Application of bar code technology in air conditioning maintenance

Do you know what effect the bar code on the air conditioning label has? Similar to the installation of air conditioning, the maintenance of air conditioning is mainly done by third parties, and these maintenance points are economically independent accounting.

For maintenance within the warranty period, the manufacturer shall bear the full cost of maintenance according to the records provided by the maintenance point. Of course, the manufacturer shall carry out strict check, but it is too much work to call and check one by one according to the maintenance records, so only spot check can be carried out. Some repair shops take advantage of this, overreporting or rerecording the number of repairs to charge the manufacturer more.

Maintenance is also an important way to collect customers' opinions and expose product quality problems. Careful analysis and summary of fault phenomena and causes will be of great help to improve product quality and customer satisfaction. However, the previous manual method can only deal with a single problem in the repair, and it is impossible or difficult to find the law.

Using the historical data accumulated in the production, installation and maintenance of the bar code system, the above problems are well solved. Each maintenance record will be carefully analyzed by the computer system to check whether previous or similar maintenance records have been repeated, and whether the last repair was not completed properly, or whether the maintenance record was filled in repeatedly on purpose.

By analyzing the relationship between failures and manufacturing, storage and transportation, installation, and customer location, many deeper problems can be identified.

For example, a fault is closely related to a batch of parts from a certain supplier, or is highly related to an installation unit to determine whether a batch of products should be recalled.
