Description

Technical Field

[0001] This application relates to the field of ignition detection technology, and more specifically, to an electronic ignition pulse signal detection device. Background Technology

[0002] During production acceptance and subsequent use, rocket launchers must undergo comprehensive functional and performance testing of their electronic ignition pulse function to ensure their reliability and safety. In routine acceptance tests, a detection device is typically used to capture and indicate the electronic pulse signal output from the rocket launcher's directional tube to determine the ignition system's operational status. Because the duration of the electronic ignition pulse is extremely short, traditional detection devices usually use light-emitting diodes (LEDs) as signal indicators: upon receiving the pulse signal, the LED flashes briefly and then immediately turns off, thus visually informing the operator whether a pulse has occurred.

[0003] However, with the widespread application of multiple rocket launcher systems, pulse detection using a single directional tube can no longer meet the requirements for rapid and efficient acceptance and maintenance. When multiple directional tubes trigger electronic ignition pulses simultaneously, the flashing of LED indicator lights often occurs at the same time or within a very short time interval, making it difficult for operators to accurately distinguish which directional tube or tubes are emitting the pulse signal with the naked eye. This not only increases the risk of misjudgment but also prolongs the detection time, affecting the overall maintenance efficiency of the rocket launcher. Utility Model Content

[0004] The purpose of this application is to provide an electronic ignition pulse signal detection device to address the shortcomings of the above-mentioned technology.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0008] The encoding unit is used to assign a number to the detection module corresponding to the position of the directional tube.

[0009] The control unit is electrically connected to the contact unit and the encoding unit respectively. When the pulse signal of the electronic igniter is acquired by the contact unit, the control unit reads the number and generates the corresponding trigger command.

The light-emitting diode provides a visual indication after receiving a trigger command, and the voice prompter provides an audible indication after receiving a trigger command.

[0011] Furthermore, each detection module also includes a power supply unit, which is electrically connected to the control unit and the indicator unit to provide power to the control unit and the indicator unit.

[0012] Furthermore, the encoding unit is a DIP switch.

[0014] Furthermore, each detection module also includes a clamping unit, which includes a handle connected to the positive contact and an elastic element located between the handle and the positive contact. The handle is driven to move the positive contact away from the negative contact so as to place the pulse output terminal of the electronic igniter between the positive and negative contacts. The elastic element has a tendency to move the positive contact closer to the negative contact to clamp the pulse output terminal of the electronic igniter.

[0015] Furthermore, each detection module also includes a housing with a receiving groove, with the negative contact and the positive contact installed opposite each other and spaced apart on the inner wall of the receiving groove, and the pulse output terminal of the electronic igniter passing through the slot of the receiving groove and placed between the positive contact and the negative contact.

[0016] Furthermore, a guide hole is provided on the housing, through which the handle moves to connect with the positive contact.

[0017] Furthermore, the positive contact is provided with a first groove corresponding to the first protrusion of the positive terminal of the electronic igniter pulse output terminal.

[0018] Furthermore, the negative contact is provided with a second protrusion corresponding to the second groove of the negative terminal of the electronic igniter pulse output end.

[0019] Furthermore, each detection module also includes a data storage unit, which is electrically connected to the control unit and is used to record the detection data corresponding to the pulse signal when the control unit acquires the pulse signal.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use.

[0030] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] The technical solution of this application will be described in detail below with reference to specific embodiments.

[0033] This application provides an electronic ignition pulse signal detection device, designed to synchronously, accurately, visually, and audibly detect the electronic ignition status of the directional tubes of a multi-barrel rocket launcher. The device consists of several detection modules, each independently corresponding to one directional tube of the rocket launcher, enabling parallel detection of multiple tubes. Each detection module is directly electrically connected to the pulse output terminal of an external electronic igniter via a contact unit. An encoding unit assigns a unique identifier to each module, a control unit completes pulse acquisition and number matching, and an indication unit provides feedback to the operator via a combination of light and sound, achieving rapid acquisition, accurate differentiation, and user-friendly prompts for multiple pulse signals.

[0034] Specifically, each detection module first establishes a physical electrical connection with the pulse output terminal of the electronic igniter through a contact unit, instantly acquiring extremely short pulse signals. For example... Figure 1 and Figure 2 As shown, the contact unit consists of a pair of positive contacts 8 and negative contacts 6, which are firmly connected to the positive and negative terminals of the pulse output terminal, respectively, to ensure that they can still make firm contact and not slip off under high vibration and shock environments.

