    TKD-3188

    Configuration of 2 inch large QVGA color transparent and reflective TFT LCD screen

    The LCD screen, which accounts for about half of the front panel, uses a two-inch color QVGA (320*240 pixels) resolution transparent TFT display. In addition, the text/logo arranged at the bottom of the display screen can be displayed in two lines, and more information can be seen at a time. The screen can be displayed in Chinese characters that meet the national standards of China.

    It has the functions of PDT digital trunking, digital routine/MPT analog trunking and analog routine.

    TKD-3188 is a walkie-talkie designed according to PDT digital trunking standard adopted by the Ministry of Public Security of China. PDT is a digital communication standard for the development of MPT analog trunking system to digital trunking system. This machine has PDT routine communication function and cluster communication function, and can use frequency efficiently. It can also flexibly correspond to the development of communication network. In addition, because this machine has the dual mode of PDT digital trunking and MPT analog trunking, it can make the existing analog communication system do not need to be eliminated all at once, and can smoothly transition to digital communication system, which is a good cost-effective product.

    With ASELP vocoder, the voice is bright and clear.

    The function of a vocoder is to digitally encode analog speech of a radio station or mobile phone. This machine uses ASELP* speech coding algorithm vocoder (analysis synthesis coding). ASELP vocoder can give full play to its effectiveness in military, public security and other special communication devices which need low-rate coding. Digitalization can make voice noisy and clear. Moreover, through internal optimization processing, the unique voice delay of digital walkie-talkie can be limited to a minimum.

    GPS positioning and state sensing

    TKD-3188 has a built-in GPS receiver. The current location information of mobile terminal (local machine) can be detected by GPS satellite, and the location information can be sent to base station by wireless way. Voice communication and data communication can be used together. In the base station, the received location information is displayed on the computer screen in real time, and the host can be determined at a glance.

    In addition, the machine has built-in state sensor, with fall alarm function. When the intercom is in a transverse (inverted) state beyond the pre-set time, the abnormal situation of the host is determined, and the emergency alarm signal can be automatically sent out.

    High quality and durability.

    TKD-3188 is designed with high standard, strong and durable, and can be used in harsh environment. The environmental test meets 11 requirements of MIL-STD810C/D/E/F/G for vibration, shock, rain, temperature and dust. In addition, it meets the international standard IP54/55 for foreign body intrusion protection in dust and waterproofing.

    In order to achieve impact resistance and drop resistance, and to meet the excellent durability and waterproof characteristics of all-weather use, a variety of experiments were carried out at the design stage. Through elaborate detailed design and elaborate production process to meet the harsh use requirements of public security.

    Waterproof experiment

    Two types of batteries are available

    Two kinds of lithium-ion batteries, KNB-55 of 1480 mAh and KNB-57 of 2000 mAh, can be used. The standard KNB-57 lithium batteries are available for long-term use. It can be used for 18 hours when the power saving function is turned on. When the standard battery is installed, the thickness of the unit is not more than 38.5 mm and the weight is not more than 400 grams. The lightweight body design is easy to hold and operate.
