Description

A kind of humiture registering instrument

Technical field

The utility model relates to a kind of recording unit, is specifically a kind of humiture recording unit of the humiture situation being monitored, being reported to the police with transportation of preserving for agricultural product.

Background technology

In recent years, China's agriculture product such as fruit, vegetables etc. have obtained significant progress, and output also leaps to the first in the world.But because the water cut of the agricultural products such as fruit, vegetables is higher, rot very fast, and store method is improper, therefore can cause huge waste, wherein the rotten proportion of goods damageds of fruits reach more than 35%, and greengrocery is especially up to 50%, the proportion of goods damageds of external advanced country are less than 10%, therefore, to the preservation monitoring of agricultural products, the rate of reducing the wastage is an important research topic.

Temperature and humidity are agricultural products two important factors in the preservation process, and wherein temperature is to affect fruits and vegetables to breathe strong and weak key factor, and temperature raises, and the generation of respiration, transpiration and ethene etc. all can be accelerated, and moisture, nutrient loss accelerate.These all can reduce keeping quality and the disease resistance of product; And humidity major effect fruit weightlessness and disease, humidity is too low, and the dehydration shrinkage is when the excessive and temperature of humidity is high, very easily rotten.

The variety classes fruits and vegetables are not quite similar to the requirement of ambient humidity.Therefore the Real-time Collection of the humiture preserving, in transportation and record not only can provide reliable basis for the fresh-keeping condition of keeping and improve the fruits and vegetables accumulating, and help to improve the ageing and efficiency of product stream management, the accumulating allotment is played directive function, and then to significantly reducing economic loss, have great significance.

Summary of the invention

For present situation, the utility model provides a kind of and has preserved and transportation for agricultural product, the humiture registering instrument that can effectively monitor, record and report to the police, temperature in the preservation process and humidity are monitored, provide actively foundation reliably to improving the preservation environment, to environment and the alarm that does not meet preservation condition.

The utility model is mainly realized by following technical scheme: a kind of humiture registering instrument, mainly comprise main control module, the humiture detection module, RFID module, load module, interior memory module, external memory module and alarm module, described main control module respectively with the humiture detection module, RFID module, load module, interior memory module, external memory module and alarm module are connected;

Described main control module is the ATmega16 chip;

Described humiture detection module is the HSU-07J6T sensor;

Described RFID module is the ZLG500 module;

Described load module is capacitance touch screen;

Described internal storage is the flash storer;

Described external memory module is micro SD card;

Described alarm module is hummer.

This humiture registering instrument can be monitored preserving environment in real time, the correct related data that gathers, and data are recorded in respectively simultaneously in the RFID electronic tag of SD card and product, can check by the electronic tag that reads on product in the time of need to checking data, analysis as further in needs can snap fit onto SD on the PC terminal and check analysis; Can notify the custodial staff by warning device when environmental baseline exceeds preset value, by the custodial staff, in time adjust the preservation environment.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Wherein 1 is main control module, and 2 is the humiture detection module, and 3 is the RFID module, and 4 is load module, and 5 is interior memory module, and 6 is the external memory module, and 7 is alarm module, and 8 is electronic tag.

Embodiment

Referring to Fig. 1, this humiture registering instrument mainly comprises main control module 1, humiture detection module 2, RFID module 3, load module 4, interior memory module 5, external memory module 6, alarm module 7, wherein main control module 1 respectively with humiture detection module 2, RFID module 3, load module 4, interior memory module 5, external memory module 6 and alarm module 7 are connected; Main control module 1 is the ATmega16 chip; Humiture detection module 2 is the HSU-07J6T sensor; RFID module 3 is the ZLG500 module; Load module 4 is capacitance touch screen; Interior memory module 5 is the flash storer; External memory module 6 is micro SD card; Alarm module 7 is hummer.

During work, the agricultural product that line is preserved needs are preset corresponding temperature value and humidity value by load module 4, and main control module 1 is stored in it in interior memory module 5; After the equipment operation, humiture detection module 2 is inputted data in real time main control module 1 and is processed, data after main control module 1 will be processed are recorded in external memory module 6, send to simultaneously RFID module 3, and 3 of RFID modules send data and be recorded in the RFID electronic tag 8 of agricultural product.When the value of the temperature that detects or humidity had surpassed the preset value that is stored in interior memory module 5, main control module 1 started alarm module 7, informs the custodial staff, by the custodial staff, to preserving environment, was improved.
