An STM32 series single-chip microcomputer is adopted as the single-chip microcomputer, and the model is STM32F215VGT6; a psychrometer which comprises DS18B20 is selected as the temperature and humidity sensor; and SIM900A is adopted as the GPRS module. The barn temperature and humidity remote monitoring system based on the GPRS technology and an intensive barn controller share the temperature and humidity sensor, and the normal work and the baking process of existing equipment are not affected; and temperature and humidity during a baking process are sent back to an upper computer remotely, real-time display and history inquiry are realized in a database, and the system has greater significance in analyzing the baking technology of tobacco grower, improving the baking level and thus improving the tobacco leaf baking quality.
Description
Technical field
The utility model relates to the IT application to agriculture field, particularly relates to a kind of barn humiture remote supervision system based on the GPRS technology.
Background technology
The bulk curing barn controller is widely used in the tobacco flue-curing at home at present, it is by gathering the humiture value of barn, automatically judge the baking state,, thereby obtain tobacco flue-curing effect preferably by program and peripheral blower fan, electric controlled door and the fan blower of artificial setup parameter control.This instrument has the following disadvantages:
1, the humiture data of bake process can only be connected on the instrument by the download line and obtain, and can't obtain by remote auto;
2, the display module on the instrument is the LED charactron, can't show the baking curve.
Because there is above defective in this instrument, humiture data valuable in the tobacco flue-curing process can not get effective utilization, and tobacco grower's flue-cured tobacco technology can only obtain judging, can't analyze data, improve the standard from the baking curve by checking and accepting tobacco leaf.
Therefore develop a kind of barn humiture remote supervision system based on wireless transmission, compatible existing bulk curing barn controller of while, not influencing baking process is a kind of selection preferably.Still there is not the correlative study report at present.
The utility model content
Problem in view of above prior art exists the object of the present invention is to provide a kind of barn humiture remote supervision system based on the GPRS technology.
A kind of barn humiture remote supervision system based on the GPRS technology comprises: single-chip microcomputer and the Temperature Humidity Sensor that is connected with single-chip microcomputer, GPRS module, radio-frequency card identification module, charactron display module.Described single-chip microcomputer adopts the STM32 series monolithic, and model is STM32F215VGT6; Described Temperature Humidity Sensor is selected the wet-and-dry bulb thermometer with the DS18B20 composition; Described GPRS module is selected SIM900A; Described radio-frequency card identification module is selected the read-write process chip MFRC530 of Mifare card special use for use.
Based on the barn humiture remote supervision system and the shared Temperature Humidity Sensor of bulk curing barn controller of GPRS technology, do not influence the operate as normal and the baking process of existing equipment; With the long-range host computer that sends it back of the humiture of bake process, in database, show in real time and historical query, to analyzing tobacco grower's baking technology, improve the baking level, thereby improve baking quality of tobacco big meaning is arranged.
Description of drawings
Fig. 1 is a barn humiture remote supervision system hardware structure diagram;
Embodiment
Below in conjunction with specific embodiment, the utility model is elaborated.
With reference to figure 1, comprise based on the barn humiture remote supervision system of GPRS technology: single-chip microcomputer and the Temperature Humidity Sensor that is connected with single-chip microcomputer, GPRS module, radio-frequency card identification module, charactron display module; The temperature-humidity signal that Temperature Humidity Sensor obtains inserts single-chip microcomputer earlier, and temperature-humidity signal outputs on the bulk curing barn controller from single-chip microcomputer again; The function of radio-frequency card identification module is the content of discerning and reading radio-frequency card; The charactron display module shows the parameters such as content, system state and humiture of radio-frequency card; The function of GPRS module is that remote datas such as radio-frequency card content and humiture are sent it back host computer.The humiture data of Temperature Humidity Sensor collection are introduced into barn humiture remote supervision system, by this system with radio-frequency card content and temperature-humidity signal by the long-range host computer that sends it back of GPRS module, temperature-humidity signal is come out from barn humiture remote supervision system more then, enters the bulk curing barn controller.
Single-chip microcomputer can be 51 single-chip microcomputers, PIC single-chip microcomputer etc., and the effect of external radio-frequency card identification module is an identification tobacco grower IC-card, reads contract number; The effect of charactron display module is to show parameters such as contract number, real-time humiture value and system state; The effect of GPRS wireless module is to give host computer with humiture value and contract number remote transmission, handles in database; The Temperature Humidity Sensor shared with the bulk curing barn controller can be digital transducers such as DS18B20; Storage chip can be with the humiture data storage in system.
Adopt the STM32 series monolithic, model is STM32F215VGT6, and Embedded Operating System adopts the uc/OS real-time multi-task operating system; Temperature Humidity Sensor is selected the wet-and-dry bulb thermometer with the DS18B20 composition; The GPRS wireless module is selected SIM900A; The radio-frequency card identification module is selected the read-write process chip MFRC530 of Mifare card special use for use; Storage chip adopts magnificent nation storer, and model is 25Q16.
At first, wet-and-dry bulb thermometer (based on digital temperature sensor DS18B20) transmits the temperature-humidity signal in the barn return, for fear of the phase mutual interference, native system reads level on the bus by the single-chip processor i/o mouth, when detecting rising edge or negative edge, just know that the bulk curing barn controller is reading the humiture data, therefore this instrument is delayed 200 milliseconds and is read the humiture data, thereby the data of avoiding reading Temperature Humidity Sensor simultaneously with the bulk curing barn controller cause data perturbation.
After collecting the humiture data, this instrument with the humiture data presentation on charactron, while and contract number packing instrument send it back host computer by the GPRS wireless module and handle, when new user begins flue-cured tobacco, read tobacco grower's IC-card number by the radio-frequency card identification module, thereby judge the user's that makes new advances identity.
Should be understood that, for those of ordinary skills, can be improved according to the above description or conversion, and all these improvement and conversion all should belong to the protection domain of the utility model claims.
