In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the following description will be made with reference to the accompanying drawings by way of specific embodiments.
Fig. 1 is a schematic structural diagram of an air defense and disaster prevention alarm control system according to an embodiment of the present application. As shown in fig. 1, the air defense and disaster prevention alarm control system 10 may include at least one control center 11 and a plurality of terminal controllers 12.
The control center 11 is configured to generate first short message information, and send the first short message information to the beidou master control station. The first short message information is used for indicating the Beidou master control station to bring the terminal controller 12 specified in the first short message information into the first communication packet established by the control center 11.
The control center 11 is further configured to generate an alarm issuing instruction, and send the alarm issuing instruction to the first communication packet through the beidou master station.
The terminal controller 12 in the first communication packet is configured to execute the alert issue instruction after receiving the alert issue instruction.
In the prior art, beidou communication has a Beidou communication card similar to a mobile phone card, and the Beidou communication card is inserted into Beidou communication equipment to jointly complete network access communication. The Beidou communication card has a card number, also called an ID, similar to a mobile phone number. The Beidou communication card is divided into a command card and a common card.
In this embodiment, the Beidou master control station is an operation control center of the Beidou system. The control center 11 configures a director card or a normal card, and the terminal controller 12 configures a normal card. In the application, a control center configured with a command card or a common card can communicate with a terminal controller configured with the common card through a Beidou master control station. The communication protocol may be an RDSS (Radio Determination Satellite Service, beidou short message) protocol.
The control center 11 may generate the first short message information when a triggering condition preset by the air defense disaster prevention alarm control system 10 is reached. The preset trigger condition may be a preset time. The first short message information may include an ID of a normal card configured by the specified terminal controller 12, and an ID of a director card or an ID of a normal card configured by the control center 11. When the Beidou master control station fully incorporates the terminal controllers 12 specified in the first short message information into the first communication packet established by the control center 11, the control center 11 can generate an alarm issuing instruction and send the alarm issuing instruction to the Beidou master control station, the Beidou master control station sends the alarm issuing instruction to the terminal controllers 12 in the first communication packet, after receiving the alarm issuing instruction, the terminal controllers 12 in the first communication packet perform format conversion on the alarm issuing instruction according to the short message format, the alarm issuing instruction after format conversion is output to an alarm, and the alarm receives the alarm issuing instruction after format conversion and issues an alarm according to the alarm issuing instruction after format conversion.
In this embodiment, the total number of the terminal controllers 12 in the first communication packet is not greater than a preset value, for example, the preset value may be 126, that is, the total number of the terminal controllers 12 in the first communication packet is not greater than 126.
In the embodiment of the application, when the air defense disaster prevention alarm control system in the prior art issues the alarm issuing instruction to the terminal controllers from the control center, the problem of false issuing and missed issuing possibly exists due to the fact that the number of the terminal controllers is large and the distribution range is wide, and therefore the alarm issuing instruction cannot be executed in time. In this embodiment, the control center 11 may send the first short message information to the north bucket master control station, instruct the Beidou master control station to bring the terminal controller 12 specified in the first short message information into the first communication packet established by the control center 11, and send the alarm issuing instruction to the terminal controller 12 in the first communication packet through the Beidou master control station. That is, the terminal controller 12 in the first communication packet is the terminal controller 12 specified in the first short message information, and the embodiment of the present application may send the alarm issuing instruction to the specified terminal controller 12, which reduces the probability of false sending and missed sending, and is beneficial for the terminal controller 12 to execute the alarm issuing instruction in time.
In one possible implementation, the target terminal controller 12 is configured to generate second short message information, and send the second short message information to the beidou master station. The second short message information is used for indicating the Beidou master control station to bring other terminal controllers 12 specified in the second short message information into the second communication packet established by the target terminal controller 12.
Wherein the target terminal controller 12 is a terminal controller 12 pre-designated in the first communication packet.
The other terminal controllers 12 are terminal controllers 12 other than the target terminal controller 12.
The target terminal controller 12 is further configured to forward the alarm issuing instruction to the second communication packet through the beidou master station after receiving the alarm issuing instruction.
The terminal controller 12 in the second communication packet is configured to execute the alarm issuing instruction after receiving the alarm issuing instruction.
