description	The utility model provides a direct-current electric arc furnace bottom electrode temperature accurate measuring device which comprises a thermocouple, a wireless transmitter, a wireless receiver, a 485 communication data processing module, a PLC (programmable logic controller) and an upper computer. The temperature data detected by the thermocouple is transmitted to the wireless receiver through the wireless transmitter, the wireless receiver is connected with the 485 communication data processing module, the 485 communication data processing module is installed on the PLC, the wireless receiver transmits the received temperature data to the PLC, and the PLC is connected with the wireless transmitter. And the temperature data is converted in the PLC and is transmitted to the upper computer for temperature display. The device is not influenced by steel slag splashing, mechanical collision and the like, the measurement precision is high, the failure rate is low, the service life is prolonged, and the maintenan
