It is attached to the door 2 by screwing. A through-hole through which the thumb turn 5 can pass is provided in the approximate center of the base a8. Further, when mounting the base a8 to the door 2, the attachment a6 is performed while adjusting the position and direction of the attachment a6 so that the attachment a6 is covered with the knob 5a of the thumb turn 5. Since the attachment a6 is appropriately designed according to the shape of the thumb 5a of the thumb turn 5, the attachment a6 can be selected and applied to various thumb turns 5. And this motor gear apparatus A is connected to the electronic control apparatus B mentioned later by the connection line L2.

  A light receiving device C is disposed on the door 2 outside the building. The light receiving device C includes a light receiving element c1, a microprocessor c2, a communication driver c3, a plurality of LEDs c4, and the like, and is connected to an electronic control device B described later by a connection line L1. LEDc4 is a plurality of LEDs, such as an LED that lights when unlocked, an LED that lights when locked, or an LED that lights when there is an error in an administrator code or password received from an external control terminal D described later It is comprised from this LED. Thereby, the operation state can be clearly confirmed visually. In addition, when LEDc4 is unnecessary, it does not need to be included in the component of the light-receiving device C. FIG. The light receiving device C may be configured such that only the light receiving element c1 is attached outdoors and the microprocessor c2 and the communication driver c3 are provided indoors.

  B is an electronic control device, which is disposed inside the building, and is connected to the motor gear device A and the light receiving device C described above via communication drivers b1 and b3. A microprocessor b2 is built in the electronic control device B, and the operation of the motor gear device A and the light receiving device C is controlled by the microprocessor b2. The microprocessor b2 stores an administrator code and password for a legitimate accesser in advance, authenticates the administrator code and password input from the external control terminal D described later, and instructs a predetermined operation. is there. A series of operations of the entire system is as described later.

  D is an external control terminal, which is a small portable terminal that is easy to carry. The external control terminal D is provided with a display unit and an input unit, and control software is incorporated in advance. When the door 2 is locked or unlocked, an administrator code and password are input using the input unit, and a signal is transmitted by selecting the locking or unlocking operation toward the light receiving element c1 of the light receiving device C.

As the external control terminal D, a dedicated external control terminal designed exclusively for this system may be used, but a mobile phone capable of infrared transmission / reception, which is widely used, can also be used. When a mobile phone is applied, for example, it is possible to incorporate software by downloading control software uploaded in advance on a predetermined Web, and can be easily tailored to an external control terminal It is. In this way, by applying a mobile phone to the external control terminal, it is not necessary to prepare a new dedicated external control terminal, so that the cost of the entire system can be reduced.

  E is a personal computer. For example, when each building is locked or unlocked from a remote central management control building, a control terminal provided in the central management control building is connected to a local area network (hereinafter referred to as LAN) or the public. The personal computer E is connected via the line L4. The personal computer E and the electronic control unit B are connected by a connection line L3. In place of the PC, a communication driver having a function of appropriately converting a signal between the public line L4 and the connection line L3 may be used. Thus, the cost of the entire system can be further reduced by using the communication driver instead of the PC.

  Next, a series of operations of the entire system will be described. The case where the locked door 2 is unlocked using the mobile phone type external control terminal D is as follows. The administrator carries the external control terminal D and moves to the target building, inputs a predetermined administrator code and password, specifies unlocking, and sends an infrared signal toward the light receiving element c1 of the light receiving device C. Send.

  Then, since the light receiving element c1 converts the received infrared signal into an electrical signal and outputs it, the received signal is input to the microprocessor c2. When the reception signal is input, the microprocessor c2 transmits the reception signal to the microprocessor b2 of the electronic control device B via the communication driver c3, the connection line L1, and the communication driver b1.

