It was delivered to _m (m, m ₁ , m ₂ , n, n ₁ , n ₂ , s, t are natural numbers).

[Problems to be Solved] However, in the conventional information collection and delivery system, for example, in the case of FIG. 5, information can be collected and delivered simultaneously and in parallel without causing traffic congestion on the transmission path, and the system is designed without the need for address information. Or, maintenance was easy, but there are mn transmission lines (for example, when m = 20, n = 100, mn = 2000).
However, if the information collecting device and the information processing device are located remotely from each other, there is a drawback that the installation thereof requires a great deal of expense.

Further, in the case of FIG. 4, the total number of transmission lines can be compressed by reducing the installation cost by sharing the transmission lines, and the drawback of FIG. 5 can be solved, but it is necessary to add address information to each information packet signal. However, even if it is possible to operate by balancing the flow rate of information packet signals in general use, there is a drawback that system design or maintenance becomes complicated When applied to a large system such as a power system monitoring and control system that requires the transfer of a large amount of information to and from each other, a large number of information detection devices operate simultaneously due to a wide-range power outage, etc. When a large amount of packet signals are concentrated on the exchange, there is a drawback that information congestion occurs and it is difficult to respond flexibly.

Therefore, the present invention solves these problems at the same time, does not cause information congestion on the transmission path, requires almost no information address management, simplifies the transmission path, and facilitates system design and maintenance. The purpose is to provide a computerized information collection and delivery system.

(2) Structure of the Invention [Means for Solving the Problems] The solution provided by the present invention collects information from a specific large number of information sources and delivers it to a specific large number of delivery destinations that need the information. An information collecting and delivering system for collecting information from the delivery destination and transmitting the information to each of the specific large number of information sources, comprising: (a) a plurality of information sources allocated to each of the information source and the delivery destination. A storage device having a storage area, and (b) each of the information sources is connected via a transmission line, and the information collected from the information sources is written in a corresponding storage area of the storage device, and the storage area A first plurality of information writing / reading devices for reading information written in the delivery destination from the delivery destination and transmitting the information to the information source; (c) connected to each of the delivery destinations via a transmission line; Said delivery A second plurality of information writing / reading devices for writing the information collected from the storage device in a corresponding storage area of the storage device and for reading the information written in the storage area from the information source and transmitting the information to the delivery destination. And (d) a storage area allocated to each of the first information writing / reading device and the second information writing / reading device and each of the information source and the delivery destination in the storage device. An information collecting and delivering system, characterized in that it comprises a timing means for connecting between the units periodically and for a fixed time.

Is.

[Operation] In the information collecting and delivering system according to the present invention, the timing means causes each of the first information writing / reading device and the second information writing / reading device, and each of a large number of specific information sources and delivery destinations in the storage device. Is connected to the storage area allotted with respect to each other at regular time intervals. As a result, the information (for example, the open / closed state of the electrical contacts) from a specific large number of information sources (for example, the transmission / substation) is periodically stored in the plurality of corresponding storage areas of the storage device by the first plurality of information writing / reading devices. The information from the written information sources is read by the second plurality of information writing / reading devices in a time division manner and then transmitted to each delivery destination (for example, a power supply station). At the same time, information (for example, voltage and power information) from a specific number of delivery destinations (for example, a power supply station) is periodically written into a corresponding number of storage areas of the storage device by the second plurality of information writing / reading devices. Then, the written information from the delivery destinations is read by the first plurality of information writing / reading devices in a time division manner and then transmitted to each information source.

Due to such an action, in the information collecting and delivering system of the present invention,
Between a specified number of information sources and a specified number of delivery destinations,
Information is bidirectionally and time-resolved.

Moreover, both the information source and the delivery destination are set to a specific large number, the total number is known in advance, and since the information is transmitted periodically and within a fixed time, a large number of each information arrive at the same time. However, it will always be delivered within a fixed time, which prevents the delay of collection and delivery due to the concentration of information, and can significantly reduce the address management of information, and greatly increase the amount of work for information collection and delivery. Can be reduced.

