[0002] With the rapid development of modern military equipment, armored vehicles, as one of the important military equipment, their reliability and maintenance efficiency are crucial to ensure the success of military operations. In the traditional armored vehicle maintenance and fault diagnosis process, there are some problems that need to be solved, which are mainly reflected in the following aspects:

[0003] Large size: Traditional fault diagnosis equipment is usually large and difficult to carry and move, which limits its ability to quickly detect and diagnose on site and is not conducive to rapid response and handling of battlefield emergencies.

[0004] Strong specialization: Many diagnostic equipment are designed for specific chassis or systems, lack versatility, and cannot be widely applied to various types of armored vehicles. This specialization limits the scope of use of the equipment and increases the complexity and cost of logistics support.

[0005] Complex operation: The operation interface of traditional diagnostic equipment is not user-friendly and usually requires professional knowledge and skills to correctly operate and interpret the diagnostic results. This not only increases the training cost of operators, but also increases the risk of operating errors.

[0006] Slow detection speed: The traditional diagnostic process takes a long time and cannot provide fast and accurate fault information in a timely manner, which directly affects maintenance efficiency and vehicle availability and may cause task delays.

[0007] Limited information: Traditional diagnostic equipment can usually only provide limited fault information, lacking detailed fault descriptions and solutions. This increases the reliance on maintenance personnel's experience and skills, limiting the accuracy and efficiency of fault diagnosis.

[0008] Difficulty in updating and maintaining: With the continuous development of technology, it has become difficult to update and maintain equipment, and it is impossible to adapt to new equipment and fault types in a timely manner. This has caused the existing equipment to gradually fall behind and fail to meet the needs of modern armored vehicle maintenance.

[0009] High cost: Traditional diagnostic equipment is often expensive to purchase, maintain, and train, which limits its widespread application and popularity and increases the burden on military budgets.

[0010] In view of the above problems, the existing technology urgently needs a new type of armored vehicle fault alarm panel, which should have the characteristics of miniaturization, strong versatility, easy operation, fast detection, rich information, easy updating and maintenance, and high cost-effectiveness.

[0036] Beneficial effects:

[0037] 1. The size and resolution of the LCD screen can be optimized to clearly display rich and accurate fault information and fault solutions.

The LCD display area is located in the middle, and its position conforms to the ergonomic observation angle. The key area is located at the top, and its layout fully considers the natural range of movement of the operator's hand. When the vehicle fails, the operator's eyes can naturally obtain detailed information from the LCD display area in the middle, and then perform corresponding operations in the switch operation area below. The whole process is smooth and natural, reducing the operation time and error rate. It avoids the problem that although traditional products have clear divisions of areas, the operation process is not simple and efficient for users with different operating proficiency, especially for first-time users, who may need to spend more time to understand and familiarize themselves with the functions of each button.

[0039] Moreover, the metal shell can provide a good shielding effect, isolating the internal circuits and components from external electromagnetic interference. The grounding sheet on the outside of the metal shell can help eliminate the influence of electromagnetic interference in the structure and improve electromagnetic compatibility. At the same time, the multi-cavity design is adopted, so that the main control board is located in the electromagnetic shielding cavity to form electromagnetic isolation, which can reduce the electromagnetic interference to the main control board and ensure the working stability of the alarm panel.

[0040] 3. The main control board of the electromagnetic shielding cavity is connected to the power circuit of the lower sealed cavity through a circuit composed of components including through-hole capacitors and filters, so as to form electromagnetic isolation between the electromagnetic shielding cavity and the lower sealed cavity, thereby further improving the working stability of the alarm panel.

[0041] 4. A second metal partition and a metal adapter plate are provided between the electromagnetic shielding cavity and the upper sealed cavity; the second metal partition and the metal adapter plate separate the electromagnetic shielding cavity from the upper sealed cavity; a through-hole capacitor is also provided on the metal adapter plate, and the main control board in the electromagnetic shielding cavity is connected to the button drive circuit board and the buzzer circuit board in the upper sealed cavity through the through-hole capacitor on the metal adapter plate. In this way, electromagnetic isolation is formed between the electromagnetic shielding and the upper sealed cavity and the lower sealed cavity, further improving the working stability of the alarm panel.

[0042] 5. An insulating plate is provided at the bottom of the lower sealed cavity to ensure that the metal casing will not be charged when leakage occurs between the power supply circuit in the lower sealed cavity and the load control electrical appliance of the armored vehicle, thus ensuring safety.

[0043] 6. A piece of screen shielding glass is set on the surface of the LCD screen, and a conductive rubber strip is set at the connection between the screen shielding glass and the metal shell. In this way, the design of the screen shielding glass can effectively reduce the influence of interference and noise, and improve the picture quality and display effect. At the same time, installing a conductive rubber strip on the contact surface of the screen shielding glass and the metal shell can achieve better electrical contact and grounding, reduce the risk of static electricity accumulation on the fuselage, and enhance the durability of the whole machine.

[0044] 7. Electromagnetic shielding nets are arranged on both sides of the main control board, and the electromagnetic shielding nets are connected to the metal shell to improve the electromagnetic compatibility of the main control board. BRIEF DESCRIPTION OF THE DRAWINGS
