Description
Technical Field

A common power transmission line video monitoring system in the market at present mainly comprises a high-definition camera, a wireless communication network, a solar cell, a video monitoring master station system and the like. Because a high-definition camera needs high-bandwidth channel transmission and a power transmission line is located in a remote area, a power transmission line video monitoring system usually adopts a 2.4G/5.8G wireless ad hoc network communication mode at present from the viewpoint of flow rate charge and network reliability, and the network topology is generally a chain structure according to the line trend characteristics.
Installing wireless convergence equipment on a transformer substation side for realizing the tandem connection of a plurality of line chain type communication networks; an upper wireless device, a lower wireless device, a high-definition camera and a solar battery are arranged on the power transmission line tower. The upper-connection wireless equipment is connected with the wireless convergence equipment on the transformer substation side in a wireless mode; the lower-link wireless equipment is connected with the upper-link wireless equipment at the position of the line tower in a wireless manner; the upper wireless equipment and the lower wireless equipment are connected by a twisted pair; the high-definition camera is connected to the uplink wireless equipment through a twisted pair; the solar battery respectively establishes a direct current power supply for the upper wireless device, the lower wireless device and the high-definition camera.
Because the transmission line tower does not usually have a commercial power alternating current power supply, the solar cell can not obtain electric energy in rainy days and nights. Under the condition that the capacity of the solar battery is limited, if a high-definition camera and wireless communication equipment on a power transmission line are always in an operating state, the battery power supply time is greatly shortened. Therefore, from the perspective of energy consumption control, some devices in the market currently adopt a sleep power saving mode, that is, the line side device enters a sleep standby state within a specified time after completing operations or after receiving a sleep command, so as to save electric energy. After the device is dormant, the prior art in the market at present mainly has two modes of timing wake-up and sensor wake-up. The timing awakening means awakening the sleeping equipment according to a set time point or time interval; the sensor wake-up refers to waking up the sleeping device according to signals detected by sensors such as radar and infrared.
The prior art mainly has the following problems:
1. the remote active random awakening function is not supported, and the requirement that power transmission line operators awaken a specified camera to acquire images at any time in an emergency cannot be met. And if the high-definition camera and the wireless communication equipment on the transmission line side are in a working state consistently, the service time of the battery is greatly shortened.
2. The energy management mode does not match the power transmission line chain type networking and needs further optimization to save electric energy. According to the characteristics of the trend of the power line, the current power transmission line video monitoring system mainly adopts a chain type networking structure. Under the structure, equipment on a line tower mainly works in two modes: "intermediate node mode" and "end node mode". In the prior art, refined power supply management of the transmission line tower equipment according to an intermediate node mode and a tail end node mode is not achieved so as to achieve the purposes of saving energy and prolonging the service time of a solar battery.

it should be noted that, the power transmission line name and the tower number familiar to the operator are used as the device name, the device code refers to step S100, and the communication number adopts the SIM card number adopted by the NB-IoT module installed at the tower. An example of the established correspondence table is as follows:
s300: adding a channel index and a working mode in the corresponding table to generate a channel routing index and a working mode instruction list;
it should be noted that, based on the correspondence table in step S200, a channel route index and an instruction list for issuing an operation mode are automatically generated. The generation process is as follows:
s301: analyzing the equipment codes of the line side network element node equipment, and acquiring wireless convergence equipment codes, chain network codes and equipment sequence number codes in the equipment codes;
it should be noted that, the network element node device code (for example, H1-L1-N3) is obtained according to the coding rule; the wireless convergence device code (e.g., H1), the chain network code (e.g., L1), and the device serial number code (e.g., N3) in the device codes are parsed and extracted, respectively.
S302: keeping the wireless convergence device codes and the chain network codes unchanged, sequentially generating device codes of all nodes on a chain network path required to pass by reaching the line side network element node device from 1, and sequentially filling the device codes corresponding to the line side network element node device and the device codes of all nodes on the passing chain network path into a channel index according to a passing sequence;
it should be noted that, keeping the wireless convergence device code (e.g. H1) and the chain network code (e.g. L1) unchanged, the device codes of all nodes on the chain network that need to be routed to the line side network element node (e.g. H1-L1-N1, H1-L1-N2, H1-L1-N3) are automatically generated in sequence on the basis of integers, and the "channel routing index" field is filled.
S303: and setting the working modes corresponding to the equipment codes of all nodes on the passed chain network path as the working mode of the intermediate node, and setting the working modes corresponding to the equipment codes of the line side network element node equipment as the working mode of the end node.
It should be noted that, except that the operation mode of the last network element node is automatically set as the "end node", the operation modes of the other network element nodes are automatically set as the "intermediate nodes". The following table specifically shows:
as shown in fig. 3, the operator calls the "500 kV sweet-scented-nail line N5 tower" video as an example. The master station module sends an intermediate node mode instruction to a communication card corresponding to an NB-IoT module of a 500kV Guiwen A line N1 tower according to a channel route index and a working mode instruction list, informs the tower that an uplink wireless device 1 and a downlink wireless device 1 are started, and a high-definition camera 1 is continuously in a dormant state; meanwhile, an end node mode instruction is sent to a communication card corresponding to an NB-IoT communication module of a 500kV Guiwen A line N5 tower, an uplink wireless device 2 and a high-definition camera 2 on the tower are informed to be started, and a downlink wireless device 2 is continuously in a dormant state; all equipment on the 500kV Guiwen Jia line N9 tower are in a dormant state continuously because the equipment does not receive the instruction. Through the steps, one-key quick calling of the appointed camera is realized, and unnecessary energy consumption of each device on the link line can be reduced.
The embodiment provides an energy-saving device for chain type wireless ad hoc network equipment, which can automatically establish a chain type network channel required by terminal data transmission by establishing a channel route index and a working mode instruction list through a main station module, realize that an operator remotely wakes up an appointed high-definition camera by one key at any time, realize refined power supply management of power transmission line tower equipment according to an intermediate node mode and an end node mode, and realize one-key quick calling of the operator to the high-definition camera appointed by the line side.
