Description
Technical field
The invention belongs to automation control area, particularly relate to a kind of for quality automatic measurement system in climatic chamber.
Background technology
Before building materials fire protection, combustibility test, test specimen the statutory standards corresponding to this test need carry out status adjustment (temperature, humidity), makes the representative and reappearance of test.Existing its duty of adopted measuring method: adopt constant temperature humidity chamber, electronic balance, crystal clock, staff needs repeatedly from taking-up electronic balance weighing in constant temperature humidity chamber to often kind of sample in the process regulated, time then carrys out artificial timing by crystal clock, and personal error is larger; After each weighing, related personnel needs to carry out arrangement to data and calculates, and person works measures greatly; Corresponding personnel need weigh sample on time, increase person works's amount.Because of above-mentioned reason, newly together need regulate in the time of specifying and other samples to sample, can not regulate at any time, regulate efficiency extremely low.
Summary of the invention
Technical matters to be solved by this invention is that providing a kind of is intended to for quality automatic measurement system in climatic chamber the automatic measurement realizing sample, reduces the error of manual measurement.
The present invention is achieved in that a kind of for quality automatic measurement system in climatic chamber, and in climatic chamber, arrange multiple sample carrier, be provided with force cell in each sample carrier, this system comprises:
Control module, control module connection arranges module, by arranging module installation desired treatment temp and process humidity;
Data acquisition module, the input end of described data acquisition module is connected with multiple force cell, and calibration is initialization force cell also, and the instruction according to control module gathers force cell and data are passed to control module;
In the holder of control module judgement sample, whether the initial mass of force cell measurement sample is greater than zero, and start timing by built-in clock, initial mass is the sample not record of zero, and the force cell Measurement channel of correspondence is closed, there is the sample record initial mass of initial mass and be labeled as M
t0, after measurement, close corresponding force cell;
Control module sends measurement instruction every 1h to data acquisition module, and the Measurement channel opening force cell carries out measurement quality, and the time of repetitive measurement is stored in storer with corresponding measurement quality by control module;
Computing module, computing module transfers the measurement data in storer in real time, and the data being greater than 24 hours the time judge according to the following formula: judge
whether set up, in formula, △ m represents that the time is greater than certain moment T(h of 24 hours) sample quality and T-24 hour before the ropy absolute value of sample quality in certain moment t (h) any, n represents the mistiming between moment T (h) and moment t (h), m (t) represent T-24 hour before the sample quality in certain moment t (h) any, unit is g;
As moment T(h) sample quality and T-24 hour before certain moment t (h) any sample quality ropy absolute value meet
time, computing module sends information to control module, and control module closes the Measurement channel of corresponding force cell by data acquisition module;
Display and alarm module, after force cell complete for measurement numbering is passed to display and alarm module by control module, display is carried out showing corresponding force cell with alarm module and is numbered and give the alarm.
Further, when
when being false, control module continues through the quality signal of data collecting module collected force cell.
Arrange the thermostatic constant wet chamber that multilayer independently controls in this climatic chamber, each constant temperature and humidity indoor arrange multiple sample carrier, are provided with force cell in each sample carrier.
Compared with prior art, beneficial effect is in the present invention:
Sample no longer takes out after putting into test, (repeatedly taking out weighing) impact on regulating effect of cutting down the number of intermediate links.Can regulate in time after sample, increase work efficiency, the very first time can point out adjustment to complete, and has saved the time detected.Adjustment process controls automatically, alarm and display, and each sample adjustment state is very clear, easy to operate.
Sample can be put into constant temperature and humidity indoor at any time and regulate, and does not affect the adjustment of the indoor sample of other constant temperature and humidities.
Accompanying drawing explanation
Fig. 1 is the module frame chart that the embodiment of the present invention provides.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, a kind of for quality automatic measurement system in climatic chamber, for measuring under constant temperature and humidity condition, under the temperature and humidity condition of setting, sample quality reaches constant, multiple sample carrier is set in climatic chamber, force cell is provided with in each sample carrier, the climatic chamber adopted is constant temperature and humidity box structure conventional on the market, this system comprises control module, data acquisition module, control module, computing module and display and alarm module: data acquisition module is connected force cell, the simulating signal gathered by force cell is converted into digital signal transfers to control module, control module connection arranges module, by arranging module installation sample processing time, desired treatment temp, process humidity, the input end of data acquisition module is connected with multiple force cell, calibration initialization force cell, gathers force cell and be that digital signal transfers is to control module by data transformations according to the instruction of control module.
In the holder of control module judgement sample, whether the initial mass of force cell measurement sample is greater than zero, and start timing by built-in timing module, initial mass is the sample not record of zero, and the force cell Measurement channel of correspondence is closed, there is the sample record initial mass of initial mass and be labeled as M
t0, close corresponding force cell after measurement, control module sends measurement instruction every 1h to data acquisition module, and the Measurement channel opening the non-vanishing force cell of initial mass carries out measurement quality, repetitive measurement time and measurement quality store by control module, control module sends instruction to computing module simultaneously, computing module transfers up-to-date data in real time, up-to-date measurement quality is labeled as m (T), the measurement quality being greater than 24 hours of up-to-date Measuring Time is labeled as m (t), judges according to the following formula: judge
whether set up, in formula, △ m represents that the time is greater than certain moment T(h of 24 hours) sample quality m (T) and T-24 hour before the ropy absolute value of sample quality m (t) in certain moment t (h) any, n represents the mistiming between moment T (h) and moment t (h), mistiming is minimum is 24 hours, m (t) represent T-24 hour before the sample quality in certain moment t (h) any, unit is g, during calculating, certain moment T(h that time is greater than 24 hours) respectively and be that interval data of 1 hour zero compare judgement from initial time, as long as detect sometime
then computing module stops the calculating of corresponding sensor and sends information to control module, and control module closes the Measurement channel of corresponding force cell by data acquisition module, after force cell complete for measurement numbering is passed to display and alarm module by control module, display is carried out showing corresponding force cell with alarm module and is numbered and give the alarm.
Also can arrange the time starting computing module and start to calculate in the present invention, such as, be arranged to 48 hours, when sample processing time reaches 48 constantly little, computing module starts to carry out judgements calculating.
