In the above configuration, since there are four electric wires L1, L1, L2, and L2 between the operation unit 10 and the control unit 20, for example, there is an existing switch box, and this switch box is replaced with the operation unit 10. In this case, the switch box wires (usually four wires of the open signal wire, the close signal wire, the stop signal wire, and the COM wire) can be effectively used as they are without replacement.
In addition, the existing switch box mentioned above should just be equipped with the above existing electric wires at least, The external shape and structures other than the said electric wires are not limited.

  The control unit 20 includes a microcomputer 21 having a CPU and a storage device, an interface 22 for inputting a signal from the operation unit 10 to the microcomputer 21, and inputs and deletes authentication data to the microcomputer 21.

When the registration switch 23 is pressed, the processing by the microcomputer 21 is switched to a registration mode (see FIG. 6) described later.
The erasure switch 24 is used as a means for selectively erasing a plurality of collation data registered in the storage device of the microcomputer 21. When the erasure switch 24 is pressed, processing by the microcomputer 21 will be described later. (See FIG. 6).
The operation mode switch 27 is a switch that enables selection of an operation mode by a push operation from the outside. For example, each time the operation mode switch 27 is pressed, the operation mode is switched.

  Further, the display device 28 is constituted by, for example, a 7-segment LED (see FIG. 3) or other known display devices. This display device 28 is electrically wired to the output terminal of the microcomputer 21 so as to display the operation contents by the registration switch 23, the erase switch 24, the operation mode switch 27, etc., the data in the storage device of the microcomputer 21, and the like.

  Each of the operation modes is a program for causing the CPU of the microcomputer 21 to function, and an appropriate control command is given to the relay circuit 25 in accordance with an input signal by a collation operation by the IC tag 14 or an input operation to the operation switch 11a. Is programmed to output

  The operation restriction data is a variable indicating a condition set for each collation data. If this operation restriction data is expressed visually, a data table as shown in FIG. 10 is obtained.

In FIG. 10, the date and time condition is a condition that limits the date and time when the operation can be performed. According to the illustrated example, the operation can be performed without any date and time restrictions in the case of a circle, and the operation can be performed only on a predetermined date and time in the case of an x mark. The date and time when the verification data is collated is grasped by a clock function or the like provided in the microcomputer 21.
A different date and time may be set for each verification data.

Further, in FIG. 10, the allowable number of times per day condition is a condition for disabling operation when the number of operations per day exceeds a predetermined number. According to the illustrated example, the operation can be performed without limitation on the number of times in the case of a circle, and the operation can be performed a predetermined number of times in the case of an x mark. The number of verifications of authentication data per day is counted by a counter (not shown) of the microcomputer 21.
A different allowable number may be set for each collation data.

In FIG. 10, the registration operation restriction condition is a condition that determines whether or not the user has the authority to register collation data.
Similarly, the erasing operation limiting condition is a condition that determines whether or not the user has the authority to delete the collation data.
The opening operation limiting condition is a condition that determines whether or not the user has the authority to open the shutter device A.

The microcomputer 21 enters the registration mode when the registration switch 23 is turned on, enables input of collation data from the outside, and enters the erase mode when the erase switch 24 is turned on. It is possible to delete the matching data.
Further, the microcomputer 21 enters the normal mode when the registration switch 23 and the erasure switch 24 are not turned on, and the authentication data transmitted from the IC tag 14 based on the operation mode selected by the operation mode switch 27. In addition, an input signal from the outside such as an operation signal by the operation switch 11a is received and the authentication data is compared with the verification data stored in the storage device, or a relay circuit is selected according to the verification result, the operation signal, or the like. 25 is operated.

The relay circuit 25 is an electric circuit including an open relay 25a, a stop relay 25b, a close relay 25c, and the like (see FIG. 4).
The opening relay 25a, the stop relay 25b, and the closing relay 25c are, according to a command from the microcomputer 21, a contact signal for opening the opening / closing body a1 of the shutter device A, a contact signal for stopping the opening / closing body a1, A contact signal for closing the opening / closing body a1 is transmitted to the shutter control panel a32 of the shutter device A, respectively.
The relay circuit 25 may be a general relay having an electromagnetic coil and a contact, for example, but may be configured using a semiconductor element (such as a transistor) having a switching function. .

