Description

The present invention relates to an opening / closing control system for a building shutter installed in an opening of a building such as a house or a building.

[Problems to be Solved by Prior Art and Invention] Generally, in this type of architectural shutter, the operation control of the switch is performed based on a control command from a control unit configured by using a microcomputer. There is one that I made. By the way, the building shutter has various lifting control conditions depending on the construction site. For example, as a countermeasure when an obstacle is detected during the descent operation of the shutter curtain, it is common to make an emergency stop of the descent of the shutter curtain, but after that, fully open the shutter curtain or only at a predetermined height. To raise or
Alternatively, there is actually a selection such as whether to keep the stopped state as it is. In the past, however, a control unit was created for each of these different elevator control systems, so a large number of control units were required, and maintenance and maintenance of these was not easy and complicated. In that case, the entire control unit must be replaced, which causes trouble in maintenance.

[Means for Solving Problems] In view of the above circumstances, the present invention was devised with the object of providing an opening / closing control system for a building shutter that can eliminate these drawbacks.
The control unit that outputs the control commands necessary to operate the switch is set to the one in which the basic program group that performs the basic processing such as the processing when the power is turned on and the input / output is stored in the memory. Is a program reading unit in which a program memory unit in which a specific control program for operating a switch is stored is set, and a switch based on program data read from the program reading unit based on the stored basic program. And a control command unit that outputs a control command for operating the device.

Further, according to the present invention, even with one type of control unit, a large number of types of control methods can be supported by this configuration.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawing, reference numeral 1 denotes a shutter curtain, which is wound around an internal winding drum 3 in a shutter case 2 provided above an opening, and a switch 4 is driven in a reverse direction. It is the same as in the conventional art that the lifting and opening / closing operations are performed by being guided by the guide rails 5 by the winding operation and the rewinding operation.

Reference numeral 6 denotes a power supply circuit control unit for supplying power to the switch 4, and the power supply circuit control unit 6 includes a control unit 7 described later.
It is set so that the actuator required for switching control of a relay switch or the like is switched in response to a control command from the switch, whereby the necessary drive control of the switch 4 is performed.

The control unit 7 includes a microprocessor unit (CPU), a memory unit (RAM, ROM), an input / output interface unit, and the like. The control unit 7 includes an obstacle detection sensor (for example, There is a seat plate switch and a photoelectric sensor) 8. Opening, stopping, and closing push button switches PBU, PBS, PBD, etc. are adapted to receive signals from switch sensors, but further control section. A program reading unit 9 is connected to 7. The program reading unit 9 includes a program memory unit 10 such as a magnetic card or an IC card having a memory function (various types of memory such as SRAM, MROM, OTP, EEPROM, EPROM can be selected and used as needed). Is set. Then, the control unit 7 registers the data stored in the set program memory body 10 read by the program reading unit 9 in the memory unit, and the microprocessor unit switches based on this data. -Determine the input signal from sensors,
The drive control command for the switch 4 is set to be output to the actuator or to the alarm device 13. In other words, the control unit 7 stores in advance a basic program group, which is an operating system that is directly connected to a hardware program that performs basic processing such as processing when the power is turned on and input / output. The software program that controls the device 4 is not stored in the memory. Then, in this state, the control unit 7 is assembled on site.
On the other hand, with respect to the program memory body 10, a specific control program group corresponding to each electric shutter is stored in its memory function.
When the power of the control unit 7 is turned on in the state where the data is set in the program reading unit 9, the control unit 7 stores the data read by the program reading unit 9 based on the basic program and performs the opening / closing control based on the data. It is becoming like this.

In the embodiment of the present invention configured as described above, the control unit 7 has a basic program group stored in memory, and the control program for operating the switch 4 is stored in a program memory unit 10 which is separately set. It is stored in memory. Therefore, when the electric shutter is installed, if the program data stored in the program memory unit 10 is read into the control unit 7 and stored therein, the operation control of the switch 4 can be performed based on the registered program. become.

In the embodiment of the present invention, the switch 4
The drive control of is controlled electronically by using a microprocessor. In that case, the control unit 7 side initially only stores the basic program, and the specific control program is stored in the memory. Not yet, and the control program follows the one input separately, and accordingly, one kind of control unit 7 is prepared, while
As for the program memory body 10, various control programs corresponding to the control method are stored in memory, and the control unit 7 can be activated with the required program memory body 10 selected and set for each site. It would be good. As a result, it is not necessary to prepare various types of control units corresponding to various control methods as in the conventional art, and it is not possible to significantly simplify the maintenance of these control units. It is possible to quickly respond to changes in specifications.

[Advantages] In short, since the present invention is configured as described above, it is necessary to select and set an appropriate one from the separately set program memory bodies for the control unit. As a result, it is possible to directly support a wide variety of switch operation control systems. Therefore, even if the control unit is of one type, if many types of program memory units are set according to the control method, it is possible to perform opening / closing operation control according to the set number. Like the one that dealt with the difference in the control system by increasing the type of the control unit, it is not forgiving that its maintenance will not be troublesome and complicated,
The change in specifications can be handled very easily, and the maintainability can be greatly improved.
