Description

The accurate sensing of various data is a precondition for building an intelligent power plant, and the accurate sensing of various data depends on the real-time data acquisition of various intelligent terminals and robots and the large-scale coverage of a traditional communication network. Currently, common communication technologies mainly include mobile communication technologies such as bluetooth, WIFI network, big dipper, GPRS/CDMA and the like. Although the existing communication technology is applicable to both outdoor environments and indoor environments, building of an intelligent power plant involves various complex scenes, communication areas are simply divided indoors and outdoors, and communication equipment is arranged according to the communication areas, so that communication signals are blocked or lost, and a large number of areas which cannot be covered by a traditional communication network, namely 'blind areas', are generated in a plant area. Many data of the smart power plant are collected at fixed points, and workers use a mobile terminal to dynamically collect the data. If the collected data is located in the blind area in a certain period of time, the collected data cannot be transmitted. The blind area can not normally acquire the data needing dynamic acquisition while influencing daily communication of workers. Accurate data cannot be acquired, a lot of work cannot be carried out, and the intelligent power plant is difficult to build. Therefore, there is a need for a method and a system for a blind area ad hoc network of an intelligent power plant capable of implementing external communication in a blind area.
Disclosure of Invention
In order to solve the problems, the invention provides a blind area ad hoc network method and a blind area ad hoc network system of an intelligent power plant, and the method and the system can realize external communication in the blind area.
The technical scheme adopted by the invention is as follows:
a blind area ad hoc network method of an intelligent power plant comprises the following steps:
dividing communication areas of the intelligent power plant according to the coverage range of the first network; the first network is a conventional communication network; the communication area includes: a first communication area and a second communication area; the first communication area is an area covered by a first network; the second communication area is an area which is not covered by the first network, and the second communication area is covered by the second network; the second network is an ad hoc communication network;
establishing a communication connection; the communication connection includes: a first communication connection and a second communication connection; the first communication connection is formed by sequentially connecting a first terminal, a first network and a service platform; the first terminal is a terminal located in a first communication area; the second communication connection is formed by sequentially connecting a second terminal, a second network, a first network and a service platform; the second terminal is a terminal located in a second communication area;
and realizing data interaction between the terminal and the service platform through communication connection.
In particular, due to the diversity and complexity of smart power plant factory floor scenarios, traditional communication networks (first networks) often fail to cover certain areas of the factory floor, which are commonly referred to in the industry as "blind areas". Since the blind area is not covered by the conventional communication network, there is no communication signal in the blind area, and data cannot be received or transmitted. And the intelligent power plant needs to be constructed to operate equipment in each area of the power plant area as if the equipment is required to be operated. This relies on the communication network's full coverage of the factory floor and accurate collection of factory floor data. The blind area communication becomes the difficult problem that must be solved to build the wisdom power plant. In order to solve the problem that the blind area (second communication area) is difficult to communicate, the scheme adopts the following steps: firstly, scanning and shooting the whole factory area of the intelligent power plant, and constructing a virtual map by utilizing information obtained by scanning and shooting. Then, a traditional communication network is erected in the whole factory area, a second communication area is found out in the factory area according to the communication condition, and area division is carried out in the virtual map according to the second communication area. And then, according to the area division of the virtual map, erecting an ad hoc communication network (second network) in the traditional communication network, wherein the second network is arranged in a second communication area and is respectively connected with a second terminal and the first network. Finally, when the service platform issues the task to the second terminal, the task can be transmitted to the second network through the first network and then transmitted to the second terminal through the second network; and the second terminal acquires corresponding data according to the task and uploads the data to the service platform through the second network and the first network, so that data interaction between the second terminal and the service platform is achieved.
Further, the second network comprises: a plurality of second terminals and/or base stations; the second terminal is connected with a second terminal/base station; the second terminal/base station is connected with the first network/service platform; the second terminal is used for collecting, storing and transmitting data.
Specifically, the second network is configured by a plurality of second terminals and a base station. And the second terminal acquires data and sends the data to the base station, and the base station transmits the data to the service platform through the first network. The second network may also be constituted by the second terminal only. The terminal in the second communication area is connected with the adjacent terminal to form a path, so that the acquired data is transmitted to the terminal which is positioned at the edge of the second communication area and is connected with the first network, and the data interaction with the service platform is realized through the method. And because a base station does not need to be erected, the cost can be further saved. If the distance between the terminal in the second communication area and the service platform is close, the terminal can also directly perform data interaction with the service platform without passing through the first network. The transmission efficiency can be further improved and the response time of the machine can be reduced because the first network is not needed.
Further, after the communication connection is established, performing data interaction with the service platform by using the terminal, and before the communication function is realized, the method further includes:
detecting data throughput of the second terminal;
if the data throughput of the second terminal is greater than the threshold, carrying out transmission shunting on the data of the second terminal; the transmission shunting is to guide part of data in the second terminal with the data throughput larger than a threshold value to a new path for transmission; the new path is set according to the number of uses of the path, the length of the path, and the remaining energy of the second terminal on the path.
Specifically, the second network is formed by the second terminal, and the second terminal is used as a node integrating collection, storage and transmission functions, so that the situation of high load is easy to occur. To avoid this, each terminal sets a data throughput threshold. When the second network establishes communication connection with the outside, the second terminal can detect the data throughput of the second terminal in real time, and when the data throughput is greater than a preset threshold value, other adjacent terminals of the terminal can be connected with each other to form a plurality of new paths. The second network selects one of the plurality of new paths based on the number of times the path is used, the length of the path, and the remaining energy of the second terminal on the path. And the part of data in the second terminal with the data throughput larger than the threshold is transmitted by the selected new path, so that the load of the single terminal is reduced.
Further, after the communication connection implements data interaction between the terminal and the service platform, the method further includes:
and sending a standby instruction to the second terminal, and closing the functions which are not needed to be used currently.
Specifically, in order to reduce the energy consumption of the second network, each second terminal enters a standby state after data interaction, and the functions that are not needed to be used currently are turned off, for example: the transmission function of the output, etc.
Further, the implementing data interaction between the terminal and the service platform through the communication connection includes:
the method comprises the steps of positioning a terminal in real time, and sharing the positioning to a first network/a second network and a service platform;
receiving an instruction of a service platform, and acquiring data according to the instruction;
monitoring the equipment in real time to obtain the current running state of the equipment;