A specific example of the relay circuit 25 will be described in detail with reference to the electric circuit diagram shown in FIG. 5. The stop relay 25b includes a contact signal that changes from OFF to ON and a contact signal that changes from ON to OFF. It is configured to output two contact signals, and any one of the contact signals is selected according to the electric circuit on the shutter control panel a32 side.
The open relay 25a is configured to output a contact signal that changes from OFF to ON.
The closing relay 25c is configured to output a contact signal that changes from OFF to ON on condition that the opening relay 25a is in an OFF state.
That is, in this electric circuit, when the opening switch 11a1 and the closing switch 11a3 are simultaneously pressed, and the contact of the opening relay 25a and the contact of the closing relay 25c are turned on substantially simultaneously, the opening relay Priority is given to the contact of 25a, and only the contact signal is output.
Therefore, according to this electric circuit configuration, the opening / closing body a1 can be prevented from being closed due to an erroneous operation or the like, and the safety of the shutter device A can be improved.

  Next, processing when the registration switch 23, the erasure switch 24, the operation mode switch 27 and the like are selectively pressed in the switchgear control system 1 will be described in detail with reference to flowcharts shown in FIG.

  First, as shown in FIG. 6, in step 1a, it is determined whether or not the registration switch 23 has been pressed. If the registration switch 23 has been pressed, the process proceeds to step 2a. The process proceeds to step 1b described later.

In step 2a, it is recognized that the microcomputer 21 is in the registration mode, and the display device 28, a voice output device (not shown) or the like can inform the operator or the like that the registration mode has been entered.
Although not shown in the flowchart, when the storage device of the microcomputer 21 is over capacity, the display device 28, the voice output device, etc. output that the registration of the collation data is impossible. Then, the subsequent processing is returned to step 1a.

Next, in step 3a, the control command from the control unit 20 to the relay circuit 25 is disabled.
That is, according to this step 3a, even when an operation signal is input by operating the operation switch 11a or a remote control operation (not shown), the operation signal is invalidated.
Therefore, according to this configuration, during the collation data registration operation to the storage device (collation data storage means) of the microcomputer 21, the opening / closing body a1 is opened, closed, stopped, and the like. It is possible to prevent the control operation from being performed.

  In step 4a, a collation data registration routine (see FIG. 7), which will be described later, is executed, so that collation data is stored in the storage device, and then the process proceeds to step 5a.

  In step 5a, the disabled state of the control command performed in step 3a is canceled, and the process returns to step 1a.

  In step 1b, it is determined whether or not the erasure switch 24 is pressed. If the erasure switch 24 is pressed, the process proceeds to step 2b. If not, the process proceeds to step 1c described later. Transition.

  In step 2b, it is recognized that the microcomputer 21 is in the erase mode, and the display device 28, a voice output device (not shown), etc. can inform the operator that the erase mode has been entered.

In step 3b, the control command from the control unit 20 to the relay circuit 25 is disabled in substantially the same manner as in step 3a.
That is, according to this step 3b, even when an operation signal is input by operating the operation switch 11a or a remote control operation (not shown), the operation signal is invalidated.
Therefore, according to this configuration, the specific operation of the shutter device A such as the opening operation, the closing operation, or the stop of the opening / closing body a1 is performed during the operation of deleting the collation data with respect to the storage device (collation data storage means) of the microcomputer 21. It is possible to prevent the control operation from being performed.

  In step 4b, the designated collation data is erased from the storage device by a later-described collation data erasing routine (see FIG. 8), and then the process proceeds to step 5b.

  In step 5b, the control command disabled state in step 3b is canceled, and the process returns to step 1a.

That is, according to the above steps 3a to 5a and steps 3b to 5b, after entering the registration mode or the erasing mode, the output of the control command based on the operation switch 11a and other operations is disabled, and the collation data registration operation or After the erasing operation, the control command can be output.
Therefore, it is possible to prevent the opening / closing device from performing an unnecessary control operation such as a closing operation or an opening operation of the opening / closing body during the registration data erasing operation or the erasing operation.

In step 1c, it is recognized that the microcomputer 21 is in the normal mode, and the display device 28, a voice output device (not shown) or the like can inform the operator or the like that the normal mode has been set.
Then, in the next step 2c, a control command output routine (see FIG. 11), which will be described later, is executed, and thereafter, the process returns to step 1a.

