Abstract
A digital temperature sensor of a temperature measuring device of a heat exchanger of a sewage source heat pump connects with a serial port of an AT89S52 single-chip microprocessor. The AT89S52 single-chip microprocessor connects with a display screen. The AT89S52 single-chip microprocessor also connects with industrial grade digital transmission and converting interface M-BUS. The temperature measuring device of the heat exchanger of the sewage source heat pump is a temperature measuring system of the heat exchanger of the sewage source heat pump. The length configuration of temperature compensation lines of each sensor does not need to calculate and no adjustment is needed. The temperature measuring device of the heat exchanger of the sewage source heat pump in the utility model is in a plug-and-play type. By using the temperature measuring device of the heat exchanger of the sewage source heat pump in the utility model, data can be transmitted in a long range and the system configuration cost is low.
Description
Technical field
The utility model belongs to sensing technology temperature survey field, particularly a kind of sewage source heat pump heat exchange temperature measurement mechanism.
Background technology
Sewage source heat pump work under hot and humid environment for a long time at present, therefore the sewage source heat pump power consumption is big needs thermovent, and such device is worked under above-mentioned environment and is easy to take place permanent failure.For the very first time is detected and the technical maintenance service sewage source heat pump, the sewage source heat pump service data monitoring remote collection device that existing sewage source heat pump is installed.Raw sewage source heat pump heat exchange temperature measuring 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 utility model provides a kind of sewage source heat pump heat exchange temperature measurement mechanism, and cost is low reliable.
The utility model content is:
The utility model: a kind of sewage source heat pump heat exchange temperature measurement mechanism; Adopt the principle of sensing on little silicon wafer; And the serial ports that connects AT89S52 single-chip microcomputer (2) with the chip of Direct Digital temperature value output as digital temperature sensor (1); AT89S52 single-chip microcomputer (2) connects display screen (3), and AT89S52 single-chip microcomputer (2) also connects technical grade digital transmission translation interface M-BUS (4).
Measuring process is: move the thermometric start-up routine to (1) by AT89S552 single-chip microcomputer (2); (1) carries out the thermometric order; And the Temperature numerical of measuring is sent to AT89S552 single-chip microcomputer (2); AT89S552 single-chip microcomputer (2) is sent to display screen (3) with the Temperature numerical of measuring and shows this numerical value; AT89S552 single-chip microcomputer (2) is sent to technical grade digital transmission translation interface M-BUS (4) with the Temperature numerical of measuring, and technical grade digital transmission translation interface M-BUS (4) is responsible for measurement data is sent to the remote data center.
The characteristics of this institute utility model are:
This device is a sewage source heat pump heat exchange temperature measuring 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.
