Portable emergency communication command receiving display terminal

Abstract

The invention belongs to the field of emergency communication, in particular to a portable emergency communication instruction receiving and displaying terminal. The terminal includes an outer casing, and a diaphragm is arranged in the outer casing; the signal receiving and processing PCB and the power supply PCB are fixedly attached to the two plate surfaces of the diaphragm, and at least the material of the diaphragm is aluminum that is easy to dissipate heat. Alloy material; an antenna conversion coaxial connector, a DC power interface and a button PCB are also arranged on the outer wall of the outer casing; a display screen assembly is also arranged on the outer wall of the outer casing, and the display screen assembly is connected with the signal receiving and processing PCB and the power supply PCB respectively. The flat wire constitutes an electrical connection fit. The terminal can realize the independent core function of the command receiving terminal of emergency communication, and has extremely high portability and environmental adaptability. Its individual soldier is highly portable, and each carrier has its own independent point-to-point signal receiving terminal system, and the on-site response efficiency of critical events can be significantly improved.

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.
