(already Viewed 1597 times) I. Overview In recent years, China's comprehensive strength continuously improve, and promote the integration and exchange between all parties and the international face of China and the international has become more frequent, the level of foreign language requirements are constantly increasing. National leaders from the Ministry of Education and then to cause the school, the level of foreign language teaching, foreign language skills high degree of attention and concern, the Ministry of Education of the twentieth century to make major decisions included in the college entrance examination listening to scoring. Our science and technology innovation to serve the community for the purpose of the present situation, in order to improve the level of foreign language teaching, to make teaching more convenient and easy, and effective to improve the effectiveness of student learning and interest, give full consideration to its sound quality and overall stability, the use of modern communication technology, computer technology, broadband digital broadcast receiver chip technology to SONY Mitsubishi and Samsung chip microcomputer locked kernel core chip technology as the foundation, development and design to JBT-1098W is the core of the launch host, with JBT-2000C indoor speakers or JBT-009 headset series to receive specialized training for school foreign language listening and hearing exams campus FM hearing tests and training systems. Second, the program designed to host computer, DVD / VCD, decks, microphones and other analog audio broadcasting analog audio through FM radio transmitter for FM audio modulation, amplification and final stage excitation frequency power amplifier output signal is fed via high frequency cable or high-frequency waveguide feed piped to the vertically polarized antenna, the antenna element is converted into electromagnetic waves in the air broadcast signals transmitted wireless transmission. Philips received the receiving terminal can core chips JBT-009 series of language-specific learning machine receives a radio signal to the air carrier's audio signal is demodulated. Metal through its own speakers, the intonation, tone sharp reduction synchronous play out! Third, the system simple diagram Fourth, the system features advantages 1, the most classic of JBT-1098W transmitters, Mitsubishi and Samsung chip microcomputer locked microcontroller core, launching very accurate and stable frequency, strong anti-interference ability. 38MHz-108MHz frequency is adjustable between 5MHz to avoid interference while simultaneously using the same frequency. 2, external sources can be programmed by the transmitter, transmitter inside 9 groups (18 times) 3 modes switch program, according to program launch time, training content or exam content can be entered in advance by the artistic process, the teacher can control the transmission automatic control or weather broadcast by the transmitter. 3, JBT-009 system headset series, the two models are used PHILIPS receiver chip technology-based, respectively, using a super-regenerative and superheterodyne technology combined with precise firing frequency transmitter, so the sound quality the performance is very soft natural timbre, intonation, and people's feelings can reform reproduce lifelike out to students penetrating feeling, so that students can find the pronunciation errors, thereby promptly correct pronunciation. 4, use convenient, either choose the kind of reception mode, the teacher will be able to accurately pronounce eleven classmates ear exclude outside interference, to create a good learning environment, teachers and students are relaxed and happy to learn a foreign language. 5, scalability is very powerful, adding a partition JBT-3630 controller, fret by FM radio reception can be expanded into a campus background music system! Fifth, the configuration list to a 3000 school standard equipment list type No. Name Type Quantity Unit Remarks emitting portion 1 FM Transmitter 1 set vertically polarized antenna 1 Standard 2 Standard 3 sets the standard 4 antenna feeder 20 m Bracket 1 set the standard 5 lightning protection system, one standard audio portion 6 optional digital tuner 1 Taiwan 1 Taiwan optional mixer 7 8 9 Broadcast Microphone odd sound set of standard seat 1 set standard 10 DVD / VCD / MP3 1 station optional 11 mainframe computer software 1 set Optional receiving section 11 language-specific learning a second election 3000 12 language learning machine 3000 special second election sixteen, service Kat Baxter Technology Development Co., Ltd. for the sale of products or systems promise the following services: 1, for all project-related equipment installed in the spare parts during the warranty period, such as quality problems have a responsibility to be ready for free replacement. 2. If, during the warranty period caused by improper use system components, equipment, parts damaged, will give timely replacement, and only pay costs associated. 3, when a problem occurs with the use of the system with other systems, the company will send professionals to the scene in time to solve when appearing with other systems and the system issues. 4, Ji Baxter Technology Development Co., Ltd. 1-4 people will party system free training, if the purchase is a single device to telephone and Internet remote support (1 pre-construction system and product training, so that the system Learn more about .2 products are installed training in the construction process to achieve to conduct an independent system installation and maintenance works carried out at the end of .3 application training, to enable them to master the system software and hardware for use in a variety of application environments) and related consulting users of the system proposed, Kyrgyzstan Baxter Technology Development Co., Ltd. will be fully answer and the best solution.
