Abstract
The invention discloses an uncompensated digital temperature measurement system, comprising a chip, namely a digital temperature sensor capable of directly outputting a digital temperature value, wherein the serial port of the digital temperature sensor is connected with a singlechip AT89S52, and the singlechip AT89S52 is connected with a display screen; and the singlechip AT89S52 is also connected with an industrial grade digital transmission conversion interface M-BUS. The invention has the advantages that the device is an advanced industrial grade temperature measurement system, the temperature compensated line length configuration of each sensor is not required to be calculated, the debugging is not required, the plug and play effect can be realized, the digital transmission is far, and the cost of the system composition is low, and the invention is particularly applicable to a temperature measurement system constituting terrestrial heat course monitoring.
Description
Technical field
The invention belongs to temperature measuring equipment, particularly a kind of non-compensating digits temperature measurement system.
Background technology
The technical grade 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, form the system cost height.
Summary of the invention
Technical matters to be solved by this invention is: a kind of non-compensating digits temperature measurement system is provided.
Technical scheme of the present invention is:
A kind of non-compensating digits temperature measurement system is characterized in that: the chip of Direct Digital temperature value output--its serial ports of temperature digital sensing [1] connects AT89S52 single-chip microcomputer [2], and AT89S52 single-chip microcomputer [2] connects display screen [3]; AT89S52 single-chip microcomputer [2] also connects technical grade digital transmission translation interface M-BUS[4].
Effect of the present invention is:
This device is an advanced technical grade temperature measurement system, need not calculate the temperature compensation line length configuration of each sensor, need not debug, and plug and play, data transmission is far away, and it is low to form system cost.Be specially adapted to constitute the temperature measurement system of underground heat process monitoring.
Description of drawings
Fig. 1 is the structural representation of non-compensating digits temperature measurement system
Embodiment
