It is possible to emit light. That is, the power switch 30 includes an operated portion 30a that emits light, and a light emitting device 30b that includes a light emitting device. Here, the blind 14 covers the front side of the automatic door 10 with respect to the operated portion 30a, and also functions as a light blocking portion that blocks the light emitted by the light emitting device 30b. That is, the operated portion 30a is arranged at a position where it is difficult to see from the front of the automatic door 10, but can be seen from below the automatic door 10 as shown in FIG. The light-emitting device 30b lights up when the power switch 30 is in a state of supplying electric power to the driving device 20 from the outside of the driving device 20, and the automatic door 10 is in a "normal state" described later.

FIG. 6 is a diagram showing the relationship between the failure-related state of the automatic door 10, the operating state of the automatic door 10, and the light emission pattern of the light emitting device 30b.

As states related to the failure of the automatic door 10, there are a "normal state" and an "abnormal state". The "abnormal state" includes, for example, a "high probability of failure state" indicating a state in which a failure of the automatic door 10 is likely to occur, and a "failure state" indicating a state in which the automatic door 10 has failed. ” exists.

Examples of the "high probability of failure state" include a "specific open/close number state" indicating that the automatic door 10 has been opened and closed a specific number of times, "Open time change state" indicating that it has changed for a specific time or longer, and that a warning has been received from any of the start sensor 15, start sensor 16, and auxiliary photoelectric sensor 17 connected to the controller 29 by CAN communication. "CAN sensor warning state" indicating that the controller 29 detected an overload each time during three consecutive opening operations, and "open overload state" indicating that the controller 29 detected an overload each time during three consecutive opening operations, and the controller 29 There is a "closed overload condition" which indicates that the has detected an overload each time.

The driving device 20 usually fails after being opened and closed for a substantially constant number of times from an unused state. Therefore, when the number of times the automatic door 10 is opened and closed reaches a specific number of times, there is a high possibility that the automatic door 10 will fail in the near future. The "specific number of opening/closing state" is a state in which such a failure is highly likely to occur.

The fact that the opening time of the door 11 of the automatic door 10 has changed from the normal time by more than a specific time means that the automatic door 10 has not failed, but some kind of abnormality has occurred in the automatic door 10. be. Therefore, if the opening time of the door 11 of the automatic door 10 changes from the normal time by more than a specific time, there is a high possibility that the automatic door 10 will fail in the near future. The "open time change state" is a state in which such failures are likely to occur.

If any one of the activation sensor 15, the activation sensor 16, and the auxiliary photoelectric sensor 17 receives a warning, there is a high possibility that any one of the activation sensor 15, the activation sensor 16, and the auxiliary photoelectric sensor 17 will notify an abnormality in the near future. . That is, if any one of the activation sensor 15, the activation sensor 16, and the auxiliary photoelectric sensor 17 receives a warning, an abnormality will be notified from any of the activation sensor 15, the activation sensor 16, and the auxiliary photoelectric sensor 17 in the near future. There is a high possibility that the automatic door 10 will fail. A "CAN sensor warning state" is a state in which such a failure is likely to occur.

The occurrence of an overload in the opening operation of the automatic door 10 means that there is abnormal resistance to the movement of the door 11 in the opening operation of the automatic door 10 . Therefore, if the controller 29 detects an overload every time the door is opened three times in succession, there is a high possibility that the automatic door 10 will fail in the near future. An "open overload condition" is a condition in which such a failure is likely to occur.

Similarly, if the controller 29 detects an overload every time the door is closed three times in succession, there is a high possibility that the automatic door 10 will fail in the near future. A "closed overload condition" is a condition in which such a failure is likely to occur.

The "failure state" includes, for example, a "microcomputer runaway state" indicating a state in which an abnormality in the processing of the controller 29 such as noise occurs, and a power source external to the controller 29, for example, 12V, from the controller 29. An "external power cutoff state" indicating a state in which the external power supplied to the activation sensor 15, the activation sensor 16, the auxiliary photoelectric sensor 17, and the light emitting device 30b is cut off, and the activation sensor connected to the controller 29 via CAN communication. 15. "CAN sensor error state" indicating that the abnormality of the sensor itself is notified from either the start sensor 16 or the auxiliary photoelectric sensor 17, "EEROM abnormal state" indicating the state that the EEPROM 29c is abnormal, and SUM check "CPU error state" indicating a state in which a physical abnormality has occurred in the CPU 29a detected by the "motor error state" indicating a state in which an abnormality has occurred in the motor 27, and unlocking of the electric lock 28 An "electric lock unlocking error state" indicating a state in which an abnormality has occurred, an "overcurrent detection state" indicating a state in which the controller 29 has detected an overcurrent in the motor 27, and a 15V voltage inside the controller 29, for example. An "internal power cutoff state" indicating a state in which the internal power source for driving the motor 27 is cut off, and an "abnormal stroke state" indicating a state in which the stroke of the door 11 of the automatic door 10 is abnormal. exists.

