Description

Technical Field

[0001] The present invention belongs to the technical field of avionics equipment, and particularly relates to a control system for a general airborne passive interference device. Background Art

[0002] The airborne passive interference dispensing device is applied to electronic warfare equipment. The traditional control architecture of the airborne passive interference dispensing device consists of a display and control box (control box), a sequencer, and a transmitter. The transmitter is filled with passive interference equipment. The working principle of the control architecture is as follows: after receiving the guidance command sent by the superior, the display and control box comprehensively calculates the emission information, and sends it to the sequencer through the communication bus. The sequencer controls the ignition output according to the emission information, and the ignition output signal is output to the corresponding ammunition position of the corresponding transmitter through the emission cable to ignite and dispense the interference equipment on this ammunition position. This control architecture has many control links, complex control cables and many control signals, resulting in relatively low overall working reliability indicators of the equipment, and being easily interfered by the complex electromagnetic field environment inside or outside the aircraft, resulting in abnormal operation, low cost performance, and inability to expand the number of emission resources. Summary of the Invention

[0003] In view of this, the present invention provides a control system for a general airborne passive interference device, which can solve the technical problems of the existing control architecture of the airborne passive interference device having many control links and being easily interfered to cause abnormal operation.

[0004] The technical solution of the present invention is implemented as follows:

[0005] A control system for a general airborne passive interference device includes:

[0006] A dispensing controller, a plurality of transmitters, and a bus; the dispensing controller is connected to the plurality of transmitters through the bus;

[0007] The dispensing controller is composed of a main control module, a communication module, and a power module. The main control module is used for operation, information analysis, interference resource control management, and combat function decision-making processing. The communication module is used for communication bus matching, networking, and real-time status monitoring. The power module is used for receiving the aircraft power supply and processing it into a working power supply that can provide power for various modules of the control system;

[0008] The plurality of transmitters are respectively used for transmitting interference resources to their respective corresponding targets.

[0009] Preferably, the dispensing controller collects in real time the indication information and status information of the carried aircraft platform. When receiving a mission command, according to the passive interference dispensing guidance information, the carrier centroid balance dispensing strategy, and the interference resource balanced consumption strategy of the carried aircraft platform, combined with the working status of the dispensing controller and the loading situation of interference resources in each emitter, it automatically calculates and generates an interference resource emission information command, and sends the interference resource emission information command to the corresponding emitter respectively; the passive interference dispensing guidance information includes the dispensing group number of interference resources, the group interval time, the number of projectiles in each group, single-shot or double-shot, and the projectile interval; the interference resource emission information command includes the emitter ID number, the type of interference resource, the emission quantity, and the emission interval.

[0010] Preferably, the carrier centroid balance dispensing strategy means that when the aircraft platform carried by the dispensing controller receives a mission command, it obtains the distribution situation of interference resources possessed by the aircraft platform, analyzes the mission command, estimates the consumption speed of various interference resources and the reserved quantity of interference resources, thereby determining the impact of interference resource consumption on the centroid of the aircraft platform. With the goal of maintaining the balance of the aircraft centroid, it determines the emission timing of each emitter, and thus generates an interference resource emission information command;

[0011] The interference resource balanced consumption strategy means that when the same interference resources are loaded in different emitters on both sides of the aircraft axis or the same interference resources are loaded in different emitters on one side of the aircraft axis, during the calculation and allocation, when consuming the same type of interference resources, they are evenly and equally consumed from different emitters.

[0012] Preferably, in the interference resource emission information command, the emission quantity of the emitter emitting interference resources is determined by the following calculation formula:

[0013] S(t) = S1 / N + σ(ID, ΔS, t)

[0014] Where S1 is the quantity of interference resources required to be dispensed in a single group in the passive interference dispensing guidance information, N is the number of emitters, ID is the emitter ID number, ΔS is the remaining quantity to be allocated after the average allocation of each emitter, t is the current time used to associate the current status of each jammer and interference resource, σ(ID, ΔS, t) is the calculation and allocation function, and S(t) is the interference resources that the emitter corresponding to ID should dispense.

