Abstract

<P>PROBLEM TO BE SOLVED: To provide an automatic door device for crime prevention reduced in the number of parts and cost and improved in working efficiency. <P>SOLUTION: When an operation stop switch is turned on, the operating state of the device is apparently stopped, but the supply of power to a door controller and a magnetic pole position sensor is maintained. In the processings of steps S36-S37, the device determines whether a break and enter occurs or not. When an electric lock is locked, the occurrence of pulse signal is considered to be absent. However, if the pulse signal of predetermined quantity is counted in a control and calculation part, a break and enter is considered to occur. In steps S36-S37, a warning signal generation determination means is operated. In the processing of step S38, since a break and enter is considered to occur, a processing for generating a warning signal and outputting it to a device to be transmitted is performed. In step S38, the warning signal generation determination means and a warning signal output means are operated. <P>COPYRIGHT: (C)2009,JPO&INPIT

In addition, the control calculation unit 45 includes an operation stop unit 50, a lock / unlock unit 51, and an alarm signal generation determination unit 52 that are the gist of the present invention.

  The door stroke length measuring means 30, the fully open position detecting means 31, the fully closed position detecting means 32, and the door position detecting means 33 have the same functions as in the prior art. For example, the door stroke length measuring means 30 drives the motor 5 after the power switch 25 is turned on to drive the door 2 at a low speed, and synthesizes the position / velocity pulse signal from the magnetic pole position sensor 7 of the motor 5 and determines the rotation direction. It has a function of counting through the circuit 19 and storing the counted value in the storage unit 20 as a reference door stroke value.

The high-speed operation, the deceleration operation, and the low-speed operation are executed.

  The operation stop means 50 is configured to operate based on the ON / OFF operation of the operation stop switch 43. More specifically, the operation stopping means 50 supplies power to the motor 5 by operating the power shut-off unit 48 while maintaining power supply to the door controller 42 and the magnetic pole position sensor 7 by turning on the operation stop switch 43. Shut off (or stop the output of the door open / close signal to the motor 5), stop the device operation state apparently, and the device state that is apparently stopped by the operation of the operation stop switch 43 from ON to OFF It is configured to cancel.

  Further, when the operation stop switch 43 is turned ON, the operation stop means 50 stops transmitting a lighting signal of a pilot lamp (not shown) or operates the power shut-off unit 48 to operate the internal sensor 21, the external sensor 22, or the safety The power supply to the light switch 23 is cut off, or the input reception from the internal sensor 21, the external sensor 22, and the safety light switch 23 is stopped.

  Further, when the operation stop switch 43 is operated from ON to OFF, the operation stop means 50 starts transmitting a pilot lamp lighting signal (not shown) or operates the power shut-off unit 48 to activate the internal sensor 21 or the external The power supply to the sensor 22 and the safety light switch 23 is resumed, and the input reception from the internal sensor 21, the external sensor 22, and the safety light switch 23 is started.

  Furthermore, the operation stopping means 50 is operated to turn on the operation stop switch 43. When the door 2 is in an automatic opening / closing operation at this time, the motor 5 is braked via the motor drive / speed control unit 17 to 2 is completely stopped.

  Furthermore, when the door 2 is manually opened and closed during the operation state of the apparatus that is apparently stopped, the operation stopping means 50 moves the door 2 according to the moving direction of the door 2 and the position of the door 2. It is configured to suppress the momentum.

  The locking / unlocking means 51 is a lock for operating the electric lock 34 when the door 2 is manually opened and closed and the door 2 is in the fully closed position when the apparatus is in an apparently stopped state. It is configured to accept a signal generated by an ON / OFF operation of the switch 44.

  The alarm signal generation determination means 52 is a pulse signal output for position detection during the opening / closing operation of the door 2, that is, a pulse signal from the magnetic pole position sensor 7 and the electric lock 34 controlled by the locking / unlocking means 51. Depending on the control state, it is configured to determine whether or not it is necessary to generate an alarm signal necessary for security measures. The alarm signal generation determination unit 52 generates an alarm signal when it is determined that the alarm signal needs to be generated, and outputs the alarm signal to a device or device (transmission target device) associated with the automatic door device 41 via the alarm signal output unit 53. It is configured to (send).

  In this embodiment, the transmission target devices that are the output destinations of the alarm signal from the alarm signal generation determination means 52 are a security camera recorder 55 with a liquid crystal monitor connected to the security camera 54 and a security light 56 with an alarm device. (See FIG. 1 and FIG. 2, which is an example). Upon receiving the warning signal, the transmission target device threatens the intruder with, for example, an alarm sound and strong light emission, and can activate the crime prevention camera 54 for identifying the illegal intruder to perform shooting recording. It has become.

