The method comprises the steps that by means of a ZigBee wireless networking technology, on-site monitoring of a PC or a cellphone APP on multiple ZigBee temperature and humidity collection terminals on a job site; by means of an Internet network technology, the PC or the cellphone APP can upload collected data to a remote server; the remote server achieves temperature and humidity data storage, curve analysis and temperature and humidity warning functions, and meanwhile the remote server automatically generates a calibration report through error analysis of a field instrument. The temperature and humidity inspection and calibration system is set up by means of the ZigBee networking technology, a large amount of wiring is not needed, the cost and the construction difficulty are greatly lowered, the function is more flexible, and development is convenient and rapid.

Description

Technical field [0001] The invention relates to the field of temperature and humidity inspection and calibration methods, in particular to a wireless networked temperature and humidity inspection system and calibration method. [0002] technical background [0003] In production and life, it is often necessary to monitor the temperature and humidity of a large controlled object in real time. Because the temperature and humidity of each part of the controlled object may be different, in order to better control the temperature and humidity of each part of the system, a multi-channel temperature and humidity inspection system is usually used. At present, the multi-channel temperature and humidity inspection system is widely used in industry, agriculture, medical treatment, plastic machinery, production workshops and scientific research experiments. [0004] At present, most of the temperature and humidity inspection systems for multi-channel measuring points use wired communication to ...

Problems solved by technology

[0004] At present, most of the temperature and humidity inspection systems of multi-channel measuring points use wired communication to realize real-time monitoring of the temperature and humidity of multiple detection points, but this method has certain limitations and is only suitable for small-scale and less detection In the case of a large range and a large number of detection points, a large number of complex wiring is required, which consumes a large cost, takes up a large amount of space, and has great difficulty in system construction. The following disadvantages:

[0005] (1) After the system layout is completed, since each part of the system communicates through connections, each temperature and humidity detection point is relatively fixed, and in many cases it is impossible to change the detection point at will according to actual needs;

[0006] (2) Too long connection between the detection point and the host computer will cause errors in the transmission process of the collected signal, so that it cannot accurately reflect the true value of temperature and humidity at each temperature and humidity detection point;

[0007] (3) In the case of many detection points, due to the use of a large number of complex wiring, when the system fails, it is not conducive to the troubleshooting of the system;

At present, the calibration of temperature and humidity sensors generally adopts the manual manual on-site calibration method. The generation of the calibration report requires a large amount of data processing, which requires a lot of manpower and material resources.
