Description
Technical field
The invention belongs to agriculture (sericulture) facilities and equipment field more particularly to a kind of silkworm numeric types with warning function
Hygrothermograph.
Background technique
Temperature and humidity is most important environmental parameter during silkworm feeding, and temperature and humidity energy appropriate is kept in cocoonery
Enough guarantee the healthy growth of silkworm, the quality of ultimate guarantee silk, it is therefore necessary to carry out to the data of the Temperature and Humidity module in cocoonery real
When measure.
It is to use the Hygrothermograph of glass pipe type to the prison of temperature and humidity in cocoonery mostly in existing production method
Survey, but this kind of Hygrothermograph mainly has two big defects: first is that graduated scale is smaller, the silkworm raiser for being not easy to age length carries out temperature and humidity
It reads；Second is that glass tube Hygrothermograph is easily damaged, the heavy metal Hg in glass tube is easily flowed out, and is caused to feeding person and silkworm
Certain harm.
Meanwhile silkworm is during the feeding process, different growth periods, the requirement to temperature and humidity is different, agronomy
It is required that silkworm, in 1~2 age, Acclimation temperature angle value is 26~28 DEG C, humidity is 80~90%RH；3~4 ages, Acclimation temperature
Angle value is 24~26 DEG C, and humidity is 70~80%RH；5 age Acclimation temperature angle value are 23~24 DEG C, and humidity is 65~70%
RH；Accurately Temperature and Humidity Control is more advantageous to the growth of silkworm.
Patent CN208187468U discloses a kind of dual-purpose Hygrothermograph of life sericulture, and the device is with glass pipe type thermometer
For measuring device, the temperature and humidity fitness value of different silkworm ages is labelled in temperature and graduation mark, specific aim is stronger, but when warm and humid
When degree is beyond the fitness value set, no prior-warning device cannot issue the user with early warning.
To sum up, in order to realize the real-time measurement to temperature and humidity in cocoonery and be read convenient for user, while in data of the Temperature and Humidity module
Early warning is issued the user with when abnormal, it is necessary to carry out the research of the numeric type silkworm Hygrothermograph with warning function.
Summary of the invention
It is an object of the invention to solve above-mentioned prior art defect, a kind of silkworm numeric type with warning function is provided
Hygrothermograph is realized and is shown to the real-time measurement of temperature and humidity in cocoonery and digitlization, and exceeds the adaptation of setting in measurement data
When angle value, early warning is issued the user with, takes necessary measure, avoids unnecessary economic loss.
The present invention adopts the following technical scheme that in order to realize the above technical effect:
A kind of numeric type Hygrothermograph of the silkworm with warning function specifically includes that single-chip minimum system module, 4 independences
Key module, LCD12864 LCD MODULE, DHT11 temperature humidity sensor module and warning module.
Further, the single-chip minimum system uses STC89C51 for Master control chip；4 independent keys are silkworm
Phase selecting unit after powering on or resetting, presses different keys and represents the different silkworm rearing season measurement of progress, system will set corresponding
Fitness value.Wherein: when Button1 is pressed, representing current silkworm rearing season as 1~2 age silkworm, the Acclimation temperature angle value of default is
26~28 DEG C, humidity is 80~90%RH；When Button2 is pressed, current silkworm rearing season is represented as 3~4 age silkworms, default temperature
The fitness value of degree is 24~26 DEG C, and humidity is 70~80%RH；When Button3 is pressed, current silkworm rearing season is represented as 5 age silkworms,
The Acclimation temperature angle value of default is 23~24 DEG C, and humidity is 65~70%RH.
Further, a kind of silkworm with warning function is by DHT11 sensor with numeric type Hygrothermograph
Module carries out the acquisition of temperature and humidity simultaneously.
Further, the warning module is made of buzzer and red light emitting diodes, when DHT11 sensor module
After measuring current temperature and humidity data, measurement data is compared by system with the fitness value of setting automatically, if
Measurement data exceeds fitness value, will start prewarning unit, is flashed by buzzer call and red light emitting diodes to user
Early warning, warning user take necessary measure.
Further, a kind of silkworm with warning function can be also used for daily survey with numeric type Hygrothermograph
It measures, after system reset, presses Button4 and then carry out general measure, will be set without silkworm rearing season and fitness value, only by measurement
Data of the Temperature and Humidity module carries out digitlization and shows.
Further, a kind of numeric type Hygrothermograph of the silkworm with warning function, mode of operation is system
After powering on, Display of Chinese characters character " please select silkworm rearing season " on LCD12864 LCD MODULE, user is according to current silkworm at this time
Growth actual conditions press corresponding key, then automatically into the measurement of data of the Temperature and Humidity module, when the data measured exceed system
When the fitness value of setting, system starts warning function.
Further, a kind of numeric type Hygrothermograph of the silkworm with warning function, digitlization display are main
Have: in system electrification/reset, the second row, which is shown, on LCD12864 Liquid Crystal Module " please select silkworm rearing season！"；It is measuring
When, the first row shows fixed character string " silkworm Hygrothermograph " on LCD12864 Liquid Crystal Module, shows current institute in the second row
The silkworm rearing season at place, display format are fixed character " silkworm rearing season: "+" one, two ages " or " three, four ages " or " five ages ".If it is conventional survey
Amount mode then shows character string " daily measurement " that the third line shows that fixed character string " Current Temperatures: " Dynamically Announce is surveyed behind
The temperature measured+DEG C, fourth line shows fixed character string " current humidity ", the humidity+% that Dynamically Announce measures behind, from
And it realizes the digitlization of data of the Temperature and Humidity module and shows.
Compared with existing Hygrothermograph, the beneficial effects of the present invention are:
(1) present invention is that the Hygrothermograph being mainly used in during breeding silkworms selects different silkworm rearing seasons according to silkworm growth cycle
Measurement, system sets corresponding fitness value automatically, at the same time it can also the general measure for daily life.
(2) result of the invention by measurement is more existing using Chinese character and number as basic display elements by digitized form
Some glass tube Hygrothermographs are compared, and it is more convenient easy to read data.
(3) the maximum feature of the present invention be with warning function, when measuring temperature and humidity and exceeding the agriculture requirement of silkworm rearing season,
By buzzer call, red light emitting diodes flash caution user takes necessary measure, avoids economic loss.
(4) it due to using DHT11 sensor module for measuring unit of the invention, avoids glass thermometer and may be crushed and make
At glass dregs harm, mercury endangers the problem of the health of raiser and silkworm, realizes mercuryless measurement.