[0035] The encoding unit employs a programmable digital encoding device, pre-assigning a unique number to each detection module, corresponding one-to-one with the position of the monitored directional tube. This number plays a crucial role in subsequent data acquisition, processing, and indication: after the control unit reads this number, it can not only correctly distinguish between various input signals in the relay control logic, but also drive the indication unit to emit specific visual or auditory information associated with that number, achieving pipe isolation and clear differentiation during parallel detection of multiple modules.

[0036] The control unit, acting as the "brain" of each detection module, is responsible for amplifying, shaping, and judging the extremely short pulse signals acquired by the contact unit, and simultaneously reading the number of the encoding unit. It then generates corresponding trigger commands through an internally preset trigger mapping table. This process relies on high-speed analog-to-digital conversion and digital signal processing technology, enabling pulse capture and number matching within microseconds. This ensures accurate locking of the trigger time and corresponding number for each channel, even when multiple directional tubes are triggered simultaneously.

[0037] The indicator unit, comprising an LED 3 and a voice prompt 4, serves as the final output for human-computer interaction. Upon receiving a trigger command, the LED 3 emits light and remains illuminated for a delay, providing a persistent and clear visual identifier, thus avoiding visual confusion and misjudgment caused by the momentary flickering of traditional LEDs. The voice prompt 4 (e.g., a speaker) can broadcast pre-recorded or synthesized voice prompts such as "Tube X has been ignited," providing intuitive auditory feedback to the operator. This allows the operator to quickly locate the triggered directional tube number simply by listening to the announcements from different detection modules, even when visual observation is insufficient to capture the light emitted by all LEDs 3. This dual indicator method not only improves detection efficiency but also adapts to complex scenarios with low light levels or limited human vision.

[0038] In summary, through the organic integration of the aforementioned components, this device achieves parallel detection, reliable identification, and user-friendly prompts for multiple electronic ignition pulses in practical applications, significantly reducing the false alarm rate and shortening maintenance time. The overall solution balances high reliability, high precision, high efficiency, and ease of operation, meeting the stringent requirements for functional performance testing of rocket artillery electronic ignition systems.

[0039] Furthermore, the light-emitting diode 3 in this application can be a programmable multi-color light-emitting diode 3 (RGB LED). Specifically, the encoding unit assigns a unique digital identifier to each detection module, which corresponds to a specific color value within the control unit. When the control unit captures the electronic ignition pulse and generates a trigger command, it immediately reads the corresponding RGB color scheme from the internal color map table according to the module's number and sends out a corresponding drive signal, causing the RGB LED on the module to quickly switch to the predetermined red, green, blue, or mixed color light. By integrating encoding, logic, and optical indication into the same closed-loop process, a high degree of consistency and real-time performance between signal acquisition and visual prompts is achieved.

[0040] This multi-color luminous indicator technology has brought significant performance improvements in practical applications. Firstly, in complex environments where multiple circuits are triggered almost simultaneously, operators can simply scan the modules to intuitively identify which circuit(s) has ignited based on color differences, eliminating blind spots that are difficult to distinguish with traditional single-color flashing. Secondly, continuous and stable light output further enhances visibility under low temperature, strong vibration, or dim lighting conditions, avoiding the possibility of misjudgment and repeated detection, and providing reliable visual evidence for subsequent fault location and data recording.

[0041] Furthermore, when performing parallel electronic ignition pulse detection on multiple rocket launchers, the instantaneous flashing indication of traditional LEDs under pulse signals makes it difficult to distinguish the source of each signal when multiple signals are triggered almost simultaneously. To completely solve this technical bottleneck, this device is equipped with an independent power supply unit in each detection module to ensure power stability when acquiring extremely short pulse signals and driving the indicator unit. This power supply unit typically adopts a detachable lithium-ion battery pack design, integrating charge and discharge management, overcharge protection, over-discharge protection, and short-circuit protection circuits. It is tightly electrically connected to the control unit through spring-loaded contacts or a snap-fit ​​structure, providing continuous and sufficient current and voltage support for high-speed signal acquisition and subsequent indication feedback.

[0042] In practical implementation, when one or more directional tubes release electronic ignition pulses almost simultaneously, the contact units of each detection module quickly send the pulse electrical signal to the control unit. After reading the corresponding coded unit number, the control unit immediately issues a trigger command to the indicator unit. At this time, the power supply unit provides sufficient current to the multi-color LED 3, enabling it to light up quickly after receiving the trigger command and maintain a high brightness state for hundreds of milliseconds to several seconds according to the preset delay extinguishing parameters, far exceeding the level of traditional flashing. At the same time, the voice prompt 4 is also powered by the same power supply unit, broadcasting voice information such as "Tube X has been ignited" or "Tube X has been triggered" in real time, thus forming a dual and continuous prompt from both visual and auditory perspectives.

