  The duplication unit 63 copies the information stored in the update storage unit 53 and stores it in the accumulation storage unit 54 when the timing unit 62 finishes counting the predetermined time. The duplication of information by the duplication unit 63 is performed in the accumulation storage unit 54 by using information on all areas stored in the update storage unit 53 at the time of duplication as one piece of information. In the storage unit 54, information is stored in a different recording area for each copy.

  When the information is stored in all the recording areas of the storage unit 54, the prohibiting unit 64 prohibits subsequent information storage. That is, the storage unit 54 is configured so that stored data cannot be rewritten. Then, the prohibiting means 64 outputs a signal notifying that the information storage is prohibited. This signal is input to the notification unit 57, and the notification unit 57 displays on the LCD in response to the input of this signal.

  As shown in FIG. 9, the automatic door controller 12 and each control device 14, 16, 18, 20 output control information 40 together with identification ID information 41 and end information 42 (step ST1). This control information 40 is transmitted on the data bus 30. On the other hand, when the control information 40 on the data bus 30 is received (step ST2), necessary information is extracted from the control information 40 (step ST3), and the control operation according to the extracted control information 40 is performed. Perform (step ST4). This is then repeated.

  On the other hand, as shown in FIG. 10, in the data logger 26, when control is started, the extension timer is first reset, and when the extension timer is operating, it is stopped (step ST11). Then, it is determined whether or not the control information 40 is received from the data bus 30 (step ST12). When the control information 40 is received, the process proceeds to step ST13.

  In step ST13, the received control information 40 is recorded as a log in the update storage unit 53 together with the reception time. And it is determined whether abnormality information is contained in the recorded control information 40, or it corresponds to the specific event set beforehand (step ST14). If none of the above applies, the process proceeds to step ST15, the storage position in the update storage unit 53 is incremented (step ST15), and it is determined whether or not the timer value of the extension timer is equal to or greater than a predetermined time X (step). ST16). Since the extension timer is reset at the start, first, the process proceeds to step ST17. Then, it is determined whether or not the storage position in the update storage unit 53 has reached the tail (step ST17). If it has not reached the tail, the process returns to step ST12, and if it has reached the tail, the storage position is determined. After changing to the head position (step ST18), the process returns to step ST12.

  Steps ST12 to ST17 are repeated every time control information 40 is received. While this step is repeated, if abnormality information is detected in the control information 40, or if it corresponds to the specific event, the determination in step ST14 is YES, so the process proceeds to step ST19 and is extended. Start counting by the timer. The above steps are repeated until the time measured by the extension timer reaches the predetermined time X. That is, even when abnormality information is detected, the reception of the control information 40 is continued for a predetermined time X. When the time measured by the extension timer exceeds the predetermined time X, the process proceeds from step ST16 to step ST20.

  In step ST20, the extension timer is stopped and reset, and it is confirmed whether or not the storage position in the storage unit 54 has reached the end (step ST21). If the storage position has not reached the end, all the logs stored in the update storage unit 53 are copied and stored in the storage unit 54 (step ST22). That is, when abnormality information is detected, the control information 40 received within a predetermined time X before and after the detection is recorded in the accumulation storage unit 54. At this time, the logs are sorted and stored in order of time.

  Then, the storage position in the storage unit 54 is incremented (step ST23), and all the logs in the update storage unit 53 are cleared (step ST24). When all the logs are cleared, the process moves to step ST18 and the storage position in the update storage unit 53 is changed to the head position.

  On the other hand, when the storage position in the storage unit 54 reaches the end, the process proceeds from step ST21 to step ST25, prohibiting the storage of information in the storage unit 54, and a message to that effect is displayed on the LCD.

Furthermore, since the data logger 26 is configured to sequentially store the control information 40, this effectively uses the information that is included in the control devices 14, 16, 18, 20, etc. as well as the automatic door controller 12. This makes it possible to quickly respond to defects. For example, in the present embodiment, the detection status of each spot area in the detection area of each activation sensor 14, 16 is accumulated, so that more detailed diagnosis can be performed by utilizing this accumulated information. Can do. In addition, since it is not necessary to store all of the control information 40 in the automatic door controller 12, it is not necessary to raise the specifications of the automatic door controller 12 in order to receive and store all of this information, thereby increasing the cost of the automatic door controller. Can be avoided.

  Further, in the present embodiment, since it is possible to determine whether or not there is a specific event or abnormality information in the data logger 26, it is possible to detect the occurrence of an abnormal state or failure based on the information accumulated in the data logger 26. .

  Further, in the present embodiment, the information once stored in the update storage unit 53 is duplicated and stored in the accumulation storage unit 54. Therefore, the update storage unit 53 stores the information in the update storage unit 53 while continuing to update the information. The information can be stored in the storage unit 54. Therefore, necessary information can be reliably saved while avoiding the storage capacity of the update storage unit 53 becoming very large.

  In the present embodiment, the information in the update storage unit 53 is written in the accumulation storage unit 54 when a predetermined event X is established or when a predetermined time X has elapsed since the abnormality information was detected. Information such as when it is established can be reliably stored. In addition, since the information stored after a specific event is established, etc., it is possible to check not only the cause but also the subsequent operation status and increase the amount of information that can be used effectively. .

  In the present embodiment, the data logger 26 includes prohibition means 64 that prohibits overwriting of the information stored in the storage unit 54, so that important information such as when a specific event is established is surely lost. Can be prevented.

  The present invention is not limited to the present embodiment, and various changes and improvements can be made without departing from the spirit of the present invention. For example, the adjuster 20 may be connected to the bus 30 wirelessly.

  In the present embodiment, the auxiliary sensor 24 is connected to the automatic door controller 12, but the auxiliary sensor 24 may be connected to the data bus 30 instead. However, in this case, it is necessary to mount a microcomputer or the like so that the control information 40 can be transmitted to and received from the auxiliary sensor 24. The auxiliary sensor 24 in this case is configured to be able to transmit and receive information related to the operation control of the automatic door, and corresponds to a control device that operates in cooperation with the automatic door controller 12.

  In the present embodiment, when the log in the update storage unit 53 is copied to the accumulation storage unit 54, the log in the update storage unit 53 is deleted. However, the present invention is not limited to this.