Here, the overcurrent of the motor 27 regarding the "overcurrent detection state" will be described.

FIG. 7 is a diagram showing an example of the moving speed of the door 11 when opened by the motor 27. As shown in FIG.

As shown in FIG. 7, when the closed door 11 is opened by the motor 27, the controller 29 causes the motor 27 to accelerate the moving speed of the door 11 from zero to v1 from time zero to time t1, The moving speed of the door 11 is maintained at the speed v1 by the motor 27 from the time t1 to the time t2, and the moving speed of the door 11 is reduced from the speed v1 to the speed v2 from the time t2 to the time t3. , the moving speed of the door 11 is maintained at v2 by the motor 27 from time t3 to time t4, and the moving speed of the door 11 is reduced from v2 to zero by the motor 27 from time t4 to time t5. do.

The controller 29 calculates the average value of the current values of the motor 27 from time zero to time t5 as the average value of the current values of the motor 27 in the entire opening operation of the automatic door 10, and calculates the average value is greater than a specific value with respect to the normal average value, it is detected as an overcurrent of the motor 27 .

In the above, the controller 29 detects overcurrent of the motor 27 based on the average current value of the motor 27 from time zero to time t5. However, the controller 29 may detect overcurrent of the motor 27 based on a value other than the average current value of the motor 27 from time zero to time t5. For example, the controller 29 acquires the peak value occurring between time 0 and time t1 as the peak value of the current value of the motor 27 in one operation of opening the automatic door 10, and when this peak value is normal It may be detected as an overcurrent of the motor 27 when it is greater than a specific value with respect to the peak value of .

Next, the relationship between the failure-related state of the automatic door 10 and the operating state of the automatic door 10 will be described with reference to FIG.

When the controller 29 determines that the state related to the failure of the automatic door 10 is the "normal state", the controller 29 causes the automatic door 10 to perform normal operation.

The controller 29 causes the automatic door 10 to perform normal operation even when it determines that the state related to the failure of the automatic door 10 is the " high possibility of failure state".

The controller 29 resets itself when the "microcomputer runaway state" occurs. When the controller 29 itself is reset, the controller 29 cannot cause the automatic door 10 to perform normal operation until the initial operation after the reset is completed. That is, the automatic door 10 is stopped when the "microcomputer runaway state" occurs.

The controller 29 has three states: "external power cutoff state", "CAN sensor error state", "EEROM error state", "CPU error state", "motor error state", "electric lock unlocking error state", and "overcurrent detection state". , , , , , , , , , , , , , or , , , , , , , , , , , , , , , , , , , , , , the automatic door 10 is stopped.

The controller 29 turns off the light-emitting device 30b during the initial operation after reset due to the occurrence of the "microcomputer runaway state", and turns on the light-emitting device 30b after the end of the initial operation. Note that the controller 29 lights the light-emitting device 30b during the initial operation other than the initial operation after reset due to the occurrence of the "microcomputer runaway state".

When the "external power cutoff state" occurs, the light emitting device 30b is also turned off because power is not supplied to the light emitting device 30b. After the occurrence of the "external power cut-off state", the controller 29 performs flashing (hereinafter referred to as " flashing for a very short lighting time") is repeated for a specific period of time by the light emitting device 30b.

When the controller 29 determines that the "CAN sensor error state" has occurred, the controller 29 performs flashing (hereinafter referred to as "short ) is repeated by the light emitting device 30b. The activation sensor 15, the activation sensor 16, and the auxiliary photoelectric sensor 17 also flash in a specific light emission pattern by their own light emitting units (not shown) when an abnormality occurs in the sensor itself.

When the controller 29 determines that the "EEROM abnormal state" has occurred, the controller 29 lights up twice with a duration of 0.3 seconds and turns off with a duration of 0.3 seconds in between. After the execution, the light emitting device 30b repeats the flashing of extinguishing for 3 seconds (hereinafter referred to as “short lighting time flashing twice”).

As shown in FIG. 9, the controller 29 determines the current status of the failure-related status of the automatic door 10 (S61).

Next, the controller 29 identifies the light emission pattern associated with the state determined in S61 in the correspondence information 29e (S62).

Next, the controller 29 causes the light emitting device 30b to start emitting light in the light emitting pattern specified in S62 (S63).

Next, the controller 29 determines whether or not the light emission pattern specified in S62 is a light emission pattern associated with the "high probability of failure state" in the correspondence information 29e (S64).

When the controller 29 determines in S65 that it is necessary to cancel the light emission of the light emitting device 30b in the light emission pattern corresponding to the "high probability of failure state", it starts measuring time (S66 ).

