[0028] 1. Main hardware and software
[0029] 1. Hardware circuit design:
[0030] 1) Composition block diagram
[0031] Due to the large amount of data to be processed, not only data calculation, but also judgment, display, keyboard input, and communication are required, and real-time performance is required to detect and handle line faults in time. If a single MCU is used, not only the speed requirement is extremely high, but also the number of I / O ports is difficult to meet the needs. Therefore, this design adopts the framework of dual MCUs, and selects STC12C4052 and SST89E564 in a targeted manner, which are used for signal collection, judgment and communication, display, keyboard, etc. respectively.
[0032] The hardware structure block diagram of the dual-core intelligent communicable controller for molded case low-voltage circuit breakers is shown in Figure 1, which mainly includes air-core current transformers, Hall current transformers, zero-sequence current transfo...
