Problems solved by technology

[0002] At present, GPRS and GSM are commonly used ways to transmit data, both of which belong to wireless transmission technology, and are greatly limited in transmission speed. Therefore, these two technologies can only realize the transmission of some simple parameters of monitoring equipment. For remote real-time The transmission of multimedia information such as monitored images and sounds is basically impossible, and real-time monitoring cannot be realized

Embodiment 1

[0018] Embodiment 1, with reference to attached figure 1 . The monitoring equipment includes a main control module, a 3G module, a data acquisition module and a control module.

[0019] Among them, the data acquisition module is a sampling interface composed of an analog-to-digital A / D conversion sampling circuit. This example uses an A / D conversion chip LTC1418 chip to collect current changes and convert analog signals into digital signals; the main control module is Pxa270 is the smallest system including power supply etc. as the core. The hardware system is transplanted with Linux operating system, which contains 3G module driver and pppd network dial-up program; the 3G module takes ZTE's MC8360 module as the core, including USB interface, switch, power supply, antenna and other parts; the control module is the general purpose of pxa270 A group of relays driven by input and output GPIOs constitute a control switch.

[0020] The remote console is a personal computer PC co...

Abstract

The invention provides a third generation (3G)-based wireless remote monitoring system, which consists of a data acquisition module and a remote console. Monitoring equipment consists of the data acquisition module, a master control module, a control module and a 3G module. The data acquisition module and the control module are connected with the master control module respectively. The master control module is connected with the 3G module. The 3G module is connected with the remote console by the Internet. In the 3G-based wireless remote monitoring system, monitoring is performed by connecting the 3G module into the Internet to perform monitoring by connecting the 3G module into the Internet to ensure the transmission rate and real-time performance of data, provide advantages for the extension of the system, simultaneously ensure that the monitoring can be performed anywhere without the limitations of a data transmission range, and smoothly realize remote monitoring.

Description

technical field [0001] The invention relates to a wireless remote monitoring system, specifically a wireless remote monitoring system connected to the Internet by using a 3G module. Background technique [0002] At present, GPRS and GSM are commonly used ways to transmit data, both of which belong to wireless transmission technology, and are greatly limited in transmission speed. Therefore, these two technologies can only realize the transmission of some simple parameters of monitoring equipment. For remote real-time The transmission of multimedia information such as monitored images and sounds is basically impossible, and real-time monitoring cannot be realized. [0003] Compared with it, 3G, as an emerging wireless communication technology, is undoubtedly a better choice. Compared with the former two technologies, the transmission rate of 3G is faster. Therefore, in the field of monitoring, 3G can completely realize stable, timely, efficient and fast data transmission and...
