A JCR drying program-controlled incremental heating oven with a centralized control box device comprises a blue screen paperless recorder and a program-controlled incremental heating oven. The blue screen paperless recorder connects to the incremental program-controlled oven via a signal line. The blue screen paperless recorder is a multifunctional intelligent display instrument with signal sampling, measuring, control, display, operation, storage, communication, and data transferring functions, and comprises a high-performance 32-bit ARM processor, a multi-channel analog input end, a 10-channel relay alarm output end, and a backup data transfer output port. The invention features a reasonable design and achieves such functions as incremental temperature control, real time recording of a temperature curve during heating, real time recording of an alarm, querying of a historical temperature curve and querying of a historical alarm record. The invention is intuitive, reliable, conveniently satisfies performance criteria of existing equipment and eliminates defects in existing equipment.