  Next, referring to the configuration diagram of FIG. 1 and the flowcharts of FIGS. 3 to 6, the control calculation unit 45, the operation stop unit 50, the lock / unlock unit 51, the control of the alarm signal generation determination unit 52, etc. Will be described.

  1 and 3, when the door stroke length measuring unit 30 executes the door stroke length measuring process (step S1), the control calculation unit 45 proceeds to the process of step S2. In the process of step S2, it is determined whether or not the operation stop switch 43 has been turned ON. When the operation stop switch 43 is not turned on (NO in step S2), after performing the normal opening / closing process of step S3 (the process is the same as the conventional process for the door 2 and will not be described here), the process proceeds to step S2. Return to the process and repeat this process again. On the other hand, when the operation stop switch 43 is turned on (YES in step S2), the operation stop process in step S4 is executed. In the operation stop process of step S4, the operation stop means 50 operates. After executing the operation stop process of step S4, the process returns to the process of step S2 and this process is repeated again.

  In FIG. 1 and FIG. 4, when the operation stop process is started, the process of step S11 is first executed. In the process of step S11, the transmission of a pilot lamp lighting signal (not shown) is stopped, the power cutoff unit 48 is operated to cut off the power supply to the internal sensor 21, the external sensor 22, and the safety light switch 23, or the internal The input reception from the sensor 21, the external sensor 22, or the safety light switch 23 is stopped. After performing the process of step S11, it transfers to the process of step S12.

  In the process of step S12, it is determined whether or not the magnetic pole position sensor 7 is generating a pulse signal, in other words, whether or not the door 2 is in an automatic opening / closing operation. If the magnetic pole position sensor 7 is generating a pulse signal (YES in step S12), the process proceeds to step S13. On the other hand, if the magnetic pole position sensor 7 does not generate a pulse signal (NO in step S12), the process proceeds to step S15 to execute this process. In the process of step S <b> 13, a signal for braking the motor 5 is generated, and the generated signal is output to the motor 5 via the motor drive / speed control unit 17. After performing the process of step S13, it transfers to the process of step S14.

  In the process of step S14, it is determined whether or not the door 2 is in a stopped state. If the door 2 is in a stopped state (YES in step S14), the process proceeds to step S15. On the other hand, if the door 2 is not stopped (NO in step S14), the process returns to step S12 and this process is repeated again.

  When the door 2 is in a stopped state and the process proceeds to step S15, the control of the motor 5 is stopped in the process of step S15. Here, stopping the control of the motor 5 means that the power supply to the motor 5 is cut off by the operation of the power cut-off unit 48 or the output of the door open / close signal to the motor 5 is stopped. The former is adopted (the latter may be adopted). It is assumed that the power supply to the door controller 42 and the magnetic pole position sensor 7 is maintained even if the power supply to the motor 5 is cut off. When the control of the motor 5 is stopped, the operation state of the device appears to be stopped (in a state where the power is kept on, the operation is apparently the same as when the power is turned off). After performing the process of step S15, it transfers to the process of step S16.

  In the process of step S16, it is determined whether or not the operation stop switch 43 has been turned off. If the operation stop switch 43 is turned off (YES in step S16), the process proceeds to step S17. On the other hand, if the operation stop switch 43 is not turned OFF (NO in step S16), the process proceeds to step S19, and the manual opening / closing process is executed.

  In the process of step S <b> 17, canceling the apparently stopped apparatus operating state is executed together with the subsequent process of step S <b> 18. Specifically, transmission of a pilot lamp lighting signal (not shown) is started, the power shut-off unit 48 is operated to restart the power supply to the internal sensor 21, the external sensor 22, and the safety light switch 23, or the internal sensor 21 or starts receiving input from the external sensor 22 or the safety light switch 23 (step S17). In addition, the control of the motor 5 is started (step S18). After performing the processing of step S17 and step S18, it returns to the processing of step S2 in FIG. 3 assuming that the operation stop processing is completed, and repeats the processing of step S2.

  1 and 5, when the process proceeds to the manual opening / closing process, the process of step S21 is first executed. In step S21, it is determined whether or not the magnetic pole position sensor 7 is generating a pulse signal, in other words, whether or not the door 2 is being manually opened and closed. If the magnetic pole position sensor 7 is generating a pulse signal (YES in step S21), the process proceeds to step S22. On the other hand, when the magnetic pole position sensor 7 does not generate a pulse signal (NO in step S21), it is determined that manual opening / closing is not performed, and the process returns to step S16 in FIG. The process of S16 is repeated again.

