S400: the data transmission unit 200 converts the WITS data into IP data.
After the data transmission unit 200 obtains the WITS data sent by the data acquisition terminal 100, the data transmission unit 200 processes the WITS data based on an IP protocol so as to convert the WITS data into IP data, where the IP data includes wellsite data encapsulated in the WITS data, in order to send the WITS data to the data server center.
S500: the data transmission unit 200 transmits the IP data to the data center server 300 through wireless communication based on the IP address and the port number.
The data transmission unit 200 is preset with an IP address and a port number of the data center server 300, and after the data transmission unit 200 converts the WITS data sent by the data acquisition terminal 100 into the IP data, the data transmission unit 200 sends the IP data to the data center server 300 in a wireless communication manner based on the IP address and the port number.

As an implementation manner, a listener code is written based on a Transmission Control Protocol (TCP), the data center server 300 monitors the IP data by operating the listener code, and when it is monitored that the IP data is transmitted to the data center server 300, the center server receives the IP data in real time through a thread.
