Device capable of receiving and sending various alarming messages and conducting acoustic code word communication

Abstract

The invention discloses a device capable of receiving and sending various alarming messages and conducting acoustic code word communication, which comprises a channel modulator / demodulator, a channel coding / decoding module, a data coding / decoding module, an LCD (liquid crystal display) module, a microprocessor control module, a panel operating and displaying interface module, an analog voice / data voice conversion module, a digital alarming signal generator, a transmitter interface and an audio output interface. When a radiofrequency antenna receives an alarm and an alarm message, the channel modulator / demodulator conducts radiofrequency demodulation to the received signal firstly, then the channel coding / decoding module decodes the channel signal, the data coding / decoding module decodes the transmission data, and the LCD module displays the alarm and the alarm message. The device not only can receive alarms or alarming messages, but also can give an alarm or an alarm message, can display the specific content of the alarms or alarming messages by audio or characters, and also can be used for acoustic code communication in need.

Description

technical field [0001] The invention relates to a device capable of receiving and sending various alarms and warning information and performing digital voice communication, in particular to a device capable of giving sound alarms and text prompts for various received alarms and warnings. Background technique [0002] Typical existing equipment includes alarm terminal control equipment and various monitoring and alarm equipment produced by existing manufacturers. The alarm terminal control device is unidirectional. When an alarm or warning message needs to be issued, the equipment monitoring center sends a line signal carrying the alarm or warning message. After receiving the line signal, the alarm terminal control device decodes it and starts the light. or an audible alarm. One of its disadvantages is that the types of sound alarms are limited. At present, the country only defines sound format standards for the three sound alarms used by civil air defense departments: pre-a...

Problems solved by technology

One of its disadvantages is that the types of sound alarms are limited. At present, the country only defines sound format standards for the three sound alarms used by civil air defense departments: pre-air raid warning, air raid warning, and air raid relief warning. For various disaster warnings such as typhoon warnings and tsunami warnings , Flood control alarm, flood discharge alarm, debris flow alarm, fire alarm, earthquake alarm, chemical accidents, etc. cannot be identified through sound discrimination; second, the light alarm mode is single, and it is difficult to distinguish the alarm types

When it is necessary to receive an alarm or warning message, the monitoring and alarm device transmits the message to the equipment monitoring center. The alarm or warning message transmitted in this way is single, and the specific content and nature of the message cannot be distinguished
