Detailed Description
The present invention is described below in terms of embodiments in conjunction with the accompanying drawings to assist those skilled in the art in understanding and implementing the present invention. Unless otherwise indicated, the following embodiments and technical terms therein should not be understood to depart from the background of the technical knowledge in the technical field.
Example 1: the utility model provides a substation equipment tours and uses hand-held type mobile terminal, refers to fig. 1, includes casing 1, control processor, display 2, keyboard 3, far-infrared thermal imaging camera, current transformer and voltage transformer, control processor sets up in the casing, far-infrared thermal imaging camera is fixed on the casing, control processor respectively with the display far-infrared thermal imaging camera current transformer the voltage transformer electricity is connected.
Preferably, the far infrared thermal imaging camera adopts a microbolometer type detector and a catadioptric secondary imaging optical structure.
The infrared imaging system comprises an optical system, an infrared detector, an electronic system, an image processing system, a mechanical structure frame and the like. Firstly, infrared radiation emitted by an object is transmitted into an optical system through the atmosphere; the optical system only allows infrared radiation with limited wavelength to pass through and effectively inhibits background radiation around an object; when the infrared detector receives the infrared radiation from the optical system, the infrared radiation is converted into weak electric signals, and the weak electric signals are amplified and then injected into a reading circuit to be output to a post-stage electronic system; after receiving the analog signal output by the detector, the electronic system sequentially performs processes of impedance conversion, conditioning amplification, analog-to-digital conversion, signal processing and the like on the signal, and finally stores and displays the infrared image.
The infrared detector can be classified into a refrigeration type and a non-refrigeration type according to different working conditions. The microbolometer type detector belongs to a non-refrigeration type infrared detector, is well compatible with a semiconductor manufacturing process, and is very suitable for large-scale integration and production.
Common structural forms of the infrared optical system include refraction primary imaging, refraction secondary imaging, refraction-reflection primary imaging, refraction-reflection secondary imaging, and total reflection secondary imaging. The catadioptric secondary imaging structure is a typical structural form of airborne and missile-borne photoelectric imaging equipment, the primary mirror and the secondary mirror bear most of focal power, the focal length of the relay lens group is generally very small, the caliber of the relay lens group is not large, and chromatic aberration correction is relatively easy; meanwhile, the plane reflector is used for turning the light path, so that the volume and the mass of the optical system are reduced, and the total length of the optical system can be generally less than 0.8 time of the focal length of the optical system. The design form of a catadioptric optical system can be adopted in the occasions where a dual-waveband infrared optical system requires long focal length, large relative aperture and light weight and compactness.
Preferably, the control processor runs camera software, the camera software is internally provided with a plurality of temperature measurement acquisition points, when the far infrared thermal imaging camera is used, the temperature of all the temperature measurement acquisition points is acquired at one time, and the temperature measurement acquisition points and the matched temperature are marked at the corresponding positions of a thermal imaging graph.
Preferably, the control processor runs patrol record management software, and the patrol record management software comprises an input unit, a patrol record database and a patrol record export unit. The patrol record database realizes data archiving in various forms by using the GridFS technology of the MongoDB database and combining the BSON format, and related data is associated by using a complete index technology.

A planar quadrifilar helical circularly polarized antenna is arranged in the RFID reader.
