Not only improve the skills of the soldiers to use weapons, you can also teach them how to protect themselves in the war. Hangzhou University of Electronic Science and Technology graduate design using a variety of new technologies to increase simulation realism, such as a computer to record and control the process of training exercises, to assess the performance of soldiers in the exercises. The design idea of this design in order to achieve a good signal detection and data conversion, transmission as the main purpose; signal detection, signal encoding and data transmission as the main design. The design of a single pulse signal amplifier circuit in the signal detection and signal shaping circuit; in terms of signal coding, to solve the multi-channel signal encoding, but also consider the preference to coding. The core goal of Laser Pointers will be introduced.
Synchronization (see Chapter II hardware design part) off target approach, targeting and signal acquisition, transmission, off target and the target is classified as a class processing; data transmission using a UART serial communication. R & D direction and key technologies. Rational division of the photodetector of the laser target, to improve the accuracy of the system; single-pulse amplification and shaping of small-signal; the expansion of multi-channel priority encoder; and PCs for data transfers, facilitate the statistics of the results, save, display and query. The main technical indicators of the laser pulse: shooting distance: serial output frame format: greater than 1ms 30 meters Shots + hit number of photoelectric detectors. Laser pulse response amplitude. The supply management of waterproof flashlights has been enhanced.
About 10 mv Hangzhou University of Electronic Science and Technology undergraduate graduation design of the overall design of the laser targeting system is a set of optical power in one system, and its working principle is a laser beam from the laser gun, hit a photoelectric sensor, photoelectric sensor convert optical signals into electrical signals, the signal after signal processing by the microcontroller to the computer's serial port, and then on the computer results show that query and save. The laser targeting system block diagram of the structure shown in Figure 3-1. The system includes a semiconductor laser guns, modular detectors, digital signal processing and transmission circuit, and computer data processing program of four parts. It is finding the better supplier of waterproof flashlights.
Each targeting laser gun emits a laser pulse. If the laser pulse hit the photoelectric target, the use of photovoltaic effect, photoelectric target detector to convert optical signals into electrical signals, so the detection of the laser detector response signal detection. The response of the photodetector is a single pulse signal, the entire testing process including: signal amplification, waveform shaping, the detection output is a standard pulse digital signal. The target for the division of a laser target is divided into 38 detector, center ring 10 to a detector; 9.8.7.6 ring of eight detectors; ring with five detectors. According to different targets on the detector to determine the location of the hit, including the number of rings: 10.9.8.7.6.5. It is developing the competitive supplier of waterproof flashlights for the enterprise.
Deviation from the direction: left. Right. Upper left. Lower left upper right. Bottom right. If the signal hit the junction of two or four detectors, only take one piece, note the following conditions are met: high number of rings for the effective detector; deviation from the direction of the diagonal (for example: on the upper right in two directions, select upper right). Different detectors according to the above requirements, as well as the needs of the hardware circuit design, coding, as shown in Figure 3-2 (right). Figure 3-2 target classification and numbering 3.3 coding standard 38 signals according to the above principle of coding, coding results are shown in Table 3-1. Off target and no signal is recorded as the number of 0. Encoded, each number corresponds to the location information of each detector, including the ring number and the offset direction. The product of waterproof flashlights is in the better quality.
