Description
Technical field
The utility model relates to a kind of sensor that is used for the monitoring mine environment temperature.
Background technology
Temperature pick up is primarily aimed at mine to be had the environment for use of explosion gas and designs, and is used for the testing environment temperature, can be used in manufacturing monitoring system or the environmental monitoring system acquisition terminal as temperature data.The general measure error of existing temperature pick up is bigger, and inconvenient installation.
Summary of the invention
The purpose of the utility model provides a kind of measure error temperature pick up little and easy for installation.
In order to achieve the above object, the technical scheme of the utility model has provided a kind of temperature pick up, it is characterized in that: comprise temperature-sensing element (device); Temperature-sensing element (device) connects the temperature transmission circuit; The temperature transmission circuit links to each other with the A/D change-over circuit, and the A/D change-over circuit connects microprocessor, and microprocessor also connects power circuit, memory cell, signal output apparatus, display unit and operating unit; Wherein, signal output apparatus connects external equipment through aviation plug.
Preferably, said temperature-sensing element (device) is the PT100 thermal resistance.
Preferably, said operating unit is the IR receiving circuit.
Characteristics such as the utlity model has that range is wide, measure error is little and low in energy consumption, and, the aviation plug wiring adopted, the convenient installation.
Description of drawings
The circuit block diagram of a kind of temperature pick up that Fig. 1 provides for the utility model.
The specific embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 1, a kind of temperature pick up for the utility model provides comprises temperature-sensing element (device), and in the present embodiment, temperature-sensing element (device) adopts the PT100 thermal resistance.Temperature-sensing element (device) connects the temperature transmission circuit; The temperature transmission circuit links to each other with the A/D change-over circuit; The A/D change-over circuit connects microprocessor (English abbreviates MCU as), and microprocessor also connects power circuit, memory cell, signal output apparatus, display unit and operating unit.In the present embodiment, memory cell is EEPROM, and wherein, signal output apparatus connects external equipment through aviation plug.
12～18VDC supply voltage of power supply input is converted into+supply voltage of 5VDC by power circuit, supply with other circuit units.The PT100 thermal resistance converts temperature signal into resistance signal; Converting resistance signal into voltage signal by the temperature transmission circuit again; Voltage signal is given MCU after sampling through the A/D change-over circuit, after MCU handles, shows that by display unit display unit is made up of 4 charactrons.Simultaneously, signal output apparatus is according to the corresponding with it frequency signal of temperature value output that collects.In addition, what EEPROM was used for storage sensor is provided with parameter and other descriptors, and operations such as an IR receiving circuit is used for sensor as operating unit adjustment and demarcation are provided.
