Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
Present system structure is as shown in Figure 1. First the Monitoring and Controlling layer of the present invention sends broadcast to the information routing layer in its territory, data collection layer, and whether inquiry has network request to add.
The data concentrator that information routing layer application adds sends addition request to Monitoring and Controlling layer after receiving broadcast, Monitoring and Controlling layer sends key authentication request to the data concentrator that application adds, the data concentrator that application adds sends key to Monitoring and Controlling layer after receiving key authentication request, if key is correct, Monitoring and Controlling layer is asked by the addition of this data concentrator, and distributes corresponding ID territory for it.
The data concentrator of information routing layer is broadcasted to the data collection layer transfer in its subdomain, and whether inquiry has monitoring device application to add, if there being the monitoring device that application adds, then this device sends to the data concentrator in its territory, place and adds request. The data concentrator in this territory sends key authentication request to the monitoring device that application adds, and the monitoring device that request adds sends authentication secret to Monitoring and Controlling layer after receiving key authentication request. If key is correct, data concentrator sends territory monitoring device extended requests to Monitoring and Controlling layer, and Monitoring and Controlling layer sends key authentication request to this sub-field data concentrator, and data concentrator sends fore device key and domain key to Monitoring and Controlling layer. The whether available free ID in this territory of the correct post analysis of Monitoring and Controlling layer authentication secret, if there being unallocated ID, for the monitoring device distribution ID that application adds. If this territory does not have idle ID, Monitoring and Controlling layer expands ID territory for this subdomain, and for being newly added equipment distribution ID, as shown in Figure 2.
Monitoring and Controlling layer sends the work state information of the monitoring device of query command, the data concentrator of solicited message routing layer and data collection layer after network topology inquiry to information routing layer and data collection layer.
As it is shown on figure 3, Monitoring and Controlling layer after network topology inquiry to information routing layer and data collection layer dispensing device state query command. Data concentrator listens to the query command of Monitoring and Controlling layer and returns local state information. If certain numeric field data concentrator does not return state response, monitoring management main frame sends query command to this numeric field data concentrator continuously, and simultaneously the data concentrator main control unit of information routing layer is initially set two working cycle and will automatically restart without query command. After Monitoring and Controlling layer 5 working cycle of continuous inquiry, the still nonreply of this subdomain then wakes standby communication facility up, and records this territory Master Communication Equipment and break down warning. If system still nonreply after standby communication facility startup, system will send fault alarm. Information routing layer is to the data collection layer transfer query command in its ID territory. Data acquisition bed device resolves this query command after listening to the query command of information routing layer transfer, monitor device main control unit return mechanism status information, and controls wireless device and enter and intercept state. If the monitoring device in this territory does not return state response, monitoring management main frame sends query command to this monitoring device continuously by information routing layer. Simultaneously the monitoring front end main control unit of data collection layer is initially set two working cycle and will automatically restart without query command. After Monitoring and Controlling layer 5 working cycle of continuous inquiry, this monitoring device still nonreply then wakes this monitoring device standby communication facility up, and records this monitoring device Master Communication Equipment and break down warning. If system still nonreply after standby communication facility startup, system will send fault alarm.
The Monitoring and Controlling layer of the present invention periodically sends data request command and control command to data collection layer, data collection layer receives control command and data request command, it is judged that command information gathers monitoring point status information effectively afterwards and sends information data by wireless module. The data message of intelligent monitor system overall analysis system front-end collection also controls the working method of monitoring front end.
As shown in Figure 4: Monitoring and Controlling main frame periodically to information routing layer and data collection layer transmitting control commands by data concentrator, is controlled information routing layer and carries out information router, controls data collection layer and gathers the status information of monitoring point. The data message that the comprehensive research and application front end of Monitoring and Controlling layer is passed back, and the working method according to the data message adjustment monitoring front end passed back. When the state parameter result of calculation of Monitoring and Controlling layer analysis monitoring point low less than initial set threshold value 80% time, system enters waiting state, waits the next working cycle. If analyze result more than set threshold value 80%, whether the further analysis result of system is more than initially setting threshold value, if more than setting threshold value, system sends alarm signal. If analysis result is more than setting the 80% of threshold value and less than setting threshold value, system shortens the working cycle of inquiry and data request command. System is set into waiting state according to the new working cycle, waits the next working cycle. The initial setting limit value setting threshold value and adjustment, warning can according to practical situation adjustment.
The present invention can comprehensively analyze the data message of each monitoring device, adjusts the working method of monitoring front end, it was predicted that with the generation of monitoring transmission line of electricity disaster. Intelligent monitor system monitors the weather information such as the wind speed of front-end collection, wind direction, rainfall, air humidity according to microclimate, comprehensively analyze and predict the meteorological condition near monitoring point whether meet wave, condition that icing is formed. Meteorological condition near monitoring point reached circuit wave, the prerequisite of icing, system controls to adjust the working cycle of the data acquisition unit of power transmission line swaying monitoring front end, icing monitoring front end and respective regions, closely pays close attention to the state change of the transmission line of electricity in this region. When the data of Monitoring and Controlling layer analysis show by or have occurred and that transmission line of electricity meteorological disaster, the video monitoring device in monitoring this region of system start-up carries out actual observation, observe further this region icing to occur, the situation of meteorological disaster such as waves, send alarm signal to the staff of monitoring station, and the data gathered, analyze are stored comprehensively store data base.
The notices such as the present invention can monitor the ambient temperature near the monitoring point of device collection according to microclimate or higher level assigns circuit lacuna, open circuit adjust the working method of temperature of electric transmission line monitoring device, this circuit running status of close observation, it is to avoid the excessive ground connection of conducting wire sag occurs or contact point is overheated etc. causes that the accident of line broken circuit occurs.
