Description
Technical field
This utility model relates to a kind of portable high-accuracy data acquisition instrument being applicable to low temperature environment.
Background technology
In frozen soil scientific research cause, ground temperature is as a basic index, and its metering system is from using glass-stem thermometer measurement employing thermistor temperature sensor measurement by now.It may be said that the introducing of critesistor has epoch-making meaning for frozen soil scientific research, it has higher precision and more preferable convenience.Along with deepening continuously of research work, cable for measuring temperature is on the increase, and traditional resistor metering system (circuit tester measurement) can not meet work requirements, thus introduces data acquisition instrument, it is achieved that the automatization of measurement, improves working condition and efficiency greatly.But, the price that data collecting instrument is expensive brings huge pressure to scientific research project, and for the substantial amounts of observation station that early stage is laid, relying on data collecting instrument to realize automation collection needs substantial amounts of financial support, is impossible in a short time.
For there is no the fund of abundance to realize the monitoring project of automatization, continue to use traditional resistor metering system (circuit tester measurement) to be monitored having working environment simultaneously and toil on the feature of inefficiency, it is unfavorable for carrying out of work, it would be highly desirable to seek a kind of instrument and improve work efficiency to improve working environment.Existing Portable acquiring instrument, is affected instrument by low temperature in plateau environment, often occurs the problem such as instrument cisco unity malfunction or certainty of measurement step-down in actual use, and instrument is the heaviest simultaneously.
Summary of the invention
In view of above-mentioned, the purpose of this utility model is to provide a kind of Portable data acquisition instrument being applicable to low temperature environment.This Acquisition Instrument according to actual needs, uses lithium battery group to power, and kit is fixed in protection casing; install insulation material additional to guard box, increase display lamp, reduce the weight of Acquisition Instrument; improve Acquisition Instrument working environment, add the portability of Acquisition Instrument, stability, safety.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of Portable data acquisition instrument being applicable to low temperature environment, is made up of sensor interface, alligator clamp, on and off switch, power supply indicator, measurement display lamp, charging indicator light, charging inlet, guard box, warming plate, data acquisition unit, proprietary extensions plate and lithium battery group.Guard box surface is furnished with sensor interface, crocodile interface, controls switch, power supply indicator, measurement display lamp, charging indicator light and charging inlet, installs warming plate additional, and be equipped with data acquisition unit, proprietary extensions plate and lithium battery group in guard box；Sensor interface is connected with proprietary extensions plate, crocodile interface is connected with alligator clamp, sensor interface is connected with data acquisition unit in measurement display lamp and casing by wire, data acquisition unit is connected with power supply indicator, on and off switch and lithium battery group by wire, and lithium battery group is connected with charging indicator light, charging inlet by wire.
Advantage of the present utility model and providing the benefit that:
1, this utility model uses more frivolous lithium battery group as electric power system, reduces the weight of instrument, alleviates the burden of staff；
The whole series are set and are fixed in protection casing by this utility model, improve portability and safety；
3, this utility model installs insulation material additional to guard box, improves instrumental working conditions and reduces the environment impact on instrument, improves certainty of measurement and stability；
4, this utility model adds display lamp, and user in use can be clearly seen that Instrument working state, it is to avoid because instrument failure or misoperation etc. cause invalid measurement or instrument damage；
5, this utility model is relatively low compared to automatic monitoring cost, just corresponds to traditional measurement cost.There is a set of monitoring instrument each monitoring point of automatic monitoring demand, and cost is the highest, and this utility model reaches the purpose of replacement traditional measurement mode just with a set of self-reacting device by redesign；
6, this utility model has the work efficiency of significantly larger than traditional measurement compared to traditional measurement.In traditional measurement, a monitoring section 4 is gone here and there the cable for measuring temperature nearly 20 minutes time of measurement, and utilizes the semi-automatic monitoring of this utility model to need only to about 5 minutes, is greatly improved monitoring efficiency.
