Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power supply control system, and particularly to a power supply control method that has a plurality of terminal devices, such as a banking device, and in which one of the terminal devices is a master device and the others are slave devices. It relates to a power supply control method for each terminal device in a system.

Conventionally, cash dispensers and the like have been widely used as banking devices.

Each of these cash dispensers and the like functions as a terminal device under the control of the center.

Conventionally, each of these terminal devices included a control device, but one of the multiple terminal devices is used as a parent device, and the remaining terminal devices are subordinated to the parent device as slave devices. This eliminates the need for a control device for each terminal device, making it possible to configure the system at a lower cost.

In this case, if the power on/off of each terminal device was controlled individually as in the past, it would be necessary to control the power on/off for each terminal device while always taking into consideration the relationship between the parent device and the child device. The power supply control becomes complicated because it is necessary to operate the attached switches.

Therefore, the present invention provides a power supply control method that allows one control unit to control the power supplies of a plurality of input/output crab units.

Another object of the present invention is to provide a power supply control system that allows one control unit to control the power supplies of a plurality of input/output crab units without providing a special signal line for power supply control.

Still another object of the present invention is a power supply control system in which a master unit and a slave unit are configured as a unit, and an input/output unit can be shared by both units.

In summary, this invention sends a signal from the remote monitor to the base unit according to the operation of each switch corresponding to the base unit and slave unit, and the base unit responds by supplying power to the control unit, and each The input/output crab unit controls the corresponding power supply by the corresponding control signal from the control unit.

Furthermore, the power supply of the master unit is controlled by either a signal from the remote monitor or a control signal, and the power supply of the slave unit is controlled by the control signal.

This control unit 10 is provided only in the base unit 100 and includes a center interface section 11, a control section 12, and a remote monitor interface section 13.

The center interface section 11 includes a transmission control circuit 111.
This circuit 111 is connected to the modem 3.

Furthermore, data received by the transmission control circuit 111 is given to a decoder 112.

Based on the sent data, the decoder 112 decodes from the center 1 whether there is data to control each device unit 20, 20' (ie, the corresponding power supply unit) 40, 4σ, and whether it is on or off.

If the command from the center 1 is to turn on the power supply unit 40 of the base unit 100, the decoder 112 sets the corresponding flip-flop 113.

Further, if the data from the center 1 is a command to turn on the power supply unit 40' of the slave unit 200, the corresponding flip-flop 114 is set.

Further, if the data from the center 1 is a command to turn off the power of the base unit 100, the decoder 112 resets the flip-flop 113, and if the data is a command to turn on the power supply unit 40' of the slave unit, the decoder 112 resets the flip-flop 113. For example, the corresponding flip-flop 114 is reset.

Therefore, from the Noritsu flop 113, the base unit 100
Command signal CPO1 for turning on the power supply unit 40 of
is obtained, and a command signal CPO2 to turn on the power supply unit 4σ of the slave device 200 is obtained from the flip-flop 114.

That is, when the terminal device 30 of the base unit 100 is in operation, the corresponding flip-flop 122 is set, and when one operation is completed, the corresponding flip-flop 122 is set.
Reset.

Furthermore, when the terminal device 30' of the handset 200 is in operation, the corresponding flip-flop 124 is set, and when the operation is finished, the control flop 124 is reset.

Therefore, flip-flops 122 and 124 provide signals indicating that the corresponding terminal device 30 or 30' is in operation.

The signal from flip-flop 124 is provided on line US2 of channel CH2.

Additionally, the outputs of flip-flops 122 and 124 are
Both are gated by OR gate 123 and provided to line US1 of channel CH1.

The remote monitor interface unit 13 includes a transmission control circuit 131, and has respective channels CHO, CHl,
It sends data to each line of CH2 and receives data from each line.

Furthermore, with reference to FIGS. 3 and 4, the device units of the parent device and the slave device, which are each intercepted by the same unit, will be explained in more detail.

Below, the device unit 20 of the base device 100 will be mainly explained, and only the different parts of the device unit 20' of the slave device 200 will be explained.

In this embodiment, the following may be considered as a mode for controlling the power supply.

First, there is a manual mode in which the power of both the base unit and the slave unit is manually turned on and off.

Another aspect is an automatic mode.

For this purpose, a mode changeover switch 211 is provided to change over between manual mode and automatic mode.

A switch 212 is also provided for turning the power on and off in manual mode.

Furthermore, several control modes are also possible in automatic mode.

That is, one of them is to control by a timer, such as a likelitimer, one of which is to control according to the command from the center 1, and the other one is to control according to the output of the line RD or SD. It's about controlling.

