Abstract
Provided is a stratigraphic temperature fine measurement recording apparatus for a thermal response system, which employs a direct digital temperature value output chip, an interface M-BUS of which is in connection with an AT89S52 one-chip microcomputer; the AT89S52 one-chip microcomputer is in connection with an industrial control PC, wherein a data transmission line is a common copper lead. The advantages of the utility model lie in that calculation of temperature compensating wire length calculation of each sensor is not needed; debugging is not needed; the apparatus is plug-and-play and has the advantages of long data transmission and low costs of a composition system.
Description
Technical field:
The utility model belongs to field of sensing technologies, specifically relates to the warm layer by layer meticulous survey record device in ground of a kind of thermal response system.
Background technology:
Traditional temperature measurement system is because of adopting PT100; PT1000 resistance-type temperature-measurement principle, the distance of carrying with transducing signal is different, must calculate the temperature compensation line length configuration of each sensor; Bring very big inconvenience for Installation and Debugging and data transmission, it is high to form system cost.
The utility model content
The purpose of the utility model provides the warm layer by layer meticulous survey record device in ground of a kind of thermal response system.The use that solves original measurement mechanism is inconvenient, the problem that cost is high.
The particular content of the utility model is:
The warm layer by layer meticulous survey record device in ground of a kind of thermal response system; It is characterized in that: this device adopts the chip (1) of the Direct Digital temperature value output of little silicon wafer; The chip interface M-BUS of its Direct Digital temperature value output connects AT89S52 single-chip microcomputer (2); AT89S52 single-chip microcomputer (2) connects industry control PC (3), and wherein data line is the ordinary copper lead.
Measuring process is: by the chip of AT89S552 operation thermometric start-up routine to the Direct Digital temperature value output of little silicon wafer; The chip of the Direct Digital temperature value output of little silicon wafer is carried out the thermometric order; And the Temperature numerical of measuring is sent to the AT89S52 single-chip microcomputer, the AT89S52 single-chip microcomputer is sent to industrial computer with the Temperature numerical of measuring and shows this numerical value and set up the warm database of layer.Data line is the ordinary copper lead.
The utility model has the advantages that the warm layer by layer meticulous survey record device in ground of this thermal response system, need not calculate the temperature compensation line length configuration of each sensor, need not debug, plug and play, data transmission is far away, and it is low to form system cost.
