Description
Technical field
The utility model relates to field of temperature measurement, and in particular to a kind of parallel multi-point thermo detector.
Background technique
Temperature measurement is to make quantitative measurement with temperature of the temperature measuring device to object.Warm physical quantity estimates measurement actually
It is a certain amount to the object, which should make the relatively aobvious of dullness in certain temperature range with the variation of object temperature
The variation of work.Wherein electricity thermometry uses mark of certain electrical quantities varied with temperature as temperature, belongs to this kind
Thermometer mainly has thermocouple thermometer, resistance thermometer and semiconductor thermistor thermometer.
Current temperature measurers many on the market all can only carry out temperature test for single-point, and hand-kept temperature is needed to become
Change value.In actual operation, many occasions need while testing the temperature of multiple points, and require to draw temperature history curve
When, to facilitate carry out Statistical Comparison.Market temperature measurer on sale is all generally single-point thermometric at present, and manual record is needed to go through
History data, low efficiency and easy error.
Utility model content
In view of the deficiencies of the prior art, the utility model provides a kind of parallel multi-point thermo detector, greatly convenient to tested
The monitoring and analysis of temperature spot.
In order to achieve the above object, the utility model is achieved by the following technical programs: a kind of parallel multi-point thermo detector,
Including microprocessing unit, a GPIO pin of the microprocessing unit is connected to the data-interface of several temperature sensors,
The VCC pin and GND pin of the temperature sensor are unified to be grounded, and the microprocessing unit reads each temperature by circulation
Sensor obtains real-time temperature values, the microprocessing unit host is connected to by serial ports and send this circle collection to
Temperature value.
Preferably, the model DS18B20 of the temperature sensor.
Preferably, the microprocessing unit is connected to host by RS232 serial ports.
Preferably, the quantity of the temperature sensor is up to 64.
The utility model provides a kind of parallel multi-point thermo detector, and operation is as follows: the present apparatus after the power-up, micro process
Unit begins through the real-time temperature values that forms data line interface circulation reads each temperature sensor；Microprocessing unit is according to host
Order uploads the real time temperature data of each temperature sensor by serial ports；Temperature data is handled and is saved by host；This
The protection point of tester is to utilize microprocessing unit real-time monitoring, parallel multi-spot temperature testing sensor multiple spot real-time testing temperature
Data carry out data processing in conjunction with host and save.