For this purpose, a manual switch 213 is provided for switching these automatic control modes.

A contact 211a of the mode changeover switch 211 sets the automatic mode, and a contact 211b sets the manual mode.

A contact 212a of the power switch 212 sets the power on, and a contact 212b sets the power off.

Further, the contact 213a of the switch 213 is set to be controlled by a command from the center 1, the contact 213b is set to be controlled by the output of the line RD or SD, and the contact 213c is set to be controlled by, for example, a likelitimer. Set.

The output of switch 211 is provided as one input of AND gate 214, and is inverted by inverter 215a and provided as one input of AND gate 215.

Also, the output of the switch 212 is this AND gate 215
is given as the other input.

Therefore, the output of AND gate 215 is applied to one input of OR gate 219 as a command signal to turn on the corresponding power supply unit.

Line RDO of channel CHO is connected to O via the receiver.
It is given as one input of R gate 216.

At this time, this one input is grounded through the resistor 216a.

The other input of OR gate 216 is connected to line SDI of channel CH1 via a receiver.

The output of OR gate 216 is provided to monitoring circuit 210.

The monitoring circuit 210 includes a power-on command detection circuit 210a receiving the output of the OR gate 216 and an AND game) 210
b and retriggerable monostable multivibrator 210C
It consists of

The power-on command detection circuit 210a detects whether or not the output data of the OR gate 216 includes a power-on command, and after detecting the power-on command, always maintains its output at a high level.

The AND gate 210b is connected to this power-on command detection circuit 21.
It receives the output of 0a and the high-level trigger pulse output following the closing command of OR gate 216, and provides the output as a trigger input to retriggerable monostable multivibrator 210c.

This monostable multivibrator 210c is configured to maintain its output if it is retriggered within 5 seconds, for example, and the output is transmitted to the contact 2 of the switch 213.
13b.

The output of the like-reliable timer 217, which provides one aspect for automatic control, is provided as one input to an OR gate 218.

The other input of this OR gate 218 has a channel CH1
A line US1 is applied through the receiver, and its output is connected to the contact 213c of the switch 213.

A contact point 213a of this switch 213 is connected via a receiver to a line for issuing a swing command from the center 1 through the center interface section 11 of the control unit 10.

The output of the switch 213 is given as the other input of the AND gate 214, and the output of this AND gate 214 is given to the other input of the OR gate 219 as a power-on command to turn on the corresponding power supply unit.

Therefore, a signal PON1 for turning on the power supply unit 40 of the base unit 100 is derived from the OR gate 219.

Note that the device unit provided in slave device 200 differs from that provided in parent device 100 described above in the following points.

That is, the handset 200 is not directly controlled by the remote monitor 300, and therefore is not connected to the line RDO of the channel CHO of the remote monitor 300.

Therefore, the human power of OR game) 216' is resistance 2
16a', it is always held at a low level.

The output of the OR game 219' of the device unit provided in the handset 200 shown in FIG. 4 becomes a signal PON2 for turning on the power supply unit 40' of the handset 200.

In the above configuration, operations of these embodiments will be explained below.

First, a case in which power is manually controlled for each of the base unit 100 and the slave unit 200 will be described.

Here, the case of the main unit 100 will be explained as a representative,
A description of the handset 200, which operates in a similar manner, will be omitted.

When manually controlling the power of the base unit 100, first, connect the automatic mode or manual mode changeover switch 211 provided in the power control section 21 of the device unit 20 to the contact 211.
Switch to b.

In response, a low level voltage is derived from this switch 211, which is made high level by inverter 215a, and AND gate 215 is opened.

At the same time, the low level voltage from this switch 211 closes the AND gate 214 and invalidates the output of the switch 213.

Subsequently, when it is desired to turn on the power switch, the power switch 212 is switched to the contact 212a side.

Then, a high level output is obtained from this switch 212, the output of the AND gate 215 also becomes high level, and the high level signal P is output from the OR gate 219.
ON1 is obtained.

Moreover, when turning off the power, this switch 212 is switched to the contact 212b side.

In this case, a high level cannot be obtained from the AND gate 215, and the output PON1 of the OR gate 219 also becomes a low level.

By the output PON1 of this OR gate 219, the base unit 1
The AC power supply section 42 of the power supply unit 40 of No. 00 is turned on or off.

Next, a case in which the power supply is controlled in automatic mode will be described.

In this automatic mode as well, as described above, there are three possible control modes, and first, the case of on/off control based on the control signal from the center 1 will be explained.

At this time, switch 211 is set to automatic mode, that is, contact 2
Switch to 11a side.

Then, AND gate 215 is closed and the output of manual power switch 212 is disabled.

