FIG. 4 is a diagram showing a connection configuration, FIG. 4 is a diagram showing a connection configuration between a shutter opening / closing device and an I / F unit that is a part of a reading unit, including a circuit configuration, and FIG. FIG. 6 is a flowchart showing a first reading procedure of shutter control information in the example, and FIG. 7 is a second reading procedure of shutter control information in the example. FIG. 8 is a diagram showing waveforms of various signals used in the control in the example. FIG. 9 is a waveform showing a structure of history data as an example of control information output by the shutter opening / closing device. It is.

  As shown in FIG. 1, a shutter 1 is attached to an opening 5 of a building that leads to the outside. The shutter 1 is configured by connecting a large number of slats, and is wound around a driving shaft (not shown) in the upper case 4 when opened by the driving force of the motor 3 of the opening / closing device 2 transmitted through an interlocking mechanism (not shown). The opening 5 is closed by being unfolded and lowered when closed.

  As shown in FIG. 2, the switchgear 2 of this example is connected to a power source 7 via a power connector 6. As shown in FIG. 1, the power source 7 is led from the room of the building.

  As shown in FIG. 2, the opening / closing device 2 of this example has a CPU 8 as a control means. The control action based on various operations, information processing, and the like by the opening / closing device 2 is performed by the CPU 8 processing information such as various signals input from the outside based on a program described in advance and data stored in advance. It can be grasped as an operation for outputting a control signal and controlling the drive of the motor 3 to be controlled.

  As shown in FIG. 2, the opening / closing device 2 includes a motor 3 that opens and closes the shutter 1. The driving of the motor 3 is controlled by the CPU 8 via the motor driving circuit 9. In the opening / closing device 2, a push button switch 10 as an operation means is connected to the CPU 8 via a push button switch connector 11. As shown in FIG. 1, the push button switch 10 is installed in a building room. When an operation signal from the push button switch 10 is input to the CPU 8 via the push button switch connector 11, the CPU 8 drives the motor 3 via the motor drive circuit 9 to open and close the shutter 1.

  When the motor 3 is started in the opening direction or the closing direction, the CPU 8 counts the number of opening and closing of the shutter 1 and outputs an opening / closing number value signal. That is, every time the motor 3 is started, the CPU 8 determines the driving direction (whether the shutter 1 is opened or closed) and counts the number of times cumulatively. In the closing direction, the number of times of opening / closing that indicates how many times the motor 3 has been started is output as a signal.

  As shown in FIG. 2, the opening / closing device 2 includes a nonvolatile memory 12 such as an EEP-ROM as storage means. The non-volatile memory 12 stores the number of opening / closing of the shutter 1 as shutter control information by the opening / closing number value signal sent from the CPU 8. That is, the cumulative number of times of opening / closing since the installation of the shutter 1 is stored as control information. Specifically, the total number of operations in the opening direction, the number of operations in the closing direction, and the number of opening and closing operations.

  Here, every time the CPU 8 raises or descends the shutter 1 counts once, it counts once. Therefore, if the shutter 1 is changed from the closed state to the open state while repeatedly starting and stopping, The number of opening operations is many.

  The reason for counting each time the motor 3 is started is that the motor 3 consumes the most power at the time of starting and the motor 3 itself is also worn out, so that such a counting method is effective as monitoring information during maintenance. Note that the number of stops may be counted each time a stop signal is input. This is because the stop operation also puts a load on the motor 3 and causes wear, so it is worth counting as monitoring information during maintenance.

  As shown in FIG. 2, the opening / closing device 2 includes, as abnormality detection means for detecting an abnormality in opening / closing of the shutter 1, motor protection means 13 such as a thermal protector, obstacle detection means 14 of the shutter 1, and lower limit. It has a pair of electric locks 15 as position detecting means.

  The motor protection means 13 such as a thermal protector senses a temperature rise due to overheating of the motor 3 and outputs an abnormality occurrence signal as shutter control information to the CPU 8.

  As the obstacle detection means 14, a load detection means for detecting the load of the motor 3 from a current value or the like, or a detection sensor for optically detecting the foreign object when a foreign object is caught in the shutter 1 can be adopted. The kind and principle are not ask | required. When there is an abnormality, the motor protection means 13 and the obstacle sensing means 14 output an abnormality occurrence signal as shutter control information and send it to the CPU 8.

  The electric lock 15 is connected to the CPU 8 via the electric lock connector 16. As shown in FIG. 1, the electric locks 15 are installed in pairs on both lower sides of the shutter 1 and are means for detecting the lower limit position of the shutter 1 in order to control the driving of the motor 3.

