The handheld terminal device, belonging to the flight pod equipment, has an overall weight of no more than 1 kg. It is operated by fixing it to the pilot's leg. The handheld terminal acquires video and images from the optoelectronic pod and performs manual storage and playback. It can control the optoelectronic pod's camera gimbal and adjust its parameters, among other command controls. The handheld terminal connects to the optoelectronic pod via a communication cable. Pressing the top switch button 162 powers on the device, and the pod switch controls the power supply to the optoelectronic pod. Figure 5As shown, the bottom area of ​​the terminal device body 1 has a charging port that is inserted and connected to the power module 19. The handheld terminal uses a 7-inch high-definition LCD screen 14 with touch operation function. The right side and bottom of the front are equipped with light-touch auxiliary physical buttons 161 for command operation. There is a work indicator light 164 on the top left of the front, and a light sensor 18 on the top right, which can realize the pod start indication and backlight brightness adjustment function. The bottom right is a three-axis joystick 17 with buttons, which can realize the control of the camera gimbal. The top left is a data transmission interface 165, which can connect to a computer to copy data. The handheld terminal device includes a hardware platform and application software.

The core board 11 includes a CPU processor, FPGA, memory, storage, and SPI. The differential module uses a domestically produced HiSilicon Hi3519 processor and communicates with the FPGA via a high-speed data bus. The FPGA acquires video and images via an SPI interface and connects to the display control board 13 via an HDMI video interface to display the video interface on the LCD screen 14. The carrier board 12 includes an MSP430 microcontroller, a power supply assembly, a serial communication module, etc. The microcontroller communicates with the light sensor 18 and the joystick 17 via two I2C interfaces, acquires the physical button status via multiple I / O channels, and performs command operations and acquires status information with the optoelectronic pod via an asynchronous RS422, transmitting the acquired information to the processor on the core board 11 via a serial port. Two USB interfaces are used for control of the touch screen driver board 15 and data export interface, respectively. The system uses the optoelectronic pod for 28V power supply. After EMI filtering, the power input is supplied with 12V and 5V power through a DC / DC module for powering various components. The system block diagram is shown below. Figure 6 As shown, the joystick 17 is a domestically produced industrial-grade small 3-axis Hall effect joystick with button function. It is panel-mounted, made of stainless steel, and features a spring-loaded automatic return mechanism. The main joystick offers ±20 degrees and 360-degree omnidirectional operation, includes waterproof buttons, DC 5V power supply, I2C communication for signal output, an operating temperature range of -40℃ to +70℃, a storage temperature range of -55℃ to +85℃, a high-precision Hall effect sensor with linear correction across the entire temperature range, IP65 protection rating, smooth operation, and ergonomic mechanical design. The auxiliary physical buttons 161 are waterproof tactile buttons soldered onto the PCB. Operation is achieved by activating the button caps. The buttons have a mechanical life of 1 million cycles, good impact and vibration resistance, and the button layout is as follows. Figure 3As shown, the handheld terminal housing is made of aerospace-grade hard aluminum using integrated CNC machining, resulting in a compact and robust structure. Internally, it employs a layered, stacked structure, with the core board 11 and carrier board 12 interlocking for secure mounting. This design balances electromagnetic interference across modules, featuring a rational layout and a large-arc design at the edges. The back is equipped with straps 2 and quick-release buckles 3, secured to the operator's thigh via the quick-release straps 2, which are made of wear-resistant and aging-resistant nylon braided material. The quick-release buckles 3 allow for easy and quick removal. Straps 2 and quick-release buckles 3 are existing technology components and will not be discussed in detail here. The length of straps 2 can be freely adjusted according to the user's body shape. The design prioritizes minimizing product size and utilizes filtering technology for optimized design. Electromagnetic interference is transmitted through conductive or radiative coupling. To meet electrical requirements... For magnetic compatibility requirements, radiation coupling is suppressed using shielding technology, and conducted coupling is suppressed using filtering technology and EMI filtering devices. Specific electromagnetic compatibility measures are as follows: The PCB uses large-area ground planes to remove floating copper, using all unoccupied blank areas on the circuit board as ground planes to bring components closer to the ground line. Special signal routing uses "ground-wrapped" routing to minimize parasitic inductance. Simultaneously, large ground planes effectively reduce noise radiation. The PCB uses 45-degree bends instead of 90-degree bends to reduce high-frequency signal emission coupling. The PCB is zoned according to frequency and cable switch characteristics, with noisy and non-noise components laid out separately. Routing density should be rationally selected based on structural and electrical performance requirements, striving for simple and uniform routing. The minimum wire width and spacing should generally not be less than 0.2mm. When wiring density allows, the printed conductors and their spacing are appropriately widened. A discrete filter is used for power supply, employing a T-type filter circuit composed of ferrite beads and capacitors. Bypass capacitors are connected between the power supply and ground lines to shorten the path of switching current. Impedance matching resistors are connected at the line termination and start to eliminate interference. When the printed conductors are long, the line inductance can cause damped oscillations; adding damping resistors can suppress oscillations and enhance anti-interference capabilities. EMS and EMI hardware circuit designs are implemented for the power board, CPU board, carrier board 12, serial port card, etc. Simultaneously, common-mode interference, differential-mode interference, signal return current, and ground plane distribution factors are fully considered in PCB layout to improve electromagnetic interference immunity. The ground wires are connected to the casing at the clock and crystal oscillator locations. Conductive coating is sprayed inside the handheld terminal casing to ensure the conductivity of the entire casing and meet the product's electromagnetic compatibility requirements. The board and housing are sealed with conductive sealing strips to prevent radiation interference. The screw hole spacing is 20-30mm, and the hole diameter is no greater than 3mm. Conductive silicone is applied to the external fixing screws during installation. Shielded power cables are used, with an external shielding mesh. Shielded connectors are employed. Dedicated military-grade twisted-pair shielded cables with external shielding mesh are used for communication cables. An EMI shielding film is applied to the touchscreen surface to meet the product's electromagnetic compatibility (EMC) requirements. EMI aviation connectors are used, with integrated feedthrough filters. Conductive sealing gaskets are used to suppress radiation interference from the connector screw holes. An EMC information closed-loop system is established, with closed-loop information management requirements and procedures defined. Important EMC information is recorded and provided to the supplier according to EMC requirements.
