Description

Technical Field

[0002] Aviation weapons and other payloads are usually carried on the exterior and interior of an aircraft through launch racks, and the launch racks need to have the functions of carrying, activating, and releasing weapons.

[0003] The bomb rack hook is the main force-bearing and end-stage component for releasing within the launch rack. The bomb rack hook consists of mechanical components and an electrical control box, and is interconnected with the on-board operating system through a launch rack cable. When the steps of the on-board operating system are completed, functions such as opening the hook can be achieved. Therefore, whether the internal performance of the bomb rack hook is reliable directly affects the success of the release of external stores. Existing detection methods can only detect the operating system, and judge the quality of the bomb rack hook by testing the quality of the system.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figure 1 shown in the structure, this embodiment provides an electrical detector for a bomb rack hook. The electrical detector for a bomb rack hook includes a box body, a control panel 2, a power supply module, a main control module, a touch screen 3, and a delay relay module;

[0028] The control panel 2, the power supply module, the main control module, and the delay relay module are installed inside the box body. A power supply interface 1 electrically connected to the power supply module is provided on one side of the box body. It is connected to 220V alternating current through the power supply interface 1, and then the voltage is converted through the internal power supply module to provide electrical energy for the entire electrical detector for a bomb rack hook; As Figure 1 shown, the electrical detector for a bomb rack hook may further include a box cover rotatably installed on the top of the box body, so that when not in use, the box cover can be rotated and buckled with the box body to protect the control panel 2, the power supply module, the main control module, the touch screen 3, and the delay relay module from accidental bump damage; At the same time, in order to facilitate taking and placing, a handle is installed on the side of the box body;

[0029] The control panel 2 is provided with a touch screen 3, 9 control buttons, and a test interface 4 for detecting the bomb rack hook; The test interface 4 is connected to the electrical interface 5 of the bomb rack hook through a cable. By connecting the test interface 4 to the electrical interface 5 of the bomb rack hook, the output signal of the bomb rack hook is received to achieve the function of detecting the bomb rack hook; The 9 control buttons may include 7 switches and 2 keys. The two keys are respectively located in the upper left corner and the upper right corner of the control panel 2. One of the control buttons KEY1 is connected to the connection circuit between the power supply module and the main control module and the touch screen 3, that is, the key in the upper left corner is used to control the power on and off of the electrical detector for a bomb rack hook; The key in the upper right corner, that is, the control button KEY9, is used to control the input of 5V voltage to the delay relay module; The 9 control buttons are respectively KEY1-KEY9. The power on and other controls are performed through the 9 control buttons, and the human-machine interaction simulation operation system is performed through the 9 control buttons in cooperation with the touch screen 3; The touch screen 3 uses a capacitive touch screen 3;

[0030] The main control module is signal-connected to the touch screen 3 and the test interface 4; The main control module is composed of an embedded single-chip microcomputer, as Figure 2As shown, the single-chip microcomputer can be an Arduino single-chip microcomputer. The single-chip microcomputer is connected to the touch screen 3 through the TX interface and the RX interface to achieve serial communication. The TX interface and the RX interface are respectively set with interfaces 2-10. Among them, interfaces 2-9 are defined as input interfaces and are at high level, and interface 10 is an output interface; among interfaces 2-9, interface 4 is connected to the in-position line inside the bomb rack to detect whether the external load is suspended. When the input of interface 4 is 0, it is displayed normally, otherwise it is not displayed. Interface 2 corresponds to the control button KEY2 on the control panel 2, interface 3 corresponds to the control button KEY3 on the control panel 2, interface 5 corresponds to the control button KEY4 on the control panel 2, interface 6 corresponds to the control button KEY5 on the control panel 2, interface 7 respectively corresponds to the control button KEY6 on the control panel 2, interface 8 corresponds to the control button KEY7 on the control panel 2, and interface 9 corresponds to the control button KEY8 on the control panel 2. When the corresponding control button is turned on and the touch screen 3 is operated, the corresponding interface conversion and display are realized through the internal code, achieving the effect of simulating the operating system. Interface 10 is an output interface. Through the simulated operating system, a 5V voltage is finally input to the delay relay module to realize a high-power output for 2s to the bomb rack electrical control box to realize the detection of the internal delivery line; the input of a 5V voltage to the delay relay module is controlled by the control button KEY9 to realize a high-power output for 2s to the bomb rack electrical control box to realize the detection of the internal discard line;

[0031] As Figure 2 shown, the delay relay module is connected between the power supply module and the test interface 4 and is signal-connected to the main control module; the delay relay module is a DC-DC delay relay;

[0032] Two power supply modules can be set. The power supply module uses a 220V AC to DC power supply to provide DC power for the bomb rack detection and the internal modules of the detector. One of the power supply modules is used to provide a 5V voltage supply for the single-chip microcomputer and the touch screen 3, and the power-on and power-off of the instrument are controlled by one of the switches KEY1. The other power supply module is used to supply power for the detection of the internal circuit of the bomb rack, that is, to realize a high-power supply for 2s to the bomb rack electrical control box.

[0033] In the above bomb rack electrical detector, UART serial communication is adopted between the single-chip microcomputer and the touch screen 3; the touch screen 3 displays a visual graphic interface system. The single-chip microcomputer has a program code for simulating the operating system built-in. The signal reception and transmission are realized through the internal I / O interface, and the operating system process is simulated in cooperation with the switches and buttons.

[0034] As Figure 3The following shows the program steps of simulating the system operation through the touch screen 3 and control buttons after the bomb rack electrical detector is powered on. Press the control button KEY1 to power on the detector, and the touch screen 3 displays the main interface. Operate through the touch screen 3 to enter Interface 1, and then operate the control buttons KEY2 and KEY3 to simulate the system startup, that is, enter the simulation operation system; otherwise, it cannot be entered. Next, enter Interface 2. Through the status display on Interface 2, it can be detected whether the internal in-position circuit of the bomb rack is normal. If it is normal, enter Interface 3 for simulation plan implementation, Interface 4 for simulation selection, Interface 5 for simulation loading, and Interface 6 for dropping line detection. First, press the control buttons KEY4 - KEY6 to achieve the interlock condition. Finally, press the control button KEY7 or KEY8 to achieve dropping line detection. If the hook is released, it means the dropping line is normal; otherwise, a fault occurs. Press the control button KEY9 to achieve jettison line detection. If the hook is released, it means the jettison line is normal; otherwise, a fault occurs.

[0035] The above-mentioned bomb rack electrical detector is provided with a test interface 4 for detecting the bomb rack on the control panel 2. The test interface 4 is connected to the electrical interface 5 of the bomb rack through a cable. The bomb rack can be detected at any time in the off-aircraft environment by using the detector, which greatly improves the work efficiency.

[0036] At the same time, the touch screen 3 can display a visual graphic interface system. Cooperating with the switches and buttons on the control panel 2 can simulate the operation system process, enabling personnel to simulate the operation system usage at any time, and can quickly improve the professional ability level of technicians. It solves the problem in the prior art that the full process of the operation system can only be used with existing detection equipment. During normal maintenance, this equipment is rarely used. Newcomers can only deepen their learning of the operation system steps through technical materials, resulting in the inability of some technicians to quickly improve their professional abilities.

[0037] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these changes and modifications.
