Description

PTT Radio Terminal for Disaster Safety Communication having Repeating Function}

The present invention relates to a PTT radio terminal for disaster safety communication with a double window function.

Disaster safety communication network refers to a communication network that enables disaster response organizations such as firefighting, police, military, and local governments to operate independently through a unified command and cooperation system by integrating each independently operated wireless communication network into a single network.

So, the disaster safety communication network is the basic wireless communication infrastructure for establishing the national disaster safety command system, and it uses a separate mobile terminal for the disaster safety communication network to enable quick and accurate decision-making and rescue operations at the disaster site. PTT radio terminals for disaster safety communication such as 1 (hereinafter abbreviated as PTT radio terminals) are widely used.

However, in the event of a disaster such as a large fire, related personnel (firefighters, police officers, soldiers, etc.) who are users of the PTT radio terminal perform function selection such as selecting a channel or increasing or decreasing the volume by rotating the rotary knob. Press the push switch located at the top of the knob or press the release button to turn the flash on / off, press the PTT key of the PTT radio terminal to make a call like a walkie-talkie, and press the key to enter the general or mobile phone number you want to call. It makes a call by input and connects to a network to transmit on-site audio or video to the control center.

In addition, on the screen of the PTT radio terminal, the user selects a function such as channel name / volume to change by rotating the rotary knob, whether the PTT key is pressed, information about the input key, or event information such as receiving an emergency text message. Reports the displayed information, recognizes an event such as selecting a changed function, pressing a PTT key, receiving an input key or an emergency text message.

However, when a large disaster occurs, there is no lighting or very weak environment (for example, inside a building where electricity is turned off at night), so you cannot see the screen of the PTT radio terminal, or if you look at the PTT radio terminal screen, there is a high possibility of an accident. Because it is common to see the screen of a PTT radio terminal because it is in the interior of a building where electricity is turned off at night or when driving, it is common for the user to know what the changed function selection is on the rotary knob. It is difficult to know which key is pressed or an event has occurred, which makes the use of the PTT radio terminal very inconvenient.
