Abstract

PURPOSE:To obtain a memory which requires no address by circulating data through a looped transmission line and reading them at need, erasing data having a low frequency of utilization, and transferring data having high frequencies of utilization to another loop and retaining them. CONSTITUTION:Loop transmission lines 1 and 2 where data to be stored are circulated, transmission controllers 11-13, and 21-28 of the same constitution on the transmission lines, and controllers 31-33, and 41-45 which send processed data to the loops and read data from the loops are connected together by two- way transmission lines 51-53, 61-63, and 71-75, and are connected to an external circuit which is not shown in the figure by two-way transmission lines 81-85. The controllers 41-45 process and retain external data on the loop 2, or send out the data externally. The controllers 31-33 transfer the most important data among data on the loop 2 to the loop 1, and retain the data on the loop. Unnecessary data among the data on the loop 2 are erased. Thus, a memory which requires no address is constituted.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an information electric field system, and more particularly, to an information electric field system that can store and output information without using addresses, and that can naturally erase unnecessary information while leaving important information. This is related to the buried system AK.

When it comes to remembering information, information that is frequently used is stored for a long time, and conversely, information that is no longer used is deleted, so that the information that is generated one after another can be stored within the limited capacity of the storage medium. This is necessary.

Also, when using news reports, you can get where the information is stored in order to simply escape.

It is hoped that it can be brought out even if it is not there.

Conventionally, magnetic storage media have been used to store information, but these have a fixed storage location, and in order to write information one after another, the location must be known in advance. That's fine then. Also, once you memorize something, it won't gradually fade unless you turn off the power or erase the information all at once. For this reason, as the amount of information increases, when used by a number of processors,
Management of information storage addresses, writing of information, continuous output O
The drawback is that the management of the Gua Setsuna OiI Association is complicated. In addition, when deleting information, it is necessary to manage each piece of information as to when to delete it, so as the amount of information increases, the memory of the person becomes enormous and complicated. there were.

The present invention solves the drawbacks of the prior art by using a data transmission line as a storage medium, and after transmitting data onto this transmission line, the data is passed around as it is, and if necessary, an address can be specified. I turned around without doing anything and pulled out the data again.
And while the data is returning () on the transmission path,
New information processing that allows data that is less frequently used to be deleted gradually, and that can easily control the period until data is deleted by changing the transmission route for transmitting the data (depending on the content and importance of the data) system.

Hereinafter, the present invention will be explained based on Examples.

FIG. 1 shows the overall configuration of an information storage system according to the present invention. This system consists of data to be stored t, storage loop transmission lines 1 and 2, which are connected to loops made in the same structure. Multiple transmission control devices 11.12.13
．． and 21 to 28, a control device si for sending processed data to a loop transmission path and processing data read from the loop transmission path, 32.33 and 41 to 45, a pair of transmission control device and control device; Bidirectional transmission line 5 to connect
1 to 53, 61 to 63, 71 to 75, and bidirectional transmission lines 81 to 85 that are T-connected to the control device and external terminal equipment (not shown). Here, the control devices 31 to 33 will be referred to as level I control devices, and the control devices 41 to 45 will be referred to as level 20 control devices. The level 2 control devices 41 to 45 process the data collected from the first external terminal device, and send the data to the loop 2 transmission control devices 21 to 25 to store the results. It also collects and processes necessary data from the t-memory loop 2, and sends the results to an external terminal device. On the other hand, the control devices 31 to 33 at level i
From the data flowing above, important data and other data that need to be stored for a long time are selected, collected and processed, and the results are sent to the storage loop l.

The control devices 31-33, 41-45 transmit necessary data to the control devices 11-13'! The good method will be explained using Figures 2 to 5.

FIG. 2 shows the format 10G of the message flowing on loop 1.2. Message lo.

consists of a content code 12Q indicating the content of the start flag 110% end flag 1401 data, and each field of data 130. Content code 1! ! O is 1 data 13
It is attached by the control devices 31 to 33 and 41 to 45 that generated the zero. Each transmission control device 11-13 and 21-28 looks at the content code 120 of the message 100 flowing through the loop and determines whether or not to receive it. Which content code a transmission control device should receive depends on the content code registered in advance in a table within each transmission control device from the corresponding control device. The loops performed by each control device, the transfer of data from external terminal equipment, and the registration of content codes to the transmission control device are as follows.

