Description
Technical field
The utility model belongs to data acquisition system (DAS), is specifically related to a kind of agricultural thing growing environment data acquisition system (DAS).
Background technology
Currently known data acquisition system (DAS) generally all adopts sensor and data acquisition unit simulation connected mode.Less on the degree of difficulty of technical design like this, certain advantage is arranged on the cost of product, but the easy shortcoming such as disturbed of data when existing simultaneously sensor to be difficult for expansion, systematic survey again.At the general nine kinds of needles plug-in unit that adopts of being connected of sensor and collector, this plug-in unit requires height to the manufacture craft of itself, is prone to phenomenons such as loose contact after the repeated multiple times plug.In addition, in the data acquisition system (DAS), main frame adopts common serial communication mode when obtaining the data of data acquisition unit, i.e. the acquisition that do not stop of data acquisition unit is from the analog quantity of sensor, and stores after converting digital quantity to, up to the data buffer is filled up.Therefore its one side communication speed is not enough, and can not satisfy main frame and carry out the data analysis processing, the real-time demand that shows, the data volume of its transmission can not satisfy the needs of main frame abundant data point when drawing the image data image again on the other hand.
The utility model content
The purpose of this utility model is: at the deficiencies in the prior art, provide a kind of good reliability, good stability, highly sensitive, analysis is rapid, rational in infrastructure, anti-interference, performance is good data acquisition system (DAS).
The technical scheme that its technical matters that solves the utility model adopts is: agricultural thing growing environment data acquisition system (DAS), comprise collector, environmental sensor to be measured, the AD data converter, single-chip microcomputer, the wireless data teletransmission, the liquid crystal data display equipment, host computer VB programming controller, storage system and analytic system, it is characterized in that described environmental sensor to be measured be connected with collector and will produce the simulation induced signal change into the digital collection signal by the AD data converter, data are handled and collection being undertaken by single-chip microcomputer, teletransmission is connected communication to single-chip microcomputer with wireless data with the liquid crystal data display equipment, data after handling are sent on the host computer VB programming controller, the data after analyzing are saved in the storage system.Described single-chip microcomputer has channel selecting module, path handover module and switching range module, and described channel selecting module receives from different sensors; Described path selects module by the signal of a range of output under the control of path switch mode enforcement; Described switching range module receives the multirange selection instruction from collector.
The beneficial effects of the utility model: described agricultural thing growing environment data acquisition system (DAS), adopt host computer VB programming software, adopt the modular design design philosophy, design data acquisition system software, frequency acquisition is increased, the error of data reduces, and is not subjected to the interference in external electrical field, magnetic field etc., and has increased the security of self in inflammable, explosive environments.
Description of drawings:
Fig. 1 is structure principle chart of the present utility model.
Fig. 2 is the chip figure of AD824 operational amplifier of the present utility model.
Fig. 3 is software flow pattern of the present utility model.
Embodiment:
In conjunction with Fig. 1, farming thing growing environment data acquisition system (DAS), comprise collector, environmental sensor to be measured, the AD data converter, single-chip microcomputer, the wireless data teletransmission, the liquid crystal data display equipment, host computer VB programming controller, storage system and analytic system, it is characterized in that described environmental sensor to be measured be connected with collector and will produce the simulation induced signal change into the digital collection signal by the AD data converter, data are handled and collection being undertaken by single-chip microcomputer, teletransmission is connected communication to single-chip microcomputer with wireless data with the liquid crystal data display equipment, data after handling are sent on the host computer VB programming controller, the data after analyzing are saved in the storage system.The working environment of described environmental sensor detectable gas to be measured, temperature, humidity and concentration.Described single-chip microcomputer has channel selecting module, path handover module and switching range module, and described channel selecting module receives from different sensors; Described path selects module by the signal of a range of output under the control of path switch mode enforcement; Described switching range module receives the multirange selection instruction from collector.
Detection for some gases, need earlier the signal of gas to be converted to the electric signal of 0-4mV, the acp chip of this signal processing circuit is the AD824 operational amplifier, the operational amplifier of four Performance Match is contained in this amplifier inside, though because the oxygen signal after handling is the signal of 0 ~ 4V, exist the disturbing signal of certain frequency in this signal, influence the measuring accuracy of oxygen content, need carry out filtering and go to disturb processing, this filtering circuit adopts the RC filtering circuit.
In conjunction with Fig. 3, sensor initializing receives data, by 12 A/D converter collections, data are analyzed and handled, if inaccurate will the returning again of image data gathered, if image data accurately is transferred on the LCD and wireless remote transmission, store data and curve plotting figure at last by host computer VB image data again.
