An on-site verification/calibration system and method for a blast drying oven

Abstract

The invention relates to a system and a method for onsite verifying or correcting of a forced air drying box. The method includes using a mobile terminal to download an onsite correcting program from a network cloud server, scanning an electronic tag to read and write basic information verifying or correcting record of the drying box, uploading the information and verifying or correcting result of the drying box to the network cloud server through a Bluetooth function monitoring onsite corrector, and updating verifying or correcting result in the electronic tag; using network cloud management software to download the verifying or correcting result from the cloud server, generating a correcting report, and printing a verifying or correcting certificate. The electronic tag is scanned through the mobile terminal to read and write the basic information and the verifying or correcting record of the drying box, so that workload and errors are reduced, and long-time storing of verifying or correcting information is facilitated; the network cloud management software downloads the verifying or correcting result from the network cloud server and generates the verifying or correcting report, so that manual calculating and checking of the verifying or correcting result are avoided, working efficiency is improved, and period for issuing the verifying or correcting certificate is shortened.

Description

technical field [0001] The invention relates to the field of measurement verification / calibration of a drying oven, in particular to an on-site verification / calibration system and method for a blast drying oven. Background technique [0002] Electric blast drying ovens are widely used in industry, agriculture, medical treatment, plastic machinery, production workshops and scientific research experiments. With the rapid development of China's economy, drying oven equipment manufacturers have made great progress, and their applications are very extensive, and they also have a certain weight in the domestic market. However, many manufacturers produce low-tech, low-quality, and low-cost drying boxes for profit, which seriously affects the overall competitiveness of China's drying box industry, which makes it more and more difficult for quality and technical supervision departments to supervise drying boxes. The blast drying oven can realize heating, heat preservation, cooling a...

Problems solved by technology

Usually a standard mercury thermometer is used to calibrate the dry box, which requires manual monitoring and recording of data, which consumes a lot of manpower and material resources, and with the large increase in the output of the dry box, this method can no longer meet the calibration needs of mass production of the dry box; some Manufacturers and verification personnel use temperature sensing probes instead of traditional mercury thermometers as temperature sensing elements, and there are already some smart portable temperature calibration systems on the market. These systems can automatically record temperature data, and have their own Bluetooth module to send and receive data, which improves work efficiency. , but it is necessary to manually transcribe the equipment information and record the calibration results. There may be fraud and mistakes in the middle link, which may cause unqualified products to flow into the market, which is not conducive to the supervision of the quality supervision department, and the staff of the quality supervision department need to bring the calibration results back for calculation and review. Long period for issuing certificates
