Description

Automatic door control method and automatic door controller {METHOD OF CONTROLLING AUTOMATIC DOOR AND CONTROLLER FOR AUTOMATIC DOOR}

The present invention relates to an automatic door control method and an automatic door controller, and more particularly, to an automatic door control method having an automatic correction function capable of correcting whether or not a preset function corresponding to a sensor is stopped according to a state change of a sensor checking signal. It is about door controller.

In general, automatic doors have been widely installed as conveniences that can be opened and closed automatically by power when people enter and exit. Automatic doors are mainly installed and operated at the entrances of apartments, hotels, buildings, etc., where people frequently access them. Recently, the automatic doors have been spread to general buildings such as restaurants and supermarkets as well as large buildings.

Such automatic doors may be configured to be opened and closed in various opening and closing manners depending on the installation location and use. For example, the opening and closing method of the automatic door may be divided into an opening and closing method by a sensor for detecting a person or an object, an opening and closing method by a remote control operation, an opening and closing method by a button operation, or an opening and closing combination thereof.

Such automatic doors have just begun to be used for automatic opening and closing of doors, but in recent years, as the user's interest in the access control function and convenient use as well as the simple function of opening and closing automatic doors increases, the automatic doors can be used more conveniently and variously. It is being developed to have various additional functions.

On the other hand, the general automatic door system is equipped with various types of sensors, such as a sensor for detecting various conditions and operations necessary for opening and closing the automatic door and a sensor for detecting the presence of various abnormalities, each sensor in real time (or a certain minute time unit) The predetermined function of the automatic door corresponding to the sensor may be stopped according to whether the checked and checked sensor checking signal is normal.

However, in the related art, when a sensor checking signal is detected as abnormal, a predetermined function is simply stopped according to a predetermined sequence, which is not only troublesome and inconvenient to use, but also very difficult to maintain. That is, conventionally, regardless of whether the abnormal sensor checking signal is temporarily detected or continuously detected, once the sensor checking signal is detected as abnormal, the corresponding function is simply configured to stop, and after a predetermined time, the sensor checking signal is normally It is configured to maintain the stopped state of the corresponding function even when it returns. Therefore, in the related art, even when a certain function is temporarily stopped due to a temporary abnormal checking signal, there is a troublesome and inconvenient problem of restoring the stopped function by separate operation and management of an administrator.

For example, in the case of a sensor exposed to the outside in a conventional automatic door system, rainwater flows into the contact point of the sensor due to rainy weather or other reasons (temporary external force, etc.), and a temporary disconnection may occur. The sensor checking signal is detected abnormally and the function corresponding to the sensor may be stopped. However, in the related art, even if an abnormal checking signal due to a temporary disconnection returns to a normal state after a predetermined time, a stop state of a predetermined function is maintained. Therefore, in order to restore the stopped function to a normal state, a separate operation and management of an administrator must be performed. There is a troublesome and uncomfortable problem.

In addition, conventionally, each sensor constituting the automatic door system is configured to be connected in a series connection method along one line, so when any one of the sensors is disabled, it is impossible to check other remaining sensors that are connected in series and operate normally. There is a problem that is recognized as, and there is a problem that the reliability and stability deteriorated accordingly.

The present invention provides an automatic door control method and an automatic door controller that can provide convenience in use and management. In particular, the present invention provides an automatic door control method and an automatic door controller capable of correcting whether a corresponding preset function is stopped according to a change in state of a sensor checking signal.

According to a preferred embodiment of the present invention for achieving the above object of the present invention, the automatic door control method comprises the steps of providing a sensor and a control unit for controlling a preset function of the automatic door corresponding to the sensor, by checking the sensor Determining whether the checking signal of the sensor is normal or abnormal, stopping the preset function corresponding to the sensor if the checking signal of the sensor is abnormal, and checking the sensor signal to the normal state when the preset function is stopped. Determining whether the switch has been switched, and restoring the preset function stopped when the checking signal of the sensor is changed to normal.

