Description

[Detailed Description of the Invention] [Summary] In a communication network device in which a network control device receives data from a plurality of terminals by polling and transmits this data to a receiving terminal at the time of polling, the communication form can be arbitrarily changed. By enabling transmission to destination terminals according to availability and urgency, it is possible to improve the utilization efficiency of communication network equipment.

[Industrial application field]

The present invention relates to an improvement in a communication network device in which a network control device receives data from a plurality of terminals through polling and transmits this data to a receiving terminal during polling.

An example of a polling-type communication network device for communicating between terminals via a network control device is shown in FIG. 7, in which the network control device 10 polls terminals 1, 2, . 3. . . . It receives data sequentially from n and transmits this data to the receiving terminal, for example, 3 during polling.

Recently, the need for small-scale polling type communication network devices that perform communication between terminals via a network control device has increased.

In this case, at some times, for example, one terminal makes an inquiry to another terminal asking if there is data of a certain content, and this terminal responds to the inquiry. It is a notification system that notifies terminals of water levels exceeding the warning water level, fires, etc., and sometimes it is a scheduled transmission system that transmits data from one terminal to another terminal at a fixed time like a flood defense telemeter. It is desired to be able to improve the efficiency of the communication network equipment by being able to change the communication format, and by allowing the network control equipment to transmit according to the level of urgency when the inquiry response 1 is reported.

[Conventional technology]

Conventional polling-type communication network devices that communicate between terminals via network control devices are generally:
For example, in the case of a makeshift response system, this communication form is always maintained.

Note that the network control device transmits the data received by polling to the terminal when polling the receiving terminal.

[Problem that the invention seeks to solve]

However, if the system is small-scale, the time it takes to use it is short, and for example, sometimes it is a scheduled response type, and sometimes it is a notification type, and communication is carried out within the prescribed communication format (the above three types). If the format could be changed, usage efficiency would improve, but this is not possible because only fixed communication formats are available.

In addition, in the case of inquiry response type and notification type, the network controller transmits the data received by polling to the terminal when polling the receiving terminal, so even if there is a highly urgent There is a problem in that this cannot be sent with priority, resulting in poor utilization efficiency of communication network equipment.

[Means for solving problems]

The above problem is caused by multiple terminals 1.2.3., as shown in the principle block diagram of FIG. . . . A communication mode and auxiliary information setting unit 23 sets auxiliary information including one of a plurality of communication modes and its degree of urgency when transmitting data, and a communication mode is extracted and displayed from the received data at the time of reception. The network control device 10 is equipped with a communication mode extracting section 24, and a storage table storage section 14 that stores a table indicating the transmission source, the communication mode at the receiving end, the auxiliary information 9 and the communication contents including the degree of urgency, and a storage table storage section 14 that stores a table indicating the communication contents, and a plural Terminals 1, 2, 3. ...The sender received from,
From the data indicating auxiliary information 1 communication contents including the communication form and urgency of the receiving terminal 1, auxiliary information 1 communication contents including the degree of urgency are stored in the sender and receiving end unexplored columns of the storage table storage unit 14 for each communication form. This problem is solved by the communication network device of the present invention, which is equipped with a control unit 15 that reads the write/storage table storage unit 14 and controls the receiving terminal to transmit data with a communication format added thereto by polling according to the contents of the auxiliary information. Ru.

[Effect]

According to the present invention, when polling from the network control device 10,
Terminal 1.2,3. . . . The communication mode and auxiliary information sending section 23 selects one of a plurality of communication modes for the data to be transmitted to the network control device 10.

The network control device 10 receives this data, and the control unit 15 sends the auxiliary information including the
Write the auxiliary information 9 communication content including the degree of urgency for each communication type in the transmission source and reception end uncut columns of the storage table stored in the storage table storage unit 14, read the storage table, and communicate to the reception destination terminal. The format-added data is immediately polled and transmitted to the corresponding terminal according to the contents of the auxiliary information, for example, if there is an emergency, the receiving terminal receives it, and the communication format extraction unit 24 communicates based on the received data. Since the format is extracted and displayed so that it is possible to know which communication format data was sent, the communication format can be changed arbitrarily, and highly urgent items can be sent to the receiving terminal according to the urgency. Communication 7) Utilization efficiency of work equipment is improved.

When transmitting data to a terminal with a destination address by polling, the destination address and the source address in the column of the destination address in the storage table shown in FIG. 5 are stored in the destination address center section 44. The sender address is sent to the sender address center section 43, and the communication mode and communication content data in the corresponding column is sent to the communication mode center section 45. The data is set in the data center section 46, the entire data set is set in the communication data set section 47, and the data is transmitted to the terminal in the format previously explained with reference to FIG.

Is this a step in the program shown in Figure 6? 0°95.
100, 101, 102, 103, and 104.

In the communication network device of the present invention, a storage table as shown in FIG. 5 is provided so that the communication form can be changed arbitrarily, and when the communication form is arrangment or response 9 notification, the operation described below is performed. I'm trying to do it.

