Monitoring system and method based on 3G (third generation) wireless communication network

Abstract

The invention discloses a monitoring system and method based on a 3G (third generation) wireless communication network and belongs to monitoring equipment. A 3G mobile monitoring terminal is used as a monitoring terminal, the 3G mobile monitoring terminal is provided with a camera, a voice module and a 3G communication module; and a display management terminal comprises a server and a master control machine, the master control machine is provided with a display device, an input device, a speaker and a memory, and the server is provided with a 3G communication module which is connected with the 3G communication module of the 3G mobile monitoring terminal by virtue of the 3G mobile communication network. The monitoring method comprises the following steps that: by dialing a preset number, the 3G mobile monitoring terminal automatically transmits the acquired video and audio signals to the display management terminal through the 3G mobile communication network, the server of the display management terminal receives the signals trough a protocol signed by both parties, displays the signal data on the display device via the master control machine, and realizes monitoring through the display device. In the system and the method, a 3G mobile phone is used as the monitoring terminal, monitoring for a mobile object can be realized, all the disadvantages in the existing wired monitoring can be solved, and freewill monitoring in any place at any time is realized; and the system and the method are safe and efficient in use, steady and reliable in work, and wide in application range.

Description

technical field [0001] The invention belongs to a monitoring device and method, in particular to a monitoring system and method based on a 3G wireless communication network. Background technique [0002] Most of the existing cities in our country have a variety of urban security monitoring systems such as digital cities or skynet projects. Skynet project refers to a video surveillance system for real-time monitoring and information recording of fixed areas by using image acquisition, transmission, control, display and other equipment and control software to meet the needs of urban security prevention and control and urban management. The Skynet project installs video monitoring equipment on traffic arteries, public security checkpoints, public gathering places, hotels, schools, hospitals, and complex public security places, and uses the network to transmit images of all video monitoring points in a certain area to the monitoring center (that is, "sky net"). Network Project"...

AI Technical Summary

Problems solved by technology

The Skynet project has played a huge role in a city's crime prevention and post-case investigation. It is currently one of the most modern and effective means of preventing and combating various crimes. However, the system has the following unavoidable shortcomings: The implementation of the Skynet project requires a huge investment. Taking a small and medium-sized city with a population of 500,000 people as an example, if seamless monitoring is to be realized, about 1,000-1,500 cameras need to be installed, and the total investment needs to be tens of millions of yuan. Other expenses and losses are also huge (such as broken roads, digging trenches, changing routes, etc.), due to reasons such as technology, financial resources, and the original foundation of the city, for now, there is no city in our country that can achieve true seamlessness. Monitoring, generally only realizes the monitoring of main areas, main streets, and densely populated areas

Secondly, at present, the excessive reliance on wired monitoring equipment has led to the complete paralysis of monitoring in emergencies (such as power outages, network transmission cable failures, artificial damage to cameras or untimely replacement, etc.), making monitoring impossible

In addition, the existing monitoring devices are costly and cannot monitor the movement of people or objects at any time, and the monitoring person cannot actively start and shut down the monitoring, resulting in redundant video at the management end
