Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic blind system, and more particularly to an electronic blind system capable of promptly grasping a condition such as a failure of the electronic blind.

[0002]

2. Description of the Related Art Blinds are very widely used in windows of buildings for shading and for blocking see-through. In large offices, electronic blind systems that electrically control the raising and lowering of the blinds by using a motor instead of manually are installed. This type of system is referred to as an electronic blind system, in which a motor and a drive control board are installed in a blind, and a plurality of blinds are centrally and collectively controlled from a management center side by connecting with a communication line. In the electronic blind system, each blind is controlled by connecting a personal operation panel for residents, an area collective operation panel, a remote controller, etc. to the blind. In addition, a blind management database, area management database, etc. are prepared for the controller and man-machine device on the control device side that are connected to the blinds via a communication line, and automatic control such as schedule control and solar radiation control is performed. ing.

In such a system, it is important to promptly notify an operating state such as a failure of the electronic blind. As a maintenance tool in the field of electronic blinds, Japanese Utility Model Publication No. 62-144187 discloses a motor for driving a robot, in order to predict the life of the motor, the number of rotations of the motor is detected and integrated, and brush wear is detected by this counting time. By predicting the degree, damage due to motor damage,
A technique for predicting the life of a motor and performing maintenance (replacement) before the motor fails is disclosed.

[0004]

The above-mentioned conventional technique attempts to predict the life of the motor based on the total number of revolutions of the motor, but the life of the motor does not depend only on the number of revolutions. That is, the motor requires high electric power at the time of starting, and the number of times of starting greatly contributes to the life. Further, the motor overheats when it is operated continuously for a long time, which also affects the life of the motor. In particular, in an electronic blind system, statistical data such as the operating time of blinds, the number of times of operations, and the number of times of operations are not only used as a guideline that indicates the life of the motor, but also damage to the lifting tape, wear of various gears, and maintenance of slats (wings). It can be a guide to know the time,
In the conventional electronic blind system, there is no system that uses the statistical data. Therefore,
When a blind failure occurs in the conventional electronic blind system, the failed part is repaired each time, or it is left until the next maintenance period.

Therefore, an object of the present invention is to measure the statistical data such as the number of blind motor revolutions, the number of operations, the operating time, the number of operations, etc., and predict the life of not only the motor but also various parts, so that the failure blind It is an object of the present invention to provide an electronic blind system that can maintain a comfortable state and improve service for residents while executing planned maintenance to reduce maintenance cost.

[0006]

In order to solve the above-mentioned problems, an electronic blind system according to the present invention is an electronic blind system in which a motor drives a driving operation such as raising and lowering of a blind.
Furthermore, the number of times of operation, the time of operation, the collecting means for collecting statistical data including the number of times of operation, the statistical data collected by the collecting means are accumulated in time series, and the electronic blind system of the electronic blind system is based on the accumulated statistical data. And maintenance information generating means for generating maintenance information of the constituent elements.

Here, the collecting means is provided corresponding to each of the plurality of blinds, and is included in an electronic control unit that detects statistical data regarding each blind, and the statistical data from the electronic control unit is collected by a host device.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a system configuration diagram showing an embodiment of an electronic blind system according to the present invention.

The electronic control unit 1 housed and installed in the upper head box of the electronic blind includes a motor 11, a motor statistical data detecting unit 12, and a statistical data counting unit 1.
3, the operation statistical data detection unit 14, the blind communication unit 15 as well as a power supply unit and a CPU arithmetic unit,
The motor 11 controls the elevation of the blind.

The higher-level device 2 includes a man-machine unit 21, a statistical data processing unit 22, a statistical data storage unit 23, and a higher-level device communication unit 24. Through the higher-level device communication unit 24, the electronic control unit 1 (brand Communication unit).

The motor statistical data detection unit 12 detects statistical data about the motor, and its form differs depending on the type of the motor. For example, when the motor continuously operates like a DC motor, the motor is detected by an encoder or the like. When the motor behaves like a pulse motor, it has a function to quantify the operation amount of the, and not the control result of the motor, but the number of pulses output to the motor as a control command to monitor the value. There is.

The operation contents of the personal operation unit 3 adjacent to the electronic blind and operated by the resident are detected by the operation unit statistical data detection unit 14. The information detected by the motor statistical data detecting unit 12 and the operating unit statistical data detecting unit 14 is counted by the statistical data counting unit 13. The statistical data generated by the various detection mechanisms and the statistical data counting unit 13 are, for example, the motor rotation speed, the motor operating time, the motor operating frequency, the operating frequency, and the like. Here, the number of operations is the personal operation unit 3
And the operation controlled by remote control from the host device 2 are separately counted.

Generally, the electronic control unit 1 tends to be unable to store these statistical data for a long time due to reliability of memory power backup and the like, and memory capacity. Therefore, the higher-level device 2 periodically receives the statistical data to the statistical-data storage unit 23 via the higher-level device communication unit 24 and the blind communication unit 15. At this time, since the statistical data storage unit 23 stores the collected statistical data in a time series, the man-machine unit 21 can browse the contents.

The host device 2 automatically monitors the statistical data and predicts the life by a simple upper limit comparison,
It has a statistical data processing unit 22 for predicting the lifespan by various statistical calculation processes and notifying the man-machine unit 21 as an alarm or warning. The statistical data processing unit 22 automatically notifies the alarms and warnings, and at the same time, the man-machine unit 2
When there is a request from 1, it also has a temporary calculation function for statistically processing statistical data and displaying it in a graph or the like.

As described above, in the prior art, only the number of rotations of the motor is used as the life factor, but in the embodiment of the present invention, the operating time, the number of times of operation, the number of times of operation, etc. are also detected, and these are time-series. By accumulating and performing statistical processing, the accurate life can be known, and at the same time, the life of mechanisms other than the motor such as lifting tapes, gears, and slats can be predicted. In particular, the maintenance cost can be reduced by collecting the collected statistical data in the man-machine device which is the higher-level device of the system. Further, since the maintenance time can be grasped, it becomes possible to systematically secure the maintenance cost and the repair parts.

[0016]

As described above, according to the electronic blind system of the present invention, it is possible to remotely predict the maintenance timing of a large number of electronic blinds installed, so that the maintenance can be performed frequently as in the conventional case. There is no need to carry out and repair the blinds that have failed. In addition, since it is not necessary to inspect all the blinds in the building to walk during maintenance, it is possible to maintain a comfortable environment at all times, improve service to residents, and reduce maintenance costs.
Furthermore, since the time required for maintenance can be predicted in advance, maintenance costs and repair parts can be secured systematically and economically.