[0015] Preferably, the bus is a dual-redundancy CAN bus. The dual-redundancy CAN bus connects each emitter to the dispensing controller respectively, forming an equilateral star bus network centered on the dispensing controller; the calculation formula for the resistance value R of the terminal matching resistor on each emitter is as follows:

[0016] R = N × 60Ω + Δ(L, ρ, N)

[0017] Among them, N is the number of transmitters, Δ(L, ρ, N) is the fine-tuning function of the interruption matching resistance value obtained based on historical data, L is the communication distance, ρ is the communication baud rate, N is the number of transmitters, and each transmitter on the bus uses a communication terminal matching resistance with a resistance value of R; the bus uses the voltage difference between the differential signal pairs, namely signal CAN_H and signal CAN_L, to judge the bus level and then transmit and receive communication data. At the same time, a hot backup redundancy design is adopted for the key signals CAN_H and CAN_L. Two pairs of key signals CAN_H and key signal CAN_L work simultaneously to control the delivery controller and all transmitters to send and / or receive data on the two CAN buses, and the data sent and / or received on each bus is different; a dual CAN data fusion algorithm is adopted to sort, abnormally integrate and process the dual-channel data provided by the two CAN buses; the formula of the dual CAN data fusion algorithm is as follows:

[0018]

[0019] Among them, the D(t) function is used to judge the repeatability of the data sent by the two channels. If they are not repeated, all the data of the two signals are received and processed. If the data is repeated, the time sequence is compared. D 1,t1 is the data received on the first CAN bus, D 2,t2 is the data received on the second CAN bus, t is the current time, and t1 is the time recorded when the data D 1,t1 is sent, and t2 is the time recorded when the data D 2,t2 is sent; the T(t) function is used to compare t1 and t2 to judge whether they are in the same time window, and data fusion is performed according to the judgment result; the S(t) function is used to fuse the data Dt1 and Dt2 of the two channels to form the final valid data;

[0020] When a certain channel malfunctions, the other channel can work normally.

[0021] Preferably, after receiving the interference resource emission information instruction, each transmitter sequentially guides the tube positions of the transmitters to output a high level with a preset pulse width in sequence according to the types of interference resources, the number of emissions, and the emission interval requirements specified in the interference resource emission information instruction for ignition and emission, stimulates the interference resources on the tube positions for delivery, implements passive interference, and refreshes the status of all interference resources in real time, and reports the delivery status, delivery result, remaining ammunition quantity, and transmitter status to the delivery controller;

[0022] The interior of the transmitter further includes an intelligent launch module, which has the functions of ignition launch, identification of different interference resources, and data binding; based on the two-wire communication bus technology, the intelligent launch module can communicate with the loaded interference resources without changing the form of the ignition contact interface of the transmitter; the data binding function can load combat parameters and the working state of the transmitter.

[0023] Advantages:

[0024] (1) Based on the distributed control principle, the present invention adopts an intelligent and modular design. The control architecture has few hardware resources, simplified control cables and signals, the types and quantities of launch resources can be freely configured, and it has strong anti-electromagnetic interference ability.

[0025] (2) The present invention can meet the installation requirements of small, medium, and large aircraft platforms.

[0030] 1, delivery controller; 2, transmitter; 3, intelligent bus. Detailed Embodiments

[0031] The following are specific embodiments of the present invention with reference to the drawings and examples for detailed description.

[0032] As Figure 1 shown, the present invention provides a control system for general airborne passive interference equipment, including a delivery controller, multiple transmitters, and a bus; the delivery controller is connected to multiple transmitters through the bus;

[0033] The dispensing controller consists of a main control module, a communication module, and a power supply module. The main control module is used for operation, information analysis, interference resource control management, and combat function decision-making. The communication module is used for communication bus matching, networking, and real-time status monitoring. The power supply module is used to receive the power supply of the carrier aircraft and process it into a working power supply that can be provided for various modules of the control system.

[0034] The multiple emitters are respectively used to emit interference resources to their corresponding targets.

[0035] Further, the dispensing controller collects the indication information and status information of the aircraft platform it carries in real time. When receiving a mission command, according to the passive interference dispensing guidance information of the aircraft platform it carries, the centroid balance dispensing strategy of the carrier aircraft, and the interference resource balance consumption strategy, combined with the working state of the dispensing controller and the loading situation of interference resources of each emitter, it automatically calculates and generates an interference resource emission information command, and sends the interference resource emission information command to the corresponding emitter respectively. The passive interference dispensing guidance information includes the number of dispensing groups of interference resources, the group interval time, the number of projectiles in each group, single-shot or double-shot, and the projectile interval. The interference resource emission information command includes the emitter ID number, the type of interference resource, the emission quantity, and the emission interval.

