Remote ultra-high-power forest fire prevention call and Emergency Broadcast System Scheme

I. Introduction
With the elimination of barren hills in Yilin and the implementation of comprehensive afforestation, the afforestation industry continues to develop, and the forest area and forestry stock increase year by year. How to Strengthen forest fire prevention and protect the environment is a major task facing the whole country.
1. Forest Fire in Naji Forest Farm, chenbalhu flag, Hulunbeier City, May 17, 2017

At 12 o'clock in May 17, 2017, there was a forest fire in Naji Forest Farm of chenbalhu flag in Hulunbeier City. As of May 21, 2017, the south line of the fire line had 10 kilometers, and the north line had 4 kilometers of fire lines. The forest fire area could reach 8400 hectares.
2. May 2, 2017 great forest fire in North Dahe Forest Farm, bilar river Forestry Bureau, daxingxing district, Inner Mongolia

A forest fire occurred at the North Dahe Forest Farm of The Bila river Forestry Bureau in the da'anling district, Inner Mongolia in May 2. Due to the dry vegetation of the gully pond, the wind power was heavy (4-5 ), the temperature is high (reaching 28.6 ℃), resulting in rapid spread of the fire field. The fireline shows that the length of each line is 7 km, and the fire field area is about 5000 hectares.
3. Forest Fire in mulong Township, Yajiang County, Ganzi prefecture, March 12, 2017
Smoke in the forest of Mu Rong Township, Yajiang County, Ganzi Prefecture
After the forest fire, the mountains have no devience.
At on June 19, March 12, 2017, a forest fire was distributed in the Mu Rong Township, Yajiang County, Ganzi prefecture. After more than 2100 people (including 614 policemen) and four helicopters, it was completely put out at 13 o'clock on the 21st. The fire area is about 100 hectares.
As can be seen from the above examples of forest fires, forest fires are a sudden and destructive natural disaster. Their consequences not only directly endanger the safety of forest resources and people's lives and property, it will also affect the changes of climate, vegetation, environment, and other factors, and even affect the social stability of forest areas and the development of various undertakings in forest areas. It can be said that the devastating consequences of forest fires are very painful.
In order to avoid and reduce the damage caused by forest fires, based on the characteristics and laws of forest fires and the experiences of the emergency broadcast industry over the past decade, specially developed Remote ultra-high-power forest fire command and emergency broadcast system. The system has unique functions and incomparable advantages that traditional broadcast does not possess. It integrates multiple functions such as timed playback, emergency switching, Digital Amplification, and remote sound amplification, it is the only remote ultra-high-power Forest Fire shouting and emergency broadcast system specifically designed for forest fire prevention systems in China. It is the best choice for forest fire emergency broadcast.
Ii. System Design
1. Forest Fire Prevention Office

The Emergency Broadcast Center platform of the Forest Fire Protection Office is composed of digital tuner, professional broadcasting microphone, Audio Mixer MP3/CD player, broadcast station broadcasting control system, RDS digital encoder, high-power FM broadcast transmitter, dipole FM transmitting antenna, GPRS information publishing platform.
The emergency broadcast control system platform allows you to set up scheduled and Automatic Broadcast of emergency broadcast programs, or enable manual emergency broadcast in real time. You can play a single broadcast terminal in any group or partition or in a unified manner. The platform can control the playback terminal. the control signal is sent by the broadcast and Broadcasting Control System Platform. The RDS digital encoder can connect the control signal to the RDS digital code and then modulated to the sub-carrier of the main carrier 57khz, the high-power frequency modulation transmitter is input in hybrid mode with audio multiplexing, and the broadcast and control signals are transmitted to the dual-layer dipolar antenna for transmitting through the feed tube.
The emergency broadcast control system platform can remotely control Digital Amplifiers in the wild. When the system has a broadcast task, the system sends the boot command to the specified field digital power amplifier at intervals. The field digital power amplifier receives and recognizes its own boot command through the comparator, open the terminal and play continuously. When the broadcast task ends, the system will no longer send boot instructions. When the emergency broadcast receiving terminal fails to receive the boot command for itself, it will cut off the circuit power of the audio amplification output part, switch to the automatic standby status.
The anti-DDOS service office can publish text emergency broadcast information (such as weather forecast, fire prevention information, and precautions) through the GPRS information publishing platform, and connect the system to the Internet, the mobile transmitting tower transmits information to the field Digital Power Amplifier installed in the forest area.
2. Forest Receiving Terminal

According to the forest area and forest farm specific circumstances, in the forest around, residential areas, tourist channels, entrances and exits, configure the corresponding number of ST-1000W super power speaker controller and HT-300 cylinder Speaker (recommended every 3 ~ 5 km configured with 1 group ).
ST-1000W Super High-Power speaker controller, can receive forest Defense Office and higher level forest fire department broadcast automatic Forest Fire propaganda broadcast, as well as emergency remote call, can play a daily broadcast propaganda, emergency evacuation and remote command in critical cases. The embedded GSM receiving module can be used to receive text information from the anti-DDOS service and convert and play texts and texts. You can set the playback times and female broadcasts. The device can be expanded to access the outdoor LED display, and the Emergency Broadcast Text information is displayed cyclically on the outdoor LED display.
HT-300 cylinder speaker is the largest single-drive speaker in China, single cylinder output power up to 300 W, peak power up to 1000 W, maximum sound pressure level 141db, with ultra high sensitivity, the sensitivity (1 W/1 m) reaches analytic dB. A single cylinder speaker can deliver a targeted transmission distance of 1-1.5 km and a four-Component Array of up to 2.5-3Km. It fully meets the requirements of forest fire prevention broadcast for long transmission distance, strong penetration, and high speech recognition.
Iii. Features
? Forest fire prevention publicity: You can automatically play the fire propaganda audio Based on the fire prevention needs of the season and the fire department. The broadcast reminds nearby residents and tourists to pay attention to fire prevention.
? Emergency Notification of extreme weather: in the event of extreme weather such as continuous high temperature and strong wind warnings, the system can promptly broadcast security and fire prevention precautions.
? Publicity on fire prevention during the Ching Ming Festival: Before and After the Ching Ming Festival, you can combine preventive inspections and scheduled broadcast propaganda to strengthen the fire safety and emergency awareness of the masses, and effectively conduct forest fire prevention during the Ching Ming Festival, prevent forest fires.
? Monitoring linkage Remote Call: this service can be integrated with the video surveillance system for forest fire prevention to detect behaviors that do not comply with forest fire prevention specifications. spof and remote calls can be used to stop improper behaviors in real time, secure forest production.
? Phone broadcasting control text message broadcasting: you can connect to the upper-level forest fire protection network. In case of emergency, you can directly broadcast by phone, or send text messages. After the terminal texts are converted, the messages are played cyclically.
? Emergency Command in case of fire: Remote emergency evacuation of nearby persons can be performed in case of fire, to maximize the safety of people's lives and property; remote Emergency Command of the fire brigade to extinguish the fire area.