In the present invention, the sensor may include both a sensor for detecting various states and operations required for opening and closing an automatic door and a sensor for detecting various abnormalities, as well as various safety sensors for promoting safety. Each of the plurality of sensors may be connected in parallel to the control unit in a multi-port manner so as to independently check each other, and even if a preset function by any one of the plurality of sensors is stopped, the other sensors may be determined to be normal. The preset function can be maintained. In some cases, each sensor can be connected in series.

In addition, in the present invention, the preset function means a preset function corresponding to each sensor. For example, the preset function corresponding to the infrared sensor for detecting the entrance and exit of the person can be understood as the opening and closing of the automatic door according to the infrared detection of the person, in addition to the preset function corresponding to the brake sensor of the automatic door is the speed and operation of the automatic door. It can be understood as the braking of the automatic door according to the distance detection.

In addition, in the present invention, the sensor checking signal may mean a signal indicating whether the sensor operates normally or abnormally as a result of detecting the abnormality of the sensor. The abnormal sensor checking signal may include, for example, a signal that is detected when a corresponding sensor does not perform its role due to disconnection, breakage, or external pressure.

The controller may determine whether the checking signal of the sensor is normal or abnormal on a micro time basis or in real time, and the checking of the sensor may be maintained even when the preset function is stopped. In some cases, when the preset function corresponding to the sensor is stopped, the checking of the sensor may be stopped for a predetermined time.

The method of stopping the preset function of the automatic door according to the abnormal sensor checking signal may be changed in various ways according to the required conditions and the installation environment. For example, the preset function may be configured to stop immediately when an abnormal sensor checking signal is detected. In some cases, the preset function may be set when the abnormal checking signal generation time of the sensor elapses more than the preset setting time. It can be configured to stop.

According to another preferred embodiment of the present invention, the automatic door controller is provided to control the preset function of the sensor and the automatic door corresponding to the sensor, and stops the preset function if it is determined that the checking signal of the sensor is abnormal, And a control unit for restoring the stopped preset function when the checking signal of the sensor is changed to the normal state while the setting function is stopped.

Also, a memory unit may store a setting value for a time for generating an abnormal checking signal of the sensor, and the controller may stop a corresponding preset function when the time for generating an abnormal checking signal of the sensor elapses above the setting value.

For reference, in the present invention, the automatic door may include a sliding door, a sliding door, a revolving door, and the present invention is not limited or limited according to the opening / closing method of the automatic door. .

According to the automatic door control method and the automatic door controller according to the present invention, it is possible to provide convenience in use and management by allowing the corresponding preset function to be stopped or not according to the state change of the sensor checking signal.

In particular, according to the present invention, when the sensor checking signal in the abnormal state is changed to the normal state after a predetermined time elapses due to a temporary disconnection, the corresponding preset function may be restored to the normal state without a separate operation of the administrator. As described above, according to the present invention, the occurrence of abnormal checking signal (temporary abnormal checking signal or continuous abnormal checking signal generation) without the hassle of having to perform separate operation and management of the administrator every stop of the preset function corresponding to each sensor. ), Whether or not the preset function is stopped may be corrected.

In addition, according to the present invention by connecting a plurality of sensors for performing various sensing operations required for the opening and closing of the automatic door in parallel to the controller to check independently of each other in a multi-port method, any one of the sensors is disabled Inability to check the remaining sensors can be prevented, improving reliability and stability.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, but the present invention is not limited or limited by the embodiments. In describing the present invention, a detailed description of known functions or configurations may be omitted to clarify the gist of the present invention.

1 is a block diagram illustrating a structure of an automatic door system to which an automatic door controller according to the present invention is applied, and FIG. 2 is a view illustrating a configuration of an automatic door controller according to the present invention.

As shown in Figures 1 and 2, respectively, the automatic door controller 300 according to an embodiment of the present invention can be applied to a conventional automatic door system (10).

Hereinafter, the door (10, 20) that the automatic door system 10 is provided to selectively open and close the entrance, the drive unit 100 for providing a driving force for moving the door (10, 20), the drive unit 100 For example, a power transmission unit 200 for transmitting the driving force to the doors 10 and 20, and an automatic door controller 300 for controlling the opening and closing of the doors 10 and 20 will be described. .

