DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in a remote monitoring and control system that transmits a transmission signal to a signal line by a time division multiplex transmission system and enables load control by operating a switch using the transmission signal. The present invention relates to a setting device for a remote monitoring control system that sets a correspondence between a switch and a load.

[0002]

2. Description of the Related Art A remote monitoring control system having a configuration shown in FIG. 14 is conventionally known (for example, Japanese Patent No. 278).
No. 1003). In this remote monitoring control system, a plurality of operation terminals 31 and control terminals 32 are connected (multidrop connection) to a two-wire signal line Ls connected to the transmission control device 30. Although only one control terminal 32 is shown in the illustrated example, a plurality of control terminals 32 are actually used. Here, a feed line is generally adopted as a connection form between the operation terminal 31 and the control terminal 32 and the signal line Ls. That is, the operation terminal device 31 and the control terminal device 32 have two sets of terminals for connection to the signal line Ls, and the signal line Ls is connected to each terminal, so that the signal line Ls is connected to the operation terminal device 31 or the control terminal. Container 32
Is extended through. In the illustrated example, the operation terminal device 31 is used.
As an individual switch 31a, a pattern switch 31b
Is provided, and a pattern setting unit 33 described later is also connected to the signal line Ls. Individual addresses are set in each of the operation terminals 31 and each of the control terminals 32, and the transmission control device 30 individually recognizes the operation terminals 31 and the control terminals 32 using those addresses. The individual switch 31a and the pattern switch 31b have switches Sa and Sb, respectively, and the control terminal 32 is connected to a relay Ry for controlling a load. The operation terminal 31 is provided with a confirmation light (not shown) made of a light emitting diode for confirming the operation state of the relay Ry. Here, in general, a latching type relay is used as the relay Ry, and when the control terminal 32 operates the relay Ry, power is supplied from the transformer T to the relay Ry in a pulsed manner.

[0003] The transmission control device 30 controls the signal line Ls
The transmission signal Vs of the format shown in FIG. That is, a synchronization signal SY indicating the start of signal transmission, mode data MD indicating the mode of the transmission signal Vs, address data AD for individually calling the operation terminal 31 and the control terminal 32, and control data for controlling the relay Ry and the load. CD, checksum data C for detecting transmission errors
S, a bipolar (± 24V) time-division multiplexed signal consisting of a signal return period WT which is a time slot for receiving a return signal (monitoring data) from the operation terminal device 31 or the control terminal device 32, Data is transmitted (FIG. 15B). In each of the operation terminals 31 and the control terminals 32, when the address data AD transmitted by the transmission signal Vs received via the signal line Ls matches the preset address, the control data CD is transmitted from the transmission signal Vs. At the same time, the monitoring data is returned as a current mode signal (a signal transmitted by short-circuiting the signal line Ls via a suitable low impedance) during the signal return period WT of the transmission signal Vs.

A desired operation terminal 3 is transmitted from the transmission control device 30.
When transmitting data to the control terminal 32 or the control terminal 32, a transmission signal Vs with the mode data MD as the control mode and the address of the operation terminal 31 or the control terminal 32 as address data AD is transmitted. Vs to the signal line Ls
, The operation terminal device 31 or the control terminal device 32 that matches the address data AD receives the control data CD and returns the monitoring data during the signal return period WT. The transmission control device 30 confirms that the control data CD has been transmitted to the desired operation terminal 31 or control terminal 32 based on the relationship between the transmitted control data CD and the monitoring data received during the signal return period WT. The control terminal 32 outputs a load control signal for controlling the relay Ry according to the received control data CD, and the operation terminal 31 outputs a monitoring signal for displaying the operation confirmation of the relay Ry according to the received control data CD. I do.

On the other hand, the transmission control device 30 normally transmits a transmission signal Vs in which the mode data MD is in the dummy mode at regular time intervals (constant polling). When transmitting information, an interrupt signal as shown in FIG. 15C is generated in synchronization with the synchronization signal SY of the transmission signal Vs in the dummy mode. At this time, the operation terminal 31 sets an interrupt flag to prepare for the subsequent information exchange with the transmission control device 30. When the transmission control device 30 receives the interrupt signal, it sets the mode data MD to the interrupt polling mode and sets the upper half of the address data AD (address data A).
The transmission terminal transmits the transmission signal while sequentially increasing the upper 4 bits (where D is 8 bits), and the upper 4 bits of the address data AD of the transmission signal in the transmission mode of the interrupt polling mode are transmitted in the operation terminal 31 which generates the interrupt signal. When it matches the upper 4 bits of the address set in the operation terminal 31, the lower half bits of the address are returned to the transmission controller 30 during the signal return period WT. Thus, the transmission control device 30
Can search the operation terminals 31 that have generated the interrupt signal at a time, so that the operation terminals 31 can be found in a relatively short time.

