Both of them (hereinafter, when referring to both the light projecting means 1 and the light receiving means 2 are collectively referred to as passenger detection means including these), there is no malfunction or the like, and they are operating normally. For the four modes when the light-projecting means 1 and the light-receiving means 2 installed as a light-shielding device are shielded or not shielded, and when the light-projecting device 1 is stopped and operating. It shows the operation mode of the light receiving means and what happens to the operation state of the elevator door due to the operation of the light receiving means,
This will be described below.

扉状態を保持する。As shown in FIG. 2, the operation mode of the light receiving means 2 with respect to the operation state of the light projecting means 1 is that the light projecting means 1 is in the operating state and the light from the light projecting means 1 is not blocked and is not shielded. At times, the output unit 9 of the light receiving means 2 enters a mode for holding and outputting the OFF state, and as a result, the door of the elevator is controlled to start the operation of closing the door when the door is open. When the operating state of the light projecting means 1 is other than the above, that is, the light projecting means 1 is in the operating state,
When the light from the light projecting means 1 is blocked, when the light projecting means 1 is in the non-light-shielding state or when the light projecting means 1 is in a non-light-shielding state, the operation mode of the light receiving means 2 is the output section 9 of the light receiving means 2.
Is in a mode for holding the ON state, and as a result, the operating state of the elevator door is exactly the same as when the light is shielded, and the opened state is held.

かを示しており、以下、これについて説明する。FIG. 3 shows the operation mode of the light receiving means when the light emitting means 1 has a failure and the light receiving means 2 is normal, and what happens to the operating state of the elevator door due to the operation of the light receiving means. This will be described below.

低下する。As shown in FIG. 3, when the failure mode of the light projecting means 1 becomes inoperative, including a power stop accident, a disconnection in the light projecting means, a failure of parts, etc., the light cannot be projected but the light is received. Since the means 2 is the same as when the light is shielded, the output part of the light receiving means 2 is in the mode for holding the ON state. As a result, the operating state of the door of the elevator is kept open. This failure mode is fail-safe in terms of elevator safety, but the door cannot be closed unless the close button in the car is pressed, so serviceability is significantly reduced.

段１が投光不能の場合と同様となる。The failure mode of the light projecting means 1 is the power source,
In the case of a half-break in the light projecting device or an ON-OFF intermittent failure of a component or the like, the light projecting device 1 is in an operation mode in which it is not determined whether light can be projected or not. When the light projecting means 1 is capable of projecting light, the light receiving means 2 can operate as in the normal state. As a result, the operation state of the elevator door is maintained in the open state when the light is shielded, and when the door is not shielded, the closing operation is started if the door is in the open state. When the light projecting means 1 cannot project light, the operation states of the light receiving means 2 and the elevator door are the same as those when the light projecting means 1 is unable to project light.

い。Further, when the failure mode of the light projecting means 1 is, for example, that the light emitting diode for projecting light is turned on, the light can be projected but the light cannot be modulated. However, the light receiving means 2 can detect passengers at the same level as in normal operation, and the safety and serviceability of the elevator can be greatly reduced. I won't.

If the light receiving means 2 fails, the operation mode of the light projecting means 1 is not affected at all. Therefore, each failure mode of the light receiving means 2 will be described below.

全性が大幅に低下したものとなる。As shown in FIG. 4, when a failure occurs in the mode in which the light receiving means 2 becomes inoperative, such as the power supply to the light receiving means 2 being turned off or the output section 9 being turned off, an output section 9 of the light receiving means 2 is generated.
Remains in the OFF state, even if the light from the light projecting means 1 is blocked, the light receiving means 2 cannot emit an output, that is, the passenger detection means can detect the passengers. Therefore, the elevator is in a fail-out state, and the door is in a significantly reduced safety state.

る。Further, when a failure mode occurs in which the light receiving section 7 cannot receive light due to a failure such as a disconnection in the light receiving section 2, the output section 9 of the light receiving section 2 remains in the ON state. The operation is the same as when the light is shielded, and as a result, the operation state of the elevator door is maintained in the open state. This failure mode is fail-safe in terms of elevator safety, but the door cannot be closed unless the close button in the car is pressed, which greatly reduces serviceability.

としては安全性が大幅に低下したものとなる。Further, similarly to the above, even if the light receiving section 7 cannot receive light due to a failure such as a disconnection in the light receiving means 2, in the case where the output section maintains the OFF state, the light is projected. Even if the light from the means 1 is shielded, the light receiving means 2 cannot output an output, and as in the above, the elevator is in a fail-out state, and the safety of the door is greatly reduced as the operating state. Will be things.

It is possible to perform the same operation as in the normal state. On the other hand, OFF
In the event of a failure, even if the light from the light projecting means 1 is blocked, the light receiving means 2 cannot output, and the elevator is in a fail-out state, and the safety of the door is greatly reduced as the operating state. It will be what you did.

ある。Summarizing the above-mentioned results, from the operating state of the elevator door, the fatal failure modes in terms of safety and serviceability are the power failure of the light receiving means 2, the OFF failure of the output part 9 of the light receiving means 2, etc. The failure mode in which the serviceability is deteriorated is the case in which the failure mode of the light projecting unit 1 becomes inoperative including the stop of the power supply, and the inside of the light receiving unit 2. This is a case where a failure mode occurs in which the light receiving unit 7 becomes unable to receive light due to a failure such as disconnection.
【００２４】従って、前述した致命度のレベルに沿って

ドである。Whether or not the failure mode is a fatal problem in the determination of step 513 is shown in FIG.
It is determined by the criteria described with reference to FIG. Specifically, the most fatal failure mode is a failure in a mode in which the light receiving unit itself becomes inoperative, such as "power failure of the light receiving unit 2 and OFF failure of the output unit 9", and is not fatal. The failure mode in which there is no serviceability is that the light receiving unit 7 cannot receive light when "the light projecting means 1 is inoperative even when the power supply is stopped" and when "a failure such as disconnection in the light receiving means 2". It is a failure mode. Further, the failure mode accompanied with slight deterioration in serviceability and function is a failure mode of "ON failure of the light projecting means 1".