Next, the flowchart of the collation data registration routine shown in FIG. 7 will be described.
First, in step 11a, the registration flag is turned ON.
This registration flag is a flag indicating that the registration switch 23 has been pressed. Specifically, when the registration switch 23 is pressed, it is stored in the storage device of the microcomputer 21 as a variable such as 1 or 0. The

Next, in step 12a, an authentication time timer t ′ that enables input of authentication data for a predetermined time is started.
In step 13a, the operator or the like is requested to input authentication data through a display on the display device 28, a voice output device (not shown), or the like. An operator or the like inputs authentication data by operating the IC tag 14 close to the operation unit 10.

  In step 14a, it is determined whether authentication data has been input. If it has been input, the process proceeds to the next step 15a, and if not, the process proceeds to step 15b.

  In step 15a, it is determined whether or not the input authentication data matches the verification data stored in the storage device of the microcomputer 21, and if they match, the process proceeds to step 16a. Shifts the processing to step 15b.

  In step 15b, it is determined whether or not the time counted by the authentication time timer is equal to or longer than a predetermined time. If the time is equal to or longer than the predetermined time, the process proceeds to step 24a described later.

  That is, according to the steps 12a to 15b, the verification of the authentication data can be repeated for a predetermined time, and the verification of the authentication data becomes impossible when the predetermined time is exceeded.

Further, in step 16a, it is determined whether or not the verification of the authentication data is performed within the limitation of the date and time condition. If the verification is performed within the limitation, the process proceeds to step 24a. The process proceeds to step 17a.
In step 17a, it is determined whether or not the verification of the authentication data is performed within the limit of the allowable number of times per day. If the verification is performed within the limit, the process proceeds to step 24a, otherwise. In that case, the process proceeds to step 18a.
In step 18a, it is determined whether or not the registration operation restriction condition is not restricted as operation restriction data for the collation data corresponding to the input authentication data. If there is no restriction, the process proceeds to step 19a and the restriction is made. If there is, the process proceeds to step 24a described later.

That is, according to the above steps 16a to 18a, even when the authentication data is collated with the collation data, the registration operation is performed when the condition of the operation restriction data corresponding to the collation data is not satisfied. To refuse.
Therefore, it is possible to prevent the collation data from being registered by an operator or the like who does not have the operation authority.

When it is confirmed in the above step that the condition of the operation restriction data is satisfied, input of registration data is requested in the next step 19a. Specifically, this input request is based on a display on the display device 28, an audio output device, or the like.
Here, the registration data is collation data for collating with the authentication data, and means data in a state before being registered in the storage device of the microcomputer 21.
The means for inputting the registration data will be described in detail. The authentication data stored in the IC tag 14 is used as the registration data, and the registration data is input to the IC tag reader 10a. Yes.
Other means for inputting the registration data may be a specific operation on the control unit 20, a specific operation on the operation switch 11a, an operation with other input devices (not shown), or the like.

  In the next step 20a, it is determined whether or not registration data has been input. If it has been input, the process proceeds to step 21a. If not, the process returns to step 19a.

  In step 21a, the input registration data is stored in the storage device of the microcomputer 21 as new collation data.

  Next, in step 22a, an operation restriction setting routine described later is executed, so that specific operation restriction data is set for the stored new collation data.

In step 23a, it is determined from the state of the registration flag whether or not the registration switch has been pressed again. If it has been pressed, the process proceeds to step 24a. If not, the process proceeds to the above step. Return to 19a.
That is, according to this step 23a, if the registration switch 23 is not pressed again, it is possible to input additional registration data again without verifying the authentication data again.
As another preferred example, a determination may be made between step 22a and step 23a as to whether or not additional registration is to be performed by display on the display device 28 or by an audio output device (flow chart). (Omitted).

  In step 24a, the registration flag is turned OFF to end the collation data registration routine, and the process proceeds to step 5a described above.

Next, the verification data erasing routine shown in FIG. 8 will be described.
First, in step 31a, the erase flag is turned ON.
This erasure flag is a flag indicating that the erasure switch 24 has been pressed. Specifically, when the erasure switch 24 is pressed, it is stored in the storage device of the microcomputer 21 as a variable such as 1 or 0. The

Next, in step 32a, an authentication time timer t ′ that enables input of authentication data for a predetermined time is started.
In step 33a, the operator or the like is requested to input authentication data by the display on the display device 28, the audio output device, or the like. An operator or the like inputs authentication data by operating the IC tag 14 close to the operation unit 10.

In step 34a, it is determined whether authentication data has been input. If it has been input, the process proceeds to the next step 35a, and if not, the process proceeds to step 35b.
In step 35a, it is determined whether or not the input authentication data matches the collation data stored in the storage device of the microcomputer 21, and if they match, the process proceeds to step 36a. Shifts the processing to step 35b.
In step 35b, it is determined whether or not the time counted by the authentication time timer is equal to or longer than a predetermined time. If the time is equal to or longer than the predetermined time, the process proceeds to step 43a described later.

