Description
Technical field
The utility model relates to a kind of thermometric instruments, is a kind of portable automatic temperature measurement instrument specifically.
Background technology
In cryopedology research, temperature survey is one of normal the most measured physical quantity, and the measuring method to temperature and relevant measuring equipment and instrument are a lot, and thermistor temperature detecting is a kind of wherein the most frequently used high precision contact temperature-measuring method.Its temperature-measurement principle is to utilize thermistor (R) in certain temperature range, and its resistance coefficient becomes characteristic accurate, sensitive, regulated linear relation to measure with temperature.
In cryopedology research process, the thermometric field point of monitoring is widely distributed, the probe number that each thermometric field point is monitored is many, this just need to configure a large amount of data acquisition units, and the data acquisition unit overwhelming majority who adopts is at present import equipment, expensive, so many thermometric field points are all by after manually by digital multimeter, regularly (1 time/month, 1 times/year) is measured, then by manually keeping a record.Because field environment is severe, by the temperature sensing means of manually regularly measuring and recording by digital multimeter, not only waste time and energy, and the data personal error of obtaining is often inevitable.Therefore,, in cryopedology research thermometric process, seek simple and feasible, avoid personal error, can be convenient to promote and the measuring equipment that economizes on resources be one must not irrespective problem.
Utility model content
In view of above-mentioned, the purpose of this utility model aims to provide a kind of portable automatic temperature measurement instrument, for storage is measured and recorded to frozen soils temperature automatically.
The purpose of this utility model is achieved through the following technical solutions:
A kind of portable automatic temperature measurement instrument, comprises temp probe, cable, casing, data acquisition unit, expansion board and battery, is provided with data acquisition unit, expansion board and battery in casing; Battery is by electric wire connection data collector; Data acquisition unit connects expansion board; On casing, be covered with air plug, power switch, light emitting diode; Air plug is connected with expansion board by electric wire; Battery is connected in series power switch, resistance, light emitting diode connection data collector by electric wire; Cable is provided with temp probe, is connected with air plug.
In the utility model, data acquisition unit is the core of whole temperature measurer, it has demonstration, communication, the functions such as order control and system detection, expansion board is mainly in order to expand more measurement passage, to can reach the effect of measuring multichannel probe, battery provides working power for temperature measurer system, the on/off of power switch control power circuit, resistance is that light emitting diode plays dividing potential drop effect, light emitting diode be the on/off of power circuit rise indicative function (system power supply circuit connect time be lit, when disconnection, extinguish), air plug has played the effect that convenience connects outside temperature probe.
This temperature measurer is used for field work, utilizing this temperature measurer to carry out before thermometric, needs artificially to write application program to data acquisition unit in advance.In the time that staff arrives a thermometric field point and carries out thermometric, only need the air plug of pegging graft between this temperature measurer and temperature probe, turn on the power switch again, light emitting diode in power circuit is lit, system will automatically be measured and the data that measure are stored in data acquisition unit, and after wait has been measured, staff closes the power switch of this temperature measurer, light emitting diode in power circuit extinguishes, then disconnects the air plug between this temperature measurer and temperature probe.This thermometric field point thermometric completes, and can carry out next thermometric field point and continue thermometric.
The beneficial effect of advantage of the present utility model and generation is:
1, the utility model utilizes data acquisition unit to measure thermometric field point survey temperature probe, artificial with the interference of human factor to measurement data in digital multimeter measuring process before having reduced, and has improved the Stability and veracity of institute's determination data simultaneously.
2, the utility model can arrange any Measuring Time temperature probe is measured, measured data are carried out to the storage of real-time online record simultaneously, accomplish to store robotization, high speed, accuracy and hommization from data acquisition to data, bring into play artificial image data sharpest edges, and increased work efficiency.
3, the utility model is easy to carry about with one, and can be applied to multiple monitoring points, and the data of the multiple monitoring points of fast recording, focus on, and have reduced testing cost.