At the same time, AND gate 214 is opened and the output of switch 213 is enabled.

At this time, this switch 213 is switched to contact 213a for power control based on a message from the center.

On the other hand, the center 1 sends a control signal to that effect to the control unit 10 of the base unit 100.

Then, as previously explained with reference to FIG. 2, a high level signal cpoi is obtained from the corresponding flip-flop 113 included in the center interface section 11 of the control unit 10.

This signal cpoi is given to the power supply control section 21 of this device unit 20 as shown in FIG.

Therefore, a high level output is obtained from the AND gate 214, and a high level PON1 is obtained from the OR gate 219.
is obtained.

This signal PON1 turns on the AC power supply section 42 of the power supply unit 40 of this base unit 100.

A further response in automatic mode is controlled by a likelitimer 217.

At this time, the mode selector switch 211 is switched to the automatic mode, and the switch 213 is switched to the contact 213c for control by the timer 217.

It is assumed that the timer 217 continuously derives a high level signal during the period when the power is to be turned on, and derives a low level signal during the period when the power is turned off.

Therefore, if a timer-on signal is obtained from this likeli timer 217, the switch 2
A high level is applied to the AND gate 214 through the gate 13.

Therefore, a high level signal is obtained from this AND gate 214, one input of which is set at high level by switch 211.

Accordingly, the output PONI of the OR gate 219 becomes . . . level, turning on the power supply unit of the base unit 100.

The OR gate 218 is further connected to the line U of the channel CH.
SI is connected through the receiver as appropriate.

This is because even if the output of the like-reliable timer 217 goes low, that is, even if the timer 217 turns off, the power cannot be turned off as long as the base unit 100 or slave unit 200 is in operation. , for which this line US1 is connected to an OR gate 218.

As explained earlier (FIG. 2), this RAID/US1 is sent from the OR gate 123 of the control section 12 of the control unit 100 through the remote monitor interface section 13.

Therefore, if either the parent device or the child device is in operation, the power supply unit 40 of the parent device 100 cannot be turned off.

For example, when the like timer 217 of the base unit 100 is turned off, if the input/output crab unit of the slave unit 200 is still operating, a high level is obtained from the flip-flop 124 of the control unit 12 shown in FIG. It will be done.

Therefore, the line US1 of the channel CH1 also becomes a zero level, and the input of the OR gate 218 shown in FIG.
・Becomes level.

Therefore, the output pON1 of OR gate 219 also maintains a high level.

Therefore, for example, even if the timer of the base unit 100 operates, if the slave unit is in operation, the power of the base unit remains on because it is necessary to keep the control unit 10 operating.

Then, this timer 217 is turned off and the line U
When S1 becomes low level, that is, when either the main unit or the slave unit finishes operating, the output of OR gate 218, that is, the output PON1 of OR gate 219 becomes low level, and the power supply unit 40 of this main unit 100 is disconnected. becomes.

Another control aspect in automatic mode is control according to the state of each line of channels CHO, CH1, and CH2.

In this case, the mode changeover switch 211 is
The switch 213 is switched to the automatic mode contact 211a, and the switch 213 is switched to the contact 213b.

Then, the power switch 303 for the base unit of the remote monitor 300 is turned on.

Then, this remote monitor 300 is connected to the line RDO.
Since the switch 303 is on from
A command to turn on the power supply unit 40 of the base unit 100 is sent to the DO.

This power-on command from line RDO is given to power-on command detection circuit 210a included in monitoring circuit 210 via OR gate 216 in FIG.

The power-on command detection circuit 210a detects that the input receive data includes a power-on command, and thereafter continues to output a high-level signal.

Further, this receive data includes high-level data.

Therefore, the high level from this line RDO is OR
It is applied via gate 216 to AND gate 210b.

AND game) 210b, the power-on command detection circuit 21
A high-level signal from 0a and a high-level signal from line RDO lead to a high-level output, which is provided as a trigger for the retriggerable monostable multivibrator 210c.

Therefore, this monostable multivibrator 210c is triggered, and a signal at the no-y level is obtained from this circuit 210c.

Accordingly, the signal is applied to the OR gate 219 via the switch 213 and the AND gate 214, and the output PONI of the OR gate 219 becomes high level.

Therefore, the AC power supply section 42 of the power supply unit 40 of the base unit 100 receiving this signal PON1 is turned on.

When the power supply unit 40 is turned on, the control unit 10 performs polling on the lines SD of each channel CHO, CHI, and CH2.

In other words, the control unit 10, in response to the power supply unit 40 being turned on and power being supplied,
Control signals are sequentially sent to the turnout units corresponding to the switches of the remote monitor 300 (in this case, the master switch 303).