Hereinafter, the above operation is repeated.

As described above, in the information collecting and delivering system 10 of the present embodiment, the information detecting devices 18 ₁ , ..., 18 _{m serving} as a specific large number of information sources and the information processing devices 26 ₁ , ..., 26 _{n serving} as a specific large number of delivery destinations are provided. During this period, information is bidirectionally transmitted, and transmission switching of these information is performed in a time division manner. Therefore, according to the above-described example, it is possible to promptly select and send out the required amount of recent information between the power generation / substation and the power feeding station.

Here, in this embodiment, since both the information source and the delivery destination are set to a specific number, the total number is known in advance, and moreover, the information writing / reading devices 14 ₁ , ..., 14 _m and 24 _m
Since the processing times of ₁ , ..., 24 _n are constant, it is possible to set a timer device 18, which will be described later, as a timing means to a constant time. For example, if you set the cycle to 1 second,
Every 1 second, new information will be sent from the transmission / substation to each substation, and from each substation to the substation / substation.

Further, by writing all necessary information of the transmission / substation and the power supply station in the memory device 12, even if a large-scale accident occurs and the information changes, the information bit changes from "0" to " Since the total amount of information does not change since it only changes from "1" or from "1" to "0", delay in transmission of information does not occur.

Next, the configuration and operation for writing information to and reading information from the storage device 12 will be described in more detail regarding the information collection and delivery system 10 shown in FIG. 1 (see FIGS. 2 and 3).

Address signal S output from the timer device 18 to the bus 20
Of the address "A ₁₁ " (for example, "001" in binary notation) of the information writing / reading device 14 ₁ , the strobe signal ST output from the timer device 18 to the strobe line 22 is
It goes from high level or "1" to low level or "0".

Thus the information writing reading device 14 ₁ operates as follows.

That is, since the content of the address signal S output from the timer device 18 matches the address "A ₁₁ " of the information writing / reading device 14 ₁ , the output of the address decoder 14 ₁₄ changes from high level, that is, "1" to low level, that is, It becomes "0". Therefore inverting the NAND circuit 14 _13, its output is changed from the high level or "1" to a low level or "0".

As a result, an interrupt signal is given from the interrupt controller unit 14 ₁₂ to the central processing unit 14 ₁₁ , and the central processing unit 14 ₁₁ is connected to the storage device 12 via the bus 16. The central processing unit 14 ₁₁ has a storage area 12 ₂₁ updates the held data writing new data to the storage area 12 ₁₁ of the storage device 12, and the storage device 12, 12 _22, ..., to itself from 12 _2n Read the required data.

The information writing / reading devices 14 ₂ , ..., 14 _m ; 24 ₁ , ..., 24 _n operate as follows.

That is, the content of the address signal S output from the timer device 18 is the address "A ₁₂ ", ..., "A _1m ";"A _{21 of the} information writing / reading device 14 ₂ , ..., 14 _m ; 24 ₁ , ..., 24 _n. ", ...," A _2n "does not match, so the address decoder 14 ₂₄ , ..., 14 _m4 ; 24 ₁₄ , ..., 24 _n4
Has all its outputs maintained high, or "1". Therefore, even if the strobe signal ST changes from the high level, that is, "1" to the low level, that is, "0", the output of the inverting NAND circuit 14 ₂₃ , ..., 14 _m3 ; 24 ₁₃ , _,,, 24 _n3 is high level, that is, "1". It remains maintained at ". Therefore, the interrupt controller unit 14 ₂₂ , ..., 14 _m2 ; 24 ₁₂ , ..., 24 _n2 does not give an interrupt signal to the central processing unit 14 ₂₁ , ..., 1 _m1 ; 24 ₁₁ , ..., 24 _n1 , Central processing unit 14 ₂₁ , ..., 14 _m1 ; 24 ₁₁ , ..., 24 _n1 is bus 1
Not connected to 6. Therefore, the information writing / reading device 14 ₂ , ..., 14
_m ; 24 ₁ , ..., 24 _n continues its own arithmetic operation.