  When the received signal is received by the microprocessor b2, the microprocessor b2 confirms the administrator code and password transmitted from the administrator, compares them with the regular administrator code and password stored in advance, and determines the authentication. I do. Here, if the authentication is not authenticated, an authentication error signal is sent to the light receiving device C, and the light receiving device C that has received the authentication error signal is an LED for displaying “authentication error” among the plurality of LEDs c4. Lights up. Further, since the unlocking is not performed at this time, the electronic control unit B does not send an unlocking instruction signal to the motor gear unit A.

  On the other hand, if authenticated, an authentication signal is sent to the light receiving device C, and the light receiving device C that has received the authentication signal turns on an LED for “authentication” display among the plurality of LEDs c4. At this time, in order to perform unlocking, the electronic control unit B sends an unlocking instruction signal to the motor gear unit A.

  When an unlock signal is input from the microprocessor b2 of the electronic control device B to the motor drive circuit a10 of the motor gear device A, the motor drive circuit a10 outputs a motor rotation signal so that the motor a2 rotates in the unlocking direction. Output. Then, the motor a2 rotates in the unlocking direction, and the driving force of the motor a2 is applied to the gear device a3 engaged with the motor a2, the shaft a5 engaged with the gear device a3, and the attachment a6 integrated with the shaft a5. The thumb 5a of the thumb turn 5 that is transmitted and covered by the attachment a6 rotates in the unlocking direction.

  After completing the indoor work, the administrator carries the external control terminal D and moves outdoors, inputs a predetermined administrator code and password, designates locking, and applies to the light receiving element c1 of the light receiving device C. Send an infrared signal.

  Then, since the light receiving element c1 converts the received infrared signal into an electrical signal and outputs it, the received signal is input to the microprocessor c2. When the reception signal is input, the microprocessor c2 transmits the reception signal to the microprocessor b2 of the electronic control device B via the communication driver c3, the connection line L1, and the communication driver b1.

  When the received signal is received by the microprocessor b2, the microprocessor b2 confirms the administrator code and password transmitted from the administrator, compares them with the regular administrator code and password stored in advance, and determines the authentication. I do. Here, if the authentication is not authenticated, an authentication error signal is sent to the light receiving device C, and the light receiving device C that has received the authentication error signal is an LED for displaying “authentication error” among the plurality of LEDs c4. Lights up. Further, since locking is not performed at this time, the electronic control unit B does not send a locking instruction signal to the motor gear device A.

  On the other hand, if authenticated, an authentication signal is sent to the light receiving device C, and the light receiving device C that has received the authentication signal turns on an LED for “authentication” display among the plurality of LEDs c4. At this time, since the locking is performed, the electronic control unit B sends a locking instruction signal to the motor gear unit A at the same time.

  When a locking signal is input from the microprocessor b2 of the electronic control device B to the motor drive circuit a10 of the motor gear device A, the motor drive circuit a10 outputs a motor rotation signal so that the motor a2 rotates in the locking direction. . Then, the motor a2 rotates in the locking direction, and the driving force of the motor a2 is transmitted to the gear device a3 engaged with the motor a2, the shaft a5 engaged with the gear device a3, and the attachment a6 integrated with the shaft a5. Then, the knob 5a of the thumb turn 5 covered on the attachment a6 rotates in the locking direction. Thereby, the lock fitting 4 is moved from the inside of the door 2 toward the hole formed in the wall 1 and the door 2 is locked.

  Even at the time of locking, the contact output signal of the switch a9 is input to the microprocessor b2 of the electronic control device B, and the electronic control device B can recognize the locked state of the thumb turn 5. If the signal from the switch a9 indicates the unlocked state even though the electronic control device B has output the locking command, an error signal such as “motor gear device error” is output to the light receiving device C. By turning on the LEDc4, an alarm can be displayed to an administrator who is trying to lock the door 2.

  When the door 2 is locked from a remote centralized control building regardless of the external control terminal D, an administrator code and password are entered into the control terminal installed in the centralized control building and a lock command is issued. Is output. Then, a locking command is transmitted to the personal computer E via the LAN or the public line L4, the personal computer E outputs a locking command to the electronic control device B, and the door 2 is locked.