Therefore, the high level of line SDI is applied to AND gate 210b via OR gate 216.

Accordingly, a signal at the NO level is again derived from this AND gate 210b, and the monostable multivibrator 210
Retrigger c.

Therefore, the output from this monostable multivibrator 210c will maintain a high level.

The retrigger time interval of this monostable multivibrator 210c is set to a constant time, such as 5 seconds, for example.

Then, if there is no polling from the control unit 10, that is, a high level signal from the line SDI for 5 seconds or more, the output of the retriggerable monostable multivibrator 210c becomes low level.

Therefore, the output PONI from the OR game 219 is at a low level, and the power supply unit 40 of the base unit 100 is turned off.

More roughly speaking, the input/output crab unit (in this case, the input/output crab unit of the main unit) performs predetermined operations based on control signals sent sequentially, and also performs predetermined time intervals (
If the control signal is not received for more than 5 seconds in this case, the power supply from the corresponding power supply unit is cut off.

Note that for the device unit of the child device shown in FIG.
The difference is that it is not connected to the DO.

Therefore, the device unit 20' of this slave unit 200
That is, the power control unit 21' is turned on by a power-on command on the line SD2, and thereafter is controlled solely depending on the polling data from the control unit NO of the base unit 100, that is, the data on the line SD2.

The polling data from the control unit 10 of the base device 100, that is, the polling data on the lines SDI and Sn2, is given to each terminal control section 22.22', and the terminal control section 22.22' controls the terminal device 30 based on the data. The terminals 31 to 3n, 31' to 3n' are controlled.

FIG. 5 is a timing chart showing an example of a specific control mode in this automatic mode, and the above-mentioned operation will be explained in more detail below with reference to FIG.

In this specific example, it is assumed that the switch 304 corresponding to the remote monitor 3000 handset is first turned on.

In response, receive data including a power-on command is sent to line RDO of channel CHO.

Therefore, the device unit 2 included in the base device 100
0 receives this receive data as described above.

Since this receive data includes a power-on command, the output of the monitoring circuit 210, that is, the retriggerable monostable multivibrator 210c becomes high level.

Therefore, the output PON1 of the OR gate 219 becomes high level, the power supply unit 40 of this base unit 100 is turned on, and power is supplied to the control unit 10.

After that, the control unit 10 sends the channel CH
Poll O's line SDO.

In response to this polling, the remote monitor 300
The status of this monitor 300 is returned as receive data.

At this time, since the power switch 304 for the slave device is turned on, the control unit 10 transmits a power-on command to the line SD2 of the channel CH2.

Accordingly, in the device unit 20' of the slave unit 200 as shown in FIG. 4, the output PON2 of the OR gate 219' is
is considered a high level.

Therefore, the AC power supply section 42' of the power supply unit 40' of the slave device 200 is turned on.

Thereafter, the switch 306 of the remote monitor 300 is turned on in order to use the slave device.

This state is returned to line RDO as receive data in response to polling from control unit 10.

This receive data includes a command to start using the slave device 200.

Therefore, the control unit 10 overrides the selection of the slave unit 200 in response.

In the handset 200, the terminal control section 22' controls the terminal device 30' to be in a usable state based on this send data.

It is assumed that the power switch 303 for the base device 100 is then turned on.

Since the power supply unit 40 of the base unit 100 is already turned on, the turning on of the switch 303 for the base unit is ignored here.

Subsequently, the switch 305 is turned on in the remote monitor 300 in order to use the base unit 100.

In response, receive data including a master unit use start command is returned to line RDO.

In response, the control unit 10 selects the device unit 20 of the base unit 100 via the line SDI of the channel CH1.

The device unit 20, that is, the terminal control section 22 of the base device 100 receives this send data and controls the corresponding terminal device 30 to be in a usable state.

Note that during this time, the control unit 10 also selects the channel CHO at a predetermined timing.

Polling is performed on CHl and CH2, respectively.

Therefore, the AND circuits 210b, 210b' output trigger pulses at predetermined intervals, so that the monostable multivibrators 210c, 210c' maintain a high level output even after being retriggered.

Thereafter, both the terminal devices 30 and 30' of the base device 100 and the slave device 200 become usable.

Thereafter, the operating state is repeated, and the power supplies of the base unit 100 and the slave unit 200 are kept in the on state by polling data for each.

Thereafter, the switch 305 is turned off on the remote monitor 300 in order to stop using the base unit 100.

In response, receive data including a command to stop using the base device 100 is returned to the line RDO.

