Method of integrating wired and wireless tank gauging systems on flexible common gateway hardware

A tank gauging system comprising:

• a tank inventory system configured to monitor an inventory in a tank;
• a tank gauging equipment configured to measure a level of the inventory in the tank;
• and
• a communication interface (CIU) apparatus comprising of:
• a serial connection configured to communicate with the tank inventory system;
• a memory configured to store a CIU application and a wireless application consisting of:
• a wireless gateway and a wireless device manager that communicates with and collects data from a wireless tank gauging equipment via wireless access points;
• and
• a wired tank gauge communication protocol that communicates with and collects data from a wired tank gauging equipment over the serial connection;
• a plurality of Ethernet connections each Ethernet connection configured to connect to a switch to wirelessly communicate with the tank gauging equipment using the wireless application, each of the plurality of Ethernet connections including a software port, and each software port configured to communicate between the CIU application and the wireless application, wherein each software port includes connections for CIU applications and wireless applications, and the wired tank gauging equipment can be configured under each software port;
• and
• a processor coupled to the memory, serial connection and the Ethernet connection, the processor configured to:
• receive, via the serial connection, a command message from the tank inventory system using the CIU application,
• transmit, via the Ethernet connection, the command message to the tank gauging equipment using the wireless application,
• receive, via the Ethernet connection, a response message from the tank gauging equipment using the wireless application,
• transmit, using the serial connection, the response message to the tank inventory system using the CIU application, and
• wherein the serial connection includes a plurality of serial connections used to communicate with wired tank gauging equipment in parallel with communication of wireless tank gauging equipment using the CIU application.
