Problems solved by technology

When using a telephone line to transmit data, the speed is slow and the cost is high because of the need to wait for each dial-up
At the same time, due to the wide distribution, large number and long distance of each monitoring point, some points are still located in remote places, so many telephone lines need to be applied for, and some monitoring points are difficult to reach with wired lines

Abstract

The invention discloses a public network environmental protection data acquisition system based on a GPRS (General Packet Radio Service) network, which is characterized by mainly comprising an environment monitoring system, the GPRS network, the Internet and a data center which are sequentially connected. The public network environmental protection data acquisition system based on the GPRS network has the advantages that: 1. the reliability is high; 2. the real-time performance is strong; 3. the reading range is wide; 4. the construction cost of the system is low; 5. the operating cost of the system is low; and 6. the transmission capacity of the system is large.

Description

technical field [0001] The invention relates to environmental protection data collection, in particular to a public network environmental protection data collection system based on GPRS network. Background technique [0002] As the technical department of the national environmental protection system, the environmental monitoring department is an important basis for environmental management. With the enhancement of citizens' environmental awareness, more and more people are concerned about the quality of their environment and require transparency in environmental protection work; higher-level authorities also need information that is distributed in large quantities, types, and updated quickly. All of this raises a problem that should be paid attention to by the environmental monitoring department: how to establish an environmental protection data collection system with strong practicability, wide coverage and good flexibility to meet the needs of all aspects of environmental ...
