Description

Technical Field

[0001] The utility model relates to the technical field of aircraft jammer emission, in particular to an airborne jammer in-place detection circuit. Background Art

[0002] Fighter planes, helicopters, transport planes and special platform aircraft are generally equipped with jammer delivery equipment. Jammers are mainly used to interfere with enemy radar or infrared guided weapon systems. Jammer dispensers are one of the important means for aircraft to evade enemy radar and infrared guided weapons during use, and they play a vital role in improving aircraft survivability. After executing the jammer delivery program, it is necessary to detect whether the jammer is delivered normally and to make up for it according to the remaining chamber situation, so as to ensure the effectiveness of the delivery program. However, there is currently no method for detecting the jammer delivery results, and the remaining chamber situation cannot be inferred from the jammer delivery results, resulting in the inability to obtain the jammer remaining chamber situation in time, which is not only prone to failure, but also easy to cause the termination of the entire jammer delivery program, and the effectiveness of the delivery program cannot be guaranteed. Utility Model Content

[0003] The utility model provides an airborne jammer in-place detection circuit, which can perform in-place detection on the jammer after the delivery program is executed, and design a jammer supplementary delivery program planning method according to the remaining chamber situation, thereby solving the current technical problem of the lack of timely and accurate detection of jammer delivery results.

[0004] In order to achieve the above technical objectives, the specific technical solutions adopted by this utility model are:

[0005] An on-site detection circuit for an airborne jammer includes an on-site detection power supply and an optocoupler acquisition circuit. The airborne jammer is equivalent to a resistor R. A resistor R1 and a diode are connected in series between the on-site detection power supply and ground. The equivalent resistor R is connected in parallel to the optocoupler acquisition circuit.

[0006] Furthermore, an equivalent resistor R is arranged between the jamming core and the jamming ring, and the equivalent resistor R is arranged in parallel with the optocoupler light emitting diode and the optocoupler current limiting resistor arranged between the jamming core and the jamming ring, and the optocoupler light emitting diode and the optocoupler current limiting resistor are arranged in series between the jamming core and the jamming ring.

[0007] Furthermore, a photocoupler is provided on the photocoupler acquisition circuit, and a photocoupler light emitting diode at the front stage and a photocoupler transistor at the back stage are provided in the photocoupler.

[0008] Furthermore, the optocoupler transistor and the pull-up resistor R3 are connected in series between the optocoupler collection power supply and the ground. The optocoupler collection circuit is provided with an optocoupler post-stage output terminal, which is located between the optocoupler transistor and the pull-up resistor R3.

[0009] Furthermore, the resistor R1 is 510 ohms.

[0010] When the airborne jammer is in place, the jammer's equivalent resistance R is about 1 to 2 ohms. Due to the voltage divider between the resistor R1 and the diode, the voltage of the jammer's equivalent resistance R is much smaller than the conduction voltage of the optocoupler light-emitting diode. At this time, the optocoupler transistor outputs a high level, and the corresponding signal is output through the optocoupler's post-stage output terminal.

[0011] When the airborne jammer is launched, the jammer's equivalent resistance R reaches more than 500 ohms. After the voltage is divided by the resistor R1 (510 ohms) and the diode, the voltage value on the jammer's equivalent resistance R can make the optocoupler light-emitting diode stably turned on. At this time, the optocoupler transistor outputs a low level, and the corresponding signal is output through the optocoupler's post-stage output terminal.

[0012] By identifying the level change of the output terminal of the optocoupler before and after the launch of the airborne jammer, the launch status of the airborne jammer can be determined.

[0013] By adopting the above technical solution, the utility model can also bring the following beneficial effects:

[0014] The utility model provides an on-site detection circuit for an airborne jammer, which can efficiently complete the on-site detection of the jammer and timely complete the supplementary delivery plan to ensure the effectiveness of the delivery plan. At the same time, the supplementary delivery time of the jammer is very short, and the impact on the time period of the entire delivery program is very small. The situation where the jammer cannot be supplemented in time can be avoided at the lowest cost, and the entire decoy can be guaranteed to play a role normally, thereby ultimately protecting the entire aircraft from threats to its survival convenience.

[0022] Additionally, in the following description, specific details are provided to provide a thorough understanding of the examples. However, one skilled in the art will appreciate that the aspects described can be practiced without these specific details.