No. Him shows one control device, for example, a 41oA physical structure. This device consists of a processing device 40G, an interface 41G with the transmission control device 21, and an interface 4s6 with the terminal device. level l
In the case of the control device, the interface 420 becomes a connection interface with the transmission control device on the loop 2 side.

The processing device 400 has a memory, which includes a first receiving buffer 43o1 for storing received data from the interface 410 side, a second receiving buffer 440 for storing received data from the interface 420 side, and a first receiving buffer 440 for storing received data from the interface 420 side. A first content code table 450 stores the content code of data to be received from the x410111, a second content code table 460 stores the content code of data to be received from the interface 420%, and stores data to be sent to the interface 410 side. It constitutes a first transmission buffer 470 and a second transmission buffer 480 that stores data to be sent to the interface 420 side.

The control device 41 sends the first content code table 45G to the transmission control device 2 via the data layer interface 410 when the power is turned on or when there is a change in the content code of the data to be received. If the level 1 control device %fI1 is, for example, 31, the data of the 1a2 content code table 460 is further sent to the other transmission control device 28 via the interface 420.

The content code of the message to be received sent from the control device 41 is written into the content code entry table 27Q in the transmission control device 21 shown in FIG. If the content code 12G of the message 100 received from the walking group 2 matches any of the codes registered in the content reading table 27G, the transmission control device 21 takes in the received message and sends it to the control device via the interface 290t. 41
send to the side. A message received from the transmission control device 21 into the control device 41 via the interface 410t is stored in the first receiving buffer by the first processing device 400. On the other hand, outside s11! Nine messages received from the II terminal device (in the case of level 1, the other transmission control device) via the interface 4201 are stored in the first and third reception buffers. The processing device includes a first receiving buffer 430, a second receiving buffer 430,
When a message is stored in 44G, it is processed according to the content code and data, and then stored in buffers 430 and 440.
Delete the corresponding message in . The data processing results are
Depending on the direction to be transmitted, the signals are stored in the first or second transmission buffer 470, 480, respectively. When there are messages in the first and second transmission buffers 470 and 480, the processing device 400 transmits these messages through the interfaces 410 and 420, respectively, and then sends them to the buffer 47.
Delete the corresponding message within 0.48g.

Next, how is the message sent from the control device sent onto the loop within the transmission control device? How is the data on the loop taken into the transmission control device?
How to transfer the data onto the loop and how to erase unnecessary data will be explained using FIG. 4 showing the configuration of the transmission control device. Furthermore, all the transmission control devices 11 to 13 and 21 to 2B have the same configuration],
ζζ will be explained using the transmission control device 21 as an example.

The message sent from the loop 2 is sent via the interface 210 to an amplitude detection device 220 for measuring the signal amplitude of the message and to a second receiving node (transfer 3sO) for temporarily storing the message. The message that has passed through the m-width detection device 220 is stored in the first reception buffer 23G.The transmission control device 21 receives the message sent from the processing device 200 and the control device 41 that control the entire system of the device.

Note that in FIG. 1, the control signal 310°8 from the 1 interface 210°290 to the processing device 200 is
A control signal 3301 outputted from the IAm station 2GG to a rounder controlling x each y 300tlllL 3301 loop 2 receives and informs the amplitude of the nine signals from the amplitude detecting device 22G to the signal attenuation device 360, amplitude detecting device A control signal 38G for activating is indicated by a dotted line.

The operation within the transmission control device 21 is as follows.

When a message is sent from loop 2, interface 21G sends this message to amplitude detector 22G and a second receiving buffer. In this case, interface 21G has 7 lags 11G and 14 in message 100.
G is detected and at 9 o'clock, a control signal 310t indicating that a message has been received and that message reception has been completed.
Output. When the processing device 200 learns that the signal has been received by the control signal 31G, the processing device 200 detects the amplitude detection device 220.
Activate. The amplitude detection device 220 measures the amplitude of the received signal, sends a signal indicating the measured value to the signal attenuation device 240, and stores and processes the message in the first receiving buffer 7280. 20G is the message 10 stored in the first or second receiving pazza.
The content code 12G of G is the content code registration table 270
The message is checked to see if it is already registered, and if it is, the message is imported.
The message in the first reception buffer is deleted. When receiving the signal 31 (l) indicating the end of the message from the interface 210, the processing device 20G sets the message sending check timer (T,) 3170-. On the other hand, when a message is sent from the control device 41 to the interface 290 via the data block 1, a signal 32G is sent from the interface 29G to the processing device 200 indicating the start and end of reception of the message.
is emitted. At this time, interface 29G sends the received message to transmission buffer 28G.