The controller 29 determines in S64 that the light emission pattern is not associated with the "high probability of failure state", or the light emission pattern of the light emitting device 30b corresponding to the "high probability of failure state" is determined. If it is determined in S65 that the need to cancel is not set, or if the process of S66 is completed, it is determined whether or not time is being measured (S67).

As described above, the controller 29 causes the light emitting device 30b to emit light in the light emitting pattern shown in FIG. For example, if the state related to the failure of the automatic door 10 is one of the "high failure probability state" or any of the "failure state", the state of the power switch 30 is After the state of supplying electric power to the driving device 20 from the outside of the driving device 20 is switched to the state of cutting off the supply of electric power to the driving device 20 from the outside of the driving device 20, the state of the power switch 30 changes to the state of the driving device 20. When the state of cutting off the power supply from the outside of the automatic door 20 to the drive device 20 is switched to the state of supplying power to the drive device 20 from the outside of the drive device 20, the state related to the failure of the automatic door 10 is " If the controller 29 remains in any state in the "high failure probability state" or remains in any state in the "failure state", the controller 29 determines the state related to failure of the automatic door 10 in the "failure probability The current state of the automatic door 10 is determined (S61) from among the various states in the "high state" and the various states in the "failure state", and the state determined in S61 is associated in the correspondence information 29e. (S62), and light emission by the light emitting device 30b is started in the light emission pattern specified in S62 (S63).

The owner of the automatic door 10 and the service person of the automatic door maintenance company can recognize the abnormal state of the automatic door 10 by checking the light emission pattern of the light emitting device 30b. In particular, the owner of the automatic door 10 and the service person of the automatic door maintenance company can implement preventive maintenance of the automatic door 10 by recognizing the "specific opening/closing count state". In addition, the owner of the automatic door 10 and the service person of the automatic door maintenance company who performs the maintenance work of the automatic door 10 are aware of the "opening time change state", "CAN sensor warning state", "open overload state" or "closed state". Predictive maintenance of the automatic door 10 can be realized by recognizing the "overload condition".

As described above, the automatic door 10 causes the light emitting device 30b to emit light in a light emission pattern corresponding to each of the failure state as the abnormal state and the high failure probability state as the abnormal state. The user can be notified of multiple types of abnormal states. The user, for example, confirms a manual in which the correspondence shown in the correspondence information 29e is described, and from the light emission pattern emitted by the automatic door 10, which of the plurality of types of abnormal conditions is the automatic door 10. You can recognize what is happening.

The "specific opening/closing count state" is a state determined when the number of times the automatic door 10 has been used reaches a specific value. As the "high probability of failure state", there may be a state determined when the number of times of use of the automatic door 10 reaches a specific value in addition to the "specific number of times of opening/closing state". When the automatic door 10 notifies the state determined when the number of times of use of the automatic door 10 reaches a specific value as a high failure probability state by light emission from the light emitting device 30b, preventive maintenance of the automatic door 10 is performed. can support

As the "high probability of failure state", there may be a state determined when the operating time of the automatic door 10 reaches a specific value. When the automatic door 10 notifies the state determined when the operating time of the automatic door 10 reaches a specific value as a high failure probability state by light emission from the light emitting device 30b, preventive maintenance of the automatic door 10 is performed. can support

The "open time change state", "open overload state" and "closed overload state" are states determined based on the change in the value detected from the automatic door 10 from the normal state. In addition to the "open time change state", "open overload state" and "closed overload state", the "high probability of failure state" includes changes in the value detected from the automatic door 10 from the normal state. There may be conditions that are determined based on. When the automatic door 10 notifies the state determined based on the change from the normal state of the value detected from the automatic door 10 as the high failure possibility state by light emission from the light emitting device 30b, the automatic door 10 It can support predictive maintenance.

In the present embodiment, the automatic door 10 has the same light emission pattern by the light emitting device 30b in the "EEROM abnormal state" and the "CPU error state", but may be different. Similarly, the automatic door 10 has the same light emission pattern by the light emitting device 30b in the "open overload state" and the "closed overload state" in the present embodiment, but may be different.

The automatic door 10 may indicate a state other than the state exemplified in the present embodiment by emitting light from the light emitting device 30b with respect to the "high probability of failure state". Similarly, the automatic door 10 may indicate a state other than the state exemplified in the present embodiment by emitting light from the light emitting device 30b with respect to the "failure state".

The automatic door 10 may realize a plurality of light emission patterns by blinking timings other than the blinking timings exemplified in the present embodiment.