When the transmission control device 30 obtains the address of the operation terminal device 31 that has generated the interrupt signal, the mode data M
D is set to the monitoring mode, and a transmission signal having the acquired address data AD is transmitted to the signal line Ls. In response to this transmission signal, the operation terminal device 31 returns information to be transmitted to the signal return period WT. It is. Finally, the transmission control device 30 sends a signal instructing an interrupt reset to the operation terminal device 31 that has generated the interrupt signal, and releases the interrupt flag of the operation terminal device 31. As described above, information transmission from the operation terminal device 31 to the transmission control device 30 is performed by four signal transmissions from the transmission control device 30 to the operation terminal device 31 (dummy mode, interrupt polling mode, monitoring mode,
(Interrupt reset). When the transmission control device 30 wants to know the desired operating state of the control terminal 32, it is only necessary to transmit a transmission signal using the mode data MD as monitoring data.

The above operation will be briefly summarized. First, when input data is generated by operating the switches Sa and Sb,
When the monitoring data corresponding to the input data is returned from the operation terminal 31 to the transmission control device 30 and the transmission control device 30 transmits the control data CD to the control terminal 32, the control terminal 3
2 controls the relay Ry by outputting a load control signal. Here, the load monitoring input is given to the control terminal 32, the monitoring data corresponding to the load monitoring input is returned to the transmission control device 30, and the returned monitoring data is transmitted to the operation terminal 31. The operation terminal 31 outputs a monitoring signal according to the transmission signal. The monitoring output is usually used to turn on and off the confirmation lamp. The individual switch 31a has a maximum of four switches Sa, and the control terminal 32 can control a maximum of four relays Ry. The individual switch 31a and the control terminal 32 include each switch Sa and relay Ry. A 2-bit load number is added for individual recognition. Hereinafter, the address of the individual switch 31a to the control terminal 32 will be referred to as a channel, and the channel and the load number will be collectively referred to as an address. That is, each switch Sa, Sb and each relay Ry (or load) are given an individual address. In addition, by setting the individual switch 31a and the control terminal 32 corresponding to each other one-to-one to the same channel, the correspondence can be easily understood (actually, the distinction between the operation side and the control side is made according to the channel number). For example, the upper few bits of the address data indicate the operation side or the control side, and the lower several bits are used as a channel.)

In this type of remote monitoring control system, the transmission control device 30 manages the correspondence between the address of the pattern operation Sb and the address of the relay Ry. If the addresses of the relays Ry (or loads) of a plurality of circuits are associated with each other as related data,
It is possible to control the relays Ry of a plurality of circuits collectively by b. Such collective control includes group control and pattern control. In the group control, a plurality of loads are controlled to the same control state, and in the pattern control, the plurality of loads are controlled to control states individually set in advance. The group control and the pattern control are particularly effective when the load controlled by the relay Ry is a lighting load. In a place where a large number of lighting loads are arranged like an office space, a plurality of lighting loads are used. The group control and the pattern control can be used when turning on and off all at once. In the illustrated example, the pattern switch 31b including the switch Sb
, But does not show a group switch which is a terminal device for group control. However, the pattern control and the group control are the same as other operation terminals except that an operation address defined for collective control is used.

As described above, in order to perform pattern control, the transmission control device 30 controls the pattern switch 31b.
The relay R of a plurality of circuits is connected to the address of the switch Sb provided in the
It is necessary to register the address of y in association with it, and this type of setting operation is called pattern setting. Since the same applies to the case of group control, a setting operation for performing group control is hereinafter referred to as group setting.

The remote monitoring control system has two operation modes, a control mode for controlling the relay Ry and a setting mode for performing pattern setting and group setting. That is, when the remote monitoring control system is operated, the transmission control device 30 first enters a normal control mode, and sends a transmission signal in the dummy mode to the signal line Ls. If there is no interrupt signal, the polling is continuously performed by repeating the transmission signal in the dummy mode. On the other hand, when there is an interrupt signal, the operation terminal 31 is specified and a request from the operation terminal 31 is fetched. If the change of the operation mode is not requested, the current operation mode is determined, the relay Ry is controlled in the control mode, and the pattern setting or the group setting is performed in the setting mode. When a change of the operation mode is requested, the operation mode is changed according to the request.

