DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a duplex information transmitting apparatus, and more particularly to a duplex information transmitting apparatus which inputs the same data from different input points and outputs predetermined information contained in these data from different output points. Information transmission device.

[0002]

2. Description of the Related Art Conventionally, this type of duplex information transmission device has
It is used to transmit the input data irrespective of the state of the apparatus and to always output it.

[0003] Referring to FIG. 2 which is a block diagram of the conventional duplex information transmitting apparatus, the conventional duplex information transmitting apparatus, when there is information destined for a computer in data received from a terminal device. Is transmitted to the computer, and when there is no information for the computer in the received data, the data is notified to the other system as data for the other system (not shown). Contains information intended for a computer, this information is output to the first computer 10 (having a first information exchange unit 14 and a first data processing unit 15).
When the data received from the second terminal device 9 and the data includes information for a computer, the information is output to the second computer 11 (the second information exchange unit 16 and the second information exchange unit 16). And a second information transmission device (which has two data processing units 17).

[0004] The first terminal device 8 and the second terminal device 9 provide respective information (for example, temperature information, humidity information, pressure information, etc. in the case of meteorological information; If it is related, traffic information, traffic congestion information, accident information, etc.) are respectively managed, and in order to notify a computer or the like that needs this information, the 1-system information transmission of the duplex information transmission device is performed at a predetermined cycle. The notification is simultaneously made to the unit 12 and the second system information transmission unit 13 respectively. The first terminal device 8 and the second terminal device 9 receive the same information from a plurality of observation devices,
The same data (including at least one or more pieces of information to which a notification destination address (for example, an address indicating a computer) is added) to the first-system information transmission unit 12 and the second-system information transmission unit 13
Is notified at a predetermined cycle. A serial number is added to this data (the same number is assigned to the same data), and the serial number is 1
The numbers up to N (for example, 256) are the circulation values.

[0005] The first information exchange unit 14 receives data from the first terminal device 8 and transmits the data to the second information exchange unit 1.
Notify 6. Then, whether or not this data is newly received data is checked by the serial number added to this data,
If the data is not newly received data, the data is discarded. If the data is newly received, the "destination address" added to each of a plurality of pieces of information included in the data is checked, and the address indicating the address for the computer is indicated. When there is at least one piece of information to which the "notification address" is added, this data is notified to the first data processing unit 15 as data for a computer. Further, the data is received from the second information exchange section 16, and it is checked whether or not the data is newly received data. If the data is not newly received data, the data is discarded. When there is information for a computer among a plurality of information included in this data, the data is notified to the first data processing unit 15. The second information exchange unit 16 operates in the same manner as the first information exchange unit 14 described above. However, the first is the second and the second is the first
To read.

[0006] The first data processing unit 15 receives data from the first information exchange unit 14 and notifies the second data processing unit 17 of the data. Then, whether or not this data is newly received data is checked based on the serial number added to the data. If the data is not newly received data, this data is discarded. If it is newly received data, the computer included in this data is discarded. Information with an address for
To the computer 10. Also, the second data processing unit 1
7 to check whether this data is newly received data, and discard if it is not newly received data,
When the data is newly received, the information to which the address for the computer included in the data is added is notified to the first computer 10 as described above. Second data processing unit 17
Performs the same operation as the first data processing unit 15 described above. However, the first is read as the second and the second as the first.

The first computer 10 and the second computer 11 respectively accumulate the notified information, perform statistical processing such as averaging and summing, and output the result to a CRT, a printer, or the like.

As a result, even if either the terminal device and / or the information exchange unit or the data processing device and / or the computer of one of the systems 1 and 2 is stopped, the input is performed. The information for the computer can be output to the computer.