  When the CPU 8 receives an abnormality occurrence signal from the abnormality detection means exemplified above, the CPU 8 determines from the signal what kind of abnormality has occurred, and outputs an abnormality occurrence content signal indicating the content of the abnormality that has occurred. .

  The nonvolatile memory 12 stores the type of abnormality generated by the abnormality occurrence content signal sent from the CPU 8 in association with the number of times the motor 1 is opened in the opening or closing direction at the time of occurrence. That is, for example, when an abnormality occurrence signal is received from a thermal protector, an abnormal temperature rise of the motor 3 due to some cause occurs, for example, when the motor 3 is started 500 times in the opening direction. It is stored in the nonvolatile memory 12 as control information.

In addition, the abnormalities (operations / operations / activities, etc.) stored in association with the shutter control information in the opening / closing device 2 and the number of times of opening / closing at the time of occurrence are listed as follows. Conceivable.
1) The operation of reversing the operation of the shutter 1 by sensing the load by the load sensing means, and the number of times of opening and closing when the operation occurs.
2) The operation of reversing the operation of the shutter 1 by the operation of the electric lock 15, and the number of times of opening and closing when the operation occurs.
3) Manual open / close operation and the number of open / close operations during the operation.
4) The fact that the electric lock 15 is activated when the manual closing operation is performed at high speed, and the number of times of opening and closing when the electric lock 15 is activated.
5) Thermal protector operation and the number of open / close operations during the operation.
6) The occurrence of a power failure and the number of opening and closing times when the power failure occurs.

  As shown in FIG. 2, the opening / closing device 2 is provided with a bidirectional HA terminal 17 capable of input / output, and is connected to an HA system 18 (home automation system) which is an external control system. . As shown in FIG. 1, the HA terminal 17 is pulled out and installed in a building room.

  The HA (home automation) system is a system that comprehensively controls the opening and closing, locking and unlocking of windows and the like, control of air conditioning equipment, lighting on and off, etc. in a building. It becomes a control target of the HA system. That is, the HA system can control the opening / closing of the shutter 1 by sending a control signal from the bidirectional HA terminal 17 to the CPU 8 of the shutter opening / closing device 2. Conversely, the HA system can also receive a control signal (monitor signal) indicating the current state of the shutter 1 from the CPU 8 of the shutter opening / closing device 2 from the bidirectional HA terminal 17 and use it for control in the HA system.

  As shown in FIGS. 1 and 2, a reading device 20 for reading shutter control information stored in the nonvolatile memory 12 is detachably connected to the HA terminal 17 of the switchgear 2. For example, if the control information is shutter history information or the like, the reading device 20 is used by a worker who visits the building for maintenance work of the switchgear 2 to extract reference information on the maintenance work of the shutter. can do.

  The reading device 20 is a device that connects to the HA terminal 17 in the building room as required. Specifically, as shown in FIG. 3, the reading device 20 is connected to an I / F unit 30, a portable personal computer, a PAD, and the like. It can be constituted by the reading means 40 consisting of the above.

  In the personal computer or PAD that is the reading means 40, the type of abnormality that has occurred in the past, which is the shutter control information, and the number of opening / closing operations at the time of occurrence of the abnormality, which is the shutter control information (how many times in the opening direction or how many in the closing direction) Control information accumulated and stored in the non-volatile memory 12 over time can be read from the non-volatile memory 12 connected to the CPU 8 via the I / F unit 30. The reading means 40 is provided with a control information acquisition button 41 as a starting means when performing this reading operation.

  The I / F unit 30 is an interface for connecting a personal computer or a PAD as the reading means 40 having a communication standard different from that of the HA system to the HA terminal 17 of the shutter opening / closing device 2.

  The HA terminal of the HA system is stipulated in detail in the Japan Electrical Manufacturers' Association standard JEM 1427 (established on June 5, 1987, revised on March 22, 1994). For example, as shown in FIGS. 4 and 5, the HA terminal basically has four connection lines, and these connection lines are used for applications such as power input, control input, monitor output, and abnormal output, for example. Is done. FIG. 5 shows the circuit configuration of the connection terminal portion of the HA system 18 connected to the HA terminal 17 of the shutter.

