Technical field
The utility model relates to a kind of temperature measurement system, relates in particular to a kind of operation of power networks device temperature sensory perceptual system based on technology of Internet of things.
Background technology
The safe operation of electric system is related to the stable of the national economic development and people's lives.Along with modern power systems develops rapidly to high voltage, large unit, jumbo direction, people are also more and more higher to the requirement of power system power supply reliability.Characteristics when power equipment breaks down are that temperature variation is comparatively slow at ordinary times, mostly are greatly progressive formation; When yet fault occured, temperature often formed again sudden change, and gradual change is to sudden change.So the temperature real time and on line monitoring to the easy hot spot of large electric current (contact, bus contact joint and high-voltage cable joint etc.) is extremely important.
The temperature sensing means that operation of power networks equipment is commonly used is employing temperature display wax sheet thermometric, accuracy is low, poor reliability, can not carry out quantitative test, little with reference to using value, and temperature display wax sheet in use easily comes off, later maintenance tour workload is large, the relevant device of need stopping transport when safeguarding, and invisible cost is difficult for estimating; Another kind of for utilizing the infrared thermometer thermometric of light (infrared) radiation characteristic, it can measure temperature between 0～200 ℃, but owing to needing optical device, the elements such as high-tension switch cabinet block mutually more specific occasion use not too convenient, and indirectly obtain its accuracy of temperature data by infared spectrum and can not meet the demands, Computer Recognition Technology level to infared spectrum can't replace artificial cognition, automaticity is not high, the cost of thermal infrared imager is higher simultaneously, again must manual patrol, the after-cost is large, applies certain limitation.Also have a kind ofly for optical fiber temperature-measurement, adopt the optical fiber transmission delivery signal, its temperature sensor is installed in the surface of charged object, is connected with optical fiber between temperature measurer and temperature sensor.But that optical fiber has is easy to break, easily broken, the defective of non-refractory, and behind the accumulation dust insulativity is reduced, and its difficulty that connects up in cabinet is larger, and cost is high.
As seen, existing conventional temperature sensing means can't satisfy the demand to operation of power networks equipment temperature of key part Real-Time Monitoring.Develop a kind of temperature measuring equipment applied widely, safe and reliable, can Real-Time Monitoring major equipment (particularly to provision for sealing inside) key point running temperature become electric system practical problems of being badly in need of solving, also be improve the electrical equipment reliability in the urgent need to.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of operation of power networks device temperature sensory perceptual system based on technology of Internet of things to be provided.
The utility model is achieved through the following technical solutions:
A kind of operation of power networks device temperature sensory perceptual system based on technology of Internet of things, include main control system, a plurality of wireless base stations and a plurality of radio temperature sensor, described wireless base station is by control module, the RS-485 interface, wide input DC/DC D.C. regulated power supply, 2.45GHz digital RF transceiver, the IP68ASA shell, gain directional antenna and omnidirectional antenna form, described radio temperature sensor is by little power consumption MCU, digital temperature sensor, 2.4GHz digital RF transceiver, the inferior battery of high temp. lithium, IP68 stainless steel casing and antenna form, described a plurality of wireless base station and a plurality of radio temperature sensor are one to one, radio temperature sensor and wireless base station carry out wireless transmission by 2.4GHz numeral RF transceiver, and described a plurality of wireless base stations all are connected with described main control system by the RS-485 interface.
Each radio temperature sensor all has numbering, and the numbering of each radio temperature sensor all is kept in the storer of described main control system.
The configuration monitoring software is arranged in the main control system, integrated various communications protocol and the management platform with the software function improved, possess patterned human-computer interaction interface and complete stable database, be mainly used to receive the temperature anomaly warning that the thermometric workstation sends, and process, inquire about, add up, analyze the thermometric total data of native system.Can finish the temperature treatment of the whole cables of 220kV level transformer station, bus joint, visual plant, also can embed other management and control function, realization effectively realizes many information fusion and integrated in a plurality of management roles of single platform operation, reduces user's TCO.
The temperature data that automatic reception radio temperature sensor in wireless base station sends, and the temperature data uploading thermometric workstation that handle is received behind the reading order of receiving the thermometric workstation.Owing to being subjected to the restriction of site environment, wireless transmission distance can be hundreds of rice in theory, actual only have tens meters, and one group of radio temperature sensor is only managed in each data transmission base station, and the numbering of these radio temperature sensors needs configured in advance to be saved in the flash storer of terminal.
Node in each temperature monitoring target is installed a radio temperature sensor, and this sensor is measured the temperature of position automatically every setting-up time, and the temperature data that records is sent output with wireless signal.Each radio temperature sensor has unique 32b1ts numbering (ID number), the infield that needs to distribute, record each sensor during actual the use, and deposit in the configuration file of main control system with numbering.
The radio temperature sensor Timing measurement is the running temperature of this monitoring point once, and environment temperature sensor is automatic measures ambient temperature also, and these temperature datas are transferred to the base station by the 2.4GHz wireless channel, and these data can be preserved, be recorded in the base station.
Main control system can be regularly by RS one 485 each base station of bus poll, and each base station is transferred to main frame with the temperature data of receiving, main control system is processed the bus temperature data and preserve.The relative temperature rise of the relative temperature rise of main frame by compare facilities and environment, indoor and outside atmosphere, analyze possible overheat condition, send in advance early warning signal, remind managerial personnel to process, also can a plurality of alerting signals are provided for public observing and controlling screen by relay.
The utility model has the advantages that: the utility model can satisfy the technical need that the running temperature of the equipment such as electrical equipment and power cable, joint, capacitor, reactor is realized on-line monitoring, and the informationization that can be the operation of power networks repair based on condition of component provides the basic data support, not only saved a large amount of human and material resources, have also that temperature measurement accuracy is high, fast response time, easily install, the advantages such as volume is little, round-the-clock, real-time online, nothing is failed to report, antijamming capability is strong.
