Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an opening / closing system and can be applied to, for example, a shutter, a door, a window, an overhead door, a gate, a gate (a gate such as a parking lot), a roll screen (for example, a light shielding curtain), a blind, an awning device, and the like.
[0002]
[Prior art]
There are many electric shutters that use a motor as a power source to open and close the shutter. For example, according to the rotation of the rotating shaft of the motor, the control unit receives and counts the number of encoder pulses that are output, and opens and closes it. The movement distance and position of the shutter at the time are recognized, and the rotation operation of the motor is stopped at the timing when the count value is a predetermined value. When the opening operation or the closing operation is stopped, the number of shutter operations is incremented by 1 (see Patent Document 1). The updated number of shutter operations is displayed on a display unit having a 7-segment LED, LED matrix, or the like provided in the shutter case or the operation unit.
[0003]
[Patent Document 1]
JP, 2000-54766, A In general, some shutters provided in a factory, a factory entrance, and the like have a considerably larger number of shutter operations per day than other shutters. It is preferable to display the information because it is possible to accurately recognize the maintenance time and the like.
[0004]
[Problems to be solved by the invention]
However, the user should be aware of the displayed number of shutter operations only after the maintenance and inspection period is approaching to a certain extent. It can be said that there is a waste of power consumption.
[0005]
Also, if the number of shutter operations is always lit, the user will look closely and the user may be bothered. In addition, there is an open / close system that displays an error code on the display when normal open / close operations are not performed, but due to the updated display of the number of shutter operations, the user viewed from a distance misunderstood the error code display. The display may be confused by recognizing the update of the number of shutter operations for the first time near the display.
[0006]
There is an open / close system that always displays the operation status, operation state, and the like of other open / close bodies on the display unit, but has the same problem as described above.
[0007]
Therefore, there is a demand for an opening / closing system that can reduce power consumption when updating the display items and can reduce discomfort to the user by updating the display items.
[0008]
[Means for Solving the Problems]
In order to solve this problem, the present invention provides an open / close system that opens and closes an open / close body , (1) an operation count measuring means for measuring the number of operations of the open / close body, and (2) a display means for displaying the operation count. , (3) when the updated operation count is one of several predetermined number is displayed by the display means, the updated operation number have a display control unit that does not appear in other than the predetermined number of times, (4) The difference between the two predetermined times before and after the phase is selected to be smaller as the predetermined number is larger .
[0009]
DETAILED DESCRIPTION OF THE INVENTION
(A) First Embodiment Hereinafter, a first embodiment in which the opening / closing system according to the present invention is applied to a shutter opening / closing system will be described in detail with reference to the drawings.
[0010]
(A-1) Configuration of First Embodiment FIG. 1 is a block diagram showing an electrical configuration of a shutter opening / closing system according to the first embodiment.
[0011]
In FIG. 1, the opening / closing system 1 of the first embodiment includes an operation unit 2, a control unit 3, a motor 4, a pulse encoder 5, and a display unit 6.
[0012]
One end of the shutter 7 is attached to the rotating shaft of the motor 4 or a cylindrical body that covers the rotating shaft by an attachment member, and the shutter 7 moves in the opening direction or the closing direction by the forward / reverse rotation of the motor 4. In addition, the motor 4 is stopped when the motor 4 is stopped.
[0013]
The motor 4 is, for example, one that can rotate forward and reverse. The motor 4 may be any of a direct current motor, a synchronous motor, an induction motor, and the like.
[0014]
A pulse encoder 5 is provided directly or indirectly on the rotating shaft of the motor 4. For example, the case where it is indirectly provided corresponds to the case where the pulse encoder 5 is provided on the winding shaft of the shutter 7 when the winding shaft of the shutter 7 is different from the rotation shaft of the motor 4.
[0015]
The pulse encoder 5 outputs a predetermined number of pulses per rotation of the rotating shaft of the motor 4, and its generation principle is not questioned, such as a magnetic type or an optical type. The pulse encoder 5 may output a count value obtained by counting pulses instead of outputting a pulse.
