Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a data printing control system for processing and printing data from a plurality of transmitting stations in a telemeter system or the like.

In a telemeter system, data is transmitted wirelessly or wired from multiple transmitting stations to a center at predetermined intervals, and the center processes the received data, such as editing, and prints it out. It is something. Devices such as typewriters for printing output perform mechanical operations, so their operating speed is slow compared to the data transmission speed, so it is difficult to temporarily store received data in memory. Become. In this case, the data storage area of the memory is generally formed corresponding to the transmitting station, and the printing operation is performed after receiving and storing data from each transmitting station. Therefore, if the number of transmitting stations is large, the memory capacity must be increased proportionately.

An object of the present invention is to provide an economical configuration by reducing the capacity of a memory for temporarily storing received data. Examples will be described in detail below.

Figure 1 is a block diagram of an embodiment of the present invention, where the μCPU is a microprocessor, the ROM is a read-only memory that stores programs, printing specifications, etc., and the RAM is used to store received data and edit data. DEMC is a demodulation control circuit that demodulates received data, TPC is a print control circuit, TP is a typewriter, DB is a data bus, AB
is the address bus. Data is transmitted wirelessly or by wire from each transmitting station at predetermined intervals, the received data is applied to the demodulation control circuit DEMC and demodulated, and stored in the memory RAM under the control of the microprocessor μCPU.The edited data is The data is transferred to the print control circuit TPC and printed out by the typewriter TP.

For example, the memory RAM has areas allocated as shown in FIG. The start address of the data storage area is “0000”, “0008”, “0010”.
The number of data storage areas is smaller than the number of transmitting stations, and depends on the data reception time interval and the operating speed of a printing and recording device such as a typewriter TP. It is selected based on the following relationship and is configured to the minimum necessary number. The memory RAM also contains a reception step counter, a data storage area start address specification section, a data storage area status flag, a printing specification storage area, a printing step number storage area, an editing step counter, an editing data storage area for printing, and a typewriter operation flag. etc. are formed.

In conventional memory for storing received data,
As mentioned above, data storage areas are formed corresponding to the transmitting stations, but in the present invention, the data storage areas are formed in a smaller number than the number of transmitting stations,
Printout is not performed upon completion of data reception from all transmitting stations, but printout is controlled each time data is received from each transmitting station. For this purpose, a receiving step counter, a data storage area start address designation section, a data storage area status flag, an editing step counter, and a typewriter operation flag are newly formed.

The reception step counter is address ¥0018,
It is formed by ¥0019, and the relationship between the count contents and the start address of the data storage area is that the start addresses are ¥0000, ¥0008, and ¥0010, corresponding to the count contents ¥0000, ¥0001, and ¥0002. In addition, the data storage area start address designation section formed at addresses ¥001A and ¥001B of the memory RAM is set to one of the above-mentioned start addresses ¥0000, ¥0008, and ¥0010 in accordance with the count contents of the reception step. It is something.

Also, the data storage area status flag indicates the status of the start address ¥0000, ¥0008, ¥0010 of the data storage area corresponding to addresses ¥001C, ¥001D, and ¥001E, and the edit step counter indicates the status of the start address ¥0000, ¥0008, and ¥0010, corresponding to addresses ¥001C, ¥001D, and ¥001E. The relationship between the count contents and the start address of the data storage area is the same as that of the reception step counter. The typewriter operating flag at address ¥002F is used to display whether or not the typewriter is operating.

The printing specification storage area is at the address ¥001F,
Supports ¥0020 and ¥0021, starting address ¥0000,
The printing specifications corresponding to the transmitting station that sequentially accumulate received data from ¥0008, ¥0010 are read out and stored, for example, from the memory ROM, and the printing step number storage area is stored at the addresses ¥0022, ¥0023,
Supports ¥0024, starting address ¥0000, ¥0008,
The number of printing steps corresponding to the transmitting station that sequentially accumulated received data from ¥0010 is stored.

Figure 3 shows an example of a time chart, #1~
This is a case where data is received from transmitting station #3 and printed out, and FIGS. 4 to 8 are flowcharts. First, upon initial start, the system operates according to the flowchart shown in FIG. 4, and the steps of SUBRU 7 follow the flowchart shown in FIG. In addition
An RTS step indicates a return to the previous flow. Therefore, in FIG. 3, at the start, the reception step counter has a count of 0, and the start address designation section sets the start address to ¥0000. The process then proceeds to typewriter startup processing, in which the typewriter startup processing (power-on) includes motor startup, carriage, ribbon switching, and month, day, hour, and minute printing. At this time, the typewriter operating flag (address ¥002F) is turned on.

