Technical Field

[0001] The present invention relates to the technical field of temperature and humidity monitoring in curing barns, and particularly to an intelligent temperature and humidity monitoring method and system for flue-cured tobacco or fruits and vegetables. Background Art

[0002] Currently, well-known flue-cured tobacco temperature and humidity meters all use two identical temperature sensors for detection. For example, in the patent application with the patent number CN1408287A, the relative humidity data is obtained by a temperature sensor plus water, that is, the temperature value of the temperature sensor under saturated humidity (water). Therefore, the relative humidity data measured by one of the temperature sensors needs to add water to be accurate. And due to the high-temperature and high-humidity environment, the accuracy of a simple humidity sensor decreases, resulting in inaccurate humidity data measured by it. However, in actual operation, it is easy to damage the tobacco or fruits and vegetables due to inaccurate relative humidity data caused by forgetting to add water during use, and it is very time-consuming and laborious to add water to the hot curing barn every time.

[0003] In view of this, it is necessary to provide an intelligent temperature and humidity monitoring method and system for flue-cured tobacco or fruits and vegetables to overcome the above defects. Summary of the Invention

It should be understood that the specific embodiments described in this specification are only for explaining the present invention and not for limiting the present invention.

[0030] It should also be understood that the terms used in this specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. As used in this specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an" and "the" are intended to include the plural forms.

[0031] It should be further understood that the term "and / or" used in the specification and appended claims of the present invention refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0032] Embodiment 1

[0033] In an embodiment of the present invention, a temperature and humidity intelligent monitoring system for flue-cured tobacco or fruits and vegetables is provided, which is used to monitor the temperature and humidity of a curing barn without the need to regularly enter the curing barn to add water to maintain the humidity detection accuracy.

[0034] As Figure 1 shown, the temperature and humidity intelligent monitoring system 100 for flue-cured tobacco or fruits and vegetables includes: a temperature sensor 10, a humidity sensor 20, an arithmetic processing chip 30, a power supply module 40, and a wireless communication module 50.

[0035] The temperature sensor 10 is used to collect the ambient temperature signal and send the temperature signal to the arithmetic processing chip 30.

[0036] The humidity sensor 20 is used to collect the ambient humidity signal and send the humidity signal to the arithmetic processing chip 30.

[0037] Among them, the humidity sensor 20 and the temperature sensor 10 are respectively installed on the top and side wall of the curing barn to avoid signal interference with each other. It should be noted that the specific structures and implementation principles of the temperature sensor 10 and the humidity sensor 20 can refer to the prior art, and the present invention does not limit them here. Further, the surface of the humidity sensor 20 is coated with a hydrophobic coating and is configured with a self-cleaning circuit to periodically remove attachments through micro-vibrations to avoid impurities such as tobacco oil from adhering to the surface of the humidity sensor 20, thereby reducing the sensing accuracy of the sensor.

[0038] The arithmetic processing chip 30 is used to perform humidity calibration by executing a preset humidity compensation formula based on the received temperature signal and humidity signal, and output temperature data and calibrated humidity data; where the humidity compensation formula is:

[0039] H1 = (T0 - k) + α·H0;

[0040] In the formula, H1 is the calibrated humidity data, T0 is the collected ambient temperature signal, k is the temperature compensation base number (for example, k = 2), α is the humidity linear conversion coefficient (for example, 0.01), and H0 is the collected ambient humidity signal.

[0041] Specifically, the temperature signal is divided into two paths for use. One path directly converts the temperature signal into the displayed temperature data for output, and the other path performs the above humidity calibration operation processing on the temperature signal and the humidity signal collected by the humidity sensor 20 to obtain the displayed humidity data. For example, the temperature signal data collected by the temperature sensor 10 is 36 °C, the temperature compensation base k is 2, and the signal data collected by the humidity sensor 20 is 80%, and the converted value is 80 * 0.01 = 0.8. Then the calibrated relative humidity value is 36 - 2 + 0.8 = 34.8.

[0042] Furthermore, the operation processing chip 30 is also integrated with an edge computing unit and a local storage unit. The edge computing unit is used for edge computing humidity data calibration. The local storage unit is used to store the temperature and humidity data for a preset number of days, and continuously record and trigger an alarm when the network is disconnected.

[0043] The wireless communication module 50 is used to transmit the temperature data and the calibrated humidity data to a preset terminal device (such as a mobile phone, a tablet computer, a laptop, etc.). Furthermore, the wireless communication module 50 performs data transmission through Wi-Fi and Bluetooth dual modes to ensure the stability of data transmission, reduce the risk of data transmission loss, and synchronize the temperature and humidity data to the cloud platform and the mobile phone APP to achieve remote monitoring and historical data query.

[0044] The power supply module 40 is used to supply power to the entire system.

[0045] Specifically, the power supply module 40 includes a lithium battery, a solar charging unit, and a low-power management unit. The solar charging unit is arranged on the outer top of the baking room and is used to receive light energy to supply power to the system and charge the lithium battery. That is, when there is solar energy, the system can be powered by the solar charging unit; when the solar energy is insufficient, the lithium battery can be used to supply power to the system. The low-power management unit is used to automatically switch between the solar power supply and the lithium battery power supply mode according to the ambient light to improve the battery life of the system.

[0046] Furthermore, the intelligent temperature and humidity monitoring system 100 for flue-cured tobacco or fruits and vegetables also includes an alarm module 60. The alarm module 60 includes a buzzer, and / or a speaker, and / or an LED indicator light, and its trigger threshold is pre-configured through a terminal device (such as the flue-cured tobacco mode: temperature 35 - 45 °C, humidity 60 - 80%). When at least one of the temperature or humidity in the baking room is abnormal, the alarm module 60 can give a reminder in the form of vibration, sound, light, and their combinations to prevent the flue-cured tobacco or fruits and vegetables in the baking room from being over-baked.

[0047] Embodiment 2

[0048] The present invention also provides a method for intelligent monitoring of temperature and humidity of flue-cured tobacco or fruits and vegetables, which is implemented based on the above-mentioned intelligent monitoring system 100 of temperature and humidity of flue-cured tobacco or fruits and vegetables and is used to monitor the temperature and humidity of a curing barn. Specifically, the method includes the following steps S10-S30.

[0049] Step S10: Collect ambient temperature signals and ambient humidity signals.

[0050] Step S20: Perform humidity calibration by executing a preset humidity compensation formula based on the received temperature signal and humidity signal, and output temperature data and calibrated humidity data; wherein, the humidity compensation formula is:

[0051] H1 = (T0 - k) + α·H0;

[0052] In the formula, H1 is the calibrated humidity data, T0 is the collected ambient temperature signal, k is the temperature compensation base, α is the humidity linear conversion coefficient, and H0 is the collected ambient humidity signal.

[0053] Step S30: Transmit the temperature data and the calibrated humidity data to a preset terminal device.

[0054] In summary, for the method and system for intelligent monitoring of temperature and humidity of flue-cured tobacco or fruits and vegetables provided by the present invention, first, a humidity sensor 20 is used to replace one temperature sensor 10 in the traditional measurement method to collect the humidity of the curing barn environment. Then, an arithmetic processing chip is used to perform humidity calibration arithmetic processing on the humidity signal collected by the humidity sensor 20 and the temperature signal collected by the other temperature sensor 10, and then respectively output temperature data and calibrated humidity data. There is no need to add water in the hot curing barn, and the temperature and humidity conditions in the curing barn can be remotely and timely grasped through the wireless communication module, improving the baking quality of flue-cured tobacco or fruits and vegetables in the curing barn.