  That is, according to the above steps 32a to 35b, the verification of the authentication data can be repeated for a predetermined time, and the verification of the authentication data is disabled when the predetermined time is exceeded.

In step 36a, it is determined whether or not the verification of the authentication data is performed within the limitation of the date and time conditions. If the verification is performed within the limitation, the process proceeds to 37a. The process proceeds to step 43a.
In step 37a, it is determined whether or not the verification of the authentication data is performed within the limit of the allowable number of times per day, and if it is performed within the limit, the process proceeds to step 38a, otherwise. In that case, the process proceeds to step 43a.
In step 38a, it is determined whether or not there is no restriction on the erasure operation restriction condition as the operation restriction data for the collation data corresponding to the input authentication data. If there is no restriction, the process proceeds to step 39a to restrict If there is, the process proceeds to step 43a described later.

That is, according to the above steps 36a to 38a, even when the authentication data is collated with the collation data, if the condition of the operation restriction data corresponding to the collation data is not satisfied, the erasing operation is performed. To refuse.
Therefore, it is possible to prevent the collation data from being erased by an operator or the like who has no operation restriction.

  When it is confirmed in the above step that the condition of the operation restriction data is satisfied, the next step 39a requests the specification of the collation data to be erased. Specifically, this request is based on a display on the display device 28, an audio output device, or the like.

Here, the specification of the collation data may specifically be a special operation on the control unit 20 or an operation of bringing the IC tag 14 close to the control unit 20.
More specifically, for example, when the registration switch 23 and the erasure switch 24 are pressed at the same time for a predetermined time, it is considered that all stored collation data is designated or the erasure switch 24 is pressed. If authentication data is transmitted from the IC tag 14 during a later predetermined time, it may be assumed that the verification data corresponding to the authentication data is designated.

In the next step 40a, it is determined whether or not collation data has been specified. If so, the process proceeds to step 41a. If not, the process returns to step 39a.
In step 41a, the designated collation data is erased from the storage device of the microcomputer 21.

Next, in step 42a, it is determined from the state of the erasure flag whether or not the erasure switch 24 has been pushed again. If it has been pushed, the process proceeds to step 43a. If not, the process is carried out. Return to step 39a.
That is, according to this step 42a, if the erasure switch 24 is not pressed again, the verification data can be additionally deleted again without verifying the authentication data again.
As another preferable example, a determination may be made between step 41a and step 42a as to whether or not to perform additional erasure by display on the display device 28 or by the audio output device (flow chart). (Omitted).

  In step 43a, the erasure flag is turned OFF to end the collation data registration routine, and the process proceeds to the above-described step 5b (see FIG. 6).

Next, the operation restriction setting routine shown in FIG. 9 will be described.
First, in step 51a, it is determined whether or not there is an operation restriction on the authentication data input in step 14a (see FIG. 7).
Specifically, with respect to the collation data stored in the control unit 20 corresponding to the authentication data, whether the various operation restriction data (see FIG. 10) set for the collation data are all in an unrestricted state. It is determined whether or not.
If there is any operation restriction on the operation restriction data, the process proceeds to step 52a, and if not, the process proceeds to step 51b.

In step 52a, operation restriction data identical to that of the authentication data input in step 14a is set for the collation data stored in step 21a (see FIG. 7), and the process proceeds to step 23a (see FIG. 7). Return processing.
That is, according to this step 52a, the operation restriction of the IC tag 14 used for authentication is also applied to the newly registered IC tag 14.

In step 51b, the operator is requested whether or not to add an operation restriction by display on the display device 28 or a sound output device.
In step 52b, if it is determined that an operation restriction is added based on a response from the operator, the process proceeds to the next step 53b, and if not, the process proceeds to step 52c.

In step 53b, the operator is requested to input a date / time condition by a display on the display device 28, a voice output device, or the like, and the date / time condition input by the operator in response to the request is displayed in step 21a (FIG. 7). Set for the collation data stored in (Ref.).
Similarly, in the next step 54b, the operator is requested to input a permissible number of times condition per day, and the permissible number of times condition inputted per day from the operator in response to the request is set to the above step 21a ( This is set for the collation data stored in FIG.

