Abstract
The invention relates to a power transmission line forest fire monitoring system based on a satellite receiving system, which comprises a satellite receiving antenna (1), a low noise amplifier (2), a data signal feeder line (3), a data input card (4), a first computer (5), a second computer (6) and a third computer (7) sequentially connected in series. The system has the advantages that various kinds of remote sensing satellite information broadcast by national satellites and meteorological satellites, the type and the quantity of received satellite information can be freely selected according to requirements, and the cost performance is high; the degree of automation is high, the requirement of timeliness can be guaranteed, and real-time early warning can be realized; system hardware is not influenced by satellite change and can be upgraded freely; and high-accuracy time reference can be provided for satellite tracking and data input, and the system stability is very reliable.
Description
Technical field
The invention belongs to the electrical engineering technical field, relate in particular to a kind of transmission line of electricity mountain fire monitoring system based on satellite receiving system.
Background technology
The mountain fire disaster takes place frequently, and transmission line of electricity is often crossed over the easy location of sending out of mountain fire, in case mountain fire takes place, the atmospherical discharges that it caused will cause the transmission line of electricity tripping operation.And tripping operation in a single day, the subproduct dirt of being insulated influences, and transmission line of electricity desire combined floodgate will be very difficult, even cause nonvolatil fault, have a strong impact on power supply quality, and the tripping operation that visible mountain fire causes is bigger than the tripping operation destructiveness that thunderbolt causes.Along with fast development of national economy, every profession and trade is also increasing to the demand of electric power, and is also increasingly high especially to the requirement of power supply quality, so the security of operation of power networks and stability seem particularly important.In order to improve power supply quality, improve social benefit, to reduce economic loss, need facility and the measure of releasing the monitoring of transmission line of electricity mountain fire as early as possible badly, in time give the alarm so that get the jump on the very first time of mountain fire generation.
Summary of the invention
The technical matters that the present invention will solve is; Deficiency to the prior art existence; A kind of transmission line of electricity mountain fire monitoring system based on satellite receiving system is provided; This system's small investment, operation and maintenance are simple, can satisfy near the demand of the large tracts of land mountain fire monitoring and warning transmission line of electricity, prevent that effectively the tripping operation accident that the mountain fire disaster is brought out from taking place.
Technical solution of the present invention is; Said transmission line of electricity mountain fire monitoring system based on satellite receiving system; Referring to Fig. 1, it is as shown in Figure 1 takes in card 4, first computing machine 5, second computing machine 6, the 3rd computing machine 7 by satellite earth antenna 1, low noise amplifier 2, data-signal feeder line 3, data and is composed in series successively.
Principle of work of the present invention is: the said satellite earth antenna 1 of native system is used to receive the data of the transmission relation circuit mountain fire information of satellite real-time Transmission, and exports the data-signal that is received to said low noise amplifier 2; This low noise amplifier 2 exports the input end that said data are taken in card 4 to through data-signal feeder line 3 after the data-signal that receives is strengthened; The output terminal of this data absorption card 4 is transported to data-signal the input end of said first computing machine 5 of being responsible for the reception data again; 5 pairs of data that obtain of this first computing machine are carried out after the pre-service will passing through data after the verification through its output terminal and are transported to said second computing machine 6 and carry out processing such as projection, mapping; Generate fiery dot information and satellite cloud picture thereof; This second computing machine 6 is with obtain fiery dot information data are transported to said the 3rd computing machine 7 through its output terminal input end then; The fiery point data that the 3rd computing machine 7 promptly transmits according to second computing machine 6; Calculate the distance of fiery point and circuit and shaft tower in conjunction with the geographical wiring diagram of electrical network, issue fiery dot information and the early warning information of relevant transmission line of electricity of the transmission relation circuit mountain fire of above-mentioned satellite real-time Transmission, promptly circuit and the shaft tower to danger sends warning information; Make relevant unit can in time start the emergent management prediction scheme; Even mountain fire is dropped to the minimum threat of eliminating mountain fire to transmission line of electricity fully to the influence of transmission line of electricity, thereby reduces the grid power blackout accident that causes because of mountain fire, improve the safe and stable operation level of electrical network.
The invention has the beneficial effects as follows:
1), can obtain the multiple remote sensing satellite data of national satellite weather satellite broadcasting simultaneously, and can be as requested the kind and the quantity of selective reception satellite data flexibly, cost performance is high;
2), the system automation degree is high, can ensure that real-time monitoring is professional to ageing requirement, the real-time early warning of realization circuit;
3), system hardware is not changed by satellite influences, and can exempt follow-up HardwareUpgring expense;
4), the operation of total system is on the basis of unified time, to carry out, and therefore can be Satellite Tracking, data are taken in that the high precision time benchmark is provided, and the stability of system is very reliable.
