Abstract
The present invention provides a kind of capacitor temperature detection means based on Internet of Things, temperature acquisition terminal includes temperature sensor and single-chip microcomputer, temperature sensor is by after the temperature parameter collection of the capacitor top shell of measured point, the analog signal of output is progressively sent to amplifying circuit, low pass filter and A/D converter, then again by single-chip microcomputer according to the skin temperature of capacitor and the corresponding relation of internal temperature, it is equivalent go out capacitor internal temperature, and the data signal that A/D converter is exported is transmitted to coordinator node, and information is quickly uploaded into PC by RS232 serial ports by the good form of predefined, parse and show immediately.Instant invention overcomes the deficiencies in the prior art, the on-line monitoring of the sub- temperature of capacitor temperature, capacitor terminal and capacitor running current is realized, the accurate real-time running state for grasping capacitor.
Description
Technical field
The present invention relates to capacitor detection technique field, and in particular to a kind of capacitor temperature detection dress based on Internet of Things
Put.
Background technology
Its Solid dielectric breakdown field strength of capacitor is influenceed very big by capacitor internal temperature, it is therefore desirable to which its temperature is carried out
Monitoring.But it is relatively difficult to achieve that capacitor internal temperature is measured because capacitor internal element is sealed in inside steel plate box, in operation,
Also it is unrealistic.And the too high capacitor life-span that easily causes of internal temperature is reduced, or even there is thermal breakdown and cause to damage；Meanwhile,
If capacitor internal temperature is too high, dielectric can decompose a large amount of gases, capacitor case expansion, can even be produced when serious
Blast.
The content of the invention

In view of the shortcomings of the prior art, the invention provides a kind of capacitor temperature detection means based on Internet of Things, gram
The deficiencies in the prior art have been taken, the online prison of the sub- temperature of capacitor temperature, capacitor terminal and capacitor running current is realized
Survey, the accurate real-time running state for grasping capacitor.
(2) technical scheme
To realize object above, the present invention is achieved by the following technical programs：
A kind of capacitor temperature detection means based on Internet of Things, including single ZigBee telegons, PC and temperature are adopted
Collect terminal, the temperature acquisition terminal includes temperature sensor and single-chip microcomputer, and temperature sensor is by the capacitor top of measured point
After the temperature parameter collection of shell, the analog signal of output is progressively sent to amplifying circuit, low pass filter and A/D converter,
Then again by single-chip microcomputer according to the skin temperature of capacitor and the corresponding relation of internal temperature, it is equivalent go out capacitor internal temperature,
And the data signal that A/D converter is exported is transmitted to coordinator node, resting state is again introduced into immediately after, to greatest extent
Energy consumption is reduced, extends terminal node power supply cruising time, the coordinator node in network is responsible for collecting each temperature acquisition node
Information, and information is quickly uploaded into PC by RS232 serial ports by the good form of predefined, parse and show immediately
Come.
Described temperature acquisition terminal is additionally provided with flash storage, if information data can be propped up beyond wireless network
The transmission range held, data can be stored temporarily in flash storage by that.
The temperature acquisition terminal is additionally provided with output alarm unit and is connected by alarm lamp with single-chip microcomputer.
Described single-chip microcomputer is CC2530 chips.
(3) beneficial effect
The embodiments of the invention provide a kind of capacitor temperature detection means based on Internet of Things.Possesses following beneficial effect
Really：The present invention should build network first by coordinator node, wait the networking request of each self terminal acquisition node；Terminal node
After checking adds network, the data that temperature sensor is collected are by wireless network upload transfers to coordinator node；
Coordinator node is received after packet, carries out resolve packet, and by serial ports by temperature information and child node address etc.
Effective information is stored and is shown on monitoring interface；Realize that the sub- temperature of capacitor temperature, capacitor terminal and capacitor are run
The on-line monitoring of electric current, the accurate real-time running state for grasping capacitor.So as to avoid capacitor and capacitor terminal as far as possible
Son connection is insecure, and excessively stream etc. causes capacitor excess temperature failure or even further expands and cause even more serious accident event
With unnecessary loss occurrence.
Embodiment
