R & D and production of carbon monoxide alarm automatic test system, mainly by computer, display, IO control card, carbon monoxide analyzer, wireless router, PLC, contactor, two buffer boxes, two preheating boxes, two test boxes, control cabinet The PLC control program and the computer test program are comprehensive tests for the semi-finished functional test and finished product of the carbon monoxide alarm in the production process. The semi-finished test content mainly includes the calibration of the carbon monoxide alarm at a carbon monoxide concentration of 40 PM and 200 PPM, and After calibration, the data is transmitted to the computer through the WIFI wireless data transmission module for result determination, display and storage. The other part of the finished product test content is to place the alarms that have been calibrated in a test box with a concentration of 55PM and 110PM respectively. The WIFI wireless data transmission module is used for real-time monitoring to calculate whether the alarm time of the product is Within the normal range, the alarm time and carbon monoxide concentration values for each phase are displayed and stored.
        The carbon monoxide alarm test system has accurate test data and no false alarms. It can test 140 products at the same time. Various test parameters can be seen at a glance. The upper and lower limits of various parameters can be set. If the upper and lower limits are exceeded, the alarm will be given and each record will be automatically recorded. Product test results, easy to archive and view, data transmission is stable, all products and computer communication use WIFI wireless data connection, high reliability, easy maintenance, fully meet the requirements of carbon monoxide alarm in manufacturing, thus greatly improving production efficiency .
