Functions and composition of buoy monitoring system

The marine monitoring buoy system is a technical system integrated with a variety of monitoring technologies. The entire system consists of anchor buoys, water meteorological sensors, underwater multi-parameter water quality probes, data collectors, GPRS wireless transmitter devices and shore station center laboratories.Can be used for long-term monitoring and management of water quality, and can monitor marine meteorological factors and water quality parameters (pH value, conductivity, temperature, nutrients, dissolved oxygen, turbidity, chlorophyll a, etc.); data can be used through GPRS, or mobile phone signals.The system transmits to the base station and can customize monitoring indicators to send to the user's mobile phone according to user needs.

The research and development of Zequan Marine Ecological Buoy Monitoring System is funded by the Shanghai Innovation Fund and the Shanghai Putuo District Science and Technology Giant Project, and is recognized as a Shanghai High-tech Achievement Transformation Project, with multiple independent property rights.

The monitoring method of monitoring floats should be consistent with national standard methods or industry standard methods, with stable performance, reliable work and good controllability.As shown in the following table:

Communication system

Method one:DT80 connects to 3G router

Configure a DDNS service for the 3G router, access the network through the 3G wireless network card, and access the DT80's Web interface interface at any location through the domain name of the DDNS service.

Method 2: DT80 connects to GPRS cat

The GPRS cat will actively connect to the specified port of a certain IP or domain name, and then access the RS 232 port of the DT80 on the client using a virtual port method.
