Abstract

PURPOSE:To reduce the size of a subcontroller by setting an address for a terminal LSI successively from the CPU of the subcontroller and performing input/ output operation for the address to use a terminal LSI7 in corporated with a subcontroller. CONSTITUTION:The CPU10 of the subcontroller 9 outputs a set address and return data to one terminal LSI7 thorugh a bus 11 and parallel I/O12, and also inputs monitor data. The transmission line 2 of the system is connectd to the terminal LSI7 through an input/output part 6, and a main controller 1 accesses terminals 3 having addresses (i), (i+1)-(i+n) cyclically. The monitor data from the terminals are inputted from the terminal LSI7 to the CPU10 through the I/O12 and bus 11. Then, the subcontroller 9 uses only one terminal LSI7 to reduce the size of the subcontroller 9 of the remote monitor controller.

[Detailed Description of the Invention] [Technical Field] The present invention is directed to a remote monitoring and control device that connects one main controller, a large number of terminal devices, and all transmission lines, and uses a time division multiplex transmission system. In addition to the main controller that monitors and controls the entire system, a remote monitoring and control device equipped with a Suzuko Citroler is used to monitor and control the system from outside the system, for example by using a telephone line17. It is related to.

[Background technology]

Figure 1 shows an example of a remote monitoring and control device using a general time-division multiplex transmission system, in which a transmission line (2) extending from one main controller (f1) has many terminals. This device (3)... All connections are made, and time-division multi-vehicle transmission (1) is sent from the main controller to each terminal device (3)...

When the double-view input from T-JS (5) returns the original ticket (3), the main controller (1) that received this return signal uses the contents of this return signal as a reference. Detects the operation of the main controller (1) in advance to make it subordinate to this wall switch (1).

When the terminal device (3) currently set to address i is accessed at the timing shown in Figure 5 (A), it outputs a relay drive signal at the timing shown in Figure 5 (B), and at the same time All of the control data communicated at that time is switched with three ties (see Figure 0\) and output from the control output terminal. This will result in subcocitrolola (9)
2, when controlling the 11A system, set the address of the Ffr thorn in the partial LSI +7) and distribute the return data to the monitoring input terminal.
It is sufficient to output the signal until the +121 signal rises, and when performing continuous monitoring, when the above relay live signal rises, the signal generated at the control output terminal of the partial LSI (7) It is sufficient to input the parallel output klAi visual data to the parallel I/Of+21.

The sub-controller (9) of the embodiment in FIG. 4 is manufactured as described above, but as shown in FIG. To wake up every time, if you set the switch i with the 1° tie in Figure 5 and output it to the CPU (101), it will be sent to the device corresponding to this address iK. However, even if the address is set in the tie 3-J of t! in the same figure, the parallel l10 (C via 14K gold) is
Since the relay live signal for the address set from P U flu) rises, a problem arises in that control and monitoring at address i cannot be performed. . Therefore, in order to perform all of the processing operations as described above, an invalid address that the main controller T1+ will not access is provided in advance during system design, and this #aL, All valid addresses are copied (by setting 7+ at normal times, while this invalid address is set, the above temporary tree L is copied)

The configuration may be such that when the relay drive signal is detected to have risen, the invalid address is output from the CPU (10+) again. Figure 6 shows the CPU that performs the above production. U1+o) is shown in the flowchart of Fig. 6. In the flowchart of Fig. 6, when performing control, return data is output at the same time as when performing control, and when performing monitoring, the above mentioned "reading of monitoring data" is used when performing monitoring. It is produced only by

In the case of the flowchart in FIG. 7 as well, the first return data of the control is output at the time of ``setting the atmos'', and the ``reading of monitoring data'' is the operation when performing monitoring (Example 2). Figure 8 to Figure 10 show main part diagrams, time charts, and flowcharts of the second embodiment of the present invention.In the case of the first embodiment described above, all invalid addresses are set. This was provided in order to improve the problem that the CPU (+01) software burden in the sub-cositroller (9), such as a sub-cosplay controller (9), is too low.In other words, the Suzuco-sitroller with the same configuration as the embodiment in FIG. At (9) 2, there is a latch (13) that latches the address output of the terminal LSI (parallel l/Ot12 due to the falling edge of the relay drive signal of 71), and a latch (13) that latches the address output of the terminal LSI (parallel l/Ot12), and this output of Sochi (13).

Therefore, by setting the output time of the one-shot F/F (16) to an appropriate time such as 1 hour in Fig. 5, it is possible to set the output time of the one-shot F/F (16) to an appropriate time such as 1 hour in Fig. 5. )→, or the relay live signal corresponding to the previously set address as shown in Figure 9 (:), which appears at the 1 mark after changing the address at the timing of t in Figure 435, is gated. is applied and the input to the parallel l10f121 is cut off, and only the relay drive No. 1 shown in FIG. 9 (e) corresponding to the setting address i in FIG. It will be transmitted to

In this case, the O-chart of the CPU (software 101) is as shown in FIG. 10, and the software burden is 75λ, which is a decrease in I.
