Description

technical field [0001] The embodiments of the present invention relate to the technical field of temperature control, and in particular to a heating element detection system, method, device and storage medium. Background technique [0002] Extrusion equipment is required in the production and manufacture of optical cables and cables. When half of the heating elements of the extrusion equipment fail, the extruded plastic in that part of the heating element failure will not be completely melted, which will cause the product to fall off or even directly scrapped. At the same time, repeated occurrence of non-melting material will also cause certain damage to the screw, screw boring and mold of the extrusion equipment, and increase the cost input. [0003] Whether the failure of heating elements can be detected in time directly determines the quality of the product. There are a large number of heating elements in each production line and failures may occur every minute. It is al...

Problems solved by technology

[0004] The existing heating element fault detection methods mainly include two types, one is the resistance detection method, which uses a multimeter and other equipment to detect the resistance value of the heating element, and then compares it with the theoretically calculated value, but only when the heating stops and the line is disconnected The other is the current detection method, which uses a clamp meter to detect the current of the heating line, and then compares it with the theoretical calculation value, but it is not practical in the PID temperature control system , because the on-off operation of the PID temperature control system is too frequent, the instantaneous current of the heating element will be too large. At this time, the fault detection and judgment of the heating element is not accurate. At the same time, the workload is heavy, and the effect of automatic detection cannot be achieved.
