Multifunctional terminal of emergency communication system

Abstract

The invention relates to a multifunctional terminal of an emergency communication system, which comprises a power supply management module, a TD-LTF transmission module / off-network transmission module, a voice module, a video module, a heart rate / temperature collection module, a GPS collection module, and a display control module, whereinthe TD-LTF transmission module / off-network transmission module can guarantee that the terminal device communicates with the outside both in the environment of network and no network, and thus guarantees contact with rescuers and communication continuity; the voice module guarantees the communication real-timeness; the video module is used for uploading the accident scene condition to amonitor center, so that the monitor center conveniently transmits the order and commands the rescue; the heart rate / temperature collection module is used for collecting the heart rate and temperature of the rescuers and uploading to the monitor center, and the monitor center analyzes the vital sign information and rescues the rescuers in time; the GPS collection module guarantees the contact with the rescuers and the definition of the rescue geographical position; the display control module is used for performing displaying and operation control on other modules.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a multifunctional terminal of an emergency communication system. Background technique [0002] With the development of the industry, the requirements of industry informatization based on the premise of improving efficiency and safe production have posed new challenges to industry-specific wireless network communications, that is, the increasing demand for large data transmission and high bandwidth in industry communications. At the same time, industry wireless Communication requirements are transitioning from "single voice trunking" to "integrated scheduling of voice trunking, broadband data and video applications", and higher requirements are placed on performance indicators such as delay and capacity. Nowadays, in the process of using the trunking communication system for command and dispatch, industry users must not only "hear", but also "see and see clearly". The...

Problems solved by technology

However, the device uses CDMA technology. Because the same carrier frequency is used, many users share a channel. Strong signals have an obvious inhibitory effect on weak signals, resulting in a "far-near" effect, which affects user calls. The user experience such as transmission rate and service delay is not as good as TD-LTE technology, and it cannot communicate in an environment without a network. Moreover, the device is bulky, difficult to operate by hand, and inconvenient to carry by a single person
