Abstract

The present invention discloses a data collection processing system based on a 3G network and a method. The system comprises a control host machine, the data signal of the RS-232 or RS-485 interface of an industrial control field, a switch quantity signal and an analog quantity signal. The signals are connected to a data collection processing device through signal lines. The data collection processing device is internally provided with a 3G network card which is connected to the control host machine. The method comprises a control host machine query step and a data collection processing device independent query step, and the transmission of a query result to the control host machine by using the 3G network. According to the system and the method, the sending of a query command all the time by a host machine is not needed, which means that the change of equipment is grasped in real time, and while software workload and data flow are saved greatly, the control of an equipment state is not lost.

Description

technical field [0001] The invention relates to data collection, and is a data collection and processing system and method based on a 3G network. Background technique [0002] In the field of industrial control, we often encounter the problem of collecting and processing field data. These data include some RS-232 or RS-485 interface data information, as well as switching and analog information output by various sensors. , Sometimes users also need to control on-site switching and analog input devices. However, sometimes the industrial site cannot provide a wired network or the cost of providing a wired network is relatively high. Contents of the invention [0003] The purpose of the present invention is to provide a data collection and processing system and method based on 3G network. In view of the fact that the current mobile network has covered almost all areas, in this case we choose 3G network for data transmission. For industrial sites, the real-time requirements a...
