Abstract

An event notification system utilizing a common communication protocol, a common order of data presentation, and a common field size for each data block so that at least one receiving terminal location at any location is able to receive event notification messages from at least one central station computer at participating company'"'"'s central station. Security access codes are provided, assuring that receiving terminal locations and central station computers are only able to recognize, send and receive messages with each other.

Claims

1. System for transmitting event information comprising:

a. means for entering and storing location-related predetermined information for call-up in a central station computer, and in a manner for fitting into established data fields;

b. means for calling up and displaying said data for review and means for adding operator-provided information comments at said central station computer;

c. means in said central station computer for assembling event-related-data for transmitting from said central station computer;

d. means in said central station computer for incorporating said data into standardized event information messages including order of data and maximum size of each data field of the data;

e. means for transmitting said event information message including utilizing means of a standardized communication protocol from said central station computer to at least one remote location terminal connected to said central station computer during transmission of said even information message;

f. means for receiving a transmitted event information message at the remote location terminal; and

,

g. means for selecting and displaying remote-location-terminal-selected data fields from received the event information message according to means of a predetermined display format at said remote location terminal.

2. System of claim 1 including means for recording and storage for subsequent retrieval of said event information messages at said central station computer.

3. System of claim 1 including means for electronic recording and storage for subsequent retrieval of said event information messages at said remote location terminal.

4. System of claim 1 including means for designating for said remote location terminal an access code which is included in said event information messages before said message transmission can obtain access to said remote location terminal.

5. System of claim 1 including means for establishing an identification code for said central station computer whereby said code is used as part of said event information message to identify said central station computer by said remote location terminal.

6. System of claim 1 including means for storing a central station computer identification code in at least one of said remote location terminal to which said central station computer is authorized to send said event information messages.

7. System of claim 1 including means for acknowledging receipt of clear event information messages at said remote terminal location.

8. System of claim 1 including means for request repeat message transmission in the event of a garbled or incomplete message when received in said remote terminal location.

9. System of claim 1 including means for an event notification system management computer means to acknowledge and respond to requests for updates from said central station computer and said remote location terminal.

10. System of claim 1 including means for each of said central station computer to request access codes for all said remote location terminals to which said central station computer is authorized to send event information messages.

11. System of claim 1 including means for each of said remote location terminal to request identification codes for said central station computer that are authorized to send said event information messages to said remote location terminal.

12. System of claim 1 including a means for message transmission test capability that enables said central station computer to test and to send said event message to said remote location terminal after time intervals determined for each of said remote location terminal whereby a time interval is restarted each time a transmission is made from said central station computer to one of said remote location terminal which prevents unnecessary message transmission.

13. System of claim 1 including means for assigning and storing identification codes and remote location terminal access codes in said central station computer, and an event notification system management computer for communication to said central station computer and said remote location terminal.

14. System of claim 13 including means for said event notification system management computer to transmit to predetermined selected central station computer identification codes and selected remote location access codes of said central station computers and of said remote location terminals when queried by said central station computers and said remote location terminals in direct reply to said queries.

15. System of claim 13 including means for said event notification system management computer to change access code assigned to said remote location terminal and said central station computer.

16. System of claim 13 including means for said event notification system management computer to assign alternative access code to remote location terminal, and means to assign separate authorized time periods during which each access code will be accepted by said remote location terminal.
