Wireless temperature and humidity probe for cold chain, and using method thereof

Abstract

The invention discloses a wireless temperature and humidity probe for a cold chain, and a using method thereof.The wireless temperature and humidity probe comprises a shell, mounting plates, fixing holes and fixing bolts, the mounting plates are arranged at the two ends of the upper wall and the lower wall of the shell correspondingly, a shock pad is arranged on one side wall of each mounting plate, and the fixing holes are formed in the mounting plates and the shock pads correspondingly; and the fixing bolts are arranged in the fixing holes, a circuit board is arranged in the shell, and a power line is arranged on one side wall of the shell. The probe has the beneficial effects that by arranging an airflow sensor, a motor and a turntable, in the working process of a device, the airflow sensor detects the airflow in the device, and transmits detection data to the controller, and the controller controls the motor to act to drive the turntable to rotate, so that the temperature detectionprobe rotates, the detection angle of the temperature detection probe is adjusted, the influence of airflow on the temperature detection probe is avoided, the detection precision is ensured, and thepracticability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of cold chain equipment, in particular to a wireless temperature and humidity probe for cold chain and its usage method. Background technique [0002] The cold chain refers to certain food raw materials, processed food or semi-finished products, special biological products and pharmaceuticals after they are purchased, processed and inactivated, during the process of product processing, storage, transportation, distribution, retail and use. The link is always in the specific low temperature environment necessary for the product to reduce loss, prevent pollution and deterioration, and ensure the special supply chain system of product food safety, biological safety, and drug safety. [0003] The existing wireless temperature and humidity probes for cold chain will be affected by the airflow in the cold storage during the detection process, which will lead to certain errors in the temperature detection results, ...

AI Technical Summary

Problems solved by technology

[0003] The existing wireless temperature and humidity probes for cold chain will be affected by the airflow in the cold storage during the detection process, which will lead to certain errors in the temperature detection results, resulting in higher or lower detection data than the actual data, reducing the practicability of the device. Secondly, Because the detection height of the existing wireless temperature and humidity probes for cold chain is fixed, the device cannot detect the temperature and humidity at different heights in the cold storage, resulting in uneven temperature and humidity in the cold storage and reducing the functionality of the device. In addition, the existing The wireless temperature and humidity probe for cold chain is easily affected by cold air during the detection process, and at the same time, a layer of dust is easy to adhere to the surface of the detection probe, which will affect the performance of the device and reduce the working effect of the device. Therefore, there is an urgent need for a cold chain. Wireless temperature and humidity probe to solve existing problems
