Abstract

A plurality of remotely-situated cable-locating transmitters (14₁-14_n) are centrally managed using a database (18) that stores information about each transmitter, including information about the particular version of its operating software. When a software upgrade becomes available, the database is accessed to identify and select those transmitters that need the upgrade. The upgrade is then communicated to each selected cable-locating transmitter, typically via a dial-up communication links (27a-27d, 28₁-28_n).

Claims

1. A method for managing a plurality of remotely-situated cable-locating transmitters from a central location, comprising the steps of:

(a) storing in a database accessible from the central location information about each of the remotely-situated cable-locating transmitters, including which version of operating software is resident at each said cable locating transmitter;

(b) accessing said database to identify which version of operating software is resident at each cable-locating transmitter;

(c) selecting among the plurality of cable-locating transmitters a set of cable locating transmitters to receive an upgrade of said operating software based on the identification of the operating software at said each transmitter;

(d) communicating to each selected cable transmitter said software upgrade; and

(e) updating said information stored in said database to reflect said upgrade to said software operating system.

2. The method according to claim 1 wherein the information about each remotely-situated cable-locating transmitter also includes:

a) a transmitter station;

b) an address for communicating with the transmitter;

c) a description of the route served by the conveyance associated with the transmitter;

d) a serial number for the cable locating transmitter;

e) a physical location of the cable locating transmitter; and

f) a date and time of transmitter installation.

3. The method according to claim 2 wherein the address for communicating with the cable-locating transmitter comprises a telephone number of a dial-up link coupled to the transmitter.

4. The method according to claim 3 wherein the selecting step includes the step of identifying those cable-locating transmitters whose operating software is older than the software upgrade.

5. The method according to claim 3 wherein the step of communicating the software upgrade includes the step of dialing the telephone number of the dial-up link coupled to the transmitter.

6. Apparatus for managing a plurality of remotely-situated cable-locating transmitters from a central location, comprising:

a database accessible from the central location information about each of the remotely-situated cable-locating transmitters, including which version of operating software is resident at each said cable locating transmitter;

a processor for (a) accessing said database to identify which version of operating software is resident at each cable-locating transmitter; and

(b) selecting among the plurality of cable-locating transmitters a set of cable locating transmitters to receive an upgrade of said operating software based on the identification of the operating software at said each transmitter and (c) updating said information stored in said database to reflect when an upgrade is made to said software operating system; and

communication means coupled to the processor and communicating with each selected cable transmitter to supply said software upgrade thererto.

7. The apparatus according to claim 6 wherein the communication means includes at least one modem for communicating a software upgrade to at least one of said selected cable locating transmitters.

8. The apparatus according to claim 6 further including a store and forward apparatus for communicating said software upgrade to all of said selected cable-locating transmitters.