To set a pattern in the setting mode,
The switch Sb of the desired pattern switch 31b is operated, and then the switch Sa associated with the relay Ry to be controlled by the switch Sb is operated. Here, it is assumed that the relationship between each switch Sa and the relay Ry is set first. According to such a procedure, the state of the relay Ry according to the operation of the switch Sa is taken into the transmission control device 30 as related data, and the state of a plurality of relays Ry is associated with one switch Sb. Group setting is almost the same as pattern setting.

On the other hand, in this type of remote monitoring control system, a pattern setting device 33 which is a kind of the operation terminal device 31 may be used. The pattern setting device 33 corresponds to a device in which a plurality of operation terminals 31 are provided in one device, and includes a large number of switches S (the illustrated example includes switches S for 64 circuits. The configuration is such that the switch S is used to select the operation for each of the four circuits, so that the operation can be performed for each of the four circuits.
Each switch S can be used as any switch by assigning an address.

When using the pattern setting device 33, the pattern mode switch 35 is operated to instruct the pattern setting mode, the switch S assigned as a pattern switch is selected, and then each switch is operated by operating the switch S assigned as an individual switch. The control state of Ry is set to create related data, and the related data is transferred to the transmission control device 30. That is, since the related data can be created at the place where the pattern setting device 33 is installed, the operation is simplified as compared with the case where the pattern setting is performed using the individual switch 31a and the pattern switch 31b.

[0014]

However, since the pattern setting device 33 is provided with the switches S for 64 circuits as described above, it is large and expensive, and is usually fixed to a control panel or the like. used. In other words, it is not suitable for use in a small- to medium-scale remote monitoring and control system (that is, a system in which the number of operation terminals 31 and control terminals 32 is relatively small).
At the time of group setting or pattern setting, the pattern setting device 33 is operated at a place different from the load setting place, and it is difficult to perform pattern setting and group setting work while checking the control state of the load. is there. Further, when the pattern setting device 33 is used, pattern setting and group setting are relatively easy.
Providing 3 increases the cost. In addition, the pattern setting device 33 is usually used only at the time of construction, and is rarely used thereafter. Therefore, even if the pattern setting device 33 is connected in the system, it may be useless.

The operation mode of the setting unit 34 includes four modes of an address setting mode, a pattern group setting mode, an initial setting mode, and a special mode, and these modes are selected by pressing keys K21 to K24. Key K21 is for address setting mode, key K22 is for pattern
The group setting mode, the key K23 correspond to the initial setting mode, and the key K24 corresponds to the special mode. That is, the key K21
To K24 are selectively pushed.

When the address setting mode is selected by operating the key K21, an address or function data can be set in the data storage section of each terminal by an optical wireless signal. When the address setting mode is selected,
The marker M corresponding to the character of "address setting" is highlighted. In addition, as described in the background art, since one terminal has four load numbers, one terminal has one load number.
On the screen, setting columns for four addresses are displayed in four rows at the top and bottom. The setting column has five columns on the left and right, and has cells of four rows and five columns. To change the contents of each cell, the desired cell may be displayed in a highlighted state. To reverse the cell, the cursor key K14 is used.

The cursor key K14 is a cross key indicating up, down, left and right directions of movement, and when a part corresponding to a desired direction is pressed, the position of the inverted display moves in that direction. When the address type (cell in the first column) is individual, the address (cell in the second column) is displayed by combining a channel number and a load number with a hyphen, and the channel number and the load number are each It is highlighted separately. In other words, when the position of the inverted display is moved by the cursor key K14, the channel number and the load number are displayed separately in an inverted manner.

The terminal type is selected from group switches, pattern switches, individual switches, and dimming switches by depressing the keys K21 to K24 in a state in which the cells in the first column are highlighted. can do. When the first column is highlighted, the terminal type can be changed by operating the page key K15. The page key K15 is a key for instructing up and down two directions. When an up and down direction is instructed, the terminal type is sequentially displayed.

In a state where the inside of the second column is highlighted, the numerical value displayed in the second column can be changed by pressing the page key K15.
For example, when the channel number is highlighted, the channel number can be increased or decreased by the up / down page keys K15, and when the load number is highlighted, the load number can be increased or decreased. When the pattern type is the pattern (P) or the group (G), the pattern number or the group number which is the identifier of the related data can be changed by the page key K15 in a state where the address is highlighted. Further, if the address clear key K12 is pressed while the address cell is highlighted, the address can be erased.

