Description
Technical Field

The remote communication monitoring system adopts a GPRS wireless data transmission module (GPRS DTU) which is an internet of things wireless data terminal and provides wireless long-distance data transmission function for users by utilizing a common operator GPRS network. The GPRS DTU wireless data transmission module and the data center carry out data transmission through a TCP/IP protocol, and the data center needs a computer or a server with a public network fixed IP address. The data center is used as a server side monitoring port, and after the data acquisition module is powered on, TCP connection is actively established with the data center, and equipment login is carried out. After the connection is established, the data center generally issues commands to read data or to perform settings. The communication mode has long transmission distance, but can generate data interruption or data transmission error (communication error code ≦ 10-6 ‰), such as mobile network instability, signal interference, GPRS DTU voltage fluctuation and other reasons. In addition, in the process of data transmission, flow charge or short message charge (each GPRS data transmission module needs at least 10 yuan per month of packet per month of flow charge, a server end needs to be provided with a fixed IP broadband line (the Shijiazhu area is communicated with 10MB of bandwidth fixed IP charge is 1800 yuan per month) with high cost or applies for a network domain name, and domain name resolution software (more than 1000 yuan per year of use charge) is used for replacing the fixed IP with high cost, but a link of domain name resolution is increased, and due to the inherent defect of temporary failure of the domain name resolution service, the error rate and the disconnection time are increased when a domain name resolution mode is used.
