Abstract

A two-way wireless communications system for permitting the control, monitoring and collection of data from electrical apparatus includes a host computer, control and monitoring units remotely located from the host computer, and subscriber software for establishing communication protocol with each unit. The host computer includes a customer interface gateway which handles communications from the subscriber software to the host system, a wireless service gateway which handles all communications with the remotely located units, and a product data processor for processing data obtained from either a customer via the subscriber software or a particular remote unit. The subscriber software permits customers to have desktop control of their electrical apparatus associated with a remote unit. Each remote unit contains a motherhood, power supply, and modem. Each unit is capable of real-time monitoring and control of the electrical apparatus associated with the unit.

Claims

1. A system for controlling, monitoring, and collecting data from devices, comprising;

a host computer including an internal memory for storing a plurality of protocols for a plurality of applications, said computer having means for selecting one of said protocols corresponding to one of said applications and further including means for sending a text message to remote units associated with each of said devices as determined by said selected protocol, said host computer further including means for receiving a text message;

a customer interface capable of full-duplex communication with said host computer thereby having the ability to provide control of their applications and further having the ability to receive signals indicative of operational parameters of said devices;

a remote unit associated with each of said devices for controlling, monitoring, and collecting data including said selected protocol, said unit further having means for sending a text message to said host computer, said unit further including means for receiving a text message from said computer.

2. A system for the controlling, monitoring, and collecting data from electrical devices as defined in claim 1 wherein said means for sending a text message includes a protocol comprising a first and a second layer, said first layer being application independent and said second layer being application dependent.

3. A system for the controlling, monitoring, and collecting data from electrical devices as defined in claim 1 wherein said means for receiving a text message comprise a protocol having a first and a second layer, said first layer being application independent and said layer being application dependent.

4. A system for controlling, monitoring, and collecting data from electrical devices as defined in claim 3 wherein said unit includes a relay.

5. A system for controlling, monitoring, and collecting data from electrical devices as defined in claim 3 wherein said unit includes and AC current sensor.