When the cells in the third column are highlighted, the page key K1 is used to determine whether to turn the load on or off.
5 is selected, but such an operation is effective only in pattern setting and group setting. When the cell in the fourth column is highlighted, the page key K
15 allows the user to specify temporary ON and delay OFF, and the time is also selected. In other words, 30 seconds for temporary on,
One minute, five minutes, 60 minutes, and 120 minutes can be selected. When the delay is off, 30 seconds, one minute, and five minutes can be selected. Specifically, the combination of the type of operation and the time, such as temporary ON for 30 seconds, temporary ON for one minute,..., Are sequentially selected by the page key K15. When the grid in the fifth column is highlighted, the dimming level is selected by the page key K15. This cell is valid when the pattern type is dimming. When the operation unit of the operation terminal device 31 for which this setting is made is operated to turn on the illumination load associated with the operation unit. For example, the lighting load can be turned on at a specified dimming level. The execution key K16
Can be used to determine the settings of one cell, and the cancel key K17 can be used to delete the settings of one cell.

After the address setting of one screen is completed by the above-described operation, the setting device is set so that the transmission and reception of the optical wireless signal can be performed only with the terminal device to which the address and the function data are set. If the user presses the key K13 while bringing the terminal 34 close to the terminal, a wireless signal can be transmitted to the terminal, and the settings on the screen can be stored in the data storage unit of the terminal. When setting the contents of another terminal, the above operation can be repeated. However, if the forward key K18 is pressed, the address (channel number) can be set.
The same setting content can be displayed on the screen P of the liquid crystal display by shifting only one (incrementing one).

In the address setting mode,
If the confirmation key K11 is pressed while the setting device 34 is close to the terminal device, the setting contents of the data storage section of the terminal device are read out and displayed on the screen P of the liquid crystal display.
Therefore, in the case of the existing remote monitoring and control system,
After confirming the contents of the data storage unit with the confirmation key K11, an address or function data may be set. By such an operation, it is also possible to use the contents already set. At this time, the type of the terminal is also displayed on the screen P of the liquid crystal display.

The operation terminal 31 having a switch can be used as any of an individual switch, a pattern switch, a group switch, and a dimmer switch. Is connected to an operation terminal device 31 having a switch
And must be distinguished. In addition, the relay terminal 32a and the dimming control terminal 32c must be distinguished. In the address setting mode, it is possible to change the type of the device for which the address is set, but this processing will not be described in detail. The device type for which the address is set is indicated by the position of the marker M that moves along the lower side of the screen P of the liquid crystal display.

After the address and function data are set in each terminal as described above, pattern setting and group setting become possible. That is, when the pattern setting mode is selected by the key K22, a screen as shown in FIG. 5 is displayed. At this time, the marker M corresponding to the character of "pattern setting" is displayed in reverse video. In this state, key K
By pressing the key 31 or the key K32, it is possible to select between group setting and pattern setting. Alternatively, even if the page key K15 is operated in a state where the cells in one row and one column are highlighted, it is possible to select between group setting and pattern setting. Further, if the page key K15 is operated after determining whether the setting is the group setting or the pattern setting with the execution key K16, the group number and the pattern number can be designated. The illustrated example shows a state where the pattern number is 1, and “P1” is displayed in one row and one column. The contents of the pattern setting are stored in the RAM of the signal processing unit 20, and when an external storage device is connected, the contents registered in the external storage device can be read. The keys K33 and K34
Is operated when individually setting an address for each terminal device or when setting for dimming, but is not a gist and will not be described.

The group setting is a setting for performing collective control so that the state of each load becomes equal, and can be said to be a special case in which the state of each load is individually set as in the case of pattern setting. explain. In the pattern setting mode, the first column shows the pattern number,
Whether or not there is a fade is displayed, indicating whether or not the load connected to one terminal is designated to be turned on or off collectively. These contents can be specified by operating the page key K15 in a state where the corresponding cell is highlighted. For fade, no fade, fade 3
Seconds, fades of 5 seconds, and fades of one minute can be specified. For batch ON / OFF of loads, no batch, batch ON, and batch OFF can be specified. The address is displayed in the second column,
For the address, enter only the channel number Page key K
15 can be specified. Further, the same setting as the address setting can be performed for the third to fifth columns.

