Abstract

Disclosed is a supervisory control system for remotely monitoring and controlling at least one operational device. The system includes at least one microremote in association with an operational device and includes an input device for receiving a signal indicative of a parameter associated with the operational device and logic circuitry for controlling the operation of the microremote. A microcomputer is in communication with the microremote(s) by way of a communication link, and includes input devices for receiving the signal from the microremote, a memory device for storage of a program or algorithm, and a microprocessor for controlling the operation of the microcomputer and for utilizing the program or algorithm for operation of the supervisory control system. A personality module is removably placed in communication with the microcomputer and includes logic circuitry for controlling the operation of the personality module, and a memory device for storage of at least one program or algorithm. The personality module provides the program or algorithm to the memory device in the microcomputer for use thereby to provide supervisory and control directions for operation of the overall supervisory control system.

Claims

1. A supervisory control system comprising:

(a) at least one microremote in operative communication with outputs associated with an operational device, the microremote comprising;

input means for receiving a signal representative of a parameter associated with the operational device, and

logic circuit means for controlling the operation of the microremote;

(b) a microcomputer in communication with the microremote by a communication link;

the microcomputer comprising;

means for receiving the signal from the microremote;

memory means for storage of at least one algorithm; and

microprocessor means for controlling the operation of the microcomputer and for utilizing the signal from the microremote in conjunction with the algorithm for operation of the supervisory control system; and

(c) at least one personality module in communication with the microcomputer, the personality module comprising;

memory means having at least one algorithm stored therein for communication to the memory means of the microcomputer, and

logic circuit means for controlling the operation of the personality module.

2. The system of claim 1 wherein the microcomputer includes means for generating an operational control directive in response to the signal and to provide the directive to the microremote through the communication link, and the microremote includes means to receive the directive and communicate the directive to means for effectuating change in the operating device.

3. The system of claim 1 wherein the communication link provides two way data transfer over a medium selected from the group consisting of fiberoptical cable, coaxial cable, telephone line, radio, and combination of these.

4. The system of claim 3 wherein all communication occurs serially within the system.

5. The system of claim 4 wherein the microremote and the microcomputer each include a UART in conjunction with the communication link.

6. The system of claim 5 wherein the microremote and the microcomputer each include an optocoupler in conjunction with the communication link.
