Put out the fire
While Firefiters are putting out fire, they also need to protect farmland and livestock from loss and keep the residents safe. It would be a burdensome battle to the firefighters. If they failed, they might lose their lives in the dangerious place. What's worse, the disaster would threaten the lives and property of more people.

What communication tools are people currently using in emergency rescue at present? Compare their communication equipment.Can these tools solve the problem of information exchange in hierarchical management? Firefighters common communication equipments The walkie-talkie is a terminal device for cluster communication. It can be used not only as a terminal device for cluster communication, but also as a professional wireless communication tool in mobile communication.Suitable for communication between mobile personnel in various occasions at close range (no more than 8 kilometers)
Use environment：Various indoor and outdoor dry environments Connection method：radio
US "Army Warrior" Soldier Communication System Nett Warrior is the US Army's next generation US integrated soldier system which is designed to be an integrated dismounted situational awareness and mission command system for use during combat operations that enables fast and accurate decision-making during tactical operations.
Use environment：harsh environments such as temperature extremes, rain, mud, dust, sand and even temporary water immersion Connection method：radio
The main function of satellite phone is to fill the area that cannot be covered by the existing communication (wired communication, wireless communication) terminal. All the communication functions provided by the existing common communication have been applied in satellite communication.
Use environment：Outdoors without building Connection method：satellite
satellite telephone of a certain brand
Intercom of a certain brand

Fix the distance between the mouth and the microphone
FM and volume Microphone and speaker Numeric keypad
too far away:the other party can not hear clearly
At the same time, information can only be transmitted in one direction. This transmitter and receiver can only work alternately, not at the same time. Features:Both parties should take turns to speak, the circuit design is simple, the price is cheap, and the frequency can be fully utilized.
Duplex wireless intercom(Non-mainstream models) Information can be transmitted in two directions at the same time, just like making a phone call. Features:The circuit is complex and it will waste frequency resources, but will b suitable for special occasions
Information transfer speed convenience of operation Portability Economic cost
Advantages
Disadvantages
Rugged housing protects the inside. Does not require communication network support. The two-way radio provides one-toone and one-to-many calls. It is easy to speak with one touch. Low call cost Used between mobile personnel
The communication distance is limited. Need to control the distance between mouth and microphone. Only voice messages can be passed Added parts and not easy to wear
Antenna
After turning on, the phone will have about 20 seconds to search for stars. According to the preset time, send the real-time location of the owner to the contact
Manual
too close: produce noise
Simplex wireless intercom(Mainstream models) classification
Satellite telephone
Nett Warrior
Individual command system
Nett War r ior is based on an “end user device,” essentially an Android or iPhone-like smar tphone tied to the Rifleman handheld radio, to link into command and control networks and use applications to call in fire support, plan and coordinate operations, and track friendly forces.
Telephone equipment based on network digital battlefield command system.
Disadvantages
Adapt to multiple battlefield environments
Information other than voice is more complicated to process
be used for:
see other soldiers’ positions, mark IED and enemy troop positions, text each other.
Speak directly with the commander.
Design requirements:
Design requirements: Wearable and fixed
Differences from ordinary mobile phone operations
Information transfer speed convenience of operation Portability Economic cost
Advantages
be used for:
Suitable for use in wet and dusty environments, can accept the operation of fireproof gloves, and has good readability in sunlight
Advantages
1.Insert satellite sim card 2.Turn on 3.Open the antenna 4.Manually search the Internet 5.Make a call
Disadvantages
Can be used anywhere under Complex operation satellite coverage Slow transmission Send location information regularly
These devices have the following advantages that need to be retained: Rugged housing, Portability, Send location information regularly, Used between mobile personnel, Adapt to the wild environment

The environment is still terrible, just proceed as usual
Relief
Under the level-by-level communication system, there are amounts of different kinds of information transfering during these significant parts. So the smoothness of information communication has a direct impact on emergency rescue.

Information input process
Prevent accidental touch
Comfortable to hold
Easy to wear
When can it be used without holding it? For executor: Report normal signal, Record task completed, Ask for help
Traditional screens are not conducive to operation after wearing gloves. In this case, larger, more obvious and better distinguishable keys are needed, and reduce the need to operate while watching the screen
For hardware:
For commander: Import assignment information
For commander: Communication
Convenient to use with protective gloves
Single finger can achieve basic functions
When do users need to hold for a long time?
For executor: Feedback problem information
Wearing gloves reduces finger sensitivity
Information output process Some functions can be used without holding it
When you are not wearing gloves, you can use the touch screen to perform some more advanced operations, such as viewing and marking maps, etc.
For software: Where should the communicator be worn on the body ？ Spacious operating area
The operation is straightforward and convenient,there should be a key for the lock screen and lock button