As described above, in the pattern setting mode, the content for each terminal can be set. The illustrated example shows an example in which the same pattern number is assigned to a plurality of load numbers by one terminal, but even if a procedure of assigning the same pattern number to a plurality of terminals is adopted, it belongs to the pattern number. The load can be controlled collectively.
When pattern setting is performed for each terminal device, the setting contents are stored in the signal processing unit 20. Therefore, by referring to the content stored in the signal processing unit 20, it is possible to know whether or not a pattern has been set for each terminal device. Therefore, when the pattern setting is completed for one terminal and the forward key K18 is operated to select the terminal of the next channel, if the pattern has already been set for the terminal, the buzzer Bz , A warning sound is generated, and a confirmation display is made on the screen P of the liquid crystal display as to whether or not overwriting can be performed. Here, if the forward key K18 or the execution key K16 is operated, it is overwritten and the cancel key K
When the button 17 is operated, the change of the contents of this channel is stopped. To end the pattern setting, the setting key K13 is operated.

When the key K23 is operated, the setting device 3
In the initial setting mode for setting various functions of No. 4, the marker M is highlighted and displayed at the position corresponding to the character of "initial".
When the initial setting mode is selected, it is possible to set whether or not to sound the buzzer Bz in accordance with the operation of the operation unit 13, the contrast of the screen P of the liquid crystal display, the type of the transmission control device 30, and the initial special setting. Become. The presence or absence of the buzzer Bz is selected by the page key K15, and the contrast is displayed as a bar graph, and the stage is set by the page key K15. The type of the transmission control device 30 is selectable because there are various products in the transmission control device 30 and a procedure for transferring related data defining the contents of pattern setting and group setting to the transmission control device 30. This is because the form of the transmission signal is different. Specifically, the model number of the transmission control device 30 is selected by the page key K15. The cursor key K14 is used to move between the setting fields.

By the way, in the initial special setting, it is possible to select three contents of an erroneous registration prevention mode, a power-off time, and a change in the number of connected terminals, and a field of the initial special setting is selected by a cursor key K14 and a page key K15. By operating, it is possible to make settings according to the contents.

When the erroneous registration prevention mode is selected, it is possible to prevent addresses not used in the system from being included in the pattern setting and the group setting when setting the pattern and the group. That is, the RAM of the signal processing unit 20
By referring to the setting contents, it is possible to prevent an address that does not exist in the remote monitoring control system from being included in the pattern setting or the group setting.

When the battery disconnection time is selected, it becomes possible to select whether or not to turn off the power after a lapse of a specified time after the keys are no longer operated (using the execution key K16 and the cancel key K17). In this case, the time can be set (using the page key K15).

When the monitoring of the change in the number of connected terminals is selected, it is selected whether or not to monitor the change in the number of terminals connected to the signal line Ls (the execution key K16 and the cancel key K1).
7 is used). In this function, the state of the terminal is read into the RAM of the signal processing unit 20, and when the number of terminals changes based on the data on the RAM, the address of the added or deleted terminal is displayed on the screen of the liquid crystal display. P
To be displayed. That is, if this function is used, it is easy to find a portion where the connection between the terminal device and the signal line Ls is unstable.

When the special mode is selected by operating the key K24, the marker M is highlighted at the position of the character "special". In the special mode, each mode is selected by operating the execute key K16 after selecting the four modes of data transfer, checking, editing, and setting by operating the page key K15.

In the data transfer, the transfer partner of the related data is
This is a mode for selecting whether to use the transmission control device 30 or the memory card 29. By operating the execution key K16 after selecting with the page key K15, the transfer partner can be determined. Checks include a system status display that indicates the operating status of the remote monitoring and control system, operation confirmation whether the remote monitoring and control system actually operates using the set related data, and display of an unused address in the remote monitoring and control system. In addition, the remote monitoring control system has a function of displaying whether or not the address of each terminal device is used for pattern setting or group setting (referred to as terminal registration display). When edit is selected, inversion, copy, delete, and range designation input become selectable. As for the selection, the execution key K16 is operated in a state where a desired item is selected by the page key K15 as in the above-described example. As the setting state, it is possible to select whether the remote monitoring control system is set to a normal state in which load control is performed or a setting state in which related data is set in the transmission control device 30. These operations are not essential and will not be described in detail.

At the lower part of the screen P of the liquid crystal display in the setting unit 34, a figure I indicating the battery B is displayed together with the notation "remaining battery power". In the figure I, the remaining amount of the battery B is shown. The remaining amount of the battery B is represented by a state where the inside of the figure I is filled as shown in FIG. 6A and a state where half of the figure I is filled as shown in FIG. (A) shows a state where the remaining amount of the battery B is sufficient. In addition, it may take 30 to 40 minutes to transfer the relevant data to the transmission control device 30, and if the remaining battery power runs out during such operation, the operation is wasted. The state of ()) means that this kind of processing cannot be performed. If the capacity of the battery is further reduced, the power is forcibly shut off regardless of what kind of processing is performed. At the bottom of the screen P of the liquid crystal display, a figure H indicating the on / off state of the backlight is also displayed. Since the turning on / off of the backlight is indicated by this graphic H, the turning on / off of the backlight can be known regardless of the surrounding illuminance. Further, since this display is shown without providing a separate indicator light, it is possible to avoid an increase in cost such as providing an indicator light.

