Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic door system, and more particularly to a technique for notifying an abnormality of a device (node) by data communication.

The schematic diagram of FIG. 8 shows a sensor of a general automatic door of blind mounting type. Many sensors for automatic doors have a relay output, and LEDs (light emitting diodes) for displaying operation are provided on the housing.

When the sensor detects an object to be detected (a moving object such as a person), it displays the detection status with the operation display LED and at the same time notifies the door controller of the detection through a relay output, and the door controller responds to the information. The door is opened and closed based on the above (see, for example, Patent Document 1).

The sensor usually has a self-diagnostic function, and when it determines that a failure (abnormality) has occurred in the sensor itself, the operation display LED will display a failure to notify the surroundings, and the door Safety is ensured by outputting a door open signal to the controller to open the door.

Door controllers also have self-diagnostics. However, since the door controller is usually installed inside the frame of the automatic door (for example, in the Mumenai), if the door controller malfunctions or becomes unstable, the situation is notified to the surrounding people. Can not do it.

Even if the door controller fails or becomes unstable, the door is left open to ensure safety. Therefore, it is not possible to encourage immediate inspection and replacement.

In this way, in addition to the door controller, the system of the automatic door system includes, for example, a photoelectric sensor controller and a wireless touch switch receiver, which are installed in a hidden location and are accessible to the user. There are devices that do not have an external notification function, such as LEDs and buzzers, in places where they can be seen.

If a device such as a controller or sensor that does not have a notification function that the user can see or hear (a device that cannot be notified) breaks down, the user may be unaware of the failure and may be exposed to danger.

In addition, even in the case of devices such as controllers and sensors (devices capable of reporting) that have reporting functions such as LEDs and buzzers for reporting to the outside, if the reporting function itself breaks down, the user will not be able to Being unaware of the failure can put you at risk.

The microcomputer 310 obtains the reflection level from the amount of received light, compares it with a predetermined threshold value, and determines the presence or absence of an object (person).

For example, if the reflection level is equal to or higher than the threshold, it is determined that there is a person, and a "Hi" signal is output. The "Hi" and "Lo" signals are sent from the CAN communication transceiver 360 to the door controller 20 via the CAN 101 communication line.

The LED 351 has R (red), G (green), and B (blue) light-emitting elements, and lights predetermined light-emitting elements according to a detection signal from the microcomputer 310 . For example, in the case of a "Hi" signal indicating that there is a person present, R (red) is lit, and in the case of a "Lo" signal indicating that there is no person present, G (green) or B (blue) is illuminated. The buzzer 352 is made to ring in order to inform the user when, for example, a node (equipment) fails (abnormality). The LED 351 is arranged at a conspicuous position, and the buzzer 352 is arranged at a position where people around can hear it.

The touch sensor 50 comprises a wireless touch plate transmitter 51 on the transmitting side and a wireless receiver 52 on the receiving side. As shown in FIG. 2, a wireless touch plate transmitter 51 is provided on the door 10 and a wireless receiver 52 is located within the blind 11 .

The wireless touch plate transmitter 51 includes a microcomputer 511 as control means, a push switch 512 pressed by the touch plate 512a, a wireless transmitter 513, an LED display 514, an ID setting switch 515, and a battery 516. ing.

When the touch plate 512 a is pressed and the push switch 512 is turned on, for example, the microcomputer 511 lights the LED indicator 514 and transmits a “door open” signal from the wireless transmitter 513 to the wireless receiver 52 . The microcomputer 511 also has a self-diagnosis function.

An ID for self-identification for data communication is set in the microcomputer 511 by the ID setting switch 515 , and a sender ID used in an anomaly notification protocol, which will be described later, is also set in the microcomputer 511 by the ID setting switch 515 .

The wireless receiver 52 includes a microcomputer 521 as control means, a wireless receiver 522 , a CAN communication transceiver 523 , an ID setting switch 524 and a power supply circuit 525 .

When the wireless receiver 522 receives the “door open” signal, the microcomputer 521 transmits the “door open” signal to the door controller 20 via the CAN communication transceiver 523 and CAN 101 . This microcomputer 521 also has a self-diagnostic function, but the wireless receiver 52 does not have an informing means such as an LED or a buzzer for informing the outside (people in the vicinity, etc.).

An ID for self-identification for data communication is set in the microcomputer 521 by the ID setting switch 524 , and a sender ID used in an anomaly notification protocol, which will be described later, is also set in the microcomputer 521 by the ID setting switch 524 . The power circuit 525 is connected to the power line in the CAN 101 .

As described above, according to this embodiment, each of the nodes of the door controller 20, the controller 41 of the photoelectric sensor 40, and the wireless receiver 52 of the touch sensor 50 has a self-diagnostic function and also has an external notification means. not Therefore, if a failure (abnormality) occurs in these nodes, the user may not notice it and the failure state may be left unattended for a long time.

Therefore, in the present invention, a communication network 100 (CAN 101 in this embodiment) to which each node is connected is used to notify a failure of a node that does not have a means of reporting to the outside, and a node that has a means of reporting to the outside. I am trying to let you know by using the function.

In this specification, a node that does not have means for reporting to the outside is referred to as an "unreportable node", and a node that has means for reporting to the outside is referred to as a "node capable of reporting".

Depending on the model, for example, an LED for maintenance may be provided inside the housing of the door controller. be Node failures include all abnormal states such as anomalies, operation errors, and malfunctions detected by the microcomputer.

Therefore, the communication protocol of the CAN 101 includes an anomaly notification protocol. As an example, FIG. 7 shows an anomaly notification protocol set in the door controller 20, which is one of the nodes that cannot be notified. The anomaly notification protocol includes source ID, destination ID, notification method, importance, light emission cycle, duty ratio, and light emission color.

In this example, the ID of the reflective sensor 30, which is a node that can be notified, is ID (1), and the ID of the door controller 20 is ID (10). "10" for destination ID, "1" for destination ID, "LED" for notification method, "1" for priority, "100 msec" for light emission cycle, “50%” is specified in the item of duty, and “red” is specified in the item of color.

Therefore, when a failure occurs in the door controller 20, the R element among the LEDs 351 provided in the reflection sensor 30 (30a, 30b) blinks with a light emission period of 100 msec and a duty ratio of 50%. When the buzzer is set as the notification method, the buzzer 352 of the reflective sensor 30 (30a, 30b) sounds.

The LED of only one of the indoor sensor 30a and the outdoor sensor 30b in the reflection sensor 30 can be lit. Normally, the wireless touch plate transmitter 51 has only a transmission function, and the wireless receiver 52 has only a reception function, but as shown in FIG. Alternatively, the radio transmitter 526 may be mounted on the wireless receiver 52 side, and the LED indicator 514 provided in the wireless touch plate transmitter 51 may be turned on as an abnormality notification means by another node that has detected an abnormality.

Further, in preparation for a failure of the reportable node, the indoor sensor 30a and the outdoor sensor 30b of the reflective sensors 30 may also be set with an abnormality reporting protocol. For example, the ID of the outdoor sensor 30b is written as the destination in the abnormality notification protocol for the indoor sensor 30a, and the ID of the indoor sensor 30a is written as the destination in the abnormality notification protocol for the outdoor sensor 30b. .

According to this anomaly notification protocol, priority is assigned as importance. Therefore, when notification instructions are received from a plurality of nodes at the same time, the node capable of notification performs notification with high priority.

In addition, as the notification function, in addition to light and sound, information terminal equipment using wireless communication such as Bluetooth (registered trademark) can be used for notification, and such a mode is also included in the present invention.