In the communication network device of the present invention, polling of the network control device 10 is normally performed in the order of terminal addresses 1, 2, 3, 4, etc. For example, the network control device 10 transmits data to each corresponding terminal, and during this polling, the network control device 10 causes each terminal to transmit data, and the network control device 10 receives the data.

However, among the messages sent from the terminal and received by the network control device 10, there is a message (“2”) that you want to urgently communicate to the other party.
If there is something that you want to communicate with the other party urgently (“1”), the network control device 10 will send the urgent message immediately, regardless of the polling order of the terminal. At the latest, for example, after polling three terminals, data is transmitted to this terminal (at this time, data is sent and received from the terminal).

This applies to steps 71 to 74.2 in Figure 6.
00,201, 75-78,202.203, 79-84,204,205, 85-90,
206,207.

Incidentally, during normal polling, if there is a message of 1" urgently directed to the polling terminal, it is of course transmitted at this time. Steps 96 to 101 in FIG. 6 correspond to this.

Next, the control computer 42 searches the storage table shown in FIG. 5 written in the storage table storage unit 14, and retrieves the auxiliary information for each communication form (part b in the program flowchart of FIG. 6). The case of transmitting data according to emergency "2", urgent "1", normal "0", and scheduled time at 3 o'clock will be explained according to the flowchart of the program shown in FIG.

In flowchart) 70, the polling address is set to (terminal address) 1.

In steps 71 and 71', a search is made to see if "2" is present in the auxiliary information section of all types of timing response sections in the storage table shown in FIG. 5. If not, the process proceeds to step 75;
In step 72, the receiving address, the sending address, the communication form 9 arrangement content, or the response content are extracted from the storage table in the order in which they are received, and the receiving address setting unit 4 in FIG.
4. Sender address center section 431 Communication mode setting section 4
5. Set it in the data set section 46, transmit it in step 73, clear the relevant column in step 74, and store the contents sent from the terminal in steps 200 and 201 as explained earlier. Write in each item.

Once all urgent matters have been sent, the next step is Ste Nobu 75.
．． At step 75', a search is made to see if "2" exists in the auxiliary information of all types of reporting sections in the storage table, and if not, step 79 is performed.
If there is a response, the same operation as explained in the case of the timing response is performed in steps 76, 77 and 78, 201 and 202.

Next, in steps 79 and 79', a search is made to see if "1" exists in the auxiliary information of all types of timing response units in the storage table.

If not, the process advances to step 85, and if there are, the following operations are performed in the order in which they occurred.

Each column of the storage table has a wait count counter created by software, and if you are in a hurry, you can
Add 1 to the waiting counter in the column where you found ``, and if there is ``1,'' then step 80
Each time the paddle is polled, 1 is added to the waiting counter for that paddle, and if the count value reaches 3 in step 81,
At step 82, the receiving address, the sending address, the communication type 2 arrangement content, or the response content are extracted from the column of the storage table containing "1", and the receiving address address center section 44 of FIG. 2 is extracted. Sender address center section 431 Communication type center section 45. Set it in the data set section 46, transmit it in step 83, clear the relevant column in step 84,
As previously explained in steps 204 and 205, the contents sent from the terminal are written into each storage table.

When the completion is completed, in step 85.85'', a search is made to see if there is "1" in the auxiliary information of all types of notification sections in the storage table, and the same operation as in the case of the above-mentioned delay response is performed in steps 86, 87.
Performed at 8B, 89, 90, 206° 207.

Next, in step 91, look at the scheduled time of the auxiliary information of all scheduled transmission sections in the storage table, and if there is one that has the specified time, select the receiving address, sending source address, and communication type 1 communication from this column. The content is extracted and set, sent in step 93, cleared in this column in step 94, and in steps 208 and 2O9, the content sent from the terminal is stored in each of the storage tables. Write in the column.

If it is not the specified time, then in step 95, in order to perform normal polling on terminal 1, the polling address is set to 1 of the receiving address, and the receiving address 1 of the storage table shown in FIG. 5 is set as the polling address. The source address, communication form, and auxiliary information are extracted from the columns and sent to the destination address center section 44 in FIG. Set in the source address center section 439, communication mode center section 45, and data set section 46, and step 9
In 6.98, “1” was added to the auxiliary information of the timing response section and reporting section.
” (even if the waiting counter is not 3), proceed to step 97.99,1 as in the normal case.
At step 00, the communication contents are set from the storage table in the data center section 46 of FIG.

Next, as explained earlier, in steps 210 and 211, the contents sent from the terminal are written into each column of the storage table.

Next, in step 103, the operation of adding 1 to the polling address and polling terminal 2 as the polling address is repeated until all terminals have been polled, and when all terminals have been polled in step 104, the process returns to step 70. Repeat the action.

In this way, the communication format can be changed arbitrarily, and highly urgent messages can be transmitted to the receiving terminal according to the urgency, so that the efficiency of using the communication network device can be improved.