[0036] Further, the centroid balance dispensing strategy of the carrier aircraft means that when the aircraft platform carried by the dispensing controller receives a mission command, it obtains the distribution situation of interference resources of the aircraft platform, analyzes the mission command, estimates the consumption speed of various interference resources and the reserved quantity of interference resources, determines the impact of interference resource consumption on the centroid of the aircraft platform, and takes maintaining the centroid balance of the aircraft as the goal to determine the emission timing of each emitter, so as to generate an interference resource emission information command.

[0037] The interference resource balance consumption strategy means that when the same interference resources are loaded on different emitters on both sides of the aircraft central axis or the same interference resources are loaded on different emitters on one side of the aircraft central axis, during the calculation and allocation, the same type of interference resources are consumed evenly and equally from different emitters.

[0038] Further, in the interference resource emission information command, the emission quantity of the emitter emitting interference resources is determined by the following calculation formula:

[0039] S(t) = S1 / N + σ(ID, ΔS, t)

[0040] Where S1 is the number of interference resources required to be delivered in a single group in the passive interference delivery guidance information, N is the number of transmitters, ID is the transmitter ID number, ΔS is the remaining quantity to be allocated after the average allocation of each transmitter, t is the current time used to associate the current status of each jammer and interference resource, σ(ID, ΔS, t) is the solution allocation function, and S(t) is the interference resource that the transmitter corresponding to ID should deliver.

[0041] Further, the bus is a dual-redundant CAN bus. The dual-redundant CAN bus connects each transmitter to the delivery controller respectively, forming an equilateral star bus network centered on the delivery controller; the calculation formula for the resistance value R of the terminal matching resistor on each transmitter is as follows:

[0042] R = N × 60Ω + Δ(L, ρ, N)

[0043] Where N is the number of transmitters, Δ(L, ρ, N) is the fine-tuning function of the interruption matching resistor value based on the actual communication engineering experience of the bus, L is the communication distance, ρ is the communication baud rate, and N is the number of transmitters. Each transmitter on the bus uses a communication terminal matching resistor with a resistance value of R, which can ensure the stability of the signal on the bus and the reliable communication between the delivery controller and all transmitters; the bus uses a differential signal pair, that is, the voltage difference between signal CAN_H and signal CAN_L to judge the bus level and then transmit and receive communication data. In engineering applications, the twisted pair technology is adopted, so that the bus has strong anti-electromagnetic and noise interference capabilities, high real-time performance, and high reliability. At the same time, a hot backup redundancy design is adopted for the key signals CAN_H and CAN_L. Two pairs of key signals CAN_H and key signals CAN_L work simultaneously to control the delivery controller and all transmitters to send and / or receive data on the two CAN buses. The data sent and / or received on each bus is different; a dual-CAN data fusion algorithm is adopted to sort, abnormally integrate, and process the dual-channel data provided by the two CAN buses; the formula of the dual-CAN data fusion algorithm is as follows:

[0044]

[0045] Where the D(t) function is used to judge the repeatability of the data sent by the two channels. If they are not repeated, the data of both signals are received and processed. If the data is repeated, the timing comparison is carried out. D 1,t1 is the data received on the first CAN bus, D 2,t2 is the data received on the second CAN bus, t is the current time, t1 is the time recorded when the data D 1,t1 is sent, and t2 is the data D 2,t2The time recorded when sent; The T(t) function is used to compare t1 and t2 to determine whether they are in the same time window, and data fusion is performed according to the judgment result; The S(t) function is used to fuse the data Dt1 and Dt2 of the two channels to form the final valid data;

[0046] When a certain channel malfunctions, the other channel can work normally.

[0047] Further, after each transmitter receives the interference resource emission information instruction, according to the types of interference resources, emission quantities, and emission interval requirements specified in the interference resource emission information instruction, it sequentially guides the tube positions of the transmitter to output high-level signals with a preset pulse width in sequence for ignition and emission, stimulates the interference resources on the tube positions for release, implements passive interference, and refreshes the status of all interference resources in real time, reporting the release status, release result, remaining ammunition quantity, and transmitter status to the release controller;

[0048] The transmitter also includes an intelligent emission module inside, which has the functions of ignition and emission, as well as the identification and data binding functions for different interference resources; The intelligent emission module, based on the two-wire communication bus technology, can communicate with the release controller without changing the form of the ignition contact interface of the transmitter; The data binding function can load combat parameters and the working status of the transmitter.

[0049] The present invention provides a specific embodiment of a general airborne passive interference equipment control system.

