Abstract

PURPOSE:To simplify the constitution and to improve the operability of a system controller circuit, by performing ON/OFF of the system power supply as well as stopping operation of the system with just a single switch. CONSTITUTION:Just a single switch S turns on and off the power supply of a system and also stops the system operation. A switch input (b) obtained when the power supply is off is used to an instruction to turn on the power supply and to stop the initial value of the system operation. At the same time, the input (b) obtained when a system controller controls operations other than that of a stop state is used for an instruction to stop the system operation. Furthermore the input (b) obtained in a stop state of system is used for an instruction to turn off the power supply. In such a way, just a single switch S can perform both ON/OFF operation of the system power supply and stop operation of the system.

Description

[Detailed Description of the Invention] The present invention relates to a method of operating a system controller that electrically controls various devices, and simplifies the system controller by using the same switch for turning on/off and stopping the system. The purpose is to improve operability when turning the power on and off.

When controlling electrical/Kameko equipment, especially when a single device is required to perform multiple operations (for example, recording, playback, fast forwarding, rewinding, etc. of a video recorder), the assembling machine@niya has a system controller in the circuit section. It is common to have a switch that specifies all modes of operation. I-F,
A conventional example of a system controller will be explained based on the drawings.

FIG. 1 is a block diagram of a configuration example of a conventional system, and FIG. 2 is a flowchart explaining the operation of the system of FIG. 1. (1) in Figure 41 is the system controller operation fL section consisting of multiple switches, where a is the output from the power on/off switch, b is the output from the stop switch that commands the system to stop, and C is the other operating modes. This is the output from the specified switch. Conventionally, a power supply on/off switch and a power supply switch are provided separately. 1st
The system controller control unit (2) in the figure is a controlled device (
5) is performed in accordance with the output from the system controller operation section (1), d is a control signal to the controlled device (5), and e is a signal from the controlled device that informs the state of the device. g is the output of the main power on/off command,
As a result, the power line f and the power line h of the controlled device (5) are turned on/off.a ('') is a main power switch operated by an electric signal g, and (4) is a power source.

Conventional system controllers do not allow the power line f to continue even when the main power switch (3) of the system is off.
), and is in a state of waiting for the input of the input switch output 8 of the system controller operation section [1]. For convenience of explanation, here, we will define the system stop state as the state in which the main power switch (3) is on during normal system operation, but the system is waiting for input without any input, and operations other than the system stop state will be defined as the system stop state. While running,
Alternatively, the transition from one action to another is defined as the system action state. In the conventional system shown in Fig. 1, the main system shown in Fig. 1 is predicted to occur when the power is cut off due to a power outage or disconnection while the system is operating (for example, while loading tape in a video recorder). ! Immediately after turning on the switch (3), initial control is required to bring the system to a stop state. In FIG. 2, the portion L is the portion that controls the initial L.

In addition, N in Figure 2 is the system controller m in Figure 1.
Operation N (1) The equipment is controlled according to the outputs a, b, and c from the switches, but during system operation, the output a from the power on/off switch is output from the system controller control unit (Fig. 1). 2), the system is temporarily stopped and then the main power switch (3) is turned off, that is, P in the flow chart in Figure 2.
operation is required.

An object of the present invention is to reduce the number of switches on the operating section by making the system controller operating section serve as a power on/off switch and a stop switch, and to increase the control of the conventional system controller to +J Wfr. The aim is to improve the ease of reading and operability.

That is, the method of the present invention is a method of operating a system controller that is equipped with a switch for inputting various control port α commands and controls the system by inputting the switch, and includes a switch for turning on and off the power of the system. The switches that stop the system are the same, and the switch input when the power is off is a command to turn on the power and stop the initial value of the system operation, and the system controller is not in the stop state. A switch input when controlling the operation of the system is used as a stop command for the system, and a switch input when the system is in a stopped state is used as a power-on command. The desired purpose was achieved by turning the M on/off and stopping the system with a single switch.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. 8th
The figure is a circuit and overall system block diagram of the dual-purpose switch input section which is an embodiment of the present invention, Figure 4 is a flowchart showing the operation of the system shown in Figure @8, and Figures 5 (a) (b)
3 is a time chart showing the waveforms of each part in FIG. 3 and a diagram illustrating the state of the system.