  In the process of step S22, it is determined whether or not the door 2 is moved in the closing direction. If the door 2 is moved in the closing direction (YES in step S22), the process proceeds to step S23. On the other hand, when the door 2 is moved in the opening direction (NO in step S22), the process proceeds to step S24.

  In the process of step S <b> 23, it is determined whether or not the door 2 moving in the closing direction is closest to the fully closed position of the door 2. When the door 2 that is moving in the closing direction is in the immediate vicinity of the fully closed position of the door 2 (YES in step S23), the process proceeds to step S25. On the other hand, when the door 2 moving in the closing direction is not closest to the fully closed position of the door 2 (NO in step S23), the process returns to the process of step S16 in FIG. 4, and the process of step S16 is repeated again. . The door 2 moving in the closing direction can be moved manually and smoothly until the door 2 comes close to the fully closed position.

  In the process of step S25, it is determined whether or not the door 2 moving in the closing direction is in the fully closed position of the door 2. If the door 2 moving in the closing direction is not in the fully closed position of the door 2 (NO in step S25), the process proceeds to step S27. On the other hand, when the door 2 moving in the closing direction is in the fully closed position of the door 2 (YES in step S25), the process proceeds to the locking / unlocking process in step S28. In addition, after the process of step S28 is complete | finished, it returns to the process of step S15 of FIG. 4, and repeats the process of this step S15 again. The reason why the process returns to the process of step S15 is that there is a process of step S27, and because the motor is temporarily in an operating state by the process of step S27 (the process proceeds to the process of step S17 after the process of step S28 is completed). Sometimes).

  In the case where the door 2 is moved in the opening direction, in the process of step S24, it is determined whether or not the door 2 moving in the opening direction is closest to the fully open position of the door 2. If the door 2 that is moving in the opening direction is closest to the fully open position of the door 2 (YES in step S24), the process proceeds to step S26. On the other hand, when the door 2 moving in the opening direction is not closest to the fully open position of the door 2 (NO in step S24), the process returns to step S16 in FIG. 4, and the process in step S16 is repeated again. The door 2 that is moving in the opening direction can be manually moved smoothly until it is close to the fully open position of the door 2.

  In the process of step S <b> 26, it is determined whether or not the door 2 moving in the opening direction is the fully open position of the door 2. When the door 2 that is moving in the opening direction is not in the fully open position of the door 2 (NO in step S26), the process proceeds to step S27. On the other hand, when the door 2 moving in the opening direction is the fully open position of the door 2 (YES in step S26), the process returns to the process of step S15 in FIG. 4 and the process of step S15 is repeated again. The reason why the process returns to the process of step S15 is that there is a process of step S27, and the motor is temporarily in an operating state by the process of step S27.

  The processing in step S27 aims at the following. In other words, when the door 2 is moved to a position where a finger is pinched, the pressing force that has been applied to the door 2 that has been moved smoothly and manually has suddenly increased. The purpose is to do. For this reason, in step S27, a signal (braking signal) for braking the motor 5 is generated, and the generated signal is output to the motor 5 via the motor drive / speed control unit 17. It should be noted that the braking in step S27 is not intended to be as strong as the processing in step S13 because it is necessary to consider manual operation. After executing the process of step S27, the process returns to the process of step S16 in FIG. 4, and the process of step S16 is repeated again.

  1 and 6, when the process proceeds to the locking / unlocking process, the process of step S31 is first executed. In the process of step S31, it is determined whether or not the lock switch 44 is turned on. If the lock switch 44 is not turned on (NO in step S31), the process proceeds to step S32. On the other hand, if the lock switch 44 is turned on (YES in step S31), the process proceeds to step S33. In the process of step S32, since there is no ON operation of the locking switch 44, an unlock signal is output and it transfers to the process of step S34. In the process of step S33, there is an ON operation of the lock switch 44. From this, a lock signal is output, and the process proceeds to step S34.

  In step S34, it is determined whether the magnetic pole position sensor 7 is generating a pulse signal. If the magnetic pole position sensor 7 is generating a pulse signal (YES in step S34), the process proceeds to step S36. On the other hand, when the magnetic pole position sensor 7 does not generate a pulse signal (NO in step S34), the process proceeds to step S35.

