Background technology:
Meter reading instrument is with no paper equipments of recording, is widely used in electric power, chemical industry, and industrial systems such as metallurgy also can be used for power supply to the read-record of traditional industrial monitoring instrument, supply water, and the data of civilian measuring instrument such as air feed are made a copy of.Meter reading instrument and host computer management software are formed the meter reading data management system jointly.Formulate route planning on computers by administrative authority, download on the meter reading instrument again.Check meter the worker according to the path, make a copy of the reading of each instrument successively.To finish then in the database that data in the meter reading instrument that data make a copy of pass back to computing machine and preserve.In the prior art, instrument is provided with electronic tag, electronic tag is made of ROM (read-only memory), solidified unique number numbering when dispatching from the factory, identity sign as instrument, can number be read with the electronic tag readout device, simplify the operation of the route search of checking meter greatly, prevent the path inconsistent phenomenon of fastening one person's story upon another person effectively.Simultaneously, at present the infrared temperature measurement device that adopts can be expanded the purposes of meter reading instrument, can directly measure for the surface temperature of equipment, and need not by special temperature measuring instrument, does not also need the manual data of keying in.But, because electronic tag reader on the meter reading instrument and infrared temperature measurement device all must object-orienteds,, can only be contained in the front end of meter reading instrument side by side for easy to operate, so meter reading instrument laterally will seem very wide, structure is not compact.
Summary of the invention:
The object of the present invention is to provide a kind of electronic tag that is used for the automatic data logging instrument to read and the thermometric combined probe, the described this electronic tag that is used for the automatic data logging instrument reads and the thermometric combined probe will solve prior art electronic tag reader and infrared temperature measurement device is installed in the not compact technical matters of structure that the meter reading instrument front end produces.
This electronic tag that is used for the automatic data logging instrument of the present invention is read with the thermometric combined probe and is made of electronic tag reader and infrared temperature measurement device, described electronic tag reader is by interior electrode, insulation sleeve and external electrode constitute, described infrared temperature measurement device is by shell, thermopile sensor, shadow shield, Infrared Lens, signal conditioning circuit and single-chip microcomputer digital processing circuit constitute, described shell in a tubular form, described thermopile sensor, on shadow shield and the Infrared Lens setting central axis in the enclosure, Infrared Lens is positioned at the inlet end of shell, shadow shield is positioned at the rear side of Infrared Lens, thermopile sensor is positioned at the rear side of shadow shield, thermopile sensor is connected with described signal conditioning circuit by signal conductor, signal conditioning circuit is connected with described single-chip microcomputer digital processing circuit, wherein, described external electrode in a tubular form, electrode in the form of a ring in described, interior electrode is arranged in the external electrode, described insulation sleeve is arranged between interior electrode and the external electrode, interior electrode, insulation sleeve and external electrode are all coaxial with described shell, interior electrode, insulation sleeve and external electrode are arranged on the inlet end of shell, external electrode is connected with shell, the sidewall of interior electrode is provided with lead, and described lead is connected with the single-chip microcomputer digital processing circuit.
Further, the internal diameter of described interior electrode equates with the internal diameter of shell inlet end.
Further, described external electrode is connected with shell by screw thread.
Principle of work of the present invention is: electronic label reader and the coaxial front end that is arranged on meter reading instrument of infrared temperature measurement device, compact conformation.The external diameter of interior electrode is identical with the external diameter of the interior electrode of electronic tag, and when interior electrode contacted with the interior electrode of electronic tag, external electrode contacted with the external electrode of electronic tag, to the electronic tag power supply, reads electronic tag simultaneously.The endoporus of interior electrode becomes the light hurdle at the visual angle of infrared temperature measurement device, that is to say that the infrared luminous energy in angular field of view does not enter temperature probe with not being subjected to loss, and the stray light outside the visual angle just in time is blocked, and infrared temperature measurement device can operate as normal, and thermopile sensor links to each other with signal conditioning circuit.Be provided with a single-chip microcomputer and interlock circuit in the meter reading instrument, electronic tag all links to each other with single-chip microcomputer with the thermoelectric pile sensing element.
The present invention compares with prior art, and its effect is actively with tangible.The present invention makes the meter reading instrument compact conformation with infrared temperature measurement device and the coaxial front end that is arranged on meter reading instrument of electronic tag reader, and volume is little, and outward appearance is succinct.
