Abstract

A launch control system relates to a method and apparatus for launch control packet processing that is provided in the launch control system and configured to allow interworking between a plurality of firing control systems and the launch control system. The launch control system comprises a plurality of operation equipments, a system control device, and control the plurality of operation equipments, a launch control packet processing unit, a control signal distribution device, and a status display device.

First claim

What is claimed is:

1. A launch control system comprising:
a plurality of operation equipments used for launch control of a guided weapon;
a system control device configured to communicate with a plurality of firing control systems for controlling a firing sequence of the guided weapon and a plurality of test equipments, and control the plurality of operation equipments;
a launch control packet processing unit configured to generate, when an interworking start event linked to one of the plurality of firing control systems begins, one or more first packets to be transmitted to said one of the firing control systems and one or more second packets that are expected to be received from said one of the firing control systems based on an interface control document (ICD), and configured to analyze, when a third packet received by the system control device and said one or more second packets are compared and the third packet is determined to match at least one of said one or more second packets, information included in the third packet to allow the system control device to transmit said one or more first packets to the firing control systems based on the information, or allow the system control device to control the operation equipments based on the information;
a control signal distribution device configured to interface signals between the system control device and the test equipments; and
a status display device configured to display launch control information of the system control device and event information.

2. A launch control packet processing apparatus built in in a launch control system, comprising:
a packet generation unit configured to generate, when an interworking start event linked to a predetermined firing control system occurs, one or more first packets to be transmitted to the firing control system and one or more second packets that are expected to be received from the firing control system based on an interface control document (ICD) in which formats of packets to be transmitted to and received from the firing control system and an order of the packets to be transmitted to and received from the firing control system are previously defined;
a packet comparison unit configured to compare a third packet received from the firing control system and said one or more second packets; and
a packet processing unit configured to analyze, when the third packet is determined to match at least one of said one or more second packets, information included in the third packet and, based on the information, allow the launch control system to perform operations defined in the ICD.

3. The launch control packet processing apparatus of claim 2 , wherein the packet processing unit analyzes, when the third packet is determined to match at least one of said one or more second packets, information included in the third packet and transmits a packet that is defined in the ICD as a packet to be transmitted after the third packet is received among said one or more first packets to the launch control system.

4. The launch control packet processing apparatus of claim 2 , wherein the packet processing unit analyzes, when the third packet is determined to match at least one of said one or more second packets, information included in the third packet and operates operation equipments built in the launch control system based on contents defined in the ICD.

5. The launch control packet processing apparatus of claim 2 , wherein the packet processing unit transmits a packet re-transmission request message to the launch control system when there is no packet matched with the third packet among said one or more second packets.

6. The launch control packet processing apparatus of claim 2 , wherein the packet processing unit outputs an error message when there is no packet matched with the third packet among said one or more second packets.

7. A launch control packet processing method performed by one or more processors, comprising:
generating, when an interworking start event linked to a predetermined firing control system occurs, one or more first packets to be transmitted to the firing control system and one or more second packets that are expected to be received from the firing control system based on an interface control document (ICD) in which formats of packets to be transmitted to and received from the firing control system and orders of the packets to be transmitted to and received from the firing control system are defined in advance;
comparing a third packet received from the firing control system with said one or more second packets; and
analyzing, when the third packet is determined to match at least one of said one or more second packets, information included in the third packet and, based on the information, allowing the launch control system to perform operations defined in the ICD.

8. The launch control packet processing method of claim 7 , wherein the allowing the launch control system to perform operations defined in the ICD includes:
analyzing, when the third packet is determined to match at least one of said one or more second packets, information included in the third packet and transmitting to the firing control system a packet that is defined in the ICD as a packet to be transmitted after the third packet is received among said one or more first packets.

9. The launch control packet processing method of claim 7 , wherein the allowing the launch control system to perform operations defined in the ICD includes:
analyzing, when the third packet is determined to match at least one of said one or more second packets, information included in the third packet and allowing operation equipments built in the launch control system to operate based on contents defined in the ICD.

10. The launch control packet processing method of claim 7 , wherein the allowing the launch control system to perform operations defined in the ICD includes:
transmitting a packet re-transmission request message to the launch control system when there is no packet matched with the third packet among said one or more second packets.

11. The launch control packet processing method of claim 7 , wherein the allowing the launch control system to perform operations defined in the ICD includes:
outputting an error message when there is no packet matched with the third packet among said one or more second packets.

12. A non-transitory computer-readable recording medium storing instructions thereon, the instructions when executed by a processor causing the processor to:
generate, when an interworking start event linked to a predetermined firing control system occurs, one or more first packets to be transmitted to the firing control system and one or more second packets that are expected to be received from the firing control system based on an interface control document (ICD) in which formats of packets to be transmitted to and received from the firing control system and orders of the packets to be transmitted to and received from the firing control system are defined in advance;
comparing a third packet received from the firing control system with said one or more second packets; and
analyze, when the third packet is determined to match at least one of said one or more second packets, information included in the third packet and, based on the information, allowing a launch control system to perform operations defined in the ICD.