In order to display the remaining battery level as described above, in this embodiment, as shown in FIG. 7, two voltage detection circuits DV1 and DV2 each composed of an integrated circuit are used. Each of the voltage detection circuits DV1 and DV2 includes a switch SW2
The output voltage of the battery B is compared with a reference value via the control circuit. When the output voltage of the battery B is higher than the reference value set in each of the voltage detection circuits DV1 and DV2, the output is opened. It is configured. The reference value of the voltage detection circuit DV1 is set lower than the reference value of the voltage detection circuit DV2. The outputs of both voltage detection circuits DV1 and DV2 are pulled up by pull-up resistors R1 and R2 via diodes D1 and D2. If the output is open, connection between diodes D1 and D2 and pull-up resistors R1 and R2. The point goes to the H level. Since the output voltage of the battery B varies depending on the operation state of the internal circuit, the signal processing unit 20
Is periodically detected when the input is in a state of accepting an input from the key matrix 24, thereby preventing variations in the detected voltage due to a difference in operation state.

Thus, the dual voltage detection circuits DV1 and DV2
When both outputs are open, the graphic I indicating the remaining battery level becomes the state shown in FIG. 6A, and the voltage detection circuit DV1
When only the output of FIG.
The state shown in FIG. The central processing circuit 20 performs a process of changing the graphic I displayed on the screen P of the liquid crystal display based on the outputs of the voltage detection circuits DV1 and DV2.

Hereinafter, the configuration of the power supply circuit 27 will be described in detail. The power supply circuit 27 in the present embodiment basically has a configuration shown in FIG. As described above, the power supply circuit 27
Has a function of supplying power generated from a transmission signal transmitted through the signal line Ls to the internal circuit, and a function of supplying power from the battery B to the internal circuit. Since the transmission signal received by the transmission / reception circuit 21 is a bipolar signal, the transmission signal is full-wave rectified by the rectifier 41 and smoothed by the smoothing circuit 42, thereby generating a DC voltage higher than the output voltage of the battery B. You. The rectifier 41 and the smoothing circuit 42 constitute a front power supply circuit, and the output voltage of the front power supply circuit and the output voltage of the battery B are input to the constant voltage circuit 43 through the diodes D3 and D4, respectively. Here, since the output voltage of the front power supply circuit is higher than the output voltage of the battery B, when power is supplied from the signal line Ls by the transmission signal and the output voltage is obtained in the smoothing circuit 42, the diode D4 is turned off. When the output voltage of the smoothing circuit 42 is lower than the output voltage of the battery B, the diode D4 is turned on and power is supplied from the battery B to the constant voltage circuit 43. Is supplied. That is, both diodes D3 and D4 function as a power supply switching circuit. The constant voltage circuit 43 outputs a voltage (for example, 5 V) necessary to supply power to the internal circuit.

The smoothing circuit 42 is a series control type constant voltage circuit as shown in FIG. 9, and includes a current limiting resistor R3 inserted between the rectifier 41 and the diode D3 and a collector of the transistor Q1.・ Equipped with a series circuit with the emitter,
It has a known configuration in which a connection point between the resistor R4 and the Zener diode ZD1 connected between the output terminals of the rectifier 41 is connected to the base of the transistor Q1, and a smoothing capacitor C1 is connected to the output terminal. Further, the constant voltage circuit 43 includes a switching regulator. The reason why a switching regulator is used for the constant voltage circuit 43 is that the loss between the input and the output is smaller than that of the series control type constant voltage circuit, and that the output voltage of the battery B is lower than the output voltage of the constant voltage circuit 43. This is because a desired output voltage can be obtained by boosting. Therefore, a polarity inversion type switching regulator capable of both boosting and stepping-down operation is used for the constant voltage circuit 43. Here, since a high frequency noise is generated from the switching regulator, the signal line Ls is provided by providing a smoothing circuit 42 using a series control type constant voltage circuit.
Noise can be suppressed. Also,
Since the output voltage of the smoothing circuit 42 can be easily adjusted, the loss amount can be adjusted by adjusting the difference between the input and output voltages of the smoothing circuit 42.