[0050] In this embodiment, when the release controller is working, it collects, receives, and manages in real time the status information of the "passive interference release button" (button activated or not activated), the hardware and soft flag status information of the aircraft landing gear (aircraft landed or retracted), the status information of the "passive interference emergency emission button" (button activated or not activated), the control status instruction information (setting the working mode, release method, fire compatibility switch, etc. of this equipment), and the approach status information (aircraft approaching or not approaching) of the aircraft platform it carries, and receives and manages the interference resource status information (including: types, status, and quantities of interference resources) and working status information (normal or specific fault information) sent by all transmitters. When there is a work task, according to the passive interference release guidance information of the aircraft platform (including information such as the number of release groups of a certain type of interference resource, group interval time, number of ammunition per group, single-shot or double-shot, ammunition interval, etc.), based on the centroid balance release strategy of the carrier aircraft and the principle of balanced consumption of interference resources, combined with the working status of this equipment and the loading situation of interference resources in each transmitter, after comprehensive decision-making and automatic calculation, an interference resource emission information instruction (including: transmitter ID number, types of interference resources, emission quantity, emission interval, etc. information) is generated;

[0051] The centroid balance of the carrier aircraft is an important guarantee and requirement for flight stability, maneuverability, and safety during the dynamic processes of all aircraft platforms. The carrier aircraft centroid balance release strategy plays an important role in controlling the centroid balance of the carrier aircraft, ensuring that the centroid remains in an appropriate position during the release process of interference resources. The factors considered when implementing the carrier aircraft centroid balance release strategy include:

[0052] (1) Distribution of interference resources. When there are work tasks, the interference resources carried by this equipment are in a dynamic consumption process. Different distribution situations of the remaining interference resources will have different impacts on the centroid of the aircraft. Therefore, it is necessary to consider the actual distribution of interference resources to calculate and formulate appropriate interference resource emission information;

[0053] (2) Consumption of interference resources. The guidance information for each batch of passive interference releases consumes different amounts of various interference resources. During the consumption process, the centroid of the aircraft will change. This strategy needs to adopt the priority of evenly distributing among each transmitter, followed by symmetric distribution on both sides of the aircraft, and finally dynamic distribution adjustment to maintain the balance of the aircraft centroid;

[0054] (3) Reserved interference resources. Reserved interference resources are used for the aircraft to perform emergency tasks and are default set in several transmitters. During the solution and distribution process of the centroid balance release strategy, the reservation situation of each transmitter needs to be considered, and the emission information of each transmitter should be reasonably distributed to ensure both the normal execution of the task and the balance of the aircraft centroid as much as possible.

[0055] The principle of balanced consumption of interference resources means that when the same interference resources are loaded in different transmitters on both sides of the aircraft or the same interference resources are loaded in different transmitters on one side of the aircraft, during the comprehensive solution and distribution, when consuming the same type of interference resources, try to consume them evenly and equally from different transmitters, rather than consuming the interference resources in a certain transmitter first and then consuming the interference resources in another transmitter, reducing the probability that the loaded interference resources cannot be used after a certain transmitter fails and improving the utilization rate of interference resources.

[0056] A typical single-group comprehensive decision automatic solution formula for a certain type of interference resource is:

[0057] S(t) = S1 / N + σ(ID, ΔS, t)

[0058] Where S1 is the quantity of interference resources required to be released in a single group in the guidance information for passive interference release, N is the number of transmitters, ID is the transmitter ID number, ΔS is the remaining quantity to be distributed after the average distribution of each transmitter, t is the current time used to associate the current equipment and the state of interference resources, σ(ID, ΔS, t) is the core function of solution and distribution, and S(t) is the interference resources that should be released by this ID transmitter.

[0059] The comprehensive decision-making automatic solution of the present invention is a calculation method for the allocation of each transmitter when the delivery guidance information is a single group. When the delivery guidance information is multiple groups, this formula needs to be called multiple times to meet the task requirements. This method is applicable to all passive interference devices equipped with this architecture control system and is a general, effective, and streamlined interference resource calculation and allocation method for each aircraft platform.

