Buried pipeline cathode protection data transmission system

The invention discloses a buried pipeline cathode protection data transmission system. The buried pipeline cathode protection data transmission system comprises a buried pipeline cathode protection data collection device, a wireless data aggregation device and a wireless communication gateway. The buried pipeline cathode protection data collection device collects buried pipeline cathode protection data information to be processed, and the buried pipeline cathode protection data information is transmitted to the wireless data aggregation device through a wireless network after being stored. The wireless data aggregation device aggregates the buried pipeline cathode protection data information transmitted by the buried pipeline cathode protection data collection device, and the buried pipeline cathode protection data information is transmitted to the wireless communication gateway through the wireless network. The wireless communication gateway is in communication connection with the Internet, and transits the buried pipeline cathode protection data information to an upper computer through the Internet. The wireless network formed by the wireless data aggregation device or the buried pipeline cathode protection data collection device guarantees the timeliness, reliability and authenticity of pipeline stray current and cathode protection testing data.