  According to the standard, the terminal voltage of the HA terminal must be 30 VDC or less, and the insulation performance is specified in detail. The control signal has a pulse conduction time of 200 to 300 ms, a pulse interval of 200 ms or more, and a response time of 350 ms or less. When the monitor signal is a dynamic signal, the dynamic signal period is 20 ms or less, the dynamic signal conduction period is 1 ms or more, and the ratio of the dynamic signal conduction period / dynamic signal period is 0.15 or more.

  In contrast to the HA terminal of such a standard, in the personal computer or PAD as the reading means 40, the standard of the cable or connector in the communication system is RS232C or USB, and the signal is also different from the signal used in the HA system. .

  In order to connect the I / F unit 30 to the HA terminal 17 of the shutter opening / closing device 2, an opening / closing HA connector 31 connected to the HA terminal 17 of the shutter opening / closing device 2 is provided as shown in FIGS. The HA terminal 17 of the shutter opening / closing device 2 is connected to the HA system cable 25. Further, the I / F unit 30 has an RS232C or USB standard terminal 32 as shown in FIG. 3 in order to connect to a personal computer or PAD as the reading means 40 having a communication standard different from that of the HA system as described above. Then, the cable 26 according to these standards is connected to the terminal of the reading means 40.

  In addition, the I / F unit 30 is provided with a switch 33 as a starting means when performing reading operation of shutter control information when the reading means 40 is connected to the shutter opening / closing device 2.

  When the shutter control information is read from the nonvolatile memory 12 by the reading means 40 such as a personal computer or PAD, the control mode of the shutter opening / closing device 2 is normally operated by operating the switch 33 of the I / F unit 30. The mode (that is, the operation mode for operating the shutter) may be switched to the control information reading mode.

  Further, a switching means 22 such as a push button switch may be provided in the shutter opening / closing device 2 for mode switching, and the mode may be switched as described above by switching the control information when reading the control information.

  Note that a switch for resetting the shutter control information stored in the nonvolatile memory 12 may be provided in the switchgear 2. However, if the control information is easily deleted, the control information can be used for maintenance. In such a case, the stored contents can be reset only when the switch is set to the reset position and the password is operated in the predetermined order with the push button switch 10 for operation. You can do it.

  The content read from the non-volatile memory 12 by a personal computer or PAD is displayed on the screen, and if a printer is available, it can be printed on paper. For example, if the shutter control information is history information about the occurrence of shutter abnormality and information indicating what kind of abnormality has occurred in the opening operation or closing operation, it can be read at the time of maintenance service, etc. It is very useful, it is easy to reproduce the abnormal behavior of the problem, and it is useful for investigation of the cause and prevention of recurrence. In addition, since the usage status (opening / closing frequency) of the shutter 1 by the user is known, the degree of wear of the shutter 1 can be clearly grasped, and if there is a consumable part, the user can be charged for the replacement cost appropriately.

Next, operations of the shutter opening / closing device 2 and the reading device 20 will be described.
(1) Normal operation of the opening / closing device 2 When the push button switch 10 is operated, an operation signal is input to the CPU 8, and the CPU 8 drives the motor 3 to open and close the shutter 1. At that time, the CPU 8 writes the number of times of opening and closing the shutter 1 in the nonvolatile memory 12.

  When any abnormality relating to the opening / closing of the shutter 1 occurs, the CPU 8 writes the contents of the abnormality that occurred and the number of times of opening / closing at that time in the nonvolatile memory 12.

  For example, when the motor 3 is overheated by continuous operation, the CPU 8 causes the motor 3 to stop urgently by a signal input from the thermal protector. At that time, the CPU 8 records the contents of the thermal abnormality occurrence in the nonvolatile memory 12. When an obstacle is caught in the shutter 1, the CPU 8 urgently reverses or stops the motor 3 by inputting a signal from the obstacle sensing means 14, and at that time the obstacle abnormality occurrence content is recorded in the nonvolatile memory 12. .

(2) Operation of Reading Device 20 of Nonvolatile Memory 12 Here, an operation of reading abnormality history data as the shutter control information stored in the nonvolatile memory 12 by the reading device 20 will be described.
During maintenance of the shutter 1, the reading device 20 is connected to the HA terminal 17 that is normally used as a connection terminal of the HA system, and the CPU 8 outputs the recorded contents of the nonvolatile memory 12 to the reading device 20. In order to start the reading operation in this example, the switching means 22 of the shutter opening / closing device 2 is operated to set the shutter side to the shutter control information reading mode, and the I / F unit connected to the shutter opening / closing device 2 There is a method of setting the shutter side to the shutter control information reading mode by operating the switch 33.
Next, information communication procedures and the like in these two reading methods will be described with reference to FIGS.