  In addition, according to the example shown in FIG. 10, the date and time conditions and the allowable number of times conditions are “unlimited (◯)” and “limited (×)” for a specific date and time condition and allowable number of conditions set in advance. Either one is selected, but as another example, an arbitrary date and time range and allowable number of times are input, or one of a plurality of types of date and time ranges and allowable number of times is selected. You may make it.

Next, in step 55b, the operator is requested to input registration operation restriction conditions by display on the display device 28, a voice output device, or the like, and the operation restriction data input by the operator in response to the request is obtained. It sets with respect to the collation data memorize | stored in the said step 21a (refer FIG. 7).
In other words, in this step 55b, the operator is requested to determine whether or not to restrict the registration operation to the collation data, and the operation restriction data (no restriction (◯) or Restricted (x)) is set corresponding to the collation data.

Similarly, in step 56b, the operator is requested to input the erasure operation restriction condition, and the operation restriction data (no restriction or restriction) input from the operator in response to the request is received in step 21a (FIG. Set for the collation data stored in step 7).
Further, in step 57b, the operator is requested to input the opening operation restriction condition, and the operation restriction data (no restriction or restriction) inputted from the operator in response to the request is inputted to the step 21a (see FIG. 7). ) Is set for the collation data stored in (1).

In step 52c, the operation limit is set to unlimited for the collation data stored in step 21a (see FIG. 7).
More specifically, in this step 52c, various operation restriction data corresponding to the collation data in the data table of FIG. 10 are all set to “no restriction (◯)”.

  Then, after the operation restriction data is set as described above, the processing by the microcomputer 21 returns to step 23a (see FIG. 7).

Next, the flowchart of the control command output routine shown in FIG. 11 will be described.
First, in step 61a, an authentication time timer t 'that enables input of authentication data for a predetermined time is started.
In step 62a, the operator or the like is requested to input authentication data by the display on the display device 28, the sound output device or the like. An operator or the like inputs authentication data by operating the IC tag 14 close to the operation unit 10.

  In step 63a, it is determined whether authentication data has been input. If it has been input, the process proceeds to the next step 64a, and if not, the process proceeds to step 64b.

In step 64a, it is determined whether or not the input authentication data matches the verification data stored in the storage device of the microcomputer 21, and if they match, the process proceeds to step 65a. Shifts the processing to step 64b.
In step 64b, it is determined whether or not the time counted by the authentication time timer is equal to or longer than a predetermined time. If the time is equal to or longer than the predetermined time, the process proceeds to step 1a (see FIG. 6). .

  That is, according to the steps 61a to 64b, the verification of the authentication data can be repeated for a predetermined time, and the verification of the authentication data is disabled when the predetermined time is exceeded.

Next, in step 65a, it is determined whether or not the verification of the authentication data is performed within the limitation of the date and time conditions. If the verification is performed within the limitation, the process proceeds to step 66a. Returns to step 1a (FIG. 6).
In step 66a, it is determined whether or not the verification of the authentication data is performed within the limit of the allowable number of times per day. If the verification is performed within the limit, the process proceeds to step 67a, otherwise. In that case, the process returns to step 1a (FIG. 6).

In the next step 67a, it is determined whether or not the collation data corresponding to the input authentication data has no restriction on the opening operation restriction condition as the operation restriction data. If there is no restriction, the process proceeds to step 68a. If there is a limit, the process proceeds to step 67b.
In step 67b, only the opening operation is set to be invalidated, and the process proceeds to step 68a.

  That is, according to the above-described steps 65a to 67b, even when the authentication data is collated with the collation data, if the condition of the operation restriction data corresponding to the collation data is not satisfied, the shutter device A described later is applied. Reject or partially restrict operations.

Next, in step 68a, the operation valid time timer T is reset to 0 seconds and started.
In step 69a, the light emitter 11j starts to emit light.
Therefore, in this state, the operator can visually confirm that the IC tag 14 has been collated by the light emission of the light emitter 11j, and even if the surroundings are dark, The operation switch 11a can be visually recognized by light emission.

Next, in step 70a, only an operation without a limiting condition among the opening operation, the closing operation, and the stopping operation with respect to the shutter device A is validated.
According to an example of the present embodiment, operations other than the opening operation invalidated in step 67a, that is, the closing operation and the stopping operation are validated.
These operations are operations performed on the operation mode selected by the operation mode switch 27.