[0016]
The operation unit 2 performs an operation for instructing an operation desired by the user, such as an opening operation, a closing operation, and a stopping operation of the shutter 7. As the operation unit 2, for example, a push button type can be applied. In the case of the opening / closing system 1 to which the remote control system is applied, a remote control receiver is also included in the operation unit 2 here instead of the operation unit 2 or in addition to the operation unit 2. In addition, the operation unit 2 is a concept that includes a component that is not operated by a user. For example, the concept of the operation unit 2 of the first embodiment is such that an output of a sensor that detects that the automatic guided vehicle has passed a predetermined position in a predetermined direction becomes an activation instruction for an opening operation or a closing operation. Is included. Further, for example, when the timing device automatically issues an opening operation or closing operation instruction when the time measured by the timing device reaches a predetermined time, this timing device is also the operation unit of the first embodiment. It is included in the concept of 2. Further, for example, when there is a host computer that manages the entire building or individual shutters, when the host computer issues a start instruction for an opening operation or a closing operation based on a predetermined time or a predetermined event occurrence, This higher-level computer is also included in the concept of the operation unit 2 of the first embodiment.
[0017]
The display unit 6 includes, for example, a 7-segment LED, an LED matrix, and the like, and displays the number of shutter operations and the like under the control of the control unit 3. The display unit 6 may be configured as a unit fused with the operation unit 2. Further, the display unit 6 may be wired or wirelessly communicated with the control unit 3. The attachment position of the display unit 6 is arbitrary, but in the first embodiment, it is assumed that the user can confirm the display contents without opening the lid or the like.
[0018]
When an operation of the shutter 7 is instructed from the operation unit 2, the control unit 3 controls the motor 4 to execute the operation. When the instructed operation is an opening operation or a closing operation, the control unit 3 performs control while also using the output of the pulse encoder 5. The control unit 3 displays the number of shutter operations on the display unit 6 under a predetermined condition.
[0019]
The control unit 3 includes, for example, a CPU 10, a ROM 11, a RAM 12, an EEPROM 13, and a motor drive circuit 14.
[0020]
The motor drive circuit 14 rotates the motor 4 in the instructed direction or stops the rotation state under the control of the CPU 10.
[0021]
The CPU 10 executes a program stored in the ROM 11 according to an instruction operation by the operation unit 2 while using the fixed data of the ROM 11 and the EEPROM 13 and the storage data of the RAM 12 and using the RAM 12 as a working memory. Thus, the operation of the shutter is controlled and the display control by the display unit 6 is executed. The CPU 10 includes a configuration for counting the pulses of the pulse encoder 5. The CPU 10 also includes a timer 10a that measures a predetermined time.
[0022]
The ROM 11 stores various processing programs executed by the CPU 10 and fixed data used at that time. The ROM 11 also stores, for example, a closing operation control program 11C shown in FIG. 2, which will be described later, and an operation frequency forced display program 11D, which is shown in FIG. 3 which will be described later.
[0023]
The RAM 12 is appropriately used when the CPU 10 executes a certain processing program, and also stores predetermined data that is appropriately updated as necessary.
[0024]
The EEPROM 13 stores fixed data that can be changed. For example, the EEPROM 13 also stores a reference value group of count values obtained by counting the pulses of the pulse encoder 5 relating to the shutter operation count 13a and the shutter 7 opening operation, closing operation, and stop operation.
[0025]
Note that the number of shutter operations 13a stored in the EEPROM 13 is determined by a maintenance inspector or the like according to a predetermined procedure for the operation unit 2 or a dedicated reset switch (for example, a push switch; not shown). It can be cleared to 0 by an operation or the like.
[0026]
(A-2) Operation of the First Embodiment Next, the control operation when the shutter 7 of the opening / closing system 1 of the first embodiment is closed will be described with reference to FIG.
[0027]
When the closing operation instruction signal is given from the operation unit 12 in the fully opened state where the shutter 7 is stopped, the CPU 10 starts the closing operation control program 11C shown in FIG.
[0028]
First, the CPU 10 instructs the motor drive circuit 14 to rotate the motor 4 in the direction in which the shutter 7 is lowered, and the motor drive circuit 14 drives the motor 4 as such (S1).
[0029]
A pulse is output from the pulse encoder 5 by the rotation of the motor 4, and the CPU 10 sets the shutter position count value stored in the EEPROM 13 before the rotation of the motor 4 as an initial value, and every time a pulse is given from the pulse encoder 5, The current position count value is decremented by 1, and it is awaited that the current position count value becomes the stop position when the shutter 7 stored in the EEPROM 13 is fully closed (S2).
