Description

Technical Field

[0002] As an important component of the jammer launch system, the jammer delivery controller mainly provides ignition excitation energy for the jammer. With the rapid development of integrated self-defense systems, the jammer delivery controller is required to meet the dynamic loading, maintenance, and ignition delivery capabilities for intelligent jammers. In particular, the jammer delivery controller is required to have a stacked data communication function, enabling data exchange between the jammer delivery controller and the jammer, and between the jammer delivery controller and the integrated self-defense system. Due to technical problems, traditional jammer delivery controllers do not have this capability. In addition, traditional jammer delivery devices generally adopt a horizontal structure in which the ignition delivery component and the control box are placed separately and interconnected by cables outside the cabin. This has the disadvantages of being large in size and weight, complex ignition line wiring, and difficult to disassemble and maintain. It is difficult to improve the jammer delivery capacity.

[0027] In order to make the purpose, content and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below with reference to the accompanying drawings and examples.

[0028] This embodiment proposes a stacked jammer delivery controller with data communication function, the structure of which is as follows: Figure 1 As shown, it mainly includes a contact interface module 1, an ignition control module 2, a communication processing module 3, and a housing 4. The contact interface module 1 and the ignition control module 2 are installed and connected via two pairs of inter-board electrical connectors, and the ignition control module 2 and the communication processing module 3 are installed and connected via a pair of inter-board electrical connectors. After installation and connection, the entire circuit module is assembled in the housing 4 and fastened with screws.

[0029] The functional relationship between the modules in the jammer delivery controller is as follows: Figure 2As shown, the contact interface module 1 serves as the electrical connection interface between the jammer delivery controller and the jammer; the communication processing module 3 is used to receive warning information from the integrated self-defense system host, generate a jammer delivery strategy, and send it to the ignition control module 2. At the same time, the communication processing module 3 can also receive self-test information from the jammer to identify the jammer type and status; the ignition control module 2 is used to receive the jammer delivery strategy and maintenance instructions from the communication processing module 3, manage the ignition channel, and output the ignition signal; the housing 4 is a structural component of the jammer delivery controller, providing electromagnetic and physical protection for the contact interface module 1, ignition control module 2, and communication processing module 3, and realizing mechanical connection with the carrier aircraft.

[0030] like Figure 3a and 3b As shown, the contact interface module 1 includes a printed circuit board 1-1, an inter-board electrical connector 1-2, an elastic electrical contact 1-3, a protective plate 1-4 and a buffer pad 1-5. The material of the printed circuit board 1-2 is FR4, and the front of the printed circuit board 1-2 is welded with no less than 30 groups of elastic electrical contacts 1-3, with no less than 2 in each group. The back of the printed circuit board 1-1 is welded with electronic components and two inter-board electrical connectors 1-2, and the number of pins of each inter-board electrical connector 1-2 is no less than 40. The protective plate 1-4 is a structural component, which is attached to the front of the printed circuit board 1-1 and is used to protect the printed circuit board 1-1, so that the printed circuit board 1-1 can not only realize the routing of electrical signals, but also withstand the recoil of the jamming bullet transmitted by the elastic electrical contact 1-3, to prevent the printed circuit board 1-1 from being directly affected by the recoil of the jamming bullet and causing circuit damage. A buffer pad 1-5 is installed in the gap between the protection plate 1-4 and the elastic electrical contact 1-3. The buffer pad 1-5 is made of silicone rubber material and can play a buffering and sealing role.

[0031] The front of the ignition control module 2 is welded with two inter-board electrical connectors with no fewer than 40 pins for interfacing with the contact interface module 1; the back of the ignition control module 2 is welded with one inter-board electrical connector with no fewer than 60 pins for interfacing with the communication processing module 3. The ignition control module 2 utilizes a microcontroller and transistor switching circuits to implement an array of no fewer than 30 ignition channels. The array of ignition channels formed by the transistor switching circuits utilizes a passive ignition design, capable of delivering an ignition current of no less than 5A to the jammer output via the contact interface module 1. The microcontroller utilizes a calibrated high-precision crystal oscillator to provide the operating clock, enabling dynamic planning of ignition channels and grouping of each ignition channel. The interval between groups is adjustable, with a step size of no more than 100ms. The ignition control module 2 includes an RS422 communication data link. The microcontroller can communicate data with the communication processing module 3 through the RS422 communication data link, receive and execute the bullet type information and delivery instructions issued by the communication processing module 3, generate an ignition sequence and provide it to the ignition channel corresponding to the specific bullet position, and return the execution result instruction to the communication processing module 3.

