Description

The shell temperature measurement mechanism that many people use simultaneously

Affiliated technical field

The utility model relates to the shell temperature measurement mechanism that a kind of many people use simultaneously, also is applicable to the temperature survey in a plurality of places, place such as industry spot, agriculture green house of vegetables, belongs to the electronic instrument technical field.

Background technology

At present, what measurement of bldy temperature adopted in most of hospital is, utilize the mode of the artificial Timing measurement of mercury thermometer, this routine care not only expends a large amount of manpowers, measurement result is gathered, is inquired about, is analyzed all more numerous and diverse, and can feel inconvenient when reading measurement result, read untrue even.It is therefore, at present this that manually to look into the traditional approach of surveying body temperature to be improved.

While utilizing mercury thermometer to measure human body temperature; can only be measured a people at one time, can not be carried out measurement of bldy temperature to a plurality of people simultaneously, and in reality; measure the situation of a plurality of places temperature as places such as industry spot, agriculture green house of vegetables simultaneously, often can run into.

Summary of the invention

The purpose of this utility model is, designs the shell temperature measurement mechanism that a kind of simple in structure, easy to operate many people use simultaneously.Except can carry out the shell temperature measurement for many people simultaneously, the temperature survey for a plurality of places, place such as industry spot, agriculture green house of vegetables, home poultry raising place, Meteorological geotemperatures, all have practicality preferably.Temperature measurement range is-55 ℃～+ 125 ℃, 0.0625 ℃ of thermometric resolution.

For achieving the above object, the technical solution of the utility model is: the shell temperature measurement mechanism that many people use simultaneously, comprise the temperature sensor network (1), microcontroller (2) with display (3), (2) (1) the temperature sensor network be connected with microcontroller, (3) (2) microcontroller be connected to display.

(3) described display consists of 240 * 128 dot matrix lcd module LCM240128, at microcontroller under control (2), and the digitizing Presentation Function of completion system status information and temperature value.

(2) described microcontroller forms minimal application system by integrated circuit (IC) chip AT89C55, is the control center of native system, realizes to the temperature sensor network control and real time temperature measurement (1), and controls display demonstration work (3).

(1) described temperature sensor network is comprised of a plurality of digital temperature sensor DS18B20 chips based on unibus (1-wire) technology.

Described unibus (1-wire) is connected to the P3.3 pin of microcontroller AT89C55 chip, pin thus, AT89C55 receives from the temperature sensor network shell temperature metrical information (1), microcontroller AT89C55 is under the control of application program, after metrical information is processed, the shell temperature value is delivered to 240 * 128 dot matrix lcd module LCM240128, with digital formal intuition show.

The beneficial effects of the utility model are: the shell temperature measurement mechanism that these many people use simultaneously is simple in structure, and operation is very easy; Owing to adopting unibus (1-wire) technology, so be easy to the temperature measuring point quantity in the extended temperature sensor network; Except can carry out, the shell temperature measurement, also being applicable to the temperature survey in a plurality of places, place such as industry spot, agriculture green house of vegetables, Meteorological geotemperature for many people simultaneously, there is actual application prospect preferably.