[0030]
In addition, although control etc. which decelerate a motor with the value of the present position count value are also performed, since it leaves | separates from the characteristic of 1st Embodiment, it abbreviate | omits. Further, a forced stop may be caused by operating the stop instruction key of the operation unit 2, but it is omitted because it is away from the features of the first embodiment.
[0031]
When the current position count value reaches the stop count reference value, the CPU 10 instructs the motor drive circuit 14 to stop the rotation of the motor 4, and the motor drive circuit 14 stops the motor 4 (S3).
[0032]
Thereafter, the CPU 10 takes out the number of shutter operations 13a stored in the EEPROM 13, increments it by 1 and stores it again in the EEPROM 13, and also stores it in the RAM 12 (S4). Then, after starting the timer 10a which measures a predetermined time (for example, 5 seconds) (S5), the number of shutter operations updated by the display unit 6 is displayed (S6).
[0033]
During this display, the CPU 10 waits for the timer 10a to expire (S7). When the timer 10a expires, the display of the number of shutter operations on the display unit 6 is terminated, and the shutter on the RAM 12 is also displayed. The number of operations is also erased (S8).
[0034]
Next, a forced display operation of the number of shutter operations in the opening / closing system 1 of the first embodiment will be described with reference to FIG.
[0035]
When a forced display instruction signal for the number of shutter operations is given from the operation unit 12, the CPU 10 starts an operation number forced display program 11D shown in FIG.
[0036]
Here, the operation on the operation unit 12 for instructing the forced display of the number of shutter operations should be special so that unnecessary display operations such as simultaneous pressing of the opening operation instruction key and the stop operation instruction key are not performed. Is preferred. Note that a dedicated key for forced display may be provided on the operation unit 12.
[0037]
When starting the operation number forced display program 11D, the CPU 10 first extracts the shutter operation number 13a stored in the EEPROM 13 and stores it in the RAM 12 (S11).
[0038]
Thereafter, a display operation similar to the display operation during the closing operation is performed. That is, after starting the timer 10a (S12), the CPU 10 displays the number of shutter operations on the display unit 6 (S13). When the timer 10a times out (S14), the display unit 6 displays the number of shutter operations. The number of shutter operations on the RAM 12 is also deleted (S15).
[0039]
(A-3) Effects of First Embodiment According to the opening / closing system 1 of the first embodiment, the number of shutter operations is the predetermined time (for example, 5 seconds) by the timer 10a from the time when the shutter is fully closed. Since the display is performed, the display time can be significantly reduced as compared with the conventional case, and the power consumption for display can be suppressed. When the display unit 7 is battery driven, the above effect is particularly significant.
[0040]
In addition, since the display is performed only for a predetermined time from the time when the fully closed state is reached, the user can determine that the number of shutter operations is displayed even if he is far away, and it is not necessary to bother to move to the vicinity of the display unit 7. is there. When it is desired to confirm the number of shutter operations after the light is turned off, the number of shutter operations can be confirmed by performing an instruction operation for forced display, and there is no inconvenience due to display for a predetermined time.
[0041]
Further, in the case where the display unit 12 is also used for displaying an error, the error display has no display time limit. Therefore, the display of the number of shutter operations and the error display can be distinguished depending on the lighting time even if they are far away. It is possible to move to the vicinity of the display unit 7 only when an error is displayed.
[0042]
(B) Second Embodiment Next, a second embodiment in which the opening / closing system according to the present invention is applied to a shutter opening / closing system will be described with reference to the drawings.
[0043]
The entire configuration of the opening / closing system of the second embodiment can also be represented in FIG. 1 according to the first embodiment described above.
[0044]
The second embodiment is slightly different from the first embodiment in the operation executed in accordance with the closing operation control program 11C.
[0045]
FIG. 4 is a flowchart showing an operation executed according to the closing operation control program 11C in the second embodiment, and the same reference numerals are assigned to the corresponding steps in FIG. 2 according to the first embodiment described above. As shown.
[0046]
The process (S1 to S4) from when the closing operation instruction signal is given from the operation unit 12 to when the closing operation control program 11C shown in FIG. It is the same.