A) When using the switching means of the shutter opening / closing device (see FIG. 6 etc.)
In step 11 (hereinafter referred to as S11), the shutter opening / closing device 2 is in the normal operation mode, and the shutter 1 can be operated by a signal from the push button switch 10 or the HA system 18.

  In S12, the switching means 22 in the switchgear 2 is operated. When the switching unit 22 is turned on, in S13, the switchgear 2 enters a monitor mode that is a control information output mode. That is, the CPU 8 stops the motor 3, invalidates the push button switch 10, sets the abnormality history data in the output buffer, and outputs the abnormality history data as a history information signal.

  In S14, the I / F unit 30 receives the history information signal from the switchgear 2, and outputs the history information signal to the reading unit 40 (such as a personal computer).

  In this example, the history information signal input to the I / F unit 30 is a series of 1.5-second history data repeatedly input at 1-second intervals, as shown in FIG. FIG. 9 is a diagram showing the contents of a series of history data. This history data has a 1-bit conduction time of 3.3 msec, and is composed of 1-byte data 1 to 37 in units of 1-byte data having a 1-bit start bit and a 2-bit stop bit. Data 1 and 2 constitute a head, and data 3 to 37 indicate the total number of times of opening and closing of the shutter 1, an abnormality occurrence history (for the past 10 times), and the number of times of opening and closing at the time of occurrence of an abnormality (for the past 10 times).

  In S15, the control information acquisition button 41 of the reading unit 40 (such as a personal computer) is pressed. If not pressed (NO in S15), the control procedure returns to S12. If pressed (YES in S15), the reading unit 40 (such as a personal computer) receives the history information signal twice in S16. The reading unit 40 compares the history information signals received twice in S17, and if they match (YES in S17), the history content is displayed on the screen of the reading unit 40 (personal computer, etc.) in S18. If not (NO in S17), an error is displayed on the screen of the reading unit 40 (such as a personal computer) in S19.

FIG. 8 (4) shows a monitor signal sent from the switchgear 2 to the HA system. Since the shutter 1 is opened and closed under the control of the CPU 8, the open state of the shutter 1 at that time is indicated by H (ON) and the closed state is indicated by L (OFF) continuation signals.

B) When operating the switch 33 of the I / F unit connected to the shutter opening / closing device 2 (see FIG. 7)
In step 21, the shutter opening / closing device 2 is in the normal operation mode, and the shutter 1 can be operated by a signal from the push button switch 10 or the HA system 18.

  In S22, the switch 33 of the I / F unit 30 is operated. When the switching means 22 is turned on (ON in S22), the I / F unit 30 outputs a request signal to the switchgear 2 in S23. The CPU 8 identifies and determines whether the signal input in S24 is a request signal from the I / F unit 30 or a signal from the HA system 18. That is, the request signal is a signal in which the H state continues for one second or more as shown in (1) of FIG. 8, and the HA-related signal from the HA system 18 is in the H state as shown in FIG. 8 (3). Since the duration is 200-300 msec, both signals are distinguishable.

  If it is determined that it is a request signal, in S25, the CPU 8 stops the motor 3, invalidates the push button switch 10, sets the abnormality history data in the output buffer, and outputs the abnormality history data as a history information signal. .

  In S26, the I / F unit 30 receives the history information signal from the switchgear 2, and outputs the history information signal to the reading unit 40 (such as a personal computer).

  The history information signal input to the I / F unit 30 in this example is the same as that shown in the flowchart of FIG. 6, as shown in FIGS.

  As shown in S27, the CPU 8 determines whether or not the request signal from the I / F unit 30 is continuing. If the request signal is continuing (YES in S27), the operator reads the reading unit 40 as shown in S28. If the control information acquisition button 41 of (such as a personal computer) is pressed, the reading unit 40 (such as a personal computer) receives the history information signal twice in S30. When the request signal is not continuing (NO in S27), the CPU 8 enables the push button switch 10 as shown in S29, and the switchgear 2 returns to the normal operation mode as shown in S21.

  The reading unit 40 compares the history information signals received twice in S31, and if they match (YES in S31), the history content is displayed on the screen of the reading unit 40 (such as a personal computer) in S32, and these match. If not (NO in S31), an error is displayed on the screen of the reading unit 40 (such as a personal computer) in S33.

  In either method of FIG. 7 or FIG. 8, if the abnormality history information of the nonvolatile memory 12 read from the reading device 20 is displayed on the display means of the reading device 20 or printed by the printing means, maintenance work is performed.