[0023] Example 1

[0024] In one embodiment of the present invention, see Figure 1The utility model mentions an airborne jammer in-place detection circuit, including an in-place detection power supply and an optocoupler acquisition circuit, the airborne jammer is equivalent to a resistor R, a resistor R1 and a diode are connected in series between the in-place detection power supply and ground, R1 is 510 ohms, and then the equivalent resistor R is connected in parallel to the optocoupler acquisition circuit end; when the airborne jammer is in place, the jammer equivalent resistance R is about 1 to 2 ohms, due to the voltage division of the resistor R1 and the diode, the jammer equivalent resistance R voltage is much smaller than the optocoupler light-emitting diode conduction voltage, at this time the optocoupler outputs a high level; when the airborne jammer is launched, the jammer equivalent resistance R reaches more than 500 ohms, after the voltage division of the resistor R1 and the diode, the voltage value on the jammer equivalent resistance R can make the optocoupler light-emitting diode stably conduct, at this time the optocoupler outputs a low level; by identifying the level change of the optocoupler output end before and after the launch of the airborne jammer, the launch status of the airborne jammer can be judged.

[0025] The onboard jammer in-place detection circuit can timely detect the jammer's chamber status, and can timely replenish the ammunition to ensure the normal implementation of the jammer delivery program.

[0026] The jammer delivery procedure is mainly determined by the system design. Different aircraft have different numbers of dispensers, and may also have sequencers or other equipment. There may be differences in interface design. However, for in-situ detection and supplementary delivery, in order to ensure the effectiveness of the jammer delivery procedure, in-situ detection should be carried out on a dispenser basis. The timing of in-situ detection should be when each dispenser completes the current delivery procedure. The components of the delivery procedure include at least the type of jammer, the number of deliveries, the interval between deliveries, the number of delivery groups, and the group interval. Here, the current delivery program of a single dispenser is defined as the minimum set, that is, one type of jammer completes a group of deliveries. At this time, the in-situ detection circuit detects the presence of the jammer and reports it, and continues to execute the next group of delivery procedures.

[0027] The integrated control and management of all jammer dispensers is completed by the delivery management software residing in the upper-level avionics equipment. The delivery management software completes the delivery program planning and jammer delivery control and management. When a single dispenser detects a retained chamber, it updates the jammer list of this dispenser (including the retained chamber status) and reports it. The delivery management software plans the jammer replenishment program based on the retained chamber status. The whole process is described in detail in the following sections. Figure 2 .

[0028] The planning steps for the jammer re-delivery procedure are as follows:

[0029] A. Taking a single dispenser as a unit, the timing for detecting the presence of jammers should be when each dispenser completes the current delivery procedure.

[0030] B. Based on the reported chamber retention situation, immediate supplementary delivery planning is carried out. The planning factors include the type of jammer, the number of supplementary deliveries required (A0), the bombing interval, and the choice of dispenser.

[0031] C. For the jammer type in the planning scheme element in B, the jammer type detected is the type of jammer remaining in the chamber. If there are multiple types of jammers reported by different dispensers, the scheme planning will be carried out one by one. Here, only one type of planning is used as an example.

[0032] D. The number of additional drops A0 for the planning element in B is the sum of the number of additional drops of this type of jammers reported by all dispensers at that moment;

[0033] E. Set the bombing interval of the planning elements in B according to the bombing interval of the previous jammer release program for this type of bomb;

[0034] F. The selection of the launcher for the planning scheme element in B and the number of bombs dropped by the launcher are calculated based on the launcher priority, the remaining bombs of the launcher and other constraints.

[0035] Follow these methods:

[0036] The priority of the dispenser selection is based on the following table:

[0037]

[0038] Based on the principle of minimal design, there are three planning results for the replenishment plan of a single dispenser:

[0039] The remaining ammunition is insufficient and cannot be replenished;

[0040] If the remaining ammunition is insufficient, a non-delivery plan is generated and some ammunition is delivered;

[0041] The remaining ammunition meets the requirements, a replenishment plan is generated, and the replenishment is successful.

[0042] The replenishment plan is planned based on the type of replenishment jamming bombs, the required replenishment quantity, the current comprehensive list of jamming bombs and the preset residual bomb quantity (the preset residual bomb quantity is 0 in manual mode), and the dispenser used for replenishment and the required release of the dispenser are obtained, thereby ensuring the normal progress of the entire jamming program and protecting the aircraft from survival threats.

[0043] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