When data from the #1 transmitting station is received during the typewriter startup process, the received data is stored in the first data storage area at the start address ¥0000 specified by the start address designation section by the microprocessor μ.
Stored under CPU control. Data reception from the transmitting station operates according to the flow chart shown in FIG. In other words, the memory is
Read the start address from RAM addresses ¥001A and ¥001B, read the printing specifications from the specification table corresponding to the station number of the transmitting station, and calculate the number of printing steps. And the first address ¥0000, ¥0008,
Store the printing specifications at addresses ¥001F, ¥0020, ¥0021 in the printing specification storage area corresponding to ¥0010,
Address of printing step number storage area ¥0022,
Store the number of printing steps in ¥0023 and ¥0024.

After the above-mentioned processing is completed, it is checked whether the typewriter is in operation or not. If it is not in operation, the process moves to the flow of SUBRU23 in Fig. 8, and if it is in operation, the typewriter is in operation at the end of reception. Turn on the flag indicating that the
Shift to flow No. 23. In Fig. 3, the reception of data from the #1 transmitting station is completed during the operation of the typewriter startup process, the reception step counter is incremented to ¥0010, and the start address is ¥0008. The state flag address ¥001C is turned on because the first address ¥0000 is in use. This SUBRU
Upon completion of step 23, the process moves to step SUBRU7. Note that if the typewriter is not in operation, data printing processing is transferred after the step of SUBRU 23 is completed.

Upon completion of the SUBRU7 step, the typewriter enters the operating standby state. When the typewriter operation is completed, the flow shifts to PRSTR1 in FIG. 6.
That is, the status flag is checked and the data to be printed is retrieved. If received data for two stations or more is stored, the number of print steps is compared and the data with the smaller number of print steps is extracted. Also, an edit step counter is set, the edited data is stored in the print edit data storage area, and the status flag is turned off. That is, when the data stored in the data storage area is edited and stored in the edited data storage area for printing, the data storage area for storing received data becomes empty, and data from the next transmitting station can be stored. This shows that.

In Figure 3, the status flag of address ¥001C is turned off as the editing of the received data from the #1 transmitting station is completed, and the count content of the reception step counter is set to ¥0000, thereby making the first address ¥0000. is set to Data printing is performed according to the flow of PRSTR2 in FIG. In Figure 3, data is received from transmitting stations #2 and #3 while the received data from transmitting station #1 is being printed out, and the received data from transmitting station #2 is at the starting address ¥0000. It is stored in the first data storage area, and the count content of the reception step counter becomes ¥0001.
Since the start address is specified as ¥0008, the received data of the #3 transmitting station is stored in the second data storage area of the start address ¥0008, and while the received data of the #1 transmitting station is being printed out, the first and Since the received data is stored in the 2 data storage area, the status flags at addresses ¥001C and ¥001D are turned on, the reception step counter is set to ¥0002, the first address is specified as ¥0010, and the address ¥001F is set to ¥0010. #2 Printing specifications of transmitting station, #3 for address ¥0020
The printing specifications of the transmitting station are stored, and address ¥0022 contains the number of printing steps for #2 transmitting station, address ¥0023.
The number of printing steps of #3 transmitting station is stored in .

When the printout of the received data of the #1 transmitting station is completed, the status flag is checked, the editing step counter is set, and the number of print steps is compared for the #2 transmitting station and the #3 transmitting station. If the number of printing steps in the station is small, #2
The process moves on to printing the data received by the transmitting station, the contents of the reception step counter become ¥0000, and the start address is specified as ¥0000.

As explained above, the present invention provides memory RAM
A data storage area whose number is smaller than the number of transmitting stations and a start address designation part are formed in the data storage area, and each time data is received from a transmitting station, the data is stored in the data storage area at the start address specified by the start address designation part. , which controls the print output processing by a print recording device such as a typewriter and the data reception processing from each transmitting station in parallel, and when printing is performed by a print recording device whose operating speed is slower than the data transmission speed. The capacity of the memory RAM can be made small compared to the number of transmitting stations, and the telemeter system etc. can be constructed economically.
