III Wireless transmission equipment

The transmission equipment adopts a stable GPRS communication module, installed near the wellhead, and transmits to the data receiving center through the GPRS network.

The data transmission adopts GPRS wireless technology that binds IP addresses. The central station and each monitoring point have a fixed wireless IP address, and the data is directly transmitted to the user's computer through the GPRS network router. Users do not need to access the special line of the mobile company or connect to the Internet.

4、 On site power supply

The on-site equipment is powered by 12V DC. To ensure reliable power supply, it is usually necessary to equip with batteries, charging controllers, and external power sources (solar panels or external DC stabilized power sources).

5、 Central Station

The central station is responsible for information acquisition, storage, display and printing, and remotely synchronizing the internal clock of sensors. There are two ways to obtain on-site sensor data:

1. Regularly send collection commands to each telemetry station through the central station to collect real-time water level and temperature data.

2. The central station can also batch call historical data from on-site sensor memory.

The operating platforms are WINDOWS XP operating system and SQL Server database system. Summarize, retrieve, display charts, and print the received data. The central station software supports querying and displaying within the local area network.
