Description

A kind of monitoring system of tobacco flue-curing house

Technical field

The utility model relates to a kind of monitoring system of tobacco flue-curing house, belongs to the automatic control technology field.

Technical background

Baking is one of most important link of whole leaf tobacco production, and technology content is very high, careless slightly just possibility " being annihilated ".What a lot of most tobacco growers used is earth roasting house, and instrument has only thermometer and hygrometer, and all links are leaned on manually-operated, and risk is very big, in some areas, uses the orange sound tobacco ratio even the less than 10% of earth roasting house.If duration and degree of heating control is bad, in time do not find, will make the tobacco leaf of whole tobacco flue-curing house examine expense so, bring serious economy loss.

Occurred many intelligent tobacco flue-curing houses now, but they there is not temperature and humidity to send to administrative staff with way of short messages, and a prompt functions, the grasp information that the staff can not be promptly and accurately yet.

The utility model content

To above problem, the utility model provides a kind of monitoring system of tobacco flue-curing house, utilize single-chip microcomputer that device is realized accurately control; Can monitor the concrete condition of tobacco flue-curing house automatically, easily, and can in time remind administrative staff with way of short messages, simple in structure, simple to operate, improved the efficiency of management.

The technical scheme that the utility model adopts: system comprises temperature sensor 1, humidity sensor 2, A/D converter 3, single-chip microcomputer 4, IIC module 5, LCD LCD 6 and gsm module 7; Temperature sensor 1 is connected with the input of A/D converter 3 respectively with humidity sensor 2, and the output of A/D converter 3 links to each other with the I/O mouth of single-chip microcomputer 4, and gsm module 7 links to each other with TXD, the RXD mouth of single-chip microcomputer 4, and gsm module 7 links to each other with mobile phone through wireless mode; IIC module 5 links to each other with the I/O of single-chip microcomputer 4 respectively with LCD LCD 6.

Temperature sensor 1 is fixed on the inner different corners of tobacco flue-curing house with humidity sensor 2, and single-chip microcomputer 4, IIC module 5, LCD LCD 6 and gsm module 7 are fixed on the outside of tobacco flue-curing house.

Temperature sensor and humidity sensor are a plurality of.

There is memory function in single-chip microcomputer 4, has solidified one section program code in the single-chip microcomputer in advance.

The beneficial effect of the utility model is: utilize single-chip microcomputer that device is realized accurately control; Can monitor the concrete condition of tobacco flue-curing house automatically, easily, and can in time remind administrative staff with way of short messages, simple in structure, simple to operate, improved the efficiency of management.

Description of drawings

Fig. 1 is the circuit basic composition block diagram of the utility model.

Among the figure: 1-temperature sensor, 2-humidity sensor, 3-A/D converter, 4-single-chip microcomputer, 5-IIC module, 6-LCD LCD, 7-GSM module.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified, understand to make things convenient for the technical staff.

As shown in Figure 1: system comprises temperature sensor 1, humidity sensor 2, A/D converter 3, single-chip microcomputer 4, IIC module 5, LCD LCD 6 and gsm module 7; Temperature sensor 1 is connected with the input of A/D converter 3 respectively with humidity sensor 2, and the output of A/D converter 3 links to each other with the I/O mouth of single-chip microcomputer 4, and gsm module 7 links to each other with mobile phone through wireless mode; IIC module 5 links to each other with the I/O of single-chip microcomputer 4 respectively with LCD LCD 6;

Temperature sensor and humidity sensor are a plurality of; There is memory function in single-chip microcomputer 4, has solidified one section program code in the single-chip microcomputer in advance.

The operation principle of the utility model: administrative staff are according to LCD LCD 6; Through IIC module 5 scope of temperature and humidity, administrative staff's telephone number and the time of sending short messages at definite time are set; Temperature sensor 1 is sensed temperature, humidity with humidity sensor 2; And transmitting signal to A/D converter 3, A/D converter 3 transmits signal again gives single-chip microcomputer 4; Single-chip microcomputer 4 through gsm module, sends to administrative staff to the numerical value of temperature and humidity through handling then.

The course of work of the utility model is:

The first step: energized, this automatic system is started working;

Second step: demonstration " setting " is arranged on the LCD LCD 6; Press " setting " function button on the IIC module 5; Entering is provided with the interface, then according to LCD LCD 6, carries out administrative staff's telephone number setting; The time of sending note is provided with, and can also the temperature and humidity alarm range be provided with; This setting all was effective before being provided with next time.

The 3rd step: be installed in the different corners of tobacco flue-curing house to temperature sensor 1 and humidity sensor 2, the temperature sensor of installation and humidity sensor are a plurality of, but the corner of installation must be targeted.

The 4th step: temperature sensor 1 is transmitting signal constantly with humidity sensor 2 gives A/D converter 3, after handling through A/D converter 3, is transferred to single-chip microcomputer 4 to this signal again;

The 5th step: when temperature that temperature sensor 1 monitors surpass or be lower than be provided with in the temperature of defined, single-chip microcomputer 4 is just given gsm module 7 signals, the temperature of reminding administrative staff's actual temp sensor to monitor exceeds the scope of setting; When temperature that humidity sensor 2 monitors surpass or be lower than be provided with in the humidity of defined, single-chip microcomputer 4 is just given gsm module 7 signals, the humidity of reminding the concrete humidity sensor 2 of administrative staff to monitor exceeds the scope of setting.

The utility model describes through the practical implementation process; Under the situation that does not break away from the utility model scope; Can also carry out various conversion and be equal to replacement utility model; Therefore, the utility model is not limited to disclosed practical implementation process, and should comprise the whole embodiments that fall in the utility model claim scope.