The processing device 200 processes the second reception buffer a! When a message is received in so, if the message is to be received, it is sent to the control device 4 via the interface 29G.
1, and in response to the above-mentioned exit message during the second reception buffer, a flyer flag indicating the end of transmission is set in the 979 tag area. If there is a message in the transmission buffer 280, the processing device 20G sends this message to loop 2.

Regarding the message in the second reception buffer 250, when the value of the transmission check timer ('rt) 37G becomes equal to or greater than the predetermined value T@sag, a transmission end flag is already set in the second reception buffer 250. The one for which is set is sent onto loop 2. Message transmission in the second receiving buffer is as follows:
This is done after all messages in the sending buffer 28G have been sent. After sending the message in the second receiving buffer, if there is a message in the first buffer, it is sent. When the processing device 200 sends messages in the transmission buffer 28G or the second reception buffer 25G to the loop 2, the processing device 200 transmits these messages to the signal reproducing device 260.
At the same time, a control signal 330 is generated to connect the selector switch 300 to the terminal 35G side. Well, mourning.
When transmitting the message in the first receiving buffer, the message is output to the signal attenuator 24G, and a control signal 330 is generated to connect the first selector switch aoot to the terminal 340 side. When the message has been sent onto the loop 2, the processing device 20G erases the sent message from each buffer 280, 250, 230, and sets the message sending check timer 3 corresponding to each message.
Reset 70.

The W&@ conversion of the signal by the signal attenuation device 2401 and the signal regeneration device 260 will be explained with reference to FIGS. 5 and 6, respectively.

Now, the signal inputted by the loop is sent to the amplitude detection device 220.
It is assumed that the amplitude value is detected as A-. as shown in FIG. 5(A). The signal attenuation device 24G multiplies the input signal by a predetermined attenuation rate r3, converts it into a signal with an amplitude A11AH=Ass' 1m, and sends out the signal, as shown in FIG. 5(B). Now, assuming that the signal amplitude of the message when it is first sent onto the loop is the signal attenuation rate tα between each transmission control device in AH1, the n transmission control devices always pass through the signal attenuation device 240 to save the transmission. The amplitude A of the message sent to the channel is A=Asl (1-ndrm). Therefore, if the threshold value tA of the amplitude that allows interface 21 (l(No. 1) to be recognized is A It will be considered as such and will be deleted.

On the other hand, the signal reproducing device 260 converts this into the initial attribute shown in FIG. 6(B) regardless of the amplitude of the input signal from the loop shown in FIG. 6(A) (where A□≧X). It reproduces and outputs a signal with an amplitude of -8.

From the above, unless a message on the loop is received by the transmission control device and taken in by the control device, the K11 width attenuates every time it passes through the transmission control device and naturally disappears during transmission. However, messages that are received repeatedly are stored in a loop for a long period of time, with the amplitude of the signal being regenerated by the transmission control device each time the message is received.

In the above system, important information among the information flowing through loop 2 is stored on loop 1, and the number of transmission control devices connected to loop 1 is made smaller than the number of transmission control devices connected to loop 2. ~ and the loop (if the attenuation rate r□ of the signal attenuation device 240 in each transmission control device above is made smaller than the signal attenuation device r2 of the transmission control device on loop 2, the message storage on loop 21 The period can be longer than the message storage period on loop 2.

When the level 2 control devices 41 to 45 require a message with a certain content code PCI, and the message cannot be found on loop 2 even after waiting for a certain period of time, the transmission control devices 21 to 2s is its content code Pc
The request may be made to one of the transmission control devices 26 to 28 via the message t-request 1 loop 2 for the message t.

Now, assuming that the transmission control device 26 is in charge of the content code FCz, the transmission control device 2- registers the code Fc1 in the content code registration table 270 of the transmission control device 13 via the control device 33. If content code F on loop 1
If there is a message of C1, this message is read out onto the loop 2 via the transmission control device 13, the control device 33, and the transmission control device 26t, and sent to any one of the requesting message t via the transmission control devices 21 to 25. Control device 41~
Incorporated into 4s.

As is clear from the above description, according to the information processing system of the present invention, it is possible to store and read messages without knowing the message storage address, and messages that are frequently used or highly important are stored for a long period of time. Deki 1 conversely 1
The amount of data accumulated can be controlled by allowing messages with low usage or importance to disappear naturally.
