Rainfall warning broadcast automatic data platform bwii broadcast warning monitor

Rainfall early warning broadcast network distribution telemeter remote command voice broadcast automatic data platform

1.1 Function Overview

BWII The broadcast early warning monitor is a fully automatic monitoring and early warning equipment developed for safety monitoring in the field of engineering geology , Collect on-site data acquisition and distribution 、 Monitoring and early warning function of regional broadcast early warning , It can carry out multi-channel acquisition of various sensor types , Including voltage 、 electric current 、 Numbers 、 Pulse, etc . Embedded warning algorithm , When the warning conditions are met, the on-site regional broadcast warning can be realized . Support a variety of wireless data transmission , Including regional self built RF 、 long-range GSM/GPRS .

1.2 The basic principle

BWII Type a broadcast monitor consists of a master station and several slave stations （ The standard configuration is one master station and three slaves ）. The master station is integrated with sensor conversion 、 Timing control 、 Power control 、 Memory 、MP3 Audio recording playback 、TTS Speech synthesis circuit 、 radio frequency 、 bluetooth 、 Wireless intercom 、GSM/GPRS And other functional modules , Under the unified coordination of the central processing unit, the sensing data detection is completed according to the early warning logic algorithm 、 Remote sending of monitoring data and interaction 、 Live broadcast warning audio transmission and other work ; The slave station is responsible for monitoring the warning instructions from the master station , Control the early warning equipment to carry out sound and light on-site early warning , The slave station has high current relay output , The alarm device can be extended and connected by the user .

 

Functional characteristics ：

Multichannel 、 Multi type sensing access . Including voltage 、 electric current 、 Numbers 、 Pulse, etc .
Combination of timing acquisition and event driven , It adopts the working mode of high-frequency sensor scanning and timing acquisition, sending and signing in , Save electric energy to a great extent , Improve the efficiency of early warning .
low power consumption , Adopt patented power-saving control technology , Standby current <500nA（ master station , Without pulse signal ）.
An intensive application structure with one master and many slaves , Under the condition of regional intensive application , It can greatly reduce the equipment capital investment .
The warning audio can be modified remotely , Original use of the first generation GSM The network updates the audio file , You can send short messages directly or make remote voice recording to complete audio modification .
Live broadcast , You can call or send text messages through your mobile phone , Realize remote real-time voice live broadcast ; The same wireless frequency can be used around the site to realize regional broadcasting .（ The broadcast function can be used for emergency command 、 Disaster prevention and mitigation publicity and training 、 message 、 Personnel counseling, etc ）.
Rich wireless network support , Including regional self built RF 、 long-range GSM/GPRS And Beidou message data transmission based on satellite communication .
The equipment has its own lightning protection function , Suitable for outdoor environment .
