Description

  The present invention relates to an automatic door control system, and in particular, an automatic door control capable of setting an opening / closing speed and an opening width without preparing a dedicated wiring by using a setting machine called a handy terminal or a teaching pendant. About the system.

  In general, when a person or an object approaches a door, an automatic door control device inputs a signal from a sensor to the control device. The opening / closing operation is controlled. Various setting values, which are parameters (for example, opening / closing speed, opening width, etc.) used in the door opening / closing control, are set by various setting volumes provided in the control device. In this case, the control device is generally attached to an invisible or ceiling above the door.

  The automatic door control device has a plurality of devices constituting the automatic door, for example, a door controller that controls the speed of the automatic door, a sensor for detecting a passerby, and the like. This automatic door control device sets the opening / closing speed and opening width of the automatic door according to the environment in which the automatic door is installed and the desire of the construction owner to install the automatic door. There is a need to.

  In an automatic door control system, settings such as opening / closing speed and opening width are generally performed by a controller of an automatic door control device. However, the opening / closing speed and the opening width may be reset due to maintenance or the like. In such a case, in addition to the various setting volumes provided in the control device, using a setting device called a handy terminal or teaching pendant, this setting device is connected to the automatic door control device, and the opening / closing speed and opening width are set. Setting work such as is performed.

  When such a handy terminal is connected to the door controller, each parameter currently set in the door controller is transmitted to the handy terminal and displayed on the display unit of the handy terminal. When a parameter to be changed is changed by the input device while viewing this display, the changed parameter is transmitted to the door controller and stored in the door controller.

When using this handy terminal or setting machine called teaching pendant, prepare a dedicated wiring to connect to the automatic door control device, and use this wiring to connect the setting machine to the automatic door control device. Setting work such as opening / closing speed and opening width is performed.

A breakerway switch 50 is connected to the general-purpose input terminal 4a, the serial input terminal 4b, and the serial output terminal 4c via a signal line 51.
The breaker way switch 50 is a switch that does not turn off the power switch 25 of the automatic door device 1 but turns the power switch 25 of the automatic door device 1 off. Therefore, when the breakaway switch 50 is turned on, the power switch 25 of the automatic door device 1 is turned off, that is, the door 2 is opened.

A command from the breaker way switch 50 to the automatic door control device is input as a no-voltage contact signal.
In the automatic door device 1, in order to prevent malfunction due to external noise or switch chattering, a filter circuit is provided by an electric circuit, and a signal input from the general-purpose input terminal 4a is read a plurality of times, and all the levels read are matched. In this case, a technique called a software filter is used, which is regarded as an effective signal. The time constant of the filter circuit is set much shorter than the time constant of the software filter. Accordingly, since the validity of the signal is determined by the time constant of the software filter, even if the signal level is changed below this time constant, the automatic door device 1 ignores it.

In FIG. 2, the serial signal transmitter / receiver 40 is connected to the signal line 51 from the breakaway switch 50 in parallel or in series (daisy chain connection, the same applies hereinafter).
The serial signal transceiver 40 is provided with a serial output terminal 41 and a serial input terminal 42.

Will be connected to.
Since the signal to the general-purpose input terminal 4a is subjected to software filtering to prevent malfunction due to external noise or switch chattering, it is ignored as invalid data if the signal level is intentionally changed within this time constant. Is done.
Therefore, the door controller (microcomputer) 4 receives serial data output from the serial signal transmitter / receiver 40 or serial data output from the door controller (microcomputer) 4 is serialized except for the processing time for recognizing it as invalid data. Transmission to the signal transceiver 40 does not affect the reading and determination of the command.

On the other hand, in the serial input / output terminals 4b and 4c of the door controller (microcomputer) 4, when predetermined serial data is input a plurality of times, it recognizes that serial data has been received and responds.
Data read from the general-purpose input terminal 4a is ignored, and serial data can be received from the serial signal transmitter / receiver 40 without causing malfunction.
The signal line 40a of the serial signal transmitter / receiver 40 is connected to the serial output terminal 4c of the door controller (microcomputer) 4. When serial data is output from the serial output terminal 4c, reading from the general-purpose input terminal 4a is performed. The data is ignored and serial data can be received from the serial signal transmitter / receiver 40 without causing malfunction.
With this configuration, when waiting for a command when the signal from the breaker switch 50 is OFF, signals can be exchanged between the serial signal transmitter / receiver 40 and the door controller (microcomputer) 4 of the automatic door device 1. Become.
