High-strength prestressed rare-earth galvanized stranded wire stabilization temperature warning control circuit

The utility model relates to a high-strength prestressed rare-earth galvanized stranded wire stabilization temperature warning control circuit. A single-ended comparator consisting of two NE555s serves as a converting circuit for a temperature-sensing signal, an O-10V voltage signal fedback by a temperature measuring instrument is loaded to a point A, a temperature signal detected by the temperature measuring instrument is loaded to a pin (6) of the NE555 in an analog quantity mode, a pin (3) of the NE555 is used for outputting an alarm signal, and a control contact point J1 of a relay J is connected to a PLC. When the circuit is used, the temperature of the galvanized stranded wire is measured through the temperature measuring instrument, when the temperature exceeds the alarm temperature, the buzzer gives a sound, and when the temperature of the galvanized stranded wire is continued to rise, the production line gives an alarm for stopping. Since a warning area and a limit area are additionally arranged resp
