Application of MSP430F149 one-chip computer in the target designator design

The target designator is designed based on the MSP430F149 microcontroller to facilitate rapid target identification in military training environments. It can adapt to various tactical requirements, allowing for the display of targets and the execution of bomb simulations according to different firing protocols. The system is essential for addressing the needs of military training effectively. The target designator can reveal targets or simulate bomb detonations using light, fireworks, or sound. It is equipped with various display features, including firing points for tanks, machine guns, and large artillery, and can operate multiple display units simultaneously. The primary functions involve data acquisition, light and firework displays, and GPS-based target location. The design incorporates the microcontroller as the core component, integrating light and firework displays, as well as target location functionalities. Key design considerations include ensuring environmental adaptability, minimizing power consumption for extended operation, and achieving reliable and stable performance for control command execution and communication. The device must also be user-friendly and maintainable, while being economically viable. The target designator primarily serves to display targets through light, fireworks, or sound, and consists of a control chip, wireless communication module, light display module, firework display module, and GPS positioning power module, as illustrated in the accompanying figure. The MSP430F149 microprocessor is central to the design, leveraging its extensive peripheral capabilities to perform various functions. It receives control commands from a main control station via a radio transmission module and translates these into corresponding control signals through its circuitry. The light display module operates independently, supporting various display modes such as timed light reveals and sequential color displays. The firework display module utilizes real-time geographic coordinates and elevation data to simulate detonations, providing feedback to the main control station. The power module supplies the necessary voltage for the target designator's operation. The hardware control core employs 16 high-performance MSP430F149 microcontrollers from Texas Instruments, each responsible for specific control tasks. The MSP430F149 is a flash-based, ultra-low power microcontroller, ideal for battery-operated or handheld applications. It features low power consumption, with an active mode drawing only 200 µA at a 1 MHz clock rate and just 0.1 µA in sleep mode, alongside five energy-saving operational modes. The microcontroller is equipped with a 16-bit RISC CPU, capable of executing most instructions in a single clock cycle, achieving high efficiency at 8 MHz, with performance exceeding that of typical 20 MHz microcontrollers at 32 kHz clock rates.Designing the target designator on the basis of MSP430F149 one-chip computer, in order to meet the army field and set up the goal fast while training, and can be according to the needs of different tactics flexible to reveal the goal and bomb some, etc. according to different shooting rules, the ones that solved the army field and trained needed badly well.

Depending upon need, the target designator reveals the goal or bombs some by way of light, firework, etc. Goal of the all right n properties such as firing points, firing points of the tank of machine gun, big gun position of analog display of each indicating device, there is m one that bombs some display units at the same time.

Task of revealing etc. of mainly finishing data acquisition, execution light revealing and firework of GPS module of the target designator. Design of target designator taking one-chip computer as the core, collect light reveal and firework reveal and target location reveal function apparent to accuse of the device on a integrative one.

The key point designed includes: Guarantee devices designed can meet the needs of environment; Try hard to reduce the power consumption of the one-chip computer system, enable system to run normally for a long time; The software and hardware designed must be able to realize the strong function, run stably and reliably, finish functions such as execution and communication of the control command, etc. accurately; The device must possess operability and maintainability; Consider realizing the economic cost of this device on this basis.

The target designator is used mainly for realizing the display function of the goal, its display form includes light, firework or sonic boom, it is made up by control chip, having wireless module, module, light display module, firework display module and power module of GPS`s positioning of the ad hoc network, etc. , as shown in Fig. 1. The core of the target designator is a MSP430F149 microprocessor, utilize abundant peripheral module and outside chip of the drib that processor has to realize various functions, it receives and comes from the emissive control command of main control station through the module of transmission over radio, turn into the corresponding control signal through the controlling circuit.

Light the intersection of display module and origin control signal stood to accuse of implement many kinds of modal light display modes independently Including, etc. light time interval reveal, it is different color reveal in turn, etc. , The firework display module lights or explodes to reveal through the level signal of level, module real-time geographic coordinate and elevation supplying main control station with each goal of GPS`s positioning.

The power module is offered the target designator required voltage. The partial control core of the hardware of the target designator uses 16 high-performance MSP430F149 one-chip computers of TI Company, use for each partial job of the control indicator. MSP430F149 is Flash type 16 one-chip computers of ultra low power consumption, especially suitable for battery-driven occasions or handheld devices, have the following characteristics: Low power dissipation: At the time of 2.

2V clock rate 1MHz, the active mode is 200 A; It is only 0. 1 A while closing the mode, and have 5 kinds of energy-conserving operating modes; 16 high-efficient location RISC-CPU: At the time of 27 orders, 8MHz clock rate, the cycle time of order is 125ns, most orders are finished in one clock cycle; At the time of 32kHz clock rate, the implement speed when 16 implement speeds of MSP430 one-chip computer are higher than typical 8 one-chip computer 20MHz clock rate; 🔗 External reference
