[0024] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the 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. In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

The terms "comprises", "comprising", "includes", "including" and the like are synonymous with the term "containing" and are used in the sense of "including, but not limited to". For example, a process, method, article, or apparatus that comprises a list of steps or elements is not necessarily limited to the listed steps or elements, but can include additional or other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

[0026] As shown in Figure 1 The first embodiment of the present application proposes a continuous launch missile control device, for example, including: a control circuit board and a core circuit board and a timing circuit board electrically connected to the control circuit board.

[0027] The core circuit board, for example, adopts a DSP+FPGA architecture, as a minimum processing system, which can expand 2-way CAN bus, 8-way RS422 bus, 1-way 100M network port, 1-way AD acquisition channel, 2-way storage circuit, and 200-way general IO pin in cooperation with the control circuit board.

[0028] The core circuit board is a minimum processing system, which is standardized, universalized, and serialized, and can be widely applied in the field of information processing system and test control. The main design contents are as follows:

[0029] The core chip, for example, adopts DSP6748F and FPGA Spartan-6, which can be replaced and upgraded according to the system needs, and cooperates with RAM and ROM to enhance the information processing capability of the minimum processing system. The working voltage is designed according to 3.3V, for example, the core circuit board converts the 3.3V voltage into the power supply voltage required by the core chip, simplifies the secondary design of the peripheral power supply circuit in application, and the secondary design does not need to care about the power-on sequence of the core chip. The core circuit board includes the design of secondary reset circuit, which makes the software of the core chip normally loaded, avoids the possibility of software runaway, and improves the reliability. The core circuit board selects appropriate board-level connectors to lead out the corresponding function pins of the core circuit board, including power supply, BOOT, JTAG, EMIF bus, communication, general IO, etc., which is convenient for secondary design. The core circuit board, for example, also designs a metal clamping edge in the periphery of the printed board to enhance the strength of the printed board, sets mounting holes around, and is fixed through studs and corresponding expansion boards to improve the environmental adaptability.

[0030] The control circuit board cooperates with the timing circuit board to realize power distribution / power cut-off control and timing control of the load. The control circuit board is the control core of the control and sending device, which receives the command sent by the upper computer, analyzes the command, and decides whether to send the corresponding control instruction according to the load state, the control state, the analog quantity state, and the like, and returns the result to the upper computer, while storing all information generated in the information interaction. The control board includes a communication module, an analog quantity sampling module, a storage module, a switching quantity control module, a power circuit module, and the like, and the main design contents are as follows:

[0031] In one embodiment, the communication module includes, for example, a CAN communication module, an RS422 communication module, and a network port communication module. Specifically, for example, the MAC interface led out by the core circuit board DSP6748F cooperates with the network port PHY chip, and the RJ45 network port connector with a transformer expands the 100M network port. The control and sending device receives the control command of the upper computer in real time through the network port, and feeds back the state of the control and sending device and the control command execution result to the upper computer. The general I / O interface led out by the core circuit board FPGA cooperates with the SPI-to-CAN controller chip, and the CAN transceiver with isolation expands two-way CAN bus. One-way CAN bus is reserved, and the other-way CAN bus is connected to a controller. The part of the upper computer control instruction analyzed is forwarded to the controller through the CAN bus, and the state fed back by the controller is received through the CAN bus. After the message is analyzed, it is fed back to the upper computer. The general I / O interface led out by the core circuit board FPGA cooperates with the serial port isolation transceiver with isolation to expand 8-way RS422 bus. Four-way RS422 bus is reserved, and the other four-way RS422 bus is connected to four loads with the same state. The part of the upper computer control instruction analyzed is forwarded to the load control system through the RS422 bus, and the state fed back by the load control system is received through the RS422 bus. After the message is analyzed, it is fed back to the upper computer.