Therefore, from the control unit 10, the line SD
Send data including this command to discontinue use is sent to I.

Therefore, the terminal control unit 22 sets the terminal device 30 to use based on this send data, that is, the use stop command.

After that, switch 3 for the base unit of the remote monitor 300
03 is turned off.

Therefore, receive data including a command to shut off the power to the base device 100 is sent back to the line RDO.

Therefore, the control unit NO cancels polling SDI for the device unit 20 of the i-machine 100.

Although the receive data RDO includes data indicating that the switch 303 is turned off, the slave unit 200 is still in use, and therefore the power supply unit 40 of the base unit 100 cannot be turned off.

Power to the parent unit is maintained because line RDO is being delivered within predetermined intervals.

This is the control unit 1 included in the base unit 100.
This is because all slave devices are controlled by 0.

After the recording, the switch 306 of the remote monitor 300 is turned off to disable the use of the slave unit.

Therefore, receive data including a command to stop using the handset is returned to line RDO.

Then, in response to the completion of the operation of the slave unit, the control unit 10 sends send data including the cancellation command to the slave unit 200 via channel CH2.

Accordingly, the terminal control unit 22' of the handset 200 controls the terminal 30'
control and discontinue use.

Note that, at this time, if the terminal 30' of the handset 200 is in operation (as can be seen by the control unit 10), it is of course possible to wait for the end of the operation and then stop using it.

The end of use of the handset 200 is detected by the control unit 10 based on the receive data RD2.

After that, the switch 304 of the remote monitor 300 is turned off.

Accordingly, receive data RDO includes data indicating that switch 304 is turned off.

Therefore, the control unit 10 stops polling the slave unit 200.

Accordingly, the device unit 2 of the slave device 200 shown in FIG.
Send data is no longer obtained on the line SD2 connected to 0', and the AND game of the monitoring circuit 210' is
The output of continues to be low level from then on.

Therefore, the output PON2 of the OR gate 219' of the power supply control section 21' becomes low level without the retriggerable monostable multivibrator 210c' being retriggered.

Therefore, A of the power supply unit 40' of this slave device 200
The C power supply section 42' is turned off.

In the control unit 10, the remote monitor 300
Based on the receive data from the base unit 100 and the slave unit 2,
00 is also discontinued after the operation is completed, and it is detected that the power supply is cut off, and polling for channel CH2 is also discontinued.

The receive data from the remote monitor 300 is sent to the switches 303 and 30 of the remote monitor 300.
4 are both turned off, that is, indicating that polling for the remote monitor 300 should be discontinued, so the control unit 10 discontinues polling for this remote monitor 300 as well.

Therefore, response data from this remote monitor 300 is also lost.

This means, for example, that the line R connected to the power supply control section 21 of the device unit 20 of the base unit 100 shown in FIG.
This means that the pulse output of the DO color level is no longer generated, and henceforth the AND game of the monitoring circuit 210)21
The output of 0b becomes low level.

Therefore, the retriggerable monostable multibiflator 210c included in this circuit 210 is not retriggered, and the output PON1 of the OR gate 219 of this power supply control section 21 also becomes low level.

Therefore, the power supply unit 40 of the base unit 100 is also turned off at this point.

In addition, the monitoring circuit 210°210' in the above-mentioned embodiment
In this method, the power-on command is detected by a digital matching circuit, but this is because the power-on command is detected on the line RDO of the receive data from the remote monitor 300, especially when compared to other signals...a signal with many error levels. If this is done, it can be configured in an analog manner using an integrating circuit, a level discrimination circuit, etc.

Note that the power-on command detection circuit 210a is reset as appropriate (the output becomes low level), but in the case of digital, it is only necessary to decode the power-off command from the line SDI.
(Depending on the RDO, the power does not turn off.) In the case of analog, the output of the integrating circuit decreases.

In addition to the banking device described as an embodiment, the present invention can of course be applied to all systems in which a single control unit controls a plurality of input/output crab units.

As described above, according to the present invention, when controlling a plurality of incoming and outgoing crab units with one control unit, the power supply of each incoming and outgoing crab unit is controlled by the send data (control signal) or receive data of this control unit. Therefore, there is no need to individually operate the switches provided for each input/output crab unit to control the power on/off.

Therefore, its operation becomes easy.

Furthermore, when one control unit controls the power supplies of a plurality of input/output crab units, there is no need to provide a signal line for turning the power on and off, and the control unit can be used for both polling data and control signals.

Furthermore, if configured as described above, the device units of the parent unit and slave unit can be shared with the same configuration simply by connecting the line from the remote monitor or not, allowing for standardization and mass production. It becomes possible.