[0032] The communication processing module 3 includes two data communication links: serial communication and power line carrier communication. The serial communication data link has two communication modes: RS422 and 1553B. The communication processing module 3 receives warning information from the integrated self-defense system via the 1553B data link. According to the built-in delivery strategy and remaining ammunition management algorithm, it generates a delivery instruction containing the delivery quantity and type of the delivered ammunition, and transmits it to the ignition control module via the RS422 data link. The power line carrier communication link is a two-wire communication method that uses downstream voltage modulation and upstream current modulation. The communication processing module 3 communicates with the jamming projectile via the power line carrier data link, sends status query instructions to the jamming projectile, receives the jamming projectile's return information, extracts the ammunition type, status, and remaining ammunition quantity information from the return information, and timely updates the remaining ammunition management information to generate the delivery strategy.

[0033] Communication processing module 3 includes no fewer than 30 power line carrier signal interfaces. These 30 signal interfaces are connected to ignition control module 2 via inter-board electrical connectors with no fewer than 60 pins. These interfaces are routed via the silkscreen layer on ignition control module 2, ultimately reaching contact interface module 1 via inter-board electrical connectors 1-2. These interfaces correspond to each set of resilient electrical contacts 1-3 on contact interface module 1. Each signal interface group, corresponding to each set of resilient electrical contacts 1-3, contains two channels: Channel A and Channel B. Communication processing module 3 implements data communication and detection of jammers through time-division multiplexing of Channel A and Channel B within each group.

[0034] The communication processing module 3 also includes a loop resistance detection module. Through this module and using the current loop formed by Channel A and Channel B in each group, the loop resistance of the jamming bomb can be detected. The resistance detection circuit contains two constant current sources no greater than 30mA, which are switched by solid-state relays to detect the loop resistance of the jamming bomb in the 30 signal channels. When the constant current source direction is from Channel A to Channel B, the forward resistance between the power contacts A and B is detected. When the constant current source direction is from Channel B to Channel A, the reverse resistance between the power contacts A and B is detected. When the loop is loaded with an intelligent jamming bomb, the forward resistance and reverse resistance between the power contacts A and B are significantly different. When the loop is loaded with a non-intelligent jamming bomb, the forward resistance and reverse resistance between the power contacts A and B are equal.

[0035] like Figures 4a-4c As shown, the shell 4 is injection molded with reinforced carbon fiber material PEEK composite material, and metal inserts are used to reinforce the connection parts for installing bolts; the inner wall of the shell 4 is evenly coated with a layer of copper-clad silver composite conductive paint to form an electromagnetic shielding cavity.

[0036] When the jammer delivery controller of the present invention is in operation, the communication processing module 3 is powered on and first connects to the jammer's resistance detection channel. The resistance of each jammer at each bomb position is tested twice, from channel A to channel B and then from channel B to channel A. If the resistance values of the two tests meet pre-defined rules, the function is switched to the carrier data link, and a round-robin query is performed on the jammers mounted on the carrier data bus, actively obtaining information on the type and quantity of jammers mounted on the carrier data bus. When the communication processing module 3 receives target warning information sent from the integrated self-defense system via the 1553B data bus, it performs data analysis and formulates a jammer delivery strategy. The strategy includes information such as the type, quantity, and delivery interval of the jammers to be delivered. The communication processing module 3 sends the delivery strategy to the ignition control module 2 via the RS422 bus. The ignition control module 2 generates an ignition sequence and distributes ignition energy to the contact interface module 1 to ignite the jammer.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