The structure and opening / closing manner of the doors 10 and 20 may be variously changed according to required conditions and installation environments. For example, two doors 10 and 20 may be provided so that one end thereof faces each other, and each door 10 and 20 may be configured to slide left and right and to open and close the door in cooperation with each other. In some cases, only one door may be configured to open and close the door. Alternatively, the door may be configured to be opened or closed by three or more doors.

As the driving unit 100, a conventional driving motor may be used, and the structure and method of the power transmission unit 200 may be variously changed according to required conditions. For example, the power transmission unit 200 is provided at both ends of the timing belt 210 and the timing belt 210 so as to be rotatable, respectively, and at least one pair of gear pulleys 220 and 230 defining a movement trajectory of the timing belt 210. It may be configured to include). At least one of the gear pulleys 220 and 230 may be connected to the driving motor, and the timing belt 210 may be rotated clockwise or counterclockwise by the driving force of the driving motor.

The first door 10 may be connected to the upper portion of the timing belt 210 through the first bracket 240, and the second door 20 may be connected to the lower portion of the timing belt 210 through the second bracket 250. Can be connected. Therefore, as the timing belt 210 circulates, the first bracket 240 and the second bracket 250 can be moved in a direction in which they are simultaneously approached or spaced apart from each other. As a result, the first door 10 and the second bracket 250 are moved. The door 20 can be moved and opened at the same time.

On the other hand, the automatic door controller 300 for controlling the opening and closing of the door (10, 20) is electrically connected to the drive unit 100, it is possible to adjust the operation of the drive unit 100 and its operating conditions.

In addition, the controller 300 is configured to include various types of sensors 310, such as a sensor for detecting various conditions and operations required for opening and closing the automatic door and a sensor for detecting the presence or absence of various abnormalities, each sensor 310 Is configured in such a manner that the operation of the corresponding preset function can be controlled according to whether the checked sensor checking signal is normal or abnormal in real time (or a predetermined minute time unit). For example, the automatic door system may include an infrared sensor, an open button, a remote control sensor or a weight sensor, and may be configured to open each door in response to detecting one or more of the sensors. If the checking signal of the sensor is abnormally detected, the opening / closing function of the door by the remote control sensor may be stopped.

As described above, the preset function means a preset function corresponding to each sensor 310. For example, the preset function corresponding to the infrared sensor for detecting the entrance and exit of the person can be understood as the opening and closing of the automatic door according to the infrared detection of the person, in addition to the preset function corresponding to the brake sensor of the automatic door is the speed and operation of the automatic door. It can be understood as the braking of the automatic door according to the distance detection.

In the present invention, the sensor checking signal refers to a signal indicating whether the sensor 310 operates normally or abnormally as a result of detecting an abnormality of the sensor. In addition, the abnormal sensor checking signal may include, for example, a signal detected when the corresponding sensor 310 does not perform its role due to disconnection or damage.

In addition, the plurality of sensors 310 for performing the various sensing operations required for opening and closing the automatic door as described above is preferably connected in parallel to the control unit to check independently of each other in a multi-port (multi-port) method. Such a structure makes it possible to prevent the checking of the remaining sensors as one of the sensors 310 is disabled.

In addition, the controller 300 is configured to correct whether or not to stop the corresponding preset function according to the state change of the sensor checking signal. That is, the controller 300 may correct whether the corresponding preset function is stopped according to the temporary abnormal sensor checking signal or the continuous abnormal sensor checking signal. For example, the controller 300 is a sensor check signal that is abnormal in the abnormal state due to a temporary disconnection caused by rain or the like introduced into the contact of the sensor due to rain or other reasons (temporary external force, etc.) after a predetermined time elapses. In case of transition to the state, the preset function which has been stopped without the administrator's separate operation can be restored normally. To this end, the controller 300 is provided to control the preset function of the automatic door corresponding to the sensor 310 together with the sensor 310 described above. When the checking signal is determined to be abnormal, the controller 300 stops the preset function and the automatic inquiry When the checking signal of the sensor 310 is changed to normal in the stopped state, the control unit 320 is configured to restore the stopped preset function to normal.

The controller 320 may be configured to include a conventional microcomputer, and as described above, whether or not the corresponding preset function is stopped is corrected according to the state change of the sensor checking signal (normal switching of the abnormal sensor checking signal). To be able.

