Remote control and data logging system

Claim 2

A teleprinter remote control and data reporting system comprising: a control station having means for transmitting and receiving teleprinter signals; at least one outstation having means for transmitting and receiving teleprinter signals, said receiving means including means responsive to a selected teleprinter call character for opening said outstation to a command signal from said control station whenever said selected teleprinter call character is received by said outstation for a predetermined number of times in succession, and said transmitting means including means for transmitting a predetermined teleprinter acknowledgment character whenever said selected teleprinter call character has been received by said outstation for said predetermined number of turns in succession; and, a communication channel connecting said control station and said outstation.

Claim 3

The system of claim 1 further characterized by said outstation including means operative whenever said outstation is open for transmitting reporting date in teleprinter code to said control station in response to a report command teleprinter signal from said control station.

Claim 4

The system of claim 2 wherein said reporting data transmitting means comprises: report shift register means for commutating the report data from a plurality of data sources; control means for said report shift register means; means for producing a predetermined teleprinter character in parallel form whenever the binary value of the reporting data is ''''1'''' and a different predetermined teleprinter character whenever the binary value is ''''0''''; transmitted signal shift register means for converting the parallel teleprinter character from said character-producing means into serial form for transmission over said communication channel; and control means for said transmitted signal shift register means.

Claim 5

The system of claim 1 further characterized by means operative whenever said outstation is open for actuating a selected remote control function in response to a remote control teleprinter command signal from said control station.

Claim 6

The system of claim 4 further characterized by means for acknowledging receipt of said remote control command signal before said remote control function is actuated.

Claim 7

The system of claim 5 further characterized by means for acknowledging the actuation of said remote control function.

Claim 8

A teleprinter remote control and data reporting system comprising: a control station having means for transmitting and receiving teleprinter signals; at least one outstation having means for transmitting and receiving teleprinter signals, said receiving means including means responsive to a selected teleprinter call character or opening said outstation to a command signal from said control station whenever said selected teleprinter call character is received by said outstation for a predetermined number of times in succession; said transmitting means including means operative whenever said outstation is open for transmitting reporting data in teleprinter code to said control station in response to a report command teleprinter signal from said control station, report shift register means for commutating the report data from a plurality of data sources; control means for said report shift register means; means for producing a predetermined teleprinter character in parallel form whenever the binary value of the repOrting data is ''''1'''' and a different predetermined teleprinter character whenever the binary value is ''''0''''; transmitted signal shift register means for converting the parallel teleprinter character from said character-producing means into serial form for transmission over said communication channel; and control means for said transmitted signal shift register means; and a communication channel connecting said control station and said outstation.

Claim 9

A teleprinter remote control and data reporting system comprising: a control station having means for transmitting and receiving teleprinter signals; at least one outstation having means for transmitting and receiving teleprinter signals, said receiving means including means responsive to a selected teleprinter call character or opening said outstation to a command signal from said control station whenever said selected teleprinter call character is received by said outstation for a predetermined number of times in succession; said transmitting means including means operative whenever said outstation is open for transmitting reporting data in teleprinter code to said control station in response to a report command teleprinter signal from said control station, report shift register means for commutating the report data from a plurality of data sources; control means for said report shift register means; means for producing a predetermined teleprinter character in parallel form whenever the binary value of the repOrting data is ''''1'''' and a different predetermined teleprinter character whenever the binary value is ''''0''''; transmitted signal shift register means for converting the parallel teleprinter character from said character-producing means into serial form for transmission over said communication channel; and control means for said transmitted signal shift register means; and a communication channel connecting said control station and said outstation.

Claim 10

The teleprinter remote control and data reporting system of claim 7 wherein said transmitting means further includes means for transmitting a predetermined teleprinter acknowledgment character whenever said selected teleprinter call character has been received by said outstation for said predetermined number of times in succession.

Claim 11

The system of claim 8 further characterized by means operative whenever said outstation is open for actuating a selected remote control function in response to a remote control teleprinter command signal from said control station.

Claim 12

The system of claim 9 further characterized by means for acknowledging receipt of said remote control command signal before said remote control function is actuated.

Claim 13

The system of claim 10 further characterized by means for acknowledging the actuation of said remote control function.
