferably, the bluetooth broadcast data may be encrypted by using an asymmetric encryption technology, and after the bluetooth broadcast data is acquired, the key may be verified according to a preset key.

S408: and if the Bluetooth broadcast data is determined to be legal after passing the key verification, performing content verification according to the first content verification code and the second content verification code.

Besides the key verification, another method for increasing the security of bluetooth signal transmission is to perform content verification on bluetooth broadcast data, and may be performed by using the following steps 1 to 3:

step 1, extracting a first content check code from a first data frame of the Bluetooth broadcast data; specifically, the first content check code may be calculated by using a checksum.

Step 2, calculating according to each byte in the Bluetooth broadcast data to obtain a second content check code; specifically, the second content check code can be calculated in a checksum mode, and because the calculation modes are the same, if the bluetooth broadcast data is correct, the first check code and the second check code are the same.

And 3, if the first content check code is the same as the second content check code, the Bluetooth broadcast data passes the security verification.

S409: and after the content is verified to be legal, performing duplicate removal verification according to the duplicate removal identification code.

In order to ensure that the mobile device at both a long distance and a short distance can receive the air defense and disaster prevention alarm in the response period of the air defense and disaster prevention alarm, the bluetooth signal is broadcast circularly in the whole corresponding period, and each circulation is divided into two times of bluetooth signal transmission, wherein the bluetooth signal is transmitted once at higher power and then transmitted once at lower power. Also, as shown in fig. 5, if the bluetooth signal covers A, B adjacent two cells, it is possible to span two cells, or even more cells, during the response period when the mobile terminal is in a high speed motion state. In order to prevent repeated broadcast of the air defense and disaster prevention alarm which has been broadcast, the repeatability verification can be performed on the bluetooth broadcast data, and specifically, the following steps 1 to 3 can be adopted:

step 1, extracting a duplicate identification code from Bluetooth broadcast data.

And 2, storing the duplicate removal identification code after executing the instruction in the Bluetooth broadcast data which passes the repeatability verification.

And 3, before executing the instruction in the Bluetooth broadcast data which passes the repeated verification, judging according to the duplication-removing identification code, and if the duplication-removing identification code is not stored, executing the instruction in the Bluetooth broadcast data which passes the repeated verification.

As shown in fig. 5, bluetooth covers A, B two adjacent cells, and when the mobile terminal is in a high-speed driving state, it may be possible to span two cells or even more cells in a response period; when the mobile terminal receives the Bluetooth broadcast data in the Bluetooth information in the cell A and broadcasts the air defense and disaster prevention alarm, the duplicate removal identification code of the broadcasted Bluetooth broadcast data can be recorded, and when the mobile terminal roams to the cell B, the disaster prevention information data carrying the same duplicate removal identification code can not be broadcasted repeatedly; when the mobile terminal receives the Bluetooth broadcast data in the Bluetooth information in the cell A but does not receive the Bluetooth broadcast data completely, and roams to the cell B, the mobile terminal can continue to receive the Bluetooth broadcast data to complement disaster prevention information data content carried in the Bluetooth broadcast data and then broadcast the disaster prevention information data content.

S410: and when the duplication elimination verification is determined that the broadcast content is not executed, executing the instruction in the Bluetooth broadcast data passing the security verification.