The controller 320 may be configured to stop a corresponding preset function immediately when an abnormal sensor checking signal is detected. In some cases, the abnormal sensor checking signal may be continuously performed for a predetermined time (for example, 3 seconds). It may be configured to stop the preset function when detected. To this end, the controller 300 may include a memory unit 330 in which a setting value for an abnormal checking signal generation time of the sensor 310 is stored, and the controller 320 generates an abnormal checking signal of the sensor 310. When the time elapses beyond the preset value set in the memory unit 330, the preset function may be stopped.

As described above, the memory unit 330 may store in advance a setting value for an abnormal checking signal generation time of the sensor 310 according to a required condition and an installation environment. Various programs for controlling the operation conditions of the door and the operation of the automatic door system as a whole may be stored.

With this configuration, if an abnormal sensor checking signal is detected due to a temporary disconnection, the corresponding preset function may be stopped.However, if the sensor checking signal in an abnormal state is changed to a normal state after a predetermined time has elapsed, the administrator does not need to operate it. The preset function which was stopped can be restored to normal again.

Hereinafter, an automatic door control method according to the present invention will be described. 3 is a block diagram illustrating an automatic door control method according to the present invention. In addition, components and descriptions that may be understood as the same concept may be omitted without repetition, and the same reference numbers may be described with reference to other drawings without specific reference.

As shown in FIG. 3, the automatic door control method according to the present invention includes providing a sensor 310 and a control unit 320 for controlling a preset function of the automatic door corresponding to the sensor 310, the sensor 310. (S10) to determine whether the checking signal of the sensor 310 is normal or abnormal, and if it is determined that the checking signal of the sensor 310 is abnormal, stopping the preset function corresponding to the sensor 310. Step S30, determining whether the checking signal of the sensor 310 has been switched to the normal state in the state in which the preset function is stopped (S40); Restoring the function (S50). In addition, the sensors 310 may be connected to the controllers in parallel in a multi-port manner and may be independently checked.

First, each sensor 310 performing various sensing operations required for automatic door opening and closing is checked in real time to determine whether the checking signal of the sensor 310 is normal or abnormal. (S10) For example, this step (S10). In the rainy weather or other reasons (temporary external force, etc.) when rainwater is introduced into the contact point of the sensor, if the disconnection phenomenon occurs, the check signal of the corresponding sensor may be determined to be abnormal. In this step S10, the controller 320 may determine whether the checking signal of the sensor 310 is normal or abnormal in units of micro time.

Next, if it is determined that the checking signal of the sensor is abnormal, the corresponding preset function is stopped. (S30) For example, if the checking signal of the infrared sensor is detected abnormally in this step (S30), opening and closing of the door by the infrared sensor. The function may be stopped, and if the checking signal of the remote controller sensor is abnormally detected in the same manner, the opening / closing function of the door by the remote controller sensor may be stopped. In addition, even if the preset function by any one of the various types of sensors is stopped in this step (S30), the preset function by another sensor determined to be normal can be maintained as normal.

The preset function stopping method according to the abnormal sensor checking signal may be variously changed according to a required condition and an installation environment. For example, the preset function may be configured to stop immediately when an abnormal sensor checking signal is detected. In some cases, an abnormal checking signal generation time of the sensor 310 may be greater than or equal to a preset value set in the memory unit 330. When the elapsed time, the corresponding preset function may be stopped. (S20)

Next, it is determined whether the checking signal of the sensor 310 is changed to normal while the automatic door is stopped. (S40) The checking of the sensor 310 continues in real time even when the corresponding preset function is stopped. (Or a fixed minute time unit), and in this step (S40) it is determined whether the sensor checking signal that was abnormal has been converted to normal. As an example, in the case of a temporary disconnection due to the inflow of rainwater, it may be switched back to a normal state after a predetermined time, and this may be determined as a normal switching of the check signal of the sensor 310.

Thereafter, if it is determined that the checking signal of the sensor 310 has been changed to normal, the preset function that has been stopped is normally restored again (S50).

As described above, the present invention has been described with reference to the preferred embodiments, but those skilled in the art can variously modify the present invention without departing from the spirit and scope of the invention as set forth in the claims below. It will be appreciated that it can be changed.