Since the power conversion efficiency of the switching regulator is 70 to 80%, the power conversion efficiency is set to 70%, the output voltage of the smoothing circuit 42 is set to 10 V, and the output voltage of the constant voltage circuit 43 is set to 5 V. Then, the input current with respect to the output current X to the internal circuit is (X × 5) /
(10 × 0.7) ≒ 0.71X. Constant voltage circuit 43
When the output current is X, the input current is also X when X is a series control type. Therefore, it can be said that the use of a switching regulator increases the power use efficiency by at least about 30%. In addition, an increase in the temperature of the constant voltage circuit 43 due to an increase in the power conversion efficiency is also suppressed.

As described above, when the switching regulator of the polarity inversion type is used as the constant voltage circuit 43, a desired voltage can be obtained by boosting even when the output voltage of the battery B is lower than the output voltage of the constant voltage circuit 43. Therefore, the input voltage of 5.5 V is required in the case of the series control type, while the configuration of the present embodiment can be used up to 3 V, for example. That is, as shown in FIG.
The usable period can be extended by the period T until the voltage drops from 5V to 3V.

In the present embodiment, the battery B can be used as the power source, so if the power is forgotten to be turned off, the battery B will be consumed. Therefore, the power supply is cut off when the operation unit is not operated at all within the specified time. The signal processing unit 20 determines whether or not the operation unit (key matrix 24) has been operated within the specified time. If the operation unit has not been operated, an auto-off signal is output from the terminal G of the signal processing unit 20. You. That is, the signal processing unit 20 functions as an auto-off unit.

A circuit that receives an auto-off signal from the terminal G of the signal processing unit 20 and shuts off power supply to the internal circuit is shown in FIG.
As shown in FIG. 1, the power supply circuit 27 is provided. That is,
The constant voltage circuit 43 is provided with an on / off control terminal for selecting an output voltage generation state and an output voltage stop state by an external signal (when the integrated circuit is used as the constant voltage circuit 43, an on / off control terminal is used) ), The signal to the on / off control terminal is controlled using the auto-off signal from the terminal G of the signal processing unit 20.

This will be described more specifically. Constant voltage circuit 43
Is connected to a series circuit of a pnp-type transistor Q2 as a first switch element and a resistor R5, and an on / off control terminal is connected to a connection point between the collector of the transistor Q2 and the resistor R5. . The base of the transistor Q2 is connected to a connection point between the resistor R6 and the collector of an npn-type transistor Q3 as a second switch element, and the signal processing unit 20 is connected to the base of the transistor Q3.
, An L-level auto-off signal is supplied from the terminal G. The output terminal of a reset circuit 44 composed of an integrated circuit is also connected to the base of the transistor Q2 via a resistor R7. The reset circuit 44 has an output terminal grounded before the power is turned on, and is configured to open the output when the power is turned on. The capacitor C2 is also connected between the output terminals of the reset circuit 44.

However, before the power is turned on, the reset circuit 4
4 is grounded, the capacitor C
2 has no charge, and when the switches SW1 and SW2 are turned on and the power is turned on, the output of the reset circuit 44 is opened, so that the capacitor C2 starts to be charged through the resistors R6 and R7. Until the charging of the capacitor C2 proceeds, the transistor Q2 is turned on because the emitter-base voltage of the transistor Q2 is relatively large. As a result, the voltage between both ends of the resistor R5 becomes substantially equal to the input voltage to the constant voltage circuit 43, the input to the on / off control terminal becomes H level, and the constant voltage circuit 43 operates. That is, power supply to the internal circuit is started, and power is also supplied to the signal processing unit 20.
When power supply to the signal processing unit 20 is started, the signal processing unit 2
0 turns the signal applied from the terminal G to the base of the transistor Q3 to H level to turn on the transistor Q3. Since the transistor Q2 can be turned on while the transistor Q3 is on regardless of the voltage across the capacitor C2, the constant voltage circuit 43 continuously generates the output voltage.

On the other hand, when the operation section is not operated for a predetermined time, an L-level auto-off signal is output from the terminal G of the signal processing section 20.
3 turns off. At this time, since the capacitor C2 is charged, the transistor Q2 is turned off, the on / off control terminal of the constant voltage circuit 43 becomes L level, and the power supply from the constant voltage circuit 43 to the internal circuit stops. Thus, the power supply to the signal processing unit 20 is also stopped.

To turn on the power again after the supply of power is stopped by the auto-off signal, the switches SW1 and SW
2 may be turned on after being turned off. That is, when the switches SW1 and SW2 are turned off, the output terminal of the reset circuit 44 is grounded and the capacitor C2 is discharged. Therefore, when the switches SW1 and SW2 are turned on again, the internal operation of the constant voltage circuit 43 is performed by the above operation. Power supply to the circuit can be resumed.

