specific Embodiment approach 1
[0037] Specific embodiments 1. An end-to-end communication method for power outage maintenance personnel, which includes the following steps:
[0038] Step 1. Install a wirelesscommunication device on each line maintenance personnel who intends to participate in the communication, and record it as a node AP;
[0039] Step 2. Store the wireless networklayout of each community and the historical data of the strength of various wireless networks in the control center, and list them in order from strong to weak;
[0040] Step 3. In a communication cycle, if a certain node AP intends to initiate end-to-end communication, the node AP sends an end-to-end communication request packet to the control center, and the end-to-end communication request packet includes: its own ID, The ID of another communication node, the longitude and latitude of the current coordinates, and the type of business to be communicated;
[0041] Step 4, the control center receives the communication request p...
specific Embodiment approach 2
[0053] Embodiment 2. This embodiment is a further limitation of Embodiment 1. In step 11, the network allocation data packet sent by the control center to the initiating node and another communication node also includes: an alternative network; the control center, the initiating The node changes the business type with another communication node, and the three parties switch to the alternative network for end-to-end communication.
specific Embodiment approach 3
[0054] Specific implementation mode three, the end-to-end communication method for power-off maintenance personnel, which includes the following steps:
[0055] Step 1. Install a wireless communication device on each line maintenance personnel who intends to participate in the communication, and record it as a node AP;
[0056] Step 2. Store the wireless networklayout of each community and the historical data of the strength of various wireless networks in the control center, and list them in order from strong to weak;
[0057] Step 3. In a communication cycle, if a certain node AP intends to initiate end-to-end communication, the node AP sends an end-to-end communication request packet to the control center, and the end-to-end communication request packet includes: its own ID, The ID of each communication node, the longitude and latitude of the current coordinates, and the type of business to be communicated;
[0058] Step 4, the control center receives the communication re...

Abstract
A power failure maintainer end-to-end communication method relates to a power failure maintainer end-to-end communication technology. The problem of low communication reliability in the end-to-end communication process of the maintainer and the outside is solved. In the method, before the maintainer and the outside perform end-to-end communication, a control center selects a proper wireless network according to the type of a service reported by the maintainer and by combining the signal intensity of a housing estate of the maintainer, and communicates with the maintainer in the selected wireless network. When the type of the service in the end-to-end communication process is changed, three or more parties can perform end-to-end communication through an alternative network. According to the power failure maintainer end-to-end communication method, the frequency spectrumutilization rate is high and the communication reliability is greatly improved. The power failure maintainer end-to-end communication method is suitable for end-to-end communication occasion of the maintainer.
Description
technical field [0001] The invention relates to an end-to-end communication technology for power-off maintenance personnel. Background technique [0002] Power line maintenance means that the switches on each side of the line are in the cold standby or maintenance state and the line outlet switches are all in the off position, or all the knife switches connected to the line are in the off position, the line is not live; the line is highly resistant to high voltage The side knife switch is opened, the PT low-voltage side of the line is disconnected, and the grounding knife switch on each side of the line is in the closed position (or the grounding wire is hung); if there is no special requirement, the line protection will stop; for lines with series compensation devices, series compensation The device should be in cold standby or maintenance state. [0003] But at present, in many cases, the working place of the line maintenance personnel is in a place with poor signal condi...