[0047]
Thereafter, the CPU 10 determines whether the updated number of shutter operations matches any of a plurality of types of predetermined times (S20).
[0048]
FIG. 5 is an explanatory diagram of a predetermined number of times used for matching determination. FIG. 5 shows an example in which the minimum number of shutter operations from the previous maintenance check to the next maintenance check is 10,000.
[0049]
When the number of shutter operations is 9000 or less, a multiple of 1000 (1000, 2000,...) Is a predetermined number. When the number of shutter operations is 9001 to 9900, a multiple of 100 (9100, 9200,...) Is a predetermined number of times. In the range of the number of shutter operations from 9901 to 9990, a multiple of 10 (9910, 9920,...) Is a predetermined number, and when the number of shutter operations is 9991 or more, it is determined that all match the predetermined number. Is done.
[0050]
If the updated number of shutter operations does not match any predetermined number, the CPU 10 erases the number of shutter operations on the RAM 12 and ends the series of processes (S21).
[0051]
On the other hand, if the updated number of shutter operations matches any one of the predetermined times, the CPU 10 performs the same number of shutter operations that match the predetermined number of times as in the first embodiment. Display is executed (S5 to S8).
[0052]
In the case of the second embodiment, the number of displayed shutter operations is limited (1000, 2000,..., 9000, 9100, 9200,..., 9900, 9910, 9920,..., 9990, 9991,. ) The display time may be longer than that of the first embodiment. Further, when the display is activated, a buzzer or the like may be sounded to alert the user that the display is being performed.
[0053]
The same effect as that of the first embodiment can be obtained by the opening / closing system of the second embodiment. In the case of the second embodiment, since the number of shutter operations to be displayed is limited, a reduction in power consumption can be expected more than in the first embodiment.
[0054]
(C) Third Embodiment Next, a third embodiment in which the opening / closing system according to the present invention is applied to a shutter opening / closing system will be described with reference to the drawings.
[0055]
The overall configuration of the opening / closing system 1B of the third embodiment is substantially the same as that of the first embodiment described above, but a display mode switch 15 is additionally provided in the control unit 3 as shown in FIG. It has been.
[0056]
In the case of the third embodiment, as a display mode, a constant display mode in which the number of shutter operations is always displayed, and a low power consumption display for a predetermined time after updating as described in the first embodiment described above. Mode, and can be switched by the display mode switch 15. The display mode switch 15 is a push switch, for example, and each time the display mode switch 15 is operated, the display mode is switched to the other display mode. As shown in FIG. 6, the EEPROM 13 stores the currently selected display mode 13b. When the display mode switch 15 is operated, the CPU 10 displays the display mode 13b stored in the EEPROM 13 on the other side. The mode is rewritten (the flowchart is omitted).
[0057]
In the third embodiment, since there are two types of display modes, the operation executed in accordance with the closing operation control program 11C is slightly different from that in the first embodiment.
[0058]
FIG. 7 is a flowchart showing an operation executed according to the closing operation control program 11C in the third embodiment, and the same reference numerals are given to the same and corresponding steps as in FIG. 2 according to the first embodiment described above. As shown.
[0059]
The process (S1 to S4) from when the closing operation instruction signal is given from the operation unit 12 to when the closing operation control program 11C shown in FIG. It is the same.
[0060]
Thereafter, the CPU 10 recognizes which display mode is currently selected (S30).
[0061]
If the currently selected display mode is the constant display mode, the CPU 10 displays the number of shutter operations updated by the display unit 6 and ends the series of processes (S31).
[0062]
On the other hand, if the currently selected display mode is the low power consumption mode, the CPU 10 displays the updated number of times of the shutter operation for a predetermined time in the same manner as in the first embodiment (S5 to S8). ).
[0063]
Even in the switching system of the third embodiment, when the low power consumption mode is selected, the same effect as that of the first embodiment can be obtained.
[0064]
In addition, according to the third embodiment, since two types of display modes are prepared and the user can select them, the user can arbitrarily select the display mode, and the usability is improved. For example, when the number of shutter operations approaches the maintenance inspection time (the standard number of shutter operations requiring maintenance inspection), the user switches from the low power consumption mode to the normal display mode so that the maintenance inspection can be performed. It becomes possible to judge the time more reliably.
[0065]
