Solar digital wireless FM system design

Solar digital wireless FM system design this solar digital wireless FM system design ACE Combibloc Audio Electronics Co., Ltd. R & D. What is a solar digital wireless FM system? Explanation of this system before, that first talk about the village rang broadcasting system, the village is the use of sound broadcasting systems Wireless FM remote transmitter and FM speaker to receive audio broadcast and background music system. There are city, county, town, village four response broadcasting system, this is based on the distance to the classification, because the city to the village, some hundreds or even thousands of kilometers, while the effective distance wireless FM transmitter is unable to meet the requirements of this distance a. So IP network broadcasting system on stage, that is, solar digital wireless FM system that can be used long-distance optical fiber solved using the Internet to connect the city to the village unit, simply with a single IP network broadcast terminal in each village unit ACE IP-620, the timely transmission of audio signals to the village by the superiority of IP network broadcast unit, and then install a digital wireless FM transmitter AEO-150W unit in each village, covering a radius of up to 1-20 km, Transmitter Audio signal IP network broadcast terminal IP-620 provides. Thus, the city's people can be achieved through the system of the city to broadcast the village, the first time issued directives. Of course, this system can also be equipped with peripheral equipment I plant AEO-980 phone to play a direct telephone pager notification, you can also use AEO-880 out of SMS broadcast SMS broadcast devices, and other important information promptly issued instructions or disaster relief, the first time the important information Send to phone each villager. Solar digital wireless FM system: 1, the system uses the imported single chip, the US digital control coding; stable and reliable, does not appear due to off can not afford to appear (Banyejijiao) phenomenon. This receive Speaker comes with LCD display "Signal Level Meter Display" function, easy installation, measure the signal strength of each installation point. 2, the front-end and front-end signal from the audio source part of the system unit, transmitters, professional antenna, all devices are arranged in the main computer room. Digital source from the main source including a computer sound card output, DVD simulation program source, and other components. Schools can choose to use the actual situation. Configuring a digital tuner for broadcast morning news program, leisure time enrich the lives of tourists. The computer can automatically output multi-channel digital audio. 3, signal transmission and transmission system consists of a transmitter and antenna, intelligent programming FM transmitter, according to the tourist attractions / Campus / Campus / rural / plaza in the room farthest from the host a fret from the computer room is 2 km away, We Optional 50W transmitter, 50W transmitter coverage generally: 2 km radius away about the extent of the field complex environment unpredictable, so matching transmitter power greater than the insurance, to facilitate future expansion in space. Select the transmitter power distance is generally close to the size of the distance, farther away from the transmitter power is greater. Solar digital wireless FM system features 1, the wireless transmission: the air carrier in the form of load FM-SCA radio FM signal to transmit around, realize transmission and automated management control of all signals, without digging overhead wiring. 2, any partition: A unique feature any partition can be any combination of independence and control multiple areas. 3, each individually addressable point: can achieve point to point control, control any grades or speaker of any class of the power switch, and independent switch fully closed or fully open. 4, regular radio: according to broadcast content, hearing need to set the year, month, week, day playlist, automatic timing system for unattended playback. 5. Auto Play: The computer can be a single automatic timing play under the program to achieve unattended, the player points before the system automatically opens the corresponding region of FM Speaker the power to delay automatic shutdown after playback is done. 7, remote speech: wireless microphone can be achieved through long-distance outdoor speech. With wireless remote control system is easy to use. 8, random spots: During playback, the user can always stop the timer playback, random insertion of other programs, after the end of the spots, the system is still in accordance with the Program to continue playing. 9, beautiful sound: FM radio audio range of 30HZ-14KHZ, small distortion, generally 0.6%; and constant pressure in the range of audio broadcasting system 200HZ-12KHZ, distortion of 8%. 10. Remote Speaker: You can customize the remote control to select the terminal classrooms playback channels. 11 software and hardware dual control, all functions can be controlled via broadcast software, not open when broadcast control computer also available offline, pure hardware control. Computer control priority when the computer is not on, the coding control host control. 12, supports a variety of popular audio formats: such as mp3, mpg, dat, wav, mid, avi, etc., can be connected to a media source recording (such as CD, VCD, deck, radio, microphone, etc.). 13, the operation is simple: broadcast control software is powerful, user-friendly interface design, easy to learn. 14, anti-interference ability: FM radio to FM, less susceptible to outside influence radio and FM broadcast compression technology, it can filter out the interference. 15, multi-channel audio output simultaneously: the user can choose to play multiple programs at the same time according to the actual situation of up to six simultaneous audio output. 16, the system capacity is infinite: the number of the receiving device is not limiting in the signal range can be installed at countless receive only speakers. 17, emergency alarm: A unique emergency broadcast region, forced the broadcast function, when the short-circuit signal to the fire center to host will automatically activate the transmitter to open the speaker to play a tough opening alarm signal. 18, spots Recovery: During playback, random spots, commercials end allows the speaker to continue the previous state and then work. 19, remote management, addressing: Cockpit can be any combination of arbitrary remote school, a region, a switch only speaker. Speakers can set their own reception reception frequency, area code (packet number), single number and volume, digital display. Receiving Cabinet Column can close remote control, regulate single frets sound volume, frequency, area code (packet number) and the like. 20, equipment intelligent management control: broadcast control software, coding control computer, stereo modem can be intelligent management of all front-end device power, automatic timer switch, without duty. 21, the remote control receiver speaker coding function uses advanced microcomputer control technology, multiple anti-jamming technology, error-free; can arbitrarily set the frequency, area, volume, and has a digital display, setting the group number and a single number at the same time, the main control room any combination switch region coding control by computer or host, a district, a receive-only speakers switch to achieve points with RF input, line input and microphone input, you can insert a microphone, MP3 and so on. Full hardware structure, control the curing process in the chip, maintenance-free, free from viruses. Solar digital wireless FM system design background with the deepening of economic reform and the people's living standards improve, we have been an unprecedented development of tourism for the country's spiritual civilization by the light add to the color, to promote the building a "harmonious society" process. But in recent years tourism accidents, Beijing Miyun Lantern Festival night in a park no stampede stampede Huayin, Shaanxi, Hebei Laishui wild three Wave Flood emergencies, Wenzhou, "7.28" fire accident, etc. are all creeps up, resulting in travel safety issues itself has become an important topic of tourists and tourism enterprises concerned. To this end, the National Tourism Administration has requested injunctions tourism enterprises to strengthen security facilities from various angles, to ensure the safety of tourists travel in prime time.
