Abstract

PURPOSE:To considerably shorten the working time required for setting operating control information and to attain the setting of operating control information with an existing MODEM without provision of other MODEM by setting the operating control information to a deputy MODEM automatically. CONSTITUTION:It is explained as an example as the operation that only one MODEM 1(n) is not in use among MODEMs 1(1)-1(n) and the MODEM 1(1) enters function stop state. That is, as soon as the MODEM 1(1) is stopped, the monitoring section 5(1) of the MODEM 1(1) detects the function stop state and a readout signal (a) and a transmission signal (b) are outputted respectively to a storage section 3(1) and a transmission/reception section 4(1). An operation control signal (c) obtained thereby is received by a reception section 6, from which signals (d), (e) and (f) are transmitted respectively to a selection section 7, a switching section 8 and a transmission section 9. Then the signal (c) from the transmission section 9 is given to the MODEM 1(n) of the same constitution and the operation is kept entirely the same as the operation of the MODEM 1(1) and the MODEM 1(n) is used in place of the MODEM 1(1).

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a collective data transmission device, and in particular, to automatic setting of operation control information of a modulation/demodulation device in a malfunctioning state to a normal modulation/demodulation device in an inactive state. The present invention relates to a collective data transmission device that can transmit data.

[Conventional technology]

In conventional collective data transmission equipment, when switching operation control from a modem that has stopped functioning to a replacement modem, the same operation control information as that of the modulation and demodulation that has stopped functioning is transferred to the replacement modulation and demodulation. It was set. Alternatively, instead of setting the operation control information each time, a method has been adopted in which a modem with operation setting information set in advance is prepared separately, and the modem is switched to the prepared modem when the function stops.

[Problems to be Solved by the Invention] In the conventional collective data transmission device described above, when one of the plurality of modems stops functioning, a substitute modem is used to replace the one that has stopped functioning. Since it is necessary to set operation control information to perform the same operation as the modulation/demodulation device, there is a drawback that a long time is required for the setting work. Furthermore, the method of preparing a separate modulation/demodulation device has the drawback of requiring a large amount of expense for manufacturing or purchasing the separate modulation/demodulation device.

SUMMARY OF THE INVENTION An object of the present invention is to provide a collective data transmission device that solves the above-mentioned conventional problems and automatically sets operation control information to reduce setting time and cost.

[Means to solve the problem]

The present invention provides a collective data transmission device that includes a plurality of modems and a control device that controls them, and that transfers operation control information of a modem that has stopped functioning to other modems that are in an inactive state. Each of the modulation/demodulation devices includes a storage unit that stores operation control information, and a storage unit that transfers the operation control information in the storage unit to the control device when the function is stopped, or receives operation control information from the control device when it is not in operation. a transmitting/receiving unit storing the information in a storage unit, and the control device includes a selecting unit that receives the operation control information transferred from the modem and selects the modem that is in an inactive state; and a switching section that switches the selected modem to an operating state and transfers the operation control information received by the selection section to the selected modem.