Since the automatic door 10 realizes a plurality of light emission patterns depending on the timing of blinking of the light emitted by the light emitting device 30b, compared to a configuration that realizes a plurality of light emission patterns only by the color of light emitted, the colors that can be emitted by the light emitting device 30b are different. can be reduced, and as a result, it can be realized at low cost.

Since the automatic door 10 makes the failure state shorter than the high failure possibility state with respect to the lighting duration of the blinking of the light emitted by the light emitting device 30b, the failure state having a higher urgency than the high failure possibility state It can be highlighted by flashing more intensely than in the high-probability state. In the automatic door 10, the failure state is made shorter than the high failure probability state with respect to the duration of extinguishing in the flashing of the light emitted by the light emitting device 30b, so that the failure state flashes more violently than the high failure probability state. You can make it stand out.

Even if the failure state is not flashed more violently than the high failure probability state, the automatic door 10 may determine at least one of the lighting duration and the extinguishing duration of the flashing of light emitted by the light emitting device 30b as the failure state. , and the high failure probability state, the user can easily distinguish between the failure state and the high failure probability state, which is less urgent than the failure state, and convenience can be improved. can.

When the automatic door 10 causes the light emitting device 30b to emit light in the light emitting pattern corresponding to the high failure possibility state (YES in S64), the automatic door 10 causes the light emitting device 30b to emit light in the light emitting pattern corresponding to the high failure possibility state. Since it is released at the release time (YES in S68 and S70), it is possible to prevent the user from being notified of the high failure possibility state, which is less urgent than the failure state, for a long period of time.

Although the automatic door 10 has a variable release time in the present embodiment, the release time may be fixed. In the present embodiment, the automatic door 10 can set whether or not it is necessary to cancel the light emission of the light emitting device 30b in the light emission pattern corresponding to the "high failure possibility state". The light emission by the light emitting device 30b in the light emission pattern corresponding to the "state" may be always canceled at the cancellation time, or the light emission by the light emitting device 30b in the light emission pattern corresponding to the "high possibility of failure state" may be canceled. Impossible configurations are also acceptable.

The automatic door 10 may indicate an abnormal state of the automatic door 10 by a light emission pattern other than the light emission pattern exemplified in the present embodiment. For example, the automatic door 10 realizes a plurality of light emission patterns by changing the color of light emitted by the light emitting device 30b instead of or in addition to the timing of blinking of light emitted by the light emitting device 30b. can be

When the automatic door 10 realizes a plurality of light emission patterns according to the color of the light emitted by the light emitting device 30b, the user can easily understand the light emission patterns compared to the configuration in which the plurality of light emission patterns are realized only by the timing of blinking the light emission. As a result, the user can easily recognize which of the multiple types of abnormal conditions has occurred in the automatic door 10 .

Since the automatic door 10 is provided with the blind 14 as a light shielding portion covering the front side of the automatic door 10 with respect to the operated portion 30a which is the light emitting portion of the light emitting device 30b, the light emitted by the light emitting device 30b is used to prevent the passage of the automatic door 10. It is possible to make it difficult to be visually recognized by a person by the eyes 14, and as a result, it is possible to reduce the possibility that the light emitted by the light emitting device 30b will be noticed by a passerby.

The automatic door 10 realizes both the function of indicating the state of the power switch 30 and the function of indicating the abnormal state of the automatic door 10 by means of the light emitting device 30b. The number of parts can be reduced compared to a configuration in which the light-emitting device 30b indicating the abnormal state of the light-emitting device 30b is provided separately.

The automatic door 10 may be provided with a light-emitting device that indicates an abnormal state of the automatic door 10 at a location other than the power switch 30 . For example, the automatic door 10 may include at least one of the activation sensor 15 and the activation sensor 16 with a light emitting device that indicates an abnormal state of the automatic door 10, or the automatic door 10 may include a light emitting device that indicates an abnormal state of the automatic door 10. It may be provided in an arbitrary place such as a mullion as a dedicated device for indicating the abnormal state of the device.

In the present embodiment, the automatic door 10 notifies both of the "high probability of failure state" and the "failure state" by emitting light from the light emitting device 30b. Only one of them may be notified by light emission from the light emitting device 30b.

As the sensors provided in the automatic door 10, the activation sensor 15, the activation sensor 16, and the auxiliary photoelectric sensor 17 are exemplified in the present embodiment. However, the automatic door 10 may be provided with sensors other than the activation sensor 15 , the activation sensor 16 and the auxiliary photoelectric sensor 17 . For example, the automatic door 10 may include a door pocket sensor for detecting objects present in the direction of travel of the door 11 when the door 11 is opened. Note that sensors other than the activation sensor 15, the activation sensor 16, and the auxiliary photoelectric sensor 17 are treated in the same manner as the activation sensor 15, the activation sensor 16, and the auxiliary photoelectric sensor 17 in various processes in the present embodiment.
