Problems solved by technology

This type of recorder can only record, but cannot output data through the liquid crystal and directly save the recorded data, nor can it directly print the recorded data through the printer and directly print out the curve change graph of temperature and humidity. To complete these operations, it cannot be separated from the computer. It is very difficult to complete on site, which has great limitations and is not conducive to the management of temperature and humidity on site

Abstract

The temperature and humidity collecting recorder consists of data acquiring circuit, data memory circuit, program memory circuit, output circuit, clock control circuit, alarm circuit, functional operation control circuit and power source circuit. The temperature and humidity information, data through processing in the program memory circuit and Chinese character information are stored in the data memory. Date, time, temperature, humidity, user mark and other information are saved. The present invention combines sensor technology and computer technology and has the integral functions of data acquisition, Chinese character display, data printing and graph printing.

Description

technical field [0001] The invention relates to a testing instrument, in particular to a temperature and humidity acquisition recorder, a manufacturing method and a data management and analysis method. Background technique [0002] Whether it is products, commodities or intermediate products, there are corresponding requirements for temperature and humidity in the process of storage and maintenance. Changes in temperature and humidity will affect the quality of products, especially medical supplies, food and chemical products. Temperature and moderation requirements are extremely stringent. The usual method is to detect temperature and humidity manually, and place the temperature and humidity measurement instruments in the testing site. The testers regularly record the data displayed by the temperature and humidity measurement instruments. After manually drawing the data, the curve changes of temperature and humidity are drawn, and then analyzed. Although the instrument de...
