Description
Technical field
The invention belongs to instrument field, be mainly used in humiture parameter measurement, be specifically related to a kind of to there is the temperature and humidity measurement instrument of debugging functions and a kind of method revising temperature and humidity measurement data.
Background technology
Along with the development in epoch, the industrial sectors such as scientific research, Aero-Space, electric power, the measurement of humiture parameter is got more and more, but the humidity measuring instrument level of domestic and international each producer differs, measuring accuracy do not reach ± and 5%RH is difficult to use as measurement instrument, reach ± the humiture instrument of 2%RH ~ ± 3%RH measuring accuracy is little especially.In actual use, due to the impact of dust, greasy dirt and harmful gas, service time one is long, can produce aging, precise decreasing.Because drift when Temperature Humidity Sensor exists and temperature drift, particularly humidity sensor must contact with the steam in air, can not seal, this just determines its stability and the life-span is limited.Generally, the effective storage life once demarcated is 1 year or 2 years.Currently marketed humiture instrument does not possess the function of correction, after precision can not meet the demands, cannot revise, have a strong impact on result of use.
Summary of the invention
The object of the invention is: provide a kind of and there is the temperature and humidity measurement instrument of debugging functions and a kind of method revising temperature and humidity measurement data, solve the problem that temperature and humidity measurement precision can not be revised.
Technical solution of the present invention provides a kind of temperature and humidity measurement instrument with debugging functions, be made up of Temperature Humidity Sensor 1, single-chip microcomputer 2, storer 3 and display 4, described Temperature Humidity Sensor 1 is for testing environment humiture, and will detect temperature information is sent to single-chip microcomputer 2 in digital form, pre-stored corrected parameter in described storer 3, described single-chip microcomputer 2 transfers the corrected parameter of pre-stored in described storer 3 by calculating the temperature information revised described Temperature Humidity Sensor 1 and send, and shows over the display.
Technical solution of the present invention also provides a kind of method revising temperature and humidity measurement data, uses described measurement instrument, specifically comprises the following steps:
A, Temperature Humidity Sensor 1 testing environment humiture, and will detect temperature information is sent to single-chip microcomputer 2 in digital form;
B, single-chip microcomputer 2 transfers the corrected parameter of pre-stored in described storer 3 by calculating the temperature information revised described Temperature Humidity Sensor 1 and send.
In the method for described correction temperature and humidity measurement data, described in the modified value that prestores measured in advance, comprise temperature corrected value TX and humidity modified value HX1, HX2, HX3, calculating the formula that eyeball humidity modified value adopts is:
(formula a) for HX=(HX2-HX1) × H/20+3HX1-2HX2
HX=(HX3-HX2) × H/20+4HX2-3HX3 (formula b)
Displays temperature value=T+TX
Display humidity value=H+HX
H is actual measurement humidity value, and T is actual measurement temperature value;
In the method for described correction temperature and humidity measurement data, the modified value that the modified value that HX1 is 40%RH, HX2 are 60%RH, HX3 are the modified value of 80%RH.
In the method for described correction temperature and humidity measurement data, H uses formula a at below 60%RH, and H uses formula b at more than 60%RH.
Advantage of the present invention is: thermohygrometer provides modified value after metrological service's calibration, and be set in instrument, the warm and humid angle value of instrument display is corrected warm and humid angle value, measuring accuracy is higher, secondly, calibrate underproof thermohygrometer after revising, as qualified Instrument use, can increase the service life again.
Accompanying drawing explanation
Below accompanying drawing of the present invention is described:
Fig. 1 is instrumentation module schematic diagram of the present invention;
Fig. 2 is the inventive method workflow diagram.
Embodiment
Below in conjunction with Figure of description and embodiment, the present invention is described in further detail.Refer to Figure of description 1 ~ 2.
Hardware of the present invention adopts single-chip microcomputer as microprocessor, adopts the accurate digital relative humidity of the monolithic whole school with I2C bus interface and temperature sensor, has low-power consumption, digital output, exempts from debugging, non-calibrating, feature that consistance is good.Storage chip adopts I2C interface, and circuit is simple, and system is reliable and stable, adopts Liquid Crystal Module as display.
Modification method: the error correction of this instrument is designed to temperature error and is modified to single-point correction, humidity error correction is respectively in 40%RH, 60%RH, 80%RH 3 correction, tried to achieve by linear interpolation at (40%RH to 60%RH) and (60%RH to 80%RH) scope humidity round-off error, tried to achieve by epitaxy at (0 to 40%RH) and (80%RH to 100%RH) scope humidity round-off error.If temperature corrected value is TX, humidity is HX1 in the modified value of 40%RH, is HX2 in the modified value of 60%RH, is HX3 in the modified value of 80%RH, in (40%RH to 60%RH) scope, the modified value HX of humidity H is for shown in formula (a):
(formula a) for HX=(HX2-HX1) × H/20+3HX1-2HX2
