Description
Technical Field
The invention relates to a method for improving remote transmission reliability of locally acquired information, and belongs to the technical field of communication.
Background
With the rapid development of wireless communication technology, more and more information acquisition and transmission are performed in a wireless manner, and especially under the condition that wired communication is difficult to deploy on site, wireless communication is widely applied due to convenience. After most front-end local information is collected, the local terminal is used for carrying out primary analysis and processing, and then the collected information is transmitted to the rear-end monitoring system in a wireless or wired mode, so that the stable operation of the local terminal plays an important role in reliable uploading of the collected information.
At present, a single set of local terminals are mostly adopted to transmit information acquired locally at the front end to a back-end system, and a double set of local terminals are adopted to transmit the same information in an active-standby mode in a special scene, but because the configuration of the double sets of local terminals often causes the increase of construction and operation and maintenance costs and the limitation of deployment space, the application in practical engineering is less. Although the reliability of the on-site terminal is greatly improved by continuous progress of the technology, the on-site terminal is sometimes affected by external factors such as electromagnetic interference, temperature and humidity and internal factors such as different service lives of various components due to a severe deployment environment, and thus, abnormal operation or failure can inevitably occur. Aiming at the importance of the wireless communication mode and the local terminal in practical application, the reliable transmission of the acquired information is further improved by a new technical means under the condition of not increasing new equipment and a deployment space, and the requirement of a back-end system on the front-end information is met, so that the method has practical application value. .
Disclosure of Invention
The invention aims to provide a method for improving the remote transmission reliability of locally acquired information, and solves the problem that a back-end system cannot reliably acquire locally acquired information under the condition of local terminal failure.
In order to achieve the above object, the scheme of the invention comprises:
the local terminal mainly comprises a power supply module, a wireless communication module, an information analysis processing module, a storage module and the like, and more than one terminal device is deployed on the site of the acquired object. A method for improving remote transmission reliability of locally acquired information comprises the following steps:
1) the local terminal carries out information interaction with an element for collecting the information of the collected object through the wireless communication module;
2) under normal conditions, the local terminal communicates with the fixed information acquisition element to acquire the information of the acquired object and uploads the acquired information to the back-end system;
3) when a certain local terminal goes wrong or the back-end system does not receive the information of the collected object sent by the local terminal within the set time, the back-end system sends an instruction to another local terminal near the preset local terminal, searches an information collecting element corresponding to the local terminal in a wireless mode, establishes communication between the new local terminal and the information collecting element, and sends the information of the collected object to the back-end system.
Furthermore, the information acquisition element is an element which is arranged on or near the body of the acquired object and acquires information required by a back-end system;
furthermore, under normal conditions, all on-site terminals deployed on site have one or more corresponding information acquisition elements and communicate with each other in a wireless manner;
furthermore, at least two local terminals on site can establish communication with the same information acquisition element in a wireless mode;
furthermore, under normal conditions, only one fixed local terminal communicates with the corresponding information acquisition element in a wireless mode, and other single or multiple local terminals capable of establishing communication with the information acquisition element are in a standby state;
further, after a certain standby local terminal receives an instruction of a back-end system, an information acquisition element establishing communication with the fault local terminal is actively searched in a wireless mode, and an instruction for acquiring information of an acquisition object is sent to the information acquisition element;
further, after receiving an instruction sent by the standby on-site terminal, the information acquisition element sends acquired information to the standby on-site terminal in a wireless mode, and the standby on-site terminal sends the acquired information to a back-end system;
furthermore, the local terminal may be in a standby state for some information acquisition elements, and may be in a master state for other information acquisition elements;
further, after the fault is over, the back-end system can normally receive the local terminal information corresponding to the information acquisition element firstly, then the back-end system sends an instruction that the information acquisition element acquisition object information is not acquired to the related standby local terminal, the communication connection between the standby local terminal and the information acquisition element is interrupted, and the standby state is recovered.
The invention has the advantages that when the local terminal corresponding to the information acquisition element firstly breaks down or the communication with the back-end system is abnormal, the standby local terminal is switched, and the wireless communication technology is fully utilized, so that on one hand, a new communication channel can be established under the condition of not increasing new equipment, and the reliability of remote transmission of locally acquired information is improved; on the other hand, the utilization rate of the on-site terminal can be greatly improved, the construction and operation and maintenance cost is saved, the occupied area of on-site terminal deployment is reduced, and certain economic and social benefits are brought.

Under normal conditions, each local terminal establishes normal communication with its corresponding information acquisition element, as shown in fig. 1.
2. When the local terminal i corresponding to the information acquisition element i is in fault or abnormal communication with the back-end system occurs, and the back-end system cannot receive the acquired object information sent by the local terminal i within the time delta t, the back-end system sends a command for searching the information acquisition element i corresponding to the local terminal i +1 near the local terminal i, and new communication relation between the local terminal i +1 and the information acquisition element i is established. The information acquisition element i sends the acquired object information to the local terminal i +1 in a wireless manner, and the local terminal i +1 uploads the acquired object information to the backend system, as shown in fig. 2.
3. When the communication between the local terminal i and the back-end system is recovered to be normal, the back-end system sends a command that the information acquisition element i does not acquire the object information to the local terminal i +1, the communication connection between the local terminal i +1 and the information acquisition element i is interrupted, the local terminal i still sends the object information acquired by the information acquisition element i to the back-end system, and the whole system recovers to the originally set normal operation state. The above communication flow is shown in fig. 3.