[0043] This device not only completely eliminates the blind spots caused by the instantaneous flickering of traditional LEDs, but also significantly improves the accuracy and efficiency of multi-LED parallel detection through clear and continuous visual and voice prompts. Operators no longer need to stare intently at every faint flash; instead, they can immediately and accurately determine the ignition status of each directional LED through different colored bright lights and corresponding voice prompts. Therefore, in practical applications, this device significantly shortens maintenance and acceptance time, reduces the risk of misjudgment, and provides reliable operational basis and technical support for subsequent data recording and fault tracing.

[0044] Furthermore, the coding unit adopts a multi-bit DIP switch, organically combining mechanical pipe numbering with electronic reading functionality. Each detection module's DIP switch is installed in an easily accessible location on the module panel; a simple press switches the "ON / OFF" state of each switch, thus assigning the module a binary code that corresponds one-to-one with the position of the rocket launcher's directional tube.

[0045] Specifically, the pins of the DIP switches are directly soldered to the circuit board inside the detection module and connected to the general-purpose input / output ports of the control unit. Before system power-on or each test, the control unit sequentially reads the state of each DIP switch through an internal scanning program, converts the binary combination into the corresponding pipe number, and uses this number to drive the multi-color LED 3 and the voice prompt 4 when the trigger pulse arrives. Due to the stable and reliable mechanical structure and electrical characteristics of the DIP switches, their switch life and contact resistance meet high reliability requirements even during frequent operation or maintenance. Furthermore, by using DIP switches as encoding units, this device can quickly and intuitively set pipe numbers for multi-channel detection modules without relying on additional tools or software configuration, ensuring ease of operation and accuracy of system identification.

[0046] Furthermore, each detection module also includes a data storage unit electrically connected to the control unit. Upon acquiring the electronic ignition pulse signal, the control unit immediately drives the indicator unit to provide visual and audible feedback, and simultaneously writes key information from the detection into the data storage unit. In this way, each microsecond-level pulse signal acquired from the contact point, along with parameters such as the module number, system timestamp at acquisition time, signal amplitude, and power supply voltage, forms a complete detection record. This provides traceable digital evidence for each electronic ignition pulse detection and detailed data support for subsequent fault diagnosis, quality assessment, and maintenance decisions. By statistically analyzing and comparing multiple detection records, technicians can quickly identify recurring fault patterns in abnormal pipelines and adjust maintenance strategies in a timely manner, thereby improving the transparency and reliability of the entire rocket launcher electronic ignition detection process.

[0047] Furthermore, such as Figure 1 and Figure 2 As shown, each detection module is equipped with a housing 10 for protecting and supporting the core components. The housing 10 has an outward-facing receiving groove. This receiving groove is used to accommodate the pulse output terminal of the electronic igniter. Positive contacts 8 and negative contacts 6 are respectively arranged on the inner walls on opposite sides. The positive contacts 8 and negative contacts 6 are kept at a certain distance. The pulse output terminal of the electronic igniter can be inserted through the opening of the receiving groove and precisely positioned between the two contacts, laying the physical foundation for subsequent clamping and signal acquisition.

[0048] To achieve rapid and reliable clamping of the pulse output terminal, each detection module also integrates a clamping unit. The clamping unit includes a handle 1 mechanically connected to the positive contact 8, and an elastic element 9 (such as a compression spring) located between the handle 1 and the positive contact 8. A guide hole is provided on the side of the housing 10 to accurately guide the movement of the handle 1. The guide hole structurally penetrates the side wall of the housing 10 in a vertical direction, and its inner diameter is designed to be slightly smaller than the free outer diameter of the compression spring, thereby forming a stable axial limit when the compression spring is in a compressed state.

[0049] The negative contact 6 is securely mounted in a predetermined position on the inner wall of the housing 10 via a retainer 5. One end of the retainer 5 is nested or pressed into a limiting groove or mounting hole on the inner wall of the housing 10, and the other end is connected to the negative contact 6 via a screw, rivet, or clip to prevent the negative contact 6 from shifting, shaking, or tilting. The connecting shaft 2 of the handle 1 is inserted from the outside of the guide hole, passes through the guide hole and the compression spring in sequence, and is finally securely connected to the positive contact 8. Thus, the operating end of the handle 1 is located on one side of the guide hole, allowing the operator to manually grip and pull; while its connecting end is located on the other side of the hole, directly driving the positive contact 8 to move axially. The two ends of the compression spring abut against the outer wall of the guide hole and the end of the positive contact 8 opposite to the positive contact 8, respectively, forming an elastic sliding mechanism with an automatic return function.

