Abstract

An armament system for use with a plurality of different types of stores, and comprising a central unit and a plurality of distributed stations. The central unit holds a plurality of store specific application programs, and each of the plurality of store types is associated with one of the store specific application programs. Moreover, each of the store specific application programs is adapted to control the transmission of data between a store of an associated type and one of the distributed stations. The central unit is adapted to control the operation of the armament system and the transmission of data between the central unit and the distributed stations, and to transmit any of the store specific application programs to any of the distributed stations of the armament system.

Claims

1. A data management system for use with a plurality of different types of stores, the data management system comprising:

a central unit;

a plurality of distributed stations; and

means to transmit data between the central unit and the distributed stations;

the central unit including

(i) means to hold a plurality of store specific application programs, each of the store specific application programs being associated with one of the plurality of store types, each of the store specific application programs including means to control the transmission of data between a store of an associated type and one of the distributed stations, and

(ii) means to control the operation of the data management system, and including means to select any of the store specific application programs for transmission to any of the distributed stations of the data management system;

each of the distributed stations including

(i) means to connect the station to one store of any of said store types,

(ii) an input-output section to transmit data between the station and said one store that is connected to the station, and

(iii) means to hold any one of the store specific application programs.

2. A data management system according to claim 1, wherein each distributed station further includes a store generic application program to control the transmission of selected data between the station and a store of any of said plurality of types of stores that is connected to the station.

3. A data management system according to claim 2, wherein:

each of the distributed stations further includes a store interface unit connected to the input-output section of the station to receive data from and to transmit data to the input-output section of the station;

the store generic application program is held in the store interface unit; and

the means to hold the store specific application program is also located in the store interface unit.

4. A data management system according to claim 3, wherein each store generic application program includes:

means to determine if a store is attached to the station in which the store generic application program is located; and

means to determine the type of store attached to the station in which the store generic application program is located.

5. A data management system according to claim 4, wherein each store generic application program further includes means to generate and send to the central unit a store present signal indicating that a store is attached to the station in which the generic application program is stored, and identifying the type of said store.

6. A data management system according to claim 5, wherein, in response to receiving the store present signal from one of the distributed stations, the central unit sends to said one distributed station, the store specific application program associated with the type of store connected to said one distributed station.

7. A data management system according to claim 6, wherein each store specific application program includes:

means to determine if a store is attached to the station in which the store specific application program is located; and

means to determine if a store attached to the station is of the type associated with the store specific application program.

8. A data management system according to claim 1, wherein:

the means to transmit data between the central unit and the distributed station includes a system data bus connected to the central unit and to each of the distributed stations;

each distributed station further includes

(i) a bus interface unit connected to the system data bus to transmit data between said system data bus and the distributed station, and

(ii) a store interface unit connected to the bus interface unit and to the input-output section of the station, to receive data from and to transmit data to the bus interface unit, and to receive data from and to transmit data to the input-output section of the station.

9. A data management system according to claim 8, wherein:

each distributed station further includes a store bus connected to the bus interface unit of the station, to directly connect the bus interface unit to the store connected to the station; and

each distributed station has a normal mode of operation to transmit data between the bus interface unit and the store interface unit of the station, and a bypass mode of operation to transmit data between the bus interface unit and a store connected to the station.

10. A data management system according to claim 9, wherein:

the central unit further includes means to generate a passthrough command and to send the passthrough command to the bus interface units; and

each bus interface unit includes a control program including means, responsive to the passthrough command, to change the bus interface unit from the normal mode of to the bypass mode of operation.

11. A data management system according to claim 1, wherein:

the means to transmit data comprises first and second system data buses, each of the system data buses being connected to the central unit and to each of the distributed stations; and

each distributed station further includes

(i) first and second bus interface units, the first bus interface unit of each distributed station being connected to the first system data bus to transmit data between the distributed station and the first system data bus, the second bus interface unit of each distributed station being connected to the second system data bus to transmit data between the distributed station and the second system data bus, and

(ii) first and second store interface units, the first store interface unit of each distributed station being connected to both the first and second bus interface units of the station to transmit data between said first store interface unit and the first and second bus interface units of the station, the second store interface unit of each distributed station being connected to both the first and second bus interface units of the distributed station to transmit data between the second interface unit and both the first and second bus interface units of the station.

12. A data management system according to claim 11, wherein:

each distributed station further includes first and second store buses;

the first store bus of each distributed station is connected to the first bus interface unit thereof to transmit data directly between said first bus interface unit and a store connected to the station; and

the second store bus of each distributed station is connected to the second bus interface unit thereof to transmit data directly between said second bus interface unit and the store connected to the station.
