However, the traditional operation and detection mode has low efficiency and single information source, and is difficult to meet the development requirement of the intelligent power grid, and the running state of the power transmission line is required to be sensed, monitored and early-warned in real time by an online monitoring means.
Regarding the current risk hidden trouble, most risks are finally manifested on deformation of the power transmission and transformation equipment no matter whether the tension of the lead changes caused by ice coating, strong wind and the like or the power transmission and transformation equipment is damaged caused by disasters such as landslide, debris flow, external damage and the like. The transmission line inevitably passes through special zones such as goafs, hillsides and the like, and is easy to cause the inclination of a pole tower, the cracking of a foundation and the deformation. Meanwhile, stress conditions such as tower inclination, wire icing, galloping and the like can cause abnormal strain of tower foot components. In the power transformation link, the abrupt change of the stress of the down-lead wiring terminal of the transformer substation represents abnormal stress of the down-lead; the capacitor has large capacity, high gravity center, large mass and high vulnerability, and the bulge deformation condition of the capacitor needs to be concerned.

Detailed Description
For a better understanding of the present invention, reference is made to the following description, drawings and examples.
The hardware of the sensing tag of the Internet of things comprises an MCU, a data communication module, a wireless charging module, a battery, an RFID chip, a deformation sensor and the like, and the sensing tag is analyzed and calculated in real time according to the data sensed by the deformation sensor combined in the sensing tag of the Internet of things, so that the equipment deformation monitoring of the fixed position of the tag is realized, meanwhile, an inspection staff reads the equipment state information through the RFID and simultaneously carries out the charging process of a tag system, the operation and maintenance burden is not additionally increased, the service life of the tag is greatly prolonged, the workload of replacing the battery by the tag is reduced, and the equipment maintenance flow is optimized.
The deformation sensor design basis of thing networking perception label is octagonal ring elastomer structure, combines deformation sensor and thing networking perception label body fixedly or integrated into one piece, forms the thing networking perception label that is used for equipment deformation monitoring promptly, as shown in fig. 1, thing networking perception label includes thing networking perception label body 1 and deformation sensor elastomer 2, thing networking perception label body 1 includes MCU microcontroller, RFID chip, wireless charging module, bluetooth communication circuit, circuit devices such as rechargeable battery, deformation sensor elastomer 2 both sides possess the location fixed orifices for fix overall structure on the surface that power equipment needs to carry out deformation monitoring, deformation sensor elastomer 2 both sides are the deformation of octagonal ring structure, and its upper surface is the plane, and the lower surface is the arc, and the upper and lower surface department thickness is thinnest in 45 degrees departments in both sides to reach deformation maximum effect, is provided with first strain gauge 3 at the plane middle part on deformation sensor elastomer 2 left side, and the plane middle part on deformation sensor elastomer 2 right side is provided with second strain gauge 4, and the plane middle part on right side is provided with third strain gauge 6-fourth strain gauge 6, and the cambered surface 2 is provided with the cambered surface 6-fourth cambered surface 6. The four strain gauges are connected into a Wheatstone full bridge form and are powered by rechargeable batteries of the sensing tag of the Internet of things.
The connection form of the strain gage is shown in fig. 2, and when the surface of the equipment is deformed, the positioning holes at two sides can move relatively. When the elastic body is stretched to two sides, stress concentration phenomenon is generated at the attachment part of the strain gauge, and the surfaces of R1 and R2 are compressive stress; the surfaces of R3 and R4 are tensile stress. Correspondingly, the resistance values of R1 and R2 are reduced, and the resistance values of R3 and R4 are increased. And applying certain excitation voltage to two ends of the bridge, and simultaneously monitoring the voltage between the wheatstone bridge arms to sense the deformation change of the equipment. Because the four strain gauges adopt a full bridge connection method, the output voltage V is as follows:
where U is the excitation voltage, R1 is the resistance of the strain gauge 3, R2 is the resistance of the strain gauge 4, R3 is the resistance of the strain gauge 5, and R4 is the resistance of the strain gauge 6.
It can be seen that the output voltage varies with the resistance of the strain gauge, and that R1 and R4 are always opposite in magnitude. Therefore, this bridging method has maximum sensitivity. The surface deformation condition of the power equipment can be sensitive.
The sensing tag of the Internet of things is an embedded system, wherein a rechargeable battery is used for supplying power to the embedded system and is used as an excitation voltage source U of the deformation sensor. After the MCU detects the output voltage signal of the deformation sensor, alarm data can be sent by two methods of Bluetooth or RFID near field communication. When a person patrols and examines, the deformation data can be read in a period of time through the RFID hand-held machine; the device information can be written into the tag through the Bluetooth function and updated in time, so that the tag becomes a carrier of the whole life cycle information of the power device, meanwhile, a patrol inspector can charge a rechargeable battery in the sensing tag of the Internet of things through a wireless charging module in the RFID handheld machine when reading the device state information, thereby greatly prolonging the service life of the tag, reducing the workload of replacing the battery of the tag, not additionally increasing the operation and maintenance burden and optimizing the maintenance flow of the device.
