Portable emergency communication instruction receiving display terminal

Abstract

The invention belongs to the field of emergency communications, and in particular relates to a portable emergency communication instruction receiving display terminal. The terminal comprises an outer shell in which a diaphragm plate is arranged; a signal receiving processing PCB and a power source PCB are solid connected with two surfaces of the diaphragm plate in a clinging type, and the diaphragm plate is at least made of aluminum alloy convenient for radiating; the outer wall of the outer shell is provided with an antenna switching coaxial connector, a DC power source interface and a key PCB; the outer wall of the outer shell is further provided with a display screen component, the display screen component is respectively connected with the signal receiving processing PCB and the power source PCB to construct electric connection matching in winding displacement. Through the adoption of the terminal disclosed by the invention, the instruction receiving terminal in the emergency communication is independent in core function, extremely high in portability and environment suitability. The single pawn portability is strong, each carrier can form an independent point-to-point signal receiving terminal system by self, the site strain efficiency in the emergency event can be obviously promoted.

Description

technical field [0001] The invention belongs to the field of emergency communication, and in particular relates to a portable emergency communication instruction receiving display terminal. Background technique [0002] Emergency communication refers to the transmission and communication of audio / video signals and data instructions in the event area after emergencies such as civil air defense, disaster relief, and even war. The emergency communication command receiving terminal is the terminal device for the final communication of the command in the emergency communication under the above-mentioned special environment. The traditional multi-band emergency communication instruction receiving terminal is usually integrated in the display terminal of large-scale equipment such as the display screen of the on-site emergency communication vehicle, and does not exist alone. When on-site personnel carry out rescue and other operations in the deep incident area, they can only trave...

Problems solved by technology

However, since the scene of an emergency may be located in a deep mountain or in an area of ​​electromagnetic interference, the short-wave receiving equipment of individual soldiers often causes poor reception or even failure to receive, which seriously affects the work efficiency of on-site personnel

In addition, it relies heavily on the large-scale equipment display terminal on site as the individual communication tool at the forwarding end. Once the large-scale equipment display terminal fails to work due to damage, etc., the relevant personnel as subordinates will completely lose the external communication function, until the personal safety of the corresponding personnel is endangered.

More importantly, due to the complexity of the environment of the emergency treatment site, the power, transportation, energy and other infrastructure at the event site may be damaged. At the same time, there will be many restrictions on the space for equipment placement. In many cases, it is even impossible to realize the above-mentioned large-scale The erection and normal use of equipment are very unfavorable for the rapid development of emergency work such as disaster relief and rescue.