[0050] In actual operation, the operator pulls down handle 1, causing connecting shaft 2 to move the positive contact 8 towards the guide hole, gradually moving it away from the opposite negative contact 6. At this time, the space between them is temporarily expanded, providing sufficient operational margin for the insertion of the electronic igniter's pulse output terminal. After the pulse output terminal is inserted through the receiving slot on the module housing 10, it precisely falls between the positive and negative contacts, reaching the docking position just before conduction. During this process, the compression spring is simultaneously compressed, undergoing elastic deformation and storing a certain amount of mechanical energy.

[0051] When the user releases handle 1, the compression spring rapidly releases its stored energy without obstruction. The rebound force causes the positive contact 8 to move towards the negative contact 6, thus automatically clamping the pulse output terminal. This clamping method requires no screws, clips, or other locking mechanisms, nor any auxiliary tools; the user can complete the entire docking process with just one hand. This fast and stable clamping structure greatly improves the practicality and operational deployment efficiency of the device, and is especially suitable for frequent inspection, replacement, and maintenance operations in field environments.

[0052] Overall, the spring-loaded clamping structure used in this application has stronger environmental adaptability. Under conditions of long-term vibration, tilted installation, or high-frequency operation, the contact unit and the pulse output terminal maintain stable and continuous physical contact, effectively preventing problems such as loosening, displacement, or poor contact. This ensures the complete transmission of the electronic ignition pulse signal, laying a solid physical foundation for subsequent pulse identification, number reading, and status indication. In summary, this clamping unit is rationally designed, reliable in operation, and convenient to use, making it one of the key structures for improving the performance and user experience of the detection module.

[0053] It should be noted that a cavity for installing electronic components is also provided inside the housing 10. A highly integrated circuit board is fixedly installed within this cavity, integrating a control unit and a power supply unit, thereby achieving centralized control of signal acquisition, recognition, indication drive, and power management. To optimize the user experience and improve human-machine interaction efficiency, the LED 3 and voice prompt 4 in the indication unit are located on the side wall of the housing 10. The LED 3 is clearly visible in multiple directions, allowing operators to quickly obtain status prompts even when working in low-light conditions. The voice prompt 4 can use an integrated encapsulated high-fidelity speaker assembly, exposed on the surface of the housing 10, facilitating direct sound transmission to the surrounding environment, enabling operators to accurately hear the broadcast content.

[0054] Furthermore, to ensure precise alignment, reliable contact, and long-term stable conduction between the detection module and the pulse output terminal of the electronic igniter, the contact end of the positive contact 8 is provided with a first groove for mating with the positive terminal of the electronic igniter's pulse output. The size, angle, and depth of this groove precisely correspond to the first protrusion structure of the electronic igniter's positive terminal, and it is cylindrical, conical, or multifaceted in shape, ensuring natural guidance and accurate positioning during insertion. Through the matching of concave and convex shapes, this structure not only increases the contact area and improves conductivity stability, but also provides good positioning constraints in environments with external interference or vibration, preventing the positive contact surface from shifting or loosening.

[0055] Correspondingly, the negative contact 6 has also undergone structural optimization, with a second protrusion 7 at its contact end. This protrusion is designed to insert into the second groove at the negative terminal of the electronic igniter's pulse output. This protrusion structure is designed according to the recessed shape of the electronic igniter's negative interface, exhibiting a cylindrical, conical, or multifaceted geometric shape, providing excellent insertion guidance and anti-dislodgement capabilities. During insertion and mating, a high contact clamping force is formed between the second protrusion 7 and the second groove of the negative terminal, further enhancing the stability and vibration resistance of the signal contact. Due to the mechanical limiting and self-aligning characteristics of this structure, even with some errors by the operator in battlefield or field environments, correct insertion can be quickly and accurately completed.

[0056] By incorporating concave-convex mating structures corresponding to the output terminals of the electronic igniter in the positive contact 8 and negative contact 6, the assembly efficiency and operational fault tolerance of the device are significantly improved. Furthermore, in terms of electrical performance, a low-contact-resistance, low-interference, and high-reliability signal transmission path is ensured. This simple and effective structural design is a crucial guarantee for achieving rapid installation, stable conduction, and long-term reliable operation of the detection module, making it suitable for high-intensity, high-frequency, multi-channel ignition detection operations.

[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
