Method for improving remote transmission reliability of in-situ acquired information

Abstract

The invention relates to a method for improving remote transmission reliability of in-situ acquired information, which comprises the following steps: under normal conditions, an in-situ terminal communicates with a fixed information acquisition element of an acquired object in a wireless mode, acquires the information of the acquired object and uploads the information to a back-end system. And in a set time, when the back-end system cannot receive the information sent by the terminal, an instruction for searching the corresponding information acquisition element is sent to another local terminal near the terminal, so that the new local terminal establishes wireless communication with the corresponding information acquisition element, acquires the information of the acquired object and uploads the information to the back-end system. And after the communication between the back-end system and the local terminal which interrupts the communication is recovered, an instruction for interrupting the communication between the local terminal and the corresponding information acquisition element is sent to the new local terminal. By switching the standby local terminal, the remote transmission reliability of the information acquired by the front end and the utilization rate of the terminal can be improved without adding new equipment, the number of deployed terminals is reduced, and the construction, operation and maintenance cost is saved.

Description

technical field [0001] The invention relates to a method for improving the reliability of remote transmission of locally collected information, which belongs to the technical field of communication. Background technique [0002] With the rapid development of wireless communication technology, more and more information collection and transmission are carried out wirelessly, especially when it is difficult to deploy wired communication on site, wireless communication has been widely used due to its convenience. After most of the front-end on-site information is collected, the on-site terminal performs preliminary analysis and processing, and then transmits the collected information to the back-end monitoring system in a wireless or wired manner. Uploading plays a very important role. [0003] At present, most of the information collected on-site by the front-end is transmitted to the back-end system by using a single set of on-site terminals. It often results in increased co...
