Communication path integrity supervision in a network system for automatic alarm data communication
First Claim
1. A method of communication path integrity supervision for a system of automatic alarm data communication of the type having a communications network, a plurality of automatic alarm data transmitters on the network for transmitting alarm messages including check-in messages of which some are check-off messages that a transmitter utilizes to quit until further notice from continuing participation in said method of communication path integrity supervision, at least one receiver on the network for receiving the message traffic of the transmitters, a check-in protocol shared by the receiver and transmitters which establishes a time interval for the scheduling of each next-due check-in message, wherein said receiver is provided with a computer-implemented process for organizing the check-in message traffic from the transmitters in an appointment schedule by:
- for each received check-in message, determining if it is a check-off message, otherwise scheduler rescheduling an appointment in the appointment schedule for this transmitting transmitter for a next-due check-in based upon the check-in protocol'"'"'s time interval; and
monitoring the appointment schedule for any occurrence of an unmet appointment, which signifies problems with integrity;
said method comprising the steps of;
providing any transmitter participating in said method with a process for self-empowering the transmitter to periodically test its ability to establish communication with the receiver by;
generating a check-in message;
transmitting such check-in message over the network; and
, before expiration of a next-due check-in message as determined according to the check-in protocol'"'"'s time interval, returning to the above step of generating a message, hence generating a succeeding check-in message; and
thereby the receiver may correspond the occurrence of any unmet appointment with problems with integrity;
whereby said method liberates the receiver from having to poll the participating transmitters by address for response in order to test each'"'"'s ability to get through with communications.

Abstract
A communication path integrity supervision system is provided for a network of automatic alarm data transmissions. A plurality of alarm data transmitters are linked by diverse paths with a central receiver for such automatic alarm data, wherein the responsibility for carrying out integrity supervision has been largely shifted onto the remote transmitters—each responsible for its own path or paths—and shifted away from the central receiver to the extent required by the prior art “receiver-polling” protocol. Hence each transmitter generates and sends to the central receiver a succession of check-in messages. The central receiver responds to each such message by updating a table of such messages, scheduling or rescheduling the next check-in as applicable to that particular remote transmitter. An alert is signaled whenever any remote transmitter fails to meet its scheduled or rescheduled check-in. Given the foregoing, the integrity of the communication paths are supervised.
