摘要： This system connects groups of end-devices at two or more automated oil or gas production wellheads or groups of end-devices at two or more associated wellhead facilities so that such associated end devices may be wirelessly monitored and measured during wellhead production, and then wirelessly controlled by one or more master remote terminal/telemetry unit MRTU. Each MRTU is in turn in communication with and controlled by a host computer system. Such measurement and control of the end devices is accomplished through slave remote terminal/telemetry units SRTUs which are connected to and capable of communications with associated end-devices. Each SRTU is in turn connected to one or more local area network LAN communication system, each of which LAN is in turn connected, by hard wire or wirelessly, to a wide area network WAN transmitter. Each WAN is in wireless communication with a host computer.