In the prior art, short message communication generally has two modes of general broadcasting and on-demand broadcasting. The general broadcasting is a function of the command card, and can broadcast a message to all subordinate ordinary cards, and the general broadcasting system structure schematic diagram provided by the embodiment of the application shown in fig. 2 is understood as point-to-multipoint broadcasting communication, and the device equipped with the command card can simultaneously send a message to a plurality of devices equipped with the ordinary cards.
Since the air defense and disaster prevention alarm control requires one-to-many simultaneous transmission of an alarm issuing instruction, the instruction issuing is generally performed by using a general broadcasting method, and the instruction is issued to all terminal controllers at a time.
However, in the existing general broadcasting mode, membership of the command card and the subordinate ordinary card is written in by the Beidou card issuing mechanism when the Beidou communication card is applied, so that a user cannot change, and the expandability of the terminal controller is poor.
In this embodiment, the target terminal controller 12 (the terminal controller 12 pre-designated in the first communication packet) may generate the second short message information, or generate the second short message information when the total number of the terminal controllers 12 in the first communication packet reaches a preset value, where the target terminal controller 12 sends the second short message information to the beidou master station, and after receiving the second short message information, the beidou master station brings other terminal controllers designated in the second short message information into the second communication packet established by the target terminal controller 12. The membership relationship between the control center 11 and the terminal controller 12 can be changed by modifying the ID of the common card of the other terminal controllers 12 specified in the second short message information and the ID of the common card of the terminal controller 12 specified in the first short message information, the target terminal controller 12 (the terminal controller 12 specified in the first communication packet in advance) can also establish a second communication packet, the alarm issuing instruction received by the target terminal controller 12 is forwarded to the terminal controller 12 in the second communication packet through the Beidou master control station, and the target terminal controller 12 can incorporate the other terminal controllers into the second communication packet, so that the expansion of the terminal controller can be flexibly realized.
In this embodiment, the total number of the terminal controllers 12 in the second communication packet is also not greater than the preset value, for example, the preset value may be 126, that is, the total number of the terminal controllers 12 in the second communication packet is not greater than 126.
In this embodiment, the terminal controller specified in advance in the second communication packet may also establish the third communication packet according to the actual number of terminal controllers.
For example, when the air defense and disaster prevention alarm control system 10 includes a control center, as shown in fig. 3, the target terminal controller 12 is a terminal controller a and a terminal controller B, and the preset value is n.
In this embodiment, the second short message information may include the ID of the normal card configured by the specified other terminal controller 12 and the ID of the normal card configured by the target terminal controller 12. In the present embodiment, the other terminal controllers 12 may be terminal controllers 12 other than the target terminal controller 12, or may be terminal controllers 12 other than the first communication packet.
In one possible implementation, there is an overlap of the terminal controllers 12 specified in the first short message information generated by the different control centers 11.
In this embodiment, when the air defense and disaster prevention alarm control system 10 includes a plurality of control centers, the terminal controllers specified in the first short message information generated by the different control centers have overlapping terminal controllers. In the present application, if a certain control center is damaged, and the first short message information cannot be generated or the alarm issuing instruction cannot be generated, the control center of the terminal controller overlapping with the damaged control center may be used as a backup control center. In this application, there may be at least one overlapping terminal controller for every two control centers.
For example, when the air defense and disaster prevention alarm control system 10 includes three control centers, a plurality of groups may be built by using one beidou communication card ID of a beidou satellite No. three, or characteristics of a plurality of groups may be added, and a grouping schematic diagram of the three control centers 11 provided in the embodiment of the present application as shown in fig. 4 may be built, so that it is known that the three control centers are the control center 1, the control center 2 and the control center 3, the three control centers 11 are backup control centers, and the overlapped terminal controllers 12 may be the terminal controller C, the terminal controller D, the terminal controller E and the terminal controller F. If the control center 1 is damaged, the control center 2 and the control center 3 can be used as backup control centers. In the present application, the terminal controllers 12 specified in the first short message information generated by the different control centers 11 are overlapped, and the control centers with the overlapped state are backup control centers, so that the reliability of the air defense and disaster prevention alarm control system 10 can be effectively improved.
In this embodiment, the air defense and disaster prevention alarm control system 10 can be practically used for the control of a multi-stage control center or a multi-backup control center, such as a three-stage air defense and disaster prevention alarm control system in province, city and county, and each stage of air defense and disaster prevention alarm control system has a backup control center, so that the reliability of the air defense and disaster prevention alarm control system 10 is further improved.
