| Abstract: | To further enhance the output signal voltage precision of intelligent over-current protection testing instruments, the tem- perature control system can set temperature threshold through the combination of SET key and ADD, DEC key. The temperature can be displayed by eight section common anode nixie tube, the changes in temperature can be perceived with temperature sensor DS18B20 components. When instruments work temperature is higher than the set, control system can open exhaust fan through the relay actuator, and the buzzer alarm temperature threshold also can be set up. The temperature control system based on single chip has the advantages of energy conservation, simple in structure, convenient in operation, show intuitional and higher precision etc, the research supplies further scientific reference and basis to further improve the over-current protection testing instruments signal accuracy. |