As an example of the implementation of the present invention, (0) in FIG. 8 is a switch circuit (hereinafter referred to as an additional circuit) that is added to the conventional system in FIG. 1 (=I), and the other blocks are the conventional system in FIG. Because of the additional circuit (6), the independent WI7JJ on/off switch in the system controller m part (1) in Figure 1 is omitted, and the % of the conventional example in Figure 1 is omitted. There is no output a from the fil ono-off switch.

In the additional circuit section (6) in FIG. 8, G1 is an inverter with hysteresis characteristics, G2 is a NANII gate, and F
F is a flip-flop, dirt is a pull-up resistor, Toshi, C1
is the dual-purpose switch S of the system controller operation section (1)
An integrator for removing chattering, R3 and R4 are pull-town resistors, and C2 is an FF when the power supply (4) is operating.
This is an initial reset circuit to set the output Q to IIL.
"H"' when the system is in stop state rI3, and "H" when the main power switch (3) is turned on.
' is output. The operation of the additional circuit section (6) will be explained below based on the drawings.

In Figure 8, the system controller control unit (2)
F3 m or the wave train 1 device (5) is provided with a terminal that outputs an "H" signal when the system 1 is stopped, and the signal is designated as j. Furthermore, a terminal is provided to output the 1111 ++ signal when the main power switch (3) is on.
Let that signal be i, F) NANI of tJ signals i and j)
is taken and supplied to the data input 1) of the flip knob FF. If the main power switch (3) is off, the signal l
Since “l” is at the IT level, the flip-flop F
The data input of F becomes the H" level. When the dual-purpose switch S of the system controller operation section (1) is pressed, the output of the flip knob FF (2 changes from the 11L" level to the "H" level. 11 ++ level, and the main tam switch (3) is turned on by the output Q. At the same time, the system controller control unit (the output of the stop switch is being input). If the output of the stop switch has a higher priority than the output C from 1 to Kl'L, the controlled device (5) will always be in the stop state even if it is pressed twice. Main power switch (when turning off the 3rd turn off, turn off the 17th resonator 1'F data manual)
It is necessary for the main power switch (3) to be at the "L" level, but in this case, the signal 1 indicating that the main power switch (3) is on is "H" = level, and the signal J indicating the stop state is
Must also be +1 il IT level. In other words, even if you press the dual-purpose switch 8 when the system is in the stop state (1), the stop command will only be output, but the main power switch (3) will not be turned off. The main power is turned off only when 8 is pressed. Normally, when turning off the main power, the system is brought to a stop state, so it is possible to perform the two operations of stopping the system and turning off the power with one switch, and the outstanding performance is improved.

This will be explained in more detail with reference to the waveforms of each part in FIG.

Transition of the system to the stop state depends on the "L" level of the output of the stop command of the dual-purpose switch. When the main power switch (3) is on, if the "L" level of the output is detected, the system enters the stop state. Move to. Furthermore, the on/off operation of the main power switch (3) depends on the data input of the flip-flop FF shown in FIG. , ++. Therefore, the data power of FF 1) is at the “■” level, and the clock power of l″F ([
At the rising edge of (L), the output Q of F becomes "H", so the main power switch (3) is turned on. When the main power is turned off, signals L and 4M are turned off only after the dual-purpose switch S shown in Fig. 8 is pressed and the system enters the stop state.
Both signals become "■", and a signal of "L I+ level" is supplied to the FF data input 1).If the dual-purpose switch S is pressed again here, the FF clock input is OK. At t, the FF output Q becomes L",
The main wl source switch (3) is turned off.

Comparing the flowchart shown in FIG. 2 with the conventional example shown in FIG. 2, it is found that the initial control of the system shown in FIG. 2 is unnecessary. Furthermore, the processing of U and V in Fig. 4 can be performed by the additional circuit section (6 units) in Fig. 3, and the part P in the flow chart of the conventional system shown in Fig. 2 is also inconvenient, which simplifies the system controller. effective.

In the above description, the case where the additional circuit (6) is added is described as an embodiment of the present invention, but if a microprocessor is used in the system controller control section (2), the internal microprogram can be written more easily. Adding an additional circuit (6) lx <Similar effect can be obtained;
f Child device Q operation t1. It is effective for improving the performance and simplifying the system.

As described above, according to the present invention, the system can be turned on/off and the system can be stopped with a single switch, so the number of switches in the operation section can be reduced, and the dual-purpose switch can be operated. The operability is the same because only one button is required. Moreover, it is possible to omit some of the operations listed in 4b in the flowchart of the conventional system.
This has the effect of simplifying the controller control section compared to the conventional one.