The operation mode includes, for example, a mode in which an opening command, a closing command, a stop command, etc. are sequentially issued every time the IC tag 14 is brought close to the operation unit 10, or the operation switch 11 a of the operation unit 10. A mode in which a command selected from among an open command, a close command, and a stop command is issued according to the operation, a mode in which a specific operation command is issued by a transmission signal from a remote controller (not shown), and others These modes are stored in advance in the storage device of the microcomputer 21 as one or more types of programs, and are selected by operating the operation mode switch 27.
According to step 70a, in the selected operation mode, operations other than the opening operation disabled by step 67a are enabled.

  Then, in step 71a, it is determined whether or not the count by the operation effective time timer has reached a predetermined time or more. If the time has reached the predetermined time or more, the process proceeds to the next step 72a. Then, the process returns to step 69a.

  Next, in step 72a, all operations, that is, an opening operation, a closing operation, and a stopping operation are invalidated. Note that, for an emergency stop or the like, the stop operation alone may not be invalidated and may be kept valid.

  In step 73a, the light emitter 11j is turned off, and the processing by the microcomputer 21 is returned to step 1a (see FIG. 6).

That is, according to the above steps 68a to 73a, an operation without a limiting condition (the closing operation and the stop operation according to the illustrated example) can be repeatedly performed within the set time, and the time has elapsed. Later, it can be made inoperable.
In step 71a, even when the count by the operation valid time timer does not exceed the predetermined time, the process may be shifted to the next step 72a on condition that the operation without the limiting condition is performed. Is possible.

  Further, according to the above embodiment, the registration switch 23 and the erasure switch 24 are operated to enter the registration mode and the erasure mode. However, as another example, input of specific authentication data is possible. In such a case, the mode may be specified such as the registration mode or the erasure mode without operating the registration switch 23 or the erasure switch 24.

  Further, according to the above embodiment, the registration switch 23 is operated in order to enter the registration mode. Furthermore, when no authentication data is stored in the collation data storage means, Regardless of whether or not the registration switch 23 is operated, the registration mode may be automatically entered.

Further, according to the above-described embodiment, the control command is restricted in the same manner in the registration mode and in the erasure mode (see steps 3a and 3b). Different control commands may be used for the registration mode and the erase mode.
Further, according to the above-described embodiment, as an example of the restriction of the control command, the control command cannot be output (see Steps 3a and 3b). It is also possible to output a control command for cutting off the power supply.

  Further, according to the above embodiment, as shown in FIG. 7, the registration data is input after the specific authentication data is collated, but before the specific authentication data is collated. After being input and confirming the collation, the invalid state may be changed to the valid state.

Further, as a function added to the above embodiment, a stop command or an open command may be output for a predetermined time (for example, 0.5 seconds) during the registration mode and / or the erasure mode.
In this aspect, for example, the stop command or the release command may be output for the predetermined time immediately after the start of the registration operation or the deletion operation by the registration switch 23 or the deletion switch 24. According to this configuration, since the opening / closing body of the opening / closing device can be stopped or opened immediately after the start of the registration operation or the erasing operation, the safety of the opening / closing device can be improved.
Further, in this aspect, when the authentication data is collated, the stop command or the release command may be output for a predetermined time. Also, in order to improve the safety of the switchgear, the authentication data Regardless of the verification, the stop command or the release command may be output for a predetermined time.
In this aspect, it is also possible to output a stop command or an open command for a predetermined time (for example, 0.5 seconds) after limiting the control command to be temporarily disabled.

In addition, as a function added to the above embodiment, a stop command may be continuously output during the registration mode and / or the erasure mode.
That is, in the control circuit of a general switchgear, the stop command is prioritized over the close command or the open command.
Therefore, in such a switchgear, if a stop command is continuously input, even if a close command or an open command is input during the input of the stop command, the stop command has priority, so the switch body is stopped. Can be maintained in a state. Even if the opening / closing body is operating when the registration mode or the erasing mode is entered, the opening / closing body can be stopped.

  Further, as a function added to the above-described embodiment, a signal indicating an operation state of the opening / closing body a1 in the opening / closing apparatus A is input to the control unit 20, and the opening / closing body a1 is registered before the registration operation or the erasing operation by the signal. When it is confirmed that is operating, it is possible to prevent the registration operation and / or the deletion operation from being performed.

Further, as a function added to the above embodiment, when a specific operation such as pressing the registration switch 23 and the erasure switch 24 is performed at the same time, the registration process and the erasure process are performed almost simultaneously ( For example, all the collation data stored in the collation data storage means may be deleted, and new collation data input immediately after that may be registered.
