The work process of the present invention: when using preserving jar, first, open the cover 9 of preserving jar, cover 9 plugs in or loads onto battery, turn on the power switch S, MCU control circuit initializes, then PD1 mouth output high level, the energising preheating of AQM-300E air quality module, PD0 exports high level, by the MCU address choice memory module 24C02 sent, read natural law and the air quality value of storage, afterwards by the MCU address choice TH02 Temperature and Humidity module sent, input the corresponding command carries out temperature, Humidity Detection, and the temperature after reading and converting, humidity value.PB6 mouth output high level, lighting LCD backlight lamp, MCU control circuit sends the read write command to lcd driver HT1621, by Item Number, current temperature, humidity, air quality value and storage natural law are shown on LCD, and air quality value is shown as the value of detection last time.At this moment, by control panel 3, pressing ' ADD ' key, select to be shown as the article storage numbering in '--' room, place an article within the corresponding numbered positions of storing tank body 8, then press START key and add their confirmation, such MCU will start timing, while LCD display natural law 00.Then, cover preserving jar cover 9, pull the compression button 902 on cover 9 with hands, the flange 801 compressed on button 902 alignment tank body 8 is buckled.Then, after reaching program setting preheating time, read air quality value, shown by LCD, when air quality is normal, be shown as ' 0 '；When air quality mile abnormality, it is shown as ' 1 '；When air quality moderate exception, it is shown as ' 2 '；When air quality severe exception, it is shown as ' 3 '.If during by air quality severe exception, the state of ' 3 ' of being shown as is set as being sent to the state of client, then when control circuit obtains air quality severe extremely, when being shown as the state of ' 3 ', the PA4 mouth output high level of MCU, start wireless communication module 5, MCU through RX, TX, PC2 PC4 mouth, by WSUM102A module, the air quality of detection, humiture data are sent to client terminal.The acquiescence article code powered on is 01, and the storage natural law of display is the storage natural law of article code 01.If the Item Number of display does not store article, the natural law that LCD shows is '--', represents that this storage place is for sky.
Subsequently into holding state, wait button operation, if pressing ADD increases key, often pressing once, Item Number order adds 1, and Item Number changes between 1～99～1, namely when Item Number is maximum 99, then press this key Item Number and then show again 1, so circulate.Along with the change of Item Number, corresponding article storage natural law also can show according to the change of Item Number successively.If LCD shows '--', represent that this bit of storage does not have article, for room.
If desired during storage article, by pressing ADD key, after selecting the storage numbering in display room, putting down the article of storage on this room, then press START key and add their confirmation, such MCU will start timing, the natural law 00 of LCD display simultaneously.
When if desired taking out the article of certain numbering position, by pressing ADD key, choose after article of certain storage numbering position take out, press CLEAR key, remove the information such as storage natural law of this Item Number, simultaneously LCD display natural law '--'.
Air detection module AQM-300E is after the time preheating set, and MCU reads AQM-300E Detection of Air Quality data.And the data of detection are stored in 24C02.And make PD1 mouth output low level, close air detection module, to reduce power consumption.
If pressing SEND key, then PA4 mouth output high level, communication module WSUM102A starts working, the Item Number that display 4 is shown by MCU by this module, corresponding article storage natural law, temperature, humidity and air detection data are sent to client terminal, to realize and mobile phone or remote computer communication.After having sent data, PA4 mouth output low level, communication close module, reduces power consumption.
When there is no button operation within the time exceeding program setting, make PD0 mouth, PB6 mouth output low level, close LCD show, 24C02 memory module, TH02 Temperature and Humidity module and AQM-300E air quality module 2 power supply, to reduce power consumption.MCU enters park mode simultaneously, to reduce power consumption.
Under MCU park mode, there are two kinds of wake-up modes:
One, overflowed by timer internal and wake MCU up, as time counting, if program determines 24 hours, storage natural law is added 1, and it is stored in memory chip, when after the time natural law reaching program setting, open TH02 Temperature and Humidity module 1, the detected value of read module, and open AQM-300E air quality module 2 and preheat, when after the preheating time reaching program setting, the detected value of read module, then, the value of humiture and air quality is stored in memory chip, if the value of humiture and air quality exceedes the setting value of program, it is judged in preserving jar air exception or article have variation, program makes PA4 mouth output high level, open communication module 5, and the detected value of humiture and air quality is sent, notify related personnel.After data are sent, make PD0, PA4, PD1 mouth output low level, close TH02 humiture module 1, communication module 5, AQM-300E air quality module 2, reduce power consumption.
Under this awakening mode, in order to save electric energy, it is also possible to be not turned on LCD and show.
Two, user presses any one button of ADD, SEND, START, CLEAR, MCU can be waken up, and open TH02 Temperature and Humidity module 1 and AQM-300E Detection of Air Quality module 2 simultaneously, the detected value of read module, and it is stored in memory chip, open LCD simultaneously and show, by the Item Number before dormancy, the value of the corresponding natural law of article storage and the epidemic disaster of detection in real time and air quality, is shown on LCD, and completes corresponding operation according to keypress function.After completing corresponding operating, if not having button operation within the time of program setting, closing all modular power sources, MCU reenters resting state.
When if desired taking out article in preserving jar, then pull open compression button 801 with hands, open cover 9, choose certain storage numbering position, article are taken out, then, by pressing ADD key, press CLEAR key, remove the information such as storage natural law of this Item Number, LCD shows that natural law '--' is empty simultaneously, represents that this numbering position has not had article.So move in circles.
The present invention can use common batteries to power, and directly changes battery when undertension；Rechargeable battery can also be adopted to use, charged to rechargeable battery by the charging socket 907 on Fig. 2, when battery electric quantity deficiency, it is possible to the DC source plugging 9V～30V is that rechargeable battery charges, to facilitate battery to reuse, it is ensured that the long-time normal operation of preserving jar.
