Abstract

PURPOSE:To accelerate the response of light dimmer control operation without delaying the response of the monitor operation by retrieving a terminal device with an interruption polling and sending back the call monitor data individually to perform the light dimmer control operation. CONSTITUTION:When receiving an interruption request signal by a transmission/ reception means 16, a main control board 1 actuates an interruption polling means 17 immediately to retrieve the terminal device 2 which is transmitting the interruption request signal. When the device 2 is specified, an individual polling means 13 calls the device 2 individually and transmits a transmission signal VS of monitor mode to send back a monitor data signal. The called device 2 sends back a monitor data signal. With this polling operation, the monitor data showing the states of up and down light dimmer control switches SWa and SWb are sent back to the board 1. Then the board 1 decides from the monitor data whether or not the monitor input signals S1 and S2 are changed to 0 from 1 respectively and then decides the start or stop of the light dimmer control operation.

The operation of the embodiment will be specifically explained below. Figure 6 is a flowchart showing the control operation of the main operation panel +1), and Figure 7 is a flowchart showing the operation of the control monitoring terminal (2). If not, the main operation panel (1) operates in a normal mode in which it cyclically calls the terminals f21 (2a) (2b) connected to the signal line (3) to send and receive control data or monitoring data. There is. However, terminal devices (21 (2a) (2b) that are set to interrupt operation mode)

Monitoring terminal (2b) that monitors Wa ) (SWb )
is normally not borisiged by Sade. Next, when the up dimmer switch (FFSVa) or the up dimmer switch (SWb) connected to one of the monitoring terminals (2b) is turned on or off, the monitoring terminal (2b) is turned off. Second monitoring input means (6
"1" is set in any of the pits corresponding to the monitoring input signals (st) (S2) in b), and an interrupt flag is set in the interrupt flag setting means (7). Next, when the interrupt flag is set, the interrupt signal generating means (8) raises its H level in synchronization with the start signal (ST) of the transmission No. 4m (Vs) transmitted to the signal line (3).

This search operation divides the large number of terminals (2) (2b) into an appropriate number of groups, calls the terminals i2)+:2b) for each group, and searches whether the interrupt flag is set or not. It looks like this. In the [implementation], the t-code signal MD) is set as the divided holisic t-code (1, 0, 0, US), and the terminal device (21 (2
b,), only the upper 4 pits of the address of address signal (
The interrupt data transmission signal (VS) to be transmitted as AD) is sent from the main operation panel fl to 16 terminal devices with the same upper 4 address bits + 2) (2b ”)
The crews are sequentially called, and the lower 4 pits of the address of the terminal +21 (2b) are returned from the terminal +2+ (2b) where the interrupt flag in each terminal is set and the standby pulse signal (M )), the main control panel (
1), and on the main operation panel fi+, the lower 4 addresses of the returned address are sent using the return signal (VS).
The terminal device +21 (2b) which is issuing the interrupt request signal (IRQ) is specified by combining the address and the upper four pits of the address transmitted by the transmission signal (Vs). By the way, the top 4 addresses are the same (same/

The data sent back when an interrupt is requested at the same time is made up of multiple terminals (21 (2b)) with the lower 4 addresses of their addresses superimposed to form data, and the main operation panel (11) receives an interrupt request signal (I
It becomes impossible to identify the terminal device 12] (2b) that is emitting RQ). Therefore, if multiple terminals of the same group (
If an interrupt request signal (IRQ) is issued simultaneously from 21 (2b), then each terminal (2) (2b) of that crew
is sequentially called individually to search whether the interrupt flag is set or not, and to identify a plurality of terminal devices (21 (2b)) that are issuing an interrupt request signal (IRQ). , in the embodiment, terminal device +2) (2b)

They were returned as (R7) and (Ro), respectively.
If "1" and "o" of the female pit data are transmitted in a superimposed manner, one of the pit data of the address that should normally be returned as a 2-bit signal becomes a 1-pit signal. By making it a long pulse signal, it is now possible to easily detect that the lower four hits (different from each other) of the addresses of multiple terminals in the same group +2+(2b) are being transmitted in a superimposed manner. ing. In other words, if any of the Attice pit data returned by the interrupt Borisig operation is a long pulse signal obtained when "1" and "o" overlap, multiple terminal devices +2) (2b) can be determined to be issuing an interrupt request signal (IRQ). In the figure (R8), the status pit (RP) is parity-hi-so-to.

When the terminal device f2) (2b) that is emitting the interrupt request signal (IRQ) is identified as described above, the individual ballistic means (1) individually calls the terminal device 112) (2b) to perform monitoring input. Transmission of a monitoring shade (set the seventh-dead signal (MD) to (,0,0,1,US)) to return the monitoring data signal (SD) (Sn2) created by means (6a) and (6b) Sends a signal (VEI). The called terminals (2) (2b) return 4-pit supervisory data signals (SD) in synchronization with the return standby pulse signal (WP) of the transmission signal (Vs). In this case, each of the 1st to 4th pits (R3) to the monitoring data signals (SD) (SD')
(RO), (R7) to (R4) correspond to the monitoring input signals (Sl) to (S4), respectively, and the monitoring input signals (
Which of S1) to S1 has changed and what level has changed can be quickly and reliably grasped on the main operation panel (1). In addition, the main operation panel (l) checks whether the monitoring data signal (SDXSD,) is transmitted correctly based on the heritage hit (pR,), and if it is not transmitted correctly, the terminal (2) is checked again. ) (2b) individually to call the monitoring data signal (S

v8) is sent, the interrupt fluff of the interrupt fluff setting means (7) of the terminal device (2b) is reset, and the data of the monitoring input means (6b) is also reset.
Next, the process waits until the monitoring input signals (Sl) to (S4) change.

Next, when monitoring data indicating the status of the up dimmer switch (SWa) and the up dimmer switch (A) is sent back to the main operation panel f1) by using the above-mentioned interrupt/interrupt voltmeter operation, the main operation panel In (1), based on this monitoring data, it is determined whether the monitoring input signal (SI) (, 82) has changed from "1" to "0", and whether the dimming operation is started or not. A complete decision will be made as to whether to stop the production of Koei. That is,
Up or I''i dimmer switch (SI

After sending out the lighting load +l (signal), a smooth dimming signal is sent to gradually dim the lighting load +l [ll] at a constant speed in the direction of turning off the lights, and the monitoring input signal (Sl) changes and the light is output to the scaffolding. is the control terminal (2a) K highest level signal (

Do), and when this coat data (DC) is "1", frames as shown in the table below are sent using frame data consisting of the second to fourth pits. However, in this case, data after the fifth pit becomes meaningless.

On the other hand, when the code data (DC is "0", the 2nd to 8th
The dimming level can be set in 256 gradations using 7-pit level data. The control terminal (2a) uses a transmission signal (vs) K to determine whether the dimming control data sent from the main operation panel (1) is set data or level data, and adjusts the control operation to a predetermined operation based on the set data. When the alarm j dimmer switch (Sa) is turned on at time t0, the monitoring terminal (2
An interrupt request signal (IRQ) is immediately issued from L),

Therefore, the access cycles (intervals) of other monitoring terminals, control terminals, and control/monitoring terminals hardly change, and the response speed of other control/monitoring operations is not slowed down. ,Moreover,
The lighting load is controlled by calling the dimmer switch's monitoring terminal with priority using an interrupt signal and sending back the monitoring data.
Since the dimming operation is performed, the response of the dimming operation is quick, and the effect is that the operator of the dimmer switch does not feel strange.