[0060] To solve the problem that traditional control cables are vulnerable to interference from complex electromagnetic field environments inside or outside the aircraft, resulting in signal anomalies and low equipment working reliability indicators, and combining the engineering characteristics of short laying distances, equal lengths of the same type, and small cable spacings for control signal cables on all small, medium, and large aircraft platforms, the present invention designs a dual-redundant CAN custom intelligent bus cable based on the field communication bus CAN bus. The CAN bus is a communication bus that can ensure signal arrival, with characteristics such as strong anti-interference ability, high communication rate, easy networking, and strong communication node expansion ability. It is very suitable for short-distance communication and complex electromagnetic interference environments. In this intelligent bus, the two pairs of CAN bus signals CAN_H and CAN_L are laid using a twisted pair process, and the remaining signals are discrete level signals, all of which are high-level effective. Through a large number of tests, it is fully verified that this intelligent bus has extremely strong anti-complex high-field electromagnetic interference ability.

[0061] To solve the problem that traditional control architectures cannot freely configure the types and quantities of interference resources, the intelligent bus of the present invention connects the delivery controller and all transmitters to form an equilateral star-shaped bus network centered on the delivery controller. By adjusting the terminal matching resistors on each transmitter, networking communication can be achieved. Theoretically, the maximum number of transmitters based on this communication network can be expanded to 110, and in actual engineering applications, the number of transmitters can be expanded to at least 20 under the communication rate requirements of 115200bps and above, meeting the installation requirements of various aircraft platforms. According to the theoretical calculation of the CAN bus star topology network engineering application, the calculation formula for the resistance value R of the terminal matching resistor on each transmitter is as follows:

[0062] R = N × 60Ω + Δ(L, ρ, N)

[0063] To further improve the reliability of the control system, combined with the characteristics of small communication data volume and low communication rate requirements of this control system, the intelligent bus of the present invention adopts a hot backup redundancy design for the key signals CAN_H and CAN_L. The two CAN bus signals work simultaneously. The delivery controller and all transmitters on the control system send and receive data on both CAN buses at the same time. A dual-CAN data fusion algorithm is used to automatically sort, abnormally integrate, and process the dual-channel data. When a certain channel works abnormally, the other signal can still ensure normal operation. Compared with the traditional cold backup of channels with abnormal channel switching, this method can improve the reliability of the control system and ensure the real-time nature of communication data. The dual-CAN data fusion algorithm formula is as follows:

[0064]

[0065] Among them, the D(t) function is used to judge the repeatability of the data sent by the two channels. If they are not repeated, all the data of the two signals are received and processed. If the data is repeated, it enters the time sequence comparison process. The T(t) function is used to compare t1 and t2 to judge whether they are in the same time window, and enters the data fusion process according to the judgment result of the time sequence judgment. The S(t) function is used to fuse the data Dt1 and Dt2 of the two channels to form the final valid data.

[0066] Subsequently, the launch controller sends the interference resource emission information command automatically calculated by the comprehensive decision-making to all emitters through the intelligent bus cable. After receiving the emission information command, each emitter combines its own working state, the situation of loaded interference resources and reserved resources, and according to the types of interference resources, emission quantities, and emission interval requirements specified in the emission information command, sequentially guides the tube positions of the emitter to output high-level signals with a certain pulse width in sequence for ignition and launch, stimulates the interference resources on the tube positions for launch, implements passive interference, and refreshes the status of all interference resources in real time, reporting the launch status, launch results, remaining ammunition quantity, and emitter status to the launch controller.

[0067] Compared with the traditional emitter, the emitter has a newly added intelligent launch module inside. In addition to being compatible with the traditional ignition and launch function, it also has the functions of intelligent identification and data binding for different interference resources. The newly added intelligent launch module, based on the two-wire communication bus technology, can communicate with the internal controller of the new interference resource without changing the form of the traditional ignition contact interface on the emitter. Through this design of the present invention, the interference resource can automatically report information such as the type of interference resource, status information, and combat parameters to the emitter, and the emitter also has the function of data binding, and can load commands such as combat parameters and working status to the interference resource. The emitter solves the problem that different interference resources cannot be mixed and loaded in the traditional emitter, and at the same time enables the emitter to have the ability of co-mounted launch of interference resources.

[0068] The launch controller integrates the functions of the traditional display control box (control box) and the sequencer.

[0069] The emitter expands the functions of the traditional emitter, adds the functions of intelligent identification and data binding, and different types of interference devices can be launched on the emitter.

[0070] The launch controller is interconnected and controlled with the emitter through the bus, and the number of intelligent emitters can be freely configured.

[0071] The intelligent bus can transmit the working power supply of the emitter and the CAN communication bus signal.

[0072] In summary, the above are only the preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
