System for remotely monitoring and controlling internet of things on basis of GPRS (General Packet Radio Service) network

Abstract

The invention discloses a system for remotely monitoring and controlling an internet of things on the basis of a GPRS (General Packet Radio Service) network, relating to a monitoring system. A center server with coexistence of two modes such as B / S and C / S is adopted for carrying out data conversion with monitoring terminal equipment and a monitoring center client side by a TCP / IP (Transmission Control Protocol / Internet Protocol) mode so as to realize distributed remote monitoring and controlling. In the system, the operation does not need to create a local area network by self, so that the network creating cost is saved and the reliability is high; and the equipment is general and simple, the cost is low, the one-time investment is less, the use cost is low, the installation and maintenance are convenient, and the operation is safe, no limitation can be caused by the terrain, the landform and the environment, and even no pollution can be caused. The system can be widely applicable to streetlamps, railways, gas, running water, power, environment, petroleum and machines and the like. The system has the advantages of high network access speed, advanced technology, safety, reliability, economy, reasonability, energy conservation, simpleness and convenience in maintenance and strong practicability, and conforms to the trend for development of the conservation-minded society.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a remote monitoring and control Internet of Things system based on a GPRS network. Can be applied to street lights, railways, gas, tap water, electricity, environment, petroleum, machinery. Background technique [0002] Since my country's reform and opening up, the national economy has grown rapidly, and "scientific and technological innovation, independent innovation" has become the mainstream of my country's industrial development. my country's industry is gradually developing in the direction of saving, energy saving, emission reduction and low carbon. With the rapid development of modern technology, network and mobile communication have become an inseparable part of people's daily life. The current communication technology means are very selective. You can choose wired communication such as optical fiber, ADSL, X.25, DDN, etc., or wireless communication such as satellite communication...

AI Technical Summary

Problems solved by technology

However, due to the scattered locations of the controlled objects, the use of wired methods has many disadvantages such as long construction period, shortage of frequency resources, high investment costs, and difficult work, so it is not suitable to use

In the wireless mode, satellite communication is only used in some special fields due to the high cost of communication; and spread spectrum communication technology can only be transmitted within the range of sight, and its application is limited; Digital transmission stations using ordinary indirect modulation are prone to problems such as external interference, low communication rate, high bit error rate, small data transmission volume, and small signal coverage, so they are not suitable for use; the use of power carrier has its own limitations. , easy to cause interference and reduction of transmission signals, the frequency of use in some control system designs is gradually reduced