  In the process of step S35, it is determined whether or not the operation stop switch 43 has been turned OFF. If the operation stop switch 43 is turned off (YES in step S35), the locking / unlocking process step S28 is terminated, and the process proceeds to the process of step S17 in FIG. On the other hand, when the operation stop switch 43 is not turned off (NO in step S35), the process returns to step S31, and the process of step S31 is repeated again.

  In the process of step S36, it is determined whether a predetermined number of pulse signals from the magnetic pole position sensor 7 have been counted. If a predetermined number of pulse signals from the magnetic pole position sensor 7 have been counted (YES in step S36), the process proceeds to step S37. On the other hand, if the predetermined number of pulse signals from the magnetic pole position sensor 7 have not been counted (NO in step S36), the process returns to step S34, and the process in step S34 is repeated again.

  In the process of step S37, it is determined whether or not a locking signal is output. If the locking signal is output (YES in step S36), the process proceeds to step S38. On the other hand, if the locking signal is not output (NO in step S37), the process returns to step S15 in FIG. 4 and the process in step S15 is repeated again.

  With respect to steps S36 to S37, in these processes, it is determined whether or not illegal intrusion has occurred. Specifically, when the electric lock 34 is in the locked state (when the locking signal is being output), there should be no generation of a pulse signal. However, when the control calculation unit 45 counts a predetermined number of pulse signals. It is thought that illegal intrusion has occurred. In steps S36 to S37, the alarm signal generation determination unit 52 operates. Note that the predetermined number is a number sufficient to determine that the intrusion has occurred and is an arbitrary number.

  In the process of step S38, since it is considered that illegal intrusion has occurred, a process of generating an alarm signal and outputting it to the transmission target device is executed. When the transmission target device receives the alarm signal, it threatens the intruder with an alarm sound and strong light emission, and activates the security camera 54 (see FIG. 2) for identifying the illegal intruder to start shooting and recording. It becomes like this. In step S38, the warning signal generation determination means 52 and the warning signal output means 53 are activated.

  More specifically, when a suspicious person tries to forcibly open the door 2 using, for example, a bar, the automatic door device 41 causes the restraining rod of the electric lock 34 to be a motor pulley groove (not shown) by the force of the bar. There is a risk that it will come out of the box and become unlocked. If the door 2 is forcibly opened, illegal intrusion is possible. In such an unauthorized unlocking state of the automatic door device 41, the door controller 42 detects the pulse signal from the magnetic pole position sensor 7 and counts it even though it outputs the locking signal. It operates as follows.

  When the door controller 42 counts a predetermined number of pulse signals in the locked state, the door controller 42 determines that a suspicious person has illegally entered the door 2, and has a security light 56 with an alarm installed on the ceiling near the door 2 (FIG. 2). 2) and a security camera recorder 55 with a liquid crystal monitor (see FIG. 2) installed in the manager's room. The alarm-equipped crime prevention light 56 emits powerful light and also emits an alarm sound to threaten illegal intruders. The security camera recorder 55 with a liquid crystal monitor records a video from a security camera 54 (see FIG. 2) installed on the ceiling near the door 2 (although it is not particularly limited, the security camera recorder 55 with a liquid crystal monitor). Is to stop recording until an alarm signal is input, whereas the security camera 54 always displays video).

  As described above with reference to FIGS. 1 to 6, according to the present invention, the automatic door device 41 is operated by turning on the operation stop switch 43 in order to turn the power switch off. It is possible to apparently stop the driving state. Even if the operation stop switch 43 is turned ON and the device operation state is apparently stopped, the power supply to the door controller 42 and the electric lock 34 is maintained, so that the electric lock 34 can be used for locking and unlocking. It can be done well.

  In addition, according to the present invention, even if the operation stop switch 43 is turned on and the device operation state is apparently stopped, the power supply to the door controller 42 and the magnetic pole position sensor 7 is maintained. The electric lock 34 can be operated only when it is in a position to be locked / unlocked, and security measures can be taken using the pulse signal from the magnetic pole position sensor 7.

  Regarding crime prevention measures, according to the present invention, an alarm necessary for crime prevention measures is determined according to the pulse signal output for position detection during the opening / closing operation of the door 2 and the control state of the electric lock 34 controlled by the door controller 42. The door controller 42 (alarm signal generation determination means 52) determines whether or not a signal needs to be generated. The door controller 42 (alarm signal generation determination means 52) generates an alarm signal and transmits it when it is determined that an alarm signal needs to be generated.

  According to the present invention, security measures can be taken without newly installing dedicated parts. By configuring the door controller 42 as in the present invention, an alarm signal used for security measures can be output.

  It goes without saying that the present invention can be variously modified without departing from the spirit of the present invention.