[0032] In one embodiment, the EMIF bus led out by the core circuit board DSP6748F cooperates with the CPLD, the A / D controller, the operational amplifier, and the isolation amplifier to expand the analog quantity sampling circuit. As shown in Figure 2 the appropriate voltage division network ratio is determined according to the analog quantity input condition, the A / D controller input requirement, and the amplification requirement of the isolation amplifier circuit, and the analog switch is used for channel selection when the analog quantity sampling channels are more. The analog quantity sampling module detects the input voltage state of the control and sending device, the power supply voltage state of the load bus, and the power supply voltage leakage state of the load bus to the machine shell according to the part of the upper computer control instruction, judges the state of the control and sending device and the load, and feeds back the result to the upper computer in real time.

[0033] In one embodiment, the EMIF bus of the core circuit board DSP6748F is extended to cooperate with the CPLD to extend the output control channel and the input acquisition channel. As shown in Figure 3 the output control signal is raised by a level converter to improve its driving capability, effectively driving the relay in the timing circuit board, and the input is isolated by an optical coupler to collect the state of the relay after the action. The control device sends out control signals according to part of the host computer control instructions, controls the relay to act accordingly, and at the same time, collects and judges the state in real time and feeds back to the host computer.

[0034] In addition, the SATA interface of the core circuit board DSP6748F is extended to cooperate with the mSATA storage chip to expand the storage capacity of not less than 16G. The SD card interface of the core circuit board DSP6748F is extended to cooperate with the TF storage chip to expand the storage capacity of not less than 16GB. The two kinds of storage are backup to each other, and the data generated in the working process of the control device is recorded, which is convenient for troubleshooting problems in the subsequent use process.

[0035] Because the control device needs to work stably in the system, the working power supply of the control device and the load working power supply are distinguished through the power supply circuit module to avoid the load power-on instant pulling down the working voltage of the control device, causing the control device to work abnormally. After the power supply enters the control device, one way is connected to the control board as the working power supply of the control device, and the other way is connected to the timing circuit board as the timing control power supply of the control device. After the power supply enters the control board, voltage stabilizing measures are taken or a wide range input power supply module is selected to obtain stable working power supply. According to the working needs of the control board, the input power supply is converted into the corresponding working voltage, including commonly used 5V, 3.3V, and A / D chip commonly used isolation ±15V, analog switch commonly used isolation ±5V, etc., to ensure the reliable work of the control device.

[0036] The timing circuit board is the execution core of the four-in-one launch control device. The timing circuit board controls the on / off of the relay according to the switch quantity control signal of the control board, and at the same time, the on / off state of the relay is fed back to the control board as an input signal. The control board monitors the state of the timing circuit board in real time. The timing circuit board includes power on / off control module, timing control module, etc., and the main design idea is as follows:

[0037] The power-on / off of the control device is controlled by the control combination panel switch of the control device, and appropriate panel switch is selected according to the voltage and current requirements of the control device to control the power-on / off, which is the power supply switch of the control device. According to the power supply requirements of the load control system, analog battery power supply, rudder system power supply and the like, the time sequence circuit board selects appropriate relays as the power-on / off switch of the load power supply. When selecting the power-on / off relay, attention should be paid to the redundancy of the rated voltage and current, as well as the transient voltage and current of the load power supply, to ensure stable and reliable work during application.

[0038] Generally, all the time sequences of the load are pulse large current signals, and the control device selects appropriate relays according to the time sequence requirements of the load to control the time sequence. Specifically, the time sequence control module is a safety control mode of three-stage relay series connection, combined with Figure 4 As shown in the figure, the positive output end of the first-stage relay is connected to the time sequence control power supply of the control device, the negative output end of the first-stage relay is connected to the positive output end of the second-stage relay, the negative output end of the second-stage relay is connected to the positive output end of the third-stage relay, and the negative output end of the third-stage relay is connected to the corresponding input end of the load. The main time sequence control conditions are as follows:

[0039] The first stage is the total control switch. When the control device is powered on and the upper computer confirms that the load state is normal and has the launch condition, the upper computer instructs the control device to unlock the first-stage total control switch, and the control board judges whether the total control switch is normally opened, and feeds back to the upper computer to judge whether to continue to execute the time sequence control; the second stage is a single electric control switch of multiple loads (for example, 4-way), and the upper computer confirms that the first-stage total control switch is normal. Under the condition that the upper computer instructs the control device to unlock the electric control switch, the control board judges whether the electric control switch is normally opened, and feeds back to the upper computer to judge whether to execute the time sequence control; the third stage is a parallel battery activation, ignition, cover opening and pin pulling switch, and the upper computer confirms that the second-stage switch is normal. Under the condition that the upper computer instructs the control device to unlock the cover opening switch, pin pulling switch, battery activation switch and ignition switch in sequence, the state of the cover opening, pin pulling, battery activation and ignition is monitored in real time, and the load is safely and reliably launched.

