A site controller adapted to be used in an automated monitoring system for monitoring and controlling a plurality of remote devices via a host computer connected to a first communication network is provided. The site controller is configured for controlling communication with the host computer and a plurality of communication devices that define a second communication network associated with the plurality of remote devices. Briefly described, in one embodiment, the site controller comprises a transceiver configured to communicate with the plurality of communication devices via the second communication network; a network interface device configured to communicate with the host computer via the first communication network; and logic configured to: manage communication with each of the plurality of communication devices, via a first communication protocol, based on one or more communication paths for each of the plurality of communication devices, each communication path comprising one or more communication devices involved in the communication link between the transceiver and each of the plurality of communication devices; and manage communication with the host computer via a second communication protocol.
The invention claimed is: 1. A method for controlling communication with a host computer connected to a first communication network and a plurality of communication devices that define a second communication network associated with a plurality of remote devices that are to be monitored and controll
The invention claimed is: 1. A method for controlling communication with a host computer connected to a first communication network and a plurality of communication devices that define a second communication network associated with a plurality of remote devices that are to be monitored and controlled by the host computer, the method comprising the steps of: sending a path determination message to a target communication device from a site controller through the second communication network prompting the target communication device to retransmit the path determination message to the site controller through the second communication network, generating a network map of all down-stream communication paths from the site controller to the target communication device and all up-stream communication paths from the target communication device to the site controller from the unique addresses of the communication devices that retransmitted the path determination message from the site controller to the target communication device or from the target communication device to the site controller, based on the network map, determining one or more up-stream and down-stream communication paths associated with each of the plurality of communication devices; managing communication with each of the plurality of communication devices and the identification of each of the plurality of communication devices in the one or more communication paths, via a first communication protocol, based on one or more of the communication paths associated with each of the plurality of communication devices; managing communication with the host computer via a second communication protocol; storing on the site controller a first look-up table for identifying each of the plurality of communication devices that define a second communication network; and storing on the site controller a second look-up table for identifying a function to be performed by the site controller based upon an analysis of a message received from any one of the plurality of communication devices that define a second communication network. 2. The method of claim 1, wherein each of the plurality of communication devices are wireless communication devices, the plurality of wireless communication devices being disposed throughout a geographic area such that the antenna patterns associated with the plurality of wireless communication devices overlap to create a coverage area that defines the second communication network. 3. The method of claim 1, wherein the first communication network is a wide area network and the second communication protocol comprises TCP/IP. 4. The method of claim 1, further comprising the step of managing communication with each of the plurality of communication devices, via a first communication protocol, based on one or more of the communication paths associated with each of the plurality of communication devices wherein the first communication protocol comprises a data packet, the data packet comprising: a to address; a from address; and a command number comprising as function code. 5. The method of claim 4, wherein the data packet further comprises: a data field; a checksum field; a packet number field; a packet length field; a packet maximum field; and a message number field. 6. The method of claim 1, further comprising the steps of: receiving a request, via the first communication network, from the host computer for information related to one of the plurality of remote devices; providing a command message to the second communication network for delivery to the one of the plurality of remote devices based on one of the communication paths associated with the communication device corresponding to the one of the plurality of remote devices. 7. The method of claim 6, further comprising the step of receiving a response message, via the second communication network, that is generated by the communication device corresponding to the one of the plurality of remote devices, the response message comprising a first communication device identifier associated with the communication device associated with the one of the plurality of remote devices and a predetermined function code corresponding to a data signal provided by the one of the plurality of remote devices associated with the communication device that generated the response message; and determining, based on the first communication device identifier, the communication device that generated the first data signal. 8. The method of claim 7, comprising the step of providing the data signal to the first communication network for delivery to the host computer. 9. A method for controlling communication with a host computer connected to a first communication network and a plurality of communication devices that define a second communication network associated with a plurality of remote devices that are to be monitored and controlled by the host computer, the method comprising: sending a path determination message to each communication device from a site controller through the second communication network prompting each communication device to retransmit the path determination message to the site controller through the second communication network; generating a map of the entire network from the unique addresses of every communication device that retransmitted each path determination message from the site controller to each communication device or from each communication device to the site controller; based on the network map, determining one or more up-stream and down-stream communication paths between the controller and each communication device; managing communication between the controller and each of the communication devices based upon the network map and through a first communication protocol; managing communication between the controller and the host computer through a second communication protocol; the site controller translating a message from the host computer to a communication device in the second communication network from the second communication protocol into the first communication protocol; and storing on the site controller a first look-up table for identifying each of the plurality of communication devices that define a second communication network; and storing on the site controller a second look-up table for identifying a function to be performed by the site controller based upon an analysis of a message received from any one of the plurality of communication devices that define a second communication network. 10. The method of claim 9 further comprising, the site controller translating a message from a communication device in the second communication network to the host computer from the first communication protocol into the second communication protocol. 11. The method of claim 9, wherein a message from any one of the communication devices that define a second communication network to the host computer contains a preface and a postscript. 12. The method of claim 9, wherein the first communication protocol is an open data packet protocol.