When the time allotted to the information writing / reading device 14 ₁ has passed, the contents of the address signal S output from the timer device 18, that is, the content of the address signal S output from the timer device 18, is changed to the information writing / reading device 14 ₂ , ..., 14 _m ; 24 ₁ , ..., 24 _n address "A ₁₂ ", ..., "A
_1m ";" A ₂₁ ", ...," A _2n "does not match, so the output of address decoder 14 ₂₄ , ..., 14 _m4 ; 24 ₁₄ , ..., 24 _n4 is all high level, that is," 1 " Therefore, even if the strobe signal ST changes from the high level, that is, "1" to the low level, that is, "0", the inverting NAND circuits 14 ₂₃ , ..., 14
_m3; 24 _13, ..., remains an output of 24 _n3 which is maintained at a high level or "1". Therefore, the interrupt controller unit
14 ₂₂ , ..., 14 _m2 ; 24 ₁₂ , ..., 24 _n2 is the central processing unit 14 ₂₁ , ..., 14
_m1; 24 _11, ..., without giving an interrupt signal to the 24 _n1, the central processing unit _{14 21, ..., 14 m1;} 24 11, ..., 24 n1 is not connected to the bus 16. Therefore, the information writing / reading device 14 ₂ , ..., 14 _m ; 24 ₁ , ..., 24 _n
Continues its arithmetic operation.

When the time allotted to the information writing / reading device 14 ₁ has elapsed, the content of the address signal S output from the timer device 18 is removed, that is, the address “A ₁₁ ” to “0” of the information writing / reading device 14 _1. (For example, "000" in binary notation), and the strobe signal ST is changed from low level or "0" to high level or "1".

Thus the information writing reading device 14 ₁ operates as follows.

That is, since the content of the address signal S output from the timer device 18 does not match the address "A ₁₁ " of the information writing / reading device 14 ₁ , the output of the address decoder 14 ₁₄ changes from low level, that is, "0" to high level, It becomes "1". Therefore inverting the NAND circuit 14 _13, its output is low or "0"
Is changed from high level to “1”.

As a result, the interrupt signal given to the central processing unit 14 ₁₁ from the interrupt controller unit 14 ₁₂ is removed, and the connection of the central processing unit 14 _{11 to} the bus 16 is cut off.

Information writing reading device 14 _1, thereby is interrupted connection to the storage device 12, transmission of message information from its own calculation work for example information collection execution control device 16 ₁ for receipt or information collection execution control apparatus 16 _first data information Resume work.

The information writing / reading device 14 ₂ , ..., 14 _m ; 24 ₁ , ..., 24 _n operates as follows.

That is, the content of the address signal S output from the timer device 18 becomes "0" (for example, "000" in binary notation), and the address "A" of the information writing / reading device 14 ₂ , ..., 14 _m ; 24 ₁ ..., 24 _{n. 21} ", ...,
"A _m1 ";"A ₁₂ ", ..., "A _n2 " still do not match, so the outputs of the address decoders 14 ₂₄ , ..., 14 _m4 ; 24 ₁₄ , ..., 24 _n4 are all high level, ie "1". "Is maintained. Therefore, even if the strobe signal ST changes from the low level, that is, "0" to the high level, that is, "1", the inverting NAND circuit 14
The output of ₂₃ , ..., 14 _m3 ; 24 ₁₃ , ..., 24 _n3 remains high level or "1". Therefore, the interrupt controller unit 14 ₂₂ ,, 14 _m2 ; 24 ₁₂ , ..., 24 _n2 is the central processing unit 14
₂₁ , ..., 14 _m1 ; 24 ₁₁ , ..., 24 _Do not give an interrupt signal to _n1 ,
The central processing units 14 ₂₁ , ..., 14 _m1 ; 24 ₁₁ , ..., 24 _n1 are not connected to the bus 16. Therefore, the information writing / reading device 14 ₂ , ..., 14 _m ; 2
4 ₁ , ..., 24 _n continue their own arithmetic operations as described above.