[0040] In one embodiment, the power-on / off control cannot simultaneously power on each load, at most two loads can be powered on at the same time, and the load bus voltage is monitored in real time to prepare for launch. The software is designed to be mutually exclusive, and the monitoring condition is uploaded back to the upper computer to avoid misuse of the upper computer during use, which may cause safety hazards.

[0041] In one embodiment, the total control switch of the launch control device opens the total control switch and monitors the switch state in real time under the condition that all the launch states of the four launchers are normal; under the premise that the total control switch is opened, only the electric control switch of one of the launchers can be opened and its switch state is monitored in real time, and the electric control switch of the launcher is mutually exclusive with the electric control switches of the other three launchers. Under the premise that the total control switch and the electric control switch are opened, only the cover opening switch of the launcher whose electric control switch is opened can be opened, and the subsequent pull pin switch, battery activation switch and ignition switch are opened in sequence, and the sequence cannot be changed, and only one of the cover opening, pull pin, battery activation and ignition can be opened at a time. In this way, the accuracy of the operation sequence can be further ensured, the misoperation can be avoided, and a guidance direction for the development and improvement of the reliability of the launch control device is provided.

[0042] In addition, as shown in Figure 5 The second embodiment of the present application proposes a multiple launch missile launch control system, for example, including the multiple launch missile launch control device as described in the first embodiment, and a host computer, an external controller and a plurality of control loads which are communicatively connected to the multiple launch missile launch control device. The host computer 31 mentioned above is, for example, a personal computer, a handheld device, a portable device, a tablet device, a multi-processor system, a microprocessor-based system, an editable consumer electronic device, a network PC, a minicomputer, a mainframe computer, or a distributed computing environment including any of the above systems or devices, and the like.

[0043] The multiple launch missile launch control device includes, for example, a plurality of external interfaces and a power supply total switch as a control combination, wherein S1 is the power supply total switch of the launch control device; X1 is the power supply input interface of the launch control device and the communication interface (CAN bus) of a certain controller; X2 is the communication interface (network port) between the launch control device and the host computer; X3A to X3D are the power distribution control, timing control, state acquisition and communication interface (RS422) between the launch control device and the loads; X4 is a reserved interface of the launch control device, which is convenient for subsequent expansion application. The control combination selects appropriate switches and connectors that are resistant to salt mist and water according to the use environment on water, and can be reliably used in harsh environments.

[0044] It is worth mentioning that the structure and function of the specific multiple launch missile launch control device can refer to the content described in the first embodiment, and will not be described in detail here for the sake of brevity, and the multiple launch missile launch control system provided in this embodiment has the same beneficial effects as the multiple launch missile launch control device provided in the first embodiment.

[0045] Further, the third embodiment of the present application also provides a method for controlling the launch of a multiple-launch missile, for example, comprising steps S1-S3. In step S1, after power-on, a first control instruction is received from a host computer, a master control switch is unlocked according to the first control instruction, and the open state of the master control switch is fed back to the host computer, so that the host computer determines whether to execute a control time sequence, and sends a second control instruction when the determination is positive. In step S2, any load control switch in series with the master control switch is unlocked according to the second control instruction, the open state of the load control switch is fed back to the host computer, so that the host computer determines whether to execute a control time sequence, and sends a third control instruction when the determination is positive. In step S3, a cover switch, a pin switch, a battery activation switch, and an ignition switch in series with the load control switch are sequentially unlocked according to the third control instruction, so as to realize the launch of a corresponding load.