The power switch 15 as the switches SW1 and SW2 is a slide switch, and is exposed on the side surface of the body 11, so that when the setting device 34 is housed in a tool box or the like, it comes into contact with other members. By doing so, the possibility that the power switch 15 is turned on can be reduced.

In the above example, the reset circuit 44 was used to form a circuit for stopping the power supply from the constant voltage circuit 43 to the internal circuit in response to the auto-off signal. It is also possible to realize an auto-off configuration by using a switch SW3 having a mechanical contact as shown in FIG. The switch SW3 is a momentary type push button switch (a switch whose contact is turned on only during a pressing operation).
3 can be used. This circuit is
A series circuit of the switch SW3 and the resistor R5 is connected to a constant voltage circuit 4
3, the connection point between the switch SW3 and the resistor R5 is connected to the on / off control terminal of the constant voltage circuit 43, and the auto-off signal from the terminal G of the central controller 20 is supplied to the on / off control terminal. Is what it is.

In this configuration, when the switch SW3 is turned on, the on / off control terminal of the constant voltage circuit 43 becomes H level, so that the power supply from the constant voltage circuit 43 to the internal circuit is started, and the signal processing unit 20 The signal from the terminal G becomes H level. That is, power is continuously supplied from the constant voltage circuit 43 to the internal circuit. Thereafter, when the operation section is not operated for a predetermined time, an L-level auto-off signal is output from the terminal G of the signal processing section 20. At this time, since the switch SW3 is off, an L-level auto-off signal is input to the on / off control terminal of the constant voltage circuit 43, and the power supply from the constant voltage circuit 43 to the internal circuit is stopped. That is, it is possible to operate in the same manner as the circuit configuration shown in FIG. Further, in the circuit configuration shown in FIG. 12, since a switch to be pressed such as a rubber switch can be used, the switch SW3 can be formed at the same time as the rubber switch forming the key matrix 24. It leads to reduction.

By the way, in the circuit configuration shown in FIG.
When the time during which the switches SW1 and SW2 are turned on after being turned off is very short, the capacitor C2 is not sufficiently discharged, and the supply of power from the constant voltage circuit 43 to the internal circuit starts when the switches SW1 and SW2 are turned on. It may not be done. Therefore, a circuit configuration as shown in FIG. 13 may be adopted. This circuit comprises two resistors R8, R9 and npn
A series circuit of the transistor Q5 is connected between the input terminals of the constant voltage circuit 43, and a connection point between the resistor R9 and the collector of the transistor Q5 is connected to an on / off control terminal of the constant voltage circuit 43. Also, pnp transistors Q4 and Q2
The series circuit with the resistors R10 and R11 is also a constant voltage circuit 43.
Connected between the input terminals. The connection point between the two resistors R8 and R9 is connected to the base of the transistor Q4.
The connection point between 0 and R11 is connected to the base of the transistor Q5. Further, a signal from a terminal G of the signal processing unit 20 is supplied to a connection point between the transistor Q4 and the resistor R10 through a diode D5. This circuit is a kind of latch circuit. When a signal from a terminal G goes to H level, both transistors Q4 and Q5 are turned on, and a diode D
3, the state is maintained by itself until the power supply through D4 is stopped.

In this circuit configuration, the switches SW1, SW
When the power is turned on by turning on the second transistor 2, both transistors Q4 and Q5 are both off.
H level is input to the on / off control terminal of the constant voltage circuit 43 through R9, and power supply to the internal circuit is started.
At this time, the output of the terminal G of the central processing circuit 20 is set to be at the L level. That is, when power is supplied from the constant voltage circuit 43 to the internal circuit, the transistors Q4, Q4
5 are both kept off. Thereafter, when the state where the operation unit is not operated continues for a prescribed time, the signal processing unit 20 outputs an H level from the terminal G and turns on both transistors Q4 and Q5. When the transistor Q5 is turned on, the input to the on / off control terminal of the constant voltage circuit 43 becomes L level, so that the power supply from the constant voltage circuit 43 to the internal circuit is stopped. When the power supply from the constant voltage circuit 43 to the internal circuit stops, the output of the terminal G of the central processing circuit 20 stops.
Since the transistors Q4 and Q5 turn on each other, the input to the on / off control terminal of the constant voltage circuit 43 is kept at L level. That is, even with this configuration, the stop of the power supply by the auto-off signal is realized.
